The film welding, cutting and clamping device 17 is located in the rotating area of ​​the L-shaped cantilever 11; the film compression mechanism 16 is used to compress the film output by the film stretching mechanism 14 in the width direction.

[0028] At the beginning, the stretch film roll is installed on the material rack 15, the stretch film of the stretch film roll passes through the stretch film stretching mechanism 14 and passes through the film compression mechanism 16, the film welding, cutting and clamping device 17 is in a lying state, the coated film roll is placed flat on the working film mechanism, and the free end of the coated film of the coated film roll passes upward through the fixed film clamping mechanism 7 and is clamped; in actual application, the feeding mechanism 9 transports the product 54 to the packaging position, and the rotary drive mechanism 10 drives the L-shaped cantilever 11 to rotate, so that the stretch film stretched by the stretch film stretching mechanism 14 is wrapped around the product 54. In the process of wrapping the stretch film around the product 54 Or before wrapping the stretch film around the product 54, the stretch film lifting drive mechanism 12 drives the lifting seat 13 and the stretch film stretching mechanism 14 to rise and fall to adjust the height of the stretch film wrapped around the product 54; when the product 54 is completely wrapped around the film, the stretch film stretching mechanism 14 drops to a low position, and at this time the stretch film stretching mechanism 14 is located on the side of the product 54 away from the film supply mechanism 6. At this time, the dynamic film clamping mechanism 5 clamps the film, the fixed film clamping mechanism 7 releases the film, and the film lifting drive mechanism 4 drives the dynamic film clamping mechanism 5 to rise, so that the dynamic film clamping mechanism 5 pulls the film, and the film roll on the film supply mechanism 6 rotates to release the film. Put the film, when the film is pulled to the required length, the fixed film clamping mechanism 7 clamps the film, the cutting mechanism 8 cuts the film, and the mobile drive mechanism 2 drives the H-shaped mobile frame 3 to move horizontally, so that the dynamic film clamping mechanism 5 moves horizontally with the film close to the product 54.

After the wrapping film is wrapped, the film compression mechanism 16 first compresses the wrapping film in the width direction, so that the thickness of the wrapping film at the position to be welded becomes thicker, and the welding is more firm. Then, the wrapping film is clamped after being erected by the welding, film cutting and clamping device 17, and then the wrapping film is welded to the covering film around the product 54. Finally, the wrapping film is cut off. The wrapping film clamped by the welding, film cutting and clamping device 17 is convenient for wrapping the next product 54; the feeding mechanism 9 outputs the packaged product 54 and inputs the product 54 to be packaged. The utility model can automatically feed the material and wrap the four sides and the top of the product 54, and compress the wrapping film in the width direction before welding the wrapping film, so that the thickness of the wrapping film at the position to be welded becomes thicker and then welded to the wrapping film wrapped around the product 54, so that the quality of the welded wrapping film is good, the welded interface of the wrapping film is not easy to come off, and the wrapping of the product 54 is more firm and reliable.

[0029] In this embodiment, the film supply mechanism 6 includes a support frame 18 and two sets of support rollers 19 rotatably connected to the bottom of the support frame 18. The two sets of support rollers 19 are used to roll and support the film roll. The fixed film clamping mechanism 7 is mounted on the top of the support frame 18. Specifically, each set of support rollers 19 includes two parallel rollers spaced apart. The film roll is positioned between the two rollers and supported by the two rollers. In actual use, as the dynamic film clamping mechanism 5 pulls the film, the film roll rotates on the two sets of support rollers 19, releasing the film.

[0030] In this embodiment, the fixed film clamping mechanism 7 includes a first fixed film clamping plate 20 mounted on the top of the support frame 18, a fixed film clamping cylinder 21 mounted on the top of the support frame 18, and a second fixed film clamping plate 22 mounted on the piston rod of the fixed film clamping cylinder 21 and arranged opposite to the first fixed film clamping plate 20. The fixed film clamping cylinder 21 is used to drive the second fixed film clamping plate 22 to move closer to or away from the first fixed film clamping plate 20. The first and second fixed film clamping plates 20, 22 are both provided with a plurality of film clamping notches 23, which are used to allow the film clamping end of the dynamic film clamping mechanism 5 to extend into. In actual application, the fixed film clamping cylinder 21 drives the second fixed film clamping plate 22 to move closer to or away from the first fixed film clamping plate 20, so that the first and second fixed film clamping plates 20, 22 clamp or release the film; after the fixed film clamping mechanism 7 clamps the film, it is not only convenient for the cutting mechanism 8 to cut the film, but also helps the dynamic film clamping mechanism 5 to clamp the film.

[0031] In this embodiment, the cutting mechanism 8 includes a film cutting linear drive module 24 mounted on top of the support frame 18 and mounted above the fixed film clamping cylinder 21, and a film cutting knife 25 mounted on the driving end of the film cutting linear drive module 24. The film cutting knife 25 is movably mounted above the first fixed film clamping plate 20. In actual use, the film cutting linear drive module 24 drives the film cutting knife 25 to move horizontally, so that the film cutting knife 25 cuts the film.

[0032] Specifically, a spacing sensor and a height sensor are installed on the side of the dynamic film clamping mechanism 5 near the feeding mechanism 9. Both the mobile drive mechanism 2 and the film lifting drive mechanism 4 are electrically connected to the height sensor. As the dynamic film clamping mechanism 5 pulls the film, the height sensor detects the height to which it rises, ensuring that it pulls the required length of film. As the dynamic film clamping mechanism 5 translates, the spacing sensor detects the distance between it and the product 54, preventing collisions between them.

[0033] In this embodiment, the welding film cutting and clamping device 17 includes a base 26 arranged on one side of the feeding mechanism 9, a welding bottom mold 27 arranged to be lifted and lowered on the base 26, a lifting driver 28 installed on the base 26 and used to drive the welding bottom mold 27 to be lifted and lowered, a swing arm 29 rotatably connected to the base 26 and located on the side of the welding bottom mold 27 away from the feeding mechanism 9, a swing drive mechanism 30 installed on the base 26 and used to drive the swing arm 29 to swing and switch between an upright state and a lying state, a translation driver 31 installed on the swing arm 29, The translation plate 32 is installed on the translation end of the translation driver 31, the hot melt mechanism 33 and the film cutting assembly 34 are installed in parallel on the translation plate 32, and the film clamping module 35 is installed on the base 26 and is located on the side of the film cutting assembly 34 away from the hot melt mechanism 33. The hot melt mechanism 33 is used to cooperate with the welding bottom mold 27, and the translation driver 31 is used to drive the translation plate 32 close to or away from the welding bottom mold 27; specifically, the translation driver 31 can adopt a horizontally arranged cylinder, and the lifting driver 28 can adopt a vertically arranged cylinder.

[0034] At the beginning, the film clamping end of the film clamping module 35 is in an open state, the welding bottom mold 27 drops to a low position, and the swing arm 29 is in a lying state, so that the film clamping end of the film clamping module 35, the welding bottom mold 27, the heat welding mechanism 33 and the film cutting assembly 34 will not interfere with the film wrapping work; when the wrapping film is wrapped around the product 54 for the last few turns, the film compression mechanism 16 compresses the wrapping film output by the wrapping film stretching mechanism 14 in the width direction, and the lifting driver 28 drives the welding bottom mold 27 to rise. As the wrapping film stretching mechanism 14 rotates, the wrapping film with a reduced width is wrapped around the product 54 and the welding bottom mold 27. When the wrapping film is wound, the film clamping end of the film clamping module 35 is closed and clamped. The swing drive mechanism 30 drives the swing arm 29 to swing from the lying state to the standing state, so that the heat welding mechanism 33 and the welding bottom mold 2 7 , the translation driver 31 then drives the translation plate 32, along with the heat-seal mechanism 33 and the film-cutting assembly 34, toward the welding base die 27 , allowing the heat-seal mechanism 33 and the welding base die 27 to cooperate to weld the stretch film. The film-cutting assembly 34 then cuts the stretch film. Finally, the welding base die 27 descends, allowing it to be withdrawn from the welded stretch film. The welded stretch film, under tension, tightly wraps around the product 54. The feeding mechanism 9 then delivers the wrapped product 54 and delivers the new product 54 to the packaging position. At this point, the swing drive mechanism 30 drives the swing arm 29 to swing to a lying position. As the stretch film stretching mechanism 14 wraps the stretch film around the new product 54, the film-clamping end of the film-clamping module 35 opens to release the stretch film, allowing it to continue wrapping around the product 54. During the welding process, the welding base die 27 supports the stretch film, improving the quality of the heat-seal stretch film and the film cutting process.

[0035] In this embodiment, the swing drive mechanism 30 includes a swing drive cylinder 36 and a shaped rotating member 37. The middle portion of the shaped rotating member 37 is rotatably connected to the base 26, and the bottom end of the swing arm 29 is fixedly connected to the top end of the shaped rotating member 37. The main body of the swing drive cylinder 36 is mounted on the base 26, and the piston rod of the swing drive cylinder 36 is hingedly connected to the bottom end of the shaped rotating member 37. The swing drive cylinder 36 is used to drive the shaped rotating member 37 to reciprocate. In actual use, the swing drive cylinder 36 drives the shaped rotating member 37 to reciprocate, and the reciprocating rotation of the shaped rotating member 37 drives the swing arm 29 to swing between the upright position and the lying position.

[0036] In this embodiment, the shaped rotating member 37 comprises a flat plate 38, an inclined plate 39, and a rotating shaft 40. The rotating shaft 40 is located at the junction of the flat plate 38 and the inclined plate 39 and is rotatably connected to the base 26. The swing arm 29 is mounted on the flat plate 38. The driving end of the swing drive cylinder 36 is hinged to the inclined plate 39, and the angle between the flat plate 38 and the inclined plate 39 is acute. This structural design facilitates the swing drive cylinder 36, via the shaped rotating member 37, to drive the swing arm 29 to swing between the upright and lying positions.

[0037] In this embodiment, the hot melt mechanism 33 includes a fixed seat 41, an insulation plate 42, an elastic member 43 and a hot melt joint 44. The fixed seat 41 is installed on the translation plate 32. The insulation plate 42 is elastically connected to the fixed seat 41 via the elastic member 43. The hot melt joint 44 is installed on the insulation plate 42. The insulation plate 42 is provided with an axis rod 45. The fixed seat 41 is provided with a smooth groove 46. The axis rod 45 passes through the smooth groove 46. The axis rod 45 can rotate and move in the smooth groove 46. The hot melt joint 44 is used to cooperate with the welding bottom mold 27. During the process of the hot melt joint 44 contacting and fitting with the welding bottom mold 27, when there is an error in the flatness of the hot melt joint 44, there is an error in the flatness of the welding bottom mold 27, or / and the thickness of the wrapping film is different, since the insulation board 42 is elastically connected to the fixing seat 41 via the elastic member 43, and the shaft 45 can translate or rotate in the smooth groove 46, the hot melt joint 44 can adaptively swing and adjust, so that the hot melt joint 44 can contact and fit with the welding bottom mold 27 flush, so as to ensure the quality of the hot melt wrapping film.

[0038] In this embodiment, the film material compression mechanism 16 includes a lifting drive module 47, a lifting plate 48, and a film pressing wheel 49. The lifting drive module 47 is mounted on the lifting base 13, and the lifting plate 48 is mounted on the lifting end of the lifting drive module 47.

The film pressing wheel 49 is lifted and lowered on the film outlet side of the stretch film stretching mechanism 14, and the axis of the film pressing wheel 49 is arranged to intersect the lifting direction of the film pressing wheel 49. Specifically, the lifting drive module 47 can be an electric screw module, and the axis of the film pressing wheel 49 is perpendicular to the lifting direction of the film pressing wheel 49. When the stretch film needs to be compressed, the lifting drive module 47 drives the lifting plate 48 and the film pressing wheel 49 to descend, causing the film pressing wheel 49 to compress the stretch film in the width direction. Alternatively, the stretch film can be compressed to form a rope, so that the stretch film takes on a rope shape, and the rope-shaped stretch film is used to bundle the wrapped product 54.
