A feeding roller and a cleaning roller are arranged side-by-side on the upper part of the support frame, synchronously connected by a chain. The two ends of the feeding roller and the cleaning roller are respectively fixed to the two ends of the support frame by bearings and bearing seats. Several needles are arranged on the outer circumferential walls of the feeding roller and the cleaning roller, with the needles on the outer circumferential wall of the cleaning roller contacting the outer circumferential wall of the feeding roller. A housing fixed to the support frame is located on the upper side of the feeding roller, and the lower part of the housing is connected to a shaft. The arch-breaking roller is located above the feeding roller. Both ends of the arch-breaking roller are fixed to the top of the frame via bearings and bearing seats. Several needles are set on the outer circumferential wall of the arch-breaking roller. Two flower rod screws are set on the right side of the box. The upper end of the flower rod screw is fixed to the side wall of the box, and the lower end of the flower rod screw is fixed to the quantitative control device. The quantitative control device is shaft-connected to the lower end of the right side wall of the box. A motor is located on the right side of the box and is locked to the bracket. The output shaft of the motor is connected to the arch-breaking roller and the feeding roller via a chain. It has good feeding continuity and uniform feeding. However, the feeding control range of the above device is limited, and the application scenarios are limited.

[0004] How to implement zoned material feeding based on actual production scenarios, with a wide range of applications and a large adjustable range of material feeding per unit time, has become a technical problem that needs to be solved.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0021] See Figures 1-3This utility model provides a quantitative feeding device, including a housing 1, which is hollow inside and has an open bottom. A feeding cylinder 11 is inserted through the housing 1. The inside of the feeding cylinder 11 is divided into a first feeding chamber 13 and a second feeding chamber 14 by a partition. A fine feeding assembly 2 is provided in the first feeding chamber 13. The fine feeding assembly 2 includes a fixed cylinder 21 fixed in the first feeding chamber 13. A rotatable rotating rod 22 is rotatably connected inside the fixed cylinder 21. The outer periphery of the rotating rod 22 is provided with helical blades 221 (rotating rod 22). 2. The relationship between the screw blade 221 and the screw blade 221 is the same as that of the fine screw feeding structure in the prior art, and the function is also the same. The fixed cylinder 21 is provided with a feed inlet 211 and a discharge outlet, and the feed inlet 211 and the discharge outlet are located on both sides of the fixed cylinder 21. The feeding direction of the feed inlet 211 is the same as the feeding direction of the feed cylinder 11, and the discharge direction of the discharge outlet is the same as the discharge direction of the feed cylinder 11. By rotating the rotating rod 22, the screw blade 221 is driven to rotate, thereby sending the material entering through the feed inlet 211 out through the discharge outlet.

[0022] See Figures 1-3 Specifically, the outer casing 1 is provided with a driving component 231, one end of the rotating rod 22 extends out of the outer casing 1, and the output end of the driving component 231 and the end of the rotating rod 22 extending out of the outer casing 1 are both connected to the transmission sprocket 23. A chain is provided between the two transmission sprockets 23. Through the transmission of the chain and the transmission sprockets 23, the driving component 231 can drive the rotating rod 22 to rotate.

[0023] See Figures 1-3 Preferably, the outer casing 1 is provided with an exhaust port 12 and a dust cover is provided on the exhaust port 12. When the exhaust port 12 is not in use, the dust cover can prevent external impurities from entering the interior of the outer casing 1 through the exhaust port 12.

[0024] See Figures 1-3 A rotatable rotating shaft 3 is rotatably mounted on the first feeding chamber 13. An arc-shaped gate 31 is sleeved on the rotating shaft 3. The arc-shaped gate 31 includes a curved plate-like structure and mounting plates connected to both sides of the plate-like structure. The mounting plates are all connected to the rotating shaft 3. The rotating shaft 3 can drive the arc-shaped gate 31 to rotate. The arc-shaped gate 31 is sleeved on the outside of the feeding cylinder 11. The feeding cylinder 11 is provided with an arc-shaped end that cooperates with the arc-shaped gate 31 (see...). Figure 3 By rotating the arc-shaped gate 31, the contact area between the arc-shaped gate 31 and the arc-shaped end of the feed cylinder 11 is changed, thereby changing the amount of material fed from the feed cylinder 11.

[0025] See Figures 1-3Specifically, the outer casing 1 is provided with a telescopic component 321, one end of the rotating shaft 3 extends out of the outer casing 1, and a transmission rod 32 is provided between the end of the rotating shaft 3 extending out of the outer casing 1 and the output end of the telescopic component 321 (one end of the transmission rod 32 is connected to the rotating shaft 3, and the other end of the transmission rod 32 is rotatably connected to the output end of the telescopic component 321). The transmission rod 32 can drive the rotating shaft 3 to rotate. When the telescopic component 321 is opened, the telescopic component 321 drives its rotatable connection end with the transmission rod 32 to move. Under the restriction of the rotating shaft 3, the transmission rod 32 rotates, thereby driving the rotating shaft 3 to rotate.

[0026] See Figures 1-3 Preferably, the drive component 231 is a rotary motor and the telescopic component 321 is a cylinder, which provides power to the device.

[0027] See Figures 1-3 When the material quantity is small, the fine feeding component 2 can be used to feed the material through the first feeding chamber 13. When the material quantity is large, the arc-shaped gate 31 is rotated to change the contact area between the arc-shaped gate 31 and the arc end of the feeding cylinder 11, thereby changing the material quantity fed by the feeding cylinder 11. The first feeding chamber 13 and the second feeding chamber 14 are used to feed the material simultaneously.

[0028] This utility model provides a quantitative feeding device, including a feeding cylinder with a first feeding chamber and a second feeding chamber inside. It can perform zoned feeding according to actual production scenarios, making it widely applicable. The outer shell has an exhaust port with a dust cover. When the exhaust port is not in use, the dust cover prevents external impurities from entering the outer shell through the exhaust port. The fine feeding component and the arc-shaped gate work together to adjust the feeding rate per unit time within a wide range. In summary, the beneficial effects of this utility model are: it can perform zoned feeding according to actual production scenarios, has a wide range of applications, and the feeding rate per unit time can be adjusted within a large range.
