[0063] Specific usage method and function of this embodiment:

[0064] When the present invention is in use, first, the operator connects the equipment connecting frame 101 to the blown film machine through bolts, aligns the edge material receiving hopper 104 with the position where the edge material is generated. The edge material receiving hopper 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. The received film edge material can move through the gap between the two protective baffles 502. Then, the operator presses the two rectangular connecting plates 302 inward, puts the film edge material collection bag on the bottom end of the edge material receiving hopper 104, and then releases the two rectangular connecting plates 302, which facilitates the operator to fix the film edge material collection bag through the two rows of collection bag positioning rods 301, ensuring that the bottom of the edge material receiving hopper 104 is always inserted into the film edge material collection bag, reducing the labor intensity of the operator; the arrangement of a row of support springs B303 prevents the two rows of collection bag positioning rods 301 from detaching from the film edge material collection bag, making the two rows of collection bag positioning rods 301 able to move only when force is applied, improving the positioning effect of the film edge material collection bag; when the film edge material in the edge material receiving hopper 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 the pressed state, the control panel 201 controls the output shafts of the four linear cylinders A601 to all contract; when the output shafts of the four linear cylinders A601 all contract, the four circular sealing rods 603 push the two protective baffles 502 to change their angles, making the inner sides of the two protective baffles 502 contact. 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, preventing the film edge material from splashing when it breaks; at the same time, the four circular positioning rods 604 are inserted into the four positioning round holes 1011 and the four positioning grooves 1041, playing a positioning role for the edge material receiving hopper 104, making the edge material receiving hopper 104 more stable during subsequent crushing; when the output shafts of the four linear cylinders A601 all contract, the front multi-functional frame 602 can automatically press the control button B204; when the control button B204 is in the pressed state, the control panel 201 controls the servo motor 402 to work, realizing the automatic crushing of the film edge material; the arrangement of the two connecting gears 403 enables the two edge material recycling rollers 401 to rotate inward simultaneously, improving the crushing efficiency of the film edge material; when the control button B204 is in the pressed state, the control panel 201 controls the four linear cylinders B701 to work, making the edge material support plate 702 intermittently separate from the bottom of the film edge material collection bag. When the edge material support plate 702 is in the separated state from the film edge material collection bag, the film edge material can automatically tighten the bottom of the film edge material collection bag under the action of gravity, preventing wrinkles at the bottom of the film edge material collection bag and improving the utilization effect of the film edge material collection bag; when the film edge material in the edge material receiving hopper 104 is discharged, the edge material receiving hopper 104 automatically resets upward under the action of the six support springs A105.
