Referring to fig. 1, 2 and 4, an embodiment of the present invention provides a full-automatic plastic winding machine, including a turnover winding machine 1, a feeding cutting device 2 and an electric control mechanism 3; the feeding cutting device 2 comprises a first clamping device 21 and a second clamping device 22 which can be lifted synchronously, and the first clamping device 21 and the second clamping device 22 clamp a winding shaft 11 of the turnover winding machine 1 after being lifted and gathered; a cutting mechanism 23 is also provided on the second clamping device 22. A synchronizing mechanism 4 is also arranged in the feeding and cutting device 2.

Specifically, 1 coil stock of upset rolling machine, material loading cutting device 2 carries out the coil stock to plastic sheet, and whole process is controlled through electrical control mechanism 3, realizes automaticly. When the first roll is rolled, after manual rolling is needed, the material is directly fed through the first clamping device 21 and the second clamping device 22 when the second roll is rolled. When the material is newly started, the direct current motor controlled turnover winding machine 1 contacts the first clamping device 21 and the second clamping device 22, the rotating speed changes, and the plastic sheets are scratched. After the synchronous mechanism 4 is used, the plastic sheets and the overturning winding machine 1 are synchronized in rotating speed, so that relative movement is prevented, and the plastic sheets are scraped.

Referring to fig. 1, 2 and 4, in an alternative embodiment, the synchronizing mechanism 4 includes a first cylinder 41 disposed in the feeding and cutting device 2, a fixing seat 42 mounted on the first cylinder 41, and a synchronizing shaft 43 rotatably mounted on the fixing seat 42. A rubber mat cover 431 is concentrically sleeved outside the synchronous rotating shaft 43.

Specifically, the first cylinder 41 drives the synchronous rotating shaft 43 to ascend so that the sheet of the roll-over winder 1 and the synchronous rotating shaft 43 rotate synchronously. The cushion cover 431 prevents the plastic sheet from being excessively squeezed to scratch the plastic sheet.

Referring to fig. 5, in an alternative embodiment, the electric control mechanism 3 includes a power module 31, a traverse control module 32, a synchronous shaft lifting module 33, a lifting cylinder control module 34, a clamping control module 35, and a cutting module 36.

Initially, the traverse control module 32 controls the traverse cylinder 241 to move rightward. After the movement is completed, the synchronous spindle lifting module 33 controls the first cylinder 41 to move upwards so that the sheet of the reverse winder 1 and the synchronous spindle 43 rotate synchronously. Then the lifting cylinder control module 34 drives the lifting cylinder 26 to ascend, and the synchronous rotating shaft lifting module 33 controls the first cylinder 41 to move downwards to the original position when the lifting cylinder is about to ascend to the highest point. Due to the existence of the synchronous rotating shaft 43, the change of the rotating speed of the direct current motor is small when the feeding cutting device 2 clamps. After the lifting cylinder 26 drives the highest point, the clamping control module 35 drives the first clamping device 21 and the second clamping device 22 to clamp and then wind. After the winding is completed, the cutting module 36 drives the cutting mechanism 23 to cut off. After the cutting is completed, the first and

second clamps

21 and 22 are released. Then the lifting cylinder control module 34 controls the lifting cylinder 26 to descend to the home position, and the traverse control module 32 controls the traverse cylinder 241 to move to the left to the home position.

Specifically, there are two second clamping spindles 222. After the first clamping device 21 and the second clamping device 22 ascend and close and clamp the same winding shaft 11, the second clamping rotating shaft 222 clamps the winding shaft 11 and is driven by the winding shaft 11 to rotate synchronously. The second guide bar 223 may guide a position of winding of the sheet. The second guide bar 223 may rotate with the sheet to prevent the sheet from being scratched.

Referring to fig. 4, in an alternative embodiment, the cutting mechanism 23 includes a third guide bar 233 installed on the second fixing frame 221, a cutting rail 231 installed on the second fixing frame 221 and parallel to the third guide bar 233, and a pneumatic cutter 232 moving back and forth along the cutting rail 231.

A cutting rail 231 is fixed to the right side of the third guide bar 223, and the cutting rail 231 is installed in the second fixing frame 221. The pneumatic cutter 232 cuts the lowest sheet of the third lifter 223. When cutting, the sheet is still in a rolling state, and after the pneumatic cutting knife 232 finishes cutting, the cutting opening of the sheet is an inclined opening. Cutting like this, the length that sheet and rolling axle 11 do not contact is shorter, can directly carry out the rolling.
