Description

Technical Field

[0001] The utility model belongs to the technical field of tube cores, and particularly relates to a self-cutting and quickly detachable tube core. Background Technique

[0002] The graphite paper tube core is a tubular structural member made mainly of graphite paper, and is usually used in applications such as heat conduction, electricity conduction, or high temperature resistance. The production process of the graphite paper tube core usually requires rolling the graphite paper into a cylindrical shape, and then fixing its shape by bonding or pressing to form a strong and lightweight tube core structure. The forming of the graphite paper is mainly completed by subjecting natural graphite flake raw materials to processes such as puffing, rolling, and winding to reach the target specifications. For the types of wound tube cores, there are mostly paper tube cores and plastic tube cores. Because the graphite paper formed by the above processes has more impurities, most of them still need to be subjected to high-temperature heat treatment to remove impurities and purify. Since the core is a paper tube or plastic tube that is not resistant to high temperatures, the tube core needs to be quickly taken out before purification.

[0003] Currently, there are two solutions for quickly taking out the tube core on the market: One solution is as shown in a trimming waste core device applied to the rewinding station of a large slitter, with the publication number CN212222028U. This core device fixes the core housing 1 through the chuck 3 and the elastic reset member 4, and the core housing 1 can be quickly taken out by removing the elastic reset member 4 and the chuck 3. However, this method is rather cumbersome and inconvenient when winding and removing the elastic reset member 4, and the efficiency is low; Another solution is as shown in the structure of the attached Figure 1 . A notch is opened on the cylindrical surface along the axial direction of the tube core, and a certain distance is reserved at both end faces. When the tube core needs to be extracted, the exposed tube core at both ends is cut off with a cutting machine or a utility knife, and it is ensured that the cut reaches the notch, so that the tube core inside the coil is separated into two halves. However, this method requires the use of additional cutting tools when cutting off the two ends of the tube core. When the cutting tools are lacking, the cutting work cannot be completed in time, and it is difficult to ensure that the cut is always flush with the end face during cutting, resulting in the inability to quickly and accurately cut to the notch during cutting. Therefore, in view of the above problems, it is of great significance to provide a self-cutting and quickly detachable tube core according to the utility model. Content of the Utility Model

[0004] The utility model provides a self-cutting type tube core that can be quickly withdrawn. Through a self-cutting component, the exposed parts at both ends of the tube core body can be cut off, so that the tube core body is separated into two halves, and thus the tube core body can be quickly taken out from the coil material. The whole process is convenient, fast and efficient. When the self-cutting component cuts the tube core body, it can not only ensure that the cut is always flush with the end face, so as to quickly and accurately cut to the notch during cutting, and no additional cutting tool is needed during cutting. After cutting and quickly taking out one tube core body, the self-cutting component can be installed at both ends of the next tube core body, so that the self-cutting component can be used cyclically for many times, avoiding waste. In summary, the problems in the background technology are solved.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] A self-cutting type tube core that can be quickly withdrawn according to the utility model includes a tube core body. The tube core body is cylindrical, and a notch is provided at both the top and the bottom thereof. A coil material is wound around the tube core body, and self-cutting components are provided at both ends of the tube core body.

[0007] The self-cutting component includes a self-cutting ring and a self-cutting knife. A knife groove is provided on the self-cutting ring, and the self-cutting knife is inserted into the knife groove.

[0008] Further, the notch is rectangular, and a certain distance is left between both ends thereof and the end faces of the tube core body. The notches are symmetrically distributed at the top and the bottom of the tube core body.

[0009] Further, the self-cutting ring is annular, and its inner diameter corresponds to and is equal to the outer diameter of the tube core body.

[0010] Further, both the self-cutting knife and the knife groove are L-shaped, and their widths correspond to and are equal to the width of the notch. The bottom of the self-cutting knife penetrates the bottom of the knife groove.

[0011] The utility model has the following beneficial effects compared with the prior art:

[0012] (1) When the self-cutting type tube core that can be quickly withdrawn in the utility model is in use, through the self-cutting component, the exposed parts at both ends of the tube core body can be cut off, so that the tube core body is separated into two halves, and thus the tube core body can be quickly taken out from the coil material. The whole process is convenient, fast and efficient.

[0013] (2) When the self-cutting type tube core that can be quickly withdrawn in the present utility model is in use, when the self-cutting component cuts the tube core body, not only can it ensure that the cut is always flush with the end face, so as to quickly and accurately cut to the notch during cutting, and no additional cutting tool is required during cutting. After cutting and quickly taking out one tube core body, the self-cutting component can be installed at both ends of the next tube core body, so that the self-cutting component can be used cyclically for multiple times, avoiding waste.

[0014] Of course, not necessarily all the advantages described above need to be achieved simultaneously for any product implementing the present utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] In the description of the present utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc. indicating the orientation or positional relationship are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0029] Please refer to Figures 1-9 As shown, a self-cutting and quickly detachable core of the present utility model includes a core body 1. The core body 1 is cylindrical, and a notch 2 is provided at both the top and bottom thereof. A coil material 3 is wound around the core body 1, and self-cutting components are provided at both ends of the core body 1;

[0030] The self-cutting component includes a self-cutting ring 4 and a self-cutting knife 5. A knife groove 6 is provided on the self-cutting ring 4, and the self-cutting knife 5 is inserted into the knife groove 6. Blades are provided on both sides of the self-cutting knife 5. When the self-cutting component is installed at both ends of the core body 1, by rotating the self-cutting ring 4, it can drive the self-cutting knife 5 to rotate along the circumferential direction of the core body 1 together. At this time, the exposed parts at both ends of the core body 1 can be cut off by the blades on both sides of the self-cutting knife 5, so that the core body 1 is separated into two halves, and thus the core body 1 can be quickly taken out from the coil material 3. By this cutting method, not only can it be ensured that the cut surface is always flush with the end face, so as to quickly and accurately cut to the notch 2 during cutting, and no additional cutting tool is required during cutting. After the cutting and quick removal of one core body 1 are completed, the self-cutting component can be installed at both ends of the next core body 1, so that the self-cutting component can be used repeatedly for multiple times, avoiding waste.

[0031] Among them, the notch 2 is rectangular, and a certain distance is left between both ends of the notch 2 and both end faces of the core body 1, and the notch 2 is symmetrically distributed at the top and bottom of the core body 1. When the coil material 3 is wound around the core body 1, the length of the notch 2 is greater than the width of the coil material 3.

[0032] Among them, the self-cutting ring 4 is annular, and its inner diameter corresponds to and is equal to the outer diameter of the tube core body 1. When the self-cutting assembly is installed at both ends of the tube core body 1, the self-cutting ring 4 can be attached to the outer walls at both ends of the tube core body 1.

[0033] Among them, both the self-cutting knife 5 and the knife groove 6 are L-shaped, and their widths correspond to and are equal to the width of the notch 2. Moreover, the bottom of the self-cutting knife 5 penetrates through the bottom of the knife groove 6. After the self-cutting knife 5 is inserted into the knife groove 6, it can be respectively attached to the inside of the knife groove 6 and the notch 2. When the self-cutting ring 4 is rotated, the self-cutting knife 5 can always be attached to one side of the notch 2, thereby ensuring that the cut is always flush with the end face during cutting, so as to quickly and accurately cut to the notch 2 during cutting.

[0034] The working principle of the present utility model is:

[0035] When the present utility model is in use, first wind the coil 3 around the tube core body 1, and then fix its shape by bonding or pressing to form a firm and lightweight graphite paper tube core structure. When it is necessary to remove impurities and purify the coil 3, sleeved the self-cutting ring 4 on both ends of the tube core body 1, then insert the self-cutting knives 5 into the knife grooves 6 on the two self-cutting rings 4 respectively, and make the knife grooves 6 fit into the knife grooves 6 and the notches 2 on the surface of the tube core body 1. Then hold the self-cutting rings 4 at both ends of the tube core body 1 and rotate them in the reverse direction, so that the self-cutting rings 4 in the two self-cutting assemblies at both ends drive the two self-cutting knives 5 to rotate in the reverse direction along the circumferential direction of the tube core body 1 together. At this time, the exposed parts at both ends of the tube core body 1 can be cut off by using the two side blades of the self-cutting knife 5, so that the tube core body 1 is separated into two halves. After that, the tube core body 1 can be quickly taken out from the coil 3. Through this cutting method, not only can it be ensured that the cut is always flush with the end face, so as to quickly and accurately cut to the notch 2 during cutting, but also no additional cutting tools are required during cutting. When the cutting of one tube core body 1 is completed and quickly taken out, the self-cutting assembly can be installed at both ends of the next tube core body 1, so that the self-cutting assembly can be used cyclically for many times, avoiding waste.
