[0052] Working principle: When working, the driving source on the mixing tank 1 is started, and the driving source is driven through the transmission member after it works, so that the first reciprocating screw 706 in the fixed frame 3 rotates synchronously, and the first reciprocating screw 706 in the fixed frame 3 rotates, so that the first wedge block 701 connected to its surface moves. During this process, the driving source on the mixing tank 1 will continue to stir the material in the mixing tank 1. When the first wedge block 701 moves upward and contacts the second wedge block 703 in the fixed block 702, the first wedge block 701 will abut against the second wedge block 703 to move. When the second wedge block 703 moves, it will drive the baffle 704 to move synchronously, so that the connecting spring 705 connected between the baffle 704 and the fixed block 702 is deformed, and when the second wedge block 703 moves, the connecting cylinder 802 connected to the other end of the rotating rod 803 will move through the action of the rotating rod 803, and the movement of the connecting cylinder 802 drives the moving rod 801 moves out from one end of the second reciprocating screw 501 until the second bevel gear 805 connected to one end of the moving rod 801 meshes with the first bevel gear 804 connected to the first reciprocating screw 706. When the first reciprocating screw 706 rotates to drive the first wedge block 701 to move, it will also drive the first bevel gear 804 to rotate. The second bevel gear 805 engaged by the first bevel gear 804 rotates, and the second bevel gear 805 rotates to drive the moving rod 801 to rotate. After the moving rod 801 rotates, it drives the second reciprocating screw 501 connected to its outside to rotate synchronously. The rotation of the second reciprocating screw 501 can make the screw sleeve 502 connected to its surface move. When the screw sleeve 502 moves, it will drive the driving rod 503 connected to its inside to move synchronously. When the driving rod 503 moves under the drive of the screw sleeve 502, it will also be affected by the wave groove 602 on the fixed plate 601, so that the driving rod 503 moves up and down at the same time.

[0053] When the driving rod 503 moves downward, it will contact the contact plate 904 on the liquid supply cylinder 901 and synchronously push the contact plate 904 to move toward the liquid supply cylinder 901. At this time, the support spring 905 connected between the contact plate 904 and the liquid supply cylinder 901 will be squeezed, so that the support spring 905 will be deformed, and after the contact plate 904 moves, it will push the piston 902 in the liquid supply cylinder 901 to move synchronously through the push rod 903. After the piston 902 moves, it will squeeze the distribution liquid inside the liquid supply cylinder 901, so that the distribution liquid can flow into the mixing tank through the first one-way tube 101 on the liquid supply cylinder 901. 1. After the extrusion is completed, the driving rod 503 will move under the action of the screw sleeve 502 and separate from the contact plate 904. At this time, the contact plate 904 will be reset under the action of the support spring 905. During the reset of the contact plate 904, the piston 902 inside the liquid supply cylinder 901 moves synchronously, so that the liquid in the liquid dispensing tank 2 can be drawn into the liquid supply cylinder 901 again through the second one-way tube 102, so as to continue the next liquid supply. During the movement of the driving rod 503, multiple conveying mechanisms can be triggered in sequence to work, thereby realizing the batch-by-batch liquid supply operation of the mixing tank 1.

[0055] When it is necessary to synchronously adjust the positions of multiple limit plates 111, the extension plate 402 on the extension rod 401 is rotated so that the extension plate 402 is rotated to the pull plate 124, and the bolt 403 at the corresponding pull plate 124 is rotated so that the bolt 403 is connected to the corresponding pull plate 124. At this time, by pulling the extension plate 402, the multiple pull plates 124 connected to it can be synchronously pulled to move synchronously, thereby achieving the purpose of synchronously adjusting multiple limit plates 111 and achieving the purpose of adjusting the liquid supply volume of multiple liquid supply cylinders 901, which is more convenient to operate.
