Description

Technical Field

[0001] The utility model belongs to the technical field of chemical fiber paper tubes, and in particular relates to high-toughness chemical fiber paper tubes. Background Art

[0002] Chemical fiber paper tubes are paper tubes used for winding chemical fibers, spinning, and stretching. Chemical fiber paper tubes are generally formed by winding and pasting multiple layers of paper. The processing involves processes such as compounding, winding, curing, and cutting. During the use of chemical fiber paper tubes in the textile industry, the deformation, surface smoothness and other properties of chemical fiber paper tubes directly affect the normal operation of production processes such as spinning. Existing chemical fiber paper tubes have poor toughness. Once the silk thread is wrapped around the paper tube (the silk thread sometimes weighs 2-3 kilograms), it is easy to deform when the force on various parts is uneven during the production process, and it cannot recover automatically. As a result, the number of times the paper tube is recycled is small, and the overall service life is not long. Utility Model Content

[0012] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0013] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0014] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0015] like Figure 1-2As shown, the high-toughness chemical fiber paper tube includes an inner paper tube 1, an outer paper tube 2 and a core paper tube 3. The inner paper tube 1 and the outer paper tube 2 are coaxially arranged. The core paper tube 3 is sandwiched between the inner paper tube 1 and the outer paper tube 2. The inner surface of the inner paper tube 1 is provided with a wear-resistant layer, and the outer surface of the outer paper tube 2 is provided with a smooth layer. The core paper tube 3 is formed by winding multiple layers of paper. The multiple layers of paper include an inner ordinary paper layer 4, an inner cotton layer 5, a mesh layer 6, an outer cotton layer 7 and an outer ordinary paper layer 8 bonded by glue in sequence. The inner paper tube 1 is bonded to the core paper tube 3 by glue, and the outer paper tube 2 is bonded to the core paper tube 3 by glue. The surface of the outer paper tube 2 is smooth and will not affect the high-speed spinning process. The inner paper tube 1 is wear-resistant inside and will not slip when installed on the spinning equipment. The core paper tube 3 has good toughness, a certain elastic deformation ability, and good bonding between each other.

[0016] Furthermore, the mesh layer 6 is woven from nylon threads. Nylon threads are high in strength, good in toughness, and easy to bend and wind. The mesh layer 6 woven from the middle nylon threads can effectively improve the overall toughness of the chemical fiber paper tube, and can transfer the local force of the chemical fiber paper tube to the whole, making it less likely to deform.

[0017] Furthermore, the inner cotton layer 5 and the outer cotton layer 7 are respectively made of natural cotton.

[0018] Furthermore, the thickness of the inner cotton layer 5 and the thickness of the outer cotton layer 7 are 1-3 mm respectively. The inner cotton layer 5 and the outer cotton layer 7 can contact each other through the mesh and be connected as a whole by glue, so that the mesh layer 6 is sandwiched in the middle. By utilizing the thickness of the inner cotton layer 5 and the fibers on the outer cotton layer 7, the bonding force of each layer is improved, the structural strength of the paper tube as a whole is improved, and the paper tube is more tensile-resistant.

[0019] Furthermore, the grids on the grid layer 6 are in a rhombus shape. The four corners of the rhombus grids are tightened and have a certain toughness, thereby improving the toughness of the entire chemical fiber paper tube.

[0020] Furthermore, the inner paper tube 1 and the outer paper tube 2 are respectively formed by bonding kraft paper end to end, the wear-resistant layer is composed of a wear-resistant coating applied on the inner surface of the inner paper tube 1, and the smooth layer is composed of a smooth coating applied on the outer surface of the outer paper tube 2. The wear-resistant coating and the smooth coating can be commercially available products, or they can be configured by themselves according to the disclosed technology. For example, the wear-resistant coating can be made of a high molecular polymer (polyurethane) added with an adhesive (epoxy resin) and an inorganic filler (silicon dioxide) in a certain ratio (5:1:1). The smooth coating can also be formed by a release film (PET) adhered to the outer surface of the outer paper tube 2.

[0021] It is worth mentioning that the technical features such as glue, wear-resistant coating, smooth coating, etc. involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected according to the conventional methods in the field, and should not be regarded as the invention point of this utility model patent. This utility model patent will not be further elaborated.

[0022] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field through logical analysis, reasoning or limited experiments based on the concept of the utility model on the basis of the existing technology should be within the scope of protection determined by the claims.
