Description

Technical Field

[0001] The present invention relates to the technical field of liquor making, and particularly relates to a koji pressing die assembly, a koji pressing die rubbing assembly, a koji press and a koji pressing method. Background Art

[0002] In the process of making Chinese liquor, it is necessary to press koji materials into koji blocks. The production process and quality of koji blocks greatly affect the quality and style of liquor. Especially for famous brand Chinese liquors, higher requirements are imposed on the production of koji blocks. In order to improve the pressing efficiency and quality of koji blocks, a variety of automatic koji pressing equipment has been designed. In order to improve the pressing efficiency and automation, a koji press has been designed. For example, a koji press for continuous treading and forming disclosed in the prior art CN101857828B includes a frame, a chain box drive device fixed on the frame for driving and forming the koji block, a koji material conveying device for conveying koji materials into the chain box, and a pressure assembly for pressing the koji materials in the chain box into shape. When making koji blocks, the koji materials are sent into the chain box through the koji material conveying device. The chain box moves the chain box carrying the koji materials under the pressure assembly under the action of the chain box drive device, and then the pressure assembly is started to move the pressing die of the pressure assembly downward to press the koji materials in the chain box into shape. Then, the pressing die of the pressure assembly withdraws from the chain box, and the chain box is moved to the discharging station under the action of the chain box drive device, and the formed koji blocks in the chain box are discharged through the discharging device.

[0003] Although the existing koji presses can greatly improve work efficiency and reduce labor costs, the pressure assembly is a single-action device that moves straight up and down, resulting in its inability to obtain a sufficient slurry extraction effect like manual koji treading. Moreover, when pressing koji, the koji block needs to be in a turtle-back shape, with a tight outer surface and a loose middle, to allow a certain amount of air to enter the koji block, thereby meeting the growth and reproduction of aerobic microorganisms. However, the straight up and down movement of mechanical koji making makes it difficult to ensure the same internal density distribution of the koji block as that during manual koji treading, resulting in the koji block being too tight or too loose inside, which is not conducive to the fermentation of the koji block. Therefore, in order to ensure the high quality of koji making, wineries still retain the manual koji treading method. In view of this, in order to ensure koji making efficiency and improve the quality of koji blocks at the same time, it is necessary to change the structure of the koji pressing die in the koji pressing assembly so that it can simulate manual koji treading during koji pressing, thereby obtaining high-quality koji blocks, improving koji making efficiency, and reducing labor costs.

[0004] Meanwhile, the prior art CN102827719B discloses a pneumatic bending machine. The bending die disclosed therein includes a vibration motor, a die shank sleeve fixed below it, a die shank slidably arranged inside the die shank sleeve and abutted against it through a spring, and a pressing die fixed at the bottom end of the die shank. In this solution, although the artificial stepping on the koji block is simulated through the elastic deformation of the vibration motor and the spring, it only reciprocates vertically. Compared with the existing straight-up-and-down pressure assembly, the improvement effect of the pressing die in this technology is not significant, and there is still a huge difference from artificial koji stepping.

[0025] S6. Start the chain box transmission device, and move the chain box to the discharging port for discharging.

[0026] Due to the adoption of this technical solution, the beneficial effects of the present invention are:

[0027] 1. A bending die assembly, a bending die kneading assembly, a bending machine and a bending method of the present invention can not only position the die shank that needs to move relative to the die shank sleeve through the conical mating part, but also realize the accurate return of the die shank by fitting the tapered part of the die shank sleeve 1 with the tapered part of the die shank, and enable it to move vertically stably, ensuring its perpendicularity to the forming surface at the bottom of the koji block, so as to ensure the accurate alignment of the pressing die and the inner cavity of the chain box. It can also move the die shank relative to the die shank sleeve by compressing the spring to release the conical fit between them, so as to obtain a radial movement space. Then, in addition to the vertical movement space of the die shank within the spring compression stroke, a radial movement space is also provided for the die shank, so as to facilitate the shaking of the entire circumference of the pressing die, making the simulated "koji stepping" more consistent with manual koji stepping. That is, while having the advantages of realizing automatic koji making through mechanical equipment, improving work efficiency, reducing the labor intensity of workers and labor costs, the present invention can also highly restore "manual koji stepping" to obtain a sufficient slurry extraction effect like manual koji stepping and a koji block that is "tight on the outside and loose in the middle" and is convenient for fermentation.

[0028] 2. A bending die assembly, a bending die kneading assembly, a bending machine and a bending method of the present invention. Since the die shank sleeve needs to be fixed on the bearing surface through multiple fastening screws, and the fastening screws are not coaxial with the die shank sleeve, and when tightening the fastening screws, the die shank sleeve will tilt towards this fastening screw due to one fastening screw being turned a few more turns, and then its perpendicularity will decrease. Therefore, in the present invention, the leveling screws are first installed on the bearing surface, and the heads of the leveling screws are coplanar and parallel to the horizontal plane. Then, the die shank sleeve is installed through the fastening screws. In this way, when the die shank sleeve is about to tilt unilaterally, it is restricted by the leveling screws and thus cannot be eccentric, so as to maintain a very high perpendicularity. Correspondingly, the die shank that cooperates with the die shank sleeve can also maintain a very high perpendicularity to ensure the accurate alignment of the pressing die and the inner cavity of the chain box.

[0029] 3. A bending die assembly, a bending die kneading assembly, a bending machine and a bending method of the present invention. The designed chain box transmission device integrates the chain box into the chain originally used to transport the chain box, making the chain box a part of the chain to form a chain with unequal pitches. Thus, two hinged parts can be set on the chain box to improve the stability of the chain box during transmission, prevent adverse situations such as shaking and tipping due to only one hinge point, and ensure the smooth progress of koji pressing. It can also reduce the noise generated by the chain box transmission, protect the quality of the hinged parts on the chain box, and prevent material fatigue.

[0030] 4. A bending die assembly, a bending die kneading assembly, a bending machine and a bending method of the present invention. At the same time, the chain boxes are connected by hinge components with a smaller distance than the chain box axle distance to form a chain with unequal pitches to drive the chain boxes. In this way, a compact chain box assembly can be obtained, and it also has good impact resistance, especially suitable for the high-pressure working environment of koji pressing.

[0031] 5. In a bending die assembly, a bending die kneading assembly, a bending machine, and a bending method of the present invention, the provision of the abutting plate facilitates the seamless combination of the chain boxes on the transmission flat section, thereby ensuring that the koji material from the hopper does not scatter to the periphery and does not fall into the gaps of the frame, meeting the hygiene requirements, with no loss of koji material, and at the same time improving work efficiency.

[0032] 6. In a bending die assembly, a bending die kneading assembly, a bending machine, and a bending method of the present invention, the chain box is arranged in a structure with an open bottom, which facilitates subsequent discharging. When the chain box moves above the discharging hole, the koji material can be ejected from the chain box by gravity or a direct downward thrust, completing the discharging, and improving the convenience of the present invention for koji pressing, conveying, and discharging.

[0033] 7. In a bending die assembly, a bending die kneading assembly, a bending machine, and a bending method of the present invention, the conventional pressure assembly for pressing the koji material is used for preliminary pressing, and the bending die kneading assembly designed in the present invention is used for simulating manual bending. The combination of the two ensures that while the present solution has the advantages of realizing automatic koji making through mechanical equipment, improving work efficiency, reducing the labor intensity of workers and labor costs, it can also highly restore "manual stepping on koji" to obtain a sufficient slurry extraction effect like manual stepping on koji and a koji block with "tight outside and loose inside" which is convenient for fermentation, and further improve the pressing efficiency.

Detailed implementation mode

[0054] In order to make the purpose, technical solution and advantages of the present invention clearer, the following further details the present invention in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention, that is, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0055] The following combines Figures 1 to 16 Make a detailed description of the present invention.

[0056] Embodiment 1

[0057] As Figure 1 shown, a shank assembly of the present invention includes a shank sleeve 1 and a shank slidably installed in the shank sleeve 1 and abutted against the upper side of the inner hole of the shank sleeve 1 through a spring 2. The mutually contacting parts of the shank sleeve 1 and the shank are a conical mating structure, and as the spring 2 is compressed, at the conical mating part, the shank sleeve 1 and the shank are separated from each other.

[0058] During use, the vibration power source drives the shank. The shank sleeve 1 is fixed on the piston rod of the oil cylinder for die pressing, and the bottom of the shank is the die. When performing press bending, the piston rod of the oil cylinder extends outward, so that the die is located in the chain box to press and form the curved material in the chain box; at the same time, the piston rod continues to extend outward, the die together with the shank cannot move downward, and the shank sleeve 1 follows the piston rod and continues to move downward relative to the shank within the compressible stroke of the spring 2. The spring 2 is compressed, and the originally conically mated parts of the shank sleeve 1 and the shank move away from each other and no longer fit, so that a gap is generated radially between the shank sleeve 1 and the shank. At the same time, based on the elastic gap of the spring in the axial direction, under the action of the vibration power source, the shank drives the die to shake, so as to simulate manual stepping on the koji and rub the surface of the koji block, and then make its surface meet the technological requirements of slurry extraction. At the same time, based on the vibration, the die presses the curved material located in the chain box tightly around, while the central part of the curved material remains loose, so as to form a koji block with a tight outer surface and a loose middle, which is beneficial for a certain amount of air to enter the koji block, meets the growth and reproduction of aerobic microorganisms, is beneficial for the fermentation of the koji block, and improves the quality of the produced koji block.

[0059] In the present invention, the shank can be positioned through the conical mating part for the shank that needs to move relative to the shank sleeve. Not only can the taper part of the shank sleeve 1 be fitted with the taper part of the shank to achieve the accurate return of the shank, but also the shank can move vertically stably to ensure its perpendicularity to the forming surface at the bottom of the curved block, thereby ensuring the accurate alignment of the press mold with the inner cavity of the chain box. Moreover, the shank can be moved relative to the shank sleeve by compressing the spring to release the conical fit between them, so as to obtain a radial movement space. Then, in addition to the vertical movement space of the shank within the spring compression stroke, a radial movement space can also be provided for the shank, thus facilitating the overall circumferential wobbling of the press mold to make the simulated "qu stepping" more consistent with manual qu stepping.

[0060] In summary, the shank assembly designed by the present invention has the advantages of realizing automatic qu making through mechanical equipment, improving work efficiency, reducing the labor intensity and labor cost of workers, and at the same time can highly restore "manual qu stepping" to obtain the sufficient slurry extraction effect like manual qu stepping and the curved block that is "tight on the outside and loose in the middle" and is convenient for fermentation.

[0061] Embodiment 2

[0062] To ensure the accurate alignment of the press mold with the inner cavity of the chain box, it is necessary to ensure the perpendicularity of the axis of the shank relative to the forming surface at the bottom of the curved block; and to ensure the perpendicularity of the axis of the shank relative to the forming surface at the bottom of the curved block, it is necessary to ensure the perpendicularity of the axis of the shank sleeve 1 that fits with the shank relative to the forming surface at the bottom of the curved block. Therefore, in this embodiment, a scheme optimization description is required on how to adjust the shank sleeve to obtain better perpendicularity.

[0063] As Figure 1 shown, in the present invention, on the basis of Embodiment 1, an outer turning edge 4 protrudes outward at the circumferential line of the outer wall of the shank sleeve 1. The outer turning edge 4 is threadedly connected to the bearing surface 3 through a plurality of fastening screws 5, and a plurality of leveling screws 6 threadedly installed on the bearing surface 3 are arranged between the outer turning edge 4 and the bearing surface 3, and the head end of the leveling screw 6 contacts the outer turning edge 4.

[0064] Furthermore, the fastening screws 5 and the leveling screws 6 are alternately distributed in sequence along the circumferential line of the shank sleeve 1, and the fastening screws 5 are symmetrically distributed along the axis center of the shank sleeve 1.

[0065] Since the shank sleeve 1 needs to be fixed on the bearing surface 3 by multiple fastening screws, and the fastening screws are not coaxial with the shank sleeve 1, and when tightening the fastening screw 5, the shank sleeve 1 will tilt towards this fastening screw due to one of the fastening screws being turned a few more turns, and then its perpendicularity will decrease. Therefore, in the present invention, the leveling screws are first installed on the bearing surface 3, the heads of the leveling screws are coplanar and parallel to the horizontal plane, and then the shank sleeve 1 is installed through the fastening screws. In this way, when the shank sleeve 1 is to be tilted unilaterally, it is restricted by the leveling screws and thus cannot be eccentric, so as to maintain a very high perpendicularity. Correspondingly, the shank that cooperates with the shank sleeve 1 can also maintain a very high perpendicularity to ensure the precise alignment of the die and the inner cavity of the chain box.

[0066] Further, locking nuts 13 are provided on the leveling screws 6, and one side of the locking nut 13 is in contact with the bearing surface 3. The locking nut 13 is preferably an anti-loosening nut.

[0067] In order to prevent the leveling screws from loosening, after the leveling screws are installed in place, the locking nut 13 is rotated so that its bottom is in contact with the bearing surface 3, increasing the friction between the screw threads of the cooperation between the leveling screw 6 and the bearing surface, thereby preventing the leveling screws from loosening and ensuring the stability of the state of the leveling screws.

[0068] Embodiment 3

[0069] The specific implementation structure of the shank is as follows:

[0070] As Figure 1 shown, the shank includes a shank core 7 and a limit sleeve 8 sleeved on the shank core 7. The spring 2 is sleeved on the shank core 7, and its two ends are respectively abutted against the upper side of the inner hole of the shank sleeve 1 and the upper side of the limit sleeve 8. The limit sleeve 8 is in clearance fit with the inner hole of the shank sleeve 1, and a section of the outer circumferential surface of the shank core 7 is in conical fit with a section of the hole wall of the inner hole of the limit sleeve 8.

[0071] Preferably, the shank core 7 includes an equal-diameter fitting section, an equal-diameter transition section, and a frustum section that is in conical fit with the limit sleeve 8, which are coaxially and sequentially connected and in contact with the limit sleeve 8. The inner hole of the limit sleeve 8 includes a tapered hole that is in fit with the frustum section, and an installation hole that is used to install the spring and has a clearance fit with the fitting section at one end away from the tapered hole. Preferably, the inner diameter of the spring is the same as the diameter of the fitting section.

[0072] Embodiment 4

[0073] As Figure 2 and Figure 3As shown in the figure, a bending die assembly of the present invention includes a die shank assembly, a pressing die 21 fixed to the lower end of the die shank of the die shank assembly, and a vibration power source 14 that applies vibration to the pressing die 21 through the die shank. The die shank assembly includes a die shank sleeve 1 and a die shank slidably installed in the die shank sleeve 1 and abutted against the upper side of the inner hole of the die shank sleeve 1 through a spring 2. The portion where the die shank sleeve 1 and the die shank are in contact with each other is a conical mating structure, and as the spring 2 is compressed, the die shank sleeve 1 and the die shank are separated from each other at the conical mating part.

[0074] The bottom of the pressing die 21 is a forming cavity for forming the upper surface of the curved block, which is the same as the forming cavity of the existing pressing die for pressing the curved block, and is preferably a turtle-back-shaped cavity.

[0075] The top end of the die shank passes through the top of the die shank sleeve 1 and is connected to the vibration power source 14 through a mounting plate 9. Specifically, the core of the die shank passes through the top of the die shank sleeve 1 through a multi-tube and is connected to the vibration power source 14 through a mounting plate 9. The vibration power source 14 is an excitation drive motor, and its motor frame is connected to the mounting plate 9. The mounting plate 9 is fixed above the core of the shank by using countersunk bolts 24.

[0076] The pressing die 21 is fixed to the die shank through a connecting component. The connecting component includes a connecting seat 12 that is connected to the die shank through a first screw 10 and connected to the pressing die 21 through a second screw 11.

[0077] Regarding the connection between the connecting seat 12 and the die shank, based on Embodiment 3, the specific implementation is as follows:

[0078] A positioning hole 22 is provided on the connecting seat 12. The bottom of the core 7 of the die shank protrudes outward to form a small-diameter shaft that cooperates with the positioning hole 22. The shoulder between the small-diameter shaft and the core 7 of the die shank abuts against the connecting seat 12. The first screw 10 is a countersunk screw, and the end of its rod is threadedly connected coaxially with the small-diameter shaft. A washer 23 is sleeved on the first screw 10.

[0079] The second screw 11 is preferably a countersunk screw. One side of the outer circumferential surface of the limiting sleeve 8 close to the connecting seat 12 protrudes outward to form an outward-turned edge and fits with the top surface of the connecting seat 12, thereby increasing the contact surface between the die shank and the connecting seat 12 and ensuring the perpendicularity between the die shank and the upper surface of the connecting seat.

[0080] Embodiment 5

[0081] As Figure 4 and Figure 5As shown in the figure, a kneading component of a bending die of the present invention includes a column 25, a guiding bracket slidably mounted on the column 25, an oil cylinder for driving the guiding bracket to slide up and down along the column 25, and a bending die component fixed on a bearing surface 3 of the guiding bracket. The bending die component is a bending die component, which includes a shank component, a pressing die 21 fixed to the lower end of the shank of the shank component, and a vibration power source 14 for applying vibration to the pressing die 21 through the shank. The shank component includes a shank sleeve 1, a shank slidably mounted in the shank sleeve 1 and abutted against the upper side of the inner hole of the shank sleeve 1 through a spring 2. The part where the shank sleeve 1 and the shank are in contact with each other is a conical mating structure. As the spring 2 is compressed, at the conical mating part, the shank sleeve 1 and the shank are separated from each other, and the shank sleeve 1 is fixed on the bearing surface 3.

[0082] The guiding bracket includes an upper guiding plate 26, a lower guiding plate 27 with a bearing surface 3 on the top surface, and an intermediate cylinder 28 connecting the upper guiding plate 26 and the lower guiding plate 27. Guiding through holes for cooperating with the column 25 are provided on both the upper guiding plate 26 and the lower guiding plate 27, and the intermediate cylinder is sleeved on the column. Guiding sleeves 29 are installed on the guiding through holes. One end of the guiding sleeve 29 is inserted into the annular space between the column and the guiding through hole, and the other end thereof protrudes outward to form an outward-turned edge and is fixed on the upper / lower guiding plate through a set screw. There are multiple columns 25, preferably four.

[0083] An oil cylinder support plate 31 is installed at the top of the column. Here, in order to make a distinction from another set of pressure components later, the oil cylinder is called the second oil cylinder 15, which is installed on the oil cylinder support plate 31.

[0084] Embodiment 6

[0085] A bending machine includes a frame, a chain box transmission device fixed on the frame for a transmission chain box, a curved material conveying device for conveying curved materials into the chain box, and a kneading component of a bending die for pressing and forming the curved materials in the chain box. The kneading component of the bending die includes a column, a guiding bracket slidably mounted on the column, an oil cylinder for driving the guiding bracket to slide up and down, and a bending die component fixed on a bearing surface 3 of the guiding bracket. The bending die component is a bending die component, which includes a shank component, a pressing die 21 fixed to the lower end of the shank of the shank component, and a vibration power source 14 for applying vibration to the pressing die 21 through the shank. The shank component includes a shank sleeve 1, a shank slidably mounted in the shank sleeve 1 and abutted against the upper side of the inner hole of the shank sleeve 1 through a spring 2. The part where the shank sleeve 1 and the shank are in contact with each other is a conical mating structure. As the spring 2 is compressed, at the conical mating part, the shank sleeve 1 and the shank are separated from each other, and the shank sleeve 1 is fixed on the bearing surface 3. The bracket is fixed on the frame.

[0086] The press-bending machine is equipped with a control system that flexibly controls various working instructions of the hydraulic integrated pump station, oil cylinder, drive motor, servo motor, etc. by software through various working detection devices. During actual implementation, flexible regulation can be carried out according to production volume and process requirements. For example, the control system can be connected to the front-section raw material conveying equipment, hair moistening equipment, crushing equipment, mixing equipment, moistening equipment, koji material loosening equipment, rear-section koji block stacking equipment, and conveying and warehousing equipment, so as to integrate relevant controls to form automated production in combination.

[0087] On one side of the kneading component of the press-bending mold close to the koji material conveying device, a first pressure component is provided. The first pressure component adopts a conventional pressure component, which preliminarily presses and forms the koji material in the chain box. The koji material after being pressed by the first pressure component is then repeatedly kneaded by the kneading component of the press-bending mold to simulate manual press-bending.

[0088] In order to further improve the convenience of koji making of the press-bending machine designed by this solution, preferably, a spraying device for spraying water into the mold box is installed on the frame. The spraying device is preferably configured with atomizing nozzles, so that the water can be atomized more finely and sprayed more evenly, and then a fine mist is evenly distributed on the surface of the koji block, which is not only convenient for subsequent kneading to produce slurry, but also convenient for demolding after the koji block is formed.

[0089] Furthermore, as Figure 8 shown, the chain box transmission device includes a driving sprocket 9a and a driven sprocket 10a rotatably installed on the frame, an endless transmission chain sleeved on the driving sprocket 9a and the driven sprocket 10a, and a power output device for driving the driving sprocket 9a to rotate. The endless transmission chain includes a plurality of chain boxes 1a and a plurality of hinge components. The chain boxes 1a and the hinge components are arranged alternately in sequence and are successively hinged end to end to form an annular structure. Meshing portions 2a meshing with the teeth of the sprocket are provided on the hinge components;

[0090] The inner cavity of the chain box 1a penetrates through the bottom of the chain box 1a. A material supporting plate 11a fixed on the frame is arranged between the driving sprocket 9a and the driven sprocket 10a. The bottom of the chain box 1a close to the kneading component of the press-bending mold is attached to the upper surface of the material supporting plate 11a, and a discharge hole 12a for discharging the koji blocks in the chain box is provided at one end of the material supporting plate 11a far from the feeding end of the chain box.

[0091] This chain box transmission device designed by the present invention integrates the chain box into the chain originally used for conveying the chain box, so that the chain box becomes a part of the chain, forming an unequal pitch chain; thus, two hinged parts can be provided on the chain box to improve the stability of the chain box during the transmission process, prevent adverse situations such as shaking and tipping due to only one hinge point, and ensure the smooth progress of koji pressing; and it can also reduce the noise generated by the chain box transmission, protect the quality of the hinged parts on the chain box, and prevent material fatigue.

[0092] At the same time, the chain boxes are connected by hinge assemblies that are smaller than the wheelbase of the chain boxes to form unequal pitch chains to drive the chain boxes. This allows for a compact chain box assembly with good impact resistance, which is particularly suitable for high-pressure working environments such as koji pressing.

[0093] like Figure 9 As shown, abutment plates 3a are provided on the upper sides of the front and rear ends of the chain box 1a. When the vertical center lines of two adjacent chain boxes 1a are parallel to each other, the abutment plates 3a on the opposite surfaces thereof contact each other. The provision of the abutment plates 3a facilitates the seamless combination of the chain boxes on the transmission flat section, thereby ensuring that the bent material from the hopper does not scatter to the periphery and does not fall into the gap of the frame, so as to meet the hygienic requirements, without loss of bent material, and also improve the work efficiency.

[0094] The abutment plate 3a may be provided by welding, clamping, riveting, etc. In the present embodiment, the abutment plate 3a is preferably formed by the upper protrusion of the corresponding side wall of the chain box 1a.

[0095] The implementation of the hinge assembly is as follows:

[0096] Of the two adjacent chain boxes 1a, one is chain box A and the other is chain box B;

[0097] like Figure 10 and Figure 11 As shown, the hinge assembly includes an inner link plate 4a, an outer link plate 5a and two pins 6a, one end of the inner link plate 4a, one end of the outer link plate 5a and one side of the chain box A close to the chain box B are hinged through a pin 6a; the other end of the inner link plate 4a, the other end of the outer link plate 5a and one side of the chain box B close to the chain box A are hinged through another pin 6a;

[0098] There is a distance between the inner link plate 4a and the outer link plate 5a, and the space between them and the area between the two pin shafts 6a is the meshing portion 2a.

[0099] Furthermore, rollers 7a are sleeved on the pins 6a, and the space between the inner link plate 4a and the outer link plate 5a and the area between the two rollers 7a is the meshing portion 2a. The provision of the rollers 7a can reduce the friction between the sprocket teeth and the pins 6a when the holes between the pins 6a are meshed, thereby reducing friction loss and noise, and increasing the service life of the present invention.

[0100] Preferably, the inner link plate 4a and the chain box 1a are both matched with the pin 6a through rolling bearings, thereby reducing the friction between the pin and the corresponding components, thereby reducing friction loss, increasing the service life of the present invention, and reducing the frequency of subsequent maintenance.

[0101] Preferably, the number of independent chambers inside the chain box 1a is not less than 1a. According to the actual required curved blocks, various sizes of inner cavities can be configured. For example, when a larger curved block is needed, one independent chamber can be configured inside the chain box 1a; when a smaller one is needed, two independent chambers can be configured, as Figure 10 shown.

[0102] Furthermore, long chain plates 8a are arranged between every two adjacent hinge assemblies. The two ends of each long chain plate 8a are respectively fitted with a pin shaft 6a, and the two pin shafts 6a fitted with the long chain plate 8a are both hinged to the same chain box 1a.

[0103] The arrangement of the long chain plates strengthens the strength at the chain box and prevents its deformation; at the same time, it can also improve the accuracy of the entire transmission.

[0104] The driving sprocket 9a is mounted on the frame by a driving bearing structure, as Figure 15 shown. The driving bearing structure includes a driving sprocket shaft 16a whose two ends are respectively rotationally supported on the frame by a driving bearing seat 17a. The driving sprocket 9a is fixed to the driving sprocket shaft 16a by a key, and the teeth of the driving sprocket 9a mesh with the meshing part 2a of the chain box assembly. One end of the driving sprocket shaft 16a extends out and is key-connected to the power transmission sprocket 18a; the power transmission sprocket 18a is drivingly connected to the power output sprocket 21a by a precision roller chain 22a, the power output sprocket 21a is key-fixed to the output shaft of the servo reduction motor 19a, and the servo reduction motor 19a is fixed to the frame by a motor mounting bracket, as Figure 16 shown.

[0105] Since the chain box assembly is an unequal pitch chain structure, the corresponding sprockets configured are unequal pitch sprockets, as Figure 13 shown.

[0106] The driven sprocket 10a is mounted on the frame by a driven bearing structure, as Figure 14 shown. The driven bearing structure includes a driven sprocket shaft 14a whose two ends are respectively rotationally supported on the frame by a driven bearing seat 15a; the driven sprocket 10a is key-fixed to the driven sprocket shaft 14a and the teeth of the driven sprocket 10a mesh with the meshing part 2a of the chain box assembly.

[0107] Preferably, both sides of each chain box along the conveying direction are hinged to the adjacent chain boxes through hinge assemblies. Correspondingly, two driven sprockets 10a and two driving sprockets are configured, as Figure 14 and Figure 15 shown.

[0108] Furthermore, as Figure 8As shown, the inner cavity of the chain box 1a runs through the bottom of the chain box. A material supporting plate 11a fixed to the frame is arranged between the driving sprocket 9a and the driven sprocket 10a. The bottom of the chain box is attached to the upper surface of the material supporting plate 11a. A discharge hole 12a for discharging the curved block in the chain box is arranged at one end of the material supporting plate 11a far from the end where the chain box is loaded.

[0109] The chain box is configured with an open-bottom structure, which facilitates subsequent discharging. When the chain box moves above the discharge hole 12a, it can be removed from the chain box 1a by gravity or a direct downward thrust, completing the discharging, thus improving the convenience of the present invention for koji pressing, conveying, and discharging.

[0129] In this embodiment, the conventional pressure component for pressing the koji material is used for preliminary pressing, and the kneading component of the koji pressing die involved in the present invention is used for simulating manual koji pressing. Combining these two can, while ensuring that this solution has the advantages of realizing automatic koji making through mechanical equipment, improving work efficiency, reducing the labor intensity and labor cost of workers, restore "manual koji stepping" relatively highly, obtain a sufficient slurry extraction effect like that of manual koji stepping and a koji block that is "tight on the outside and loose in the middle" which is convenient for fermentation, and further improve the pressing efficiency.

[0130] In the present invention, the koji material is crushed by a mill and then mixed with water according to process requirements, and evenly enters the hopper of the koji material conveying device, and then feeds the chain box; the chain box is driven by a stepping motor to run to the first group of pressure components, and the rodless cavity of the first oil cylinder of the first group of pressure components is supplied with oil, and the piston rod of the first oil cylinder works downward, driving the pressing die connected to the end of the piston rod of the oil cylinder to insert downward along the column guide into the chain box, and initially forming the koji material in the chain box; subsequently, the rod cavity of the first oil cylinder is supplied with oil, and the piston rod retracts, that is, the piston rod returns upward, and the pressing die also returns with it. Then, the stepping motor drives the chain box to run under the koji pressing die kneading component designed by the present invention, and the rodless cavity of the second oil cylinder at the upper part of the koji pressing die kneading component is supplied with oil, and its piston rod works downward, driving the pressing die with a turtle-back-shaped cavity connected to the oil cylinder to move downward along the column guide to a preset position. The pressing die repeatedly kneads and extracts slurry from the turtle-back surface of the formed koji blank in the chain box through the vibration drive motor, spring, and the axial and radial gaps between the die shank and the die shank sleeve arranged on it; after completing the kneading and slurry extraction, the rod cavity of the oil cylinder is supplied with oil, and the piston rod returns upward, and the pressing die also returns with it; then, the stepping motor drives the chain box to run under the ejector device installed on one side of the second group of pressing die components, and the koji blank in the chain box is pushed out by the downward push of the ejector device, and the koji blank enters the output device and is output by the output device. This method simulates the processes of manual stepping for shaping and kneading the turtle-back surface to extract slurry, and the produced koji blocks fully meet the process requirements of being tight on the outside and loose on the inside and having slurry extraction on the turtle-back surface. Moreover, the koji blocks can be continuously pressed and kneaded step by step, and the production speed of the koji blocks can reach 15 pieces per minute, improving the production efficiency of the koji blocks and also improving the later fermentation quality of the koji blanks.

[0131] The koji pressing method designed by the present invention is particularly suitable for the brewing of strong-flavor, sauce-flavor, and light-flavor Baijiu, a stepping-type circulating koji press with adjustable pressure and speed, and its forming and kneading koji-making method.

Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
