Description

Multi-station ultrasonic spraying device and method

technical field

The invention relates to the field of liquid material coating, in particular to a multi-station ultrasonic spraying device and method, in particular to a multi-station high-speed automatic continuous double-sided ultrasonic spraying device and method.

Background technique

The coating of liquid materials usually adopts brush coating, roller coating, pressure ultrasonic spraying and so on. Ultrasonic atomization ultrasonic spraying uses high-frequency ultrasonic vibration energy to atomize liquid into tiny droplets, and the droplets reach the surface of the coated material by gravity or purge gas to realize the coating process. Since the amount of liquid in the ultrasonic spraying process is controllable and the droplet volume is small enough, the single coating amount is easy to control within the required range, so ultrasonic atomization ultrasonic spraying is often used in fields that require precise control of the coating amount. Compared with other coating equipment, ultrasonic atomization ultrasonic spraying has the following significant advantages: low energy consumption, high atomization efficiency, adjustable droplet diameter, and more reliable ultrasonic spraying quality.

However, due to the consideration of practical economy and processing difficulty, the power of a single ultrasonic nozzle should not be too large, and it is affected by the viscosity, surface tension, solid content, solution uniformity and other physical and chemical indicators of the liquid material. The ultrasonic atomization ability of the nozzle is often limited, so the final liquid material that can be processed by ultrasonic spraying has some limitations in terms of concentration and viscosity. Generally, the viscosity of the liquid material that can be processed is about 10cps, and the solid content generally should not exceed 40%. Therefore, , In order to achieve a higher thickness and weight of the sprayed material, multiple spraying is required, which requires the ultrasonic spraying head to reciprocate for multiple spraying operations, which takes a long time. Agglomeration, or even flow, requires that the coated material should not run too fast. In extreme cases, the coated material may need to be suspended in place to wait for drying, which eventually leads to slow continuous spraying and low efficiency. When there is an application requirement for double-sided spraying, the sheet can only be manually turned over after finishing one-side spraying, and then the second spraying is carried out. For coiled materials, one method is to spray on one side completely and roll it up, and then unroll it again to spray on the other side for a second time. Obviously, this method is less efficient. The second method is to use a vertical method to vertically transmit and pull the material to be coated in a vertical manner with the ground, and install ultrasonic spray heads on both sides of the material to be coated. It reciprocates in the direction of the moving direction of the coated material, so as to achieve double-sided spraying, but if the coating amount is too large or the drying is insufficient, there is a risk of droplets flowing, so the processing speed of this method will not be too fast.

To sum up, limited by factors such as spraying materials and ultrasonic nozzle power, traditional spraying devices generally have problems of slow speed and low efficiency. When used in continuous double-sided ultrasonic spraying, either the process is cumbersome and the efficiency is low, or the spraying device Size is subject to site height restrictions. The invention relates to a multi-station full double-sided ultrasonic spraying device and method, which can realize one-time double-sided ultrasonic spraying with a large coating amount, and the site has no height limit.

The patent document with the publication number of CN104624428B discloses a full-angle ultrasonic spraying operating system, the system includes: a workpiece clamping unit, the workpiece clamping unit is used for clamping the workpiece to be sprayed; an ultrasonic spraying unit, the The ultrasonic spraying unit is used for ultrasonic spraying of the workpiece to be sprayed; the negative pressure adsorption unit is used to control the air pressure inside the ultrasonic spraying operating system to maintain a negative pressure; the driving control unit is used for The workpiece clamping unit, the ultrasonic spraying unit and the negative pressure adsorption unit are driven and controlled. The invention realizes precise ultrasonic spraying, the particle size can reach the micrometer scale, and meanwhile, the uniformity and adhesion ability of the sprayed reagents are significantly improved. However, this solution cannot realize one-time double-sided spraying, and the size of parts to be processed in sequence is limited, there is no drying device, and the spraying efficiency is low.

Protect the sprayed surface; Step 5: The material covered with the protective film moves to the turning unit, and is turned over by the turning unit, so that the unsprayed side of the material faces the ultrasonic spraying unit of the second spraying module (300) and enters the second spraying module (300), and repeats steps 2 to 300. step 4; Step 6: The material that has been sprayed on both sides and covered with a protective film is wound up by a winding unit (400).
