Abstract
Description
Technical Field
[0001] This utility model relates to the field of graphene electrothermal film technology, specifically to a cutting device for the production of graphene electrothermal film. Background Technology
[0002] Graphene heating films need to be cut to specific dimensions during production, requiring a corresponding cutting device. Common cutting processes involve manually moving the graphene heating film to the cutting area, resulting in low processing efficiency. To address this issue, existing technology, such as the utility model patent with publication number CN217626750U, discloses a cutting device for graphene heating film production. This device includes two sets of drive shafts, a limiting block and a cutting mechanism positioned between the two sets of drive shafts. The limiting block has a material passage hole in its center, and electromagnets and pressure plates are correspondingly arranged on the upper and lower inner walls of the limiting plate. During operation, the graphene heating film passes between the two first drive shafts, inside the material passage hole of the limiting plate, and between the second drive shaft. When cutting is required, an electric push rod pushes the limiting block to the cutting position, and a hydraulic cylinder drives the cutting blade downwards to perform the cutting.
[0003] While the above technical solution replaces manual movement of the graphene heating film to some extent, it still presents certain operational difficulties for the flexible graphene heating film to pass smoothly through the central material passage of the limiting block without external force after passing through the first drive shaft. Slight carelessness may even cause damage to the heating film. Therefore, when processing the flexible graphene heating film, the end of the heating film still requires manual assistance during the journey from the first drive shaft to the limiting block, which is not conducive to the full automation of the production and processing of flexible graphene heating films. Utility Model Content

The middle of the crank arm is hinged to the connecting frame. The other end of the crank arm is hinged to one end of the connecting rod.

[0015] Furthermore, a hot pressing mechanism is provided on the input side of the pressing mechanism.
[0016] Furthermore, a conveyor belt with the same direction as the production line is provided below the clamping mechanism to transport the cut graphene electrothermal film to the next process.

[0025] The principles and features of this utility model are described below. The embodiments given are only used to explain this utility model and are not intended to limit the scope of this utility model.
[0026] As shown in the attached figure, this embodiment provides a cutting device for the production of graphene electrothermal film, which includes a first slide rail 1 in the same direction as the production line and a first slider 2 slidably connected to the first slide rail 1. It also includes a second slide rail 3 perpendicular to the direction of the production line and a second slider 4 slidably connected to the second slide rail 3. The first slider 2 is driven by a driving source to perform linear reciprocating motion on the first slide rail 1, and the first slider 4 is driven by a driving source to perform linear reciprocating motion on the second slide rail 3. Such driving sources are existing technologies and will not be described in detail here.
[0027] In this embodiment, the input side of the cutting mechanism 6 is also provided with a pressing mechanism 7. The pressing mechanism 7 includes a base plate 71 and a pressure plate 72 that can move up and down relative to the base plate 71. The pressure plate 72 is connected to a lifting drive 62 for driving its up and down movement, which can be a cylinder or an electric push rod.
[0028] The first slider 2 is connected to a clamping mechanism 5 via a mounting base 55. A cutting mechanism 6 is provided on the input side of the clamping mechanism 5, and the cutting mechanism 6 is connected to the second slider 4.
[0029] The clamping mechanism 5 includes a connecting frame 51, a crank arm 52, a connecting rod 53, and a clamping drive 54. The clamping drive 54 is existing technology and can be in the form of a cylinder or an electric push rod. The connecting frame 51 is fixed on the mounting base 55. The crank arms 52 are arranged symmetrically in a vertical arrangement, and the connecting rods 53 are arranged symmetrically in a vertical arrangement. The end of the crank arm 52 near the cutting mechanism 6 is a straight section 521. The middle part of the crank arm 52 is hinged to the connecting frame 51. The other end of the crank arm 52 is hinged to one end of the connecting rod 53. The other end of the connecting rod 53 is hinged to the connecting block 541 fixed to the telescopic end of the clamping drive 54. The extension and retraction of the clamping drive 54 controls the opening and closing of the straight section 521 at the front end of the two crank arms 52. In the closed state, it is used to clamp the graphene electrothermal film, and in the open state, it is used to release the graphene electrothermal film.
[0030] When the cutting mechanism 6 is working, the clamping mechanism 5 moves with the first slider 2 to a preset distance from the cutting mechanism 6, and the straight section 521 of the two crank arms 52 clamps the graphene electrothermal film between them, and the pressing mechanism 7 clamps the graphene electrothermal film between the pressure plate 72 and the base plate 71.
[0031] Specifically, in the working state, the graphene electrothermal film is transferred to the input side of the clamping mechanism 5 and passes through the pressing mechanism 7. At this time, the electrothermal film is located between the pressure plate 72 and the base plate 71, and the pressure plate 72 moves upward to leave the base plate 71 without pressing the electrothermal film. The clamping mechanism 5 is controlled to move close to the electrothermal film, with the straight section 521 opening towards the electrothermal film, and the electrothermal film is placed between the two straight sections 521. The clamping drive 54 is controlled to extend, driving the connecting rod 53 to move forward, and the crank arm 52 moves around its hinge point with the connecting frame 51 along... Figure 4 Rotate clockwise as shown until the straight section 521 of the two crank arms 52 clamps the heating film between them; control the mounting base 55 along... Figure 1 Moving in the direction of the arrow, the clamping mechanism pulls one end of the heating film forward a certain distance (depending on the size of the pre-cut heating film), controlling the pressure plate 72 to descend and press the heating film, at which point the heating film is fixed between the clamping mechanism and the pressing mechanism; the cutting mechanism 6 is activated to cut the heating film along a direction perpendicular to the production line conveying direction, after which the cutting mechanism 6 resets; the clamping drive 54 is controlled to retract, driving the connecting rod 53 to move backward, and the crank arm 52 then moves around its hinge point with the connecting frame 51 along... Figure 3 The mechanism rotates counterclockwise until the straight sections 521 of the two crank arms 52 open, releasing the cut electrothermal film. A conveyor belt 9, oriented in the same direction as the production line, is provided on the lower side of the clamping mechanism 5 to transport the cut graphene electrothermal film to the next process.
[0032] In this embodiment, multiple clamping mechanisms 5 are provided and arranged on the mounting base 55 along the direction perpendicular to the production line transmission, and are used together to stably clamp the graphene electrothermal film.
[0033] In this embodiment, the cutting mechanism 6 includes a cutter 61 (with its own rotary motor). The cutter 61 is connected to the second slider 4 via a connecting seat 64 and can move linearly along the direction of the second slide rail to perform cutting. The cutter 61 is also connected to a lifting drive 62 for driving its lifting and lowering, which is used to adjust the height of the cutter 61 so that the blade height position is adapted to the electrothermal film to be cut.
[0034] Further preferably, a support plate 63 is provided on the lower side of the blade of the cutter 61, and is fixed to the cutter 61. The surface of the support plate 63 has a clearance hole 631 that matches the blade. The advantage is that the support plate 63 is fixed to the cutter as a whole, and the overall cutting direction is horizontal and perpendicular to the production line conveying direction. Therefore, during cutting, there is no need to control the support plate separately to make way for other working parts. It also plays a supporting role on the bottom side of the electrothermal film to be cut. It only needs to move with the cutter, making the process simpler.
