Jundingda Machinery ® Hot Melt Coating Glue Gun, also known as coating machine, scraping machine, automatic spraying machine, etc. A mechanical device mainly used to apply liquid glue to the surface of textiles, paper boxes, or leather. There are many styles of existing glue coating machines, such as drum glue coating machines, double action glue coating machines, and double station lifting glue coating machines. A coating machine is a device that uses air pressure to spray liquid such as glue or paint onto the desired product. The equipment adopts three-axis linkage, automated operation, and is equipped with computer programming control path spraying. The spraying thickness and time can be set, making it simple and easy to operate.
The performance of the glue coating machine not only affects the bonding quality of veneers, but also determines the amount of glue used, which affects the production cost of plywood. Therefore, there are the following technical requirements for the roller type glue coating machine.
1. Improve the uniformity of adhesive coating on the entire surface of the veneer. The specific measures are as follows:
(1) Ensure the manufacturing and installation accuracy of adhesive machine components. To ensure the full runout of the working surfaces of the coating roller and extrusion roller with respect to the axis, the parallelism of the upper and lower coating rollers, and the parallelism between the extrusion roller and the coating roller.
(2) Increase the diameter of the glue roller appropriately.
(3) According to the different types of rubber, the rubber covered by the glue roller should have different hardness, and the grooves on the surface of the roller should have different shapes and size specifications.
2. To adapt to different thicknesses of veneers, the spacing between the upper and lower coating rollers should be adjustable, and the thickness of the adhesive layer should be easy to control and adjust. The thickness of the adhesive layer is mainly determined by the gap between the extrusion roller and the coating roller, and the adjustment accuracy of this gap should be controlled at around 0.01mm. The coating amount is usually controlled within the range of 105-430g/m2.
3. Improve the wear and rust resistance of the components of the glue coating machine, install necessary safety protection devices to extend the lifespan of the glue coating machine and ensure safe operation.
