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.

Referring to fig. 1, fig. 2 and fig. 4, in an alternative embodiment, the first clamping device 21 includes a first fixing frame 211, a first clamping rotating shaft 212 disposed on the first fixing frame 211, a lifting cylinder 26 for controlling the first fixing frame 211 to lift, and a first material guiding rod 213 disposed on the first fixing frame 211; the first clamping rotating shaft 212 clamps a take-up reel 11 after the first clamping device 21 and the second clamping device 22 are lifted and gathered.

Specifically, the lifting cylinder 26 starts to clamp after the first fixing frame 211 is lifted to the highest point, and the clamping process can be controlled by the cylinder. After clamping, the first clamping rotating shaft 212 just clings to the winding shaft 11, so that the sheet clings to the winding shaft 11. The first clamping rotary shaft 212 is carried by the take-up shaft 11 to synchronously rotate. There are 1 first clamping rotation shaft 212. The first guide bar 213 is a rotary shaft and can rotate together with the sheet. The first guide bar 213 controls the moving position of the sheet to prevent the sheet from being scratched.

Referring to fig. 1, 2 and 4, the second clamping device 22 includes a second fixing frame 221, a second clamping rotating shaft 222 disposed on the second fixing frame 221, a lifting cylinder 26 for controlling the second fixing frame 221 to lift, and a second material guiding rod 223 disposed on the second fixing frame 221; the second clamping rotating shaft 222 clamps a take-up reel 11 after the first clamping device 21 and the second clamping device 22 are lifted and gathered.

Specifically, the elastic roller tube 111 is made of paper or a hollow tube that can be easily deformed, so that the elastic roller tube 111 continues to rotate after the first and

second clamping devices

21 and 22 are clamped. After winding for several circles, the first clamping device 21 and the second clamping device 22 are loosened, and the winding effect is improved. When the tube 111 is elastically coiled, the installation positions of the first clamping rotating shaft 212 and the second clamping rotating shaft 222 can be controlled by a spring, and the first clamping rotating shaft 212 and the second clamping rotating shaft 222 can radially move away from the center of a circle when the tube is coiled.

Referring to fig. 1 and 2, in an alternative embodiment, the electric control mechanism 3 controls the operations of the turnover winder 1 and the feeding and cutting device 2; the electric control mechanism 3 comprises a counter 31 for counting the winding length, a first proximity switch 32 installed on the turnover winder 1, a second proximity switch 33 installed on the feeding cutting device 2 and in communication connection with the transverse cylinder 241, a third proximity switch 34 installed on the feeding cutting device 2 and in communication connection with the lifting cylinder 26, and a fourth proximity switch 35 installed on the feeding cutting device 2 for controlling the clamping degree.

Specifically, after the first winding is completed, the counter 31 stops counting, the winding shaft 11 stops rotating, and the position of the counter 31 can be adjusted arbitrarily, generally upward, so that the sheet descends obliquely from top to bottom for winding. After the counter 31 stops counting, the reverse winder 1 rotates until the frame for mounting the winding shaft 11 is sensed by the first proximity switch 32 fixed to the reverse winder 1 as shown in fig. 1. As shown in fig. 1, the winding shaft 11 in the horizontal position starts to rotate, the transverse air cylinder 241 starts to extend to the right side until the winding shaft is sensed by the second proximity switch 33, the transverse air cylinder 241 stops extending, and the lifting air cylinder 26 starts to extend until the winding shaft is sensed by the third proximity switch 34. As shown in fig. 2, when the third proximity switch 34 senses a signal, the first clamping device 21 and the second clamping device 22 are closed. The position of the lifting cylinder 26 is controlled by the cylinder to close the first clamping device 21 and the second clamping device 22. After the fourth proximity switch 35 receives the signal, the first clamping device 21 and the second clamping device 22 stop being closed, and the closing degree can be adjusted by adjusting the fourth proximity switch 35 left and right. At this time, the winding shaft 11 at the lower right starts to rotate to continue winding, so that the first clamping rotating shaft 212, the second clamping rotating shaft 222, the first guide bar 223, the second guide bar 223 and the third guide bar 233 synchronously rotate along with the winding shaft 11 at the left side of the turnover machine, and the pneumatic cutting knife 232 moves forwards and backwards to cut off the sheet. The left winding shaft 11 rotates to wind the cut and grown part, and then the first clamping device 21 and the second clamping device 22 are unfolded and reset after being wound for a plurality of circles, and finally the wound part is retracted into the protective box body 24.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the present invention.
