The pump body includes a pump chamber and a pump cover assembly, an elastic hose 17 is arranged inside the pump chamber, and the pump cover assembly is arranged on the top of the pump chamber. The rotating mechanism includes a rotating tube pressing assembly and a rotating drive assembly, one end of the rotating tube pressing assembly is connected to the output end of the rotating drive assembly, and the other end of the rotating tube pressing assembly is an inclined end and extends into the pump chamber. The lifting mechanism includes a guide connection assembly and a lifting drive assembly, one end of the guide connection assembly is connected to the side of the pump chamber, and the other end of the guide connection assembly is connected to the output end of the lifting drive assembly. When the pipeline pump is working, the lifting drive assembly drives the guide connection assembly to rise, and drives the rotating tube pressing assembly to approach the pump cover assembly, the rotating drive assembly drives the rotating tube pressing assembly to swing in a circle, and cooperates with the pump cover assembly to squeeze the elastic hose 17 to realize material conveying. After completing a single material metering and conveying, the lifting drive assembly drives the guide connection assembly to descend, and drives the rotating tube pressing assembly away from the pump cover assembly, and the rotating drive assembly drives the rotating tube pressing assembly to rotate to the initial conveying position.

[0027] In this embodiment, by arranging the pump body, the rotating mechanism and the lifting mechanism on the mounting plate 4, a compact pipeline pump main structure is formed. Specifically, an elastic hose 17 is arranged inside the pump chamber, and the pump cover assembly is arranged on the top of the pump chamber; one end of the rotating tube pressing assembly is connected to the output end of the rotating drive assembly, and the other end is an inclined end and extends into the pump chamber to realize the hose extrusion; one end of the guide connection assembly is connected to the side of the pump chamber, and the other end is connected to the output end of the lifting drive assembly, so as to realize the connection between the pump chamber and the lifting mechanism.

After completing the single material metering and conveying, the lifting drive assembly drives the guide connection assembly to descend, and drives the pump chamber and the rotating tube pressing assembly away from the pump cover assembly, and the rotating drive assembly drives the rotating tube pressing assembly to rotate to the initial conveying position. The pipeline pump of this embodiment lowers the rotating tube pressing assembly away from the pump cover after each fluid filling, disengages the squeezing of the elastic hose 17, and at the same time, the rotating tube pressing assembly is reset to the initial position before filling through the rotating drive assembly.

The cone 14 is nested at the inclined end of the eccentric shaft 2 and is located below the elastic hose 17. Driven by the rotary motor 1, the eccentric shaft 2 drives the cone 14 to swing in a circular undulation, and cooperates with the pump cover 18 to squeeze the elastic hose 17 to realize the delivery of the fluid.

[0032] like Figure 1 As shown, in this embodiment, the bearing includes a tapered roller bearing 6 and a first deep groove ball bearing 8 which are arranged in sequence.

The pull rod 19 is connected to the output end of the lifting motor 21, one end of the support plate 20 is connected to the pull rod 19, and the other end of the support plate 20 is nested outside the bearing seat 7. Driven by the lifting motor 21, the pull rod 19 drives the support plate 20 to rise and fall, thereby realizing that the pump chamber and the rotating pressure tube assembly are close to or away from the pump cover 18.

[0035] like Figure 1 As shown, in this embodiment, a guide sleeve 3 is provided between the bearing seat 7 and the mounting plate 4, and the bearing seat 7 is reciprocatedly lifted and lowered along the guide sleeve 3 to improve the accuracy of the lifting and lowering displacement of the bearing seat 7.

[0036] At the moment of each filling completion, the lifting motor 21 pulls the rod 19 and the support plate 20 to move downward together, and the rotating motor 1 and the bearing seat 7 are driven by the support plate 20 to deviate downward along the guide sleeve 3 until the cone 14 no longer squeezes the elastic hose 17 together with the pump cover 18. After the rotating motor 1 drives the eccentric shaft 2 and the cone 14 to return to the initial position before filling, the lifting motor 21 pushes the rod 19 and the support plate 20 to move upward together, driving the rotating motor 1, the bearing seat 7, the eccentric shaft 2 and the cone 14 to deviate upward along the guide sleeve 3, and the cone 14 and the pump cover 18 squeeze the elastic hose 17 together, and repeat a new filling operation.

[0038] In this embodiment, after each fluid filling, the cone 14 moves downward immediately to disengage the squeeze on the elastic hose 17, and at the same time, the cone 14 is reset to the initial position before filling through the rotating motor 1. In this way, the initial position of the cone 14 is the same during the next filling, that is, the cone 14 is reset to zero each time it is filled, thereby achieving continuous filling in the same phase and greatly improving the accuracy of repeated filling.
