Company Profile

Suzhou Oushida Hot Melt Adhesive Machinery Equipment Co., Ltd. is a high-tech enterprise specializing in the research and development, production, sales and technical consulting of hot melt adhesive intelligent spraying equipment.

Hot melt glue machine, hot melt glue gun and hot melt glue hose
all have heating function, in order to prevent the hot melt glue from cooling during circulation, thus affecting the bonding effect of the product. What should I do if the hot melt glue hose or hot melt glue gun does not heat up? Today, I will briefly introduce several troubleshooting methods for you.

1. The heating wire (rod) is damaged: first check the wiring and measure the resistance value, and replace the heating wire after confirming the resistance.

2. Temperature sensor failure: Check the wiring and measure the resistance value, and replace it after confirmation.

3. Poor line contact: Check whether the line contact is loose.

4. Corresponding temperature control meter failure: Check whether the solid-state relay has an input DC signal.

5. Solid-state relay failure: Check and replace the solid-state relay

6. Is the fuse burned out: Check and confirm, if damaged, please replace a new fuse.

If the hot melt glue hoseand the  hot melt glue gunare not heated during use, the glue output stability will be affected. When the hot melt glue machineis used again, the solid glue in the hose or glue gun cannot melt and flow out, causing blockage, and the entire hot melt glue machinewill be unusable. Therefore, during the use of the entire hot melt glue machine, it is necessary to maintain and repair it on time to avoid delaying production and causing unnecessary trouble.
