Description

Technical Field

[0001] This utility model relates to the field of modular mesh belt technology, specifically a modular mesh belt that can be partially replaced. Background Technology

[0002] Modular mesh belts (also known as modular mesh belts or plastic steel mesh belts) are conveyor belt devices assembled from engineering plastic modules through interlocking hinge pins. In some aspects, they can directly replace conveyor belts for transmission and conveying. However, existing modular mesh belts still have certain defects in use. The existing mesh belt modules are composed of unidirectional rotating components. When a part of the mesh belt is damaged, the entire mesh belt at one end needs to be replaced, which undoubtedly increases maintenance costs. In addition, the existing modular mesh belts have a simple structure, making it inconvenient to maintain and replace parts, resulting in poor performance.

[0003] Patent CN211033992U discloses a modular mesh belt. The mesh belts are interlocked in an interlaced manner, and can be replaced individually when local damage occurs, reducing maintenance costs. Furthermore, the first and second connecting rods are connected to each other by rotating first and second mounting plates, and the external threads and nuts are mutually fixed, making it easy to disassemble and replace the first and second connecting rods.

[0004] In the aforementioned patent, the modular mesh belt solves the problems mentioned above. However, the modular mesh belt in this patent still has the following problems: during the partial disassembly and replacement of the modular mesh belt, the damaged area needs to be repaired by removing the bolts. The bolts need to be rotated using tools such as wrenches, and the rotation process requires manual operation. After disassembly, the bolts need to be rotated and installed in the initial position, which seriously affects the convenience of disassembly and replacement of the mesh belt.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing irrigation device structure. Utility Model Content

[0006] The purpose of this utility model is to provide a modular conveyor belt that can be partially replaced, in order to solve the problem mentioned in the background art that during the partial disassembly and replacement of the modular conveyor belt, it is necessary to remove the bolts to repair the damaged parts. However, the bolts need to be rotated with tools such as wrenches, and the rotation process requires manual operation. Furthermore, after the disassembly is completed, the bolts need to be rotated and installed in the initial position again, which seriously affects the convenience of disassembly and replacement of the conveyor belt.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a partially replaceable modular conveyor belt, including a conveyor belt connector and a first connecting shaft and a second connecting shaft rotatably mounted inside the conveyor belt connector; rotating connectors are rotatably mounted at both ends of the first and second connecting shafts, and a limiting square rod is fixedly mounted at the end of the rotating connector away from the first and second connecting shafts; a positioning sleeve is sleeved on the outer side of the limiting square rod; a positioning structure provided on the outer side of the positioning sleeve can quickly complete the disassembly of the positioning sleeve; and an adjustment structure provided on the outer side of the first and second connecting shafts can control the distance between the first and second connecting shafts.

[0008] Preferably, the adjustment structure includes a sliding ring, which is slidably mounted on the outside of the positioning sleeve, and two sets of limiting blocks are fixedly mounted on the side of the sliding ring near the positioning sleeve.

[0009] Preferably, the positioning sleeve has two sets of sliding grooves inside, and a connecting rope is fixedly connected to the outside of the limiting block.

[0010] Preferably, a docking block is slidably installed inside the sliding groove, and the side of the docking block near the limiting rod is inclined. A return spring is provided at one end of the docking block near the sliding groove, and the end of the docking block near the return spring is fixedly connected to the connecting rope.

[0011] Preferably, the outer side of the limiting rod is provided with two sets of limiting grooves, and the limiting grooves are engaged with the end of the docking block away from the reset spring.

[0012] Preferably, the adjustment structure includes a positioning connector, which is sleeved on the outside of the first connecting shaft and the second connecting shaft, and a positioning screw is fixedly installed on the outside of the positioning connector.

[0013] Preferably, the outer threads of the two sets of positioning screws are fitted with rotating screw cylinders, and the outer threads of the two sets of positioning screws inside the rotating screw cylinders rotate in opposite directions.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. By providing quick-release positioning sleeves on the outer sides of the first and second connecting shafts, the module mesh belt can be quickly disassembled, and parts of the module mesh belt can be disassembled, reducing the cost of using the module mesh belt and effectively improving the ease of use of the module mesh belt; 2. Furthermore, by rotating the screw barrel, the distance between the two sets of positioning screws inside can be adjusted, so that the positioning screw can drive the distance between the first connecting shaft and the second connecting shaft through the positioning connector, and the vertical spacing of the mesh belt connector can be adjusted. At the same time, the wear between the connecting shaft and the mesh belt can be reduced, ensuring the stability of the mesh belt operation. 3. Furthermore, by setting up the limiting block and the sliding ring, the separation between the limiting block and the limiting groove can be completed quickly, so that the positioning sleeve can be quickly disassembled from the limiting rod.

Detailed Implementation

[0017] 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.

[0018] In a specific embodiment, this utility model provides a technical solution: a partially replaceable modular mesh belt, such as... Figures 1-6 The basic usage process of the module's mesh belt is shown in the figure. The mesh belt connector 1 includes a first connecting shaft 2 and a second connecting shaft 3 rotatably mounted inside the mesh belt connector 1. Rotating connectors 4 are rotatably mounted at both ends of the first connecting shaft 2 and the second connecting shaft 3. A limiting square rod 5 is fixedly mounted at the end of the rotating connector 4 away from the first connecting shaft 2 and the second connecting shaft 3. A positioning sleeve 9 is sleeved on the outside of the limiting square rod 5. The positioning structure set on the outside of the positioning sleeve 9 can quickly complete the disassembly of the positioning sleeve 9. The adjustment structure set on the outside of the first connecting shaft 2 and the second connecting shaft 3 can control the distance between the first connecting shaft 2 and the second connecting shaft 3.

[0019] When using this partially replaceable modular mesh belt, the modular mesh belt needs to be installed on the outside of the conveyor shaft, and the mesh belt connector 1 is limited by the first connecting shaft 2 and the second connecting shaft 3. During the movement of the mesh belt connector 1, the upper outer object is conveyed. When the modular mesh belt is damaged, it can be disassembled. At this time, the positioning sleeve 9 needs to be removed, and then the positioning connector 6 can be removed. At the same time, the first connecting shaft 2 and the second connecting shaft 3 can be removed, and the damaged mesh belt connector 1 can be replaced, thereby reducing the cost of using the mesh belt.

[0020] In one specific embodiment, such as Figures 1-6 The specific disassembly process of the mesh belt is shown in the figure. The adjustment structure includes a sliding ring 10, which is slidably installed on the outside of the positioning sleeve 9. Two sets of limiting blocks 12 are fixedly installed on the side of the sliding ring 10 near the positioning sleeve 9. Two sets of sliding grooves 11 are opened inside the positioning sleeve 9. A connecting rope 14 is fixedly connected to the outside of the limiting block 12. A docking block 16 is slidably installed inside the sliding groove 11. The side of the docking block 16 near the limiting rod 5 is inclined. A return spring 13 is provided at the end of the docking block 16 near the sliding groove 11. At the same time, the end of the docking block 16 near the return spring 13 is fixedly connected to the connecting rope 14. Two sets of limiting grooves 15 are opened on the outside of the limiting rod 5. The limiting grooves 15 are engaged with the end of the docking block 16 away from the return spring 13.

[0021] When using this partially replaceable modular conveyor belt, the positioning sleeve 9 needs to be removed from the outside of the limiting rod 5 first. At this time, the sliding ring 10 needs to slide on the outside of the positioning sleeve 9, so that the sliding ring 10 is away from the first connecting shaft 2 and the second connecting shaft 3. During the sliding process, the sliding ring 10 will pull the limiting block 12 to move through the connecting rope 14. During the movement of the limiting block 12, it will move away from the limiting groove 15. During the movement of the limiting block 12, it will squeeze the return spring 13 and cause the return spring 13 to contract. After the limiting block 12 separates from the limiting groove 15, the positioning sleeve 9 can be moved away from the limiting rod 5, thus completing the disassembly process of the positioning sleeve 9 and the limiting rod 5. Then, the conveyor belt connector 1 on the outside of the first connecting shaft 2 and the second connecting shaft 3 can be replaced. After replacing the conveyor belt connector 1, the above process is reversed to install the positioning sleeve 9 on the outside of the limiting rod 5, thus completing the disassembly and replacement of the modular conveyor belt, effectively improving the convenience of the modular conveyor belt.

[0022] Based on the above embodiments, such as Figures 1-5 The adjustment process of the module's mesh belt is shown in the figure. The adjustment structure includes a positioning connector 6, which is sleeved on the outside of the first connecting shaft 2 and the second connecting shaft 3. A positioning screw 7 is fixedly installed on the outside of the positioning connector 6. A rotating screw cylinder 8 is installed on the outer threads of the two sets of positioning screws 7, and the outer threads of the two sets of positioning screws 7 inside the rotating screw cylinder 8 are rotated in opposite directions.

[0023] When using this partially replaceable modular conveyor belt, the positioning connector 6 needs to be removed during disassembly. After the conveyor belt connector 1 is disassembled, the positioning connector 6 needs to be installed in its initial position. After the positioning connector 6 is installed, the distance between the first connecting shaft 2 and the second connecting shaft 3 can be adjusted as needed to control the vertical distance between the conveyor belt connectors 1. During this process, the rotating screw cylinder 8 needs to be rotated. As the screw cylinder 8 rotates, the two sets of positioning screws 7 will move inside the rotating screw cylinder 8. During the movement of the two sets of positioning screws 7, the distance between the first connecting shaft 2 and the second connecting shaft 3 will be controlled through the positioning connector 6, thereby completing the vertical distance adjustment process of the conveyor belt connector 1. This effectively improves the convenience of using the modular conveyor belt and increases its overall practicality.

[0024] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
