[0023] A preferred embodiment of the present invention will be described below in conjunction with the accompanying drawings to clearly and completely describe the technical solution in a preferred embodiment of the present invention.

[0024] See also Figure 1 The present invention comprises a main frame, on which a flat cutting and layering device 2, a dicing device 3 and a top block swaying device 5 are sequentially arranged along the transmission direction of the tofu embryo, and also comprises a white embryo conveying line 1, a cutting knife conveying line 7 and a freezing box conveying line 4; the white embryo conveying line 1 is used to convey the tofu embryo to the flat cutting and layering device 2, and then convey the tofu embryo after flat cutting and layering to the dicing device 3; the cutting knife conveying line 7 is used to drive the dicing device 3 to move to the top block swaying device 5; the freezing box conveying line 4 is used to convey the freezing box to the top block swaying device 5.

[0025] The main working process of the present invention is as follows: first, the pressed tofu is conveyed to the flat cutting and layering device 2 by the white embryo conveying line 1, the flat cutting and layering device 2 cuts the tofu into two layers from the middle of the height of the tofu, and then the layered tofu is conveyed to the dicing device 3 by the white embryo conveying line 1, the dicing device 3 cuts the tofu into designed specifications and sizes, after the dicing device 3 completes dicing of the tofu, the tofu is conveyed to the top block swaying embryo device 5 by the cutting knife conveying line 7, at this time, the freezer conveying line 4 has conveyed the freezer to the top block swaying embryo position, after the cutting knife conveying line 7 conveys the tofu to the top block swaying embryo position, the freezer lifting mechanism lifts the freezer to the adjusted height, and the dicing and swaying embryo device 5 starts to swing the embryo.

[0026] See also Figure 2 and Figure 3The flat cutting layering device 2 includes a mounting plate 27 and a lifting cylinder 23 for driving the mounting plate 27 to move up and down; clamping mechanisms 25 are arranged on both sides of the mounting plate 27, and the clamping mechanisms 25 are driven by the clamping cylinder 24. A rear limit mechanism 211 is arranged at the rear end of the mounting plate 27, and the rear limit mechanism 211 is driven by the rear limit cylinder 212. A rodless cylinder 28 is arranged at the front end of the mounting plate 27, and a tool holder 26 is connected to the rodless cylinder 28. The rodless cylinder 28 can drive the tool holder 26 to move horizontally, and a flat cutting knife 210 is horizontally installed on the tool holder 26.

[0027] In this embodiment, a lower pressing plate 29 is disposed at the bottom of the knife holder 26 , and the height of the lower pressing plate 29 is higher than the flat cutting knife 210 .

[0028] In this embodiment, the flat cutting and layering device 2 also includes a group of guide sleeves 21 symmetrically arranged on both sides of the lifting cylinder 23. The guide sleeves 21 are fixedly connected to the lifting cylinder 23. A guide column 22 is installed in the guide sleeve 21. The lower end of the guide column 22 is fixedly connected to the mounting plate 27. The guide column 22 can slide up and down in the guide sleeve 21.

[0029] The action flow of the above-mentioned flat cutting and stratifying device 2 is as follows: the tofu embryo is transported to the bottom of the flat cutting and stratifying device 2, and the lifting cylinder 23 drives the flat cutting and stratifying device to descend. After it descends into place, the clamping mechanisms 25 on both sides are actuated to clamp, and the rear limiting mechanism 211 is clamped to frame and fix the tofu embryo inside. At the same time, the lower pressing plate 29 presses the tofu embryo from top to bottom. At this time, the rodless cylinder 28 is actuated to drive the flat cutting knife 210 to cut horizontally, and the tofu embryo is cut into two layers from the middle, and after the stratification is completed, the clamping mechanism 25 and the rear limiting mechanism 211 are opened, and the flat cutting and stratifying device rises.

[0030] See also Figure 4-Figure 6 The cutting device 3 includes a slider 31 that can slide along the cutter conveyor line 7, and a square frame cutter 33 and a grid cutter 35 are fixedly connected to the slider 31. The grid cutter 35 can be placed in the outer frame cutter 33. It also includes an outer frame cutter lifting cylinder 32 that drives the outer frame cutter 33 to move up and down, and a grid cutter lifting cylinder 34 that drives the grid cutter 35 to move up and down.

[0031] In this embodiment, a slide rail is provided on the cutter conveyor line 7, and the slider 31 is installed on the slide rail and driven to slide by a synchronous belt.

[0032] The action flow of the above-mentioned slicing device 3 is as follows: the tofu embryo is transported to the bottom of the slicing device 3, the outer frame cutter 33 descends, first cutting around to frame the tofu embryo, then the grid cutter lifting cylinder 34 descends, pushing the grid cutter 35 downward until the slicing is completed.

[0033] See also Figure 7The top block swinging device 5 includes a top block mounting seat 52, and a plurality of top blocks 51 corresponding to the grid cutter 35 are evenly arranged at the bottom of the top block mounting seat 52; a fixing plate 55 is arranged above the top block mounting seat 52, and a No. 1 top block swinging cylinder 56 is installed on the fixing plate 55, and the lower end of the piston rod of the No. 1 top block swinging cylinder 56 is connected to the No. 2 top block swinging cylinder 54, and the piston rod of the No. 2 top block swinging cylinder 54 is connected to the top block mounting seat 52.

[0034] In this embodiment, a group of rotating seats 58 are arranged on one side of the fixed plate 55 of the top block swinging embryo device 5, and the rotating seat 58 is fixedly arranged on the main frame. A rotating shaft 59 is installed on the rotating seat 58, and a handle 53 is arranged on the other side of the fixed plate 55; it also includes a flip assisting gas spring 57 that drives the top block swinging embryo device 5 to rotate along the rotating shaft 59.

[0035] Since a certain distance must be maintained between the tofu blocks when the tofu embryos are arranged, the push block 51 is arranged at intervals compared to the grid of the grid cutter 35, so that each time the push block 51 moves, only one-half of the tofu block is pushed out at intervals.

[0036] The action flow of the above-mentioned top block embryo swinging device 5 is as follows: the cutter conveyor line 7 drives the outer frame cutter 33 and the grid cutter 35 as well as the cut tofu embryo to move to the bottom of the top block embryo swinging device 5 through the slider 31. At this time, the freezer conveyor line 4 has transported the freezer to the right place. First, the No. 1 top block embryo swinging cylinder 56 is actuated, and the top block 51 descends to push the first layer of tofu blocks in the grid of the grid cutter 35 onto the freezer to complete the first embryo swinging. Then the top block 51 is retracted upward, and at the same time, the cutter conveyor line 7 drives the outer frame cutter 33 and the grid cutter 35 to move a specified distance to the next freezer. The top block 51 is actuated again to perform the second embryo swinging, thus completing the embryo swinging work of one layer. When the first layer of embryo swings, only the No. 1 cylinder works, and when the second layer is worked, the No. 1 and No. 2 cylinders work at the same time. Because the tofu is divided into two layers, each layer is pushed twice, one box is swung at a time, and four boxes are swung for each plate of tofu. The working principle of the second layer embryo swinging is the same as the first time.

[0037] In this embodiment, a freezer box lifting mechanism is provided below the top block embryo swinging device 5, and the freezer box lifting mechanism can lift the freezer box to an adjusted height.

[0038] In this embodiment, a cutter cleaning station 6 is provided in connection with the cutter conveyor line 7. After the tofu embryos are arranged, the tofu cutter is conveyed to the cutter cleaning station 6 for cleaning.

[0039] See also Figure 8In this embodiment, the tofu embryo conveyor line 1 includes a conveyor line frame 11, a plurality of shift forks 13 are arranged at equal intervals on the top of the conveyor line frame 11, and a push cylinder 12 for driving the shift forks 13 to move. The push cylinder 12 reciprocates to push the shift forks 13 to convey the tofu embryo to the processing station.
