The first limiting strip 24 and the second limiting strip 25 are in a rectangular structure, and the right end is in an arc shape. A fixing seat 27 is sleeved outside the hydraulic rod 26. The fixing seat 27 is in a T-shaped structure. A penetrating locking port 28 is opened in the middle of the fixing seat 27. During use, the product is placed on the first conveyor belt 5, and then the first conveyor belt 5 conveys the product from right to left. The first limiting strip 24 in the adjusting device 6 can limit the product to prevent the product from moving out of the first conveyor belt 5. If it is necessary to adjust the position of the product on the first conveyor belt 5, the output ends of the set of hydraulic rods 26 are pushed out, so as to drive the second limiting strip 25 to move towards the first limiting strip 24, and then the product is positioned and limited by the first limiting strip 24 and the second limiting strip 25, so as to operate on products of different sizes.

[0027] As a preferred embodiment of the present invention, a control console 29 is installed at the rear side of the sealing and cutting table 4. The control console 29 is in a rectangular structure. A protective cover 30 is installed outside the control console 29 through a rotating shaft. The protective cover 30 is in an L-shaped structure.

[0028] As a preferred embodiment of the present invention, a first sealing and cutting knife 31 and a second sealing and cutting knife 32 are installed at the driving end of the lifting device 12. The first sealing and cutting knife 31 and the second sealing and cutting knife 32 are in a rectangular structure. After the product and the plastic sealing film 9 enter the second conveyor belt 11 together, the second conveyor belt 11 stops conveying. The first sealing and cutting knife 31 and the second sealing and cutting knife 32 descend with the lifting device 12 to seal the plastic sealing 9 and then cut it off. Then the first sealing and cutting knife 31 and the second sealing and cutting knife 32 rise, and the product wrapped with the plastic sealing film 9 continues to be transported forward. The redundant plastic sealing film 9 is recycled by the recycling conveyor belt 10.

[0029] As a preferred embodiment of the present invention, the ground frame 2 is in a rectangular structure. The top of the ground frame 2 is a through structure. Suction cups 33 and pulleys 34 are installed at the four corners of the bottom of the ground frame 2. The suction cups 33 are in a suction cup shape. A number of storage cabinets 35 are arranged in the ground frame 2 in a horizontally equidistant manner. The suction cups 33 are installed below the built ground frame 2.

The storage cabinets 35 in the ground frame 2 can facilitate the staff to store materials.

[0030] Working principle: During operation, the product is placed on the first conveyor belt 5, and then the first conveyor belt 5 conveys the product from right to left. The first limiting strip 24 in the adjusting device 6 can limit the product to prevent it from moving out of the first conveyor belt 5. If it is necessary to adjust the position of the product on the first conveyor belt 5, the output ends of a group of hydraulic rods 26 push out, driving the second limiting strip 25 to move towards the first limiting strip 24. Then, the product is positioned and limited by the first limiting strip 24 and the second limiting strip 25 to operate on products of different sizes. Then, the plastic film 9 is placed under the film laminating mechanism 7, and one end of the plastic film 9 is passed through the film laminating mechanism 7. Subsequently, the lower film separating plate 19 and the upper film separating plate 20 in the film separating device 8 divide the plastic film 9 into upper and lower layers. The upper layer is below the film separating device 8, and the lower layer is below the first conveyor belt 5 (note that the closed end of the plastic film 9 is on the left and the open end is on the right). The film separating device 8 can adjust the height through the rocker 18 (the rocker 18 drives the lead screw 17 to rotate, and the lead screw 17 can drive the second fixing plate 14 to rise in a threaded manner. A group of connecting columns 15 are for guiding purposes and can also improve the structural stability. In this way, the distance between the lower film separating plate 19 and the upper film separating plate 20 can be adjusted) to meet the height requirements of different products. When the product is conveyed to the left by the conveyor belt, it has entered the plastic film 9. When the bottom of the product contacts the closed end of the plastic film 9, the plastic film 9 will be carried into the next process by the product. After the product and the plastic film 9 enter the second conveyor belt 11, the second conveyor belt 11 stops conveying. The first sealing cutter 31 and the second sealing cutter 32 descend with the lifting device 12 to seal and then cut the plastic film 9. Subsequently, the first sealing cutter 31 and the second sealing cutter 32 rise, and the product wrapped with the plastic film 9 continues to be transported forward. The excess plastic film 9 is recycled by the recycling conveyor belt 10.
