Description

Technical Field

[0001] The present invention relates to the technical field of processing equipment for protective films of electronic devices, and more specifically, to a film cutting machine for improving cutting smoothness. Background Art

[0002] A film cutting machine, also known as a membrane cutting machine, is often used to cut the front and rear panel protective films of mobile phones and tablet computers. Different from traditional die cutting that requires customizing a die according to the pattern, which is time-consuming and laborious in small batch and multi-variety personalized die cutting, the film cutting machine solves the above application problems and is the best choice for small batch and multi-variety die cutting. The film cutting machine uses a motor to drive a cutting knife to trim the edges of the protective film of the electronic device and cut the mobile phone film into a standard shape and width. Figure 1 It is a schematic diagram of a prior art film cutting machine. When using the prior art film cutting machine 1 to cut the film, first manually select the type of film to be cut on the operation panel 13 of the film cutting machine 1, then manually take a film and place it on the base 11 of the film cutting machine 1. The film is pressed onto the roller shaft 16 of the film cutting machine 1 by the pressure roller 12. The roller shaft 16 is arranged on the base 11 of the film cutting machine 1, and the film cutting machine 1 is manually started. The roller shaft 16 of the film cutting machine 1 rotates to cooperate with the movement of the pressure roller 12 to move the position of the film, and at the same time, the cutting part 14 cuts the film. By driving the transverse movement of the cutting part 14 by the motor 15 and driving the longitudinal movement of the film by the roller shaft 16, a preset planar pattern is cut on the film.

[0003] For the prior art film cutting machine 1, since the cutting knife of the cutting part 14 is a traditional two-edge cutting knife, this kind of cutting knife is widely used in the die cutting field because of its high cutting efficiency when cutting the protective film of plastic material. However, when this kind of cutting knife cuts a line with a large angle change relative to the cutting edge surface, such as a line perpendicular to the cutting edge, it often gets stuck, resulting in unsmooth cutting. In severe cases, the cutting knife may even break. Summary of the Invention

The cutter control shaft 251 is movably connected to the cutter shaft sleeve 241 and can drive the cutter shaft sleeve 241 and the cutter 242 to move in a direction perpendicular to the base 21.

[0045] Please refer to Figures 5 - 6, the die cutting machine 2 further includes a vertical control mechanism 29. The vertical control mechanism 29 is composed of a series of components and is used to control the movement of components such as the cutting knife 242 in the direction perpendicular to the base 21. The vertical control mechanism 29 includes side plates 290, a first connecting rod 291, and a limit block 296. The first connecting rod 291 is provided with a first assembly hole 2911 and a second assembly hole 2912. The first assembly hole 2911 is opened at the first end of the first connecting rod 291, and the shape of the first assembly hole 2911 can be a narrow groove of a rectangle with rounded corners, in which a limit block 296 fixed on the side plate 290 is accommodated. The limit block 296 can play a role in limiting and supporting the first connecting rod 291. The side plate 290 is provided with a second limit hole 2901, and the shape of the second limit hole 2901 can be a narrow groove of a rectangle with rounded corners. The long side of the narrow groove is perpendicular to the base 21, and the width of the narrow groove is adapted to the diameter of the cutting knife control shaft 251.

The cutting knife control shaft 251 can rotate freely in the second assembly hole 2912. The cutting knife control shaft 251 can move along the narrow groove direction, that is, the direction perpendicular to the base 21, under the limitation of the second limit hole 2901. The vertical control mechanism 29 further includes a second connecting rod 292. The first end of the second connecting rod 292 is movably connected to the traction rod 295, and the second end of the second connecting rod 292 is movably connected to the side plate 290. The end of the pressure wheel shaft 22 is connected to the second connecting rod 292.

When the die cutting machine 2 is working normally, the control system issues an instruction to the trolley motor 27, and the trolley motor 27 can move the trolley 25 through the trolley belt 28 and complete the cutting through the cutting structure 24 fixed on the trolley 25. The vertical control mechanism 29 can be provided only on one side of the die cutting machine 2 or can be symmetrically provided on both sides of the die cutting machine 2. When the vertical mechanism 29 is symmetrically provided on both sides of the die cutting machine, it is more conducive to improving the stability of the system.

[0046] Please refer to Figures 7 - 10 , the cutting blade 242 includes a blade core 2421, a heat conduction ring 2422, a heating element 2425, and a heat insulation ring 2424. The cross-sections of the heat conduction ring 2422 and the heat insulation ring 2424 are circular rings. The heat conduction ring 2422 is nested inside the heat insulation ring 2424. An annular heat dissipation groove 2423 is provided between the heat conduction ring 2422 and the heat insulation ring 2424. The heat dissipation ring 2423 can facilitate the heat dissipation of the heat conduction ring 2422 and also provide a buffer space when the heat conduction ring 2422 expands due to heat, preventing the heat conduction ring 2422 from squeezing the heat insulation ring 2424 when it expands due to heat. The blade core 2421 includes a blade core main body 24211 and a cutting part 24212. The blade core main body 24211 is cylindrical, and the cutting part 24212 is conical. The vertex of the cone faces the film cutting direction. The heat insulation ring 2424 has a cylindrical upper seat body 24241 and a tubular heat insulation part 24242 located at the bottom of the upper seat body 24241. One end of the heating element 2425 is embedded in the bottom of the upper seat body 24241, and the other end of the heating element 2425 extends into the inner cavity of the tubular heat insulation part 24242. The upper end of the blade core main body 24211 is embedded in the bottom of the upper seat body 24241, and the conical cutting part 24212 at the lower end of the blade core main body 24211 extends out of the tubular heat insulation part 24242. The middle section of the blade core main body 24211 passes through the tubular heat insulation part 24242; the entire heat conduction ring 2422 is located in the inner cavity of the tubular heat insulation part 24242, and the part of the heating element 2425 located in the inner cavity of the tubular heat insulation part 24242 is embedded in the heat conduction ring 2422. The blade core 2421 is nested in the heat conduction ring 2422. When the heat conduction ring 2422 is heated, the blade core 2421 nested in the heat conduction ring 2422 can be heated. The heat insulation ring 2424 covers the side of the heat conduction ring 2422, and the end of the heat insulation ring 2424 protrudes from the end of the heat conduction ring 2422 in the direction of the vertex of the blade core 2421.

[0047] When the die-cutting machine 2 is working normally, the control system sends cutting instructions to relevant components according to the received cutting pattern instructions. After the film moves into place through the pressure wheel 221 and the roller 26, the control system sends a heating instruction to the heating element 2425. The heating element 2425 generates heat and transfers the heat to the cutter core 2421 through the heat-conducting ring 2422. The electromagnetic device 293 is powered on, causing the traction rod 295 to move downward. The traction rod 295 drives the first connecting rod 291 and the second connecting rod 292 to move downward. The first connecting rod 291 pulls the cutter control shaft 251 to move in a direction perpendicular to the base 21. The cutter shaft sleeve 241 and the cutter 242 connected to the cutter control shaft 251 move in a direction perpendicular to the base 21 at the same time. When the movement of relevant components stops due to the action of the limit block 296, the cutter 242 is exactly at the height where it can cut the film. The film melts under the high temperature of the cutter core 2421, enabling the cutter 242 to improve the film-cutting efficiency. The cutter 242 completes the film-cutting work driven by the trolley 25. When the control system needs to lift the cutter 242, the electromagnetic device 293 is powered off, and relevant components complete the reset under the action of the spring 294, lifting the cutter 242 at the same time. The heating element 2425 stops heating. During cutting, the pressure wheel shaft 22 pulled by the second connecting rod 292 moves downward, increasing the friction between the pressure wheel 221 and the roller 26 and enhancing the stability of cutting.

[0048] Compared with the prior art, in the film cutting machine 2 of the present invention, the cutter core 2421 is designed such that the cutter core body 24211 is cylindrical and the cutting part 24212 is conical. The tip of the cutting part 24212 is a cutting edge that can perform a cutting action in any film cutting direction. When the cutting part 24212 changes the cutting angle, it is not only not easily broken, but also very smooth, effectively solving the defects of the prior art film cutting machine that the cutting is not smooth and the cutting needle is easily broken. Cooperating with heating the cutter core 2421 can cut the film with a plastic texture more effectively. The heat insulation ring 2424 covers the side of the heat conduction ring 2422, and the end of the heat insulation ring 2424 protrudes in the vertex direction of the cutter core 2421 compared with the end of the heat conduction ring 2422, which can prevent the heat conduction ring 2422 from causing harm to the user and prevent the heat conduction ring 2422 from damaging the film when the cutting point of the cutter core 2421 is too deep. The vertical control mechanism 29 and the cutter control shaft 251 are provided, so that the cutter 242 can move in a direction perpendicular to the base 21 under the action of the above mechanism, ensuring that the cutter 21 can cut the film vertically and preventing uneven cutting caused by the cutter 21 not being perpendicular to the film. The trolley 25 slides along the fixedly arranged trolley slide shaft 252, which can ensure the stability of the trolley 25, thereby ensuring the stability of the cutting process. The cutter slide shaft 2411 and the cutter shaft sleeve 241 are arranged on the cutting mechanism 24, which can ensure the running track of the cutter 242. The cutter 242 can only move along the direction of the cutter slide shaft 2411, ensuring the stability of the direction of the cutter 242. The first limiting hole 253 is opened on the trolley 25, and cooperating with the cutter control shaft 251 can ensure that the moving direction of the cutter control shaft 251 is perpendicular to the base 21, so as to ensure that the moving direction of the cutter 242 driven by the cutter control shaft 251 is also perpendicular to the base 21, further determining the stability of the direction of the cutter 242. By setting the first connecting rod 291 and the limiting block 296 and opening the second limiting hole 2901 on the side plate, it can be ensured that when the first connecting rod 291 is pulled, it can drive the cutter control shaft 251 to move in a direction perpendicular to the bottom plate 21.
