Description

Technical Field

[0001] The utility model relates to the technical field of dispensing devices, and in particular, to a vacuum degassing glue bucket and a glue supply device. Background Art

[0002] When a dispensing machine works, it needs to be connected with a glue supply device to supply glue to a dispensing valve, so as to achieve a continuous glue output effect. At present, the glue supply device generally directly uses an air pump to extract glue from a glue bucket into the dispensing valve for dispensing. However, since some glues have high viscosity and are prone to generate bubbles when contacting with air, which seriously affects the dispensing effect. Moreover, the viscosity of the glue will increase due to temperature influence, resulting in the need to use a larger glue extraction pump to extract the glue from the glue bucket to the dispensing valve. On the one hand, it increases the equipment cost, and on the other hand, it also affects the dispensing effect. Summary of the Utility Model
