Description

Technical Field

[0001] The utility model relates to the field of weighing modules, and particularly relates to a circular plate type weighing module. Background Art

[0002] A weighing module is a new type of sensor application structure. It not only ensures the characteristics of high precision and good long-term stability of the shear beam sensor, but also solves the problem of weighing errors caused by improper installation. Weighing modules can be divided into two categories. The static load weighing module is mainly applicable to static load weighing occasions with relatively small lateral forces. The static load weighing module can be very conveniently installed on containers of various shapes. The dynamic load weighing module is mainly applicable to mechanical devices that bear horizontal acting forces, such as assembly lines, conveyor belts, etc. In addition, the dynamic load weighing module can also be used for the transformation of mechanical platform scales. The circular plate type weighing module also belongs to one of the many weighing modules.

[0003] After retrieval, a weighing module with the publication number CN211477355U specifically discloses a weighing module, including an upper top plate, a lower top plate, a weighing sensor, a pressure head, an installation component, and also includes a sensor limit bolt and a support anti-tipping mechanism. One end of the upper top plate is installed on the lower top plate through the installation component, and the other end is installed on the lower top plate through the support anti-tipping mechanism. The pressure head is installed below the upper top plate through the support anti-tipping mechanism. After the weighing sensor is coaxially aligned with the pressure head, it is installed between the pressure head and the lower top plate. The sensor limit bolt is installed around the weighing sensor. The utility model can directly replace the weighing sensor during the weighing process without unloading the products in the material bucket, with simple maintenance and convenient operation. At the same time, it also has an anti-overturning function.

[0004] During the use of the existing circular plate type weighing module, due to the different sizes of the goods placed on the load-bearing plate and the uneven distribution of the weight, during the weighing process, due to the different directions of weight transmission, it is easy to cause uneven stress on the sensors at the bottom, resulting in detection errors. Moreover, there is no means to balance the stress points of the sensors in the above comparative case. In this way, the assembled circular plate type weighing module cannot be used for weight detection work, thus delaying the overall working efficiency.

[0005] Therefore, it is very necessary to invent a circular plate type weighing module to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a circular plate weighing module, which is provided with five different weighing points through an upper bearing plate, a resistance ring, a center of gravity sleeve, a weighing ball, a threaded pin, a limit sleeve, a limit rod and a damping reset rod, thereby avoiding the problem of a circular plate weighing module with a single weighing point, in which the weight transferred to the sensor body is unstable due to the uneven center of gravity of the goods, thus affecting the detection data. In this way, not only the data accuracy of different types of goods is guaranteed under the weighing, but also the weighing method is simple and the overall working time effect is improved, so as to solve the problem that in the use of the circular plate weighing module in the prior art, due to the different sizes of goods placed on the bearing plate, the weight is not evenly distributed. During the weighing process, due to the different weight transfer directions, it is easy to cause uneven force on the bottom sensor, thereby causing detection errors. In the above-mentioned comparative case, no means for balancing the force points of the sensors is provided, so the assembled circular plate weighing module cannot be used in the weight detection work, thereby delaying the overall working time problem.

[0007] In order to achieve the above-mentioned object, the utility model provides the following technical solutions: a circular plate type weighing module, comprising a sensor body, used to bear the weight of goods for measurement;

[0008] An upper load-bearing plate is arranged above the sensor body and is used to place goods, and a resistance ring is fixedly installed at the bottom of the upper load-bearing plate, and a center of gravity sleeve is arranged below the upper load-bearing plate;

[0009] The weighing ball is arranged below the center of gravity sleeve and is used to transfer the weight of the goods. A threaded pin is passed through the top of the sensor body. A limit sleeve is fixedly installed at one end of the threaded pin. A limit rod is arranged inside the limit sleeve, and a damping reset rod is fixedly installed on the top of the limit rod.

[0010] Preferably, a connecting wire is fixedly installed on the outside of the sensor body, a bottom fixing plate is fixedly installed on the bottom of the sensor body, a positioning bolt passes through the top of the bottom fixing plate, and one end of the positioning bolt is movably connected to the module base.

[0011] Preferably, the module base is movably connected to the bottom fixing plate, and the positioning bolts are distributed at equal intervals on the bottom fixing plate.

[0012] Preferably, a main support column is fixedly installed on the top of the module base, a threaded rod is fixedly installed on the top of the main support column, and an external limit nut is movably connected to the outside of the threaded rod.

[0013] Preferably, the number of the main support columns is set to four, and the four main support columns are distributed at equal intervals on the module base.

[0014] Preferably, the limiting sleeve is movably connected to the sensor body, and the damping reset rod and the limiting rod are vertically distributed.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] 1. The utility model is provided with an upper bearing plate, a resistance ring, a center of gravity sleeve, a weighing ball, a threaded pin, a limit sleeve, a limit rod and a damping reset rod. When the device is used to weigh goods, since the weight transmission component is a weighing ball and is spherical, after the goods are placed on the upper bearing plate, according to the center of gravity of goods of different types and sizes, if the weight on the left side is high, the upper bearing plate drives the center of gravity sleeve to fit more closely to the left part of the weighing ball, and vice versa, so that the core gravity of the center of the goods will be evenly distributed to the sensor body through the weighing ball, and at the same time, the upper bearing plate The weight plate is pressed down by the weight of the goods, driving the damping reset rod to contract, so that the limit rod can also weigh the weight transmitted from other parts of the goods at the same time, and evenly distribute it to the sensor body. In this way, the five different weighing points avoid the problem of the round plate weighing module with a single weighing point, because the uneven center of gravity of the goods leads to unstable weight transmitted to the sensor body, thus affecting the detection data. This combination not only ensures the data accuracy of different types of goods, but also simplifies the weighing method and improves the overall work efficiency;

[0017] 2. The utility model is provided with a sensor body, a connecting line, a bottom fixing plate, a positioning bolt, a module base, a main support column, a threaded rod and an external limit nut. When the device is used to weigh goods, the height of the upper load-bearing plate after being pressed down can be adjusted by sleeved multiple groups of external limit nuts on the threaded rod or reducing multiple groups of external limit nuts according to the size and height of the weighing ball currently required for weighing, so that the upper load-bearing plate can drive the goods to fit perfectly on the weighing ball to complete the weight transfer work, and the overall structure of the bottom fixing plate, the positioning bolt and the module base are simple and easy to operate, which is convenient for timely assembly and use of the sensor body in different environments.

[0026] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] The present utility model provides a circular plate weighing module as shown in Figures 1-5 which includes a sensor body 1 for bearing the weight of goods for measurement;

[0028] An upper load-bearing plate 9 is arranged above the sensor body 1 for placing goods, and a contact ring 10 is fixedly installed at the bottom of the upper load-bearing plate 9, and a gravity center sleeve 11 is arranged below the upper load-bearing plate 9;

[0029] A weighing ball 12 is arranged below the gravity center sleeve 11 for transmitting the weight of goods. A threaded pin 13 penetrates through the upper part of the sensor body 1. One end of the threaded pin 13 is fixedly installed with a limiting sleeve 14. A limiting rod 15 is arranged inside the limiting sleeve 14. A damping reset rod 16 is fixedly installed at the top of the limiting rod 15. When the upper load-bearing plate 9 is pressed down by the weight of goods, the damping reset rod 16 is driven to contract, so that the limiting rod 15 also synchronously weighs the weight transmitted from other places of the goods, and can also be evenly distributed to the sensor body 1. In this way, the circular plate weighing module with five different weighing points avoids the problem that the weight transmitted to the sensor body 1 is unstable due to the uneven gravity center of the goods in the circular plate weighing module with a single weighing point, thus affecting the detection data.

[0030] As shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, a connecting line 2 is fixedly installed outside the sensor body 1, a bottom fixing plate 3 is fixedly installed at the bottom of the sensor body 1, a positioning bolt 4 penetrates above the bottom fixing plate 3, one end of the positioning bolt 4 is movably connected to a module base 5. The overall structure of the bottom fixing plate 3, the positioning bolt 4 and the module base 5 is simple and the operation is easy, which is convenient for assembling and using the sensor body 1 in different environments in a timely manner. The module base 5 is movably connected to the bottom fixing plate 3, and the positioning bolts 4 are evenly distributed on the bottom fixing plate 3. The module base 5 has a low manufacturing cost. If a failure occurs, it is also convenient to disassemble and remove the sensor body 1 in a timely manner for inspection and repair. A main support column 6 is fixedly installed above the module base 5, a threaded rod 7 is fixedly installed above the main support column 6, and an outer limit nut 8 is movably connected to the outside of the threaded rod 7. According to the size and height of the weighing ball 12 used when weighing is required currently, the height of the upper bearing plate 9 after being pressed down can be adjusted by sleeving multiple groups of outer limit nuts 8 on the threaded rod 7 or reducing multiple groups of outer limit nuts 8.

[0031] As Figure 1 , Figure 4 and Figure 5 shown, the number of the main support columns 6 is set to four, and the four main support columns 6 are evenly distributed on the module base 5. The main support columns 6 can protect the sensor body 1 to prevent overweight goods from directly pressing down and impacting the sensor body 1, causing unnecessary damage. The limit sleeve 14 is movably connected to the sensor body 1, and the damping return rod 16 and the limit rod 15 are vertically distributed. When the upper bearing plate 9 is pressed down by the weight of the goods, the damping return rod 16 is driven to contract, so that the limit rod 15 also weighs the weight transmitted from other places of the goods synchronously.

[0032] The working principle of this utility model: First, according to the current weighing requirement of the goods, assemble the circular plate weighing module through the bottom fixing plate 3, positioning bolts 4 and module base 5. Then, according to the size and height of the weighing balls 12 used when weighing is needed currently, adjust the height after the upper bearing plate 9 is pressed down by sleeving multiple groups of outer limit nuts 8 on the threaded rod 7 or reducing multiple groups of outer limit nuts 8, so that the upper bearing plate 9 can drive the goods to fit well on the weighing balls 12, completing the weight transfer work. Then, after the installation is completed, the goods to be weighed can be placed on the upper bearing plate 9. As the upper bearing plate 9 drives the contact ring 10 to pass through the threaded rod 7 and contact the outer limit nuts 8, since the weight transfer component is the weighing ball 12 and is spherical, after the goods are placed on the upper bearing plate 9, according to the center of gravity of different types and sizes of goods, if the weight on the left is higher, the upper bearing plate 9 will drive the center of gravity sleeve 11 to fit more closely to the left part of the weighing ball 12, and vice versa. Then, the core gravity of the goods center will be evenly distributed to the sensor body 1 through the weighing balls 12. Then, the upper bearing plate 9 is pressed down by the weight of the goods, driving the damping reset rod 16 to contract, so that the limit rod 15 also weighs the weight transmitted from other parts of the goods synchronously and can also be evenly distributed to the sensor body 1. In this way, the five different weighing points avoid the problem that the weight transmitted to the sensor body 1 is unstable due to the uneven center of gravity of the goods in the circular plate weighing module with a single weighing point, thus affecting the detection data. Subsequently, the weighed weight data will be transmitted to an external machine connected to this device through the connecting wire 2 for the operator to view and record. After the current goods are weighed, the next goods can be replaced for weighing. Finally, after completing all the installation and use work of the circular plate weighing module according to the above operations, the device can be maintained daily. Just like this, the use process of the circular plate weighing module is completed.

[0033] Only some exemplary embodiments of the present utility model have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
