Description

Technical Field

[0001] The present application relates to the field of microbial fermentation equipment, and in particular to a buckling assembly and a buckling machine that are beneficial for pulp extraction. Background Art

[0002] Qu blocks are fermentation strains made from wheat, corn and other grains. They are generally used in winemaking processes, but there are also qu blocks used for fermenting feed. Qu blocks used for feed fermentation can reduce or remove anti-nutritional factors such as non-starch polysaccharides, phytic acid, cellulose, hemicellulose and pectin substances in feed raw materials, reduce the occurrence of intestinal diseases and thus achieve better antibiotic replacement effects. Qu block slurry extraction refers to a thin water film-like substance similar to "juice" that appears on the surface of the qu block during or after the qu block pressing process. The slurry extraction effect is particularly important for qu block fermentation. If the slurry extraction effect is good, the qu block will retain water and be breathable, the microorganisms will ferment fully, and the target metabolites will be abundant. If the slurry extraction effect is poor, the qu block surface will dry and crack, and it will easily break and fall apart, the water will be lost quickly, the fermentation will be insufficient or abnormal, and the target metabolites will be few.

[0003] The existing buckling machine includes a machine body and a pressing plate mold. The machine body includes a workbench, a top plate and a power part. A horizontal surface is opened on the upper surface of the workbench, and the horizontal surface is used to place the curved block. The top plate is arranged above the workbench, and the power part is installed on the top plate. The power part is connected to the pressing plate mold. The pressing plate mold is located between the top plate and the workbench. The user can control the action of the power part to make the pressing plate mold move vertically back and forth above the workbench, so that the pressing plate mold can press down the curved block on the workbench to achieve the purpose of buckling and forming.

[0004] The above-mentioned related technical solutions have the following defects: after the pressing plate mold is pressed on the koji block, the koji block is easily adhered or adsorbed on the surface of the pressing plate mold, which causes the koji block to be chipped and cracked, and the surface of the koji block to be damaged, affecting the pulp extraction effect and subsequent fermentation. Utility Model Content

[0005] In order to reduce damage, cracking, corner chipping and adhesion on the surface of the curved block, and thereby improve the slurry extraction effect of the curved block, the present application provides a buckling assembly and a buckling machine that are conducive to slurry extraction.

[0006] The present application provides a buckling assembly that is beneficial for pulp extraction and adopts the following technical solution:

[0007] A buckling assembly that is beneficial for pulp extraction includes an upper pressure head and a lower pressure head arranged relatively to each other, and a buckling module located between the upper and lower pressure heads. The buckling module has a cylindrical structure. When the upper pressure head and the lower pressure head are pressed together, they are located in the middle area of ​​the buckling module and fit against the inner wall of the buckling module. The upper pressure head, the lower pressure head and the middle of the buckling module form a molding area. The lower surface of the upper pressure head, the upper surface of the lower pressure head and the inner peripheral wall of the buckling module are uneven and slightly rough surfaces, and a hydrophobic structure is formed on the surface.

[0008] By adopting the above technical solution, uneven micro-rough surfaces are formed on the surfaces of the upper pressure head, the lower pressure head and the buckling module. When the upper pressure head and the lower pressure head extrude the curved block, a small gap exists between the curved block and the pressure head, thereby reducing the probability of negative pressure adsorption between the curved block and the pressure head, allowing the curved block and the pressure head to be smoothly separated, reducing damage, cracking, and corner defects on the surface of the curved block, and thereby improving the slurry lifting effect of the curved block.

[0009] Optionally, the hydrophobic structures are grooves opened on the lower surface of the upper pressure head, the upper surface of the lower pressure head, and the inner wall of the buckling module. The grooves on the lower surface of the upper pressure head and the upper surface of the lower pressure head are distributed crisscross, and the grooves on the inner wall of the buckling module are all opened vertically.

[0010] By employing this technical solution, when the upper and lower pressing heads compress the koji block, numerous small gaps are formed between the block and the mold, preventing negative pressure adhesion. Furthermore, the contact surface between the material and the mold has a hydrophobic structure, adapting to the extrusion of materials with varying moisture contents. Most importantly, the pressed and formed surface is less susceptible to damage and chipping, maintaining a relatively intact block, which is beneficial for subsequent fermentation.

[0011] Optionally, the upper pressure head and the lower pressure head are both penetrated by a plurality of through holes, and the through holes are vertically opened and penetrate the upper pressure head and the lower pressure head.

[0012] By employing this technical solution, users can pressurize water or bacterial liquid into the through-holes. This water or bacterial liquid is distributed across the surface of the koji block through the crisscrossing grooves. This helps regulate the fermentation environment of the koji block, allowing for ventilation while retaining moisture within the block, stabilizing the fermentation process and preventing the block from drying out and cracking. Furthermore, the nutrients in the bacterial liquid (slurry) further promote the growth of beneficial microorganisms, and due to the space-occupying effect, the chance of contamination by other bacteria is reduced.

[0013] Optionally, the through holes are all located at the intersection of the grooves on the upper pressure head and the lower pressure head.

[0014] By adopting the above technical solution, when slurry or bacterial liquid flows out of the through hole, the slurry or bacterial liquid can flow along the groove, so that any dry surface on the block can absorb the slurry or bacterial liquid, so that the overall moisture content of the block remains uniform.

[0015] Optionally, the through hole port located on the lower surface side of the upper pressure head and the through hole port located on the upper surface side of the lower pressure head are both tapered ports with gradually increasing inner radial ports.

[0016] By adopting the above technical solution, when the upper pressure head and the lower pressure head abut against the curved block, the contact area between the through hole and the curved block is larger. When the water pump injects slurry or bacterial liquid into the pressure tube, the contact area between the surface of the curved block and the slurry or bacterial liquid is larger, which can absorb the slurry or bacterial liquid more evenly. At the same time, the tapered mouth helps to take the curved block more conveniently.

[0017] Optionally, each of the through holes is connected to a pressure pipe.

[0018] By adopting the above technical solution, when the upper pressure head and the lower pressure head are in contact with the block, the water pump injects water into the pressure pipe, so that the slurry or bacterial liquid can be dispersed on the block, thereby achieving the effect of adjusting the moisture content of the block. Users do not need to brush slurry on the surface of the block, thereby improving work efficiency.

[0019] The present application provides a buckling machine that is beneficial for pulp extraction and adopts the following technical solutions:

[0020] A buckling machine that is conducive to pulp extraction includes a buckling assembly that is conducive to pulp extraction, an upper power member that drives the upper pressure head to move, a lower power member that drives the lower pressure head to move, and a frame that supports the buckling assembly and the power member. A feeding part is provided on one side of the buckling assembly, and a material receiving platform is provided on the opposite side of the feeding part.

[0021] By adopting the above technical solution, by arranging a feeding part and a receiving table on both sides of the frame, the feeding part can continuously supply the raw materials required for manufacturing the curved blocks. After the upper and lower pressure heads extrude the curved blocks, the formed curved blocks can be moved to the receiving table, thereby improving the efficiency of users in taking the formed curved blocks from between the upper and lower pressure heads.

[0022] Optionally, the frame includes a base, the buckling module is fixed to an upper end of the base, and the frame further includes a vertically arranged guide column connected to the upper end of the buckling module, and a top plate connected above the guide column;

[0023] The upper power member is fixed to the top plate, the lower power member is fixed to the bottom of the base, and the upper pressure head is provided with a guide hole matched with the guide column.

[0024] By adopting the above technical solution, by setting a top plate above the frame and a base below the frame, the upper power part can be set on the top plate and drive the upper pressure head to press vertically downward, and the lower power part can drive the upper pressure head to move up and lift the curved block below the frame.

[0025] In summary, the beneficial technical effects of this application are:

[0026] 1. By machining the upper and lower rams and the buckling module to form uneven micro-rough surfaces, when the upper and lower rams squeeze the block, a small gap exists between the block and the rams, thereby reducing the negative pressure adhesion between the block and the ram, allowing the block and the ram to separate smoothly, reducing damage, cracking, and chipping on the block surface, thereby improving the block slurry extraction effect;

[0027] 2. The contact surface between the material and the mold has a hydrophobic structure, which can adapt to the extrusion of materials with different moisture contents. After pressing and molding, the surface is not easily damaged or chipped, and the integrity of the koji is good, which is conducive to the subsequent pulp extraction and fermentation.

[0028] 3. By pressurizing water or bacterial liquid into the through holes, the water or bacterial liquid is distributed on the surface of the koji block through the criss-cross grooves, which is beneficial to regulating the fermentation environment of the koji block. While allowing air to pass through, it also maintains the moisture inside the koji block, which is beneficial to the stability of the fermentation process and prevents the koji block from drying out. At the same time, the nutrients in the bacterial liquid (slurry) can better promote the growth of beneficial microorganisms, and due to the influence of the space effect, the chance of contamination by miscellaneous bacteria is reduced.

[0035] The present application is further described in detail below with reference to the accompanying drawings.

[0036] The embodiment of the present application discloses a buckling component that is beneficial to pulp extraction, referring to Figure 1 and Figure 2, including an upper pressure head 21, a lower pressure head 22 and a buckling module 23. The buckling module 23 is set to a rectangular frame structure. The upper pressure head 21 and the lower pressure head 22 are both set horizontally. The upper pressure head 21 is set above the lower pressure head 22. The upper pressure head 21 and the lower pressure head 22 move back and forth at intervals in the vertical direction. The buckling module 23 is used to place the bending block. The upper pressure head 21 falls vertically and falls into the buckling module 23. The lower pressure head 22 is set below the buckling module 23 and moves vertically upward. When the upper pressure head 21 and the lower pressure head 22 are pressed together, they are located inside the buckling module 23.

[0037] Reference Figure 2 and Figure 3 The lower surface of the upper pressure head 21, the upper surface of the lower pressure head 22, and the inner peripheral wall of the buckling module 23 are uneven micro-rough surfaces, which are formed by hammering. The upper pressure head 21, the lower pressure head 22, and the buckling module 23 have uneven spots on their surfaces. Grooves are provided on the lower surface of the upper pressure head 21 and the upper surface of the lower pressure head 22, and the grooves are distributed in a field shape. Grooves are provided on the inner wall of the buckling module 23, and the grooves on the buckling module 23 are provided vertically. When the upper pressure head 21 and the lower pressure head 22 squeeze the koji block, the moisture in the koji block is squeezed to the surface of the koji block. At this time, the liquid water on the surface of the koji block can flow along the grooves, so that the moisture in the koji block is evenly distributed on the entire koji block, which can make the microorganisms in the koji block ferment evenly and improve the fermentation effect.

[0038] Reference Figure 3 and Figure 4 , a plurality of through holes 20 are provided on the upper pressure head 21 and the lower pressure head 22, and the through holes 20 are provided at intervals along the length direction and width direction of the upper pressure head 21 and the lower pressure head 22. The through holes 20 are vertically provided and pass through the upper pressure head 21 and the lower pressure head 22. A plurality of pressure pipes 24 are connected to the upper pressure head 21 and the lower pressure head 22, and one pressure pipe 24 is connected to one through hole 20. The pressure pipe 24 uses a hose, and the pressure pipe 24 is connected to a water pump. The water pump injects slurry or bacterial liquid into the pressure pipe 24, so that the slurry or bacterial liquid flows out from the through hole 20. When the upper pressure head 21 and the lower pressure head 22 are in contact with the curved block, the water pump injects water into the pressure pipe 24, so that the slurry or bacterial liquid can flow to the curved block, thereby achieving the effect of adjusting the moisture content of the curved block. The user does not need to brush the slurry on the surface of the curved block, thereby improving work efficiency. In other embodiments, the pressure tube 24 may be connected to an air pump, which injects air into the pressure tube 24 to allow the air to flow out of the through hole 20 , thereby reducing the probability of the residue of the curved block clogging the through hole 20 .

[0039] Reference Figure 3The through hole 20 port on the lower surface side of the upper pressure head 21 and the through hole 20 port located on the upper surface side of the lower pressure head 22 are both tapered ports with gradually increasing inner radial ports. When the upper pressure head 21 and the lower pressure head 22 are in contact with the curved block, the contact surface between the through hole 20 and the curved block is larger. When the water pump injects a large amount of slurry or bacterial liquid into the pressure pipe 24, the contact surface between the curved block surface and the slurry or bacterial liquid is larger, which can absorb the slurry or bacterial liquid faster, making it easier for users to control the moisture content of larger curved block products.

[0040] The embodiment of the present application discloses a buckling machine that is beneficial to pulp extraction, referring to Figure 1 and Figure 5 , including a body 1, a buckling assembly, an upper power member 141 for driving the upper pressing head 21 to move, and a lower power member 142 for driving the lower pressing head 22 to move. The body 1 includes a feeding part 10, a frame 11 and a material receiving platform 12. The frame 11 and the material receiving platform 12 are connected flush with each other. The upper power member 141 and the lower power member 142 are both connected to the frame 11. Hydraulic cylinders can be used for the upper power member 141 and the lower power member 142. The frame 11 includes a base 110, a workbench 111, a top plate 112 and a guide column 113. The base 110 is arranged below the workbench 111, the top plate 112 is arranged above the workbench 111, and the guide column 113 is vertically connected between the top plate 112 and the workbench 111. The workbench 111 is flush with the material receiving platform 12. The lower power member 142 is vertically mounted on the base 110 , the upper end of the lower power member 142 is connected to the lower pressure head 22 , and the upper power member 141 is vertically mounted on the top plate 112 .

[0041] Reference Figure 1 The workbench 111 is provided with a through hole, and the lower pressure head 22 is arranged in the through hole. The lower power member 142 can drive the lower pressure head 22 to rise from the through hole. The feeding part 10 is a funnel structure, and the feeding part 10 is arranged higher than the workbench 111. The workbench 111 is slidably connected to the storage bin 3, and the storage bin 3 can slide below the feeding part 10. At this time, the material can be poured into the storage bin 3 through the feeding part 10. The buckling module 23 is connected to the outer wall of the bottom of the storage bin 3. The bottom of the storage bin 3 is provided with an opening. The material in the storage bin 3 can be poured into the buckling module 23. At this time, the upper pressure head 21 and the lower pressure head 22 can squeeze the material in the buckling module 23.

[0042] Reference Figure 1 and Figure 5When in use, the storage bin 3 first slides to the bottom of the feeding part 10, then the storage bin 3 moves horizontally to between the upper pressure head 21 and the lower pressure head 22. At this time, the upper pressure head 21 falls and the lower pressure head 22 moves upward. The material is compacted in the buckling module 23. Then the upper pressure head 21 moves upward and the lower pressure head 22 falls with the curved block, and the storage bin 3 can slide back to the bottom of the feeding part 10. At this time, the lower pressure head 22 moves upward, causing the curved block to be removed from the through hole of the workbench 111. After the storage bin 3 is loaded with material, it continues to move, and the buckling module 23 can push the curved block horizontally onto the receiving platform 12.

[0043] The implementation principle of the embodiment of the present application is: by opening grooves on the upper pressure head 21 and the lower pressure head 22, the grooves are connected to each other. When the upper pressure head 21 and the lower pressure head 22 squeeze the block, the water in the block is squeezed out and adheres to the surface of the block, completing the block slurry extraction operation. The water in the block can flow along the grooves, so that the water is evenly distributed on the surface of the block. By opening a through hole 20 on the upper pressure head 21 and the lower pressure head 22, a pressure pipe 24 is set in the through hole 20, so that the pressure pipe 24 can input slurry or bacterial liquid into the through hole 20. When the pressing plate mold 2 presses down the block, the slurry or bacterial liquid flows out from the through hole 20, thereby achieving the effect of adjusting the moisture content of the block.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
