Description

Technical Field

[0001] The present invention relates to the technical field of pinch valves, and more specifically, to a multi-channel pinch valve that can be synchronously adjusted. Background Art

[0002] In applications in industries such as medicine, biology, and the food industry, it is often necessary to use a flexible hose to transport liquids and be able to control the on-off of the pipeline to achieve the control of the liquid passage; at the same time, the pipelines used are generally sterilized, and aseptic operation is required during the installation of the pipeline and the control of the liquid transportation through the pipeline. Since the flexible hose can be clamped outside the pipe without contacting the liquid inside the pipe to achieve on-off control, the pinch valve can meet the above requirements. Common means for controlling the on-off of the flexible hose include electromagnetic pinch valves, which use electromagnetic force to lock the valve head to clamp the flexible hose. This method can control one pipeline or multiple pipelines simultaneously. However, when controlling multiple pipelines, multiple pipelines controlled by one valve head can only be opened or closed simultaneously. If multiple pipelines need to be opened and closed in sequence, multiple solenoid valves have to be used, which will cause problems such as a large number of solenoid valves in the system, large occupied space, and high costs.

[0003] Using a motor to drive a cam valve head can also control the sequential on-off of multiple flexible hoses simultaneously. The principle is to use a rotating wheel with a circular segment cut off, which squeezes a flexible hose at different angles (generally evenly distributed) in the circumferential direction. When the direction of the circular segment turns to the position of a certain flexible hose, that flexible hose is opened, and other flexible hoses are in a closed state due to being squeezed. However, this method is only applicable to controlling the sequential opening and closing of flexible hoses, and the opening and closing mode is single. In industries such as medicine, biology, food, and chemical engineering, the opening and closing of liquid passages are not the same. For example, in the production of different chemical liquid materials, the types of raw materials used are different, and the liquid raw materials to be added in a single process may be one or more. The above multi-channel pinch valve has a single function, and the number of flexible hoses opened at one time is fixed, which causes great limitations to the application scenarios of the multi-channel pinch valve. In view of this, we propose a multi-channel pinch valve that can be synchronously adjusted. Summary of the Invention

[0004] The purpose of the present invention is to provide a multi-channel pinch valve that can be synchronously adjusted to solve the technical problem of the single function of the multi-channel pinch valve.

[0005] To solve the above technical problems, the present invention provides the following technical solution: A multi-channel pinch valve that can be synchronously adjusted, including a base, on which an installation round seat is fixedly provided. On the installation round seat, a number of pinch valve mechanisms are arranged in an annular equidistant structure. A hose mechanism is provided on the pinch valve mechanism, and a rotation mechanism is provided at the center position of the installation round seat. The pinch valve mechanism includes a function disc and an adjustment disc. Both the function disc and the adjustment disc are rotatably arranged on the installation round seat. At one end of the function disc close to the adjustment disc, two centripetal grooves are symmetrically opened. At one end of the adjustment disc close to the function disc, an opening and closing guide groove is opened. Two pinch components are arranged in the gap between the function disc and the adjustment disc. The pinch components are slidably connected to the centripetal grooves, and both of the two pinch components are movably connected to the opening and closing guide groove. A number of the adjustment discs and the output end of the rotation mechanism are both meshed and connected through a gear ring component. The opening and closing guide groove includes two V-shaped guide grooves, and both ends of the two V-shaped guide grooves are connected through a delay arc groove. The function disc and the installation round seat are in plug-in fit through a plug-in component A, and the function disc and the adjustment disc are in plug-in fit through a plug-in component B. Through the structural design of the pinch valve mechanism of the present invention, the output end of the rotation mechanism can drive a number of gear ring components and a number of adjustment discs to rotate. And when the plug-in component A is plugged into the installation round seat and the plug-in component B is separated from the adjustment disc, the output end of the rotation mechanism can drive the adjustment disc to rotate relative to the function disc, so that one end of the pinch component moves in the opening and closing guide groove. When one end of the pinch component moves in the delay arc groove, the position of the pinch component remains unchanged and clamps the hose mechanism, and the hose mechanism is in a closed state. When one end of the pinch component moves on the V-shaped guide groove, the opposite movement of the two pinch components is controlled, thereby controlling the opening and closing of the pinch valve mechanism. When and only when the plug-in component A is separated from the installation round seat and the plug-in component B is plugged into the adjustment disc, the rotation of the adjustment disc can drive the adjustment disc and the function disc to rotate as a whole, and the opening and closing state of the pinch valve mechanism is kept unchanged. Furthermore, 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 component in the corresponding delay arc groove can be adjusted to control the opening and closing sequence and quantity of each pinch valve mechanism, realizing the multi-functional application of the multi-channel pinch valve, improving the application range of the multi-channel pinch valve, and solving the technical problem of the single function of the multi-channel pinch valve.

[0016] Preferably, the rotating mechanism includes a gear and a motor. The gear is disposed at the center of the circular cavity. A plurality of side tooth rings are meshed with the gear.

The connecting shaft penetrates into the installation cavity and is fixedly connected to the output shaft of the motor.

[0017] The beneficial effects of the present invention are:

[0018] 1. Through the structural design of the pinch valve mechanism, the output end of the rotating mechanism can drive a number of gear ring assemblies and a number of adjusting discs to rotate. When the plugging component A is plugged into the mounting round seat and the plugging component B is disengaged from the adjusting disc, the output end of the rotating mechanism can drive the adjusting disc to rotate relative to the functional disc, causing one end of the pinch component to move within the opening and closing guide groove. When one end of the pinch component moves within the delay arc groove, the position of the pinch component remains stationary and clamps the hose mechanism, and the hose mechanism is in the closed state. When one end of the pinch component moves on the V-shaped guide groove, the opposite movement of the two pinch components is controlled, thereby controlling the opening and closing of the pinch valve mechanism. When and only when the plugging component A is disengaged from the mounting round seat and the plugging component B is plugged into the adjusting disc, the rotation of the adjusting disc can drive the integral rotation of the adjusting disc and the functional disc, and the opening and closing state of the pinch valve mechanism is kept unchanged. Furthermore, according to the opening and closing sequence and quantity of different processes in the application scenario, the initial positions of the ends of each pinch component on the corresponding delay arc groove can be adjusted to control the opening and closing sequence and quantity of each pinch valve mechanism, realizing the multi-functional application of the multi-channel pinch valve, expanding the application range of the multi-channel pinch valve, and solving the technical problem of the single function of the multi-channel pinch valve.

[0019] 2. The plugging slot B of the present invention is used for plugging and cooperating with the plugging component B. The rotation radian of the V-shaped guide groove provided in the present invention is an integer multiple of the gap radian between two adjacent plugging slots A. The number of several through holes is equal to the number of plugging slots B. When it is necessary to adjust the opening and closing sequence and quantity of several pinch valve mechanisms according to different processes, the initial positions of the ends of each pinch component on the corresponding delay arc groove need to be adjusted. The initial positions of the ends of the pinch components on one or more pinch valve mechanisms applied to one process are the same. The initial positions of the ends of the pinch components on one or more pinch valve mechanisms applied to its adjacent process need to differ from the initial positions of the ends of the pinch components on the pinch valve mechanisms of this process by at least the rotation radian of one V-shaped guide groove. After the position adjustment of the ends of the pinch components on the corresponding delay arc groove is completed, the plugging component A can still be plugged into the plugging slot A, and the plugging component B can still be plugged into the plugging slot B.

[0020] 3. Through the structural design of the plug-in component A and the plug-in component B, the present invention enables the rotary adjustment screw block and the adjustment shaft to rotate in the displacement guide groove, causing the guide ball block to move on the displacement guide groove, resulting in the connecting ring moving relative to the limit post on the ring groove. When the plug-in column B is inserted into the plug-in groove B, the connecting ring moves to disengage from the linkage rod. Under the contraction elastic force of the spring, the plug-in column A moves into the moving groove and disengages from the plug-in groove A. At this time, there is still a certain gap between the linkage 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 first contacts the linkage rod. During the movement of the connecting ring, the plug-in column A disengages from the moving groove and is inserted into the plug-in groove A, and the spring stretches, realizing the synchronous adjustment of the plug-in component A and the plug-in component B, which is convenient for adjustment. Among them, the initial state of all the pinch valve mechanisms is that the plug-in column B is inserted into the plug-in groove B, while the plug-in column A is in the moving groove and disengages from the plug-in groove A.

[0021] 4. Through the further design of the displacement guide groove, the present invention enables the movement of the guide ball block on part of the threaded groove to limit the movement distance of the connecting ring on the ring groove, facilitating the synchronous adjustment of the plug-in component A and the plug-in component B. And when the guide ball block moves to the limit arc groove, the limit arc groove has a limiting effect on the guide ball block, eliminating the need to set an additional fixing structure for the insertion state of the plug-in component A and the plug-in component B, making the adjustment of the plug-in component A and the plug-in component B more convenient.

[0022] 5. Through the structural design of the hose mechanism, the present invention enables the hose mechanism to rotate as the function disc rotates, preventing the rotation of the transfer pipe when adjusting the opening and closing sequence and quantity of each pinch valve mechanism by controlling the initial positions of the end parts of each pinch component on the corresponding delay arc groove. Triangular auxiliary strips are fixedly provided at both ends of the cross plate, and trapezoidal grooves are opened at the adjacent ends of the two U-shaped clamp blocks. When the two U-shaped clamp blocks clamp the soft rubber tube, the clamping cavity formed by the two trapezoidal grooves is exactly adapted to the overall shape formed by the cross plate and the two auxiliary strips, avoiding large-angle folding of the soft rubber tube when the U-shaped clamp blocks clamp the soft rubber tube, and making part of the inner surface of the soft rubber tube tightly fit with the cross plate and the two auxiliary strips when clamping, ensuring the closing effect and reducing the occurrence of water leakage.

With the above settings of the present invention, when one end of the pipe clamping assembly 35 moves on the V-shaped guide groove 341, the other end of the pipe clamping assembly 35 moves on the corresponding centripetal groove 33, so that the two pipe clamping assemblies 35 move towards each other, thereby controlling the opening and closing of the pipe clamping valve mechanism 3; when one end of the pipe clamping assembly 35 moves in the delay arc groove 342, the other end of the pipe clamping assembly 35 remains stationary on the corresponding centripetal groove 33, and the pipe clamping assembly 35 remains stationary and clamps the hose mechanism 4.

[0051] In an embodiment of the present invention, one end of the mounting circular seat 2 is provided with a plurality of rotating grooves 21 in an annular equidistant structure. A plurality of plugging grooves A22 are provided in the rotating grooves 21 in an annular equidistant structure. The other end of the mounting circular seat 2 is provided with a plurality of through holes 23 at positions corresponding to the plurality of rotating grooves 21. A circular cavity 24 is formed in the mounting circular seat 2. Both ends of the circular cavity 24 are communicated with the rotating groove 21 and the through hole 23 respectively.

When it is necessary to adjust the opening and closing sequence and quantity of a plurality of pinch valve mechanisms 3 according to different processes, it is necessary to adjust the initial positions of the end parts on one side of each pinch component 35 in the corresponding delay arc grooves 342. The initial positions of the end parts on one side of the pinch component 35 on one or more pinch valve mechanisms 3 in one process are the same. The initial positions of the end parts on one side of the pinch component 35 on one or more pinch valve mechanisms 3 applied to its adjacent process need to differ from the initial positions of the end parts on one side of the pinch component 35 in the corresponding delay arc grooves 342 of this process by at least the rotation radian of one V-shaped guide groove 341, so that after the position adjustment of the end part on one side of the pinch component 35 in the corresponding delay arc groove 342 is completed, the plugging component A36 can still be plugged with the plugging groove A22, and the plugging component B37 can still be plugged with the plugging groove B391.

[0053] In an embodiment of the present invention, the pinch component 35 includes a U-shaped clamp block 351. The clamp block 351 is slidably connected with the centripetal groove 33 through a slider 352. A fixed shaft 353 is fixedly arranged at one end of the clamp block 351 away from the centripetal groove 33. Both fixed shafts 353 and the opening and closing guide groove 34 are movably connected through a movable ring 354. Among them, in the initial state of the present invention, all the movable rings 354 are in the communication positions of the corresponding V-shaped guide groove 341 and the delay arc groove 342.

[0054] In an embodiment of the present invention, the gear ring assembly 30 includes a side gear ring 301. The side gear ring 301 is disposed in the circular cavity 24. A rotating tube 302 is fixedly provided on the side gear ring 301. One end of the rotating tube 302 is rotatably connected to the through hole 23, and the other end of the rotating tube 302 is fixedly connected to the adjusting disc 32.

[0055] In an embodiment of the present invention, the plug-in assembly A 36 includes a plurality of plug-in posts A 361. The plurality of plug-in posts A 361 are respectively movably disposed on a plurality of movable grooves 382. The plug-in posts A 361 are in plug-in fit with the plug-in slots A 22. A linkage rod 362 is fixedly provided at one end of the plug-in post A 361 close to the annular groove 381. The linkage rod 362 penetrates into the annular groove 381 and is in movable fit with the plug-in assembly B 37. The linkage rod 362 is movably connected to the function disc 31. A spring 363 is sleeved on the linkage rod 362. Both ends of the spring 363 are of a gradually decreasing structure, and both ends of the spring 363 are respectively fixedly connected to the movable groove 382 and the plug-in post A 361.

[0056] In an embodiment of the present invention, the plugging component B37 includes a connecting ring 371 movably disposed on the annular groove 381. A plurality of moving holes 372 are formed in the connecting ring 371 at an equal interval in a circular shape. The cross-section of the connecting ring 371 is in a trapezoidal structure. The linkage rod 362 is movably matched with the connecting ring 371. An adjusting shaft 373 is movably connected to one of the moving holes 372. A plurality of groups of displacement guide grooves 374 are formed in the adjusting shaft 373 at an equal interval like a planet. Each group of the adjusting shafts 373 includes a plurality of them arranged at an equal interval in a circular shape. A guide ball block 375 is movably connected to the displacement guide groove 374. The guide ball block 375 is fixedly connected to the corresponding moving hole 372. One end of the adjusting shaft 373 away from the through hole 23 penetrates out of the functional disc 31 and is fixedly provided with an adjusting screw block 376. The adjusting shaft 373 is rotatably connected to the functional disc 31. A limiting column 377 is movably connected to the remaining moving holes 372. The limiting column 377 is fixedly connected to the annular groove 381. A plurality of plugging columns B378 are formed in an equal interval in a circular shape at one end of the connecting ring 371 close to the plugging groove B391. The plurality of plugging columns B378 are respectively plugged and matched with the plurality of plugging grooves B391. Through the structural design of the plugging component A36 and the plugging component B37 in the present invention, when the adjusting screw block 376 is rotated, the adjusting shaft 373 and the displacement guide groove 374 rotate, so that the guide ball block 375 moves on the displacement guide groove 374, causing the connecting ring 371 to move relative to the limiting column 377 on the annular groove 381. When the plugging column B378 is plugged with the plugging groove B391, the connecting ring 371 moves to disengage from the linkage rod 362. Under the contraction elastic force of the spring 363, the plugging column A361 moves into the moving groove 382 and disengages from the plugging groove A22. At this time, there is still a certain gap between the linkage rod 362 and the inner edge surface of the annular groove 381. When the connecting ring 371 moves to drive the plugging column B378 to disengage from the plugging groove B391, the inclined surface of the connecting ring 371 first contacts the linkage rod 362. During the movement of the connecting ring 371, the plugging column A361 disengages from the moving groove 382 and is plugged with the plugging groove A22, and the spring 363 is stretched, realizing the synchronous adjustment of the plugging component A36 and the plugging component B37, which is convenient for adjustment. Among them, all the pinch valve mechanisms 3 are initially in the state where the plugging column B378 is plugged with the plugging groove B391, and the plugging column A361 is in the moving groove 382 and disengaged from the plugging groove A22.

[0057] The displacement guide groove 374 includes a partial threaded groove 3741, and limiting arc grooves 3742 are communicated at both ends of the partial threaded groove 3741. Through the further design of the displacement guide groove 374 in the present invention, the movement distance of the connecting ring 371 on the annular groove 381 is limited by the movement of the guiding ball block 375 on the partial threaded groove 3741, which is convenient for the synchronous adjustment of the plug-in assembly A36 and the plug-in assembly B37.

[0061] A method for using a multi-channel pinch valve that can be synchronously adjusted includes the following steps:

[0062] S1: Adjust the opening and closing sequence and quantity of the pinch valve mechanism 3 according to different processes of the application scenario;

[0063] S1.1: Adjustment of one or more pinch valve mechanisms 3 in the first process;

[0064] Rotate the adjustment screw block 376 applied to one or more pinch valve mechanisms 3 in the first process. The adjustment shaft 373 rotates with the displacement guide groove 374, so that the guide ball block 375 moves on the displacement guide groove 374, causing the connecting ring 371 to move relative to the limit post 377 on the ring groove 381, so that the corresponding connecting ring 371 drives the insertion column B378 to disengage from the insertion slot B391. The inclined surface of the connecting ring 371 first contacts the linkage rod 362. During the movement of the connecting ring 371, the insertion column A361 disengages from the movable slot 382 and is inserted into the insertion slot A22;

[0065] The output shaft of the motor 53 is controlled to rotate by an external control mechanism. The gear 51 drives a plurality of side tooth rings 301 to rotate. The rotation of the side tooth ring 301 in the first process drives the corresponding rotating pipe 302 and the adjustment disc 32 to rotate, so that the movable ring 354 in the first process rotates by the rotation radian of a V-shaped guide groove 341 in the delay arc groove 342;

[0066] The insertion column B378 on the remaining pinch valve mechanisms 3 is inserted into the insertion slot B391. The corresponding rotating pipe 302 drives the adjustment disc 32 and the function disc 31 to rotate as a whole. The position of the corresponding movable ring 354 on the corresponding delay arc groove 342 remains unchanged;

[0067] S1.2: Adjustment of one or more pinch valve mechanisms 3 in the second process;

[0068] Rotate the adjustment screw block 376 applied to one or more pinch valve mechanisms 3 in the second process, so that all the insertion column B378 on the first process and the second process are disengaged from the insertion slot B391, and all the insertion column A361 are disengaged from the movable slot 382 and inserted into the insertion slot A22;

[0069] The rotation of the output shaft of the motor 53 is controlled by an external control mechanism. The rotation of the side gear rings 301 in the first process and the second process drives the corresponding rotating pipes 302 and the adjusting disks 32 to rotate, so that the movable rings 354 in the first process and the second process rotate by a rotation radian of a V-shaped guide groove 341 in the delay arc groove 342; the positions of the corresponding movable rings 354 on the remaining pinch valve mechanisms 3 remain unchanged on the corresponding delay arc grooves 342.

[0070] S1.3: Refer to the steps of S1.1 and S1.2: After adjusting the pinch valve mechanisms 3 on all the remaining processes, it is completed.

[0071] S2: Connect the hose mechanisms 4 on all processes to the external pipelines one by one.

[0072] S3: During use, the rotation of the output shaft of the motor 53 is controlled by an external control mechanism, so that the adjusting disks 32 on all the pinch valve mechanisms 3 rotate relative to the corresponding functional disks 31. The movable rings 354 rotate in the delay arc grooves 342. The movable ring 354 in the first process first enters the corresponding V-shaped guide groove 341 to move. When the movable ring 354 moves to the eccentric end of the V-shaped guide groove 341, the pinch tube assembly 35 in the first process is separated from the hose mechanism 4, and the hose mechanism 4 in the first process is in an open state. After that, the movable ring 354 in the first process moves to the connection point of the V-shaped guide groove 341 and another delay arc groove 342, and the movable ring 354 in the second process moves to the entry end of the V-shaped guide groove 341. By analogy, it can be known that the pinch valve mechanisms 3 on all processes open and close in sequence.

[0073] S4: The embodiments disclosed in the present invention are preferred embodiments, but not limited thereto. Those of ordinary skill in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the present invention, they are within the protection scope of the present invention.
