Description

Technical Field

[0001] The utility model relates to the technical field of drying boxes, in particular to a protective film drying processing box. Background Art

[0002] Protective films can be divided into digital product protective films, car protective films and food protective films according to their uses. However, due to the needs of the production process, the surface of some protective films usually contains more moisture or solvents, and they need to be dried using equipment such as drying ovens to make the surface of the protective film smooth and free of watermarks.

[0003] However, when drying, the existing protective film usually passes directly through the hot air area in the drying box without any protective measures such as tensioning. As a result, the protective film is prone to shaking when passing through the hot air area, which makes it more likely to have creases and curling when the protective film is subsequently rolled up. In addition, water vapor generated on the surface of the protective film during drying tends to accumulate on the top of the inner side of the drying box. After the temperature in the drying box drops, the high-temperature water vapor tends to condense into water droplets on the top of the inner side of the drying box, and drip into the drying box to form condensed water. When the drying box is subsequently started to heat, the water vapor circulates again in the drying box, affecting the drying speed of the drying box. Utility Model Content

[0024] like Figures 1 to 4As shown, the protective film drying treatment box of this embodiment includes a bottom box 6, the interior of the bottom box 6 is hollow, and the top surface of the bottom box 6 is the same size as the bottom surface of the top box 1, so that the top box 1 can be smoothly put on the bottom box 6, so that the interior of the bottom box 6 and the top box 1 are communicated, so that the hot air in the bottom box 6 can be blown into the top box 1, and a heating mechanism 13 is installed in the middle of the bottom box 6. The heating mechanism 13 includes an electric heating plate and a blower, so that hot air can be blown into the top box 1 for drying. A water storage tank 17 is provided on one side of the top of the bottom box 6, and a drain pipe is passed through the bottom of the water storage tank 17, which can discharge the collected steam water out of the drying box in time to keep the drying box dry. The top cover of the bottom box 6 is provided with a top box 1, and the top of the top box 1 is fixed A top cover 2 is fixedly connected, and the top cover 2 is a detachable structure, which is convenient for cleaning and replacing the sponge pad 8 that absorbs water. The bottom end of the top cover 2 is fixedly connected to the sponge pad 8. A film inlet 4 is provided at the bottom of one side wall of the top box 1, and a film outlet 12 is provided at the top of one side wall of the top box 1. The film inlet 4 and the film outlet 12 are the same size but at different heights, so that the protective film 9 entering and exiting the drying box can be kept in a tensioned state by means of a height difference, reducing the probability of the protective film 9 being shaken by hot air in the drying box. A guide roller 10 is provided on one side of the film inlet 4 and the film outlet 12. The guide roller 10 can make the protective film 9 slide smoothly toward the tensioning roller 11, and can cooperate with the tensioning roller 11 to tension the protective film 9;

[0025] The inner side of the top box 1 is rotatably connected to two tensioning rollers 11. The heights of the two tensioning rollers 11 are not at the same level, so that the length of the protective film 9 entering the drying box is longer than the length of the ordinary horizontal entry, so that the protective film 9 has sufficient time to dry in the drying box, which is more conducive to drying the protective film 9. The outer wall of the tensioning roller 11 is movably connected to the protective film 9. The outer sleeve of the tensioning roller 11 is provided with a water-absorbing sleeve 15. The water-absorbing sleeve 15 is made of a water-absorbing sponge, which can absorb the moisture on the surface of the protective film 9 in time, which is beneficial to To dry the moisture on the surface of the protective film 9, a plurality of through-tubes 18 are passed through the interior of the tensioning roller 11. The through-tubes 18 can drain the moisture squeezed out of the water absorption sleeve 15 into the hollow shaft 14, thereby ensuring the water absorption effect of the water absorption sleeve 15. A drainage channel 16 is provided on the inner wall of the top box 1. The drainage channel 16 can drain the moisture in the hollow shaft 14 to the water storage bin 17 for collection. The middle part of the tensioning roller 11 is passed through a hollow shaft 14, and the hollow shaft 14 can realize the drainage of moisture. A rotating motor 5 is fixedly installed on the front of the top box 1.

[0026] Specifically, a through hole 7 is provided in the middle of the top cover 2, a transparent box 3 is embedded in the top of the through hole 7, a moisture detection test paper is embedded in the interior of the transparent box 3, and an opening is provided at the bottom of the transparent box 3, which communicates with the through hole 7. When the sponge pad 8 is saturated with water, the moisture in the sponge pad 8 will enter the transparent box 3 through the through hole 7, causing the moisture detection test paper to change color, and the user can observe the color change of the transparent box 3 to wring out the moisture in the sponge pad 8 in time, thereby ensuring the water absorption effect of the sponge pad 8.

[0027] Furthermore, the output end of the rotating motor 5 is engaged with one of the hollow shafts 14, and the tensioning roller 11 is rotatably connected to the top box 1 through the rotating motor 5. The rotating motor 5 can drive the hollow shaft 14 to rotate, and drive the tensioning roller 11 near the film outlet 12 to rotate, thereby enabling the protective film 9 to pass through this drying and processing box.

[0028] Furthermore, the sponge pad 8 is located at the top of the inner side of the top box 1, and the sponge pad 8 is located at the bottom of the through hole 7. The thickness of the sponge pad 8 is relatively thin, but the water absorption capacity is better. It can absorb the high-temperature water vapor accumulated at the top of the inner side of the top box 1 to prevent the water vapor from condensing to form condensed water.

[0029] Furthermore, the guide roller 10 is movably embedded in the top box 1 through a fixed support cross bar, and the protective film 9 is movably connected to the guide roller 10. The guide roller 10 can enable the protective film 9 to pass through the top box 1 smoothly before and after drying, while keeping the protective film 9 in a tensioned state.

[0030] Furthermore, the through-tube 18 is movably connected to the hollow shaft 14, and a circular hole 19 is provided at the bottom of one end of the hollow shaft 14. The through-tube 18 can drain the water squeezed out of the water-absorbing sleeve 15 on the tensioning roller 11, so that the water in the water-absorbing sleeve 15 is not easy to return to the protective film 9, thereby facilitating the rapid drying of the moisture on the surface of the protective film 9.

[0031] Furthermore, the circular hole 19 is connected to the drainage channel 16, and the bottom of the drainage channel 16 is connected to the interior of the water storage tank 17. The drainage channel 16 can drain the water vapor in the hollow shaft 14 into the water storage tank 17, thereby reducing the moisture in the drying box, which is conducive to maintaining the dry state in the drying box, thereby avoiding the adverse effect of the moisture remaining in the drying box on the drying speed.

[0032] The method of using this embodiment is as follows: when using the protective film 9 drying treatment box, it is necessary to first connect the drying box to an external power supply so that the heating mechanism 13 and the rotating motor 5 start to run, and then the tensioning roller 11 driven by the rotating motor 5 will drive the protective film 9 that penetrates the top box 1 from the film inlet 4 to rotate along the guide roller 10 to the first tensioning roller 11, and then rotate to the second tensioning roller 11, and then slide out of the top box 1 from the film outlet 12 along the guide roller 10 at the film outlet 12, so that the protective film 9 remains in a tensioned state in the drying box, and at the same time, most of the moisture on the surface of the protective film 9 will be absorbed when it contacts the water absorption sleeve 15 on the surface of the tensioning roller 11, and then transmitted to the hollow shaft 14 through the through pipe 18, and then through the circular hole 1 connected to the drainage channel 16 at the end of the hollow shaft 14. 9 flows into the drainage channel 16, and then enters the water storage bin 17 from the drainage channel 16 to be collected and discharged out of the drying box from the drain pipe on the side of the water storage bin 17, and part of the water evaporated by heat will form high-temperature steam and float to the sponge pad 8 at the bottom of the top cover 2 and be absorbed by the sponge pad 8. After the sponge pad 8 is saturated with water, the high-temperature water vapor will enter the transparent box 3 through the through hole 7 on the top cover 2 and come into contact with the moisture detection paper in the transparent box 3, causing the moisture detection paper to change color. After using this drying box for a long time, the user can observe the color in the transparent box 3 through the top of the transparent box 3. After the color changes, the user can uncover the top cover 2 from the top of the top box 1, take out the sponge pad 8 on the top cover 2 that is saturated with water, squeeze out the water in the sponge pad 8 or replace it with a new sponge pad 8.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
