[0027] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0028] like Figure 1-10As shown, a shortbread baking device of the present invention comprises a baking device body 1, wherein two linearly distributed rotating rings 10 are rotatably mounted inside the baking device body 1, and the side walls of the two rotating rings 10 are provided with a plurality of circumferentially distributed rotating grooves 11, and circular rings 12 are rotatably mounted in the plurality of rotating grooves 11, and the plurality of circular rings 12 are provided with square openings 13, and a plurality of baking trays 14 are installed inside the baking device body 1, and the plurality of baking trays 14 located on the lower side are rotatably mounted between the two rotating rings 10, and the front and rear sides of the plurality of baking trays 14 are fixedly provided with semicircular rods 15 matching the circular rings 12, and the inner walls of the two rotating rings 10 are provided with a plurality of circumferentially distributed tooth grooves 16, and the baking device body 1 is rotatably mounted inside the baking device body 1 A circular shaft 17 is movable and fixedly provided with two toothed discs 18 meshing with a plurality of tooth grooves 16. A first motor 19 is installed at the rear side of the baking device body 1. The output shaft of the first motor 19 is transmission-connected with the circular shaft 17. A lifting plate 20 is slidingly installed inside the baking device body 1. An electric telescopic rod 21 is fixedly installed at the upper side of the baking device body 1. The output end of the electric telescopic rod 21 is fixedly connected with the lifting plate 20. The baking tray 14 located at the uppermost side is rotationally installed at the lower side of the lifting plate 20. The baking tray 14 located at the uppermost side is symmetrically arranged with the adjacent baking tray 14 up and down. A flip assembly matching with the baking tray 14 at the uppermost side and the adjacent baking tray 14 is provided at the rear side of the lifting plate 20.

[0029] When the present invention is used, the user first opens the baking device body 1, installs the baking tray 14 containing the shortbread dough between the two rotating rings 10 in sequence, then closes the baking device body 1, starts the baking device body 1 to bake, and bakes the shortbread dough on the upper side of the inner baking tray 14. At the same time, the first motor 19 is synchronously started, and the output shaft of the first motor 19 drives the circular shaft 17 to rotate, and the circular shaft 17 synchronously drives the two toothed discs 18 to rotate synchronously, and the two toothed discs 18 synchronously drive the two rotating rings 10 to rotate, and the two rotating rings 10 synchronously drive the plurality of baking trays 14 to rotate. During the rotation of the plurality of baking trays 14, the circular ring 12 synchronously rotates in the rotating groove 11 during the rotation driven by the rotating ring 10, and the circular ring 12 drives the baking tray 14 to rotate synchronously through the two semicircular rods 15, ensuring that during the rotation of the plurality of baking trays 14 driven by the rotating ring 10, the baking tray 14 always rotates upward, and the plurality of shortbread dough on the upper side of the baking tray 14 is evenly baked, thereby ensuring the quality of the product;

[0030] During the use of the present invention, after the baking device body 1 bakes the shortbread dough on the upper side of the baking tray 14 for a period of time, the electric telescopic rod 21 drives the lifting plate 20 to descend, so that the baking tray 14 installed on the lower side of the lifting plate 20 is in contact with the baking tray 14 on the uppermost side of the two rotating rings 10, and the flipping assembly drives the two baking trays 14 to rotate synchronously to turn over the shortbread dough, and the operation is performed in sequence to flip one side of several baking trays 14 between the two rotating rings 10 to ensure that all the shortbread dough is turned over, and there is no need to manually open the baking device body 1 for operation, thereby ensuring the production quality of the shortbread;

[0031] The present invention drives the lifting plate to descend by an electric telescopic rod, so that the uppermost baking tray is fitted with the adjacent baking tray, and then the two fitted baking trays are rotated synchronously by a flipping assembly, so that the shortbread in the baking tray is turned over, and when the two rotating rings are continuously rotated, the shortbread in each baking tray is turned over in turn, which is convenient for continuous baking of the shortbread and reduces the labor intensity of manual labor.

[0032] The flip assembly includes a plurality of semicircular rods 15, each of which is fixed with a half gear 25 at one end away from the baking tray 14. A rotating shaft 26 is rotatably mounted on the rear side wall of the lifting plate 20. A gear 27 matching the half gear 25 is concentrically fixedly mounted on the rotating shaft 26. A first bevel gear 28 is concentrically fixedly mounted on the rotating shaft 26. A vertical shaft 29 is rotatably mounted in the baking device body 1. A second bevel gear 30 meshing with the first bevel gear 28 is concentrically mounted on the vertical shaft 28. A plurality of circumferentially distributed card slots 31 are opened on the side wall of the vertical shaft 29. A card block matching the card slot 31 is fixedly mounted on the inner wall of the second bevel gear 30. A second motor 32 is mounted on the upper side of the baking device body 1. The output shaft of the second motor 32 is drivingly connected to the vertical shaft 29.

[0033] During use of the present invention, when the baking tray 14 needs to be turned over, the lifting plate 20 drives the lower baking tray 14 to move downward, and synchronously drives the second bevel gear 30 to slide along the vertical shaft 29. After the two opposite baking trays 14 are attached together, the second motor 32 drives the vertical shaft 29 to rotate, and the vertical shaft 29 drives the second bevel gear 30 to rotate through the slot 31 and the block, and the second bevel gear 30 synchronously drives the first bevel gear 28 to rotate, and the first bevel gear 20 drives the gear 27 to rotate through the rotating shaft 26, and the two semicircular rods 1 After the two half gears 25 are fitted together, the gear 27 rotates again, driving the two half gears 25 to rotate, thereby driving the semicircular rod 15 and the baking tray 14 to rotate synchronously, so that the shortbread dough in the baking tray 14 is turned over and falls into the baking tray 14 under the lifting plate 20, and the lifting plate 20 drives the turned baking tray 14 to move upward, and the two rotating rings 10 synchronously drive the plurality of baking trays 14 to continue rotating, and turn over the plurality of baking trays 14 in turn, so that the shortbread is baked more evenly and the baking efficiency is higher.

[0034] The two rotating rings 10 are each provided with a plurality of limit members matching the circular ring 12, the limit members comprising two symmetrically distributed arc grooves 35 opened inside the rotating ring 10, the two arc grooves 35 are respectively opened on the left and right sides of the rotating groove 11, arc blocks 36 are slidably mounted in the two arc grooves 35, arc springs 37 are fixedly mounted between the two arc blocks 36 and the side walls of the arc grooves 35, two arc openings communicating with the arc grooves 35 are opened on the upper sides of the two rotating rings 10, arc blocks 38 matching the arc openings are fixedly mounted on the side walls of the two arc blocks 36, four push plates 39 symmetrically distributed on the left and right sides are slidably mounted on the lower side of the lifting plate 20, the four push plates 39 are respectively matched with the four arc blocks 38, and first springs 40 are fixedly mounted between the outer side walls of the four push plates 39 and the side walls of the lifting plate 20;

[0035] When the present invention is in normal use and the baking tray 14 does not need to be turned over, the two adjacent push plates 39 are brought closer to each other under the elastic action of the first spring 40, and the two arc blocks 36 extend out of the arc groove 35 under the elastic action of the arc spring 37, and the two adjacent arc blocks 26 abut against each other, so that the rotating groove 11 forms a closed circular groove, ensuring the normal rotation of the ring 12;

[0036] During the use of the present invention, when it is necessary to flip the baking tray 14, the lifting plate 20 drives the baking tray 14 to descend, and at the same time drives the four push plates 39 to descend synchronously. Driven by the lifting plate 20, the four push plates 39 first abut against the arc-shaped shifting block 38, and push the arc-shaped shifting block 38 to move along the arc-shaped opening. The arc-shaped shifting block 38 synchronously drives the arc-shaped block 36 to move, so that the arc-shaped spring 37 is compressed. After the arc-shaped block 36 is completely retracted into the arc-shaped groove 35, the lifting plate 20 drives the semicircular rods 15 on the front and rear sides of the baking tray 14 to move into the rotating groove 11, and extend into the circular ring 12 through the square opening 13, abut against the baking tray 14 on the lower side, and then the two fitted baking trays 14 are synchronously flipped through the flipping assembly, so as to realize automatic flipping of the shortbread on the upper side of the baking tray 14 and ensure the baking quality of the shortbread.

[0037] A control member matching the uppermost baking tray 14 is provided on the lower side of the lifting plate 20. The control member includes four round rods 45 symmetrically distributed and rotatably assembled on the lower side of the lifting plate 20. Conical blocks 46 are fixedly disposed concentrically on the lower sides of the four round rods 45. Vertical grooves 47 matching the round rods 45 are provided on the side walls of the semi-circular rods 15. The side walls of the semi-circular rods 15 are processed into grooves.

[0038] When the present invention is used, it is not necessary to flip the baking tray 14. Under the pull of the four round rods 45 and the conical block 46, the inverted baking tray 14 is stably installed on the lower side of the lifting plate 20. The installation process is simple and easy to operate.

[0039] During the use of the present invention, when the baking tray 14 needs to be turned over, the lifting plate 20 drives the inverted baking tray 14 to descend. After the two baking trays 14 are attached, the lifting plate 20 drives the four round rods 45 and the conical block 46 to descend synchronously, and the lower side of the conical block 46 abuts against the semicircular rod 15 of the baking tray 14. The conical block 46 drives the round rod 45 to rotate, so that the side wall of the round rod 45 abuts against the vertical groove 47 of the side wall of the lower semicircular rod 15. The flipping assembly drives the two attached baking trays 14 to close. After the plate 14 rotates, the lifting plate 20 moves upward, driving the four round rods 45 to move upward synchronously. When the conical block 46 moves to the groove between the two semicircular rods 15, the round rods 45 approach each other, so that the conical block 46 is inserted into the groove. The conical block 46 abuts against the lower side wall of the upper semicircular rod 15. Under the continuous movement of the lifting plate 20, the inverted baking tray 14 on the upper side is pulled upward to facilitate the fit with the next rotating baking tray 14, ensuring that all the shortbreads are turned over.

[0040] Long grooves 50 are formed on the left and right side walls of the rings 12, long blocks 51 are slidably mounted in the long grooves 50, second springs 52 are fixed between the side walls of the long blocks 51 and the side walls of the long grooves 50, and the side walls of the long blocks 51 away from the adjacent semicircular rods 15 are processed into inclined surfaces;

[0041] During use of the present invention, under the elastic action of the second spring 52, the long block 51 extends out of the long slot 50, and the side wall of the long block 51 abuts against the side wall of the semicircular rod 15, limiting the semicircular rod 15 to prevent the semicircular rod 15 from rotating independently, ensuring that the baking tray 14 always remains facing upward. When the baking tray 14 is turned over, the lifting plate 20 drives the lower baking tray 14 to descend, and the semicircular rods 15 on the front and rear sides of the inverted baking tray 14 abut against the inclined surfaces on the upper sides of the long blocks 51 on both sides, thereby pushing the long block 51 to move into the long slot 50, ensuring the fit of the two baking trays 14 and ensuring the smooth turning of the baking tray 14.

[0042] A plurality of linearly distributed vertical plates 55 are fixedly provided on the lower side of the lifting plate 20, and the lower sides of the plurality of vertical plates 55 are all provided with arc surfaces matching the semicircular rods 15; when the lifting plate 20 drives the inverted baking trays 14 to descend, the vertical plates 55 push the semicircular rods 15 to make the two opposite baking trays 14 fit smoothly, and at the same time, the lower side walls of the vertical plates 55 abut against the side walls of the square opening 13 of the circular ring 12 to prevent the circular ring 12 from rotating autonomously, thereby ensuring the smooth flipping of the two baking trays 14.

[0043] Several annular grooves matching the rotating grooves 11 are provided in the two rotating rings 10, and the several annular grooves are interconnected with the adjacent arc grooves 35. Annular blocks 57 matching the annular grooves are fixedly provided on the side walls of the several circular rings 12; the rotation of the circular rings 12 is limited to prevent the circular rings 12 from sliding forward and backward, thereby ensuring the smooth use of the device.

[0044] The side walls of the baking trays 14 are provided with a plurality of placement grooves 60 which are distributed linearly; the shortbread dough is placed separately, which is convenient for turning the shortbread dough over, avoiding the mixing of the shortbreads, and placing the crumbs inside the baking device body 1, thereby improving the convenience of use of the device.

[0045] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention.
