Description

Technical Field

[0001] This utility model relates to the field of peristaltic pump technology, and in particular to a peristaltic pump unloading and ejection mechanism. Background Technology

[0002] A peristaltic pump is a common type of liquid pump. When in use, the roller assembly on the pump head is driven to continuously squeeze the tubing, thereby propelling the liquid in the tubing to flow. It features high precision, low shear force, good sealing, and ease of use, so it is often used in medical, chemical, and biological fields.

[0003] To improve production efficiency and protect the sterile environment on site, peristaltic pumps are gradually moving towards automation. In the current technology, the loading and unloading of peristaltic pump tubing is done manually. However, the overall size of peristaltic pumps is small, the internal space of the casing is very limited, and the various components are tightly connected, which greatly increases the difficulty of loading and unloading tubing. Therefore, the manual efficiency is very low in actual operation, and it is also not conducive to protecting the sterile environment of the production site. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a peristaltic pump unloading and ejection mechanism that can achieve automated ejection and control the ejection distance with significantly improved precision.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: 1. A peristaltic pump unloading tube ejection mechanism, characterized in that: it includes a motor, a sensing base and a mounting base, a bushing is fitted on the output shaft of the motor, the inner side of the bushing is threadedly connected to the outer side of the output shaft, a push rod is fitted on the bushing, the push rod is inserted into the push rod hole on the mounting base and extends out of the push rod hole, a limiting hole is provided on the push rod, a limiting rod on the bushing passes through the limiting hole, the limiting hole is used to limit the rotation of the bushing and the advance of the push rod, and a sensor is provided on the sensing base.

[0006] In the above technical solution, the limiting hole is an elongated hole.

[0007] In the above technical solution, the upper part of the top rod hole is provided with a relief groove for accommodating the limiting rod.

[0008] In the above technical solution, the top rod has sensing holes on both sides of its body, and the positions of the sensing holes correspond to those of the sensors.

[0009] In the above technical solution, one end of the mounting base is mounted on the motor, and the other end is mounted on the peristaltic pump back plate through the bolt fixing holes on both sides.

[0010] In the above technical solution, a return spring is provided between the push rod and the bushing, and the return spring is disposed in the push rod and fitted onto the end of the bushing.

[0011] In the above technical solution, the mounting base is provided with an observation port in the middle.

[0012] In summary, the advantages of this utility model over traditional technologies are as follows: the ejection mechanism of this utility model uses a motor-driven screw structure to eject the ejector rod, which ejects the pipe support clamped in the peristaltic pump. The bushing and the output shaft are connected by threads, and the limiting rod restricts the rotation of the bushing. This screw-driven structure greatly improves the accuracy and can accurately control the ejection distance of the pipe support, combined with mechanized operation. Attached Figure Description
