Description
Technical Field
The invention belongs to the technical field of mining machinery equipment, relates to a key component of a belt feeder, namely a conveyor belt, and particularly relates to a composite conveyor belt of the belt feeder and a manufacturing method thereof.
Background
In recent years, a belt feeder is popular on the market, is used as a feeding device of various bins, and is structurally characterized in that: a closed belt is arranged at the bottom of a lower guide chute of the storage bin, the belt at one end is driven by a driving roller, a turnabout roller is arranged at the other end, a plurality of groups of supporting rollers are arranged in the middle to support the belt, and a tensioning device is arranged on the driving roller or the turnabout roller; in order to obtain better service performance, a closed adhesive tape is arranged in the nail belt. Compared with the prior art, the technology has the following advantages: 1. the running power is small, the energy consumption is low, and the running economy is good; 2. the structure is light in weight, low in cost and convenient to transport; 3. the feeding amount is large and stable, and the adjustment is convenient; 4. the operation is stable, the noise is low, and the environment is protected; 5. the abrasion is small, the maintenance amount is small, and the service life is long; 6. the universality of parts is strong, and the installation and the maintenance are simple and convenient; 7. the existing feeder can be replaced, so the feeding device is widely popularized and used in the feed bin feeding industry.
The above mentioned belts and tapes are the main fittings in the transmission part of the belt feeder. The armor belt comprises a plurality of armor plates and a plurality of string strips, the armor plates are formed by precisely casting 16Mn or high-wear-resistance alloy steel and have good wear resistance and toughness, the string strips are made of nylon 1010, the string strips have good wear resistance and self-lubrication, the impact resistance of the armor belt is greatly improved, when the armor belt is severely impacted by materials, firstly, the impact force is diffused from an impact point to the periphery in the structural form of the armor belt, secondly, the lower adhesive tape deforms to absorb a certain impact load, and simultaneously, the residual impact load is transmitted to the buffer carrier roller and the buffer carrier roller seat for buffer absorption, so that the impact resistance of the armor belt feeder is well improved.
The most representative nail, please refer to the nail of the art described in the chinese utility model patent with the reference name "a novel nail and contain the nail of this nail", application number 200720131242.X, including preceding link and back link, preceding link department has the preceding mounting hole that the cluster that supplies to connect the place ahead nail passed, and back link department has the back mounting hole that the cluster that supplies to connect the back nail passed, and the nail openly just is located and is equipped with the transition portion of concave surface form between preceding link and the back link, and the transition portion is the expansion form from inside to outside. The nail connecting holes forming the nail belt are connected and assembled by a string. The feeding effect can be greatly improved by the nail with the concave part, and after the nail connecting holes forming the nail belt are connected and assembled by the flexible string strips, the service life of the nail belt is prolonged, the impact resistance of the nail belt is improved, and the normal operation of the feeder is guaranteed. The tape provides strength and also prevents material from falling through the gap.
Compared with the reciprocating feeder and the vibrating feeder which are used in the past, the first-belt feeder changes intermittent feeding into continuous feeding, so that the production capacity is greatly improved, large-scale popularization and use are achieved in mine enterprises in more than ten years, and great contribution is made to national production.
The belt feeder, then, also has some disadvantages.
1. The process of installing the nail belt is time-consuming and labor-consuming. The current mounting means is gomphosis each other the first nail piece on mounting platform, the hole is neat with the pore pair, leave about 2 millimeters clearance between the terminal surface in adjacent hole, in order to do benefit to each other and revolute, then use the pliers to press from both sides the position that the cluster strip is close to the end and make strength wear to the downthehole of nail piece, just use the hammer to strike the pliers when the resistance that meets is too big, when keeping close to the nail piece when keeping silent, remove the pliers, make keep silent and leave a little distance on the nail piece, strike the pliers again after pressing from both sides tightly, constantly repeat above action, until whole cluster strip penetrates in all nail pieces of transverse arrangement.
The installation intensity of labour of this kind of mode is very big, and efficiency is very low, and the pliers presss from both sides the crackle to the cluster easily, still breaks the cluster easily, if the cluster is broken inside, still need pull out the cluster and wear new cluster again, and work efficiency is lower, breaks the cluster and causes the waste.
2. The wear is relatively fast. The nail belt and the adhesive tape are two separate elements, the adhesive tape being wound between two rollers. The adhesive tape is an elastic body and is provided with a neutral layer, if the adhesive tape is a steel wire rope core adhesive tape, the layer where the center line of the steel wire rope core is located is the neutral layer, if the adhesive tape is a canvas core adhesive tape, the neutral layer is arranged inside the adhesive tape, and the specific position depends on the number of layers of the canvas core, the spacing arrangement condition among the layers, the elastic coefficient of each layer of canvas, and a plurality of factors of the elastic coefficients of the upper cover adhesive, the lower cover adhesive and the core adhesive. The neutral layer of the nail band is the layer where the center line of the string is located. The neutral layer mentioned above is an imaginary layer whose length does not change when rotating around the drum, and on the belt or tape, the layer distant from the center line of the drum is longer than the neutral layer, and the layer close to the center line of the drum is shorter than the neutral layer. In summary, the neutral layer of the tape is inside the tape and the neutral layer of the nail belt is inside the nail belt. The part wound on the roller is taken as a research object, the adhesive tape is wound on the roller, the first belt is wound on the adhesive tape, the radius of the neutral layer of the first belt is larger than that of the neutral layer of the adhesive tape, and the angular velocities of the first belt and the neutral layer are equal, so that the linear velocity of the neutral layer of the first belt is larger than that of the neutral layer of the adhesive tape. And then, a straight part between two rollers on the conveyor belt is taken as a research object, when no material exists in the guide chute, the belt A and the adhesive tape are clung together and translate simultaneously, the two belts are tensioned, the positive pressure between the belts is not large, the linear velocity of the belt A is greater than that of the adhesive tape, and the abrasion is not serious. However, when the material guide groove is filled with materials and the bin pressure of the bin is completely pressed on the first belt, the positive pressure of the first belt on the adhesive tape is very large, the lower part of the adhesive tape is supported by a plurality of groups of supporting rollers, sliding friction still occurs between the first belt and the adhesive tape when the first belt feeder operates, the friction force is very large, particularly, the abrasion of the adhesive tape is very fast, the average service life of the adhesive tape is two or three months, the adhesive tape needs to be frequently replaced, and the maintenance cost of the first belt feeder is increased.
3. The nail belt is troublesome to maintain. The armor belt and the adhesive tape are simultaneously tensioned when the armor belt feeder leaves a factory, the lengths of the armor belt and the adhesive tape are increased in the using process, the length of the armor belt is increased because of unilateral abrasion between the string strip and the nail connecting hole, and the armor belt is lengthened due to the fact that materials on one side of the string strip are lost. The tape becomes long because of partial permanent deformation due to long-time stretching, and the stretched length of the tape is the superposition of the permanent deformation and the elastic deformation.
However, the two belts are not lengthened synchronously, the speed of the lengthening of the armor belt is always high, the lengthening of the adhesive tape is slow, the distance between the driving roller and the bend roller needs to be adjusted and increased through the tensioning device, but the armor belt still is loose to some extent even if the adhesive tape is very tightly tensioned and is about to be broken, or the driving roller or the bend roller needs to be broken, the armor belt has to be detached to remove a row of armor plates and then is installed, the work of detaching the armor belt is very difficult, the abrasion positions of the matching surfaces of the string and the two adjacent armor plates are right opposite to each other from left to right, and the string is embedded in the armor plates and is difficult to be extracted from one end.
Although the combination of nail and tape has such drawbacks, there is no better choice.
