[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] A flour quantitative weighing and bagging device, combined with Figures 1 to 2 As shown, it includes a base plate 1, on which a vertical box 2 is erected vertically upward. A flour silo 3 is set on the top of the vertical box 2. The flour silo 3 is used to hold flour, and a discharge port 31 is set at the bottom of the flour silo 3. The discharge port 31 is funnel-shaped and a discharge control valve is set on the discharge port 31. The discharge control valve is used to control the opening and closing of the discharge port.

[0021] The vertical box 2 is equipped with a limiting seat 4 located below the flour silo 3. A connecting seat 5 is provided in the limiting seat 4. The connecting seat 5 will not detach from the limiting seat 4 under the limiting seat 4. This is achieved by opening a slot on the connecting seat 5 and setting a locking block on the limiting seat 4 to assemble with the slot. A weighing sensor is set between the connecting seat 5 and the limiting seat 4. All equipment and items set on the connecting seat 5 can have their overall weight measured by the weighing sensor.

[0022] The end of the connecting seat 5 away from the vertical box 2 is connected to an upper mounting plate 6, which is located below the discharge port 31 and is horizontally positioned. Two vibrating cylinders 7 are respectively located on both sides of the discharge port 31 on the upper mounting plate 6. By extending and retracting the vibrating cylinders 7, the equipment and items connected to the vibrating cylinders 7 can be raised and lowered.

[0023] The telescopic rod of the vibrating cylinder 7 is positioned downwards and connected to a bag opening support mechanism 8, which is used to support the opening of the flour bag. For example... Figures 3 to 4 As shown, the bag opening support mechanism 8 includes a horizontally mounted lower mounting plate 81 connected to the telescopic rod end of the vibrating cylinder 7. A pair of support claws 82 are positioned opposite each other on the lower surface of the lower mounting plate 81. The tops of the support claws 82 are hinged to the lower mounting plate 81. A horizontally mounted support drive cylinder 83 is positioned in the middle of the support claws 82. Both ends of the support drive cylinder 83 are hinged to the support claws 82 on both sides. The opening and closing of the bottom of the support claws 82 is achieved by extending and retracting the telescopic rod of the support drive cylinder 83. When flour needs to be bagged, the flour bag opening is manually opened, covering the bottom of the support claws 82. The telescopic rod of the support drive cylinder 83 is then extended, opening the bottom of the support claws 82 and thus closing the flour bag opening from the inside.

[0024] The bag opening support mechanism 8 includes a longitudinally positioned discharge pipe 19 located directly below the discharge port 31. A cloth bag 9 is placed between the discharge pipe 19 and the discharge port 31, providing a flexible connection between them. The upper mounting plate 6 has a through hole for the cloth bag 9 to pass through. A support ring is located at the bottom of the discharge port 31, inside the cloth bag 9 to support it. During flour filling, a weighing sensor continuously monitors the total mass of the connecting seat 5, mounting plate 6, vibrating cylinder 7 mounted on the mounting plate 6, bag opening support mechanism 8, discharge pipe 19, flour bag, and the flour inside. When the difference between the value monitored by the weighing sensor and the weight measured by the weighing sensor after the empty flour bag is supported equals the weight of the flour, the quantitative weighing and bagging of the flour is complete, and the discharge control valve is closed to stop the discharge. Then, the telescopic rod of the vibrating cylinder 7 is driven to extend and retract, causing the flour bag to move up and down, thus compacting the flour inside.

[0025] like Figure 5 As shown, a horizontally arranged clamping hoop 84 is provided on the inner bottom side of the supporting claw 82. The clamping hoop 84 is used to clamp the material discharge pipe 19 from the bottom side wall of the discharge pipe 19 after the supporting claw 82 is closed. The clamping hoop 84 includes a semi-annular section 842 adapted to the outer wall of the discharge pipe 19 and straight sections 841 located on both sides of the semi-annular section 842. The inner side of the straight section 841 is provided with an abutment block 85, and the abutment block 85 on the bottom straight section 841 of the supporting claw 82 abuts after the supporting claw 82 is closed.

[0026] A base plate 1 is equipped with a height-adjustable base support 11. When the flour bag is filled with flour, the base support 11 supports the flour bag from the bottom. Specifically, two support rods 10 are erected on the upright box 2 below the limiting seat 4. The side of the base support 11 closest to the support rods 10 is slidably assembled with the support rods 10, thereby realizing the lifting and lowering of the base support 11. The bottom of the support rods 10 is connected to a threaded sleeve 12 through an external thread. The threaded sleeve 12 is located below the base support 11. The threaded sleeve 12 is used to position the height of the base support 11 and support the base support 11 from the bottom. By adjusting the height of the base support 11, it can accommodate flour bags of different lengths while keeping the extension length of the vibrating cylinder 7 fixed.

[0027] To ensure the stability of the base support 11, the four corners of the bottom of the base support 11 are threaded with support threaded legs 13. By rotating the support threaded legs 13, the length of the base support 11 can be adjusted, thereby stabilizing the base support 11.

[0028] The side wall of the discharge port 31 is connected to a dust collection pipe 18 through a dust outlet. The other end of the dust collection pipe 18 is connected to a dust treatment system, which can collect the dust generated during the weighing and bagging of flour and avoid environmental pollution.

[0029] The bottom of the base plate 1 is provided with a support leg 14, which is used to support the entire device.

[0030] A control box 15 is installed on the upright box 2. Inside the control box 15 is a PLC controller. The input terminal of the PLC controller is connected to the output terminal of the weighing sensor. The output terminal of the PLC controller is connected to the controlled terminals of the discharge control valve, the vibration cylinder 7, and the opening drive cylinder 83 of the bag opening mechanism 8, respectively, thereby realizing the automatic control of the flour quantitative weighing and bagging process. The control box 15 is equipped with a display screen 16 and control buttons 17. The output terminal of the control buttons 17 is connected to the input terminal of the PLC controller, and the output terminal of the PLC controller is connected to the input terminal of the display screen 16. The display screen 16 and control buttons 17 are used for human-machine interaction.

[0031] The working principle of this utility model is as follows: The flour bag is placed under the bottom of the bag opening support mechanism 8, and the extension rod of the support drive cylinder 83 is extended to open the flour bag opening using the support claw 82. The bottom support 11 is adjusted to a suitable height according to the length of the flour bag, ensuring it does not contact the bottom of the flour bag. The PLC controller receives the initial value from the weighing sensor and opens the discharge control valve. Flour falls into the bag through the discharge port 31, the cloth bag 9, and the discharge pipe 19. The weighing sensor monitors the weight in real time and feeds it back to the PLC controller. When the difference between the monitored weight value and the initial value approaches the set flour weight... When the set flour weight value is reached, the PLC controller controls the discharge control valve to reduce its opening. When the set flour weight value is reached, the PLC controller closes the discharge control valve. The vibrating cylinder 7 is started to lift and lower the flour bag, thereby compacting the flour in the flour bag. After compaction, the telescopic rod of the vibrating cylinder 7 extends, and the bottom of the flour bag abuts against the bottom support 11. The telescopic rod of the support drive cylinder 83 retracts, and then the telescopic rod of the vibrating cylinder 7 retracts, and the support drive cylinder 83 returns to its original position away from the flour bag, completing the quantitative weighing and bagging of flour. This method is not only highly accurate but also highly efficient.
