Description

Technical Field

[0001] The present invention relates to the technical field of peristaltic pumps, and particularly to a bilateral six-pump-head peristaltic pump. Background Art

[0002] A peristaltic pump transfers fluid by alternately squeezing and releasing the peristaltic end. It is like using fingers to pinch and squeeze a hose filled with fluid. As the fingers move forward and squeeze, the fluid in the tube is moved forward. Similarly, the rollers in the peristaltic pump play the same role and work in cooperation with different groups of pump heads. However, there is still a defect in the existing peristaltic pumps during operation.

[0003] In the prior art, the patent number of the authorized publication (announcement): CN214837033U, "A Small Dual-channel Peristaltic Pump Head". In this utility model, a small dual-channel peristaltic pump head is disclosed, which includes a pump head body, a dual-channel pipe joint, a roller assembly, and a housing. A mounting hole is provided in the middle of one side wall of the pump head body. An installation cavity is provided on one side of the mounting hole, and the roller assembly is provided on one side of the installation cavity. The roller assembly includes a roller frame, a jack provided in the middle of one side wall of the roller frame, a guide wheel provided on the outer peripheral side wall of the roller frame, a limiting roller provided between the guide wheels, and a roller shaft installed in the guide wheel and the limiting roller. The beneficial effects are as follows: Through the design of the dual-channel pipe joint, pump tube, limiting roller, and guide wheel, the peristaltic pump head can not only achieve dual-channel pumping, with a large pumping volume and improved pumping efficiency of the peristaltic pump head, but also effectively prevent the pump tube from deviating during pumping, avoid damage to the pump tube, improve the service life of the peristaltic pump head, and has good practicability.

[0004] During the operation of the above device, through the design of the dual-channel pipe joint, pump tube, limiting roller, and guide wheel, the peristaltic pump head can not only achieve dual-channel pumping, with a large pumping volume and improved pumping efficiency of the peristaltic pump head, but also effectively prevent the pump tube from deviating during pumping, avoid damage to the pump tube, improve the service life of the peristaltic pump head, and has good practicability. However, when in use, directly placing the double tubes on the same pump head easily causes insufficient extrusion of the peristaltic tube.

[0005] In the prior art, in the "multi-channel peristaltic pump head" with the authorized publication (announcement) number: CN218030533U, the conveying hose is placed in the first connecting groove 2 of the pump body 1, and the mounting plate 4 is placed in two opposite U-shaped limiting plates 3. When the mounting plate 4 is pressed downward, the trapezoidal limiting block 10 contracts back into the telescopic groove 9. When the top of the mounting plate 4 leaves the trapezoidal limiting block 10, it is inserted out under the push of the spring 13 to limit the mounting plate 4. Rotate the threaded rod 5 to lower the pressing block 6, so that the extrusion pump head 8 can press the hose against the pressing plate 6. When it is necessary to disassemble and replace a certain channel, only the pressing plate 6 of this channel needs to be removed, and the whole peristaltic pump does not need to be stopped, and the replacement without stopping the machine can be realized. However, when the elasticity becomes loose, it is easy to cause insufficient extrusion of the peristaltic tube, resulting in intermittent delivery of the conveyed material;

[0006] In addition, in the prior art, in the "peristaltic pump head with multiple channels" with the authorized publication (announcement) number: CN209444540U, the problem of a single channel in the peristaltic pump during the fluid transmission process is solved. Different fluids can be transmitted through multiple channels at the same time, and the structure is simple, the design is reasonable, and it is easy to implement and suitable for popularization. The technical solution of the present invention will be further described in detail below through the drawings and embodiments. However, when in use, assembling multiple pump heads on one side of the motor is likely to cause excessive rotational torque on the shaft of the motor and is not convenient for stable support and use; Summary of the Invention
