Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] A heat setting oven for material film, such as figure 1 As shown, the box body 1 is included, and the box body 1 is provided with an upper air bladder 5 and a lower air bladder 2, the upper air bladder 5 is located at the top of the box body 1, and the lower air bladder 2 is located at the bottom of the box body 1; , and the lower inlet air bladder 2 is provided with a plurality of first guide roller devices 3, and the plurality of first guide roller devices 3 are arranged in a staggered upper and lower layers, and the material film is wound around the upper and lower layers of the first guide in the box body 1. The roller device 3 takes the material in a serpentine shape. Between two adjacent first guide roller devices 3, a mesh air nozzle 6 of a mesh air uniform plate is arranged. The air nozzle 6 on the top of the box body 1 is fix...

Abstract

The invention discloses a heat setting baking box for a material film. An inlet and an outlet are formed in the two sides of a box body respectively, the heat setting baking box comprises the box body, an upper-layer air container and a lower air inlet container are arranged in the box body, a plurality of first guide roller devices are arranged between the upper-layer air container and the lower air inlet container, and the first guide roller devices are arranged in an upper-layer and lower-layer staggered mode; an air nozzle is arranged between every two adjacent first guide roller devices and is fixed to the upper-layer air container or the lower air inlet container; air return containers are arranged on the two sides of the box body respectively, and the inlet and the outlet are located below the air return containers. The retention time of the material film can be prolonged, a drying tunnel can be shortened, and tension lines and wrinkles caused by high-temperature thermal deformation of the material film in the drying tunnel are avoided.

Description

technical field [0001] The invention belongs to the technical field of coating and drying devices, and relates to a heat-setting oven for material films. Background technique [0002] The oven unit equipped with existing equipment in the precision coating industry can only bake at a constant temperature within the length of the box. It has too long a drying channel, low heat utilization rate, short stay of the material film in the box, and easy thermal stress. Cause tension lines and other shortcomings, and the high-temperature curing stage requires a long residence time of the material film in the box, and an excessively long drying tunnel will inevitably increase the production site and design costs. Contents of the invention [0003] The object of the present invention is to provide a heat-setting oven for film, which solves the problems of short residence time of film and long drying tunnel in the prior art. [0004] The technical scheme adopted in the present inventi...
