Description

Technical Field

[0001] The invention relates to the technical field of pinch valves, and more particularly to a synchronously adjustable multi-channel pinch valve. Background Art

[0002] In the application of medicine, biology, food industry and other industries, it is often necessary to use hoses to transport liquids and control the on and off of pipelines to achieve control of liquid passages; at the same time, the pipelines used are generally sterilized, and aseptic operation is required during the installation of pipelines and the control of pipeline liquid transportation. Because the hose can be clamped outside the tube without contacting the liquid in the tube to achieve on-off control, the clamp valve can meet the above needs. The commonly used means to control the on and off of the hose is the electromagnetic clamp valve, which uses electromagnetic force to lock the valve head and clamp the hose. This method can control the on and off of one pipeline or multiple pipelines at the same time, but when controlling multiple pipelines, multiple pipelines controlled by one valve head can only be on or off at the same time. If multiple pipelines need to be on and off in sequence, multiple solenoid valves can only be used, which will cause a large number of solenoid valves in the system, occupy a large space and high cost.

[0003] Using a motor to drive a concave wheel valve head can also control the sequential opening and closing of multiple hoses at the same time. The principle is to use a rotating wheel with a circular gap cut out to squeeze a hose at different angles in the circumferential direction (generally evenly distributed). When the direction of the circular gap turns to the position of a certain hose, the hose is opened, and other hoses are closed due to being squeezed. However, this method is only applicable to controlling the sequential opening and closing of hoses, and the opening and closing mode is single. The control opening and closing of liquid passages in medicine, biology, food, chemical industry and other industries are not the same. For example, the production of different chemical liquid materials uses different types of raw materials, and the liquid raw materials that need to be added in a single process may be one or more. The above-mentioned multi-channel pinch valve has a single functionality and a certain number of hoses opened at a single time, which causes great limitations to the application scenarios of the multi-channel pinch valve. In view of this, we propose a synchronously adjustable multi-channel pinch valve. Summary of the invention

[0015] The beneficial effects of the present invention are: 1. The present invention adopts a structural design of the clamp valve mechanism so that the output end of the rotating mechanism can drive a plurality of gear ring components and a plurality of adjusting discs to rotate, and when the plug-in component A is plugged into the mounting round seat and the plug-in component B is disconnected from the adjusting disc, the output end of the rotating mechanism can drive the adjusting disc to rotate relative to the functional disc, so that one end of the clamp component moves in the opening and closing guide groove. When one end of the clamp component moves in the delay arc groove, the position of the clamp component remains stationary and clamps the hose mechanism, and the hose mechanism is in a closed state. When one end of the clamp component moves on the V-shaped guide groove, the opposite movement of the two clamp components is controlled. When the plug-in assembly A is disengaged from the mounting round seat and the plug-in assembly B is plugged into the adjusting disc, the rotation of the adjusting disc can drive the adjusting disc and the functional disc to rotate as a whole, while the opening and closing state of the pinch valve mechanism remains unchanged. Then, according to the opening and closing sequence and quantity of different processes in the application scenario, the initial position of one end of each pinch assembly in the corresponding delay arc groove can be adjusted to control the opening and closing sequence and quantity of each pinch valve mechanism, thereby realizing the multifunctional application of the multi-channel pinch valve, improving the application scope of the multi-channel pinch valve, and solving the technical problem of the single function of the multi-channel pinch valve.

[0016] 2. The plug-in slot B of the present invention is used for plug-in cooperation with the plug-in component B. The rotation arc of the V-shaped guide groove set in the present invention is an integer multiple of the gap arc of two adjacent plug-in slots A. The number of through holes is equal to the number of plug-in slots B. Since the opening and closing sequence and number of the clamping valve mechanisms need to be set according to different processes, it is necessary to adjust the initial position of one side end of each clamping component in the corresponding delay arc groove. The initial position of one side end of the clamping component on one or more clamping valve mechanisms of one process is the same as the initial position of the corresponding delay arc groove. The initial position of one side end of the clamping component on one or more clamping valve mechanisms of the adjacent process in the corresponding delay arc groove needs to differ from the initial position of one side end of the clamping component in the corresponding delay arc groove of the process by at least one rotation arc of the V-shaped guide groove, so that after the position adjustment of one side end of the clamping component on the corresponding delay arc groove is completed, the plug-in component A can still be plugged with the plug-in slot A, and the plug-in component B can still be plugged with the plug-in slot B.

[0017] 3. The present invention adopts the structural design of the plug-in component A and the plug-in component B, so that the rotating adjustment screw block, the adjusting shaft and the displacement guide groove rotate, so that the guide ball block moves on the displacement guide groove, causing the connecting ring to move relative to the limit column on the ring groove. When the plug-in column B is plugged into the plug-in groove B, the connecting ring moves to disengage from the connecting rod. Under the contraction elastic force of the spring, the plug-in column A moves into the active groove and disengages from the plug-in groove A. At this time, there is still a certain gap between the connecting rod and the inner edge surface of the ring groove. When the connecting ring moves to drive the plug-in column B to disengage from the plug-in groove B, the inclined surface of the connecting ring contacts the connecting rod first. During the movement of the connecting ring, the plug-in column A is disengaged from the active groove and plugged into the plug-in groove A. The spring is stretched, thereby realizing the synchronous adjustment of the plug-in component A and the plug-in component B, and the adjustment is convenient. Among them, the initial state of all the clamping valve mechanisms is that the plug-in column B is plugged into the plug-in groove B, and the plug-in column A is in the active groove and disengaged from the plug-in groove A.

[0018] 4. The present invention further designs the displacement guide groove, so that the guide ball block is movable on a part of the threaded groove to limit the movable distance of the connecting ring on the ring groove, which is convenient for the synchronous adjustment of the plug-in component A and the plug-in component B. When the guide ball block moves to the limiting arc groove, the limiting arc groove has a limiting effect on the guide ball block, and there is no need to set an additional fixing structure for the plug-in state of the plug-in component A and the plug-in component B, which makes the adjustment of the plug-in component A and the plug-in component B more convenient.

[0019] 5. The present invention adopts a structural design of the hose mechanism so that the hose mechanism rotates with the rotation of the functional disc, thereby preventing the rotating tube from being twisted when adjusting the initial position of one side end of each clamping assembly at the corresponding delay arc groove to control the opening and closing sequence and number of each clamping valve mechanism. Auxiliary strips with a triangular structure are fixed at both ends of the horizontal plate, and trapezoidal grooves are opened at the proximal ends of the two U-shaped clamping blocks, so that when the two U-shaped clamping blocks clamp the soft rubber tube, the clamping cavity formed by the two trapezoidal grooves is just adapted to the overall shape formed by the horizontal plate and the two auxiliary strips, thereby avoiding the large-angle folding of the soft rubber tube when the U-shaped clamping blocks clamp the soft rubber tube, and making the inner surface of the soft rubber tube part tightly fit with the horizontal plate and the two auxiliary strips when clamping, thereby ensuring the closing effect and reducing the occurrence of water leakage.
