Description

Technical Field

[0001] This application relates to the field of food processing technology, and in particular to a koji-making apparatus. Background Technology

[0002] During the koji-making process, the disc of the disc koji-making machine is used to accumulate materials. The materials on the disc are turned over by a material turner. After koji-making, a conveyor is used to transport the materials outside the disc. Traditionally, there are two implementation methods. One method involves a fixed disc: the material turner rotates around the center of the disc to turn the materials on it. After koji-making, a conveyor rotates around the center of the disc to transport the materials outside. Because layered conveying is used, the conveyor needs to have a lifting function to move up and down, transporting the materials on the disc in layers. The other method involves the disc rotating around its center: the material turner is fixed in the radial direction of the disc, controlling its rotation. As the disc rotates, the materials are turned over. A conveyor is fixed in the radial direction of the disc and can move up and down to transport the materials on the rotating disc. Whether the structure is fixed or rotates around the center, there is a relative motion between the two components. When the crank is fixed, both the turning machine and the conveyor need to rotate around the center, and the conveyor also needs to move up and down, making the drive complex. When the crank rotates around the center, the crank rotates around the center, and the conveyor moves up and down. The relative motion components of these two structural forms are distributed on two parts, which requires high precision in the processing and installation of these two parts. Utility Model Content

[0003] Therefore, it is necessary to provide a koji-making device that can keep the turning machine and the conveyor relatively fixed, thereby reducing the difficulty of processing and installation.

[0004] One embodiment of this application provides a koji-making apparatus.

[0005] A koji-making apparatus includes a koji-making cylinder, a material-turning mechanism, a conveying mechanism, a koji disc, a lifting mechanism, and a rotating mechanism. The material-turning mechanism is connected to the koji-making cylinder to turn the material on the koji disc. The conveying mechanism is connected to the koji-making cylinder to convey material to the koji disc inside the koji-making cylinder. The koji disc is located inside the koji-making cylinder. The koji disc is installed on the lifting mechanism and can move up and down under the drive of the lifting mechanism. The rotating mechanism is installed on the koji-making cylinder and connected to the lifting mechanism, and the rotating mechanism is used to drive the lifting mechanism and the koji disc to rotate.

[0006] In some embodiments, the conveying mechanism includes a feed screw and a conveying drive component, wherein at least a portion of the feed screw extends into the fermentation cylinder, the conveying drive component is mounted on the fermentation cylinder and connected to the feed screw, and the conveying drive component is used to drive the feed screw to rotate and feed material.

[0007] In some embodiments, the fermentation cylinder has a columnar structure, and a feed inlet is provided on the side wall of the fermentation cylinder. The conveying mechanism is installed on the side wall of the fermentation cylinder and communicates with the feed inlet.

[0008] In some embodiments, the number of conveying mechanisms is multiple.

[0009] In some embodiments, the material turning mechanism includes a material turning screw and a material turning drive component. The material turning screw extends into the fermentation cylinder and is rotatably connected to the material turning drive component. The material turning drive component is installed in the fermentation cylinder to drive the material turning screw to rotate and turn the material on the fermentation tray.

[0010] In some embodiments, the material turning mechanism is mounted on top of the fermentation cylinder.

[0011] In some embodiments, the number of the material turning mechanism is multiple.

[0012] In some embodiments, the lifting mechanism includes a lead screw assembly and a lifting drive component. The lead screw assembly is located inside the koji-making cylinder and extends along the height direction of the koji-making cylinder. The lifting drive component is mounted on the koji-making cylinder and connected to the lead screw assembly to drive the lead screw assembly to rotate. The koji disc is rotatably connected to the lead screw of the lead screw assembly.

[0013] In some embodiments, the lead screw assembly includes a lead screw, a guide post, and a slider. The lead screw and the guide post are arranged parallel to each other in the koji-making cylinder and extend along the height direction of the koji-making cylinder. The slider is threaded to the lead screw and slidably connected to the guide post. The koji disc is connected to the slider. The lifting drive component is connected to the lead screw to drive the lead screw to rotate.

[0014] In some embodiments, the rotating mechanism includes a first rotating seat, a second rotating seat, and a rotating drive component. The first rotating seat and the second rotating seat are rotatably connected to the top and bottom of the koji-making cylinder, respectively. The lifting mechanism is installed between the first rotating seat and the second rotating seat. The rotating drive component is connected to the first rotating seat and / or the second rotating seat to drive the first rotating seat, the second rotating seat, and the lifting mechanism to rotate synchronously.

[0015] The koji-making apparatus of this application improves upon the existing koji disc structure by utilizing a lifting and rotating mechanism to drive the koji disc to achieve lifting and rotational movements. This concentrates the relative motion on the koji disc structure, thereby fixing the material-turning mechanism and conveying mechanism relative to the koji-making cylinder. The conveying mechanism delivers material to the koji disc inside the koji-making cylinder, while the material-turning mechanism flips the material on the koji disc. This application achieves koji-making by driving the lifting and rotation of the koji disc, which, in conjunction with the material-turning and conveying mechanisms, performs the feeding and turning of material. The material-turning and conveying mechanisms do not participate in the lifting and rotational movements, resulting in a simple structure, centralized drive, and low cost.

[0027] This application provides a koji-making device to solve the following technical problems existing in traditional koji-making techniques: when a koji disc is used for fixing, both the turning machine and the conveyor need to rotate around the center, and the conveyor also needs to move up and down, making the drive complex; when the koji disc rotates around the center, the koji disc rotates around the center, and the conveyor moves up and down; the relative motion components of the above two structural forms are distributed on two parts, requiring high precision in the processing and installation of these two parts. The koji-making device will be described below with reference to the accompanying drawings.

[0028] The koji-making apparatus provided in this application embodiment is exemplary; please refer to [link to example]. Figure 1 As shown, Figure 1 This is a schematic diagram of the koji-making apparatus provided in an embodiment of this application. The koji-making apparatus of this application can be used for koji making, and during the koji-making process, the koji tray can move up and down and rotate.

[0029] To more clearly illustrate the structure of the koji-making device, the following description will be provided in conjunction with the accompanying drawings.

[0030] For example, please refer to Figure 1 As shown, a koji-making apparatus 10 includes a koji-making cylinder 100, a material-turning mechanism 200, a conveying mechanism 300, a koji tray 400, a lifting mechanism 500, and a rotating mechanism 600. The material-turning mechanism 200 is connected to the koji-making cylinder 100 to turn the material on the koji tray 400. The conveying mechanism 300 is connected to the koji-making cylinder 100 to convey material onto the koji tray 400 inside the koji-making cylinder 100. The koji tray 400 is located inside the koji-making cylinder 100. The koji tray 400 is mounted on the lifting mechanism 500 and can move up and down under the drive of the lifting mechanism 500. The rotating mechanism 600 is mounted on the koji-making cylinder 100 and connected to the lifting mechanism 500. The rotating mechanism 600 is used to drive the lifting mechanism 500 and the crank plate 400 to rotate synchronously. That is, in this application, the lifting mechanism 500 and the crank plate 400 can rotate synchronously on the horizontal axis under the drive of the rotating mechanism 600. The lifting mechanism 500 can drive the crank plate 400 to move up and down in the vertical direction, thus realizing the rotation and lifting of the crank plate 400. The material turning mechanism 200 and the conveying mechanism 300 do not participate in the above driving action.

[0031] In some embodiments, the conveying mechanism 300 includes a feed screw 310 and a conveying drive component 320. At least a portion of the feed screw 310 extends into the fermentation cylinder 100. The conveying drive component 320 is mounted on the fermentation cylinder 100 and connected to the feed screw 310. The conveying drive component 320 drives the feed screw 310 to rotate and feed the material.

[0032] See Figure 1 As shown, the feed screw 310 runs along the radial direction of the fermentation cylinder 100, along... Figure 1 As shown, the feed screw 310 extends horizontally and along a direction perpendicular to the height of the koji cylinder 100, reducing the impact on the lifting and lowering of the koji disk 400 and maximizing the clearance for the lifting and lowering movement of the koji disk 400.

[0033] In some embodiments, the fermentation cylinder 100 has a columnar structure. A feed inlet is provided on the side wall of the fermentation cylinder 100. A conveying mechanism 300 is mounted on the side wall of the fermentation cylinder 100 and communicates with the feed inlet. The conveying mechanism 300 feeds material through the side wall of the fermentation cylinder 100, without affecting the lifting and lowering movement of the fermentation disc 400.

[0034] In some embodiments, the number of conveying mechanisms 300 is multiple.

[0035] Preferably, the shape of the curved plate 400 can be adapted to the shape of the cavity of the koji-making cylinder 100. For example, when the koji-making cylinder 100 is a cylindrical structure, the curved plate 400 is circular, and the periphery of the curved plate 400 is fitted with the inner wall of the koji-making cylinder 100 with a clearance to ensure that the curved plate 400 is not obstructed by the inner wall of the koji-making cylinder 100 when rotating. Alternatively, the shape of the curved plate 400 may not be adapted to the cavity of the koji-making cylinder 100, that is, the curved plate 400 can also be other shapes, such as the koji-making cylinder 100 being cylindrical and the curved plate being elliptical. In this case, a certain gap can be provided between the edge of the curved plate 400 and the inner wall of the koji-making cylinder 100. The shape of the curved plate 400 is determined so as not to be limited by the inner wall of the koji-making cylinder 100.

[0036] In some of these embodiments, see Figure 1 As shown, the material turning mechanism 200 includes a material turning screw 210 and a material turning drive component 220. The material turning screw 210 extends into the fermentation cylinder 100 and is rotatably connected to the material turning drive component 220. The material turning drive component 220 is mounted on the fermentation cylinder 100 to drive the material turning screw 210 to rotate and turn the material on the fermentation tray 400.

[0037] See Figure 2 As shown, Figure 2 This is a cross-sectional schematic diagram of a koji-making device 10 according to an embodiment of this application. The material-turning screw 210 is located above the koji disk 400. The material-turning screw 210 does not affect the lifting and lowering movement of the koji disk 400, and can also realize that the material fed by the material-turning screw 210 falls directly onto the koji disk 400 under the action of gravity.

[0038] In some embodiments, the material turning mechanism 200 is mounted on the top of the fermentation cylinder 100. In this case, the material turning screw 210 extends along the height direction of the fermentation cylinder 100 into the cylinder 100 to turn the material on the fermentation tray 400. The material turning screw 210 enables the turning of the material.

[0039] In some embodiments, there are multiple material turning mechanisms 200. The multiple material turning mechanisms 200 are spaced apart, enabling the turning of materials at different positions on the curved plate 400, thus improving the turning effect.

[0040] In some of these embodiments, see again Figure 1 As shown, the lifting mechanism 500 includes a lead screw assembly 510 and a lifting drive component 520. The lead screw assembly 510 is located inside the fermentation cylinder 100 and extends along the height direction of the fermentation cylinder 100. The lifting drive component 520 is mounted on the fermentation cylinder 100 and connected to the lead screw assembly 510 to drive the lead screw assembly 510 to rotate. The crank plate 400 is rotatably connected to the lead screw 511 of the lead screw assembly 510. Using the lead screw assembly 510 can improve the stability of the crank plate 400 during the lifting process.

[0041] In some embodiments, the lead screw assembly 510 includes a lead screw 511, a guide post 512, and a slider 513. The lead screw 511 and the guide post 512 are arranged parallel to each other within the koji-making cylinder 100 and extend along the height direction of the koji-making cylinder 100. The slider 513 is threadedly connected to the lead screw 511 and slidably connected to the guide post 512. The koji disc 400 is connected to the slider 513. The lifting drive component 520 is connected to the lead screw 511 to drive the lead screw 511 to rotate.

[0042] In some of these embodiments, see Figure 2 As shown, the lead screw 511 is located at the center of the radial direction of the koji-making cylinder 100. For example, when the koji-making cylinder 100 has a cylindrical structure, the lead screw 511 is located on the central axis of the koji-making cylinder 100.

[0043] In some embodiments, the rotating mechanism 600 includes a first rotating seat 610, a second rotating seat 620, and a rotating drive component 630. The first rotating seat 610 and the second rotating seat 620 are rotatably connected to the top and bottom of the fermentation cylinder 100, respectively. Preferably, the first rotating seat 610 and the second rotating seat 620 are rotatably connected to the top and bottom surfaces of the fermentation cylinder 100, respectively. A lifting mechanism 500 is installed between the first rotating seat 610 and the second rotating seat 620. The rotating drive component 630 connects the first rotating seat 610 and / or the second rotating seat 620 to drive the first rotating seat 610, the second rotating seat 620, and the lifting mechanism 500 to rotate synchronously.

[0044] In some embodiments, the first rotating seat 610 and the second rotating seat 620 can be detachably connected to the fermentation cylinder 100, which facilitates the maintenance, cleaning and other work of the fermentation cylinder 100.

[0045] In some embodiments, the conveying drive component 320, the turning drive component 220, the lifting drive component 520, and the rotating drive component 630 may each be a drive motor.

[0046] In some embodiments, the aforementioned koji-making apparatus 10 further includes a control mechanism. The control mechanism is electrically connected to the material-turning mechanism 200, the conveying mechanism 300, the lifting mechanism 500, and the rotating mechanism 600. Specifically, the control mechanism is electrically connected to the conveying drive component 320, the material-turning drive component 220, the lifting drive component 520, and the rotating drive component 630. The control mechanism is not shown in the accompanying drawings.

[0047] In some embodiments, the control mechanism may be a PLC (Programmable Logic Controller).

[0048] In summary, the koji-making apparatus 10 of this application improves upon the existing koji disk 400 structure by utilizing the lifting mechanism 500 and the rotating mechanism 600 to drive the koji disk 400 to achieve lifting and rotating motions. This concentrates the relative motion on the koji disk 400 structure, thereby fixing the material-turning mechanism 200 and the conveying mechanism 300 relative to the koji-making cylinder 100. The conveying mechanism 300 conveys materials to the koji disk 400 within the koji-making cylinder 100, and the material-turning mechanism 200 flips the materials on the koji disk 400. This application achieves koji-making by driving the lifting and rotating of the koji disk 400, which, in conjunction with the material-turning mechanism 200 and the conveying mechanism 300, performs material-turning operations. The structure is simple to install, the drive is centralized, and the cost is low.

[0049] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
