Description

Technical Field

[0001] The present invention relates to the technical field of photosensitive dry film production, and in particular to an automatic recycling device for photosensitive dry film. Background Art

[0002] In the process of cutting photosensitive dry film, some waste scraps are usually generated. Photosensitive dry film is usually composed of PE layer, photosensitive adhesive layer and PET layer. Since the photosensitive adhesive layer is a special waste, it is necessary to separate the photosensitive dry film before recycling it. However, since the photosensitive adhesive layer and the PET layer are closely connected, part of the photosensitive adhesive still remains on the surface of the PET layer after separation, making the PET layer easy to be included in the management of special waste. Therefore, before recycling the PET layer, it is usually necessary to clean and dry the PET layer.

[0003] Existing Chinese patent: A multifunctional photosensitive dry film collection device (CN118769426A); the device sprays a professional cleaning liquid on the PET layer to dissolve the photosensitive glue on the surface of the PET layer, and then scrapes the surface of the PET layer through a scraper to scrape off the photosensitive glue on the surface of the PET layer, thereby cleaning the residual photosensitive glue on the PET layer. However, the device simply sprays the cleaning liquid on the surface of the PET layer, and in this extremely short time, the cleaning liquid has not completely dissolved the residual photosensitive glue on the surface of the PET layer. Only the photosensitive glue on the surface will be dissolved. Therefore, only the photosensitive glue on the surface can be scraped off by the scraper, and the photosensitive glue on the lower layer is still attached to the surface of the PET layer. The cleaning effect is not ideal, and some photosensitive glue still remains on the surface of the PET layer, which needs to be improved. Summary of the invention

[0004] In order to overcome the disadvantages of the problems mentioned in the background, the present invention provides an automatic recycling device for photosensitive dry film.

[0005] The technical solution is: an automated recycling equipment for photosensitive dry film, including a box body, a mounting frame, a unwinding roller, a PE layer winding roller and a photosensitive adhesive layer winding roller; the box body is fixedly connected to the mounting frame; the mounting frame is equipped with an unwinding roller; the mounting frame is equipped with a PE layer winding roller; the mounting frame is equipped with a photosensitive adhesive layer winding roller; it also includes a guide roller 1, a guide roller 2, a guide roller, a PET layer winding roller and a flushing plate; the box body is equipped with a plurality of symmetrically distributed guide rollers 1; the box body is equipped with a plurality of symmetrically distributed guide rollers 2; the box body is equipped with a plurality of guide rollers that are staggered up and down; the mounting frame is equipped with a PET layer winding roller; the box body is equipped with a plurality of flushing plates, and the flushing plates cooperate with the guide rollers.

[0006] Furthermore, a plurality of partitions are fixedly connected to the box body, and the partitions are matched with the guide rollers.

[0007] Furthermore, the box body is equipped with a plurality of electrically driven stirring rollers.

[0008] Furthermore, the box body is provided with a plurality of heating strips distributed in a transverse array.

[0009] Further, an electrically driven agitating roller is located adjacent to the heating strip.

[0010] Furthermore, the partition is provided with a hollow groove; the box body is fixed with a hollow plate, and the PET film passes through the hollow plate after being exposed from the box body.

[0011] Further, the PET film passes through the hollow plate before entering the box.

[0012] Furthermore, a plurality of heat-conducting fins are fixedly connected between the hollow plate and the partition plate.

[0013] Furthermore, the hollow plate is provided with a plurality of ventilation grooves.

[0014] The beneficial effects of the present invention are as follows: 1. The present invention prolongs the time for the PET film to be soaked and dissolved by the cleaning solution by prolonging the moving distance of the PET film, so that the photosensitive glue on the surface of the PET film can be fully dissolved with the cleaning solution in the box, thereby improving the cleaning effect of the residual photosensitive glue on the surface of the PET film. Whenever the PET film passes through the upper half of the upper guide roller, the flushing plate is controlled to extract the cleaning solution from the box, and then the high-pressure cleaning solution is output from top to bottom to the PET film passing through the upper half of the upper guide roller. In this way, whenever the PET film is soaked for a period of time, it will be subjected to a high-pressure flushing, so that the dissolved photosensitive glue on the surface of the PET film is quickly separated from the PET film, so that the photosensitive glue on the lower layer of the PET film can be exposed, so that the photosensitive glue on the lower layer can be fully dissolved by the cleaning solution in the box during the subsequent soaking process, further improving the cleaning effect of the residual photosensitive glue on the surface of the PET film.

[0015] 2. The present invention controls the electrically driven stirring roller to rotate rapidly, thereby stirring the solution to impact the back side of the PET film, applying a slapping force to the back side of the PET film, so that the photosensitive adhesive remaining on the PET film can be slapped and vibrated, so that the photosensitive adhesive on the surface of the PET film that has been dissolved during the immersion process can be quickly separated from the surface of the PET film, and the cleaning solution can better penetrate into the photosensitive adhesive layer, thereby improving the dissolution effect and dissolution speed of the cleaning solution on the photosensitive adhesive on the surface of the PET film.

[0016] 3. The present invention heats the solution in the box from bottom to top through the heating strip, so that the temperature of the cleaning solution in the box rises. By increasing the temperature of the cleaning solution, the movement speed of the molecules can be increased, thereby accelerating the dissolution process of the photosensitive adhesive.

[0017] 4. In the present invention, the cleaning solution in the box body will generate high-temperature water vapor under the heating effect of the heating strip, and pass through the hollow groove upward, and then be intercepted by the hollow plate and attached to the bottom surface of the hollow plate. The hollow plate will absorb the heat contained in the water vapor and conduct the heat toward the inside of the hollow plate, so that the hollow area inside the hollow plate reaches a certain temperature. In this way, when the PET film passes through the hollow area inside the hollow plate, it will be dried by the hollow plate. In this way, the residual heat of the cleaning solution in the box is used to dry the PET film, saving costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.

[0021] Example 1 An automated recycling device for photosensitive dry film, such as Figure 1-Figure 4 As shown, it includes a box body 1, a mounting frame 2, a reeling roller 3, a PE layer reeling roller 4 and a photosensitive adhesive layer reeling roller 5; the box body 1 is bolted with the mounting frame 2; the mounting frame 2 is installed with the reeling roller 3; the mounting frame 2 is installed with the PE layer reeling roller 4; the mounting frame 2 is installed with the photosensitive adhesive layer reeling roller 5; It also includes a guide roller 1 6, a guide roller 2 7, a guide roller 8, a PET layer winding roller 9 and a flushing plate 10; the box body 1 is installed with at least two symmetrically distributed guide rollers 6; the box body 1 is installed with at least two symmetrically distributed guide rollers 2 7; the box body 1 is installed with at least seven guide rollers 8 that are staggered up and down; the mounting frame 2 is installed with a PET layer winding roller 9; the box body 1 is installed with at least two flushing plates 10, and the flushing plates 10 cooperate with the guide rollers 8.

[0022] At least three partitions 11 are fixedly connected to the box body 1, and the partitions 11 cooperate with the guide rollers 8 to cover the flushing area of ​​the flushing plate 10 to prevent the high-pressure cleaning solution flushed out of the flushing plate 10 from diffusing outward and polluting the working environment.

[0023] The housing 1 is equipped with at least four electrically driven stirring rollers 20 .

[0024] The present invention works specifically as follows: First, a cleaning solution is injected into the box 1 so that the liquid level of the cleaning solution is flush with the center point of the upper guide roller 8, so that the upper half of the upper guide roller 8 is exposed from the liquid surface; Next, see Figure 2 and Figure 4 , place the photosensitive dry film to be recycled on the unwinding roller 3, connect the PE film 001 in the photosensitive dry film to the PE layer winding roller 4, and wind up the PE film 001 through the PE layer winding roller 4; connect the photosensitive adhesive film 002 in the photosensitive dry film to the photosensitive adhesive layer winding roller 5, and wind up the photosensitive adhesive film 002 through the photosensitive adhesive layer winding roller 5; and make the PET film 003 first bypass the left guide roller 1 6 and the left guide roller 2 7, and then bypass all the guide rollers 8 from left to right in turn, and then bypass the right guide roller 2 7 and the right guide roller 1 6, and finally connect to the PET layer winding roller 9, and wind up the PET film 003 through the PET layer winding roller 9.

[0025] During this process, the PET film 003 will move in a wave-like manner from left to right in the box 1 and between the guide rollers 8. The PET film 003 will be immersed in the cleaning solution in the box 1 to dissolve the photosensitive adhesive remaining on the surface of the PET film 003. In this way, by extending the moving distance of the PET film 003, the time for the PET film 003 to be immersed and dissolved by the cleaning solution is extended, so that the photosensitive adhesive on the surface of the PET film 003 can be fully dissolved with the cleaning solution in the box 1, thereby improving the cleaning effect of the residual photosensitive adhesive on the surface of the PET film 003.

[0026] At the same time, since the upper half of the upper guide roller 8 will be exposed to the liquid surface, whenever the PET film 003 passes through the upper half of the upper guide roller 8, this part of the PET film 003 will also be exposed to the liquid surface. At this time, the control flushing plate 10 is to extract the cleaning solution from the box body 1, and then output the high-pressure cleaning solution to the PET film 003 passing through the upper half of the upper guide roller 8 from top to bottom. In this way, whenever the PET film 003 is soaked for a period of time, it will be subjected to a high-pressure flushing, so that the dissolved photosensitive glue on the surface of the PET film 003 can quickly separate from the PET film 003, so that the photosensitive glue on the lower layer of the PET film 003 can be exposed, so that the photosensitive glue on the lower layer can be fully dissolved by the cleaning solution in the box body 1 during the subsequent soaking process, thereby further improving the cleaning effect of the residual photosensitive glue on the surface of the PET film 003.

[0027] It should be noted that, in the process of soaking and dissolving the PET film 003 with the cleaning solution in the box 1, the electrically driven stirring roller 20 is controlled to rotate rapidly, so that the stirring solution impacts the back side of the PET film 003, and a beating force is applied to the back side of the PET film 003, so that the photosensitive glue remaining on the PET film 003 can be beaten and vibrated, so that the photosensitive glue on the surface of the PET film 003 that has been dissolved during the soaking process can be quickly separated from the surface of the PET film 003, so that the cleaning solution can better penetrate into the photosensitive glue layer, thereby improving the dissolution effect and dissolution speed of the cleaning solution on the photosensitive glue on the surface of the PET film 003.

[0028] Example 2 On the basis of the above-mentioned embodiment 1, Figure 2 As shown, the box body 1 is provided with at least ten heating strips 21 distributed in a transverse array.

[0029] The electrically driven stirring roller 20 is close to the heating strip 21. When the heating strip 21 heats the cleaning solution in the box body 1, the electrically driven stirring roller 20 stirs the heated cleaning solution near the heating strip 21 upward, so that the heat can be quickly transferred outward, thereby reducing the time required for heating.

[0030] The present invention works specifically as follows: In order to smoothly roll up the PET film 003, the PET film 003 is generally dried before being rolled up to remove the cleaning solution attached to the surface of the PET film 003. However, after the PET film 003 is soaked, more cleaning solution will be attached to the surface of the PET film 003, which makes drying difficult, time-consuming and inefficient. To this end, during the above-mentioned soaking and dissolving process, the solution in the box 1 is heated from bottom to top by the heating strip 21, so that the temperature of the cleaning solution in the box 1 rises. By increasing the temperature of the cleaning solution, the movement speed of the molecules can be increased, thereby accelerating the dissolution process of the photosensitive resin.

[0031] At the same time, when the PET film 003 emerges from the cleaning solution, a layer of cleaning solution will remain on its surface. As the PET film 003 is exposed to the air, this layer of residual solution will begin to evaporate. Since the temperature of the cleaning solution was previously increased, the temperature of the cleaning solution on the surface of the PET film 003 is also relatively high. The higher the temperature, the more intense the thermal motion of the molecules, thereby accelerating the escape speed of the molecules on the liquid surface. Therefore, its evaporation rate will be faster than at a lower temperature, so that the PET film 003 can be quickly dried in a short time, thereby improving the drying efficiency and recycling efficiency of the PET film 003.

[0032] Example 3 Based on the above embodiment 2, Figure 3 As shown, the partition plate 11 is provided with a hollow groove 11001 ; the box body 1 is bolted with a hollow plate 30 , and the PET film 003 passes through the hollow plate 30 after being exposed from the box body 1 .

[0033] Before entering the box body 1, the PET film 003 first passes through the hollow plate 30, and the unsoaked PET film 003 is preheated by the hollow plate 30 to increase the initial temperature of the photosensitive adhesive on the surface of the PET film 003, making it easier to dissolve, thereby improving the dissolution efficiency.

[0034] At least five heat-conducting fins 31 are fixedly connected between the hollow plate 30 and the partition plate 11 , and the heat-conducting fins 31 are used to improve the heat-conducting effect.

[0035] The hollow plate 30 is provided with a plurality of ventilation grooves 3001 .

[0036] The present invention works specifically as follows: Due to the presence of the heating strip 21, the cleaning solution in the box body 1 will generate high-temperature water vapor under the heating effect of the heating strip 21, and pass through the hollow groove 11001 upwards, and then be intercepted by the hollow plate 30, and adhere to the bottom surface of the hollow plate 30. The hollow plate 30 will absorb the heat contained in the water vapor and conduct the heat toward the inside of the hollow plate 30, so that the hollow area inside the hollow plate 30 reaches a certain temperature. In this way, when the PET film 003 passes through the hollow area inside the hollow plate 30, it will be dried by the hollow plate 30; at the same time, the water vapor generated by the evaporation of the cleaning solution on the surface of the PET film 003 will pass through the air permeable groove 3001 upwards and be discharged outwards, so as to avoid the retention of water vapor and affect the drying effect. In this way, the residual heat of the cleaning solution in the box body 1 is used to dry the PET film 003, saving costs.

[0037] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
