Common faults, causes and troubleshooting methods of hot melt glue machine of shoe machine assembly line

1. Fault phenomenon: the working material will draw the rubber roller

Cause: rubber roller temperature is not enough; The rubber material CPS is too high for the machine operation

Elimination method: readjust the roller temperature; Change the applicable type of glue machine

2. Fault phenomenon: the plastic storage bucket is melted and yellowed and carbonized

Cause: cots wheel temperature is too high; Coating time is too long; The adhesive time is too long; The adhesive material has poor antioxidant aging ability

Rule out: readjust the temperature of the roller to be subject to continuous silk; Intermittently stop the operation of the coating wheel; Reselect hot melt adhesive material

3. Fault phenomenon: the glue will be involved in the glue storage tank when the glue is coated

Cause: the gap between inclined iron and rubber roller is too large; Rubber roller temperature is insufficient; The working material is too thin and soft for roller coating

Exclusion method: adjust the clearance with a cross screwdriver for the best; Moderately increase the temperature of rubber roller; The selective spray type should be discontinued

4. Fault phenomenon: working material coating will be involved in the silica gel wheel

Cause: the silicone wheel has been pasted to the hot melt adhesive and not cleared; The working material has been coated with hot melt adhesive or other self-adhesive

Exclusion method: found immediately stop, with kerosene or white ore oil to clean up, then use. Because there is glue immediately stuck to the silicone wheel, the phenomenon of rewinding can not be used for secondary gluing with the adhesive working material.

5. Fault phenomenon: the roller is stuck and does not work

Cause: the bearing does not refueling for a long time and burns; The cloth scraps and miscellaneous slag are blocked in the rubber groove for a long time, and the roller resistance causes the motor to burn out due to excessive load

Exclusion method: replace the bearing; Long cleaning glue storage tank; Operate in strict accordance with operating procedures; Burned-out motor surprise overhaul accountability
