Description

Technical Field

[0001] This invention relates to the field of food production technology, and in particular to a bread production device. Background Technology

[0002] Bread is generally made primarily from wheat flour, with added ingredients and water to form dough. It is then processed through steps such as dividing, shaping, proofing, baking, and cooling. Due to its diverse varieties, good taste, and convenience, it is widely loved. One type of bread has a shape resembling a braided plait. To improve the production efficiency of this type of bread, specialized equipment for producing braided bread was developed.

[0003] Existing woven bread production equipment typically includes a sheeter and sheeting device at the front end for thinning and shaping the dough sheet, a conveyor mechanism for transporting the dough sheet, and a width-limiting and indentation mechanism, a cutting mechanism, and a shaping and weaving mechanism sequentially arranged on the conveyor mechanism. However, existing woven bread production equipment is only suitable for dough sheets under specific conditions, with strict requirements on the dough sheet's hardness, moisture content, and oil content; if these requirements are not met, successful weaving will fail. Common problems include insufficient hardness causing the dough sheet to get stuck on the cutting rollers of the cutting mechanism during cutting; or blockage at the output port during weaving in the shaping and weaving mechanism, resulting in a low yield. Furthermore, each woven bread manufacturer has a different recipe, thus limiting the applicability of existing equipment.

[0004] Therefore, a bread production equipment that can position dough sheets on a conveyor belt, has a high yield rate, and is widely applicable needs to be designed. Summary of the Invention

[0005] The purpose of this invention is to address the deficiencies and shortcomings of the prior art by providing a bread production equipment that solves at least one of the aforementioned technical problems.

[0007] A frame, a conveying mechanism configured on the frame for conveying sheet material, and a processing mechanism configured on the movement path of the conveying mechanism for processing the sheet material;

[0008] The conveying mechanism includes a conveyor belt with a first vent hole;

[0009] The conveyor belt is provided with a negative pressure adsorption mechanism on its lower side, which is used to provide negative pressure to adsorb the sheet corresponding to the first ventilation hole area onto the conveyor belt.

[0013] The cutting mechanism is used to cut an inclined kerf from the creases outward to form a diagonal stripe sheet;

[0014] The shaping and weaving mechanism is used to fold the diagonal strips on the outside of the two creases in a staggered manner and weave them onto the strips inside the two creases;

[0015] The first vent is located in the area within the two folds of the corresponding surface of the conveyor belt.

[0016] Optionally, the negative pressure chamber is disposed on the lower side of the shaping and weaving mechanism and / or the cutting mechanism.

[0017] Optionally, the shaping and weaving mechanism includes: a first support plate and a second support plate symmetrically arranged on the frame relative to the conveyor belt; a first flipping sheet device assembled with the first support plate and located on the upper side of the conveyor belt, having a guide surface; a second flipping sheet device assembled with the second support plate and located on the upper side of the conveyor belt, having a guide surface, wherein the distance between the guide surfaces of the first flipping sheet device and the second flipping sheet device gradually decreases; and a first supporting rod and a second supporting rod assembled between the first support plate and the second support plate by a crossbar, and vertically offset and inclinedly disposed above the sheet area within the corresponding two folds.

[0018] Optionally, the first flipping sheet device is adjustablely mounted on the first support plate along the direction of movement of the conveyor belt; the second flipping sheet device is adjustablely mounted on the second support plate along the direction of movement of the conveyor belt, and the distance between the first flipping sheet device and the second flipping sheet device is adjustable.

[0019] Optionally, both the first and second dough support rods are rotatably and telescopically mounted on the crossbar via a double-hole cross clamp of varying diameter.

[0020] Optionally, the shaping and weaving mechanism further includes a first baffle adjusting member and a second baffle adjusting member.

[0022] Compared with the prior art, the advantages of the technical solution of this application are as follows:

[0023] Because the conveying mechanism of this bread production equipment includes a conveyor belt with a first vent, and a negative pressure adsorption mechanism is provided on the underside of the conveyor belt to provide negative pressure and adsorb the dough sheets corresponding to the first vent area onto the conveyor belt, the dough sheets will not get stuck, adhere to, or become trapped on the processing mechanism when they pass through it.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Furthermore, the terms "first," "second," etc., are only used to distinguish multiple components or structures with the same or similar structures and do not indicate any special limitation on the arrangement order or connection relationship.

[0048] Please refer to Figures 1 to 10This invention provides a bread production equipment 100 for mass production of bread. The bread production equipment 100 includes a frame 1, a conveying mechanism 2, and a processing mechanism. Optionally, the processing mechanism may include a cutting mechanism 4 and / or a shaping and weaving mechanism 5; optionally, the bread production equipment 100 may also include a width-limiting and indenting mechanism 3. The frame 1 provides an assembly station for the conveying mechanism 2, the width-limiting and indenting mechanism 3, and the processing mechanism. The conveying mechanism 2 is mounted on the frame 1 and is used to convey dough sheets 9. The width-limiting and indenting mechanism 3, the cutting mechanism 4, and the shaping and weaving mechanism 5 are sequentially arranged on the conveying path of the conveying mechanism 2 from the inlet end to the outlet end. The width-limiting crease mechanism 3 is used to cut the sheet 9 into a limited width and press out two parallel creases 91 along the forward direction of the sheet 9; the face-cutting mechanism 4 is used to cut an inclined cutting edge from the creases 91 outward to form a diagonal strip sheet 92; the shaping and weaving mechanism 5 is used to fold and weave the diagonal strip sheet 92 outside the two creases 91 in an orderly manner onto the sheet 9 within the two creases 91; the conveying mechanism 2 includes a conveyor belt 21, which is provided with a first ventilation hole c; specifically, the conveyor belt 21 is provided with a first ventilation hole c in the area corresponding to the two creases 91 of the sheet 9; a negative pressure adsorption mechanism is provided on the lower side of the conveyor belt 21 to provide negative pressure to adsorb the sheet 9 corresponding to the area of ​​the first ventilation hole c onto the conveyor belt 21; specifically, the negative pressure adsorption mechanism is used to provide negative pressure to adsorb the sheet 9 located within the two creases 91 onto the conveyor belt 21.

[0049] Because the conveying mechanism 2 of the bread production equipment 100 includes a conveyor belt 21 with a first ventilation hole c, and a negative pressure adsorption mechanism is provided on the underside of the conveyor belt 21 to provide negative pressure and adsorb the dough sheet 9 corresponding to the area of ​​the first ventilation hole c onto the conveyor belt 21, the dough sheet 9 will not get stuck, adhere to, or become stuck on the processing mechanism when it passes through the processing mechanism, since the bottom of the dough sheet corresponding to the area of ​​the first ventilation hole c is adsorbed onto the conveyor belt 21. This improves the bread production yield and allows for the application of different food manufacturers' recipes, thus having a wide range of applications.

[0050] Specifically, the first vent c is positioned within the area of ​​the two folds 91 of the dough sheet 9; and a negative pressure adsorption mechanism is provided on the underside of the conveyor belt 21 to provide negative pressure and adsorb the dough sheet 9 located within the two folds 91 onto the conveyor belt 21. Thus, when the dough sheet 9 passes through the cutting mechanism 4, because the bottom of the dough sheet 9 within the two folds 91 is adsorbed onto the conveyor belt 21, it will not get stuck on the cutting roller 48 of the cutting mechanism 4; and it will not clog the output port when the shaping and weaving mechanism 5 weaves the dough sheet 9. This improves the yield of bread production and is applicable to different food manufacturers' recipes, making it widely applicable.

[0051] Specifically, please refer to Figure 1In this embodiment, the conveying mechanism 2 further includes a drive roller 22, a driven shaft 23, and a drive motor 24 mounted on the frame 1. The output end of the drive motor 24 is connected to the drive roller 22, the driven shaft 23 is rotatably mounted on the frame 1, and the conveyor belt 21 is fitted onto the drive roller 22 and the driven shaft 23. Thus, the movement of the drive motor 24 can drive the movement of the conveyor belt 21. To adjust the tension of the conveyor belt 21 for better adaptation to bread processing, preferably, please refer to... Figure 2 In this embodiment, the driven shaft 23 is rotatably mounted on the frame 1 via a tensioning device. Specifically, the tensioning device includes an adjusting screw seat 25, which is mounted on the frame 1 by fasteners and symmetrically arranged relative to the conveyor belt 21; an adjusting screw 26 threadedly connected to the adjusting screw seat 25; and a tension adjusting plate 27 connected to the adjusting screw 26. The tension adjusting plate 27 has a first oblong hole d, and the frame 1 has a corresponding threaded hole (not shown in the figure). The tension adjusting plate 27 can be locked in place by the fasteners, the first oblong hole d, and the threaded hole. The driven shaft 23 and the two tension adjusting plates 27 are rotatably connected. Thus, the tension of the conveyor belt can be adjusted by the extension and retraction of the tension adjusting plate 27 relative to the adjusting screw seat 25 via the extension and retraction of the adjusting screw 26.

[0052] To stably provide negative pressure to adhere the sheet 9 located within the two creases 91 to the conveyor belt 21, optionally, please refer to Figure 3 , Figure 4 and Figure 5In this embodiment, the negative pressure adsorption mechanism includes a negative pressure chamber 6 and a negative pressure generating device 7. The negative pressure chamber 6 is located on the lower side of the conveyor belt 21, and a second vent p is provided corresponding to the area of ​​the conveyor belt 21 with the first vent c. The negative pressure generating device 7 is connected to the negative pressure chamber 6 through a negative pressure conveying pipe 8. Specifically, the negative pressure chamber 6 is fixed to the frame 1 by a vacuum chamber support rod 61 and is located on the lower side of the conveyor belt 21. Thus, the negative pressure generating device 7 can stably provide negative pressure through the cooperation of the negative pressure conveying pipe 8, the negative pressure chamber 6, the first vent c, and the second vent p to adsorb the sheet 9 located within the two creases 91 onto the conveyor belt 21. Preferably, the negative pressure conveying pipe 8 is a negative pressure conveying pipe with a filter. In this way, some dust and impurities will be filtered out and will not enter the negative pressure generating device 7. Optionally, the negative pressure chamber 6 is positioned from the front end of the cutting mechanism 4 to the outlet end of the shaping and weaving mechanism 5; this provides a stable negative pressure for both the cutting mechanism 4 (cutting the sheet 9) and the shaping and weaving mechanism 5 (weaving the sheet 9). Alternatively, in this technical solution, there can be multiple negative pressure chambers 6, each positioned at a different location below the conveyor belt 21. For example, there can be two negative pressure chambers 6, one positioned below the shaping and weaving mechanism 5 and the other below the cutting mechanism 4. Preferably, the negative pressure generating device 7 can provide different levels of adsorption force to different negative pressure chambers 6 to adapt to different sheet 9 processing steps; specifically, multiple negative pressure generating devices 7 can be provided, without specific limitations. Alternatively, there can be only one negative pressure chamber, positioned below the shaping and weaving mechanism 5 or the cutting mechanism 4, or the negative pressure chamber 6 can extend directly from the feed end to the discharge end of the conveyor belt; without specific limitations.

[0053] To accommodate different recipes and dough sheets 9 with varying firmness, and to provide different levels of negative pressure adsorption, the negative pressure generating device 7 has an adjustable suction force. That is, the negative pressure generating device 7 can be set with different suction levels for easy adjustment by bread manufacturers. Since the negative pressure generating device 7 is existing technology, it will not be discussed further here.

[0054] To ensure that the diagonal stripes 92 on the outer sides of the two creases 91 are folded and woven onto the stripes 9 inside the two creases 91 in a staggered manner, optionally, please refer to... Figure 1 , Figure 6 and Figure 7In this embodiment, the shaping and weaving mechanism 5 includes a first support plate 51, a second support plate 52, a first flipping sheet device 53, a second flipping sheet device 54, a first supporting rod 55, and a second supporting rod 56. The first support plate 51 and the second support plate 52 are symmetrically arranged on the frame 1 relative to the conveyor belt 21. The first flipping sheet device 53 has a guide surface m and is assembled with the first support plate 51 and located on the upper side of the conveyor belt 21. The second flipping sheet device 54 also has a guide surface m and is assembled with the second support plate 52 and located on the upper side of the conveyor belt 21. The distance between the guide surface m of the first flipping sheet device 53 and the guide surface m of the second flipping sheet device 54 gradually decreases; that is, the cross-sectional area of ​​the channel defined between the guide surface m of the first flipping sheet device 53 and the guide surface m of the second flipping sheet device 54 gradually decreases. Thus, the cut sheet 9 can change with the conveyor belt 21, gradually changing from flat to vertical or even inverted shapes. The first dough-supporting rod 55 and the second dough-supporting rod 56 are assembled between the first support plate 51 and the second support plate 52 via a crossbar 571, and are staggered vertically and inclinedly positioned above the dough sheet 9 areas within the corresponding two creases 91, with their front ends extending into the inner side of the guide surface m of the first dough sheet device 53 and the guide surface m of the second dough sheet device 54. Thus, the diagonal strip dough sheets 92 on the outer side of the two creases 91 are guided by the first dough sheet device 53 and the second dough sheet device 54, and, supported by the first dough-supporting rod 55 and the second dough-supporting rod 56, are folded and woven onto the dough sheets 9 within the two creases 91 in a staggered manner. Specifically, the shape of the guide surface m on the first dough sheet device 53 and the guide surface m on the second dough sheet device 54 can be the same or different, and no specific limitation is made here. Optionally, the guide surface m is an arc-shaped guide surface m.

[0055] Alternatively, please refer to Figure 6 and Figure 7In this embodiment, the first flipping sheet device 53 is adjustablely mounted on the first support plate 51 along the movement direction of the conveyor belt 21; the second flipping sheet device 54 is adjustablely mounted on the second support plate 52 along the movement direction of the conveyor belt 21, and the distance between the first flipping sheet device 53 and the second flipping sheet device 54 is adjustable. Specifically, the first support plate 51 is provided with a second oblong hole j, and the first flipping sheet device 53 is provided with a corresponding threaded hole (not shown in the figure); the threaded end of a long lead screw 531 is threadedly connected to the threaded hole of the first flipping sheet device 53 and locked by a nut, and the smooth end of the long lead screw 531 is engaged with the second oblong hole j and locked on the first support plate 51 by a nut. Similarly, the assembly method of the second flipping sheet device 54 and the second support plate 52 is the same as the assembly method of the first flipping sheet device 53 and the first support plate 51 described above, and will not be repeated here. Since the first flipping sheet device 53 can achieve telescopic movement in cooperation with the long lead screw 531, and the second flipping sheet device 54 can also achieve telescopic movement in cooperation with the long lead screw 531, the distance between the first flipping sheet device 53 and the second flipping sheet device 54 can be adjusted to accommodate different sheet widths 9. Furthermore, the adjustable first flipping sheet device 53 and the second flipping sheet device 54 along the direction of movement of the conveyor belt 21 allows them to be staggered, and while their guide surfaces m have similar shapes, the diagonal strip sheets 92 outside the creases can be folded and woven into the sheets 9 within the two creases 91 in a staggered manner.

[0056] To facilitate adjustment of the tilt angle of the first and second dough-supporting rods 55 relative to the dough piece 9, their extension lengths, and the distance between the two rods, optionally, please refer to... Figure 7 In this embodiment, both the first dough support rod 55 and the second dough support rod 56 are rotatably and telescopically mounted on the crossbar 571 via a variable-diameter double-hole cross clamp 572. Specifically, the variable-diameter double-hole cross clamp 572 has two mutually perpendicular shaft holes. One shaft hole is used to rotatably mount the variable-diameter double-hole cross clamp 572 on the crossbar 571 and lock it with a fastener; the other shaft hole is used to tighten the first dough support rod 55, and when adjusted to the appropriate extension length, it is locked with a fastener. The assembly of the second dough support rod 56 and the crossbar 571 is similar and will not be described in detail here.

[0057] To allow for more flexible configuration of the guide structure and angle of the first flipping sheet device 53 and the second flipping sheet device 54 in the shaping and knitting mechanism 5, optionally, please refer to... Figure 6 and Figure 7In this embodiment, the shaping and weaving mechanism 5 further includes a first baffle adjustment member 28 and a second baffle adjustment member 29. The first baffle adjustment member 28 is located at the front end of the first support rod 55, vertically positioned above the conveyor belt 21, and is adjustable in angle relative to the vertical plane and mounted on the first flipping sheet device 53. Thus, the first baffle adjustment member 28 can cooperate with the guide surface m of the first flipping sheet device 53 and the first support rod 55 to better achieve the effect of folding the oblique strip sheet 92. Furthermore, since the angle of the first baffle adjustment member 28 relative to the vertical plane is adjustable, it can adapt to oblique strip sheets 92 with different tilt angles, thus broadening its applicability. Specifically, the first baffle adjustment member 28 includes a first connecting plate 281, a first rotating cylinder 282, a first U-shaped baffle 283, and a first fastener 284. The first connecting plate 281 is mounted on the first flipping plate device 53. The first connecting plate 281 has a first stepped through hole (not shown in the figure) in the vertical direction. The first rotating cylinder 282 is rotatably disposed on the stepped surface within the first stepped through hole. The first U-shaped stop bar 283 and the first rotating cylinder 282 are assembled and connected. The first fastener 284 is used to lock the first connecting plate 281 and the first rotating cylinder 282. Specifically, the two free ends of the first U-shaped stop bar 283 are bent and fixed to the first rotating cylinder 282 by screws. Optionally, the first fastener 284 is a screw. After adjusting the angle between the first U-shaped stop bar 283 and the vertical plane, the first connecting plate 281 and the first rotating cylinder 282 can be locked by the screw.

[0058] The structure and assembly method of the second baffle adjustment component 29 are similar to those of the first baffle adjustment component 28. Specifically, the second baffle adjustment component 29 is located at the front end of the second support rod 56, vertically positioned above the conveyor belt 21, and is assembled on the second flipping sheet device 54 with an adjustable angle relative to the vertical plane. Thus, the second baffle adjustment component 29 can cooperate with the guide surface m of the second flipping sheet device 54 and the second support rod 56 to better achieve the effect of folding the inclined strip sheet 92. Furthermore, since the angle of the second baffle adjustment component 29 relative to the vertical plane is adjustable, it can adapt to inclined strip sheets 92 with different tilt angles, thus broadening its applicability. Specifically, the second baffle adjustment component 29 includes a second connecting plate 291, a second rotating cylinder 292, a second U-shaped baffle 293, and a second fastener 294. The second connecting plate 291 is mounted on the second flip-up device 54. The second connecting plate 291 has a second stepped through hole o in the vertical direction. The second rotating cylinder 292 is rotatably disposed on the stepped surface within the second stepped through hole o. The second U-shaped stop bar 293 and the second rotating cylinder 292 are assembled and connected. The second fastener 294 is used to lock the second connecting plate 291 and the second rotating cylinder 292. Specifically, the two free ends of the second U-shaped stop bar 293 are bent and then fixed to the second rotating cylinder 292 by screws. Optionally, the second fastener 294 is a screw. After adjusting the angle between the second U-shaped stop bar 293 and the vertical plane, the second connecting plate 291 and the second rotating cylinder 292 can be locked by the screw.

[0059] To adapt the cutting mechanism 4 to sheet pieces 9 of different thicknesses, optionally, please refer to... Figure 8 and Figure 9 In this embodiment, the slicing mechanism 4 includes: a first slicing support 41, a second slicing support 42, a slicing shaft 43, and two slicing rollers 48. The first slicing support 41 and the second slicing support 42 are symmetrically arranged on the frame 1 relative to the conveyor belt 21. Specifically, the first slicing support 41 includes a first fixing plate 411 fixed to the outer wall of the frame 1, two first lifting guide rods 412 vertically mounted on the first fixing plate 411, and a first frame plate 413 mounted to the upper ends of the two first lifting guide rods 412. Similarly, the second slicing support 42 includes a second fixing plate 421 fixed to the other outer wall of the frame 1 relative to the conveyor belt 21, two second lifting guide rods 422 vertically mounted on the second fixing plate 421, and a second frame plate 423 mounted to the upper ends of the two second lifting guide rods 422.

[0060] The height of the cutting axis 43 is adjustable and positioned between the first cutting support 41 and the second cutting support 42. Specifically, the cutting mechanism 4 further includes a height adjustment assembly, which includes a first height adjustment assembly that cooperates with the first support plate 413, a second height adjustment assembly that cooperates with the second support plate 423, and a synchronization adjustment assembly that synchronizes the movement of the first and second height adjustment assemblies. Specifically, the first height adjustment assembly includes a first lead screw 441 that is threadedly engaged with the first support plate 413, a first lead screw nut 442 that cooperates with the first lead screw 441, a first slide block 443 that is assembled and connected to the first lead screw nut 442 and can slide up and down relative to the first lifting guide rod 412, and a first locking block 444 for locking the first slide block 443 and the first lifting guide rod 412. Specifically, the first lead screw 441 can be located between the two first lifting guide rods 412; the first slide block 443 is provided with a sliding hole e that mates with the two first lifting guide rods 412, a clearance hole f that avoids the first lead screw 441, a locking groove g for assembling the first locking block 444, a nut assembly hole h for assembling the first lead screw nut 442, and a scissor hole i for mates with the scissor shaft 43.

[0061] Two cutting rollers 48 are rotatably mounted on the cutting shaft 43, corresponding to the outer region of the fold 91 of the sheet 9. Thus, as the conveyor belt 21 moves the sheet 9 forward, the two cutting rollers 48 can cut the sheet 9 from the fold 91 outwards, creating a backward-sloping cutting edge to form a diagonal sheet 92. Preferably, the cutting rollers 48 can be fixed to the cutting shaft 43 with screws, allowing adjustment of the distance between the two cutting rollers 48 to accommodate sheets 9 of different thicknesses. Optionally, to improve the cutting effect of the cutting mechanism 4, a first drive roller 11 is provided on the underside of the conveyor belt 21 corresponding to the cutting rollers 48.

[0062] To cut the sheet 9 to a defined width and press two parallel creases 91 along the advancing direction of the sheet 9 for subsequent processing, please refer to... Figure 10 Optionally, in this embodiment, the width-limiting indentation mechanism 3 includes: a first width-limiting indentation frame 31, a second width-limiting indentation frame 32, a blade positioning shaft 33, two indentation blades 34, and two longitudinal cutting blades 35. Specifically, the first width-limiting indentation frame 31 and the second width-limiting indentation frame 32 are symmetrically arranged on the frame 1 relative to the conveyor belt 21, and the height of the first width-limiting indentation frame 31 and the second width-limiting indentation frame 32 relative to the frame 1 is adjustable; the blade positioning shaft 33 is rotatably mounted on the first width-limiting indentation frame 31 and the second width-limiting indentation frame 32; the two indentation blades 34 for pressing two parallel creases 91 on the sheet 9 are mounted on the blade positioning shaft 33; the two longitudinal cutting blades 35 for cutting the sheet 9 into a limited width are mounted on the blade positioning shaft 33 and located outside the indentation blades 34. Thus, when the conveyor belt 21 carries the pre-treated sheet 9 through the width limiting and indentation mechanism 3, the two longitudinal cutting blades 35 can cut off the excess sheet 9 on both sides to limit the width of the processed sheet 9; while the two indentation blades 34 can press out two parallel creases 91 on the sheet 9 along the forward direction of the sheet 9.

[0063] To achieve synchronized height adjustment of the first width-limiting indentation frame 31 and the second width-limiting indentation frame 32 relative to the frame 1, please refer to... Figure 10Optionally, in this embodiment, one end of the first width-limiting indentation frame 31 is hinged to the outer wall of the frame 1, and its middle position is connected to the first tool holder turntable 362 through a tension spring 361. The other end of the first width-limiting indentation frame 31 and the blade positioning shaft 33 are rotatably assembled through a bearing. The first tool holder turntable 362 is rotatably mounted on the outer wall of the frame 1. The outer wall of the frame 1 and the rotation shaft of the first tool holder turntable 362 are coaxially provided with a plurality of first positioning holes b. The first tool holder turntable 362 is locked by inserting a first positioning pin 363 into one of the first positioning holes b on the outer wall of the frame 1. A second handle 39 is provided on the outer side of the first tool holder turntable. Similarly, one end of the second width-limiting indentation frame 32 is hinged to the other outer wall of the frame 1 relative to the conveyor belt 21, and its middle position is connected to the second tool holder turntable 37 via a tension spring 361. The other end of the second width-limiting indentation frame 32 and the blade positioning shaft 33 are rotatably assembled via bearings. The second tool holder turntable 37 is connected to the second tool holder turntable 37 via a roller cutter shaft 38 and is synchronously rotatable on the outer wall of the frame 1. Thus, by rotating the second handle 39 on the first tool holder turntable 362, the height of the first width-limiting indentation frame 31 and the second width-limiting indentation frame 32 relative to the frame 1 can be adjusted to achieve height adjustment of the blade positioning shaft 33, thereby adjusting the height of the two indentation blades 34 and the two longitudinal cutting blades 35 relative to the sheet 9 to accommodate sheet 9 of different thicknesses. Optionally, in order to improve the cutting and indentation effect of the width-limiting indentation mechanism 3, a second drive roller 12 is provided on the lower side of the conveyor belt 21 corresponding to the indentation blades 34 and the two longitudinal cutting blades 35.

[0064] The working principle or process of this invention is roughly as follows:

[0065] First, the pre-treated sheet 9 with two parallel creases 91 is placed at the inlet end of the conveyor belt 21 of the conveying mechanism 2. Thus, the sheet 9 can be moved forward by the movement of the conveyor belt 21. The outer sheet 9 with creases 91 is formed into a diagonal strip sheet 92 inclined outward from the creases 91 by the action of the two cutting rollers 48 of the cutting mechanism 4. Then, the shaping and weaving mechanism 5, through the cooperation of the first flipping sheet device 53, the second flipping sheet device 54, the first supporting sheet rod 55 and the second supporting sheet rod 56 and the conveyor belt 21, folds and weaves the diagonal strip sheet 92 outside the two creases 91 in an orderly manner onto the sheet 9 within the two creases 91. Since the conveyor belt 21 is provided with a first ventilation hole c in the area corresponding to the two creases 91 of the sheet 9, and a negative pressure adsorption mechanism is provided on the lower side of the conveyor belt 21 to provide negative pressure to adsorb the sheet 9 located within the two creases 91 onto the conveyor belt 21. In this way, when the dough sheet 9 passes through the cutting mechanism 4, the bottom of the dough sheet 9 within the two folds 91 is attracted to the conveyor belt 21, so it will not get stuck on the cutting roller 48 of the cutting mechanism 4; when the shaping and weaving mechanism 5 weaves the dough sheet 9, it will not block the output port. This improves the yield of bread production and can be used with different food manufacturers' recipes, making it widely applicable.
