Description

Technical Field

[0001] This invention relates to the field of automatic cutting and packaging, specifically to an automatic tofu cutting and packaging machine in water. Background Technology

[0002] Tofu is a delicious and nutritious food that people often eat in their daily lives. In automated production processes, the produced tofu is often cut into blocks, packaged, and sealed for easy transportation and sale.

[0003] Currently, due to the fragility of tofu, there are no integrated cutting and packaging machines on the market, resulting in low processing efficiency. Slight carelessness during packaging can easily lead to tofu breakage, affecting the integrity and appearance of the tofu inside the box. For example, a tofu automatic packaging machine disclosed in patent number CN107161369A involves tofu moving from a tofu conveyor line to a tofu acceleration mechanism. When the portion of the tofu that has reached the acceleration mechanism reaches approximately two-thirds of its total length, the acceleration mechanism applies acceleration to the tofu, separating it from other tofu on the conveyor line. A tofu pulling mechanism pulls the tofu onto a tofu tray, and a tofu tray rotation mechanism rotates the tray and the tofu on it before pulling the tray out, allowing the tofu to fall into the tofu box. While this structure solves the problem of tofu breakage during packaging, the structure and process are overly cumbersome.

[0038] A preferred embodiment of the present invention will now be described in conjunction with the accompanying drawings, providing a clear and complete description of the technical solution in this preferred embodiment.

[0039] like Figures 1 to 2As shown, an automatic tofu cutting and packaging machine in water includes: a water tank assembly 100, characterized in that the water tank assembly 100 includes a waiting area 1, a pushing area 2, and a cutting area 3 connected in sequence; the pushing area 2 is provided with a pushing mechanism; the cutting area 3 is provided with a cutting frame 101; one side of the cutting frame 101 is provided with a horizontal cutting component 32; the other side of the cutting frame 101 is provided with a pressing and balancing component 33 and a plurality of vertically arranged cutters 34; the pressing and balancing component 33 and the plurality of vertically arranged cutters 34 are connected to the cutting frame 101 through a rotary pressing and cutting mechanism; the cutting area 3 is also provided with a box-dropping fixing frame 102 fixedly connected to the water tank assembly 100; below the box-dropping fixing frame 102 are a long rotating shaft, a tofu tray assembly 4, and a fork assembly 5; the fork assembly 5 includes a U-shaped frame, the U-shaped frame being provided with... Two comb-shaped plates 51 are arranged at intervals, with the gap between them used to fix the edge of the tofu box so that the tofu box can hold the tofu on the tofu tray assembly 4 in place. The tofu tray assembly 4 and the two comb-shaped plates 51 are connected to the box-dropping fixing frame 102 via a rotating lifting mechanism. A box-dropping mechanism 1021 is provided above the box-dropping fixing frame 102, and a box-receiving component 8 corresponding to the fork assembly 5 is provided below the box-dropping mechanism 1021. The box-receiving component 8 is rotatably connected to the water tank assembly 100. The box-receiving component 8 is provided with comb teeth 82 corresponding to the comb-shaped plates 51 of the fork assembly 5 so that the edge of the tofu box can smoothly enter the gap between the two comb-shaped plates 51. A conveyor 103 is provided on the water tank assembly 100 outside the cutting area 3. The conveyor 103 is provided with a box-scraping mechanism 9.

[0040] Through the above design, the present invention divides the water tank assembly 100 into a waiting area 1, a pushing area 2, and a cutting area 3 connected in sequence. The placement robot first places the whole board of tofu in the waiting area 1, and then the placement robot pushes the whole board of tofu into the pushing mechanism in the pushing area 2. The pushing mechanism pushes the whole board of tofu to the horizontal cutting component 32, the pressing component 33, and the vertical cutting blade 34, and performs strip cutting and block cutting in sequence.

[0041] Strip cutting: The pushing mechanism pushes the whole board of tofu to the horizontal cutting component 32, and the horizontal cutting blade 323 cuts the front ends of the two boards of tofu into strips according to the designed width, and the strip cutting is completed.

[0042] Block cutting: The pushing mechanism continues to push the whole plate of tofu to prepare for the second strip cutting. During the second strip cutting, the first strip of tofu has been pushed onto the tofu tray assembly 4. The tofu tray assembly 4 is lifted by the rotating lifting mechanism to the pressing assembly 33 and the vertical cutting blade 34. Then the pressing assembly 33 rotates downward to press down on the strip of tofu. Multiple vertical cutting blades 34, which are set at equal intervals, rotate downward to cut the strip of tofu into blocks.

[0043] Then, the receiving box 8 rotates towards the shift fork assembly 5, conveying the inverted tofu box that has fallen from the dropping mechanism 1021 to the shift fork assembly 5, which is rotating towards the receiving box 8. During conveying, the comb-shaped teeth 82 of the receiving box 8 correspond to the comb-shaped plates 51 of the shift fork assembly 5, so that the edge of the inverted tofu box enters the gap between the two comb-shaped plates 51. The shift fork assembly 5 with the inverted tofu box then rotates towards the tofu tray assembly 4, so that the inverted tofu box completely holds the tofu on the tofu tray assembly 4.

[0044] Then, the tofu tray assembly 4, the block of tofu that is held in place, and the fork assembly 5 are rotated 180 degrees upward around the long shaft 6 under the action of the rotating lifting mechanism. After the rotation is completed, the tofu box with the opening facing upward, together with the tofu block inside, is placed on the scraping mechanism 9. The scraping mechanism 9 transports both to the conveyor 103, and the conveyor 103 transports both to the next processing point. The present invention has a simplified structure, greatly improves efficiency, and achieves zero contact and zero pollution in the entire cutting and loading process.

[0045] like Figure 2 As shown, the transverse cutting assembly 32 of the present invention includes a transverse motion module 322 and a transverse cutter 323 fixed on the moving plate of the transverse motion module 322.

[0046] The present invention achieves the cutting of a whole plate into strips through the above design.

[0047] like Figures 3 to 4 As shown, the pressing and balancing assembly 33 of the present invention includes a pressing and balancing frame 331, on which a plurality of pressing and balancing rods 332 are connected at equal intervals, and the pressing and balancing frame 331 is connected to the pressing and balancing rotating support arm 333.

[0048] The rotary cutting mechanism includes a fixed shaft 35, vertical cutting cylinders 36 located on both sides of the fixed shaft 35, and pressure-release cylinders 37 located on both sides of the pressure-release assembly 33. The telescopic rod of the vertical cutting cylinder 36 is set downward and connected to the fixed shaft 35 through the vertical cutting rotating support arm 38. The telescopic rod of the pressure-release cylinder 37 is set downward and connected to the pressure-release rotating support arm 333 of the pressure-release assembly 33. The pressure-release rotating support arm 333 is rotatably connected to the fixed shaft 35 through bearings.

[0049] Through the above design, the pressure cylinder 37 drives the pressure frame 331 to rotate around the fixed shaft 35, and the vertical cutting cylinder 36 drives the vertical cutting blade 34 to rotate around the fixed shaft 35, so that the pressure rod 332 presses on the strip of tofu, which facilitates the rotational cutting of the vertical cutting blade 34.

[0050] like Figures 5 to 7As shown, the rotary lifting mechanism of the present invention includes fixed plates 71 mounted on both ends of a long rotating shaft 6. The fixed plates 71 are connected to the box-dropping fixing frame 102 via lifting cylinders 72. One side of one fixed plate 71 is provided with a fork rotating cylinder 73, the telescopic rod of which is connected to a fork rotating rack 731. The other side is provided with a pallet rotating cylinder 74, the telescopic rod of which is connected to a pallet rotating rack 741. The fork rotating rack 731 is matched with a fork rotating gear 732 mounted on the long rotating shaft 6. The fork rotating gear 732 is mounted on the long rotating shaft 6 via bearings and is fixed to a U-shaped frame. The pallet rotating rack 741 is matched with the pallet rotating gear 742 mounted on the long rotating shaft 6. The fixed plate 71 is also connected to a lifting slider. The water tank assembly 100 is provided with a lifting guide rail adapted to the lifting slider.

[0051] The tofu tray assembly 4 includes two mounting plates 41 mounted on a long rotating shaft 6. The two mounting plates 41 are connected by a parallel guide rail 42. Multiple tofu trays 43 are tightly mounted on the parallel guide rail 42. A limiting rod 44 of fixed length is provided between two adjacent tofu trays 43. Two limiting plates 45 mounted on the long rotating shaft 6 are spaced apart on the outermost tofu tray 43. An insertion block 46 for connecting with a pulling mechanism is provided between the two limiting plates 45. A tofu baffle 711 is also fixed between the two fixed plates 71 to catch tofu that accidentally slips off the tofu tray 43.

[0052] The two ends of the receiving box 8 are connected to the water tank assembly 100 via bearings with seats. The water tank assembly 100 located on both sides of the receiving box 8 is fixed with a receiving box cylinder 81. The telescopic rod of the receiving box cylinder 81 is set downward and connected to the two ends of the receiving box 8 via the receiving box rotating support arm.

[0053] Through the above design, the present invention enables the fork rotation cylinder 73 to drive the fork rotation rack 731 to move up and down, the fork rotation rack 731 to drive the fork rotation gear 732 to rotate, and the fork rotation gear 732 to drive the U-shaped frame of the fork assembly 5 to rotate, so that the two comb plates 51 can rotate upward to engage with the comb teeth 82 of the receiving box piece 8, and can also rotate downward to place the inverted tofu box on the tofu on the tofu tray assembly 4, or rotate 180 degrees together with the tofu tray assembly 4; the tray rotation cylinder 74 drives the tray rotation rack 741 to move up and down, the tray rotation rack 741 to drive the tray rotation gear 742 to rotate, thereby driving the tofu tray assembly 4, which is fixed on the long rotating shaft 6, to rotate 180 degrees;

[0054] During the boxing process, after the tofu is cut into pieces, the piston rod of the opening cylinder 461 of the opening mechanism extends, causing the connecting piece 462 and the insertion block 46 fixed to the connecting piece 462 to move outward. When the distance between the outermost tofu tray 43 and the adjacent tofu tray 43 reaches the length of the limit rod, the tofu tray 43 adjacent to the outermost tofu tray 43 begins to move, and so on, until all tofu trays 43 have moved to their corresponding positions. At this time, the position of the tofu tray 43 corresponds vertically to the position of the comb plate 51 of the fork assembly 5, which facilitates the subsequent box-closing operation.

[0055] like Figure 9 As shown, the box-dropping mechanism 1021 of the present invention includes, from bottom to top, a box-insertion frame, a fixed main plate 1023 fixedly connected to a box-dropping fixing frame 102, and a storage rod 1024 disposed on the fixed main plate 1023. The box-insertion frame includes two fixed long rods 1022 spaced apart, which are connected by a plurality of box-insertion long rods 1025 spaced apart. Each box-insertion long rod 1025 has a box-insertion cone rod 1026 at its top, which exists between the box-insertion long rod 1025 and the fixed main plate 1023. Within the gap between the plates 1023, a box guide rod 1027 is provided on one side of the box insertion rod 1025. A box insertion slider matching the box guide rod 1027 is provided at the bottom of the fixed main plate 1023. A box insertion cylinder 1028 is provided at the top of the fixed main plate 1023. The telescopic rod of the box insertion cylinder 1028 is fixedly connected to the fixed long rod 1022. Multiple box dropping holes are opened on the fixed main plate 1023. Multiple upward-extending storage rods 1024 are arranged at the four corners of the box dropping holes. Adjacent storage rods 1024 are connected by a short horizontal rod.

[0056] This invention, through the above design, stacks several inverted tofu boxes together and places them into the storage rod 1024, aligning the gap between the bottom tofu box and the second-to-last tofu box's flange with the insertion cone rod 1026. When the fixing main board 1023 moves backward under the drive of the insertion cylinder 1028, the insertion cone rod 1026 gradually inserts into the gap between the flanges. Furthermore, because the insertion cone rod 1026 is smaller at the front and larger at the back, the gap is expanded. Finally, the bottom tofu box separates from the second-to-last tofu box. The friction between the inverted tofu boxes prevents them from easily falling off without external force, and the bottom tofu box falls onto the receiving piece 8. At this point, the fixing main board 1023 moves forward, and the second-to-last tofu box becomes the bottom tofu box, thus repeating the box-dropping cycle.

[0057] like Figure 1 and Figure 10As shown, the scraping mechanism 9 of the present invention includes an L-shaped long scraper 91. The bottom of the L-shaped long scraper 91 is connected to the scraper linear motion mechanism 92 provided on the conveyor 103. The side wall of the L-shaped long scraper 91 is provided with a plurality of side through holes 911 along its length. Each side through hole 911 is fitted with a limiting fixing plate 93. The limiting fixing plate 93 extends out of the L-shaped long scraper 91 and is connected to the side of the conveyor 103.

[0058] Through the above design, the tofu box with its opening facing upward, along with the tofu blocks inside, is placed on the limiting and fixing plate 93 of the scraping mechanism 9. The scraper linear motion mechanism 92 drives the L-shaped long scraper 91 to move toward the conveyor 103. The side wall of the L-shaped long scraper 91 pushes the tofu box onto the conveyor belt of the conveyor 103.

[0059] like Figure 1 and Figure 11 As shown, the pushing mechanism of the present invention includes a first pushing mechanism 21 located at the junction of the cutting area 1 and the pushing area 2, and a second pushing mechanism located above the pushing area 2. The first pushing mechanism 21 includes an X-axis motion module 211 fixed on the water tank assembly 100. A first cylinder lifting mechanism 212 is fixed on the moving plate of the X-axis motion module 211, and the output end of the first cylinder lifting mechanism 212 is connected to the first push plate 213. The second pushing mechanism includes a pushing frame 221 fixed to the water tank assembly 100. The pushing frame 221 is provided with a first linear motion mechanism 222 and a second linear motion mechanism 223. A second cylinder lifting mechanism is fixed on the moving plate of the first linear motion mechanism 222, and the output end of the second cylinder lifting mechanism is connected to the second push plate 202. A third cylinder lifting mechanism is fixed on the moving plate of the second linear motion mechanism 223, and the third cylinder lifting mechanism is connected to the third push plate 203 and the fourth push plate 204 respectively.

[0060] Through the above design, the present invention can simultaneously cut multiple slabs of tofu. After the placement robot pushes the first slab of tofu to the cutting area, the first pusher 213 pushes the first slab of tofu to the inside of the sink assembly. Then the placement robot pushes the second slab of tofu to the outer side of the cutting area.

[0061] The second pusher 202 pushes the two whole slabs of tofu to... Figure 1 and Figure 11 Directly below the third pusher plate 203 and the fourth pusher plate 204, the third pusher plate 203 and the fourth pusher plate 204 push the two plates of tofu brought in by the second pusher plate 202 to the connection between the cutting area 3 and the area to be cut 2 for strip cutting;

[0062] Then, the second pusher 202 will push the two whole plates of tofu that were transported for the second time to the cutting area 3. During the second push, the fourth pusher will continue to push the two whole plates of tofu that were transported for the first time, and push the tofu that was cut into strips for the first time to the tofu tray assembly 4 for block cutting. This cycle continues.

[0063] like Figure 5 As shown, the opening mechanism of the present invention includes an opening cylinder 461 fixed on the outside of the water tank assembly 100, and the output end of the opening cylinder 461 is connected to the insertion block 46 via a connector 462.

[0064] Through the above design, the tofu tray assembly 4 and the fork assembly 5 will not be obstructed when rotating 180 degrees around the long rotating shaft 6.

[0065] like Figure 2 and Figure 5 As shown, the pushing area 2 of the present invention is further provided with a transverse blocking member 23 and a longitudinal blocking member 24. The transverse blocking member 23 includes a fourth cylinder lifting mechanism 231 and a transverse blocking plate 232 connected to the output end of the fourth cylinder lifting mechanism 231. The longitudinal blocking member 24 includes a fifth cylinder lifting mechanism 241 and a longitudinal blocking plate 242 connected to the output end of the fifth cylinder lifting mechanism 241.
