Description

Technical Field

[0001] The utility model belongs to the technical field of tube cores, and particularly relates to a socket-type tube core that can be quickly withdrawn. Background Technique

[0002] Graphite paper is an interfacial material with special properties, which is mainly made of graphite particles through special processing. Due to its unique physical and chemical properties, graphite paper is widely used in many fields such as sealing, energy storage, and photovoltaic fields. The forming of graphite paper mainly completes the target specifications through processes such as expanding, rolling, and coiling of natural graphite flake raw materials. For the types of tube cores for coiling, there are mostly paper tube cores and plastic tube cores. Because the impurities in the graphite paper coiled by the above processes are relatively many, most of them still need to be purified by high-temperature heat treatment to remove impurities. Since the tube core is a paper tube or plastic tube that is not resistant to high temperature, the tube core needs to be quickly taken out before purification.

[0003] At present, there are some tube core structures on the market. For example, a trimming waste core device applied to the rewinding station of a large slitter is disclosed on the Chinese Patent Network, and its publication number is CN212222028U. This core device uses an air inflation structure, so that the trimming waste rewound by the slitter can be loosened by exhausting air, thus facilitating removal from the core, reducing the process time of the large slitter, reducing the labor intensity of operators, and improving work efficiency. However, there are some defects and deficiencies to be improved: (1) It is necessary to fix and join the tube core through elastic components such as tapes, which is relatively cumbersome. And when taking out the tube core, it is necessary to use tools such as scissors to cut the elastic components such as tapes to separate and take out the tube core, which is relatively inconvenient; (2) When fixing and joining the tube core, there are no effective limiting measures, so that the tube core is prone to deviation and dislocation at the end face after joining. Therefore, in view of the above problems, it is of great significance to provide a socket-type tube core that can be quickly withdrawn according to the utility model. Summary of the Utility Model

[0004] The utility model provides a socket-type tube core that can be quickly withdrawn. The end caps can be used to fix and join a pair of tube core bodies without using elastic components such as tapes, and the tube core can be taken out without using tools such as scissors to cut the elastic components such as tapes, so that the process of fixing and taking out the tube core is more convenient and fast; the card slots on the surface of the end caps can play a limiting role, thus effectively avoiding the deviation and dislocation of a pair of tube core bodies at the end face after joining. In summary, the problems in the background technique are solved.

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

[0006] A socket-type tube core that can be quickly withdrawn according to the present utility model includes a pair of tube core bodies. The cross-section of the tube core body is semi-circular. The lengths, inner diameters, and outer diameters of the two tube core bodies are correspondingly equal. A material roll is wound around the tube core body. End caps are installed at both ends of the tube core body. A pair of card slots are opened at one end of the end cap, and a through hole is opened at the center of the end cap.

[0007] Further, the card slot is arc-shaped, and the inner and outer diameters of the card slot correspond to the inner and outer diameters of the tube core body.

[0008] The present utility model has the following beneficial effects compared with the prior art:

[0009] (1) When the socket-type tube core that can be quickly withdrawn according to the present utility model is in use, the pair of tube core bodies can be fixed and spliced through the end cap, without using elastic components such as tapes, and the tube core can be taken out without using tools such as scissors to cut the elastic components such as tapes, so that the fixing and taking-out processes of the tube core are more convenient and fast;

[0010] (2) When the socket-type tube core that can be quickly withdrawn according to the present utility model is in use, the card slot on the surface of the end cap can play a role in limiting, thus effectively avoiding the offset and dislocation of the end faces of the pair of tube core bodies after splicing.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to 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 of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0020] 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 cannot be understood as a limitation to the present utility model.

[0021] Please refer to Figures 1-4 As shown, a socket-type and quickly detachable core of the present utility model includes a pair of core bodies 1. The cross-section of the core body 1 is semi-circular. The lengths, inner and outer diameters of the two core bodies correspond to each other and are equal. And a material roll 2 is wound on the core body 1. The material roll 2 is made of graphite paper material. After the material roll 2 is wound on the core body 1, the material roll 2 can be supported by the core body 1. End caps 3 are installed at both ends of the core body 1. A pair of card slots 4 are opened at one end of the end cap 3, and a through hole is opened at the center of the end cap 3. Both ends of the air shaft can pass through the through hole at the center of the end cap 3 and be in close fit with the core body 1; The air shaft is a special winding and unwinding shaft, which is widely used in various mechanical equipment that requires winding or unwinding materials; Through high-pressure inflation, the surface of the air shaft can quickly protrude, so as to tightly bite the external components; Realize the functions of winding or unwinding; After deflation, its surface part can quickly retract, which is convenient for replacing or removing external components. It belongs to the prior art, and its specific structure and principle are not the protection points of this technical solution, and the structure and principle thereof will not be described in detail in this specification.

[0022] Among them, the card slot 4 is arc-shaped, and the inner and outer diameters of the card slot 4 correspond to and are equal to the inner and outer diameters of the core body 1. The arc length of the card slot 4 is slightly greater than that of the core body 1. As long as the depth of the card slot 4 can ensure that the core body 1 is stably clamped and not easily detached after insertion, it belongs to the protection scope of this technical solution. For example, in this technical solution, the depth of the card slot 4 can be selected as 1 / 6 of the diameter length of the end cap 3. Of course, other forms and dimensions that meet the requirement of not being easily detached by clamping belong to the protection scope of this technical solution. The centers of a pair of card slots 4 correspond to the centers of a pair of core bodies 1 for easy installation. When the end caps 3 are attached to both ends of the core body 1, a pair of core bodies 1 can be respectively aligned and inserted into the corresponding card slots 4. At this time, the end caps 3 can fix and join a pair of core bodies 1 without using elastic components such as tapes. And because the core body 1 can be inserted and attached to the inner wall of the card slot 4, the card slot 4 can play a role in limiting the position, thus effectively avoiding the offset and dislocation of the end faces of a pair of core bodies 1 after splicing. When it is necessary to take out the core body 1, the end caps 3 are removed from both ends of the core body 1. At this time, a pair of core bodies 1 can be naturally separated, and then the core body 1 can be pulled out from the wound material roll 2 without using tools such as scissors to cut the elastic components such as tapes, making the fixing and taking-out processes of the core more convenient and fast.

[0023] The working principle of the present utility model is:

[0024] When the present utility model is in use, first, the air shaft is installed into the core body 1. Then, the end caps 3 can be respectively attached to both ends of a pair of core bodies 1, and a pair of core bodies 1 are respectively aligned and inserted into the corresponding card slots 4. At this time, the end caps 3 can fix and join a pair of core bodies 1 without using elastic components such as tapes. And because the core body 1 can be inserted and attached to the inner wall of the card slot 4, the card slot 4 can play a role in limiting the position, thus effectively avoiding the offset and dislocation of the end faces of a pair of core bodies 1 after splicing. After a pair of core bodies 1 are spliced, the air shaft is inflated to make it closely fit with the core body 1, and the material roll 2 is wound around the core body 1. At this time, the material roll 2 can be supported by the core body 1. When it is necessary to remove impurities and purify the material roll 2, the air shaft is deflated, the air shaft is pulled out, and the end caps 3 are removed from both ends of the core body 1. At this time, a pair of core bodies 1 can be naturally separated, and then the core body 1 is pulled out from the wound material roll 2, and the material roll 2 can be separately subjected to high-temperature heat treatment to remove impurities and purify without using tools such as scissors to cut the elastic components such as tapes, making the fixing and taking-out processes of the core more convenient and fast.
