When the material needs to be discharged, the driving part 144 drives the first support 141 and the second support 142 to rotate in opposite directions, and the transmission shaft 143 rotates. The rotating shaft drives the sealing member 132 to rotate, so that the opening of the sealing member 132 gradually approaches the feeding channel 1313 until the opening communicates with the feeding channel 1313, and at this time, the dosing assembly 13 opens the discharge port 113. When the sealing member 132 continues to rotate, the dosing member 131 rotates, and the feeding passage 1313 is always in communication with the gap 1321 for continuous feeding.

After the quantitative powder is discharged, the driving portion 144 reversely moves to reversely move the first supporting member 141, the second supporting member 142 and the transmission shaft 143, so that the sealing member 132 reversely rotates to make the gap 1321 of the sealing member 132 staggered with the feeding passage 1313 of the quantitative member 131, and at this time, the discharge port 113 is closed, and even if the sealing member 132 continues to reversely rotate, the quantitative member 131 reversely rotates, and the position of the gap 1321 is kept staggered with the feeding passage 1313.

Two adjacent helical blades 1312 form spiral conveying channel 1313, after notch 1321 of sealing member 132 is communicated with conveying channel 1313 of quantitative piece 131, sealing member 132 rotates with quantitative piece 131 synchronously, make spiral conveying channel 1313 rotate, the powder can not directly pass through the ejection of compact to the straight channel when rotating conveying channel 1313, and can carry out the windrow of certain time under conveying channel 1313's support, so can make the powder density in conveying channel 1313 more solid, avoid the powder cavity to appear, make the volume of the powder of output from conveying channel 1313 in transmission shaft 143 every round comparatively fixed. Meanwhile, when the powder flows in the material conveying channel 1313 which rotates continuously, centrifugal force is applied to the powder, so that the flow speed of the powder is increased, and the powder is prevented from being retained in the channel. Thus, the spiral conveying channel 1313 is arranged, so that stable powder discharging and accurate quantification are facilitated.

It is understood that the mounting shaft 1311 is rotatably sleeved on the transmission shaft 143 when the sealing member 132 is coupled to the transmission shaft 143, and the mounting shaft 1311 is coupled to the transmission shaft 143 when the sealing member 132 is rotatably sleeved on the transmission shaft 143. The mounting shaft 1311 may also be supported by the closure 132.

Referring to fig. 4, the outer periphery of the spiral vane 1312 is formed by a first spiral surface 1312a, a second spiral surface 1312b, an outer circular surface 1312c, and a sealing surface 1312 d. The outer circumferential surface 1312c faces the mounting shaft 1311, the first spiral surface 1312a and the sealing surface 1312d are connected to both ends of the outer circumferential surface 1312c in a first direction parallel to the axial direction of the transmission shaft 143, the sealing surface 1312d is supported by the sealing member 132, the second spiral surface 1312b extends from one end of the first spiral surface 1312a to one end of the sealing surface 1312d, the other end of the first spiral surface 1312a extends to the other end of the sealing surface 1312d, the first spiral surface 1312a of any one spiral vane 1312 and the second spiral surface 1312b of the adjacent spiral vane 1312 form a feed passage 1313, the outer circumferential surface 1312c is in sealing contact with the barrel 11, and the sealing surface 1312d can open and close the notch 1321.

One end of the first spiral surface 1312a and one end of the sealing surface 1312d are located in the same rotational direction, and the other end of the first spiral surface 1312a and the other end of the sealing surface 1312d are located in the same rotational direction, and are opposite to each other.

Preferably, referring to fig. 6, in two adjacent spiral vanes 1312, one end of the first spiral surface 1312a of one spiral vane 1312, which intersects with the second spiral surface 1312b thereof, and one end of the second spiral surface 1312b of the other spiral vane 1312, which intersects with the sealing surface 1312d thereof, are located in the same vertical plane. Therefore, all powder materials can be ensured to enter the notch 1321 along the spiral material conveying channel 1313, and cannot directly vertically enter the notch 1321 from the upper part of the notch 1321, and accurate quantification is facilitated.

Preferably, the number of the helical blades 1312 is two, and the helical angle of the two helical blades 1312 is 180 degrees. In this case, the dosing assembly 13 comprises two delivery channels 1313, and the closure 132 comprises two recesses 1321.

In some embodiments, referring to fig. 2, the inlet 112 and the outlet 113 are located at two vertical ends of the barrel 11, and the flow area of the barrel 11 gradually decreases from the end where the inlet 112 is located to the end where the outlet 113 is located. Each horizontal section of the barrel 11 is tangential to the first vertical plane.

In this case, the barrel 11 has a funnel shape, which contributes to reducing the powder voids. Wherein, each horizontal section of feed cylinder 11 all is tangent with first vertical face, explains that feed cylinder 11 has a vertical straight wall, and the powder has faster speed when falling along the straight wall, further makes piling up in the bottom that the powder can be easier, and the powder is stocky and does not have the cavity, further improves quantitative accuracy.

Further, referring to fig. 1, 3, 6 and 7, the convenient dosing device 1 further comprises a ring-shaped member 15, said ring-shaped member 15 being connected to said holding cavity 111 and being adapted to the shape of a horizontal cross-section of said cartridge 11. In this manner, the ring 15 can reinforce the strength of the cartridge 11 so that the cartridge 11 can strongly support the food can.

Further, in fig. 1, 3, 6 and 7, the convenient dosing device 1 further comprises a loosening rod 16 which is arranged on the inner wall of the ring-shaped member 15 in a protruding manner along the horizontal direction. The powder can be loosened by the loosening rod 16 while passing through the loosening rod 16, and the arrangement of the loosening rod 16 helps to improve the flowability of the powder.

Further, referring to fig. 1, the dust-proof housing 146 is located inside the ring-shaped member 15, and the loosening rod 16 is attached to the dust-proof housing 146. At this time, the connection of the powder guard 146 and the barrel 11 is achieved, and the strength of the barrel 11 is also enhanced by forming a relatively stable reinforcing structure by the powder guard 146, the loose rod 16 and the ring member 15.

The convenient proportioning device 1 that provides in the embodiment of this application, when the actual operation, with the food jar inversion in pan feeding mouth 112 department, pan feeding mouth 112 and food jar sealing connection to avoid weing or the insect pest influence, and can reduce the speed of food oxidation. The powder in the food can enters the barrel 11 and fills all parts of the material containing cavity 111. When the powder needs to be quantitatively discharged, each stirring piece 121 in the stirring assembly 12 rotates, and the quantitative assembly 13 opens the discharge port 113 so as to discharge the powder. At this moment, because each stirring piece 121 rotates along two opposite directions at least, can fully stir the powder, make the powder fully flow, when quantitative subassembly 13 opened discharge gate 113, the powder of fully flowing can be ejection of compact smoothly, can also avoid the powder cavity to appear simultaneously, reduces the clearance between the powder, helps guaranteeing accurate ration.
