Description

Technical Field

[0001] This utility model relates to the field of aluminum paper cutting technology, and in particular to a high-efficiency film cutting device for the production of PET easy-tear aluminum paper. Background Technology

[0002] PET easy-tear aluminum foil is a functional material made by combining PET (polyethylene terephthalate) film and aluminum foil. It combines the high transparency and good mechanical properties of PET with the barrier properties and light-blocking properties of aluminum foil, and is widely used in packaging for tobacco, food, and pharmaceuticals. To meet the needs of different packaging specifications, PET easy-tear aluminum foil requires precise cutting during the production process using a film-cutting device. As a key piece of equipment on the PET easy-tear aluminum foil production line, the main function of the film-cutting device is to longitudinally cut the roll of composite aluminum foil to a set size to form narrow strips of aluminum foil that meet the requirements.

[0003] In the traditional longitudinal cutting process of PET easy-tear aluminum foil production, the film cutting device used has significant technical defects. When it is necessary to adjust the spacing of multiple cutting components to meet different cutting requirements, operators often need to repeatedly disassemble and reassemble multiple bolts to release the fixing of the cutting components and fix the adjusted cutting components, thereby completing the position adjustment of the cutting components. This adjustment method is not only cumbersome and time-consuming, but also greatly reduces production efficiency. Therefore, this application proposes a high-efficiency film cutting device for PET easy-tear aluminum foil production to solve the above problems. Utility Model Content

[0004] The main objective of this invention is to provide a high-efficiency film cutting device for the production of PET easy-tear aluminum paper, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-efficiency film cutting device for producing PET easy-tear aluminum foil includes a support frame. Two support plates are symmetrically fixedly installed on the upper end of the support frame. A square rod is fixedly installed on the inner end of each support plate. A threaded adjusting component is rotatably installed inside the square rod. The threaded adjusting component consists of a rotating handle and a lead screw. Two lead screws are symmetrically fixedly installed at both ends of the rotating handle. Two adjustable cutting components are symmetrically installed on the square rod and the threaded adjusting component. Each adjustable cutting component consists of a cylinder, a cutting head, a square frame, a connecting plate, and a square column. The cutting head is fixedly installed at the lower end of the piston rod of the cylinder. The square frame is fixedly installed at the upper end of the cylinder. Two connecting plates are symmetrically fixedly installed on the inner wall of the square frame. The square column is located inside the square frame and is fixedly connected to the two connecting plates.

[0007] Preferably, an unwinding assembly is fixedly installed at the rear end of the equipment bracket, and a winding assembly is fixedly installed at the front end of the equipment bracket.

[0008] Preferably, a support roller is rotatably mounted on the two support plates, and the support roller is located below the adjustable cutter.

[0009] Preferably, a limiting guide groove is provided inside the square rod, four through grooves are symmetrically provided on the end face of the square rod, and four connecting guide grooves are symmetrically provided on the end face of the square rod. The four connecting guide grooves are located on the left and right sides of the through grooves, and the limiting guide groove is connected to the through grooves and the connecting guide grooves. Two limiting grooves are symmetrically provided on the inner walls of the left and right sides of the limiting guide groove.

[0010] Preferably, the rotating handle on the threaded adjustment component is rotatably mounted in the limiting guide groove, and the rotating handle simultaneously passes outward through the through groove, while the lead screw is rotatably mounted in the limiting guide groove and the limiting groove.

Two adjustable cutting components 5 are symmetrically installed on the square rod 3 and the threaded adjusting component 4. Each adjustable cutting component 5 consists of a cylinder 14, a cutting head 15, a square frame 16, a connecting plate 17, and a square column 18. The cutting head 15 is fixedly installed at the lower end of the piston rod of the cylinder 14, the square frame 16 is fixedly installed at the upper end of the cylinder 14, and there are two symmetrical connecting plates 17. The square column 18 is fixedly installed on the inner wall of the square frame 16 and is located inside the square frame 16. The square column 18 is fixedly connected to two connecting plates 17. By setting the square rod 3, the threaded adjustment part 4, and the adjustable cutting part 5 composed of the cylinder 14, the cutting head 15, the square frame 16, the connecting plate 17 and the square column 18, the operator can directly rotate the rotating handle 12 and use the rotation of the lead screw 13 to drive the square column 18 to move in the limiting guide groove 8. Then, the square frame 16 is driven to slide on the square rod 3 through the connecting plate 17, so as to realize the rapid adjustment of the distance between the two adjustable cutting parts 5. There is no need to repeatedly disassemble and assemble the bolts. The operation is simple, time-saving and labor-saving, which greatly improves the efficiency of adjusting the position of the adjustable cutting part 5 and effectively meets the high-efficiency cutting needs of PET easy-tear aluminum paper production of different specifications.

[0021] Specifically, an unwinding assembly 6 is fixedly installed at the rear end of the equipment bracket 1, and a winding assembly 7 is fixedly installed at the front end of the equipment bracket 1. A support roller 20 is rotatably installed on each of the two support plates 2, and the support roller 20 is located below the adjustable cutting piece 5. A limiting guide groove 8 is opened inside the square rod 3. Four through grooves 9 are symmetrically opened on the end face of the square rod 3, and four connecting guide grooves 10 are also symmetrically opened on the end face of the square rod 3. The four connecting guide grooves 10 are located on the left and right sides of the through grooves 9, and the limiting guide groove 8 is interconnected with the through grooves 9 and the connecting guide grooves 10. Two limiting grooves 11 are symmetrically opened on the inner walls of the left and right sides of the limiting guide groove 8. The rotating handle 12 on the threaded adjustment piece 4 is rotatably installed in the limiting guide groove 8. Handle 12 passes outward through slot 9. Lead screw 13 is rotated and installed in limit guide rail slot 8 and limit slot 11. Square frame 16 on adjustable cutting piece 5 is movably sleeved on square rod 3.

One end of aluminum paper is led out from unwinding assembly 6, supported and flattened by support rollers 20 on two support plates 2, and placed below adjustable cutting piece 5. Then, this end of aluminum paper is wound up on winding assembly 7. Next, according to the required cutting specifications (aluminum paper width), the operator rotates the rotating handle 12 on the threaded adjustment component 4. The rotating handle 12 drives the lead screws 13 at both ends to rotate within the limiting guide groove 8 and the limiting groove 11. When the lead screws 13 rotate, the square column 18 connected to the lead screws 13 through the screw hole 19 moves within the limiting guide groove 8. The movement of the square column 18 drives the square frame 16 to slide on the square rod 3 via the connecting plate 17. At the same time, the square frame 16 drives the cylinder 14 and the cutting head 15 to move, thereby adjusting the distance between the two adjustable cutting components 5. After the adjustment is completed, the cylinder 14 is started, and its piston rod drives the cutting head 15 to move downward to contact the aluminum paper on the support roller 20. At the same time, the winding assembly 7 is started to wind up the aluminum paper on the unwinding assembly 6. During the winding and moving process, the cutting head 15 in contact with the aluminum paper will complete the cutting of the aluminum paper.
