All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figures 1-5 shown, the present invention provides an efficient automatic L-shaped film sleeving and sealing machine, which includes a workbench 10, a film sleeving mechanism, a sealing mechanism 40, and a film cutting mechanism 50. A transmission mechanism 11 for product transmission is provided on the workbench 10. A cleaning assembly 20 for product cleaning is provided on the transmission mechanism 11. The film sleeving mechanism includes a film unwinding assembly 30 and an unfolding member 31. The film unwinding assembly 30 is provided on the workbench 10 and is located on one side of the input end of the transmission mechanism 11 for the transmission and supply of the shrink film. The unfolding member 31 is provided on the input end of the transmission mechanism 11 and is located on one side of the film unwinding assembly 30 for unfolding the two-layer folded shrink film. The sealing mechanism 40 is provided on the workbench 10 and is located on one side of the middle of the transmission mechanism 11. A heating knife 41 is provided inside the sealing mechanism 40. The heating knife 41 is provided on one side of the transmission mechanism 11 for sealing the shrink film. The film cutting mechanism 50 is provided on the workbench 10 and is located at the output end of the transmission mechanism 11 for cutting the shrink film between two products.

[0026] The film unwinding mechanism mainly consists of a film unwinding roller and an adjusting roller. A driving motor for driving the film unwinding roller is provided below the film unwinding roller. The adjusting roller is located in front of the film unwinding roller. There are multiple groups of adjusting rollers, which are reasonably distributed according to the required tension of the shrink film to ensure the flatness of the shrink film.

[0027] By setting the cleaning assembly 20, the film sleeving mechanism, the sealing mechanism 40, and the film cutting mechanism 50, the staff places the product on the transmission mechanism 11 and transports the product through the transmission mechanism 11. The dust on the surface of the product is cleaned by the cleaning assembly 20. Then, the shrink film is supplied through the film unwinding assembly 30 and the two-layer folded shrink film is unfolded by the unfolding member 31. During the transportation process, the product is preliminarily wrapped by the shrink film. After wrapping, it is transported to the sealing mechanism 40, and the opening of the shrink film is heated and sealed by the heating knife. Then, the shrink film between two products is heat-sealed and cut by the film cutting mechanism 50, thereby realizing the automatic packaging of the product and improving the packaging efficiency and production quality of the packaging.

[0028] Further, the cleaning assembly 20 includes a position sensor 21 and a cleaning bracket 22. The position sensor 21 and the cleaning bracket 22 are arranged front and back at the input end of the transmission mechanism 11. The position sensor 21 is a grating sensor for detecting whether the product is transported to the location where the cleaning assembly 20 is located. The cleaning bracket 22 is provided with cylinders 23 and jet plates 24 distributed left and right. The output end of the cylinder 23 is connected to one end of the jet plate 24. A plurality of groups of jet nozzles 25 are arranged at equal intervals at the bottom end of the jet plate 24, and one end of the jet nozzle 25 passes through the top end of the cleaning bracket 22. A baffle for preventing dust diffusion is arranged on one side of the cleaning bracket 22 close to the unfolding member 31, and the baffle is made of a soft material. When the position sensor 21 detects the product, the cylinder 23 is activated and transmits gas into the jet plate 24, and the surface of the product is jet-blown through a plurality of groups of jet nozzles 25 to blow away the dust on the product, avoiding the influence of dust on the packaging of the product. Moreover, by arranging the baffle, the dust is prevented from blowing into the unfolding member 31, improving the packaging effect of the product.

[0029] Further, a first lifting assembly is arranged between the unfolding member 31 and the workbench 10. The first lifting assembly includes a guide frame 312 and a first lifting driving member 311.

The first lifting driving member 311 is arranged at the top end of the guide frame 312, and the output end of the first lifting driving member 311 is connected to the first fixing plate 313. When the first lifting driving member 311 is started, the first lifting driving member 311 drives the first screw rod 45 to rotate, and the first screw rod 45 drives the first fixing plate 313 to move up or down, thereby adjusting the height of the unfolding member 31 to adapt to products of different heights.

[0030] Furthermore, the film sleeving mechanism further includes a guiding assembly. The guiding assembly includes a guiding plate 32. The guiding plate 32 is connected to the transmission mechanism 11 through a movable frame. The movable frame is rotatably connected to the transmission mechanism 11. By arranging the guiding plate 32, the product is guided so that the product can accurately enter into the shrink film, thereby completing the preliminary wrapping of the product.

[0031] Further, the sealing mechanism 40 includes a sealing bracket 42 and a second fixing plate 43. The sealing bracket 42 is arranged on one side of the middle part of the transmission mechanism 11. A first runner 44 is provided at the top of the sealing bracket 42. The first runner 44 and the second fixing plate 43 are connected by a first screw rod 45. On the side of the second fixing plate 43 close to the transmission mechanism 11, there are two sets of transmission belts 47 distributed up and down and two sets of guide wheels 46 distributed up and down. The guide wheels 46 are located on the input side of the transmission belts 47. The bottom end of the heating knife 41 has a V-shaped opening 411, and the V-shaped opening 411 is located between the two sets of transmission belts 47. The shrink film after wrapping the product is transmitted by the guide wheels 46 and the transmission belts 47, and the opening of the shrink film is heat-sealed through the V-shaped opening 411 of the heating knife 41, thereby realizing the sealing of the shrink film, improving the sealing efficiency of the shrink film, and also adjusting the height of the second fixing plate 43 through the first runner 44 and the first screw rod 45, so that the positions of the guide wheels 46 and the transmission belts 47 can be adapted to products of different heights.

[0032] Furthermore, a second lifting driving member 48 is arranged between the heating knife 41 and the second fixing plate 43, and the second lifting driving member 48 is a cylinder 23. The lifting driving member is located on the side of the second fixing plate 43 away from the transmission belt 47. By setting the second lifting driving member 48, the height of the heating knife 41 is adjusted to be adapted to products of different heights.

[0033] Further, the film cutting mechanism 50 includes a film cutting bracket 51, a third fixing plate 52 and a sealing knife seat 54. The film cutting bracket 51 straddles the output end of the transmission mechanism 11. A second runner 55 is provided at the top of the film cutting bracket 51.

A cutting knife 58 is provided at the bottom end of the third fixing plate 52, and the cutting knife 58 is connected to the output end of the third lifting driving member 57. A heating member 59 is provided on the third fixing plate 52. The heating member 59 is arranged on one side of the cutting knife 58 and abuts against the cutting knife 58. The sealing knife seat 54 is arranged in the transmission mechanism 11 and is located below the cutting knife 58. After the shrink film is sealed, the third lifting driving member 57 is started, and the third lifting driving member 57 drives the cutting knife 58 to move downwards and abut against the sealing knife seat 54, thereby heat-sealing and cutting the shrink film between the two products, and further completing the cutting on both sides of the shrink film. The height of the third fixing plate 52 is also adjusted through the second runner 55 and the second screw rod 56, so that the position of the cutting knife 58 can be adapted to products of different heights.

[0034] Furthermore, limiting shafts 581 are respectively arranged at both ends of the cutting knife 58. Buffer blocks corresponding to the limiting shafts 581 are arranged on the sealing knife seat 54. By setting the limiting shafts 581 and the buffer blocks, it is avoided that the cutting knife 58 exceeds the stroke during cutting, and the service life of the cutting knife 58 is improved.
