Embodiment, belongs to the scope of protection of the invention.
The present invention provides a kind of peristaltic pump of roller phase variable, to realize that flexible pipe is loosened in automation, and with low cost, knot
Structure is succinct.
Fig. 1 a-1b show a kind of peristaltic pump of roller phase variable, including：
Active roller group 1, at least one passive roller group 2, active roller frame 3, passive turning rolls 4 and can rotating electricity
Machine 5, wherein：
Illustrated with reference to Fig. 1 a-1b：
The active roller group 1 includes at least one roller shaft (not identifying) and is socketed on the roller of the roller shaft, described
Passive roller group 2 includes at least one roller shaft 6 and is socketed on the roller of the roller shaft；
The active roller group 1 includes the active roller frame 3, and the active roller frame 3 is socketed on the main shaft of motor 5
On；
The passive roller group 2 includes the passive turning rolls 4, and the passive turning rolls 4 is socketed on by the support of bearing 41
On the main shaft of motor 5；
Preferably, in Fig. 1 a, the active roller group 1 of the peristaltic pump includes a roller, and the passive roller group 2 is set
One is equipped with, the passive roller group 2 includes a roller, but is not limited thereto.
It should be noted that it is described can the motor of rotating can select stepper motor.The passive turning rolls 4 is by rolling
Dynamic bearing is supported on the main shaft of stepper motor 5, is not connected directly with main shaft, main axis will not drive passive roller
Frame；Active roller frame 4 is installed on the main shaft of motor 5.
Referring to Fig. 1 b, permanent magnet 8 is provided between the frame 7 of the passive turning rolls 4 and the peristaltic pump.The permanent magnetism
The effect of iron 8 is to increase damping between passive turning rolls 4 and frame 3；Passive turning rolls 4 is set to go to certain position (such as every time
Stop position) when and frame 3 between produce a suction, prevent passive turning rolls 4 improper when because of frictional force
Effect is rotated with active roller frame 4, it is ensured that the reliability of the transposition action of active roller.Accordingly, the material of the roller shaft 6
, can be by attraction for permeability magnetic material.
Beaten what motor was rotated forward under liquid operating mode, the phase difference of the active roller group 1 and the passive roller group 2 is
180°；
When the motor reversal, the phase difference of the active roller group 1 and the passive roller group 2 is less than preset angle
Degree, the predetermined angle is the active roller group 1 and passive 2 groups of the roller flexible pipe track away from the peristaltic pump simultaneously
Angle.
The frame 3 of the peristaltic pump of the roller phase variable is shown in Fig. 1 a, is pressed from both sides between the frame 3 and stepper motor 8
There is installing plate 9；Code-disc 10 is installed on the rear shaft of stepper motor 8.On the corresponding installing plate of the code-disc 10, equipped with photoelectric transfer

It should be noted that bar-shaped trough is provided with the code-disc 10, to determine the Angle Position residing for active roller frame.
As shown in Fig. 2 when pump is in and beats liquid status：Active roller frame 3 and the laminating of passive turning rolls；Now such as Fig. 2
View location, the motor 5 is rotated clockwise, then active roller frame 3 is stirred passive turning rolls 4 and rotated clockwise together；Now
Two roller groups are in 180 ° of phase difference, can normally beat liquid；
When needing to stop and fluid path is circulated, the motor 5 is inverted, and drives active roller frame 3 to invert, now passive rolling
Wheel carrier 4 is likely to be at any Angle Position, may together be inverted due to the drive of frictional force, but as long as when going to stop position its
Roller shaft 12 is just attracted by magnet 8, produces damping；When active roller frame 3 continues to rotate, it is ensured that active roller frame 3 and quilt
Dynamic turning rolls 4 is separated；
As shown in figure 3, when needing to complete the action of loose tube before charge and discharge rubber lined hose, the upper active roller frame 3 stops above-mentioned
Only and make fluid path circulate in the case of, continue 360 ° of rotate counterclockwise, the motor 5 persistently invert, active roller frame 3 reversion
Start to contact with passive turning rolls 4 again after certain angle, now active roller group 1 is reduced to the passive phase difference of roller group group 2
30 ° (angle is not limited to), the predetermined angle is the active roller group 1 and the passive roller group 2 simultaneously away from institute
The angle of the flexible pipe track of peristaltic pump is stated, as illustrated, the active roller group 1 is abutted against with the passive roller of roller group 2
Together, phase difference reduces, and when stopping roller all in there is no roller on the outer flexible tube track of flexible pipe track.Now at roller
In the position shown in Fig. 3, (flexible pipe is on work circle charge and discharge rubber lined hose, and the semicircle that the side of frame 7 is identified in Fig. 1 a is work
Circle) it is very convenient.Code-disc 10, the photoelectricity when active roller frame goes to above-mentioned stop position are housed on the rear shaft of the motor 5
Sensor obtains signal, and controller makes motor 8 stop operating；Then complete the action of loose tube；
When needing fluid path to disconnect, the motor 5 is rotated forward, and the active roller frame 3 is rotated clockwise, now due to described
The magneticaction of magnet 8, the passive turning rolls 4 can't be driven by frictional force；When active roller frame 3 and passive turning rolls 4
During laminating, the phase of active roller group 1 and passive roller group 2 returns to 180 ° again, now according to the roller of conventional peristaltic pump
Flexible pipe is compressed, stops liquor charging.
Preferably, in order to coordinate above-mentioned peristaltic pump to include pump case, the pump case cornerite is 180 ° but not limited to, and is schemed
4-5 shows that the active roller group 1 of peristaltic pump is provided with a roller, passive roller group 2 be provided with two rollers beat liquid and
Loosen the working condition and structure during flexible pipe；
Fig. 6-7 shows that the active roller group 1 of peristaltic pump is provided with two rollers, and passive roller group 2 is provided with two rollings
Take turns the working condition and structure when beating liquid and loosening flexible pipe；
Fig. 4-7 structure and operation principle illustrates and its diagram that it is no longer repeated referring to Fig. 1-3.
In summary：
The peristaltic pump of the roller phase variable of the embodiment of the present invention, is provided with active roller group and passive roller group group, bag
The passive roller of passive rotation under including in the active roller group of active rotation under motor drives and being driven in the active roller group
Group；That is, active roller group includes active roller frame, and passive roller group includes passive turning rolls；Active roller frame and the motor
Main shaft is connected；Passive turning rolls is by bearings on the electric machine main shaft：
During normal work, the active roller frame is rotated by motor and can stir passive turning rolls and rotate together, now
Phase difference between active roller group and passive roller group is 180 °, can continuously beat liquid, realize the material transferring work(of peristaltic pump
Energy；When needing to loosen flexible pipe and lead to fluid path, or when changing flexible pipe, motor reversal drives the reversion of active roller frame, the quilt
Permanent magnet is provided between the frame of dynamic turning rolls and the peristaltic pump, due to there is suction between passive turning rolls and roller shaft
It is not struck, starts to contact with passive turning rolls again after now active roller frame reversion certain angle, active roller group and quilt
Dynamic roller group phase difference is reduced to predetermined angle, the predetermined angle be the active roller group with the passive roller group simultaneously
The angle of flexible pipe track away from the peristaltic pump；There is no roller on flexible pipe track, be convenient for changing flexible pipe.
The peristaltic pump structure compact, realizes the function of the good switching of fluid path, can rotating motor rotate forward and
Under the drive of reversion, phase difference is variable between realizing peristaltic pump roller, completes to loosen the action of flexible pipe, not only controls simply, and into
