[0025] Example

[0026] Please see Figure 1-4This utility model relates to a plastic film cutting device, comprising a support assembly 100, a transverse moving assembly 200 mounted on the upper part of the support assembly 100, and a longitudinal moving assembly 300 adapted to the transverse moving assembly 200. The support assembly 100 includes a side plate 101, a film roll 104 mounted on the end of the side plate 101 via a bushing 103, and guide rollers 105 distributed between the side plates 101. The film roll 104 is used to load the plastic film roll and is fixed to the end of the side plate 101 via the bushing 103, ensuring that the film can be smoothly unfolded and transported to the cutting position. The transverse moving assembly 200 includes a support plate 201 fixed to the other end of the side plate 101, a transverse driving rod 204 disposed between the support plates 201, and a longitudinal moving assembly 300. The moving rod 204 is fitted with a threaded seat 205, and a vertical plate 207 is fixed to the outside of the threaded seat 205. The threaded seat 205 moves along the transverse driving rod 204, thereby realizing the transverse displacement of the vertical plate 207, so that the cutter can be accurately positioned laterally to adapt to the cutting requirements of different widths. The longitudinal moving component 300 includes a threaded kit 304 fixed to the middle position of the outside of the vertical plate 207, a vertical driving rod 303 fitted with the threaded kit 304, and a cutter holder 307 fixed to the lower end of the vertical driving rod 303. The up and down movement of the vertical driving rod 303 adjusts the height of the cutter holder 307 to complete the cutting operation of the plastic film, ensuring the linear movement of the cutter holder 307 in the vertical direction, and further enhancing the accuracy of the cutting process.

[0027] Specifically, a drive motor 202 is fixed to the outside of the support plate 201. The output end of the drive motor 202 is connected to the transverse drive rod 204. The transverse drive rod 204 is movably connected to the support plate 201 via the bearing seat 203. A limit seat 206 is fixed at the corner of the back of the vertical plate 207. A guide rod 208 is inserted inside the limit seat 206. The two ends of the guide rod 208 are respectively fixed to the inner side of the support plate 201. When the drive motor 202 is started, its output end drives the transverse drive rod 204 to rotate, thereby realizing the transverse reciprocating drive of the thread seat 205. The vertical plate 207, which is fixed relative to the thread seat 205, moves accordingly. Finally, the position adjustment of the tool holder 307 is completed by the transverse position movement of the longitudinal moving component 300. The guide rod 208 achieves the movement balance of the vertical plate 207 through the limit seat 206.

[0028] Limiting rods 305 are fixed at both ends of the upper side of the tool holder 307. Limiting kits 306 are sleeved on the outside of the limiting rods 305. The limiting kits 306 are symmetrically fixed to the outer side of the vertical plate 207. A top plate 302 is fixed to the top of the limiting rods 305. A second drive motor 301 is installed on the top of the top plate 302. The output end of the second drive motor 301 is adapted to the upper end of the vertical drive rod 303. When the second drive motor 301 is started, its output end drives the vertical drive rod 303 to rotate, and under the action of the threaded kit 304, it achieves lifting and lowering. The limiting kits 306 are used to achieve the movement balance of the tool holder 307 through the limiting rods 305.

[0029] Furthermore, a mounting plate 102 is fixed to the lower outer edge of the side plate 101. The mounting plate 102 has a mounting groove for fastener installation. The mounting plate 102 is fixed to the outer mounting surface by fasteners, thereby realizing the installation and fixation of the device. The guide rollers 105 are distributed along the direction of the side plate 101. The guide rollers 105 are arranged parallel to the film roll 104, and the guide rollers 105 are distributed up and down about the axis of the film roll 104, which helps to guide and adjust the position of the plastic film and ensure that it remains flat and wrinkle-free before entering the cutting area.
