[0046] Working principle:

[0047] The working principle of the film feeding and collecting mechanism 1 is as follows: the incoming film (single-layer heat shrinkable film, generally PE material) is manually loaded, the position is adjusted in the center, and it is placed on the film rack. The upper end of the film feeding component 11 is wrapped around the film collecting component 12, and the film clamping and pricking roller 115 is clamped; when the film is wrapped, the clamping box conveying mechanism 2 drives the product to drag backward, and the film will be dragged and driven by the product. At this time, the film feeding and collecting motors 122 are stopped, and the gravity roller 116 is pulled up and leaves the film position sensor. The film feeding motor 114 starts to put the film to supplement the film position until the film position sensor receives a signal; when the hot cutting is over (hot cutting will not cause the film to break), the film feeding motor 114 stops, and the film collecting motor 122 rotates to drag the waste material with the joint downward to prepare a new film for the second product, and the gravity roller 116 is brought to a fixed position, and the film collecting motor 122 stops; the film feeding motor 114 continues to feed the material to the film position sensor to obtain a signal.

[0048] The working principle of the box clamping and transporting mechanism 2 is as follows: the packaging box (within the appropriate size range) is manually placed onto the conveyor belt 212, and the conveyor belt 212 has corresponding sensors and stoppers to position and separate the square boxes; the box clamping and transporting mechanism 2 clamps the front square box from both ends, and the servo motor 233 drives the square box to move to the next position (while the second square box is moved into place and positioned again); during the dragging of the square box, the film will be wrapped around the square box; when the top of the square box is pressed tightly, the film clamping jaw assembly 23 returns to the second square box, ready to clamp its two square boxes.

[0049] Working principle of the transverse sealing and hot cutting mechanism 3: After the square box is wrapped with film, the transverse sealing pressure plate assembly 32 (with heat insulation material) falls from above to press the two layers of film, and the bottom transverse sealing cutter assembly 31 rises to seal and cut the film, wrapping the square box like a cuff; after hot cutting, the incoming film is also welded to form a new film surface, and the bottom film collecting assembly 12 rolls down the section with the weld; the square box after transverse sealing is like a wrapped candy, with extra film tubes at both ends, which are used as end sealing materials by the subsequent workstations.

[0050] Working principle of film cutting mechanism 4: After the square box is wrapped and sealed horizontally, it is brought to the next station by the unloading belt and stopped for positioning; the side seal upper plate assembly 41 is pressed down to press the square box, and at the same time, the side seal cutter assembly 42 rises, and the upper and lower end film cutting mechanisms 4 are in place; the synchronous lever mechanism 417 (closed state) of the side seal upper plate assembly 41 presses down the excess film at both ends of the square box. The side film handling mechanism 421 is opened by vacuum; the side seal upper plate assembly 41 is folded, and the lever mechanism 417 is opened to move the lever to the edges of the four corners of the square box and position it. The side film-sorting mechanism 421 is quickly pulled open to both ends to straighten the film tubes at both ends; the side cutters 423 (hot cutters) on both sides clamp and cut off and seal the four sides of the film; the bottom cutter 424 (hot cutter) cuts and seals the bottom side of the film from bottom to top, and the vacuum cleaner sucks away the cut waste film; from then on, all film cutting is completed, and the conveyor belt 212 brings the product into the heat shrink machine for heat shrinkage, and the product is completed.

[0051] The overall operation sequence is: manually loading the film, placing the square boxes on the conveyor belt 212 one by one; the box clamping and transporting mechanism 2 moves the square boxes to the transverse sealing and hot cutting mechanism 3, wraps the film and seals it transversely; the conveyor belt 212 moves, driving the square boxes to the film cutting mechanism 4, and seals the two ends along the bottom edge; the conveyor belt 212 brings the product off the line and sends it to the heat shrink machine for heat shrinking; the finished product comes out.

[0052] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present invention and fall within the protection scope of the present invention.
