A plurality of one-way air valves (6) are provided, and the one-way air valves (6) correspond to the quantitative adjustment bags (5) one by one. The top surface of the support plate (14) is fixedly connected to the bottom surface of the material transmission plate (13); a side surface of the support plate (14) is fixedly connected to the outer side surface of the quantitative cylinder (4); the support plate (14) is placed between the auxiliary baffle (15) and the quantitative cylinder (4); the height of the support plate (14) is less than or equal to the height of the quantitative cylinder (4); the width of the support plate (14) is much smaller than the diameter of the outer side surface of the quantitative cylinder (4); The tipping sealing cover (7) is clamped on the bottom end of the metering cylinder (4).

The rotating connecting rod (1) extends from one end connected to the dumping sealing cover (7) along the length direction of the storage box (12) to the halfway point and is bent obliquely upward to the other end. The middle part of the two rotating connecting rods (1) is rotatably connected to the support plate (14) through a rotating shaft. A connecting plate (2) is fixedly disposed on the inner side surface of one of the rotating connecting rods (1) near the other end. One end of the tipping telescopic rod (3) is rotatably connected to the metering cylinder (4) via a rotating shaft, and the other end of the tipping telescopic rod (3) is rotatably connected to the connecting plate (2) via a rotating shaft. When in use, the metering cylinder (4) is first returned to its original position to ensure that the central axes of the metering cylinder (4) and the conveying cylinder (18) coincide with each other. Then, according to the amount of material to be quantitatively input, an appropriate number of quantitative adjustment capsules (5) are selected and air is injected into the quantitative adjustment capsules (5) to compress the internal space of the metering cylinder (4), thereby achieving control of the amount of material inside the metering cylinder (4). The material feeding sealing cover (16) is removed from the material storage box (12), and the material is injected into the material storage box (12) from the conveying hole at the top of the material storage box (12). The material will enter the metering cylinder (4) through the conveying cylinder (18).

According to the above steps, the quantitative input of the material can be realized. In addition, after working for a period of time, it is necessary to regularly add gas to the gas-filled quantitative adjustment bag (5) to ensure the accuracy of the material amount. Example 2

[0012] The difference between this embodiment and embodiment 1 is that a sealing ring (19) (19) is fixedly arranged on the side between the top and the half of the tipping sealing cover (7) (7), the sealing ring (19) (19) is in a circular ring structure, the sealing ring (19) (19) is made of rubber, a plurality of the sealing rings (19) (19) are provided, and the plurality of sealing rings (19) (19) are arranged equidistantly along the axial direction of the tipping sealing cover (7) (7), and when in use, the sealing ring (19) (19) can further seal the dosing cylinder (4) (4) and the tipping sealing cover (7) (7), thereby preventing the material from leaking out of the gap between the dosing cylinder (4) (4) and the tipping sealing cover (7) (7); Example 3

[0013] The difference between this embodiment and embodiment 1 is that the inner side surface of the dumping sealing cover (7) is covered with a ceramic coating (20). When in use, the ceramic coating (20) enables the material between the feed slope (17) and the storage box (12) to quickly slide into the conveying cylinder (18), thereby preventing the material from piling up. The material storage box (12) is a hollow structure, and a conveying hole is respectively opened at the top and bottom of the material storage box (12) near the middle. The hollow design provides space for material storage. The conveying holes at the top and bottom are respectively used for feeding and connecting with the dosing component, so that the material can smoothly enter the dosing component from the material storage box (12), thereby ensuring the continuity of material transmission of the entire device; The design that the diameter of the feeding sealing cover (16) from the top to the half thereof is larger than the diameter of the top transmission hole, and the diameter of the feeding sealing cover (16) from the half thereof to the bottom thereof is slightly smaller than the diameter of the top transmission hole, can achieve a better sealing effect, prevent dust and impurities from entering the storage box (12), and can be easily installed and disassembled, facilitating the feeding operation; The conveying cylinder (18) is designed to be cylindrical in structure, which enables the material to fall evenly and reduces the accumulation and blockage of the material during the transmission process; The feed slope (17) is of a cylindrical structure, the top of the feed slope (17) is fixedly connected to the inner side surface of the storage box (12) at a distance halfway from the top, the inner side surface and the outer side surface of the bottom of the feed slope (17) are respectively in contact with the inner side surface and the outer side surface of the top surface of the conveying tube (18), and the design of the feed slope (17) and the conveying tube (18) being connected enables the material to smoothly enter the conveying tube (18) from the storage box (12) through the feed slope (17), thereby reducing the resistance and dead angle of material transmission; The guide rail (8) has an L-shaped cross section, and two guide rails (8) are provided. The two guide rails (8) are symmetrically arranged with respect to the material storage box (12), and the openings of the two guide rails (8) are designed to be opposite to each other, which can better limit the moving direction of the material transmission plate (13) so that it can only slide along the length direction of the guide rail, thereby ensuring the accuracy and stability of the movement of the material transmission plate (13); The material transmission plate (13) is designed to slide on the guide rail (8). By driving the movable telescopic rod (11), the position of the material transmission plate (13) can be flexibly controlled, thereby achieving the blocking and opening of the bottom of the conveying cylinder (18), thereby controlling the material to enter the quantitative cylinder (4); The design of the material transmission plate (13) being slightly smaller in width than the distance between the top ends of the two guide rails (8) ensures that the material transmission plate (13) can move smoothly in the guide rails and will not cause friction or jamming with the guide rails due to being too wide; The design of placing the conveying hole close to the middle of the material transmission plate (13) in the width direction and close to one end of the material transmission plate (13) in the length direction enables the material to smoothly enter the metering cylinder (4) from the conveying cylinder (18), and at the same time, when the material transmission plate (13) moves, it can effectively block the bottom of the conveying cylinder (18) to prevent material leakage; The quantitative adjustment capsule (5) is designed to gradually increase and decrease in width from one end to the other end in an arc shape, and is fitted with the inner side of the quantitative cylinder (4). By injecting different amounts of air into the quantitative adjustment capsule (5), the effective volume inside the quantitative cylinder (4) can be changed, thereby achieving precise adjustment of the amount of material in the quantitative cylinder (4) to meet different quantitative dosing requirements; The quantitative adjustment capsules (5) are provided in plurality, and the plurality of quantitative adjustment capsules (5) are arranged equidistantly along the axial direction of the quantitative cylinder (4), so that the volume of the quantitative cylinder (4) can be adjusted more evenly, and the quantitative accuracy and stability can be improved. At the same time, it is also convenient to select a suitable number of quantitative adjustment capsules (5) for inflation adjustment according to different material quantity requirements; One end of the one-way air valve (6) is placed inside the quantitative adjustment bag (5), and the other end passes through the quantitative cylinder (4) and is placed outside and corresponds to the quantitative adjustment bag (5) one by one. This design makes it easy to inject air into the quantitative adjustment bag (5) while preventing air leakage, thereby ensuring the stability of the amount of gas in the quantitative adjustment bag (5), thereby ensuring the accuracy and reliability of the volume adjustment of the quantitative cylinder (4); The tipping sealing cover (7) is designed such that the diameter from the top to the half of the cover is slightly smaller than the diameter of the inner side surface of the metering cylinder (4), and the diameter from the half to the bottom is larger than the diameter of the inner side surface of the metering cylinder (4). This can effectively seal the bottom of the metering cylinder (4) to prevent material leakage. At the same time, under the action of the tipping telescopic rod (3), the cover can be easily opened and closed to achieve material delivery. The rotating connecting rod (1) is connected to the tipping sealing cover (7) at one end, is rotatably connected to the support plate (14) via a rotating shaft in the middle, and extends from the end connected to the tipping sealing cover (7) along the length direction of the material storage box (12) to halfway along the length direction and is then bent obliquely upward to the other end. The design can convert the telescopic movement of the tipping telescopic rod (3) into the rotation of the tipping sealing cover (7), thereby realizing the opening and closing of the bottom of the metering cylinder (4). The structure is simple and the operation is reliable. The design in which the two rotating connecting rods (1) are respectively arranged on both sides of the support plate (14) enables the tipping sealing cover (7) to be subjected to uniform force during the rotation process, thereby ensuring the stability and reliability of its movement and avoiding problems such as jamming or poor sealing due to uneven force.

[0014] The purpose is achieved by being able to store a large amount of material through the feeding component and guide the material into the metering cylinder (4), and by changing the internal volume of the metering cylinder (4) through the dosing component to achieve quantitative adjustment, thereby being able to accurately and quantitatively dosing the material.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0016] It should be further pointed out that, when describing the above specific embodiment, for the sake of simplicity and clarity, only the differences between the above specific embodiment and other embodiments are described, but those skilled in the art should know that the above specific embodiment itself is also an independent technical solution.
