With the rapid development of economy, the rapid production of enterprises is inseparable from the automatic conveying system. In the composition of automatic conveying system, conveyor application is the material handling system mechanization and automation, an indispensable part.
The history of conveyor is very long, if you want to pursue the development of conveyor, the earliest can be traced to ancient China's high drum and water overturned car. These two use principle, and the design principle of modern conveyor is very similar, can be said to be the prototype of the development of modern conveyor.
Development course and present situation of conveyor
In foreign history, Archimedes, the Ancient Greek philosopher, invented a spiral water pump, using the continuous rotation of the screw, the use of liquid spiral pressure from a sealed chamber to another sealed chamber, and finally extrusion pump body. This kind of screw pump is the prototype of screw conveyor today.
In the past 30 years, with the development of industrial technology, social productivity and labor costs, the requirements for work efficiency are constantly improving. Delivery, logistics, factories, warehouses and other places in labor-intensive industries have a new pursuit of staff efficiency.
Naturally, in which the most used conveyor, transport equipment has made great progress. Now, the direction of conveyor development can be roughly divided into the following types:
1, turn conveyor: suitable for all kinds of production plants, small and medium-sized goods logistics, power system adopts frequency control system, stable performance, safe and reliable, simple operation, linear speed is generally in 30 meters per minute.
2, climbing belt conveyor: the use of continuous or intermittent movement of the conveyor belt, conveying items below 500kg, or powder, granular items. Climbing belt conveyor is used in high and low difference, can complete continuous transmission, smooth and roller conveyor, or chain plate conveyor connection.
Development course and present situation of conveyor
3. Narrow belt conveyor: it is mainly composed of two end rollers and a closed conveyor belt, which is driven by the friction between the roller and the conveyor belt. In addition to pure material handling, it can also be matched with various industrial production processes to handle requests, forming a rhythmic streamlined traffic line.
4, telescopic belt conveyor: telescopic belt conveyor is in the ordinary belt conveyor to increase the telescopic mechanism, making the belt machine can be free in the direction of length, telescopic belt machine can be two-way operation conveying materials, reduce the cost of loading and unloading, improve work efficiency.
Now because the global environmental pollution is more serious, domestic energy conservation and emission reduction policies are put forward to ensure the survival and living environment of Our country. Nature of environmental protection requirements for all walks of life, there is a new round of promotion. Therefore, it is predicted that the conveyor industry will develop in the following directions according to the national policy and strategy:
1. Conveyor continues to develop to large scale.
Large scale includes large conveying capacity, large single machine length and large conveying Angle. The length of hydraulic conveyors has reached more than 440 kilometers.
At present, the length of the single belt conveyor has been nearly 15 kilometers, and has appeared by a number of components of the connection between a and B "belt conveyor". Many countries are exploring a more perfect conveyor structure for conveying materials continuously for long distance and large volume.
Development course and present situation of conveyor
2, expand the scope of use of conveyor.
To develop conveyors that can work under high temperature and low temperature conditions, corrosive, radioactive and inflammable materials, and transport hot, explosive, easy to agglutinative and viscous materials.
3, make the structure of the conveyor to meet the requirements of the automatic control of the material handling system for single machine.
For example: the post office used automatic parcel sorting trolley conveyor should be able to meet the requirements of sorting action.
4, reduce the energy consumption of conveyor to save energy, has become an important aspect of scientific research in the field of transportation technology. The energy consumed to transport 1 ton of material for 1 km is taken as one of the important indicators of conveyor selection.
5, reduce the dust, noise and exhaust gas generated by all kinds of conveyor in operation.
Conveyer prospect is immeasurable, the output value of this industry, will reach a new height. Because the conveyor conveying, not only simple goods and equipment, but also to promote the power of social development, is also the footprint of human civilization and future development direction.

Redirection roller - as are used with conveyor belt and conveyor, the use of the product in the concrete of beautiful shape, apply more extensive, can be used in ah cesspool, wet, muddy conditions such as evil slightly, the drum is often used, so what exactly is the purpose of his, to detail below.

The function of the drum is to change the winding direction of the tape, so that the tape forms a circular closed component. The general form of his performance is: the tail roller of the conveyor, can produce 180° of direction; The tensioning roller comprising the tensioning device; Increase the roller of the belt wrapping Angle, so that the belt has a certain direction. There are also two kinds of switch to the roller and no rubber package. The steering drum, also known as the leading steering drum, is a common belt mechanical accessory. It is mainly used in changing the running direction of the conveyor belt or pressing the conveyor belt to increase it and drive the drum. It is the driving device of various mobile belt belt machines and can also be used by some fixed belt belt machines.

The driving drum is the core output of power in conveying equipment, or the transmission unit, which can be mainly used to transport the conveyor belt and materials, provide power for use, and increase the Angle between the driving drum and the conveyor belt, so as to improve the working efficiency of the driving drum.

In general is mainly used to change the running direction of conveyor belt, or enlarged its compaction conveyor belt and transmission Angle of roller, guide roller is mainly at the bottom of the belt movement, such as belt transporting direction to the left, then the redirection roller on the right side of the belt conveyor, the main structure for bearings and steel cylinder, transmission roller belt conveyor is driving wheel.
There are many functions of changing the roller. On the one hand, it can change the direction of transportation and on the other hand, it can provide work efficiency. These two points are introduced in the above article.

Sep .26.2022
There are many kinds of conveyor belt, and there are many kinds of colors. The conveyor belt has a wide range of applications, and because the color will be liked by more users, but the conveyor belt will easily become dirty, and it needs to be cleaned frequently. Then how should the conveyor belt be cleaned more routinely?

The production workshop of the conveyor belt needs to go through a series of cleaning work before production. Some plastic paper and other things will be spread on the ground of the workshop to prevent the conveyor belt from being stained with dust or other dirty things.

But in the process of production, there is still some dust or any other waste debris. If you get it, how do you clean it up?

In general, it can be wiped clean with a wet rag. If you encounter some places that can't be wiped off, you need to use some chemicals to wipe. No melted rubber can be dissolved in benzene, can use cotton or towel dipped in benzene to wipe, must pay attention to: benzene is flammable, is also easy to volatilize, when using must pay attention to safety, do not close to the open flame.

After the conveyor belt is wiped with benzene, the conveyor belt will be clean again, very beautiful.
How to avoid the rubber surface damage of bucket elevator conveyor belt How to avoid the rubber surface damage of bucket elevator conveyor belt
Sep .26.2022
Bucket elevator conveyor belt in the process of use often appear glue surface damage, glue surface damage after the conveyor belt there is no way to use normally, and even affect the service life of the conveyor belt, how should we avoid bucket elevator conveyor belt glue surface damage?

1. Reduce the large impact on the conveyor belt

The drop design of the transportation system is relatively large, the direction of coal flow is unreasonable, there are many large pieces of material in the material, it is possible to cause impact on the conveyor belt in the process of transportation, the surface of the conveyor belt of the bucket elevator produces a lot of pits, so that the rubber surface of the conveyor belt damage.

2. Do not touch high temperature materials

When the slag and coal of the boiler room are transported by the conveyor belt, the slag and coal without cooling will melt the covering glue on the surface of the conveyor belt and aggravate the abnormal wear on the surface of the conveyor belt. The sparks generated by electric welding and gas cutting will also have an impact on the glue surface of the conveyor belt.

3 bucket elevator conveyor belt quality

In the process of making the conveyor belt, the adhesive force of the adhesive material is not enough, the process is defective or a certain process is not strict. Under the reaction force of friction force, the covering glue is gradually peeled off on the conveyor belt, and there may be tearing when it is serious.

In a word, in order to reduce the phenomenon of damage to the rubber surface of the conveyor belt of bucket elevator, special attention is needed in production and use, and the conveyor belt of good quality should be purchased when buying, and the regular manufacturer should be purchased as far as possible. In the process of use, pay attention to the use of details, to ensure the standard operation.
