Description

TECHNICAL FIELD

[0001] The utility model relates to the point gum technical field, specifically, especially, it relates to a glue feeding mechanism. BACKGROUND

[0002] At present, in various industrial production, will involve the point gum procedure, generally through the point gum device automatic completion, wherein the point gum device will connect the glue supply device and provide the glue for the point gum device;

[0003] However, in the existing glue feeding device, when the glue in the glue bucket is used up, the glue feeding device needs to be closed, and the point gum device will also stop working due to lack of glue. After replacing the glue bucket, it can continue to work again. The replacement of the glue bucket is very troublesome and time-consuming. For products with strict production rhythm requirements, it will affect the production capacity of industrial production. At present, the common air pressure feeding on the market will also cause air to enter the glue, resulting in voids in the final glue path, thereby affecting the related performance of the product. In addition, the other structure is that the piston in the glue bucket is pushed by the air cylinder to feed. However, due to the uneven force of the piston and the deformation of the glue bucket, the sealing between the piston and the glue bucket is affected, thereby causing glue leakage and unable to feed. At present, the existing feeding mechanism cannot monitor the remaining amount of glue in real time, and cannot discover the leakage of glue in time, thereby causing the complete waste of glue and pollution to the working environment. Replacing the glue bucket, the glue outlet of the glue bucket will have gas, which needs to be discharged by the point gum device. The glue in the glue flow channel / pipeline is wasted.
