Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, and in particular to an efficient automatic clamping and loosening device for conveyor belts that is easy to maintain. Background Technology

[0002] In logistics and transportation, manufacturing production lines and other fields, conveyor belts are key equipment for continuous material transport. Their stable operation is directly related to production efficiency and operational safety. During the installation, commissioning, maintenance and material loading and unloading of conveyor belts, it is often necessary to perform precise clamping or loosening operations to ensure that the tension of the conveyor belt is appropriate, the position is stable, or to facilitate maintenance work such as component replacement and fault diagnosis.

[0003] In the existing technology, the clamping and loosening of conveyor belts is usually done manually by using manual clamps. By adjusting bolts or screws with tools such as wrenches, the clamps are moved closer to or away from the conveyor belt to achieve clamping or loosening. Some semi-automatic devices use pneumatic or hydraulic cylinders as power sources, and the movement of the grippers is driven by the extension and retraction of the piston rod to complete the clamping and loosening of the conveyor belt.

[0004] However, in actual operation, existing conveyor belt clamping devices have significant limitations. Traditional manual clamping methods are not only labor-intensive and inefficient, but also difficult to precisely control the clamping force, easily leading to slippage due to excessively loose clamping or damage to the conveyor belt due to excessively tight clamping. While existing semi-automatic devices achieve power drive, their complex connection structures of core components such as slide bars and support plates lack convenient assembly and disassembly designs. When equipment malfunctions and requires maintenance or replacement of parts, it often requires a significant amount of time to disassemble multiple fasteners, resulting in a cumbersome and time-consuming maintenance process. Therefore, a convenient and efficient automatic conveyor belt clamping device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a convenient and efficient automatic clamping and loosening device for conveyor belts, aiming to improve the problem in the prior art where a lot of time is often spent disassembling multiple fasteners when the equipment malfunctions and needs maintenance or replacement of parts, resulting in a cumbersome maintenance process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An easy-to-maintain, high-efficiency automatic conveyor belt clamping and loosening device includes a frame and a support plate. A conveyor belt is installed inside the frame. A motor is fixedly connected to one side of the support plate, and a gear is fixedly connected to the motor's output end. Two connecting blocks are fixedly connected to the other side of the support plate. A threaded column is fixedly connected to one side of each connecting block. A slide rod one and a slide rod two are slidably connected to the outer walls of the two connecting blocks, respectively. A threaded sleeve is slidably connected inside slide rod one, and the threaded sleeve is threaded to the outer wall of the threaded column. A pulley is rotatably connected to one end of the threaded sleeve. A groove is formed inside slide rod one, and the pulley is rotatably connected inside the groove. A transmission assembly is provided on one side of both slide rod one and slide rod two, and a connecting assembly is provided on the side wall of the support plate.

[0008] The transmission assembly includes two racks, one side of which is fixedly connected to one side of slide rod one and slide rod two, respectively. Both racks mesh with the gear, and a clamp is fixedly connected to one side of slide rod one and slide rod two.

[0009] As a further description of the above technical solution:

[0010] The connecting assembly includes a mounting base and a hollow column. One side of the mounting base is fixedly connected to the side wall of the clamping plate, and the outer wall of the hollow column is fixedly connected to the inside of the mounting base. One side of the mounting base is in contact with one side of the conveyor belt.

[0011] As a further description of the above technical solution:

[0012] The hollow column is slidably connected with a pin, and the frame has multiple insertion holes, with the pin slidably connected to the corresponding insertion hole.

[0013] As a further description of the above technical solution:

[0014] The hollow column has a sliding column inside, and one end of the sliding column is fixedly connected to one end of the pin.

[0015] As a further description of the above technical solution:

[0016] The other end of the slide column is rotatably connected to a lever, and a spring is sleeved on the outer wall of the slide column. The two ends of the spring are respectively fixedly connected to the pin and the inside of the hollow column.

[0017] As a further description of the above technical solution:

[0018] The pin is fixedly connected to a fixing post, and the fixing post is slidably connected to a connecting post.

[0019] As a further description of the above technical solution:

[0020] One end of the connecting column is fixedly connected to a retaining bead, which engages with the inside of the frame.

[0021] As a further description of the above technical solution:

[0022] A second spring is fitted on the outer wall of the connecting column, and the two ends of the second spring are respectively fixedly connected to the inside of the fixing column and the pin.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the motor drives the gear to rotate, and the gear drives the rack connected to the two slide rods to move in opposite directions. At the same time, the threaded sleeve inside the slide rod is threadedly connected to the outer wall of the threaded column. The pulley at one end of the threaded sleeve rotates in the sliding groove inside the slide rod to assist sliding. This achieves the effect of convenient assembly and disassembly of the slide rod and the support plate, and solves the problem that when the equipment malfunctions and needs maintenance or replacement of parts, it is often necessary to spend a lot of time disassembling multiple fixed parts, which leads to a cumbersome maintenance process.

[0025] 2. In this utility model, the lever drives the sliding column and the pin to overcome the spring force and exit from the socket.

[0033] 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.

[0034] Reference Figures 1-3 This utility model provides an embodiment of an automatic and efficient conveyor belt clamping and loosening device that is easy to maintain. It includes a frame 1 and a support plate 3. The frame 1 is welded from Q235 steel plate, providing a stable installation foundation for the entire device and ensuring the stability of the conveyor belt 2 during operation. The conveyor belt 2 is installed inside the frame 1. A motor 4 is fixedly connected to one side of the support plate 3, and a gear 5 is fixedly connected to the output end of the motor 4. The motor 4 is a servo motor with an adjustable speed range of 0-1500 r / min. The output end is connected to the gear 5 via a key. Two connecting blocks 6 are fixedly connected to the other side of the support plate 3, and each connecting block 6 has a threaded connection on one side. The column 7 provides guidance and support for the sliding of the slide rod. The outer walls of the two connecting blocks 6 are slidably connected to slide rod 1 8 and slide rod 2 9 respectively. The inside of slide rod 1 8 is slidably connected to threaded sleeve 12, which is threaded to the outer wall of threaded column 7. One end of threaded sleeve 12 is rotatably connected to pulley 13. The inside of slide rod 1 8 is provided with slide groove 14, and pulley 13 is rotatably connected to the inside of slide groove 14, which can reduce the frictional resistance when slide rod 1 8 slides, making the sliding smoother. Both slide rod 1 8 and slide rod 2 9 are provided with transmission components on one side, which can realize the synchronous reverse movement of the slide rods. The side wall of support plate 3 is provided with connecting components, which can realize the quick connection and locking of the device and frame 1.

[0035] The transmission assembly includes two racks 10, one side of which is fixedly connected to one side of slide bar 8 and slide bar 9 respectively. Both racks 10 mesh with gear 5 to form a precise transmission structure. When the motor 4 drives the gear 5 to rotate, the two racks 10 move synchronously in opposite directions, causing slide bar 8 and slide bar 9 to slide on the outer wall of the connecting block 6. Each slide bar 8 and slide bar 9 is fixedly connected to one side with a clamping plate 11 made of polyurethane material with a thickness of 15-20mm. It has good elasticity and wear resistance, which can ensure a firm clamping when clamping the conveyor belt 2, while avoiding damage to the surface of the conveyor belt 2.

[0036] Reference Figure 2 , Figure 4 and Figure 5 The connecting assembly includes a mounting base 15 and a hollow column 16. One side of the mounting base 15 is fixedly connected to the side wall of the clamping plate 11. The mounting base 15 is made of cast steel. The outer wall of the hollow column 16 is fixedly connected to the inside of the mounting base 15. One side of the mounting base 15 is in contact with one side of the conveyor belt 2. A pin 17 is slidably connected inside the hollow column 16. Multiple insertion holes 25 are provided inside the frame 1. The pin 17 is slidably connected to the corresponding insertion hole 25, achieving the initial connection between the mounting base 15 and the frame 1. A sliding column 18 is slidably connected inside the hollow column 16. One end of the sliding column 18 is fixedly connected to one end of the pin 17, and the other end of the sliding column 18 is rotatably connected to a lever 20 made of engineering plastic. The surface is textured with anti-slip material for easy manual operation. A spring 19 is fitted onto the outer wall of the sliding column 18, with both ends of the spring 19 fixedly connected to the pin 17 and the hollow column 16, providing continuous elasticity to the pin 17 and ensuring its stable insertion into the insertion hole 25. A fixing post 21 is fixedly connected inside the pin 17, and a connecting post 23 is slidably connected inside the fixing post 21. A retaining bead 22 is fixedly connected to one end of the connecting post 23, engaging with the inside of the frame 1 to form a secondary lock, enhancing the connection's stability. A second spring 24 is fitted onto the outer wall of the connecting post 23, with both ends fixedly connected to the fixing post 21 and the pin 17, providing elasticity to the retaining bead 22 and ensuring it is tightly engaged inside the frame 1. This double-locking structure of the connecting components ensures a secure and reliable connection between the mounting base 15 and the frame 1, providing stable support for the clamping plate 11 to clamp the conveyor belt 2.

[0037] Working principle: When using this easy-to-maintain automatic conveyor belt clamping and loosening high-efficiency operation device, firstly, when it is necessary to clamp the conveyor belt 2, start the motor 4 fixed on one side of the support plate 3. The output end of the motor 4 drives the gear 5 to rotate. Since the two racks 10 are respectively fixed on one side of the slide rod 8 and the slide rod 9 and are both meshed with the gear 5, the rotation of the gear 5 will drive the two racks 10 to move in opposite directions, thereby driving the slide rod 8 and the slide rod 9 to slide on the outer wall of the connecting block 6. The clamping plate 11 fixed on one side of the slide rod 8 and the slide rod 9 will then move closer to clamp the conveyor belt 2 inside the frame 1. At the same time, when the slide rod 8 moves, the threaded sleeve 12 that is slidably connected inside it is threadedly connected to the outer wall of the threaded column 7. The pulley 13 that is rotatably connected to one end of the threaded sleeve 12 rotates in the sliding groove 14 inside the slide rod 8, assisting the slide rod 8 to slide stably, so that the slide rod 8 and the slide rod 9 can be easily assembled with the support plate 3.

[0038] When installing the clamping device, first, the mounting base 15 is placed against one side of the frame 1. At this time, the lever 20 drives the sliding column 18 and the pin 17 to overcome the elastic force of the spring 19 and exit from the insertion hole 25. As the mounting base 15 is in place with the frame 1, the lever 20 is released, and the spring 19 releases its elastic potential energy, pushing the sliding column 18 and the pin 17 to reset, so that the pin 17 is accurately inserted into the corresponding insertion hole 25 of the frame 1. At the same time, the retaining ball 22 inside the pin 17 is engaged with the inner wall of the frame 1 under the action of the second spring 24, forming a double lock. The first spring 19 provides a continuous axial elastic force, allowing the pin 17 to be stably embedded in the insertion hole 25, ensuring that the mounting base 15 is reliably connected to the frame 1, providing a stable support for the clamping plate 11 to clamp the conveyor belt 2, and completing the installation and locking of the key components of the clamping device.
