DETAILED DESCRIPTION

[0022] The utility model will be described in further detail below in combination with the drawings and specific embodiments.

[0023] In this embodiment, refer to Figures 1-7 The specific implementation of a kind of quantitative nozzle for mask filling, including support 1 and the shell 2 installed on support 1, the lower end of shell 2 is equipped with feed pipe 4 and discharge pipe 5 by electric valve 3 respectively, shell 2 is equipped with slidable piston rod 6, support 1 is equipped with the driving part 7 of cooperation with piston rod 6, the lower end of shell 2 is fixedly installed with the first sensor 8 of cooperation with piston rod 6, the upper end of shell 2 is equipped with slidable adjusting rod 9, one end of adjusting rod 9 is equipped with the second sensor 10 of cooperation with piston rod 6, the outside of adjusting rod 9 is equipped with a plurality of limiting grooves 9A, shell 2 is equipped with quick-mounting assembly 11 with limiting groove 9A cooperation. Through the electric valve 3 respectively equipped in feed pipe 4 and discharge pipe 5, thereby realizing the accurate control of feed and discharge. The outside of piston rod 6 is equipped with sealing ring, to ensure that sealing ring can effectively prevent liquid leakage in the movement process of piston rod 6, to improve the sealing property and reliability of filling process. In this embodiment, driving part 7 is single-acting cylinder, and the output end of single-acting cylinder is equipped with connecting block 12 for connection cooperation between piston rod 6. And first sensor 8 and second sensor 10 are contact sensor.

[0024] In the filling process, the mask solution is allowed to flow into the housing 2 by activating the electric valve 3 on the inlet pipe 4. At the same time, the injection of the mask solution will cause the piston rod 6 to move upwards as the electric valve 3 door of the outlet pipe 5 is in the closed state. When the piston rod 6 reaches the position set by the second sensor 10, the second sensor 10 will contact the piston rod 6 and send a signal to close the electric valve 3 on the inlet pipe 4 and stop the supply. At this time, the amount of mask solution in the housing 2 has reached the predetermined filling amount. After the container such as a packaging bag or a storage tank is ready, the mask solution is discharged through the outlet pipe 5 into the corresponding container by opening the electric valve 3 door of the outlet pipe 5 and sliding the piston rod 6 in the housing 2 by means of the cylinder drive. When the piston rod 6 completely discharges the mask solution and contacts the first sensor 8, the first sensor 8 will send a signal to stop the cylinder and close the electric valve 3 on the outlet pipe 5. Then, the electric valve 3 on the inlet pipe 4 is activated again to allow the mask solution to flow into the housing 2 for the next filling.

[0025] The quick-mounting assembly 11 includes a fixed shaft 11A, a sliding sleeve 11B, a return spring 11C, and a limiting block 11D cooperating with the limiting groove 9A. The fixed shaft 11A is arranged at the upper end of the housing 2 and is fixed by a screw. The sliding sleeve 11B is slidably arranged on one side of the fixed shaft 11A, and a clamping hoop is arranged on one side of the fixed shaft 11A to prevent the sliding sleeve 11B from falling off. A groove 111A for accommodating the limiting block 11D is arranged around the outer side of the fixed shaft 11A, and the limiting block 11D is slidably arranged in the groove 111A. The return spring 11C is arranged between the fixed shaft 11A and the sliding sleeve 11B. The limiting block 11D has a spherical structure. The spherical structure allows the limiting block 11D to roll back and forth in the groove 111A, so that the limiting block 11D can be quickly fixed or separated from the limiting groove 9A, thereby improving the response speed and operation convenience of the entire quick-mounting assembly 11.

[0026] When the adjusting rod 9 needs to be moved, pushing the sliding sleeve 11B can loosen the limiting block 11D and release the adjusting rod 9 from the limiting groove 9A. By cooperating the limiting block 11D with the limiting grooves 9A at different positions, the second sensor 10 can cooperate with the piston rod 6 at different positions, thereby controlling the filling amount in the housing 2. After moving, the sliding sleeve 11B will automatically return to the original position by the elastic force of the return spring 11C, so that the limiting block 11D cooperates with the limiting groove 9A again, thereby quickly fixing the adjusting rod 9.

[0027] In addition, the outer side of the sliding sleeve 11B is provided with a step shaft 111B extending outward. The design of the step shaft 111B increases the contact area of the sliding sleeve 11B, so that the user can press the sliding sleeve 11B more conveniently and quickly. Therefore, the comfort and accuracy of the operation are improved.

[0028] And, one end of the adjusting rod 9 is provided with an outwardly extending clamping block 9B. The size of the clamping block 9B is greater than the inner diameter of the fixing shaft 11A, so that after the limiting block 11D falls off the shedding limiting groove 9A, the adjusting rod 9 is not lost of limitation, and directly slides into the shell 2, thereby affecting the normal work of the quantitative nozzle.

[0029] The beneficial effects of the utility model are: through linkage cooperation between the electric valve 3, the piston rod 6, the driving part 7, the first sensor 8 and the second sensor 10, the filling amount of the mask solution is accurately controlled, so as to improve the filling precision and product quality. Moreover, through cooperation of the limiting groove 9A on the outside of the adjusting rod 9 and the quick-mounting assembly 11, the user can quickly adjust the filling amount according to the filling requirements of different masks, so as to improve the flexibility and convenience of the quantitative nozzle.
