Abstract

This invention relates to the field of food processing technology, specifically to a fully automatic remote-controlled dough mixing equipment, including a dough hopper, a feeder, an acceleration chamber, a flour adding mechanism, a fan, a dough mixing mechanism, and an automatic temperature-controlled water dispenser. The dough mixing mechanism can precisely control the rotation and straightening of the dough hopper. Specifically, when the dough hopper rotates, it stops rotating when the switch baffle contacts limit switch a or limit switch b; when the dough hopper straightens, it stops rotating when the proximity switch baffle contacts proximity switch a, and the stirring mechanism can only operate when the proximity switch baffle contacts proximity switch b. This avoids the problem of manual adjustment required if the dough hopper is not fully rotated, and also avoids the risk of starting the stirring operation before the dough hopper is fully rotated, ensuring safety and reliability. This invention automates the entire process from flour adding to dough mixing, improving the overall automation level of the equipment, achieving fully automatic remote control, and significantly increasing production efficiency.

Description

Technical Field

[0001] This invention relates to the field of food processing technology, and more specifically to a fully automatic remote-controlled dough kneading device. Background Technology

[0002] With increasing demands for food safety and quality, as well as a pursuit of production efficiency, the demand for fully automated, remotely controlled dough mixing equipment is constantly growing. Simultaneously, the rapid development of the catering industry has created a larger market space for this equipment. Modern automatic dough mixers can control the water-to-flour ratio, adjusting the amount used in this process through an electronic system. This control method not only improves the quality of the dough but also ensures consistency in each mixing cycle, reducing the need for manual operation and increasing production efficiency. However, some problems still exist. For example, after the dough mixing process is complete, it needs to be removed from the mixing hopper. Existing dough mixers cannot effectively control the degree of hopper rotation, and operators may still need to make manual adjustments, thus failing to achieve fully automated production. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and to propose a fully automatic remote control dough mixing device that can precisely control the degree of dough hopper rotation, realize fully automated operation, and improve production efficiency.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A fully automatic remote-controlled dough-making device, comprising:

[0006] A flour silo is used to store flour.

[0007] The feeder is connected to the bottom of the flour bin, and flour falls from the flour bin to the feeder.

[0008] The acceleration chamber is connected to the bottom of the feeder;

[0009] The powder feeding mechanism is connected to the acceleration chamber via a conveying pipe;

[0010] The blower is connected to the acceleration chamber and provides a pressurized air source for the acceleration chamber. The pressurized air source transports the flour to the flour adding mechanism through the conveying pipe.

[0011] A dough mixing mechanism, connected to a flour adding mechanism, is used for dough mixing.

[0012] An automatic temperature-controlled water dispenser, connected to the dough-kneading mechanism, is used to add water to the dough-kneading mechanism;

[0013] The dough mixing mechanism includes a frame and further includes:

[0014] The dough hopper is rotatably connected to both sides of the frame. A stirring mechanism is installed inside the hopper. The stirring shaft of the stirring mechanism is connected to the output end of a reducer mounted on the frame. The reducer drives the stirring mechanism to achieve automatic dough kneading. One end of the dough hopper is connected to a worm gear, which meshes with a horizontal worm located below it and mounted on the frame. One end of the worm is connected to a tipping pulley, which is connected to a tipping motor wheel via a transmission belt. The tipping motor wheel is mounted on the output end of the tipping motor. When the tipping motor is started, the tipping pulley rotates via the transmission belt, causing the worm to rotate, which in turn drives the worm gear to rotate. The worm gear then causes the dough hopper to flip.

[0015] The switch baffle is fixedly installed on the upper side of the worm gear.

[0016] Two limit switches are provided and installed on the frame. They are limit switch a and limit switch b. Limit switch a and limit switch b are located on both sides of the switch baffle. When the switch baffle contacts limit switch a or limit switch b, the dough bucket stops rotating.

[0017] The proximity switch baffle is fixedly installed on the lower side of the worm gear.

[0018] Two proximity switches are provided, namely proximity switch a and proximity switch b. Proximity switches a and b are fixed on the arc-shaped mounting plate G16, which is mounted on the frame.

[0019] Furthermore, the mixing hopper stops rotating when the proximity switch a contacts the proximity switch b; the stirring mechanism can only operate when the proximity switch b is in contact with the proximity switch b.

[0020] Furthermore, a stop mechanism is provided on the frame. The stop mechanism includes a fixed base, a stop support, a stop cylinder, and a stop block. The fixed base is mounted on the frame, the stop support is mounted on the fixed base and can rotate relative to the fixed base, and the stop block is mounted on the stop support and can rotate with the stop support to prevent the noodle bucket from tipping over. The stop cylinder is mounted on the frame, and the piston rod of the stop cylinder is fixed to the stop support to drive the stop support to rotate. When the noodle bucket is in a vertical position, the stop block just prevents the noodle bucket from tipping over. When it is necessary to tip the noodle bucket, the stop support needs to be rotated by the stop cylinder to move the stop block to one side of the noodle bucket to avoid preventing the noodle bucket from tipping over.

[0021] Furthermore, a top cover is installed on the top of the flour hopper, and opening cylinders are installed on both sides of the frame respectively. The piston rod of the opening cylinder is connected to the end of the top cover and is used to open and close the top cover.

[0022] Furthermore, an opening limit switch and a closing limit switch are respectively provided at both ends of the opening cylinder.

[0023] Furthermore, the powder adding mechanism includes a base frame and also includes:

[0024] The weighing module is fixed to the base frame;

[0025] The weighing hopper is connected to the weighing module and has a powder filling port on the top.

[0026] The conveying auger is located at the bottom of the weighing hopper and is used to convey flour inside the weighing hopper.

[0027] A geared motor, connected to the rear end of the conveyor auger, is used to drive the conveyor auger;

[0028] A flour limit switch is located at the upper front end of the conveyor auger;

[0029] A pneumatic valve is located at the lower front end of the conveyor auger. A flexible connection is located at the bottom of the valve, and a discharge port is located at the bottom of the connection. Accurate weighing by a weighing module and timely closure of the pneumatic valve to stop discharge effectively prevents issues such as excessive or insufficient powder addition.

[0030] Furthermore, a dust collector is installed on the top of the weighing silo, which plays a role in dust removal during the flour addition process.

[0031] Furthermore, a cleaning port is provided at the bottom of the weighing hopper, which is connected to the conveying auger to discharge flour residue in the weighing hopper and the conveying auger.

[0032] Furthermore, an air hammer is installed on the side of the weighing hopper to strike the hopper and ensure that the flour falls smoothly.

[0033] Furthermore, a stirring shaft is installed inside the flour hopper, and stirring blades are installed on the stirring shaft for stirring the flour inside the flour hopper. The stirring shaft is a hollow cylindrical structure with an open top. The upper end of the stirring shaft is connected to the cover plate of the flour hopper via a bearing. The cover plate is detachably installed on the top of the flour hopper. The stirring shaft is driven to rotate by a drive mechanism. A rigid spring is fixed to the bottom of the inner side of the stirring shaft. The top of the rigid spring is fixed to a moving block. The outer side of the moving block is in contact with the inner wall of the stirring shaft. An opening 1 is opened on the stirring shaft. The moving block can completely seal the opening 1 under the support of the rigid spring. A movable tube is sleeved inside the stirring shaft. The movable tube is open at the top and hollow inside. An opening 2 is provided on the side of the movable tube to cooperate with the opening 1. When the movable tube is pressed down, the movable tube presses down on the moving block until the opening 2 on the movable tube overlaps (partially or completely overlaps) with the opening 1 on the stirring shaft. The flour in the flour hopper can then enter the movable tube through the opening 1 and the opening 2. Then, the movable tube is lifted up to sample the flour inside the flour hopper, enabling rapid sampling inspection of the flour in the flour hopper. When the moving tube is lifted upwards, the moving block returns to its original position under the action of the rigid spring, sealing the opening again to prevent flour from entering the mixing shaft.

[0034] Technical effects of the present invention:

[0035] Compared with existing technologies, the fully automatic remote-controlled dough mixing equipment of this invention can precisely control the rotation and straightening of the dough bucket. Specifically, when the dough bucket is rotating, it stops rotating when the switch baffle contacts limit switch a or limit switch b; when the dough bucket is straightening, it stops rotating when the proximity switch baffle contacts proximity switch a, and the stirring mechanism can only operate when the proximity switch baffle contacts proximity switch b. This avoids the problem of manual adjustment required when the dough bucket is not rotated properly, and also avoids the risk of starting the stirring operation when the dough bucket is not rotated properly, ensuring safety and reliability. This invention automates the entire process from adding flour to mixing dough, improving the automation level of the entire equipment, achieving fully automatic remote control, and significantly improving production efficiency.

[0053] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0054] Example 1:

[0055] like Figure 1As shown, this embodiment relates to a fully automatic remote-controlled dough mixing device, including a dough hopper A, a feeder B, an acceleration chamber C, a flour adding mechanism D, a conveying pipe E, a fan F, a dough mixing mechanism G, an automatic temperature-controlled water dispenser H, and an extraction chamber K. The dough hopper A is used to store flour; the feeder B is connected to the bottom of the dough hopper A, and flour falls from the dough hopper A to the feeder B; the acceleration chamber C is connected to the bottom of the feeder B; the flour adding mechanism D is connected to the acceleration chamber C via the conveying pipe E; the fan F is connected to the acceleration chamber C, providing a pressurized air source for the acceleration chamber C, and the pressurized air source conveys the flour to the flour adding mechanism D via the conveying pipe E; the dough mixing mechanism G is connected to the flour adding mechanism D and is used for dough mixing; the automatic temperature-controlled water dispenser H is connected to the dough mixing mechanism G and is used to add water to the dough mixing mechanism G; the feeder B is connected to the dough hopper A via the extraction chamber K, and the feeder B adjusts its inlet and outlet pressures through the extraction chamber K to facilitate the entry of flour into the acceleration chamber C.

[0056] like Figure 2-7 As shown, the dough mixing mechanism G includes a frame G1, a dough hopper G2, a stirring mechanism, a stop mechanism, a reducer G3, a worm gear G5, a worm G6, a tipping motor G10, a switch stop plate G11, a limit switch aG1201, a limit switch bG1202, a proximity switch stop plate G13, a proximity switch aG14, a proximity switch bG15, and a top cover G21.

[0057] The frame G1 includes a main frame G101 and protective covers G102 disposed on both sides of the main frame G101, the protective covers G102 serving a protective function.

[0058] A cover G21 is provided above the flour hopper G2. The cover G21 has a flour inlet G25 and a water inlet G26. The flour inlet G25 is connected to the flour adding mechanism D and is used to add flour into the flour hopper G2. The water inlet G26 is connected to the automatic temperature-controlled water dispenser H and is used to add water into the flour hopper G2.

[0059] The dough hopper G2 is rotatably connected to both sides of the frame G1 at both ends. A stirring mechanism is installed inside the dough hopper G2. The stirring shaft A1 of the stirring mechanism is connected to the output end of a reducer G3 mounted on the frame G1 via a coupling G4. The input end of the reducer G3 is connected to the output end of the main motor G27 mounted on the frame G1 via a sprocket or belt, allowing the reducer G3 to drive the stirring mechanism to perform dough kneading. The other end of the dough hopper G2 is connected to a worm gear G5, which meshes with a horizontal worm G6 located below it and mounted on the frame G1. One end of the worm G6 is connected to a tipping pulley G7, which is connected to a tipping motor wheel G9 via a transmission belt G8. The tipping motor wheel G9 is mounted on the output end of a tipping motor G10. When the tipping motor G10 is started, the tipping pulley G7 rotates via the transmission belt G8, causing the worm G6 to rotate, which in turn rotates the worm gear G5, causing the dough hopper G2 to tilt.

[0060] The switch baffle G11 is fixedly installed on the upper side of the worm gear G5. Two limit switches are provided, both installed on the frame G1, namely limit switch aG1201 and limit switch bG1202. Limit switches aG1201 and bG1202 are located on both sides of the switch baffle G11. When the switch baffle G11 contacts the limit switch aG1201 or the limit switch bG1202, the dough bucket G2 stops rotating.

[0061] The proximity switch baffle G13 is fixedly installed on the lower side of the worm gear G5. Two proximity switches are provided: proximity switch aG14 and proximity switch bG15, which are fixed to the arc-shaped mounting plate G16, which is mounted on the frame G1. When proximity switch aG14 contacts proximity switch baffle G13, the flour hopper G2 stops rotating; when proximity switch bG15 contacts proximity switch baffle G13, the stirring mechanism can operate. The cooperation between proximity switches aG14 and bG15, and the linkage between proximity switch bG15 and the stirring mechanism, ensures that the stirring mechanism can perform stirring operations even when the flour hopper G2 is rotated into position, guaranteeing the safety and effectiveness of the operation.

[0062] The stop mechanism is located on the frame G1 near the reducer G3. The stop mechanism includes a fixed base G17, a stop support G18, a stop cylinder G19, and a stop G20. The fixed base G17 is mounted on the frame G1. The stop support G18 is mounted on the fixed base G17 and can rotate relative to the fixed base G17. The stop G20 is mounted on the stop support G18 and can rotate with the stop support G18, used to prevent the bucket G2 from tipping over. The stop cylinder G19 is mounted on the frame G1, and the piston rod of the stop cylinder G19 is fixed to the stop support G18, used to drive the stop support G18 to rotate. When the noodle bucket G2 is in a vertical position, the stop block G20 just blocks the noodle bucket G2 from turning. When it is necessary to turn the noodle bucket G2, the stop block support G18 needs to be rotated by the stop block cylinder G19 first, so as to move the stop block G20 to one side of the noodle bucket G2 and avoid blocking the noodle bucket G2 from turning.

[0063] The upper cover G21 is equipped with an opening cylinder G22. Specifically, a set of opening cylinders G22 is installed on each side of the frame G1. The piston rod of the opening cylinder G22 is connected to the end of the upper cover G21 for opening and closing the upper cover G21. Preferably, two sets of opening cylinders G22 are installed on the same side, which can more smoothly raise and lower the upper cover G21. An opening limit switch G23 and a closing limit switch G24 are respectively provided at both ends of the opening cylinder G22. Specifically, as shown... Figure 6As shown, the opening limit switch G23 and closing limit switch G24 are located at the upper and lower limits of the opening cylinder G22, respectively. The piston inside the opening cylinder G22 is magnetic. When the upper cover G21 is closed, the piston of the opening cylinder G22 is at the lower limit, and due to the magnetic force, the closing limit switch G24 is closed, providing the electrical system with a signal that the upper cover G21 is at the lower limit. Conversely, when the upper cover G21 is open, the piston is at the upper limit, causing the opening limit switch G23 to close, providing the electrical system with a signal that the upper cover G21 is at the upper limit.

[0064] like Figure 8 and Figure 9 As shown, the powder feeding mechanism D includes a base frame D1, a weighing module D2, a weighing hopper D3, a powder feeding port D4, a conveying auger D5, a cleaning port D6, a geared motor D7, a coupling D8, a flour limit switch D9, a pneumatic valve D10, a flexible connection D11, a discharge port D12, a dust collector on the top of the silo D13, and an air hammer D14.

[0065] The weighing module D2 is fixed on the base frame D1.

[0066] The weighing hopper D3 comprises an upper cylinder D301 and a lower cone D302 connected sequentially from top to bottom. The upper cylinder D301 is connected to the weighing module D2. A pneumatic hammer D14 is installed on the outer side of the lower cone D302 to strike the lower cone D302, allowing the flour to fall smoothly. The top of the weighing hopper D3 is equipped with a flour inlet D4 and a dust collector D13, which is located on one side of the flour inlet D4 and is used to remove dust during the flour addition process. A cleaning port D6 is installed at the bottom of the weighing hopper D3.

[0067] The conveying auger D5 is located at the bottom of the weighing hopper D3 and is used to convey flour within the hopper. Specifically, the conveying auger D5 is horizontally positioned, with its rear end connected to a coupling D8, which is mounted on the output shaft of a geared motor D7. The geared motor D7 drives the conveying auger D5 to rotate. A flour limit switch D9 is located at the upper front end of the conveying auger D5, and a pneumatic valve D10 is located at its lower front end. A flexible connection D11 is located at the bottom of the pneumatic valve D10, and a discharge port D12 is located at the bottom of the flexible connection D11. The discharge port D12 is connected to the flour inlet G25. The upper part of the end of the conveying auger D5 closest to the geared motor D7 is connected to the interior of the weighing hopper D3, and the lower part is connected to the cleaning port D6. The cleaning port D6 is normally closed and is opened when it is necessary to discharge flour remaining in the weighing hopper D3 and the conveying auger D5.

[0068] This invention also includes an electrical system, which can be intelligently controlled by a PLC and connected to electrical components such as the tipping bucket motor G10, the stop cylinder G19, the lid opening cylinder G22, the main motor G27, the geared motor D7, the pneumatic valve D10, and the air hammer D14. This system automatically controls the electrical components of the entire equipment, automatically completing a series of automated actions such as dough kneading, tipping the dough bucket G2, returning it to its original position, automatically opening and closing the lid G21, and adding powder, thus achieving automatic dough kneading.

[0069] Working Principle: This invention utilizes a blower F to provide a pressurized air source. Flour falls from the flour hopper A to the rotary feeder B, which then conveys the flour to the acceleration chamber C. The pressurized air source then transports the flour through the conveying pipe E to the weighing hopper D3. The dust collector D13 on the top of the hopper filters the flour dust. When the amount of flour conveyed reaches the set upper limit of the weighing hopper D3, the blower F stops, and the feeder B stops operating. During the operation of the feeder B, the inlet and outlet pressures of the feeder B are adjusted through the extraction chamber K to ensure that the flour smoothly enters the acceleration chamber C.

[0070] The dough mixer sends a kneading signal, and the conveyor auger D5 starts working, conveying the flour from the weighing hopper D3 through the flexible connector D11 into the dough mixer. The weighing module D2 monitors the weight throughout the process. When the set value is reached, the pneumatic valve D10 closes, and the conveyor auger D5 continues to work. When the limit switch D9 senses the flour inside the auger, the conveyor auger D5 stops working. During the operation of the conveyor auger D5, the air hammer D14 rhythmically taps the weighing hopper D3 to prevent the flour from clumping and ensure uniform conveying.

[0071] When the dough mixer sends a dough mixing signal, the automatic temperature-controlled water dispenser H starts after a delay and automatically adds water into the dough mixer's hopper G2. Once the set amount of water is added, the automatic temperature-controlled water dispenser H stops working.

[0072] The dough mixer begins kneading the dough. Throughout the kneading process, the changes in the equipment's electrical parameters are monitored and compared. When the curve of the electrical parameter changes approaches the set curve, the kneading process is complete.

[0073] The top cover G21 opens automatically, the dough hopper G2 of the dough mixer flips automatically, and once it is in place, the mixer works alternately in forward and reverse rotation according to the set mode, discharging the kneaded dough from the dough hopper G2.

[0074] The dough mixer's hopper G2 automatically returns to its original position, and the top cover G21 closes, completing one cycle.

[0075] The entire work process can be controlled remotely via a mini-program or app, and the work status can be monitored in real time.

[0076] Specifically, during operation, flour is added to the dough hopper G2 through the flour inlet G25, and water is added through the water inlet G26. After the flour and water addition is completed, the dough mixer is started and begins automatic operation. During operation, the electrical system automatically controls the main motor G27. After dough mixing is complete, the lid-opening cylinder G22 and the stop cylinder G19 operate simultaneously. The lid-opening cylinder G22 pushes up the upper cover G21 to open the lid, and the stop cylinder G19 pushes the stop support G18 to rotate around the fixed base G17, causing the stop support G18 to disengage from the stop block G20. Then, the tipping motor G10 drives the tipping pulley G7 to rotate via the transmission belt G8. The tipping pulley G7 drives the worm gear G6 to rotate, and the worm wheel G5, driven by the worm gear G6, causes the dough hopper G2 to tilt to the left (e.g., ...). Figure 2 and Figure 7 As shown, when switch baffle G11 contacts limit switch aG1201, the rotation stops. The electrical system controls the main motor G27 to rotate regularly in both forward and reverse directions, discharging the kneaded dough from the dough hopper G2. Then, the tipping motor G10 rotates in the opposite direction. Proximity switch baffle G13, fixed to the worm gear G5, rotates with the dough hopper G2 as it rotates. When proximity switch baffle G13 first passes proximity switch bG15 and continues rotating, it contacts proximity switch aG14, at which point the dough hopper G2 stops rotating. The dough hopper G2 is then in an upright position, with proximity switch baffle G13 simultaneously contacting both proximity switches aG14 and bG15. At this time, the opening cylinder G22 and the stop cylinder G19 work simultaneously. The opening cylinder G22 drives the upper cover G21 to fall, completing the closing of the cover. The stop cylinder G19 drives the stop support G18 to retract. The stop support G18 rotates around the fixed seat G17 and returns to the initial state of adding water and flour, completing one cycle.

[0077] Proximity switch bG15 has a cover-opening stop function. The stirring mechanism can only work continuously after proximity switch bG15 contacts proximity switch b13. Proximity switch aG14 is a detection switch for the upright state of the hopper G2. The upper cover G21 can only be opened and closed when proximity switch b13 contacts proximity switch aG14.

[0078] Figure 2When the noodle bucket G2 needs to be flipped to the right (backwards), the top cover G21 opens, the stop block support G18 opens, the noodle bucket G2 flips backwards, and the switch stop plate G11 contacts the limit switch bG1202. After the flipping action is completed, the noodle bucket G2 can be cleaned as needed. After the cleaning is completed, the noodle bucket G2 flips back to the left. When the proximity switch stop plate G13 contacts the proximity switch aG14, the noodle bucket G2 stops rotating. At this time, the noodle bucket G2 is not in an upright position. Press the left flip button again, and the proximity switch stop plate G13 and proximity switch bG15 will completely disengage. Then press the right flip button, and the proximity switch stop plate G13 first contacts the proximity switch bG15, and then continues to flip. When the proximity switch stop plate G13 contacts the proximity switch aG14, the noodle bucket G2 stops flipping and is in the middle upright position, returning to its original position.

[0079] When the flour feeding mechanism D is in use, flour falls from the bottom of the weighing hopper D3 into the conveying auger D5. The geared motor D7 drives the conveying auger D5 to rotate through the coupling D8, pushing the flour to the front end of the conveying auger D5. The pneumatic valve D10 opens, and the flour is discharged from the outlet D12 through the flexible connection D11. The weighing module D2 monitors the weight of the weighing hopper D3 in real time. When the weight reaches the set value, the pneumatic valve D10 closes, and the conveying auger D5 continues to work. When the flour touches the flour limit switch D9 at the front end of the conveying auger D5, the geared motor D7 stops. The flour is filtered by the dust collector D13 on the top of the silo, preventing it from scattering when being added to the weighing silo D3. Residual flour can be cleaned from the inside through the cleaning port D6. Once the set conveying value is reached, the pneumatic valve D10 closes, and the conveying auger D5 stops adding flour to the dough hopper G2 of the dough mixer, ensuring accurate flour measurement. The reduction motor D7 stops only after the flour contacts the flour limit switch D9. This prevents the conveying auger D5 from becoming overfilled with flour, causing excessive force and mechanical failures such as auger deformation, and ensures that the conveying auger D5 is fully filled with flour, saving time for the next conveying and improving the efficiency of the next flour addition. The air hammer D14 performs regular hammering motions to knock the flour out of the weighing silo D3, preventing flour clumps and ensuring smooth flour descent.

[0080] Example 2:

[0081] like Figure 10-13 As shown, this embodiment involves a fully automatic remote-controlled dough-making device, whose main structure is the same as that of Embodiment 1, but the difference is:

[0082] A stirring shaft A1 is installed inside the flour hopper A, and stirring blades A2 are installed on the stirring shaft A1 for stirring the flour inside the flour hopper A. The stirring shaft A1 is a hollow cylindrical structure with an open top. The upper end of the stirring shaft A1 is connected to the cover plate A4 of the flour hopper A via a bearing. The cover plate A4 is detachably installed on the top of the flour hopper A. The stirring shaft A1 is driven to rotate by a drive mechanism. A rigid spring A3 is fixed to the bottom inner side of the stirring shaft A1. The top of the rigid spring A3 is fixed to a moving block A5. The outer side of the moving block A5 is in contact with the inner wall of the stirring shaft A1. An opening A6 is provided on the stirring shaft A1. The moving block A5 is attached to the rigid spring. Supported by A3, opening A6 can be completely sealed. A movable tube A7 is fitted inside the stirring shaft A1. The movable tube A7 is open at the top and hollow inside. An opening A8, which mates with opening A6, is located on the side of the movable tube A7. Pressing the movable tube A7 downwards presses the moving block A5 down until opening A8 on the movable tube A7 overlaps (partially or completely) with opening A6 on the stirring shaft A1. Flour in the flour bin A can then enter the movable tube A7 through openings A6 and A8. Lifting the movable tube A7 upwards allows for sampling of the flour inside the flour bin A, enabling rapid inspection. When the movable tube A7 is lifted upwards, the moving block A5, under the action of the rigid spring A3, returns to its original position, sealing opening A6 again and preventing flour from entering the stirring shaft A1.

[0083] To further ensure that opening A6 and opening A8 overlap, a fixed plate A9 is provided at the top of the stirring shaft A1, and a positioning plate A10 is provided at the upper end of the movable tube A7. A guide rod A11 is provided between the movable tube A7 and the positioning plate A10. Specifically, the lower end of the guide rod A11 is fixed to the fixed plate A9, and the upper end passes through the positioning plate A10. The positioning plate A10 and the movable tube A7 move up and down along the guide rod A11. When the positioning plate A10 moves downward to fit against the fixed plate A9, opening A6 and opening A8 completely overlap.

[0084] The driving mechanism includes a stirring motor A12 mounted on the top of the flour hopper 1. A drive wheel A13 is installed at the output end of the stirring motor A12. The drive wheel A13 meshes with a driven wheel A14 fixed to the stirring shaft A1. The stirring motor A12 drives the drive wheel A13 to rotate, thereby causing the driven wheel A14 and the stirring shaft A1 to rotate, thus stirring the flour in the flour hopper A and preventing the flour from compacting. Additionally, when sampling is not required, the movable tube A7 can be removed from the stirring shaft A1 to seal the top of the stirring shaft A1.
