Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of film processing, concretely to a coating drying machine for film processing production. BACKGROUND

[0002] Film coating drying is the process of removing water or solvent in the film coating through heating and other ways, which makes the coating quickly solidify, dry and adhere to the substrate. This process can improve the adhesion and hardness of the coating, enhance its wear resistance, corrosion resistance and other properties, ensure the stability and reliability of the film coating in practical application, and is widely used in packaging, electronics, optics and other fields.

[0003] Under the existing technical conditions, the film coating drying process encounters a rather tricky problem. During the drying process of the film, due to the unscientific and unreasonable design of the internal structure of the device, the film inevitably comes into contact with the internal structure of the device. This contact is not just a slight touch, but during the drying process, as the film moves and the relative position of the internal structure of the device changes, friction and pulling will occur to some extent. However, the film coating itself is relatively fragile and cannot withstand such external forces. Under the continuous friction and pulling, the powdery substances attached to the surface of the coating will easily fall off from the coating, resulting in powder falling. Powder falling not only affects the appearance quality of the film coating, but also reduces its performance and service life. Therefore, we propose a coating drying machine for film processing production. SUMMARY

[0004] One of the technical problems to be solved by the present application is that during the drying process, as the film moves and the relative position of the internal structure of the device changes, friction and pulling will occur to some extent, resulting in powder falling.

[0005] To solve the above technical problems, the present application provides a coating drying machine for film processing production, which comprises a chassis and further comprises:

[0007] A drying unit is arranged in the box body, and the drying unit is provided with a first fan, a first air guide frame, a second fan and a second air guide frame. The first air guide frame and the second air guide frame are driven to descend synchronously, thereby pulling down the film and tightening the wrinkles. The drying unit is provided with an air port plate for drying the two sides of the film.

[0008] In some embodiments, the drying unit comprises a first pull-down piece arranged in the box body, a top of the first pull-down piece is provided with a second pull-down piece, the first pull-down piece and the second pull-down piece cooperate to pull down the film and tighten the wrinkles, and a drying piece is arranged in the box body to dry the two sides of the film.

[0009] In some embodiments, the first pull-down piece comprises a hydraulic rod arranged at the bottom of the chassis, a top end of the hydraulic rod is provided with a frame plate, a limiting rod is inserted in the frame plate, a top of the frame plate is provided with a first connecting plate, the first connecting plate is provided with a first motor, a driving end of the first motor is provided with a first fan, the first fan is rotationally connected in the first connecting plate, and a top of the first connecting plate is provided with a first air guide frame.

[0010] In some embodiments, the second pull-down piece comprises a support plate arranged at the top of the frame plate, a top of the support plate is provided with a second connecting plate, the second connecting plate is provided with a second motor, a driving end of the second motor is provided with a second fan, the second fan is rotationally connected in the second connecting plate, and a bottom of the second connecting plate is provided with a second air guide frame.

[0011] In some embodiments, the drying piece comprises an air port plate arranged on the inner side of the box body, an outer side of the air port plate is provided with an air pipe, the air port plate and the air pipe are arranged in multiple, a connecting pipe is arranged between the multiple air pipes, and an external connecting pipe is arranged outside the connecting pipe.

[0012] In some embodiments, the first pull-down piece and the second pull-down piece are vertically coaxially aligned, and the drying piece is arranged in two groups, and the two groups are opposite on the two sides of the box body.

[0013] In some embodiments, a guide assembly is arranged at the top of the chassis to guide the movement of the film by the first guide roller and the second guide roller.

[0014] In some embodiments, the guide assembly comprises two first guide rollers arranged at the top of the box body, an outer side of the box body is provided with an external connecting block, and a bottom of the external connecting block is provided with a second guide roller.

[0015] The utility model at least has the following beneficial effects:

[0016] 1. By setting two drying pieces, because two drying pieces are oppositely arranged, so the film arranged in the box body is limited in the middle position by the hot air on the two sides, does not contact with the inside of the box body, and the hot air on the two sides dries the two sides of the film, in addition, the film between the first air guide frame and the second air guide frame is also limited in the middle position, does not contact with other structures, so that the film can be dried, and the film can be prevented from contacting with other structures in the drying process, thereby causing powder dropping;

[0017] 2. By setting the first pull-down member and the second pull-down member, the bottom of the film is restricted by the first pull-down member and the second pull-down member, so as to pull the film down, thereby tightening the film and avoiding wrinkles. Attached Figure Description
