Driving the pushing cylinder 105 causes the pushing plate 106 to push the drum 12 inside the limiting shell 104 to the conveyor 103 for transport.

[0020] As attached Figure 3 As shown in the above embodiment, specifically, the lifting and disassembly seat structure 11 includes a lifting seat 111, with a second electric slide 112 bolted to the rear side inside the lifting seat 111; a stabilizing seat 113 is inserted inside the lifting seat 111, and the rear side of the stabilizing seat 113 is bolted to the sliding element of the second electric slide 112; a supporting square column 116 and a transmission rack 117 are inserted inside the stabilizing seat 113, and the upper side inside the supporting square column 116 is bolted to the transmission rack 117; conveying gears 114 are respectively shafted to the left and right sides inside the stabilizing seat 113; a conveying motor 115 is bolted to the left and right sides of the front end of the stabilizing seat 113, and the output shaft of the conveying motor 115 is embedded in the conveying gear 114; driving the conveying motor 115 causes the conveying gear 114 to rotate, thereby driving the supporting square column 116 to be inserted into the drum 12 under the cooperation of the transmission rack 117.

[0021] In the above embodiment, specifically, the right side of the surface of the stabilizing platform 101 is bolted with a support base 1.

[0022] In the above embodiment, specifically, the middle part of the stabilizing platform 101 is provided with a groove, and the limit switch 102 installed inside it corresponds to the drum 12.

[0023] In the above embodiment, specifically, a through hole is provided at the rear of the lower part of the limiting shell 104, which corresponds to the push plate 106. A rubber strip is glued to the upper part of the inner wall of the through hole at the lower part of the limiting shell 104 to restrict the placed roller 12 and prevent it from rolling out easily.

[0027] Working principle

[0028] The working principle of this utility model is as follows: During the film material winding process of the blown film machine, when changing rolls, the pusher cylinder 105 is driven to push the pusher plate 106 to push the roll 12 inside the limiting shell 104 to the conveyor 103 for conveying. After contacting the limit switch 102, the conveyor motor 115 is driven to rotate the conveyor gear 114, which, with the cooperation of the transmission rack 117, drives the support column 116 to insert into the roll 12. Then, the second electric slide 112 is driven to cooperate with the stabilizing seat 113 to drive the roll 12 to rise to the T-shaped platform 2 between the clamping seats 4. Finally, the first electric slide 3 is driven to clamp and fix the clamping seat 4. Then, the film material is pulled to the roll 12. At the same time, the winding motor 8 is driven to rotate with the cooperation of the gearbox 7, the transmission gear 6 and the T-shaped platform 2 to perform the winding work. After the winding is completed, the clamping seat 4 is released and the second electric slide 112 is driven to descend. Then, the support column 116 is moved to the left to separate from the material, so that the material can be pushed to roll on the stabilizing platform 101 for transportation.
