Photocuring coating machine production line

Abstract

The invention discloses a photocuring coating machine production line. The photocuring coating machine production line sequentially comprises a material unwinding unit, a coating mechanism, a UV curing oven and a finished product winding unit according to the process sequence. The coating mechanism comprises a machine table, a conveying device, a pressing device, a gluing device and a drying device, wherein the conveying device, the pressing device, the gluing device and the drying device are arranged on the machine table. The pressing device comprises a driving wheel, a driven wheel, a pressing belt, a second driving unit and a lifting pressing mechanism. The UV curing oven comprises a supporting frame, a first oven body installed on the supporting frame and a UV lamp tube arranged in the first oven body. The UV lamp tube is arranged towards a second conveying belt. The UV lamp tube is connected with a moving mechanism used for driving the UV lamp tube to move in the extending direction of the second conveying belt, and the moving mechanism is connected to the first oven body. Therefore, different degrees of pressing can be conducted according to films with different thicknesses, the photocuring coating machine production line can be suitable for machining the films with different thicknesses, movable design of the UV lamp tube is achieved, and therefore the UV lamp tube can move in a reciprocating manner, and the baking temperature is more uniform.

Description

technical field [0001] The invention relates to the technology in the field of coating machines, in particular to a light-curing coating machine production line. Background technique [0002] The coating machine is mainly used for the surface coating process production of film, paper, etc. This machine is to coat the rolled substrate with a layer of glue, paint or ink with specific functions, and then wind it up after drying. It adopts a special multi-functional coating head, which can realize various forms of surface coating production. The winding and unwinding of the coating machine is equipped with a full-speed automatic film splicing mechanism, and the PLC program tension closed-loop automatic control. In the production process of the coating machine, due to the different thicknesses of different films, it is necessary to make adaptive adjustments to the films of different thicknesses. However, the adjustment of the coating mechanism in the prior art is relatively cumbe...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention aims at the deficiencies in the prior art, and its main purpose is to provide a light-curing coating machine production line, which solves the problem that the existing coating machine cannot adapt to the film of different thickness and compact The contact area is small, and the quality and effect of pressing cannot be guaranteed. The lamp tube of the oven is usually fixed on the inner top wall of the oven, and cannot be adjusted according to the size and position of the workpiece, resulting in high temperature near the lamp tube and high temperature at the place far away from the lamp tube. The low temperature makes the baking temperature uneven, which is not conducive to oven baking and affects product yield and other issues.
