[0037] like Figure 1 As shown, the rotary table 2 is mounted on the frame 1 and is controlled by a stepper motor to perform a rotation gap motion. A plurality of forming dies 3 are arranged and evenly distributed in a circle on the rotary table 2, and serve as a forming die for the pointed-top steamed corn bread, and are used for extrusion and shaping of the pointed-top steamed corn bread.

[0038] like Figure 2As shown, the forming mold 3 includes a fixed half mold 31 and a movable half mold 32. The movable half mold 32 is fixed to the fixed half mold 31 through a movable rotating shaft 33. The fixed half mold 31 and the movable half mold 32 are both provided with a semi-pointed bottom mold hole 34 penetrating the upper end surface and the front end surface thereof. The two semi-pointed bottom mold holes 34 of the fixed half mold 31 and the movable half mold 32 are combined to form a forming hole for the pointed-top steamed corn bread. The movable half mold 32 can be rotated by controlling the movable rotating shaft 33, so that the formed pointed-top steamed corn bread in the two semi-pointed bottom mold holes 34 can be easily taken out.

[0039] like Figure 1 As shown, five forming dies 3 can be provided, and the kneading mechanism 4, shaping mechanism 5, preforming mechanism 7, forming cup dropping mechanism 8 and cup withdrawing mechanism 9 are sequentially arranged above the five forming dies 3 and are all fixedly mounted on the frame 1. During the stepping rotation of the rotary table 2, the kneading mechanism 4, shaping mechanism 5, preforming mechanism 7, forming cup dropping mechanism 8 and cup withdrawing mechanism 9 sequentially pass through each forming die 3 and realize the production and forming of the pointed-top steamed corn bread of the dough in the forming die 3.

[0040] like Figure 1 As shown, the pinching mechanism 4 is used to divide the dough into portions and drop them into the forming mold 3 in sequence.

[0041] like Figure 1 As shown, the shaping mechanism 5 is arranged above the forming die 3 between the pinching mechanism 4 and the preforming mechanism 7 and is fixedly mounted on the frame 1, and is used to extrude and shape the dough in the forming die 3 to ensure the stability of the shape of the dough.

[0042] like Figure 3As shown, the preforming mechanism 7 is used to pre-extrude the dough falling into the forming die 3 into the preliminary shape of the pointed-top steamed corn bread. The preforming mechanism 7 includes a preforming fixed frame 71, a preforming cylinder 72, a preforming connecting rod 73, a preforming punch 74, a buffer head 75 and a preforming compression spring 76. The preforming fixed frame 71 is installed on the frame 1, the preforming cylinder 72 is vertically installed on the preforming fixed frame 71, the upper end of the preforming connecting rod 73 is fixed on the output shaft of the preforming cylinder 72 and is controlled to be extended and retracted, the preforming punch 74 is installed on the lower end of the preforming connecting rod 73, the buffer head 75 and the preforming compression spring 76 are both sleeved on the preforming connecting rod 73, the upper end of the preforming compression spring 76 is fixed to the outer wall of the preforming fixed frame 71 or the preforming connecting rod 73, and the lower end is fixed to the upper end surface of the buffer head 75. During the operation of the preforming mechanism 7, the preforming cylinder 72 controls its output shaft to extend, and the preforming connecting rod 73 drives the preforming punch 74 and the buffer head 75 to move vertically downward until the buffer head 75 contacts the forming die 3; thereafter, the preforming punch 74 continues to move downward under the action of the preforming cylinder 72 and the preforming connecting rod 73 and falls into the dough in the forming die 3, so that the dough is pre-extruded into the initial shape of a pointed-top steamed corn bread; during the process of the preforming punch 74 extruding the dough, the buffer head 75 moves upward relative to the preforming connecting rod 73, the preforming compression spring 76 is gradually compressed, and the buffer head 75 stops moving relative to the forming die 3 and closes the forming die 3, so that the dough will not be squeezed out of the forming die 3.

[0043] like Figure 1 , 4 As shown in Figure 10, the cup separating and feeding mechanism 6 is installed on the frame 1 on one side of the cup forming and dropping mechanism 8, and is used to separate the stacked cup molds 100 one by one and feed them into the cup forming and dropping mechanism 8.

[0044] like Figure 4-10 As shown, the cup-dispensing and cup-feeding mechanism 6 comprises a base support 61, a plate 62, a cup groove 64, a cup-dispensing device 66, a cup-feeding device 65, and an air block 67. The plate 62 is mounted on the base support 61 through a support rod, the cup groove 64 is mounted above the plate 62 through a support rod, and the end of the cup groove 64 is connected to the cup mold through hole opened on the plate 62. A plurality of cup mold limiting rods 63 are arranged between the end of the cup groove 64 and the plate 62, and the lower ends of the plurality of cup mold limiting rods 63 are evenly distributed on the plate 62 outside the cup mold through hole, and the upper ends thereof are evenly distributed outside the end of the cup groove 64.

[0045] The cup-distributing device 66 includes a trapezoidal plate 664, a grooved plate 665 and a cup-distributing cylinder 666. The grooved plate 665 is provided with a rear large circular hole 6651 and a front waist-shaped hole 6652 which are interconnected. A notch 6641 is provided at the center of the front end of the trapezoidal plate 664. Wedge-shaped components 6642 which are thin at the front and thick at the rear are provided at the front ends of the trapezoidal plate 664 on both sides of the notch 6641. The trapezoidal plate 664 is fixedly installed above the grooved plate 665, and the notch 6641 coincides with the center of the rear large circular hole 6651. The grooved plate 665 is placed directly below the through hole of the cup mold and fixedly installed on the telescopic output shaft of the cup-distributing cylinder 666. The cup-distributing cylinder 666 is installed on the base bracket 61.

[0046] There is a certain gap between two adjacent cup molds 100 among the several cup molds 100 stacked together in the cup groove 64, and there is a distance of about 6 mm between the cup brims of the two cup molds 100. In the normal non-cup separation state, several cup molds 100 fall into the front waist-shaped hole 6652 engaged with the groove plate 665. When the cups are to be separated, the cup separation cylinder 666 controls the trapezoidal plate 664 and the groove plate 665 to extend forward, and the front end wedge-shaped component 6642 of the trapezoidal plate 664 is inserted between the two cup brims of the bottom cup mold 100 and the second-to-last cup mold 100, and the bottom cup mold 100 is placed in the large circular hole 6651 on the rear side of the groove plate 665. At this time, the bottom cup mold 100 can be separated from the second-to-last cup mold 100 under the action of external force, thereby achieving the purpose of cup separation.

[0047] The cup-dispensing device 66 further includes a fixed block 661, a second slide rail 662 and a second slider 663. A fixed plate 611 is provided on the base bracket 61. The fixed block 661 is fixed on the fixed plate 611. The second slide rail 662 is fixedly mounted on the fixed block 661. The second slider 663 is mounted on the second slide rail 662. The groove plate 665 is fixedly mounted on the second slider 663. The trapezoidal plate 664, the groove plate 665 and the second slider 663 telescope and slide on the second slide rail 662 together with the telescopic output shaft under the control of the cup-dispensing cylinder 666. The provision of the second slide rail 662 and the second slider 663 can improve the stability of the telescopic movement of the trapezoidal plate 664 and the groove plate 665.

[0048] The gas block 67 is placed below the cup-separating device 66 and fixed on the base bracket 61. The gas block 67 is connected to the negative pressure device through the gas pipe 671. The gas block 67 is provided with a cup-dropping groove which coincides with the center of the through hole of the cup mold. After the bottom cup mold 100 is placed in the large circular hole 6651 at the rear side of the groove plate 665, the gas block 67 generates a negative pressure suction force on the bottom cup mold 100, thereby separating the bottom cup mold 100 from the penultimate cup mold 100.

[0049] The cup delivery device 65 includes a pushing cylinder 651 and a pushing fork plate 652. The pushing cylinder 651 is perpendicular to the cup separation cylinder 666 and is fixed on the base bracket 61. The front end of the pushing fork plate 652 is set to a U shape and is placed under the groove plate 665. The rear end of the pushing fork plate 652 is fixed on the telescopic output shaft of the pushing cylinder 651. Before the bottom cup mold 100 is separated from the penultimate cup mold 100, the pushing cylinder 651 controls the pushing fork plate 652 to extend to just below the large circular hole 6651 on the rear side of the grooved plate 665, and waits for the bottom cup mold 100 to fall onto the pushing fork plate 652 under the negative pressure of the gas block 67; or after the bottom cup mold 100 falls into the cup dropping groove of the gas block 67 under the negative pressure of the gas block 67, the pushing cylinder 651 controls the pushing fork plate 652 to extend and push this cup mold 100 to the forming cup dropping mechanism 8 of the adjacent workstation, thereby realizing the separation and feeding of the overlapping cup molds 100 one by one.

[0050] The cup delivery device 65 further includes a slider 653 and a slide rail 654. The slide rail 654 is fixedly mounted on the fixed plate 611, the slider 653 is mounted on the slide rail 654, the telescopic output shaft of the push cylinder 651 is fixedly mounted on the slider 653, and the push fork plate 652 and the slider 653 telescopically slide on the slide rail 654 together with the telescopic output shaft under the control of the push cylinder 651. The arrangement of the slider 653 and the slide rail 654 can improve the stability of the telescopic movement of the push fork plate 652.

[0051] like Figure 1 , 11 As shown, the cup forming mechanism 8 is used to insert the tip of the lower end of the cup mold 100 into the dough of the forming mold 3, so that the dough is squeezed into the final shape of the pointed-top steamed corn bread and formed into the pointed-top steamed corn bread.

[0052] Among them, the forming cup dropping mechanism 8 includes a forming cup dropping fixing seat 81, a forming cup dropping cylinder 82, a cup dropping punch 83, a left cup adding plate 84, and a right cup adding plate 85. The forming cup dropping fixing seat 81 is installed on the frame 1, and the forming cup dropping cylinder 82 is vertically installed on the forming cup dropping fixing seat 81. A vertical forming cup dropping connecting rod 821 is installed on the output shaft at the lower end of the forming cup dropping cylinder 82. The cup dropping punch 83 is installed at the lower end of the forming cup dropping connecting rod 821 and is controlled by the forming cup dropping cylinder 82 to perform telescopic movement in the vertical direction.

[0053] The left cup-adding plate 84 and the right cup-adding plate 85 are respectively arranged on both sides of the cup-dropping punch 83 and are fixedly installed in the side end surface of the forming cup-dropping fixing seat 81 through the cup-adding plate rotating shaft 86; the upper end surfaces of the left cup-adding plate 84 and the right cup-adding plate 85 are both provided with connecting ear plates or fixing pins, and a forming cup-dropping tension spring 87 is installed between the two connecting ear plates or fixing pins. The cup-dropping cylinder 82 can drive the cup-dropping punch 83 to move up and down. When the cup-dropping punch 83 moves downward, it falls downward between the left cup-adding plate 84 and the right cup-adding plate 85; at the same time, the pushing fork plate 652 of the cup-distributing and cup-feeding mechanism 6 pushes and squeezes a single cup mold 100 between the left cup-adding plate 84 and the right cup-adding plate 85, and the left cup-adding plate 84 and the right cup-adding plate 85 rotate and open under the squeezing of the cup-dropping punch 83 and the cup mold 100; at this time, the forming cup-dropping tension spring 87 is in a gradually stretched state. When the cup-dropping punch 83 moves upward, it moves upward and gradually disengages from between the left cup-adding plate 84 and the right cup-adding plate 85 , and the forming cup-dropping tension spring 87 in a stretched state gradually retracts and causes the left cup-adding plate 84 and the right cup-adding plate 85 to rotate and close together.

[0054] During the operation of the forming cup dropping mechanism 8, first, the push fork plate 652 of the cup-splitting and cup-feeding mechanism 6 directly pushes and squeezes the single cup mold 100 between the left cup-adding plate 84 and the right cup-adding plate 85 to clamp it; or the cup-dropping punch 83 moves downward under the control of the cup-dropping cylinder 82 and squeezes it between the left cup-adding plate 84 and the right cup-adding plate 85, so that the left cup-adding plate 84 and the right cup-adding plate 85 rotate and slightly open, and the push fork plate 652 of the cup-splitting and cup-feeding mechanism 6 pushes and squeezes the single cup mold 100 between the left cup-adding plate 84 and the right cup-adding plate 85 to clamp it; at this time, the forming cup-dropping tension spring 87 is in a gradually stretched state. Then, the forming cup-dropping cylinder 82 controls the cup-dropping punch 83 to drop and push the cup mold 100 between the left cup-adding plate 84 and the right cup-adding plate 85 into the dough of the forming die 3, so that the dough is squeezed into the final shape of the pointed-top steamed corn bread and formed into the pointed-top steamed corn bread. Finally, the forming cup dropping cylinder 82 controls the cup dropping punch 83 to rise and separate from the left cup adding plate 84 and the right cup adding plate 85, and the forming cup dropping tension spring 87 in the stretched state retracts and causes the left cup adding plate 84 and the right cup adding plate 85 to rotate and close together.

[0055] like Figure 1 , 12 As shown, the cup-retracting mechanism 9 is used to separate the cup mold 100 and the formed pointed-top steamed corn bread and transport them to the next process.
