Description

Technical Field

[0001] This utility model belongs to the field of nanoscale scale technology, and in particular relates to a nanoscale scale device. Background Technology

[0002] In the feed processing industry, the precision of animal feed formulation is crucial for the healthy growth of animals. To ensure the nutritional balance of the animals being fed, trace elements such as calcium, iron, zinc, and selenium need to be added to the feed, and the precision requirements for these ingredients are becoming increasingly stringent.

[0003] Currently, the feed processing industry commonly uses either large-range single-sensor weighing schemes or small-range multi-sensor weighing schemes for small-batch batching. Large-range single-sensor weighing schemes use a single weighing sensor to bear the weight of components such as the weighing hopper, vibrator, and discharge valve, as well as the weight of the small batches to be batched. However, due to the large weight of the weighing hopper, vibrator, and discharge valve, the weighing sensor's range increases accordingly, which can easily affect weighing accuracy. Common weighbridges have an accuracy error of ±50kg, which clearly cannot meet the high-precision requirements for small-batch batching. On the other hand, small-range multi-sensor weighing schemes require high precision in the installation and positioning of multiple weighing points, increasing manufacturing and installation difficulty. Furthermore, the electrical signals of multiple weighing sensors are prone to signal deviation when articulated and coupled, further affecting weighing accuracy. In addition, the cost of multi-sensor schemes is relatively high, hindering their widespread adoption in the feed processing industry. Therefore, we propose this nanoscale weighing device to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the prior art by providing a nanoscale balance device.

[0005] To achieve the above objectives, the utility model employs the following technical solution: a nanoscale weighing device, comprising a mounting frame, a support frame fixedly mounted on the mounting frame, a rotating shaft rotatably mounted inside the support frame, both ends of the rotating shaft extending to the outside of the support frame, a drive assembly for driving the rotating shaft to rotate on one side of the support frame, a mounting assembly on the end of the rotating shaft away from the drive assembly, a weighing sensor mounted inside the mounting assembly, a weighing hopper mounted on the measuring end of the weighing sensor, a support plate mounted on the rotating shaft, a vibrator mounted on one side of the support plate, and the output end of the vibrator contacting the side wall of the weighing hopper.

[0006] By adopting the above technical solution, the weight of the unloading valve and the vibrator is excluded from the measurement range of the weighing sensor, so that the weighing sensor only bears the weight of the weighing hopper and the weight of the small material to be mixed, thereby greatly reducing the tare weight. This design enables the weighing sensor to measure the actual weight of the small material to be mixed more accurately within the appropriate range, significantly improving the batching and weighing accuracy.

[0007] Furthermore, the driving component is a swing cylinder, and the output end of the driving component is fixed to the tilting shaft.

[0008] By adopting the above technical solution, the rotating shaft is driven to rotate, thereby completing the unloading work of the weighing hopper.

[0009] Furthermore, the mounting assembly includes a fixed bracket fixedly mounted on the end of the tilting shaft away from the drive assembly, and two limiting blocks are fixedly mounted on the inner wall of the fixed bracket, with the load cell mounted between the two limiting blocks by bolts.

[0010] The above technical solution is used to fix the weighing sensor onto the flipping shaft.

[0011] Furthermore, the measuring end of the weighing sensor has a screw hole, and a connecting cover is fixedly installed at the bottom of the weighing hopper. The connecting cover is fixed to the measuring end of the weighing sensor by bolts.

[0012] The above technical solution is used to fix the weighing bucket onto the weighing sensor.

[0013] Furthermore, the mounting frame includes a main frame, side frames, and connecting rods. There are at least two sets of side frames, all of which are spaced apart on the same side of the main frame. The connecting rods are installed between the side frames. The bottom edges of the main frame and the side frames are flush. The top beam of the side frame is inclined and connected to the main frame.

[0014] By adopting the above technical solution, the top beam of the frame body is set at an inclination, which can better adapt to the tilting and unloading operation of the weighing hopper.

[0015] Furthermore, the support frame includes a base plate and two side plates, with multiple reinforcing plates fixedly installed between the two side plates and the base plate, and the base plate is fixed to the top of the main frame by bolts.

[0016] By adopting the above technical solution, the strength of the support frame is improved, thereby enhancing the stability of the entire device.

[0017] Furthermore, a buffer assembly is provided between the flipping shaft and the support frame.

[0018] Furthermore, the buffer assembly includes a collar fixedly mounted on the flip shaft, a buffer plate fixedly mounted on the outer wall of the collar, and two limit buffers fixedly mounted on the support frame. The buffer plate, collar, and limit buffers are on the same plane.

[0019] The above technical solution is used to provide a buffering effect when the weighing hopper is tilted and unloaded.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This invention eliminates the weight of the unloading valve and vibrator from the measurement range of the weighing sensor, allowing the weighing sensor to bear only the weight of the weighing hopper and the weight of the small materials to be weighed. At the same time, by optimizing the shape and processing technology of the weighing hopper, the weight of the weighing hopper can be compressed to the limit, thereby greatly reducing the tare weight. This design enables the weighing sensor to measure the actual weight of the small materials to be weighed more accurately within the appropriate range, significantly improving the weighing accuracy of the batching. This provides a feasible design direction for developing small-range, high-precision batching scales. Attached Figure Description

[0031] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] In the description of this utility model, it should be noted that the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] like Figure 1 and Figure 4 As shown, the specific solution of the embodiment is as follows: A nanoscale weighing device includes a mounting frame 1, a support frame 9 fixedly mounted on the mounting frame 1, a flip shaft 3 rotatably mounted inside the support frame 9, both ends of the flip shaft 3 extending to the outside of the support frame 9, a drive assembly 5 for driving the flip shaft 3 to rotate is provided on one side of the support frame 9, a mounting assembly is provided at the end of the flip shaft 3 away from the drive assembly 5, a weighing sensor 6 is mounted on the inner side of the mounting assembly, a weighing hopper 8 is mounted on the measuring end of the weighing sensor 6, a support plate 14 is also fixedly mounted on the flip shaft 3, a vibrator 4 is fixedly mounted on one side of the support plate 14, and the output end of the vibrator 4 contacts the side wall of the weighing hopper 8.

[0034] Among them, the drive component 5 is a swing cylinder, which is fixed to the side wall of the support frame 9, and the output end of the drive component 5 is fixed to the tilting shaft 3, such as Figure 6 , Figure 7 and Figure 8 As shown, the small material to be weighed is placed inside the weighing hopper 8, and the weighing hopper 8 is flipped by the swing cylinder to complete the unloading work.

[0035] In addition, since the vibrator 4 is mounted on the flip shaft 3, the weighing sensor 6 only bears the weight of the weighing hopper 8 and the weight of the small material to be weighed. At the same time, by optimizing the shape and processing technology of the weighing hopper 8, the weight of the weighing hopper 8 can be compressed to the limit, thereby greatly reducing the tare weight. This design enables the weighing sensor 6 to measure the actual weight of the small material to be weighed more accurately within the appropriate range, significantly improving the weighing accuracy of the material. This provides a feasible design direction for developing a small-range, high-precision material weighing scale.

[0036] It is worth noting that bearings are fixedly installed on both side walls of the support frame 9, and the tilting shaft 3 is installed on the inner wall of the bearing, thereby achieving a rotatable connection with the support frame 9.

[0037] Please see Figure 2 and Figure 3 In this embodiment, the mounting assembly includes a fixed frame 12 fixedly mounted on the end of the flip shaft 3 away from the drive assembly 5. Two limit blocks 10 are fixedly mounted on the inner wall of the fixed frame 12. The weighing sensor 6 is mounted between the two limit blocks 10 by bolts. The measuring end of the weighing sensor 6 has a screw hole. A connecting cover 11 is fixedly mounted on the bottom of the weighing hopper 8. The connecting cover 11 is fixed to the measuring end of the weighing sensor 6 by bolts.

[0038] The weighing hopper 8 and the connecting cover 11 are integrated. The connecting cover 11 is designed to facilitate the connection between the weighing hopper 8 and the weighing sensor 6, and also to facilitate the subsequent disassembly of the weighing hopper 8.

[0039] Please see Figure 1 In this embodiment, the mounting frame 1 includes a main frame 101, side frames 102, and connecting rods 103. There are at least two sets of side frames 102, and all side frames 102 are spaced apart on the same side of the main frame 101. The connecting rods 103 are installed between the side frames 102. The bottom edges of the main frame 101 and the side frames 102 are flush. The top beam of the side frames 102 is inclined and connected to the main frame 101. The support frame 9 includes a base plate 901 and two side plates 902. Multiple reinforcing plates are fixedly installed between the two side plates 902 and the base plate 901. The base plate 901 is fixed to the top of the main frame 101 by bolts.

[0040] The top beam of the frame body 102 is inclined to accommodate the tilting of the weighing hopper 8 during the unloading process, and the inner side of the frame body 102 is also convenient for placing the container for subsequent material receiving.

[0041] In addition, the strength of the support frame 9 can be increased by the reinforcing plate, thereby improving the stability of the entire device.

[0042] Please see Figure 5 In this embodiment, a buffer assembly is also provided between the flip shaft 3 and the support frame 9. The buffer assembly includes a collar 13 fixedly installed on the flip shaft 3. A buffer plate 2 is fixedly installed on the outer wall of the collar 13. Two limit buffers 7 are also fixedly installed on the support frame 9. The buffer plate 2, the collar 13 and the limit buffers 7 are on the same plane.

[0043] When the weighing hopper 8 is in a vertical position, the buffer plate 2 is in contact with the limit buffer 7 on the same side. When the weighing hopper 8 flips during the unloading process, the buffer plate 2 will flip synchronously. When the opening of the weighing hopper 8 is facing down, the buffer plate 2 will contact the limit buffer 7 on the other side, thereby playing a buffering role and reducing the impact and vibration of the weighing hopper 8 and its connected parts due to sudden stop. This can ensure the smoothness of the unloading process. At the same time, the limit buffer 7 can also play a limiting role, making it less likely for the weighing hopper 8 to flip too much and affect the subsequent loading work.

[0044] In addition, the limit buffer 7 is existing technology and is used to provide a buffering effect.

[0045] The above embodiment works as follows: During the feeding process, the opening of the weighing hopper 8 faces upward, and the small material enters the interior of the weighing hopper 8. The weighing sensor 6 detects the weight change of the weighing hopper 8 in real time and displays it on the weighing instrument. When the feeding is completed, the swing cylinder is activated, and the swing cylinder drives the flipping shaft 3 to rotate, thereby driving the weighing hopper 8 and the weighing sensor 6 to flip as a whole. The small material gradually pours down from the weighing hopper 8. The vibrator 4 is activated to strike the shell of the weighing hopper 8 to prevent the small material from sticking to the inner wall of the weighing hopper 8 until the unloading is completed. Then, the swing cylinder is activated again to flip the weighing hopper 8 so that its opening faces upward, and the weighing hopper 8 is reset.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
