Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chemical fiber winding paper tubes, in particular to a chemical fiber winding paper tube with an anti-slip surface. Background Art
[0002] Polyacrylonitrile precursor yarn is oiled during production. After being wound into a bobbin, the unwinding process can cause the entire roll to shift during carbon fiber production. This can cause the unwound tow to come off the roller surface, impacting carbon fiber production. Conventional paper tubes are designed with a speckled roller surface for anti-slip performance. This method only provides anti-slip performance for the first use and cannot be reused.
[0003] To this end, we have designed a chemical fiber winding paper tube with an anti-slip surface to solve the above problems. Utility Model Content
[0004] The purpose of the present invention is to provide a chemical fiber winding paper tube with a non-slip surface to solve the problems raised in the above background technology.
[0005] In order to solve the above technical problems, the utility model provides a chemical fiber winding paper tube with a non-slip surface, including a paper tube body, an anti-slip layer bonded to the outer surface of the paper tube body, a wire clip groove opened on the outer surface of the anti-slip layer, and an anti-slip strip clamped on the side wall of the wire clip groove.
[0006] Furthermore, the wire clamping groove is specifically a wave-shaped groove.
[0007] Furthermore, both ends of the paper tube body are threadedly connected with clamping rings.
[0008] Furthermore, both ends of the paper tube body are provided with external threads, and the inner wall of the clamping ring is provided with internal threads that match the external threads.
[0009] Furthermore, the side wall of the wire groove is fixedly connected with a fixing block, and the fixing blocks are distributed in a ring array on the side wall of the wire groove. The side wall of the anti-slip strip is provided with a limiting groove, and the fixing block is clamped in the limiting groove.
[0010] Furthermore, the anti-slip layer includes an epoxy primer layer, a high-strength fiber layer, and a polyurethane layer. The top of the epoxy primer layer is fixedly connected to the bottom of the high-strength fiber layer, and the top of the high-strength fiber layer is fixedly connected to the bottom of the polyurethane layer.
[0011] Compared with the prior art, the beneficial effects of the present invention are: by bonding an anti-slip layer to the outer surface of the paper tube body, the anti-slip and wear resistance of the paper tube are improved, so that the service life of the tube is extended, and a wire clamping groove is opened on the outer surface of the anti-slip layer, and the side wall of the wire clamping groove is fixedly connected to the anti-slip strip, which can increase the friction between the paper tube surface and the chemical fiber bundle, prevent the bundle from deviating during the winding and unwinding process, and improve the stability and production efficiency of the chemical fiber winding. This improved paper tube can be reused more than twice.
[0012] Compared with the prior art, the present invention has the following advantages: by providing the fixing block and the limiting groove, the anti-slip strip will not fall off during use, maintaining a stable anti-slip effect, and facilitating the replacement of the anti-slip strip. The filament bundle can also be further fixed by tightening the clamp ring. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] See also Figure 1-5The utility model provides a technical solution: a chemical fiber winding paper tube with an anti-slip surface, comprising a paper tube body 1, an anti-slip layer 3 bonded to the outer surface of the paper tube body 1, a wire clipping groove 4 opened on the outer surface of the anti-slip layer 3, and an anti-slip strip 5 clamped on the side wall of the wire clipping groove 4.
[0021] During implementation, the anti-slip layer 3 is evenly applied to the surface of the paper tube body 1 using an adhesive to improve the paper tube's anti-slip properties and wear resistance, thereby extending its service life. After drying, the paper tube is ready for use. The anti-slip strip 5 is then attached to the paper tube body 1 at the location corresponding to the wire retaining slot 4. This allows the wire tow to fit into the slot 4 during winding, enhancing its securement. The anti-slip strip 5 is securely attached to the sidewall of the slot 4, further increasing friction with the wire tow and ensuring that the wire tow does not shift during winding and unwinding.
[0022] See Figure 1-2 As shown, the wire groove 4 is specifically a wavy groove. This shape of groove can increase the contact area with the wire bundle, so that the wire bundle can be better embedded in the wire groove 4 during winding, thereby improving the fixing effect. At the same time, the wavy design also increases friction to prevent the wire bundle from sliding during unwinding.
[0023] See Figure 1-3 , both ends of the paper tube body 1 are threadedly connected with a clamping ring 2, which can further fix the wire bundle to prevent it from moving in the axial direction.
[0024] See Figure 1-3 External threads 6 are provided at both ends of the paper tube body 1, and internal threads 7 are provided on the inner wall of the clamping ring 2 to cooperate with the external threads 6. The external threads 6 and the internal threads 7 cooperate to achieve an adjustable connection with the paper tube body 1.
[0025] See Figure 1-4 The side wall of the wire groove 4 is fixedly connected with a fixing block 8, which is distributed in a ring array on the side wall of the wire groove 4. The side wall of the anti-slip strip 5 is provided with a limiting groove 9, and the fixing block 8 is clamped in the limiting groove 9. This connection method prevents the anti-slip strip 5 from falling off during use and maintains a stable anti-slip effect.
[0026] See Figure 5The anti-slip layer 3 includes an epoxy primer layer 301, a high-strength fiber layer 302, and a polyurethane layer 303. The top of the epoxy primer layer 301 is connected to the bottom of the high-strength fiber layer 302 by an adhesive. The top of the high-strength fiber layer 302 is also connected to the bottom of the polyurethane layer 303 by an adhesive. This bonding method ensures a tight bond between the layers. The epoxy primer layer 301 penetrates the tiny pores of the paper tube, forming a strong bond and preventing the anti-slip layer 3 from falling off during use. It also acts as a sealant, preventing moisture and other harmful substances from penetrating the paper tube and protecting its structural integrity. The high-strength fiber layer 302 possesses high strength and toughness. During the chemical fiber winding process, the paper tube is subjected to friction and tensile forces from the tow. The high-strength fiber layer 302 resists these external forces and prevents the anti-slip layer 3 from cracking or wearing. The polyurethane layer 303 provides anti-slip and chemical resistance. Tiny, evenly distributed dot-shaped protrusions on its surface are small enough not to damage the tow, but they prevent it from slipping. This ensures that the tow does not slip during winding and unwinding, maintaining good performance over long-term use.
[0027] Working principle: When in use, first use bonding to evenly apply the anti-slip layer 3 on the surface of the paper tube body 1. After it dries, it can be put into use, thereby improving the anti-slip and wear resistance of the paper tube and extending the service life of the tube. Then the anti-slip strip 5 is sleeved on the position corresponding to the wire groove 4 on the paper tube body 1. Since the wire groove 4 is specifically a wavy groove, this shape of groove can increase the contact area with the wire bundle, so that the wire bundle can be better embedded in the wire groove 4 during winding, thereby improving the fixing effect. At the same time, the wavy design also increases friction to prevent the wire bundle from sliding during unwinding. Then insert the fixing block 8 into the corresponding limit groove 9 to further fix the anti-slip strip 5. This connection method prevents the anti-slip strip 5 from falling off during use, maintaining a stable anti-slip effect. The wire bundle can also be further fixed by tightening the clamping ring 2.
