[0002] PVC film is a thin film material made by special technology. Its main component is polyvinyl chloride. Through nano-filling technology, heat-insulating nano-materials can be added to PVC, so that the PVC film has good heat absorption and heat insulation effects. At the same time, it also has good transparency and can maintain a clear field of vision. The transparent heat-absorbing and heat-insulating PVC protective film has a long service life, is not easy to fade, has stable heat insulation performance, and has good weather resistance and anti-aging performance.

[0003] During the processing of PVC film, the PVC film needs to be dried. At present, most of the drying methods for PVC film are to directly pass the PVC film horizontally through the drying box. Although this can complete the drying of both sides of the PVC film, the distance the PVC film moves in the drying box is too short. Therefore, in order to ensure the drying effect, the PVC film is slowly transmitted in the drying box, which leads to low drying efficiency of the PVC film. Utility Model Content

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0028] like Figure 1-4 As shown, a double-sided drying device for PVC film processing of the utility model comprises a box body 1, an air supply box 11 is provided on the upper side of the box body 1, through grooves 12 are respectively provided on the left and right sides of the box body 1, an opening 13 connected to the two through grooves 12 is provided on the side wall of the box body 1, a cover plate 14 is provided, a sliding mechanism and a limiting mechanism are provided between the cover plate 14 and the box body 1, a plurality of transmission rollers 15 are provided on the upper and lower sides of the cover plate 14, a plurality of transmission rollers 15 on the same side are uniformly arranged in an array from left to right, a plurality of transmission rollers 15 on the upper and lower sides are alternately arranged, a plurality of transmission rollers 15 on the upper and lower sides are provided with an air storage frame 2 on one side facing the center of the box body 1, a plurality of air storage frames 2 are provided with cavities 21 inside, a plurality of air storage frames 2 are provided with through holes 22 connected to the cavity 21 on the outer walls on the left and right sides of the air storage frame 2, a plurality of air storage frames 2 are provided with air inlet pipes 23 connected to the cavity 21, a plurality of air inlet pipes 23 extend out of the box body 1 and are jointly equipped with an air supply pipe 24 connected to the air outlet of the air supply box 11.

[0029] When the PVC film needs to be dried, the staff can cancel the limit of the cover plate 14 through the limit mechanism. At this time, the cover plate 14 can be slid to move the cover plate 14 to the side away from the box body 1. The cover plate 14 slides relative to the box body 1 through the sliding mechanism. During the sliding process, the cover plate 14 drives the plurality of transmission rollers 15 to move out of the box body 1 until the plurality of transmission rollers 15 are completely moved out of the box body 1. At this time, the staff can alternately pass the end of the PVC film through the upper and lower transmission rollers 15 in turn to keep the PVC film in a folded state up and down. After the PVC film passes through the plurality of transmission rollers 15 up and down in turn, the cover plate 14 is moved again. Move into the box body 1, thereby driving a number of transmission rollers 15 and PVC films to move into the box body 1, and the two ends of the PVC film are respectively matched with the two through grooves 12, ensuring that after the cover plate 14 buckles the opening 13, the number of transmission rollers 15 are all located in the box body 1, and the two ends of the PVC film are respectively located in the two through grooves 12, when the PVC film moves into the box body 1 following the transmission rollers 15, the number of gas storage frames 2 are respectively located in the gaps of the folded PVC films, so that the surfaces of both sides of the number of gas storage frames 2 have PVC films, and such a design makes it easy for the staff to install the PVC films on the outer surfaces of the number of transmission rollers 15;

[0030] After the cover plate 14 closes the opening 13, the air supply box 11 can be started to start working, and the hot air is supplied into the air inlet pipe 23, and then the hot air enters the plurality of air supply pipes 24 respectively. The hot air enters the cavities 21 in the plurality of air storage frames 2 through the plurality of air supply pipes 24 respectively, and is ejected outward through the plurality of through holes 22 on the left and right sides of the air storage frame 2. Since each air storage frame 2 has a PVC film on both sides, the surfaces of both sides of the PVC film can be dried after the plurality of through holes 22 are ejected outward. Such a design can dry the surfaces of both sides of the PVC film, and when the PVC film is in the process of transmission, the entire PVC film can pass through the box body 1, so the PVC film can be dried as a whole.

[0031] The sliding mechanism includes four sliding components, which are grouped in pairs and are respectively divided into left and right sides of the box body 1. The two sliding components on the same side are symmetrically distributed up and down. The sliding component includes a mounting bar 3 connected to the box body 1. The mounting bar 3 is provided with a sliding hole 31. A sliding rod 32 is slidably assembled in the sliding hole 31. The sliding rod 32 extends out of the sliding hole 31 and is connected to a fixed block 33. The fixed block 33 is fixedly connected to the cover plate 14.

[0032] When the cover plate 14 is sliding, since the slide rod 32 is fixedly connected to the cover plate 14, the cover plate 14 slides in the slide hole 31 through the slide rod 32. When the four slide rods 32 slide in the slide hole 31, the sliding stability of the cover plate 14 can be improved.

[0033] A limiting hole 34 connected to the sliding hole 31 is provided in the mounting strip 3 . The diameter of the limiting hole 34 is larger than that of the sliding hole 31 . The end of the sliding rod 32 extends into the limiting hole 34 to be assembled with a limiting block 35 .

[0034] When the slide rod 32 slides, the slide rod 32 drives the limit block 35 to slide in the limit hole 34, and the inner wall of the limit hole 34 can limit the movement distance of the limit block 35, thereby preventing the slide rod 32 from moving out of the slide hole 31, thereby preventing the cover plate 14 from separating from the box body 1.

[0035] The limiting mechanism includes magnetic locking grooves 4 arranged on the left and right sides of the opening 13 , and magnetic locking blocks 41 matching the magnetic locking grooves 4 are arranged on the left and right sides of the cover plate 14 .

[0036] When the cover 14 is buckled with the box body 1, the cover 14 closes the opening 13. At this time, the magnetic lock block 41 is located in the magnetic lock slot 4. Since the magnetic lock block 41 is adsorbed in the magnetic lock slot 4, the cover 14 is limited to prevent the cover 14 from easily sliding and separating from the opening 13. When it is necessary to slide the cover 4 to open the opening 13, the staff can slide the cover 14 forcefully to overcome the suction force between the magnetic lock block 41 and the magnetic lock slot 4 until the magnetic lock block 41 is separated from the magnetic lock slot 4.

[0037] A sealing strip is provided on the inner wall of the cover plate 14 facing the inside of the box body 1. The design of the sealing strip can improve the sealing effect between the cover plate 14 and the opening 13.

[0038] The outer surface of the cover plate 14 is provided with a handle 42. The design of the handle 42 can facilitate the staff to slide the cover plate 14.

[0039] A plurality of transmission rollers 15 are detachably fixedly connected to the cover plate 14. Such a design facilitates the staff to inspect and maintain the transmission rollers 15.

[0040] A drain pipe 43 is provided at the bottom of the box body 1, and the bottom of the box body 1 is inclined from high to low from a side away from the drain pipe 43 to a side close to the drain pipe 43. If there is residual water at the bottom of the box body 1, the residual water at the bottom of the box body 1 can flow out through the drain pipe 43.

[0041] An exhaust pipe 44 is disposed on the upper side of the housing 1. Due to the design of the exhaust pipe 44, the gas in the housing 1 can be ejected outward from the exhaust pipe 44.

[0042] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
