[0038] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations. Example

[0039] Please refer to Figures 1 to 12 The present embodiment provides a hollow noodle production line 5, which includes a strip production line 1 and a plurality of strip rolling devices 510 and a plurality of wire rod devices 530. The plurality of strip rolling devices 510 correspond to the plurality of wire rod devices 530 one by one, and are connected by a fifth conveyor belt 550 to form a plurality of parallel wire rod production lines. The plurality of strip noodle embryos made by the strip production line 1 can enter different wire rod production lines respectively, realizing one-to-many production, thereby realizing assembly line production while reducing costs and improving production efficiency.

[0040] In this embodiment, the strip production line 1 includes a flattening device 2, a proofing device 3 and a stripping device 4 which are arranged in sequence. The flattening device 2 includes a first conveyor belt 210, a first rolling assembly 230 and a cutting assembly 270. The first rolling assembly 230 and the cutting assembly 270 are both installed on the first conveyor belt 210. The first rolling assembly 230 can flatten the dough on the first conveyor belt 210. The cutting assembly 270 is used to cut the flattened dough along the width direction of the first conveyor belt 210. The proofing device 3 includes a second conveyor belt 310, a third conveyor belt 330, a folding assembly 350 and a second rolling assembly 370. The second conveyor belt 310 is arranged at one end of the first conveyor belt 210 where the cutting assembly 270 is arranged. The third conveyor belt 330 is arranged at one end of the second conveyor belt 310, and the end close to the second conveyor belt 310 is lower than the second conveyor belt 310. The folding assembly 350 is arranged between the second conveyor belt 310 and the third conveyor belt 330, and the second rolling assembly 370 is arranged on the third conveyor belt 330. The dough embryos cut by the cutting assembly 270 can be spliced ​​along the length direction of the dough embryos on the second conveyor belt 310 to form continuous strip-shaped dough embryos, and can be transported by the second conveyor belt 310 and folded in the width direction by the folding assembly 350 to the third conveyor belt 330, and the second rolling assembly 370 can roll the folded dough embryos. The stripping device 4 includes a frame 410, a roller assembly 420, a cutter assembly 430 and a second driving assembly 440. The roller assembly 420 and the cutter assembly 430 are both installed on the frame 410. The cutter assembly 430 has a plurality of blades 431 arranged at intervals. The second driving assembly 440 is installed on the frame 410, and is transmission-connected to both the roller assembly 420 and the cutter assembly 430. The dough blanks conveyed by the third conveyor belt 330 may be conveyed to the cutter assembly 430 by the roller assembly 420 , and the cutter assembly 430 may cut the dough blanks into a plurality of strips along the width direction of the dough blanks.

[0041] In this embodiment, by providing a flattening device 2, a proofing device 3 and a stripping device 4, the kneaded dough can be flattened by the first rolling assembly 230, and cut into strips along the width direction by the cutting assembly 270, and then spliced ​​along the length direction on the second conveyor belt 310 of the proofing device 3 to form a continuous long strip of dough, so as to facilitate subsequent assembly line production. A folding assembly 350 is provided between the second conveyor belt 310 and the third conveyor belt 330, which can fold the dough in the width direction and pass through the second flattening device 2 for flattening treatment, so as to be more conducive to further proofing of the dough, and the stripping device 4 can separate the proofed dough into multiple strips along the width direction, so as to complete the strip making.

[0042] Please refer to Figures 2 to 5In this embodiment, the movement direction of the first conveyor belt 210 is always moving in the direction of the cutting assembly 270. The cutting assembly 270 is disposed at one end of the first conveyor belt 210, and can cut the blank carried on the first conveyor belt 210 along the width direction of the first conveyor belt 210. The first rolling assembly 230 is movably mounted on the first conveyor belt 210, so that the first rolling assembly 230 can reciprocate in the conveying direction of the first conveyor belt 210. When the first rolling assembly 230 moves in a direction away from the cutting assembly 270, the blank on the first conveyor belt 210 can be pressed into a sheet. When the first rolling assembly 230 moves in a direction close to the cutting assembly 270, the first rolling assembly 230 can be lifted.

[0043] In this embodiment, by setting the first conveyor belt 210, the blank placed on the upper part can be automatically conveyed according to the processing requirements. When preparing hollow noodles, the first conveyor belt 210 can also be used as a fermentation bed. The first roller pressing assembly 230 and the cutting assembly 270 are set on the first conveyor belt 210, so that the first roller pressing assembly 230 flattens the blank on the first conveyor belt 210 into a sheet, and the cutting assembly 270 can cut the sheeted blank into long strips according to the requirements. Secondly, when making hollow noodles, the dough embryo carried on the first conveyor belt 210 will become uneven in thickness after the first roller pressing assembly 230 rolls, but it will also become uneven in thickness after the time of proofing. Therefore, the first roller pressing assembly 230 is movably installed on the first conveyor belt 210 in this application, so that before cutting, the first roller pressing assembly 230 can reciprocate in the transmission direction of the first conveyor belt 210, so as to further flatten the flattened dough embryo, and then cut it, so that the cut long strips of dough embryo can be uniform in thickness. Furthermore, since the first rolling assembly 230 will cause the dough embryo to be squeezed to both sides during the reciprocating rolling process, the cutting surface on the side cut by the cutting assembly 270 will be convex and uneven, which will affect the shape of the long strip of dough embryo when cutting next time. In this embodiment, the first rolling assembly 230 is set to be liftable, so that when the rolling assembly moves away from the cutting assembly 270, the first rolling assembly 230 will not be lifted, so that the side of the dough embryo away from the cutting assembly 270 can extend outward during rolling. When the first rolling assembly 230 moves toward the direction close to the cutting assembly 270, the first rolling assembly 230 is lifted, and the dough embryo will not be squeezed, and the dough embryo will not be squeezed toward one side of the cutting assembly 270, so that the cutting surface can be ensured to be flush.

[0044] In this embodiment, the first transmission belt 210 mainly includes a fixed frame, a belt body, a driving device, a roller, a tensioning device and other components. A roller is provided at each end of the fixed frame. The belt body is wound around two rollers, and the driving device is connected to one of the rollers. The operation of the driving device can drive the roller to rotate, thereby driving the belt body to move.

[0045] In this embodiment, the first rolling assembly 230 includes a moving assembly 231 and a pressure roller 232. The moving assembly 231 is installed on the first conveyor belt 210. Specifically, the moving assembly 231 is installed on the fixed frame of the first conveyor belt 210. The pressure roller 232 is movably installed on the moving assembly 231. The moving assembly 231 can drive the pressure roller 232 to reciprocate along the conveying direction of the first conveyor belt 210. When the moving assembly 231 drives the pressure roller 232 to move in a direction away from the cutting assembly 270, the pressure roller 232 can press the blank carried on the first conveyor belt 210 into a sheet. When the moving assembly 231 drives the pressure roller 232 to move in a direction close to the cutting assembly 270, the pressure roller 232 can be lifted.

[0046] In this embodiment, the pressure roller 232 is lifted, so that the structure can be simpler.

[0047] Of course, in some other embodiments of the present application, the first rolling assembly 230 can also be raised and lowered relative to the first conveyor belt 210. For example, the first rolling assembly 230 can be connected to the first conveyor belt 210 via an electric, pneumatic or hydraulic cylinder or other retractable components, so that the first rolling assembly 230 can be lifted as a whole. Therefore, when moving toward the cutting assembly 270, the first rolling assembly 230 is lifted as a whole and will not squeeze the dough blank. When the first rolling assembly 230 moves in a direction away from the cutting assembly 270, the first rolling assembly 230 can be lowered as a whole to a preset height to roll the dough blank.

[0048] Please refer to Figures 2 to 5 In this embodiment, the moving assembly 231 includes a mounting frame 233 and a moving assembly 234. The pressure roller 232 is movably mounted on the mounting frame 233. The moving assembly 234 is disposed on the first conveyor belt 210, and the mounting frame 233 is transmission-connected to the first conveyor belt 210. The moving assembly 234 can drive the mounting frame 233 to reciprocate along the transmission direction of the first conveyor belt 210. When the mounting frame 233 moves toward the direction close to the cutting assembly 270, the pressure roller 232 can be lifted relative to the mounting frame 233 under the action of the blank. When the mounting frame 233 moves toward the direction away from the cutting assembly 270, the mounting frame 233 can limit the movement of the pressure roller 232 so that the pressure roller 232 can press the blank into a sheet.

[0049] In this embodiment, the pressure roller 232 is movably mounted on the mounting frame 233, and the motion component 234 is arranged on the first conveyor belt 210. The motion component 234 does not make a lifting motion relative to the first conveyor belt 210, and only the pressure roller 232 makes a lifting motion relative to the mounting frame 233, and the structure is simple. When the mounting frame 233 moves away from the cutting assembly 270, the lifting of the pressure roller 232 is limited by the position limit of the mounting frame 233 on the pressure roller 232, and when moving in the reverse direction, the force direction of the pressure roller 232 changes, and the pressure roller 232 can be lifted relative to the mounting frame 233.

[0050] In this embodiment, the pressure roller 232 is provided with a connecting portion 235. The connecting portion 235 is hinged to the mounting frame 233 through a rotating shaft 236. The axis of the rotating shaft 236 is parallel to and spaced from the axis of the pressure roller 232. A limiting portion 237 is provided on the mounting frame 233 at a side of the pressure roller 232 close to the cutting assembly 270. When the mounting frame 233 moves in a direction close to the cutting assembly 270, the pressure roller 232 is lifted by rotating along the rotating shaft 236 in a direction away from the cutting assembly 270 under the action of the blank. When the mounting frame 233 moves in a direction away from the cutting assembly 270, the pressure roller 232 abuts against the limiting portion 237, which can limit the pressure roller 232 from rotating along the rotating shaft 236 in a direction close to the cutting assembly 270.

[0051] In this embodiment, a connecting portion 235 is provided on the pressing roller 232, and the axis of the rotating shaft 236 that is connected to the pressing roller 232 and the mounting frame 233 is spaced apart from and parallel to the axis of the pressing roller 232, so that the pressing roller 232 can swing along the axis of the rotating shaft 236 according to the force. A limiting portion 237 is provided on the side of the mounting frame 233 away from the cutting assembly 270, so that when the mounting frame 233 moves in a direction away from the cutting assembly 270, the dough embryo will give the pressing roller 232 a force component to push the pressing roller 232 in the direction of the cutting assembly 270, but the limiting portion 237 is provided, so that the pressing roller 232 is limited from moving along the rotating shaft 236 in the direction close to the cutting assembly 270. When the mounting frame 233 moves in a direction close to the cutting assembly 270, the pressing roller 232 is subjected to a force from the dough embryo in the direction away from the cutting assembly 270, and the limiting portion 237 is not provided in this direction, so that the pressing roller 232 rotates along the rotating shaft 236, thereby lifting. This arrangement has a simple structure and can be realized without the need to provide electric drive components and electric control components.

[0052] Please refer to Figures 2 to 5In this embodiment, the pressure roller 232 includes a mounting shaft 238 and a rotating roller 239. The rotating roller 239 is rotatably mounted on the mounting shaft 238, and both ends of the mounting shaft 238 extend out of both ends of the rotating roller 239. Connecting portions 235 are respectively provided at both ends of the mounting shaft 238 along the radial direction of the mounting shaft 238. Two connecting lugs 241 corresponding to the two connecting portions 235 are provided on the side of the mounting frame 233 away from the cutting assembly 270. The two connecting lugs 241 are hinged to the two connecting portions 235 through the rotating shaft 236 in a one-to-one correspondence. A limiting portion 237 is formed on the end surface of one side of the mounting frame 233 away from the cutting assembly 270.

[0053] Of course, in some other embodiments of the present application, the mounting shaft 238 may be connected to the mounting frame 233 by telescopic elements such as telescopic cylinders, hinges, etc., so as to achieve the lifting of the pressure roller 232.

[0054] Secondly, an arcuate slot or an inclined slot may be provided on the mounting frame 233. The mounting shaft 238 is installed in the arcuate slot or the inclined slot, and can slide and rise along the arcuate slot or the inclined slot when the pressure roller 232 is subjected to a force moving away from the cutting assembly 270.

[0055] In this embodiment, the motion assembly 234 includes a fixing member 242, a first rack 243, a driving motor 244 and a slide rail assembly 245. The number of the first racks 243 includes two. The two first racks 243 are respectively installed on both sides of the length direction of the first conveyor belt 210 through the fixing member 242, and the side of the first rack 243 with teeth faces the first conveyor belt 210. The mounting frame 233 includes a transverse plate 248 and end plates 249 arranged on both sides of the transverse plate 248. The transverse plate 248 is installed above the two first racks 243 through the slide rail assembly 245, and can reciprocate along the length direction of the first racks 243. The two connecting ears 241 are respectively connected to the two end plates 249. The two ends of the pressure roller 232 are movably connected to the end plates 249 on both sides through the two connecting ears 241. A transmission shaft is rotatably disposed between the two end plates 249, and positions on the transmission shaft corresponding to the two first racks 243 are respectively provided with first gears 251 meshing with the first racks 243. The drive motor 244 is mounted on the outer side of one end plate 249, and the output shaft of the drive motor 244 is connected to the transmission shaft.

[0056] In this embodiment, a first rack 243 and a driving motor 244 are provided, and a first gear 251 is provided on the driving motor 244. The driving motor 244 drives the first gear 251 to rotate, thereby driving the mounting frame 233 to reciprocate along the first rack 243. The structure is simple.

[0057] Please refer to Figures 2 to 5In this embodiment, the fixing member 242 includes a plurality of first screw rods 247. The plurality of first screw rods 247 are vertically mounted on both sides of the first conveyor belt 210, and the first rack 243 is mounted on the top of the first screw rods 247. The mounting height of the first rack 243 can be adjusted by the first screw rods 247 to adjust the height of the pressure roller 232.

[0058] In this embodiment, the fixing member 242 is set as the first screw rod 247, so that the installation height of the first rack 243 can be adjusted by the first screw rod 247, and then the height of the pressing roller 232 can be adjusted, so as to change the thickness of the dough blank when flattened.

[0059] Specifically, a through hole is provided on the first rack 243, and the first screw 247 is inserted into the through hole. Two nuts are provided on the first screw 247, one nut is located at the top of the first rack 243, and the other nut is located at the bottom of the first rack 243. The first rack 243 is fixed by clamping the two nuts, and the height of the first rack 243 can be adjusted by adjusting the two nuts.

[0060] Of course, in some other embodiments of the present application, the fixing member 242 can also be directly configured as an electric telescopic element. In this way, the thickness of the pressed dough embryo can be adjusted, and the pressing roller 232 can be lifted at the same time.

[0061] In this embodiment, the cutting assembly 270 includes a supporting bracket 271, a cutting blade 272, and a first driving assembly 273. The supporting bracket 271 is disposed on the first conveyor belt 210 along the width direction of the first conveyor belt 210. The first driving assembly 273 is mounted on the supporting bracket 271, and the cutting blade 272 is transmission-connected to the first driving assembly 273. The first driving assembly 273 can drive the cutting blade 272 to move along the supporting bracket 271.

[0062] In this embodiment, the first driving assembly 273 is installed on the supporting bracket 271 , so that the first driving assembly 273 can drive the cutting blade 272 to move along the supporting bracket 271 , thereby achieving better cutting.

[0063] Please refer to Figures 2 to 5In this embodiment, the support bracket 271 includes two support members 274, four second screw rods 275, two second racks 276, a mounting plate 277, a gear shaft 278 and two proximity switches 281 arranged on both sides of the first conveyor belt 210 in the width direction.

The mounting plate 277 is then movably installed on the two second racks 276 by means of a slide rail and a slider, and the second gear 283 provided with the motor 279 is meshed with the second rack 276, so that the operation of the motor 279 can drive the mounting plate 277 to move, and the cutting blade 272 is connected to the mounting plate 277 through the mounting sheet, so that the cutting blade 272 can be easily driven to move. Two proximity switches 281 are provided at both ends of the second rack 276 for easy automatic control. The automatic control can be realized by a controller such as a PLC.

[0065] Please refer to Figures 6 to 9 In this embodiment, the folding assembly 350 includes a mounting base 351 and a plurality of guide rods 352. The mounting base 351 is generally mounted between the second conveyor belt 310 and the third conveyor belt 330 in the height direction. The plurality of guide rods 352 are mounted on the mounting base 351 and are rotatable and mutually enclosed to form a folding channel 353. The strip noodle embryos are guided by the plurality of guide rods 352 of the folding channel 353 and can be folded in the width direction of the strip noodle embryos.

[0066] In this embodiment, a plurality of guide rods 352 are arranged on the mounting base 351, and the guide rods 352 are used to form a folding channel 353, so that when the continuous noodle strips transported by the second conveyor belt 310 pass through the folding channel 353, the plurality of guide rods 352 guide and cooperate with each other to fold the noodle strips in the width direction. No driving device is required, and the noodle strips can be folded when passing through.

[0067] In this embodiment, the second conveyor belt 310 and the third conveyor belt 330 are placed vertically. The plurality of guide rods 352 include a first guide rod 354, a second guide rod 355 and a third guide rod 356. The first guide rod 354 and the second guide rod 355 are arranged at an angle and are both fixedly connected to the mounting base 351. The opening area formed by the first guide rod 354 and the second guide rod 355 faces the second conveyor belt 310. The third guide rod 356 is fixedly connected to the mounting base 351 and encloses the first guide rod 354 and the second guide rod 355 to form a folded channel 353. The projections of the first guide rod 354, the second guide rod 355 and the third guide rod 356 on the third conveyor belt 330 are triangular.

[0068] In this embodiment, the first guide rod 354, the second guide rod 355 and the third guide rod 356 are arranged in a triangular shape in space, so that when the strip noodle embryo moves down along the folding channel 353, the first guide rod 354 and the second guide rod 355 arranged at an angle will guide the two sides of the strip noodle embryo toward the middle for winding, and fold the noodle embryo in the width direction at the intersection of the first guide rod 354 and the second guide rod 355. The third guide rod 356 is used to limit the noodle embryo so that the noodle embryo can contact the first guide rod 354 and the second guide rod 355 when passing through the folding channel 353.

[0069] It should be noted that the width of the continuous strip of dough is generally greater than the side length of the triangular folding channel 353, so that the dough can better contact the first guide rod 354 and the second guide rod 355 when passing through, so that the first guide rod 354 and the second guide rod 355 can be used to guide the dough so that the dough can be folded. The second conveyor belt 310 and the third conveyor belt 330 are placed vertically so that the folded dough can be placed horizontally on the third conveyor belt 330 and transported by the third conveyor belt 330.

[0070] Please refer to Figures 6 to 9In this embodiment, the plurality of guide rods 352 further include a fourth guide rod 357 and a fifth guide rod 358. The third conveyor belt 330 is configured to transport the dough embryos from the first guide rod 354 to the second guide rod 355. In the height direction, the second guide rod 355 is located below the first guide rod 354, and the third guide rod 356 is located between the first guide rod 354 and the second guide rod 355. The fourth guide rod 357 is fixedly mounted on the mounting base 351, and is inclined toward one side of the second guide rod 355, and is located below the second guide rod 355. The angle between the projections of the first guide rod 354 and the second guide rod 355 on the third conveyor belt 330 is greater than the angle between the projections of the first guide rod 354 and the fourth guide rod 357 on the third conveyor belt 330. The fifth guide rod 358 is disposed below the fourth guide rod 357, and is perpendicular to the conveying direction of the third conveyor belt 330. The included angle between the projections of the first guide rod 354 and the fourth guide rod 357 on the third conveyor belt 330 is greater than the included angle between the projections of the first guide rod 354 and the fifth guide rod 358 on the third conveyor belt 330 .

[0071] In this embodiment, the fourth guide rod 357 is arranged below the second guide rod 355 at an interval, and the angle is smaller, so that the dough embryo folded in half by the first guide rod 354 and the second guide rod 355 can be further folded in half by the fourth guide rod 357 with a smaller angle, so that the folding angle becomes smaller. The fifth guide rod 358 is arranged parallel to the width direction of the third conveyor belt 330, so that the angle is smaller. The most important thing is to change the direction of the dough embryo so that it can be placed on the third conveyor belt 330 along the conveying direction of the third conveyor belt 330, thereby completing the folding of the dough embryo along the width direction and can be placed horizontally on the third conveyor belt 330.

[0072] Please refer to Figures 6 to 9 In this embodiment, a slide groove 359 is provided on the mounting base 351 , and a plurality of guide rods 352 are correspondingly installed in the slide groove 359 .

[0073] In this embodiment, a slide groove 359 is provided on the mounting base 351, so that the mounting positions of the first guide rod 354, the second guide rod 355, the third guide rod 356, the fourth guide rod 357 and the fifth guide rod 358 can be adjusted, which is more convenient for setting, debugging and installation.

[0074] It should be noted that the mounting base 351 is welded to the metal support frames of the second conveyor belt 310 and the third conveyor belt 330 .

[0075] Further, the guide rod 352 includes a mounting rod 361 and a rotating drum 362 rotatably disposed on the mounting rod 361. The mounting rod 361 is connected to the mounting base 351, and the mounting rod 361 is a metal rod, and is provided with threads, and the angle of the rotating drum 362 can be changed by bending.

[0076] In this embodiment, the mounting rod 361 is set as a threaded metal rod, and the metal rod can be installed in the slide groove 359 through a nut. During debugging, the metal rod can be bent to achieve a desired tilt angle to achieve better installation. A rotating drum 362 is set outside the mounting rod 361, so that the rotating drum 362 can rotate when the dough embryo contacts the dough embryo and the dough embryo moves downward, so as not to affect the outer surface of the dough embryo.

[0077] Please refer to Figures 6 to 9 In this embodiment, the second rolling assembly 370 includes a mounting bracket 371, a first pressing roller 372, a second pressing roller 373, an adjustment assembly 374 and a third driving assembly (not shown). The mounting bracket 371 is arranged on both sides of the third conveyor belt 330. The first pressing roller 372 is mounted on the mounting bracket 371 and is located above the third conveyor belt 330. The second pressing roller 373 is mounted on the mounting bracket 371 through the adjustment assembly 374, and the adjustment assembly 374 is configured to adjust the distance between the first pressing roller 372 and the second pressing roller 373. The third driving assembly is arranged on the mounting bracket 371, and is transmission-connected with the first pressing roller 372 and the second pressing roller 373, and can drive the first pressing roller 372 and the second pressing roller 373 to rotate.

[0078] In this embodiment, the passage between the first pressing roller 372 and the second pressing roller 373 is provided to roll the folded dough embryo, so that the two folded parts can be formed into a whole. The rolling by the first pressing roller 372 and the second pressing roller 373 can prevent the dough embryo from being adhered to the third conveyor belt 330 after rolling. The adjustment component 374 can adjust the position of the second pressing roller 373, thereby adjusting the distance between the first pressing roller 372 and the second pressing roller 373, so as to meet the selection of different required thicknesses.

[0079] In this embodiment, the mounting bracket 371 is provided with a guide rail groove 376. The adjustment assembly 374 includes a mounting seat 377, a screw rod 378 and a hand wheel 379. The mounting seat 377 is provided in the guide rail groove 376, and the second pressure roller 373 is rotatably mounted on the mounting seat 377. The mounting bracket 371 is provided with a threaded hole 381 connected to the guide rail groove 376, one end of the screw rod 378 is rotatably connected to the mounting seat 377, and the other end passes through the threaded hole 381 and is threadedly engaged with the threaded hole 381. The hand wheel 379 is installed on the screw rod 378, and rotating the hand wheel 379 can drive the screw rod 378 to rotate so as to drive the mounting seat 377 to move along the direction of the guide rail groove 376.

[0080] In this embodiment, the hand wheel 379 and the screw rod 378 are used for transmission, so that the mounting seat 377 can be driven to move along the guide groove 376 to adjust the distance between the first pressure roller 372 and the second pressure roller 373 .

[0081] Please refer to Figures 6 to 9In this embodiment, two guide rods are arranged on the mounting base 351 in an inclined manner toward the first pressing roller 372, and the two guide rods are arranged on both sides of the width direction of the first pressing roller 372. In this way, the folded dough will go along the gap between the two guide rods and enter the gap between the first pressing roller 372 and the second pressing roller 373 under the guidance of the guide rods.

[0082] Furthermore, the width of the first pressing roller 372 is greater than that of the second pressing roller 373, and opposite limiting rings are provided at both ends of the rolling surface of the first pressing roller 372. The second pressing roller 373 is located between the two limiting rings, and the distance between the two annular limiting plates is slightly greater than the distance between the two ends of the second pressing roller 373, so that the first pressing roller 372 and the second pressing roller 373 do not affect each other when they rotate relative to each other. The provision of the two annular limiting plates can prevent the squeezed dough from overflowing from the side, thereby ensuring that the dough rolled by the first pressing roller 372 and the second pressing roller 373 has the same width.

[0083] Of course, in some other embodiments of the present application, only the second pressing roller 373 may be provided, and the first pressing roller 372 may be omitted. When the folded dough embryo is conveyed by the third conveyor belt 330 and rolled by the second pressing roller 373, it will be rolled by the pressing roller 232. This structure is simple, but there is a risk that the dough embryo rolled by the second pressing roller 373 may adhere to the third conveyor belt 330.

[0084] Furthermore, the second conveyor belt 310 is provided with a heat preservation cover, which covers the outer periphery of the conveying surface of the second conveyor belt 310 to achieve heat preservation and moisture retention, so that the dough embryos can be proofed again on the second conveyor belt 310 when being transported.

[0085] Please refer to Figures 6 to 9 In this embodiment, the proofing device 3 further includes a plurality of proofing conveyor belts 390. The plurality of proofing conveyor belts 390 are stacked in the height direction and are arranged on a side of the third conveyor belt 330 away from the second conveyor belt 310.

[0086] In this embodiment, a plurality of proofing conveyor belts 390 are stacked in height, which can save space and form a heat-insulating and moisture-retaining transmission channel between the stacks, which is beneficial to the proofing of the dough. Secondly, the proofing conveyor belt 390 can be used as a proofing bed for the dough and can also be used to transfer the dough to the next process.

[0087] Specifically, the stacking quantity of the proofing conveyor belt 390 can be set according to the process requirements, such as the proofing time, the speed of the production line, etc.

[0088] In this embodiment, the proofing conveyor belt 390 is arranged perpendicularly to the third conveyor belt 330. A roller 391 and a rotating rod 392 are arranged at one end of the proofing conveyor belt 390 located at the top and close to the third conveyor belt 330. The roller 391 is arranged parallel to the width direction of the proofing conveyor belt 390. The rotating rod 392 is arranged above the roller 391 and is inclined toward the third conveyor belt 330. After the dough is guided by the rotating rod 392 and the roller 391, it can pass between the roller 391 and the top proofing conveyor belt 390. The roller 391 and the rotating rod 392 in this embodiment can conveniently guide the dough.

[0096] In this embodiment, annular bosses 427 are provided on both sides of the first roller 421, and both ends of the second roller 422 are limited between the two annular bosses 427. The two annular bosses 427 can be limited, so that the width of the dough embryo can be kept unchanged during the rolling process of the first roller 421 and the second roller 422.

[0097] In some embodiments, the mounting member 424 may be a bolt, and a screw hole is provided on the frame 410. The pre-compression amount of the spring 425 may be adjusted by the bolt, thereby adjusting the pressure applied by the second roller 422 to the dough blank and adjusting the floating range of the second roller 422.

[0098] Furthermore, two guide rollers 428 are arranged at the front side of the first rotating roller 421. The two guide rollers 428 are arranged vertically and spaced apart, and are connected to the frame 410, and the guide rollers 428 can rotate relative to the frame 410. The two guide rollers 428 correspond to the two sides in the width direction of the first rotating roller 421. In this way, the two guide rollers 428 can guide the dough embryo, so that the dough embryo enters between the two annular bosses 427 during the conveyance.

[0099] Please refer to Figures 10 to 12In this embodiment, the cutter assembly 430 includes a third roller 432, a knife holder 433 and a plurality of circular blades 431. The plurality of circular blades 431 are installed at intervals on the knife holder 433.
