Description

Technical Field

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

[0002] Automotive paint protection film is a transparent film specifically designed to cover the surface of a car to protect the paint from scratches and damage that may occur during daily use, such as from stones, insects, resin, bird droppings, ultraviolet rays, and other factors. This protective film is typically made of polyurethane and features wear resistance, weather resistance, chemical corrosion resistance, and high transparency. Cutting is a critical step in the production of this protective film. Existing machine cutting devices often require a considerable amount of time for debugging and calibration when changing cutting blades, affecting production efficiency. Therefore, a protective film edge cutting device is proposed to overcome the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a protective film edge cutting device. By rotating a turntable, a rotating rod and gear rotate, which in turn moves a rack and retracts it, releasing the T-block's restraint. This allows the stop block to be removed from the T-block, and then the cutting blade can be pulled to move the T-strip within the T-groove. This allows for quick removal and replacement of the cutting blade and T-strip, solving the problem that replacing cutting blades typically requires lengthy debugging and calibration, impacting production efficiency. This invention proposes a protective film edge cutting device to overcome the aforementioned problems.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model is a protective film edge cutting device, including a worktable, a mounting strip, and a stop block. The bottom end of the mounting strip has a T-shaped groove, and two T-shaped blocks are respectively provided on both sides of one end of the mounting strip. Each T-shaped block has an insertion hole. A T-shaped strip fits inside the T-shaped groove, and a cutting blade is provided at the bottom end of the T-shaped strip. The stop block has two through holes, and one end of each of the two T-shaped blocks is inserted into the through holes. The stop block has a circular groove inside, and sliding grooves are respectively provided at the upper and lower parts of the circular groove. One end of each sliding groove communicates with the two through holes. A gear is provided inside the circular groove, and racks fit inside each of the two sliding grooves. The gear meshes with the two racks, and one end of each circular groove is inserted into the insertion hole.

[0006] Furthermore, a stepped block is provided at the top center of the mounting strip, and two symmetrical mounting holes are provided on the stepped block. Springs are provided inside the two mounting holes, and one end of each spring is connected to a limit block.

[0007] Furthermore, a gantry frame is provided at the top of the workbench, and an electric actuator is provided on the gantry frame. The output end of the electric actuator is provided with a mounting block.

[0008] Furthermore, a stepped groove is provided at the bottom of the mounting block, and the stepped block fits into the stepped groove. Limiting holes are provided on both sides of the mounting block, and the limiting holes are connected to the stepped groove. A pressure block fits inside the limiting hole, and one end of the limiting block is inserted into the stepped groove.

[0009] Furthermore, a feed groove is provided on the worktable, which is located below the cutting blade.

[0010] This utility model has the following beneficial effects:

[0011] This invention uses a rotating turntable to drive a rotating rod and gear to rotate, thereby moving a rack and retracting it to release the T-block's restriction. This allows the stop block to be removed from the T-block, and then the cutting blade can be pulled to move the T-strip in the T-groove. This allows for quick removal and replacement of the cutting blade and T-strip, solving the problem that changing cutting blades usually requires a long time for debugging and calibration, which affects production efficiency.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Please see Figure 1-5 This utility model provides a technical solution: a protective film edge cutting device, including a worktable 1, a mounting strip 5, and a stop block 7. The mounting strip 5 is a long strip structure with a T-shaped groove 506 at its bottom end. T-shaped blocks 505 are respectively provided on both sides of one end of the mounting strip 5, and insertion holes are respectively provided on the two T-shaped blocks 505. A T-shaped strip 601 is fitted inside the T-shaped groove 506, and a cutting blade 6 is provided at the bottom end of the T-shaped strip 601. A cutting groove is provided on the worktable 1, and the cutting groove is located below the cutting blade 6. The stop block 7 is rectangular. The structure includes two through holes 702 on the stop block 7, with one end of each of the two T-shaped blocks 505 inserted into the through holes 702. The stop block 7 has a circular groove 704 inside, with sliding grooves 703 on the upper and lower parts of the circular groove 704. One end of each sliding groove 703 is connected to the two through holes 702. A gear 706 is installed inside the circular groove 704, and racks 705 are fitted inside the two sliding grooves 703. The gear 706 meshes with the two racks 705, and one end of each circular groove 704 is inserted into the insertion hole.

[0021] By rotating the turntable 701, the rotating rod and gear 706 are driven to rotate, thereby moving the rack 705 to retract and release the limit on the T-block 505. This allows the stop block 7 to be removed from the T-block 505. Then, the cutting blade 6 can be pulled to move the T-strip 601 in the T-slot 506, allowing the cutting blade 6 and the T-strip 601 to be quickly removed and replaced. This solves the problem that when changing cutting blades, it usually takes a long time to adjust and calibrate, which affects production efficiency.

[0022] The top center of the mounting strip 5 is provided with a step block 501, and two symmetrical mounting holes 502 are provided on the step block 501. Springs 503 are provided inside the two mounting holes 502 respectively, and one end of each spring 503 is connected to a limit block 504. The top of the workbench 1 is provided with a gantry frame 2, and an electric push rod 3 is provided on the gantry frame 2. The output end of the electric push rod 3 is provided with a mounting block 4, which is a rectangular structure. A step groove 403 is provided at the bottom of the mounting block 4, and the step block 501 fits in the step groove 403. Limit holes 401 are provided on both sides of the mounting block 4, and the limit holes 401 communicate with the step groove 403. A pressure block 402 fits inside the limit hole 401, and one end of the limit block 504 is inserted into the step groove 403.

[0023] When it is necessary to disassemble the cutting blade 6, first press the pressure block 402 to squeeze the limiting block 504 and the spring 503, causing the limiting block 504 and the spring 503 to retract and release the limitation on the step block 501. Then rotate the mounting strip 5 to make the step block 501 rotate in the step groove 403, which will drive the cutting blade 6 to rotate and lay it horizontally, so that the cutting blade 6 can be pulled out when disassembling the cutting blade 6.
