Conveyor History




Conveyor (Conveyor)
Conveyor line in a certain material handling machinery continuous feed of material, also known as the continuous conveyor. Conveyor can be horizontal, inclined
Conveyor - Shanghai Dongyuping machinery to provide
And the vertical conveyor can also be composed space transmission lines, transmission lines are generally fixed. Conveyor conveying capacity, long distance, but also in the

transportation process while completing a number of process operations, so widely used.
Can be a single conveyor can also be composed of multiple components or other transportation equipment horizontal or inclined conveyor system to meet the different needs of the

operating line layout.
Conveyor according to mode of operation can be divided into: 1: Conveyor 2: screw conveyor 3: bucket elevator
The main parameters of the conveyor
Generally based on the requirements of material handling systems, material handling location of a variety of conditions, the production process and material characteristics to

determine the main parameters.
① Transmission capacity: conveyor transport capacity per unit time is the amount of material transported. In transport bulk materials, transportation of materials per hour mass

or volume calculations; during transportation into items, the number of pieces per hour transport calculations.
② Conveyor speed: increase transmission speed can increase transmission capacity. In order to make the traction belt conveyor length pieces and large, the conveying speed

increasing day by day. But high-speed operation of the belt should pay attention to vibration, noise, and start braking and other issues. For chains as traction

Parts conveyor, conveyor speed should not be too large to prevent increased dynamic loads. Simultaneous process operation conveyors, conveyor speed production process

requirements should be determined.portable conveyor
③ component size: scantling including conveyor belt width, belt width, hopper volume, pipe diameter and vessel size. These have a direct impact scantlings conveyor conveying

capacity.
④ transport length and angle: transfer line length and inclination of the conveyor directly affect the size of the total resistance and the power required.
Conveyor features
Variable direction, the flexibility to change the conveying direction, the maximum can be up to 180 degrees;
Conveyors, each unit consists of eight rollers, each one unit can be used independently, multiple units can also be connected to use, easy to install;
Retractable conveyor, a unit ratio of the longest and shortest state can reach three times;
Flexibility to change the conveyor conveying direction, the maximum may be greater than 180 °

Rubber conveyor belt in square units of measurement, custom, the length and number of square meters should also be raised.
Tape Specifications Length Representation
Bandwidth (mm) x fabric layers [glue thickness (mm) + down thick plastic (mm)] x belt length (m)
Tape square conversion method can be used:
Number of square meters = Tape Width (m) x [cloth layers + (glue thickness (mm) + down thick plastic (mm)) / 1.5] x length (m)
Conveyor History:
Chinese ancient high drum water overturned cars and mentioning, is the modern scraper bucket elevators and conveyors prototype; 17th century, began to use aircraft
Empty cableway transport bulk materials; 19th century, various modern structures conveyor has emerged.
1868, in the UK there has been belt; 1887, in the United States appeared screw conveyor; 1905, appeared in Switzerland steel belt conveyor; 1906, in the United Kingdom and

Germany appeared inertia conveyor. Thereafter, conveyors manufactured by mechanical, electrical, chemicalFlat belt conveyor

And metallurgical industries impact of technological advances, and constantly improve gradually from inside to complete the delivery of the workshop, the development completed

within the enterprise, between enterprises and even between cities material handling, mechanized and automated material handling systems become an indispensable component.
Classification of the conveyor
Conveyor according to whether the pulling elements generally be classified
A conveyor having a traction member generally include traction, bearing components, drive means, tensioning means for redirecting means and the support parts. Tractor parts used

to pass traction, can be used conveyor, drag chain or rope; Holds material bearing member to have the hopper, bracket, or

Spreader, etc.; drive to the conveyor to power, generally consists of motor, reducer and brake (stopper) and other components; tensioning devices generally have two kinds of

screw and a hammer, can maintain a certain tension pulling element and sag in order to ensure the normal operation of the conveyor; support for Order

Traction prop pieces or carrying member, can be idlers, rollers, etc.
A conveyor having a traction member structure is characterized by: the material to be transported to the traction member mounted on the bearing member are joined together, or in

directly mounted on the pulling element (such as belt), the pulling element or chain around both of the rollers connected to form load transportation of materials, including

branches and not transported

The material being a non load branch closed loop, continuous motion using the traction member conveying materials.
Such a wide range of conveyors, the main belt conveyors, slat conveyors, trolley conveyors, escalators, moving walkways, scraper conveyor, buried scraper conveyor, bucket

conveyor, bucket elevator , overhead conveyors and overhead lifts and so on.
Conveyor without pulling element different structure and composition, working member for transporting the material is not the same. Their structure is characterized by: the use

of rotational movement of the work member or reciprocating motion, or by the medium flowing in a pipe conveying the material forward. For example, the roller

Conveyor working member of a series of rollers, the roller rotates to transport materials; screw conveyor working member of the spiral, spiral chute rotates in order to push the

material along the trough; vibrating conveyor working member of material groove, trough placed reciprocated to convey

One of the materials.
Conveyor will be toward the future large-scale development, to expand the scope, automatic sorting of materials, reduce energy consumption, reduce pollution and other aspects of

development.
Large transmission capacity, including large-scale, large single length and large transmission angle and other aspects. The length of the hydraulic conveyor belt has reached

more than 440 km length of nearly 15 km of single, and has appeared composed by a number of Taiwan Contact B two places "belt conveyor path." Not

Few countries are exploring long-distance, large capacity continuous transport of materials better conveyor structure. Expand the use of the conveyor, is developing in high

temperature, low temperature conditions, corrosive, radioactive, flammable substances in the work environment, as well as capable of delivering fiery, explosive

, Easy to agglomerate viscous material conveyor
Development trend towards the development of the conveyor are: ① continue to large-scale development. Large transmission capacity, including large-scale, large single length

and large transmission angle and other aspects. Hydraulic conveyor length reached 440 km or more. Belt conveyor length of nearly 15 km single,

And has appeared composed by a number of Taiwan Contact B two places "belt conveyor path." Many countries are exploring long-distance, large-capacity transport of materials

better continuous conveyor structure. ② to expand the use of the conveyor. Developments in high temperature, low temperature, corrosive, radioactive

Sex, flammable substances in the work environment, as well as capable of delivering fiery, explosive, Pellet, sticky material conveyor. ③ the conveyor structure to meet the

automated material handling system to control stand-alone asked for. As used in automated sorting post office parcel trolley conveyor

Sorting machine should be able to meet the requirements of such action. ④ reduce energy consumption in order to save energy, the field of conveyor technology has become an

important aspect of research. Has one ton material handling energy consumed by one kilometer conveyor selection as one important indicator. ⑤ reduce all kinds of conveyors

Generated during operation of dust, noise and emissions.
