Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.

In this application, unless expressly stated or limited otherwise, the terms "connected" and "fixed" are to be construed broadly, e.g., as meaning either a fixed connection or a removable connection, or an integral part; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the description of the present application, it is to be understood that the terms "longitudinal," "lateral," "horizontal," "top," "bottom," "upper," "lower," "inner" and "outer" and the like refer to orientations and positional relationships illustrated in the drawings, which are used for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the referenced devices or components must have a particular orientation, be constructed and operated in a particular orientation, and thus are not to be considered limiting.

Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

As shown in fig. 1 to 4, the present invention provides a drying device for a protective film, which comprises a machine body 10, a distributor 20, a vacuum pump 30 and a hot air blower 40. The distributor 20 is installed inside the body 10 in a lateral direction. The distributor 20 includes a pipe body 21, a first nozzle 22 and a second nozzle 23. The first nozzles 22 are provided with two, the two first nozzles 22 are respectively arranged at two ends of the tube body 21, the first nozzles 22 are communicated with the inside of the tube body 21, and the air outlets are inclined downwards along a direction close to the middle of the tube body 21. The second nozzles 23 are provided with a plurality of second nozzles 23 which are arranged on the tube body 21 at intervals and located between the two first nozzles 22, the second nozzles 23 are communicated with the inside of the tube body 21 through a connecting pipe 24, and the air outlets face vertically downwards.

When the drying device is operated, hot air enters the pipe body 21 and is sprayed to the surface of the plate 71 through the first nozzle 22 and the second nozzle 23. And because the air outlets of the first nozzles 22 at the two ends of the tube body 21 are inclined inwards, most of the hot air sprayed by the first nozzles is located in the middle of the machine body 10, so that the heat loss is reduced.

The air inlet of the vacuum pump 30 is communicated with the inside of the machine body 10, the air outlet of the vacuum pump 30 is communicated with the air inlet of the hot air blower 40, and the air outlet of the hot air blower 40 is communicated with the inside of the pipe body 21. Most of the hot air sprayed from the first nozzle 22 and the second nozzle 23 will remain in the machine body 10, and at this time, the vacuum pump 30 and the hot air blower 40 are turned on, so that most of the remaining hot air will be pumped by the vacuum pump 30, and will return to the distributor 20 for recycling after being reheated by the hot air blower 40, and finally be sprayed out from the first nozzle 22 and the second nozzle 23 again, thereby effectively recovering the heat energy and further reducing the loss of the heat energy.

In one embodiment, the first nozzle 22 communicates with the interior of the tube 21 through a hose 25. A rotating shaft 26 arranged along the transverse direction is fixedly installed on the outer wall of the first nozzle 22, and the rotating shaft 26 is rotatably connected with the pipe body 21. One end of the rotating shaft 26 passes through the supporting plate of the tube body 21 and then extends outward, and a rotating disc 27 is fixedly mounted on the end of the rotating shaft 26.

The outer circumferential surface of the rotating disc 27 is provided with a plurality of locking holes 271 arranged at intervals in the circumferential direction. A locking assembly 50 is also provided above the rotatable disc 27. The locking assembly 50 includes a fixing block 51 and a screw 52, the fixing block 51 is fixedly connected with the pipe 21, and a through threaded hole 511 is formed in the fixing block 51. The screw 52 is disposed in the threaded hole 511, and a threaded end of the screw 52 can pass through the threaded hole 511 and then extend into one of the locking holes 271.

When it is necessary to adjust the inclination angle of the first nozzle 22, the worker rotates the screw 52 away from the screw hole 511. The rotating disc 27 is then rotated to rotate the first nozzle 22 into position. Finally, the screw 52 is rotated again to make the threaded end enter the corresponding threaded hole 511. The inclination angle of the first nozzle 22 can be adjusted as required, so that more use requirements of workers can be met.

In one embodiment, a plastic film 11 is disposed between the machine body 10 and the roller conveyor 70, and the plastic film 11 is fixedly connected to the machine body 10 and contacts the roller conveyor 70. The existence of the plastic film 11 can shield the gap between the machine body 10 and the roller conveyor 70, and further reduce the dissipation of heat energy.

In one embodiment, a lift assembly 60 is also included. The lifting assembly 60 includes a guide rail 61 and a cylinder 62, and the guide rail 61 is fixedly disposed on the inner wall of the machine body 10 in the longitudinal direction. The pipe body 21 is connected with the guide rail 61 in a sliding mode, the air cylinder 62 is arranged along the longitudinal direction, the lower end of the air cylinder 62 is fixedly connected with the pipe body 21, and the upper end of the air cylinder 62 is fixedly connected with the inner wall of the machine body 10. When the air cylinder 62 works, the height of the distributor 20 can be changed, so that the distance between the first nozzle 22 and the second nozzle 23 and the plate 71 is changed, the drying effect is adjusted, and more use requirements of workers are met.
