Overview
The Rjy-04/250dc immersion crystallization Coater is a roll-to-roll continuous Spreader for substrate crystallization or adhesion treatment through a solution pool under specific conditions. The equipment adopts the immersion Spreader process and is equipped with a hot air oven for drying. The effective Spreader width can reach a maximum of 250mm.
Features
1. Adopt substrate tension control to stabilize the belt.
2. The main drive adopts servo drive, and the speed can be set.
3. The solution pool can be lifted and lowered, making it easy to operate through the tape.
4. The solution tank is designed with heating and separation of inner and outer layers, which is safe and reliable.
5. Equipped with hot air oven for drying.
6. Adopt PLC control and HMI man-machine interface for easy operation.
Principle
The device adjusts the tension by controlling the torque of the discharge spool and the reel, and uses the linear speed of the main drive roller as the main driving speed to realize the belt control. The substrate continuously travels through the solution pool in a roll-to-roll manner, and can be carried out at a fixed speed or at a fixed distance. The solution pool can be heated at a set temperature, and the lifting height can be adjusted. The drying oven uses electric heating air, and uses hot air to heat and dry the substrate after the Spreader.
Applications
It is suitable for the Spreader process where substrates are crystallized or adhered by solution under specific conditions.
Steps
1. Prepare the required substrate and solution.
2. Ensure that utilities (power, gas, environment, etc.) meet equipment requirements.
3. Set the process parameters such as belt speed, solution pool temperature and lifting height, drying temperature and so on through the HMI man-machine interface.
4. Carry out the tape threading operation, and use the lifting function of the solution pool to facilitate the tape threading.
5. Start the equipment, carry out the forward automatic belt, complete the dip coating, extrusion water removal (air knife water removal), Spreader, drying, rinsing, winding and other processes.
6. Monitor the operating status of the equipment to ensure that the tension is stable and the temperature is up to standard.
Notice
* The customer needs to prepare the required utilities before installation: single-phase 220V +/- 10%/50Hz power supply (power 9.5KW), 0.5-0 MPa compressed air source, Ambient Temperature 25 +/- 3 ℃, environment humidity 30~ 90% RH or lower, cleanliness level 1,000,000, no obvious vibration and explosion sources around, and ensure that there are enough handling channels and tools.
* Substrate requirements: maximum width 180mm, maximum roll diameter 250mm, maximum weight 50KG. The new material substrate is subject to the actual belt effect.
* Solution requirements: It cannot chemically react with the stainless steel material of the solution pool. The new material is subject to the actual effect.
The device correction function may not work at low speeds.
* When operating, pay attention to the high temperature of the heating part of the equipment (solution pool, oven) to prevent burns.
Regularly check and replace wearing parts, such as aluminum foil ducts, heating pipes, etc.
