[0017] Compared with the prior art, the utility model has at least the following beneficial effects:

[0018] In the above scheme, by setting a multi-directional cutting mechanism, the staff can start the motor three to rotate the transmission screw rod three inside the sliding frame two, so that the screw rod sliding sleeve three that acts on the screw rod will carry the assembly frame and the electric hot knife that is indirectly connected to the lower part thereof to cooperate with the guide rod two to perform vertical displacement. This adjustment method can be used to adjust the area of ​​the electric hot knife on the sheet to be cut at a fixed distance, and can also directly use the cylinder two to make the electric hot knife descend and cut at a fixed distance along the front and back directions of the sheet. When it comes to left and right cutting, the staff can start the motor two to rotate the transmission screw rod two. At this time, the screw rod sliding sleeve two that acts on the screw rod will carry the sliding frame two and its internal related components to cooperate with each other. Guide rod 1 guides the overall left-right displacement. At this moment, after cooperating with the above-mentioned adjustment of the area on the sheet to be cut at a fixed distance by the electric heating knife, the effect of the electric heating knife cutting the sheet horizontally can be indirectly achieved by starting cylinder 2. It is worth mentioning that since the blade surface of the electric heating knife only faces one side, when it involves adjusting and cutting the sheet in the front-back and left-right directions, the personnel can start cylinder 3 to move the fixed block on one side above the sliding rack frame. At this time, the sliding rack frame can rotate with the gear and the middle rotating rod according to the guide meshing of the sliding frame. Since the end of the rotating rod is connected to the connecting frame, the above-mentioned structure can achieve the beneficial effect of adaptive adjustment with the connecting frame and its bottom end.

[0019] By setting a limit flattening mechanism, the staff will place the PET sheet to be processed on the processing table in advance, and then start the symmetrical cylinder 1 inside the lower mounting frame to make the connecting plate and the pressing frames 1 and 2 descend to the same level. At this time, the pressing frames 1 and 2 will both press on the upper side of the PET sheet, among which the pressing frame 1 is used to fix one end of the PET sheet, and the pressing frame 2 can be started by the motor 1, in conjunction with the threaded transmission of the transmission screw rod 1 and the screw rod sleeve 1 and the guide groove to move along the surface of the PET sheet. Since a scraper is fixed at the bottom end of the inner part of the pressing frame 2, the scraper can use horizontal displacement to achieve auxiliary flattening of the sheet surface at this moment, avoiding the influence of wrinkles and offset on the subsequent cutting.

[0020] By setting up a smoke treatment mechanism, when the electric hot knife is cutting the thin slices, since there is a heating wire in the electric hot knife, although the burrs of the slices can be reduced during heating and cutting, some smoke may be generated. At this time, the staff can start the smoke exhaust fan, and the air duct at one end of the smoke exhaust fan and the smoke exhaust hood can suck the smoke in and discharge it from the other pipe into the purification box, and then be discharged after purification in the purification box.

A connecting frame 763 is fixed at the end, and a sliding rack frame 764 is meshed with one side of the gear 762. The sliding rack frame 764 and the gear 762 are meshed and transmitted. A sliding frame 765 for the sliding rack frame 764 to move is fixed on one side of the assembly frame 75, and a fixing block 766 is fixed on the upper side of one side of the sliding rack frame 764. A cylinder three 767 is fixedly installed on one side of the assembly frame 75, and the top of the cylinder three 767 is connected to the fixing block 766, and the fixing block 766 is fixedly connected to the upper side of the sliding rack frame 764.

This adjustment method can be used to adjust the area of ​​the electric heating knife 77 on the sheet to be cut at a fixed distance, and can also directly use the cylinder 71 to make the electric heating knife 77 descend and cut along the sheet in the front and back directions at a fixed distance. When it comes to left and right cutting, the personnel can start the motor 742 to rotate the transmission screw rod 741.

The facing angle of the smoke exhaust hood 85 is directly facing the end of the electric hot knife 77. When the electric hot knife 77 is cutting the thin slice, since there is a heating wire in the electric hot knife 77, although the burrs of the thin slice can be reduced during heating and cutting, some smoke may be generated.

At this time, the pressing frame 1 53 and the pressing frame 2 57 will press on the upper side of the PET sheet, wherein the pressing frame 1 53 is used to fix one end of the PET sheet, and the pressing frame 2 57 can be started by the motor 1 55, cooperate with the threaded transmission of the transmission screw 1 54 and the screw sleeve 1 56 and the guide of the guide groove 4 to move along the surface of the PET sheet. Since the inner bottom end of the pressing frame 2 57 is fixed with a scraper 58, at this moment the scraper Plate 58 can use horizontal displacement to achieve auxiliary flattening of the surface of the thin slice to avoid the influence of wrinkles and offset on subsequent cutting. Secondly, the staff can start motor 3 747 to rotate the transmission screw 3 746 inside the sliding frame 2 744, so that the screw sleeve 3 748 that acts on the screw will carry the assembly frame 75 and the electric hot knife 77 indirectly connected to the lower part to cooperate with the guide rod 2 749 for vertical displacement.

At this time, the screw rod sleeve 2 743 acting on the screw rod will lead the sliding frame 2 744 and its internal related components to cooperate with the guide rod 1 745 to move left and right as a whole. At this moment, after adjusting the area of ​​the electric heating knife 77 to be cut at a fixed distance on the thin sheet, the cylinder 2 71 can be used to start the electric heating knife 77 to indirectly achieve the effect of horizontally cutting the thin sheet. It is worth mentioning that since the blade surface of the electric heating knife 77 only faces one side, when it involves adjusting and cutting the thin sheet in the front and back, left and right directions, the personnel can start the cylinder 3 767 to move the fixed block 766 on one side of the sliding rack frame 764. At this time, the sliding rack frame 764 is moved. The rack frame 764 can rotate with the gear 762 and the middle rotating rod 761 according to the guide of the slide 765. Since the end of the rotating rod 761 is connected to the connecting frame 763, the above structure can achieve the beneficial effect of adaptive adjustment of the connecting frame 763 and its bottom end. Finally, since there is a heating wire in the electric hot knife 77, although the burrs of the thin slices can be reduced during heating and cutting, some smoke may be generated. At this time, the personnel can start the smoking fan 83. The air duct 84 at one end of the smoking fan 83 and the smoking hood 85 can suck in the smoke and discharge it from the other pipe into the purification box 86, and the purification box 86 purifies it and then discharges it.
