Utility Model Content

[0004] To overcome the shortcomings of existing technologies, an environmentally friendly drying device for plastic film is provided to solve the problems that existing drying devices cannot dry the upper and lower surfaces of the plastic film simultaneously, and the drying spacing cannot be adjusted, which affects the drying efficiency and makes them inefficient and impractical.

[0005] To achieve the above objectives, an environmentally friendly plastic film drying device is provided, comprising a top plate and an upper drying structure. An upper lead screw is fitted in the middle of the top plate, and the upper drying structure is movably connected to the upper lead screw. Side support plates are fixed to both ends of the top plate, and a lower fixing plate is fixed to the lower inner side of the side support plates. A lower lead screw is fitted in the middle of the lower fixing plate, and the lower drying structure is movably connected to the lower lead screw. A front support frame is installed on the left side of the upper end face of the lower fixing plate. A front bearing seat is provided on the upper part of the front support frame, and a plastic film unwinding roller is mounted on the upper part of the front bearing seat. A front mounting frame is provided on the upper right side of the front support frame. A first upper mounting plate and a first lower mounting plate are arranged parallel to each other on the upper part of the front mounting frame. Three sets of first upper conveyor wheels are fitted on the first upper mounting plate, and a... Three sets of first lower conveyor rollers are arranged, with the first upper conveyor roller and the first lower conveyor roller aligned vertically. The plastic film unwound from the plastic film unwinding roller passes between the first upper conveyor roller and the first lower conveyor roller from left to right. A rear support frame is installed on the right side of the upper end face of the lower fixed plate. A rear bearing seat is provided on the upper part of the rear support frame, and a plastic film take-up roller is mounted on the upper part of the rear bearing seat. A rear mounting frame is fixed on the left side of the upper end face of the rear support frame. A second upper mounting plate and a second lower mounting plate are arranged parallel to each other on the upper part of the rear mounting frame. Two sets of second upper conveyor rollers are fitted on the second upper mounting plate, and three sets of second lower conveyor rollers are fitted in the second lower mounting plate. The second upper conveyor roller and the second lower conveyor roller are aligned vertically. The plastic film passing between the second upper conveyor roller and the second lower conveyor roller is wound onto the plastic film take-up roller.

[0006] Furthermore, a first chain wheel is installed on the upper part of the upper lead screw, and an upper chain is drivenly connected to the first chain wheel. The upper end of a set of upper lead screws on the right front is installed at the front end of the first motor.

[0007] Furthermore, a second chain wheel is installed at the lower part of the lower lead screw, and a lower chain is driven and connected to the second chain wheel. The lower end of a set of lower lead screws on the right front is installed at the front end of the second motor.

[0008] Furthermore, the upper drying structure is equipped with a ventilation net, on which multiple sets of turbine fans are installed.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model utilizes a first motor to rotate the upper screw clockwise, which causes the upper drying structure to move straight up, while rotating it counterclockwise causes the upper drying structure to move straight down, facilitating flexible raising and lowering of the upper drying structure. Similarly, using a second motor to rotate the lower screw clockwise causes the lower drying structure to move straight down, while rotating it counterclockwise causes the lower drying structure to move straight up, facilitating flexible raising and lowering of the lower drying structure. This allows for easy control of the drying distance between the upper and lower drying structures and the upper and lower surfaces of the molding film.

[0012] 2. This utility model utilizes the heat-conducting pipe on the inner frame to conduct heat to a certain temperature. Then, when the turbine fan blows air downwards, it will drive the heat downwards, making it convenient to use hot air to dry the upper surface of the plastic film. Similarly, the lower drying structure can be used to dry the lower surface of the plastic film. Drying the upper and lower surfaces of the plastic film at the same time helps to speed up the drying process and make the drying faster and more uniform.

[0013] 3. The front support frame in this utility model not only facilitates the mounting of the plastic film unwinding roller, but also facilitates the use of the first upper conveyor wheel and the first lower conveyor wheel to guide the conveyed plastic film in a straight line.

[0014] 4. The rear support frame of this utility model not only facilitates the mounting of the plastic film take-up roller, but also facilitates accurate and stable guidance of the conveyed plastic film through the second upper conveyor wheel and the second lower conveyor wheel, making it more convenient and practical.
