Dynamic characteristics of the conveyor belt

Also called transport conveyor belt, conveyor belt is made of rubber and fabric core or rope core composition. Since the rubber itself is rheological material , coupled with

anisotropic fabric core or very complex heavy duty conveyor situation by force steel cord , which has a very complex dynamics , the deformation and

Load size , history, time, frequency , ambient temperature , material properties and other factors , the main manifestations are:
1 the stress -strain relationship is nonlinear characteristics , dynamic modulus of elasticity is not a fixed value.
2 for a hysteresis characteristic is that when loading and unloading cycle, the strain does not immediately uninstall with loads return to its original position, during which

time history is to have a
Creep Characteristics When sleep Airport conveyor 3 is loaded , the holding load constant elongation of the belt to increase with time , when after a certain time reaches a stable value
4 relaxation characteristics when loaded to maintain constant elongation suffered payload size gradually decreases with time , after a certain time has reached a stable value
5 the frequency characteristic and also the amount of deformation belt loading frequency size.
In industrial production , the correct use of conveyor belt is particularly important , the conveyor belt in the use of the main note the following:
1 to avoid roller covered by material , causing rotation ineffective to prevent leakage of material card in between the tape and the roller , pay attention to the lubrication of

conveyor belt moving parts , but not oil belt ; 2 must prevent belt load start , or will cause serious consequences ;
3 conveyor deviation occurred , to immediately take measures to rectify ;
4 found conveyor local damage , the application of rayon timely repair to avoid expanding , such as not ask professionals ;
5 to avoid being conveyor rack , pillars or massive block of material , to prevent misfortune to scratch the rip .

Chain conveyor types and characteristics

Chain conveyors are two major categories for the chain conveyor and the conveyor, that these two types of Conveyor System What are the main features , and is now a brief introduction

:
( 1 ) chain conveyor
Applications: Mainly used parts warehouse or inland ports .
Advantages: able to withstand put on plate heavier pieces of cargo , chain flexibility , and high strength .
Disadvantages: weight , wear and tear , power consumption than the big belt .
( 2 ) scraper conveyor
Applications: can be used for horizontal, inclined and vertical conveying bulk materials , commonly used in grain, feed mills grain , semi-finished and finished products

transportation , especially for Heat Exchanger fuel oil processing plant in the production process of transport and delivery of food grain warehouses .
Advantages: simple structure , good sealing, discharging device into a simple, multi-point into the discharge, arrangement of flexible, multi-directional simultaneously

completed the delivery of materials .
Disadvantages: trough easy to wear, especially in the chain badly worn .
Complete understanding of the chain conveyor , let's look at another conveyor - chain conveyor , and analyze it and other intermittent transport machinery , compared with what

are the advantages .
Chain Conveyor as a good performance of the continuous conveyor can be within a certain range , in accordance with the technical requirements of material transport from the

initial expect the final discharge for the formation of stable materials transportation process , so that the chain conveyor machine transport materials and other intermittent

operation

Compared to the transport machinery has the following advantages:
( 1 ) can be kept in the same direction as the transport of materials , loading and unloading without stopping , can be transported at high speed , and thus have high

productivity.
( 2) Since the chain conveyor and running speed for feeding a uniform stable, the power consumption of the process is not changed , and thus , the drive power is small .
( 3 ) the maximum load chain conveyor difference is small , and thus the design calculations small loads.
Therefore, the chain conveyor and material handling machinery in numerous plays an increasingly important role . And, in a variety of modern industrial enterprises , chain

conveyor transports the material was not simply that it has become the industrial production process as an integral unit .

Products of the film in the special requirements of the roller

The calendering and extrusion processes, typically occurs under a lot of roller compaction force, the relative products, a certain separation force, if supported on the roller

bearings on both ends of the cylindrical Incline Belt conveyor beam, and therefore can not use normal beam theoretical formula to calculate the bending deformation, but with the deflection value (

Including bending deflection and shear deflection) seeking the formula for maximum deformation. That in the actual production, the total deflection of the central roller is much

larger than the allowed tolerances products, must try to compensate, or fail to achieve the required precision products. Since the roll deflection in the central part,

Both ends of the small, so products appear thicker in the middle, both ends of the thin, hence crowning There are Weight Sorter typically three ways, namely height method, the pre-load method

and pre-load device.
To eliminate the thickness of both sides of the thin intermediate products case consciously work roll surface processing into the central diameter, a small diameter drum-shaped

ends, wherein the maximum diameter and the end portion of the minimum diameter difference is called the height E. Of course, the ideal shape of the curve should be highly

rollers

Deflection curve. However, due to machining difficult to do, is often used as part of an arc or ellipse approximation to compensate.
In fact, highly accurate curve is not necessary, because the impact of the size of the cross-pressures many factors, these factors change, horizontal pressure changes, the

deflection will change accordingly, so the fixed height compensation law in the limitations large, generally not used alone. By the

At the height compensation method is simple, more general use. When the roller when no other compensation method with which the height of 0.02 ~ 0.10mm range, used in

conjunction with other compensation method when the height of 0.02 ~ 0.06mm range. The general manufacturers in the production of high, pass

Over the grinder grinding pull at an angle in high demand from both ends toward the middle ground, this operation tends to form a horn, both sides are straight, no high curve.

And some companies are currently using large CNC roll grinding, then the use of the computer for automatic control console

Curvilinear motion, so grind the roll surface is a curved shape, is basically consistent with the deflection curve, plastic products to meet the requirements.
Strict implementation of the roller production process to ensure the quality of the roller
Currently, the country has a lot of roller manufacturers, but can really provide high-quality roller few manufacturers. The reason is to do a high-quality roll manufacturing

process must be strictly enforced, the lack of any one intermediate step, the surface can make a roll, but in reality

It reveals the process of using the occasion of serious quality problems that affect the normal use of factory production.
Therefore, to make a high-quality roll roll blank first strict selection of materials, plastics should be different in the selection process seamless or centrifugal casting or

forging parts, in the production process, to be used for different roll blank corresponding The quenching and tempering heat treatment processes; its

Times, in the processing process, after the welding process must also eliminate stress, to improve the surface hardness of the surface hardening or nitriding processes, must not

be deprived because of the high costs of these processes, which appear on the surface can not see out, but in the actual use of the production process

There is a serious risk, which is absolutely not allowed to roll production. Further, in electroplating and surface treatment process should strictly ensure moderate coating

thickness, especially during grinding process in the ultra-fine grinding process steps should be carried out strictly in accordance with, should never be neglected figure

Province chart fast normal

Steps to reduce the process, otherwise no legal qualified to the roller.

Process should be to select a different type of roll

Especially the mirror roll roller for plastic packaging industry is not prepared an indispensable part, whether it is rolling, extrusion molding or casting rolls are

inseparable. Production quality precision roller surface and internal flow channel structure is reasonable and precision is good or bad, will

Direct impact on the quality of plastic products, vertical conveyor especially for plastic film is even more so. Thus providing a high quality plastic sheet membrane for roll products

manufacturers particularly important.
A wide variety of rolls, and has its own unique role, according to a process of rolling stick, pressure bachelor, casting rolls, etc., according to functional use of a heating

roller, cooling roller, away Mine conveyors from the roller, roller, etc., according to Structure of a seamless roll, forging and centrifugal casting roll. In summary,

Plastic products, different processes require different roller, therefore, as a roller manufacturers to undertake the process of making the roller should be for different

products, different design and manufacturing process corresponding roller, the roller in order to ensure that the production process play its normal role.
Regardless of process methods, the roller structure, design, material selection and processing should comply with the following several basic requirements:
1. Roll should have sufficient rigidity to ensure the heavy load, the bending deformation does not exceed the allowable value.
2. Roller surface should be of sufficient hardness, generally required to reach HRC50 degrees, with strong corrosion resistance. Coating with anti-spalling capacity to ensure

that the work roll surface has good wear resistance and corrosion resistance.
3. Work roll surface should be fine processing, in order to ensure dimensional accuracy and surface roughness. Roughness should Ra0.16 above, can not have holes or grooves.

Roller working surface thickness should be uniform, otherwise it would roll surface temperature uniformity, affecting the quality of products.
4. Roller material should have good thermal conductivity, usually chilled cast iron, cast steel or special circumstances chrome molybdenum alloy steel, either heating or

cooling, can achieve rapid and uniform.
5. Roller designed to facilitate processing, low cost.

Roller conveyors run method
