Description

Technical Field

[0001] The utility model relates to the technical field of liquid quantitative measurement, in particular to a liquid quantitative device which is convenient for adding auxiliary materials. Background Art

[0002] In the food production process, especially in the processing of noodle foods, dough kneading is required, and when kneading the dough, water-soluble auxiliary liquid needs to be added in a quantitative manner to ensure the flexibility and strength of the dough and improve the taste and mouthfeel of the processed food.

[0003] A liquid doser is required when adding auxiliary liquid. Traditional liquid dosers have an inlet pipe and an outlet pipe. Liquid is sucked in by the inlet pipe and discharged by the outlet pipe. However, during repeated operations, liquid will remain in the outlet pipe. When the doser sucks in liquid from the inlet pipe, the residual liquid in the outlet pipe will flow back into the doser. Moreover, the amount of liquid remaining in the outlet pipe is uncontrollable each time the liquid is discharged, which will cause errors in the discharge amount of the doser. For this reason, we propose a liquid doser that is convenient for adding auxiliary materials. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example:

[0023] See also Figure 1-Figure 4 Both ends of the bottle are connected with the bottle cap 14, and the bottle cap is connected with the bottle cap to the outer cover of the bottle.

[0024] Some embodiments of the present application are described in detail below with reference to the accompanying drawings:

[0025] See also Figure 1-Figure 4 When the liquid is sucked from the storage tank 1 into the metering cylinder 4, the blocking beads 9 in the liquid inlet pipe 5 leave the entrance of the channel 8, while the blocking beads 9 in the liquid outlet pipe 6 block the entrance of the channel 8, ensuring that the liquid in the liquid inlet pipe 5 flows normally into the metering cylinder 4 while preventing the liquid in the liquid outlet pipe 6 from flowing back into the metering cylinder 4.

[0026] Among them, the driving component 2 includes an electric push rod 11, a mounting bracket 12 is fixed on the top of the metering cylinder 4, the electric push rod 11 is fixed on the top of the mounting bracket 12, the output end of the electric push rod 11 is located in the mounting bracket 12, and a fixing rod 13 is fixed to the output end of the electric push rod 11. The bottom end of the fixing rod 13 passes through the top of the metering cylinder 4 and is fixed with a piston 14. The piston 14 is slidably arranged in the metering cylinder 4 to control the liquid in and out of the metering cylinder 4.

[0027] Furthermore, the extrusion assembly 10 includes an elastic telescopic rod 15, a support frame 16 is fixed in the fixed tube 7, the elastic telescopic rod 15 is fixed to the side of the support frame 16 close to the channel 8, and the sealing bead 9 is fixed to the movable end of the elastic telescopic rod 15 to control the opening and closing of the liquid inlet pipe 5 and the liquid outlet pipe 6.

[0028] The fixed rod 13 is driven by the electric push rod 11 to move, pulling the piston 14 upward, forming a negative pressure in the metering cylinder 4. At this time, the auxiliary material solution in the storage tank 1 enters the liquid inlet pipe 5, flows through the channel 8 in the fixed tube 7 of the liquid inlet pipe 5, squeezes the sealing ball against the entrance of the channel 8, and allows the sealing ball to leave the entrance of the channel 8, thereby completing the operation of the liquid in the storage tank 1 entering the metering cylinder 4. When the amount of liquid in the metering cylinder 4 reaches the required amount, the pressure in the metering cylinder 4 is equal to the pressure in the storage barrel. At this time, the sealing ball 9 in the liquid inlet pipe 5 is against the entrance of the channel 8 under the action of the elastic telescopic rod 15, preventing the liquid from flowing back into the storage tank 1. The fixed rod 13 is driven by the electric push rod 11 to move, pushing the piston 14 downward, and the liquid enters the liquid outlet pipe 6, flows through the channel 8 in the liquid outlet pipe 6, squeezing the sealing ball at the entrance of the channel 8 in the liquid outlet pipe 6, pushing the sealing ball away from the entrance of the channel 8, thereby connecting the inside of the liquid outlet pipe 6 and discharging the measured liquid.

[0029] During repeated operations, when there is residual liquid in the liquid outlet pipe 6 and the metering cylinder 4 begins to suck liquid from the liquid inlet pipe 5, the blocking ball in the liquid outlet pipe 6 is pressed against the entrance of the channel 8 under the action of the elastic telescopic rod 15, preventing the flow of liquid in the liquid outlet pipe 6, thereby preventing the liquid in the liquid outlet pipe 6 from flowing back into the metering cylinder 4 and affecting the accurate quantification of the liquid.

[0030] Since the channel 8 is hourglass-shaped and the size of the blocking bead 9 is larger than the inner diameter of the narrow opening of the channel 8, when the blocking bead 9 is against the entrance of the channel 8, its outer side can fit perfectly with the inner side of the channel 8 to block the entrance of the channel 8. The hourglass-shaped channel 8 also facilitates the smooth passage of liquid through the channel 8, thereby increasing the flow rate and pressure of the liquid in the channel 8.

[0031] When the sealing ball moves away from the entrance of the channel 8 under the pressure of the liquid, the support frame 16 is squeezed by the elastic telescopic rod 15. At this time, since the support frame 16 is conical and the support frame 16 gradually shrinks from the side away from the channel 8 to the side close to the channel 8, and the elastic telescopic rod 15 is arranged on the side of the support frame 16 close to the channel 8, the force exerted on the elastic telescopic rod 15 can be transferred from the support frame 16 to the inner wall of the fixed tube, thereby reducing the deformation of the support rod.

[0032] See also Figure 1 In this embodiment, a support column 18 is fixedly provided on the outside of the top of the storage tank 1, and a motor 19 is fixed on the top of the support column 18. A driving rod 20 is provided at the output end of the motor 19. The driving rod 20 passes through the support column 18 and the side of the storage tank 1 and is fixed with a gear 21. A stirring frame 22 is provided for rotation inside the storage tank 1, and annular teeth 23 that mesh with the gear 21 are evenly provided on the inner side of the top of the stirring frame 22 to ensure uniform concentration of the liquid in the storage tank 1.

[0033] By arranging a rotatable stirring frame 22 in the storage tank 1, the stirring frame 22 is driven to rotate by the cooperation of the motor 19, the drive rod 20, the gear 21 and the ring gear 23, and the stirring frame 22 is used to stir the liquid in the storage tank 1, so as to ensure that the concentration of the liquid in the storage tank 1 is uniform, and the solute sinking of the liquid in the storage tank 1 after being stored for a long time can be avoided.
