[0021] The present invention provides a glue supply gear pump with an anti-blocking structure through improvement. Figure 1-Figure 9 As shown, it includes a pump body 1 and an anti-blocking mechanism 2. The pump body 1 includes two sets of first shell covers 101 and second shell covers 102 spliced ​​with each other.

When the conveying motor 106 is started, under the cooperation of the driving gear 107 and the driven gear 104 on both sides, the two sets of meshing conveying gears 103 inside the pump body 1 are quickly started, and a vacuum state is formed inside the pump body 1 at this time. When the conveying gear 103 drives the scraping fans 114 on both sides to rotate, the scraping fans 114 can quickly clean the inner walls on both sides of the pump body 1. The knocking part 115 on one set of blades on the scraping fan 114 will intermittently hit the protrusion 120 on the arc cleaning plate 118. Under the action of the elastic member 119, the arc cleaning plate 118 will reciprocate in the motion chamber 116, thereby scraping the inner walls of the pump body 1 around the cleaning port 117 to clean.

[0028] In this embodiment: when the conveying gear 103 drives the scraping fans 114 on both sides to rotate, the scraping fans 114 can quickly clean the inner wall to prevent the colloid with high viscosity from adhering to the inner wall. At this time, the knocking part 115 on the scraping fan 114 will intermittently hit the protrusion 120, and under the action of the elastic member 119, the arc cleaning plate 118 will reciprocate in the movement cavity 116, thereby scraping against the cleaning port 117 and cleaning the inner walls around the first shell cover 101 and the second shell cover 102.

[0034] In this embodiment: when the deformable gear ring 215 rotates counterclockwise, the cleaning arc plate 206 moves toward the middle of the flip cylinder 201 along the telescopic cavity 204 under the pressure of the arc-shaped convex seat 217, and the inner diameter of the cleaning arc plate 206 is reduced and separated from the nozzle 112 and the glue spraying tube 111, so as to facilitate the replacement of the nozzle 112. When the deformable gear ring 215 rotates clockwise, the arc-shaped convex seat 217 is separated from the cleaning arc plate 206, and the cleaning arc plate 206 moves toward the outside of the flip cylinder 201 along the telescopic cavity 204 driven by the return spring 209, and the inner diameter of the cleaning arc plate 206 is enlarged and abuts against the inner wall of the nozzle 112 and the glue spraying tube 111.

[0035] See attached Figure 6 and attached Figure 8 A scraping portion 207 is provided on the side of the cleaning arc plate 206 .

[0036] In this embodiment, in order to further improve the cleaning effect and avoid colloid residue, an inclined scraping portion 207 is designed.

[0038] In this embodiment: in order to ensure that the deformable gear ring 215 rotates freely relative to the rotating chamber 210, a track 211 and a groove 216 structure that cooperate with each other are designed. In order to drive the deformable gear rings 215 on the upper and lower sides to rotate synchronously, so as to further adjust the inner diameter of the cleaning arc plate 206, a dual-axis motor 213 structure is designed. In the initial state, that is, the cleaning arc plate 206 abuts against the inner wall of the flip cylinder 201 and the inner diameter is the largest, at this time, the right angle side of the arc-shaped protrusion 217 abuts against the outer wall of the cleaning arc plate 206. This design can further improve the stability of the cleaning arc plate 206 during rotation and scraping.

When the conveying gear 103 drives the scraping fans 114 on both sides to rotate, the scraping fans 114 can quickly clean the inner walls on both sides of the pump body 1. The knocking part 115 on one set of blades on the scraping fan 114 will intermittently hit the raised part 120 on the arc cleaning plate 118. Under the action of the elastic member 119, the arc cleaning plate 118 will reciprocate in the motion chamber 116, thereby scraping the surrounding inner walls of the pump body 1 with the cleaning port 117 for cleaning. When the cleaning motor 124 is started, the flip cylinder 201 will rotate freely relative to the mounting cavity 121 , and the cleaning arc plate 206 will scrape the inner wall of the nozzle 112 and the glue spraying tube 111 back and forth.
