Overview
The NBC-6025 small hot-melt adhesive continuous Film Applicator is a high-accuracy modular Spreader station assembly experimental equipment, suitable for continuous Spreader proofing in the laboratory or small batch production. The equipment can directly Spreader the hot-melt Pressure sensitive adhesive on the heat-resistant substrate, or first transfer the glue Spreader on the release paper to the surface of different materials such as paper, plastic, model metal film.
Features
1. The whole machine adopts High Accuracy Modular Spreader Station structure assembly.
2. Use the dial meter as the indexing head to precisely fine-tune the gap between the upper and lower rubber wheel Spreader. The minimum gluing Film thickness is 0.01mm. After the gap is set, it can be indirectly locked to prevent change.
3. The maximum Spreader width is 300mm (the effective Spreader width is 280mm), and the width is adjusted through the Teflon baffle in the glue slot. The unlimited length Spreader can be glued and automatically rewound.
4. Positive and reverse stepless speed change, Spreader speed 2-4.5 m/min adjustable, recommended speed 4.5m/min; discharge reel can adjust the knob to change the tension discharge, reel can adjust the mechanical tension control charge.
5. The heating rod, upper rubber wheel and rubber groove can be quickly disassembled and separated from the body to remove the residual glue.
Principle
The equipment adopts a continuous scraping method. The hot-melt adhesive is heated to a set temperature by a heating device, and the gap between the upper and lower rubber wheels is used to control the Spreader Film thickness. The Spreader forms a uniform film on the substrate. The Spreader process controls the speed by forward and reverse stepless speed change, and uses a baffle to adjust the width of the Spreader to realize continuous Spreader and automatic winding.
Applications
Laboratory Continuous Spreader Proofing, Small Batch Production, Hot-melt adhesive Spreader, Material surface preparation

Steps
1. Adjust the Teflon baffle in the glue slot to set the Spreader width.
2. Use the dial meter to fine-tune the gap between the upper and lower rubber wheels to control the Spreader Film thickness.
3. Set the heating temperature to the desired range (RT +~ 200 ° C).
4. Adjust Spreader speed (2-4.5 m/min) and forward and reverse.
5. Adjust the discharge reel knob to change the tension discharge.
6. Adjust the mechanical tension control of the receiving reel.
7. After the Spreader is completed, quickly disassemble the heating rod, the glue wheel and the glue tank to remove the residual glue.
Notice
• Spreader Film thickness and accuracy depends on the slurry, reference material requirements.
• Coating surface density measurement needs to include substrate, without edge abnormal area, sampling standard see product evaluation.
• The minimum film thickness of 0.01mm should be determined according to the characteristics of the slurry.
• Spreader speed is recommended to be 4.5m/min, which can be adjusted within 2-4.5 m/min according to actual needs.
• The equipment needs to be connected to 0.5-0 MPa compressed air source.
The heating temperature must not exceed the upper limit of 200 ° C.
• Regularly disassemble and clean the heating rod, glue wheel and glue slot to prevent the accumulation of residual glue.
