Description

Technical Field

[0001] This utility model belongs to the field of thin film production technology, and in particular relates to an adjustable thin film cutting device. Background Technology

[0002] Adjustable film cutting equipment is an automated device used for film processing. Its core function is to adapt to the cutting requirements of different films by adjusting parameters or structure.

[0003] Traditional film cutting equipment typically uses two blades to cut off the edges of the film during the conveying process to achieve the required size. Since film production usually involves films of different widths and needs to be cut into different sizes, the position of the blades needs to be adjusted. The traditional adjustment method usually involves disassembling the blades, moving them to the appropriate position, and fixing them. Manual adjustment can easily cause hand injuries to workers, and the equipment has many obstructions, making it inconvenient to operate. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable film cutting device. By setting an adjustment component, specifically by starting a motor to drive a threaded rod to rotate, two internal threaded blocks will drive two moving blocks to move, thereby adjusting the position of two arc-shaped cutting blades. This method can automatically adjust the distance between the two arc-shaped cutting blades according to different needs, thereby meeting different cutting requirements. It solves the problems of traditional adjustment methods, which usually involve disassembling the blades, moving them to the appropriate position and fixing them, while manual adjustment can easily cause hand injuries to workers, and the equipment has many obstructions, making it inconvenient to operate.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an adjustable film cutting device, including a base, and further comprising:

[0007] A feeding section, mounted on the top left side of the base, is used to place and unwind the film roller; and

[0008] The cutting section is mounted on the top right side of the base and is used to cut the film, and the cutting distance can be adjusted.

[0009] The feeding section includes two support plates mounted on the top of the base, with a feeding roller disposed between the two support plates. A collection box is positioned on the top of the base and is used to collect the cut film waste.

[0010] Furthermore, the cutting section includes a bracket fixedly connected to the top of the base, a baffle fixedly connected to the top of the bracket, a take-up roller provided on the right side inside the bracket, two placement protrusions installed on the right side of the inner wall of the bracket and the inner sides of the two support plates, and sliding grooves provided on the front and back of the bracket; the placement protrusions are used to support and position the feeding roller and the take-up roller.

[0011] A cutting assembly, mounted inside a support, is used for cutting a film.

[0012] A lifting assembly is mounted on the top of the bracket and is used to drive the cutting assembly to adjust its position by raising and lowering it.

[0013] A drive assembly, mounted on the right side of the bracket, for driving the take-up roller to rotate; and

[0025] This utility model has the following beneficial effects:

[0026] 1. This utility model, by setting an adjustment component, specifically, starts the second motor to drive the threaded rod to rotate, which in turn drives the two internal threaded blocks to move the two moving blocks, thereby adjusting the position of the two arc-shaped cutting blades. The two arc-shaped cutting blades move closer or further apart from each other. This method can automatically adjust the distance between the two arc-shaped cutting blades according to different needs, thereby meeting different cutting requirements, avoiding the situation of scratches caused to workers by manual operation, and enabling quick adjustment to improve efficiency.

[0041] The feeding section 2 includes two support plates 21 mounted on the top of the base 1, with a feeding roller 22 disposed between the two support plates 21. A collection box 314 is positioned on the top of the base 1 and is used to collect the cut film waste.

[0042] The cutting section 3 includes a bracket 31 fixedly connected to the top of the base 1. A baffle 311 is fixedly connected to the top of the bracket 31. A winding roller 312 is provided on the right side inside the bracket 31. Two placement protrusions 313 are installed on the right side of the inner wall of the bracket 31 and the inner side of the two support plates 21. Slide grooves 315 are provided on the front and back of the bracket 31.

[0043] Cutting assembly 32 is installed inside the support 31 and is used to cut the film.

[0044] Lifting component 33 is installed on the top of bracket 31 and is used to drive the cutting component 32 to lift and adjust its position.

[0045] Drive assembly 34, mounted on the right side of bracket 31, is used to drive the take-up roller 312 to rotate; and

[0048] Auxiliary roller 1 23 is rotatably connected to one side of the two support plates 21, auxiliary roller 2 36 is rotatably connected to the left side of the inside of the bracket 31, and two auxiliary rollers 37 are rotatably connected to the center of the bracket 31. Auxiliary roller 1 23, auxiliary roller 2 36 and auxiliary roller 3 37 are all used to assist in film conveying.

[0049] The cutting assembly 32 includes a fixed roller 321, an adapter roller 322 is provided below the fixed roller 321, two movable blocks 323 are slidably connected to the outside of the fixed roller 321, and an arc-shaped cutting blade 324 is bolted to the bottom of each of the two movable blocks 323. A limiting protrusion 325 is fixedly connected to the inside of the arc-shaped cutting blade 324, and a limiting groove 326 is opened at the bottom of the fixed roller 321.

[0050] The arc-shaped cutting blade 324 and the moving block 323 are both adapted to the outer side of the fixed roller 321. The limiting protrusion 325 on the arc-shaped cutting blade 324 slides in the limiting groove 326 to limit the arc-shaped cutting blade 324, making the movement of the arc-shaped cutting blade 324 more stable. Both ends of the adapter roller 322 are rotatably connected to the bracket 31.

[0051] The adjusting component 35 includes a threaded rod 351, with support blocks 352 rotatably connected to both the left and right sides of the threaded rod 351. The bottom of the support blocks 352 is fixedly connected to the surface of the fixed roller 321. The outer surface of the threaded rod 351 is provided with two opposite threads, and each of the two opposite threads on the outer surface of the threaded rod 351 is threadedly connected to an inner thread block 353. The bottom of the inner thread block 353 is fixedly connected to the top of the moving block 323. The support block 352 located in front is fixedly connected to a second motor 354. When the second motor 354 is started, it drives the threaded rod 351 to rotate, and the two inner thread blocks 353 will drive the two moving blocks 323 to move, thereby adjusting the position of the two arc-shaped cutting blades 324. The two arc-shaped cutting blades 324 move closer to or further away from each other. This method can automatically adjust the distance between the two arc-shaped cutting blades 324 according to different needs, thereby meeting different cutting requirements, avoiding the situation of scratches caused to workers by manual operation, and enabling quick adjustment to improve efficiency.

[0052] Among them, the output end of motor 354 is fixedly connected to threaded rod 351 through a coupling. When the threaded rod 351 rotates, it will drive two internal threaded blocks 353 to move closer or further away from each other, and drive two arc-shaped cutting blades 324 to move closer or further away from each other through two moving blocks 323.

[0053] The lifting assembly 33 includes a fixed frame 331 fixedly connected to the top of the bracket 31, an electric push rod 332 fixedly connected to the top of the fixed frame 331, a connecting frame 333 fixedly connected to the output end of the electric push rod 332, and connecting sliders 334 fixedly connected to both ends of the bottom of the connecting frame 333.

[0054] The fixed roller 321 is fixedly connected to two connecting sliders 334 on its front and back sides, respectively, and the two connecting sliders 334 slide in two grooves 315.

[0055] The drive assembly 34 includes a motor 341 fixedly connected to the back of the bracket 31, a gear 342 fixedly connected to the output end of the motor 341, and a gear 343 fixedly connected to the outside of the take-up roller 312. The gear 343 meshes with the gear 342. When the motor 341 starts, it drives the gear 342 to rotate. The gear 342 then drives the take-up roller 312 to rotate through the gear 343, thus winding up the cut film. At this time, the film is transmitted. After winding is completed, the take-up roller 312 can be lifted for disassembly, which is convenient for operation and can also ensure that the take-up roller 312 is smoothly transmitted.

[0056] When the take-up roller 312 is placed on the placement protrusion 313 on the bracket 31, the first gear 342 will mesh with the second gear 343, and the take-up roller 312 can be lifted for disassembly.

[0057] One specific application of this embodiment is:

[0058] In use, the feeding roller 22 is placed on the placement protrusion 313 on the support plate 21, and the film is passed through the auxiliary roller 1 23, then moved to the bottom of the auxiliary roller 2 36 on the left, then through the bottom of the auxiliary roller 3 37 on the left to the top of the adapter roller 322, and then out through the bottom of the auxiliary roller 3 37 on the right and wound onto the take-up roller 312. The take-up roller 312 is placed on the placement protrusion 313 on the right side of the bracket 31, and the gear 2 343 will mesh with the gear 1 342. After the film is wound, the electric push rod 332 is activated to drive the connecting frame 333 to move downward. 3. The fixed roller 321 will move downward through the two connecting sliders 334, so that the arc-shaped cutting blade 324 contacts the surface of the adapter roller 322 and cuts the film. Then the electric push rod 332 stops, and then the motor 1 341 is started to drive the gear 1 342 to rotate counterclockwise. The gear 1 342 drives the take-up roller 312 to rotate clockwise through the gear 2 343. At this time, the film will be transmitted. During the transmission process, the two arc-shaped cutting blades 324 will cut the edge of the film, so that the film is cut into a fixed size. The film with the cut edge will enter the collection box 314 for collection.

[0059] When the film cutting is completed and the cutting size needs to be adjusted, the motor 354 is started to drive the threaded rod 351 to rotate. The two internal threaded blocks 353 will then drive the two moving blocks 323 to move, thereby adjusting the position of the two arc-shaped cutting blades 324. The two arc-shaped cutting blades 324 will move closer or further apart from each other, and the arc-shaped cutting blades 324 will drive the limiting protrusion 325 to slide in the limiting groove 326, making the movement of the arc-shaped cutting blades 324 more stable. This method can automatically adjust the distance between the two arc-shaped cutting blades 324 according to different needs, thereby meeting different cutting requirements. The arc-shaped cutting blades 324 and the moving blocks 323 are connected by bolts. When the arc-shaped cutting blades 324 need to be replaced, the bolts are removed and the arc-shaped cutting blades 324 are pulled down for quick disassembly, which facilitates subsequent maintenance.
