Description

Technical Field

[0001] This utility model relates to the technical field of multi-wedge belt roller conveyors, and in particular to a tooling for quick roller replacement and transmission of multi-wedge belts. Background Technology

[0002] The lithium battery industry is currently experiencing explosive growth in demand, with daily production line output requirements continuously increasing. Multi-wedge belt roller conveyors, as core conveying equipment connecting various processes in lithium battery production, directly determine the overall throughput of the production line due to their operational stability. Non-metallic multi-wedge belt drives, due to the absence of oil stains, metal wear debris, and lubrication, avoid contaminants affecting lithium battery quality, making them superior to traditional chain drives and the mainstream transmission method for lithium battery production line conveyor systems. However, the large daily conveying volume of production lines and the long-term high-load operation of multi-wedge belts make them prone to cracks, wear, or breakage, resulting in frequent replacements and making them a critical aspect of daily maintenance.

[0003] However, the current replacement of multi-ribbed belts lacks specialized tooling, leading to numerous problems that severely impact maintenance efficiency and equipment safety. Firstly, the natural span of the multi-ribbed belt is smaller than the initial spacing between adjacent rollers, making direct installation impossible. Multiple people must use pry bars or their bare hands to widen the gap; this process is labor-intensive and prone to slippage, potentially causing minor hand injuries or, in severe cases, roller misalignment and impact with surrounding equipment. Secondly, the lack of cushioning protection means that the rollers are prone to colliding with the frame or other rollers during prying, resulting in scratches, deformation, and even damage to internal bearings, increasing the risk of subsequent malfunctions. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a tooling for quick replacement of rollers and transmission multi-wedge belts. It aims to improve the existing multi-wedge belt replacement, which lacks dedicated tooling and requires multiple people to use pry bars or manually to pry the rollers to widen the gap, a process that is labor-intensive and prone to slippage.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a tooling for quickly changing rollers and driving multi-wedge belts, including a fixed base, a guide rod, a screw, a top seat, a nut sleeve, a first locking block, a second locking block, and two buffer blocks. The guide rod and the screw are both vertically fixed to the fixed base, and the guide rod and the screw are arranged parallel to each other. The top seat is movably sleeved on the guide rod and the screw, and the top seat can move upwards along the axial direction of the guide rod. The nut sleeve is threadedly engaged with the screw, and the nut sleeve abuts against the bottom of the top seat. Rotating the top seat... The nut sleeve drives the top seat to move up and down along the guide rod; the first locking block is fixed to the top of the top seat, and the second locking block is fixed to the top of the fixed seat, and the first locking block and the second locking block are arranged opposite each other to abut against two adjacent rollers; the two buffer blocks are respectively fixed to the top of the guide rod and the top of the screw to buffer and protect when in contact with the rollers; by rotating the nut sleeve to increase the distance between the top seat and the fixed seat, the first locking block and the second locking block can be driven away from each other, thereby increasing the distance between two adjacent rollers and realizing the quick installation and replacement of the multi-wedge belt.

[0006] Preferably, the guide rod and the fixed seat are fixedly connected by a cap nut, and an oil-free bushing is fitted on the guide rod, the oil-free bushing being located at the mating gap between the guide rod and the top seat.

[0007] Preferably, the screw and the fixed seat are fixedly connected by a cap nut, and the axis of the screw is parallel to the axis of the guide rod.

[0008] Preferably, the top seat has two mounting holes. One mounting hole houses a deep groove ball bearing, which is clearance-fitted with the screw. The other mounting hole houses an oil-free bushing, which is clearance-fitted with the guide rod.

[0009] Preferably, the first locking block is detachably fixed to the top seat by screws, and the second locking block is detachably fixed to the fixing seat by screws.

[0010] Preferably, the buffer block is made of polyurethane, and the buffer block is detachably fixed to the top of the guide rod and the top of the screw by screws respectively.

[0011] Preferably, a handle is fixedly provided on the outer peripheral wall of the nut sleeve, and the handle extends radially along the nut sleeve to facilitate gripping and rotating the nut sleeve to drive the top seat to rise.

[0012] Preferably, the oil-free bushing is fixedly connected to the inner wall of the mounting hole of the top seat by screws to prevent the oil-free bushing from moving with the guide rod.

[0013] Preferably, the top seat is further fixedly provided with an end cap, which covers the top of the mounting hole for mounting the deep groove ball bearing, so as to confine the deep groove ball bearing within the mounting hole.

[0014] Preferably, the contact surfaces of the first and second locking blocks facing the roller are both arc-shaped surfaces, and the curvature of the arc-shaped surfaces is adapted to the curvature of the outer circumference of the roller.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the tooling can accurately solve the key problem of insufficient roller spacing during multi-wedge belt installation, significantly improving the efficiency and operational stability of multi-wedge belt replacement. It provides a stable support foundation through a fixed base, and the parallel arrangement of the guide rod and screw ensures the structural verticality during the lifting and lowering of the top seat, avoiding spacing adjustment deviations caused by top seat offset. The threaded engagement between the nut sleeve and the screw provides reliable transmission performance, smoothly driving the top seat upwards along the guide rod during rotation. This causes the first and second locking blocks to move away from each other, thereby pushing adjacent rollers outwards to increase the spacing. This solves the problem of installation jamming caused by the initial roller spacing not reaching the natural span of the multi-wedge belt during traditional replacement, requiring multiple people to work together to pry the rollers.

[0017] The buffer block is fixed to the top of the guide rod and the screw, preventing surface scratches or deformation caused by direct collision between the roller and the guide rod / screw when the top seat rises to its limit or when the roller shakes slightly, thus protecting the integrity of the conveyor equipment components. The overall structure requires no complex electric drive; the spacing can be adjusted simply by manually rotating the nut sleeve. Operation is simple and easy to learn; maintenance personnel can quickly master the method without professional training, effectively shortening the maintenance time for replacing multi-ribbed belts.

[0018] 2. In this utility model, the oilless bushing and the deep groove ball bearing reduce the frictional resistance between the guide rod and the top seat, and between the screw and the top seat, respectively. This not only makes the lifting process of the top seat smoother, but also reduces the wear of components after long-term use and extends the overall service life of the tooling. The end cover covers the top of the mounting hole for installing the deep groove ball bearing, which can stably confine the bearing in the hole and prevent the bearing from dislodging with the screw rotation, thus avoiding equipment failure and improving the reliability of the tooling operation.

[0019] The handle extends radially along the outer circumference of the nut sleeve, making it easy for operators to grip and apply force. It is less strenuous than directly rotating the nut sleeve, especially reducing hand fatigue during frequent maintenance operations. The first and second locking blocks are detachably fixed to the top seat and the fixed seat respectively by screws. If the locking blocks are worn or deformed due to long-term use, they can be removed and replaced individually without replacing the entire tooling, thus reducing maintenance costs.

[0020] The buffer block is made of polyurethane, which has good elasticity and wear resistance. When in contact with the roller, it can effectively buffer the impact force and prevent itself from wearing out too quickly after long-term use, thus further ensuring the protection of the roller and tooling components. The oilless bushing is fixed to the inner wall of the mounting hole of the top seat with screws, which can prevent the oilless bushing from moving with the guide rod when the top seat is raised and lowered, ensuring that the oilless bushing is always in a stable lubrication position and continuously plays a drag reduction role.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1, refer to Figures 1-3A tooling for quick replacement of rollers and transmission multi-wedge belts includes a fixed base 2, a guide rod 3, a screw 7, a top seat 1, a nut sleeve 6, a first locking block 51, a second locking block 52, and two buffer blocks 4. The guide rod 3 and the screw 7 are both vertically fixed to the fixed base 2, and are arranged parallel to each other. The top seat 1 is movably sleeved on the guide rod 3 and the screw 7, and can move upwards along the axis of the guide rod 3. The nut sleeve 6 is threadedly engaged with the screw 7, and abuts against the bottom of the top seat 1. Rotating the nut sleeve 6 drives the top seat 1 along the guide rod... 3. Lifting and lowering: The first locking block 51 is fixed to the top of the top seat 1, and the second locking block 52 is fixed to the top of the fixed seat 2. The first locking block 51 and the second locking block 52 are arranged opposite each other to abut against the two adjacent rollers. The two buffer blocks 4 are respectively fixed to the top of the guide rod 3 and the top of the screw 7 to buffer and protect when in contact with the rollers. By rotating the nut sleeve 6, the distance between the top seat 1 and the fixed seat 2 is increased, which can drive the first locking block 51 and the second locking block 52 away from each other, thereby increasing the distance between the two adjacent rollers and realizing the quick installation and replacement of the multi-wedge belt.

[0028] The nut sleeve 6 is threadedly engaged with the screw 7 and abuts against the bottom of the top seat 1. When rotated, it can drive the top seat 1 to rise along the parallel guide rod 3 and screw 7, causing the first locking block 51 on the top of the top seat 1 to move away from the second locking block 52 on the top of the fixed seat 2 to increase the roller spacing. The buffer block 4 at the top of the guide rod 3 and screw 7 can prevent the rollers from colliding and being damaged, thereby solving the problem of the roller spacing being too small and realizing the quick replacement of multi-wedge belts. The parallelism between the guide rod 3 and screw 7 ensures that the top seat 1 does not deviate, and the threaded engagement provides stable transmission.

[0029] Example 2, refer to Figures 1-3Based on Embodiment 1, the guide rod 3 and the fixed seat 2 are fixedly connected by a cap nut, and an oil-free bushing 10 is fitted on the guide rod 3. The oil-free bushing 10 is located at the fit gap between the guide rod 3 and the top seat 1. The oil-free bushing 10 allows the top seat 1 to move more smoothly along the guide rod 3, and the cap nut ensures that the guide rod 3 is fixed and does not loosen. The cap nut can prevent the guide rod 3 from loosening, and the oil-free bushing 10 can reduce the frictional resistance between the guide rod 3 and the top seat 1. The screw 7 and the fixed seat 2 are fixedly connected by a cap nut, and the axis of the screw 7 is parallel to the axis of the guide rod 3. The screw 7 is firmly fixed and the top seat 1 does not deviate when moving along it. The cap nut can prevent the screw 7 from falling off, and the parallel axes can ensure that the top seat 1 is evenly stressed and does not tilt. The top seat 1 has two mounting holes. One mounting hole houses a deep groove ball bearing, which has a clearance fit with the screw 7. The other mounting hole houses an oil-free bushing 10, which has a clearance fit with the guide rod 3. The deep groove ball bearing and the oil-free bushing 10 significantly reduce friction between the top seat 1 and the screw 7 and guide rod 3, making the lifting and lowering of the top seat 1 smoother. The deep groove ball bearing reduces friction when the screw 7 rotates, and the oil-free bushing 10 reduces sliding friction between the guide rod 3 and the top seat 1. The first locking block 51 is detachably fixed to the top seat 1 by screws, and the second locking block 52 is detachably fixed to the fixed seat 2 by screws. When the locking blocks wear out, they can be removed and replaced individually without replacing the entire tooling, thus reducing maintenance costs. The screw connection is detachable, allowing for individual removal and installation of the locking blocks. The buffer block 4 is made of polyurethane, and the buffer block 4 is detachably fixed to the top of the guide rod 3 and the top of the screw 7 by screws respectively. When the buffer block 4 comes into contact with the roller, it effectively buffers the impact force and is wear-resistant and durable, protecting the roller and tooling parts. The polyurethane material has its own elasticity and can absorb the impact force. The screw fixing can ensure that the buffer block 4 is firmly installed and easy to replace.

[0030] Example 3, refer to Figures 1-3Based on Embodiment 1 or Embodiment 2, a handle 9 is fixedly provided on the outer peripheral wall of the nut sleeve 6. The handle 9 extends radially along the nut sleeve 6 to facilitate gripping and rotating the nut sleeve 6 to drive the top seat 1 to rise. Gripping the handle 9 to rotate the nut sleeve 6 requires less effort from the operator, reducing hand fatigue from frequent operation. The handle 9 increases the lever arm during rotation, allowing the operator to easily drive the nut sleeve 6 to rotate without direct force. The oil-free bushing 10 is fixedly connected to the inner wall of the mounting hole of the top seat 1 by screws to prevent the oil-free bushing 10 from moving with the guide rod 3. The oil-free bushing 10 is always within the fit gap between the guide rod 3 and the top seat 1, continuously playing a drag-reducing role. The screw fixation restricts the displacement of the oil-free bushing 10, keeping its position stable. An end cap 8 is also fixedly installed on the top seat 1. The end cap 8 covers the top of the mounting hole for installing the deep groove ball bearing, thereby confining the deep groove ball bearing within the mounting hole. The end cap 8 confines the deep groove ball bearing within the mounting hole, preventing the deep groove ball bearing from detaching from the top seat 1 and causing tooling failure. The end cap 8 forms an axial limit on the deep groove ball bearing, preventing the bearing from coming off upward. The contact surfaces of the first locking block 51 and the second locking block 52 facing the roller are both arc-shaped surfaces. The curvature of the arc-shaped surface matches the curvature of the outer circumference of the roller. The arc-shaped surface increases the contact area between the locking block and the roller, preventing the locking block from slipping and causing the roller to shift when adjusting the spacing, ensuring accurate spacing adjustment. The matching curvature allows the arc-shaped surface to fit tightly against the outer circumference of the roller, and the increased contact area improves friction and prevents relative sliding.

[0031] Working principle: When using this quick-change roller and drive multi-ribbed belt tooling, first place the tooling between two adjacent rollers of the multi-ribbed belt to be replaced, ensuring the fixed base 2 remains horizontal and stable. Then, abut the second locking block 52, fixed to the top of the fixed base 2, against the outer circumferential surface of one of the rollers. Next, adjust the initial position of the top base 1 so that the first locking block 51, fixed to the top of the top base 1, abuts against the outer circumferential surface of the other adjacent roller. At this time, both the guide rod 3 and the screw 7 are vertically fixed on the fixed seat 2. They are arranged in parallel and together provide support for the top seat 1. The oilless bushing 10 is fitted in the gap between the guide rod 3 and the top seat 1. The deep groove ball bearing is installed in the mounting hole of the top seat 1 corresponding to the screw 7. These two components can reduce the frictional resistance between the guide rod 3 and the top seat 1, and between the screw 7 and the top seat 1, respectively, ensuring that the top seat 1 can move smoothly along the axial direction of the guide rod 3. At the same time, the buffer block 4 at the top of the guide rod 3 and the screw 7 is located above the top seat 1, which can prevent the top of the guide rod 3 and the screw 7 from directly contacting the roller during the rising process of the top seat 1 and causing collision damage.

[0032] When the tooling is laid horizontally and fixed between two horizontally adjacent rollers, the operator holds the handle 9 on the outer peripheral wall of the nut sleeve 6 and rotates the nut sleeve 6 clockwise. Since the nut sleeve 6 and the screw 7 are threaded together, and the bottom of the nut sleeve 6 abuts against the bottom of the top seat 1, the nut sleeve 6 moves upward along the axis of the screw 7 during rotation, thus generating an upward thrust on the top seat 1. Under this thrust, the top seat 1 moves smoothly upward along the axis of the guide rod 3, simultaneously driving the first locking block 51 at the top to move upward synchronously. At this time, the second locking block 52 fixed on the fixed seat 2 remains in place, and the distance between the first locking block 51 and the second locking block 52 gradually increases as the top seat 1 rises. Both blocks exert outward thrust on the two adjacent rollers, causing the distance between the two rollers to continuously increase until the distance reaches a size that allows for easy installation of multi-wedge belts. During this process, the end cap 8 on the top seat 1 covers the top of the mounting hole for the deep groove ball bearing, which can confine the deep groove ball bearing within the mounting hole and prevent the deep groove ball bearing from detaching from the top seat 1 as the screw 7 rotates. After the multi-ribbed belt is successfully installed on the two rollers, the operator rotates the handle 9 counterclockwise to move the nut sleeve 6 downward. Under its own gravity, the top seat 1 resets downward along the guide rod 3, and the gap between the first locking block 51 and the second locking block 52 is reduced. Then, the tooling is removed from between the two rollers, and the multi-ribbed belt replacement operation is completed.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
