Description

Technical Field

[0001] This utility model relates to the field of paper tubes, and in particular to a paper tube for fiber winding. Background Technology

[0002] Fibers are substances composed of continuous or discontinuous filaments. In plants and animals, fibers play an important role in maintaining tissues. Fibers have a wide range of uses. They can be woven into fine threads, yarns, and ropes. They can also be woven into fiber layers in papermaking or felt weaving. They are also often used to manufacture other materials and to form composite materials with other materials.

[0023] 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.

[0024] This utility model provides, for example Figure 1-3 The paper tube shown includes a paper tube body 1, on which a binding assembly 2 is provided. The binding assembly 2 includes a first connecting sleeve 21, a second connecting sleeve 22, a protective disc 23, and a docking assembly 24. The outer walls of the first connecting sleeve 21 and the second connecting sleeve 22 are slidably sleeved with the paper tube body 1. The opposite ends of the outer walls of the first connecting sleeve 21 and the second connecting sleeve 22 are respectively fixedly sleeved with the protective disc 23. The protective disc 23 is located at the end of the paper tube body 1. The docking assembly 24 is disposed between the first connecting sleeve 21 and the second connecting sleeve 22. The two protective discs 23 are installed at both ends of the paper tube body 1 through the first connecting sleeve 21, the second connecting sleeve 22, and the docking assembly 24, thereby binding the paper tube. The fibers wound on the outside of the paper tube 1 are restrained and fixed to prevent them from loosening and falling off from the end of the paper tube body 1. The protective disc 23 has multiple holes, which can reduce the manufacturing cost of the protective disc 23. The protective disc 23, the first connecting sleeve 21 and the second connecting sleeve 22 are all made of plastic. By cutting off the locking of the first connecting sleeve 21 and the second connecting sleeve 22 by the unconnecting assembly 24, the two protective discs 23, the first connecting sleeve 21 and the second connecting sleeve 22 can be removed from the paper tube body 1. The protective discs 23, the first connecting sleeve 21 and the second connecting sleeve 22 can be reused. In addition, the first connecting sleeve 21 and the second connecting sleeve 22 can also improve the compressive strength of the paper tube body 1.

[0025] In particular, the docking assembly 24 includes a first docking collar 241, a second docking collar 242, a connecting block 243, and a locking block 244. The first docking collar 241 and the second docking collar 242 are respectively fixedly connected to opposite ends of the first connecting sleeve 21 and the second connecting sleeve 22. The connecting block 243 and the locking block 244 are engaged between the first docking collar 241 and the second docking collar 242. The connecting block 243 is fixedly connected to one side of the second docking collar 242, and the locking block 244 is fixedly connected to one side of the connecting block 243. The first docking collar 241 has a connecting groove 245 on the side facing the second docking collar 242. The connecting block 243 is slidably sleeved on one side of the inner cavity of the connecting groove 245. A slot is provided on one side of the inner wall. The outer wall of the locking block 244 slides into the inner cavity of the slot. There are multiple connecting blocks 243 and locking blocks 244 at the end of the second docking collar 242, and they are arranged in a ring array. The width of the connecting groove 245 is greater than the distance between the opposite sides of the connecting blocks 243 and locking blocks 244. By rotating the second docking collar 242 relative to the first docking collar 241, the connecting blocks 243 can drive the locking blocks 244 to slide relative to the connecting groove 245. The connecting blocks 243 and locking blocks 244 slide into the connecting groove 245, so that the first docking collar 241 and the second docking collar 242 move in opposite directions, and the first connecting sleeve 21 and the second connecting sleeve 22 can be disassembled.

[0026] Furthermore, a connecting plate 246 is slidably disposed inside the first connecting sleeve 21. A positioning rod 247 is fixedly connected to one side of the connecting plate 246. Positioning holes are opened on one side of the first mating collar 241 and one side of the second mating collar 242. The outer wall of the positioning rod 247 is slidably sleeved with the inner cavity of the positioning hole. The positioning rod 247 can lock and limit the first mating collar 241 and the second mating collar 242, preventing the first mating collar 241 and the second mating collar 242 from rotating relative to each other. That is, when the positioning rod 247 is inserted and sleeved with the first mating collar 241 and the second mating collar 242, the locking block 244 is locked in the inner cavity of the slot, thereby ensuring the stability of the locking block 244 in the slot. A fixing plate 248 is fixedly connected inside the first mating collar 241. A fixing rod 249 is fixedly connected to one side of the 46. The outer wall of the fixing rod 249 is slidably inserted into the fixing plate 248. A limiting plate 2410 is fixedly connected to the end of the fixing rod 249. A limiting spring 2411 is slidably sleeved on the outer wall of the fixing rod 249. The limiting spring 2411 is located between the limiting plate 2410 and the fixing plate 248. The limiting spring 2411 can provide the connecting plate 246 with a spring force towards the first docking collar 241 through the limiting plate 2410 and the fixing rod 249, thereby ensuring the stability of the connecting plate 246 driving the positioning rod 247 to engage with the first docking collar 241 and the second docking collar 242. A handle is fixedly connected to the side of the connecting plate 246 away from the positioning rod 247, which facilitates the movement of the connecting plate 246 and the positioning rod 247.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
