Multiple through holes for being used to be inserted into crushing block, each crushing block are inserted into corresponding through hole and expose outside the edge of turntable
Face.
Deep groove ball bearing is equipped at the cooperation of above-mentioned crushing block and turntable, through hole on the outer ring of deep groove ball bearing and turntable
Edge is engaged by clamping, and the inner ring and crushing block of deep groove ball bearing are mating.
Above-mentioned driver is usually servomotor, and with gear reduction unit.
Crushing block is inserted into the through hole on turntable, when driver driving disc rotates, crushing block squeezes soft delivery pipe
Tube wall, with the rotation of turntable, two neighboring crushing block is realized quantitative by squeezing, unclamping the fluid in soft delivery pipe
The conveying of fluid；Since through hole is uniformly distributed along turntable edge inner circumferential, user can be according to use demand, in suitable position
The through hole put plugs crushing block, and turntable is carried out decile；And when use demand changes, crushing block is directly removed from turntable,
It is inserted into other suitable vias, you can change the shape of entire rotor, it is easy to operate, reach by changing rotor
Shape adjusts the purpose of extrusion capacity and rate of extrusion.
As the preferred embodiment of the utility model, the crushing block is cylinder.Cylindrical press block can be squeezed preferably
It presses, release soft delivery pipe, the conveying of fluid in soft delivery pipe of being more convenient for, while bearing that can be preferably with through hole is inserted
Connect cooperation.
As the preferred embodiment of the utility model, the number of openings is at least 6 ~ 12.In the routine use of peristaltic pump
In, more commonly used is to plug two to four crushing blocks, i.e., is halved rotor, trisection or the quartering.
As the further preferred embodiment of the utility model, the number of openings is 9.It is preferred that number of openings is 9, it can
Rotor is subjected to trisection to plug three crushing blocks, two idle through holes are retained between two neighboring crushing block；It can also
Six crushing blocks are plugged according to demand, and an idle through hole is retained between two neighboring crushing block；By changing idle through hole
Quantity, so as to change the length for the soft delivery pipe that is not squeezed.
The utility model compared with prior art, has the following advantages that：
The utility model peristaltic pump, as rotor, a certain number of crushing blocks is inserted using a turntable for being inserted with crushing block
Enter the through hole on turntable, when driver driving disc rotates, crushing block squeezes the tube wall of soft delivery pipe, with turning for turntable
Dynamic, two neighboring crushing block realizes the conveying of dosed fluid by squeezing, unclamping the fluid in soft delivery pipe；Due to through hole
It being uniformly distributed along turntable edge inner circumferential, user can plug crushing block according to use demand in the through hole of suitable position,
Turntable is subjected to decile；And when use demand changes, crushing block is directly removed from turntable, is inserted into other suitable vias
In, you can change the shape of entire rotor, it is easy to operate, reach and adjust extrusion capacity by changing the shape of rotor and squeeze
Go out the purpose of rate.
