[0002] Koji making is an important part of the brewing process, which mainly refers to converting starchy raw materials into saccharified substances required for fermentation. Before koji making, the koji material needs to be pressed into shape using a koji press, so as to improve the fermentation efficiency and facilitate the quality control during the brewing process; when the koji press is working, the koji head reciprocates up and down, exerting pressure on the koji material below it, thereby pressing the koji material into shape, and the amount of pressure depends on the final compression of the spring.

[0064] Embodiment:

[0065] As Figure 1As shown in the figure, an embodiment of the present application discloses a pressure-adjustable bending mechanism, which is used to generate pressure on the curved material for pressing and forming. Its specific structure includes: a cross beam 1, a plurality of bending units 2, and a driving mechanism 3.

[0066] The cross beam 1 has a square column structure, which is convenient for the installation of other components. A plurality of mounting through holes 11 arranged side by side at intervals are provided on the top surface; the mounting through holes 11 vertically penetrate the cross beam 1, and are evenly spaced along the axis direction of the cross beam 1, so as to ensure uniform pressure distribution and improve the pressing and forming effect.

[0067] Exemplarily, sleeves are provided on both sides of both ends of the cross beam 1, and the sleeves are movably sleeved on the vertically arranged guide rods, so as to guide the cross beam 1 to move up and down, improving the bending stability.

[0068] Exemplarily, support seats are provided at the top of both ends of the cross beam 1. The support seats are used for detachably installing a horizontally arranged cross bar, and the power source is connected to the cross bar through a crank and connecting rod mechanism, so as to drive the cross beam 1 to perform reciprocating up and down movements. Its movement is stable and it is convenient for disassembly, installation and maintenance.

[0069] A plurality of bending units 2 correspond to the mounting through holes 11 one by one. In this embodiment, six are provided, but not limited thereto. There can be fewer or more, which are set according to actual needs, so no specific limitation is made.

[0070] Specifically, as Figure 2 and Figure 3 shown, the bending unit 2 includes:

[0071] A support shaft 21, which is vertically arranged and passes through the mounting through hole 11;

[0072] A limiting member 22, which is installed at the top end of the support shaft 21. The diameter of the limiting member 22 is larger than the diameter of the mounting through hole 11, and is used to limit and prevent the support shaft 21 from detaching from the mounting through hole 11;

[0073] A bending head 23, which is installed at the bottom end of the support shaft 21; the bending head 23 has a square structure and is used for pressing and forming the curved material;

[0074] A bushing 24, which is movably sleeved on the support shaft 21, and the upper end is inserted into the mounting through hole 11 and can slide up and down therein; the bushing 24 is circumferentially limited and can only slide up and down along the mounting through hole 11, and an external thread matched with an adjusting ring 25 is provided on the outer periphery of the lower end;

[0075] An adjusting ring 25, which is threadedly connected to the bushing 24 and is located below the cross beam 1; an internal thread matched with the external thread on the bushing 24 is provided on the inner periphery of the adjusting ring 25, so that it can move up and down relative to the bushing 24 after rotation;

[0076] The spring 26 is movably sleeved on the support shaft 21 and is supported between the bushing 24 and the bending head 23;

[0077] The driving mechanism 3 is installed on the cross beam 1 and is in transmission connection with each adjusting ring 25 for driving the adjusting rings 25 to rotate simultaneously.

[0078] During operation, driven by the power mechanism, the cross beam 1 reciprocates up and down. Then, the pressing force is sequentially transmitted through the cross beam 1, the adjusting ring 25, the bushing 24, the spring 26, and the bending head 23, and finally applied to the curved block. Among them, the maximum value of the pressing force depends on the final compression amount of the spring 26.

[0079] When the adjusting ring 25 is at the highest position on the bushing 24, the distance between the adjusting ring 25 and the cross beam 1 is 0. Thus, when pressing the block, when the bending head 23 contacts the curved block, the spring 26 starts to compress. At this time, the final compression amount of the spring 26 is the largest, so the pressing force is also the largest.

[0080] When the adjusting ring 25 is at the lowest position on the bushing 24, there is a certain distance between the adjusting ring 25 and the cross beam 1, assumed to be a. Thus, when pressing the block, after the bending head 23 contacts the curved block, the pressing unit 2 as a whole rises relative to the cross beam 1 until the distance between the adjusting ring 25 and the cross beam 1 is 0, and then the spring 26 starts to compress. Therefore, the final compression amount of the spring 26 is reduced by the value of a. At this time, the final compression amount of the spring is the smallest, so the pressing force is also the smallest.

[0081] During adjustment, the driving mechanism 3 drives each adjusting ring 25 to rotate simultaneously, so that each adjusting ring 25 can displace the same distance relative to the corresponding bushing 24. Thus, the distance between the adjusting ring 25 and the cross beam 1 can be arbitrarily set within the range of 0 to a, so as to achieve the effect that the pressing forces for multiple times are all different.

[0082] The utility model drives each adjusting ring 25 to rotate synchronously through the driving mechanism 3, thereby adjusting its relative position on the corresponding bushing 24, so as to realize the change of the final compression amount of the spring 26 and finally realize the change of the pressing force. It can meet the diverse production and use requirements and improve the applicability.

[0083] In some embodiments, as Figures 1 to 3 shown, the adjusting ring 25 is an adjusting gear, and a layout area 12 is formed on the cross beam 1 between two adjacent pressing units 2. The driving mechanism 3 includes:

[0084] The driving unit 31 is installed in any one layout area 12 and is in transmission connection with two adjacent adjusting gears; the driving unit 31 is used for driving two adjacent adjusting rings 25 to rotate and does not interfere with their up and down displacement;

[0085] A plurality of transmission units 32 are respectively installed in the remaining layout areas 12 one by one, and each transmission unit 32 is in transmission connection with two adjacent adjusting gears; the transmission unit 32 is used to realize the power transmission between two adjacent adjusting rings 25, so that they rotate without interfering with the up and down displacement.

[0086] Exemplarily, the driving unit 31 is installed in the central layout area 12, which improves the stability of power transmission and ensures the uniform stress of the overall structure.

[0087] Through the above settings, each adjusting ring 25 can be stably driven to rotate synchronously without interfering with its up and down displacement, thereby ensuring the stability of buckling.

[0088] Based on the above embodiment, as Figures 1 to 3 shown, the driving unit 31 includes:

[0091] A driving gear 313 is fixedly sleeved on the transmission shaft 311, is located below the cross beam 1, and meshes with two adjacent adjusting gears.

[0092] During operation, the motor 312 drives the transmission shaft 311 to rotate, thereby driving the driving gear 313 to rotate. The driving gear 313 drives the adjusting gear to rotate. Thus, the adjusting gear moves up and down and still remains meshed with the driving gear 313.

[0093] Through the above design of the driving unit 31, power can be stably output, and the structure is simple and compact, which is convenient for installation and layout.
