[0021] like Figure 1-8 As shown, an auxiliary packaging device for a rice dumpling production line includes: Frame 1, transmission member 2, controller 3, limit frame 4, automatic weighing and feeding assembly. Since the zongzi can have fillings, two groups of automatic weighing and feeding assemblies can be provided. A certain weight of glutinous rice is poured respectively, and the fillings are put at the station between the two groups of automatic weighing and feeding assemblies. The two groups of automatic weighing and feeding assemblies are respectively located on both sides of the filling-putting station. First, a certain weight of glutinous rice is poured by the first group of automatic weighing and feeding assembly, and then the fillings are put at the station between the two groups of automatic weighing and feeding assemblies. Finally, a certain weight of glutinous rice is poured again by the second group of automatic weighing and feeding assembly to form a complete zongzi structure. When the limit frame 4 moves to the weighing station, the weighing cylinder 6 can accurately pour the glutinous rice into the zongzi leaves in the limit frame 4 after being turned over. The transmission member 2 is mounted on the frame 1 and is used to cyclically transmit the limit frame 4. The length of the transmission member 2 in the accompanying drawings is only a schematic diagram. Its transmission length can be increased according to the subsequent bundling and packaging stations. If the processing distance is too long, a tensioning wheel structure can be set at the bottom. However, it should be noted that the wrap angle between the tensioning wheel and the chain 204 needs to be greater than or equal to 120°, and the corresponding slide rail 205 needs to be set according to the distribution of the chain 204. The top of the limiting frame 4 is provided with a rice dumpling placement groove that runs through the whole body, which is used to fix the triangular rice dumpling leaf. The limiting frame 4 is equidistantly distributed. The through-type rice dumpling placement groove of the limiting frame 4 makes the rice dumpling leaf bottom suspend, which is convenient for subsequent artificial or mechanical hand to lift it out; The automatic weighing and feeding assembly includes a mounting frame 5, a weighing cylinder 6, a flipping member 7, a material storage bin 8, a third electric telescopic rod 9 and a sliding support plate 901. When the limit frame 4 moves to the weighing station, the weighing cylinder 6 flips over and unloads the material, and the glutinous rice falls directly into the rice dumplings leaves. The weighing station can be provided with a material in-place sensor. When the limit frame 4 is detected to be in place, the in-place sensor will send a signal to the controller 3, and the controller 3 will control the flipping member 7 to work, thereby realizing automatic dumping and unloading. The storage bin 8 is fixed to the top of the mounting frame 5, and the bottom is connected to the discharge pipe 801. A spiral stirrer is provided in the storage bin 8 to prevent the glutinous rice from clumping. At the same time, the dragon conveying blades provided in the discharge pipe 801 can drive the glutinous rice to rotate and discharge, thereby avoiding blockage and ensuring uniform discharge. The sliding support plate 901 is slidably arranged inside the mounting frame 5 and is driven to rise and fall by the third electric telescopic rod 9; The weighing cylinder 6 is connected to the sliding support plate 901 through a flip member 7, and the flip member 7 can drive the weighing cylinder 6 to dump the material. The flip angle of the weighing cylinder 6 is 90 ° -120 °, and after flipping, its discharge port is aligned with the rice dumpling placement slot of the limiting frame 4; The weighing cylinder 6 is provided with a weighing piston plate 602 and a pressure sensor 603 for real-time detection of the weight of glutinous rice. The controller 3 receives the signal from the pressure sensor 603 and controls the process: 1. The third electric telescopic rod 9 extends → the discharge tube 801 is inserted into the weighing cylinder 6 → discharge begins; 2. Pressure sensor 603 reaches the set value → stop feeding; 3. The transmission member 2 moves the limit frame 4 to the weighing station. The flipping member 7 actuates to dump the glutinous rice. The first electric telescopic rod 601 extends, pushing the weighing piston plate 602 to push the glutinous rice outward. 4. Enter the next cycle after reset. If the weight detected by the pressure sensor 603 exceeds the tolerance, the controller 3 will trigger an alarm signal and simultaneously suspend the movement of the transmission component 2 by controlling the motor 202 so that the staff can check and handle the abnormal situation in time.

[0022] like Figure 3 As shown, the transmission component 2 includes: Support frame 201, motor 202, sprocket 203, chain 204 and slide rail 205; The motor 202 drives the chain 204 to circulate through the sprocket 203; The slide rails 205 are fixed on the support frame 201 and are distributed around the outside of the chain 204; specifically, the slide rails 205 play a bearing and supporting role on the limit frame 4, ensuring that the chain 204 can be transported horizontally.

[0023] like Figure 3 and 4 As shown, a slider 401 is provided at the bottom of the limiting frame 4 , the slider 401 is slidably adapted to the slide rail 205 , and the bottom of the slider 401 is fixedly connected to the chain 204 through a connecting plate 402 .

[0024] like Figure 5 and 6 As shown, the turning member 7 includes: Fixed frame 701, connecting rod 702, second electric telescopic rod 703; The fixing frame 701 is fixed on the sliding support plate 901; The weighing cylinder 6 is hinged to the fixed frame 701 through the connecting rod 702; One end of the second electric telescopic rod 703 is hinged on the fixed frame 701, and the other end is hinged on the side wall of the weighing cylinder 6, which is used to drive the weighing cylinder 6 to flip. Specifically, when the second electric telescopic rod 703 is extended, it pushes the weighing cylinder 6 to rotate a certain angle around the connecting rod 702, and pours the glutinous rice into the rice dumplings leaves of the limit frame 4. Reset process: after flipping, the second electric telescopic rod 703 is retracted, the weighing cylinder 6 returns to its original position, and the third electric telescopic rod 9 is extended to lift the weighing cylinder 6 to its initial height.

[0025] like Figure 6 As shown, the weighing piston plate 602 is slidably connected to the weighing cylinder 6 through the first electric telescopic rod 601, and is used to carry the glutinous rice raw material. The pressure sensor 603 is set on the weighing piston plate 602; specifically, the pressure sensor 603 can weigh the glutinous rice raw material. In order to avoid friction errors, the pressure sensor 603 can be set at the bottom of the weighing piston plate 602, and the weighing piston plate 602 and the pressure sensor 603 are connected through a movable limiting structure.

[0026] like Figure 1-2 As shown, the discharge tube 801 is coaxially arranged with the weighing cylinder 6. When the third electric telescopic rod 9 is extended, the discharge tube 801 is inserted into the inside of the weighing cylinder 6, and when it is retracted, the weighing cylinder 6 is driven to drop synchronously. Specifically, when weighing, the third electric telescopic rod 9 is gradually retracted, driving the weighing cylinder 6 to drop, keeping the discharge tube 801 always inserted into the weighing cylinder 6, avoiding the impact of the falling material height change on the weighing accuracy, and dynamically descending to compensate for the falling material impact. The pressure sensor 603 reading is more stable, and the third electric telescopic rod 9 can be controlled by an encoder.

[0027] like Figure 6 and 7 As shown, a guide groove is provided on the inner side of the mounting frame 5, and protrusions that cooperate with the guide groove are provided on both sides of the sliding support plate 901; specifically, the protrusions of the sliding support plate 901 are slidably adapted to the guide groove of the mounting frame 5 to ensure that the weighing cylinder 6 can be lifted and lowered vertically without shaking.

[0028] like Figure 1-7As shown, the controller 3 is electrically connected to the motor 202, the pressure sensor 603, the first electric telescopic rod 601, the second electric telescopic rod 703, and the third electric telescopic rod 9 to control the weighing, flipping and transmission actions; specifically, the controller 3 controls the actions of the first electric telescopic rod 601, the second electric telescopic rod 703, and the third electric telescopic rod 9 through their respective drive circuits. During the flipping and material pushing process of the weighing cylinder 6, the controller 3 controls the telescopic actions of these electric telescopic rods in sequence according to a preset program: when weighing, the controller 3 first controls the extension of the third electric telescopic rod 9 to drive the weighing cylinder 6 to rotate, and the second electric telescopic rod 703 and the third electric telescopic rod 9 to rotate. The weighing cylinder 6 descends, the discharge tube 801 is inserted into the weighing cylinder 6, and the material begins to be discharged. The weighing cylinder 6 also gradually moves away from the discharge tube 801; when it is necessary to flip the weighing cylinder 6 to dump the glutinous rice, the controller 3 controls the second electric telescopic rod 703 to extend, pushing the weighing cylinder 6 to rotate around the connecting rod 702; when dumping, the controller 3 controls the first electric telescopic rod 601 to extend and push the weighing piston plate 602 to move, thereby pushing the glutinous rice raw material outward. After the dumping is completed, the controller 3 controls the second electric telescopic rod 703 to retract, so that the weighing cylinder 6 returns to its position, and at the same time controls the third electric telescopic rod 9 to extend and lift the weighing cylinder 6 to its initial height.

[0029] Working principle: 1. Transport and Positioning: The transport component 2 on the frame 1 is driven by a motor 202, which drives the sprocket 203 and chain 204 to circulate, driving the limit frame 4 to move along the slide rail 205. The slider 401 at the bottom of the limit frame 4 slides with the slide rail 205 and is fixed to the chain 204 via a connecting plate 402 to ensure stable transport. When the limit frame 4 reaches the weighing station, the material arrival sensor triggers a signal, and the controller 3 starts the automatic weighing and loading process. 2. Glutinous Rice Weighing and Discharging: The automatic weighing and discharging assembly includes a mounting frame 5, a storage silo 8, a weighing drum 6, and a tilting member 7. A spiral agitator within the storage silo 8 prevents glutinous rice from clumping. Dragon blades within the discharge tube 801 evenly transport glutinous rice to the weighing drum 6. During weighing, the third electric telescopic rod 9 extends, allowing the discharge tube 801 to penetrate the weighing drum 6, and the glutinous rice falls onto the weighing piston plate 602. A pressure sensor 603 monitors the weight in real time, and discharging stops when the set value is reached. 3. Layered feeding control: After the first set of weighing cylinders 6 completes weighing, the transmission component 2 sends the limit frame 4 to the filling station to add the filling, and then moves it to the second set of weighing cylinders 6 to add the upper layer of glutinous rice, forming a "bottom layer glutinous rice-filling-upper layer glutinous rice" rice dumpling structure. 4. Flipping, dumping, and resetting: When the limit frame 4 is in place, the second electric telescopic rod 703 of the flipping member 7 extends, pushing the weighing cylinder 6 to rotate 90°-120° around the connecting rod 702, so that the discharge port is aligned with the rice dumping slot; at the same time, the first electric telescopic rod 601 pushes the weighing piston plate 602 to completely push out the glutinous rice. After dumping is completed, the second electric telescopic rod 703 retracts and resets the weighing cylinder 6, and the third electric telescopic rod 9 extends to lift the weighing cylinder 6 to the initial height, preparing for the next cycle. In summary, the device accurately transports the limit frame 4 through the transmission component 2, combines two sets of automatic weighing and feeding components to realize layered feeding, and the controller 3 coordinates the weighing, flipping, pushing and resetting actions to complete efficient and stable automatic packaging of rice dumplings.
