The development of these equipment tends to be intelligent and multifunctional, especially for PVC sheet cutting, which is an indispensable part of PVC sheet manufacturing.

[0003] In the prior art, cutting equipment usually includes a cutting mechanism, a positioning mechanism, etc., but these mechanisms often work separately and lack effective coordination. For example, most traditional cutting mechanisms rely only on manual or simple electrical control for operation, and the cutting accuracy and stability are greatly limited. The connection between the positioning mechanism and the cutting mechanism often adopts mechanical connection or simple transmission device, which fails to achieve intelligent real-time adjustment in terms of accuracy.

[0004] Regarding the above-mentioned prior art solutions, firstly, the existing technology has low cutting accuracy and unstable workpiece positioning caused by error accumulation, which makes it difficult to meet the requirements of modern manufacturing industry for accuracy and efficiency. Secondly, there is a lack of effective compensation mechanism, which leads to large cutting errors, affecting production quality and efficiency. There is no transmission compensation mechanism to deal with thickness changes. Finally, the temperature control and cleaning systems in the prior art are mostly independent and not linked to the cutting process in real time, which may affect the performance of the equipment due to overheating during operation, or cause system instability due to waste and dust accumulation. Therefore, those skilled in the art provide a PVC sheet cutting device with automatic positioning function to solve the problems raised in the above background. Summary of the invention

[0050] Working principle of the present invention: First, the first electromagnetic block 112 is energized to attract and drive the first magnetic block 113, thereby driving the spacing sliding block 114, and linearly displacing the sliding groove 1161 with equal horizontal spacing, so as to achieve the purpose of controlling the width of the sheet, and the first elastic member 115 pulls the spacing sliding block 114 to move, and ensures that the spacing sliding block 114 can return to the initial position after each cutting, so as to improve the cutting efficiency and accuracy, and adjust the position of the compensation block 317 through the electric compensation slide rail 316, and then control the second magnetic block 3110 to drive through the second electromagnetic block 319. The linear displacement of the rotating shaft 312 changes the height of the rotating shaft 312, thereby achieving the height change of the Mecanum wheel 311 to adapt to sheets of different thicknesses. First, the offset position of the sheet can be changed during the transmission process. Second, the relative friction formed by the rotation of the second belt assembly 23 and the Mecanum wheel 311 can be used to compensate for the transmission to achieve the purpose of improving the accuracy. Third, a group of sheets of different widths can be simultaneously transmitted through multiple sets of transmission compensation assemblies 31 to prevent edge collision and warping. Then, the longitudinal cutter 123 can be used to achieve the purpose of single The purpose of simultaneously cutting plates of different widths is to improve work efficiency; secondly, the pressing block 134 slides relative to the pressing frame 131, and the knife frame 122 pulls the transmission elastic member 135 to drive the pressing block 134 to move, and the pressing block 134 and the anti-damage elastic member 133 form a buffering and fixed pressing effect on the sheet, and then longitudinal cutting is performed to improve cutting stability and prevent damage; finally, the pressing block 134 moves up and down to drive the transmission rack 137, thereby driving the first thorn gear 138 to transmit to the second thorn gear 139, so that the second thorn The gear 139 drives the transmission gear 5121 to transmit to the transmission gear rod 511, driving the control plate 59 to squeeze the liquid between the control valve block 57.
