[0036] The present application will be described in more detail in the following paragraphs with reference to the accompanying drawings. The advantages and features of the present application will be more apparent according to the following description and claims. It should be noted that the drawings are very simplified and all use non-precise proportions, only for the purpose of facilitating and clearly assisting the description of the embodiments of the present application. Figure 1 And Figure 2 The pipe clamping device of the present application is introduced.

[0037] As Figure 1 And Figure 2 shown, the present application proposes a pipe clamping device, comprising a rack 100, a control module and at least one pressing plate 200 and a plurality of pipe clamping units arranged on the rack 100. The pipe clamping unit corresponds to the hose of the filling branch one by one. The pipe clamping unit comprises a driving mechanism 310 and a driving rod 320, and the driving rod 320 and the pressing plate 200 have a gap for the hose of the filling branch to pass through, and the driving mechanism 310 is used to drive the driving rod 320 to approach or move away from the pressing plate 200 to clamp or release the hose of the filling branch. The control module is used to independently control each driving mechanism 310 to adjust the time of driving the driving rod 320 to approach or move away from the pressing plate 200 by the driving mechanism 310.

[0038] The present application sets up a plurality of pipe clamping units, each of which corresponds to a hose of a filling branch, and realizes clamping and releasing of the hose through the driving mechanism 310 and the driving rod 320. The control module independently controls each driving mechanism 310, so that each pipe clamping unit can independently adjust the clamping and releasing time as needed, thereby realizing independent control of the hoses of a plurality of filling branches. This design solves the problem of difficult independent control of a plurality of filling branches in the prior art, and improves the filling precision and flexibility.

[0039] In one of the embodiments, the control module can be a programmable logic controller (PLC), which can independently control the start-stop and timing of each drive mechanism 310 by taking advantage of the multi-channel independent control capability of the PLC, for example, the S7-1200 series or S7-1500 series PLC of Siemens can be used. In other embodiments, the control module can also be a microcontroller (MCU), for example, the STM32H743 of STMicroelectronics or the C2000 series MCU of Texas Instruments can be used.

[0040] In one of the embodiments, the rack 100 includes a base plate 110, a vertical plate 120, and a mounting table 130, the vertical plate 120 is fixed on the base plate 110, the mounting table 130 is fixedly connected with the vertical plate 120, a plurality of drive mechanisms 310 are arranged at intervals on the vertical plate 120, a plurality of drive rods 320 are arranged at intervals on the mounting table 130, and the pressing plate 200 is located above the drive rods 320.

[0041] Among them, the base plate 110 serves as the basic part of the rack 100, providing overall support and stability. The vertical plate 120 is fixed on the base plate 110, forming a vertical support structure to ensure the stable arrangement of the drive mechanism 310. The mounting table 130 is fixedly connected with the vertical plate 120, further enhancing the stability of the structure and providing a basis for the horizontal arrangement of the drive rod 320. A plurality of drive mechanisms 310 are arranged at intervals on the vertical plate 120, so that each pipe clamping unit can be operated independently to accurately control the clamping or release of the soft pipe of the filling branch. A plurality of drive rods 320 are arranged at intervals on the mounting table 130 to ensure the effective execution of the clamping action. The pressing plate 200 is located above the drive rod 320, further enhancing the stability and effectiveness of the clamping action.

[0042] Specifically, the base plate 110 can be made of high-strength steel to enhance the stability of the overall structure. The vertical plate 120 can be fixed on the base plate 110 by welding or bolt connection to ensure the firmness of vertical support. The mounting table 130 can be fixed with the vertical plate 120 by welding or bolt connection to ensure the stability of horizontal arrangement. The drive mechanism 310 can adopt a motor 311 and a crank linkage mechanism 312, the motor 311 drives the drive rod 320 through the crank linkage mechanism 312 to perform clamping or releasing action. The drive rod 320 can be made of high-strength material to ensure stability and durability during clamping.

[0043] In one of the embodiments, the mounting table 130 is also provided with a support plate 140 adjacent to the drive rod 320 for fixing the adapter connected with the soft pipe of the filling branch.

[0044] The arrangement of the support plate 140 can be achieved in various ways. For example, the support plate 140 can be designed to be adjustable so as to adjust its position and angle according to different filling requirements. In addition, the material of the support plate 140 can be selected to have good wear resistance and corrosion resistance, such as stainless steel or special alloy, to ensure stability and durability in long-term use. The fixing method of the support plate 140 can adopt bolt fixing, welding or quick clamping device to facilitate installation and maintenance.

[0045] Specifically, the main function of the support plate 140 is to fix the adapter, thereby realizing the fixation of the hose and ensuring the stability of the adapter and the hose during the filling process. Through the arrangement of the support plate 140, the loosening or displacement of the adapter during the filling process can be effectively prevented, thereby improving the precision and consistency of the filling.

[0046] Further, in one embodiment, the support plate 140 is two and is arranged on both sides of the drive rod 320.

[0047] This arrangement can effectively disperse the stress of the hose and avoid the hose deviation or loosening caused by unilateral support, thereby improving the stability of the hose fixation. Through the symmetrical arrangement of the two side support plates 140, the hose can be uniformly stressed during the filling process, reducing the filling error caused by uneven stress and improving the filling precision.

[0048] Specifically, the arrangement of the support plate 140 can have various implementation ways. For example, the support plate 140 can be fixed on the mounting table 130 adjacent to the drive rod 320, and used to fix the adapter connected to the hose of the filling branch.

[0049] The support plate 140 can be provided with a plurality of fixing grooves 141, which are used to one-to-one fix the adapters on the hoses of the filling branches, so that each adapter can be accurately fixed at a specific position on the support plate 140, thereby avoiding the problem of unstable fixation of the adapter caused by vibration or movement during the filling process. The shape and size of the fixing groove 141 can be adjusted according to the diameter and material of the adapter to ensure the stability of the adapter in the fixing groove 141. For example, the fixing groove 141 can be designed in U shape or V shape to increase the contact area between the adapter and the fixing groove 141, thereby improving the fixing effect. In addition, the depth and width of the fixing groove 141 can also be optimized according to the characteristics of the adapter to ensure that the adapter will not displace or loosen during the filling process.

[0050] For example, the two ends of the filling branch are connected with the first adapter 512 and the second adapter 513 respectively, the fixing grooves 141 on the two support plates 140 fix the first adapter 512 and the second adapter 513 respectively, and the output end of the second adapter 513 is connected with the filling needle 400, which fills the material into the designated container.

[0051] The design of the fixing grooves 141 not only improves the fixing stability of the adapters on the support plates 140, but also simplifies the installation and disassembly process of the hoses. By placing the adapters one by one in the fixing grooves 141, the operator can quickly and accurately complete the fixing of the hoses, reducing the installation time and error rate. In addition, the design of the fixing grooves 141 also improves the accuracy of the filling process, as each hose is fixed in a predetermined position, ensuring uniform distribution and precise control of the liquid material during the filling process.

[0052] In addition, the shape and size of the support plates 140 can be adjusted according to actual needs to adapt to different specifications of hoses and filling requirements.

[0053] In one embodiment, in order to protect the hoses, the end of the drive rod 320 adjacent to the pressing plate 200 is provided with a first arc surface, and the lower bottom surface of the pressing plate 200 is formed with a second arc surface, and the first arc surface and the second arc surface cooperate to clamp and protect the hoses of the filling branch.

[0054] Specifically, the design of the first arc surface and the second arc surface allows the local pressure on the hose to be reduced through the contact of the arc surfaces when clamping the hose, thereby avoiding damage to the hose due to excessive clamping force. The cooperation of the first arc surface and the second arc surface not only realizes the clamping function of the hose, but also protects the hose through the design of the arc surface, ensuring that the hose will not be damaged during clamping. As a preferred embodiment, the first arc surface and the second arc surface can be designed to have the same or similar radius of curvature to ensure uniform stress on the hose during clamping. In addition, the material of the arc surface can be selected to have high wear resistance and elasticity to further improve the clamping effect and the ability to protect the hose. For example, for softer hoses, a larger radius of curvature can be used to reduce the pressure on the hose; while for harder hoses, a smaller radius of curvature can be used to increase the clamping force.

[0055] Preferably, the pressing plate 200 includes a fixed base plate 210 and a semi-cylindrical plate 220 located at the bottom of the fixed base plate 210, the two ends of the fixed base plate 210 are fixed on the mounting table 130 through the fixed rod 150, and the outer peripheral surface of the semi-cylindrical plate 220 forms the arc surface. The semi-cylindrical plate 220 can be arranged in multiple to correspond to different arrangements of the drive rod 320.

[0056] In one embodiment, as shown in Figure 2 The plurality of driving rods 320 are arranged in two rows, and the two rows of driving rods 320 are arranged in staggered manner along the extension direction of the hoses of the filling branch, so that more hoses can be arranged in a smaller space without interfering with each other.

[0057] As a preferred embodiment, the staggered arrangement of the driving rods 320 can be realized by arranging different staggered mounting holes on the mounting table 130.

[0058] In other embodiments, only one row of driving rods 320 can be arranged.

[0059] In one embodiment, in order to drive the driving rods 320 to move, the driving mechanism 310 includes a motor 311 and a crank linkage mechanism 312, the input end of the crank linkage mechanism 312 is connected with the motor 311, and the output end is connected with the driving rod 320.

[0060] Specifically, the motor 311 serves as a power source to provide the necessary driving force, and the crank linkage mechanism 312 converts the rotary motion of the motor 311 into the linear motion of the driving rod 320. The specific implementation of the crank linkage mechanism 312 can include various variants, for example, the crank linkage mechanism 312 can adopt a single crank or double crank structure, and the length and angle of the connecting rod can be adjusted according to actual needs to realize different motion trajectories and speeds. In addition, the material of the crank linkage mechanism 312 can be selected as high-strength alloy steel to improve its durability and stability. The motor 311 is preferably a servo motor 311.

[0061] In other embodiments, the driving mechanism 310 can also be an electric push rod.

[0062] The present application also provides a filling device, as shown in Figure 3 The filling device includes a material distribution main pipe 510, a filling branch, and the pinch tube device according to any one of the above technical solutions. The material distribution main pipe 510 is provided with a plurality of material distribution ports 511. The filling branch is a plurality of and is connected with the plurality of material distribution ports 511 of the material distribution main pipe 510 one by one. The filling branch includes a material distribution pipe, a hose, an adapter assembly, and a filling needle 400. One end of the material distribution pipe is fixedly connected with the material distribution port 511, and the other end is connected with the adapter assembly. The adapter assembly is used to introduce the material in the material distribution main pipe 510 through the material distribution tank into the hose and further into the filling needle 400.

[0063] In one of the embodiments, the adapter assembly includes a first adapter 512 and a second adapter 513, both ends of the hose are connected to the first adapter 512 and the second adapter 513 respectively, and the upstream of the distribution manifold 510 is connected with a feeding pipe 520 and a buffer tank 530. The material in the feeding pipe 520 is transported into the buffer tank 530, the material in the buffer tank 530 is transported into the distribution manifold 510, the distribution manifold 510 in turn transports the material into the first adapter 512, the hose, the second adapter 513 and the filling needle 400, until the filling needle 400 fills the material into the designated container. In this process, the pinch valve device precisely controls the filling amount by clamping or releasing the hose of the filling branch.

[0064] The filling device of the present application can independently control each driving mechanism 310 by introducing the pinch valve device, thereby adjusting the time when the driving rod 320 approaches or moves away from the pressing plate 200, and realizing the independent control of the hose of each filling branch. This independent control mechanism allows the opening and closing process of each filling needle 400 to be precisely adjusted, thereby solving the problem of inconsistent filling amount caused by the difference between the filling branches, and effectively improving the precision and consistency of filling.
