The first pressure plate is horizontally positioned, and its dimensions match those of the glue container. The bottom surface of the first pressure plate is concave. The second pressure plate is horizontally positioned directly below the first pressure plate, and the shape and dimensions of its outer surface are the same as those of the first pressure plate. A first through-hole is formed at the center of the second pressure plate, corresponding to a glue outlet. Multiple sets of second through-holes are formed on the second pressure plate in the area from the first through-hole to the edge of the second pressure plate. Each set of second through-holes includes several second through-holes, which are arranged in a circular pattern with the center of the first through-hole as the center. The multiple sets of second through-holes are spaced apart. The edge of the second pressure plate is fixedly connected to the edge of the bottom surface of the first pressure plate. By adding a second pressure plate, this application enhances the residual glue adhesion function, allowing most of the residual glue to remain on the second pressure plate for secondary use.

Description

Technical Field

[0001] This utility model relates to the technical field of glue applicators, specifically to an energy-saving glue applicator. Background Technology

[0002] Adhesive coating is widely used in the automotive industry, playing a crucial role in sealing, waterproofing, shock absorption, and support. Currently, the bottom surface of the pressure plate of adhesive coating machines in the industry generally adopts a concave structure design. This design aims to ensure that when the pressure plate of the adhesive coating machine is pressed down, the adhesive in the glue bucket can flow smoothly to the glue outlet pipe through the concave structure, thus ensuring the smoothness of the glue dispensing process. However, this structure has certain drawbacks. The concave hollow structure means that the adhesive in the glue bucket cannot be fully utilized. When changing the glue bucket, as the pressure plate of the adhesive coating machine is raised, some residual adhesive on the pressure plate will fall back into the bucket due to gravity and remain there. This not only leads to a waste of raw material costs, but also increases the hazardous waste disposal costs as the residual adhesive is a hazardous chemical. Existing technology uses manual cleaning and reuse to deal with the residual adhesive in the glue bucket, but this results in secondary pollution from the residual adhesive and low operational efficiency.

[0005] Preferably, the second through hole is an isosceles trapezoid, the inner wall of the second through hole near the first through hole and the inner wall away from the first through hole are parallel, and the size of the inner wall of the second through hole near the first through hole is smaller than the size of the inner wall away from the first through hole, and the adjacent inner walls of two adjacent second through holes in the same group are parallel to each other.

[0007] Preferably, the second through hole group is provided in four groups, which are arranged sequentially along the direction away from the first through hole as the second through hole group 1, the second through hole group 2, the second through hole group 3 and the second through hole group 4.

[0012] Preferably, the surface of the second pressure plate is treated with titanium plating using hard anodizing technology.

[0013] This utility model discloses an energy-saving glue applicator, which has the following beneficial effects:

[0014] This application involves installing a second pressure plate below the first pressure plate. When adhesive application is required, the adhesive applicator body drives the first pressure plate downwards within the adhesive container, causing the pressure below the first pressure plate to be greater than the pressure above it. Driven by this pressure difference, the adhesive in the container flows out through the dispensing hole for supply. As the first pressure plate moves downwards, it drives the second pressure plate downwards synchronously. The adhesive flowing out of the dispensing hole first passes through several second through-holes on the second pressure plate, resulting in some adhesive remaining between these second through-holes on the top surface of the second pressure plate. The adhesive is placed in the interval area between the second through hole and the interval area between the first through hole. During the drum replacement process, some residual adhesive on the first pressure plate falls due to gravity and first lands in the interval area between the second through holes and the interval area between the first through hole and the second through hole on the top surface of the second pressure plate. This portion of adhesive remaining in the interval area between the second through holes and the interval area between the first through hole and the second through hole on the top surface of the second pressure plate will be reused together with the adhesive in the new glue drum, reducing the residual adhesive in the glue drum, thereby effectively reducing the waste of raw material costs and hazardous waste disposal costs.

[0015] By opening a first through hole at the center of the second pressure plate and designing multiple rings of second through holes at intervals in other areas of the second pressure plate, and designing several isosceles trapezoidal second through holes distributed around the first through hole in each group of second through holes, it can be ensured that the glue flow rate is not affected during the glue supply process, so that the amount of glue remaining on the second pressure plate is maximized.
