Description

Technical Field

[0001] This utility model relates to the field of flour packaging technology, specifically a bagged flour packaging device. Background Technology

[0002] Flour is a powdery substance made from wheat and is the main ingredient in making a variety of pasta dishes. After production, flour is often packaged in bags to facilitate subsequent transportation or storage.

[0003] In the prior art, patent publication number CN216509244U discloses a multi-station flour quantitative packaging device, including a base and multiple weighing modules disposed at the end of the base. The base is provided with a feeding hopper with at least two conveying chambers inside, located between the multiple weighing modules. A material conveyor is provided in the feeding hopper. A material additive for feeding material to the conveying chamber is rotatably provided at the bottom of the feeding hopper. A discharge pipe with a valve is provided at the top of the conveying chamber and faces the weighing module. The weighing module is provided with a placement frame that is open at the top and sides. The top of the placement frame is provided with a fixed plate that moves in the vertical direction. At least two arc-shaped clamps with first elastic elements and arranged horizontally are provided in the middle of the placement frame. The bottom of the placement frame is provided with a horizontal support through a second elastic element.

[0004] This type of multi-station flour quantitative packaging device has the following disadvantages: After the flour is bagged, the flour inside the bag falls naturally, leaving gaps and air between the flour particles. Direct packaging will result in too much air inside the flour bag, making it prone to breakage when squeezed during transportation. Therefore, after bagging, the operator needs to manually shake the flour bag to expel the air inside, increasing the operator's workload. To address this, we propose a bagged flour packaging device. Utility Model Content

After the flour is filled, the flour bag is shaken up and down by a shaking mechanism to compact the flour inside the bag and expel the air between the flour particles. This reduces the burden on the operator and improves the efficiency of flour bagging and packaging, effectively solving the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bagged flour packaging device, including a support frame, a fixing ring fixedly connected to the upper end of the support frame, a hopper one fixedly connected inside the fixing ring, an adjustable mounting block provided in the middle of the front surface of the support frame, a hopper two fixedly connected inside the mounting block, a pressure sensor fixedly connected to the lower side of the support frame, and also including a shaking mechanism.

The upper end of the connecting rod is slidably connected to the track groove. Through the shaking mechanism, after the flour bag is filled, the flour bag is directly shaken up and down to compact the flour inside the flour bag and expel the air between the flour particles inside the flour bag. This reduces the burden on the operator and improves the efficiency of flour bagging and packaging.

[0008] Furthermore, a microcontroller is installed on the outside of the support frame. The input terminal of the microcontroller is electrically connected to an external power source to control the operation of electrical appliances.

[0010] Furthermore, rotating rods are rotatably connected to both the left and right surfaces of the mounting block, and protrusions are fixedly connected to the middle of the outer surface of each rotating rod. Clamping blocks are also fixedly connected to the outer surface of each rotating rod to clamp the flour bag.

[0011] Furthermore, the outer surface of the mounting block is rotatably connected to symmetrically distributed electric push rods. The lower side of the telescopic end of each electric push rod is rotatably connected to the upper surface of the adjacent protrusion on the same side.

[0013] Furthermore, an air outlet is fixedly connected to the outer surface of the second hopper to balance the internal air pressure of the flour bag when flour is being filled.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This bagged flour packaging device has the following advantages:

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6This embodiment provides a technical solution: a bagged flour packaging device, including a support frame 1, a fixing ring 4 fixedly connected to the upper end of the support frame 1, a hopper 6 fixedly connected inside the fixing ring 4, an adjustable mounting block 7 provided in the middle of the front surface of the support frame 1, a second hopper 8 fixedly connected inside the mounting block 7, an air outlet 12 fixedly connected to the outer surface of the second hopper 8, the opening of the flour bag being fitted onto the lower side of the outer surface of the second hopper 8, a pressure sensor 14 fixedly connected to the lower side of the support frame 1, and a microcontroller 2 disposed outside the support frame 1, the input end of the microcontroller 2 being electrically connected to an external power supply, the pressure sensor 14 and the microcontroller... 2. Two-way electrical connection: Rotating rods 9 are rotatably connected to both the left and right surfaces of mounting block 7. A protrusion is fixedly connected to the middle of the outer surface of each rotating rod 9. A clamping block 11 is fixedly connected to the outer surface of each rotating rod 9. Symmetrically distributed electric push rods 10 are rotatably connected to the outer surface of mounting block 7. The lower side of the telescopic end of each electric push rod 10 is rotatably connected to the upper surface of the adjacent protrusion on the same side. The input end of each electric push rod 10 is electrically connected to the output end of microcontroller 2. Controlling microcontroller 2 to start electric push rod 10 causes the telescopic end of electric push rod 10 to extend, pushing the protrusion to move, causing rotating rod 9 to rotate, which in turn drives clamping block 11 to rotate, causing clamping block 11 to move towards the material. The second hopper moves in the direction of 8 to fix the flour bag. When the flour in the bag reaches a certain weight, the pressure sensor 14 sends a signal to the microcontroller 2, causing the microcontroller 2 to control the telescopic end of the electric push rod 15 to retract, driving the movable baffle 13 to move upward near the end of the first hopper 6 to block the discharge port at the lower end of the first hopper 6. The left and right sides of the inside of the first hopper 6 are rotatably connected to the rotating shaft 17, and the outer surface of the rotating shaft 17 is fixedly connected to the movable baffle 13. The front and rear surfaces of the first hopper 6 are fixedly connected to the electric push rod 15, and the lower side of the telescopic end of the electric push rod 15 is fixedly connected to the movable rod 16. The left side of the movable rod 16... Both ends of the right side are rotatably connected to connecting rod 18. The lower ends of connecting rod 18 are rotatably connected to the vertically adjacent movable baffle 13 on the same side. The input end of electric push rod 15 is electrically connected to the output end of microcontroller 2. When microcontroller 2 is operated, electric push rod 15 is started. The telescopic end of electric push rod 15 extends, driving movable rod 16 to move downward, driving connecting rod 18 to move downward, so that the end of movable baffle 13 near hopper 6 rotates around the rotating shaft 17, so that the end of movable baffle 13 near hopper 6 moves downward. At this time, flour is injected into flour bag through hopper 28 through the lower end of hopper 6. It also includes a shaking mechanism 5.

[0025] The wobbling mechanism 5 includes a drive shaft 51, a turntable 52, a track groove 53, a connecting rod 54, and a slider 55. The drive shaft 51 is rotatably connected to the inside of the support frame 1. The turntable 52 is fixedly connected to the middle of the outer surface of the drive shaft 51. The track groove 53 is formed on the front surface of the turntable 52. The slider 55 is slidably connected to the inside of the support frame 1. The connecting rod 54 is fixedly connected to the upper surface of the slider 55. The upper end of the connecting rod 54 is slidably connected to the track groove 53. The motor 3 is fixedly connected to the rear surface of the support frame 1. The front end of the output shaft of the motor 3 is connected to the motor 3. The motor 3 is fixedly connected to the rear end of the drive shaft 51. The input end of the motor 3 is electrically connected to the output end of the microcontroller 2. When the microcontroller 2 is operated, the motor 3 is started. The output shaft of the motor 3 rotates, which drives the drive shaft 51 to rotate, causing the turntable 52 to rotate and the track groove 53 to move. This causes the connecting rod 54 to move up and down, which in turn drives the slider 55 to move up and down, causing the mounting block 7 to move up and down, which in turn drives the hopper 8 to move up and down, causing the flour bag filled with flour to move up and down. This causes the flour inside the flour bag to be compacted, thereby expelling the air in the gaps between the flour particles inside the flour bag.

[0026] The working principle of the bagged flour packaging device provided by this utility model is as follows: When using this bagged flour packaging device to package bagged flour, the opening of the flour bag is fitted onto the lower side of the outer surface of the hopper 2 8. The microcontroller 2 is controlled to start the electric push rod 10. The telescopic end of the electric push rod 10 extends, pushing the protrusion to move, causing the rotating rod 9 to rotate, which in turn drives the clamping block 11 to rotate, causing the clamping block 11 to move towards the hopper 2 8, thereby fixing the flour bag and injecting flour into the hopper 1 6. The microcontroller 2 is then operated to start the electric push rod 2 15. The telescopic end of the electric push rod 2 15 extends, driving the movable rod 16 to move downward, which in turn drives the connecting rod 2 18 to move downward, causing the movable baffle 13 near the hopper 1 6 to rotate around the rotating shaft 17, causing the movable baffle 13 near the hopper 1 6 to move downward. At this time, the flour is injected into the flour bag through the lower end of hopper 16 and hopper 28. When the flour in the bag reaches a certain weight, the pressure sensor 14 sends a signal to the microcontroller 2, causing the microcontroller 2 to control the extension end of the electric push rod 2 15 to retract, driving the movable baffle 13 to move upward near the end of hopper 16, thereby blocking the discharge port at the lower end of hopper 16. At this time, the microcontroller 2 is operated to start the motor 3. The output shaft of the motor 3 rotates, driving the transmission shaft 51 to rotate, causing the turntable 52 to rotate, causing the track groove 53 to move, thereby causing the connecting rod 1 54 to move up and down, driving the slider 55 to move up and down, causing the mounting block 7 to move up and down, driving the hopper 2 8 to move up and down, causing the flour bag full of flour to move up and down, thereby compacting the flour inside the flour bag and expelling the air in the gaps between the flour inside the flour bag.

[0027] It is worth noting that in the above embodiments, the microcontroller 2 is selected as AT89C52, the motor 3 is selected as BLDC-045-28, the electric actuator 10 is selected as NKLA22, the pressure sensor 14 is selected as PK5722, and the electric actuator 2 is selected as YNT-04.
