Description

Technical Field

[0002] Hot melt adhesive particles are a type of adhesive whose physical state can change reversibly at a specific temperature, while its chemical properties remain unchanged. Hot melt adhesive particles can be transformed from solid to liquid by heating within a certain temperature range, and quickly solidify after cooling, thus completing the bonding process. Hot melt adhesive particles are usually non-toxic and odorless, and are environmentally friendly glue products. Since they do not contain solvents, they are safer and pollution-free during packaging, transportation and storage. Hot melt adhesive particles usually have greater bonding strength and can quickly bond a variety of materials, including textiles, paper, metal, etc., and are suitable for a variety of different industrial fields.

A drive belt is sleeved on the outer side of the drive shaft and the separator, and a leakage net is opened at the bottom of the separator. In the utility model, when the hot melt adhesive particles are transported to the separator, the coolant will penetrate to the bottom of the frame along the leakage net, the drive motor drives the drive shaft to rotate and thus drives the separator to rotate, and the coolant adsorbed on the surface of the hot melt adhesive particles will be thrown out of the separator through the leakage net under the action of centrifugal force, so that the device can use the centrifugal force generated by the rotation of the separator to separate the water particles from the hot melt adhesive particles, so that they can be dried quickly, and the efficiency of the production of hot melt adhesive particles is improved.
