Description

Technical Field

[0001] This utility model relates to the field of automatic cutting and packaging, specifically an automatic tofu cutting and packaging machine. 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] The existing tofu cutting process has the following two problems: 1. Existing technology often uses a cylinder to drive a pusher plate to move a whole board of tofu in water until it is delivered to the cutting area. Although this method is simple in structure, if the pusher plate accidentally hits the whole board of tofu, it can cause the tofu to break, affecting the yield. In addition, this method requires the pushing action to be completed in water, where bacteria can easily grow. 2. In the existing technology, the tofu is first flipped from the mold box onto a flat plate, and then the plate is manually held and placed in the cutting area. During this process, the position of the tofu on the plate will shift, resulting in inconsistent tofu sizes in the subsequent cutting process. Furthermore, the thermal expansion and contraction of the tofu in water also leads to unstable tofu cutting dimensions.

[0004] Therefore, this utility model proposes an automatic tofu cutting and packaging machine to solve the above problems. Utility Model Content

[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] An automatic tofu cutting and packaging machine includes:

[0040] The system comprises a parallel conveying mechanism 1 and an accelerating conveying mechanism 2. The parallel conveying mechanism 1 is equipped with a tofu cutter 6 above it, and the accelerating conveying mechanism 2 is equipped with a pusher plate 7 above it. The parallel conveying mechanism 1 is equipped with a fixed frame 100 on its right side. The fixed frame 100 has a flipping mechanism 200 for flipping the tofu box fixed on one side and a conveying motor 300 for conveying tofu fixed on the other side. The accelerating conveying mechanism 2 is equipped with a tofu box conveying mechanism 8 on its left side. The tofu box conveying mechanism 8 is equipped with a tofu tray opening mechanism 81 above it, which cooperates with the pusher plate 7 to push the cut tofu blocks into the tofu box of the tofu box conveying mechanism 8. The tofu box conveying mechanism 8 is also equipped with a box dropping mechanism 9 at its end for lowering the tofu box.

[0041] The parallel conveying mechanism 1 and the accelerating conveying mechanism 2 are arranged in parallel. The accelerating conveying mechanism 2 has a fixed frame 100 on one side, a turning mechanism 200 for turning the tofu box is fixed on one side of the fixed frame 100, and a conveying motor 300 for conveying tofu is fixed on the other side.

[0042] The flat conveying mechanism 1 includes two flat mounting plates 11 spaced apart. A flat conveying roller 12 is installed between the lower parts of the two flat mounting plates 11, a flat conveying support roller 13 is installed between the sides, and a flat support plate 14 is installed between the top parts. The flat conveying roller 12, the flat conveying support roller 13, and the flat support plate 14 are connected by a flat conveying belt 15. A flat tensioning device 3 is provided on the outer side of the flat conveying belt 15.

[0043] The accelerating conveying mechanism 2 includes two spaced-apart accelerating mounting plates 21. An accelerating conveying roller 22 is installed between the lower parts of the two accelerating mounting plates 21, an accelerating conveying support roller 23 is installed between the sides, and an accelerating support plate 24 is installed between the tops. The accelerating conveying roller 22, the accelerating conveying support roller 23 and the accelerating support plate 24 are connected by an accelerating conveying belt 25. An accelerating tensioning device 4 is provided on the outside of the accelerating conveying belt 25.

[0044] In the traditional tofu cutting process, a cylinder drives a scraper, which pushes the tofu to cut. This process is carried out in water, where buoyancy reduces friction between the tofu and the scraper. This new invention utilizes a flat-speed conveyor belt 15 to transport the tofu, which is cut into pieces on the conveyor belt 15 simultaneously, improving efficiency. After cutting, an accelerating conveyor belt 25 speeds up the transport, quickly conveying the previous row of tofu pieces to the junction of the tofu tray opening mechanism 81 and the accelerating conveyor belt 25. The pusher plate 7 above the accelerating conveyor belt 25 begins its first stroke, pushing the tofu pieces on the accelerating conveyor belt 25 to the front end of the tofu tray opening mechanism 81. Then, the tofu tray opening mechanism 81 begins its opening action, horizontally separating each piece of tofu by a set distance and opening it from the tofu tray. The tofu compartments 82 above mechanism 81 correspond one-to-one. Push plate 7 begins the second stage of its stroke, pushing the tofu blocks from the front end of the tray 811 of tofu tray opening mechanism 81 into the tofu compartment 82. Then, tofu tray opening mechanism 81 moves backward, pulling out the tray 811. The tofu naturally falls into the tofu box of tofu box conveying mechanism 8. The end of tofu box conveying mechanism 8 is equipped with a box dropping mechanism 9. The box dropping mechanism 9 lowers tofu boxes at a set time, so that multiple tofu boxes correspond one-to-one with tofu compartments 82, ensuring that when the tray 811 of tofu tray opening mechanism 81 is pulled out, the tofu blocks fall accurately into the tofu boxes.

[0045] This conveying method involves only a small amount of friction when the final push plate 7 and the tofu tray 811 are engaged in the boxing mechanism 81, further ensuring the integrity of the tofu. A flat-speed tensioning device 3 is provided on the outer side of the flat-speed conveyor belt 15 to prevent tofu breakage caused by jamming during transport between the flat-speed conveyor belt 15 and the flat-speed conveyor roller 12, flat-speed conveyor support roller 13, and flat-speed support plate 14. Similarly, an acceleration tensioning device 4 is provided on the outer side of the acceleration conveyor belt 25 to ensure the stability of the acceleration conveyor belt 25 during transport and to prevent the conveyor belt from slipping due to excessive looseness.

[0046] Specifically, the output end of the conveyor motor 300 is connected to the conveyor belt roller 301. Two interconnected conveyor belt side mounting plates 400 are installed at both ends of the conveyor belt roller 301. Two spaced-apart lower conveyor rollers 302 and two spaced-apart upper conveyor rollers 303 are provided above the conveyor belt roller 301. The lower conveyor rollers 302 and upper conveyor rollers 303 are fixed at both ends on the conveyor belt side mounting plates 400. The conveyor belt roller 301, the two upper conveyor rollers 303 and the two lower conveyor rollers 302 are sequentially conveyed and connected by the conveyor belt 500. The conveyor belt side mounting plate 400 away from the conveyor motor 300 is connected to the output end of the flipping mechanism 200.

[0047] The upper conveyor roller 303 is provided with a tofu box clamping cylinder 600 on its outer side, and the tofu box clamping cylinder 600 is fixed on the conveyor belt side mounting plate 400.

[0048] In use, the clamping cylinder 600 is held vertically downwards. The operator first opens the covering cloth and places the entire tofu-shaped box 800 on the lifting machine 801. The lifting machine 801 then lifts the tofu-shaped box 800, ensuring the tofu is flush against the conveyor belt 500. The clamping cylinder 600 then clamps the tofu, and the flipping mechanism 200 flips the box 180 degrees counter-clockwise. At this point, the tofu-shaped box 800 is inverted on the conveyor belt 500. The operator removes the box and covering cloth. The drive motor 300 then drives the conveyor belt rollers 301, two upper conveyor rollers 303, and two lower conveyor rollers 302, transporting the tofu from the conveyor belt 500 to the flat conveyor mechanism 1, where it can be cut. This invention achieves zero pollution and zero contact from the tofu placement process, ensuring food safety while improving efficiency.
