Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.

[0022] Please also read Figures 1 to 7, the toast shaping system provided by the present invention is now described. The toast shaping system comprises a frame 1 and a feeding conveyor belt 2, a shaping conveyor belt 3 and a discharging conveyor belt 4 connected to the frame 1 in sequence, a rubbing roller group 21 and a sheeting roller group 22 are arranged on the feeding conveyor belt 2 in sequence, the rubbing roller group 21 is used to squeeze the dough from both sides to form a strip-shaped dough blank, and the sheeting roller group 22 is used to squeeze the strip-shaped dough blank from the upper and lower sides to form a dough sheet, a rolling plate 5 and a finishing device located at the rear side of the rolling plate 5 are arranged on the shaping conveyor belt 3, the rolling plate 5 can cooperate with the shaping conveyor belt 3 to roll up the dough sheet and form a dough roll, the finishing device comprises a slitting knife group 6 and a reversing assembly 8 arranged at intervals along the front and rear directions, the slitting knife group 6 extends along the front and rear directions and is used to cut the dough roll into dough blocks, and the reversing assembly 8 is used to change the direction of the dough block.

[0023] Compared with the prior art, the toast shaping system provided in the present embodiment utilizes the strip rolling roller group 21 and the sheet rolling roller group 22 to shape the dough into strip dough blanks and dough sheets in turn, and uses the rolling plate 5 to roll and compact the dough sheets. Finally, the dough roll is cut by the cutting knife group 6 of the sorting device to make it into dough blocks, which are then reversed by the reversing component 8 to facilitate the separation of two adjacent toast blocks after the subsequent toast forming, thereby improving the convenience of customer operation and also improving the layering and aesthetic appearance of the toast.

[0024] In this embodiment, the dough is fed from the feeding conveyor belt 2, and is first rolled into strips by the rolling roller group 21. This process step not only has the function of shaping the dough, but most importantly, it can guide the dough to the central axis of the feeding conveyor belt 2, so as to improve the position accuracy of subsequent dough sheets and dough rolls, and improve the overall molding quality of subsequent products.

[0025] After the dough is rolled and formed by means of the rolling plate 5, the rolled dough is first cut by the slitting knife group 6, and then the dough blocks are reversed by the reversing component 8, so that the main axis of the dough block during the rolling process is perpendicular to the length direction of the toast, avoiding external defects caused by uneven fabric at the end, making the external shape of the toast more beautiful, and more importantly, it can also separate two adjacent toast blocks, which helps to improve the convenience of eating and enhance the customer's dining experience.

[0026] For the convenience of description, the direction in which the upper block of the rack 1 moves is defined as the front side, the direction in which the surface block moves away is defined as the rear side, and the direction perpendicular to the front-rear direction is defined as the lateral direction of the rack 1, that is, the left-right direction.

[0027] In one possible implementation, see Figures 1 to 7A width limiting component 51 for guiding the surface 84 to be rolled into between the rolling plate 5 and the shaping conveyor belt 3 is provided on the frame 1. The width limiting component 51 includes two adjusting pipe shafts 52 and two width limiting strips 53. The two adjusting pipe shafts 52 are respectively arranged perpendicular to the front-to-back direction and are located one-to-one at the front and rear ends of the rolling plate 5. The two width limiting strips 53 are respectively arranged along the front-to-back direction and are located one-to-one at the left and right sides of the rolling plate 5. A first gap is provided between the bottom surface of the width limiting strip 53 and the top surface of the shaping conveyor belt 3, and the two width limiting strips 53 can approach each other or move away from each other.

[0028] In the present embodiment, when the rolling plate 5 is used to form the dough roll, in order to avoid the problem of asymmetry of the edges on both sides of the dough roll, a limited width component 51 is also connected to the frame 1, and a first gap is provided between the limited width component 51 and the shaping conveyor belt 3, so as to avoid position interference with the shaping conveyor belt 3 and ensure the stable operation of the shaping conveyor belt 3.

[0029] Two adjusting pipe shafts 52 are respectively connected to the frame 1 and are respectively arranged across the shaping conveyor belt 3. The two ends of the width limiting strip 53 are respectively connected to the two adjusting pipe shafts 52 in a one-to-one correspondence, and are erected above the shaping conveyor belt 3. The two width limiting strips 53 are used to limit the positions of the two ends of the dough roll to avoid the problem of the dough roll shifting to one side during the rolling process, thereby ensuring the quality of the dough roll rolling. The two adjusting pipe shafts 52 can install the two ends of the width limiting strip 53 to ensure that the width limiting strip 53 is suspended above the shaping conveyor belt 3, and there is a gap between the width limiting strip 53 and the shaping conveyor belt 3.

[0030] Furthermore, during the toast shaping process, a material spreading structure can be provided. The material spreading structure can be set at the position of the cutting knife group 6. A small amount of water mist is first sprayed onto the surface of the toast through the spray head. Then, sesame and other auxiliary materials are sprinkled onto the surface of the toast as the toast moves forward. Finally, the auxiliary materials are fixed to the surface of the toast through the compaction structure to meet the need for the auxiliary materials to adhere to the surface of the toast.

[0031] For some examples, see Figures 1 to 7 A width adjustment component 54 for adjusting the spacing between the two width limiting strips 53 is provided on the frame 1. The width adjustment component 54 includes a bidirectional lead screw 55 and a nut seat 56. The bidirectional lead screw 55 is rotatably connected to the frame 1 and is arranged to penetrate the adjusting tube shaft 52 along the axial direction of the adjusting tube shaft 52. A hand wheel 59 is provided at the outer end of the bidirectional lead screw 55. A threaded sleeve 561 of the nut seat 56 is arranged on the bidirectional lead screw 55 and is arranged to penetrate the peripheral wall of the adjusting tube shaft 52 downward. The nut seat 56 can move along the axial direction of the adjusting tube shaft 52 under the drive of the bidirectional lead screw 55, and the lower end of the nut seat 56 is connected to the width limiting strip 53.

[0032] In this embodiment, the spacing between the two width limiting strips 53 is adjusted by the width adjustment component 54 to meet the needs of making and shaping toasts of different specifications, thereby improving the convenience of operation during the production process. Specifically, the cooperation of the bidirectional lead screw 55 and the nut seat 56 is used to achieve the lateral adjustment of the lower width limiting strip 53, thereby changing the spacing between the two width limiting strips 53, so as to be suitable for shaping toasts of different length specifications.

[0033] Specifically, the nut seat 56 includes a threaded sleeve 561 disposed on the outer periphery of the bidirectional lead screw 55 and a connecting arm 562 connected to the bottom of the threaded sleeve 561, and the connecting arm 562 is connected to the width limiting strip 53. When the nut seat 56 is axially translated along the bidirectional lead screw 55, the width limiting strip 53 can be driven to move laterally with the help of the connecting arm 562. The width limiting strip 53 can adopt a hollow structure, and the lower end of the connecting arm 562 is provided with an extension portion 563 that penetrates the side wall of the width limiting strip 53. The extension portion 563 is connected to the top wall of the width limiting strip 53 through a connecting piece, which can effectively simplify the installation structure and ensure the connection strength of the structure.

[0034] For some examples, see Figures 1 to 7 An axially extending scale bar 57 is provided on the adjusting tube shaft 52, and an indicating half ring 58 extending upward along the peripheral wall of the adjusting tube shaft 52 is provided on one side of the nut seat 56. The indicating half ring 58 is used to correspond to the scale bar 57 to indicate the spacing between the two width limiting strips 53.

[0035] In this embodiment, when adjusting the spacing between the two width limiting strips 53, in order to facilitate the control of the gap between the two, a scale bar 57 is provided on the adjustment tube shaft 52, and the indicating semi-ring 58 can be used to intuitively display the spacing between the two width limiting strips 53, so that the spacing meets the length dimension requirements of the dough roll.

[0036] Specifically, the scale bar 57 can be set as the zero scale line starting from the axial middle position of the adjustment tube shaft 52, and the scales on both sides gradually increase. The scale corresponding to the indicating half ring 58 is multiplied by two, so that the spacing between the two width limiting strips 53 is convenient for observation and simple to operate.

[0037] In one possible implementation, see Figures 1 to 7 The slitting knife group 6 includes a knife holder 61 and a plurality of slitting knives 62. The knife holder 61 is connected to the frame 1 and is located above the shaping conveyor belt 3. The slitting knives 62 are connected to the bottom of the knife holder 61 along the front-to-back direction and slide with the knife holder 61 along the up-down direction. The slitting knives 62 and the knife holder 61 are locked by a locking piece. The knife holder 61 has a lower support plate 63, and the lower support plate 63 is penetrated by a clearance hole 64 corresponding to the upper and lower sides of the slitting knives 62. The slitting knife 62 has a slitting blade 65 that gradually extends upward and backward.

[0038] In this embodiment, the slitting knife group 6 is used to cut the entire dough roll into multiple pieces. Generally, an odd number of slitting knives 62 are selected to cut the dough roll into an even number of dough blocks, which is convenient for the subsequent reversing processing of the dough blocks and improves the forming quality of the subsequent dough blocks.

[0039] Specifically, the knife holder 61 is mounted above the shaping conveyor belt 3, and a plurality of slitting knives 62 are connected to the knife holder 61. Each slitting knife 62 is arranged along the front-to-back direction, and can slitting the dough roll with the help of the slitting blade 65 at the front and bottom. Specifically, the width of the dough block is set according to the specifications of the toast, and the slitting knife 62 can be adjusted in the horizontal position on the knife holder 61 and locked by a locking member, so as to improve the adaptability of the slitting knife group 6 and meet the processing requirements of products of different specifications.

[0040] In one possible implementation, see Figures 1 to 7 The frame 1 is also provided with an auxiliary conveyor belt 7 arranged at the outlet end of the discharge conveyor belt 4. The reversing assembly 8 is located above the auxiliary conveyor belt 7. The reversing assembly 8 includes a guide seat 81, a plurality of limit rods 82 and two extrusion rollers 83. The guide seat 81 extends in the front-to-back direction. The limit rods 82 are symmetrically arranged on both sides of the guide seat 81. Both sides of the rear part of the guide seat 81 are provided with guide surfaces 84 for reversing the guide surface 84 blocks. The limit rods 82 are used to limit the lateral position of the noodle block. The main axes of the two extrusion rollers 83 extend in the up-down direction. The two extrusion rollers 83 can cooperate with each other to extrude multiple noodle blocks to form blanks.

[0041] In this embodiment, the reversing component 8 can change the angle of the cut dough blocks so that the main axis direction of the dough blocks (that is, the direction perpendicular to the winding direction of the dough roll) is changed to a ninety-degree angle, that is, the main axis of the dough blocks is changed from the original lateral extension to an extension in the front-to-back direction. At this time, the main axes of multiple dough blocks are all arranged in the front-to-back direction, and the outermost layers of the dough blocks are in contact with each other. Even after the toast is baked, two adjacent dough blocks can be easily separated, thereby improving the convenience of customer operation.

[0042] Specifically, the example of four noodle blocks moving simultaneously is used for explanation. The guide seat 81 is set at the central axis of the shaping conveyor belt 3, and the spacing between the limiting rods 82 on both sides and the adjacent side walls of the guide seat 81 is smaller than the lateral extent of the two noodle blocks. As the four noodle blocks move synchronously, under the extrusion and cooperation of the limiting rods 82 on both sides, the guide seat 81 can guide the front side walls of the two middle noodle blocks to change their angles with the help of the guiding surfaces 84 on both sides, and finally realize the 90-degree reversal of the noodle blocks, which meets the reversal requirements of the noodle blocks and ensures the smooth reversal.

[0043] In one possible implementation, see Figures 1 to 7The rubbing roller group 21 includes two forming rollers 23 whose main shafts are connected to the frame 1 in the up and down directions. A second gap is provided between the lower end surface of the forming roller 23 and the top surface of the feeding conveyor belt 2. The lower parts of the two forming rollers 23 respectively have guiding cones 24 with gradually increasing outer diameters. The guiding cones 24 are used to guide the noodle group 84 to be centered and formed into a strip-shaped noodle blank.

[0044] In this embodiment, the rolling roller group 21 can shape the round dough into a long strip, which is convenient for rolling it into an oblong dough sheet, and then for subsequent rolling and rolling. The guide cone 24 at the bottom of the forming roller 23 can help the dough to be squeezed into a long strip of dough with a circular cross-section, ensuring the smooth passage of the strip dough and preventing the strip dough from sticking and jamming at this position.

[0045] This process step not only has the function of shaping the dough, but most importantly, it can guide the dough to the central axis of the feeding conveyor belt 2, that is, the middle position in the width direction, so as to improve the position accuracy of subsequent dough sheets and dough rolls and improve the overall molding quality of subsequent products.

[0046] In one possible implementation, see Figures 1 to 7 The flaking roller group 22 includes a lower idler roller 25 and an upper pressure roller 26. A pick-up plate 27 located in front of the upper pressure roller 26 and a pick-up roller 28 located in front of the lower idler roller 25 are connected to the frame 1. The rear portion of the pick-up plate 27 is inclined downward toward the side close to the upper pressure roller 26, and is used to guide the surface 84 skin to adjust the upper pressure roller 26. The pick-up roller 28 is located at the lower portion of the lower idler roller 25, and is used to guide the surface 84 skin to separate from the lower idler roller 25.

[0047] In the present embodiment, the sheet rolling roller group 22 adopts a structure combining a lower idler roller 25 and an upper pressing roller 26, which can roll the long strips of dough into sheets. During the rolling process, due to the large rolling force, in order to prevent the dough sheets from adhering to the peripheral wall of the lower idler roller 25 or the upper pressing roller 26, a pick-up plate 27 and a pick-up roller 28 are provided accordingly. The pick-up roller 28 is located at the lower part of the lower idler roller 25, and the pick-up plate 27 has an edge that can contact the peripheral wall of the upper pressing roller 26, so as to facilitate the removal of the dough sheets adhering to the upper pressing roller 26, so that the dough sheets can fall smoothly and be conveyed to the next process step.

[0048] On this basis, the frame 1 is also rotatably connected with a guide roller 29 located in front of and below the material removal roller 28 , and the guide roller 29 is used to guide the surface 84 to fall onto the shaping conveyor belt 3 .

[0049] For some examples, see Figures 1 to 7The discharging end of the discharging conveyor belt 4 is provided with a speed reduction curtain 41, which is used to slow down the speed of the blank so that the blank falls into the toast box. The feeding end of the shaping conveyor belt 3 is provided with an initial rolling curtain 31, which is located on the front side of the pick-up roller 28 and is used to guide the front side edge of the dough sheet 84 to curl backward to form a dough roll.

[0050] In this embodiment, when the discharging conveyor belt 4 drives the blank to move, when the blank moves to its outlet end, there is a forward horizontal speed, and it is difficult to accurately fall into the toast box. By providing a deceleration curtain 41, the blank can be buffered and decelerated at the outlet end of the discharging conveyor belt 4, and the blocking effect of the deceleration curtain 41 can reduce the forward horizontal speed of the blank, so that it can turn and fall into the toast box under the action of its own weight.

[0051] At the same time, the initial rolling curtain 31 arranged on the rear side of the rolling plate 5 can block and limit the front side edge of the dough piece, so that the dough piece initially forms a winding tendency, and then forms a continuous winding tendency under the overall action of the initial rolling curtain 31 above and the shaping conveyor belt 3 below, thereby meeting the forming requirements of the dough roll and facilitating further rolling and pressing processing using the rolling plate 5 later.

[0052] For some examples, see Figures 1 to 7 The rear side edge of the primary rolling curtain 31 is connected with an adjusting cross bar 32, and the frame 1 is provided with two supporting brackets 11 symmetrically located on both sides of the primary rolling curtain 31. The supporting brackets 11 are provided with a plurality of hanging grooves 12 spaced apart along the up and down directions, and the two ends of the adjusting cross bar 32 are respectively hung in the hanging grooves 12 of the two supporting brackets 11 in a one-to-one correspondence.

[0053] In this embodiment, the front side edge of the primary roll curtain 31 is raised in height by adjusting the cross bar 32 to avoid excessive friction between the curled dough roll and the primary roll curtain 31, thereby ensuring that the dough roll can be smoothly conveyed forward for subsequent rolling and pressing steps, further making the dough roll forming more stable and facilitating subsequent slitting and reversing operations on the rolled and pressed dough roll.

[0054] The above-mentioned toast shaping system utilizes the strip rolling roller group 21 and the sheet rolling roller group 22 to shape the dough into strip dough blanks and dough sheets in turn, and uses the rolling plate 5 to roll and compact the dough sheets. Finally, the dough roll is cut by the slitting knife group 6 of the sorting device to make it into dough blocks, which are then reversed by the reversing component 8 to facilitate the separation of two adjacent toast blocks after the subsequent toast forming, thereby improving the convenience of customer operation and also enhancing the layering and aesthetic appearance of the toast.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
