Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve mechanism technology, and in particular to a high-frequency valve for dispensing or filling. Background Technology
[0002] In the fields of dispensing, filling, and ingredient mixing, high-frequency valves (generally referring to precision fluid control valves capable of rapidly opening and closing at very high frequencies) are crucial core components. Their necessity stems from several key needs: improving production efficiency and capacity: Modern production lines pursue high speeds. Whether it's precision dispensing on electronic assembly lines or filling or ingredient mixing lines for beverages / daily chemical products, fluid distribution for individual products needs to be completed in an extremely short time. High-frequency valves can achieve tens or even hundreds of opening and closing actions per second, thus keeping up with the pace of high-speed production lines and significantly increasing output per unit time.
[0003] However, the existing high-frequency valves are composed of parts such as valve body, valve disc, valve stem, valve cover, bracket, and actuator. The structure is complex, making it difficult to maintain and operate, and it is also difficult to apply them to dispensing, filling, or batching fields. Utility Model Content

Therefore, they should not be construed as limiting this utility model.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0021] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.
[0022] Example 1: like Figure 1-2 As shown in the embodiment of this application, a high-frequency valve for dispensing or filling is disclosed. After being connected to a power component, it can realize high-frequency feeding, such as being connected to a high-frequency air source. This application utilizes the cooperation of spring and gas to enable the rapid up and down movement of the inner impact pin, thereby realizing the rapid opening and closing of the feeding channel, which makes the feeding operation convenient.
[0023] like Figure 1 , 2 As shown, the specific structure of this application includes: The outer shell 1 has a cavity 101 inside, which can be used for other components and also facilitates the subsequent gas to lift the inner impact pin. Combined with the first spring, it can achieve reciprocating motion. The rotating head assembly 2 is installed on the top of the housing 1, and one end of the rotating head assembly 2 is located inside the cavity 101. The rotating head assembly 2 is used to seal the top of the cavity 101 to prevent external gas from affecting the stable operation of the entire valve. An air inlet 3 is connected to one side of the outer shell 1. The air inlet 3 is connected to an air source to generate power, thereby driving the inner striking pin to move. Fastener 4 is installed at the bottom of the housing 1, and the fastener 4 has a flow channel 5 inside, which facilitates the feeding of material into the subsequent feed inlet; The feed inlet 6 is connected to the outside of the fastener 4, that is, the material can enter the flow channel 5 from the feed inlet 6; The discharge head 7 is installed at the bottom of the fastener 4, and the discharge head 7 has a discharge channel 8 inside, which is connected to the flow channel 5, so that the material can flow out from the discharge channel 8; The inner impact pin 9 has one end set inside the cavity 101 and the other end extending downward to the top of the feeding channel 8. When the inner impact pin 9 moves upward, it can open the feeding channel 8 of the discharge head 7, and when it moves downward, it can block the feeding channel 8 of the discharge head 7. The first spring 10 is sleeved on the top of the inner impact pin 9. The first spring 10 and the air source of the air inlet 3 cooperate with each other to realize reciprocating motion. That is, the first spring 10 pushes the inner impact pin 9 to move down, while the gas in the air inlet 3 can push the inner impact pin 9 to move up, thereby completing the reciprocating motion.
[0024] In order to achieve the separation of gas and material, this application separates the flow channel 5 from the cavity 101, which can effectively achieve the separation of gas and material. The inner impact pin 9 is fitted with a second spring 11 in the middle. The top of the second spring 11 contacts the protrusion of the inner wall of the cavity 101 to form a compression, and the bottom compresses the subsequent separator sleeve, which helps to ensure the sealing. Specifically, a separator sleeve 12 is installed on the inner top of the flow channel 5. The separator sleeve 12 is located below the second spring 11 and between the air inlet 3 and the feed inlet 6. The separator sleeve 12 can be an existing structure, which only needs to achieve isolation.
[0025] In order to achieve stable upward and downward movement, thereby completing the blocking or opening of the feeding channel 8, the inner impact pin 9 described in this application is an integrally molded part, and the inner impact pin 9 includes: The upper pressure section 901 is cross-shaped and located between the first spring 10 and the air inlet 3. The upper pressure section 901 is subjected to the pressure of the first spring 10 to achieve balance with the gas pressure of the remaining part of the cavity (separation is achieved through the partition sleeve). A transition section 902 is disposed at the bottom of the upper pressing section 901, and the second spring 11 is sleeved on the transition section 902; The pressing section 903 is located at the bottom of the transition section 902 and at the top inner part of the feeding channel 8. That is, the feeding channel 8 can be opened and closed by the movement of the inner impact pin 9.
[0026] To further ensure stability during opening and closing, the pressing section 903 described in this application is conical, and the diameter of the transition section 902 is not less than the inner diameter of the feeding channel 8, so that the feeding channel can be blocked.
[0027] To further ensure sealing, a first sealing ring 13 is provided between the outer wall of the upper pressure section 901 and the inner wall of the cavity 101, a second sealing ring 14 is provided between the outer wall of the fastener 4 and the inner wall of the cavity 101, and a third sealing ring 15 is provided between the outer wall of the discharge head 7 and the inner wall of the discharge channel 8. That is, multiple sealing rings can improve the sealing effect, thereby improving the stability of the valve supply.
[0028] To achieve adjustment of the first spring 10, the rotating head assembly 2 includes: Sleeve 201 is installed on the inner top of the outer casing 1; The rotating head 202 is threadedly assembled with the sleeve 201, and the bottom end of the rotating head 202 contacts the top of the first spring 10. That is, by moving the rotating head 202 up and down, the first spring 10 can be further tightened, thereby controlling the pressure on the inner impact pin 9.
[0029] A fourth sealing ring 16 is provided between the outer wall of the sleeve 201 and the inner wall of the cavity 101, which can further improve the sealing performance.
[0030] Further explanation is provided regarding this application: This application separates the gas and the material using a partition sleeve 12, with the gas area above and the material area below.
[0031] When the machine starts working, air is introduced through the air inlet 3, which pushes the upper pressure section 901 to move upward. At this time, the lower pressure section 903 moves upward as well, disengaging from the top of the feeding channel 8, and the material flows out from the feeding channel 8. When it is necessary to close the feeding channel 8, the air intake of the air inlet 3 is closed. At this time, the first spring 10 pushes the inner impact pin 9 to move downward, thereby closing the feeding channel 8 and thus achieving the closure of the feeding channel.
