[0002] A weighing device is an electronic weighing device that integrates modern sensor technology, electronic technology, and computer technology. By weighing the weight of an object and converting the object weight into the number of objects, it is often used in inventory counting and inventory taking operations.

[0003] When the existing weighing device is in use, the object to be weighed is placed in the hopper of the weighing device. However, the sizes and types of the objects to be weighed are different. When the size of the object to be weighed is larger than the size of the hopper, the current solution is to use a larger weighing sensor, make a larger weighing module, or replace the hopper with a larger size to adapt to the object to be weighed.

[0004] However, there are certain defects in the existing technology. It is necessary to prepare weighing modules and hoppers of various sizes to adapt to objects to be weighed of different sizes, which wastes materials, increases costs, and is complex to operate. Also, the problem of storing the replaced weighing modules and hoppers needs to be solved. Therefore, a modular weighing device is proposed. Content of the Utility Model

The two side plates are respectively located on both sides of the weighing base, and the bottoms of the two side plates are both clamped with the upper end of the hopper. A front plate is clamped on the side away from the back plate between the two side plates. A weighing sensor is fixedly connected inside the weighing base, and the hopper cooperates with the weighing sensor.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0024] A modular weighing device, as Figures 1-5 shown, includes a weighing seat 1. A hopper 4 for containing the object to be weighed is fixedly connected to the upper end of the weighing seat 1. A back plate 7 is clamped at the position of the tail of the weighing seat 1 at the upper end of the hopper 4. Two groups of side plates 8 are clamped on one side of the back plate 7. The two groups of side plates 8 are respectively located on both sides of the weighing seat 1, and the bottoms of the two groups of side plates 8 are both clamped to the upper end of the hopper 4. A front plate 9 is clamped on the side away from the back plate 7 between the two groups of side plates 8. A weighing sensor 6 is fixedly connected inside the weighing seat 1, and the hopper 4 cooperates with the weighing sensor 6.

[0025] When the size of the object to be weighed is larger than the size of the hopper 4 configured for a single weighing module, the side plates 8 and the front plate 9 of the adjacent hoppers 4 can be removed, and two or more hoppers 4 can be expanded and combined into a large-size hopper 4 to adapt to the size of the object to be weighed. By calculating the size of the object to be weighed through the combined weighing and counting function, it not only saves materials and simplifies the operation process, but also solves the problems of the configuration and storage of redundant weighing modules and hoppers 4.

[0026] Principle of combined weighing and counting: First, combine the hoppers to expand the hopper size: The size of the object A to be weighed is larger than the size of hopper A or hopper B. At this time, we remove the side plates and the front plate at the adjacent position of hopper A and hopper B, and combine hopper A and hopper B into a large hopper. The object A to be weighed is placed in hopper A and hopper B at the same time.

[0027] Then, perform combined weighing and output the quantity: The weighing sensor A transmits the weight data of the object A to the control board A through the serial port, and the weighing sensor B transmits the weight data of the object A to the control board B through the serial port. The control board A is the main arithmetic unit, and the control board B is the slave arithmetic unit. The control board B transmits the obtained weight information to the control board A. The control board A combines the weight data of the sensor A and the sensor B, calculates the quantity of the object to be weighed through a specific algorithm (prior art), outputs the quantity information to the display screen A, and at the same time outputs the quantity information to the control board B. The control board B outputs the received quantity information to the display screen B, so that the display screens A and B simultaneously display the quantity of the object to be weighed after the hoppers are combined.

[0028] As Figure 2As shown in the figure, a control board 2 is fixedly connected to the front end of the weighing seat 1. A display screen 3 and a key 5 are fixedly connected to one side of the control board 2. The display screen 3 is located at the middle position of the control board 2, and the key 5 is located on one side of the display screen 3.

[0029] The button operates the weighing device through the control board 2, and the display screen 3 displays the data of the weighing device.

[0030] As Figure 1 shown, a protective cover 10 is snap-connected to the front end of the weighing seat 1. The protective cover 10 covers the control board 2. The display screen 3 and the key 5 are both located inside the protective cover 10, and the protective cover 10 is in press fit with the key 5.

[0031] The protective cover 10 protects the control board 2, the display screen 3 and the key 5 from being easily damaged or getting water. The position of the protective cover 10 corresponding to the display screen 3 is transparent, and a pressing area is provided on the surface of the protective cover 10 to press the key 5.

[0032] As Figure 1 , Figure 3 , Figure 4 shown, a plurality of mounting grooves 13 are opened at the upper end of the hopper 4. Mounting blocks are fixedly connected to the lower ends of the back plate 7, the side plates 8 and the front plate 9. The plurality of mounting blocks are respectively snap-connected and installed with the plurality of mounting grooves 13.

[0033] The lower ends of the back plate 7, the side plates 8 and the front plate 9 are all installed with the hopper 4 through the mounting blocks and the mounting grooves 13, which is convenient for disassembly and assembly, and the installation structure is stable.

[0034] As Figure 1 , Figure 3 , Figure 4 shown, two card slots 12 are opened on both sides of the upper end of the back plate 7. Two clamping plates 14 are fixedly connected to one end of the two side plates 8 close to the back plate 7. The two clamping plates 14 are respectively snap-connected and installed with the two card slots 12.

[0035] The two side plates 8 install the back plate 7 from top to bottom, and the side plates 8 can be disassembled by pulling upwards.

[0036] As Figure 1 , Figure 3 , Figure 4 shown, two card slots 15 are opened above one end of the two side plates 8 away from the back plate 7. Two clamping plates 11 are fixedly connected to both sides of the front plate 9. The two clamping plates 11 are respectively snap-connected and installed with the two card slots 15.

[0037] The front plate 9 clamps the two side plates 8 from top to bottom, and the front plate 9 can be disassembled by pulling upwards.

[0038] The working principle of a modular weighing device provided by the present utility model is as follows:

[0039] When the size of the object to be weighed is larger than the size of the hopper 4 configured for a single weighing module, the side plates 8 of adjacent hoppers 4 can be removed, and two or more hoppers 4 can be expanded and combined into a large-sized hopper 4 to adapt to the size of the object to be weighed. By calculating the size of the object to be weighed through the combined weighing and counting function, it not only saves materials and simplifies the operation process, but also solves the problems of the configuration and storage of redundant weighing modules and hoppers 4.
