Description

Technical Field

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

[0002] During the slitting process of photosensitive dry films, some waste scraps are usually generated. Photosensitive dry films generally consist of a PE layer, a photosensitive glue layer, and a PET layer. Since the photosensitive glue layer belongs to special waste, before recycling the photosensitive dry film, it is necessary to separate the photosensitive dry film. However, due to the relatively tight connection between the photosensitive glue layer and the PET layer, some photosensitive glue still remains on the surface of the PET layer after separation, which makes it easy for the PET layer 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); this device sprays a professional cleaning solution 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 with a scraper to scrape off the photosensitive glue on the surface of the PET layer, so as to clean the residual photosensitive glue on the PET layer. However, this device only simply sprays the cleaning solution on the surface of the PET layer. In this extremely short period of time, the cleaning solution has not completely dissolved the photosensitive glue remaining on the surface of the PET layer, and only the surface layer of the photosensitive glue will be dissolved. Therefore, only the surface layer of the photosensitive glue can be scraped off by the scraper, and the lower layer of the photosensitive glue still adheres to the surface of the PET layer, and the cleaning effect is not ideal. Some photosensitive glue still remains on the surface of the PET layer and needs to be improved. Summary of the Invention

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

[0005] The technical solution is: An automatic recycling device for photosensitive dry films, including a box body, a mounting frame, a unwind roller, a PE layer winding roller, and a photosensitive glue layer winding roller; the box body is fixedly connected with the mounting frame; the mounting frame is provided with the unwind roller; the mounting frame is provided with the PE layer winding roller; the mounting frame is provided with the photosensitive glue layer winding roller; it further includes a guide roller 1, a guide roller 2, a guiding roller, a PET layer winding roller, and a flushing plate; the box body is provided with a plurality of symmetrically distributed guide rollers 1; the box body is provided with a plurality of symmetrically distributed guide rollers 2; the box body is provided with a plurality of vertically staggered guiding rollers; the mounting frame is provided with the PET layer winding roller; the box body is provided with a plurality of flushing plates, and the flushing plates cooperate with the guiding rollers.

[0006] Furthermore, the box body is fixedly connected with a plurality of partition plates, and the partition plates cooperate with the guiding rollers.

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

[0008] Further, the box body is provided with a plurality of heating bars distributed in a horizontal array.

[0009] Further, the electric drive stirring roller is close to the heating bar.

[0010] Further, the partition plate is provided with empty slots; the box body is fixedly connected with a hollow plate, and the PET film passes through the hollow plate after exposing from the box body.

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

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

[0013] Further, the hollow plate is provided with a plurality of air permeable slots.

[0014] The beneficial effects of the present invention are as follows: 1. By extending the moving path of the PET film, the time for the PET film to be soaked and dissolved by the cleaning solution is prolonged, so that the photosensitive glue on the surface of the PET film can be fully dissolved with the cleaning solution in the box body, thereby improving the cleaning effect on the residual photosensitive glue on the surface of the PET film. Whenever the PET film passes through the upper half of the upper guiding roller, the flushing plate is controlled to extract the cleaning solution from the box body, and then high-pressure cleaning solution is output from top to bottom to the PET film passing through the upper half of the upper guiding roller. Thus, 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 layer of the PET film can quickly detach from the PET film, so that the photosensitive glue on the lower layer of the PET film can be exposed, and the photosensitive glue on the lower layer can be fully dissolved by the cleaning solution in the box body during the subsequent soaking process, further improving the cleaning effect on the residual photosensitive glue on the surface of the PET film.

[0015] 2. By controlling the electric drive stirring roller to rotate rapidly, the solution is stirred to impact the back surface of the PET film, and a slapping force is applied to the back surface of the PET film, so that the residual photosensitive glue on the PET film can be slapped and vibrated, so that the photosensitive glue that has been dissolved during the soaking process on the surface layer of the PET film can quickly detach from the surface of the PET film, 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.

[0016] 3. By heating the solution in the box body from bottom to top with the heating bars, the temperature of the cleaning solution in the box body rises. By increasing the temperature of the cleaning solution, the movement speed of molecules can be increased, thereby accelerating the dissolution process of the photosensitive glue.

[0017] 4. In the present invention, the cleaning solution in the box will generate high-temperature water vapor under the heating of the heating strip. The water vapor will rise upward through the empty slots and then be intercepted by the hollow plate, adhering 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. Thus, the waste heat of the cleaning solution in the box is utilized to dry the PET film, saving costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following is only a preferred embodiment of the present invention, and does not limit the protection scope of the present invention accordingly.

[0024] Embodiment 1

[0025] An automatic recycling device for photosensitive dry film, as Figures 1 - 4 shown, includes a box 1, a mounting frame 2, an unwinding roller 3, a PE layer winding roller 4, and a photosensitive adhesive layer winding roller 5; the box 1 is bolted to the mounting frame 2; the mounting frame 2 is provided with the unwinding roller 3; the mounting frame 2 is provided with the PE layer winding roller 4; the mounting frame 2 is provided with the photosensitive adhesive layer winding roller 5;

[0026] It also includes a first guiding roller 6, a second guiding roller 7, a guiding roller 8, a PET layer winding roller 9 and a flushing plate 10; at least two symmetrically distributed first guiding rollers 6 are installed on the box body 1; at least two symmetrically distributed second guiding rollers 7 are installed on the box body 1; at least seven vertically staggered guiding rollers 8 are installed on the box body 1; the PET layer winding roller 9 is installed on the mounting frame 2; at least two flushing plates 10 are installed on the box body 1, and the flushing plates 10 cooperate with the guiding rollers 8.

[0027] At least three partition plates 11 are fixedly connected to the box body 1, and the partition plates 11 cooperate with the guiding rollers 8. The flushing area of the flushing plate 10 is covered by the partition plates 11 to prevent the high-pressure cleaning solution ejected by the flushing plate 10 from diffusing outward and polluting the working environment.

[0028] At least four electrically driven stirring rollers 20 are installed on the box body 1.

[0029] The working process of the present invention is as follows:

[0030] First, inject a cleaning solution into the box body 1 so that the liquid level height of the cleaning solution is flush with the center point of the upper guiding roller 8 above, so that the upper half of the upper guiding roller 8 is exposed above the liquid level;

[0031] Next, refer to 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 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 the photosensitive adhesive film 002 through the photosensitive adhesive layer winding roller 5; and make the PET film 003 first bypass the left first guiding roller 6 and the left second guiding roller 7, then bypass all the guiding rollers 8 from left to right in sequence, then bypass the right second guiding roller 7 and the right first guiding roller 6, and finally connect to the PET layer winding roller 9, and wind the PET film 003 through the PET layer winding roller 9.

[0032] In this process, the PET film 003 will be inside the box body 1 and move in a wavy shape from left to right between the guiding rollers 8. The PET film 003 is soaked by the cleaning solution in the box body 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 soaking and dissolving time of the PET film 003 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 body 1, thereby improving the cleaning effect on the photosensitive adhesive remaining on the surface of the PET film 003.

[0033] Meanwhile, since the upper half of the upper guiding roller 8 is exposed above the liquid level, every time the PET film 003 passes through the upper half of the upper guiding roller 8, this part of the PET film 003 will also be exposed above the liquid level. At this time, the control flushing plate 10 extracts the cleaning solution from the box body 1 and outputs a high-pressure cleaning solution from top to bottom to the PET film 003 passing through the upper half of the upper guiding roller 8. In this way, every time the PET film 003 is soaked for a period of time, it will be subjected to a high-pressure flushing, so that the photosensitive glue dissolved on the surface of the PET film 003 can quickly detach from the PET film 003, so that the photosensitive glue on the lower layer of the PET film 003 can be exposed, and 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, further improving the cleaning effect on the residual photosensitive glue on the surface of the PET film 003.

[0034] It should be noted that during the process of soaking and dissolving the PET film 003 with the cleaning solution in the box body 1, the electric drive stirring roller 20 is controlled to rotate rapidly, so as to stir the solution to impact the back surface of the PET film 003 and apply a slapping force to the back surface of the PET film 003, so that the residual photosensitive glue on the PET film 003 can be slapped and vibrated, so that the photosensitive glue that has been dissolved on the surface of the PET film 003 during the soaking process can quickly detach 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.

[0035] Embodiment 2

[0036] On the basis of the above Embodiment 1, as Figure 2 shown, the box body 1 is provided with at least ten heating strips 21 distributed in a horizontal array.

[0037] The electric drive 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 cleaning solution near the heating strip 21 that is heated is stirred upward through the electric drive stirring roller 20, so that the heat can be quickly conducted outward, reducing the required heating time.

[0038] The specific working process of the present invention is as follows:

[0039] In order to smoothly wind the PET film 003, generally, before the PET film 003 is wound, the PET film 003 is dried to remove the cleaning solution attached to the surface of the PET film 003. After the PET film 003 undergoes the soaking operation, more cleaning solution will adhere to its surface, making the drying difficult, time-consuming and inefficient;

[0040] Therefore, during the above-mentioned soaking and dissolving process, the solution in the box body 1 is heated from bottom to top by the heating strip 21, so that the temperature of the cleaning solution in the box body 1 rises. By increasing the temperature of the cleaning solution, the movement speed of molecules can be increased, thereby accelerating the dissolving process of the photosensitive glue.

[0041] Meanwhile, after the PET film 003 is exposed 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 start to evaporate. Since the temperature of the cleaning solution has been increased before, 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 movement of molecules, thus accelerating the escape speed of the molecules on the liquid surface. Therefore, its evaporation speed will be faster than that at a lower temperature, enabling the PET film 003 to be quickly dried in a short time, thereby improving the drying efficiency and recycling efficiency of the PET film 003.

[0042] Embodiment 3

[0043] On the basis of the above-mentioned Embodiment 2, as Figure 3 shown, the partition plate 11 is provided with an empty 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.

[0044] Before entering the box body 1, the PET film 003 passes through the hollow plate 30 first, and the unsoaked PET film 003 is preheated by the hollow plate 30 to increase the initial temperature of the photosensitive glue on the surface of the PET film 003, making it easier to dissolve, thereby improving the dissolving efficiency.

[0045] At least five heat-conducting fins 31 are fixedly connected between the hollow plate 30 and the partition plate 11 to improve the heat-conducting effect through the heat-conducting fins 31.

[0046] The hollow plate 30 is provided with a plurality of air-permeable grooves 3001.

[0047] The specific working process of the present invention is as follows:

[0048] 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 action of the heating strip 21, and the water vapor will pass upward through the empty slot 11001 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 upward through the ventilation slots 3001 and be discharged outward to avoid the retention of water vapor and affect the drying effect. In this way, the waste heat of the cleaning solution in the box body 1 is used to dry the PET film 003, saving costs.

[0049] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
