Description

Technical Field

[0001] This utility model relates to the field of compensation chain packaging technology, and more specifically, to a special packaging device for compensation chains. Background Technology

[0002] As a key component in elevators, lifting equipment, and other related fields, the compensating chain is mainly used to balance the weight difference between the car and the counterweight during equipment operation, ensuring stable operation. After the compensating chain is manufactured, it needs to be wound and arranged into a regular coil structure to facilitate subsequent storage, transportation, and to avoid bumps during handling.

[0003] However, significant protection challenges exist in the current compensation chain winding process: On the one hand, in traditional winding methods, the compensation chain is directly stacked and wound, with the outer and inner chain surfaces in direct contact. Under winding tension, friction and wear easily occur, leading to scratches on the protective coating and wear at the chain link connections. This not only affects the product's appearance integrity but may also weaken the chain's structural strength, shorten its service life, and even pose a threat to the stability of subsequent equipment installation and operation. On the other hand, to alleviate wear problems, some companies have attempted to use a single sheet of film to completely wrap the wound compensation chain, but this method has obvious limitations. First, complete wrapping requires the compensation chain to be fully wound, which is a cumbersome process, and the film's adhesion to the chain is poor. During transportation or storage, the film is prone to shifting or falling off, resulting in unstable protection. Second, single sheets of film have weak resistance to damage. If a hole is formed in the film during winding due to chain protrusions or external forces, the compensation chain in the damaged area will be directly exposed, failing to provide continuous and effective protection and still facing the risk of wear. For example, patent document publication number CN217263886U describes a special packaging device for compensation chains, which coats the surface of the compensation chain after winding. However, it still has some drawbacks in actual use, such as wear between the inner and outer layers of the compensation chain during winding, which not only affects the integrity of the product's appearance but may also weaken the strength of the chain structure, thus limiting its use. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a special packaging device for compensation chains to solve the problem that wear easily occurs between the inner and outer layers of the compensation chains during winding, which not only affects the integrity of the product appearance, but may also weaken the strength of the chain structure.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a special packaging device for compensation chains, comprising: a base plate, on the upper surface of the base plate a first fixed plate and a second fixed plate fixedly connected thereto, a movable plate disposed on the side of the second fixed plate, two movable plates being disposed and slidably connected to the upper surface of the base plate, a rotating ring being rotatably connected to both the first fixed plate and the second fixed plate, a post being fixedly connected to the side surface of the rotating ring, a winding roller being disposed between the rotating rings, a slot being disposed on the winding roller, the slot engaging with the post, and a plurality of slots being disposed on the rotating ring, a locking block being disposed in the slot, a plurality of films being rotatably connected to the side surface of the other movable plate, and a guide assembly being disposed on the first fixed plate.

[0006] The guiding component includes a second motor, a screw fixedly connected to the output end of the second motor, a second slider on the screw, a movable roller rotatably connected to the side surface of the second slider, a rotating roller below the movable roller, and the rotating roller rotatably connected to a first fixed plate.

[0007] The fixed plate has a movable groove, the screw and the slider are located in the movable groove, and the slider is slidably connected to the movable groove.

[0008] The bottom plate has a stop bar bolted to its side surface, and a hydraulic cylinder is fixedly connected to the upper surface of the stop bar.

[0009] The hydraulic cylinder is provided in two parts, and the output ends are respectively fixedly connected to the side surfaces of two movable plates near the stop bar.

[0010] The movable plate has a support plate fixedly connected to its side surface, and a motor is fixedly connected to the upper surface of the support plate.

[0011] The output end of the motor is connected to an angle encoder, and the output shaft of the angle encoder is fixedly connected to the rotating ring.

[0012] The base plate is provided with a sliding groove, and a slider is slidably connected in the sliding groove. The slider is fixedly connected to the lower surface of the movable plate.

[0013] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0014] In the above scheme, the rotating ring and the slots and blocks on the rotating ring can fix one end of the film. With the help of multiple sets of films, the compensation chain can be coated with film while it is being wound, so as to avoid wear between the film and the outer compensation chain during the winding process. At the same time, the multi-layer film can prevent the film from being damaged during the winding process and strengthen the protection of the compensation chain. Attached Figure Description

Detailed Implementation

[0021] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0022] As attached Figure 1 To be continued Figure 4 This utility model provides a special packaging device for compensation chains, comprising: a base plate 1, a fixing plate 6 and a fixing plate 7 fixedly connected to the upper surface of the base plate 1, a movable plate 4 disposed on the side of the fixing plate 7, a support plate 8 fixedly connected to the side surface of the movable plate 4, a motor 9 fixedly connected to the upper surface of the support plate 8, an angle encoder connected to the output end of the motor 9, the output shaft of the angle encoder being fixedly connected to a rotating ring 10, two movable plates 4 being provided, both slidably connected to the upper surface of the base plate 1, a rotating ring 10 rotatably connected to both the fixing plate 6 and the fixing plate 7, and a pin 2 fixedly connected to the side surface of the rotating ring 10. 0. A winding roller 12 is provided between the rotating rings 10. A slot 19 is provided on the winding roller 12. The slot 19 engages with the insert post 20. A number of slots 11 are provided on the rotating rings 10. A block 23 is provided in the slot 11. A number of films 5 are rotatably connected to the side surface of another movable plate 4. A guide assembly is provided on the fixed plate 6. The guide assembly includes a second motor 15. A screw 21 is fixedly connected to the output end of the second motor 15. A second slider 22 is provided on the screw 21. A movable roller 13 is rotatably connected to the side surface of the second slider 22. A rotating roller 14 is provided below the movable roller 13. The rotating roller 14 is rotatably connected to the fixed plate 6.

[0023] The fixed plate 16 is provided with a movable groove 18. The screw 21 and the slider 22 are located in the movable groove 18, and the slider 22 is slidably connected to the movable groove 18. The side surface of the base plate 1 is connected to the stop strip 2 by bolts. The upper surface of the stop strip 2 is fixedly connected to the hydraulic cylinder 3. There are two hydraulic cylinders 3, and the output ends are respectively fixedly connected to the side surface of the movable plate 4 near the stop strip 2. The base plate 1 is provided with a sliding groove 16. The slider 17 is slidably connected in the sliding groove 16. The slider 17 is fixedly connected to the lower surface of the movable plate 4.

[0024] Specifically, the hydraulic cylinder 3 is activated, and its output end pushes the movable plate 4 to slide along the groove 16 on the base plate 1. Guided by the slider 17, the distance between the two movable plates 4 is adjusted according to the length of the compensating chain winding roller 12, allowing the winding roller 12 to be smoothly placed between the fixed plate 6, the fixed plate 7, and the movable plate 4. The winding roller 12 is placed between the rotating rings 10, so that the inserts 20 on the rotating rings 10 are engaged in the slots 19 of the winding roller 12. One end of the compensating chain to be packaged is then fixed to the winding roller 12. One end of the film is then passed between the movable roller 13 and the rotating roller 14, and placed into the slot 11. The locking block 23 is then embedded into the slot 11 of the rotating ring 10 to fix the film. The motor 15 is activated and drives the screw 21 to rotate, causing the slider 22 to slide along the movable groove 18, thereby moving the movable roller 13 in conjunction with the rotating roller 14. Multiple films are guided to approach each other so that they can be wound onto the winding roller 12 with the compensation chain. Motor 9 is turned on, and its output end drives the rotating ring 10 to rotate through the angle encoder, which in turn drives the winding roller 12 to rotate synchronously and begin winding the compensation chain. As the winding roller 12 rotates, the film 5 on the side surface of the movable plate 4 is released synchronously, wrapping it while the compensation chain is being wound, forming a packaging protective layer. When the angle encoder detects that the winding roller 12 has reached the preset rotation angle, motor 9 and motor 15 stop working. At this time, the worker can cut the film with a blade and remove the clamp 23. The spacing of the movable plate 4 can be adjusted in the opposite direction by the hydraulic cylinder 3, and the packaged compensation chain roll can be removed from the winding roller 12.

[0025] The working process of this utility model is as follows: Start the hydraulic cylinder 3 to push the movable plate 4 to slide along the groove 16 of the base plate 1 via the slider 17. Adjust the distance between the two movable plates 4 according to the length of the winding roller 12 to ensure that the winding roller 12 can be placed between the fixed plate 6, the fixed plate 7, and the movable plate 4. Place the winding roller 12 between the rotating rings 10, so that the insert 20 on the rotating ring 10 is inserted into the slot 19 of the winding roller 12, and fix one end of the compensation chain to be packaged onto the winding roller 12. Pass one end of the film through the movable roller 13 and the rotating roller 14, and place it into the slot 11. Then, insert the clip 23 into the slot 11 of the rotating ring 10 to fix the film. Start the motor 15 to drive the screw 21 to rotate, so that the slider 22 slides along the movable groove 18, thereby driving the movable roller 13 to move, and cooperating with the rotating roller 14 to guide multiple films closer to the winding roller 12. Turn on the motor 9, and its output end drives the rotating ring 10 through the angle encoder. The rotation causes the winding roller 12 to rotate synchronously, starting the winding of the compensation chain. As the winding roller 12 rotates, the film 5 on the side surface of the movable plate 4 is released synchronously, forming a protective packaging layer during the winding of the compensation chain. The angle encoder detects that the winding roller 12 has reached the preset rotation angle, and motors 9 and 15 stop working. Then, the worker cuts the film with a blade, removes the clamp 23, and adjusts the spacing of the movable plate 4 in the opposite direction using the hydraulic cylinder 3 to remove the packaged compensation chain roll.
