Embodiment Construction
[0015] A horizontal rotary screen high-temperature oven, as shown in Figure 1, includes a box body 1, the box body 1 is an airtight heat preservation box body, and the upper part of the box body is provided with an air outlet valve 10, when the air pressure in the box body 1 is greater than the set value , the outlet valve 10 is automatically opened to keep the air pressure in the casing 1 constant. Casing 1 is provided with the box door 3 that can take and put cylinder net, and box door 3 is hinged on the top of box body 1, is provided with the cylinder 2 that can make box door 3 open and close between this box door 3 and box body 1. The inside of the box body 1 is provided with a rotatable support that can place ten cylinders (not limited to ten) horizontally. The support body includes a rotating shaft 6, the two ends of the rotating shaft 6 are respectively fixed with left and right support discs 7a, 7b, and the left and right support discs 7a, 7b are respectively provided ...

The invention discloses a horizontal circular netlike high temperature bake oven, it settles the problem that circular net is easy to dip when it is roasted and affect the quality when it is heated non-uniform. The essential of the invention as follows, put some circular netlike backstops in the bosom which can be deposited flatly and can be run, and these backstops are driven by power system. The air in the bake oven can be carried from the bottom of the art to the opposite and the top, and form the channel of sirocco. The fan related to is fixed at the unilateral bottom, the air outlet is connected with the channel of sirocco. The heating system is an immersion heater, and it is settled in the channel which near the air outlet. The invention can be handled easily, the circular net do not dip when it is roasted. At the same time, the temperature difference is small, the air circulate fast, so the quality and the speed of the net are heightened by a long way.
Description
technical field [0001] The invention relates to the technical field of printing and dyeing machinery, in particular to a high-temperature oven used for melting and drying the developed printing machine cylinder screen to cure photosensitive glue. Background technique [0002] The rotary screen is the key component of the printing machine. The production of the rotary screen includes two main steps: first, the pattern information is developed on the rotary screen photosensitive adhesive; then the developed rotary screen is baked and dried in a high-temperature oven, generally at 150°-180°, to cure the photosensitive adhesive , in preparation for printing. The known high-temperature rotary screen oven has a vertical structure. The rotary screen of the printing machine is placed on the bottom plate of the oven and is not fixed. During the baking and drying process, due to the hot air circulation and convection, the rotary screen tends to fall. Secondly, due to the dead angle ...
