How to adjust the length of the conveyor belt installation

The conveyor belt , the installation is particularly important. To ensure correct installation of the belt can not only avoid unnecessary defects, and also allows the belt to

work better .
      When installing the conveyor advance Telescoping conveyors for the entire conveyor belt to be installed careful planning calculations, whether new or old belt replacement belt installed ,

otherwise it is likely to cause the situation to take a long conveyor belt , is a direct consequence weight ( weight counterweight ) hit the ground

Led start to slip . Although there was no problem , no problem test , but the position of the lower configuration , running two or three months later , with heavy drooping, hit

the ground when starting . This is Telescopic belt conveyor because the installation process does not take into account the elastic deformation and plastic deformation of the belt . Conveyor

When installing or too short , you should leave a margin for future maintenance. If the length of the minimum basic tension in the spiral . Joint problems after a period of use

, the conveyor belt margin is not sufficient to redo the joints, had to re- install the new belt. This makes our conveyor belt made

Become a go to waste . While enabling enterprises subject to certain unnecessary losses. This is what we want to see the production situation . Ideal conveyor installation is

that after installing the conveyor belt of moderate length ( we should take into account summer and winter temperature differences affect the expansion of the conveyor belt )

It is best to set aside a margin joints , which can effectively prevent the installation length of inappropriate questions .

How to maintain the relationship between the roller and the conveyor

Roller conveyor is an important component , the type , quantity , quality idlers direct impact on the quality of the conveyor . Roller conveyor forward rotation resistance and

resistance to the belt conveyor is mainly attributable to the resistance of 50% to 85%. The captain of the belt conveyor heavy duty conveyor over 80m total resistance is calculated , the total

Resistance to attacks such as the length of the conveyor in accordance with the selected charge coefficient , friction coefficient and installation simulation and working

conditions related to the length of the conveyor , carrying the rotating part of the mass per unit length of the branch roller rotating part of the quality return idler unit

length of the branch , conveyor units

Quality , delivery of materials per Power Roller Conveyor unit mass ( and conveyors capacity , material bulk density and tape speed related ) , roller forward friction parameters affecting the

special main drag and friction tape cleaner special additional resistance and so on. Wherein the rotating part of the quality roller bearing unit length of the branch back

Cheng branch roller mass per unit length of the rotating part and the main drag conveyor belt unit mass transport , should take full account of the selected rotational

resistance and conveyor idler indentation resistance , in order to more accurately calculate the tape running resistance .

Criteria for the selection of food conveyor belt speed of

    ( 1 ) delivery of large , shipped with a wide , should be selected with a higher speed .

    ( 2 ) long horizontal conveyor , should be selected with a higher speed ; conveyor inclination larger, shorter delivery intervals , the belt speed should be lower .

    ( 3 ) the material is easy to roll , large size , Flat belt conveyor strong abrasive , or simply dust as well as higher demand for sanitation , should use the lower belt speed .

Belt speed and the angle of the line Elevator conveyor bandwidth to transport , material properties , fragmentation and related conveyor when the conveyor transporting up big dip belt speed

should be low ; when the next operation, the belt speed should lower ; horizontal transport , the high belt speed can be selected . taking into account the level of

transportation, short length , the demand for belt speed

Is 2m / s.

Check the location of the material on the conveyor belt

A conveyor belt of deviation and its treatment

Deviation conveyor belt conveyor running is one of the most common faults . There are many reasons for deviation , the main reason is to install low precision and routine

maintenance is poor.

During installation , between the head rubber belt conveyor and tail rollers , the intermediate roller on the same center line as possible , parallel to each other and to ensure that the belt is not

biased or less biased. In addition, the strap connector to the right, should be the same on both sides of the perimeter .

During use , if there is deviation , they have to make the following checks to determine the cause , be adjusted. Incline Belt conveyor Conveyor deviation always check the location and processing

methods are:

1, check the rollers do not coincide with the center line of the transverse conveyor longitudinal centerline . If the values ​​do not coincide more than 3mm, you should take

advantage of the elongated mounting holes on both sides of idlers be adjusted . The specific method is biased on which side of the conveyor belt , which the lateral conveyor

idlers forward

Forward direction or another after the side shift.

2, check the head , tail rack-mounted bearing deviation of two planes values. If the deviation is greater than two planes 1mm, the adjusted response to the two planes in the

same plane. Adjustment of the head drum is : If the conveyor roller deviation to the right , then the right side of the roller bearing should move forward

After moving or left bearing shift ; If the conveyor roller deviation to the left , the left side of the roller bearing should move forward or to the right bearing after shift.

Rear roller adjustment method and the head drum opposite.

3, check the position of the material on the conveyor belt . Material is not centered on the conveyor cross-section , will lead to the conveyor belt deviation. If the material

is biased to the right, then the belt deviation to the left , and vice versa. In should be used as much as possible so that the material in the middle. To reduce or avoid such

conveyor run

Partial increase the blocking plate , change direction and position of the material.

When food is pulled off the conveyor belt conveyor

Tilt grain conveyor , when the belt is pulled off due to an accident , the belt material , and to produce it at the decline clogging . To prevent pulling up the rear of the

conveyor decline required to set traps for broken belt protection. Role trap is broken belt , the automatic action to seize the conveyor belt

The conveyor belt to stop. It therefore requires portable conveyor quick response, there is as small as possible braking time and braking distance. In normal operation the belt conveyor belt is

not worn , no additional resistance , Plastic belt conveyor without reducing the productivity of the conveyor . Material filled extent and reliability of its work without the belt

Conveyor installation angle impact . Trap can be used , such as a wedge and wheel stop mode .

1 ) It is a wedge-shaped trap consists of two rollers mounted on brackets , guide ramps , locking mechanism and glide board composed . When pulled off the conveyor belt ,

detected by the speed sensor , and to disengage the locking device , slide the bracket down the conveyor belt was caught between the wedge and skateboards

. Completion of the conveyor belt arresting work .

2 ) It consists of upper and lower rollers catcher wheel brake , limit switches , spring preload and compression pulley components. The upper and lower sides of the belt brake

wheel grip , which can be rotated about its axis relative to the conveyor belt for rotation without sliding . When broken belt , the conveyor and material gravity is run by

upward

Into sliding down due to the brake drum rotates in only one direction can not be rotated in reverse direction , the brake wheel and the belt slip , slide under the action of

friction , to rotate with the wheel brake lever , two wheel brake soon the conveyor belt grip , played the role of conveyor arrest . In braking delivery

With the same limit switch signals .

Food matching bandwidth conveyor

Food conveyor belt speed transmission capacity and bandwidth proportional , with conveyor belt width, thickness increased, the deviation has been reduced, with a high -speed

desirable values ​​.

 Increase the belt speed , belt conveyor can transport belt conveyor design in the same capacity with a smaller bandwidth conditions , while reducing the load conveyor line , the tension decreases,

the strength of belt conveyor manufacturer lower prices cheaper conveyor can be used. Belt speed is increased, the size and mass of the drive means are correspondingly reduced . Therefore

Improve with speed , reduce the bandwidth of great economic significance. However, with the increase in speed may be raised dust transport , causing material damage to be

shipped , but also in the loading section , cleaning section , etc. to increase belt wear.

Impurities adsorbed grain conveyor magnet surface regularly cleaned by hand

Separation of magnetic impurities can be installed as a permanent magnet device in food processing machinery, feed chute , the food conveyor magnet surface impurities adsorbed

by artificial cleaned regularly. May also be a permanent magnet or an electromagnetic drum roller , i.e., a belt conveyor manufacturer non-magnetic roller built in a fixed semi-cylindrical permanent

Long magnet or electromagnetic steel , grain export flows along the surface of the roller , magnetic impurities are adsorbed on the surface of the drum magnet , and with no

magnet drum rotates to the area from falling into the collection container. Separation of colored particles of food ( such as wheat black horn wheat, rice red rice , yellow

Brown rice, etc. ) available portable conveyor optical sorting machine . Each slot machine in the parallel installation of photoelectric sensors, food was fine stream flows through the thin,

narrow slots . When the colored particles flowing through the light zone , its reflective properties procure sensor sends information, and then open the shutter slot at the

bottom of the colored particles discharged

Tablets. This equipment is good, but the production rate. Of rice or brown rice has Mans barnyard barnyard grass can be electrostatic machine, food was uniformly thin layer into

the machine , there are tares due to the polarization properties of mango in a strong electrostatic field significantly biased side of the machine to be ranked outside the

machine .

Separated by flow characteristics using food particles and impurities suspended in the airflow velocity size separation . Fan belt hand cars and winnowing machines are winnowing

the application of this principle when artificial . Winnowing machine cycle can be used to clear the food shown in the light impurities . Food and feed through the hopper

Air flow evenly into the roll , drop to the bottom by a screw conveyor discharge machine , the impurities were carried by the suction duct airflow into the dust chamber ,

settling in the end portion of the rear by another screw conveyor from the plane , the air back into the blower continue recycling
