Waterproof paperboard surface film covering device and using method

Abstract

The invention relates to the technical field of paperboard processing, and discloses a waterproof paperboard surface film covering device which comprises a device box body, and a rotary film covering mechanism and a cooling and gluing mechanism are arranged in the device box body; the rotary film covering mechanism comprises a glue storage box, a square hole, a double-end motor, a first motor shaft, a first electric telescopic cylinder, a fixing rod, film barrels and a second electric telescopic cylinder. The double-end motor, the electric telescopic cylinders and the film barrels are arranged in the device box body, so that the two film barrels can be utilized to rotate, double-rotation film covering can be performed on a paperboard, multiple side edges of the paperboard can be directly covered with films, the film covering angle is increased, and the waterproof effect is improved; the electric telescopic cylinder are connected with the fixing rod, the distance between the film barrel and a paperboard can be freely adjusted, so that the paperboards of different sizes are coated with films, moreover, when the film barrel is rotated to the transverse direction, the film barrel is moved up and down, the coated film on the paperboard can be compacted, and the film covering mechanism and a compacting mechanism are combined together.

Description

technical field [0001] The invention relates to the technical field of cardboard processing, in particular to a water-proof cardboard surface coating device and a use method. Background technique [0002] Nowadays, cartons are the most widely used packaging products. There are various types of paper types. Cartons are commonly used with three layers and five layers. The goods will lose their protective effect, and the various text patterns on the surface of the damp cartons will also be affected. [0003] Patent No. CN201720591773.0 discloses a packaging cardboard surface coating device, including a cardboard conveyor, the outer wall of the upper end of the cardboard conveyor is fixedly connected with a cardboard placement box, and the cardboard placement box includes a protective panel and a cardboard placement box. cavity, the protective panel is fixedly connected to the upper outer wall of the inner cavity of the cardboard storage box, one side of the cardboard conveyor ...

AI Technical Summary

Problems solved by technology

[0004] However, the existing packaging cardboard surface coating device cannot directly rotate the film at multiple angles during the film coating process, and can only cover the front and back sides, but cannot cover the sides, resulting in the waterproof effect of the cardboard being affected. impact, and it is necessary to set up an additional compaction mechanism to compact the film, and it is impossible to combine the compaction mechanism with the film mechanism. Glue is heated to increase fluidity
