How to improve the roller conveyor stand-alone function

   Roller conveyors in recent years the development of industrial production and the traditional manual manipulation into automated production control production, greatly

improved production efficiency . Enterprises industrial output increased significantly, to provide the market with enough goods to make people's living standards have

Greatly improved . But this does not mean omnipotent Telescopic conveyor , roller conveyors blindly admired the function and role would be detrimental to the development roller

conveyors and various industries.
   Roller conveyor manufacturing companies in China has been recognized by everyone . But blindly produce the same kind of roller conveyor roller conveyor market opportunities

resulting stagnant. In order to meet the needs of enterprises more productive , not only increases the production of Extendable conveyor , it is also

Continuous research and development of new products, including accessories such as roller conveyor drive roller , Feet and sprockets . Looking around on the market most of the

roller conveyor roller conveyor is similar, although a variety of stand-alone functions roller conveyors , there was significant difference

However , stand-alone functionality roller conveyor as a constraint to the lack of roller conveyors development bottleneck.

Belt conveyors and conveyor belt safety practices

Belt conveyor structure forms, climbing flexible conveyor, belt conveyor roll with Groove belt conveyor, flat belt conveyor, belt curves and other forms. Also called conveyor belt

conveyor or belt conveyor is composed of non- pipeline operations and orderly economic deficient

Conveying equipment .
A Flexible skatewheel conveyor safety practices :
Before the operation must be properly worn labor protection.
Before starting to conduct a comprehensive inspection of the equipment , remove obstacles , good start preparatory work , make sure the belt and tail wheel parts unmanned before

boot .
Checks before start switch cards in good condition , the first for no-load operation , not free unlocked . Must be confirmed before starting the scene .
After the shutdown , the belt must be vented state , try to avoid stopping and starting with a load .
Equipment operation, should always check the motor, reducer , both wheels, cleaning, drain on materials , inspection equipment lubrication , gear or electric drum sound is

normal , functioning in various parts of the temperature must not exceed the specified value .
Belt does not start up or slip, is strictly prohibited to use pedals, chain and other ways to deal with , equipment operation site in the operation , the non- cleaning, touch

operation site, are not allowed to sit in the shade on the belt , rest, chat .

Belt conveyor of knowledge you ask me to answer

1 , What are the shortcomings of belt ?
Covering large ; big investment ; overhaul inconvenience , you need to loosen the belt , the operating volume.
2 , the main shaft Pallet conveyor belt is the lack of strong mean ?
Long distance, steep slope . Optional belt ; pull and progression is not enough.
3 , belt conveyor belt deviation how to solve ?
Blanking point is not correct, or blanking uneven. When the load is very positive, the question should be is feeding .
4 , belt wearing parts What ?
Belt wearing parts are , guide bar , block of coal strip , coal hopper baffle , roller and stopper .
5 , there are several reversible Food conveyor electric drum ?
A . Can not use the two are not with the same speed , the same model on ok, belt slippage choose plastic drum kits , increasing friction.
6 , has been known belt length, speed , roller diameter , motor power, angle, how election gear ?
Drum diameter and velocity is calculated according to the drum speed to determine ratio , according to the motor power factor multiplied by the use of mechanical power to

determine the gearhead , and then according to the mechanical power and the gear ratio to determine the base, this will look from the sample the corresponding on it.

Compared with foreign countries the lack of fire-retardant conveyor belt

One, carrying capacity is poor, life is short. Of PVC, PVG flame retardant conveyor belt carrying capacity and life of most less developed countries to use the largest 1000S retardant Elevator conveyor, for example, the domestic life of the tape is generally not more than two years, the amount does not exceed the cumulative coal

More than 200 million tons, while the useful life of similar products abroad more than 4 years, the cumulative amount of more than 6 million tons coal.

Second, the lack of core technology, independent innovation ability is poor. Our PVC, PVG whole flame retardant fabric vertical conveyor manufacturers, mostly small and medium enterprises, and foreign produce PVC, PVG flame retardant conveyor belt manufacturers and more for the world famous enterprises, with strong core technology and independent

Innovation in the manufacture of the product while creating products, while most domestic companies manufacture products not only to create products.

Third, the process equipment and production technology level is not high, the lower grade of products. Domestic enterprises, flame-retardant PVC conveyor belt production technology is more mature, but PVG retardant conveyor belt production technology level is still low. The first is relatively backward and complex production processes, energy consumption,

Low productivity, and because the band body through the second plasticizing strength severely decreased. The most advanced production technology is the use of an extruder veneer molding process, eliminating the traditional production process of mixing, shaping, vulcanizing and other processes to achieve with a core leaching paste, plastic, covered

Cover stickers, vulcanized continuous production, the production efficiency greatly improved. At present, China's production of the highest strength grade PVC, PVG flame retardant conveyor is 2500N/mm, a maximum width of 2000mm, while foreign produce strength 4000N/mm, of a width exceeding 3500mm

Whole flame retardant fabric conveyor belt.

Conveyor generally without pulling elements to 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

hammer, pulling elements can maintain a certain degree of tension and vertical in order to ensure the normal operation of the conveyor; supporting member for supporting the

retractor

Cited documents 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 do not ship material

The no-load branch material, 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

Machine 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 the trough , reciprocated chute placed therein to convey

The materials.
