[0030] The positioning member 2 includes a support plate A21 and a support plate B22 fixed on the surface of the cutting table 1. A sleeve rod 24 is provided on the inner side of the support plate A21 and the support plate B22. A positioning ring 26 is movably sleeved on the surface of the sleeve rod 24. There are two groups of positioning rings 26. The bottom of the positioning ring 26 is fixedly connected with a nut B27. The surfaces of the sleeve rod 24 and the positioning ring 26 are both provided with positioning holes 29. The positioning holes 29 on the surface of the sleeve rod 24 are arranged equidistantly. The positioning ring 26 is connected to the sleeve rod 24 by a bolt B28, and the bolt B28 extends through the positioning hole 29 to the bottom of the positioning ring 26 and is threadedly connected to the nut B27. The setting of the positioning hole 29 can be used for the two groups of positioning. The position of the positioning ring 26 can be adjusted to adapt to the rolled PET plastic sheets of different lengths, and the PET plastic sheets can be limited by adjusting the gap between the two sets of positioning rings 26, so as to prevent the PET plastic sheets from being offset during the rotation process. The positioning member 2 is located on the surface of the cutting table 1, the sleeve 3 is located on one side of the positioning member 2, the conveying member 4 is located on the other side of the sleeve 3 and away from the side of the positioning member 2, the cutting table 5 is located on one side of the conveying member 4 and away from the side of the positioning member 2, and the cutting table 5 includes a frame, a hydraulic cylinder fixed on the top of the frame, and the output end of the hydraulic cylinder extends to the inside of the frame and is connected to a cutter.

[0031] The support plate A21 is located on one side of the support plate B22, and both the support plate A21 and the support plate B22 are configured to be L-shaped.

[0032] A fixed shaft 23 is fixedly connected inside the support plate B22. One end of the sleeve rod 24 is located inside the support plate B22 and is movably connected through the fixed shaft 23. The fixed shaft 23 can facilitate the movement of the sleeve rod 24, thereby facilitating the installation of the rolled PET plastic sheet.

[0033] A nut A251 is fixedly connected to the bottom of the support plate A21. The other end of the sleeve rod 24, which is away from the support plate B22, is located inside the support plate A21 and is connected by a bolt A25. The bolt A25 extends to the bottom of the support plate A21 and is threadedly connected to the nut A251. The setting of the bolt A25 and the nut A251 can lock the sleeve rod 24 to prevent it from moving during normal operation.

[0034] During use, pull the sleeve rod 24 to rotate it around the fixed axis 23 as the center to the appropriate area, then put the rolled PET plastic sheet on the surface of the sleeve rod 24, then put a group of positioning rings 26 on the surface of the sleeve rod 24 until the PET plastic sheet is stuck, then pass the bolt B28 through the positioning hole 29, and extend to the bottom of the positioning ring 26 and threadedly connected with the nut B27. After the installation is completed, push the sleeve rod 24 to rotate it around the fixed axis 23 as the center again to the inside of the support plate A21, then pass the bolt A25 through the bottom of the support plate A21 and threadedly connect it with the nut A251, and the installation operation is completed. When replacing, the operation is the same as above.

[0035] When installing the PET plastic sheet, the position of the two sets of positioning rings 26 can be adjusted according to the length of the PET plastic sheet. First, the bolt B28 is screwed in the opposite direction to separate it from the nut B27 at the bottom of the positioning ring 26. Then, the positioning ring 26 is moved to a suitable position along the surface of the sleeve rod 24, and the positioning ring 26 is aligned with the positioning hole 29 on the surface of the sleeve rod 24. The bolt B28 is passed through the bottom of the positioning ring 26 and is threadedly connected with the nut B27. This can achieve the purpose of positioning PET plastic sheets of different widths. By positioning the two sides of the PET plastic sheet, the PET plastic sheet can be prevented from being offset when rotating, and the PET plastic sheet is further stabilized during cutting.

[0040] A slide bar 454 is fixedly connected to the inner side of the limit frame 451, and slide grooves 456 are provided on both sides of the positioning shaft 44. The slide grooves 456 are located on the surface of the slide bar 454 and are movably connected thereto. The slide grooves 456 and the slide bar 454 can make the positioning shaft 44 more stable when it is raised or lowered.

[0041] One end of the positioning shaft 44 is fixedly connected to a pull rod 458, and the pull rod 458 is set to be L-shaped. One end of the pull rod 458 is movably sleeved with a plug 457, and a retaining ring 459 is fixedly connected to the surface of the plug 457. A magnet 4591 is installed on the inner side of the retaining ring 459, and the magnet 4591 is magnetically connected to the pull rod 458. One end of the plug 457 is fixedly connected to a limiting ring, and a magnet 4591 is also installed on the inner side of the limiting ring, which is magnetically connected to the pull rod 458. The setting of the limiting ring and the retaining ring 459 can prevent the plug 457 from detaching from the pull rod 458, and the setting of the magnet 4591 can make the plug 457 more stable during use or non-use. When the plug 457 is located inside the socket 455, the magnet 4591 can achieve the purpose of locking.

[0042] The surface of the limiting frame 451 is provided with plug holes 455, and the plug holes 455 are arranged at equal intervals.

[0043] During use, after the PET plastic sheet is installed, its starting end is stretched and moved along the surface of the sleeve 3 to fit with the sleeve 3, and the starting end of the PET plastic sheet is pulled to be located on the surface of the roller A42. During this period, the pull rod 458 can be pulled to drive the positioning shaft 44 and the roller B43 to rise through the slide bar 454 and the slide groove 456, and the spring 452 is stretched by the adapter block 453. The pull rod 458 can be pulled to a suitable height according to the thickness of the PET plastic sheet, and then the plug 457 is pushed to fit with the adjacent socket 455 until the magnetic block 4591 on the inner side of the limit ring is magnetically connected to the pull rod 458, and then the starting end of the PET plastic sheet is placed on the roller A 42, and pull the plug 457 to separate it from the socket 455, and cancel the magnetic connection between the magnetic block 4591 on the inner side of the limit circle and the pull rod 458. Through the weight of the roller B43 itself, it can directly drop and squeeze the spring 452 to make it fit with the PET plastic sheet, and then push the plug 457 again to make it fit with the adjacent socket 455 until the magnetic block 4591 on the inner side of the limit circle is magnetically connected with the pull rod 458, and the operation is completed. Then, the motor 41 is started to drive the roller A42 to rotate, so as to achieve the purpose of conveying the PET plastic sheet, and further achieve the purpose of being able to adapt to PET plastic sheets of different thicknesses for cutting operations, and further save the equipment purchase cost and floor space.
