Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically a cutting device for automotive film production. Background Technology

[0002] Car window tinting involves applying a film to the exterior of a car to reduce the number of scratches. The film itself is a thin film, and during the production process, the film body needs to be cut on both sides using a cutting device to remove any uneven or rough edges. Then, it is wound onto a take-up roller for packaging.

[0003] A Chinese patent (publication number: CN216464845U) provides a cutting device for automotive film production, including a processing table and an assembly frame. The bottom end of the assembly frame is fixedly mounted on the upper surface of the processing table. An electric telescopic rod is mounted on the top end of the assembly frame via a fixed frame. A support frame is mounted on the output end of the electric telescopic rod. An mounting frame is fixedly mounted on the bottom end of the support frame. Lead screws are rotatably connected to both sides of the mounting frame via bearings. Hand cranks are fixedly mounted on both ends of the lead screws.

[0004] The above-mentioned equipment cuts the film using a cutting roller. However, as the cutting roller wears down over a long period of use, its cutting end is prone to curling, which affects the cutting effect and efficiency. Burrs may also be generated during the cutting process. Therefore, the cutting roller needs to be polished. However, the cutting blade of this device is located inside the worktable, which makes it quite troublesome to extend into the worktable for polishing. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device for automotive film production to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a cutting device for automotive film production, including a worktable and a cutting blade disposed within the worktable, comprising,

[0007] Two mounting frames are slidably set inside the worktable and are symmetrical about the vertical axis of the worktable. The cutting blade is rotatably connected inside the mounting frames.

[0008] The grinding part is vertically slidably set inside the mounting frame and located above the cutting blade. The vertical cross-section of the grinding part is arrow-shaped.

[0009] Two wedge-shaped blocks are set inside the worktable. As the mounting frame slides horizontally, the grinding component and the wedge-shaped blocks abut against each other, driving the grinding component to slide closer to or away from the cutting blade.

[0010] A connecting plate is attached to the mounting frame. A compression spring is attached to the connecting plate, and the other end of the compression spring is attached to the grinding part.

[0011] The workbench is equipped with a drive assembly for driving the mounting frame to slide horizontally.

[0012] Furthermore, the drive assembly includes a bidirectional lead screw rotatably connected within the worktable, a nut threaded onto the bidirectional lead screw, and the bottom of the nut being connected to the mounting frame.

[0013] Furthermore, a guide rod is connected inside the workbench, and the nut is slidably connected to the guide rod, with a sliding opening on the nut that matches the guide rod.

[0014] Furthermore, a dual-axis motor is connected inside the workbench, and the drive end of the dual-axis motor is connected to a telescopic drive shaft, the other end of which is connected to the cutting blade.

[0015] Furthermore, a connection port is provided on one side of the mounting frame, and the connection port is adapted to the wedge block.

[0016] Furthermore, it also includes a chip removal assembly, comprising a fan connected to one side of the workbench, the exhaust end of the fan being connected to a connecting pipe, the other end of the connecting pipe extending into the mounting frame, the output end of the fan being connected to a storage box, and an exhaust pipe being connected to the storage box.

[0017] Furthermore, an electric telescopic rod is connected to the worktable, which is used to drive the cutting blade to adjust its height.

[0018] Furthermore, one end of the bidirectional lead screw extends to the outside of the worktable and is connected to a knob, which has an integrally formed anti-slip texture.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. When the cutting blade needs sharpening, the drive assembly moves the mounting frame. Through the cooperation of the wedge block and the grinding element, it automatically approaches the cutting blade without manual intervention. The compression spring not only provides smooth cushioning to ensure the stability of the sharpening process, but also ensures that the grinding element maintains appropriate pressure and close contact with the cutting blade. The arrow-shaped cross-section of the grinding element can efficiently sharpen the blade from all directions, restoring its sharpness, improving cutting quality and efficiency, and reducing poor cutting of automotive film caused by blade dulling.

[0021] 2. The fan can be started during the grinding process, and the generated debris can be sucked into the storage box through the connecting pipe for easy collection. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a cutting device for automotive film production, comprising a worktable 1 and a cutting blade 2 disposed within the worktable 1, including,

[0031] Two mounting frames 301 are slidably set inside the worktable 1 and are symmetrical about the vertical axis of the worktable 1. The cutting blade 2 is rotatably connected inside the mounting frame 301.

[0032] The grinding part 302 is vertically slidably disposed within the mounting frame 301 and located above the cutting blade 2. The vertical cross-section of the grinding part 302 is arrow-shaped.

[0033] Two wedge blocks 303 are set inside the worktable 1. As the mounting frame 301 slides horizontally, the grinding part 302 and the wedge blocks 303 abut against each other, driving the grinding part 302 to slide closer to or further away from the cutting blade 2.

[0034] A connecting plate 305 is connected inside the mounting frame 301. A compression spring 304 is connected to the connecting plate 305, and the other end of the compression spring 304 is connected to the grinding part 302.

[0035] The workbench 1 is equipped with a drive assembly for driving the mounting frame 301 to slide horizontally.

[0036] In practice, when the cutting blade 2 needs to be sharpened after prolonged use, the drive assembly moves the two mounting frames 301 relative to each other. During the horizontal sliding of the mounting frames 301, when the grinding part 302 moves with the mounting frames 301 to a position corresponding to the wedge block 303, the grinding part 302 begins to abut against the wedge block 303. Due to the special shape and position of the wedge block 303 fixed within the worktable 1, as the mounting frames 301 continue to move horizontally, the grinding part 302 begins to slide vertically along the mounting frames 301 under the action of the inclined surface of the wedge block 303. Under the abutment of the wedge block 303, the grinding part 302 gradually approaches the cutting blade 2, at which point the compression spring 304 connected to the connecting plate 305 begins to be stretched. The other end of the compression spring 304 is connected to the grinding element 302. As the grinding element 302 approaches the cutting blade 2, the compression spring 304 provides a certain amount of buffering and tension, allowing the grinding element 302 to smoothly and gradually approach the cutting blade 2. When the grinding element 302 contacts the cutting blade 2, its arrow-shaped vertical cross-section allows it to effectively grind the cutting edge of the cutting blade 2.

[0037] When the mounting frame 301 completes one cutting operation and begins to move horizontally in the opposite direction, the grinding part 302, under the elastic restoring force of the compression spring 304, gradually moves away from the cutting blade 2 as the mounting frame 301 moves. Simultaneously, due to the inclined plane direction of the wedge block 303 and the reverse movement of the mounting frame 301, the grinding part 302 slides upward along the mounting frame 301 under the action of the wedge block 303, gradually returning to its initial position. During this process, the compression spring 304 continuously contracts, pulling the grinding part 302 back to a position above the cutting blade 2, away from it.

[0038] See Figure 5 The drive assembly includes a bidirectional lead screw 601 rotatably connected within the worktable 1, a nut 602 threaded onto the bidirectional lead screw 601, and the bottom of the nut 602 being connected to the mounting frame 301.

[0039] Specifically, rotating the bidirectional lead screw 601 can drive the two nuts 602 to move relative to each other or in opposite directions, thereby driving the mounting frame 301 to move synchronously.

[0040] See Figure 5 The workbench 1 is connected to a guide rod 7, and a nut 602 is slidably connected to the guide rod 7. The nut 602 has a sliding opening that matches the guide rod 7.

[0041] Specifically, the guide rod 7 can limit and guide the sliding of the nut 602, further improving the stability of the nut 602 during the sliding process.

[0042] See Figure 5 The workbench 1 is connected to a dual-axis motor 4. The drive end of the dual-axis motor 4 is connected to a telescopic drive shaft 5. The other end of the telescopic drive shaft 5 is connected to the cutting blade 2.

[0043] Preferably, the telescopic drive shaft 5 is rotatably connected within the mounting frame 301.

[0044] Specifically, the dual-axis motor 4 can drive the cutting blade 2 to rotate, which facilitates the cutting of the film, while the telescopic drive shaft 5 avoids interfering with the movement of the mounting frame 301.

[0045] See Figure 5 A connection port is provided on one side of the mounting frame 301, and the connection port is compatible with the wedge block 303.

[0046] Specifically, the connection port is designed to allow the wedge block 303 to extend into the mounting frame 301.

[0047] During the sanding process, a lot of debris is often generated. If it is not removed, the debris will fall off and become inconvenient to clean. Please refer to [the relevant documentation / reference]. Figures 2 to 6 It also includes a chip removal assembly, including a fan 901 connected to one side of the workbench 1, the exhaust end of the fan 901 is connected to a connecting pipe 903, the other end of the connecting pipe 903 extends into the mounting frame 301, the output end of the fan 901 is connected to a storage box 902, and an exhaust pipe is connected to the storage box 902.

[0048] Preferably, the storage box 902 is equipped with a filter screen to filter debris and allow the filtered air to be discharged.

[0049] In practice, the fan 901 can be started during the grinding process, and the generated debris can be sucked into the storage box 902 through the connecting pipe 903 for easy collection of debris.

[0050] refer to Figure 1 An electric telescopic rod 8 is connected to the workbench 1. The electric telescopic rod 8 is used to drive the cutting blade 2 to adjust its height.

[0051] In practice, the electric telescopic rod 8 is installed to facilitate the adjustment of the cutting height of the cutting blade 2.

[0052] refer to Figure 1 One end of the bidirectional lead screw 601 extends to the outside of the worktable 1 and is connected to a knob, which has an integrally formed anti-slip texture.

[0053] In practice, the knob is designed to facilitate the rotation of the bidirectional lead screw 601, and the anti-slip texture facilitates the application of force to rotate the knob.

[0054] Working principle: When polishing is required:

[0055] When the cutting blade 2 needs to be sharpened after prolonged use, the drive assembly moves the two mounting frames 301 relative to each other. During the horizontal sliding of the mounting frames 301, when the grinding part 302 moves with the mounting frames 301 to a position corresponding to the wedge block 303, the grinding part 302 begins to abut against the wedge block 303. Due to the special shape and position of the wedge block 303 fixed within the worktable 1, as the mounting frames 301 continue to move horizontally, the grinding part 302 begins to slide vertically along the mounting frames 301 under the action of the inclined surface of the wedge block 303. Under the abutment of the wedge block 303, the grinding part 302 gradually approaches the cutting blade 2, at which point the compression spring 304 connected to the connecting plate 305 begins to be stretched. The other end of the compression spring 304 is connected to the grinding element 302. As the grinding element 302 approaches the cutting blade 2, the compression spring 304 provides a certain amount of buffering and tension, allowing the grinding element 302 to smoothly and gradually approach the cutting blade 2. When the grinding element 302 contacts the cutting blade 2, its arrow-shaped vertical cross-section allows it to effectively grind the cutting edge of the cutting blade 2.

[0056] The fan 901 can be started during the grinding process, and the generated debris can be sucked into the storage box 902 through the connecting pipe 903 for easy collection.
