The placement box has a mesh-like perforated design, and the interior of the placement box is provided with positioning mechanisms symmetrically distributed on the left and right for pressing the plastic film.

[0007] A curing component, mounted on a housing, includes an air pump fixedly installed on the top of the housing. A heating box is fixedly connected to the top of the housing. Electric heating wires are evenly distributed between the inner walls of the heating box. The output end of the air pump is located inside the heating box. A gas distribution pipe is provided on one side of the heating box. The gas distribution pipe is located inside the housing. Evenly distributed nozzles are provided on the gas distribution pipe. A pressure relief valve is provided on one side of the housing.

[0008] Furthermore, the input end of the air pump is threadedly connected to a filter box, a filter plate is fixedly connected between the inner walls of the filter box, and a temperature sensor is provided on the inner wall of the heating box.

[0009] Furthermore, the positioning mechanism includes a movable rod hinged to the placement box, the lower end of the movable rod is connected to a pressure plate via a universal joint, a slider slides on the movable rod, a sliding column is hinged to the bottom wall of the slider, the lower end of the sliding column vertically penetrates the placement box and slides therewith, a spring is sleeved on the sliding column, and its two ends are fixedly connected to the placement box and the sliding column.

[0010] Furthermore, an electric push rod is fixedly installed at the bottom of the placement box, and a connecting plate is fixedly connected to the free end of the electric push rod. Sloping plates are fixedly connected to the top of both ends of the connecting plate.

[0011] Furthermore, the lower end of the sliding column is provided with a ball bearing, which is in contact with the outer wall of the inclined plate.

[0014] (1) By placing the symmetrical positioning mechanism inside the box, combined with the cooperation of the movable rod, slider, sliding column, spring and other components, the plastic film can be stably clamped. The electric push rod drives the connecting plate and the inclined plate to move, which drives the sliding column to move up and down, so as to realize the automatic pressing and releasing of the plastic film by the pressure plate, which avoids the plastic film from shifting and wrinkling during the curing process, ensuring the uniformity of the curing effect, and does not require manual adjustment, making the operation convenient.

[0015] (2) The air pump sends outside air into the heating box after filtering it through the filter plate. The electric heating wire heats the air. The hot air is evenly sent into the box through the evenly distributed nozzles on the air distribution pipe, so that the plastic film is heated evenly in all parts, reducing the situation of local over- or under-curing, and improving the stability of product quality. The temperature sensor can monitor the temperature inside the heating box in real time, which is convenient for precise control of the heating process.

[0016] (3) The rotating shaft is driven by gear one and gear two, which causes the placement box and plastic film to rotate, further improving the uniformity of contact between hot air and plastic film and enhancing the curing effect. The pressure relief valve on the box can balance the air pressure inside the box and ensure the safe operation of the device. Attached Figure Description
