[0014] Through the above technical solution, in the tofu cutting and packaging machine provided in this disclosure, since the large-plate tofu conveying mechanism, the strip cutting mechanism, the block cutting mechanism, the second shelf, and the first and second packaging positions are all located in a water tank, the processes of the large-plate tofu being conveyed by the large-plate tofu conveying mechanism to the cutting position, the large-plate tofu being pushed by the large-plate tofu conveying mechanism to the strip cutting mechanism, the strip cutting process of the strip cutting mechanism, the process of the tofu strips being pushed from the second shelf to the block cutting mechanism by the third direct push component, the block cutting process of the block cutting mechanism, and the process of being directly pushed into the box by the first and second direct push components can all be carried out in water. Under the buoyancy and lubrication of the water, even soft tofu with a high water content is not easily damaged or broken. During the process of the third direct push component pushing the tofu strips from the second shelf to the first shelf along the second horizontal direction, the tofu strips can be cut into tofu blocks by the block cutting blades on the first shelf, and the block cutting process and the process of the tofu blocks entering the first and second working positions are carried out simultaneously, which can shorten the working time required for the tofu to be directly pushed into the box and improve production efficiency. The packaging box conveying mechanism can convey the first and second packaging boxes to the first and second boxing positions, respectively. When the first packaging box reaches the first boxing position and the second packaging box reaches the second boxing position, the first and second packaging boxes can be arranged back-to-back along the second horizontal direction and can be arranged alternately along the first direction. As the first and second push components push the tofu blocks forward along the second horizontal direction from the first and second workstations, respectively, adjacent tofu blocks can be separated from each other in a staggered manner along the second horizontal direction. Therefore, the tofu's direct-push boxing process can always proceed forward along the second horizontal direction without needing to separate multiple tofu blocks along the first direction. This greatly reduces the possibility of tofu blocks breaking during boxing and facilitates capacity expansion. Furthermore, since both tofu cutting and boxing are done by machine, product quality control is stable, and the efficiency of tofu cutting and boxing is greatly improved.

Furthermore, when the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0041] According to a specific embodiment of this disclosure, a tofu cutting and packaging machine is provided, see reference. Figures 1 to 11 As shown, the tofu cutting and packaging machine may include a water tank 9, a packaging box conveying mechanism 1, a large tofu conveying mechanism 6, a strip cutting mechanism 7, a second shelf 4, a large tofu pushing mechanism 8, a cutting mechanism 3, and a direct push box feeding mechanism 2.

[0042] Among them, reference Figure 2 and Figure 3 As shown, the water tank 9 is provided with a plurality of first boxing positions 101a for placing the first packaging box 101 and a plurality of second boxing positions 102a for placing the second packaging box 102. The plurality of first boxing positions 101a are spaced apart along the first direction, and the plurality of second boxing positions 102a are spaced apart along the first direction. The first boxing positions 101a and the second boxing positions 102a are arranged alternately along the first direction. The first boxing positions 101a are located in front of the second boxing positions 102a along a second horizontal direction perpendicular to the first direction.

[0043] The packaging box conveying mechanism 1 may include a first conveying channel 11 and a second conveying channel 12 extending parallel to and synchronously moving along a first direction. The first conveying channel 11 and the second conveying channel 12 may be arranged front-to-back along a second horizontal direction. Multiple first packaging boxes 101 may be spaced apart along the first direction in the first conveying channel 11, and multiple second packaging boxes 102 may be spaced apart along the first direction in the second conveying channel 12. The multiple first packaging boxes 101 and multiple second packaging boxes 102 are arranged alternately along the first direction. (Reference) Figure 3 As shown, the packaging box conveying mechanism 1 can convey the first packaging box 101 and the second packaging box 102 downstream along the first direction to the first boxing position 101a and the second boxing position 102a respectively, so that the boxing process of tofu blocks can be carried out in water.

[0044] refer to Figure 10As shown, the large tofu conveying mechanism 6 can be housed in the water tank 9 so that the conveying process of the large tofu can be carried out in water. The large tofu conveying mechanism 6 is used to convey the large tofu to the cutting position. The cutting position along the second horizontal direction can be set behind the second boxing position 102a.

[0045] refer to Figure 10 and Figure 11 As shown, the slicing mechanism 7 can be housed in the water tank 9 so that the slicing process of the large tofu can be carried out in water. The slicing mechanism 7 may include a third shelf 70, which can be fitted and disposed on the front side of the position to be sliced ​​along the second horizontal direction. A slicing blade 71 can be provided on the front side of the third shelf 70 along the second horizontal direction, and the slicing blade 71 can slide back and forth along the first direction.

[0046] refer to Figure 1 and Figure 10 As shown, the second shelf 4 can be accommodated in the water tank 9 and can be fitted onto the front side of the third shelf 70 along the second horizontal direction.

[0047] refer to Figure 3 and Figure 10 As shown, the cutting mechanism 3 can be housed in the water tank 9 so that the cutting process of tofu strips can be carried out in water. It includes a first shelf 30 that is attached to the front side of the second shelf 4 along the second horizontal direction. That is, the cutting position, the third shelf 70, the second shelf 4, the first shelf 30, the second boxing position 102a, and the first boxing position 101a are arranged sequentially from back to front in the second horizontal direction (i.e., the direction in which the direct push boxing mechanism 2 pushes the tofu blocks into the box). The first shelf 30 may include a first station 301 that is aligned with a plurality of first boxing positions 101a along the second horizontal direction, and a second station 302 that is aligned with a plurality of second boxing positions 102a along the second horizontal direction. The first station 301 and the second station 302 are arranged alternately along the first direction. The first shelf 30 may also be provided with a cutting blade 31 that extends along the second horizontal direction. Adjacent first stations 301 and second stations 302 can be spaced apart by the cutting blade 31.

[0048] refer to Figure 10 As shown, the large tofu pushing mechanism 8 can push the large tofu forward along the second horizontal direction so that the front and rear parts of the large tofu can be placed on the second shelf 4 and the third shelf 70 respectively. The cutting blade 71 can cut the front and rear parts of the large tofu along the first direction so that the front part of the large tofu is formed into a tofu strip that extends along the first direction and is placed on the second shelf 4.

[0049] refer to Figure 1 as well as Figures 4 to 6As shown, the direct-push boxing mechanism 2 may include a first direct-push component 21, a second direct-push component 22, and a third direct-push component 23. The third direct-push component 23 can push the tofu strips on the second shelf 4 forward into the first station 301 and the second station 302 along the second horizontal direction. During the process of entering the first station 301 and the second station 302, the tofu strips can be cut into multiple tofu blocks by the cutting blade 31, so that each first station 301 and each second station 302 is respectively placed with tofu blocks. The first direct-push component 21 can push the tofu blocks on the first station 301 to the top of the first boxing position 101a along the second horizontal direction, so that the tofu blocks slowly fall into the first packaging box 101 under the buoyancy of the water. The second direct-push component 22 can push the tofu blocks on the second station 302 to the top of the second boxing position 102a along the second horizontal direction, so that the tofu blocks slowly fall into the second packaging box 102 under the buoyancy of the water.

[0050] Through the above technical solution, in the tofu cutting and boxing machine provided in this disclosure, since the large tofu conveying mechanism 6, the strip cutting mechanism 7, the block cutting mechanism 3, the second shelf 4, and the first boxing position 101a and the second boxing position 102a are all in the water tank 9, the process of the large tofu being conveyed by the large tofu conveying mechanism 6 to the position to be cut, the process of the large tofu being pushed by the large tofu conveying mechanism 6 to the strip cutting mechanism 7 by the large tofu pushing mechanism 8, the strip cutting process of the strip cutting mechanism 7, the process of the tofu strips being pushed by the second shelf 4 to the block cutting mechanism 3 by the third direct push component 23, the block cutting process of the block cutting mechanism 3, and the process of being directly pushed into the box by the first direct push component 21 and the second direct push component 22 can all be carried out in water. Under the buoyancy and lubrication of the water, even tender tofu with a high water content is not easy to break or crack. During the process of pushing the tofu strips from the second shelf 4 to the first shelf 30 along the second horizontal direction, the third push assembly 23 can cut the tofu strips into tofu blocks by the cutting blade 31 on the first shelf 30. The cutting process and the process of the tofu blocks entering the first station 301 and the second station 302 are carried out simultaneously, which can shorten the time required for the tofu to be directly pushed into the box and improve production efficiency. The packaging box conveying mechanism 1 can convey the first packaging box 101 and the second packaging box 102 to the first boxing position 101a and the second boxing position 102a respectively. When the first packaging box 101 reaches the first boxing position 101a and the second packaging box 102 reaches the second boxing position 102a, the first packaging box 101 and the second packaging box 102 can be arranged back and forth along the second horizontal direction and can be arranged alternately along the first direction. Then, during the process of the first push component 21 and the second push component 22 pushing the tofu blocks forward along the second horizontal direction from the first station 301 and the second station 302 respectively, adjacent tofu blocks can be separated from each other in a staggered manner along the second horizontal direction. Thus, the process of pushing the tofu into the box can always proceed forward along the second horizontal direction without having to separate multiple tofu blocks from each other along the first direction. This can greatly reduce the possibility of the tofu blocks breaking during the boxing process and facilitate the expansion and improvement of production capacity. In addition, since the cutting and packaging of tofu are done by machine, the quality control of the product is stable, and the efficiency of cutting and packaging tofu is greatly improved.

[0051] refer to Figure 10 As shown, the large tofu conveying mechanism 6 may include a tray conveying channel 61, in which a tofu tray 60 for holding large tofu sheets may be provided. The tray conveying channel 61 can convey the tofu tray 60 to the cutting position, so that the large tofu sheets in the tofu tray 60 reach the cutting position. Specifically, the tray conveying channel 61 may extend along a first direction to convey the large tofu sheets along the first direction.

[0052] refer to Figure 10As shown, the large tofu pushing mechanism 8 may include a push plate 81 and a lead screw motor 82. Specifically, the push plate 81 may have a fourth initial position (see reference) along the second horizontal direction behind the tray conveying channel 61. Figure 10 The position of the push plate 81), and the fourth working position where the front part of the large tofu block is pushed to the second shelf 4 along the second horizontal direction. The lead screw motor 82 may include a lead screw 821 extending along the second horizontal direction and a nut 822 sleeved on the lead screw 821. The push plate 81 may be fixedly connected to the nut 822. When the lead screw 821 rotates, it can cause the nut 822 to move along the lead screw 821, so as to drive the push plate 81 to reciprocate between the fourth initial position and the fourth working position, thereby pushing the large tofu block to be cut forward along the second horizontal direction to the second shelf 4 and the cutting mechanism 7. When the third push assembly 23 pushes the tofu strips on the second shelf 4 forward onto the first shelf 30, the pusher plate 81 can continue to push the large tofu slabs remaining on the third shelf 70 forward, so that their front parts move forward onto the second shelf 4, thereby forming new tofu strips on the second shelf 4 after being divided by the cutting blade 71, until all the large tofu slabs on the third shelf 70 are pushed onto the second shelf 4. After that, the pusher plate 81 can push the large tofu slabs forward again from the tofu tray 60 at the position to be cut.

[0053] refer to Figure 11 As shown, the slicing mechanism 7 may include a second guide rail 72 disposed on the side of the third shelf 70 facing the second boxing position 102a. The second guide rail 72 may extend along a first direction, and the slicing blade 31 may be slidably connected to the second guide rail 72.

[0054] After being cut by the cutting blade 71, although the tofu strips on the second shelf 4 and the large tofu slabs on the third shelf 70 are no longer connected, the cut surfaces of the tofu strips and the large tofu slabs are still attached. In order to separate the tofu strips from the large tofu slabs, the third shelf 70 can be lower than the first shelf 30. The second shelf 4 can be raised and lowered between the third shelf 70 and the first shelf 30. The second shelf 4 can be configured such that when there are tofu strips on the second shelf 4, the second shelf 4 can rise to be flush with the first shelf 30 so that the tofu strips are separated from the rear part of the large tofu slabs, thereby facilitating the third push assembly 23 to push the tofu strips forward from the rear side of the tofu strips. When the third push assembly 23 pushes the tofu strips forward from the second shelf 4 into the first station 301 and the second station 302, the second shelf 4 can fall to be flush with the third shelf 70 to receive the front part of the large tofu slabs. By raising and lowering the second shelf 4, the tofu strips can be separated from the large tofu sheets, while reducing the possibility of the tofu strips and large tofu sheets breaking apart.

The cylinder seat of the fourth lifting drive cylinder 16 may be fixedly connected to the frame 10 of the tofu cutting and packaging machine. The piston rod of the fourth lifting drive cylinder 16 may drive the welding frame 17 to lift and lower, so that when the tofu blocks are pushed above the first packaging position 101a and the second packaging position 102a, the first packaging box 101 and the second packaging box 102 are lifted from the water in the water tank 9, so as to reduce the collision between the tofu blocks and the first packaging box 101 and the second packaging box 102, and further avoid the tofu blocks from breaking and cracking.

[0071] refer to Figure 2 As shown, because the length of one end of the first conveying channel 11 and the second conveying channel 12 used for setting the box placement position is longer than the length of the other end, the welding frame 17 may tilt when it is lifted by the fourth lifting drive cylinder 16. To avoid tilting of the welding frame 17 when it is lifted, refer to...
