Description

Technical Field

[0001] This utility model relates to the field of battery swapping technology, specifically to a battery conveyor belt limiting device and a battery swapping station having the same. Background Technology

[0002] With the popularization of new energy vehicles, there are two ways to replenish energy for these vehicles: charging piles and battery swapping. The mechanical mechanisms of different types of battery swapping stations vary, and there are also various structures for lifting the vehicle body, transferring and lifting the battery, and lifting the battery into the storage compartment. The most common structures are chain lifting, belt lifting, and gear and rack lifting.

[0003] Currently, belt conveyor systems offer advantages such as low noise and simple structure. However, due to the use of lifting pulleys, there are inherent errors in the machining of the pulley brackets, leading to numerous problems during assembly and operation. Depending on the equipment design, belts are generally flat belts without limiters and contain internal steel wires. Pulleys typically use flat pulleys with limiting grooves. The fit between these components requires relatively high machining and assembly precision. Uneven force distribution on both sides of the belt by the pulleys or retainers can easily cause uneven wear. Over long-term use, the belt inevitably experiences localized stretching, which can eventually lead to belt misalignment. When the belt misaligns and engages with the pulley limiters, it can cause wear and, in severe cases, safety accidents. Furthermore, currently, when the conveyor belt wears out, it can only be replaced directly. Replacing the belt is a cumbersome process, requiring the plant to be shut down before operation. It also requires professional personnel to perform the replacement, and after assembly, the pulleys, belt, and belt fasteners need to be repeatedly adjusted to ensure balance, which is difficult. Moreover, because the belt is connected to many components, the need to stop the plant during replacement means that the equipment cannot provide service, resulting in significant economic losses. The cost of replacing the belt and spare parts is also very high. Therefore, a battery conveyor belt limiting device needs to be designed to improve upon these problems. Utility Model Content

[0004] The battery conveyor belt limiting device of this utility model is designed to solve the technical problems of belt deviation during battery transfer and lifting and battery loading in battery swapping stations. The belt also exhibits jumping during movement and cannot return to its normal position after deviation, resulting in belt wear or breakage due to belt biting. This leads to a low service life of belts and other components, a high equipment failure rate, low safety, and consequently high operation and maintenance costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a battery conveyor belt limiting device, including a main frame, a transverse guide wheel, a longitudinal guide wheel, and a bracket.

[0011] Furthermore, a transverse guide channel is formed between the first transverse guide wheel and the second transverse guide wheel, the rotation axes of the first transverse guide wheel and the second transverse guide wheel are parallel, and the rotation axes of the first transverse guide wheel and the second transverse guide wheel are perpendicular to the frame fixing surface, respectively.

[0012] In some technical solutions of this utility model, the bracket includes a bracket fixing surface and a bracket assembly surface. The bracket fixing surface is connected to the bracket assembly surface. A third fixing hole is provided on the bracket fixing surface, and a fourth fixing hole is provided on the bracket assembly surface. The bracket fixing surface is tightly fitted to the frame fixing surface through a second fixing member passing through the second fixing hole and the third fixing hole.

[0013] In some technical solutions of this utility model, the bracket assembly surface includes a first bracket assembly surface and a second bracket assembly surface, which are respectively disposed on the edge of the bracket fixing surface.

[0014] Furthermore, a longitudinal guide wheel mounting channel is formed between the first bracket assembly surface and the second bracket assembly surface. The first bracket assembly surface and the second bracket assembly surface are parallel, and the first bracket assembly surface and the second bracket assembly surface are perpendicular to the bracket fixing surface, respectively.

[0015] In some technical solutions of this utility model, the longitudinal guide wheel includes a first longitudinal guide wheel and a second longitudinal guide wheel. The first longitudinal guide wheel and the second longitudinal guide wheel are arranged in the longitudinal guide wheel mounting channel. The first longitudinal guide wheel and the second longitudinal guide wheel are respectively connected to the first bracket assembly surface and the second bracket assembly surface in a rotatable manner through a third fixing member passing through a fourth fixing hole. The rotating shaft of the first longitudinal guide wheel and the second longitudinal guide wheel is the third fixing member.

[0016] Furthermore, a longitudinal guide channel is formed between the first longitudinal guide wheel and the second longitudinal guide wheel, the rotation axes of the first longitudinal guide wheel and the second longitudinal guide wheel are parallel, and the rotation axes of the first longitudinal guide wheel and the second longitudinal guide wheel are perpendicular to the first bracket assembly surface and the second bracket assembly surface, respectively.

[0017] Furthermore, the spacing of the longitudinal guide wheel mounting channels is no greater than the spacing of the transverse guide channels. In the battery swapping transmission system of the battery swapping station, the spacing of the transverse guide channels differs from the width of the conveyor belt by no more than 2mm, and the spacing of the longitudinal guide channels differs from the thickness of the conveyor belt by no more than 2mm.

[0018] Furthermore, the first fastener includes a first bolt, a first inner nut, and a first outer nut. The first bolt passes sequentially through the transverse guide wheel, the first inner nut, the first fixing hole, and the first outer nut to rotatably fix the transverse guide wheel to the frame fixing surface of the main frame. During tightening, two wrenches are needed to simultaneously tighten the first inner nut and the first outer nut on both sides of the first fixing hole to prevent the first bolt from shaking. The purpose is to lock the position of the transverse guide wheel for subsequent assembly.

[0019] Furthermore, the second fastener includes a second bolt and a second nut. The second bolt passes through the second fixing hole, the third fixing hole, and the second nut in sequence to tightly fit the frame fixing surface of the main frame with the bracket fixing surface of the bracket.

[0020] Furthermore, the third fastener includes a third bolt, a third inner nut, and a third outer nut. The third bolt passes sequentially through the longitudinal guide wheel, the third inner nut, the fourth fixing hole, and the third outer nut to rotatably fix the longitudinal guide wheel between the first and second bracket assembly surfaces of the bracket. During tightening, two wrenches are needed to simultaneously tighten the third inner and third outer nuts on both sides of the fourth fixing hole to prevent the third bolt from shaking. The purpose is to lock the position of the longitudinal guide wheel for subsequent assembly.

[0021] In some technical solutions of this utility model, a retaining ring may also be included, which is disposed between the transverse guide wheel and the main frame, and between the longitudinal guide wheel and the bracket. The retaining ring serves to limit the movement of the transverse guide wheel and the longitudinal guide wheel, while preventing wear caused by contact between the transverse guide wheel and the main frame, and between the longitudinal guide wheel and the bracket, or preventing excessive resistance that would prevent rotation.

[0022] This utility model also provides a battery swapping station, including the aforementioned battery conveyor belt limiting device.

[0023] In some technical solutions of this utility model, a battery conveyor belt is also included. The conveyor belt is confined within a transverse guide channel in the width direction and within a longitudinal guide channel in the thickness direction. During belt operation, the transverse guide wheel corrects the lateral deviation of the belt, ensuring the belt is positioned within the transverse guide channel. The longitudinal guide wheel limits the belt's movement during operation, ensuring the belt is positioned within the longitudinal guide channel, thus enabling the belt to run at a predetermined position on the pulley.

[0024] This utility model discloses a battery conveyor belt limiting device that, when installed in a battery swapping station, prevents belt misalignment caused by localized stretching after long-term use during battery transfer and loading. It corrects belt misalignment to the correct position and also corrects belt jerking, improving operational stability.

[0033] The embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0034] In the description of this utility model, it should be noted that the terms "vertical," "parallel," "edge," "end," "fitting," "upper," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "locking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. It should be pointed out that all accompanying drawings are exemplary representations. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] The battery conveyor belt limiting device of this utility model can effectively solve the technical problems of belt deviation during battery transfer and lifting and battery loading in battery swapping stations, as well as belt jumping during movement, belt deviation and inability to return to normal position, causing belt wear or breakage due to belt biting, resulting in low service life of belt and other components, high equipment failure rate, low safety, and thus high operation and maintenance costs.

[0037] The main frame and support of the battery conveyor belt limiting device of this utility model are made of ordinary carbon steel, or they can be made of stamped steel plate. The structure is simple and easy to process, lightweight, high-strength, and easy to install and replace. Bolts and guide wheels are commercially available parts, easy to procure, resulting in low maintenance costs. The rollers use built-in bearings, ensuring high durability, low sliding resistance, and low wear on the belt. After processing, the connection is achieved through the assembly of various components. The main frame and support are metal parts, and rust-proofing treatment is applied after processing to reduce maintenance costs.

[0038] To ensure ease of use and control processing costs, the device of this utility model is designed with ordinary carbon steel as the main frame (since the support is only 5mm thick, it can also be made by stamping steel plates of the same thickness). The structure is simple and easy to process, enabling mass production. Using a stamping method can greatly reduce manufacturing costs. At the same time, the structure is easy to install and can be temporarily added as needed. The guide wheel is a roller with an internal bearing. This type of roller has good rotation performance, low resistance, and high durability. The outer bushing is made of nylon material, which directly contacts the belt, reducing wear on the belt and improving its service life.

[0039] In use, the device of this utility model first assembles the transverse guide wheel onto the main frame and locks it with the first bolt, the first inner nut, and the first outer nut. Then, the main frame is installed at the maintenance position of the hoist belt, which corresponds to the center position of the pulley's operation. If the belt is a low-slip belt with minimal runout, the longitudinal guide wheel does not need to be installed; otherwise, it is required. This device can meet the needs of different scenarios and can be used on any structure that transmits power via a flat belt (without positioning grooves). Different guide wheel brackets can be designed according to different pulley fixing brackets, but the basic structure is consistent. This structure can be used in combination or independently, and can be assembled according to different needs. The built-in bearings of the transverse and longitudinal guide wheels are lubricated with grease before assembly, allowing for long-term use. Re-lubrication is also simple and has low maintenance costs.

[0040] This device is designed for two functions: firstly, it addresses the issue of uneven wear in the lateral direction caused by localized belt stretching, positioning the belt within the lateral guide channel; secondly, it prevents the belt from jumping up and down during operation, ensuring it remains within the longitudinal guide channel and runs at the predetermined position on the pulley. By adding this structure, the uneven wear problem that occurs with flat belts during operation can be effectively corrected, improving equipment operational stability and extending the service life of components.

[0041] This utility model proposes a battery conveyor belt limiting device, referencing... Figures 1 to 7 The following is an embodiment of the battery conveyor belt limiting device proposed in this utility model. The device will be described in detail below with reference to the specific drawings.

[0042] like Figures 1 to 5As shown, a battery conveyor belt limiting device of this utility model includes a main frame 1, a transverse guide wheel 2, a longitudinal guide wheel 3, and a bracket 4. The main frame 1 is provided with a plurality of first fixing holes 111, a plurality of second fixing holes 112, and a plurality of mounting holes 131. The bracket 4 is provided with a plurality of third fixing holes 411 and a plurality of fourth fixing holes 423. The transverse guide wheel 2 is connected to the main frame 1 through the first fixing hole 111 via a first fixing member 23. The bracket 4 is connected to the main frame 1 through the second fixing hole 112 and the third fixing hole 411 via a second fixing member 43. The longitudinal guide wheel 3 is connected to the bracket 4 through the fourth fixing hole 423 via a third fixing member 33.

[0043] Please refer to Figure 6 The main frame 1 includes a frame fixing surface 11, a frame bending surface 12, and a frame mounting surface 13. The frame fixing surface 11 is connected to the frame bending surface 12, and the frame bending surface 12 is connected to the frame mounting surface 13. The first fixing hole 111 and the second fixing hole 112 are provided on the frame fixing surface 11, and the mounting hole 131 is provided on the frame mounting surface 13.

[0044] Furthermore, the frame bending surface 12 includes a first frame bending surface 121 and a second frame bending surface 122, and the frame mounting surface 13 includes a first frame mounting surface 132 and a second frame mounting surface 133. The first frame bending surface 121 and the second frame bending surface 122 are respectively disposed at both ends of the frame fixing surface 11. The first frame mounting surface 132 is connected to the edge of the frame fixing surface 11 through the first frame bending surface 121, and the second frame mounting surface 133 is connected to the edge of the frame fixing surface 11 through the second frame bending surface 122. The first frame bending surface 121 and the second frame bending surface 122 are perpendicular to the frame fixing surface 11, and the first frame mounting surface 132 and the second frame mounting surface 133 are parallel to the frame fixing surface 11. The first frame mounting surface 132 and the second frame mounting surface 133 are on the same plane.

[0045] More specifically, there are two first fixing holes 111 and two second fixing holes 112. The two first fixing holes 111 and the two second fixing holes 112 are symmetrically arranged along the symmetry line of the middle part of the frame fixing surface 11. The two first fixing holes 111 are located outside the two second fixing holes 112 along the symmetry line of the middle part of the frame fixing surface 11. The first frame bending surface 121 and the second frame bending surface 122, as well as the first frame mounting surface 132 and the second frame mounting surface 133, are also symmetrically arranged along the symmetry line of the middle part of the frame fixing surface 11. This symmetrical arrangement ensures that the device remains balanced during operation, reduces vibration and wear caused by imbalance, thereby extending the service life of the device. It also simplifies assembly operations, reduces adjustment work during assembly, and improves production efficiency.

[0046] Please refer to Figure 7The bracket includes a bracket fixing surface 41 and a bracket assembly surface 42. The bracket fixing surface 41 is connected to the bracket assembly surface 42. A third fixing hole 411 is provided on the bracket fixing surface 41, and a fourth fixing hole 423 is provided on the bracket assembly surface 42. The bracket fixing surface 41 is tightly fitted to the frame fixing surface 11 through a second fixing member 43 passing through the second fixing hole 112 and the third fixing hole 411. The bracket assembly surface 42 includes a first bracket assembly surface 421 and a second bracket assembly surface 422, which are respectively provided on the edges of the bracket fixing surface 41. A longitudinal guide wheel mounting channel is formed between the first bracket assembly surface 421 and the second bracket assembly surface 422. The first bracket assembly surface 421 and the second bracket assembly surface 422 are parallel and perpendicular to the bracket fixing surface 41.

[0047] More specifically, the bracket fixing surface 41 is provided with two third fixing holes 411 that are connected to the second fixing holes 112 on the frame fixing surface 11. The first bracket assembly surface 421 and the second bracket assembly surface 422 are symmetrically arranged on the left and right sides along the symmetry line of the middle part of the frame fixing surface 11. The first bracket assembly surface 421 and the second bracket assembly surface 422 are respectively provided with two fourth fixing holes 423.

[0048] For reference Figures 1 to 5 The transverse guide wheel 2 includes a first transverse guide wheel 21 and a second transverse guide wheel 22. The first transverse guide wheel 21 and the second transverse guide wheel 22 are respectively rotatably connected to the frame fixing surface 11 through a first fixing member 23 passing through a first fixing hole 111. The first fixing member 23 is the axis of rotation of the first transverse guide wheel 21 and the second transverse guide wheel 22. A transverse guide channel is formed between the first transverse guide wheel 21 and the second transverse guide wheel 22. The axes of rotation of the first transverse guide wheel 21 and the second transverse guide wheel 22 are parallel and perpendicular to the frame fixing surface 11.

[0049] The longitudinal guide wheel 3 includes a first longitudinal guide wheel 31 and a second longitudinal guide wheel 32. The first longitudinal guide wheel 31 and the second longitudinal guide wheel 32 are disposed in the longitudinal guide wheel mounting channel. The first longitudinal guide wheel 31 and the second longitudinal guide wheel 32 are respectively connected to the first bracket assembly surface 421 and the second bracket assembly surface 422 rotatably through a third fixing member 33 passing through a fourth fixing hole 423. The rotation axis of the first longitudinal guide wheel 31 and the second longitudinal guide wheel 32 is the third fixing member 33. A longitudinal guide channel is formed between the first longitudinal guide wheel 31 and the second longitudinal guide wheel 32. The rotation axes of the first longitudinal guide wheel 31 and the second longitudinal guide wheel 32 are parallel and perpendicular to the first bracket assembly surface 421 and the second bracket assembly surface 422, respectively.

[0050] Furthermore, the spacing of the longitudinal guide wheel 3 installation channels is not greater than the spacing of the transverse guide channel 2. In the battery swapping transmission system of the battery swapping station, the spacing of the transverse guide channel is no more than 2mm different from the width of the conveyor belt, and the spacing of the longitudinal guide channel is no more than 2mm different from the thickness of the conveyor belt.

[0051] Specifically, the first fastener 23 includes a first bolt, a first inner nut, and a first outer nut. The first bolt passes sequentially through the transverse guide wheel 2, the first inner nut, the first fixing hole 111, and the first outer nut to rotatably fix the transverse guide wheel 2 to the frame fixing surface 11 of the main frame 1. During tightening, two wrenches are needed to simultaneously tighten the first inner nut and the first outer nut on both sides of the first fixing hole 111 to prevent the first bolt from shaking. The purpose is to lock the wheel position of the transverse guide wheel 2 for subsequent assembly.

[0052] The second fastener 43 includes a second bolt and a second nut. The second bolt passes through the second fixing hole 112, the third fixing hole 411 and the second nut in sequence to tightly fit the frame fixing surface 11 of the main frame 1 with the bracket fixing surface 41 of the bracket 4.

[0053] The third fastener 33 includes a third bolt, a third inner nut, and a third outer nut. The third bolt passes sequentially through the longitudinal guide wheel 3, the third inner nut, the fourth fixing hole 423, and the third outer nut, fixing the longitudinal guide wheel 3 rotatably between the first bracket assembly surface 421 and the second bracket assembly surface 422 of the bracket 4. During tightening, two wrenches are needed to simultaneously tighten the third inner nut and the third outer nut on both sides of the fourth fixing hole 423 to prevent the third bolt from shaking. The purpose is to lock the wheel position of the longitudinal guide wheel 3 for subsequent assembly.

[0054] Furthermore, the above-mentioned device may also include a retaining ring, which is disposed between the transverse guide wheel 2 and the main frame 1 and between the longitudinal guide wheel 3 and the bracket 4. The retaining ring provides a limiting function for the transverse guide wheel 2 and the longitudinal guide wheel 3, and at the same time prevents the transverse guide wheel 2 from contacting the main frame 1 and the longitudinal guide wheel 3 from contacting the bracket 4, causing wear or excessive resistance that prevents rotation.

[0055] This utility model's battery conveyor belt limiting device is applied in battery conveyor belts at battery swapping stations. The conveyor belt is confined within a transverse guide channel in the width direction and within a longitudinal guide channel in the thickness direction. During belt operation, the transverse guide wheel corrects lateral belt misalignment, ensuring the belt remains within the transverse guide channel. The longitudinal guide wheel limits belt movement during operation, ensuring the belt remains within the longitudinal guide channel, thus enabling the belt to run at a predetermined position on the pulleys.

[0056] The following are the specific steps for installing and using the battery conveyor belt limiting device of this utility model:

[0057] (1) Installation of main frame 1: First, take the first transverse guide wheel 21, then take the first fixing bolt, pass the first fixing bolt through the first transverse guide wheel 21, take the first inner nut to fix the first transverse guide wheel 21 and add a retaining ring to lock the position of the first transverse guide wheel 21, and obtain the pre-assembled first transverse guide wheel 21 assembly for subsequent assembly. Then, assemble the pre-assembled first transverse guide wheel 21 assembly onto the frame fixing surface 11 of the main frame 1 through the first fixing hole 111, take the first outer nut to lock the first transverse guide wheel 21 onto the main frame 1, and obtain the pre-assembled main frame 1 assembly. When locking, two wrenches are needed to simultaneously tighten the first inner nut and the first outer nut on both the inner and outer sides to prevent the bolt from shaking. Repeat the operation in step (1) to assemble the second transverse guide wheel 22 onto the main frame 1. After the assembly is completed, make a color mark at the nut locking point.

[0058] (2) Bracket Installation: Take the third bolt and insert it into the fourth fixing hole 423 of the second bracket assembly surface 422. Take the retaining ring and insert the third bolt together. Take the second longitudinal guide wheel 32 and pass the third bolt through the second longitudinal guide wheel 32. Then take the third inner nut to fix it and add the retaining ring to lock the position of the second longitudinal guide wheel 32. The third bolt passes through the fourth fixing hole 423 of the first bracket assembly surface 421 at the symmetrical position. Finally, take the third outer nut to lock the second longitudinal guide wheel 32 onto the bracket 4, obtaining the pre-assembled bracket assembly. When tightening, two wrenches are needed to simultaneously tighten the third inner nut and the third outer nut on both the inner and outer sides to prevent the bolt from shaking. After the second longitudinal guide wheel 32 is assembled, the first longitudinal guide wheel 31 is not installed temporarily. The first longitudinal guide wheel 31 will be installed after the entire device is assembled on the battery conveyor belt of the battery swapping station.

[0059] (3) Assemble the bracket assembly pre-installed in step (2) with the main frame 1 assembly pre-installed in step (1). Take the second bolt and pass it through the second fixing hole 112, the third fixing hole 411 and the second nut in sequence to tightly fit the frame fixing surface 11 of the main frame 1 with the bracket fixing surface 41 of the bracket 4, so that the bracket assembly pre-installed in step (2) and the main frame 1 assembly pre-installed in step (1) are locked together to obtain the assembled assembly.

[0060] (4) Install the assembly in step (3) onto the battery conveyor belt of the battery swapping station. Use fasteners to pass through the mounting holes 131 of the first frame mounting surface 132 and the second frame mounting surface 133 to assemble the main frame 1 into the battery conveyor belt of the battery swapping station. Note that the battery conveyor belt is between the first transverse guide wheel 21 and the second transverse guide wheel 22 and is placed on the second longitudinal guide wheel 32.

[0061] (5) After confirming that there are no problems in step (4), take the first longitudinal guide wheel 31, and then repeat the steps in (2) to install the first longitudinal guide wheel 31. Ensure that the conveyor belt is restricted in the transverse guide channel in the width direction and in the longitudinal guide channel in the thickness direction. When the belt is running, the first transverse guide wheel 21 and the second transverse guide wheel 22 correct the left and right deviation of the belt, so that the belt is located in the transverse guide channel. The first longitudinal guide wheel 31 and the second longitudinal guide wheel 32 limit the belt's jumping during operation, so that the belt is located in the longitudinal guide channel, enabling the belt to run at the predetermined position of the pulley.

[0062] This utility model's battery conveyor belt limiting device, through the design of the first transverse guide wheel 21 and the second transverse guide wheel 22, and the first longitudinal guide wheel 31 and the second longitudinal guide wheel 32, ensures that during the transfer and lifting of batteries in the battery swapping station, the conveyor belt does not deviate from its designated position, causing uneven belt wear or belt wear due to belt engagement with the pulley limiters, thus preventing safety accidents. Simultaneously, by adding this device to the battery swapping system, wear caused by belt contact with the pulley limiters is avoided, eliminating the need for belt replacement due to wear. It also reduces the difficulty of later maintenance, thus avoiding station shutdowns for replacements and preventing economic losses and increased spare parts costs.

[0063] This battery conveyor belt limiting device can be installed before the battery swapping equipment leaves the factory, or it can be retrofitted during later operation. The installation has no impact on the operation of the original battery swapping equipment, making it simple and convenient. The original design of this device is to correct the left and right deviation of the belt by using the transverse guide wheel when the belt is running, so that the belt is located in the transverse guide channel. The longitudinal guide wheel limits the belt's jump when it is running, so that the belt is located in the longitudinal guide channel, enabling the belt to run in the predetermined position of the pulley.

[0064] The technical solution of the above embodiment can be upgraded for the current device structure. The current mechanism can only ensure the correction of the belt's movement trajectory during operation, but cannot provide an early warning function when deviation occurs. The existing structure can be optimized to add an early warning function. Once the deviation is very large and affects the service life of the equipment, an alarm can be automatically triggered to stop the equipment and remind maintenance personnel to carry out maintenance and adjustment, ultimately improving safety and extending the service life of the equipment.
