Description

Technical Field

[0001] This utility model relates to the technical field of soybean grinding, and in particular to a soybean grinding and discharging device for tofu processing. Background Technology

[0002] Tofu processing is a long-established and technologically mature industry that involves multiple steps and techniques.

[0003] In existing soybean grinding and discharging devices used for tofu processing, such as the soybean flour production grinding machine disclosed in utility model patent application number 202323360638.X, the utility model uses a second motor to drive a rotating shaft fixedly connected to it to rotate. The rotation of the rotating shaft drives the gears on it to rotate, and the three gears mesh with each other and rotate, which in turn drives the three rotating shafts to rotate. The rotation of the three rotating shafts drives the three grinding rollers to rotate with each other to crush the broken soybean pulp, thereby realizing the production of soybean flour.

[0004] However, during the soybean milling process, soybeans that are not fully ground will be discharged along with the finished product, resulting in inconsistent soybean flour quality and poor pulp yield. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a soybean grinding and discharging device for tofu processing, which, by setting a return mechanism and an extension mechanism, allows insufficiently ground soybean powder to be backfilled and reprocessed during the soybean grinding process, thereby improving the grinding quality and preventing dust.

[0006] This utility model discloses a soybean grinding and discharging device for tofu processing, which includes a guiding mechanism; it also includes a filtering mechanism, a driving mechanism, a return mechanism, and an extension mechanism. The filtering mechanism is installed inside the guiding mechanism, the driving mechanism is installed on the guiding mechanism, the return mechanism is installed at the right end of the guiding mechanism, and the extension mechanism is installed at the lower end of the guiding mechanism.

[0007] The feeding mechanism guides the soybean powder, the filtering mechanism screens it, the driving mechanism drives the process, the return mechanism returns the powder, and the extension mechanism extends the powder. The feeding mechanism guides the soybean powder, the driving mechanism drives the filtering mechanism to vibrate and screen the soybean powder, and the return mechanism returns the incompletely ground soybean powder for re-grinding. The extension mechanism adjusts the falling space of the soybean powder to prevent it from being too light and scattering in the wind. Thus, during the soybean grinding process, insufficiently ground soybean powder can be returned for re-processing, improving the grinding quality and preventing dust.

[0008] Preferably, the material guiding mechanism includes a discharge channel, a connecting frame, and four sets of screws. The connecting frame is installed on the discharge channel by the four sets of screws. The connecting frame is adapted to the discharge port of the grinder. The round port is connected by the connecting frame, and the square port is connected by the discharge channel and screws. The discharge channel guides the soybean powder.

[0009] Preferably, the filtration mechanism includes a slide, multiple sets of springs, and a filter screen. The slide is supported by multiple sets of springs and installed in the discharge channel, and the filter screen is installed on the slide. The springs support the slide to facilitate vibration, and the filter screen screens the soybean powder.

[0010] Preferably, the drive mechanism includes multiple sets of rubber pads, a crankshaft, and a motor. The multiple sets of rubber pads are installed inside the discharge channel, the crankshaft is rotatably mounted on the discharge channel, and the input end of the crankshaft extends to the left side of the discharge channel. The crankshaft is rotatably connected to the slide rail. The motor is installed at the left end of the discharge channel, and the output end of the motor is connected to the input end of the crankshaft. By turning on the motor, the crankshaft is driven to rotate. While the crankshaft is rotating, it drives the slide rail to vibrate, which in turn cooperates with the filter screen to screen the soybean powder. The rubber pads protect the discharge channel and the slide rail.

[0011] Preferably, the return material mechanism includes an auger, a spiral blade shaft, and a second motor. The auger is installed at the right end of the discharge channel, the spiral blade shaft is rotatably installed inside the auger, and the input end of the spiral blade shaft extends to the upper side of the auger. The second motor is installed at the upper end of the auger, and the output end of the second motor is connected to the input end of the spiral blade shaft. By turning on the second motor, the spiral blade shaft is driven to rotate. While the spiral blade shaft is rotating, the incompletely ground soybean powder is transported upwards for backfilling and reprocessing.

[0012] Preferably, the extension mechanism includes an extension frame, four sets of lead screws, and four sets of nuts. The extension frame is slidably mounted on the discharge channel, and the four sets of lead screws are mounted at the lower end of the discharge channel. Each set of lead screws is fitted with a nut to fix the extension frame. The position of the extension frame can be changed by rotating the nut to engage with the lead screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the soybean powder is guided by the feeding mechanism, the filtering mechanism is driven by the opening of the driving mechanism to vibrate and screen the soybean powder, and the soybean powder is re-filled and re-ground by the opening of the return mechanism. The soybean powder falling space is changed by adjusting the elongation mechanism to prevent the soybean powder from being too light and being scattered by the wind. Thus, during the soybean grinding process, the insufficiently ground soybean powder can be re-filled and reprocessed, improving the grinding quality and preventing dust. Attached Figure Description

[0026] The drive mechanism 3 includes multiple sets of rubber pads 31, a crankshaft 32, and a motor 33. The multiple sets of rubber pads 31 are installed in the discharge channel 11. The crankshaft 32 is rotatably installed on the discharge channel 11, and the input end of the crankshaft 32 extends to the left side of the discharge channel 11. The crankshaft 32 is rotatably connected to the slide rail 21. The motor 33 is installed at the left end of the discharge channel 11, and the output end of the motor 33 is connected to the input end of the crankshaft 32.

[0027] The return mechanism 4 includes an auger 41, a spiral blade shaft 42, and a second motor 43. The auger 41 is installed at the right end of the discharge channel 11. The spiral blade shaft 42 is rotatably installed inside the auger 41, and the input end of the spiral blade shaft 42 extends to the upper side of the auger 41.

A rubber pad 31 protects the discharge channel 11 and the slide 21. Simultaneously, the spiral blade 42 rotates when the motor 43 is turned on, transporting incompletely ground soybean powder upwards for backfilling and reprocessing. The position of the extension frame 51 is changed by rotating the nut 53 in threaded engagement with the lead screw 52 to prevent the soybean powder from being too light and scattered by the wind.
