Description

Technical Field

[0001] This utility model belongs to the field of film lamination technology, specifically relating to a PE film flat lamination device. Background Technology

[0002] PE film, or polyethylene film, is a film material made from polyethylene resin as the main raw material through processes such as blow molding and casting. It is widely used in packaging, agriculture, industry and other fields.

[0003] Chinese patent CN221954655U provides a PE film flattening and laminating device, including a flattening and laminating device body. A fixed base is fixedly connected to the upper end face of the flattening and laminating device body, and a threaded roller is rotatably connected inside the fixed base. The outer surface of the threaded roller has two threaded grooves with opposite directions. A first mounting seat is installed on the upper end face of the flattening and laminating device body. This invention uses the threaded grooves with opposite directions engraved at the midpoint of the threaded roller. When the film contacts the inclined threaded grooves on the surface of the threaded roller during film lamination, the friction will give the film a lateral expansion force, which will stretch the film to the left and right ends, thereby reducing wrinkles during film lamination and improving production yield and efficiency. At the same time, the two pressure rollers can evenly and smoothly attach the flattened film to another film, improving the lamination effect of the PE film flattening and laminating device and reducing production costs.

[0004] However, in the above-mentioned technologies, during the processing of PE film, PE material debris and particles may remain on the equipment, which will reduce the efficiency of the next work and affect the service life of the equipment. Utility Model Content

[0027] Example 1:

[0028] like Figure 1-5 As shown, this utility model provides a PE film flattening and laminating device, including a main body 2, a threaded roller 3 and a winding roller 13 respectively installed at both ends of the main body 2, and a pressure plate 10 installed in the middle of the main body 2. It also includes a brush roller 4 and a high-pressure pipe 5. The two ends of the brush roller 4 are respectively connected to the two ends of the threaded roller 3 and are located obliquely above the threaded roller 3. The lowest position of the brush roller 4 is higher than the film entry path to avoid affecting the PE film processing.

[0029] In this embodiment, the high-pressure pipe 5 is installed above the brush roller 4, and uses high-pressure airflow to blow away stubborn impurities in the threaded grooves of the threaded roller 3, thereby improving the service life of the equipment.

[0030] In this embodiment, one end of the take-up roller 13 is connected to a motor 1301.

[0031] In this embodiment, the threaded roller 3 is rotatably connected to two ends of a support column 301, the support column 301 is fixedly connected to the main body 2, the bottom of the main body 2 is equipped with a base 1, and the bottom of the base 1 is equipped with a support leg 101.

[0032] In this embodiment, several brushes 401 are distributed on the brush roller 4. The tail of the brush 401 makes slight contact with the surface of the threaded roller 3 to avoid excessive force and friction damage to the threaded roller 3.

[0033] In this embodiment, both ends of the brush roller 4 are connected to bearings 402, the bearings 402 are fixedly connected to the support column 301, and a servo motor 403 is installed on one of the bearings 402.

[0034] In this embodiment, several air nozzles 501 are distributed on the high-pressure pipe 5. One end of the high-pressure pipe 5 is connected to an air pressure pump 502. The direction of the air nozzles 501 is opposite to that of the threaded groove, and the counter-current will make the impurities blown away more cleanly.

[0035] In this embodiment, a top frame 8 is fixedly installed on the top of the main body 2, a cylinder 801 is installed on the lower surface of the top frame 8, a connecting block 802 is installed below the cylinder 801, an L-shaped insert plate 803 is installed on the right end of the connecting block 802, and a pressure plate 10 is connected to the lower end of the L-shaped insert plate 803. The L-shaped insert plate 803 is designed to facilitate timely replacement.

[0036] In this embodiment, an operating table 11 is fixedly connected to the middle of the main body 2 and is located below the pressure plate 10. Limiting plates 9 are installed on both sides of the operating table 11 that are perpendicular to the film conveying direction, which can precisely constrain the film conveying path and avoid problems such as film deviation or skewing before lamination.

[0037] In this embodiment, a bidirectional threaded shaft 7 is installed at one end of the limiting plate 9 near the threaded roller 3. Both ends of the bidirectional threaded shaft 7 pass through the limiting plate 9 and the main body 2, and are equipped with handwheels 701. Through the threaded connection structure between the bidirectional threaded shaft 7 and the limiting plate 9, rotating the handwheels 701 at both ends can drive the two limiting plates 9 to move laterally relative to each other or towards each other, thereby adjusting the distance between the two limiting plates 9.

[0038] In this embodiment, limit rods 201 are installed on both sides of the bidirectional threaded shaft 7. The two ends of the limit rods 201 are fixedly connected to the main body 2. The limit rods 201 can restrict the movement trajectory of the limit plate 28.

[0039] In this embodiment, conveying rollers 6 are installed on both sides of the operating table 11 along the film conveying direction to convey the film.

[0040] In this embodiment, a pressing device 12 is installed between the conveying roller 6 and the winding roller 13. The pressing device 12 includes a first U-shaped frame 1201 and a second U-shaped frame 1202. Pressure rollers 1203 are installed in both the first U-shaped frame 1201 and the second U-shaped frame 1202 to further flatten and adhere the film layer.

[0041] In this embodiment, the first U-shaped frame 1201 is connected to electric push rods 1205 at both ends, and the second U-shaped frame 1202 is fixedly connected to the main body 2, and its two ends are rotatably connected to the first U-shaped frame 1201 through cylinders 1204. The electric push rods 1205 drive the first U-shaped frame 1201 to adjust its height up and down, so that it can be adjusted according to the PE film of different thicknesses.

[0042] The working principle of this utility model is as follows: The film is extended by the threaded roller 3, and then the cylinder 801 is started to drive the pressure plate 10 to move downward, so that the pressure plate 10 presses the two layers of film together, initially flattening and bonding the PE film. After the film is flattened by the pressure plate 10, it is transported between the two pressure rollers 1203 by the conveying roller 6. The electric push rod 1205 drives the first U-shaped frame 1201 to adjust its height up and down, so that it can be adjusted according to the different thicknesses of PE film, further evenly bonding the two layers of film. Finally, the motor 1301 is started to wind up the PE film through the winding roller. During this process, the servo motor 403 is started to make the brush roller 4 drive the brush 401 to rotate together. The tail of the brush 401 cleans the surface debris of the rotating threaded roller 3. At the same time, the air pressure pump 502 is turned on, so that the high-pressure airflow is sprayed out along the air nozzle 501 and blows in the opposite direction along the threaded groove on the threaded roller 3 to further remove the stubborn impurities attached to the deep groove.

[0043] The design of the brush roller 4 and the high-pressure pipe 5 can remove impurities on the threaded roller 3, improve the service life and efficiency of the equipment, and at the same time avoid problems that affect the quality of the finished PE film.
