Description

Technical Field

[0001] This utility model relates to the field of paper tube technology, and in particular to a wear-resistant chemical fiber paper tube. Background Technology

[0002] As a crucial industrial product, synthetic fiber paper tubes play a key role in the spinning, texturing, and winding processes of synthetic fibers. Made from base paper and specialized adhesives, they are manufactured using precision winding machines. Their applications are extensive, extending beyond the synthetic fiber industry to include packaging, printing, and many other sectors. In daily life, common products such as tea boxes, pen holders, and express delivery packaging all rely on synthetic fiber paper tubes, providing stable structural support for the winding of various items.

[0003] The working principle of chemical fiber paper tube winding is based on the mechanical operation of the tube winding machine. Pre-cut raw paper is fixed at one end to the rotating shaft of the winding machine. As the machine starts, the shaft rotates at a constant speed, driving the raw paper to wind around. Simultaneously, glue is precisely applied, allowing the paper layers to adhere tightly and gradually take shape. In terms of applications, in the chemical fiber industry, it serves as the "skeleton" for spinning and texturing winding, ensuring the neat winding of the yarns. In the packaging field, it transforms into the inner support of tea boxes and express delivery packaging, enhancing pressure resistance. It is also used in pen holder manufacturing, achieving a combination of creativity and practicality.

[0004] In existing technologies, the dimensions of fiber paper tubes processed by tube making machines are often fixed. When the required fiber paper tube size does not match the fixed processing size, additional cutting or splicing of the raw materials is required. Cutting results in the waste of excess material, while most splicing in existing technologies uses more glue and other auxiliary materials. Adding too much glue will affect product quality, and cutting leads to material waste. Therefore, a wear-resistant chemical fiber paper tube is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a wear-resistant chemical fiber paper tube, which aims to improve the problem that the size of the fiber paper tubes processed by the mechanical operation of the tube machine in the prior art is often fixed, which leads to various problems that cannot be adapted to different working conditions.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A wear-resistant chemical fiber paper tube includes a fiber outer layer, an engaging mechanism installed on the inner wall of the fiber outer layer, a protective mechanism installed on the outer wall of the fiber outer layer, an antistatic layer provided on the inner wall of the fiber outer layer, and a fixing ring fixedly connected to both the upper and lower ends of the antistatic layer.

[0008] The engaging mechanism includes a triangular block, a limiting plate is fixedly connected to the outer wall of the triangular block, a splicing groove is opened on the inner wall of the fiber outer layer, and another fiber outer layer is fixedly connected to the bottom of the triangular block.

[0009] The above technical solution allows for the following: when fiber paper tubes need to be spliced, the triangular block at the top of one fiber paper tube can be inserted into the splicing groove at the bottom of another fiber paper tube. At this time, the limiting plate on the outer wall of the triangular block can slide on the inner wall of the splicing groove, thereby firmly splicing the two fiber paper tubes with the limiting plate fixedly connected to the inner wall together, which is convenient for subsequent use. Moreover, this splicing method is simple to operate and the connection is stable.

[0010] As a further description of the above technical solution:

[0011] The protective mechanism includes a protective layer, the inner wall of which is detachably connected to the outer wall of the fiber outer layer, and double-sided adhesive is fixedly connected to the outer wall of the protective layer.

[0012] Through the above technical solution: the first protective layer is detachably connected to the outer wall of the fiber outer layer. When the fiber tube is not in use, it can protect the fiber tube and prevent it from falling to the ground and getting contaminated. The double-sided adhesive makes it easy to connect the second protective layer, so that the second protective layer can work with the first protective layer to better protect the fiber tube.

[0013] As a further description of the above technical solution:

[0014] A second protective layer is fixedly connected to the other side of the double-sided adhesive, and a tear-off edge is fixedly connected to the top of the second protective layer.

[0015] Through the above technical solution: the second protective layer is connected to the first protective layer with double-sided adhesive, which further enhances the protection effect on the fiber paper tube. When the fiber paper tube needs to be used, the second protective layer along with the double-sided adhesive can be torn off from the outside of the first protective layer by tearing the edge, thereby exposing the fiber paper tube for use. The tearing edge makes the tearing operation of the second protective layer convenient.

[0016] As a further description of the above technical solution:

[0017] The outer wall of the triangular block is slidably connected to the bottom inner wall of the outer fiber layer;

[0018] Through the above technical solution, the outer wall of the triangular block can slide on the inner wall at the bottom of the outer layer of the fiber, so that when splicing fiber paper tubes, the triangular block can be smoothly inserted into the splicing groove, ensuring the smoothness of splicing, and at the same time further improving the connection stability after splicing.

[0019] As a further description of the above technical solution:

[0020] One side of the outer wall of each of the two fixing rings is fixedly connected to the inner wall of the fiber outer layer, and the outer wall of the antistatic layer is provided with an adhesive layer;

[0021] The above technical solution involves fixing the antistatic layer to the inner wall of the fiber outer layer with a retaining ring, ensuring the stability of the antistatic layer's position. The adhesive layer is placed on the outer wall of the antistatic layer, which can firmly bond the antistatic layer to other layers, making the entire paper tube structure more stable. At the same time, the good bonding performance and weather resistance of the adhesive layer allow the paper tube to be used under different environmental conditions.

[0022] As a further description of the above technical solution:

[0023] An inner layer is provided on the outside of the adhesive layer;

[0024] Through the above technical solution: the adhesive layer bonds the inner layer and the antistatic layer together. The inner layer is made of polycarbonate, which has good mechanical properties, including high strength, toughness and impact resistance. It can absorb external impact to a certain extent and protect the paper tube from damage. The presence of the adhesive layer makes the inner layer and the antistatic layer tightly bonded, improving the overall performance of the paper tube.

[0025] As a further description of the above technical solution:

[0026] The outer wall of the limiting plate is slidably connected to the inner wall of the splicing groove;

[0027] Through the above technical solution, the outer wall of the limiting plate slides on the inner wall of the splicing groove, so that when the two fiber paper tubes are spliced, the limiting plate can play a further limiting and fixing role, preventing the spliced ​​fiber paper tubes from loosening or misaligning, thereby ensuring the splicing firmness and improving the stability of the fiber paper tubes during use.

[0028] As a further description of the above technical solution:

[0029] The bottom of the outer fiber layer is detachably connected to the top of the other outer fiber layer, and the inner sides of both retaining rings are fixedly connected to the outer wall of the inner layer.

[0030] The above technical solution allows for the detachable connection between the bottom of the outer fiber layer and the top of another outer fiber layer, facilitating the splicing and disassembly of the fiber paper tube. It also allows for flexible operation when the length of the fiber paper tube needs to be changed. The inner side of the fixing ring is fixedly connected to the outer wall of the inner layer, further strengthening the connection between the inner layer, the antistatic layer, and the outer fiber layer. This makes the structure of the entire paper tube more stable and improves its durability and practicality.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, the triangular block at the top of one fiber paper tube is inserted into the splicing groove at the bottom of another fiber paper tube. The triangular block causes the limiting plate on its outer wall to slide on the inner wall of the splicing groove, thereby fixing the two inner walls together with the limiting plate and splicing them together firmly. This allows the length of the fiber paper tube to be adjusted according to the actual situation, so that the fiber paper tube can adapt to different working conditions and facilitate subsequent use.

[0033] 2. In this utility model, the possibility of the outer layer of the fiber paper tube coming into contact with the outside world is reduced by adding a protective mechanism, so that the fiber paper tube will not be contaminated with dirt when not in use, thus affecting its subsequent use. The use of polyester fiber outer layer improves the overall wear resistance of the fiber paper tube, thereby greatly extending its service life. The use of carbon fiber as an antistatic layer can effectively prevent dust and other fine particles from being adsorbed to the outside of the fiber paper tube through electrostatic action.

[0040] 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.

[0041] Reference Figure 1 , Figure 3 and Figure 4A wear-resistant chemical fiber paper tube includes a fiber outer layer 1. The fiber outer layer 1 is made of polyester fiber, which has high strength and wear resistance, is not easily worn or torn, and can effectively protect the paper tube from external friction and scratches. The inner wall of the fiber outer layer 1 is equipped with a locking mechanism 7. After the fiber paper tube is disassembled, it can be spliced ​​according to the actual situation. The locking mechanism 7 facilitates the splicing of two fiber paper tubes. At this time, the triangular block 71 at the top of one fiber paper tube is inserted into the splicing groove 73 at the bottom of the other fiber paper tube. The triangular block 71 will cause the limiting plate 72 on its outer wall to slide on the inner wall of the splicing groove 73, so that the two inner walls are fixedly connected and the limiting plate 72 is firmly spliced ​​together, which is convenient for subsequent use.

[0042] The outer wall of the fiber outer layer 1 is equipped with a protective mechanism 2. The function of the first protective layer 21 and the second protective layer 24 is to protect the fiber paper tube when it is not in use, preventing it from falling to the ground and becoming contaminated. The protective mechanism 2 can protect the fiber paper tube. The inner wall of the fiber outer layer 1 is provided with an antistatic layer 3. The antistatic layer 3 can effectively prevent the accumulation of static electricity and protect the fiber paper tube. The antistatic layer 3 is made of carbon fiber, which has good conductivity and high strength and can quickly conduct charge, effectively preventing the accumulation of static electricity. The upper and lower ends of the antistatic layer 3 are fixedly connected with fixing rings 6. The fixing rings 6 can fix the antistatic layer 3 and make its position more stable.

[0043] The locking mechanism 7 includes a triangular block 71. A limiting plate 72 is fixedly connected to the outer wall of the triangular block 71. The limiting plate 72 can cooperate with the splicing groove 73 during splicing to make the connection between the two fiber paper tubes more secure. The inner wall of the fiber outer layer 1 is provided with a splicing groove 73. The splicing groove 73 can cooperate with the triangular block 71 to realize the splicing of the two fiber paper tubes. Another fiber outer layer 1 is fixedly connected to the bottom of the triangular block 71. The triangular block 71 is used to connect the two fiber outer layers 1. The outer wall of the triangular block 71 is slidably connected to the bottom inner wall of the fiber outer layer 1. The slidable connection of the triangular block 71 can facilitate splicing.

[0044] One side of the outer wall of each of the two fixing rings 6 is fixedly connected to the inner wall of the fiber outer layer 1. The fixing rings 6 can fix the antistatic layer 3 to the inner wall of the fiber outer layer 1. The outer wall of the antistatic layer 3 is provided with an adhesive layer 4, which can play a bonding role, connecting the antistatic layer 3 and the inner layer 5 together. The adhesive layer 4 is made of acrylic resin, which has good adhesion and weather resistance, fast curing speed, and can be used under different environmental conditions. The outer wall of the limiting plate 72 is slidably connected to the inner wall of the splicing groove 73. The sliding of the limiting plate 72 on the inner wall of the splicing groove 73 can realize the splicing and fixing of the two fiber paper tubes. The bottom of the fiber outer layer 1 can be detachably connected to the top of another fiber outer layer 1, which is convenient for splicing and disassembling the fiber paper tubes. The inner sides of the two fixing rings 6 are fixedly connected to the outer wall of the inner layer 5. The fixing rings 6 can fix the inner layer 5 and make its position stable.

[0045] Specifically, the outer fiber layer 1 is made of polyester fiber, which is wear-resistant and abrasion-resistant. Its inner wall locking mechanism 7 includes a triangular block 71, a limiting plate 72, and a splicing groove 73, which facilitates the splicing of the fiber paper tube according to the actual situation after disassembly, ensuring subsequent use. The outer wall protection mechanism 2 has protective layers 21 and 2 to prevent the fiber paper tube from being contaminated when it falls to the ground. The antistatic layer 3 is made of carbon fiber, and the upper and lower fixing rings 6 stabilize its position and prevent static electricity accumulation. The adhesive layer 4 is acrylic glue, which bonds the antistatic layer 3 to the inner layer 5. The inner layer 5 is polycarbonate, which has good mechanical properties. All the structures work together to provide multi-directional protection for the fiber paper tube.

[0046] Reference Figures 1 to 3 The protective mechanism 2 includes a first protective layer 21. The inner wall of the first protective layer 21 is detachably connected to the outer wall of the outer fiber layer 1. When the fiber paper tube needs to be used, the second protective layer 24, along with the double-sided adhesive 23, is torn off from the outside of the first protective layer 21 via the tear edge 22, making it easier to expose the fiber paper tube for use. The first protective layer 21 can protect the fiber paper tube. The outer wall of the first protective layer 21 is fixedly connected with the double-sided adhesive 23, which is used to connect the first protective layer 21 and the second protective layer 24. The other side of the double-sided adhesive 23 is fixedly connected to the second protective layer 24. 24 can cooperate with protective layer 1 21 to protect the fiber paper tube when it is not in use. The top of protective layer 24 is fixedly connected with tear edge 22, which makes it easy to tear protective layer 24 off protective layer 1 21. An inner layer 5 is provided on the outside of adhesive layer 4. The inner layer 5 can provide a certain degree of protection and support for the fiber paper tube. The material of the inner layer 5 is polycarbonate. Polycarbonate has good mechanical properties, including high strength, toughness and impact resistance. The inner ring of polycarbonate material can absorb external impact to a certain extent and protect the fiber paper tube from damage.

[0047] Specifically, the inner wall of the protective layer 21 is detachably connected to the outer wall of the fiber outer layer 1. When the fiber paper tube is not in use, it can provide protection. Its outer wall double-sided adhesive 23 connects to the protective layer 24. The top tear edge 22 of the protective layer 24 is cleverly designed. When the fiber paper tube is in use, the protective layer 24 can be easily torn off through the tear edge 22. In addition, the inner layer 5 outside the adhesive layer 4 is made of polycarbonate material, which provides strong protection and support to the fiber paper tube with its excellent mechanical properties.

[0048] Working principle: After the fiber paper tubes are disassembled, they can be spliced ​​together according to the actual situation. At this time, the triangular block 71 at the top of one fiber paper tube is inserted into the splicing groove 73 at the bottom of the other fiber paper tube. The triangular block 71 will cause the limiting plate 72 on its outer wall to slide on the inner wall of the splicing groove 73, so that the two inner walls are fixedly connected and firmly spliced ​​together by the limiting plate 72, which is convenient for subsequent use.

[0049] When the fiber paper tube needs to be used, the second protective layer 24, along with the double-sided adhesive 23, is torn off from the outside of the first protective layer 21 by tearing the edge 22, so that the fiber paper tube can be exposed for use. At the same time, the function of the first protective layer 21 and the second protective layer 24 is to protect the fiber paper tube when it is not in use, so as to prevent it from falling to the ground and being contaminated.

[0050] The outer fiber layer 1 is made of polyester fiber, which has high strength and wear resistance, is not easily worn or torn, and can effectively protect the paper tube from external friction and scratches. The antistatic layer 3 is made of carbon fiber, which has good conductivity and high strength, can quickly conduct charges, and effectively prevent static electricity accumulation. The adhesive layer 4 is made of acrylic resin, which has good adhesion and weather resistance, and cures quickly, making it suitable for use in different environmental conditions. The inner layer 5 is made of polycarbonate, which has good mechanical properties, including high strength, toughness and impact resistance. The inner ring of polycarbonate can absorb external impacts to a certain extent and protect the paper tube from damage.
