Description

Technical Field

[0001] This utility model belongs to the field of adhesive film slitting technology, and specifically relates to an adhesive film slitting device. Background Technology

[0002] When producing tape, glue needs to be applied to the surface of the film. After the film is dried, it needs to be wound onto a tube to form a master roll. At this time, the width of the film is too large and does not meet the usage requirements. Therefore, a slitting device is needed to cut the film and then wind it onto a cardboard tube to make the finished tape.

[0003] Chinese patent CN220467076U discloses a film slitting machine, belonging to the technical field of film processing equipment. It includes a machine base with two opposing vertical plates on the top. A tool holder is fixedly connected between the two plates. A sliding sleeve is slidably connected to the outer side of the tool holder. A cutting blade is installed at the bottom of the sliding sleeve. A spring is fixedly connected to the top of the sliding sleeve, and a pressure plate is fixedly connected to the top of the spring. Connecting plates are fixedly connected to both ends of the pressure plate, and a limiting plate is fixedly connected to the bottom of the connecting plate. A sliding opening is formed through the side wall of the sliding sleeve relative to the limiting plate. Side sliding grooves are formed on both sides of the tool holder relative to the limiting plate, and the side sliding grooves slide smoothly and adapt to the limiting plate. Limiting grooves are evenly formed near the top of the inner groove of the side sliding groove on the tool holder. This solution utilizes the pressure plate to release the limiting position of the sliding sleeve for tool installation. After the sliding sleeve slides to an appropriate position, the spring rebounds and limits the sliding sleeve again, enabling rapid adjustment of the tool spacing.

[0004] The above solution can quickly unlock the sliding sleeve by pressing the pressure plate, but when adjusting the tool spacing, it is still necessary to move the sliding sleeve one by one, which is a relatively complicated operation. In addition, when limiting the sliding sleeve, the limiting plate needs to be inserted into the limiting groove, and the position of the limiting groove is fixed, resulting in a small adjustable range of tool spacing in the above solution. Utility Model Content

[0005] The present invention aims to provide a film slitting device to solve the problem that the operation steps for adjusting the blade spacing in the above-mentioned solutions are relatively complicated.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A film slitting device includes a frame, a support assembly, and an adjustment assembly. The frame has a mounting groove at its top. The support assembly includes two guide rods fixedly spaced within the mounting groove. A first slider and several second sliders are slidably mounted on the outside of the guide rods. A cutter is mounted on the bottom of each of the first and second sliders. The adjustment assembly includes a threaded rod rotatably mounted within the mounting groove. The first slider is fitted onto the threaded rod. A connecting lug is fixedly mounted on the top of one inner wall of the mounting groove. A first connecting rod is rotatably connected to the top of the first slider and the bottom of the connecting lug. A second connecting rod is rotatably connected to the top of the second slider. Two adjacent second connecting rods are rotatably connected end-to-end. The ends of the two first connecting rods are rotatably connected to the ends of adjacent second connecting rods.

[0008] The principle and effects of this technical solution:

[0009] In the initial state, since both the first and second sliders are slidably sleeved on the two guide rods, rotation of the first and second sliders is prevented. When it is necessary to adjust the distance between the cutters, the threaded rod is rotated, and the first slider moves along the length of the guide rod and drives the first connecting rod to rotate. When the first connecting rod rotates, it drives each of the second connecting rods to rotate, and when the second connecting rods rotate, it drives the corresponding second slider to move.

[0010] With the above settings, multiple cutters can be moved simultaneously by rotating the threaded rod, while maintaining the same distance between any two adjacent cutters. This eliminates the need to move the first or second slider one by one, simplifying the operation steps when adjusting the cutter spacing. Furthermore, rotating the threaded rod increases the adjustable range of the distance between the cutters.

[0011] In this utility model, the second slider includes a first block and a second block arranged opposite to each other. A slot is provided on one side of the first block. The second block is inserted into the slot and connected to the first block by bolts. A first groove aligned with the guide rod is provided on the inner side wall of the slot. A second groove aligned with the first groove is provided on the side of the second block near the first block. The inner side walls of the first groove and the second groove form a sliding cavity adapted to the guide rod.

[0012] In this invention, a T-shaped slide rail is provided on the inner sidewall of the slot between the two first grooves, and a limiting groove that cooperates with the slide rail is provided on the sidewall of the second block.

[0013] In this utility model, connecting plates are fixedly provided at the upper and lower ends of the second block, and through holes are provided on the connecting plates. Screw holes aligned with the through holes are provided on the side wall of the first block.

[0014] The principle and effects of this technical solution:

[0015] When the width of the finished tape is small and a cutter is required, place the first and second blocks that make up the second slider on both sides of the guide rod, align the first and second grooves with the guide rod, and insert the slide rail into the limiting groove. Slide the second block relative to the first block until the through hole is aligned with the screw hole. Then pass the bolt through the through hole and insert it into the screw hole until the bolt head abuts against the connecting plate.

[0016] With the above settings, the number of second sliders sleeved on the guide rod can be easily increased or decreased according to the width of the finished tape, ensuring that the device can complete the slitting of the master roll of tape in one go and improve slitting efficiency.

[0017] In this invention, bolts are inserted into the top of both the first slider and the first block. A bushing is fitted onto the shank of each bolt. The middle portion of the second connecting rod, located above the second slider, is rotatably fitted onto the corresponding bushing, and the end portion of the first connecting rod, located above the first slider, is rotatably fitted onto the corresponding bushing. This arrangement achieves the goal of rotatably connecting the top of the first slider to the first connecting rod, and rotatably connecting the top of the second slider to the second connecting rod.

[0018] In this invention, the cutter below the second slider is mounted on the bottom of the first block.

[0019] In this invention, a drive component that is connected to the threaded rod is fixedly mounted on the outer wall of the frame. This configuration allows for easier rotation of the threaded rod by the operator, saving manpower, and prevents the threaded rod from continuing to rotate after the first slider has moved to an appropriate position, thus avoiding displacement of the first slider during the slitting process and improving the slitting quality of the adhesive film.

[0027] As attached Figure 1-4 As shown, this utility model discloses a film slitting device, including a frame 10, a support assembly, and an adjustment assembly. The top of the frame 10 is provided with a mounting groove 11. The support assembly includes two guide rods 20 fixedly disposed at intervals within the mounting groove 11. A first slider 30 and several second sliders 40 are slidably sleeved on the outside of the guide rods 20. A cutter 50 is installed at the bottom of both the first slider 30 and the second slider 40. The adjustment assembly includes a threaded rod 61 rotatably disposed within the mounting groove 11. The first slider 30 is fitted onto the threaded rod 61. A connecting ear 12 is fixedly disposed on the top of one inner sidewall of the mounting groove 11. A first connecting rod 62 is rotatably connected to the top of the first slider 30 and the bottom of the connecting ear 12, respectively. A second connecting rod 63 is rotatably connected to the top of the second slider 40. Two adjacent second connecting rods 63 are rotatably connected end to end in sequence. The ends of the two first connecting rods 62 are rotatably connected to the ends of the adjacent second connecting rods 63, respectively. The distance between the rotatable connection points at both ends of the second connecting rod 63 is twice the distance between the rotatable connection points at both ends of the first connecting rod 62.

[0028] In this embodiment, the second slider 40 includes a first block 41 and a second block 42 arranged opposite to each other. A slot 411 is provided on one side of the first block 41. The second block 42 is inserted into the slot 411 and connected to the first block 41 by bolts. A first groove 412 aligned with the guide rod 20 is provided on the inner side wall of the slot 411. A second groove 421 aligned with the first groove 412 is provided on the side of the second block 42 near the first block 41. The inner side walls of the first groove 412 and the second groove 421 form a sliding cavity adapted to the guide rod 20.

[0029] In this embodiment, a T-shaped slide rail 414 is provided on the inner sidewall of the slot 411 between the two first grooves 412, and a limiting groove 424 that cooperates with the slide rail 414 is provided on the sidewall of the second block 42.

[0030] In this embodiment, connecting plates 422 are fixedly provided at the upper and lower ends of the second block 42, and through holes 423 are provided on the connecting plates 422. The side wall of the first block 41 is provided with screw holes 413 aligned with the through holes 423.

[0031] In this embodiment, bolts 70 are inserted into the top of the first slider 30 and the first block 41. A bushing 80 is sleeved on the rod of the bolt 70. The middle part of the second connecting rod 63 located above the second slider 40 is rotatably sleeved on the corresponding bushing 80. The end of the first connecting rod 62 located above the first slider 30 is rotatably sleeved on the corresponding bushing 80.

[0032] In this embodiment, the cutter 50 below the second slider 40 is mounted on the bottom of the first block 41.

[0033] In this embodiment, a drive component 90 is fixedly provided on the outer side wall of the frame 10 and is connected to the threaded rod 61 in a transmission manner. The drive component 90 is a motor, and the output end of the motor is connected to the threaded rod 61 in a transmission manner through a coupling.

[0034] The specific implementation process is as follows:

[0035] In the initial state, since the first slider 30 and the second slider 40 are both slidably sleeved on the two guide rods 20, the first slider 30 and the second slider 40 are prevented from rotating. When it is necessary to adjust the spacing of the cutter 50, the threaded rod 61 is rotated, and the first slider 30 moves along the length direction of the guide rod 20 and drives the first connecting rod 62 to rotate. When the first connecting rod 62 rotates, it drives each second connecting rod 63 to rotate. When the second connecting rod 63 rotates, it drives the corresponding second slider 40 to move.

[0036] When the width of the finished tape is small and a cutter 50 is required, the first block 41 and the second block 42 constituting the second slider 40 are placed on both sides of the guide rod 20, and the first groove 412 and the second groove 421 are aligned with the guide rod 20 respectively. The slide rail 414 is inserted into the limiting groove 421, and the second block 42 slides relative to the first block 41 until the through hole 423 is aligned with the screw hole 413. Then, the bolt is passed through the through hole 423 and inserted into the screw hole 413 until the bolt head abuts against the connecting plate 422.

[0037] The parts of the device not covered herein are the same as or can be implemented using existing technologies.
