[0002] Weighing is a concept widely used in life, which refers to the act of measuring weight with a balance or other measuring tools. In our daily life, weighing plays an important role. Weighing is crucial in the field of cooking. Weighing tools in the kitchen, such as kitchen scales, can help us ensure the accurate measurement of ingredients. Whether in the baking process of bread, cakes, etc., or in the case of precise seasoning ingredients in cooking, weighing plays an important role in food production. By accurately weighing, we can ensure that the taste, texture, and quality of the food meet expectations.

The raw materials can be weighed and measured by the electronic scale for the second weighing and measurement, enabling accurate weighing and measurement of the raw materials. When the sleeve is displaced, the friction between the guiding gear and the guiding rack can reduce the transmitted kinetic energy. When an object slides on a horizontal plane and is affected by sliding friction, the sliding friction will do negative work on the object, resulting in a decrease in the object's speed and thus a reduction in kinetic energy. The sealing block can buffer the impact generated during contact to prevent the sleeve from descending too quickly and causing a large impact on the connecting rod, damaging it and affecting its use. 2. In the present invention, through the design of the closing assembly, the raw materials inside the weighing hopper can be limited, and together with the weighing sensor, the raw materials can be preliminarily weighed and measured without manual operation, preventing errors that are likely to occur during measurement after a large amount of manual loading. At the same time, the labor intensity is high, and the problem that weighing and measurement cannot be industrialized, large-scale, and in a production line during the food processing process is solved.

DETAILED DESCRIPTION OF THE INVENTION

[0017] To make the technical problems solved by the present invention, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0018] Embodiment: As Figures 1 to 8 shown, a weighing and metering device for food includes: a base body 1, a first conveyor frame 2 is provided at the top of the base body 1, and an electronic scale 3 is provided at one end of the base body 1 close to the first conveyor frame 2. A sensing block 4 is provided at one end of the electronic scale 3 close to the first conveyor frame 2. The first conveyor frame 2 is connected to the base body 1 through a plurality of buffer components 5. Second conveyor frames 6 are provided at both ends of the base body 1, and a connecting frame 7 is provided outside the base body 1. A vibration bin 8 is provided at the top of the connecting frame 7. A weighing hopper 9 is provided at the bottom of the vibration bin 8. Weighing sensors 10 are provided at both ends of the weighing hopper 9, and a closing component 11 is provided at the bottom of the weighing hopper 9. A blanking hopper 12 is provided at the bottom of the connecting frame 7 and below the closing component 11; The buffer component 5 is used to buffer the impact received by the first conveyor frame 2, and the buffer component 5 is composed of a sleeve 13, a connecting rod 14, an air inlet 15 and an air outlet 16. The sleeve 13 is located at one end of the first conveyor frame 2 close to the base body 1. The connecting rod 14 is located at one end of the base body 1 close to the sleeve 13. The air inlet 15 is opened at one end of the connecting rod 14 close to the sleeve 13. The air outlet 16 is opened outside the air inlet 15 and is located inside the connecting rod 14; The closing component 11 is used to limit and block the raw materials inside the weighing hopper 9.

[0019] In this embodiment, the connecting rod 14 extends into the sleeve 13 and is provided with a sealing block 17. The external structure size of the sealing block 17 corresponds to the internal structure size of the sleeve 13. The connecting rod 14 is connected to the sleeve 13 through the sealing block 17. Connecting the sealing block 17 and the sleeve 13 enables the connecting rod 14 to be connected to the sleeve 13. When gas is introduced into the sleeve 13, the sealing block 17 can prevent gas leakage, which may affect the support of the connecting rod 14 and the sleeve 13 for the first conveyor frame 2. When the top of the connecting rod 14 contacts the top end inside the sleeve 13, the sealing block 17 can buffer the impact generated by the contact therebetween and prevent damage to the connecting rod 14 and the sleeve 13, affecting the use.

[0020] In this embodiment, blocking blocks 18 are rotatably connected to the outer sides of the air inlet 15 and the air outlet 16. The diameter of the blocking block 18 is larger than the diameters of the air inlet 15 and the air outlet 16, and the two groups of blocking blocks 18 are respectively connected to the air inlet 15 and the air outlet 16 through torsion springs. When connecting the two groups of blocking blocks 18 to the air inlet 15 and the air outlet 16 respectively, when gas is introduced into or discharged from the inside of the sleeve 13, the blocking block 18 cooperates with the torsion spring to block the air inlet 15 or the air outlet 16, preventing gas leakage and affecting the use.

[0021] In this embodiment, two connecting grooves 19 are provided inside the sleeve 13. A guiding rack 20 is provided inside the connecting groove 19. Guide gears 21 are rotatably connected to both ends of the connecting rod 14 and at the bottom of the sealing block 17. The guide gears 21 are meshed with the guiding rack 20. By meshing the guide gears 21 with the guiding rack 20, the connecting rod 14 is connected to the sleeve 13. When the sleeve 13 is displaced, it drives the guiding rack 20 to displace and contact the guide gears 21. The guide gears 21 guide the guiding rack 20, enabling the sleeve 13 to be guided and preventing the sleeve 13 from shifting. At the same time, when the sleeve 13 is displaced, the frictional force between the guide gears 21 and the guiding rack 20 can reduce the transmitted kinetic energy. When an object slides on a horizontal plane and is subjected to sliding friction, the sliding friction will do negative work on the object, causing the speed of the object to decrease, and thus reducing the kinetic energy, preventing the sleeve 13 from descending too fast and causing a large impact on the connecting rod 14, damaging it and affecting the use.

[0022] In this embodiment, a trachea is provided at one end of the connecting rod 14 away from the sleeve 13. Multiple tracheas are connected through an air pump, and the air pump is installed inside the base body 1. The air pump is started to introduce gas into the trachea, so that the gas can be introduced into the air inlet 15 through the trachea and then into the inside of the sleeve 13. By increasing the air pressure inside the sleeve 13, the sleeve 13 is displaced, driving the first conveyor 2 to displace, so that the contact between the first conveyor 2 and the sensing block 4 is disconnected, and thus weighing can be performed again. When weighing the raw materials, the gas inside the sleeve 13 is pumped out, causing the sleeve 13 to slowly descend, so that the first conveyor 2 can contact the sensing block 4, and the raw materials can be weighed and measured by the electronic scale 3.

[0023] In this embodiment, the closing assembly 11 is composed of a connecting frame 22, closing blocks 23, rotating rods 24, and rotating blocks 25. The connecting frame 22 is located at the bottom of the weighing hopper 9. Both groups of closing blocks 23 are rotatably connected to one end of the connecting frame 22 away from the weighing hopper 9. Both groups of rotating rods 24 are rotatably connected to the outside of the closing blocks 23. The rotating block 25 is located between the two groups of rotating rods 24. Through the closing assembly 11, the raw materials inside the weighing hopper 9 can be limited, and in cooperation with the weighing sensor 10, the raw materials can be initially weighed and measured.

[0024] In this embodiment, the external structure size of the closing block 23 is designed to correspond to the internal structure size of the weighing hopper 9, and the closing block 23 is connected to the weighing hopper 9 through the connecting frame 22. Connecting the closing block 23 and the connecting frame 22 enables the closing block 23 to block the weighing hopper 9.

[0025] In this embodiment, the rotating block 25 is rotatably connected to the rotating rod 24. On both ends of the weighing hopper 9 and on the side close to the rotating block 25, a first telescopic cylinder is provided. The driving end of the first telescopic cylinder is connected to the rotating block 25. Starting the first telescopic cylinder drives the rotating block 25 to displace, causing the rotating rod 24 to rotate, driving the closing block 23 to rotate, opening the two groups of closing blocks 23, enabling the raw materials inside the weighing hopper 9 to be introduced into the inside of the feeding hopper 12, and then into the container for placing the raw materials. Resetting the rotating block 25 causes the rotating rod 24 to reset, driving the two groups of closing blocks 23 to close, enabling the weighing hopper 9 to be closed.

[0026] In this embodiment, a plurality of transmission blocks 26 are provided at one end of the vibration bin 8 close to the weighing hopper 9. The ends of the plurality of transmission blocks 26 away from the vibration bin 8 are connected through a vibrator 27. Starting the vibrator 27 to vibrate the transmission blocks 26 enables the vibration bin 8 to vibrate and introduce the raw materials inside it into the inside of the weighing hopper 9.

[0027] In this embodiment, a limiting plate 28 is rotatably connected to the bottom of the vibration bin 8 and outside the vibrator 27. A rotating frame 29 is fixedly connected to the outside of the limiting plate 28. A second telescopic cylinder is provided on the outside of the vibration bin 8 and at one end close to the rotating frame 29. The driving end of the second telescopic cylinder is connected to the rotating frame 29. Starting the second telescopic cylinder drives the rotating frame 29 to rotate, enabling the limiting plate 28 to rotate and opening the vibration bin 8.

[0028] Embodiment: During actual use, place the container on the top of the second conveyor rack 6, and displace it to the first conveyor rack 2 through the second conveyor rack 6 so that the container can be displaced below the hopper 12. Start the second telescopic cylinder to drive the rotating frame 29 to rotate, so that the limiting plate 28 can rotate and open the vibrating bin 8. Start the vibrator 27 to vibrate the transmission block 26, so that the vibrating bin 8 can vibrate and introduce the raw materials inside into the weighing hopper 9. Start the first telescopic cylinder to drive the rotating block 25 to displace, so that the rotating rod 24 rotates, driving the closing block 23 to rotate and opening the two groups of closing blocks 23, so that the raw materials inside the weighing hopper 9 can be introduced into the hopper 12 and then into the container for placing the raw materials. The raw materials can be preliminarily weighed and measured by the weighing sensor 10. Reset the rotating block 25, so that the rotating rod 24 is reset, driving the two groups of closing blocks 23 to close, so that the weighing hopper 9 can be closed. When the raw materials are introduced into the container, due to their own weight, they are introduced onto the first conveyor rack 2 and descend, sucking out the gas inside the sleeve 13, causing the sleeve 13 to slowly descend, so that the first conveyor rack 2 can contact the sensing block 4. The raw materials can be weighed and measured by the electronic scale 3 for the second weighing and measurement, so as to accurately weigh and measure the raw materials. When the sleeve 13 is displaced, the frictional force between the guiding gear 21 and the guiding rack 20 can reduce the transmitted kinetic energy. When an object slides on a horizontal plane and is subjected to sliding friction, the sliding friction will do negative work on the object, causing the speed of the object to decrease and thus reducing the kinetic energy. Cooperating with the sealing block 17 can buffer the impact generated by the contact between them, preventing the sleeve 13 from descending too fast and causing a large impact on the connecting rod 14, damaging it and affecting the use. Through the overall design, not only is the working intensity greatly reduced, but also the production efficiency is improved, realizing the automatic weighing and measurement of food processing. Most importantly, it solves the problem that the weighing in the process of food processing cannot be industrialized, large-scale, and on a production line. Compared with the existing weighing and measuring devices, the present invention can improve the overall practicality of the weighing and measuring device through the design.

Therefore, the appended claims are intended to be construed to include the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0030] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
