Description

Technical Field

[0001] This utility model relates to the field of film processing, and in particular to a precision slitting machine for film processing. Background Technology

[0002] The existing precision slitting machine for film processing is a highly specialized industrial equipment designed to precisely cut a wide film longitudinally into multiple narrow rolls. The wide film is smoothly transported through a guide roller system, pressed against the anvil roller, and the upper blade presses against the anvil roller to complete the cutting and slitting of the wide film.

[0003] To facilitate the replacement of blades on the blade holder, most slitting machines often use a cantilever beam design (one side is rigidly fixed, and the blades are mounted on the cantilever arm). However, the blade holder is prone to vibration when running at high speed or cutting hard films, which causes blade jump and cutting line fluctuation. This can easily result in burrs, wavy edges, or even dimensional deviations on the slitting film edges. When performing high-precision cutting, speed must be sacrificed to reduce vibration, resulting in slower film slitting efficiency. Utility Model Content

[0004] In view of the problems in the above or existing technologies, such as the blade holder easily vibrating when running at high speed or cutting hard films, causing blade jump and cutting line fluctuation, which can easily lead to burrs, wavy edges, or even dimensional deviations on the slit film edges, and the need to sacrifice speed to reduce vibration when cutting with high precision, resulting in slow film slitting efficiency, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A supporting component includes a film slitting machine body, wherein an anvil roller is disposed inside the film slitting machine body, a slitting knife is disposed inside the film slitting machine body, a driving assembly is disposed inside the driving assembly, and a supporting component is disposed inside the driving assembly; a reinforcing component includes a tension spring, wherein the tension spring is fixedly connected inside the film slitting machine body, and a reinforcing insert is fixedly connected to the end of the tension spring away from the film slitting machine body.

[0006] In a preferred embodiment of the precision slitting machine for film processing of this utility model, the driving component includes a cylinder, which is fixedly connected inside the body of the film slitting machine. A support block is fixedly connected to the top output end of the cylinder. There are two support blocks, and two racks are fixedly connected to the inner sides of each of the two support blocks. Two gears are rotatably connected inside the body of the film slitting machine.

[0007] In a preferred embodiment of the precision slitting machine for film processing of this utility model, the two gears mesh with the two racks respectively, the two support blocks are slidably connected up and down inside the body of the film slitting machine, and the rotating shaft of the slitting knife is located inside the two support blocks.

[0008] As a preferred embodiment of the precision slitting machine for film processing of this utility model, the support assembly includes four rubber strips, which are respectively fixedly connected inside two support blocks. An installation block is inserted into the inside of each support block, and a roller is rotatably connected inside the installation block.

[0009] As a preferred embodiment of the precision slitting machine for film processing of this utility model, wherein: the roller is movably connected to the rotating shaft of the slitting knife, and the rubber strip is disposed between the support block and the mounting block.

[0010] As a preferred embodiment of the precision slitting machine for film processing of this utility model, wherein: the reinforcing insert is internally connected with ball bearings, and two vertical plates are fixedly connected to the inner sides of the two support blocks, and the length of the two upper vertical plates is greater than the length of the two lower vertical plates, and a reset component is provided inside the body of the film slitting machine.

[0011] In a preferred embodiment of the precision slitting machine for film processing of this utility model, the reset assembly includes a winding roller, which is rotatably connected inside the body of the film slitting machine. Two pull ropes are fixedly connected to the outside of the winding roller, and four steering rollers are rotatably connected inside the body of the film slitting machine.

[0012] As a preferred embodiment of the precision slitting machine for film processing of this utility model, wherein: the pull rope is movably connected to the outside of the steering roller, the end of the pull rope away from the winding roller is fixedly connected to the reinforcing block, the reinforcing block is inserted into the inside of the two vertical plates, and the ball bearing is movably connected to the outside of the upper vertical plate.

[0013] The beneficial effects of this precision slitting machine for film processing are as follows:

[0014] 1. By using the support components, two support blocks support the end of the slitting blade away from the drive source. The rollers roll between the slitting blade and the raceway of the mounting block, bearing the load and achieving low-friction rotation, and evenly distributing the pressure. This achieves the effect of supporting the end of the slitting blade away from the drive source, making the slitting blade rotate more smoothly. When performing high-precision cutting of the film, there is no need to sacrifice speed, resulting in faster film slitting efficiency.

[0015] 2. By using reinforcement components and tension springs to drive the reinforcement blocks to be inserted into the two vertical plates, the two supporting blocks that abut against each other are further fixed, the deflection force that may be generated when the slitting blade rotates is distributed, and the gears are protected. This achieves the effect of strengthening the support force of the slitting blade while extending the service life of the device. Attached Figure Description

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Example 1, referring to Figures 1-5This is the first embodiment of the present invention. This embodiment provides a precision slitting machine for film processing, which can support the cantilevered blade holder, thereby making the blade holder rotate more smoothly and without vibration, thus achieving a high cutting accuracy. It includes a support component, a film slitting machine body 10, an anvil roller 11 disposed inside the film slitting machine body 10, a slitting blade 12 disposed inside the film slitting machine body 10, a drive assembly 13 disposed inside the film slitting machine body 10, and a support assembly 14 disposed inside the drive assembly 13.

[0026] Specifically, the drive component 13 and the support component 14 work together to make the slitting blade 12 rotate more smoothly, without sacrificing speed during high-precision cutting, thus making the film slitting efficiency faster.

[0027] Furthermore, the drive assembly 13 includes a cylinder 131, which is fixedly connected inside the film slitting machine body 10. A support block 132 is fixedly connected to the top output end of the cylinder 131. There are two support blocks 132, and two racks 133 are fixedly connected to the inner side of each of the two support blocks 132. Two gears 134 are rotatably connected inside the film slitting machine body 10. Each gear 134 meshes with one rack 133. The two support blocks 132 are slidably connected up and down inside the film slitting machine body 10, and the rotating shaft of the slitting blade 12 is located inside the two support blocks 132.

[0028] During cutting, two support blocks 132 support the rotating shaft of the slitting blade 12. When changing the blade, the two support blocks 132 are located away from the rotating shaft for easy replacement, making it more convenient and faster to use.

[0029] Preferably, the support assembly 14 includes four rubber strips 141, which are fixedly connected to the interiors of two support blocks 132. An installation block 142 is inserted into the interior of the support block 132, and a roller 143 is rotatably connected to the interior of the installation block 142. The roller 143 is movably connected to the rotating shaft of the slitting blade 12, and the rubber strips 141 are disposed between the support block 132 and the installation block 142.

[0030] It should be noted that the roller 143 rolls between the shaft of the slitting blade 12 and the raceway of the mounting block 142, bearing the load and achieving low-friction rotation, thus evenly distributing the pressure and making the slitting blade 12 rotate more smoothly and stably.

[0031] In operation, the starting cylinder 131 drives the support block 132 to rise. The two cylinders 131 are symmetrical about the center point of the slitting blade 12's rotating shaft. Two racks 133 are fixed to the inner side of each support block 132. When the lower support block 132 rises, the racks 133 rise and mesh with the gear 134, causing the gear 134 to rotate and drive the racks 133 connected to the upper support block 132 to descend, thus causing the upper support block 132 to descend. This allows the two support blocks 132 to move synchronously in opposite directions, supporting the end of the slitting blade 12's rotating shaft away from the drive source. This avoids the problem of existing slitting blades 12 being rigidly fixed at one end while the other end is suspended, which easily vibrates during high-speed operation or cutting hard films, causing blade jumps and cutting line fluctuations. This can easily result in burrs, wavy edges, and even dimensional deviations on the slitting film edges. For high-precision cutting, speed must be sacrificed to reduce vibration, resulting in slower film slitting efficiency. The mounting block 142 is fixed inside the support block 132 by a rubber strip 141. Inside the mounting block 142, there are movable rollers 143. When the two support blocks 132 support the slitting blade 12, the rollers 143 roll between the rotating shaft of the slitting blade 12 and the raceway of the mounting block 142, bearing the load and achieving low-friction rotation, evenly distributing the pressure, making the rotation of the slitting blade 12 smoother and more stable, thus providing better support for the slitting blade 12. When the mounting block 142 is damaged, it can be pulled out for maintenance and replacement of a single component, making it more convenient. When the circular blade on the slitting blade 12 needs to be replaced, the cylinder 131 is activated to move the two support blocks 132 away from the slitting blade 12, allowing for the disassembly and replacement of the external circular blade. The drive assembly 13 and the support assembly 14 work together to make the rotation of the slitting blade 12 more stable, without sacrificing speed when performing high-precision cutting of the film, resulting in faster film slitting efficiency.

[0032] Example 2, refer to Figures 5-6 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a reinforcing component for a precision slitting machine for film processing based on embodiment 1. This solves the problem of significant damage and easy tooth breakage of the deflection force gear 134 during the rotation of the blade holder. The reinforcing component includes a tension spring 20, which is fixedly connected inside the film slitting machine body 10. A reinforcing insert 21 is fixedly connected to one end of the tension spring 20 away from the film slitting machine body 10. A ball bearing 22 is movably connected inside the reinforcing insert 21. Two vertical plates 23 are fixedly connected to the inner sides of the two support blocks 132, and the length of the two upper vertical plates 23 is greater than the length of the two lower vertical plates 23. A reset component 24 is provided inside the film slitting machine body 10.

[0033] Specifically, when the upper vertical plate 23 moves, the ball bearing 22 moves on its outside, resulting in less friction and making the support block 132 move more smoothly and effortlessly.

[0034] Furthermore, the reset assembly 24 includes a winding roller 241, which is rotatably connected inside the film slitting machine body 10. Two pull ropes 242 are fixedly connected to the outside of the winding roller 241. Four steering rollers 243 are rotatably connected inside the film slitting machine body 10. The pull ropes 242 are movably connected to the outside of the steering rollers 243. One end of the pull rope 242 away from the winding roller 241 is fixedly connected to a reinforcing block 21. The reinforcing block 21 is inserted into the inside of two vertical plates 23. Ball bearings 22 are movably connected to the outside of the upper vertical plate 23.

[0035] In use, the tension spring 20 drives the reinforcing block 21 to move towards the slitting blade 12, causing the ball bearing 22 to abut against the outside of the outer vertical plate 23. When the two support blocks 132 move towards the center, they drive the vertical plate 23 to move. At this time, the slots in the four vertical plates 23 gradually approach each other until they overlap. When the two support blocks 132 abut, the four slots overlap, and the reinforcing block 21 corresponds to the slot. The tension spring 20 drives the reinforcing block 21 to insert into the slot. The reinforcing block 21 is inserted into the upper and lower vertical plates 23, further fixing the two support blocks 132 after they abut. This distributes the possible deflection force generated when the slitting blade 12 rotates, further reinforcing the rotation of the slitting blade 12, making it more stable, more precise, and avoiding deviation. The large rotational force could damage the gear 134 and cylinder 131. This device protects the cylinder 131 and gear 134, extending their service life. In the event of a temporary power outage or cylinder 131 failure, the reinforcing block 21 and vertical plate 23 work together to keep the two support blocks 132 in the same position, continuing to support the rotating slitting blade 12, providing better protection. When replacing the blade on the slitting blade 12, the two support blocks 132 need to be opened. Rotating the winding roller 241 drives the two pull ropes 242 to be wound and stored outside the winding roller 241. This causes the pull ropes 242 to pull the reinforcing block 21 away from the slitting blade 12 until the reinforcing block 21 is disengaged from the slot of the vertical plate 23. Then, the cylinder 131 can be activated to lower the two support blocks 132 and unfold them to replace the blade.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
