[0002] Laminating film, also known as thermal laminating film, card protection film, laminating film, or overlaminate film, is a great choice for laminating photos and documents. Laminating film requires heating in a laminating machine. Different thicknesses require different laminating temperatures, which are influenced by the laminating machine's pressure and speed, as well as the film's thickness. Laminating film offers advantages such as moisture-proofing, dustproofing, and fading resistance, protecting documents and photos for long-term use. It can be cut as needed before and after laminating to ensure the film fits the product perfectly.

[0003] The existing cutting device for plastic film processing has the functions of cutting, hot molding, cold molding, etc., and cuts the plastic film by sliding the cutter. However, the position of the plastic film needs to be manually adjusted before cutting so that it is perpendicular to the cutter, otherwise the cutting will be skewed. Manual position adjustment is too time-consuming and has poor accuracy. Due to the lack of pressure, the plastic film may move and be misplaced during cutting. Utility Model Content

[0004] The purpose of the utility model is to provide a cutting device for processing plastic film, which can block the plastic film on both sides through the positioning plate, so that the plastic film is kept perpendicular to the cutter during the cutting process, preventing the plastic film from deflecting, and can adapt to plastic films of different sizes and widths, saving time and labor.

The positioning plate 2 is symmetrically slidably assembled on the top of the laminator 1. A sliding groove 101 is symmetrically opened on the top of the laminator 1. The inner wall of the sliding groove 101 is mirror-image-connected with a rack 204 in sliding connection. One end of the rack 204 is fixedly connected to the positioning plate 2. A vertical transmission mechanism for meshing with the rack 204 is assembled inside the laminator 1; the vertical transmission mechanism includes a sleeve rod 207 and a sliding rod 205. The sleeve rod 207 is rotatably assembled inside the laminator 1. The interior of the laminator 1 and located on one side of the sleeve rod 207 is rotatably connected to the rotating shaft 206, the outer wall of the sliding rod 205 is symmetrically fixedly connected to the side strip 211, the sliding rod 205 is slidably connected to the inner wall of the sleeve rod 207 through the side strip 211, the rotating shaft 206 and the outer wall of the sleeve rod 207 are fixedly connected to the gear 2 209, the two racks 204 are respectively meshed with the gear 2 209, the rotating shaft 206 and the outer wall of the sleeve rod 207 and located on one side of the gear 2 209 are fixedly connected to the gear 1 208, and the two gears 1 208 are meshed.

[0022] According to the above structure, the sliding rod 205 is rotated, and the sliding rod 205 drives the sleeve rod 207 to rotate through the side bar 211, and the sleeve rod 207 drives gear 1 208 and gear 2 209 to rotate. The gear 1 208 on the outer wall of the sleeve rod 207 drives the gear 1 208 on the outer wall of the rotating shaft 206 to rotate, thereby rotating the gear 2 209 on the outer wall of the rotating shaft 206. The two gears 209 respectively drive the rack 204 to move in the sliding groove 101, and the rack 204 drives the positioning plate 2 to move to adapt to plastic films of different sizes, and stay on both sides of the plastic film to block it.

[0023] Refer to the attached Figure 1 、 Figure 4-5The inner rotation of the positioning plate 2 is connected to the rotating rod 202, and the outer wall of the rotating rod 202 is fixedly connected to the baffle 215 at the bottom of the positioning plate 2. The positioning plate 2 is elastically connected to the baffle 215 through a bending spring 216. The outer wall of the rotating rod 202 is fixedly connected to the clamping rod 201 at the top of the positioning plate 2. One end of the sliding rod 205 is rotatably connected to the trapezoidal plate 1 212 on one side of the sleeve rod 207. The inner wall of the laminator 1 is fixedly connected to the connecting pipe 210, and the inner wall of the connecting pipe 210 is slidably connected to the square rod 213. The square rod 213 is fixedly connected to the trapezoidal plate 1 212. The internal sliding assembly of the laminator 1 is equipped with a push rod 203, one end of the push rod 203 is fixedly connected to the trapezoidal plate 214, the trapezoidal plate 214 is movably fitted with the trapezoidal plate 1 212, and the other end of the push rod 203 is movably fitted with the baffle 215.

[0024] According to the above structure, by pushing the sliding rod 205 into the interior of the laminator 1, the sliding rod 205 moves the trapezoidal plate 1 212. Since the connecting pipe 210 is slidably connected to the square rod 213, the square rod 213 is fixedly connected to the trapezoidal plate 1 212, and the trapezoidal plate 1 212 is rotatably connected to the sliding rod 205, when the sliding rod 205 and the sleeve rod 207 rotate, the trapezoidal plate 1 212 will not rotate. When the trapezoidal plate 1 212 moves, it pushes the trapezoidal plate 214 to both sides, and at the same time, the square rod 213 is inserted into the connecting pipe 210. The second shaped plate 214 pushes the push rod 203 toward the baffle 215, and the baffle 215 contracts through the bending spring 216, and drives the clamping rod 201 to rotate so that it contacts the top of the laminator 1, so that the plastic film can be clamped and compacted; the utility model can block the plastic film on both sides through the positioning plate 2, so that the plastic film remains perpendicular to the cutter during the cutting process, preventing the plastic film from deflecting, and can adapt to plastic films of different sizes and widths, which is more time-saving and labor-saving. At the same time, it can also compact and clamp the plastic film to prevent the plastic film from bulging and dislocating during cutting.

[0025] The working principle of the present invention is as follows: the sliding rod 205 is rotated, and the sliding rod 205 drives the sleeve rod 207 to rotate through the side bar 211, and the sleeve rod 207 drives the gear 1 208 and the gear 2 209 to rotate, and the gear 1 208 on the outer wall of the sleeve rod 207 drives the gear 1 208 on the outer wall of the rotating shaft 206 to rotate, thereby rotating the gear 2 209 on the outer wall of the rotating shaft 206, and the two gears 209 respectively drive the rack 204 to move in the sliding groove 101, and the rack 204 drives the positioning plate 2 to move to adapt to plastic films of different sizes, and stays on both sides of the plastic film to block it, and by pushing the sliding rod 205 toward the inside of the laminating machine 1, the sliding rod 205 The trapezoidal plate 1 212 is moved. Due to the sliding connection between the connecting pipe 210 and the square rod 213, the fixed connection between the square rod 213 and the trapezoidal plate 1 212, and the rotation connection between the trapezoidal plate 1 212 and the sliding rod 205, when the sliding rod 205 and the sleeve rod 207 rotate, the trapezoidal plate 1 212 will not rotate. When the trapezoidal plate 1 212 moves, it will push the trapezoidal plate 214 to both sides. At the same time, the square rod 213 is inserted into the connecting pipe 210, and the trapezoidal plate 214 pushes the push rod 203 toward the baffle 215. The baffle 215 is contracted by the bending spring 216, and drives the clamping rod 201 to rotate so that it contacts the top of the laminating machine 1, so that the laminating film can be clamped and compacted.
