Description

Technical Field

[0001] This utility model relates to the field of koji block forming technology, specifically to a device for biomimetic foot-feeding forming of brewing koji. Background Technology

[0002] In the field of winemaking, packaged Daqu is a key raw material for saccharification and fermentation. Its forming quality directly affects the flavor and quality of the subsequent wine. The uniformity of the density of the Daqu blocks and the distribution of internal materials are the core indicators that determine the fermentation effect. At present, the production of packaged Daqu in the industry is still mainly based on the traditional manual stepping method: During the operation, the operator needs to manually fill the raw materials for making Daqu into a fixed frame mold. By continuously piling up the material, the material slides down by its own weight, and at the same time, the Daqu blocks are squeezed and formed by stepping and pushing the material.

[0003] In this process, there is a clear sequence to manual treading. The area treaded first forms the "head," and the area treaded later forms the "tail." The accompanying squeezing and rolling actions can achieve a reasonable distribution of materials inside the koji block, which to a certain extent ensures the quality of the koji block under the traditional process. However, manual treading of koji has significant limitations: on the one hand, a single person can only complete the production of one koji block at a time, which is labor-intensive and has low production efficiency, making it difficult to adapt to the needs of large-scale brewing; on the other hand, the tightness of the koji block is greatly affected by the operator's weight, treading force, and skill level, resulting in significant differences in the quality of koji blocks in the same batch, which directly affects the stability of subsequent fermentation.

[0004] To address the drawbacks of manual koji making, some companies have introduced mechanical koji-making machines. However, these machines often employ a one-time direct pressing method. While this method improves efficiency, it cannot simulate the "head" and "tail" formation process and the squeezing and rolling motions of manual koji making. This can easily lead to a density imbalance in the formed koji blocks, with the edges being too tight and the center too loose. Furthermore, the lack of a clear "head" and "tail" structure results in a chaotic distribution of materials within the koji blocks. Ultimately, this leads to a significant difference in fermentation quality between mechanically made koji and traditionally manually made koji, making it difficult to meet the stringent quality requirements of high-end baijiu brewing. Utility Model Content

[0005] This utility model aims to provide a biomimetic foot-feeding device for brewing koji, in order to solve the problems of high labor intensity, low efficiency, large quality difference of koji blocks, inability of mechanical pressing to simulate manual foot-feeding and extrusion actions, easy imbalance of koji block density, and inferior fermentation quality compared to manual foot-feeding in the existing technology.

[0006] The embodiments of this utility model are implemented as follows: This utility model provides a device for biomimetic foot-feeding molding of brewing starter culture, which includes a pressing mechanism; The bottom of the pressing mechanism is provided with a reciprocating translational rolling actuation component. The top of the rolling actuation component is vertically connected to the bottom of the pressing mechanism. The bottom of the rolling actuation component is connected to a rolling die for rotational rolling. The bottom of the rolling die is provided with a frame mold. The rolling die reciprocates and rolls on the top surface of the frame mold. The aforementioned rolling actuator has a platform, which is vertically and vertically connected to the aforementioned pressing mechanism. The bottom of the platform is provided with a reciprocating rolling actuator, and the aforementioned rolling die is rotatably connected to the end of the aforementioned rolling actuator that is away from the aforementioned platform.

[0007] In use, the frame mold carrying the koji-making material is first transported to the forming station and positioned by the conveying mechanism. Then, the pressing mechanism is controlled to move the platform equipped with the rolling execution component and the rolling mold along a preset trajectory until the rolling mold contacts the material in the frame mold and applies a preset initial pressure. Next, the rolling execution component is activated, causing the rolling execution component to drive the rolling mold to rotate and translate within the frame mold at the speed and trajectory set by the process, continuously rolling and shaping the material to simulate the squeezing and rolling action of manual koji making, forming a koji block with a "head" and "tail" structure. During the rolling process, single or multiple rolling can be set according to process requirements. After the rolling is completed, the pressing mechanism is controlled to move the platform and the rolling mold upward and reset, so that the rolling mold is separated from the koji block. Finally, the frame mold carrying the formed koji block is transported to the next station by the conveying mechanism to complete the single koji block rolling forming operation.

[0008] The biomimetic foot-feeding forming device for brewing koji disclosed in this embodiment, due to the coordinated structure of the aforementioned pressing mechanism, the aforementioned rolling execution component, the aforementioned rolling mold, and the aforementioned frame mold, can precisely apply force to the aforementioned platform through the aforementioned pressing mechanism, and in conjunction with the aforementioned rolling execution component, drive the aforementioned rolling mold to rotate and translate simultaneously. This can fully simulate the squeezing and rolling actions of manual koji making, so that the koji blocks form a regular "head" and "tail" structure, solving the problems of the lack of "head" and "tail" and density imbalance in existing mechanical koji making. At the same time, the device replaces manual labor with mechanized operation, which greatly reduces labor intensity and improves production efficiency. Moreover, the rolling pressure, trajectory, and number of times can be controlled by preset parameters to avoid koji block quality fluctuations caused by differences in manual operation, ensuring the consistency of koji block tightness and material distribution within the same batch, while improving the fermentation quality of koji blocks. This adapts to the needs of large-scale baijiu brewing, thus making the biomimetic foot-feeding forming device for brewing koji have the beneficial effects of reducing labor intensity, improving production efficiency, uniform koji block quality, realizing the actions of manual koji making and squeezing, preventing koji block density imbalance, and improving fermentation quality.

This guarantees stable rotation speed of the rolling die, thereby achieving uniform and continuous rolling and shaping of the curved block, and improving the consistency of material distribution and tightness within the curved block. In addition, it avoids contamination or interference from materials during the rolling process, facilitating motor inspection and maintenance, and reducing equipment maintenance costs.

[0015] Optionally, the end of the rolling die near the frame die is a turtle-back shaped concave arc surface.

[0016] This configuration allows the rolling die and frame die to precisely mold the turtle-back shaped structure on the upper part of the shaped block, meeting the shape requirements of traditional processes.

[0018] With this design, the aforementioned perforated holes can reduce the overall weight of the mold while ensuring the structural strength of the mold to achieve stable rolling, thereby reducing the load on the translation and rotation drive mechanisms and improving the operational flexibility and energy efficiency of the mechanism. At the same time, the aforementioned perforated holes can reduce the contact area between the mold and the material during rolling, preventing the material from sticking together due to excessive contact with the mold, further ensuring the uniformity of the internal structure of the curved block and improving the molding quality.

[0019] Optionally: The pressing mechanism has a top plate, and a telescopic cylinder is fixed on the top surface of the top plate. The telescopic shaft of the telescopic cylinder passes through the top plate and is detachably and fixedly connected to the platform.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0033] Example See Figure 1 , Figure 2 and Figure 3 This embodiment proposes a device for biomimetic foot-feeding molding of brewing starter culture, which includes a pressing mechanism 1; The bottom of the pressing mechanism 1 is provided with a reciprocating translational rolling execution component 2. The top of the rolling execution component 2 is connected to the bottom of the pressing mechanism 1 in a liftable manner. The bottom of the rolling execution component 2 is connected with a rolling die 3 for rotating rolling. The bottom of the rolling die 3 is provided with a frame die 4. The rolling die 3 reciprocates and rolls on the top surface of the frame die 4. The rolling actuator 2 has a platform 5, which is vertically connected to the pressing mechanism 1. The bottom of the platform 5 is provided with a reciprocating rolling actuator 6, and the rolling die 3 is rotatably connected to the end of the rolling actuator 6 away from the platform 5.

[0034] In operation, the frame mold 4, carrying the koji-making material, is first transported to the forming station and positioned by the conveying mechanism. Then, the pressing mechanism 1 is controlled to move the platform 5, which is equipped with the rolling execution component 2 and the rolling mold 3, downward along a preset trajectory until the rolling mold 3 contacts the material in the frame mold 4 and applies a preset initial pressure. Next, the rolling execution component 2 is activated, causing the rolling execution component 6 to drive the rolling mold 3 to rotate and translate within the frame mold 4 at the speed and trajectory set by the process, continuously rolling and shaping the material to simulate the squeezing and rolling action of manual koji making, forming a koji block with a "head" and "tail" structure. During the rolling process, single or multiple rolling can be set according to process requirements. After the rolling is completed, the pressing mechanism 1 is controlled to move the platform 5 and the rolling mold 3 upward and reset, so that the rolling mold 3 is separated from the koji block. Finally, the frame mold 4 carrying the formed koji block is transported to the next station by the conveying mechanism to complete the single koji block rolling forming operation.

[0035] The biomimetic foot-feeding forming device for brewing koji disclosed in this embodiment features a collaborative structure of a pressing mechanism 1, a rolling execution component 2, a rolling mold 3, and a frame mold 4. The pressing mechanism 1 drives the platform 5 to apply precise force, while the rolling execution component 2 drives the rolling mold 3 to rotate and translate simultaneously. This fully simulates the squeezing and rolling actions of manual koji making, resulting in a regular "head" and "tail" structure for the koji blocks. This solves the problems of existing mechanical koji making lacking "head" and "tail" and having density imbalances. Simultaneously, the device replaces manual labor with mechanized operations, significantly reducing labor intensity and increasing production efficiency. Furthermore, the rolling pressure, trajectory, and number of cycles can be controlled by preset parameters to avoid koji block quality fluctuations caused by differences in manual operation, ensuring consistency in the tightness and material distribution of koji blocks within the same batch. This also improves the fermentation quality of the koji blocks, adapting to the needs of large-scale baijiu brewing. Therefore, this biomimetic foot-feeding forming device for brewing koji offers the beneficial effects of reduced labor intensity, increased production efficiency, uniform koji block quality, realization of manual foot-feeding and squeezing / rolling actions, reduced koji block density imbalance, and improved fermentation quality.

[0036] See Figure 1 , Figure 2 and Figure 3 The bottom surface of the platform 5 is fixedly equipped with several coaxial lead screw seats 7. The axis of the lead screw seats 7 is provided with a rotatable reciprocating shaft 8. The end of the rolling actuator 6 near the platform 5 can be adapted to the reciprocating shaft 8. In this way, the lead screw seats 7 can form a stable multi-point support for the reciprocating shaft 8, avoiding deformation or displacement of the reciprocating shaft 8 due to force during the translation of the rolling actuator 6, ensuring the accuracy of the translation trajectory of the rolling actuator 6, and thus ensuring the consistency of the rolling mold 3 in rolling and shaping the curved block.

[0037] The top surface of platform 5 is equipped with a translation drive motor 9. The translation drive motor 9 and the reciprocating shaft 8 are axially aligned. The output shaft of the translation drive motor 9 is fixed with a first pulley 10, and the end of the reciprocating shaft 8 near the translation drive motor 9 is fixed with a second pulley 11. A transmission belt (not shown in the figure) is connected between the first pulley 10 and the second pulley 11. The transmission belt has buffering and vibration absorption characteristics, which can effectively reduce the vibration transmitted from the translation drive motor 9 to the reciprocating shaft 8, avoid vibration causing the rolling actuator 6 to shift, and ensure the accuracy and consistency of the rolling die 3 in shaping the curved block. In addition, the transmission belt transmission structure is simple and easy to install and maintain, which facilitates stable control of the translation speed of the rolling actuator 6 and improves the rolling forming quality of the curved block.

[0038] See Figure 1 , Figure 2 and Figure 3 A mold rotation motor 12 is provided on the side of the rolling actuator 6 away from the rolling mold 3. The mold rotation motor 12 is fixed on the side of the rolling actuator 6 away from the rolling mold 3. The output shaft of the mold rotation motor 12 is connected to the rotation axis of the rolling mold 3. The close-range direct connection between the mold rotation motor 12 and the rolling mold 3 can reduce energy loss in the transmission path, ensure that the power of the mold rotation motor 12 is efficiently transmitted to the rolling mold 3, ensure the stable rotation speed of the rolling mold 3, and thus achieve uniform and continuous rolling and shaping of the curved block, improving the consistency of material distribution and tightness inside the curved block. In addition, it can also avoid the material from contaminating or interfering with the mold rotation motor 12 during the rolling process, facilitate the inspection and maintenance of the motor, and reduce equipment maintenance costs.

[0039] The end of the rolling die 3 near the frame die 4 is a turtle-back shaped concave arc surface 13. This allows the rolling die 3 to directly cooperate with the frame die 4 to accurately shape the turtle-back shaped structure on the upper part of the shaped block, which meets the shape requirements of traditional processes. At the same time, the turtle-back shaped concave arc surface 13 can make the material contact pressure more uniform during rolling, avoid local overpressure or loosening, ensure the consistent distribution and tightness of the material in the shaped block, and improve the fermentation quality.

[0040] See Figure 1 , Figure 2 and Figure 3 The rolling die 3 has a hollow hole 14 in the middle. The hollow hole 14 can reduce the overall weight of the die while ensuring the strength of the die structure to achieve stable rolling, reduce the load on the translation drive and rotation drive mechanism, and improve the operational flexibility and energy economy of the mechanism. At the same time, the hollow hole 14 can reduce the contact area between the die and the material during rolling, avoid the material from sticking due to excessive contact with the die, further ensure the uniformity of the internal structure of the curved block and improve the molding quality.

[0041] The pressing mechanism 1 has a top plate 15, and a telescopic cylinder 16 is fixed on the top surface of the top plate 15. The telescopic shaft of the telescopic cylinder 16 passes through the top plate 15 and is detachably bolted or hinged to the platform 5. This provides stable support for the telescopic cylinder 16 with the help of the top plate 15, ensuring the accuracy of the telescopic shaft driving the platform 5 to move up and down, and ensuring the stability of the pressure applied to the material by the rolling die 3. The detachable connection also facilitates the disassembly and maintenance of the platform 5 and the telescopic shaft, reducing the difficulty of equipment maintenance. At the same time, the driving method of the telescopic cylinder 16 can flexibly adjust the lifting speed and downward pressure of the platform 5 to adapt to the forming requirements of curved blocks under different processes, thus improving the applicability of the mechanism.

[0042] See Figure 1 , Figure 2 and Figure 3 Platform 5 has several guide rods 17 at both ends, which are vertically welded to the top surface of platform 5. The top plate 15 has several guide rings 18 that penetrate the top plate 15 at the positions corresponding to the guide rods 17. The guide rods 17 are movably fitted into the guide rings 18. Through the cooperation of the guide rods 17 and the guide rings 18, precise guidance is provided for the up and down movement of platform 5, avoiding misalignment of the rolling die 3 due to force deviation of platform 5, and ensuring the forming accuracy of the curved block. In addition, the welded and fixed guide rods 17 have a stable structure, which can enhance the load-bearing capacity of platform 5, while the movable fitting design reduces friction between components and improves the stability of the mechanism. At the same time, multiple sets of guide structures further optimize the force distribution, avoid local stress concentration, and extend the service life of the equipment.

[0043] The frame mold 4 is a movable part. The first pressing mold assembly 19 and the second pressing mold assembly 20 are respectively provided on both sides of the frame mold 4. The first pressing mold assembly 19 and the second pressing mold assembly 20 both have a fixed seat 21. A Z-shaped pressing member 22 is bolted to the fixed seat 21. One end of the Z-shaped pressing member 22 is bolted to the top of the fixed seat 21, and the other end of the Z-shaped pressing member 22 tightly abuts against the edge of the frame mold 4. In this way, the Z-shaped pressing member 22 can accurately limit the frame mold 4, prevent the frame mold 4 from shifting during rolling, and ensure the stability of the curved block forming position. At the same time, the bolted connection allows the Z-shaped pressing member 22 to be detachable and adjustable to adapt to the limiting requirements of different specifications of frame mold 4, thereby improving the versatility of the mechanism.

[0044] See Figure 1 , Figure 2 and Figure 3The output end of the translation drive motor 9 is connected to a reduction gearbox (not shown in the figure). The output end of the reduction gearbox is connected to one end of the reciprocating shaft 8. The end of the reciprocating shaft 8 away from the reduction gearbox is supported by the screw seat 7 and the platform 5. The reduction gearbox can accurately adjust the speed of the reciprocating shaft 8 to avoid the rolling actuator 6 from being unstable due to excessive speed, and to ensure the uniformity of the rolling of the curved block by the rolling die 3. In addition, the support of several screw seats 7 on the reciprocating shaft 8 can prevent it from deforming due to uneven force at both ends, and ensure the accuracy of the rotation and translation trajectory of the reciprocating shaft 8.

[0045] See Figure 1 , Figure 2 and Figure 3 In this embodiment, the translation drive motor 9 is externally connected to a power supply (not shown in the figure) and a controller (not shown in the figure). The power supply provides stable operating power to the translation drive motor 9 and can be matched with DC or AC power according to the motor power. The power supply circuit is equipped with an overload protection module (not shown in the figure), which can automatically cut off the power supply when the motor load is too large to prevent the motor from being damaged due to overload. The controller is connected to the translation drive motor 9 and can preset and adjust the start and stop timing, output speed and forward and reverse switching frequency of the motor, thereby accurately controlling the rotation speed and direction of the reciprocating shaft 8. This enables controllable adjustment of the translation speed, translation direction and translation stroke of the rolling actuator 6 driving the rolling mold 3 to adapt to the rolling forming process requirements of different specifications of curved blocks. At the same time, the controller (not shown in the figure) can be linked with the central control system (not shown in the figure) of the entire forming mechanism to ensure that the action of the translation drive motor 9 is coordinated with the action sequence of the pressing mechanism 1 and the mold rotation actuator 12, ensuring that the rolling forming process is carried out in an orderly and efficient manner.

[0046] See Figure 1 , Figure 2 and Figure 3 In this embodiment, the mold rotation actuator 12 is externally connected to a power supply (not shown in the figure) and a controller (not shown in the figure). The power supply provides the mold rotation actuator 12 with working power of appropriate power. It can select DC or AC power supply mode according to the rated voltage and power of the motor. In addition, the power supply circuit has an overcurrent protection element (not shown in the figure) and a voltage stabilization module (not shown in the figure) connected in series. This can prevent the motor from burning out due to excessive current and avoid voltage fluctuations that cause unstable motor speed, thus ensuring the continuity of the rotation of the rolling die 3.

[0047] See Figure 1 , Figure 2 and Figure 3In this embodiment, the telescopic cylinder 16 is connected to a hydraulic pump (not shown in the figure), which provides stable hydraulic power for the telescopic cylinder 16 to extend and retract. The hydraulic pump and the telescopic cylinder 16 are connected by a high-pressure hydraulic oil pipe (not shown in the figure), and the oil pipe is equipped with a pressure regulating valve (not shown in the figure) and a check valve (not shown in the figure). The pressure regulating valve can accurately adjust the hydraulic oil output pressure according to the requirements of the block forming process (such as different pressure requirements in the pre-pressing and forming stages), thereby controlling the downward pressure applied by the telescopic cylinder 16 to the platform 5, avoiding excessive pressure leading to excessive material compression or insufficient pressure affecting the shaping effect. The check valve can prevent hydraulic oil backflow, ensuring that the telescopic cylinder 16 maintains a stable stroke during the pressure application process and preventing the platform 5 from accidentally moving downward.

[0048] See Figure 1 , Figure 2 and Figure 3 In this embodiment, the application of the rolling action fully simulates the forming principle of manual treading of koji, realizing a mechanical structure that imitates manual forming. The rolling mold 3 scans the top contour of the formed koji block and combines it with the rolling motion trajectory to comprehensively design the rolling mold 3, effectively ensuring the shape of the top contour of the koji block after the rolling action is performed. Through the adjustment of the pressing mechanism 1, the step-by-step pressing actions such as pre-pressing and forming are realized, ensuring the gradual process of koji block forming, making the force transmission more gentle, and avoiding problems such as crushing or over-pressing. This device can work in conjunction with other workstations to realize continuous production of the entire koji pressing process, effectively improving the utilization rate of the main functional equipment. The design concept of this device originates from koji making in baijiu (Chinese liquor) and can be expanded. It can not only be used for koji making and other processes in baijiu brewing, but also is suitable for all other scenarios that require similar forming.

[0049] See Figure 1 , Figure 2 and Figure 3 The specific steps for using the biomimetic foot-feeding molding device for brewing koji in this embodiment are as follows: First, after the frame mold 4 carries the material into place, the pressing mechanism 1 is activated. The pressing mechanism 1 lowers the rolling mold 3 and the platform 5 of the actuator to the initial forming position. The rolling mold 3 moves horizontally and rolls horizontally at the speed designed in the program to realize the rolling forming of the curved block. Then, once completed, the pressing mechanism 1 rises, and the rolling die 3 separates from the curved block; Finally, the frame mold 4, carrying the curved block, is conveyed to the next station by the conveyor mechanism. The rolling action can be performed two or more times according to the process requirements, and the number of rolling times can be set.

[0050] Beneficial effects: 1. It imitates manual treading and rolling, and the distribution of curved material and internal tightness are basically the same as those of manual processing.

[0051] 2. The pressing process is a continuous rolling process, which provides uniform and continuous extrusion pressure on the material. This facilitates pressure transmission between material particles and avoids excessive local pressure, which could lead to over-pressing.

[0052] 3. Mechanical cutting will cause some compression, resulting in a loose front end and a tight back end. By utilizing the forming characteristics of roll forming, the roll forming can be started from the tight end, which can alleviate the inconsistency between the front and back to a certain extent and make the material distribution more uniform.

[0053] 4. It greatly reduces labor intensity, replaces manual labor, achieves automation, and ensures the consistency of each piece, solving the problem of inconsistencies in manual operation.

[0054] In addition, this utility model has a compact structure, simple mechanism, stable and reliable operation, and is easy to maintain, which can reduce costs. It also reduces the number of daily maintenance points, thereby reducing daily maintenance costs and risks. It is easy to install and meets the requirements for safe production.

[0055] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
