Description
Technical Field
[0001] This utility model relates to the technical field of weighing module structure, specifically a multifunctional weighing module. Background Technology
[0002] With the rapid development of the industrial age and the gradual upgrading of consumption levels, people's requirements for product quality are constantly increasing. Correspondingly, product manufacturing processes are also constantly being upgraded, and force sensors are playing an important role in the production process of related fields, including the weighing of tanks in biopharmaceutical and food production silos.
[0003] The use of tank weighing often involves the stirring of raw materials, causing the entire container to shake. Therefore, the weighing module needs to have high stability to avoid interference caused by shaking. During the measurement process, to avoid losses due to misoperation, the weighing module needs to have a certain overload protection capability. At the same time, during the installation process at the user end, the weighing module should be simple to install and easy to operate. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a multifunctional weighing module that offers stable measurement, overload protection, and easy operation.
[0005] A multifunctional weighing module, characterized in that it comprises:
[0006] The top plate assembly includes a top plate, two side plates, and a side protrusion at the bottom of each side plate.
[0007] Base plate;
[0008] padding blocks;
[0009] Transmission device;
[0010] A force sensor, which includes a force-measuring end of the sensor;
[0011] Overload protection bolts;
[0012] And anti-overturning bolts;
[0013] The top plate has downward-protruding side plates on both sides of its bottom. Each side plate has an anti-overturning bolt on its outward-facing side protrusion. Each side protrusion has a through hole. The stud of the anti-overturning bolt passes through the through hole and is threaded into the corresponding positioning screw hole of the bottom plate. The diameter of the through hole is larger than the diameter of the stud of the anti-overturning bolt, but smaller than the bolt head size. A pad is installed at the bottom of the non-sensor force-measuring end of the force sensor. A downward-protruding transmission device is fixed in the central area of the top plate, and the transmission device is press-fitted onto the sensor force-measuring end. The upper region of the base plate allows the top plate assembly to float above the base plate. Overload protection bolts are spaced apart directly below the sensor force measuring end. The overload protection bolts are fixed to the corresponding positions on the base plate. There is a gap between the top of the bolt head of the overload protection bolt and the lower end of the sensor force measuring end. The gap ensures that the sensor force measuring end has reliable force measuring deformation after the measurement range is reached. In the overload state, the lower end of the sensor force measuring end is in direct contact with the overload protection bolt, which will transfer part of the force to the overload protection bolt, preventing the sensor force measuring end from undergoing further deformation, thereby protecting the sensor force measuring end from excessive plastic deformation.
[0014] Its further features are:
[0015] It also includes two sets of stabilizer assemblies, each set of stabilizer assemblies including an upper support arm, a stabilizing connecting rod, and a lower support arm; the upper support arm is connected to both sides of the top plate, and the lower support arm is fixedly mounted on one end of the bottom plate; the corresponding stabilizing connecting rod is connected to the upper support arm and the lower support arm respectively, ensuring that the entire module will not deform excessively during the weighing process;
[0016] During the transfer process, it also includes a centering shim assembly and a transport shim. Each side protrusion is equipped with a corresponding centering shim assembly and a transport shim. The centering shim assembly is installed in the through hole to ensure that the anti-overturning bolt will not shake. A transport shim is provided between the bottom of the side protrusion and the upper surface of the bottom plate to ensure that the entire top plate assembly will not shake during the transfer process.
[0017] The lower part of the transmission device is fixedly connected to the upper part of the force measuring end of the sensor to ensure stable and reliable force transmission;
[0018] A central positioning hole is provided at the center of the top plate, and the top of the transmission device is positioned within the central positioning hole.
[0019] The bottom of the positioning screw hole is provided with a stop step to ensure that the anti-overturning bolt is assembled quickly and conveniently.
[0020] With the structure of this utility model, the overload protection bolt is connected to the positioning screw hole of the base plate through the bottom thread. The force sensor is placed above the pad and installed on the base plate by bolts. A downwardly protruding transmission device is fixed in the center area of the top plate. The transmission device is pressed into the upper area of the force measuring end of the sensor. Overload protection bolts are arranged at intervals directly below the force measuring end of the sensor. The overload protection bolts are fixed in the corresponding positions of the base plate. There is a gap between the top of the bolt head of the overload protection bolt and the lower end of the force measuring end of the sensor. The gap ensures that the force measuring end of the sensor has reliable force measuring deformation after the range is reached. Under overload conditions, the sensor... The lower end of the force measuring end is in direct contact with the overload protection bolt, which will transfer part of the force to the overload protection bolt, preventing further deformation of the sensor's force measuring end and thus protecting it from excessive plastic deformation. Furthermore, because the stud of the anti-overturning bolt passes through the through hole and is threaded into the corresponding positioning screw hole of the base plate, and the diameter of the through hole is larger than the stud diameter of the anti-overturning bolt but smaller than the bolt head size, this provides adjustment space at various angles when the top plate shakes, and prevents the top plate from being lifted. In summary, it provides stable measurement, overload protection, and is easy to operate. Attached Figure Description

Detailed Implementation
[0027] A multi-functional weighing module, see Figures 1-4 It includes a top plate assembly 10, a bottom plate 20, two sets of stabilizer assemblies 30, a pad 40, a transmission device 50, a force sensor 60, an overload bolt 70, an overturning bolt 80, a centering pad assembly 90, and a transport pad 100.
[0028] The top plate assembly 10 includes a top plate 11 and two side plates 12, and each side plate 12 is also provided with a side protrusion 13 at the bottom.
[0029] Each stabilizer assembly 30 includes an upper support arm 31, a stabilizing connecting rod 32, and a lower support arm 33;
[0030] The force sensor 60 includes a force measuring end 61;
[0031] The top plate 11 has two downwardly protruding side plates 12 on its bottom sides. Each side plate 12 has an anti-overturning bolt 80 on its outward-facing side protrusion 13. The side protrusion 13 has a through hole 131. The stud 81 of the anti-overturning bolt 80 passes through the through hole 131 and is threaded to the corresponding positioning screw hole 21 of the bottom plate 20. The bottom of the positioning screw hole 21 has a stop step 211 to ensure quick and easy assembly of the anti-overturning bolt 80. The diameter of the through hole 131 is larger than the diameter of the stud 81 of the anti-overturning bolt 80, but smaller than the size of the bolt head 82 of the anti-overturning bolt 80. A pad 40 is installed at the bottom of the non-sensor force measuring end of the force sensor 60. The non-sensor force measuring end of the force sensor 60 is fixed to the corresponding position on the bottom plate 20 by bolts. A downwardly protruding transmission device 50 is fixed in the central area of plate 11. The transmission device 50 is pressed onto the upper area of the sensor force measuring end 61, so that the top plate assembly 10 is suspended above the bottom plate 20. Overload prevention bolts 70 are arranged at intervals directly below the sensor force measuring end 61. The overload prevention bolts 70 are fixed at the corresponding positions of the bottom plate 20. A gap A is left between the top of the bolt head of the overload prevention bolt 70 and the lower end of the sensor force measuring end 61. The gap A ensures that the sensor force measuring end 61 has reliable force measuring deformation within the range. Under overload conditions, the lower end of the sensor force measuring end 61 is in direct contact with the overload prevention bolt 70, which will transfer part of the force to the overload prevention bolt 70, preventing the sensor force measuring end 61 from undergoing further deformation, thereby protecting the sensor force measuring end 61 from excessive plastic deformation.
[0032] In practice, the top plate 11 is connected to the upper support arm 31 on both sides, and the bottom plate 20 is fixedly mounted with the upper support arm 33 on one end. The corresponding stabilizing connecting rod 32 is connected to the upper support arm 31 and the lower support arm 33 respectively.
[0033] During transport, each side protrusion 13 is equipped with a centering shim assembly 90 and a transport shim 100. The centering shim assembly 90 is installed in the through hole 131 to ensure that the anti-overturning bolt 80 does not shake. The transport shim 100 is provided between the bottom of the side protrusion 13 and the upper surface of the base plate 20 to ensure that the entire top plate assembly 10 does not shake during transport. After the multi-functional weighing module is placed in place, the centering shim assembly 90 and the transport shim 100 are removed.
[0034] The lower part of the transmission device 50 is fixed to the upper part of the force measuring end 61 of the sensor to ensure stable and reliable force transmission;
[0035] A central positioning hole 111 is provided at the center of the top plate 11, and the top of the transmission device 50 is positioned within the central positioning hole 111.
[0036] In practice, locking nuts 112 are also provided at the bottom of the four corners of the top plate 11. Each locking nut 112 is equipped with a corresponding locking bolt 110. The locking bolt 110 locks the tank support legs at the user end to the locking nut 112 to ensure reliable weighing operations in the future.
[0037] In practice, the entire weighing module is fixedly installed at the four corners of the base plate 20 through the locking holes 22 and the mounting bolts 120.
[0038] Its working principle is as follows: The overload protection bolt is connected to the positioning screw hole of the base plate through the bottom thread. The force sensor is placed above the pad and installed on the base plate by bolts. A downwardly protruding transmission device is fixed in the center area of the top plate. The transmission device is pressed into the upper area of the force measuring end of the sensor. Overload protection bolts are arranged at intervals directly below the force measuring end of the sensor. The overload protection bolts are fixed in the corresponding positions of the base plate. There is a gap between the top of the bolt head of the overload protection bolt and the lower end of the force measuring end of the sensor. The gap ensures that the force measuring end of the sensor has reliable force measuring deformation within the range. Under overload conditions, the lower end of the force measuring end of the sensor is in direct contact with the overload protection bolt, which will transfer part of the force. The anti-overload bolt prevents further deformation of the sensor's force-measuring end, thus protecting it from excessive plastic deformation. Furthermore, because the stud of the anti-overturning bolt passes through the through hole and is threaded into the corresponding positioning screw hole on the base plate, and the diameter of the through hole is larger than the stud diameter but smaller than the bolt head size, this provides adjustment space at various angles when the top plate shakes, preventing the top plate from being lifted. The weighing module features an easily removable centering shim assembly and a transport shim as positioning devices. The lower locking positioning screw hole of the anti-overturning bolt has a limiting step, facilitating the assembly and installation of the anti-overturning bolt.
[0039] The weighing module is equipped with a stabilizer assembly to improve the product's anti-sway performance; the anti-tipping bolts of the weighing module are half-threaded bolts, and a centering washer is also provided to ensure that the top plate is in a centered position before the product is installed in place.
[0040] The entire weighing module has the following functions:
[0041] 1. Self-returning: It has an automatic return function to prevent the top plate from failing to return to its original position due to interference or other reasons, which would lead to inaccurate measurements.
[0042] 2. Overload protection: It has an overload protection function to prevent the sensor from being damaged due to overload;
[0043] 3. Easy to install and operate on the user end, avoiding inaccurate measurements due to installation problems.
