Description

Technical Field

[0001] This utility model relates to the field of soft tofu processing technology, and in particular to a soft tofu production line. Background Technology

[0002] Southern tofu, also known as gypsum tofu, uses gypsum solution as a setting agent. Compared to northern tofu, it has a softer and more delicate texture. Making tofu with gypsum is common in rural areas. The main process is the same as making tofu with brine, vinegar, or sweet leaf juice, except that gypsum is used instead of brine, vinegar, or sweet leaf juice. It is white in color, has a delicate and soft texture, is rich in protein, and has high nutritional value. Regular consumption of gypsum tofu can make one's complexion whiter and smoother.

[0003] On existing soft tofu production lines, the curd-spraying device sprays the curdled tofu into a carrier frame, and then presses water to form soft tofu.

[0004] A layer of gauze is pre-covered inside the carrying frame. After the tofu pudding is tightly held by the gauze, the outer edge of the gauze needs to be folded over to cover the top of the tofu pudding. Then, it is pressed by a pressure device. The above-mentioned operation of folding the gauze is usually done manually by bending over. For the fast production speed of the production line, it is physically demanding to bend over for a long time.

[0005] To address the aforementioned issues, a soft tofu production line is proposed. Utility Model Content

[0006] The main purpose of this utility model is to provide a soft tofu production line that solves the problems mentioned in the background art.

[0007] The objective of this utility model can be achieved by adopting the following technical solution:

[0008] A soft tofu production line includes a conveyor frame, a fixed frame is fixed across the top of the conveyor frame, and a lifting mechanism is fixed to the top inner side of the fixed frame by screws. The lifting mechanism is equipped with a folding mechanism.

[0009] The lifting mechanism includes a lifting hydraulic cylinder that is detachably installed with the fixed frame. A lifting plate is fixedly installed on the output end of the lifting hydraulic cylinder. The four outer corners of the lifting plate are formed with guide angles that are slidably connected to the four columns on the outer side of the fixed frame.

[0010] The folding mechanism includes a negative pressure pump fixed on the four corners of the lifting plate. A telescopic air pipe is sleeved on the input end of the negative pressure pump. A negative pressure suction roller is sealed to the free end of the telescopic air pipe. Folding frames are also fixed on both sides of the negative pressure suction roller.

[0011] A tofu-carrying mechanism is also placed on the conveyor rollers of the conveyor frame.

[0012] Furthermore, the tofu-supporting mechanism includes an outer support frame made of plastic, and an inner support frame made of metal is slidably disposed inside the outer support frame. Gauze is overlapped in the inner walls of both the inner and outer support frames.

[0013] Furthermore, a controller is fixed at the center of the lifting plate, surrounding the output end of the lifting hydraulic cylinder. A folding motor, which is fixedly installed on the lifting plate, is connected to the outside of the controller by wires. A drive gear is keyed to the output end of the folding motor, and a driven gear meshes with one side below the drive gear.

[0014] Furthermore, a rotating shaft is fixedly inserted through the driven gear, and both ends of the rotating shaft are rotatably connected to the inner cavity wall of the lifting plate. The top of the folding frame is fixedly sleeved on the rotating shaft.

[0015] Furthermore, the telescopic air pipe passes through the folding frame and communicates with the interior of the negative pressure suction roller, and the outer wall of the negative pressure suction roller is provided with several negative pressure holes that communicate with the inner cavity.

[0016] Furthermore, two sets of columns of the fixing frame are symmetrically equipped with limiting mechanisms on their outer walls. The limiting mechanism includes a limiting motor, and a limiting plate is sleeved on the output shaft of the limiting motor. The limiting plate is not higher than the top of the outer bearing frame.

[0017] The beneficial technical effects of this utility model are as follows:

[0018] This invention, by setting a lifting mechanism and a folding mechanism above the tofu carrier frame, can grip the four corners of the gauze with a negative pressure suction roller, and then use the flipping action of the folding motor and folding frame to fold the four corners of the gauze in sequence to cover the tofu pudding. This replaces the manual work of folding the gauze, saves labor costs, and reduces physical exertion. Attached Figure Description

[0025] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0026] like Figures 1-4 As shown, this embodiment provides a soft tofu production line, including a conveyor frame. A fixed frame 2 is fixed across the top of the conveyor frame 1. A lifting mechanism 4 is fixed to the top of the inner side of the fixed frame 2 by screws. A folding mechanism 5 is provided on the lifting mechanism 4. The lifting mechanism 4 includes a lifting hydraulic cylinder 401 that is detachably installed with the fixed frame 2. A lifting plate 402 is fixedly installed on the output end of the lifting hydraulic cylinder 401. Guide corners 403 are formed at the four outer corners of the lifting plate 402 and are slidably connected to the four columns on the outer side of the fixed frame 2. The folding mechanism 5 includes a negative pressure pump 507 fixed on the four corners of the lifting plate 402. A telescopic air pipe 508 is sleeved on the input end of the negative pressure pump 507. A negative pressure suction roller 501 is sealed to the free end of the telescopic air pipe 508. Folding frames 506 are also fixed on both sides of the negative pressure suction roller 501. A tofu carrying mechanism 3 is also placed on the conveyor roller of the conveyor frame 1.

[0027] In the above structure, the feeding side of the fixed frame 2 is equipped with a brain-splashing device on the soft tofu production line, which pumps the tofu brain after coagulation to the tofu carrying mechanism 3 with gauze 303, and each group of tofu carrying mechanisms 3 is spaced 20cm apart, and the conveyor frame 1 controls the automatic stop processing.

[0028] The tofu support mechanism 3 includes an outer support frame 301 made of plastic, and an inner support frame 302 made of metal is slidably disposed inside the outer support frame 301. Gauze 303 is overlapped in the inner walls of both the inner support frame 302 and the outer support frame 301. The top of the inner support frame 302 is higher than the outer support frame 301, and the inner bottom is a fully open structure, sharing the inner bottom with the outer support frame 301. The gauze 303 is laid flat with the inner bottom and contacts the four inner walls of the inner support frame 302, with the outer side folded over the top of the inner support frame 302.

[0029] A controller 7 is fixed at the center of the lifting plate 402, surrounding the output end of the lifting hydraulic cylinder 401. The controller 7 is connected to a tilting motor 505 fixedly installed on the lifting plate 402 via wires. The output end of the tilting motor 505 is keyed to a drive gear 504. A driven gear 503 meshes with the drive gear 504 on one side below it. The four sets of negative pressure pumps 507 and the four sets of tilting motors 505 are all pre-programmed and controlled by the controller 7, and work independently in sequence. Each set of negative pressure pumps 507 independently follows the tilting motor 505 connected to it.

[0030] A rotating shaft 502 is fixedly inserted through the driven gear 503. Both ends of the rotating shaft 502 are rotatably connected to the inner wall of the lifting plate 402. The top of the folding frame 506 is fixedly sleeved on the rotating shaft 502. The initial position of the folding frame 506 is located 0.5mm outside the outer wall of the outer support frame 301. After moving down, the negative pressure suction roller 501 can contact the outer wall of the gauze 303.

[0031] The telescopic air tube 508 passes through the folding frame 506 and connects to the inside of the negative pressure suction roller 501. Several negative pressure holes communicating with the inner cavity are opened on the outer wall of the negative pressure suction roller 501. The telescopic air tube 508 can extend as the folding frame 506 is flipped. The folding frame 506 is Z-shaped. When flipped, the gauze 303 can slide on the negative pressure suction roller 501 because it is pressed by the tofu curd, but it is still gripped by the negative pressure. As the negative pressure suction roller 501 rotates to the maximum angle, the gauze 303 falls off the negative pressure hole and is folded to the other side.

[0032] Limiting mechanisms 6 are symmetrically installed on the outer walls of two sets of columns of the fixed frame 2. The limiting mechanism 6 includes a limiting motor 602. A limiting plate 601 is sleeved on the output shaft of the limiting motor 602. The limiting plate 601 is not higher than the top of the outer bearing frame 301. The limiting plate 601 serves to limit the outer bearing frame 301.

[0033] Working principle of this device: When in use, this device is connected to an external power source, and the controller 7 is connected to the main control equipment of the soft tofu production line to achieve linkage with other equipment.

[0034] The outer support frame 301 carries the inner support frame 302 on the conveyor frame 1. Simultaneously, gauze 303 covers the bottom of the outer support frame 301 and the four sides of the inner support frame 302. After being filled with coagulated tofu, the gauze is moved to the side of the limit plate 601 and the conveyor frame 1 stops. The lifting hydraulic cylinder 401 pushes the lifting plate 402 downwards, and the guide angle 403 moves vertically downwards along the four pillars of the fixed frame 2. The negative pressure suction roller 501 moves down close to the outer wall of the outer support frame 301 to a suitable position at the bottom of the outer wall of the gauze 303. The negative pressure pump 507 draws negative pressure inside the negative pressure suction roller 501 through the telescopic air pipe 508. Under the action of negative pressure, the channels on the outer wall of the negative pressure suction roller 501 grip the outer wall of the gauze 303. The lifting hydraulic cylinder 401 rises, and the four sides of the gauze 303 are lifted. Then, the controller 7 controls four sets of folding motors 505 to work sequentially, driving the drive gear 504 to drive the driven gears. Gear 503 rotates, driving shaft 502 to rotate. Shaft 502 drives folding frame 506 to flip towards the bottom of lifting plate 402. Then, negative pressure suction roller 501 drives the gripped gauze 303 to fold towards the other side of the top of inner support frame 302. As negative pressure suction roller 501 rotates, the outer wall of gauze 303 slides on the outer wall of negative pressure suction roller 501. As negative pressure suction roller 501 rotates to its maximum angle, gauze 303 falls off the outer wall of negative pressure suction roller 501. One side of gauze 303 is folded to the other side of the outer wall of inner support frame 302 and outer support frame 301. Then the current negative pressure suction roller 501 is reset. The corresponding negative pressure suction roller 501 on the other side begins to fold the other side of gauze 303 to cover the gauze 303 in the same way. Then it is reset. The other two sets of opposite gauze 303 sides are folded and covered in sequence to complete the sealing of tofu pudding.

[0035] The above structure enables automatic completion of the gauze 303 packaging process before pressing and dehydrating tofu pudding, replacing the traditional manual operation, improving work efficiency, saving manpower, and reducing labor costs.

[0036] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
