Description

Technical Field

[0001] The utility model relates to the technical field of koji making, in particular to a koji block pressing machine. Background Art

[0002] Koji making is an important link in the brewing process, mainly referring to the conversion of starchy raw materials into saccharifying substances required for fermentation; before koji making, it is necessary to use a koji block pressing machine to press the koji material into a mold, so as to improve the fermentation efficiency and facilitate the control of the quality in the brewing process.

[0003] At present, the commonly used mechanical koji block pressing machines on the market usually adopt a movable koji box and a fixed pressing head type; its working process is as follows: the koji box drives the koji material to perform a step-by-step cyclic movement, the pressing head moves up and down at a fixed position, and during this process, it falls into the koji box to apply pressure to the koji material, so that the koji material is successively pressed into a mold one by one. It imitates the traditional koji stepping process and discharges the material after multiple pressings. As shown in the attached instruction Figure 15 As shown, the koji box successively receives materials, pre-presses, forms, and discharges materials from right to left at the upper part of the equipment.

[0004] However, the existing koji block pressing machines still have the following problems:

[0005] First, since workstations such as feeding, koji pressing, and discharging are arranged in a straight line direction, more empty workstations are required for the cyclic movement of the koji box, resulting in a large number of empty-workstation koji boxes, making the length of the equipment longer and the floor area larger, which is not conducive to the actual installation and layout;

[0006] Second, a large number of koji boxes perform a step-by-step cyclic movement, so there are problems of complex transmission and high movement accuracy, which lead to the equipment being prone to failures and poor actual use effects;

[0007] Third, the koji material is gradually advanced by the koji box and then successively pressed by each pressing head, which causes the koji box to drag and collide with other components during movement, thus generating a large amount of noise; and the koji material and the koji box need to move a long distance, so there is also a problem of high energy consumption. Summary of the Utility Model

[0120] Embodiment:

[0121] As Figure 1 and Figure 2 shown, an embodiment of the present application discloses a koji block press for pressing koji materials into shape in the koji making step of the brewing process, including: a frame 1, a feeding bin 2, a transfer mechanism 3, a formed koji mechanism 4, a pre-pressing mechanism 5, a koji pressing mechanism 6, a backing plate 7, a fifth driving unit 8, a conveyor 9, and multiple square tubes.

[0122] The frame 1 has a box structure for carrying and installing the rest of the moving parts, and is provided with guard plates around it to protect the internal parts from external interference.

[0123] The feeding bin 2 has openings at both the upper and lower ends and is installed on the frame 1; as Figure 3 and Figure 4 shown, a support frame is sleeved on the outer periphery of the feeding bin 2, and the support frame is installed on the top surface of the frame 1 through columns at the four corners, which plays a role of stable support.

[0124] The transfer mechanism 3 is arranged below the feeding bin 2 for receiving materials at the receiving position, quantitatively conveying the koji materials to the pre-pressing position, and sending them into the koji box 4a. As Figures 5 - 7 shown, the specific structure includes:

[0125] A transfer box 31 with openings at both the upper and lower ends, and the upper opening corresponds to the lower opening of the feeding bin 2;

[0126] Multiple first partition plates 32 are vertically arranged and are installed in the transfer box 31 at intervals along the Y-axis direction for separating and forming multiple material boxes 3a; the first partition plates 32 are preferably set to five and evenly distributed, so as to separate and form six material boxes 3a, but not limited thereto, and no specific limitation is made;

[0128] The first driving unit 34 is installed on the frame 1 and is in driving connection with the transfer box 31 for driving the transfer box 31 to reciprocate along the X-axis direction.

[0129] The bending mechanism 4 is arranged below the transfer mechanism 3. Figures 8 - 9 As shown, the specific structure includes:

[0130] The bend box 41 has upper and lower openings, and the upper opening corresponds to the lower opening of the transfer box 31;

[0131] A plurality of second partitions 42 are vertically arranged and installed in the finished bend box 41 at intervals along the Y-axis direction, and are used to separate and form a plurality of bend boxes 4a corresponding to the material boxes 3a one by one; the second partitions 42 are preferably arranged in five pieces and evenly distributed, so as to separate and form six bend boxes 4a, but are not limited thereto and are not specifically limited thereto;

[0132] The second baffle 43 is horizontally arranged on one side of the bending box 41 in the negative direction of the X-axis, and the top surface can be in contact with the bottom surface of the transfer box 31, so as to prevent the material from leaking from the lower opening of the transfer box 31;

[0133] The second driving unit 44 is installed on the frame 1 and is in driving connection with the bending box 41, and is used for driving the bending box 41 to move back and forth in the X-axis direction.

[0134] The pre-pressing mechanism 5 is arranged on one side of the feeding bin 2 in the positive direction of the X-axis. Figure 11 As shown, the specific structure includes:

[0135] A first crossbeam 51 is arranged above the transfer mechanism 3;

[0136] A plurality of pre-pressing units 52 are vertically arranged and installed at intervals along the Y-axis direction on the bottom surface of the first cross beam 51 and correspond one to one with the material boxes 3a;

[0137] The third driving unit 53 is installed on the frame 1 and is in driving connection with the first crossbeam 51 , and is used for driving the first crossbeam 51 to reciprocate in the vertical direction.

[0138] The buckling mechanism 6 is arranged on one side of the pre-pressing mechanism 5 in the positive direction of the X axis. Figure 12 and Figure 13 As shown, the specific structure includes:

[0139] The second cross beam 61 is arranged above the bending mechanism 4;

[0140] A plurality of buckling units 62 are vertically arranged and are installed at intervals along the Y-axis direction on the bottom surface of the second cross beam 61, and correspond to the bending boxes 4a one by one;

[0141] The fourth driving unit 63 is installed on the frame 1 and is in transmission connection with the second cross beam 61, and is used to drive the second cross beam 61 to reciprocate in the vertical direction.

[0142] The backing plate 7 is horizontally arranged below the forming box 41, and the top surface thereof can be in close contact with the bottom surface of the forming box 41; a protective plate is installed on the bottom surface of the backing plate 7, and the protective plate is supported on a plurality of support beams arranged along the Y-axis direction in the frame 1, so as to improve the bearing capacity and ensure the plugging effect.

[0143] The fifth driving unit 8 is installed on the frame 1 and is in transmission connection with the backing plate 7, and is used to drive the backing plate 7 to reciprocate in the X-axis direction.

Preferably, it is a conveyor belt type, but is not limited thereto, and no specific limitation is made.

[0145] A plurality of square pipes are arranged at intervals along the X-axis direction, and the axes thereof are parallel to the Y-axis direction, and are installed on the frame 1 and are used to support the backing plate 7.

[0146] It should be noted that, as Figure 14 shown, directly below the feeding bin 2 is the receiving position, directly below the pre-pressing mechanism 5 is the pre-pressing position, and directly below the buckling mechanism 6 is the buckling position; during operation, the transfer box 31 reciprocates step by step between the receiving position and the pre-pressing position, the forming box 41 reciprocates step by step between the pre-pressing position and the buckling position, and one end of the backing plate 7 in the positive X-axis direction reciprocates step by step between the pre-pressing position and the buckling position.

[0147] Preferably, a plurality of limit bolts are further installed on the frame 1 to limit the movement strokes of the transfer box 31, the forming box 41 and the backing plate 7, and ensure that they can accurately reach the receiving position, the pre-pressing position or the buckling position, thereby improving the movement accuracy.

[0148] The working process of the above technical solution is specifically as follows:

[0149] S1. The curved material is input from the upper opening of the feeding bin 2 so that a large amount of it is temporarily stored in the feeding bin 2.

[0150] S2. The first driving unit 34 is used to drive the transfer box 31 to be in the receiving position. Then, the curved material in the feeding bin 2 falls into the respective material boxes 3a in the transfer box 31 through the lower opening. And because the second baffle 43 blocks at the bottom surface at this time, the curved material in the material box 3a will not fall downward.

[0151] S3. Drive the transfer box 31 to move to the pre-pressing position through the first driving unit 34, and drive the bending box 41 to move to the pre-pressing position through the second driving unit 44. Then the transfer box 31 and the bending box 41 are aligned, so that each material box 3a and the bending box 4a correspond to each other. And due to the shielding of the lower opening of the feeding bin 2 by the first baffle 33, the curved material in the feeding bin 2 no longer continues to fall. Due to the shielding of the bottom surface of the bending box 41 by the backing plate 7, the curved material in the bending box 4a will not fall downward.

[0152] S4. Drive the first cross beam 51 to move downward through the third driving unit 53. The first cross beam 51 drives each pre-pressing unit 52 to descend synchronously. Each pre-pressing unit 52 extends into the material box 3a one by one, forcibly pushes the curved material in the material box 3a into the bending box 4a, and performs preliminary pressing and forming, and then rises and resets after the pressing is completed.

[0153] S5. Drive the transfer box 31 to return to the material receiving position through the first driving unit 34, so that it performs the operation of S2 above again. At the same time, drive the bending box 41 to move to the bending position through the second driving unit 44, and drive the backing plate 7 to be at the bending position at one end in the positive X-axis direction through the fifth driving unit 8, so that the backing plate 7 keeps shielding the bottom surface of the bending box 41 at the bending position to prevent the curved material in the bending box 4a from falling downward.
