Description

Technical Field

[0001] This utility model relates to the field of drying technology, specifically to a drying device for optical film production. Background Technology

[0002] Optical thin films are a type of optical medium material composed of multiple thin layers that propagate light beams through interfaces. Current optical films include different types such as reflective films, antireflective films, and polarizing films.

[0003] Optical films need to be dried during production because their surface contains tiny water droplets. However, current dryers use a single drying method, which leads to prolonged drying time and reduced drying efficiency. Therefore, a drying device for optical film production is proposed. Utility Model Content

[0004] The technical problem this invention aims to solve is that current dryers use a single drying method, which leads to prolonged drying time and reduced drying efficiency. This invention provides a drying device for optical film production that combines multiple methods to shorten the time required for traditional drying and can be adjusted as needed.

[0005] The technical solution adopted by this utility model to solve the technical problem is: a drying device for optical film production, including a dryer, a discharge cylinder detachably connected to the middle of one side wall of the dryer, a drying trough extending through the dryer, a cleaning plate rotatably connected to one end of the dryer and the two sides near the opening of the drying trough by a torsion spring, a sponge pad fixedly connected to one end of the cleaning plate, an air outlet opened on the side wall of the drying trough near the openings at both ends, the air outlets being staggered, and a heating tube embedded in the middle of the drying trough.

[0006] As a preferred embodiment of this utility model, a pair of fixed columns are fixedly connected to the two opposite side walls of the drying tank near both ends, and a rotating roller is rotatably connected between each pair of fixed columns, with the two rotating rollers in contact with each other.

[0007] As a preferred embodiment of this utility model, the dryer is detachably connected to a blower on the side away from the discharge cylinder and near both ends. The blower has a fan blade detachably connected to it via a motor. An electric heating plate is fixedly connected inside the blower and near the side wall of the dryer. Holes are provided on the electric heating plate. A flange is fixedly connected to the blower near the outer edge of the dryer, and the blower is detachably connected to the dryer via the flange.

[0008] As a preferred technical solution of this utility model, the dryer has an air trough inside near the drying tank, the air outlet is connected to the air trough, the number of air troughs is the same as the number of rows of air outlets, the dryer has an air inlet on the side wall opposite to the blower, the air trough is connected to the air inlet, the air inlet is connected to the inside of the blower, and the inner wall of the air outlet has an inclined structure.

[0009] As a preferred technical solution of this utility model, the discharge cylinder has an L-shaped structure and the interior of the discharge cylinder is in a through state. The side wall of the dryer opposite to the discharge cylinder is provided with a steam outlet groove, and the discharge cylinder is connected to the drying tank through the steam outlet groove.

[0010] This invention has the following advantages: the hot air blown out by the blower can not only dry the optical film, but also blow away or disperse the water droplets on the film into smaller droplets, improving the overall drying efficiency. Then, a secondary drying process can be carried out through the heating tube. With the water droplets blown away or reduced to a smaller volume, the heating tube can effectively dry the film. Finally, the optical film passing through the middle of the heating tube will be treated by the hot air, enhancing the drying effect. This can effectively improve the drying efficiency, and the hot air intensity and temperature can be adjusted as needed. At the same time, the irradiation temperature of the heating tube can also be adjusted, increasing the flexibility and adaptability of the application. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] Please refer to the following: Figure 1-3This utility model discloses a drying device for optical film production, including a dryer 1. A discharge cylinder 3 is detachably connected to the middle of one side wall of the dryer 1. A drying trough 14 is opened through the dryer 1. A cleaning plate 4 is rotatably connected to the two sides of the dryer 1 near the opening of the drying trough 14 by a torsion spring. A sponge pad 5 is fixedly connected to one end of the cleaning plate 4. An air outlet 8 is opened on the side wall of the drying trough 14 near the openings at both ends. The air outlets 8 are staggered. A heating tube 9 is embedded in the middle of the drying trough 14. A pair of fixed columns 6 are fixedly connected to the two opposite side walls of the drying trough 14 near the two ends. A rotating roller 7 is rotatably connected between each pair of fixed columns 6. The two rotating rollers 7 are in contact with each other.

[0017] The technical effects of this solution are as follows: activating the heating tube 9 allows for the irradiation and drying of the optical film passing through it. Air outlets 8 are opened on the opposite upper and lower sidewalls of the heating tube 9. Hot air blown out from the air outlets 8 can achieve hot air drying. The blowing air can also blow away water droplets on the optical film or blow them into smaller droplets. Since the water droplets are smaller, the drying time can be shortened. The staggered air outlets 8 can ensure that the hot air blown out is evenly blown onto the optical film, improving the uniformity and effectiveness of the hot air treatment.

[0018] A blower 2 is detachably connected to the side of the dryer 1 away from the discharge cylinder 3 and near both ends. The blower 2 has a fan blade 12 detachably connected to it via a motor. An electric heating plate 13 is fixedly connected to the inside of the blower 2 near the side wall of the dryer 1, and the electric heating plate 13 has holes. A flange is fixedly connected to the blower 2 near the outer edge of the dryer 1, and the blower 2 is detachably connected to the dryer 1 via the flange. An air duct 10 is provided inside the dryer 1 near the drying tank 14. Air outlet 8 is connected to air duct 10. The number of air ducts 10 is the same as the number of rows of air outlet 8. Air inlet 11 is opened on the side wall opposite to the blower 2 of the dryer 1. Air duct 10 is connected to air inlet 11. Air inlet 11 is connected to the inside of blower 2. The inner wall of air outlet 8 is inclined. Discharge cylinder 3 is L-shaped. The inside of discharge cylinder 3 is open. Steam outlet groove is opened through the side wall opposite to the dryer 1 and discharge cylinder 3. Discharge cylinder 3 is connected to drying tank 14 through steam outlet groove.

[0019] The technical effects of this solution are as follows: the steam outlet can send the water vapor generated during the drying process into the discharge cylinder 3 and discharge the water vapor along the discharge cylinder 3, avoiding the accumulation of water vapor in the drying tank 14 and affecting the drying effect. Because the air outlet 8 has an inclined structure, it can guide the hot air to blow towards the discharge cylinder 3, thereby ensuring that the blown airflow can smoothly clean the water droplets on the optical film. Activating the fan blades 12 can send the heat generated on the heating plate 13 into the air duct 10, and finally blow it onto the optical film through the air outlet 8.

[0020] Specifically, in use, one end of the optical film is inserted into the dryer 1 between two cleaning plates 4. The optical film is then conveyed by a rotating roller 7 driven by a motor. As the optical film moves, the cleaning plates 4 squeeze and clean the water droplets on the optical film, thereby reducing the volume of the water droplets and improving the efficiency of subsequent drying. The sponge pad 5 fixed on the cleaning plate 4 can absorb water, achieving the effect of preliminary drying. As the optical film moves, it first passes through the front hot air area. The fan blades 12 are pre-activated so that the air blown out carries the heat from the electric heating plate 13 into the air duct 10, and then is discharged through the air outlet 8. The hot air blown out performs preliminary drying on the optical film. Then, the optical film is dried a second time through the heating tube 9. Finally, the optical film passes through the rear hot air area, thus achieving a triple drying function, which can effectively improve the efficiency of drying.

[0021] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0022] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
