[0030] Working principle: When using the dispensing machine, first, the liquid inside the storage tank 8 is pumped into the inside of the dispensing nozzle 5 through the connecting pipe 10 by connecting the pump 9. Then, the connecting rod 3 is squeezed by the hydraulic device 4, so that the dispensing nozzle 5 approaches the product. Then, dispensing is achieved through the dispensing nozzle 5. When using the cleaning device 6, first, the connecting block 614 is slid to the appropriate position inside the connecting groove 613 according to the thickness of the product. Then, the first bolt 615 is manually rotated, so that the first bolt 615 squeezes the rubber plate 616, causing the rubber to be squeezed and deformed, so that the connecting block 614 can be well fixed inside the connecting groove 613. When the dispensing nozzle 5 is dispensing, the dispensing head is slid through and inserted into the top of the support arm 601, so that the dispensing head is inserted into the inside of the flexible cone 602. Then, the flexible cone 602 is well opened through the opening 603. After dispensing is completed, the dispensing head moves away from the support arm 601. Then, when the flexible cone 602 is involved, the flexible cone 602 contracts, and the glue at the bottom of the dispensing head is squeezed to the bottom of the flexible cone 602 through the polymerization at the bottom of the flexible cone 602. Then, the sliding rod 607 is manually pulled, so that the scraper 606 slides well inside the chute 605, making the scraper 606 approach the rubber arc plate 611. Then, the glue on the scraper 606 is well scraped into the inside of the rubber arc plate 611 through the rubber arc plate 611. The rectangular plate 610 is manually pulled out of the rectangular groove 609, so that the rubber block 612 is compressed, so that the rectangular plate 610 can move away from the support arm 601, which is convenient for cleaning the glue. Then, after dispensing is completed, the glue on the dispensing head can be automatically cleaned. When using the limiting device 7, the U-shaped plate 701 is manually inserted into one side of the operating table 1. When it is inserted into the appropriate position, the second bolt 707 is manually rotated, so that the second bolt 707 squeezes one side of the U-shaped plate 701, so that the U-shaped plate 701 is well set inside the operating table 1. Then, the round rod 702 is manually controlled to rotate, so that the limiting strip 704 is set in a suitable position. When the round rod 702 is rotated to the appropriate position, the third bolt 705 is manually rotated, so that the third bolt 705 squeezes the top of the rubber ring 706, causing the rubber to be squeezed and deformed, so that the round rod 702 can be well fixed on the top of the U-shaped plate 701. Then, the product is set on one side of the limiting strip 704. When the product moves on one side of the limiting strip 704, the roller 710 rotates on the surface of the rotating rod 709, so that the product can move well on one side of the limiting strip 704, so that the product can move along any direction.
