Description

Technical Field

[0001] The utility model relates to the field of graphene heating wire processing, in particular to a graphene heating wire processing and forming mechanism. Background Art

[0002] Graphene, a two-dimensional material composed of a single layer of carbon atoms, possesses extremely high thermal conductivity and excellent electrical conductivity. When electricity is applied, the free electrons in graphene undergo irregular movement, a phenomenon known as Brownian motion. During this process, collisions between electrons and interactions with carbon atoms generate heat. This heat is generated by the collisions and friction between carbon atoms in the resistive layer.

[0003] The electric-to-heat conversion efficiency of graphene heating tubes is higher than that of the commonly used carbon fiber heating tubes. Therefore, more and more companies are researching related technologies of graphene heating tubes, such as a graphene film heating tube and a preparation method thereof disclosed in CN117915502A, and a graphene heating film and a heating device including the graphene heating film disclosed in CN208001380U, both of which involve heating wires with continuous bow-shaped distribution.

[0004] The above-mentioned bow-shaped heating wire is generally obtained by processing graphene sheets. Due to the fragility of the graphene sheets themselves, the automatic processing of graphene heating wires using traditional punching methods can easily lead to the breakage of the graphene sheets. Therefore, the applicant designed a graphene heating wire processing tool in "2024209773269". The tool cuts the graphene sheet through the action between the upper and lower tool holders that can bite into each other, directly forming the required heating wire shape.

[0005] After a period of production testing, the applicant found that this type of knife holder itself is difficult to process and has high replacement and maintenance costs. Therefore, in "2024224167551", a graphene heating wire pressing and cutting mechanism was designed, which uses a knife die and an upper pressure plate to directly press and cut the strip-shaped graphene sheet into a graphene heating wire; in order to protect the upper pressure plate and the blade, a movable buffer plate is added between the two, so that the same buffer plate can be used for a longer time, and when replacing it, only the buffer plate needs to be replaced.

[0006] However, after a period of research, it was found that the above solution still had problems such as slow efficiency in replacing the buffer plate and difficulty in mastering the timing of replacement.

[0007] Therefore, the inventor conducted further research and developed a graphene heating wire processing and molding mechanism, which resulted in the present case. Utility Model Content

[0008] The purpose of the utility model is to provide a graphene heating wire processing and forming mechanism, which further optimizes the structure of the buffer part on the basis of the original graphene heating wire pressing and cutting.

[0009] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0010] A graphene heating wire processing and forming mechanism, comprising

[0011] A mold, the upper surface of which is provided with a blade which is consistent with the shape of the product to be processed;

[0012] An upper pressing plate is located above the mold and can be raised and lowered relative to the mold;

[0013] The buffer film can move between the upper pressing plate and the blade through the winding parts on both sides.

[0014] In the original "2024224167551", the graphene sheet is processed into strips and then placed on the blade of the mold. The upper pressure plate presses down to form a graphene heating wire in the blade under the action of the buffer plate. Due to the presence of the blade, the buffer plate will also be damaged to a certain extent when under pressure. Therefore, the buffer plate has the function of translation relative to the upper pressure plate, so that when the buffer plate contacts the blade, after being acted upon by the blade multiple times at the same position, it will be translated and replaced, so that the same buffer plate can be used for a longer time, so that when it is replaced, only the buffer plate needs to be replaced.

[0015] However, in the above method, the buffer plate with a certain rigidity will inevitably change its center of gravity when moving, resulting in position deviation during pressing and cutting, and replacing the buffer plate is also more cumbersome and more costly; therefore, replacing the buffer plate with a buffer film that is retracted and released by the winding parts on both sides is more in line with actual production needs.

[0016] Furthermore, the buffer film is a PET film.

[0017] Furthermore, movable suction cups are provided on both sides of the mold, and the movable suction cups can move closer to or farther away from the mold.

[0018] Before the blade cuts, the mobile suction cup is used to absorb and fix the graphene sheet. After the blade cuts, the mobile suction cup sucks away the cut fragments on both sides.

[0019] Furthermore, the upper pressing plate is driven by a servo motor, a pneumatic device or a hydraulic device.

[0020] Furthermore, conveyor belts are provided on both sides of the mold and below the movable suction cup to receive graphene fragments that fall from the die.

[0021] After the mobile suction cup sucks and pulls out the fragments, it releases the suction on the fragments, and the fragments fall onto the conveyor belt below and are transported away by the conveyor belt.

[0022] Furthermore, the winding portion includes a winding roller, which is driven to rotate by a motor.

[0023] After adopting the above scheme, the utility model has the following advantages compared with the prior art:

[0024] Due to the properties of the buffer film, it can not only play a buffering role between the blade and the upper pressure plate, but also has the characteristics of being retractable and easy to rewind and replace, which is more economical than previous solutions.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figure 1 As shown, a graphene heating wire processing and molding mechanism includes a mold 3 and an upper pressing plate 1. The upper surface of the mold 3 is provided with a blade, which is consistent with the shape of the heating wire 7 of the product to be processed; the upper pressing plate 1 is located above the mold 3 and can be raised and lowered relative to the mold 3; a PET film 2 is provided between the upper pressing plate 1 and the mold 3, and the buffer film can move between the upper pressing plate 1 and the blade through the winding parts on both sides.

[0033] The winding section includes a winding roller 4 and a motor 5. When the motor 5 drives the winding roller 4 to rotate, the PET film 2 is unwound from the winding roller 4 on one side and wound on the winding roller 4 on the other side, thereby realizing the movement of the PET film 2, thereby realizing the movement function of the buffer plate in the prior patent.

[0034] At the same time, the properties of the PET film 2 itself determine that it can also play a buffering function between the blade and the upper pressing plate 1.

[0035] Therefore, it is only necessary to place a strip of graphene sheet of the appropriate width on the mold. Under the action of the upper pressing plate, the PET film 2 follows the upper pressing plate 1 to descend, and the PET film acts as a buffer when the blade cuts the graphene sheet.

[0036] As for the movable suction cups 8 set on both sides of the mold 3, their functions and structures are consistent with those of the prior patent. Conveyor belts 6 are also set on both sides of the mold 3 and below the movable suction cups. The conveyor belts 6 are used to receive the graphene fragments that fall from the knife mold. Before the blade cuts, the movable suction cups are used to adsorb and fix the graphene sheets. After the blade cuts, the movable suction cups suck away the cut fragments on both sides.

[0037] The upper pressing plate 1 only needs to have a stable drive to drive it upward and downward, and an existing driving device can be used.

[0038] The above-mentioned PET film is only a specific embodiment of the present invention. At the same time, all words such as "upper, lower, left, right, middle" involved in the present invention are for reference only and are not absolute limitations. Any non-substantial changes made using the present invention shall be deemed as an infringement of the protection scope of the present invention.
