Overview
JTM-300 small continuous Coater is a high Accuracy modular Spreader experimental equipment of HuiNuo brand. It adopts continuous coating method and is specially designed for hot-melt adhesive Spreader proofing or small production. The equipment can directly Spreader the hot-melt Pressure sensitive adhesive on the heat-resistant substrate or release paper, and supports film transfer and bonding. The whole machine is fully electric control without gas source, and is equipped with an electronically controlled precision tension system to adapt to paper, plastic, metal film, aluminum foil and other materials.
Features
1. High Accuracy Modular Spreader Station Structure, Modular Assembly
2. Fully electric control, no air source required
3. Dial meter indexing head precise fine-tuning Spreader gap control thickness
4. The minimum gluing thickness is 0.01mm, and the electric push rod provides downforce to prevent the gap from changing
5. Maximum Spreader width 300mm (effective width 280mm), unlimited length Spreader can be automatically rewound
6. Positive and reverse stepless speed change, Spreader speed 2-4.5 m/min adjustable, precision electronically controlled discharge tension
7. Quick-release glue tank, easy to remove residual glue
Principle
The device uses the relative movement of the Spreader roller and the substrate to achieve a uniform Spreader through a continuous scraping method. The thickness of the Spreader is precisely controlled by the dial meter indexing head fine-tuning the gap between the upper and lower rubber wheels, and the electric push rod provides a stable downward pressure to keep the gap constant. During the Spreader process, the electronic control system precisely adjusts the discharge tension to ensure the smooth operation of the material, and the heating device controls the temperature of the chute to meet the requirements of the hot-melt adhesive Spreader process.
Applications
Hot-melt adhesive, gel, hydrocolloid dressing, water-based glue, solvent glue
Steps
1. Adjust the PEEK baffle in the plastic slot to set the width of the Spreader
2. Fine-tune Spreader gap control thickness through dial meter indexing head
3. Set Spreader speed (2-4.5 m/min range)
4. Adjust the control panel knob to set the discharge tension
5. Start the device for Continuous Spreader
6. After the Spreader is completed, use the quick disassembly function to disassemble the glue tank to clean up the residual glue
Notice
• Spreader thickness should be determined according to Stock characteristics, minimum 0.01mm is the reference value
• Coating surface density ≤ +/- 1.5% with substrate Measured value, excluding edge anomalies
• Film accuracy +/- 0.003mm depending on Stock characteristics
• Heating Temperature range from room temperature to 200 ℃
• The maximum substrate width does not exceed 300mm
• The maximum diameter of the rewinding and unwinding is ≤ 450mm
• Device power 1050W, need to use AC220V single phase power supply
