[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 As shown, the utility model provides a technical solution: a film laminating device for polyethylene film production, comprising:

[0025] A U-shaped plate 5, a pair of bases 1 are provided at the bottom of the U-shaped plate 5, a conveyor belt 2 is provided between the pair of bases 1, and a polyethylene film roller 11 is provided inside the U-shaped plate 5;

[0026] A plurality of horizontal guide posts 8 for horizontally guiding the polyethylene film are provided inside the U-shaped plate 5. A pair of pressing assemblies 9 are symmetrically provided inside the U-shaped plate 5 and are located between adjacent horizontal guide posts 8 and are used to compress the polyethylene film. A cutting assembly 13 is provided above the horizontal guide posts 8. A driving assembly 12 is provided inside the U-shaped plate 5 for driving the cutting assembly 13 to cut the polyethylene film compressed by the pressing assembly 9.

[0027] The pressing assembly 9 includes a pair of fixed plates 93 symmetrically arranged on the inner walls of opposite sides of the U-shaped plate 5. A pressing electric push rod 92 is vertically arranged on the side of the pair of fixed plates 93 close to the horizontal guide column 8. A pressing plate 91 is arranged between the telescopic axes of the pair of pressing electric push rods 92. The pressing plate 91 is provided with a through slot 911 for the movement of the cutting assembly 13. This design works by the pressing electric push rods 92 in the pair of pressing assemblies 9, driving the pair of pressing plates 91 to move toward or away from each other, thereby completing the pressing of the polyethylene film; then, the driving assembly 12 drives the cutting assembly 13 to move inside the through slot 911 to cut the polyethylene film at the pressing point of the pressing plate 91, thereby preventing the polyethylene film from being torn and deformed, enhancing the cutting effect, and thus improving the laminating effect; wherein, the longitudinal length of the through slot 911 is greater than the length of the product to be laminarized, and the horizontal guide column 8 is rotatably connected to the U-shaped plate 5.

[0028] Reference Figure 1 and Figure 3 A third guide post 10 is provided inside the U-shaped plate 5, located between the polyethylene film roller 11 and the horizontal guide post 8. The third guide post 10 is located above the polyethylene film roller 11. A second guide post 7 is provided inside the U-shaped plate 5, located below the horizontal guide post 8. A first guide post 6 is provided inside the U-shaped plate 5, located below the second guide post 7. This design guides the polyethylene film from the polyethylene film roller 11 to the bottom of the horizontal guide post 8 through the third guide post 10. The polyethylene film is kept horizontal by the second guide post 7, and is then guided to the top of the pressing roller 4 by the first guide post 6. The first guide post 6, the second guide post 7, and the third guide post 10 are respectively rotatably connected to the U-shaped plate 5.

[0029] Reference Figure 1 and Figure 2 The drive assembly 12 includes a conveying cylinder 121 disposed on the upper side of the inner wall of the U-shaped plate 5. An adjustment push rod 122 is provided at the bottom of the slider of the conveying cylinder 121. The cutting assembly 13 is placed below the adjustment push rod 122. This design allows the conveying cylinder 121 in the drive assembly 12 to drive the adjustment push rod 122 to move longitudinally, and the adjustment push rod 122 to drive the cutting assembly 13 to move vertically, thereby achieving height adjustment of the cutting assembly 13 and ensuring that the cutting assembly 13 contacts the polyethylene film to complete subsequent cutting.

[0030] Reference Figure 3 and Figure 4 The cutting assembly 13 includes a knife seat 131 disposed on the telescopic shaft of the electric push rod 122. A cutting head 132 is disposed at the bottom of the knife seat 131. The width of the cutting head 132 is smaller than the width of the through slot 911. This design facilitates the connection of the cutting head 132 through the cutting knife seat 131. The cutting head 132 is connected to the cutting knife seat 131 by bolts.

[0031] Reference Figure 1 A pressing roller 4 is provided above the base 1, and a lifting assembly 3 is provided on the top of the base 1 for driving the pressing roller 4 to move in the vertical direction. This design drives the pressing roller 4 to move in the vertical direction through the lifting assembly 3 to adjust the distance between the pressing roller 4 and the polyethylene film.

[0032] Reference Figure 1 and Figure 2 The lifting assembly 3 includes a guide base 31 disposed on the top of a pair of bases 1. A guide groove 311 is formed on each side of the guide base 31, and a guide block 32 is disposed inside each guide groove 311. A lifting electric push rod 33 connected to the guide block 32 is disposed on the top of the guide base 31. The pressing roller 4 is rotatably disposed between the pair of guide blocks 32. In this design, the lifting electric push rod 33 in the lifting assembly 3 drives the guide block 32 to move vertically along the guide groove 311. The vertical movement of the guide block 32 drives the pressing roller 4 to move vertically.

[0033] Reference Figure 1 The side wall of the U-shaped plate 5 is provided with a drive motor 14 connected to the polyethylene film roller 11. This design drives the polyethylene film roller 11 to rotate and unwind the polyethylene film through the drive motor 14.

[0034] Reference Figures 1-4 As an embodiment of the present utility model: when a product needs to be coated, the staff places the product on the conveyor belt 2, so that the polyethylene film on the polyethylene film roller 11 passes through the third guide column 10, the horizontal guide column 8, the second guide column 7 and the first guide column 6 in sequence, and then contacts the surface of the product. Then, the lifting electric push rod 33 in the lifting assembly 3 is operated to drive the guide block 32 to move in the vertical direction along the guide groove 311. The movement of the guide block 32 drives the pressing roller 4 to move in the vertical direction to contact the polyethylene film on the surface of the product to complete the pressing. Finally, the conveyor belt 2 is operated to drive the product to move, and at the same time, the drive motor 14 is operated to drive the polyethylene film to be unwound, thereby completing the coating operation of the product.

[0035] When the polyethylene film needs to be cut after the lamination is completed, the pressing electric push rods 92 in the pair of pressing assemblies 9 work, driving the pair of pressing plates 91 to move to the side close to each other, completing the pressing of the polyethylene film; then the conveying electric cylinder 121 in the driving assembly 12 works to drive the adjusting electric push rod 122 to move longitudinally, and the adjusting electric push rod 122 moves longitudinally to drive the cutting head 132 on the knife seat 131 to move longitudinally to one side of the polyethylene film, and then the adjusting electric push rod 122 works to drive the cutting head 132 on the knife seat 131 to move vertically to one side of the polyethylene film and enter the interior of the through groove 911, and finally the conveying electric cylinder 121 in the driving assembly 12 works to drive the cutting head 132 to move longitudinally to the other side of the polyethylene film, completing the cutting of the polyethylene film at the pressing position of the pressing plate 91, avoiding the phenomenon of tearing and deformation of the polyethylene film, enhancing the cutting effect, and then improving the laminating effect, thereby improving the practicality of the present utility model.
