Specifically, the control switch 83 is turned on, and the overall controller 82 controls the film supply module 20 to start operating. The film supply module 20 transfers the film material.

In the second step, the film-drawing bag-making module 30 cuts and seals the film material under the control of the control module 80 to make a film bag with an opening on one side.

Specifically, the general controller 82 controls the film pulling assembly 31 to pull the film material to the film clamping assembly 32, then controls the film clamping assembly 32 to clamp the film material and pull the film material to the preset position, and meanwhile, the film pulling assembly 31 returns to the initial position. The film is then compressed and fixed by the bag platform 331 and the bag knife assembly 332 of the bag making assembly 33, and the bag making knife 336 heat-cuts and seals the film to produce a film bag with an opening on one side. The openings of the film bags face the feed module 10 and the push-in bag module 40.

And step three, when the film supplying module 20 feeds the film, the material to be coated is fed to the bag feeding station by the feeding module 10.

Specifically, the feeding assembly 11 feeds the material to be coated into the coating machine 100, and then the lifting assembly 12 lifts the material to be coated to reach the bagging station.

Step four, after the film bag making module 30 completes the making of the film bag, the control module 80 controls the bag opening assembly 42 of the bag entering module 40 to open the film bag, and then the material pushing assembly 43 pushes the material to be coated into the bag from the opening of the film bag.

Specifically, after the film clamping assembly 32 clamps the film material and the film drawing rod 311 retracts to the initial position, the bag opening sheet 422 of the bag opening assembly 42 is inserted into the two-layer film material, then the film bag clamping assembly 421 clamps the upper and lower layer film materials, and after the bag making assembly 33 completes heat sealing and cutting of the film material, the bag opening lifting motor 4241 of the bag opening assembly 42 controls the second bag opening rod 4232 to move away from the first bag opening rod 4231, so that the bag opening sheet 422 opens the film bag. Then, the pushing driving device 434 of the pushing assembly 43 is activated, and the pushing rod 432 pushes the material to be coated on the lifting assembly 12 forward, and the material passes through between the first bag opening rod 4231 and the second bag opening rod 4232 and enters into the film bag. The bag holding assembly 421 then releases the bag and the pusher rod 432 continues to push the bag material forward to the bag sealing module 50.

Step five, the control module 80 controls the bag sealing module 50 to seal the opening of the film bag and cut off the excess material of the opening, and simultaneously the excess material cutting module 60 cuts off other excess materials of the packaging material.

Specifically, when the material loaded into the film bag is pushed to the bag sealing module 50, the side of the packaging material opposite to the opening of the film bag abuts against the two positioning blocks 621 of the residue removing module 60. The upper bag-sealing unit 51 and the lower bag-sealing unit 52 of the bag-sealing module 50 perform heat cutting and sealing of the film bag opening, and the residue-cutting unit 62 of the residue-cutting module 60 cuts off the residue of the packaging material on one side.

After the leftover materials of the edges and corners of one side of the packaging materials are cut off, the control module 80 controls the transferring component 61 to place the materials into the cutting station, the other side of the materials with the leftover materials is abutted against the third positioning block 6213 and the fourth positioning block 6214, then the leftover materials are cut off by the leftover material cutting component 62, and the transferring component 61 sends the materials to the product output module 70. Product output module 70 conveys the packaged material out of encapsulation tool 100.

And step six, feeding the material subjected to film coating into a thermal shrinkage furnace, and enabling the film material on the material to be further tightly attached to the material through thermal shrinkage.

It will be appreciated that the bag opening sheet 422 of the bag opening assembly 42 may extend between the two

film sheets

91, 92 after the film is pulled by the stretch film bag making module 30 and before the bag making assembly reaches the film.

Referring to fig. 16 and 17, which are schematic views of another embodiment of the bag inlet platform 44, the size of the bag inlet platform 44 can be adjusted to accommodate different sizes of materials, and the bag inlet platform comprises a base 441, a bag inlet base 442, a connecting belt 443, elastic devices 444 of the connecting belt disposed on two sides of the connecting belt, and an adjusting member 445 of the bag inlet base. The bag inlet base 442 is provided on the top of the base 441, and bag inlet guide plates 4421 are provided on both sides thereof. The width between the bag-in guide plates 4421 can be adjusted according to the width of the packaged materials. The tape 443 has one end connected to the bag inlet abutment 442 and the other end offset from the direction of material movement (i.e., from the plane of the bag inlet abutment 442) and secured to a fastener strip 446. The belt elastic device 444 includes a guiding post 4441 and an elastic member 4442 sleeved on the guiding post 4441, which is a spring in the present embodiment, for maintaining the tension of the belt 443. Through holes 4461 are formed at both ends of the fixing bar 446, so that one end of the guiding column 4441 can pass through the through hole 4461 and be fixed on a fixing seat 447. The other end of the guide 4441 is fixed to a support 448.

The inlet base adjusting member 445 is provided on the base 441 and is connected to the inlet base 442, and the position of the inlet base 442 can be adjusted in the direction in which the material to be packaged is pushed. When the length of the material to be packaged is greater than the length of the bag inlet base 442, the bag inlet base platform adjusting member 445 drives the bag inlet base 442 to move along the material pushing direction. At this time, the connecting belt 443 is pulled, the fixing strip 446 moves along with the connecting belt 443 and compresses the elastic member 4442, and the portion of the connecting belt 443, which is close to the bag inlet base 442, is pulled into the material pushing direction to make up for the shortage of the length of the bag inlet base 442, so that the size of the bag inlet platform 44 is adjustable, and the package material is prevented from falling off in the material pushing process.

In the present embodiment, the connecting belt 443 is disposed in a substantially Z-shape, and rollers are disposed at positions where the extending direction of the connecting belt 443 is changed, that is, at corner positions, to maintain the tension of the connecting belt 443.
