DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the utility model will be apparently and completely described in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0023] Please refer to Figures 1-5 The utility model provides a kind of technical scheme: an automatic bean product production line, including the grinding mechanism 1, the boiling pot 2, the forming mechanism 3 and the pre -drying oven 4, the grinding mechanism 1, the boiling pot 2 and the forming mechanism 3 are sequentially connected through main pipeline, and are all provided with solenoid valve on main pipeline, the upper end of grinding mechanism 1 is placed with the feeding mechanism 5, the forming mechanism 3 is provided with the mechanical arm 6 in the directly upper side, is provided with the first conveying frame 7 between the forming mechanism 3 and the mechanical arm 6, one end of first conveying frame 7 is fixedly connected with the second conveying frame 8, and the inner surface of first conveying frame 7 and second conveying frame 8 is all installed with chain 9, and the inside of chain 9 is installed with gear 10, and gear 10 is connected through the pivot with drive device 11, and the upper end of chain 9 is placed with the hanging rod 12.

[0024] The automatic bean product production line each component collaborative operation of line. Feeding mechanism 5 is automatically absorbed by negative pressure device connected with feeding pipe, and inside screw propelling tube sends raw material into grinding mechanism 1 at uniform speed. Grinding mechanism 1 is connected by three grinding machines, and sequentially completes rough grinding, fine grinding, finishing process, and produces fine soybean milk. Soybean milk flows into boiling pot 2 through main pipeline, and temperature sensor in pot feeds back temperature information to central control component 14, when reaching set temperature, central control component 14 controls solenoid valve to open, and soybean milk enters the heating groove of forming mechanism 3 through pulp inlet pipe 13. In heating groove, soybean milk surface moisture evaporates, and protein and other ingredients gather to form bean skin. Mechanical arm 6 is hung on the hanging rod 12 of chain 9 according to preset program and takes down bean skin. When hanging rod 12 is hung full of bean skin, central control component 14 starts drive device 11, and drive gear 10 drives chain 9, and hanging rod 12 and bean skin are sequentially transferred to second conveying frame 8, and finally enter pre -drying oven 4 and are dried by infrared lamp tube.

[0025] When the mechanical arm 6 peels the bean skin, the edge of the bean skin can be located by using a visual recognition system first. The visual positioning is a conventional technology and will not be described again. The end effector of the mechanical arm is lowered to be close to the surface of the bean skin, clamps the bean skin, and then slowly lifts the mechanical arm to completely lift the bean skin and transfer it to the hanging rod 12. The second conveying frame 8 penetrates the inside of the pre-oven 4, and the horizontal height thereof is slightly lower than that of the first conveying frame 7. The hanging rod 12 automatically slides from the first conveying frame 7 to the second conveying frame 8 by using the height difference, realizes non-contact and efficient transfer, reduces manual operation, reduces the risk of product contamination, and improves the overall conveying efficiency.

[0026] The use of two sets of conveying frames can increase the flexibility of the production line layout, and can be reasonably planned according to the workshop space. Different heights are set to facilitate natural transition of materials without adding complex transfer equipment. The hanging rod 12 is a plurality of chains 9 evenly distributed on the upper end of the first conveying frame 7 and the second conveying frame 8, and the upper end of the hanging rod 12 is arc-shaped, and the lower end of the hanging rod 12 is provided with inverted triangular teeth. The arc design of the upper end of the hanging rod 12 can prevent the bean skin from being scratched when hanging the bean skin, ensuring the integrity of the product. The inverted triangular teeth at the lower end of the hanging rod 12 are embedded in the gap of the chain 9, which plays a fixing and limiting role to prevent the hanging rod 12 from deviating during the conveying process of the chain 9, and ensures the stable transportation of the bean skin.

[0027] In the embodiment, as shown in Figure 2 and Figure 3 , the grinding mechanism 1 is connected in series by three grinding machines, and the three grinding machines are used for rough grinding, fine grinding and precision grinding. The three grinding machines in the grinding mechanism 1 are connected in series, the rough grinding machine preliminarily crushes soybeans with a large gap between the grinding discs to reduce the particle size; the fine grinding machine further reduces the gap between the grinding discs to refine the soybean particles; and the precision grinding machine produces uniform and delicate soy milk through a very small gap between the grinding discs. This step-by-step grinding method improves the grinding efficiency and the quality of soy milk. The forming mechanism 3 is provided with a plurality of forming grooves, and each forming groove is provided with a separate feeding pipe 13 connected with the main pipeline. Each forming groove of the forming mechanism 3 is provided with an independent feeding pipe 13 connected with the main pipeline. The central control assembly 14 can automatically control the flow of the feeding pipe 13 according to the feedback information of the liquid level sensor in the forming groove, realize accurate feeding, and ensure the stability of the soy milk liquid level in each forming groove and the consistency of the soy milk forming quality.

[0028] The side of the soy milk boiling pot 2 is provided with a central control assembly 14, which is electrically connected with the electromagnetic valve on the main pipeline, the driving device 11 and the mechanical arm 6. The central control assembly 14 integrates the control of the electromagnetic valve on the main pipeline, the driving device 11 and the mechanical arm 6. The number of times of grabbing by the mechanical arm 6 is recorded in real time, and when the preset value is reached, a signal is immediately sent to the driving device 11 to rotate the driving gear 10 to realize automatic conveying of the hanging rod 12 and improve the automation level of the production line.

[0029] Working principle:

[0030] The feeding mechanism 5 is connected to the feeding pipe, and the feeding pipe realizes automatic feeding through a negative pressure device. The raw materials in the feeding mechanism 5 are uniformly conveyed to the grinding mechanism 1 through the spiral pushing pipe at the bottom of the feeding mechanism 5. The raw materials are ground by the grinding mechanism 1, and the ground pulp is conveyed into the boiling kettle 2 through the main pipe. The boiling kettle 2 is provided with a temperature sensor connected to the central control component 14. When the pulp reaches the set temperature, the central control component 14 opens the corresponding electromagnetic valve to convey the pulp into the heating tank in the forming mechanism 3 through the pulp inlet pipe 13. The soy milk in the heating tank of the forming mechanism 3 is heated, and the water evaporates, and the protein and other components in the soy milk gather on the surface to form a thin film. At this time, the mechanical arm 6 identifies the position of the bean skin according to the preset program, and then uses the clamping device at the bottom to accurately fit the bean skin and apply appropriate clamping force to lift the formed bean skin. When the lifting frequency of the mechanical arm 6 reaches the set frequency, the bean skin on the upper end of the single hanging rod 12 is full. The central control component 14 starts the driving device 11 to drive the gear 10 to rotate, and drives the chain 9 in the first conveying frame 7 to rotate, and the hanging rod 12 and the bean skin on the upper end of the hanging rod 12 are conveyed to the upper end of the chain 9 in the second conveying frame 8. The first conveying frame 7 and the second conveying frame 8 cooperate to increase the conveying distance and efficiency, and the different heights facilitate the transfer of materials. When the hanging rod 12 in the first conveying frame 7 moves to the connection position of the second conveying frame 8, it directly slides onto the upper end of the second conveying frame 8 and is conveyed to the pre-drying oven 4 by the second conveying frame 8. The hanging rod 12 enters the pre-drying oven 4 with the chain 9 of the second conveying frame 8, and the infrared lamp in the pre-drying oven 4 heats the bean skin to complete the preliminary drying and prepare for subsequent processing.

[0031] Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.
