Description
Technical Field
[0001] This utility model relates to the field of drive wheel technology, specifically a conveyor belt drive wheel that prevents deviation. Background Technology
[0002] Anti-deviation conveyor belt drive pulley is a pulley system device that passively corrects lateral deviation of the conveyor belt caused by uneven tension, load eccentricity, or external interference during operation through a special structural design, ensuring that the conveyor belt always runs stably along the predetermined path. Its core function is to maintain the alignment of the conveyor belt and avoid problems such as material spillage, edge wear, and equipment damage caused by deviation.
[0003] Patent document CN205687018U discloses a drive wheel for artificial leather conveyor belts, which "solves the problem of slippage and wear that often occurs in traditional conveyor belt drive wheels made of metal. The solution includes a drive wheel comprising a first pulley and a second pulley. The inner surface of the first pulley has multiple circumferentially distributed locking blocks, and the inner surface of the second pulley has locking grooves opposite to the locking blocks. The locking blocks and locking grooves are bolted together, forming a locking block and locking groove combination that combines the first and second pulleys into a drive wheel structure. The outer surface of the drive wheel has a wear-resistant rubber layer, and the outer surface of the rubber layer has friction roller patterns. This utility model has an ingenious structure that changes the structure of the conveyor belt drive wheel, greatly reducing slippage during drive, thereby reducing wear on the drive wheel and conveyor belt, lowering the maintenance rate, saving maintenance time and costs, and extending the service life of the drive wheel."
[0004] However, the aforementioned published document's proposed drive wheel for artificial leather conveyor belts mainly addresses the problem that traditional conveyor belt drive wheels, being made of metal, frequently slip and wear, making it difficult to automatically balance conveyor belt tension using centrifugal force.
[0005] In view of this, it is necessary to develop a dynamic balancing counterweight mechanism that can automatically balance the tension of the conveyor belt using centrifugal force, thereby reducing belt deviation caused by uneven tension. Utility Model Content
[0006] The purpose of this invention is to provide a conveyor belt drive pulley that prevents deviation, so as to solve the technical problem mentioned in the background art of enabling the conveyor belt drive pulley to have a dynamic balance counterweight function.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a conveyor belt drive wheel for preventing deviation, comprising: a drive wheel body and a connecting plate, wherein the outer wall of the connecting plate is provided with a dynamic balancing counterweight mechanism, which is used to automatically balance the tension of the conveyor belt using centrifugal force to reduce deviation caused by uneven tension.
[0008] The dynamic balancing counterweight mechanism includes a slide groove and a counterweight block. The outer wall of the connecting plate is provided with a slide groove, the inner wall of the slide groove is equipped with a slide rod, the outer wall of the slide rod is surrounded by a counterweight block, the outer wall of the slide rod is provided with a mounting screw groove, the outer wall of the slide rod is provided with a sealing plate, and the outer wall of the sealing plate is equipped with a mounting screw, one end of which extends into the interior of the mounting screw groove.
[0009] Preferably, a connecting plate is embedded in the inner wall of the drive wheel body.
[0010] Preferably, the outer wall of the drive wheel body is provided with a passive correction mechanism, which is used to correct the deviation of the conveyor belt.
[0011] Preferably, the passive correction mechanism includes a rubber sheet, an assembly screw groove, and an assembly screw.
[0012] Preferably, a rubber sheet is installed on the outer wall of the drive wheel body.
[0013] Preferably, the outer wall of the drive wheel body is provided with an assembly screw groove.
[0014] Preferably, an assembly screw is mounted on the outer wall of the rubber sheet, and one end of the assembly screw extends into the interior of the assembly screw groove.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. This utility model utilizes a dynamic balancing counterweight mechanism to automatically balance the conveyor belt tension using centrifugal force, reducing belt misalignment caused by uneven tension. First, the counterweight is moved to the outside of the slide bar in the chute. Then, counterweights are installed on both sides of the drive wheel body. Next, a sealing plate is moved to the end of the slide bar, and the mounting screw is fixed into the mounting screw groove. The sealing plate seals the chute and simultaneously limits the counterweight, thus automatically balancing the conveyor belt tension. When the conveyor belt shifts to the right, the right side is stretched, resulting in a decrease in tension on the right side; the left side is compressed, increasing tension on the left side. At this time, the forces on both sides of the drive wheel body are unbalanced, with a greater force on the left and a smaller force on the right. The counterweight on the slide bar generates centrifugal force as it rotates with the drive wheel body. When the forces on both sides of the wheel axle are uneven, the side with less tension (the right side) experiences the most force. The shaft undergoes slight elastic deformation, causing the counterweight to slide to that side due to centrifugal force during rotation. After sliding, the counterweight increases the load on the right axle, which is equivalent to "pulling back" the right conveyor belt, thereby balancing the tension and preventing deviation due to uneven tension. Specifically (for example): In the initial state, when the conveyor belt is running normally, the tension on both sides is balanced, and the counterweight is in the initial position. If the conveyor belt shifts to the right, the right side is stretched (tension decreases), while the left side is compressed (tension increases). The axle bends slightly because the left side is under greater force (the right side is relatively "relaxed"). When the counterweight rotates, the centrifugal force is directed outward. The "relaxation" on the right side causes the counterweight to slide to the right, increasing the load on the right side, which is equivalent to "tightening" the right conveyor belt. Then, the drive wheels at both ends return to straight, reducing deviation caused by uneven tension.
[0017] 2. This utility model passively corrects the conveyor belt offset by installing a passive correction mechanism. First, rubber sheets are attached to both sides of the drive wheel body. Then, the assembly screw is fixed into the assembly screw groove, thus installing the rubber sheets on both sides of the drive wheel body. When the conveyor belt offsets, the side guard is squeezed and deformed, generating a reverse elastic force to correct the offset. The working process is as follows: the conveyor belt offsets to the right - the right side guard is compressed → the elastic force pushes the conveyor belt back to the center. The amount of side guard deformation is proportional to the offset, forming an adaptive adjustment. The structure is simple and the cost is extremely low (only side guard material is required).

[0026] Please see Figure 1 and Figure 2 An anti-deviation conveyor belt drive wheel includes: a drive wheel body 1 and a connecting plate 2. The connecting plate 2 is embedded in the inner wall of the drive wheel body 1. The drive wheel body 1 is installed on the conveyor belt support by the connecting plate 2 and bolts. The drive wheel body 1 is a drive wheel that actively reduces the lateral deviation of the conveyor belt, so that the conveyor belt keeps the center aligned during operation. The surface of the drive wheel is designed with a symmetrical structure to ensure that the force on both sides of the conveyor belt is uniform and to avoid deviation caused by the asymmetry of the wheel body shape.
[0027] Please see Figure 2 and Figure 3The outer wall of the connecting plate 2 is provided with a dynamic balancing counterweight mechanism. This mechanism uses centrifugal force to automatically balance the tension of the conveyor belt, reducing belt misalignment caused by uneven tension. The dynamic balancing counterweight mechanism includes a chute 3 and a counterweight block 5. The outer wall of the connecting plate 2 has a chute 3, the inner wall of which is fitted with a slide rod 4. The outer wall of the slide rod 4 is surrounded by the counterweight block 5. The outer wall of the slide rod 4 has a mounting screw groove 6, and a sealing plate 7. A mounting screw 8 is installed on the outer wall of the sealing plate 7, with one end of the mounting screw 8 extending to… Inside the mounting groove 6, first move the counterweight 5 to the outside of the slide rod 4 in the slide 3, and then install the counterweights 5 on both sides of the drive wheel body 1 in sequence. Next, move the sealing plate 7 to the end of the slide rod 4 and fix the mounting screw 8 into the mounting groove 6. The sealing plate 7 then seals the slide 3 and limits the counterweight 5, thus automatically balancing the tension of the conveyor belt. When the conveyor belt shifts to the right, the right side of the conveyor belt is stretched, resulting in a decrease in tension on the right side; the left side is compressed, increasing the tension on the left side. At this time, the two sides of the drive wheel body 1... The forces on both sides are unbalanced, with greater force on the left and less on the right. The counterweight 5, mounted on the slide bar 4, generates centrifugal force as it rotates with the drive wheel 1. When the forces on both sides of the axle are uneven, the axle on the side with less tension (the right side) undergoes slight elastic deformation. This causes the counterweight 5 to slide towards that side due to centrifugal force during rotation. After sliding, the counterweight 5 increases the load on the right axle, effectively "pulling back" the right conveyor belt, thus balancing the tension and preventing deviation due to uneven tension. Specifically (for example): In the initial state... When the conveyor belt is running normally, the tension on both sides is balanced and the counterweight 5 is in the initial position. If the conveyor belt shifts to the right, the right side is stretched (tension decreases) while the left side is compressed (tension increases). The wheel axle bends slightly because the left side is under greater force (the right side is relatively "relaxed"). When the counterweight 5 rotates, the centrifugal force is directed outward. The "relaxation" on the right side causes the counterweight 5 to slide to the right side, increasing the load on the right side, which is equivalent to "tightening" the right side of the conveyor belt. Then the drive wheel body 1 at both ends returns to straightness, reducing deviation caused by uneven tension.
[0028] Please see Figure 1 , Figure 2 and Figure 4The outer wall of the drive wheel body 1 is equipped with a passive correction mechanism, which is used to correct the deviation of the conveyor belt. The passive correction mechanism includes a rubber sheet 9, an assembly screw groove 10, and an assembly screw 11. The outer wall of the drive wheel body 1 is equipped with a rubber sheet 9 and an assembly screw groove 10. The outer wall of the rubber sheet 9 is equipped with an assembly screw 11, and one end of the assembly screw 11 extends into the interior of the assembly screw groove 10. First, the rubber sheet 9 is attached to both sides of the drive wheel body 1. Then, the assembly screw 11 is fixed into the assembly screw groove 10. The rubber sheet 9 is installed on both sides of the drive wheel body 1. When the conveyor belt deviates, the side guard is squeezed and deformed, generating a reverse elastic force to correct the deviation. The working process is as follows: the conveyor belt deviates to the right - the right side guard is compressed → the elastic force pushes the conveyor belt back to the center. The deformation of the side guard is proportional to the deviation, forming an adaptive adjustment. The structure is simple and the cost is extremely low (only side guard material is required).
[0029] Working principle: The drive wheel body 1 is installed onto the conveyor belt support via connecting plate 2 and bolts. The drive wheel body 1 actively reduces the lateral offset of the conveyor belt, keeping the conveyor belt centered during operation. The surface of the drive wheel is designed with a symmetrical structure to ensure uniform force on both sides of the conveyor belt and avoid offset caused by asymmetrical wheel shape. First, the counterweight 5 is moved to the outside of the slide rod 4 in the slide groove 3. The counterweights 5 on both sides of the drive wheel body 1 are then installed in sequence. Subsequently, the sealing plate 7 is moved to the end of the slide rod 4, and the mounting screw 8 is fixed into the mounting screw groove 6. The sealing plate 7 then aligns with the slide groove. 3. When the seal simultaneously limits the counterweight 5, the tension of the conveyor belt is automatically balanced. When the conveyor belt shifts to the right, the right side of the conveyor belt is stretched, resulting in a decrease in tension on the right side; the left side is compressed, resulting in an increase in tension on the left side. At this time, the forces on both sides of the drive wheel body 1 are unbalanced, with a greater force on the left side and a smaller force on the right side. The counterweight 5, on the slide bar 4, generates centrifugal force when rotating with the drive wheel body 1. When the forces on both sides of the wheel axle are uneven, the wheel axle on the side with less tension (the right side) will undergo slight elastic deformation, causing the counterweight 5 to slide to that side due to centrifugal force during rotation. After sliding, the counterweight 5 increases in tension. This reduces the load on the right axle, effectively "pulling back" the right side of the conveyor belt, thus balancing the tension and preventing deviation due to uneven tension. Specifically (for example): In the initial state, when the conveyor belt is running normally, the tension on both sides is balanced, and counterweight 5 is in its initial position. If the conveyor belt shifts to the right, the right side is stretched (tension decreases), while the left side is compressed (tension increases). The axle bends slightly due to the greater force on the left side (the right side is relatively "relaxed"). When counterweight 5 rotates, the centrifugal force is outward. The "relaxation" on the right side causes counterweight 5 to slide to the right, increasing the load on the right side, which is equivalent to... When the right side of the conveyor belt is tightened, the two ends of the drive wheel body 1 return to straightness, reducing deviation caused by uneven tension. First, the rubber sheet 9 is attached to both sides of the drive wheel body 1. Then, the assembly screw 11 is fixed into the assembly screw groove 10. The rubber sheet 9 is installed on both sides of the drive wheel body 1. When the conveyor belt deviates, the side guard is squeezed and deformed, generating a reverse elastic force to correct the deviation. Working process: the conveyor belt deviates to the right - the right side guard is compressed → the elastic force pushes the conveyor belt back to the center. The deformation of the side guard is proportional to the deviation, forming an adaptive adjustment. The structure is simple and the cost is extremely low (only side guard material is required).
