Description

Technical Field

[0001] The present invention relates to the technical field of fermented bean curd processing, and particularly to a pickling device for fermented bean curd processing. Background Art

[0002] In the production process of fermented bean curd, a whole piece of bean curd embryo needs to be cut into multiple small pieces of bean curd embryo blocks. The bean curd embryo blocks are placed in a fermentation sieve and grow moldy hairs through fermentation. Then, the bean curd embryo blocks are transferred to a pickling basin, salt is sprinkled on the bean curd embryo blocks, and then the second layer of bean curd embryo blocks is stacked and salt is sprinkled again. The above process is repeated to pickle the bean curd embryo blocks.

[0003] However, the above production process is mostly carried out manually, with low production efficiency and high labor costs. In addition, during the process of workers transferring the bean curd embryo blocks, the bean curd embryo blocks are likely to be broken due to improper operation. During the process of sprinkling salt, due to the instability of manual operation, the amount of salt in each layer is inconsistent and the manual application in a single layer is uneven, resulting in unequal salt amounts on the surface of the bean curd embryo blocks. This will cause inconsistent salt content ratios in the pickled bean curd embryo blocks, affecting the quality of the final fermented bean curd. Moreover, because the hands come into contact with salt, it causes certain harm to the hands, resulting in difficulties in recruiting workers for fermented bean curd manufacturers or even no workers available.

[0074] The technical solutions in the embodiments of the present invention will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0075] Refer to Figure 1 and Figure 2 , which shows a pickling device for fermented bean curd processing, including a scraping embryo device C0, an inverted blanking mechanism D0, a transfer mechanism A0, and a salt sprinkling mechanism B0; wherein, the scraping embryo device C0 is a scraping embryo mechanism C10 for loosening the bean curd embryo blocks in the fermented sieve 200; the inverted blanking mechanism D0 is used to separate the bean curd embryo blocks from the fermented sieve 200 and place the bean curd embryo blocks on a top plate D30; the transfer mechanism A0 includes a suction cup A10, and the suction cup A10 transfers the bean curd embryo blocks on the top plate D30 to the pickling basin 300 by means of vacuum adsorption; the salt sprinkling mechanism B0 is used to sprinkle salt onto the bean curd embryo blocks in the pickling basin 300.

[0076] In this embodiment, first, the embryo scraping device C0 is used to loosen the tofu embryo blocks in the fermentation sieve 200, so that the tofu embryo blocks no longer adhere to the inner bottom surface of the fermentation sieve 200; then, the turnover and discharging mechanism D0 is used to pour the tofu embryo blocks in the fermentation sieve 200 onto a top plate D30, so that the tofu embryo blocks are separated from the fermentation sieve 200; then, the suction cup A10 on the transfer mechanism A0 is used to transfer the tofu embryo blocks to the pickling basin 300, and finally, the salt spreading mechanism B0 is used to sprinkle salt onto the tofu embryo blocks in the pickling basin 300; wherein, generally, only a single layer of multiple tofu embryo blocks is laid in the fermentation sieve 200, and the transfer mechanism A0 transfers the tofu embryo blocks into the pickling basin 300 layer by layer, and the salt spreading mechanism B0 sprinkles salt onto the tofu embryo blocks in each layer. After the tofu embryo blocks in the pickling basin 300 reach a certain number of layers, a new pickling basin 300 is replaced. This pickling equipment can effectively save labor costs, has high transfer efficiency and stacking efficiency of tofu embryo blocks, does not require manual salt spreading, avoids harm to workers' hands, and avoids the situation that the tofu embryo blocks are easily broken due to manual transfer of the tofu embryo blocks.

[0077] Reference Figures 5 - 7 , to facilitate the separation of the tofu embryo blocks from the fermentation sieve 200, in this embodiment, the turnover and discharging mechanism D0 includes a turnover frame body D10 and a fifth driver D40. A transmission shaft D20 arranged along the axial direction is provided on the turnover frame body D10; a receiving space D11 is arranged inside the turnover frame body D10. An opening D12 is provided at one end of the receiving space D11 along the axial direction of the transmission shaft D20 for the fermentation sieve 200 to enter and exit; the receiving space D11 includes a sliding chamber D111 and an avoidance chamber D112 distributed along the radial direction of the transmission shaft D20. Sliding support grooves are formed on both sides inside the sliding chamber D111, and both sides of the fermentation sieve 200 are slidably arranged in the sliding support grooves; a top plate D30 that can move along its radial direction is arranged inside the receiving space D11, and the top plate D30 is driven to move by a sixth driver D31; the fifth driver D40 is in transmission connection with the transmission shaft D20 to drive the turnover frame body D10 to rotate around the transmission shaft D20.

[0078] Regarding this turnover and discharging mechanism D0, reference Figure 7, in the initial state, the avoidance chamber D112 is above and the sliding chamber D111 is below. At this time, the top plate D30 is located in the avoidance chamber D112. The fermentation sieve 200 containing the tofu embryo blocks is pushed into the sliding chamber D111 from the opening D12. The two sides of the fermentation sieve 200 are limited by the sliding support grooves, so that the fermentation sieve 200 cannot enter the avoidance chamber D112. Then, the top plate D30 is driven to move by the sixth driver D31, so that the top plate D30 descends into the sliding chamber D111 and presses the tofu embryo blocks against the bottom of the fermentation sieve 200. Then, the fifth driver D40 is used to drive the flipping frame D10 to rotate 180° around the rotating shaft, so that the sliding chamber D111 is above and the avoidance chamber D112 is below. Since the tofu embryo blocks are pressed, the tofu embryo blocks will not fall during the flipping process, and the tofu embryo blocks will be supported by the top plate D30 after the flipping is completed. Then, the top plate D30 descends and brings the tofu embryo blocks into the avoidance chamber D112, so that the tofu embryo blocks are separated from the fermentation sieve 200. Finally, the fermentation sieve 200 is withdrawn from the sliding chamber D111. In this way, the flipping and blanking mechanism D0 takes out the tofu embryo blocks in the fermentation sieve 200 by flipping at one time, with high blanking efficiency and not easily breaking the tofu embryo blocks. It can automatically realize the separation of the tofu embryo blocks from the fermentation sieve 200, which can effectively reduce the labor cost. Of course, the pressure of the top pressing on the tofu embryo blocks should be appropriate to avoid crushing the tofu embryo blocks.

[0079] Regarding the flipping and blanking mechanism D0, to facilitate limiting the fermentation sieve 200 in the sliding chamber D111, refer to Figure 5 and Figure 6 , the sliding support grooves include a first support surface and a second support surface arranged oppositely, and the first support surface and the second support surface respectively support the upper and lower ends of the fermentation sieve 200. To improve the stability of the transmission shaft D20 during rotation, refer to Figure 5 , the transmission shaft D20 is rotatably installed on the rotating seat D21, and a bearing (not marked in the figure) is provided between the transmission shaft D20 and the rotating seat D21. In this embodiment, the fifth driver D40 is a motor, and the fifth driver D40 is connected to the transmission shaft D20 through a synchronous belt (not marked in the figure). One side of the avoidance chamber D112 away from the sliding chamber D111 is provided with a connecting plate (not marked in the figure), and the sixth driver D31 is a cylinder arranged outside the connecting plate.

[0080] Among them, an opening D13 communicating with the outside is opened on one side of the sliding chamber D111 away from the avoidance chamber D112. In this way, the suction cup A10 on the transfer mechanism A0 can take away the tofu embryo blocks on the top plate D30 through the opening D13.

[0081] In addition, to facilitate the connection of the flipping and blanking mechanism to different workstations, refer to Figure 3 and Figure 4 . There are multiple flipping and blanking mechanisms. The multiple flipping and blanking mechanisms are conveyed by a conveying mechanism to change their positions, so as to connect the flipping and blanking mechanism to different workstations. Specifically in this embodiment, the conveying mechanism includes a fixed seat, and a rotatable turntable is provided on the fixed seat. The turntable is driven to rotate by an eighth driver; the multiple flipping and blanking mechanisms are arranged equidistantly along the circumference on the turntable. The eighth driver can be a motor.

[0082] Refer to Figures 8 - 12 . In this embodiment, the embryo scraping device C0 includes a first conveying mechanism C20 and an embryo scraping mechanism C10; the first conveying mechanism C20 is used to convey the fermentation sieve 200 containing tofu embryo blocks; the embryo scraping mechanism C10 is arranged above the first conveying mechanism C20. The embryo scraping mechanism C10 includes a liftable mounting plate C11, and two movable embryo scraping plates C12 are provided on the mounting plate C11. The two embryo scraping plates C12 are arranged in parallel and each embryo scraping plate C12 is driven to move by a first driver C13. Briefly speaking, the embryo scraping device C0 uses the first conveying mechanism C20 to convey the fermentation sieve 200 containing tofu embryo blocks to below the embryo scraping mechanism C10. The mounting plate C11 on the embryo scraping mechanism C10 descends so that the two embryo scraping plates C12 are located on both sides of these tofu embryo blocks. The two embryo scraping plates C12 are driven to move respectively by the first driver C13. The two embryo scraping plates C12 push these tofu embryo blocks to move in the fermentation sieve 200, so that the tofu embryo blocks are no longer adhered to the fermentation sieve 200, thus facilitating the removal of the tofu embryo blocks from the fermentation sieve 200. In this embodiment, refer to Figure 11 . The first driver C13 uses a cylinder. The fermentation sieve 200 can be a fermented bean curd fermentation sieve 200 with a publication number of CN207940299U. Among them, the output end of the first conveying mechanism C20 is connected to the opening D12 of the flipping frame body D10 to facilitate the feeding of the fermentation sieve into the sliding chamber D111.

[0083] Regarding this embryo scraping device C0, in this embodiment, the first conveying mechanism C20 uses a double-belt conveyor. Refer to Figure 9, a first blocking mechanism C30 for blocking the advancement of the fermentation sieve 200 is provided on the first conveying mechanism C20 to intercept the fermentation sieve 200 below the embryo scraping mechanism C10; specifically, the first blocking mechanism C30 includes a first blocking member C31 and a second driver C32 for driving the first blocking member C31 to lift and lower. The second driver C32 can adopt a cylinder. When it is necessary to block the fermentation sieve 200, the second driver C32 drives the first blocking member C31 to rise, so that the first blocking member C31 protrudes from the first conveying mechanism C20, enabling the fermentation sieve 200 to be blocked; when the scraping operation of the tofu embryo blocks in the fermentation sieve 200 is completed, the second driver C32 drives the first blocking member C31 to descend, so that the first blocking member C31 is lower than the conveying support surface on the first conveying mechanism C20, allowing the fermentation sieve 200 to be conveyed through.

[0084] Regarding this embryo scraping device C0, when the fermentation sieve 200 is conveyed on the first conveying mechanism C20, it may shift in position due to vibration; refer to Figures 8 - 11 , in this embodiment, the embryo scraping mechanism C10 further includes a positioning assembly C14 provided above the mounting plate C11, and the positioning assembly C14 is used to realize the left-right positioning of the fermentation sieve 200 in the conveying direction; specifically, the positioning assembly C14 is lifted and lowered synchronously with the mounting plate C11; the positioning assembly C14 includes a positioning plate C141 and limiting members C142 provided on both sides of the positioning plate C141. The positioning assembly C14 restricts the fermentation sieve 200 between the limiting members C142 on both sides, so that the two embryo scraping plates C12 can be located on both sides of these tofu embryo blocks after descending; among them, the limiting member C142 includes a vertical limiting portion C143, and a guiding surface C144 is formed on the inner wall surface of the vertical limiting portion C143. The distance between the two guiding surfaces C144 on the vertical limiting portions C143 on both sides changes from wide to narrow from bottom to top. In this way, when the positioning assembly C14 descends, the side frame of the fermentation sieve 200 is guided and limited through the guiding surfaces C144 on both sides, so as to adjust and position the left-right position of the fermentation sieve 200 in the conveying direction; among them, the direction in which the embryo scraping plate C12 pushes the tofu embryo block to move is the same as the direction in which the fermentation sieve 200 is positioned. In this way, when the left-right position of the fermentation sieve 200 is limited, it can be avoided that the two embryo scraping plates C12 drive the fermentation sieve 200 to move when pushing the tofu embryo block to move.

[0085] Regarding this embryo scraping device C0, to adapt to the positioning of fermentation sieves 200 of different sizes, the position of the vertical limiting portion C143 on the positioning plate C141 is adjustable. Refer to Figure 10 and Figure 11, in this embodiment, the limiting member C142 is provided with a long hole and is fixed to the positioning plate C141 by bolts; in this way, the position of the limiting member C142 on the positioning plate C141 can be adjusted. To improve the stability of the embryo scraping plate C12 during movement, a guiding structure can be added between the embryo scraping plate C12 and the mounting plate C11; refer to Figure 11 , in this embodiment, a plurality of insertion strips C111 are provided on both sides of the mounting plate C11, and insertion holes (not shown) are provided on the embryo scraping plate C12. The shapes of the insertion strips C111 and the insertion holes correspond to each other, and the insertion strips C111 are slidably inserted into the insertion holes. To facilitate the lifting of the mounting plate C11, refer to Figure 8 and Figure 9 , the mounting plate C11 is driven to lift by a first electric push rod C15, and the first electric push rod C15 is arranged on the frame 100.

[0086] Regarding the embryo scraping device C0, to facilitate docking with the flipping and blanking mechanism, refer to Figure 9 , a pushing mechanism C40 for pushing the fermentation sieve 200 out of the first conveying mechanism C20 is provided on the first conveying mechanism C20; wherein, when the fermentation sieve 200 moves to the end of the first conveying mechanism C20, as the fermentation sieve 200 is conveyed, the contact area between the fermentation sieve 200 and the conveying mechanism C20 becomes smaller and smaller, resulting in the conveying mechanism C20 not easily sending the fermentation sieve 200 to the flipping and blanking mechanism; therefore, the pushing mechanism C40 can be used to push the fermentation sieve 200 so that the fermentation sieve 200 can smoothly enter the opening D12 of the flipping frame D10. Refer to again Figure 12 , in this embodiment, the pushing mechanism C40 includes a pushing seat C41 and a pushing cylinder C43 for driving the pushing seat C41 to move. A rotating shaft C412 is provided on the pushing seat C41, and a pushing claw C42 is hinged on the rotating shaft C412. The upper end of the pushing claw C42 is located above the rotating shaft C412, and the lower end of the pushing claw C42 is located below the rotating shaft C412. The weight of the lower end of the pushing claw C42 is greater than the weight of the upper end of the pushing claw C42; a baffle C411 is provided on the pushing seat C41 on one side of the lower end of the pushing claw C42 to block the rotation of the lower end of the pushing claw C42 in one direction; in the initial state, the lower end of the pushing claw C42 is located below the rotating shaft C412 under the action of gravity, and the upper end of the pushing claw C42 protrudes from the first conveying mechanism C20. Among them, based on the conveying direction, the baffle C411 is located behind the lower end of the pushing claw C42; to Figure 5From the perspective of [description missing in the original], when the tofu embryo blocks in the fermentation sieve 200 complete the embryo scraping operation, as the fermentation sieve 200 continues to be conveyed, the fermentation sieve 200 collides with the upper end of the push claw C42, causing the push claw C42 to rotate clockwise around the rotating shaft C412 and become flat, so that the fermentation sieve 200 can pass through; after the fermentation sieve 200 passes through, under the action of gravity, the lower end of the push claw C42 makes the upper end of the push claw C42 stand upright again. At this time, the pushing cylinder C43 can be used to drive the push seat C41 to move, so that the upper end of the push claw C42 pushes the fermentation sieve 200. Under the action of the baffle C411, the push claw C42 cannot rotate counterclockwise, so that the upper end of the push claw C42 can push the fermentation sieve 200. In addition, to avoid interference, refer to Figure 9 , in this embodiment, a second blocking mechanism C50 is provided at the end of the first conveying mechanism C20, and the structure of the second blocking mechanism C50 can refer to the first blocking mechanism C30.

[0087] Refer to Figures 13 - 15 , the transfer mechanism A0 includes a suction cup A10, a moving mechanism A30 and a lifting mechanism A20; refer to Figure 14 , a first vacuum chamber A11 is formed in the suction cup A10, and a plurality of second vacuum chambers A12 are recessed on the bottom surface of the suction cup A10. The second vacuum chambers A12 are respectively connected to the first vacuum chamber A11 through air holes A13; the first vacuum chamber A11 is connected to a vacuum system (not shown) through a ventilation pipe A16; the moving mechanism A30 is used to drive the suction cup A10 to move in the horizontal direction; the lifting mechanism A20 is used to drive the suction cup A10 to lift. Among them, the moving mechanism A30 driving the suction cup A10 to move in the horizontal direction means that the position of the suction cup A10 on the horizontal plane changes, and it does not limit that the suction cup A10 can only move on a horizontal plane. For example, the suction cup A10 can move along an inclined path.

[0088] Regarding the transfer mechanism A0, a whole layer of tofu embryo blocks is vacuum adsorbed by the suction cup A10. A plurality of second vacuum chambers A12 are recessed at the bottom of the suction cup A10. The adsorption range of the bottom surface of the suction cup A10 should be able to cover a whole layer of tofu embryo blocks, so as to transfer a whole layer of tofu embryo blocks from the top plate to the pickling basin. Among them, even if some of the second vacuum chambers A12 do not completely correspond to the tofu embryo blocks (for example, the second vacuum chamber A12 corresponds to the gap between the tofu embryo blocks or is completely outside the tofu embryo blocks), resulting in the first vacuum chamber A11 being unable to maintain vacuum, as long as the pumping efficiency of the vacuum system is sufficient, the second vacuum chambers A12 corresponding to the tofu embryo blocks can still be kept in vacuum to achieve the adsorption of the tofu embryo blocks. In this way, the transfer efficiency of the tofu embryo blocks is high and it is not easy to cause the tofu embryo blocks to break. Among them, the vacuum system is a prior art and can realize air extraction and air release to generate negative pressure or positive pressure between the suction cup A10 and the tofu embryo blocks. The specific structure and principle are not described in detail here.

[0089] Regarding the transfer mechanism A0, refer to Figure 15 , in this embodiment, the second vacuum chamber A12 is in the shape of a square hole, and a plurality of second vacuum chambers A12 are arranged in an array on the bottom surface of the suction cup A10. In this way, the second vacuum chambers A12 are densely distributed to ensure that each tofu embryo block can be vacuum adsorbed by at least one second vacuum chamber A12. For the convenience of installation, refer to Figure 14 , the suction cup A10 includes an upper disc body A14 and a lower disc body A15. The upper disc body A14 and the lower disc body A15 are connected by bolts, and the first vacuum chamber A11 is formed between the upper disc body A14 and the lower disc body A15.

[0090] Regarding the transfer mechanism A0, for the convenience of moving the suction cup A10, refer to Figure 13 , the moving mechanism A30 includes a slide rail A31, a slide seat A32 slidably arranged on the slide rail A31, and a third driver A33 for driving the slide seat A32 to move along the slide rail A31; the suction cup A10 is arranged on the slide seat A32 in a liftable manner. Among them, the third driver A33 can be a motor, and the movement of the slide seat A32 can be realized through a lead screw mechanism; and for the convenience of realizing the lifting of the suction cup A10, the lifting mechanism A20 includes a lifting seat A21 and a fourth driver (not shown) for driving the lifting seat A21 to lift. The lifting seat A21 is arranged on the slide seat A32 in a liftable manner through a guide rail and guide block assembly, and the suction cup A10 is fixed on the lifting seat A21; among them, the guide rail and guide block assembly includes a guide rail and a guide block, which are respectively installed on the lifting seat A21 and the slide seat A32 to realize the stable lifting of the lifting seat A21 on the slide seat A32; the fourth driver can be a motor, and the lifting of the lifting seat A21 can be realized through a lead screw mechanism.

[0091] Reference Figures 16 - 18 , the salt spreading mechanism B0 includes a silo B10, a salt spreading driving assembly B30 and a moving mechanism A30. An outlet B11 is formed at the bottom of the silo B10; a rotatable rotating member B20 is arranged in the silo B10. The outer peripheral wall of the rotating member B20 blocks the outlet B11, and a plurality of concave structures B21 are recessed in the outer peripheral wall of the rotating member B20; the salt spreading driving assembly B30 is used to drive the rotating member B20 to rotate; the moving mechanism A30 is used to drive the silo B10 and the salt spreading driving assembly B30 to move.

[0092] Generally speaking, the working principle of this salt spreading mechanism B0 is as follows. For reference Figure 18 , the gap between the outer peripheral wall of the rotating member B20 and the inner wall of the silo B10 is not large enough for salt to pass through. When the rotating member B20 does not rotate, the rotating member B20 can block the outlet B11; the salt in the silo B10 will enter the concave structure B21 above the rotating member B20. When the rotating member B20 rotates, the concave structure B21 filled with salt rotates to a position corresponding to the outlet B11, and the salt in the concave structure B21 is poured out under the action of gravity; during the rotation of the rotating member B20, the concave structure B21 continuously repeats the work of loading and pouring salt. The salt spreading speed can be adjusted by adjusting the rotation speed of the rotating member B20; in addition, by moving the silo B10 through the moving mechanism A30, the silo B10 spreads salt during the movement. When the moving speed of the silo B10 and the rotation speed of the rotating member B20 are constant, uniform quantitative salt spreading in the area can be realized, that is, salt can be evenly spread on a whole layer of tofu embryo blocks and the salt amount of each layer can be the same, so that the pickling effect of the tofu embryo blocks is stable; in addition, there is no need for workers to contact salt for a long time, avoiding harm to the workers' hands; the production efficiency is increased and the labor cost is reduced.

[0093] Preferably, for the salt spreading mechanism B0, to improve the processing efficiency, the salt spreading mechanism B0 and the suction cup A10 on the tofu embryo block transfer mechanism A0 move synchronously, and the salt spreading mechanism B0 and the suction cup A10 are located on the same moving path. In this way, the tofu embryo block transfer mechanism A0 is used to transfer a whole layer of tofu embryo blocks from the top plate to the pickling basin. During the process of the tofu embryo block transfer mechanism A0 resetting from above the pickling basin to above the top plate, the salt spreading mechanism B0 will pass above the pickling basin and spread salt, and the transfer action and the salt spreading action are carried out simultaneously, with high production efficiency; in addition, more preferably, both the suction cup A10 and the silo B10 are moved by the same moving mechanism A30, making the structure simple.

[0094] Preferably, for the salt spreading mechanism B0, for reference Figure 17 and Figure 18In this embodiment, the rotating part B20 is cylindrical and rotates around its own axis; wherein the recessed structure B21 can be, for example, a concave hole or a groove. In this embodiment, the recessed structure B21 adopts a groove, the length direction of the groove is arranged along the axial direction of the rotating shaft, and a plurality of grooves are equidistantly arranged on the outer peripheral wall of the rotating part B20 along the circumferential direction; in this way, in different time intervals, the same number of grooves are used to spread salt at the discharge port B11, so as to achieve uniform salt spreading. In addition, the discharge port B11 is strip-shaped, and the discharge port B11 is arranged parallel to the groove; so that all the salt in the groove can be poured out from the discharge port B11. In order to facilitate the rotation of the rotating part B20, refer to Figure 16 In this embodiment, the salt spreading drive assembly B30 includes a motor (not marked in the figure), one end of the rotating member B20 passes through the silo B10, and the motor is connected to the rotating member B20 through a synchronous belt (not marked in the figure).

[0095] In some specific embodiments, in order to further improve the automation of the pickling device, reference is made to Figure 1 and Figure 2 The pickling device also includes a fermentation screen recovery device G0, through which the fermentation screen 200 is extracted from the sliding chamber D111 of the flipping and stripping mechanism D0, without the need for workers to manually extract the fermentation screen 200.

[0096] Regarding the fermentation screen recovery device G0, it includes a screening mechanism G10 and a second conveying mechanism G20; Figure 21 , the sieving mechanism G10 is used to draw out the fermentation sieve in the turning frame D10, and it includes a pulling seat G12 and a pulling cylinder G11 for driving the pulling seat to move; the pulling seat G12 is provided with a pin G121, and the pin G121 is hinged with a claw G13, the upper end of the claw G13 is located above the pin G121, and the lower end of the claw G13 is located below the pin G121, and the weight of the lower end of the claw G13 is greater than the weight of the upper end of the claw G13; the pulling seat G12 is provided with a blocking plate G22 located on one side of the upper end of the claw G13 to prevent the upper end of the claw G13 from rotating in one direction; the second conveying mechanism G20 is used to convey the fermentation sieve 200 drawn out by the sieving mechanism G10;

[0097] Specifically, after the flipping and stripping mechanism D0 receives the fermentation screen 200 from the embryo scraping device C0, the fermentation screen 200 is flipped and stripped, so that the flipping and stripping mechanism D0 is located at Figure 7The final state is that the fermentation sieve 200 is located within the sliding chamber D111, while the top plate D30 and the tofu embryo blocks are located within the avoidance chamber D112; the conveying mechanism F0 conveys the flipping and discharging mechanism D0 such that the flipping and discharging mechanism D0 is docked with the fermentation sieve recovery device G0. At this time, the fermentation sieve 200 is withdrawn from the sliding chamber D111 by the sieve extraction mechanism G10 and sent away by the second conveying mechanism G20; wherein, from the perspective of Figure 21 for illustration, the pulling cylinder G11 pushes the pulling seat G12 to move, such that the pulling seat G12 hits the fermentation sieve 200. The height of the fermentation sieve 200 corresponds to the lower end of the claw G13. When the fermentation sieve 200 collides with the lower end of the claw G13, the claw G13 rotates counterclockwise around the pin shaft G121 so that the claw G13 can be located above the fermentation sieve 200. Under the action of gravity, the lower end of the claw G13 drops clockwise to grasp the fermentation sieve 200; when the pulling cylinder G11 retracts the pulling seat G12 to reset, the fermentation sieve 200 moves with the claw G13, thereby realizing the extraction of the fermentation sieve 200 from the sliding chamber D111. Among them, the blocking plate G122 prevents the claw G13 from rotating excessively clockwise.

[0098] In some specific embodiments, to improve the pickling effect, the pickling device further includes a closing mechanism E0, and the closing mechanism E0 is located above the conveying path of the flipping and discharging mechanism D0; referring to Figure 19 and 20 , the closing mechanism E0 includes a base plate E10, a plurality of closing plates E20, and a seventh driver E30; the base plate E10 is arranged to be liftable, the closing plates E20 are movably arranged on the base plate E10, and the plurality of closing plates E20 surround the outside of the plurality of tofu embryo blocks; the seventh driver E30 is used to drive the closing plates E20 to move; in other words, when the flipping and discharging mechanism D0 moves below the closing mechanism E0, the closing mechanism E0 corresponds to the tofu embryo blocks on the top plate D30, the base plate E10 descends to approach the tofu embryo blocks, such that the plurality of closing plates E20 surround the outside of the plurality of tofu embryo blocks. By driving the closing plates E20 to move through the seventh driver E30, the plurality of closing plates E20 push these tofu embryo blocks together, realizing the reduction or even elimination of the gaps between the tofu embryo blocks, thereby improving the subsequent salt-pickling effect; in addition, after the tofu embryo blocks on the top plate D30 are closed by the closing mechanism E0, they will move to a position docking with the transfer mechanism A0, and the closing mechanism E0 can also adjust the positions of the tofu embryo blocks on the top plate D30, such that the tofu embryo blocks can be more precisely adsorbed by the suction cups A10 of the transfer mechanism A0.

[0099] Generally, the tofu embryo blocks are square, and multiple tofu embryo blocks are arranged in an array on one layer. Refer to Figure 20 In this embodiment, the multiple closing plates E20 include two first closing plates E20a arranged in parallel and two second closing plates E20b arranged in parallel; the first closing plates E20a and the second closing plates E20b are perpendicularly arranged; in this way, the closing plates E20 can fit the outer lines of the multiple tofu embryo blocks, thus facilitating the pushing of the tofu embryo blocks.

[0100] Regarding this closing mechanism E0, to improve the stability of the movement of the closing plates E20 on the substrate E10, in this embodiment, a sliding connection is formed between the closing plates E20 and the substrate E10 through a guiding structure. Refer to ​ Specifically, guiding strips E11 are provided at the edges of the substrate E10, guiding holes E21 are formed on the closing plates E20, the shapes of the guiding strips E11 and the guiding holes E21 correspond to each other, and the guiding strips E11 are slidably inserted into the guiding holes E21. To facilitate the setting of the seventh driver E30, refer to ​ A base frame E40 is provided above the substrate E10, the substrate E10 and the base frame E40 are relatively fixed to each other, and an installation space E41 is formed therebetween. The seventh driver E30 is arranged in the installation space E41, that is, the seventh driver E30 is arranged above the substrate E10. Among them, the seventh driver E30 can be selected as a cylinder. To facilitate the movement of the substrate E10, refer to ​ The base frame E40 is driven to move up and down by a second electric push rod E50, and the substrate E10 and the base frame E40 move synchronously; the second electric push rod E50 is installed on a fixing plate E60, and the fixing plate E60 is fixed on the machine frame 100.

[0101] In some specific implementation manners, refer to ​ and ​ This pickling device further includes a third conveying mechanism H0 for conveying the pickling basin 300, and a limiting mechanism H10 for fixing the pickling basin 300 is provided on the third conveying mechanism H0. In this embodiment, the limiting mechanism H10 includes a limiting clamping member H11 and a ninth driver H12 for driving the limiting clamping member H11 to move up and down; among them, the ninth driver H12 uses a cylinder; when the pickling basin 300 is conveyed to the set position, the ninth driver H12 drives the limiting clamping member H11 to rise, so that the limiting clamping member H11 fixes the pickling basin 300, enabling the transfer mechanism A0 to accurately place the tofu embryo blocks into the pickling basin 300, and also enabling the salt sprinkling mechanism B0 to accurately sprinkle salt into the pickling basin 300.

[0102] In some specific embodiments, there are four turning and discharging mechanisms D0. The four turning and discharging mechanisms D0 achieve circumferential rotation through the conveying mechanism F0. Each turning and discharging mechanism D0 switches among four positions, which are, for the convenience of description, referred to as the first working position, the second working position, the third working position, and the fourth working position. Specifically, when the pickling equipment is actually working, workers place the fermentation sieve filled with tofu embryo blocks on the first conveying mechanism C20, and push the tofu embryo blocks through the embryo scraping mechanism C10 so that the tofu embryo blocks are not adhered to the fermentation sieve 200. Then the fermentation sieve 200 enters the turning and discharging mechanism D0 at the first working position to achieve turning, and the tofu embryo blocks are separated from the fermentation sieve 200. Through the rotation of the conveying mechanism F0, the turning and discharging mechanism D0 rotates from the first working position to the second working position, and the fermentation sieve in the turning and discharging mechanism D0 is taken out by the fermentation sieve recovery device G0. Then the turning and discharging mechanism D0 rotates from the second working position to the third working position, and the closing mechanism E0 at the third working position closes the tofu embryo blocks on the top plate D30. Then the turning and discharging mechanism D0 rotates from the third working position to the fourth working position, and the transfer mechanism A0 transfers the tofu embryo blocks at the fourth working position into the pickling basin 300. After the tofu embryo blocks in the pickling basin 300 reach a certain number of layers, the pickling basin is conveyed away through the third conveying mechanism H0. This pickling equipment can greatly reduce labor costs.

[0103] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
