Description

Technical Field

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

[0002] Graphene is a two-dimensional material composed of a single layer of carbon atoms, with extremely high thermal conductivity and excellent electrical conductivity. When powered on, the free electrons in graphene move irregularly under the action of an electric current, a phenomenon known as Brownian motion. During this process, the collisions between electrons and the interactions between electrons and carbon atoms generate heat, which is produced by the mutual collisions and frictions of carbon atoms in the resistance layer.

[0003] The electrothermal conversion efficiency of graphene heating tubes is higher than that of commonly used carbon fiber heating tubes at present. Therefore, more and more enterprises are researching related technologies of graphene heating tubes. For example, a graphene film heating tube and its preparation method 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 distributed in a continuous bow shape.

[0004] The above-mentioned bow-shaped heating wires are generally obtained by processing graphene sheets. Due to the fragility of graphene sheets themselves, the automatic processing of graphene heating wires using traditional punching methods is likely to cause the fragmentation of graphene sheets. Therefore, the applicant designed a graphene heating wire processing tool in "2024209773269", which cuts graphene sheets through the interaction between two mutually engaging tool holders above and below to directly form the required shape of the heating wire.

[0005] However, after a period of production tests, the applicant found that the processing of this type of tool holder itself is relatively difficult, and the replacement and maintenance costs are high. Therefore, based on the previous research, a graphene heating wire pressing and cutting mechanism was developed, and this case was thus generated. Content of the Utility Model

[0006] The purpose of the utility model is to provide a graphene heating wire pressing and cutting mechanism, which can reduce the production difficulty and cost of graphene heating wire processing equipment and reduce its maintenance cost.

[0007] To achieve the above purpose, the technical solution of the utility model is as follows:

[0008] A graphene heating wire pressing and cutting mechanism includes

[0009] a base, on which a mold is provided, and a cutting edge is provided on the upper surface of the mold, and the cutting edge is consistent with the outer shape of the product to be processed;

[0010] An upper pressing plate is located above the mold and can be raised and lowered relative to the mold;

[0011] The buffer plate is arranged below the upper pressing plate and can rise and fall with the upper pressing plate, and can also move horizontally relative to the upper pressing plate.

[0012] After the graphene sheet is processed into strips, it is placed on the blade of the mold. The upper pressure plate presses down, so that the graphene sheet forms a graphene heating wire in the blade under the action of the buffer plate. Due to the existence 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. When the buffer plate is in contact with the blade, after being acted on 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, and when replaced, only the buffer plate needs to be replaced.

[0013] 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.

[0014] 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.

[0015] Furthermore, the upper pressing plate is driven by a pneumatic / hydraulic cylinder.

[0016] 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.

[0017] 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.

[0018] Furthermore, the left and right sides of the buffer plate are arranged in the bracket, the bracket is driven to move horizontally by the servo motor, and the bracket and the servo motor can both rise and fall along with the upper pressure plate.

[0019] After adopting the above scheme, the utility model has the following advantages compared with the prior art:

[0020] The cost of the graphene heating wire processing device is reduced, making its production difficulty and maintenance cost lower, and making it more convenient for industrial production. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Label description

[0026] Upper pressure plate 1, buffer plate 2, base 3, mold 4, servo motor 5,

[0027] Slide block 6, bracket 7, negative pressure device 8, adsorption hole 9,

[0028] Conveyor belt 10, hydraulic device 11, graphene sheet 12, Specific implementation mode

[0029] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] In this embodiment, the graphene heating wire refers to the state without electrodes installed at both ends.

[0031] As Figure 1 shown, a cutting mechanism for graphene heating wires includes an upper pressure plate 1, a buffer plate 2, a base 3, and a mold 4. Four columns are arranged around the base 3, and a hydraulic device 11 is arranged on the columns. The bottom of the hydraulic device 11 is the upper pressure plate 1, and the upper pressure plate 1 can be lifted and lowered under the drive of the hydraulic device 11.

[0032] On both sides of the upper pressure plate 1, a servo motor 5 is arranged respectively. The servo motor 5 drives a lead screw to rotate, so that the slide block 6 arranged on the lead screw moves accordingly; and the aforementioned buffer plate 2 is located on the lower surface of the upper pressure plate 1, and both sides of it are embedded in the bracket 7. The bracket 7 is linked with the slide block 6. Through the drive of the servo motor 5, the buffer plate 2 can move horizontally relative to the upper pressure plate 1, and vertically, the buffer plate 2 rises and falls together with the upper pressure plate 1.

[0033] The mold 4 is arranged below the buffer plate 2, and a cutting edge is arranged on its upper surface. The shape formed by the overall cutting edge is the shape of the graphene heating wire. That is, after the graphene sheet 12 is placed on the cutting edge, when the buffer plate 2 above presses down, the cutting edge directly cuts the graphene sheet 12 to form a graphene heating wire. In order to prevent the graphene heating wire from moving during cutting, a negative pressure device 8 can be arranged at both ends or on both sides of the mold 4. When the negative pressure device 8 is arranged on both sides of the mold 4, the length of the negative pressure device 8 is greater than or equal to the length of the graphene sheet 12. A number of adsorption holes 9 are opened on its upper surface, and a number of through holes communicating with the negative pressure cylinder are arranged on the side. At the same time, a slide rail is arranged at the bottom of the negative pressure device 8, and the negative pressure device 8 can translate on the slide rail in a direction perpendicular to the mold 4; that is, the negative pressure device 8 not only needs to play a role in fixing the graphene sheet 12, but also needs to suck away the unnecessary graphene fragments from around the graphene heating wire after cutting is completed.

[0034] For the cleaning of the debris sucked away by the negative pressure device 8, a circulating conveyor belt 10 is arranged below the negative pressure device 8. When the negative pressure device 8 moves and the suction is removed, the debris will fall onto the conveyor belt 10 below, thus preventing the debris from accumulating on the base 3.

[0035] After the buffer plate 2 presses the blade at the same position multiple times, it can be translated by driving the servo motor 5 to change the contact position with the blade. When all the contact positions that can contact the blade are used up, the buffer plate 2 can be disassembled and replaced separately.

[0036] The above are only specific embodiments of the present invention. At the same time, words such as "upper, lower, left, right, middle" involved in the present invention are only for reference and are not absolutely limited. Any non-substantive modification using the present invention shall fall within the scope of infringement of the protection scope of the present invention.
