The shrink film must have high puncture resistance, good shrinkage and certain shrinkage stress. When the stretch film is produced, the stretched stretch film needs to be wound up by a winder, and then the film roll is removed from the winder. The film roll removed from the winder needs to be placed on an aging rack for two to three days of aging treatment due to the stress caused by stretching.

Then, the film roll is taken out from the inner side of the winding mechanism 7 by the pick-and-place mechanism 3, and at the same time, the pick-and-place mechanism 3 places a new roll 11 on the inner side of the winding mechanism 7, so that the winding mechanism 7 continues to wind the stretch film 10 with the roll 11; S3: Then the transfer mechanism 2 moves the film roll to the side of the aging rack 13 with the film roll, and places the film roll on top of the aging rack 13.

[0047] Working process: when the aging rack 13 is placed, the right end face of the aging rack 13 and the left end face of the gantry 1 are in the same plane. When the stretch film 10 needs to be wound by the reel 11, firstly, the fourth screw transmission assembly 402 is controlled to work through the control cabinet 12, so that the fourth screw transmission assembly 402 lifts the reel 11 upwards through the lifting plate 430, so that the top reel 11 is located at the notch 404, and then the first cylinder 305 is controlled to work through the control cabinet 12, so that the first cylinder 305 moves downward with the clamping block 308 through the connecting seat 306 and the second cylinder 307, until the slider 308 is on both sides of the reel 11 at the notch 404, and then the second cylinder 307 clamps the reel 11 with the clamping block 308, and then under the action of the first cylinder 305, the clamping block 308 takes the reel 11 out of the storage box. 401, during which the reel 11 contacts the adhesive tape 408, and as the reel 11 gradually moves upward, the reel 11 pushes the adhesive tape 408 and the upper roller 407 to the side, causing the upper roller 407 to gradually retract the inner rod 409 back to the inner side of the guide shell 410, and the spring 411 is also compressed until the reel 11 completely passes through the side of the adhesive tape 408. After the reel 11 passes through the side of the adhesive tape 408, the glue attached to the surface of the adhesive tape 408 will be smeared on the surface of the reel 11, and during the reel 11 moving upward from the inner side of the storage box 401, the third motor 413 will rotate clockwise with the adhesive tape 408 through the corresponding roller 407, and when the adhesive tape 408 rotates, the glue will adhere to the surface of the adhesive tape 408 to ensure the uniformity of the smearing. After the clamping block 308 takes the reel 11 out of the inner side of the storage box 401, the second motor 302 rotates 180 degrees counterclockwise with the fixing plate 304 through the rotating shaft 303 (the movement mode of the third motor 302 is to rotate 180 degrees counterclockwise first and then 180 degrees clockwise to prevent the third motor 302 from rotating in one direction all the time and causing the external ventilation pipes connected to the first cylinder 305 and the second cylinder 307 to be entangled), so that the clamping block 308 is at the upper side with the reel 11, and the reel 11 is connected to the second cylinder 307. Under the action of the corresponding first cylinder 305, the clamp block 308 brings the reel 11 between the adjacent first clamping head 704 and the second clamping head 705, and then under the action of the fourth cylinder 701 and the fifth cylinder 706, the first clamping head 704 and the second clamping head 705 are clamped together with the reel 11, and at the same time, the fourth motor 703 rotates the reel 11 counterclockwise by 90 degrees through the first clamping head 704, so that the side of the reel 11 with the glue is under the adsorption plate 503; Then the third cylinder 502 moves the adsorption plate 503 and the stretch film 10 adsorbed on the bottom of the adsorption plate 503 toward the direction close to the reel 11, so that the stretch film 10 is adhered to the reel 11 through the glue, and then the fourth motor 703 automatically winds the stretch film 10 with the reel 11 through the first clamping head 704 until the winding is completed. During the winding process, the stretch film 10 is located at the lower side of the clamping block 308 and the new reel 11 is taken out from the inner side of the storage box 401 in the above manner and waits for use; After the winding is completed, the third cylinder 502 moves downward with the suction plate 503 and fits with the stretch film 10. At the same time, the external air source sucks the stretch film 10 through the air pipe 504 and the suction hole 505. Then the suction plate 503 lifts the stretch film 10 upward, and then the fifth screw transmission assembly 601 separates the stretch film 10 from the film roll with the cutting knife 602. Then, under the interaction of the first cylinder 305 and the second cylinder 307 located on the upper side, the clamping block 308 located on the upper side is pressed against the reel 1 of the film roll. 1 is clamped, and then the second motor 302 rotates 180 degrees clockwise with the fixing plate 304 through the rotating shaft 303, and the new reel 11 and the film roll are exchanged, so that the new reel 11 is re-fixed between the first clamping head 704 and the second clamping head 705, and the new reel 11 rewinds the stretch film 10, and at the same time, the position of the transfer shaft 211 is adjusted under the action of the first screw transmission assembly 202, the second screw transmission assembly 204 and the third screw transmission assembly 205, and The first motor 209 also drives the transfer shaft 211 through the gear 210 and the rack 207 to gradually move the transfer shaft 211 to the right until the transfer shaft 211 is on the side of the film roll drum 11, and then the first motor 209 drives the transfer shaft 211 through the gear 210 and the rack 207 to insert it into the inner side of the film roll drum 11, and then the clamping blocks 308 on both sides of the film roll drum 11 are separated from the drum 11, so that the transfer shaft 211 can support the film roll, and then the first screw transmission assembly 20 2. Under the action of the second screw transmission assembly 204 and the third screw transmission assembly 205, the transfer shaft 211 is placed with the film roll on the aging rack 13, and under the action of the connecting plate 14, the storage box 401 will also move with the moving frame 203. After the film roll is placed on the aging rack 13, the transfer shaft 211 and the storage box 401 are reset and wait for the next use. The above steps are cyclically worked to complete the continuous winding of the stretch film 10 and place the film roll on the aging rack 13.
