Description

Technical Field

[0001] The utility model relates to the technical field of weighing devices, in particular to a load-bearing weighing device in an electronic weighing system. Background Art

[0002] The existing publicly available load-bearing weighing device or weighing module is basically composed of a weighing sensor, and an upper fixing plate, a lower fixing plate, a supporting assembly and a fastening assembly for fixing the sensor. By connecting the upper fixing plate to the weighed equipment, such as a weighing tank, and connecting the lower fixing plate to the equipment foundation, the purpose of overall simplification of the on-site use and installation of the sensor is achieved.

[0003] The existing weighing module installation requirements are relatively complex. There are different installation forms in one set of devices, and there are corresponding requirements for the installation direction, installation position, and installation sequence of the device, which makes it difficult for customers to understand.

[0004] In addition, some designed devices lack corresponding functions. Some devices are affected by the internal stirring force of the weighing equipment, as well as external forces such as environmental wind and vibration, which makes the sensor affected by horizontal and vertical forces, resulting in relative position movement, which brings corresponding safety hazards and makes it difficult to ensure weighing accuracy. At the same time, some devices currently use scallops as the reset structure of the module, but since the single-point force of scallops is difficult to recover when the inclination angle is large, it leads to inaccurate weighing data.

[0021] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0022] Please refer to Figure 1-4 A load-bearing weighing device in an electronic weighing system includes a weighing sensor 1, the left end of the weighing sensor 1 is fixedly mounted on a lower mounting plate 4, the right end of the lower mounting plate 4 is fixedly connected to an upper mounting plate 6, a pressure head 3 is mounted on the top of the upper mounting plate 6, the pressure heads 3 are arranged in two groups, a steel ball 2 is arranged between the two groups of pressure heads 3, an upper pressure plate 5 is fixedly mounted on the top of the pressure head 3, and the upper pressure plate 5 is connected to the mounting plate 6 through a stud 9; the load-bearing weighing device is an independent weighing assembly unit, and the bolts pass through the matching holes of the upper mounting plate 6 and the lower mounting plate 4 when leaving the factory, so that the single-point weighing sensor 1 is not affected by external forces during the entire assembly, transportation and on-site installation process, and the weighing sensor is well protected in each process to avoid damage to the sensor caused by lateral impact force. The load-bearing weighing device can be installed as a whole in the weighing system without any other installation accessories.

[0023] The left end of the lower mounting plate 4 is fixedly connected to the weighing sensor 1 by a high-strength bolt 8, and the right end of the upper mounting plate 6 is fixedly connected to the weighing sensor 1 by a high-strength bolt 7; the box-type side-mounted sensor ensures that the load-bearing weighing device is not affected by horizontal external forces and produces relative displacement.

[0024] The two groups of pressure heads 3 are provided with grooves at opposite ends thereof, and steel balls 2 are placed in the grooves.

[0025] A groove is provided in the middle of the top of the upper mounting plate 6, and the pressure head 3 below is fixedly mounted thereon.

[0026] A groove is provided in the middle of the bottom of the upper pressing plate 5, and the pressing head 3 above is fixedly installed.

[0027] The stud bolts 9 are arranged at both ends of the upper mounting plate 6 , the bottom of the stud bolts 9 is fixedly connected to the upper mounting plate 6 , and the top of the stud bolts 9 is fixedly connected to the upper pressing plate 5 .

[0028] After being installed in the weighing system, loosen the nuts of the accessory fixing stud 9 and the upper mounting plate 6, keep a certain gap, and then tighten the nuts, then the single point sensor starts to bear the load and is in a normal weighing state. The entire installation and use process is simple and convenient. After the single point sensor is loaded, the upper pressure plate 5 is in a floating state and only bears vertical force, so that the weighing system has a small weighing error and high precision.

[0029] The mounting accessories of the load-bearing weighing device are fixedly mounted on the lower base plate. When the device needs maintenance or replacement of the sensor, the sensor can be disassembled and replaced by lifting the device until the upper pressure plate and the steel ball are separated, and the device can still maintain the original installation state until the sensor is replaced;

[0030] The working principle of the utility model is: when the weighing system is subjected to horizontal impact force or overturning force, the cooperation between the stud 9, the upper pressure plate 5 and the upper mounting plate 6 can ensure that the single-point sensor 1 is not damaged by the additional horizontal force or overturning force. When the external force is eliminated, the single-point sensor 1 is restored to its initial vertical state through the restoring force generated by the upper and lower pressure heads of the single-point sensor and the spherical surface of the steel ball, thereby ensuring the long-term stability and high-precision requirements of the sensor and the safety of the entire weighing system.

[0031] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
