Description

Technical Field

[0001] The invention relates to the field of steamed bun making machines, in particular to an automatic steamed bun making machine with pleats for stuffing. Background Art

[0002] Currently, the most common steamed bun making machines on the market can be divided into extrusion and rolling types based on the wrapping method. The extrusion type steamed bun making principle is to use a dough hopper and a filling hopper. The dough at the outer outlet is squeezed by an auger, and then the dough is cut by a knife. The upper part of the cross section is patterned, and the lower part is flattened by a flattening device to form the bottom of the bun.

[0003] The rolling-type bun machine places the dough sheet on the dough pulley, passes it through three thickness-adjustable dough pressing wheels, gradually pats and rolls it thin, and presses out standard dough that meets the needs. Then, the filling feeder is turned on, and the discharge nozzle specifications required for the product are selected. The dough is wrapped with the filling and rolled into long strips through the winding wheel, auxiliary winding wheel and other devices. The pinching device is turned on and the pinching length is set to produce products of the required specifications.

[0004] The advantage of the extrusion type bun machine is that the buns made are flat and beautiful in appearance. The buns made by the calendering type bun machine can have wrinkles that imitate handmade ones, but the wrinkles are formed by the sliding of the knife. The pattern of the stuffed product is shallow after steaming, which is quite different from the wrinkles made by hand. Summary of the Invention

DETAILED DESCRIPTION

[0021] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0022] Example 1 like Figures 1 to 20As shown, an automatic steamed bun machine with pleated stuffing includes a frame 1, a feeding belt telescopic component 2 and a discharging conveying component 3 are arranged on the frame 1, and a stuffing pressing component 4, an indentation component 5, a gathering component 6, a sealing component 7 and a support plate lifting component 8 are arranged between the feeding belt telescopic component 2 and the discharging conveying component 3 from top to bottom. The support plate lifting component 8 includes a support plate 14, and the stuffing pressing component 4 includes a skin suction plate 9 and a pre-pressing ring. The skin suction plate 9 adopts negative pressure to absorb the dough. Specifically, a negative pressure cavity is provided in the skin suction plate 9, and a plurality of negative pressure holes communicating with the negative pressure cavity are opened at the bottom of the skin suction plate 9. The skin suction plate 9 is connected to the negative pressure cavity. The negative pressure equipment is connected through a pipeline. The skin suction plate 9, the pre-pressing ring, and the supporting plate 14 all have the freedom to move in the vertical direction. A plurality of pre-pressing sheets 10 are fixed to the bottom of the pre-pressing ring along its own circumferential direction. The indentation component 5 includes a rotating disk 11 and an indentation sheet 12. The rotating disk 11 is hollow. The inner ring of the rotating disk 11 is provided with a plurality of indentation sheets 12 along its own circumferential direction. The indentation sheet 12 has the freedom to move radially along the rotating disk 11. The retracting component 6 includes a plurality of circumferentially arrayed skin connecting sheets 13. An annular space for the supporting plate 14 to move is formed between the plurality of skin connecting sheets 13. The skin connecting sheets 13 have a hinge point with a horizontal axis.The stuffing pressing component 4 is used to place the dough on the feed belt telescopic component 2 on the dough connecting piece 13. Several dough connecting pieces 13 and several pre-pressing pieces 10 are staggered in sequence to form a gap fit, which is used to pre-form indentations on the dough. The dough connecting piece 13 deflects toward the annular space at the hinge point to make the dough gather into an upright state, and cooperates with the indentation piece 12 to form folds around the dough, and finally seals it through the sealing component 7 to form wrinkled buns. The dough is prefabricated in advance, and the dough preferably adopts a circular structure that is thick in the middle and thin around the edges. The dough is transported to the working position of the stuffing pressing component 4 through the feed belt telescopic component 2, and the skin suction plate 9 moves downward to absorb the dough under negative pressure, and then the skin suction plate 9 moves upward to reset the feed belt telescopic component 2. At this time, the indentation piece 12 of the indentation component 5 is in a fully open state, and the skin connecting piece 13 of the gathering component 6 is in an open skin-connecting state, and then the support plate 14 moves upward to catch the dough placed down by the skin suction plate 9. At this time, the middle part of the dough passes through the support plate 14 is supported, and the dough skin is supported by the dough connecting piece 13 on all sides. Then, the pre-pressing ring drives the pre-pressing piece 10 to move downward, squeezing through the gap between the pre-pressing piece 10 and the dough connecting piece 13 to form indentations on the four sides of the dough skin. After the filling is injected into the dough skin, the filling pressing component 4 is reset upward, and then the dough connecting piece 13 rotates, causing the dough connecting piece 13 to deflect toward the center of the dough skin, thereby gathering the four sides of the dough skin into an upright state. Then, the indentation piece 12 moves toward the center of the circle of the rotating disk 11, squeezing the indentations to form wrinkles. Finally, the dough skin is sealed by the sealing component 7, and the production of wrinkled buns is completed. Then, the supporting plate 14 drives the finished buns to move downward, and finally, the buns are sent out by the material conveying component 3, completing the automated production of wrinkled buns. Each component is reset and the above operation is repeated to realize batch production of buns. The wrinkles are formed by indentation, which is closer to the effect of traditional handmade products. Even after the stuffed products are steamed, the wrinkles will not rebound.

The feeding mounting plate 81 is provided with a belt driving pulley 89. The output shaft of the motor 88 is connected to the belt driving pulley 89. The belt driving pulley 89 is connected to the rotating shaft through the belt 90. The dough is placed on the belt 90 and the dough is moved by the motor. 88 drives the belt driving wheel 89 to rotate, and the belt driving wheel 89 drives the belt 90 to move, and the dough is transported to the filling pressing component 4 through the belt 90. When the dough is transported to the end of the movable plate 84, the conveying stops, and the feeding servo motor 87 drives the synchronous pulley 82 to rotate, thereby the synchronous belt 85 is activated, and the synchronous belt 85 drives the movable plate 84 to move on the feeding guide rail 83 through the driving plate 86, so that the end of the movable plate 84 moves to the right below the filling pressing component 4, so that the skin suction plate 9 moves downward to smoothly absorb the dough. When the skin suction plate 9 absorbs the dough and moves upward to separate from the belt 90, the feeding servo motor 87 reverses and drives the movable plate 84 to reset, so that the skin suction plate 9 can move downward to place the dough on the support plate 14 and the skin connecting piece 13. During specific implementation, a fiber optic electric eye 98 is installed on the frame 1. The fiber optic electric eye 98 detects whether the dough on the belt 90 is transported to the end of the movable plate 84. When the fiber optic electric eye 98 detects that the dough is in place, the movable plate 84 moves at a fixed length to transport the dough to the bottom of the skin suction plate 9, so that the dough can be accurately loaded.
