Description

Technical Field

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

[0002] In early film cutting operations, manual cutting with tools such as scissors was the most common method. Operators would cut the film to the required length using scissors or other tools. This method was extremely inefficient, especially in industrial production of large quantities of film products or in scenarios requiring high-precision film cutting.

[0003] Chinese Patent Announcement No. 201822266001.7 discloses a film unwinding machine with a cutting device, including parallel support frames. An unwinding roller is installed on the lower part of one side of the support frame, and both ends of the unwinding roller are rotatably connected to the support frame. Support roller A and support roller B are arranged horizontally and parallel to each other on the upper part of the other side of the support frame. Both ends of support roller A and support roller B are rotatably connected to the two support frames respectively. A cutting device is fixedly connected to the support frame above support roller A and support roller B. The cutting device is located between support roller A and support roller B. The cutting device includes a cutting blade and a driving device for driving the cutting blade to reciprocate between support roller A and support roller B.

[0004] However, the aforementioned patent cannot perform continuous cutting operations after improvement, which affects production efficiency. Therefore, a film cutting device is proposed to address the above problem. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example

[0022] Please see Figure 1-3 A thin film cutting device includes a base 1. A synchronous belt structure 6 is disposed inside the base 1. The synchronous belt structure 6 consists of a first servo motor, a first synchronous belt, two first synchronous pulleys, and two rollers. Two sprockets 7 are rotatably connected inside the base 1. The two sprockets 7 are respectively fixedly installed on the outer sides of the two rollers. A chain 8 is engaged on the outer sides of the two sprockets 7. The chain 8 includes several chain pins. Several T-shaped fixing plates 9 are slidably connected inside the base 1. The T-shaped fixing plates 9 are all fixedly connected to the chain pins. Two auxiliary rods 22 are fixedly installed at the bottom of each T-shaped fixing plate 9, and the auxiliary rods 22 are slidably connected to the base 1. Each T-shaped fixing plate 9 is provided with a connecting structure. An mounting plate 4, a top plate 5, and two roller structures 2 are disposed between the top and bottom of the inner wall of the base 1. A cutting structure is provided on the top plate 5.

[0023] The mounting block 10 connected to the outside of the T-shaped fixing plate 9 is installed according to the required film cutting length. The rack moves laterally and meshes with the gear through the fourth electric telescopic rod. The distance between the two inserts 12 on the outside of the bidirectional screw 11 is adjusted. When the T-shaped fixing plate 9 is connected to the mounting block 10, the two inserts 12 are inserted into the interior of the mounting block 10 to fix the T-shaped fixing plate 9 and the mounting block 10. The second electric telescopic rod 14 moves the other clamping plate 13 longitudinally. The distance between the two clamping plates 13 is adjusted to clamp the film and improve the quality of film cutting. The second servo motor on the two roller structures 2 drives several conveying rollers to be in the same direction as the film clamping and conveying, so as to convey the cut film. This device can achieve continuous and stable conveying and, together with the cutting structure, achieve continuous and uninterrupted film cutting operation.

[0024] Meanwhile, by using the auxiliary rods 22, when the T-shaped fixing plate 9 rotates to the side closer to the mounting plate 4, the two auxiliary rods 22 cooperate with the sliding grooves on the base 1 to make the T-shaped fixing plate 9 move in the same direction as the film conveying direction, thereby reducing the influence of the rotation of the chain tip on the position of the T-shaped fixing plate 9 when the sprocket 7 and chain 8 are driven.

[0025] Please see Figure 4 The cutting structure includes a movable block 18, which is inserted into and slidably connected to the top plate 5. A threaded rod 19, a worm gear, and a worm are rotatably connected inside the top plate 5, with the worm gear and worm meshing. The threaded rod 19 is fixedly connected to the worm gear and passes through the movable block 18, which is threadedly connected to it. A cutter 20 is provided at the bottom of the threaded rod 19. A handle is fixedly installed on one side of the worm, passing through one side of the top plate 5 and rotatably connected to it. Two third electric telescopic rods 21 are provided on the opposite sides of the mounting plate 4 and the top plate 5. The output ends of several third electric telescopic rods 21 are fixedly connected to the mounting plate 4 and the top plate 5, respectively. Several third electric telescopic rods 21 are inserted into and fixedly connected to the base 1.

[0026] The cutter 20 is fixedly connected to the moving block 18 by the fixed bolts, which facilitates the disassembly and replacement of the cutter 20. The position of the cutter 20 can be adjusted by manually turning the handle to move the moving block 18 on the outside of the threaded rod 19 laterally, thereby adjusting the position of the film cutting. This prevents the fixed position of the T-shaped fixing plate 9 and the chain tip from affecting the flexible adjustment of the film cutting length.

[0027] A cutting plate 15 is slidably connected to the top of the mounting plate 4. Several insert rods 16 are fixedly installed on one side of the mounting plate 4. The insert rods 16 are inserted into the interior of the cutting plate 15 and slidably connected to it. A U-shaped slider 17 is slidably connected to one side of the mounting plate 4. The U-shaped slider 17 is slidably connected to the cutting plate 15. Several compression springs are provided on the sides of the mounting plate 4 and the U-shaped slider 17 that are close to each other. The two ends of the compression springs are fixedly connected to the mounting plate 4 and the U-shaped slider 17 respectively.

[0028] Two first electric telescopic rods 3 are provided on the side of the two roller structures 2 that are far apart from each other. The output end of the first electric telescopic rod 3 is fixedly connected to the roller structure 2. Several first electric telescopic rods 3 are inserted into the base 1 and fixedly connected to it. One of the roller structures 2 has a conveying structure inside, and the conveying structure consists of a second servo motor, a second synchronous belt, two second synchronous pulleys and a conveying roller.

[0029] Several sensors are embedded in the top of the inner wall of the base 1. A controller 23 is embedded in one side of the base 1. The controller 23 is electrically connected to the first electric telescopic rod 3, the second electric telescopic rod 14, the third electric telescopic rod 21, the fourth electric telescopic rod, the first servo motor, the second servo motor and the sensors. Rubber pads are embedded in the sides of the two clamping plates 13 that are close to each other.

[0030] The insertion rod 16 is inserted into the cutting plate 15 to initially fix its position, and the U-shaped slider 17 is slidably connected to the cutting plate 15 by the action of the compression spring, thereby fixing the position of the cutting plate 15 on the top of the mounting plate 4, which facilitates the replacement of the cutting plate 15. At the same time, heat dissipation holes are provided on the device to cooperate with the motor.

[0031] Please see Figure 5 The connecting structure includes a mounting block 10, a T-shaped fixing plate 9 inserted into and slidably connected to the mounting block 10, a double-acting screw 11 rotatably connected inside the T-shaped fixing plate 9, and two insert blocks 12 threadedly connected to the outer side of the double-acting screw 11. Both insert blocks 12 pass through one side of the T-shaped fixing plate 9 and are slidably connected to it. Both insert blocks 12 are inserted into and slidably connected to the mounting block 10. Two clamping plates 13 are provided on the side of the mounting block 10 away from the T-shaped fixing plate 9, one of which is fixedly connected to the mounting block 10, and the other... The top of plate 13 is inlaid with a second electric telescopic rod 14. The output end of the second electric telescopic rod 14 is fixedly connected to another clamping plate 13. The other clamping plate 13 is slidably connected to the mounting block 10. The T-shaped fixing plate 9 is provided with a gear, a rack and a fourth electric telescopic rod. The T-shaped fixing plate 9 and the gear are rotatably connected. The bidirectional lead screw 11 passes through the gear and is fixedly connected to it. The T-shaped fixing plate 9 is slidably connected to the rack and the rack meshes with the gear. The T-shaped fixing plate 9 is fixedly connected to the fourth electric telescopic rod and the output end of the fourth electric telescopic rod is fixedly connected to the rack.

[0032] Working principle: The device operates in coordination with the equipment via the controller 23, and the position of the mounting block 10 is monitored by several sensors embedded in the top of the inner wall of the base 1 to determine the cutting position of the film. The mounting blocks 10 are connected according to the cut length of the film. A fourth electric telescopic rod drives the rack to move laterally and engage with the gear, causing the two insert blocks 12 to move repulsively into the interior of the mounting block 10, fixing the T-shaped fixing plate 9 to the mounting block 10. A second electric telescopic rod 14 on the mounting block 10 moves the other clamping plate 13 longitudinally, adjusting the distance between the two clamping plates 13 to hold the film. Several mounting blocks 10 are cyclically clamped by the synchronous belt structure 6. The film is clamped by the first, second and third sets of mounting blocks 10, which causes the clamped film to move laterally and the first set of mounting blocks 10 to pass through the top plate 5. Several third electric telescopic rods 21 are set to move the cutting plate 15 and the cutter 20 closer to each other to cut the film. At the same time, the highest position of the longitudinal movement of the cutting plate 15 is aligned with the horizontal position of the clamping plate 13 fixed on one side of the mounting block 10. The cut film is clamped and transported by the first set of mounting blocks 10, and one end of the film is clamped by the second set of mounting blocks 10. Then, with the cooperation of the third set of mounting blocks 10, the subsequent film is cut and transported.

[0033] By utilizing the roller structure 2 and the two clamping plates 13 on the mounting block 10 to move away from each other, the cut film is further conveyed. The distance between the two roller structures 2 is adjusted by the operation of the first electric telescopic rod 3 to reduce its impact on the rotation of the mounting block 10. The two third electric telescopic rods 21 on the top of the top plate 5 increase the pressure or energy required for cutting when processing thicker films, and reduce the corresponding parameters when processing thinner films to avoid damaging the film.

[0034] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
