Description

Thermal insulation device for a nozzle of a sealer application apparatus The present invention relates to a heat transfer thermal insulation device, and more specifically, to a heat transfer thermal insulation device for a nozzle of a sealant application device. In the automotive production process, sealers play a crucial role in ensuring the waterproofing and dustproofing performance of vehicles. Generally, sealers are heated to a specific temperature before application to facilitate the process, and once applied, they harden to exhibit their intended performance. However, if the sealant's temperature is not properly maintained during the application process, its physical properties may deteriorate, leading to a decline in waterproofing and dustproofing performance, which can result in quality issues. In particular, if the application process is interrupted or the sealant remains in a standby state for a long time, the temperature of the sealant may drop rapidly. This can cause the sealant to harden or change viscosity, resulting in irregular application, and there is also a possibility of caustic non-compliance occurring while waiting for inspection. These problems not only reduce productivity but also have a negative impact on the quality of the vehicle. Therefore, thermal insulation technology is required to maintain the appropriate temperature of the sealant at the nozzle portion of the sealant application device and to prevent the sealant from hardening even under prolonged standby conditions.
