Circular-drying case body of coating machine, drying device and drying assembly line

Abstract

The invention provides a circular-drying case body of a coating machine, a drying device and a drying assembly line; the circular-drying case body of the coating machine uses an independent inner air chamber; a circular air returning inlet is separated from an air exhaust outlet; a multi-point air discharging method is used so as to process independent control; the drying device is provided with an independent circular blower and an air exhaust blower; a whole guiding and shunting device is designed reasonably according to basic knowledge of fluidics; thus, each air nozzle in the case body has uniform air blowing quantity; pressure is balanced; drying uniformity is improved; therefore, each point of a product is dried synchronously so as to increase drying efficiency.

Description

technical field [0001] The invention relates to a coating supporting device, in particular to a coating machine circulation drying box and a drying device. Background technique [0002] The coating process is widely used in new energy batteries, solar cells, optical films, flexible circuit boards and other industries, and it is also a key process that directly affects product quality. Coating is the process of coating the prepared paste-like viscous slurry evenly, continuously or intermittently on the front and back sides of the substrate (aluminum foil or copper foil), and then drying. The drying effect directly affects The precision of coated products and drying efficiency also directly affect the production efficiency of equipment. [0003] Most of the existing coatings are simple circulation drying devices, such as Figure 1-3 As shown, an air inlet chamber 200 is formed at the upper and lower intervals inside the oven main body 100, and an air outlet 600 is provided.

Problems solved by technology

[0003] Most of the existing coatings are simple circulation drying devices, such as Figure 1-3 As shown, an air inlet chamber 200 is formed at the upper and lower intervals inside the oven main body 100, and an air outlet 600 is provided. Between the two air inlet chambers 200 is a drying chamber 400, and the air inlet chamber 200 faces the drying The chamber 400 is provided with an air nozzle 300, and the air inlet chamber 200 is provided with an air inlet pipe 500. The circulation air outlet under the main body 100 of the oven draws out the air through the heater 900 and then returns to the air inlet pipe 500 to form recycling. However, due to its circulation pipe The outlet and the flow channel are shared by the air duct and the exhaust pipe, and the design is unreasonable, resulting in poor circulation, uncontrollable intersection of circulation volume and exhaust air volume, and it is difficult to save energy; in addition, its air inlet directly faces the substrate (painted Cloth products), there is no effective guiding and diverting device, resulting in uneven drying of the product, cracking and curling due to local over-drying, and low drying efficiency; due to poor ventilation, it is easy to cause the concentration of solvent gas inside the box to be too high , leading to equipment alarm shutdown or even fire and explosion
