[0002] Kneading the dough is a crucial step in traditional pastry making, requiring flour to be mixed with an appropriate amount of water and stirred evenly. Manually adding flour to the dough is time-consuming and laborious, and the amount added is difficult to control. Therefore, automatic flour adding devices can be used. However, existing automatic flour adding devices have poor metering accuracy, resulting in the addition of too much or too little flour. Utility Model Content
[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and propose to design an automatic flour adding device for a dough mixer, which can accurately measure the amount of flour added.

[0006] Weighing module, fixed on the base frame;
[0007] The weighing silo is connected to the weighing module and has a powder adding port on the top;
[0008] The conveying auger is installed at the bottom of the weighing silo and is used to convey the flour in the weighing silo;
[0009] The reduction motor is connected to the rear end of the conveying auger and is used to drive the conveying auger;
[0010] The limit switch is located at the upper front end of the conveying auger;
[0011] The pneumatic valve is arranged at the lower part of the front end of the conveying auger. A soft connection is provided at the bottom of the pneumatic valve, and a discharge port is provided at the bottom of the soft connection.
[0012] The above technical solution can accurately measure weight through the weighing module and close the pneumatic valve in time to stop discharging, effectively avoiding the problem of adding too much or too little powder.
[0013] Furthermore, a silo top dust collector is provided on the top of the weighing silo, and the silo top dust collector plays a dust removal role during the flour adding process.
[0014] Furthermore, a cleaning port is provided at the bottom end of the weighing silo, which is connected to the conveying auger and is used to discharge flour remaining in the weighing silo and the conveying auger.
[0015] Furthermore, the weighing silo includes an upper cylinder and a lower cone connected in sequence from top to bottom.
[0016] Furthermore, an air hammer is provided on the outer side of the lower cone for hammering the lower cone to make the flour fall smoothly.
[0017] Furthermore, an electric control box is provided on the chassis, and the electric control box is used to control equipment such as a reduction motor, a pneumatic valve, and an air hammer.

[0019] Furthermore, a coupling is installed on the output shaft of the reduction motor, and the other end of the coupling is connected to the rear end of the conveying auger.
[0020] Technical effects of this utility model:
[0021] Compared to existing technologies, the automatic flour-adding device for a dough mixer in this utility model uses a weighing module to weigh the weighing hopper. When a predetermined amount of flour is added, the pneumatic valve is closed to achieve precise metering. After the pneumatic valve is closed, the flour continues to be conveyed forward by the conveying auger until the flour accumulates and contacts the limit switch. The reduction motor is then turned off, stopping the flour conveying. This prevents the conveying auger from being deformed by excessive force and ensures that the flour inside the conveying auger is always full of flour, saving time for the next delivery.

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.
[0026] Example 1:
[0027] like Figure 1As shown, the present embodiment involves an automatic powder adding device for a dough mixer, comprising a base frame 1, a weighing module 2, a weighing silo 3, a powder adding port 4, a conveying auger 5, a cleaning port 6, a reduction motor 7, a coupling 8, a limit switch 9, a pneumatic valve 10, a flexible connection 11, a discharge port 12, a silo top dust collector 13, an air hammer 14 and an electric control box 15.
[0028] The weighing module 2 is fixed on the base frame 1 .
[0029] The weighing silo 3 comprises an upper cylinder 301 and a lower cone 302, connected sequentially from top to bottom. The upper cylinder 301 is connected to the weighing module 2. An air hammer 14 is positioned on the outer side of the lower cone 302, striking it to ensure a smooth drop of flour. The top of the weighing silo 3 is equipped with a powder feeding port 4 and a silo top dust collector 13, located to the side of the powder feeding port 4 and used to remove dust during the flour addition process. A cleaning port 6 is located at the bottom of the weighing silo 3.
[0030] The conveying auger 5 is disposed at the bottom of the weighing silo 3 and is used to convey the flour within the weighing silo 3. Specifically, the conveying auger 5 is disposed horizontally, with the rear end of the conveying auger 5 connected to a coupling 8. The coupling 8 is mounted on the output shaft of a reduction motor 7, and the conveying auger 5 is driven to rotate by the reduction motor 7. A limit switch 9 is disposed at the upper front end of the conveying auger 5, and a pneumatic valve 10 is disposed at the lower front end. A flexible connection 11 is disposed at the bottom of the pneumatic valve 10, and a discharge port 12 is disposed at the bottom of the flexible connection 11. The upper end of the conveying auger 5 near the reduction motor 7 is connected to the interior of the weighing silo 3, and the lower end is connected to the cleaning port 6. The cleaning port 6 is normally closed and is opened when it is necessary to discharge the flour remaining in the weighing silo 3 and the conveying auger 5.
[0031] The electric control box 15 is arranged on the base frame 1 and is used to control equipment such as the reduction motor 7, the pneumatic valve 10, and the air hammer 14.
[0032] When the present invention is in use, flour falls into the interior of the conveying auger 5 through the bottom of the weighing silo 3. The reduction motor 7 drives the conveying auger 5 to rotate through the coupling 8, pushing the flour to the front end of the conveying auger 5. The pneumatic valve 10 opens, and the flour is discharged from the discharge port 12 through the flexible connection 11. The weighing module 2 monitors the weight of the weighing silo 3 in real time. When the weight reaches the set value, the pneumatic valve 10 closes, and the conveying auger 5 continues to operate. When the flour hits the limit switch 9 at the front end of the conveying auger 5, the reduction motor 7 stops.
[0033] The dust collector 13 on the top of the silo of the utility model filters flour to prevent flour from flying when adding flour to the weighing silo 3; the remaining flour inside can be cleaned through the cleaning port 6; after reaching the delivery set value, the pneumatic valve 10 is closed, and the delivery auger 5 stops adding flour to the dough hopper of the dough mixer, ensuring accurate powder metering; the reduction motor 7 is not shut down until the flour contacts the limit switch 9, firstly, to prevent the flour inside the delivery auger 5 from being too full and mechanical failures such as deformation of the auger caused by excessive force, and secondly, to ensure that the flour inside the delivery auger 5 is in a full state, saving time for the next delivery and improving the efficiency of the next powder adding; the air hammer 14 performs regular hammering action to hammer down the flour inside the weighing silo 3, preventing flour from lumping and ensuring that the flour falls smoothly.
[0034] The above-mentioned specific implementation methods are only specific cases of the present utility model. The patent protection scope of the present utility model includes but is not limited to the above-mentioned specific implementation methods. Any appropriate changes or modifications made to them by ordinary technicians in the relevant technical field that comply with the claims of the present utility model shall fall within the patent protection scope of the present utility model.
