When the mixing tube 15 is completely below the feeding tube 19, the feeding tank 20 enters the material tank 3 to ensure that the solution will not splash out of the mixing tube 15.

Please refer to Fig. 3-4, Fig. 6, Fig. 9-11, the negative pressure suction mechanism includes a toothed ring 40 fixedly installed on the inner wall of the support bucket 2, and the mixing tube 15 is rotatably mounted with the toothed ring 40 Engaged gear 36, the end of the gear 36 away from the mixing tank 1 is fixed with a hollow ring 37, and the inner wall of the hollow ring 37 is provided with a guide groove 38; The piston disc 24 in 15, the end of the piston disc 24 away from the mixing bucket 1 is fixed with a No. 1 movable rod 34, and the end of the No. 2 movable rod 45 away from the support sleeve 46 is fixed with a sealing ring 44, and A second protrusion 47 is fixed on the side wall of the second movable rod 45, and the piston disc 24 is connected with the conduction mechanism.

Furthermore, in the feeding process, in order to ensure the mixing effect of raw materials, the solution placed in the mixing tube 15 can be controlled to hedge against the solution delivered by the material tank 3, so as to achieve the effect of rapid mixing, and the guide groove 38 is set in a wave shape , and there are four wavy grooves, the troughs of each wavy groove are located on the same horizontal plane, and the peaks of each wavy groove increase in turn. In the initial state, the No. 1 protrusion 35 is located at the trough position of the guide groove 38, so that The No. 1 movable rod 34 and the piston disc 24 are located at the end of the stroke towards the mixing tube 15. When the mixing tube 15 is filled with raw materials in the first material tank 3, the solution will be located in the middle of the mixing tube 15 under the action of gravity. position, the mixing tube 15 continues to rotate, and drives the gear 36 to move. Since the gear 36 meshes with the gear ring 40, the drive gear 36 itself rotates. The gear 36 also drives the hollow ring 37 to rotate, and drives the guide groove 38 to move.

Further speaking, the limit block 39 can be divided into four parts, and each part is set in a fan-shaped column with an included angle of 90°, and the protrusion amount of each limit block 39 increases sequentially, so the limit block 39 is a circumferential step In the initial state, the No. 2 spring 29 is in a compressed state, and the limit block 39 with the smallest protrusion is located directly below the fixed wheel 33. At this time, the No. 1 protrusion 35 is located in the trough where the height difference between the two peaks is the largest. , the No. 3 spring 31 is in a compressed state, so that the end of the hollow rod 30 away from the limit block 39 abuts against the piston disc 24, and under the action of the connecting rod 32, the two sliding rods 27 are controlled to move towards the end of the stroke in the direction of approaching each other.

At this time, the feeding pipe 19 starts feeding synchronously, so that the two solutions are hedged. When the No. 1 protrusion 35 moves to the peak position, the distance between the sliding rods 27 is the largest, and the supporting rods 28 moves to the matching position of the limiting hole 26, the second spring 29 is elastically released, and drives the support rod 28 into the limiting hole 26.

Preferably, in order to ensure that the solution will not be pushed due to the influence of pressure when the piston disc 24 is reset, it is necessary to ensure that the mixing tube 15 remains in a conduction state all the time. The position hole 26 is engaged to ensure that the relative position of the hollow rod 30 and the piston disc 24 will not change, so that the air inlet hole is always located below the piston disc 24, and when the runner moves to abut against the inner wall of the mixing tube 15, the two The two sliding rods 27 move toward each other, and control the support rod 28 to break away from the limit hole 26, thereby compressing the second spring 29.
