Description

Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to a quantitative feeding device for food processing. Background Technology

[0002] Food production requires mixing multiple raw materials, which necessitates the use of a quantitative feeding device to add the raw materials quantitatively into the mixing equipment. Existing technologies typically employ a spiral vane to draw raw materials into a mixing device. The rotation angle of the vane is proportional to the flow rate of raw materials it draws. However, the amount of raw materials drawn by the vane is not precise. Furthermore, the continuous conveying of raw materials by the vane makes it impossible to determine the output volume and quantitatively discharge the materials. Therefore, there is an urgent need to provide a quantitative feeding device for food processing. Summary of the Invention

[0014] The beneficial effects are as follows: the discharge cylinder, metering cylinder, outer spiral blade, and inner spiral blade rotate synchronously. The raw material is rolled up on the inner walls of the discharge cylinder and metering cylinder due to gravity. The spiral directions of the outer and inner spiral blades are opposite, and they roll up the raw material in opposite directions. The inner spiral blade rolls the raw material along the inner wall of the metering cylinder. Then, the raw material passes through the spiral groove and accumulates in the gap between the metering cylinder and the discharge cylinder. The rotation of the outer spiral blade hinders the movement of the raw material on the inner wall of the discharge cylinder. The raw material fills the gap between the metering cylinder and the discharge cylinder. The discharge cylinder, metering cylinder, outer spiral blade, and inner spiral blade rotate in opposite directions. The outer spiral blade rolls the raw material and discharges it from the end of the discharge cylinder. The rotation of the inner spiral blade hinders the movement of the raw material in the metering cylinder, preventing subsequent raw material from passing through the spiral groove and into the metering cylinder. This allows for precise metering of the raw material. The precise metering and rolling of the raw material by the outer and inner spiral blades with opposite spiral directions ensures accurate discharge and is very convenient to use.

[0027] In use, firstly, the raw material is poured into the inside of the collecting cover 13, storage box 14, and discharge box 15. The raw material fills the inside of the collecting cover 13, storage box 14, and discharge box 15. Power component 12 is connected to the power supply and drives the vertical rod 2 to rotate, causing the threaded ring 23 to move upward along the axial direction of the vertical rod 2. The threaded ring 23, fixed plate 24, and lifting plate 27 move upward synchronously along the axial direction of the vertical rod 2. The position of the lifting plate 27 is offset from the position of the discharge port. Power component 26 is connected to the power supply and drives the center rod 36 to rotate clockwise.

The spiral direction of the inner spiral blade 38 and the spiral direction of the outer spiral blade 37 are the same. In the opposite direction, the outer screw 37 rotates and rolls the raw material from right to left, filling the gap between the discharge cylinder 31 and the metering cylinder 32. When the raw material accumulates on the inner wall of the discharge cylinder 31 and cannot enter the spiral groove 39, the quantitative measurement of the raw material is completed. The power component 16 is connected to the power supply and drives the center rod 36 to rotate counterclockwise. The inner screw 38 rotates and rolls the raw material on the inner wall of the metering cylinder 32 from right to left, preventing the raw material from entering the metering cylinder 32. The outer screw 37 rotates and rolls the raw material from left to right. The outer screw 37 rolls the raw material accumulated in the gap between the discharge cylinder 31 and the metering cylinder 32. The raw material is discharged from one end of the discharge cylinder 31 and falls into the discharge frame 33. The quantitative raw material is discharged through the discharge frame 33, completing the quantitative discharge of the raw material. In use, the power component 34 is connected to the power supply to drive the rotating disk 41 to rotate at high speed, so that the rotating disk 41, the extrusion ring 42 and the two protruding blocks rotate synchronously at high speed. The protruding blocks continuously collide with the impact block 411, pushing the impact block 411, the piston sleeve 49 and the impact block 410 to move synchronously on the inner wall of the piston cylinder 44. The impact block 410 continuously hits the force plate 47, causing the force plate 47 to vibrate. The vibration of the force plate 47 is transmitted to the gathering cover 13, the storage box 14 and the discharge box 15, causing the raw material to vibrate on the inner wall of the gathering cover 13, the storage box 14 and the discharge box 15, preventing the raw material from accumulating on the inner wall of the gathering cover 13 and facilitating the discharge of the raw material.
