Adjustable tuyere structure

Abstract

The invention discloses an adjustable tuyere structure. The adjustable tuyere structure comprises a tuyere body, wherein an air inlet of the tuyere body is upwards formed and movably connected with an air box with an opening in the bottom in a sleeved manner, an angle adjusting mechanism is connected between the air box and the tuyere body, and the front portion of an air outlet of the tuyere body is movably connected with a tuyere cover in a sleeved manner; and a length adjusting mechanism is arranged between the tuyere cover and the tuyere body. According to the adjustable tuyere structure, the problem that because the blowing angle of the tuyere relative to a material film cannot be adjusted, the heat exchange efficiency is low is solved through the angle adjusting mechanism; and through the length adjusting mechanism, the problem that because the distance between an air outlet of the tuyere and the material film cannot be adjusted, tension lines are liable to be generated on the surface of the material film is solved, the heat exchange efficiency is improved on the premise that the hot air volume and the air speed are guaranteed, and then the tuyere structure can adapt to different processes on the premise that the product quality is guaranteed, the production efficiency is improved and the equipment cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of coating and drying equipment, and in particular relates to an adjustable tuyere structure. Background technique [0002] The air nozzle structure equipped with existing equipment in the precision coating industry can only work at a fixed height and a fixed angle above the material film, which has low heat utilization rate, single applicable process, and slow drying speed, which is easy to form tension on the surface of the material film In the drying stage, the heat exchange cannot be performed quickly and with high quality, so the length of the oven must be increased to achieve the purpose, and an excessively long drying tunnel will inevitably increase the production site and design costs. Contents of the invention [0003] The purpose of the present invention is to provide an adjustable tuyere structure, the distance and angle between the air outlet and the material film can be adjusted as required, s...
