Description

Technical Field

[0001] This utility model is an automatic chain winding device, belonging to the field of chain winding equipment. Background Technology

[0002] Chain winding equipment is a mechanical device used to collect, store and manage chains. It can wind up the chain placed on the winding roller by driving the winding roller through an electric shaft.

[0003] In the prior art, a limiting rod is fixedly installed above the chain winding roller to effectively limit the chain condition during winding, preventing the chain from becoming loose during winding and facilitating the user's storage. However, chain sizes vary, and the diameter of the winding drum varies for different chain sizes. As a result, the limiting rod can only limit and fix chain rolls of a specified size, making the fixed adaptation range of the automatic chain winding device narrow.

[0004] In summary, this utility model provides an automatic chain winding device to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic chain winding device to solve the problem of the narrow range of chain winding fixation mentioned in the background art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an automatic chain winding device, comprising a base, an electric rotating shaft, and a winding roller. Fixed plates are fixedly connected to both sides of the top of the base. The electric rotating shaft is rotatably mounted between opposite sides of the two fixed plates. The winding roller is sleeved outside the electric rotating shaft. Baffles are sleeved on both ends of the winding roller outside the electric rotating shaft. A strip-shaped groove is formed on the front of the winding roller. Strip-shaped airbags are fixedly installed at the top and bottom of the inner wall of the strip-shaped groove. A flexible limiting component is installed between opposite sides of the two baffles and directly above the winding roller.

[0007] Furthermore, the baffle is fixedly connected to the winding roller, and the winding roller is fixedly connected to the electric rotating shaft.

[0008] Furthermore, the flexible limiting component includes two movable slots, which are respectively opened on opposite sides of the two baffles and located directly above the take-up roller. A compression spring is fixedly installed on the top of the inner wall of each of the two movable slots. Movable blocks are fixedly connected to the bottom ends of the two compression springs and inside the two movable slots. A connecting plate is fixedly installed between opposite sides of the two movable blocks. Mounting plates are fixedly connected to both sides of the bottom of the connecting plate. A mounting shaft is rotatably connected between opposite sides of the two mounting plates via a bearing. A limiting roller is sleeved on the outside of the mounting shaft.

[0009] Furthermore, the roller surface of the limiting roller is fitted with a rubber sleeve.

[0010] Furthermore, the three sides of the movable block are in contact with the inner wall of the movable groove, and both baffles are circular plates.

[0011] Furthermore, one side of the movable block is flush with one side of the baffle, and both sides of the connecting plate are in contact with the opposite sides of the two baffles.

[0012] The beneficial effects of this utility model are:

[0013] The chain is wound by the take-up roller, increasing the overall diameter of the chain coil. This allows the chain coil to push the connecting plate, which in turn moves two movable blocks. As the two movable blocks slide smoothly within the movable groove, they compress two compression springs. The rebound force of the two compression springs pushes the movable blocks, connecting plate, mounting plate, and mounting shaft in the opposite direction, pushing the limit roller to apply a reaction force to the chain coil. This ensures that the chain coil does not become loose after winding. Furthermore, the limit fixing can be flexibly adjusted according to different chain coils, effectively expanding the chain coil fixing adaptation range of the automatic chain take-up device.

[0014] The end of the chain is embedded between two strip-shaped air bladders inside the strip groove. The outer surface of the strip-shaped air bladders is made of rubber, which can be elastically stretched and deformed. This allows chains with a width greater than the distance between the two strip-shaped air bladders to be elastically locked into the inside of the strip groove. This enables chain ends of different sizes to be quickly fixed on the winding roller, expanding the adaptability of the automatic chain winding device. The chain end fixing operation is simple and convenient, which improves the chain winding processing efficiency.

[0015] The limiting roller can rotate as the chain is wound up, which reduces the resistance of the limiting roller to the chain and improves the chain winding efficiency.

[0016] A rubber sleeve is fitted over the outside of the limiting roller. The rubber sleeve prevents the limiting roller from directly squeezing the chain, thus preventing chain deformation and effectively improving the chain winding process quality. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figure 1-4This utility model provides a technical solution: an automatic chain winding device, including a base 1, an electric rotating shaft 3, and a winding roller 4. Fixing plates 2 are fixedly connected to both sides of the top of the base 1. The electric rotating shaft 3 is rotatably mounted between opposite sides of the two fixing plates 2. The winding roller 4 is sleeved outside the electric rotating shaft 3. Baffles 5 are sleeved on both ends of the winding roller 4 outside the electric rotating shaft 3. A strip-shaped groove 6 is formed on the front of the winding roller 4. Strip-shaped airbags 7 are fixedly installed at the top and bottom of the inner wall of the strip-shaped groove 6. The spacing between the strip-shaped airbags 7 is smaller than the width of the chain, thereby allowing the chain end to be directly engaged with the inner sides of the two strip-shaped airbags 7. The outer part of the strip-shaped airbag 7 is made of rubber, which can be elastically stretched and deformed, so that chains with a width greater than the distance between the two strip-shaped airbags 7 can be elastically locked into the inside of the strip-shaped groove 6. A flexible limiting component 8 is installed between the opposite sides of the two baffles 5 and directly above the take-up roller 4. The electric shaft 3 is a device that integrates a motor and a shaft. The electric shaft 3 is connected to an external power source and is equipped with a power control switch. The take-up roller 4 can be rotated through the electric shaft 3, so that the chain can be wound. The baffles 5 are fixedly connected to the take-up roller 4, and the take-up roller 4 is rotatably connected between the two baffles 5 through the electric shaft 3.

[0025] Please see Figure 2-4 The flexible limiting component 8 includes two movable slots 81, which are respectively opened on the opposite side of the two baffles 5 and located directly above the take-up roller 4. A compression spring 82 is fixedly installed on the top of the inner wall of each of the two movable slots 81. Movable blocks 83 are fixedly connected to the bottom of the two compression springs 82 and inside the two movable slots 81. A connecting plate 84 is fixedly installed between the opposite sides of the two movable blocks 83. Mounting plates 85 are fixedly connected to both sides of the bottom of the connecting plate 84. A mounting shaft 86 is rotatably connected between the opposite sides of the two mounting plates 85 through a bearing. A limiting roller 87 is sleeved on the outside of the mounting shaft 86.

[0026] Please see Figure 2-4 The roller surface of the limiting roller 87 is fitted with a rubber sleeve 88. The limiting roller 87 is fixedly connected to the mounting shaft 86. The rubber sleeve 88 can prevent the limiting roller 87 from directly squeezing the chain and prevent the chain from deforming. The three sides of the movable block 83 are in contact with the inner wall of the movable groove 81. The two baffles 5 are both circular plates. One side of the movable block 83 is flush with one side of the baffle 5. The two sides of the connecting plate 84 are in contact with the opposite sides of the two baffles 5 respectively.

[0027] Detailed implementation: By placing the end of the chain to be wound above the winding roller 4 and passing it under the flexible limiting component 8, the end of the chain is embedded between two strip-shaped airbags 7 inside the strip groove 6. The distance between the strip-shaped airbags 7 is less than the width of the chain, so the end of the chain can be directly locked into the inside of the two strip-shaped airbags 7. The outside of the strip-shaped airbags 7 is made of rubber, which can be elastically stretched and deformed, so that chains with a width greater than the distance between the two strip-shaped airbags 7 can be elastically locked into the inside of the strip groove 6. This allows chain ends of different sizes to be quickly fixed on the winding roller 4, expanding the adaptability of the automatic chain winding device. The chain end fixing operation is simple and convenient, which improves the chain winding processing efficiency.

[0028] The electric rotating shaft 3 is started, driving the winding roller 4 to rotate. The winding roller 4 can drive the chain to wind. As the number of turns of the chain increases, the overall diameter of the chain roll increases, which can push the connecting plate 84 to move. The connecting plate 84 drives the two movable blocks 83 to move. While the two movable blocks 83 slide smoothly inside the movable groove 81, they can squeeze the two compression springs 82. The rebound force of the two compression springs 82 can push the movable blocks 83 and the connecting plate 84 to move in the opposite direction. The connecting plate 84 pushes the limiting roller 87 through the mounting plate 85 and the mounting shaft 86 to apply a reaction force to the chain roll, ensuring that the chain is squeezed by the limiting roller 87 after winding, and the chain roll will not become loose. Moreover, the compression springs 82 can be flexibly squeezed, so the position of the limiting roller 87 can be flexibly adjusted. The limiting and fixing can be flexibly adjusted according to different chain rolls, which effectively expands the chain roll fixing and adaptation range of the automatic chain winding device.

[0029] Furthermore, the limiting roller 87 can rotate as the chain is wound up, thereby reducing the resistance of the limiting roller 87 to the chain and improving the chain winding efficiency.

[0030] The rubber sleeve 88 is fitted over the outside of the limiting roller 87. The rubber sleeve 88 can prevent the limiting roller 87 from directly squeezing the chain, thus preventing chain deformation and effectively improving the chain winding process quality.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
