[0064] When the present invention is used, the staff first connects the equipment connecting frame 101 to the film blowing machine through bolts, so that the edge material receiving bucket 104 is aligned with the generation position of the edge material, and the edge material receiving bucket 104 can slowly move downward following the weight of the film edge material. When the four circular limiting rods 503 contact the lower ends of the four arc-shaped limiting holes 1043, there is a certain gap between the two protective baffles 502, and the received film edge material can move through the gap between the two protective baffles 502. Then the staff presses the two rectangular connecting plates 302 inward, and then puts the film edge material collecting bag on the bottom end of the edge material receiving bucket 104, and then loosens the two rectangular connecting plates 302, which is convenient for the staff to fix the film edge material collecting bag through the two rows of collection bag positioning rods 301, ensuring the edge material receiving The bottom of the collecting bucket 104 is always inserted into the film edge material collecting bag, which reduces the labor intensity of the staff; the setting of a row of supporting springs B303 prevents the two rows of collecting bag positioning rods 301 from falling off from the film edge material collecting bag, so that the two rows of collecting bag positioning rods 301 can move only after being subjected to force, thereby improving the positioning effect of the film edge material collecting bag; when the film edge material in the edge material receiving bucket 104 reaches the preset receiving weight, the equipment connecting frame 101 can automatically press the control button A203; when the control button A203 is in a pressed state, the control panel 201 controls the output shafts of the four linear electric cylinders A601 to fully retract; when the output shafts of the four linear electric cylinders A601 are fully retracted, the four circular sealing rods 603 push the two protective baffles The angle of 502 changes, so that the inner sides of the two protective baffles 502 contact each other. When the four circular limiting rods 503 contact the upper ends of the four arc-shaped limiting holes 1043, the inner sides of the two protective baffles 502 contact each other, so as to prevent splashing of the film edge materials when they are broken; at the same time, the four circular positioning rods 604 are inserted into the four positioning circular holes 1011 and the four positioning grooves 1041, which play a positioning role for the edge material receiving bucket 104, so that the edge material receiving bucket 104 is more stable during subsequent crushing; when the output shafts of the four linear electric cylinders A601 are all retracted, the multi-functional frame 602 on the front side can automatically press the control button B204; when the control button B204 is in a pressed state, the control panel 201 controls the servo motor 402 to work, so as to realize the film edge Automatic crushing of film scraps; the setting of two connecting gears 403 enables the two scrap recovery rollers 401 to rotate inward at the same time, thereby improving the crushing efficiency of the film scraps; when the control button B204 is in a pressed state, the control panel 201 controls the four linear electric cylinders B701 to work, so that the scrap support plate 702 is intermittently separated from the bottom of the film scrap collection bag. When the scrap support plate 702 and the film scrap collection bag are in a separated state, the film scraps can automatically tighten the bottom of the film scrap collection bag under the action of gravity, thereby avoiding wrinkles at the bottom of the film scrap collection bag and improving the utilization effect of the film scrap collection bag; when the film scraps in the scrap receiving bucket 104 are discharged, the scrap receiving bucket 104 automatically resets upward under the action of six supporting springs A105.
