[0002] Glue dispensing machines, also known as glue coating machines, glue dripping machines, glue spraying machines, and glue filling machines, are automated machines that control and apply fluids to the surface or interior of products. They can achieve three- and four-dimensional dispensing, precise positioning, and precise glue control without stringing, leaking, or dripping. Dispensing machines are primarily used to precisely dispense, inject, apply, or drip glue, paint, and other liquids to precise locations on each product during production processes. They can be used to create dots, lines, circles, or arcs.

[0003] Some existing dispensing machines require replacing different dispensing heads to change the output glue volume. Replacing different dispensing heads is cumbersome and affects work efficiency. Utility Model Content

[0032] The right side of the boost cylinder 15 is fixedly connected to an air intake pipe 16, and the air intake pipe 16 is connected to the inner wall of the dispensing machine housing 8. The right side of the boost cylinder 15 is fixedly connected to an air intake pipe 2 17, and the air intake pipe 2 17 is connected to the inner wall of the dispensing machine housing 8. The bottom of the boost cylinder 15 is fixedly connected to an air intake pipe 3 18, and the air intake pipe 3 18 is connected to the inner wall of the dispensing machine housing 8.

[0033] A fixing rod 19 is fixedly connected to the right side of the inner wall of the intake pipe three 18, a limiting block 20 is fixedly connected to the outer wall of the fixing rod 19, a sliding rod 21 is slidably connected to the inner wall of the fixing rod 19, a spring 22 is fixedly connected to the right side of the limiting block 20, a closing plate 23 is fixedly connected to the right side of the sliding rod 21, the right side of the spring 22 is fixedly connected to the left side of the closing plate 23, and the closing plate 23 is in contact with the inner wall of the intake pipe three 18.

[0035] The implementation principle of a dispensing head for a dispensing machine in the embodiment of the present application is as follows: by running the glue pump 25, the glue pump 25 delivers glue to the inside of the glue inlet pipe 24 through the glue extraction hose 26, and the glue inside the glue inlet pipe 24 is transported to the bottom of the inner wall of the dispensing machine shell 8, and then transported to the inside of the dispensing head 1. When it is necessary to adjust the amount of glue discharged by the dispensing head 1, the adjusting knob 2 is rotated, the adjusting knob 2 engages the gear 5, the gear 5 rotates the threaded rod 4, and the threaded rod 4 causes the lifting slider 6 to rise along the outer wall. After the lifting slider 6 rises, the glue dispensing is increased. The length of the inner wall of the head 1 is squeezed, thereby adjusting the amount of glue output. After the adjustment is completed, the booster cylinder 15 is operated, and the booster cylinder 15 pressurizes the inner wall of the air inlet pipe 16. The air inlet pipe 16 pressurizes the top of the air pressure separation ring 11, so that the top space of the dispensing machine housing 8 expands, and the air pressure separation ring 11 moves downward. The air pressure separation ring 11 drives the slide rod 10, and the inner wall of the slide rod 10 moves downward along the outer wall of the air pressure separation ring 11, and then the air pressure separation ring 11 pushes the injection rod 14, so that the injection rod 14 moves downward to promote the dispensing. The glue wrapped by the lifting slider 6 on the inner wall of the head 1 is squeezed out toward the nozzle 7, and then the booster cylinder 15 pressurizes the inner wall of the air intake pipe 2 17, so that the air intake pipe 2 17 pressurizes the bottom space of the air pressure separation ring 11, and then the air pressure separation ring 11 moves upward. The upward movement of the air pressure separation ring 11 drives the injection rod 14 to move upward, preparing for the next extrusion. When it is necessary to extrude the linear rubber strip, the booster cylinder 15 is operated to pressurize the air intake pipe 3 18, and the air intake pipe 3 18 closes the plate 23. Pushing toward the inside of the dispensing machine housing 8, the closing plate 23 drives the slide bar 21 to move outward, and the inner wall of the slide bar 21 slides along the outer wall of the fixed rod 19 toward the inner wall of the dispensing machine housing 8. At the same time, the closing plate 23 drives the spring 22 to move toward the inner wall of the dispensing machine housing 8, so that the pressurized gas inside the air inlet pipe 3 18 is transported to the bottom of the colloid isolation ring 13. The pressurized gas emitted by the air inlet pipe 3 18 squeezes the glue at the bottom of the colloid isolation ring 13 along the inside of the dispensing head 1 toward the nozzle 7, thereby squeezing out a linear glue strip.
