Abstract

The invention provides a sliding shoe auxiliary squeezing device of a peristaltic pump. The sliding shoe auxiliary squeezing device comprises a squeezing sliding block and a driving mechanism used fordriving the squeezing sliding block to slide. The end, far away from the driving mechanism, of the squeezing sliding block is provided with a squeezing mechanism for implementing arc-shaped squeezingon a liquid delivery pipe in the cross-section direction of the liquid delivery pipe. The invention further discloses the peristaltic pump. The peristaltic pump comprises the sliding shoe auxiliary squeezing device of the peristaltic pump. According to the sliding shoe auxiliary squeezing device of the peristaltic pump, the driving mechanism drives the squeezing sliding block to slide, so that the squeezing mechanism on the squeezing sliding block implements arc-shaped squeezing on the liquid delivery pipe in the cross-section direction of the liquid delivery pipe. During arc-shaped squeezing, squeezing force of the squeezing mechanism on the liquid delivery pipe increases gradually and then decreases gradually. The squeezing process has the transitivity. Pulses generated during squeezingare reduced. damage to rigid squeezing on the liquid delivery pipe is avoided. A substance in the liquid delivery pipe is also protected against damage.

Description

【Technical field】 [0001] The invention relates to the field of fluid delivery equipment, in particular to a sliding shoe pair extruding device of a peristaltic pump and the peristaltic pump. 【Background technique】 [0002] Peristaltic pump is a kind of volumetric special pump widely used in chemical industry, food, medicine and other fields. Peristaltic pump is usually divided into finger-shaped peristaltic pump and disc-shaped peristaltic pump. The working surface of the cylindrical structure is cylindrical, and the pump core is cylindrical. A series of rollers are installed on its cylindrical surface, and an elastic soft pump tube is placed in the working space formed together with the pump casing. When the pump core rotates, the pump tube is squeezed to make the pump tube form continuous peristalsis and propel the liquid flow; finger-type peristaltic pump The working space is linear, and a series of finger-shaped sliders arranged in a straight line are pushed by the cam g...
