Description

Plastic film drying machine

Technical Field

The utility model relates to the technical field of drying machines, in particular to a plastic film drying machine.

Background Art

Plastic film is a new type of decorative material made of high molecular polymer as raw material, adding various additives, calendering and compounding. It can be compounded with wood, plastic board, aluminum plate, iron plate and other base materials to make multi-purpose decorative materials. It is widely used in household appliances, audio surface decoration, interior decoration, aircraft, ships, train interior decoration. At present, plastic film needs to be dried during the processing, and usually a special drying device for plastic film is used for the operation.

The prior art, for example, is a plastic film drying machine with application number CN202222392569.X, which includes a drying machine body, two supporting legs fixedly installed at the bottom of the drying machine body, a feed port opened on the left side of the drying machine body, a discharge port opened on the right side of the drying machine body, a connecting block fixedly installed on the right side of the drying machine body, a receiving roller for winding the film fixedly installed on the connecting block, a driving motor for driving the receiving roller to rotate fixedly installed on one side wall of the connecting block, and two drying components symmetrically arranged inside the drying machine body. In the utility model, the high-temperature gas is then discharged through the hot air outlet inside the drying card slot to dry the film. Since the film is squeezed into an S shape by the two drying components at this time, its heat contact surface is greatly increased, and the multiple hot air outlets opened on the drying card slot can form an effective convection effect, thereby greatly improving the drying efficiency of the plastic film.

However, during the drying process, the dried air will be directly discharged into the external environment without reusing the waste heat, thereby increasing energy consumption and raising drying costs.

Then the operator controls the hydraulic rod 5 to work, so as to facilitate driving the drying block 4 close to the plastic film. Then the operator controls the winding roller 3 to rotate synchronously, so as to facilitate driving the plastic film to move. At the same time, the operator controls the fan 7 and the heating box 6 to work, so as to facilitate blowing hot air to the surface of the plastic film through the drying cavity and the drying port, so as to facilitate drying the plastic film.

The disassembly device includes a first fixed disk 8, a second fixed disk 9, a rotating motor 10, a support column 11, a support ring 12 and a support plate 13. The first fixed disk 8 is rotatably arranged on the front side wall of the support block 2 located at the rear side of the feed port, and a first fixed groove is arranged on the front side wall of the first fixed disk 8. The rotating motor 10 is arranged on the rear side wall of the support block 2 located at the rear side of the feed port, and the output end of the rotating motor 10 is connected to the first fixed disk 8.
