[0002] Heat shrink film is a type of shrink film used in the sale and transportation of various products. Its main functions are to stabilize, cover, and protect the products. Shrink film must have high puncture resistance, good shrinkage, and a certain amount of shrinkage stress. During the shrinkage process, the film must not develop holes. Because shrink film is often used outdoors, UV stabilizers are added. Biodegradable heat shrink film refers to heat shrink film made from biodegradable materials. Mainstream biodegradable materials include PLA, PHA, and PBAT.
[0003] However, during the current film forming and cutting separation process, because the film is cylindrical after overall blow molding and no pressing segmentation component is set during the guiding process, and the cutting position is not effectively pressed, uneven cutting is likely to occur during separation molding, which affects product quality.

[0036] Several lifting electric slide rails 201 are equidistantly embedded at both ends of the inner side of the fixed operating frame 1. One end of the lifting electric slide rail 201 is equipped with a clamping positioning roller 202 through the slide rail seat. The clamping positioning roller 202 is slidably installed on the inner side of the fixed operating frame 1 to realize sliding extrusion processing and ensure steady guidance of the raw material film.
[0037] A guide processing frame 203 is welded to one side of the top of the fixed operating frame 1. Guide electric push rods 204 are installed at both ends of the guide processing frame 203. A guide separation block 205 is snapped into one end of the guide electric push rod 204. The longitudinal section of both the guide separation block 205 and one end of the guide processing frame 203 is circular, so as to achieve steady material separation processing.
[0038] Both ends of the guide frame 203 are equipped with cutting electric push rods 206. One end of the cutting electric push rod 206 is equipped with a cutting blade 207. The cutting blade 207 is placed on the top of the fixed operation frame 1 to achieve steady cutting processing.
[0039] Several bonding electric push rods 208 are equidistantly snapped onto the top of the guide processing frame 203 and the top of the fixed operation frame 1. A bonding processing frame 209 is installed at the bottom of the bonding electric push rod 208. A bonding roller 210 is rotatably connected to the inner side of the bonding processing frame 209.
[0040] To ensure stable operation of the equipment, the input ends of the lifting electric slide rail 201, the guide electric push rod 204, the cutting electric push rod 206, and the bonding electric push rod 208 are all electrically connected to the output end of an external power supply.
[0041] A collection component 3 is provided on the inner side of the fixed operating frame 1;
[0042] The collecting component 3 includes a winding motor 301, a fitting connecting block 302, a winding limit frame 303, a limit electric slide rail 304, and a limit pressing roller 305;
[0043] A winding motor 301 is symmetrically mounted on one end of the fixed operating frame 1 via a motor base, and a fitting connecting block 302 is snapped onto the output shaft of the winding motor 301.
[0044] A winding limit frame 303 is symmetrically and rotatably connected to the side end of the fixed operating frame 1. The sleeve connecting block 302 is sleeved and connected to the winding limit frame 303. The side end of the sleeve connecting block 302 is rotatably attached to one end of the fixed operating frame 1 to achieve steady combination and rotational material taking-up. Several limit electric slide rails 304 are symmetrically and equidistantly installed on the inner side of the fixed operating frame 1. One end of the limit electric slide rail 304 is equipped with a limit pressing roller 305 through the slide rail seat. The limit pressing roller 305 is slidably installed on the inner side of the fixed operating frame 1 to ensure steady pressing and positioning of the film during the material taking-up process.

[0046] The working principle and usage process of this utility model are as follows: When producing heat shrink film, the operator pulls the externally blown cylindrical film to move and enter the clamping and positioning roller 202. At this time, the lifting electric slide rail 201 drives the clamping and positioning roller 202 to gradually squeeze the film material, flatten it, and divide it into two layers. At this time, the guide electric push rod 204 drives the guide separation block 205 to move to both sides. The guide position is adjusted according to the width of the film to guide the separation of the film. The cutting electric push rod 206 drives the cutting blade 207 to move to the cutting position. Through the continuous movement of the material and the contact of the cutting blade 207, continuous cutting is achieved, dividing the material into two layers of film. During the cutting process, the bonding electric push rod 208 drives the bonding processing frame 209 to move, so that the bonding roller 210 contacts the film. The top and bottom ends restrict the positioning, preventing the film from leaving the cutting position while controlling the force on it to ensure the separation speed.
[0047] After the film is cut, it moves along the fixed operating frame 1. The winding limit frame 303 is inserted into the inside of the fixed operating frame 1, so that the winding limit frame 303 engages with the fitting connecting block 302. The winding motor 301 drives the fitting connecting block 302 and the winding limit frame 303 to rotate, placing the film and winding it around the side of the winding limit frame 303. At this time, the limit electric slide rail 304 drives the limit pressing roller 305 to move along the fixed operating frame 1 to press the side of the film, realizing continuous winding and pressing, ensuring the stability of winding, and squeezing out the air between the films to avoid a large number of air bubbles in the wound film roll, which could cause the film to break due to compression.
