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.

Hanging chain industry characteristics highlight for enterprises to improve efficiency

chain is hanging conveyor for short.

Suspension chain conveyor used to go round as a ball bearing, idler pulley are made of 16Mn material after deep processing. Is able to turn, climb, can adapt to a variety of

geographical and environmental conditions. The transmission line is mainly used in the workshop of the material on the air distribution, chain pitch commonly used 150,200

, 206,240,250,300 (mm), etc.. The main structure made of carbon steel production.

Hanging conveyor can freely choose transmission lines, and can effectively use space saving manpower ﹑ ﹑ improve work efficiency, mainly by rail chain ﹑ ﹑ ﹑ spreader, stand

seat and adjust the seat and other gear components. VVVF control system. Widely used in parts of the far

Distance transportation, upgrading floors, air storage, feeding and other processes and automated paint production line.
Hanging conveyor for factory paint, metal coating, assembly line production, such as furniture factory, bicycle factory, electronics factory, electroplating factory, hardware

factory, leather products factory, automobile factory.
Hanging chain line body length: Max 300m, more than 300 power plants need two.
Hanging chain line height: Variable, chosen by the customer.
Suspension chain conveyor speed: variable speed, variable speed.
Hanging chain load: Chain pitch is 150mm, load weight 8kg; Chain pitch of 200mm, load weight 30kg; Chain pitch of 300mm, load weight 60kg.

Hanging chain is a three-dimensional closed-loop continuous heavy duty conveyor for an internal workshop and workshop items into between the automated conveyor. The method according

to transport objects can be divided into general and lightweight traction hanging conveyor, general product release type and light product release type of push hanging conveyor.

Hanging chain, as the chain to go round with ball bearings, rails are made of 16Mn material after deep processing, the useful life of five years. Chain pitch commonly used

150/200/240/250 etc., single point load also varies. At the same time by selecting the type of spreader, increase the chain

Single point load. The transmission line is able to turn, climb, can adapt to a variety of geographical and environmental conditions. The transmission line is mainly used in the

workshop air distribution on the material, design reasonable solution, can warehouses, assembly lines and other related organic combination of nodes can be rationalized to the

greatest extent

Workshop logistics, resulting in greater efficiency. The conveyor line can also be used as a motorcycle frame unit installed, as well as spray drying equipment, transportation

equipment.

Deceleration conveyor means

You can use squirrel cage induction motor: This type of small motors, portable conveyor mechanical variable speed drives can be like the Department of Space is not the speed, the drive

may be small, light weight form; if reconnected gear (gear), then the multiplier effect. No brushes or commutator, so almost no

Requiring maintenance basis.
Can only be set in both circuit design, the speed of the motor can be inserted into gear transport, transformation to become infinitely variable.
In order to improve performance: speed control range, is (soft start stop) to adjust the set time is really smooth and soft to change speed, you can ensure that the entire smug,

helpful product safety, ensure quality.
Often able to play a role:
Low-frequency and voltage gear domain ID slowly rising frequency and voltage value, the start of direct commercial power and a good starting efficiency, from small and large

starting torque resulting current. Small heat motor result is that there are more frequent starting, stopping and harmless
 Bay forward or reverse gear control transistor switches from the phase rotation. This way than the previous phase main circuit wires through the switch means movable parts and

is not part of the friction, heat will be more effective, so you can come back to the horizontal (lateral) as the forward reverse

Transportation frequently enables remote command will be able to change the frequency to do so. Therefore, it is easy to select the most suitable working speed to the right to

use.
Electrical braking deceleration, the motor will slow down the supply, the output frequency, motor speed will exceed the sync speed situation. When this state, the resistor is

not used, the motor still has 20% of the braking force of the degree of internal loss. Typically Turn conveyor constant torque load, it was quickly

Slow down, if not necessary, because there is no need to set any occasion most of the braking resistor. Braking frequency, particularly if the vector control using the low speed

mode, the speed control can be achieved with PG range 1:100 1:1000 'S as an alternative of the speed control operation.
Start and stop obedience: As speed, transmission speed, the material will be sent by the collapse of the conveyor, such as glass suddenly stops moving, then touching and glass

bottles, which may damage; but if the operation of the gear, as it is A low frequency start, so a small earthquake

Move, and the soft control.
