Description

Technical Field

[0001] The utility model belongs to the technical field of pesticide production, and particularly relates to a quantitative filling valve for pesticide production. Background Art

[0002] A quantitative filling valve is a mechanical device used for liquid filling. Its main function is to accurately control the filling volume of liquid according to the preset amount. This equipment is widely used in industries such as food, beverage, pharmaceutical, and chemical, especially in situations where precise control of the filling volume is required.

[0003] Existing filling valves are generally controlled by solenoid valves or quantitative monitoring components. Although they can play a quantitative role in the production process, they need to be reprogrammed every time the packaging bottle is replaced or the filling volume requirement is changed. On the one hand, this prolongs the downtime of the production line and is not conducive to improving production efficiency. On the other hand, the rewritten program needs to be tested several times before it can be put into production, and the process will waste a lot of pesticides. Utility Model Content

[0004] The purpose of this utility model is to provide a quantitative filling valve for pesticide production, which can quickly adjust the filling volume according to the filling demand, and adopts a mechanical quantitative method, without the need for repeated programming, and is highly practical.

[0020] In order to make the purpose and advantages of this utility more clear, the utility is described in detail below with reference to the embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of this utility and does not strictly limit the scope of protection specifically requested by this utility.

[0021] like Figure 1-Figure 4As shown, a quantitative filling valve for pesticide production includes two connecting pipes 1, each of which is equipped with a valve 2 on its side wall, a quantitative disk 3 is provided between the two connecting pipes 1, and a plurality of quantitative holes 4 are provided on the top surface of the quantitative disk 3. The apertures of the quantitative holes 4 are all different, a driving part is provided on the lower side of the quantitative disk 3, and a sealing assembly is provided on the end surface of the two connecting pipes 1 close to the quantitative disk 3.

[0022] like Figure 2 As shown, the driving member includes a motor 6 fixedly mounted on the side wall of the lower connecting pipe 1 , the output end of the motor 6 is fixedly connected to a rotating shaft 5 , and the top end of the rotating shaft 5 is fixedly connected to the quantitative disk 3 .

[0023] Among them, the motor 6 can adopt any one of a servo motor, a stepper motor or other motors 6 to control its intermittent rotation, so that after a single rotation, the quantitative holes 4 are all corresponding to the connecting tube 1; in addition, a protective cover can be set on the outside of the motor 6 to protect it and reduce the overhead view caused by pesticides.

[0024] like Figure 2 and Figure 3 As shown, the sealing assembly includes a threaded sleeve 7 threadedly connected to the side wall of the connecting pipe 1 near the quantitative disk 3, an annular groove 8 is provided on the end face of the connecting pipe 1, and an annular plate 10 is provided between the connecting pipe 1 and the quantitative disk 3. The side wall of the annular groove 8 away from the quantitative disk 3 is fixedly connected with a plurality of springs 9, and the other end of the spring 9 is fixedly connected to the quantitative disk 3. The side wall of the annular plate 10 close to the quantitative disk 3 is fixedly connected with a sealing ring 11, and the end face of the connecting pipe 1 is provided with a sealing groove 12, and the sealing ring 11 is adapted to the sealing groove 12. The side wall of the threaded sleeve 7 is provided with a transmission part.

[0025] like Figure 4 As shown, the transmission part includes a mounting plate 13 fixedly connected to the side wall of the connecting pipe 1, two cylinders 14 are fixedly connected to the side wall of the mounting plate 13, and the output ends of the two cylinders 14 are fixedly connected to a rack 15. The side wall of the threaded sleeve 7 is fixedly connected to a number of evenly distributed tooth blocks 16, and the rack 15 is engaged with the tooth block 16.

[0026] Specifically, by setting up a sealing component, the gap between the connecting pipe 1 and the quantitative disk 3 can be sealed. By pressing down the threaded sleeve 7, the sealing ring 11 can be simultaneously pressed down into the sealing groove 12, thereby achieving efficient sealing of the gap and avoiding safety hazards caused by pesticide leakage. When other quantitative holes 4 need to be replaced, the cylinder 14 is reset, and the rebound force of the spring 9 is used to drive the sealing ring 11 out of the sealing groove 12 to facilitate the rotation of the quantitative disk 3.

[0027] like Figure 1-Figure 2 As shown, the quantitative holes 4 are distributed in a circular array around the center line of the quantitative disk 3. The side walls of the quantitative holes 4 are arranged in an arc shape, and the curvature of the side walls of the plurality of quantitative holes 4 increases in sequence.

[0028] Among them, when the motor 6 drives the quantitative disk 3 to rotate, the center of the quantitative hole 4 corresponds to the center of the connecting pipe 1. On the one hand, it avoids deviation during docking and causes pesticide leakage. On the other hand, it can make the sealing ring 11 accurately stuck in the sealing groove 12.

[0029] The working principle of the utility model is: first, the connecting pipe 1 is connected to the filling pipe, and then the filling amount is adjusted according to the demand. First, the motor 6 is started to drive the rotating shaft 5 to rotate. After the rotating shaft 5 drives the quantitative disk 3 to rotate to a suitable angle, the quantitative holes 4 between the connecting pipes 1 on both sides correspond to it, and then the cylinder 14 is started. The output end of the cylinder 14 drives the rack 15 to move, and the rack 15 engages the gear block 16 and drives the threaded sleeve 7 to rotate. When the threaded sleeve 7 rotates, it moves to one side of the quantitative disk 3. At the same time, the threaded sleeve 7 squeezes the annular plate 10 to drive the sealing ring 11 to be stuck in the sealing groove 12, which is used to seal the gap between the connecting pipe 1 and the quantitative disk 3 to achieve the purpose of efficient sealing. By setting quantitative holes 4 with different apertures, the correct amount of pesticide filling is achieved. When the pesticide is filled in the quantitative hole 4, the upper valve 2 is closed and the lower valve 2 is opened. When the pesticide is emptied, the lower valve 2 is closed and the upper valve 2 is opened to achieve quantitative filling.

[0030] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
