With the development of technology, the requirement for the storage accuracy of the filling and metering structure is getting higher and higher. However, when high-pressure air flow enters the inside of the filling and metering structure, spraying of materials easily occurs at the connection between the metering cup hole and the material guiding head, thus affecting the accuracy of material guiding. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a filling and metering structure with air flow blowing materials from top to bottom, which solves the technical problem that the existing filling and metering structure is prone to material spraying.

[0020] The following clearly and completely describes the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Many specific details are set forth in the following description in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0021] Such as Figure 1 、 Figure 2As shown in the figure, the utility model discloses a filling and metering structure with air flow blowing materials from top to bottom, which includes a turntable 1, a blowing head 2, a sealing head 3 and a sealing ring 4. A rotating shaft 8 is key-connected to the middle of the turntable 1, and the rotating shaft 8 is in transmission connection with a servo motor. During use, the servo motor can drive the rotating shaft 8 to rotate, and the rotating shaft 8 can drive the turntable 1 to rotate. Materials are placed on the top of the turntable 1. To prevent the materials from falling from above the turntable 1, a layer of material retaining plate 12 is fixedly arranged on the outer ring of the top of the turntable 1. A material storage groove 13 is arranged inside the material retaining plate 12. The material storage groove 13 is opened on the top of the turntable 1. The material storage groove 13 is annular, and materials are stored in the material storage groove 13. A plurality of metering cup holes 11 penetrating the turntable 1 are opened at the bottom of the groove of the material storage groove 13. As Figure 2 shown, with the central axis of the turntable 1 as the center axis, the metering cup holes 11 are equally spaced near the outer edge of the turntable 1.

[0022] A sealing head 3 is press-connected to the top of the metering cup hole 11. A blowing head 2 is hermetically connected to the top of the sealing head 3. Under the pressure of the blowing head 2, the sealing head 3 is pressed on the top of the turntable 1. The blowing head 2 is suspended above the turntable 1 through a supporting component. The supporting component can be any component with a supporting function, as long as it can suspend the blowing head 2 above the turntable 1, ensure that the blowing head 2 does not move with the turntable 1, and at the same time ensure good sealing between the sealing head 3 and the turntable 1. For example, the supporting component can be a support frame. The support frame is fixedly connected to the blowing head 2 and is fixedly connected to a part outside a filling and metering structure with air flow blowing materials from top to bottom.

[0023] Please continue to refer to Figure 1 , and an air inlet pipe 9 is hermetically connected above the blowing head 2. The air inlet pipe 9 is connected to a high-pressure air flow machine 10.

[0024] A sealing ring 4 is hermetically connected to the bottom of the turntable 1. The sealing ring 4 can prevent materials from falling out from the bottom of the metering cup hole 11, that is, the sealing ring 4 functions as the bottom of the metering cup hole 11. The sealing ring 4 also does not rotate with the turntable 1. As an installation method of the sealing ring 4, a support plate 6 is fixed to the bottom of the sealing ring 4. The support plate 6 is fixedly connected to the outside of a filling and metering structure with air flow blowing materials from top to bottom. A rotating shaft 8 is arranged in the middle of the support plate 6, and the rotating shaft 8 is separated from the support plate 6, that is, the rotating shaft 8 does not drive the support plate 6 to rotate. A material guiding channel 41 is opened on the sealing ring 4. As the turntable 1 rotates, the metering cup hole 11 can rotate above the material guiding channel 41, so that the materials can fall.

[0025] A material guiding head 7 is arranged in the material guiding channel 41. The top of the material guiding head 7 is hermetically connected to the bottom of the metering cup hole 11. The material guiding head 7 penetrates through the support plate 6, and the bottom end of the material guiding head 7 extends below the support plate 6. A gas flow amplifier 5 is hermetically connected to the bottom of the material guiding head 7. The top of the gas flow amplifier 5 is communicated with the material guiding head 7. An air inlet hole 51 is formed in the side wall of the gas flow amplifier 5, and an air outlet hole 52 is formed in the bottom of the gas flow amplifier 5. High-pressure gas can enter the gas flow amplifier 5 from the air inlet hole 51 and then be discharged from the air outlet hole 52.

[0026] During use, first place the material in the storage tank 13, and then start the servo motor. The servo motor drives the rotating shaft 8 to rotate, further driving the turntable 1 to rotate. At this time, the scraper (not shown in the figure and the scraper does not rotate with the turntable 1) suspended on the top of the turntable 1 can scrape the material into the metering cup hole 11. Since the metering cup hole 11 is not communicated with the material guiding channel 41 at this time, the sealing ring 4 can prevent the material from falling out of the metering cup hole 11. When the metering cup hole 11 filled with the material rotates above the material guiding channel 41, at this time the metering cup hole 11 is communicated with the material guiding head 7. One-way high-pressure gas enters the air inlet pipe 9 from the high-pressure gas machine 10 and then enters the blowing head 2. The high-pressure gas blows the material into the material guiding head 7; another way of high-pressure gas enters the gas flow amplifier 5 from the air inlet hole 51. Since there is also high-pressure gas passing through the top of the gas flow amplifier 5, the air outlet hole 52 is in a negative pressure state, and the gas flows along the Figure 1 arrow direction in the gas flow amplifier 5. With the cooperation of the two-way high-pressure gas, the material sequentially passes through the metering cup hole 11, the material guiding head 7 and the gas flow amplifier 5 and is blown into the packaging bag by the high-pressure gas.

[0027] In actual work, the material in each metering cup hole 11 is defined as a unit weight. According to the number of rotating metering cup holes 11, the metering size is determined. In this way, it is convenient to adjust the number of holes rotated each time on the human-machine interface, so as to achieve the function of continuous adjustment without stopping the machine.

[0028] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
