[0001] The utility model relates to the technical field of PE film cutting, in particular to a PE film cutting device. Background Art

[0002] PE protective film is the simplest macromolecular organic compound and the most widely used polymer material in the world today. PE protective film uses a special polyethylene (PE) plastic film as its base material and is categorized by density into high-density polyethylene protective film, medium-density polyethylene, and low-density polyethylene. The greatest advantage of PE protective film is that it protects the protected product from contamination, corrosion, and scratches during production, processing, transportation, storage, and use, preserving the original smooth and glossy surface, thereby improving product quality and market competitiveness.

[0003] During the production process of PE film, it is usually necessary to cut the PE film into specified sizes for practical application and to meet different usage requirements. Since the PE film is relatively thin, the film is prone to wrinkles and unevenness during the cutting process, and is also prone to deviation. The stability of the film during the cutting process needs to be improved. Utility Model Content

[0025] See also Figure 1-6 The utility model provides a technical solution: a PE film cutting device, comprising a substrate 1, on which a film cutting assembly 2, a first pressing roller assembly 3 and a second pressing roller assembly 4 are arranged, the first pressing roller assembly 3 and the second pressing roller assembly 4 are respectively located on both sides of the film cutting assembly 2, the film cutting assembly 2 comprises a stand 21 and a film cutting roller 22, the film cutting roller 22 is provided with multiple groups of cutting bases 23, the lower end of the cutting base 23 is provided with a blade 24, the first pressing roller assembly 3 comprises a group of first intermediate pressing rollers 31 and two groups of first side pressing rollers 32, the second pressing roller assembly 4 comprises a group of second intermediate pressing rollers 41 and two groups of second side pressing rollers 42.

[0026] like Figure 4 As shown, the PE film passes through the first pressing roller assembly 3, the film cutting assembly 2 and the second pressing roller assembly 4 in sequence, and a cutting position is formed between the blade 24 of the film cutting assembly 2 and the substrate 1. The PE film passes through the cutting position during the movement and contacts the blade 24. Under the action of the blade 24, the film is cut and the whole PE film is cut into multiple groups of film materials of uniform size to achieve film cutting. The cutting size of the PE film is controlled by the spacing between the blades 24 at adjacent positions.

[0027] like Figure 4 and Figure 5 As shown, a group of pressing grooves 5 are formed between the first pressing roller assembly 3 and the substrate 1, and a group of pressing grooves 5 are formed between the second pressing roller assembly 4 and the substrate 1. The two groups of pressing grooves 5 are respectively located on both sides of the cutting position. When the PE film is cut, the first pressing roller assembly 3 and the second pressing roller assembly 4 are used to limit and stabilize the two ends of the film to be cut, thereby improving the stability and flatness of the PE film during the cutting process, and the PE film is not prone to deviation and wrinkling, thereby improving the film cutting quality.

[0028] The two groups of first side pressing rollers 32 are respectively located on both sides of the first middle pressing roller 31 .

[0029] A pressing groove 5 is formed between the first intermediate pressing roller 31 , the first side pressing roller 32 and the substrate 1 .

[0030] like Figure 4 As shown, the two groups of first side pressure rollers 32 guide the film body so that the film body can enter and exit the first pressure roller assembly 3 along the specified direction. The first intermediate pressure roller 31 presses the film body into the pressure groove 5 to limit and guide the film body, thereby improving the stability of the film body during the film cutting process.

[0031] The two groups of second side pressing rollers 42 are respectively located on both sides of the second middle pressing roller 41 .

[0032] A pressing groove 5 is formed between the second middle pressing roller 41 , the second side pressing roller 42 and the substrate 1 .

[0033] like Figure 4 As shown, the two sets of second side pressure rollers 42 guide the film body so that the film body can enter and exit the second pressure roller assembly 4 along the specified direction. The second intermediate pressure roller 41 presses the film body into the pressure groove 5 to limit and guide the film body, thereby improving the stability of the film body during the film cutting process.

[0034] A through hole 27 is formed on the cutting base 23 , and the film cutting roller 22 passes through the through hole 27 of the cutting base 23 and is slidably connected to the cutting base 23 .

[0035] A screw hole 28 is provided on the top of the cutting base 23 , and the film cutting roller 22 and the cutting base 23 are fixed by a first locking bolt 25 .

[0036] Loosen the first locking bolt 25 to release the fastening force between the cutting base 23 and the film cutting roller 22. At this time, the cutting base 23 can slide along the film cutting roller 22 to adjust the position of the cutting base 23, that is, adjust the position of the blade 24. After the position adjustment of the blade 24 is completed, tighten the first locking bolt 25 and re-tighten the cutting base 23 and the film cutting roller 22.

[0037] The cutting base 23 is easy to install and remove and adjust its position. The position of the blade 24 at the lower end of each cutting base 23 can be quickly adjusted according to the film cutting requirements, thereby improving the flexibility of use.

[0038] Among them, there are two groups of vertical frames 21, and the two groups of vertical frames 21 are respectively located on both sides of the upper end of the substrate 1. The two ends of the film cutting roller 22 pass through the two groups of vertical frames 21 respectively. The vertical frames 21 and the film cutting roller 22 are fixed by the third locking bolt 29. The vertical frames 21 and the film cutting roller 22 are detachably connected, which facilitates the assembly and disassembly of the film cutting roller 22.

[0039] Among them, the cutting base 23 and the blade 24 are fixed by a second locking bolt 26. The cutting base 23 and the blade 24 are detachably connected, which makes it convenient to assemble and disassemble the blade 24. When the blade 24 is partially damaged, the blade 24 at the designated position can be replaced, which is conducive to maintenance.

[0040] Working principle: When in use, adjust the position of the blade 24 at the lower end of each cutting base 23 according to the film cutting requirements, such as Figure 4 As shown, the PE film passes through the first pressing roller assembly 3, the film cutting assembly 2 and the second pressing roller assembly 4 in sequence, and a cutting position is formed between the blade 24 of the film cutting assembly 2 and the substrate 1. The PE film passes through the cutting position during the movement and contacts the blade 24. Under the action of the blade 24, the film is cut, and the whole PE film is cut into multiple groups of film materials of uniform size. To achieve film cutting, the two groups of first side pressing rollers 32 of the first pressing roller assembly 3 guide the film body so that the film body can enter and exit the first pressing roller assembly 3 along the specified direction, and the first middle pressing roller 31 presses the film body into the pressing groove 5. The two groups of second side pressing rollers 42 of the second pressing roller assembly 4 guide the film body so that the film body can enter and exit the second pressing roller assembly 4 along the specified direction, and the second middle pressing roller 41 presses the film body into the pressing groove 5. When cutting the PE film, the two ends of the film to be cut are limited and stabilized by the first pressing roller assembly 3 and the second pressing roller assembly 4, thereby improving the stability and flatness of the PE film during the film cutting process.
