Description

Technical Field

[0001] This utility model relates to the field of coating technology for vibratory knife cutting machines, and specifically to a coating mechanism for vibratory knife cutting machines. Background Technology

[0002] In textile, leather, advertising material, and composite material processing, vibrating knife cutting machines have become indispensable key processing equipment due to their high-precision and high-efficiency cutting performance. Through the high-speed reciprocating motion of the vibrating knife head, it can accurately cut various flexible or semi-flexible materials, meeting the processing needs of different industries for complex shapes and intricate patterns.

[0003] However, in actual production, for materials with special surface characteristics, such as those that are easily scratched, easily attract dust, or have special functional requirements (such as antistatic or waterproof properties), a coating process is often necessary before cutting. Coating not only protects the material surface from damage during cutting but also imparts additional functional properties as needed, improving product quality and performance.

[0004] However, the laminating function of most vibratory knife cutting machines currently on the market has significant limitations. Existing laminating operations typically rely on manual labor. Workers must first lay the protective film flat on the material surface, then carefully squeeze out air bubbles between the film and the material using tools such as scrapers to ensure a smooth, wrinkle-free finish. This process is not only labor-intensive and cumbersome, but also extremely inefficient. In mass production, the speed of manual laminating is far from meeting the high-speed cutting requirements of vibratory knife cutting machines, severely restricting the efficiency of the entire production process.

[0005] Therefore, based on this, a design or technical improvement is proposed to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned shortcomings and provide a coating mechanism for a vibrating knife cutting machine.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A film coating mechanism for a vibrating knife cutting machine includes a vibrating knife cutting machine body, a frame is provided on the vibrating knife cutting machine body, a plurality of long rods are slidably arranged on the vibrating knife cutting machine body, and a positioning plate is fixedly installed at the end of the plurality of long rods. A screw is rotatably arranged on the positioning plate, and a positioning rod is rotatably arranged at one end of the screw, and a handle is fixedly arranged at the other end of the screw.

[0009] The vibrating knife cutting machine body has cavities on both sides of the top end, and two sets of rotating shafts are set in the cavities. Synchronous belts are sleeved on the two sets of rotating shafts. A second servo motor is fixedly installed on the vibrating knife cutting machine body, and a linkage rod is fixedly installed on the output shaft of the second servo motor. The linkage rod passes through the two sets of rotating shafts.

[0010] A mounting block is fixedly installed on the synchronous belt, and a film clamping mechanism is provided on the mounting block for gripping the film.

[0011] The frame is equipped with a flattening mechanism for smoothing the film;

[0012] The long rod is equipped with multiple tension adjustment mechanisms for adjusting the tension of the film.

[0013] Furthermore, the film clamping mechanism includes a movable frame fixedly mounted on the mounting block. The movable frame has sliding grooves on both sides, and a sliding block is slidably mounted in the sliding groove. A connecting block is fixedly connected to one side of the sliding block, and a first rotating block is rotatably connected to one side of the connecting block. An electric push rod is provided on the movable frame, and one end of the electric push rod is fixedly connected to the connecting block.

[0014] Furthermore, a second rotating kun is rotatably mounted on the movable frame, and a first servo motor is fixedly mounted on the movable frame, with the output shaft of the first servo motor fixedly connected to one end of the second rotating kun.

[0015] Furthermore, the flattening mechanism includes a fixed plate fixedly installed on the frame, and a cylinder fixedly connected to the frame is provided at the bottom end of the fixed plate. Two sets of limiting rods are fixedly installed on the fixed plate, and a connecting plate is fixedly connected to the ends of the two sets of limiting rods. A pressing rod is rotatably installed on the connecting plate.

[0016] Furthermore, the fixed plate and the cylinder are slidably provided with multiple sets of limiting rods, and the ends of the multiple sets of limiting rods are connected to the connecting plate.

[0017] Furthermore, the long rod has multiple sets of adjustment slots, and the multiple sets of tension adjustment mechanisms include adjustment rods hinged to the long rod, with a groove on one side of the adjustment rod, a support rod hinged in the groove, and a tension wheel rotatably mounted on the adjustment rod.

[0018] Furthermore, the vibrating knife cutting machine body has a first storage slot and a second storage slot on both sides, and a long rod is slidably installed in both the first storage slot and the second storage slot. Multiple sets of fixing bolts are rotatably installed on the outer surfaces of both ends of the vibrating knife cutting machine body.

[0019] Furthermore, a housing is fixedly installed at the end of the main body of the vibrating knife cutting machine, and a linkage rod is installed inside the housing.

[0020] Compared with existing technologies, the beneficial effects of this solution are:

[0021] 1. By precisely adjusting the screw through rotating the handle, the positioning rod firmly clamps the film roll, effectively preventing the film from slipping or shifting during subsequent operations. During film transfer, from the reasonable path setting of the film on the tension wheel, to the synchronous belt driving the installation block to achieve uniform film laying, and then to the film clamping mechanism precisely fixing the film, work efficiency is greatly improved, while ensuring high-quality completion of lamination. This allows the film to cover the surface of the cut material smoothly and without wrinkles, meeting high-standard production requirements.

[0022] 2. By driving the first servo motor, the friction between the first and second rotating rollers can automatically move the film to one end, facilitating quick film roll changes and saving significant time and manpower. During film transport, a synchronous drive cylinder drives a pressure roller to evenly press the film surface, continuously flattening the film and effectively eliminating wrinkles and bubbles, ensuring a tight bond between the film and the cutting material, thus improving coating quality.

[0032] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] like Figure 1-7 The illustrated coating mechanism for a vibratory knife cutting machine includes a vibratory knife cutting machine body 1, a frame 2 mounted on the vibratory knife cutting machine body 1, multiple sets of long rods 4 slidably mounted on the vibratory knife cutting machine body 1, and positioning plates 6 fixedly mounted at the ends of the multiple sets of long rods 4. A screw 611 is rotatably mounted on the positioning plate 6, and a positioning rod 612 is rotatably mounted at one end of the screw 611. A handle 613 is fixedly mounted at the other end of the screw 611. Cavities 211 are opened on both sides of the top of the vibratory knife cutting machine body 1, and two sets of rotating shafts 212 are arranged in the cavities 211. Two sets of rotating shafts 212 are fitted with synchronous belts 213. A second servo motor 812 is fixedly installed on the main body 1 of the vibrating knife cutting machine, and a linkage rod 813 is fixedly installed on the output shaft of the second servo motor 812. The linkage rod 813 passes through the two sets of rotating shafts 212. A mounting block 711 is fixedly installed on the synchronous belt 213, and a film clamping mechanism is installed on the mounting block 711. The film clamping mechanism is used to grip the film. A flattening mechanism is installed on the frame 2 for smoothing the film. Multiple tension adjustment mechanisms are installed on the long rod 4 for adjusting the tension of the film.

[0034] In one embodiment, the film clamping mechanism includes a movable frame 7 fixedly mounted on a mounting block 711. Slide grooves 714 are provided on both sides of the movable frame 7, and a sliding block 715 is slidably mounted within each slide groove 714. A connecting block 716 is fixedly connected to one side of the sliding block 715, and a first rotating kun 8 is rotatably connected to one side of the connecting block 716. An electric push rod 713 is provided on the movable frame 7, and one end of the electric push rod 713 is fixedly connected to the connecting block 716. By using the electric push rod 713 to push the connecting block 716, the sliding block 715 connected to the connecting block 716 slides within the slide groove 714, allowing the first rotating kun 8 to move up and down, thereby achieving the clamping action of the film.

[0035] In one embodiment, a second rotating kun 9 is rotatably mounted on the movable frame 7, and a first servo motor 712 is fixedly mounted on the movable frame 7. The output shaft of the first servo motor 712 is fixedly connected to one end of the second rotating kun 9. When the film needs to be replaced, the rotation of the second rotating kun 9 can automatically remove the old film, which is convenient for the new film to be covered, reducing the complexity and time cost of manual operation.

[0036] In one embodiment, the flattening mechanism includes a fixed plate 3 fixedly mounted on the frame 2, and a cylinder 311 fixedly connected to the frame 2 is provided at the bottom end of the fixed plate 3. Two sets of limiting rods 313 are fixedly provided on the fixed plate 3, and a connecting plate 312 is fixedly connected to the ends of the two sets of limiting rods 313. A pressure jack 314 is rotatably provided on the connecting plate 312. The cylinder 311 can flexibly adjust the output pressure according to the material of the film and the film coating requirements to ensure that the pressure jack 314 applies appropriate pressure to the film to achieve a good flattening effect.

[0037] In one embodiment, the fixed plate 3 and the cylinder 311 are slidably provided with multiple sets of limiting rods 313, and the ends of the multiple sets of limiting rods 313 are connected to the connecting plate 312. The setting of the limiting rods 313 ensures the stability of the connecting plate 312 and the pressing plate 314 during the up and down movement, avoids shaking or tilting, and makes the flattening operation more uniform and reliable.

[0038] In one embodiment, the long rod 4 has multiple sets of adjustment grooves 411. The multiple sets of tension adjustment mechanisms include adjustment rods 511 hinged to the long rod 4, and a groove 512 is provided on one side of the adjustment rod 511. A support rod 513 is hinged in the groove 512. A tension wheel 5 is rotatably mounted on the adjustment rod 511. By adjusting the position of the support rod 513 in the adjustment groove 411, the angle of the adjustment rod 511 is changed, thereby adjusting the height of the tension wheel 5 and realizing the adjustment of the film tension.

[0039] In one embodiment, the vibrating knife cutting machine body 1 has a first storage groove 111 and a second storage groove 112 on both sides, and a long rod 4 is slidably installed in both the first storage groove 111 and the second storage groove 112. Multiple sets of fixing bolts 615 are rotatably provided on the outer surfaces of both ends of the vibrating knife cutting machine body 1. After the work is completed, the long rod 4 can be retracted into the first storage groove 111 and the second storage groove 112 and fixed by fixing bolts 615, thereby reducing the footprint of the equipment.

[0040] In one embodiment, a housing 811 is fixedly provided at the end of the main body 1 of the vibrating knife cutting machine, and a linkage rod 813 is provided inside the housing 811. The housing 811 can prevent the operator from accidentally contacting the linkage rod 813 during the operation of the equipment, avoid safety accidents, and protect the personal safety of the operator.

[0041] The specific workflow of this plan is as follows:

[0042] First, the film roll is stably mounted on the positioning rod 612. By rotating the handle 613, the screw 611 is precisely adjusted to ensure that the positioning rod 612 firmly clamps the film roll, preventing the film from slipping or shifting during subsequent operations. Then, the support rod 513 is adjusted so that it is accurately embedded in the corresponding adjustment groove 411 on the long rod 4. The adjustment rod 511 is erected to a suitable height to ensure that the tension wheel 5 is in the correct position, providing stable and uniform tension for the film and preventing the film from being too loose or too tight, which would affect the coating effect. Then, the film on the film roll is sequentially inserted and mounted on each tension wheel 5 to ensure that the film is flat, wrinkle-free, and has a reasonable path on the tension wheel 5, ensuring that the film is evenly stressed during transmission. Then, the second servo motor 812 is driven to rotate forward, and the linkage rod 813 rotates accordingly, driving the rotating shaft 212 to rotate, which in turn causes the synchronous belt 213 to run. The mounting block 711 moves to one end of the vibrating knife cutting machine body 1 under the drive of the synchronous belt 213. One end of the film is placed smoothly between the first rotating kun 8 and the second rotating kun 9. Then, the electric push rod 713 is driven to lower the first rotating kun 8 and clamp the film tightly with the second rotating kun 9 to ensure that the film is firmly fixed. Then, the second servo motor 812 is driven to reverse, and the film clamping mechanism returns to the other end of the vibrating knife cutting machine body 1 under the drive of the synchronous belt 213. During this process, the film is evenly and flatly laid on the surface of the cutting material to complete the film coating operation. When it is necessary to replace the film, the first servo motor 712 is driven to drive the second rotating kun 9 to rotate. Using the friction between the first rotating kun 8 and the second rotating kun 9, the film is automatically moved to one end for easy and quick replacement of the film roll.

[0043] During film transport, the synchronous drive cylinder 311 drives the connecting plate 312 to descend smoothly via the limit rod 313, so that the pressure plate 314 at the bottom of the connecting plate 312 presses evenly onto the film surface. During film movement, the pressure plate 314 continuously flattens the film, eliminating wrinkles and bubbles on the film surface, ensuring a tight fit between the film and the cutting material, and improving the coating quality. After the work is completed, the fixing bolt 615 is rotated to release the fixed state of the long rod 4, and the long rod 4 is pushed to retract smoothly into the first storage slot 111 and the second storage slot 112, reducing the equipment footprint and facilitating equipment storage and subsequent operation.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
