Rotating mechanism and rotating plate baking machine thereof

Abstract

The invention discloses a rotating mechanism and a rotating plate baking machine thereof. The rotating mechanism comprises a rotating shell, a heating cavity is arranged in the rotating shell, and a plurality of through flow guide holes are formed in the rotating shell; a plurality of supports are arranged in the heating cavity and used for fixing a printing plate; a rotating big tooth is fixed onthe rotating shell and is in meshing transmission with rotating small teeth arranged on a first shaft body, second shaft bodies and a third shaft body respectively; one end of the first shaft body penetrates through a rear panel and is fixedly assembled with an output shaft of a rotating motor; the first shaft body, the second shaft bodies and the third shaft body are uniformly distributed in thecircumferential direction of the rotating big teeth by taking the axis of the rotating big teeth as the center; and the two second shaft bodies pass through the rear panel and are respectively assembled and fixed with a brake cylinder. The printing plate can rotate, so that the printing plate integrates two modes of a vertical mode and a horizontal mode, and can rotate in the baking process, andthe printing plate can be baked at any angle.

Description

technical field [0001] The invention relates to a hot plate machine, in particular to a rotating mechanism and a rotary hot plate machine. Background technique [0002] The baking machine is mainly used to bake the plate in the printing plate making process, so as to improve the printing durability of the printing plate. At present, there are mainly two types of baking machines, one is to hang the printing plate (vertical type) and then bake; the other is to lay the printing plate flat (horizontal type) and then bake. These two methods are mainly selected for different materials and processes, and each has its own advantages and disadvantages. However, both of these two devices have a disadvantage, that is, the temperature on the printing plate is prone to be inconsistent during the multi-layer simultaneous baking process, which will lead to an increase in the final reject rate and unstable product quality. Moreover, the horizontal type and the vertical type need to be pre...

Problems solved by technology

However, both of these two devices have a disadvantage, that is, the temperature on the printing plate is prone to be inconsistent during the multi-layer simultaneous baking process, which will lead to an increase in the final reject rate and unstable product quality.

Moreover, it is necessary to prepare the horizontal type and the vertical type according to different processes at the same time, and the cost and maintenance of the equipment are also relatively large.

At the same time, the waste gas after baking is generally discharged directly. This waste gas also contains a small amount of VOC components. Direct discharge will cause air pollution. As environmental protection requirements become more and more stringent, it is obvious that this method will be severely punished.
