Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a metering machine with a quantitative weighing structure. Background Technology

[0002] A common type of metering machine with a quantitative weighing structure achieves quantitative weighing of materials by precisely controlling the input amount. Its main components include a hopper, sensors, a control system, a feeding device, and an output device. Material enters the hopper through the feeding device. The sensors monitor the weight change of the material in the hopper in real time. The control system automatically adjusts the feeding speed according to the set target weight to ensure accurate weighing. When the weight of the material in the hopper reaches the predetermined value, the control system automatically stops feeding and discharges the material through the output device, completing one quantitative weighing operation.

[0003] Patent CN215043879U discloses a tea quantitative weighing device. Specifically, the patent discloses a technical solution that includes a storage tank and a weighing box. The tea is poured into the tank by opening the lid. The tea is screened through a mesh inside a baffle plate. Fine tea particles pass through the mesh into the upper part of an inclined plate, then through a discharge hole into a rotating discharge cylinder for collection. The screened tea is then poured into the upper part of the weighing plate through a discharge port. A pressure sensor sets a value, and when a quantitative threshold is reached, the electromagnetic valve closes, activating an electric push rod to pull a support tube to rotate under the action of a rotating platform. This causes the weighing plate to rotate and discharge the tea from the discharge port. This solution achieves the technical effect of "solving the problem of needing to weigh tea after processing for packaging purposes."

[0004] Existing devices rely solely on baffles and screens for screening, which is a relatively simple method. Especially when processing fine or unevenly sized materials, this may lead to incomplete screening. Due to the wide range of raw material particle sizes, the aperture of the baffles and screens often cannot meet the requirements for precise screening of different particle sizes. Fine particles can easily pass through the screen, causing the loss of unqualified materials and affecting the final screening effect.

[0005] Therefore, we propose a metering machine with a quantitative weighing structure. Utility Model Content

[0029] Example

[0030] like Figure 1-6 As shown, this utility model provides a technical solution: a metering machine with a quantitative weighing structure, including a metering machine body 1, a motor 3 fixedly installed on one side of the metering machine body 1, a rotating component provided at the output end of the motor 3, a coating provided on the outer periphery of the rotating component, a cylinder 16 and a support column 15 fixedly installed at the bottom of the metering machine body 1, a weighing trough 12 rotatably connected to the top of the cylinder 16 and the support column 15, a plurality of pressure sensors 13 fixedly installed inside the weighing trough 12, a tray 14 fixedly installed on the side of the pressure sensor 13 away from the weighing trough 12, the motor 3 drives the rotating component to work, the rotating component is used to control the feeding of materials, the cylinder 16 can push one end of the weighing trough 12 to rise or fall, changing the tilt angle of the weighing trough 12, the support column 15 provides stable support, when the material falls onto the tray 14 in the weighing trough 12, the pressure sensor 13 can sense the weight of the material in real time and feed the signal back to the control system to realize quantitative weighing;

[0031] The top of the metering machine body 1 is rotatably connected to a first screen 20 and a second screen 21. Springs 19 are fixedly installed at the bottom of both the first screen 20 and the second screen 21. The bottom of the springs 19 is fixedly connected to the inside of the metering machine body 1. A second guide plate 18 is provided at the bottom of both the first screen 20 and the second screen 21. The second guide plate 18 is fixedly installed inside the metering machine body 1. Waste outlets are opened on both sides of the metering machine body 1. One side of the second guide plate 18 is close to the waste outlet. The first screen 20 and the second screen 21 can screen the materials entering the metering machine. The springs 19 play a buffering role, allowing the screens to vibrate and screen the materials. Materials that do not meet the specifications are discharged from the waste outlet through the second guide plate 18.

[0032] The rotating assembly includes a support tube 2, a fixed shaft 4, a first bevel gear 5, and a second bevel gear 6. The output end of the motor 3 is coaxially and fixedly connected to the first bevel gear 5. The second bevel gear 6 is located on one side of the first bevel gear 5. The teeth of the first bevel gear 5 and the second bevel gear 6 mesh. After the motor 3 starts, its output end drives the first bevel gear 5 to rotate. Since the teeth of the first bevel gear 5 and the second bevel gear 6 mesh, the rotation of the first bevel gear 5 will drive the second bevel gear 6 to rotate, thereby transmitting the power of the motor 3 to the subsequent components, realizing the power input and initial transmission of the rotating assembly. The support tube 2 is fixedly installed inside the metering machine body 1. One side of the support tube 2 is rotatably connected to the fixed shaft 4 through a bearing. The fixed shaft 4 is coaxially and fixedly connected inside the second bevel gear 6. The support tube 2 provides a support for the fixed shaft 4. The mounting position and support are provided. The fixed shaft 4 is rotatably connected to the support tube 2 via bearings, allowing the fixed shaft 4 to rotate flexibly on the support tube 2. When the second bevel gear 6 rotates under the drive of the first bevel gear 5, it will drive the coaxially fixed fixed shaft 4 to rotate together, ensuring the stability of power transmission. The rotating assembly also includes a first gear 7 and a second gear 8. The first gear 7 is coaxially fixedly connected to the top of the fixed shaft 4, and the second gear 8 is set on the top of the support tube 2. The tooth surfaces of the first gear 7 and the second gear 8 mesh. When the fixed shaft 4 rotates, it will drive the coaxially fixed first gear 7 to rotate. Since the tooth surfaces of the first gear 7 and the second gear 8 mesh, the rotation of the first gear 7 will drive the rotation of the second gear 8, realizing further power transmission and speed change, and changing the rotation speed and direction of subsequent components.

[0033] The rotating assembly also includes a connecting rod 9, a fixing block 10, and a sealing plate 11. The fixing block 10 is fixedly installed on the top of the support tube 2. A second gear 8 is rotatably connected to the outer circumference of the fixing block 10. Multiple connecting rods 9 are rotatably connected to the top of the second gear 8. When the second gear 8 rotates under the drive of the first gear 7, the rotation of the second gear 8 causes the connecting rods 9 to move, converting the rotational motion of the second gear 8 into the swinging motion of the connecting rods 9. The end of the connecting rod 9 away from the second gear 8 is rotatably connected to the sealing plate 11. One end of the sealing plate 11 is rotatably connected to the top of the fixing block 10. Multiple sealing plates 11 cooperate with each other. When the connecting rod 9 swings, it will drive the sealing plates 11 rotatably connected to it. Rotating around the rotating connection point at the top of the fixed block 10, multiple sealing plates 11 cooperate with each other and are opened or closed by the drive of the connecting rod 9, thereby controlling the material feeding channel and realizing the function of quantitative material feeding. A support pipe 2 is set directly above the weighing tank 12, and a discharge port is opened on one side of the bottom of the metering machine body 1. A first guide plate 17 is set on the inner side of the discharge port. The end of the first guide plate 17 away from the metering machine body 1 cooperates with the weighing tank 12. When the rotating component controls the material feeding, the material falls into the area directly above the weighing tank 12 through the channel, and then falls into the weighing tank 12 for weighing. After weighing is completed, the cylinder 16 pushes the weighing tank 12 to tilt, so that the weighed material is discharged from the discharge port along the first guide plate 17, completing the quantitative weighing and discharge process of the material.

[0034] The working process of this utility model:

[0035] Step 1: After the material enters the device from the top of the metering machine body 1, it first falls on the inclined first screen 20. Due to the action of the spring 19 at the bottom of the first screen 20, the screen vibrates. Under the combined action of vibration and its own gravity, the material disperses and rolls on the first screen 20. Larger particle size high-quality material is intercepted on the first screen 20, while smaller particle size inferior material falls through the first screen 20 to the second guide plate 18 and then falls out of the device. Qualified high-quality material falls through the first screen 20 onto the inclined second screen 21. The second screen 21 also vibrates under the action of the spring 19 to further screen the material. Smaller particle size inferior material slides out of the device through the second screen 21 via the second guide plate 18. Qualified material screened by the first screen 20 and the second screen 21 continues to fall.

[0036] Step 2: Motor 3 starts, and its output end drives the first bevel gear 5, which is fixedly connected to the same axis, to rotate. The first bevel gear 5 meshes with the tooth surface of the second bevel gear 6, thereby driving the second bevel gear 6 to rotate. The second bevel gear 6 drives the fixed shaft 4, which is fixedly connected to the same axis, to rotate on the support tube 2. The first gear 7 at the top of the fixed shaft 4 rotates accordingly. The first gear 7 meshes with the tooth surface of the second gear 8, thereby driving the second gear 8 to rotate. When the second gear 8 rotates, the multiple connecting rods 9 rotatably connected to its top swing. The connecting rods 9 drive the sealing plate 11, which is rotatably connected to it, to rotate around the rotating connection point with the top of the fixed block 10. The multiple sealing plates 11 cooperate to open, allowing qualified materials to fall into the area directly above the weighing tank 12 through the feeding channel, and then into the weighing tank 12.

[0037] Step 3: After the qualified material falls onto the tray 14 in the weighing tank 12, multiple pressure sensors 13 in the weighing tank 12 sense the weight of the material in real time. When the required weight is reached, the pressure sensors 13 send a signal back to the control system. When the weight of the material reaches the preset value, the control system controls the motor 3 to rotate, the rotating component to stop working, the sealing plate 11 to close, the material feeding to stop, the cylinder 16 to start, push one end of the weighing tank 12 to descend, change the tilt angle of the weighing tank 12, and the weighed material is discharged from the discharge port on one side of the bottom of the metering machine body 1 along the first guide plate 17, thus completing the quantitative weighing and discharge process of the material.

[0038] 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.
