[embodiment]
Below the preferred embodiment of model utility is described in further detail.
As shown in Figures 1 to 6, the cell culture fluid straight line peristaltic pump of a kind of embodiment, comprise Driving Stepping Motor 1, drive sprocket 2, driven sprocket 3, first moves liquid flexible pipe 7, second moves liquid flexible pipe 72, chain, first supporting plate 9 and the second supporting plate 91, described Driving Stepping Motor 1 moves for driving described drive sprocket 2, described drive sprocket 2 is rotated by driven sprocket 3 described in described chain-driving, described chain comprises chain first portion 21 and chain second portion 22, described first both sides moving liquid flexible pipe 7 are compressed by described first supporting plate 9 and chain first portion 21 respectively, described second both sides moving liquid flexible pipe 72 are compressed by described second supporting plate 91 and chain second portion 22 respectively.Chain comprises rolling wheel 4 and connects the connecting sheet 5 of adjacent rolling wheel.
Described first moves the first bayonet socket 8 and the second bayonet socket 81 that liquid flexible pipe 7 is provided with protrusion, described second moves the 3rd bayonet socket 82 and the 4th bayonet socket 83 that liquid flexible pipe 72 is provided with protrusion, described chain first portion 21 is between described first bayonet socket 8 and the second bayonet socket 81, described chain second portion 22 is between described 3rd bayonet socket 82 and the 4th bayonet socket 84, described first supporting plate 9 is provided with the first draw-in groove 92 and the second draw-in groove 93, and described second supporting plate 91 is provided with the 3rd draw-in groove 94 and the 4th draw-in groove 95.
Cell culture fluid straight line peristaltic pump can also comprise the first locking motor 10 and the second locking motor 101, described first locking motor 10 moves liquid flexible pipe 7 for driving described first supporting plate 9 to compress or departing from described first, described second locking motor moves liquid flexible pipe 72 for driving described second supporting plate to compress or depart from described second, which enhance the automation compressing and move liquid flexible pipe, such as, can reach and change the objects such as pipette sooner.
Cell culture fluid straight line peristaltic pump can also comprise supporting guide 6, and the two ends of described supporting guide 6 support described chain first portion 21 and chain second portion 22 respectively.
Described first move liquid flexible pipe 7 comprise first move liquid hose inlet 71 and first move liquid flexible pipe outlet (not marking), described second moves liquid flexible pipe 72 comprises second and moves liquid hose inlet (not marking) and second and move liquid flexible pipe outlet 73, described first and move liquid hose inlet 71 and second and move liquid flexible pipe outlet 73 and be connected with the outlet of liquid temporary storage appts. and entrance (not shown) respectively.
When cell culture fluid straight line peristaltic pump works, first locking motor 10 drives the first supporting plate 9 to move to the first pipette 7, and described first bayonet socket 8 and the second bayonet socket 81 are stuck in the first draw-in groove 92 and the second draw-in groove 93, and the first pipette 9 is made to be pressed between the first supporting plate 9 and chain first portion 21; Equally, second locking motor 101 drives the second supporting plate 91 to move to the second pipette 72, and described 3rd bayonet socket 82 and the 4th bayonet socket 83 are stuck in the 3rd draw-in groove 94 and the 4th draw-in groove 95, and the second pipette 72 is pressed between the second supporting plate 91 and chain second portion 22.
Then, Driving Stepping Motor 1 drives drive sprocket 2 to rotate, thus drive chain and driven chain 3 to rotate, as shown in Fig. 3,5 and 6, rolling wheel 4 rolls to left movement, and first moves liquid flexible pipe 7 is compressed by adjacent rolling wheel 4 and forms the solution cavity of multistage closed at both ends, along with the motion of rolling wheel 4, solution cavity also travels forward, thus achieves and quantitatively move liquid.
At synchronization, described chain first portion 21 compresses the first rolling wheel quantity of moving liquid flexible pipe 7 and chain second portion 22 and compresses second to move the rolling wheel quantity of liquid flexible pipe 72 identical, like this, second moves the liquid that liquid flexible pipe 72 is conveyed into liquid temporary storage appts., equal first and move the liquid that liquid flexible pipe 7 shifts out from liquid temporary storage appts., thus ensure that two are moved liquid flexible pipe and move the synchronous of liquid, can not cause the situations such as the negative pressure that may occur inside liquid temporary storage appts..
The quantity of the rolling wheel 4 of chain first portion 21 and chain second portion 22 is multiple, amount due to cell culture fluid is fewer, therefore, to move liquid flexible pipe vibration, move liquid pulsation and move liquid application condition responsive, adopt multiple rolling wheel 4, effectively can reduce these impacts, such as, in the present embodiment, chain first portion 21 had four rolling wheels 4 and compressed first and move liquid flexible pipe 7 any time, and so firm moving contact can be lowered to less level to the rolling wheel 4 that first moves liquid flexible pipe 7 to its impact.
Owing to moving the bayonet socket on liquid flexible pipe and the draw-in groove on supporting plate to cooperation, therefore, when moving that liquid flexible pipe is rolled takes turns 4 roll extrusion, it can not along with movement, thus ensure that and move the accurately stable of liquid.Supporting guide 6 is support chains first portion and second portion respectively, and then it is compacted to make to move liquid flexible pipe, thus ensure that and move the stable of liquid and accurately.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; some simple deduction or replace can also be made, all should be considered as belonging to the scope of patent protection that the utility model is determined by submitted to claims.
