Hot melt glue stick manufacturing process

Hot melt glue stick manufacturing process:

1. Weigh the raw materials according to the formula ratio of the hot melt glue stick and add them to the reaction kettle. Heat up to melt and stir well. Then cool the melted rubber in the reaction kettle to a certain temperature and put it into the running extruder. The extrusion speed of the extruder can be selected according to the different types of rubber. The extruder squeezes the hot-melt adhesive into the water tank through a trapped extrusion hole on the extrusion head, and the hot-melt adhesive is immediately shaped when it encounters cooling water. The tractor enters the second cooling water tank, and the glue sample is fully cooled and shaped in the second cooling water tank. The running speed of the glue stick in the water tank is controlled by the extrusion speed of the extruder, so that the traction speed of the tractor and the extrusion speed The extrusion speed of the machine is synchronized.

 

2. Adjust and control the relationship between extrusion speed, cooling and setting speed, and traction speed, and then cut and pack the cooled glue stick into finished products.
