[0011] The manufacturing method of the above-mentioned household tofu machine with automated production process is as follows: Put soybeans into the crushing and pulping device and add water. After grinding into raw soy milk by the crushing and pulping device, the raw soy milk is discharged into the soy milk boiling and brain discharging device by the slurry discharging device. Then, after boiling the raw soy milk into cooked soy milk by the soy milk boiling and brain discharging device, the brine adding device is used to add brine to generate tofu brain. Then, the tofu brain is discharged into the tofu forming frame. When the tofu forming frame is full of tofu brain, the winch-type tofu forming device is used to form the tofu and the gauze collecting device is used to collect the gauze, so as to automatically manufacture the tofu.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. In the present invention, soybeans are put into a crushing and pulping device and water is added. After being ground into raw soy milk by the crushing and pulping device, the raw soy milk is discharged into a soymilk boiling and curdling device by a slurry discharging device. Then, the raw soy milk is boiled into cooked soy milk by the soymilk boiling and curdling device, and then curdling is carried out by a curdling device to generate bean curd. The bean curd is then discharged into a bean curd forming frame. When the bean curd forming frame is filled with bean curd, a winch-type bean curd forming device is used to form the bean curd and a gauze collecting device is used to collect the gauze. Thus, the present invention can automatically produce bean curd, having the advantages of simple use and convenient production. At the same time, the present invention has a high degree of integration, small floor area, small volume, and ingenious structure. In addition, in the crushing and pulping device of the present invention, a fan and crushing blades are driven by the same crushing motor, achieving simplification of the structure and enabling heat dissipation of the fan while crushing. The slurry discharging device and the curdling device of the present invention both adopt a gear rotation method to realize the opening and closing of the slurry discharging diversion holes and the curdling diversion holes, which is simple and convenient.

[0014] 2. In the present invention, by setting a winch-type bean curd forming device, the rotation of a rocker outside an electromagnetic clutch drives the rotation of a sleeve, and then a pressing rod in the sleeve drives the rotation of a pressing plate, thereby opening the opening of a curd discharging channel, enabling the bean curd in the soymilk boiling and curdling device to be discharged into the bean curd forming frame. When the bean curd forming frame is filled with bean curd, the rocker rotates back to make the pressing plate return to its original position. Then, the electromagnetic clutch is powered off to separate the power of the pressing plate from the roller and they no longer rotate synchronously. Two symmetric rollers are used to suspend weights, causing the weights to drop. Since the pressing plate is connected to the sleeve and the pressing rod in a sleeved manner, when the weights press the pressing plate to descend, the weights will press the limiting spring balls, enabling the gauze pressing plate to move downward to realize the pressing of the bean curd. After pressing is completed, the weights rise under the action of the sleeve, and at the same time, a short rope is used to drive the pressing plate to rise, forming a return effect.

[0015] 3. In the present invention, by setting a gauze collecting device to be linked with the winch-type bean curd forming device, when the winch-type bean curd forming device is started, it drives the pressing plate to press downward. As the pressing plate presses downward and touches the spring ball on the downward pressing track, the downward pressing track and the pressing plate run synchronously. The downward pressing track touches the turning plate, driving the turning plate to rotate, and the torsion spring fixed in the middle of the turning plate is compressed. When the clip touches the second fixed frame, the clip is pressed and opened under the action of the second fixed frame, causing the gauze to fall. At this time, the spring ball on the downward pressing track is also squeezed by the turned clip, causing the spring connected to the spring ball to be compressed and the spring ball to retract into the track, resulting in the downward pressing track no longer being subjected to the downward pressure of the gauze pressing plate. Thus, under the restoring action of the torsion spring, the gauze collecting device returns to its initial state. BRIEF DESCRIPTION OF THE DRAWINGS

A gear is fixed on the other end of the shaft of the drum 809 through a flange. Clutch support seats 802 are respectively provided on both sides of the rolling bearing seat 810. An electromagnetic clutch 801 coaxial with the drum is provided on the clutch support seat 802. A rocker 806 is nested and connected to the outer end of the electromagnetic clutch 801. A connecting rod 813 is provided between the rockers 806 on the same side. A sleeve 814 is provided in the middle of the connecting rod 813. A pressing rod 815 is provided inside the sleeve 814.

The upper end surface of the pressing frame 816 is connected to the weight 811 through a short rope. A limiting spring ball 817 is provided between the upper end of the sleeve 814 and the pressing rod 815. In the present invention, by setting the winch-type tofu forming device, the rotation of the rocker outside the electromagnetic clutch drives the rotation of the sleeve, and then the pressing rod in the sleeve drives the rotation of the pressing plate, so as to open the opening of the brain discharging channel, enabling the tofu brain in the soymilk boiling and brain discharging device to be discharged into the tofu forming frame. When the tofu forming frame is filled with tofu brain, the rocker rotates back to make the pressing plate return to its position. Then, the electromagnetic clutch is powered off to separate the power of the pressing plate from the drum and they no longer rotate synchronously. Then, two symmetric drums are used to suspend the weight so that the weight descends. Since the pressing plate is connected to the sleeve and the pressing rod in a sleeved manner, when the weight presses the pressing plate to descend, the weight will press the limiting spring ball, enabling the gauze pressing plate to move downward to realize the pressing of the tofu. After the pressing is completed, the weight rises under the action of the sleeve, and at the same time, the short rope is used to drive the pressing plate to rise, forming a returning effect.

[0039] As Figures 15 - 16As shown in the figure, the gauze collecting device 9 includes a gauze collecting frame 901 fixed in the tofu forming frame 3 through a card slot. A plurality of second fixed frames 903 are provided on the gauze collecting frame 901. A pressing track 909 is installed on the inner track of the second fixed frame 903. A spring is fixed inside the horizontal end of the pressing track 909, and a slider 910 is installed on the spring. A spring ball 911 is fixed on the outer end of the slider 910. A turning shaft 905 is fixed in the hole at the lower part of the second fixed frame 903. A turning plate 904 is fixed to the turning shaft 905 through a torsion spring 906. One end of the turning plate 904 is located below the vertical end of the pressing track 909. One end of the torsion spring 906 is fixed to the short plate end of the turning plate 904, and the other end is fixed to the second fixed frame 903. A clip rotating shaft 907 is installed on the long plate end of the turning plate 904. A clip 908 is fixed to the clip rotating shaft 907 through a torsion spring. The clip 908 is used to clamp the gauze. In the present invention, by setting the gauze collecting device to be linked with the winch-type tofu forming device, when the winch-type tofu forming device is started, the pressing plate is driven to press down. As the pressing plate presses down and touches the spring ball on the pressing track, the pressing track and the pressing plate run synchronously. When the pressing track touches the turning plate, the turning plate is driven to rotate, and the torsion spring fixed in the middle of the turning plate is compressed. When the clip touches the second fixed frame, the clip is pressed and opened under the action of the second fixed frame, so that the gauze drops. At this time, the spring ball on the pressing track is also squeezed by the turned clip, so that the spring connected to the spring ball is compressed, and the spring ball retracts into the track, resulting in the pressing track no longer being subjected to the downward pressure of the gauze pressing plate.
