A base 2 is provided on the frame 1, a cylindrical groove 201 is provided on the base 2, and a through hole 202 connected to the cylindrical groove 201 is provided at the bottom of the base 2. The column 3 is located in the cylindrical groove 201 and is slidably connected to its inner wall. A plurality of die holes 301 are provided in a ring array around the axis of the column 3, and each die hole 301 corresponds to a feeding station, an extrusion station, an alternative station and a unloading station arranged in sequence along the screwing direction of the column 3. The support frame 4 is connected to the frame 1. A hydraulic cylinder 5 is arranged on the support frame 4. The hydraulic cylinder 5 drives and connects the push rod 6. The end of the push rod 6 away from the cylinder of the hydraulic cylinder 5 is connected to the pressure detector 7. The output end of the pressure detector 7 is connected to the gland 8. A connecting frame 9 is arranged on the push rod 6. The connecting frame 9 is connected to the push plate 10. The gland 8 and the push plate 10 are respectively located above the die holes 301 corresponding to the extrusion station and the blanking station. The driving assembly includes a second motor 104. The second motor 104 drives the column 3 to rotate so as to rotate the loading station to the extrusion station, the extrusion station to the alternative station, the alternative station to the blanking station and align it with the through hole 202, and the blanking station to the loading station. The quantitative feeding mechanism is connected to the frame 1. The quantitative feeding mechanism includes a bracket 12, a storage barrel 15, a pushing assembly and a control assembly. A support plate 13 is arranged on the bracket 12. A gravimeter 14 is arranged on the support plate 13. The gravimeter is electrically connected to the control assembly. The storage barrel 15 is located inside the bracket 12, the side wall of the storage barrel 15 is slidably connected to the bracket 12, and the bottom of the storage barrel 15 is connected to the detection end of the gravimeter 14. A feeding pipe 16 is arranged at the bottom of the storage barrel 15, and the feeding pipe 16 is coaxial with the die hole 301 corresponding to the feeding station, and the outer diameter of the feeding pipe 16 is smaller than the inner diameter of the die hole 301. The pushing component is connected to the storage barrel 15, and the pushing component drives the raw materials in the storage barrel 15 into the feeding pipe 16 in the working state, and the control component controls the connection of the pushing component. The quantitative feeding mechanism quantitatively feeds the die hole 301 corresponding to the feeding station in the working state. The pushing component includes an auger 17 and a third motor 18. The auger 17 is located in the storage barrel 15 and extends into the feeding pipe 16, and the auger 17 is slidably connected to the inner wall of the feeding pipe 16. The third motor 18 is connected to the storage barrel 15 and drives the auger 17 to rotate. The third motor 18 is an AC motor. When the material is not being fed, the third motor 18 drives the auger to rotate in the opposite direction to mix the raw materials in the mixing barrel.

[0026] In this embodiment, the gravimeter 14 records the total weight of the storage barrel 15 and the raw materials therein, and then the third motor 18 drives the auger 17 to rotate and discharge the raw materials along the discharge pipe 16 into the die hole 301 corresponding to the feeding station. When the total weight is reduced by the set weight difference, the auger 17 stops, and the second motor 104 drives the column 3 to rotate, and rotates the die hole 301 corresponding to the feeding station to the die hole corresponding to the extrusion station. Then the hydraulic cylinder 5 presses down the push rod 6, and the pressure cover 8 presses down the raw materials and shapes them.

The biscuits fall into the discharge hopper 203 and slide along the discharge hopper onto the conveyor belt 102. The formed biscuits are transferred through the conveyor belt 102 to prevent the biscuits from accumulating under the through hole 202 and causing secondary downward pressure to crush the biscuits.
