As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.
The present invention first provides a pinch valve head, please refer to fig. 1, fig. 2 and fig. 3, which includes a valve head 10; a pair of first side surfaces 1 of the valve head 10 are respectively provided with branch pipe grooves 11, and two through openings of each branch pipe groove 11 are respectively positioned on a pair of second side surfaces 2 of the valve head 10; the distance between the two branch pipe grooves 11 and the nearest part of the central shaft is 52.4 mm-69.4 mm; the first end face 3 of the valve head 10 is further provided with at least two valve plate through holes 12, and each branch pipe groove 11 is communicated with at least one valve plate through hole 12.
The branch hoses 110 are mounted into the branch pipe grooves 11 from the opening sides of the branch pipe grooves 11 on the two first side surfaces 1, so that the distance between the two branch pipe grooves 11 in the valve head 10 does not need to consider the reserved space for hose mounting in the design process, and can be reduced as much as possible within the allowable range of other conditions, namely, the distance between the valve plate through holes 12 communicated with the branch pipe grooves 11 is reduced;
since the pinch valve 30 is mounted in the valve head 10 through the valve plate through hole 12, the distance between the valve plate through holes 12 is reduced, that is, the distance between the pinch valves 30 is reduced, so that the effect of reducing the overall occupied space of the pinch valve 30 is achieved; and the distance between the pinch valves 30 is reduced, so that the length of the hose 100 between the two pinch valves 30 is correspondingly reduced, thereby improving the manufacturability and sanitation of the equipment and further improving the quality of the output.
In addition, since the size of the driving member 31 of the pinch valve 30 is generally larger than the diameter of the hose 100, by designing the distance between the two branch pipe grooves 11 at the nearest position to the central axis to be 52.4 mm-69.4 mm, the distance between the two branch pipe grooves 11 can be reduced as much as possible while the installation space of the driving member 31 is reserved, so as to ensure that each pinch valve 30 can be normally installed, and the installation is relatively compact and occupies a small space.
Because the openings of the two branch pipe grooves 11 are opposite, after the two branch hoses 110 are installed in the branch pipe grooves 11, the whole moving freedom degree of the hose 100 can be limited through the limiting effect of the inner walls of the two branch pipe grooves 11 on the branch hoses 110 positioned in the branch pipe grooves, so that the hose 100 can only move along the length direction of the branch pipe grooves 11, and the branch hoses 110 are prevented from shaking along the radial direction.

because each valve plate through hole 12 can be internally provided with one pinch valve 30, the valve head 10 is internally provided with four valve plate through holes 12, and two parts of each branch pipe groove 11 are communicated with one valve plate through hole 12, so that two branch hoses 110 in each branch pipe groove 11 correspond to one pinch valve 30, the opening and closing of the corresponding branch hoses 110 can be respectively controlled through each pinch valve 30, and the accurate control on the opening and closing of the four branch hoses 110 can be realized.
Preferably, the distance between the two valve plate through holes 12 corresponding to the same branch pipe groove 11 is at least 60mm, so as to reserve an installation space for the corresponding pinch valve 30, and avoid subsequent abnormal installation caused by interference of the driving member 31 of the pinch valve 30.
In a second aspect, the present invention provides a pinch valve assembly for controlling the opening and closing of a flexible tube 100, as shown in fig. 1 and 2, comprising a base plate 20, a plurality of pinch valves 30, and the valve head 10; the valve head 10 is fixedly arranged on one side of the substrate 20, the valve plate through hole 12 faces the substrate 20, the pinch valves 30 are fixedly arranged on the other side of the substrate 20 and correspond to the valve plate through holes 12 one by one, and one end of each pinch valve 30 penetrates through the substrate 20 and the valve plate through hole 12 to the branch pipe groove 11.
Because each valve block through-hole 12 all sets up in same valve head 10 for the pinch valve valves of this application only need the single installation to accomplish being connected between valve head 10 and the base plate 20 in the equipment process, compare and need install each valve head 10 to base plate 20 one by one among the prior art, reduced the installation step, increased the installation effectiveness.
In the embodiment shown in fig. 2 and 4, the pinch valve 30 includes a driving member 31 and a valve plate 32, the driving member 31 is fixed on the base plate 20, and the valve plate 32 penetrates through the base plate 20 and the valve plate through hole 12 to the branch pipe groove 11.
The driving member 31 can drive the valve sheet 32 to reciprocate along the central axis direction of the valve sheet through hole 12, so that the branch hose 110 in the branch pipe groove 11 is squeezed or loosened by the valve sheet 32, and the branch hose 110 can cut off and flow.
In the embodiment shown in fig. 5, the valve head 10 is further provided with notches 141 corresponding to the valve plate through holes 12 one to one, the notches 141 are communicated with the branch pipe grooves 11 along the central axis of the valve plate through holes 12, and the notches 141 are further communicated with the valve plate through holes 12; the valve head 10 is further provided with grooves 142 corresponding to the notches 141 one by one, and the grooves 142 are formed in one side of the branch pipe groove 11 far away from the notches 141 and communicated with the branch pipe groove 11;

In addition, compared with the case where the groove 142 is not formed, the valve plate 32 abuts against the inner wall of the branch pipe groove 11, so that the branch pipe groove 11 cannot be completely blocked; through seting up slot 142 in this application for valve block 32 can move the top of valve block 32 and the diapire laminating butt of slot 142 when the axis direction motion process along valve block through-hole 12, and valve block 32 stops branch pipe groove 11 completely this moment, can cut off branch hose 110 completely through the extrusion in order to guarantee that valve block 32 can increase pinch valve 30's reliability.
In the embodiment shown in fig. 1, the proximal end faces of any two adjacent driving members 31 are parallel to each other; the driving pieces 31 are cuboids, and the side end faces, close to the two adjacent driving pieces 31, are arranged in parallel, so that the driving pieces 31 can be closely arranged, gaps among the driving pieces 31 are reduced, and the overall size of the pinch valve group is reduced.
The driving member 31 may be a power assembly such as a motor or a cylinder. In the embodiment shown in fig. 6, the driving member 31 is a cylinder having a length of 60mm and a width of 45 mm; the driving member 31 comprises an extension spring 311, a housing 312 and a bottom supporting member 313, wherein the housing 312 is fixedly arranged on the bottom supporting member 313, one end of the extension spring 311 is fixedly arranged with the bottom supporting member 313, the other end of the extension spring is fixedly arranged with the valve sheet 32, the valve sheet 32 is positioned inside the housing 312 and is completely abutted and slidably connected with the inner wall of the housing 312, and a through hole is formed in the surface of the housing 312 and is used for being communicated with the air pump;
when the hose 100 needs to be blocked, the air pump starts to fill air into the cylinder, and the air pushes the valve plate 32 to move in the direction away from the driving piece 31 by overcoming the pulling force of the extension spring 311 until the hose 100 is clamped;
conversely, when the hose 100 needs to be flowed through, the air pump stops supplying air, the valve plate 32 moves to the direction close to the driving member 31 under the pulling force of the extension spring 311 to return, and the hose 100 is flowed through.
In addition, the length direction of the cylinder is the length direction of the branch pipe groove 11, and the width direction of the cylinder is the length direction of the main pipe groove 13;
