Description

Technical Field

[0001] The utility model relates to the technical field of defrosting thermostat production, in particular to a waterproof bag sealing device for a thermostat. Background Art

[0002] Due to the special application environment of the defrost thermostat, its temperature sensor and temperature limit fuse need to be waterproofed. The commonly used waterproofing method is to use a hot press sealing machine to heat-seal the temperature sensor and temperature limit fuse in a PVC waterproof bag.

[0003] When the current operators perform the sealing operation, they first use the hot press sealer to seal the cut PVC sleeve into a semi-finished waterproof bag with one end sealed, and then place the temperature sensor and the temperature limit fuse in the semi-finished waterproof bag, and use the hot press sealer to seal the other end. The two-step operation leads to low production efficiency. At the same time, because the leads of the temperature sensor and the temperature limit fuse need to be sealed outside the PVC waterproof bag, the hot press heads used to seal the two ends of the PVC sleeve are different, so two hot press sealers are required to operate, which increases the production cost.
