[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The figure shows a thin film moisture drying device, including two L-shaped supports 1. The two L-shaped supports 1 are symmetrically arranged and a drying structure 2 is installed between them. The drying structure 2 includes a hot air duct 201 and an air guide plate 202. The air guide plate 202 is a hollow structure. Both ends of the air guide plate 202 are installed vertically with the L-shaped supports 1. The top of the air guide plate 202 is connected to two ducts 203. An air outlet channel 204 is opened on the front side wall of the air guide plate 202. The hot air duct 201 is located at the other end of the duct 203. The air outlet of the hot air duct 201 is connected to the duct 203. A filter structure 3 is installed at the air inlet.
[0019] It is worth noting that by installing the L-shaped bracket 1 at the outlet of the film drying equipment and turning on the hot air tube 201, the discharged film can be dried a second time without having to put the film back into the drying equipment for drying again. The added secondary drying can effectively remove water stains from the film surface, ensuring the quality of the film. The added structure is simple and low in cost, and it also eliminates the need for manual removal of water stains in local areas using an air gun, thus improving work efficiency.
[0020] Please see Figure 1 and Figure 3 The air guide plate 202 has a rotating shaft 205 fixedly connected to both ends. The rotating shaft 205 rotates through the vertical surface of the L-shaped bracket 1, and the through end is provided with a thread 207. The outer end of the rotating shaft 205 is threaded with a matching nut 206. The hot air generated by the hot air duct 201 enters the hollow structure of the air guide plate 202 through the duct 203, and is then evenly blown onto the film through the air outlet channel 204 to achieve rapid drying of the film. In order to adjust the air outlet angle of the air outlet channel 204, one end of the air guide plate 202 is rotatably connected to the vertical surface of the L-shaped bracket 1 through the rotating shaft 205, and the other end is fixed by the cooperation of the nut 206 and the thread 207. In this way, the tilt angle of the air guide plate 202 can be adjusted according to actual needs to achieve the best drying effect.
[0021] Please refer to Figure 1 The L-shaped bracket 1 has several mounting holes 101 on its horizontal surface. These mounting holes 101 are designed to facilitate the fixed installation of the L-shaped bracket 1 in the appropriate position of the drying equipment, ensuring the stability and accuracy of the entire drying assembly.
[0022] See Figure 1 , Figure 3 and Figure 4 The filter structure 3 includes a mesh cylinder 301 and a filter screen 305. The mesh cylinder 301 is sleeved and installed at the inlet end of the hot air duct 201. The filter screen 305 is installed inside the mesh cylinder 301. The filter structure 3 filters the air entering the hot air duct 201 to prevent dust and impurities from entering the hot air duct 201 and affecting the drying effect.
[0023] See Figure 2 and Figure 4 The top of the inner wall of the mesh cylinder 301 is fixedly connected with several annularly arranged compression springs 302. The outer wall of the inlet end of the hot air duct 201 is fixedly connected with two symmetrically arranged protrusions 303. The adjacent side walls of the mesh cylinder 301 are provided with two symmetrically arranged notches 306. The inner side wall of the mesh cylinder 301 is provided with an annular limiting groove 307. The notches 306 are connected to the annular limiting groove 307. The filter screen 305 is fitted with a gasket 304. The gasket 304 is fixedly connected to the other end of the compression spring 302.
[0024] When the screen cylinder 301 is installed at the inlet end of the hot air duct 201, the protrusion 303 will be engaged in the notch 306. The protrusion 303 moves to the position of the annular limiting groove 307. The screen cylinder 301 is rotated again. At this time, the washer 304 is subjected to the elastic force of the compression spring 302. The setting of the annular limiting groove 307 effectively prevents the washer 304 and the filter screen 305 from being displaced in the radial direction, ensuring that the filter screen 305 is always firmly installed at the inlet end of the hot air duct 201. This design not only facilitates the installation and disassembly of the filter screen 305, but also facilitates the cleaning or replacement of the filter screen 305, ensuring the continuous and efficient operation of the filter structure 3.
[0025] See Figure 2 The outer diameter of the hot air duct 201 is smaller than the inner diameter of the mesh tube 301, the outer diameter of the hot air duct 201 is larger than the inner diameter of the washer 304, and the outer diameter of the washer 304 is smaller than the inner diameter of the mesh tube 301. This ensures that the hot air duct 201 can properly squeeze the washer 304, thereby compressing the compression spring 302, thus forming tension and ensuring the firmness of the mesh tube 301 after installation.
[0026] Working principle: During use, the hot air duct 201 generates hot air, which enters the duct 203 through the air outlet, then is guided into the hollow structure of the air guide plate 202, and finally blows onto the film to be dried through the air outlet channel 204. Since both ends of the air guide plate 202 are rotatably connected to the vertical plane of the L-shaped bracket 1 via rotating shafts 205, and the outer end of the rotating shaft 205 is threaded with a matching nut 206, the angle of the air guide plate 202 can be adjusted according to actual needs, thereby changing the air outlet direction to adapt to the drying requirements of films of different thicknesses and materials.
[0027] Meanwhile, the filter structure 3 can effectively prevent dust and impurities from entering the hot air duct 201, ensuring the purity of the hot air.
