Description

Technical Field

[0001] This utility model relates to the field of glue supply equipment technology, and in particular to a flat-bottomed guide-type glue-saving pressure plate structure. Background Technology

[0002] Existing pressure plate designs all have a groove formed between the bottom of the pressure plate and the glue inlet at an angle of 3° to 30°. This groove lacks any structure to prevent glue dripping. While the groove is intended to accelerate glue flow, it also causes glue accumulation, resulting in a large amount of glue remaining in the groove and causing waste. In addition, when changing to new material, the pressure plate and the bottom of the container are not on the same plane. During the venting process, the glue in the groove is preferentially expelled, requiring a large amount of glue to be vented. Furthermore, the conical design of the pressure plate makes it inconvenient to clean residual glue.

[0003] Therefore, it is necessary to design a flat-bottomed, flow-guiding, glue-saving pressure plate structure to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flat-bottomed, flow-guiding, glue-saving pressure plate structure.

[0005] The technical solution of this utility model is: a flat-bottomed guide-type glue-saving pressure plate structure, including a flat-bottomed pressure plate body; a sealing ring that seals with the barrel wall is provided on the side wall of the flat-bottomed pressure plate body; a feeding plate is embedded in the center of the flat-bottomed pressure plate body; a plurality of feeding holes are evenly distributed on the feeding plate; the feeding holes on the feeding plate are opened according to the corresponding glue viscosity; the bottom surface of the feeding plate and the bottom surface of the flat-bottomed pressure plate body are on the same plane, and when the flat-bottomed pressure plate body extends into the bottom of the barrel, the bottom surfaces of the feeding plate and the flat-bottomed pressure plate body are in contact with the bottom of the barrel.

[0006] The outer wall of the flat-bottomed pressure plate body has multiple mounting grooves evenly distributed from top to bottom; each mounting groove is provided with a sealing ring.

[0007] The flat-bottomed pressure plate body has a through hole at its center; the feed plate is located at the through hole.

[0008] The feed hole has an irregular shape.

[0009] By adopting the above technical solution, this utility model has the following beneficial effects: This utility model forms a complete fit between the bottom of the flat-bottomed pressure plate body and the bottom of the bucket, so that the glue is completely squeezed out of the bucket, reducing glue waste from the source. At the same time, the feeding holes on each feeding plate are set according to the viscosity of the glue, ensuring that the glue adsorption area is increased and glue dripping waste is reduced when replacing new material.

[0014] Flat bottom pressure plate body 1, sealing ring 2, feed plate 3. Detailed Implementation

[0015] (Example 1)

[0016] See Figure 1 and Figure 2 This embodiment of a flat-bottomed flow-guiding adhesive-saving pressure plate structure includes a flat-bottomed pressure plate body 1; a sealing ring 2 is provided on the side wall of the flat-bottomed pressure plate body 1 to seal with the barrel wall; a feeding plate 3 is embedded in the center of the flat-bottomed pressure plate body 1; a plurality of feeding holes are evenly distributed on the feeding plate 3; the feeding holes on the feeding plate 3 are opened according to the corresponding adhesive viscosity; the bottom surface of the feeding plate 3 is on the same plane as the bottom surface of the flat-bottomed pressure plate body 1, and when the flat-bottomed pressure plate body 1 extends into the bottom of the barrel, the bottom surfaces of the feeding plate 3 and the flat-bottomed pressure plate body 1 are in contact with the bottom of the barrel.

[0017] Furthermore, in order to facilitate the installation of the sealing ring 2 and ensure the sealing between the sealing ring 2 and the barrel body, multiple mounting grooves are evenly distributed from top to bottom on the outer wall of the flat-bottomed pressure plate body 1; each mounting groove is provided with the sealing ring 2.

[0018] Furthermore, a through hole is provided at the center of the flat-bottomed pressure plate body 1; the feed plate 3 is located at the through hole.

[0019] Furthermore, the feed hole is irregularly shaped to increase the contact area between the feed hole and the adhesive, thereby improving the adhesive's adsorption effect and further avoiding adhesive waste.

[0020] The working principle of this embodiment:

[0021] When the pump is working, the entire flat-bottomed pressure plate body 1 is subjected to a downward pressure. The glue is continuously squeezed into the barrel to form a positive pressure. The glue is forced through the feed plate 3 and enters the pump body to complete the feeding process. When the flat-bottomed pressure plate body 1 is in complete contact with the bottom of the barrel, the glue feeding process is completed. When the barrel needs to be replaced, the flat-bottomed pressure plate body 1 detaches from the bottom of the barrel and finally separates completely from the barrel. The old glue barrel is pulled out. At this time, there is a gap without a glue barrel under the pressure plate. The feed plate 3 can increase the adhesion area of ​​the glue, reduce glue loss, and also reduce the pollution of the air by the chemical substances in the glue. In addition, the flat bottom of the pressure plate body 1 is easy to clean when there is residual glue over time.

[0022] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
