Description

Technical Field

[0001] The present application relates to the technical field of dispensing valves, and particularly to a high-viscosity fluid dispensing high-pressure valve. Background Art

[0002] A dispensing valve is an industrial application device mainly used to control the precise spraying and coating operations of liquids or semi-fluids. It is usually combined with automated equipment to ensure an efficient, accurate, and repeatable coating process. Dispensing valves are widely used in high-demand fields such as semiconductors, electronics, automobiles, medical devices, and aerospace.

[0003] A prior patent (publication number: CN220177367U) discloses a high-viscosity fluid dispensing high-pressure valve, which relates to the field of dispensing valves. The top of the dispensing rod is installed with a feed pipe for conveying a fluid medium. A pull rod is axially slidably installed inside the dispensing rod. The end of the pull rod in the initial state is used to seal the fluid medium. A scraping block for providing extrusion for the extrusion of the fluid medium is fixed on the outer wall of the pull rod. One end of the dispensing rod is fixedly installed with a cylinder for providing power for the movement of a push block through a connecting rod, and an adjusting mechanism is provided at the connection between the cylinder and the pull rod. By setting the adjusting mechanism, when using this device to perform dispensing operations on products, by adjusting the distance between the movable rod and the push block, the moving distances of the movable rod, the pull rod, and the scraping block are increased or decreased, thereby controlling the amount of fluid medium flowing out inside the dispensing rod, and there is no need to repeat dispensing multiple times, further increasing the working efficiency.

[0004] During the use of the above-mentioned dispensing high-pressure valve, by adjusting the distance between the movable rod and the push block, the moving distances of the movable rod, the pull rod, and the scraping block are increased or decreased, thereby controlling the amount of fluid medium flowing out inside the dispensing rod, and there is no need to repeat dispensing multiple times, further increasing the working efficiency.

[0033] Please refer to Figure 1 , Figure 3 and Figure 4 , a piston 4 is slidably inserted into the glue dispensing tube 3.

A spring 16 is fixedly connected between the return ring 6 and the glue dispensing tube 3. Through the arrangement of the spring 16, the purpose of resetting the piston 4 can be achieved. A closing rod 17 is fixedly connected to the right side surface of the piston 4. A conical plug 18 is fixedly connected to the right end of the closing rod 17. A sealing ring 19 is fixedly connected to the inner wall of the right end of the glue dispensing tube 3. The conical plug 18 contacts the sealing ring 19. Through the arrangement of the conical plug 18 and the sealing ring 19, the purpose of sealing the glue dispensing tube 3 can be achieved.

[0034] Please refer to Figure 1 , Figure 3 and Figure 4, a feed pipe 7 is fixedly connected to the right end of the dispensing tube 3. A screw blade 8 is provided inside the feed pipe 7, and the screw blade 8 is in close contact with the inner wall of the feed pipe 7. A heating wire 20 is installed on the outer surface of the dispensing tube 3. Through the setting of the heating wire 20, the purpose of heating the dispensing tube 3 can be achieved, avoiding the solidification of the glue liquid in the state of the equipment stopping working, resulting in the blockage of the dispensing tube 3. The bottom end of the feed pipe 7 is fixedly connected with a cross plate 21. A feeding shaft 22 is rotatably connected between the cross plate 21 and the top end of the feed pipe 7. The screw blade 8 is fixedly connected with the feeding shaft 22. Through the setting of the feeding shaft 22, the purpose of driving the screw blade 8 to rotate can be achieved, achieving the conveying effect of the material.

[0035] Please refer to Figure 1 , Figure 2 and Figure 3 , two adjusting plates 9 are fixedly connected to the left side surface of the reset ring 6. A bidirectional threaded rod 10 is rotatably connected between the two adjusting plates 9. Both ends of the bidirectional threaded rod 10 are threadedly connected with moving blocks 11. Both moving blocks 11 are in contact with the reset ring 6. The left ends of both moving blocks 11 are hinged with push rods 12. The left ends of both push rods 12 are hinged with the same adjusting rod 13. The adjusting rod 13 is slidably inserted into the push block 2.

[0036] Please refer to Figure 1 , Figure 3 and Figure 4 , distance measuring sensors 23 are fixedly embedded in the left end of the adjusting rod 13 and the left inner side wall of the push block 2 respectively. The two distance measuring sensors 23 are optically connected. Through the setting of the distance measuring sensors 23, the distance between the adjusting rod 13 and the push block 2 can be monitored. The top end of the bidirectional threaded rod 10 and the top end of the feeding shaft 22 are both fixedly connected to the output end of an external micro motor. Through the setting of the external micro motor, power can be provided for the rotation of the bidirectional threaded rod 10 and the feeding shaft 22.

[0037] In a high-viscosity fluid dispensing high-pressure valve in this embodiment, through the setting of the bidirectional threaded rod 10, the mutual approach or mutual separation between the two moving blocks 11 can be realized. Further, the adjusting rod 13 is pushed to move left and right through the two hinged push rods 12, achieving the effect of automatically adjusting the distance between the adjusting rod 13 and the push block 2. And with the cooperation of the two distance measuring sensors 23 arranged, the distance between the adjusting rod 13 and the push block 2 can be accurately monitored, facilitating the user to control the glue output. Through the setting of the heating wire 20, the purpose of continuously heating the dispensing tube 3 can be achieved, effectively avoiding the solidification of the glue liquid inside the dispensing tube 3. Through the setting of the screw blades, the glue liquid can be conveyed, improving the replenishment speed of the glue liquid.

[0038] It should be noted that the heating wire 20, the external motor and the distance measuring sensor 23 are all electrically connected to an external control host.

[0039] The working principle of the above embodiments is as follows. When in use, the external motor is driven to drive the bidirectional threaded rod 10 to rotate. During the rotation of the bidirectional threaded rod 10, the two moving blocks 11 are driven to approach each other, so as to drive the push rod 12 to push the adjusting rod 13 towards the push block 2. The distance between the push block 2 and the adjusting rod 13 can be monitored by the ranging sensor 23. Then, the auger blade 8 is driven to rotate to convey the glue into the inside of the dispensing tube 3. Immediately afterwards, the cylinder 1 is driven to drive the push block 2 to move. When the push block 2 contacts the adjusting rod 13, the adjusting rod 13, the reset disc and the piston 4 can be driven to move, so as to extrude the internal glue to overflow for dispensing operation.
