Description

Technical Field

[0001] The invention belongs to the technical field of bean product processing, in particular to a preparation device for bean product production. Background Art

[0002] Qianzhang is a kind of food, also known as dried tofu or white leaves. It is a thin sheet of dried tofu as thin as paper, yellow and white in color, and can be eaten cold, stir-fried, or boiled. In the preparation process of Qianzhang, a layer of gauze is usually placed in the mold to ensure that it is flat and without wrinkles. Then the tofu brain is broken up and poured onto the gauze, and it is scraped flat to ensure uniformity. Then, it is not covered with a layer of gauze and compacted with a preparation device to remove excess moisture. After waiting for a certain period of time, the Qianzhang is collected to complete the production.

[0003] A patent with publication number CN117284782B discloses a sheet processing device. The movable frame of the patent is reciprocatingly slidable, which can drive the receiving plate to reciprocate. During the reciprocating movement of the receiving plate, the sheets conveyed by the conveying device will be folded on the receiving plate. The conveying speed of the conveying device is the same as the sliding speed of the movable frame, which can well realize the stacking of the sheets on the receiving plate. The rotating roller is rotatably arranged at a position close to the receiving plate. Before the sheets fall onto the receiving plate, they first pass through two rotating rollers. The rotating rollers are actively rotated, and the rotating speed is the same as the conveying speed of the sheets. The two rotating rollers clamp The thousand sheets play a guiding role for the thousand sheets. Because the rotating roller is closer to the receiving plate, the thousand sheets will be folded onto the receiving plate under the constraint of the rotating roller. The thousand sheets are more controllable when bending, which improves the regularity of folding and makes the overall smoother. The diameter of the rotating roller is small, much smaller than the diameter of the output end of the conveying device, which is conducive to the bending of the thousand sheets. Under the action of the lifting device, the receiving plate slides in one direction once and will drop a certain distance. The dropped distance is generally the thickness of the thousand sheets. In this way, the distance from the rotating roller to the top of the receiving plate is constant, so the shape of the thousand sheets will be more regular and definite, and the overall smoother.

[0004] There are still some problems in the actual application of the above scheme. Usually, a layer of gauze is laid in the collection box, and then the tofu brain is discharged onto the gauze with a hose, and the tofu brain on the gauze is scraped flat to ensure the thickness and uniformity of the tofu brain. Then, a layer of gauze is laid on the scraped tofu brain again, and another layer of tofu brain is discharged. The operation is repeated many times in sequence to fill the entire collection box, and the tofu brain is pressurized by a pressing plate and a pressing device to discharge excess water and yellow slurry water inside the tofu brain, thereby completing the preparation of thousand sheets. However, this operation preparation method is not only cumbersome, but also it is difficult to ensure the uniformity of the distribution on the gauze when discharging the tofu brain with a water pipe, which results in the need to use a scraper to perform a second scraping operation on it, and too much tofu brain is discharged, and it needs to be scooped out, which makes it difficult to control the discharge amount and affects the preparation efficiency of thousand sheets.

[0021] 1. The preparation device for producing soy products described in the present invention drives a rotating column to drive a transmission pulley to rotate, and at the same time drives a belt to rotate, and then drives a driven pulley to rotate. During the rotation process, the driven pulley drives a tofu stirring and discharging component to stir and break up the tofu in the inner cavity of the tofu storage bucket, and at the same time scrapes the tofu at the bottom of the inner cavity of the tofu storage bucket to move, so that the tofu is discharged through the through hole onto a special gauze to prepare thousand sheets of embryos, thereby preventing the tofu from accumulating at the through hole, causing the through hole to be blocked, affecting the discharge efficiency and quantity of the tofu, and resulting in uneven thickness of the prepared thousand sheets of embryos, thereby solving the problem that when the preparation device for producing soy products is discharging tofu, it is difficult to break up the tofu, resulting in the block-shaped tofu easily blocking the discharge port, thereby affecting the discharge efficiency of the tofu, causing the tofu discharged on the gauze to be uneven, and resulting in uneven thickness of the prepared thousand sheets.

[0022] 2. The present invention relates to a preparation device for producing soy products. When the conveyor belt is used to drive the Qianzhang embryo to move, the tofu pudding on the conveyor belt is scraped and smoothed by a scraping component. When Qianzhang of different thicknesses needs to be prepared, the position of the mounting plate outside the rotating shaft is adjusted, so that the mounting plate is pressed against the torsion spring to increase the torsion force of the torsion spring. Then, the rotating shaft is twisted by the torsion spring to drive the rotating rod, and the rotating rod drives the scraper rod to approach the conveyor belt to adjust the distance, thereby scraping and smoothing the thickness and uniformity of the tofu pudding on the special gauze. This solves the problem that in the existing preparation device for producing soy products, after the tofu pudding is discharged onto the gauze, it is inconvenient to automatically scrape and smooth the tofu pudding, so that the operator scrapes the tofu pudding on the gauze by a scraper, which is not only cumbersome to operate but also affects the preparation efficiency of Qianzhang.

[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0041] Embodiment 1

[0042] like Figures 1 to 9 As shown, a bean product production device according to an embodiment of the present invention comprises a fixed frame 1 and a support frame 2 installed at the upper end of the fixed frame 1, and a conveyor belt 3 installed in the inner cavity of the support frame 2, and a tofu pudding stirring and discharging component 5 is installed on one side of the upper end of the support frame 2;

[0043] The tofu pudding stirring and discharging assembly 5 includes a second mounting frame 51 mounted on one side of the upper end of the support frame 2, a synchronous push rod 52 is arranged inside the upper end of the second mounting frame 51, and a bracket 53 is installed at the piston rod end of the synchronous push rod 52, a tofu pudding storage bucket 54 is installed between the brackets 53, and a plurality of through holes 57 are opened at the bottom of the inner cavity of the tofu pudding storage bucket 54 for uniformly and slowly discharging the tofu pudding to achieve the integrity of the forming of the thousand sheets;

[0044] A base 9 is fixedly connected to one side of the fixing frame 1, and a plurality of grooves 10 are provided on the upper end surface of the base 9, and a fixed slide post 11 is fixedly connected to the inner cavity of the plurality of grooves 10, and a thousand-sheet collecting assembly 8 is slidably connected to the outside of the fixed slide post 11;

[0045] The Qianzhang collection assembly 8 includes a Qianzhang filter press box 81 which is slidably connected in the inner cavity of the groove 10, and the bottom of the Qianzhang filter press box 81 is clamped on the outside of the fixed sliding column 11, which is used to drive the Qianzhang filter press box 81 to circulate and slide outside the fixed sliding column 11 to receive the Qianzhang folded collection. The inner cavity of the Qianzhang filter press box 81 is slidably connected with a filter mesh plate 82, which is used to filter the yellow slurry water inside the tofu brain.

[0046] Specifically, in the prior art, the tofu pudding in the storage tank is broken up by using a stirring stick, and then the broken up tofu pudding is discharged onto the gauze by using a water pipe, and the tofu pudding on the gauze is scraped flat by using a scraper to ensure uniform thickness, and then a layer of gauze is spread on the scraped tofu pudding again, and another layer of tofu pudding is discharged, and the scraper is used to perform the scraping operation again, and after repeated reciprocation for several times, it is transferred to the filter press box, and the tofu pudding is pressed by using a pressing plate in combination with a pressing device to discharge the excess water and yellow pulp water inside the tofu pudding, thereby completing the preparation of the thousand sheets. However, this operation and preparation method is not only cumbersome, but also it is difficult to ensure the uniformity of the tofu pudding on the gauze by discharging the tofu pudding by using a water pipe, resulting in the need for a second scraping operation using a scraper, and the excessive discharge of tofu pudding exceeds the size of the gauze, resulting in the problem of waste of tofu pudding;

[0047] The present invention puts tofu into a tofu storage bucket 54, and simultaneously starts a synchronous push rod 52 to drive a bracket 53 to move downward, and enables the bracket 53 to drive the tofu storage bucket 54 to approach the conveyor belt 3 to adjust the spacing, so that the tofu is discharged evenly and slowly onto the conveyor belt 3 through a plurality of through holes 57. When discharging the tofu, gauze or special cloth is laid on the conveyor belt 3 in advance, and then the tofu is discharged through the plurality of through holes 57 so that it can be evenly laid on the gauze or special cloth to form thousand sheets of embryos. At the same time, the gauze or special cloth is driven to move by the conveyor belt 3, and then the thousand sheets of embryos are driven to move synchronously, and the thousand sheets of embryos are received by the thousand sheets of filter press box 81. During the process, the thousand sheets filter press box 81 is driven to slide back and forth outside the fixed sliding column 11, so that the thousand sheets embryos are laid on the filter mesh plate 82 in a folded manner. When the thousand sheets embryos are folded and laid on the filter mesh plate 82, the filter mesh plate 82 will move downward under the weight of the thousand sheets embryos to facilitate receiving the next thousand sheets embryos. After the thousand sheets filter press box 81 is used to reciprocate to receive multiple layers of thousand sheets embryos, the thousand sheets filter press box 81 is disassembled, and the pressing plate is placed in the inner cavity of the thousand sheets filter press box 81, and it is moved to the bottom of the extrusion equipment. The pressing plate is pushed by the extrusion equipment to press the thousand sheets embryos in the inner cavity of the thousand sheets filter press box 81 to discharge excess water and yellow slurry water inside, thereby completing the preparation of the thousand sheets and solving the above-mentioned problem.

[0048] like Figure 1 , Figure 2 , Figure 7 and Fig. 9 As shown, a yarn release assembly 4 is installed on one side of the upper end of the support frame 2, and the yarn release assembly 4 includes a first mounting frame 41 installed on one side of the upper end of the support frame 2, a servo motor 17 is installed inside the upper end of the first mounting frame 41, and a rotating column 43 is fixedly connected to the output shaft end of the servo motor 17, the rotating column 43 is located at one end of the first mounting frame 41 and is fixedly connected to a transmission pulley 42 on the outside, and the transmission pulley 42 is connected to a belt 23 for external transmission, a groove 19 is opened on one side of the first mounting frame 41, a limiting column 21 is fixedly connected to the inner cavity of the groove 19, a slider 20 is slidably connected to the outside of the limiting column 21, one end of the slider 20 is rotatably connected to the limiting roller 22, a first spring 24 is fixedly connected to the upper end surface of the slider 20, and one end of the first spring 24 is fixedly connected to the upper wall of the groove 19.

[0049] Specifically, when preparing thousand sheets, the special gauze 18 is installed on the outside of the rotating column 43, and the servo motor 17 is started to drive the rotating column 43 to rotate, and then the special gauze 18 is discharged. Then the operator pulls the special gauze 18 through the limit roller 22 and the conveyor belt 3, and places it on the surface of the conveyor belt 3. At the same time, the first spring 24 is used to bounce the slider 20 downward, and the slider 20 slides on the outside of the limit column 21, so that the slider 20 drives the limit roller 22 to move synchronously, thereby ensuring the smooth transportation of the special gauze 18. At the same time, during the rotation of the conveyor belt 3, the special gauze 18 is driven to move synchronously, and then the tofu pudding stirring and discharging component 5 is used to evenly discharge the tofu pudding on the special gauze 18, thereby realizing the automatic discharge of the tofu pudding and the special gauze 18, and improving the preparation efficiency of thousand sheets.

[0050] like Figure 2 , Figure 3 and Figure 8 As shown, a screw rod 55 is rotatably connected to the inner cavity of the tofu pudding storage bucket 54, and a scraping and stirring frame 56 is threadedly connected to the outer surface of the screw rod 55. Both sides of the scraping and stirring frame 56 are arranged in a triangular shape for cutting and breaking the tofu pudding. One end of the screw rod 55 passes through the tofu pudding storage bucket 54 and is fixedly connected to a driven pulley 58. The outer side of the driven pulley 58 is connected to the belt 23 for transmission.

[0051] Specifically, when preparing the thousand sheets, the servo motor 17 is started to drive the rotating column 43 to rotate, and the rotating column 43 drives the driving pulley 42 to rotate, and at the same time drives the belt 23 to rotate, and then drives the driven pulley 58 to rotate. During the rotation process, the driven pulley 58 will drive the screw rod 55 to rotate, and the screw rod 55 thread-driven scraping and stirring frame 56 to slide back and forth in the inner cavity of the tofu storage bucket 54, and the scraping and stirring frame 56 is arranged in a triangular shape on both sides, and then the scraping and stirring frame 56 stirs and breaks the tofu in the inner cavity of the tofu storage bucket 54, and at the same time scrapes the tofu storage The tofu pudding at the bottom of the inner cavity of the storage bucket 54 is moved so that the tofu pudding is discharged through the through hole 57 at the bottom of the inner cavity of the tofu pudding storage bucket 54, thereby preventing the tofu pudding from accumulating at the through hole 57 and causing the through hole 57 to be blocked, thereby affecting the discharge efficiency of the tofu pudding and the amount of the tofu pudding discharged onto the special gauze 18. This solves the problem that when the preparation device for soy product production is discharging tofu pudding, it is difficult to break up the tofu pudding, resulting in the block-shaped tofu pudding easily clogging the discharge port, thereby affecting the discharge efficiency of the tofu pudding, causing the tofu pudding discharged on the gauze to be uneven, resulting in uneven thickness of the prepared thousand sheets.

[0052] like Figure 2 , Figure 7 and Figure 8 As shown, a cross slot 44 is provided inside the rotating column 43, and a bidirectional threaded rod 48 is rotatably connected to the inner cavity of the cross slot 44. Two H-type sliding plates 45 are threadedly connected to the outer cavity of the bidirectional threaded rod 48, and a push rod 46 is rotatably connected to the inner cavity of the two H-type sliding plates 45. A splint 47 is rotatably connected to one end of the push rod 46. A special gauze 18 is installed on the outside of the rotating column 43, and the splint 47 is used to expand, squeeze and fix the special gauze 18, so as to realize the rapid installation and disassembly of the special gauze 18.

[0053] Specifically, before preparing the thousand sheets, the special gauze 18 is slidably installed on the outside of the rotating column 43, and the bidirectional threaded rod 48 is twisted to rotate, so that the bidirectional threaded rod 48 is threaded to drive the two H-shaped sliding plates 45 to move away from each other, and at the same time, the two H-shaped sliding plates 45 drive the pushing rod 46 to move synchronously, and then push the clamping plate 47 to slide out of the inner cavity of the cross slide 44, so as to expand, squeeze and fix the special gauze 18, and then start the servo motor 17 to drive the rotating column 43 to rotate, and then discharge the special gauze 18, and then the operator pulls the special gauze 18 through the limiting roller 22 It is placed between the conveyor belt 3 and fitly on the surface of the conveyor belt 3. At the same time, the first spring 24 is used to bounce the slider 20 and move it downward, and the slider 20 slides outside the limiting column 21, so that the slider 20 drives the limiting roller 22 to move synchronously, thereby ensuring the smooth transportation of the special gauze 18. At the same time, during the rotation of the conveyor belt 3, the special gauze 18 is driven to move synchronously, and then the tofu pudding stirring and discharging component 5 is cooperated to evenly discharge the tofu pudding on the special gauze 18, thereby realizing the automatic discharge of the tofu pudding and the special gauze 18, and improving the preparation efficiency of the thousand sheets.

[0054] like Figure 1 , Figure 2 , Figure 4 and Figure 8 As shown, a scraping component 6 is provided on one side of the inner cavity of the second mounting frame 51, and the scraping component 6 includes two mounting tubes 61 installed at the front and rear ends of the second mounting frame 51, and the inner cavities of the two mounting tubes 61 are rotatably connected with a rotating shaft 62, and one end of the rotating shaft 62 passes through the second mounting frame 51 and is fixedly connected to a rotating rod 65, and a scraping rod 66 is installed between the rotating rods 65, and the lower end of the scraping rod 66 is arranged in a semicircular arc shape, which is used to scrape and smooth the thickness and uniformity of the tofu pudding on the special gauze 18, so as to achieve the uniformity of the thickness of the later thousand sheets of forming.

[0055] like Figure 1 , Figure 2 , Figure 4 and Figure 8 As shown, a mounting plate 63 is installed outside the rotating shaft 62, and a torsion spring 64 is installed on one end face of the mounting plate 63. One end of the torsion spring 64 is fixedly connected to the inner wall of the mounting tube 61, and the mounting plate 63 can be adjusted at the position outside the rotating shaft 62, and is used to adjust the torsion of the torsion spring 64 according to the thickness of the prepared thousand sheets, so that the torsion spring 64 twists the rotating rod 65 to drive the distance between the scraper rod 66 and the conveyor belt 3, so as to achieve the thickness and uniformity of the tofu pudding on the special gauze 18 by scraping and smoothing.

[0056] Specifically, when the conveyor belt 3 is used to drive the special gauze 18 and the tofu pudding to move, the torsion spring 64 is used to twist the mounting plate 63 to rotate, and the mounting plate 63 drives the rotating shaft 62 to rotate, and then drives the rotating rod 65 to rotate, and at the same time, the rotating rod 65 drives the scraper rod 66 to rotate close to the conveyor belt 3, and the lower end of the scraper rod 66 is arranged in a semicircular arc shape, and then the scraper rod 66 is used to scrape and smooth the tofu pudding on the conveyor belt 3. When it is necessary to prepare the thousand sheets according to different thicknesses, the position of the mounting plate 63 outside the rotating shaft 62 is adjusted, so that the mounting plate 63 can be adjusted to the position of the mounting plate 63 outside the rotating shaft 62. The disk 63 presses against the torsion spring 64 to increase the torsion force of the torsion spring 64, and then the torsion spring 64 is used to twist the rotating shaft 62 to drive the rotating rod 65, and the rotating rod 65 drives the scraper rod 66 to approach the conveyor belt 3 to adjust the spacing, thereby scraping and smoothing the thickness and uniformity of the tofu pudding on the special gauze 18, which solves the problem that the existing preparation device for soy product production is inconvenient to automatically scrape and smooth the tofu pudding after discharging it on the gauze, resulting in the operator scraping the tofu pudding on the gauze with a scraper, which is not only cumbersome to operate, but also affects the preparation efficiency of the thousand sheets.

The cross mounting cylinder 78 is fixedly installed on the thousand-sheet filter press box 81, and a clamping bead is arranged on the outside of the telescopic rod 76, and the clamping bead is clamped with the rotating cylinder 77, which is used to adjust the length of the telescopic rod 76 according to the size of the thousand sheets folded in the inner cavity of the thousand-sheet filter press box 81.

[0060] The chain 72 is driven by the conveyor belt 3 to rotate, and the chain 73 is driven by the conveyor belt 3 to rotate. When the chain 73 rotates in a circular shape, it will drive the T-shaped mounting block 74 to move synchronously. At the same time, the T-shaped mounting block 74 drives the rotating sleeve 75 to move, and pulls the telescopic rod 76 to move synchronously, thereby driving the rotating cylinder 77 to move. A ball joint is fixed to one end of the rotating cylinder 77, and the ball joint is rotatably engaged with the cross mounting cylinder 78. The cross mounting cylinder 78 is installed with the thousand-sheet filter press box 81, so that when the T-shaped mounting block 74 rotates in a circular shape with the chain 73, the telescopic rod 76 can be used to pull the rotating cylinder 77 to drive the thousand-sheet filter press box 81 to slide back and forth outside the fixed sliding column 11, so that the thousand-sheet filter press box 81 receives the thousand-sheet embryos conveyed by the conveyor belt 3. As the thousand sheets filter press box 81 slides back and forth, the thousand sheets embryos are folded and collected. When it is necessary to adjust the size of the thousand sheets folded in the inner cavity of the thousand sheets filter press box 81, the position of the telescopic rod 76 inside it is adjusted by pulling the rotating cylinder 77. A card bead is provided on the outside of the telescopic rod 76, and the card bead is engaged with the rotating cylinder 77, so as to adjust the reciprocating sliding spacing of the thousand sheets filter press box 81, thereby achieving the effect of adjusting the folding size of the thousand sheets. This solves the problem that the existing preparation device for soy product production usually uses an electric push rod alone to drive the thousand sheets collection box to slide back and forth at the tail end of the conveyor belt, so as to receive the thousand sheets embryos conveyed by the conveyor belt for folding and collection. This not only increases the cost of the equipment, but also uses an electric push rod alone to drive the thousand sheets collection box to slide back and forth, which makes it difficult to control the integrity of the folding size of the received thousand sheets. It is also easy to increase the friction between the thousand sheets and the collection box, causing the thousand sheets to be torn, damaged and other problems.

[0061] like Figure 1 , Figure 5 and Fig. 9 As shown, the bottom of the inner cavity of the Qianzhang filter press box 81 is fixedly connected with T-shaped fixing rods 83 at the four corners, the outside of the T-shaped fixing rod 83 is slidably connected with a storage cylinder 84, and the upper end of the storage cylinder 84 is fixedly connected to the filter screen plate 82, and the upper wall of the inner cavity of the storage cylinder 84 is fixedly connected with a second spring 85, and one end of the second spring 85 is fixedly connected to the T-shaped fixing rod 83. Two drain outlets 86 are provided on the inner wall of the Qianzhang filter press box 81, and the inner cavities of the two drain outlets 86 are fixedly connected with a foldable telescopic tube 87, which is used to discharge and recover the yellow slurry water collected in the inner cavity of the Qianzhang filter press box 81.

[0062] Specifically, after the folding and collection of the thousand sheets of embryos is completed by using the thousand sheets of filter press box 81, the rotating cylinder 77 drives the ball joint and the cross mounting cylinder 78 to be removed and separated, and then the thousand sheets of filter press box 81 is pushed into the inner cavity of the limit frame 12, and the thousand sheets of filter press box 81 is abutted against the baffle 16, and the new thousand sheets of filter press box 81 is installed on the base 9, and the rotating cylinder 77 drives the ball joint and the cross mounting cylinder 78 to be plugged and installed, so as to receive the thousand sheets of embryos for folding, and the thousand sheets of filter press box 81 that slides into the inner cavity of the limit frame 12, then the electric push rod 14 is started to drive the pressing plate 15 to move downward, and at the same time, the pressing plate 15 drives the T-shaped sliding column 13 to slide inside the limit frame 12 to ensure that the pressing plate 15 moves downward smoothly, and then the pressing plate 15 slides into the inner cavity of the thousand sheets of filter press box 81, thereby The thousand sheets of embryos in the bean curd are pressed to squeeze out excess water and yellow pulp water inside the thousand sheets of embryos, and the squeezed excess water and yellow pulp water are discharged into the bottom of the inner cavity of the thousand sheets of filter press box 81 through the filter screen plate 82, and at the same time are discharged into the inner cavity of the foldable telescopic tube 87 through the drain port 86, and one end of the foldable telescopic tube 87 is connected to the external sewer, so as to directly discharge the excess water and yellow pulp water squeezed out of the thousand sheets of embryos, and avoid the excess water and yellow pulp water from being discharged into the factory and affecting the working environment of the factory, thereby solving the problem that when the existing preparation device for soy product production presses out the excess water and yellow pulp water inside the thousand sheets of embryos, the excess water and yellow pulp water cannot be collected and discharged into the sewer, resulting in the excess water and yellow pulp water being discharged into the factory, affecting the working environment of the factory for a long time and also breeding a large number of bacteria.

[0063] like Figure 1 and Fig. 9 As shown, a limit frame 12 is installed on one side of the front and rear ends of the base 9, and an electric push rod 14 is fixedly connected to the upper end surface of the limit frame 12. The piston rod end of the electric push rod 14 passes through the limit frame 12 and is fixedly connected to a pressing plate 15. T-shaped sliding columns 13 are installed at the four corners of the upper end surface of the pressing plate 15, and the T-shaped sliding columns 13 are slidably installed with the limit frame 12, and a baffle 16 is installed on one side of the limit frame 12.

[0064] Specifically, when the pressing plate 15 is used to press the thousand-sheet embryos in the inner cavity of the thousand-sheet filter press box 81, the thousand-sheet embryos will drive the filter mesh plate 82 to push the storage cylinder 84 to move downward. At the same time, the storage cylinder 84 squeezes the second spring 85 to slide downward on the outside of the T-shaped fixing rod 83, so that a certain space is always left at the bottom of the inner cavity of the thousand-sheet filter press box 81 for collecting excess water and yellow slurry water pressed out from the thousand-sheet embryos, thereby improving the convenience and cleanliness of recovering excess water and yellow slurry water inside the thousand-sheet embryos.

[0065] Working principle: before preparing the thousand sheets, the special gauze 18 is slidably installed on the outside of the rotating column 43, and the bidirectional threaded rod 48 is twisted to rotate, so that the bidirectional threaded rod 48 threadedly drives the two H-type sliding plates 45 to move away from each other, and at the same time, the two H-type sliding plates 45 drive the pushing rods 46 to move synchronously, and then push the clamping plate 47 to slide out of the inner cavity of the cross slide 44, so as to expand, squeeze and fix the special gauze 18, and then start the servo motor 17 to drive the rotating column 43 to rotate, and then discharge the special gauze 18, and then the operator pulls the special gauze 18 through between the limiting roller 22 and the conveyor belt 3, and puts it on the surface of the conveyor belt 3, and at the same time, uses the first spring 24 to bounce the slider 20 downward, and makes the slider 20 slide outside the limiting column 21, so that the slider 20 drives the limiting roller 22 to move synchronously, so as to ensure the stability of the special gauze 18 transportation, and at the same time, during the rotation of the conveyor belt 3, it drives the special gauze 18 to move synchronously;

[0066] Then, the servo motor 17 is started to drive the rotating column 43 to rotate, and the rotating column 43 drives the driving pulley 42 to rotate, and at the same time drives the belt 23 to rotate, and then drives the driven pulley 58 to rotate. During the rotation process, the driven pulley 58 will drive the screw rod 55 to rotate, and the screw rod 55 threadedly drives the scraping and stirring frame 56 to slide back and forth in the inner cavity of the tofu storage bucket 54, and the scraping and stirring frame 56 is arranged in a triangular shape on both sides, and then the scraping and stirring frame 56 stirs and breaks up the tofu in the inner cavity of the tofu storage bucket 54, and at the same time, scrapes the tofu at the bottom of the inner cavity of the tofu storage bucket 54 to move it, so that the tofu is discharged through the through hole 57 at the bottom of the inner cavity of the tofu storage bucket 54, so as to prevent the tofu from accumulating at the through hole 57, causing the through hole 57 to be blocked, affecting the discharge efficiency of the tofu, and affecting the amount of tofu discharged to the special gauze 18;

[0067] When the conveyor belt 3 is used to transport the special gauze 18 and tofu pudding, the conveyor belt 3 drives the driven roller 71 to rotate, and then drives the sprocket 72 to rotate. During the rotation of the sprocket 72, it will drive the chain belt 73 to rotate. When the chain belt 73 rotates in a ring shape, it will drive the T-shaped mounting block 74 to move synchronously. At the same time, the T-shaped mounting block 74 drives the rotating sleeve 75 to move, and pulls the telescopic rod 76 to move synchronously, and then drives the rotating cylinder 77 to move. A ball joint is fixed at one end of the rotating cylinder 77, and the ball joint is rotatably connected to the cross mounting cylinder 78. The cross mounting cylinder 78 is installed with the thousand-piece filter press box 81, so that the T-shaped mounting block 74 rotates in a ring shape with the chain belt 73 When the filter press box 81 is moved back and forth on the outside of the fixed slide column 11, the telescopic rod 76 can be used to pull the rotating cylinder 77 to drive the filter press box 81 to slide back and forth, so that the filter press box 81 can receive the embryos of the thousand sheets delivered by the conveyor belt 3. At the same time, the embryos of the thousand sheets are driven to fold and collect as the filter press box 81 slides back and forth. When it is necessary to adjust the size of the folded sheets in the inner cavity of the filter press box 81, the position of the telescopic rod 76 inside it is adjusted by pulling the rotating cylinder 77. A card bead is provided on the outside of the telescopic rod 76, and the card bead is engaged with the rotating cylinder 77, so as to adjust the reciprocating sliding distance of the filter press box 81, thereby achieving the effect of adjusting the folding size of the thousand sheets.

[0068] After the folding and collection of the thousand sheets of embryos are completed by using the thousand sheets filter press box 81, the rotating cylinder 77 drives the ball joint and the cross mounting cylinder 78 to be removed and separated, and then the thousand sheets of filter press box 81 is pushed into the inner cavity of the limit frame 12, and the thousand sheets of filter press box 81 is abutted against the baffle 16, and at the same time, a new thousand sheets of filter press box 81 is installed on the base 9, and the rotating cylinder 77 drives the ball joint and the cross mounting cylinder 78 to be plugged and installed, so as to receive the thousand sheets of embryos for folding, and the thousand sheets of filter press box 81 that slides into the inner cavity of the limit frame 12 drives the pressing plate 15 to move downward by starting the electric push rod 14, and at the same time, the pressing plate 15 drives the T-shaped sliding column 13 to slide in the limit Inside the frame 12, ensure that the pressing plate 15 moves downward smoothly, and then make the pressing plate 15 slide into the inner cavity of the thousand sheets filter press box 81, and then press the thousand sheets embryos in the inner cavity of the thousand sheets filter press box 81, so as to press out the excess water and yellow slurry inside the thousand sheets embryos, and the squeezed excess water and yellow slurry are discharged into the bottom of the inner cavity of the thousand sheets filter press box 81 through the filter mesh plate 82, and at the same time, are discharged into the inner cavity of the foldable telescopic tube 87 through the drain port 86, and one end of the foldable telescopic tube 87 is connected to the external sewer, so as to directly discharge the excess water and yellow slurry squeezed out of the thousand sheets embryos, so as to prevent the excess water and yellow slurry from being discharged into the factory and affecting the working environment of the factory.
