Description

Technical Field

[0001] This invention relates to the field of coating machine technology, specifically to a coating machine for preparing easily curable and removable self-adhesive films. Background Technology

[0002] A laminating machine is a device that laminates multiple layers of film together. Polyvinyl chloride (PVC) self-adhesive film is widely used for the adhesive protection of the surfaces of doors, windows and building materials. PVC self-adhesive film is obtained by coating a solvent-free pressure-sensitive adhesive onto a PVC film, then laminating a release paper onto the PVC film, and finally heating to cure the solvent-free pressure-sensitive adhesive.

[0003] The existing laminating machines have the following drawbacks:

[0004] The prior art CN117183556A discloses a hot melt adhesive film laminating machine, which includes a machine base, a first feeding component, a sol component, an adhesive application component, a cooling roller component, a cutting component, a laminating component, a second feeding component, and a unloading component. A gantry frame is provided on the machine base, positioned above the machine base. The sol component is mounted on the gantry frame. This invention allows for the feeding of two different films via the first and second feeding components. The film from the second feeding component is cut, then cooled by the cooling roller, and then fed again by the adhesive application component. The film is then laminated by the laminating component, and finally unloaded by the unloading component. This invention allows for tension adjustment via the first, second, and unloading components, and enables fully automated production, facilitating use and processing.

[0005] In the above-mentioned technology, when laminating the film, adhesive residue left from the film will remain on the pressure roller. When too much adhesive accumulates on the pressure roller, it can easily contaminate other surfaces of the film. Therefore, a laminating machine for preparing self-adhesive film that can easily cure and remove the residual adhesive on the pressure roller is needed to solve this problem.

[0040] Please see Figure 1An embodiment of the present invention provides a laminating machine for preparing an easily curable and removable self-adhesive film. Multiple support columns 2 are symmetrically installed at the bottom of the plate 1, and a frame 4 is installed at the top of the plate 1. The frame 4 is located in front of the frame 3 14.

A unwinding rod 6 is installed at the output end of the motor 5, and one end of the unwinding rod 6 penetrates the inner wall of the right side of the frame 4.

[0041] Furthermore, the support column 2 serves to support the frame 4. After the PVC film roll is placed outside the unwinding rod 6, the controller 3 controls the motor 5 to drive the unwinding rod 6 to rotate, thereby unwinding the PVC film and allowing it to move backward.

[0042] Please see Figure 1 and Figure 2 An embodiment of the present invention provides a laminating machine for preparing an easily curable and removable self-adhesive film. A second frame 7 is installed on the top of the plate 1, and the second frame 7 is located between the first frame 4 and the third frame 14. A second motor 8 is installed on the right side of the second frame 7. The second motor 8 is electrically connected to the controller 3. A unwinding rod 9 is installed at the output end of the second motor 8, and one end of the unwinding rod 9 penetrates the inner wall of the right side of the second frame 7. A glue box 10 is installed on the top of the second frame 7. An output pipe 11 is installed at the front output end of the glue box 10. A solenoid valve 12 is installed at the output end of the output pipe 11, and the solenoid valve 12 is electrically connected to the controller 3. A glue injection pipe 13 is installed at the output end of the solenoid valve 12.

[0043] Furthermore, the frame 2 7 can provide an installation position for the motor 2 8 and the glue box 10. The motor 2 8 can drive the unwinding rod 2 9 to rotate. The unwinding rod 2 9 can provide a placement position for the release paper roll. When the unwinding rod 2 9 rotates, the release paper can move backward. The controller 3 controls the solenoid valve 12 to open. Then the glue in the glue box 10 enters the solenoid valve 12 through the output pipe 11, and then is discharged from the glue injection pipe 13 and flows above the polyvinyl chloride film.

[0044] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5One embodiment of the present invention provides a laminating machine for preparing an easily curable and removable self-adhesive film. A controller 3 is mounted on the top of a plate 1. A frame 14 is mounted on the top of the plate 1. A pressure roller 16 is movably mounted through the inner side of the frame 14. A motor 15 is mounted on the right side of the frame 14, and the output end of the motor 15 is connected to one end of the pressure roller 16. The motor 15 is also electrically connected to the controller 3. A hydraulic cylinder 17 is mounted on the top of the frame 14, and the hydraulic cylinder 17 is electrically connected to the controller 3. A piston rod 18 is mounted on the output end of the hydraulic cylinder 17, and one end of the piston rod 18 is fitted with... There is a frame 19, which is located inside the frame 14. A pressure roller 20 is movably installed through the inside of the frame 19. Blocks 21 are symmetrically installed on the front of the frame 19. A scraping mechanism is provided on the inside of the block 21. The scraping mechanism includes a rectangular frame 22 and a scraper 23. The rectangular frame 22 is installed inside the two blocks 21. The scraper 23 is installed through the front of the rectangular frame 22, and the back of the scraper 23 contacts the outside of the pressure roller 20. Multiple bolts 24 are installed through the top of the rectangular frame 22. A pressure plate 25 is installed at one end of the bolts 24, and the pressure plate 25 is located inside the rectangular frame 22.

[0045] Furthermore, frame 3 14 provides an installation position for hydraulic cylinder 17. After the solventless pressure-sensitive adhesive in the dispensing tube 13 flows onto the polyvinyl chloride (PVC) film, the PVC film and release paper move backward synchronously into the space between pressure roller 1 16 and pressure roller 2 20. Then, controller 3 controls hydraulic cylinder 17 to move piston rod 1 18 downward, which in turn moves frame 19 downward. The downward movement of frame 19 moves pressure roller 2 20 downward, causing pressure roller 2 20 and pressure roller 1 16 to press the PVC film and release paper together, thus bonding the PVC film and release paper together. Motor 3 15 drives pressure roller 1 16 to rotate, which in turn causes the self-adhesive film between pressure roller 1 16 and pressure roller 2 20 to move backward. As for the residual adhesive flowing from the PVC film onto pressure roller 1 16 and pressure roller 2 20, scraper 1 23 first removes the adhesive from the pressure rollers. The residual adhesive on scraper 20 is scraped off and falls onto scraper 29. Scraper 29 then moves left and right to scrape off the adhesive on scraper 123 and push it into collection frame 32. The adhesive on pressure roller 16 is scraped off by scraper 34 and falls into collection frame 32. Block 21 can provide installation positions for motor 426, support block 28, laser rangefinder 30 and rectangular frame 22. Bolt 124 can drive pressure plate 25 to move downward by rotation, thereby squeezing and fixing scraper 123. When scraper 123 wears and does not contact pressure roller 20, the fixing of scraper 123 can be released by rotating bolt 124 in the opposite direction. Then scraper 123 can be moved backward to re-contact pressure roller 20, which can ensure that scraper 123 effectively scrapes off the residual adhesive on the surface of pressure roller 20.

[0046] Please see Figure 1, Figure 3 and Figure 4 An embodiment of the present invention provides a laminating machine for preparing an easily curable and removable self-adhesive film. A motor 26 is installed on the top of the right block 21. The motor 26 is electrically connected to the controller 3. A lead screw 27 is installed at the output end of the motor 26. A scraper 29 is installed on the outside of the lead screw 27, and the bottom of the scraper 29 is in contact with the top of the scraper 23. A support block 28 is installed on the top of the left block 21, and the support block 28 is located outside the lead screw 27. A laser rangefinder 30 is installed on the top of the left block 21, and the laser rangefinder 30 is located to the left of the scraper 29. The laser rangefinder 30 is electrically connected to the controller 3.

[0047] Furthermore, motor 26 can convert electrical energy into kinetic energy, thereby driving lead screw 27 to rotate. The rotation of lead screw 27 can drive scraper 29 to move left and right, so that scraper 29 can scrape off the glue on scraper 1 23 and scrape the glue on scraper 1 23 into collection frame 32. Support block 28 serves to support one end of lead screw 27 to prevent lead screw 27 from sagging. Laser rangefinder 30 is used to detect the position of scraper 29, and the front of scraper 29 is in contact with the front of rectangular frame 22, thereby preventing scraper 29 from rotating after it falls off and comes into contact with scraper 1 23.

[0048] Please see Figure 1 , Figure 3 and Figure 6 An embodiment of the present invention provides a laminating machine for preparing an easily curable and removable self-adhesive film.

A scraper 34 is installed on the top of the collection frame 32. A cylinder 35 is installed on the right side of the collection frame 32. The cylinder 35 is electrically connected to the controller 3. A piston rod 36 is installed at the output end of the cylinder 35, with one end of the piston rod 36 penetrating one side of the inner wall of the collection frame 32. A push rod 37 is installed at one end of the piston rod 36 and is located inside the collection frame 32.

[0049] Furthermore, the collection frame 32 is used to collect the glue that falls from the pressure roller 16 and the pressure roller 20. The limiting rod 31 can limit the collection frame 32. The bolt 2 33 can be inserted into the holes on both sides of the collection frame 32 by rotation to position the collection frame 32 and prevent the collection frame 32 from moving. The scraper 34 can scrape off the glue on the outside of the pressure roller 16 so that the glue falls into the collection frame 32. The cylinder 35 can drive the piston rod 2 36 to move left and right, which in turn drives the push rod 37 to move left and right. The left and right movement of the push rod 37 can push the glue that has fallen into the collection frame 32 flat, thereby preventing the glue from overflowing from the collection frame 32.

[0050] Please see Figure 1 and Figure 7 One embodiment of the present invention provides a laminating machine for preparing an easily curable and removable self-adhesive film. A drying chamber 38 is installed on the top of the plate 1, and the drying chamber 38 is located behind the frame 14. An inlet 39 is opened through the front of the drying chamber 38, and an outlet 40 is opened through the back of the drying chamber 38. Baking lamps 41 are symmetrically installed on the top inner wall and the bottom inner wall of the drying chamber 38. The baking lamps 41 are electrically connected to the controller 3. Multiple infrared thermometers 42 are symmetrically installed on the front inner wall and the back inner wall of the drying chamber 38. The upper and lower infrared thermometers 42 are arranged facing each other, and the infrared thermometers 42 are electrically connected to the controller 3.

[0051] Furthermore, the drying chamber 38 provides space for the thermal curing of the solvent-free pressure-sensitive adhesive on the PVC film, the inlet 39 provides a path for the composite self-adhesive film to enter the drying chamber 38, the outlet 40 provides a path for the composite self-adhesive film to leave the drying chamber 38, the heating lamp 41 can convert electrical energy into heat energy to heat the self-adhesive film entering the drying chamber 38, so that the adhesive in the self-adhesive film is heated and cured, and the infrared thermometer 42 can detect the temperature of the surface of the self-adhesive film.

[0052] Please see Figure 1 and Figure 8 An embodiment of the present invention provides a laminating machine for preparing an easily curable and removable self-adhesive film. A frame 43 is installed on the top of the plate 1 and is located behind the drying chamber 38. A motor 44 is installed on the right side of the frame 43. The motor 44 is electrically connected to the controller 3. A winding rod 45 is installed at the output end of the motor 44, and one end of the winding rod 45 penetrates the inner wall of the right side of the frame 43.

[0053] Furthermore, the frame 43 can provide an installation position for the motor 44, which can convert electrical energy into kinetic energy, thereby driving the winding rod 45 to rotate. The winding rod 45 can wind up the self-adhesive film by rotating.

[0054] The method of using a laminating machine for preparing easily curable and removable self-adhesive films is as follows:

[0055] S1. Place the PVC film roll outside the unwinding rod 6 and the release paper roll outside the unwinding rod 9. Then, the PVC film outside the unwinding rod 6 moves backward and passes under the glue injection tube 13. The glue injection tube 13 injects glue into the surface of the PVC film. Then, the PVC film continues to move backward. At the same time, the release paper outside the unwinding rod 9 moves backward synchronously above the PVC film and enters between the pressure roller 16 and the pressure roller 20.

[0056] S2. Then, the pressure roller 20 moves down to press the release paper, pressing the release paper and the polyvinyl chloride film together. The self-adhesive film continues to move backward into the drying chamber 38 to allow the adhesive to cure by heat.

[0057] S3. Then the composite self-adhesive film comes out from the outlet 40 of the drying chamber 38, and then the self-adhesive film is wound up on the outside of the winding bar 45.

[0058] S2 also includes the following steps:

[0059] S21, scraper 1 23 scrapes off the residual adhesive on the surface of pressure roller 2 20, and scraper 3 34 scrapes off the residual adhesive on the surface of pressure roller 1 16, after which the adhesive drips into the collection frame 32;

[0060] S22, scraper 29 moves left and right to scrape off the glue on top of scraper 1 23 and scrape the glue off scraper 1 23 into the collection box 32. Then push rod 37 moves left and right to push the glue in the collection box 32 flat.

[0061] Working Principle: Before using the self-adhesive film preparation laminating machine, check for any issues that might affect its use. Place the PVC film roll outside the unwinding rod 6 and the release paper roll outside the unwinding rod 9. The PVC film outside the unwinding rod 6 moves backward past the glue injection tube 13, which injects glue onto the PVC film surface. The PVC film continues to move backward, while the release paper outside the unwinding rod 9 moves backward above the PVC film and enters between the pressure rollers 16 and 20. The pressure roller 20 then moves down to press the release paper. The paper presses the release paper and PVC film together, while scraper 1 23 scrapes off the residual adhesive on the surface of pressure roller 20. Scraper 3 34 scrapes off the residual adhesive on the surface of pressure roller 16, and the adhesive drips into collection frame 32. Scraper 2 29 moves left and right to scrape off the adhesive on top of scraper 1 23 and scrape the adhesive off scraper 1 23 and let it fall into collection frame 32. Then push rod 37 moves left and right to push the adhesive that has fallen into collection frame 32 flat. The composite self-adhesive film continues to move backward into drying chamber 38 for heat curing of the adhesive.
