Technical Field

[0001] The utility model belongs to the field of packaging equipment, and particularly relates to an automatic dialysis paper pasting device for packaging film. Background Art

[0002] Dialysis paper, as the name implies, is a paper material with specific permeability. Its main feature is that it can allow certain substances (such as sterilization factors) to penetrate while blocking other substances (such as bacteria) from passing through. In some packages with specific requirements, dialysis paper needs to be pasted on the packaging film. For example, in medical packaging, it can improve the sterilization effect, ensure the aseptic state, and enhance the packaging performance. However, in the current packaging process, usually, dialysis paper is first manually pasted onto the packaging film, and then automatic packaging equipment is used for packaging. Manually pasting dialysis paper restricts production efficiency and product quality, and also requires a large amount of labor cost. Content of the Utility Model

[0023] As shown in the attached Figure 1-8 An automatic dialysis paper pasting device for a packaging film, which includes a dialysis paper assembly 2 arranged on one side of the packaging film assembly 1. A punching structure 3, a laminating structure 4 and a heat-sealing structure 5 are arranged on one side of the dialysis paper assembly 2. The dialysis paper assembly 2 includes a reel 8 rotatably installed in an installation box 7. A chute 9 extending axially is arranged on the outer surface of the reel 8. Two paper roll supports 10 are fixedly installed on the reel 8. The paper roll support 10 is provided with a fixing groove 11 matching the chute 9. The fixing groove 11 and the chute 9 are combined into a limiting groove. A limiting block (not shown in the figure) is fixedly installed in the limiting groove through a bolt penetrating the paper roll support 10. The limiting block and the limiting groove cooperate to limit the rotation of the paper roll support 10 relative to the reel 8. When the bolt is tightened, the bolt presses against the bottom of the limiting groove and fixes the paper roll support 10 and the limiting block. When the bolt is loosened, the paper roll support 10 and the limiting block can slide along the chute 9 to conveniently adjust the position of the dialysis paper roll 12 according to actual needs.

One end of the adjusting screw 15 away from the slide seat 14 extends outside the installation box 7 and is fixedly provided with a handle.

[0024] The punching structure 3 includes a support frame 16 fixedly installed on the outer surface of the installation box 7. The support frame 16 includes a fixed frame 17 and a movable frame 18. One end of the fixed frame 17 is fixedly connected to the installation box 7. Both the fixed frame 17 and the movable frame 18 are provided with mutually matching strip-shaped holes. The movable frame 18 is fixedly installed at one end of the fixed frame 17 away from the installation box 7 through the cooperation of bolts and the strip-shaped holes. A flywheel assembly for punching is installed at one end of the movable frame 18 away from the fixed frame 17. Loosening the bolts can move the movable frame 18 under the guidance of the strip-shaped holes, so that the relative distance between the flywheel assembly and the installation box 7 can be adjusted according to actual needs. The flywheel assembly includes an outer fixing member 19, a cutter wheel 20, and an inner fixing member 21. A bearing is installed on the movable frame 18. The inner fixing member 21 is provided with a shaft portion 22 and is rotatably connected to the bearing through the shaft portion 22. The outer fixing member 19, the cutter wheel 20, and the inner fixing member 21 are all provided with four mutually matching bolt holes. The outer fixing member 19 presses and fixes the cutter wheel 20 to the inner fixing member 21 through the cooperation of four bolts. A rubber roller 23 cooperating with the flywheel assembly is rotatably installed on one side of the installation box 7 where the support frame 16 is located. A protective cover 24 is fixedly installed on the other side of the installation box 7 relative to the rubber roller 23 where the support frame 16 is located, which can prevent injury caused by accidentally touching the flywheel assembly. The laminating structure 4 is a laminating roller.

[0025] The heat-sealing structure 5 includes a fixed seat 25 fixedly installed on the surface of the installation box 7. Two guiding optical axes 26 are provided on the fixed seat 25. The same sliding seat 28 is slidably installed on the two guiding optical axes 26 through linear bearings 27. An adjusting bolt 29 is rotatably installed on the sliding seat 28. The adjusting bolt 29 is threadedly connected to the fixed seat 25. A handle is also provided on the adjusting bolt 29. Rotating the adjusting bolt 29 through the handle can drive the sliding seat 28 to slide along the guiding optical axis 26. The sliding seat 28 is fixedly installed with a lower heat-sealing seat 30. An upper heat-sealing seat 31 is rotatably installed on the sliding seat 28 above the lower heat-sealing seat 30. Heat-sealing copper blocks 32 are installed on both the upper heat-sealing seat 31 and the lower heat-sealing seat 30. A heat-sealing motor 33 for driving the heat-sealing copper block 32 on the upper heat-sealing seat 31 to swing close to or away from the heat-sealing copper block 32 on the lower heat-sealing seat 30 is also fixedly installed on the sliding seat 28. The opening and closing of the heat-sealing structure 5 are controlled by the heat-sealing motor 33 to complete the heat-sealing and laminating work of the packaging film and the dialysis paper.

[0026] After being pulled out from the packaging film assembly 1, the packaging film extends to the punching structure 3. After punching, it then extends to the laminating structure 4. After being pulled out from the dialysis paper assembly 2, the dialysis paper extends to the laminating structure 4. The packaging film with the dialysis paper attached then extends to the heat-sealing structure 5.

[0027] As Figure 8As shown, the automatic dialysis paper pasting device provided in this embodiment is used in conjunction with an existing automatic packaging machine. First, adjust the positions of the dialysis paper roll 12, the packaging film roll, the flywheel assembly, and the heat-sealing assembly according to the actual packaging requirements. Then, pull out the packaging film, pull it onto the punching structure 3 and bypass the rubber roller 23, then pull it towards the laminating roller, and finally pull it towards the heat-sealing structure 5. Then, pull out the dialysis paper and pull it towards the laminating roller to laminate with the packaging film, then pull it towards the heat-sealing structure 5, and finally pull the packaging film and the dialysis paper towards the film feeding rack 6 of the automatic packaging machine, and the automatic packaging machine provides the power.

[0028] When the automatic packaging machine starts, it pulls the packaging film and the dialysis paper at the same time. During the movement of the packaging film, it drives the cutter wheel 20 to rotate, so as to punch strip-shaped holes in the packaging film to facilitate the penetration of the dialysis paper. The packaging film and the dialysis paper overlap on the laminating roller cylinder, and the dialysis paper is adjusted to just cover the strip-shaped holes. Finally, the packaging film and the dialysis paper are bonded together after passing through the heat-sealing copper block 32.
