[0019] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0020] See Figures 1 to 5This embodiment discloses a device to prevent disc-shaped auxiliary materials from falling off, including a fixed base 1, a support rod 2 fixedly mounted on the fixed base 1, and a clamping assembly on the support rod 2. The clamping assembly includes a plurality of clamping plates 3 distributed circumferentially along the support rod 2. The plurality of clamping plates 3 are evenly spaced along the circumferential direction of the support rod 2. A plurality of sliding grooves 4 are evenly spaced along the circumferential direction on the support rod 2. The plurality of clamping plates 3 are slidably disposed in the plurality of sliding grooves 4 in a corresponding manner, and the clamping plates 3 can extend and retract radially along the support rod 2 in the corresponding sliding grooves 4. The inner hole of the disc-shaped auxiliary material is tightened and clamped by the outer walls of the plurality of clamping plates 3. The clamping plates 3 can be made of rubber to avoid damage to the disc-shaped auxiliary material.

[0021] The support rod 2 is a hollow cylindrical structure with an internal lifting groove 5. The lifting groove 5 contains a drive assembly, which includes a motor 6 and a lead screw 7. The motor 6 is installed in the placement groove 8 at the top of the lifting groove 5. The lead screw 7 extends vertically and is rotatably installed in the lifting groove 5. The top of the lead screw 7 is connected to the output end of the motor 6. The lead screw 7 has two threaded sections 9 with opposite directions of rotation. The two threaded sections 9 of the lead screw 7 are respectively equipped with transmission structures. The two sets of transmission structures are symmetrically distributed vertically. Each set of transmission structures includes a lifting block 10 that is threadedly connected to the corresponding threaded section 9 of the lead screw 7. The outer periphery of the lifting block 10 is connected to several clamping plates 3 through several connecting rods 11. The two ends of the connecting rods 11 are respectively hinged to the clamping plates 3 and the lifting block 10. Specifically, one end of the connecting rod 11 is hinged to the lifting block 10 through a connecting shaft. The inner side of the clamping plate 3 has a vertically extending groove 12. The groove 12 contains a fixing rod 13. The other end of the connecting rod 11 is hinged to the clamping plate 3 through the fixing rod 13. The motor 6 drives the lead screw 7 to rotate, which in turn drives the upper and lower lifting blocks 10 to move in opposite directions vertically. The lifting blocks 10 are connected by several connecting rods 11 in the circumference of their respective lifting sides, which in turn pushes the clamping plate 3 to extend and retract radially. The clamping plate 3 is provided with limiting plates 14 on its inner and outer sides, which are used to abut against the inner and outer ends of the corresponding sliding grooves 4 on the support rod 2 to limit the radial extension and retraction of the clamping plate 3.

[0022] The top of the support rod 2 is provided with a positioning component, which includes a positioning plate 15 that can be detachably fitted onto the top of the support rod 2. The positioning plate 15 is used to vertically position and press the multiple disc-shaped auxiliary materials fitted onto the support rod 2.

[0023] The positioning assembly also includes a threaded rod 16 and a rotating ring 17. The threaded rod 16 is fixed to the top of the support rod 2. The rotating ring 17 is rotatably installed in the central hole of the positioning plate 15. The specific installation form of the rotating ring 17 and the positioning plate 15 is as follows: the bottom of the rotating ring 17 has an outwardly protruding limiting ring 18, and the inner wall of the central hole of the positioning plate 15 has a rotating groove 19. The rotating ring 17 and the positioning plate 15 are rotatably installed by the limiting ring 18 and the rotating groove 19. The rotating ring 17 is threadedly connected to the threaded rod 16. By rotating the rotating ring 17, the positioning plate 15 is driven to rise and fall on the threaded rod 16, thereby pressing or releasing the disc-shaped auxiliary material fitted on the support rod 2.

[0024] The base 1 has a fixing assembly at its bottom, which allows it to be attached to the platform. The fixing assembly includes a vacuum generator 20 and several suction cup assemblies. The base 1 has a mounting cavity 21 at its bottom, which is sealed by a connecting plate 22 fixed to the base 1. The connecting plate 22 has multiple anti-slip blocks 23 at its bottom. The connecting plate 22 can be made of rubber, and the anti-slip blocks 23 are integrally formed with the connecting plate 22 to increase friction between the device and the platform. The side wall of the base 1 has ventilation holes 24 communicating with the mounting cavity 21. The vacuum generator 20 is mounted on the top of the connecting plate 22. Each suction cup assembly includes a suction cup 25 and a connecting tube 26 connected to the top of the suction cup 25. The suction cup 25 is installed in a circular groove 27 at the bottom of the connecting plate 22. The connecting tube 26 at the top of the suction cup 25 passes upward through the connecting plate 22 and connects to the vacuum generator 20. The ventilation holes 24 facilitate the operation of the vacuum generator 20, enabling it to perform evacuation and inflation.

[0025] The connecting plate 22 has an annular groove 28 on its outer periphery. A magnetic ring 29 is embedded in the annular groove 28 of the connecting plate 22. The magnetic ring 29 can be a neodymium iron boron magnetic ring, which can make the device magnetically adsorbed onto the metal platform, effectively preventing the device from moving during transportation and causing the disc-shaped auxiliary material to fall off.

[0026] In use, the disc-shaped auxiliary materials are fitted onto the support rod 2, and multiple disc-shaped auxiliary materials are stacked vertically along the support rod 2. Then, the drive assembly is activated, and the motor 6 drives the lead screw 7 to rotate. The lead screw 7 drives the upper and lower lifting blocks 10 to move in opposite directions vertically. Through several connecting rods 11 around the two lifting blocks 10, the clamping plate 3 is pushed to extend and retract radially, so that the diameter of the circle formed by the outer walls of the multiple lifting blocks 10 increases. The outer walls of the clamping plate 3 tighten and clamp the inner hole of the disc-shaped auxiliary materials to radially clamp and fix the multiple disc-shaped auxiliary materials. Then, the positioning assembly is operated, and the rotating ring 17 is screwed onto the threaded rod 16. The rotating ring 17 is rotated, so that the rotating ring 17 drives the positioning plate 15 to move down. The positioning plate 15 can vertically press and position the multiple disc-shaped auxiliary materials placed on the support rod 2 to prevent the disc-shaped auxiliary materials from moving or tilting after being placed on the device, which would cause the disc-shaped auxiliary materials to fall off. The device is then placed on the platform, and the vacuum generator 20 is activated. Through the weight of the device itself and the negative pressure suction of each suction cup 25, the device is stably adhered to the platform. The platform is then placed on the conveyor rollers for transport. The device provided in this embodiment effectively prevents disc-shaped auxiliary materials from tilting and falling or tipping over during transport, solving the problem of material loss or conveyor equipment malfunction caused by disc-shaped auxiliary materials falling during transport, ensuring the normal operation of the conveyor equipment, improving its working efficiency, and reducing material waste.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
