[0027] The following will make a detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments.

[0028] The present invention provides a multi-functional automatic bread production line, as Figure 1 , 2 shown, which includes a feeding and conveying mechanism 1, a dough pressing mechanism 2, a dough rolling mechanism 3, a slitting mechanism 4, a dough rolling mechanism 5, a discharging and conveying mechanism 6, and a flour dusting mechanism 7 arranged in sequence. The conveyor belts of each mechanism are connected to each other to realize the conveying of the dough.

[0029] The fabric is conveyed into the noodle pressing mechanism 2 by the feeding and conveying mechanism 1. The noodle pressing mechanism 2 includes a first noodle pressing mechanism 21 and a second noodle pressing mechanism 22, and the fabric is pressed through multiple noodle pressing procedures to form a uniform sheet-like fabric. Powder sprinkling mechanisms 7 are provided on both the first noodle pressing mechanism 21 and the second noodle pressing mechanism 22. While pressing the fabric, the powder sprinkling mechanisms 7 sprinkle powder on the fabric, and the powder sprinkling can prevent the fabric from adhering to the device. After the fabric completes the noodle pressing step, it can enter the noodle rolling mechanism 3 for noodle rolling.

[0030] As Figure 3 shown, the noodle rolling mechanism 3 includes a noodle rolling workbench 31, a noodle rolling conveyor belt 32, a noodle rolling roller 33, a noodle rolling seat 34, and a noodle rolling motor 35. The noodle rolling conveyor belt 32, the noodle rolling roller 33, the noodle rolling seat 34, and the noodle rolling motor 35 are all arranged on the noodle rolling workbench 31. The noodle rolling conveyor belt 32 is driven by a driving component to rotate on the noodle rolling workbench 31 to convey the fabric.

[0031] The noodle rolling motor 35 and the noodle rolling roller 33 are rotatably arranged on the noodle rolling seat 34. The noodle rolling seat 34 is fixed on one side edge of the noodle rolling workbench 31. A positioning column 36 is provided on the noodle rolling seat 34. A positioning plate 37 is provided below the noodle rolling motor 35. An arc-shaped positioning groove 371 for the positioning column 36 to pass through is provided on the positioning plate 37. The noodle rolling motor 35 is movably arranged above the noodle rolling seat 34 through the positioning column 36. The output end of the noodle rolling motor 35 is connected to the tail end of the noodle rolling roller 33 through a connecting piece 38. The connecting piece 38 can be a crank or a belt. The noodle rolling motor 35 operates to drive the connecting piece 38 to drive the noodle rolling roller 33 to rotate clockwise.

[0032] The noodle rolling roller 33 is located above the noodle rolling conveyor belt 32 and is inclined with respect to the conveying direction of the noodle rolling conveyor belt 32. The roller diameter of the noodle rolling roller 33 gradually decreases from the head end to the tail end. Its surface has strip-shaped grooves 331 arranged along the length direction of the noodle rolling roller 33. Each strip-shaped groove 331 is relatively parallel and the interval between them is very small. The strip-shaped grooves 331 can rub against the fabric when contacting the fabric, thereby curling the fabric. In this embodiment, the noodle rolling roller 33 moves axially from the outside of the noodle rolling conveyor belt 32 towards the center direction of the noodle rolling conveyor belt 32. The noodle rolling roller 33 and the noodle rolling conveyor belt 32 cooperate to curl the passing sheet-like fabric into a columnar fabric.

[0033] In order to keep the winding roller 33 stable during the winding operation, avoid deviation, and affect the accuracy of winding, a locking assembly 39 for fixing the winding roller 33 is also provided in this case. The locking assembly 39 is located above the winding roller 33. The locking assembly 39 includes a lead screw 391 and a crank 392. One end of the lead screw 391 is connected to the positioning plate 37, and the other end is connected to the crank 392. Manually rotating the crank 392 drives the lead screw 391 to rotate to lock the winding roller 33. When it is necessary to adjust the inclination angle of the winding roller 33, reversing the rotation of the crank 392 can release the locking mechanism. At this time, the winding roller 33 can be adjusted. After the adjustment is completed, it can be locked again to perform the subsequent winding work.

[0034] When the winding conveyor belt 32 conveys the strip-shaped fabric to the lower part of the winding roller 33, the roller surface of the winding roller 33 contacts and rubs against the edge of the strip-shaped dough, causing the dough to curl and form a columnar fabric. The winding mechanism 3 can also curl the fabric laid with fillings. During the curling process of the strip-shaped dough, the fillings attached to its upper surface will be wrapped to form a sandwiched noodle column. After the fabric completes the winding step, it can enter the cutting mechanism 4.

[0035] As Figures 4 to 5 shown, the cutting mechanism 4 includes a cutting workbench 41, a cutting conveyor belt 42, a cutting assembly 43, and a cutting drive assembly 44. The cutting conveyor belt 42, the cutting assembly 43, and the cutting drive assembly 44 are all arranged on the cutting workbench 41. The cutting conveyor belt 42 is driven by a driving mechanism to rotate on the cutting workbench 41 to convey the fabric. The cutting assembly 43 is vertically arranged above the cutting conveyor belt 42. The cutting drive assembly 44 is connected to the cutting assembly 43 and drives the cutting assembly 43 to perform vertical reciprocating motion. A non-sticking assembly 45 is provided below the cutting assembly 43.

[0036] In this embodiment, a cutting mounting frame 47 is provided above the cutting conveyor belt 42 on the cutting workbench 41. The cutting mounting frame 47 includes a horizontal mounting frame 471 and a vertical mounting frame 472. The cutting drive assembly 44 is installed on the horizontal mounting frame 471. There is a slide rail 473 arranged along the length direction of the vertical mounting frame 472 on the vertical mounting frame 472. The cutting assembly 43 is slidably arranged on the slide rail 473.

[0037] The slitting assembly 43 includes a cutting knife 431 and a connecting block 432. The two ends of the connecting block 432 are respectively connected to the cutting knife 431 and the slitting drive assembly 44. When the slitting drive assembly 44 works, the cutting knife 431 makes a vertical reciprocating motion along with the rotation of the connecting block 432. A front fixing plate 433 and a rear fixing plate 434 are provided on the cutting knife 431. The back surface of the rear fixing plate 434 is connected to the slide rail 473, and the front surface of the rear fixing plate 434 is connected to the connecting block 432. The front fixing plate 433 and the rear fixing plate 434 are buckled to fix the cutting knife 431 on the connecting block 432. The slitting drive assembly 44 drives the connecting block 432 to rotate, and the connecting block 432 drives the cutting knife 431 to make a reciprocating motion along the length direction of the mounting frame, so as to realize the cutting of the fabric. The setting of the front and rear fixing plates makes the installation of the cutting knife 431 more stable, and at the same time can play a protective role for the cutting knife 431.

[0038] Since the fabrics containing moisture all have a certain stickiness, when the cutting knife 431 cuts the fabric, the cutting knife 431 is likely to adhere to the part with higher humidity inside the fabric and lift the dough. The dough is lifted by the adhesion, and its shape will change. Moreover, part of the fabric is adhered to the cutting knife 431, which will also reduce the weight of a single dough, thus affecting the weight of each single dough. If the dough is adhered to the cutting knife 431 and cannot fall, it will also affect the subsequent slitting work. To solve these problems above, the slitting mechanism 4 of this case also sets an anti-adhesion component 45. The anti-adhesion component 45 is arranged below the cutting knife 431 and above the slitting conveyor belt 42. The anti-adhesion component 45 includes two first rollers 451 and second rollers 452 arranged in parallel. There is a gap between the first roller 451 and the second roller 452. When the cutting knife 431 makes a reciprocating motion, it passes through the gap between the first roller 451 and the second roller 452. Limit plates 46 are provided at both ends of the first roller 451 and the second roller 452. Two strip-shaped limit slots 461 extending along the height direction of the limit plate 46 are opened on the limit plate 46. The roller shafts of the first roller 451 and the second roller 452 are arranged in the limit slots 461 and can slide up and down in the limit slots 461.

[0039] The cutting knife 431 moves downward through the gap between the first roller 451 and the second roller 452 to cut the fabric. After the cutting is completed, the cutting knife 431 moves upward. At this time, the dough adhered to the cutting knife 431 is blocked by the two rollers and falls freely, avoiding the situation of being lifted by the cutting knife 431. Since the two rollers are rotatably arranged, the acting force on the dough will not be very large and will not cause the dough to deform. This case also sets a temperature control device 48. The temperature control device 48 is electrically connected to the cutting knife 431 and controls the temperature of the cutting knife 431, so that the dough is not easily adhered to the cutting knife 431.

[0040] The slitting mechanism 4 is externally sleeved with a slitting machine housing 49 to improve the safety of the device. Heat dissipation holes 491 are provided on the peripheral side of the slitting machine housing 49 to effectively dissipate heat from the device and ensure the normal operation of the device. The fabric after slitting enters the strip rolling mechanism 5 for strip rolling and shaping.

[0041] As Figures 6 to 8 shown, the strip rolling mechanism 5 includes a strip rolling workbench 51, a strip rolling conveyor belt 52, a left strip rolling synchronous belt 53 and a right strip rolling synchronous belt 54 arranged on the strip rolling workbench 51. The left strip rolling synchronous belt 53 and the right strip rolling synchronous belt 54 are respectively located on the left and right sides above the strip rolling conveyor belt 52. The left strip rolling synchronous belt 53 and the right strip rolling synchronous belt 54 are transmitted in the same direction and have different transmission speeds. The transmission directions of the lower belts of the left strip rolling synchronous belt 53 and the right strip rolling synchronous belt 54 are the same as the transmission direction of the upper belt of the strip rolling conveyor belt 52.

[0042] A strip rolling left motor 531, a left driving wheel 532 and a left driven wheel 533 are provided on the left strip rolling synchronous belt 53. The output end of the strip rolling left motor 531 is connected to the left driving wheel 532. A strip rolling right motor 541, a right driving wheel 542 and a right driven wheel 543 are provided on the right strip rolling synchronous belt 54. The output end of the strip rolling right motor 541 is connected to the right driving wheel 542.

[0043] The distance between the left driving wheel 532 and the left driven wheel 533 is slightly greater than the distance between the right driving wheel 542 and the right driven wheel 543. The length of the left strip rolling synchronous belt 53 is slightly less than the length of the right strip rolling synchronous belt 54. Therefore, the transmission speed of the left strip rolling synchronous belt 53 is slightly higher than that of the right strip rolling synchronous belt 54. In this case, the left strip rolling synchronous belt 53 and the right strip rolling synchronous belt 54 are set to have different transmission speeds, and the transmission speed of the left strip rolling synchronous belt 53 is slightly greater than that of the right strip rolling synchronous belt 54. By using the speed difference between the two and cooperating with the strip rolling conveyor belt 52, the twisting degrees of both ends of the passing columnar fabric are different, so as to roll the columnar fabric into a twist shape and realize the strip rolling and shaping of the fabric.

[0044] Since the synchronous belt is relatively soft and its long distance is suspended, there is no object to support the middle part, which is easy to deform and affect the strip rolling effect. Therefore, in this case, a long strip pressing block 55 is provided on the inner surface of the lower belt of the left strip rolling synchronous belt 53 and the inner surface of the lower belt of the right strip rolling synchronous belt 54. The long strip pressing block 55 can press the relatively soft and easily deformable synchronous belt, so that the lower belt of the synchronous belt is parallel to the strip rolling conveyor belt 52 below to ensure uniform rubbing of the fabric.

[0045] A left dough rolling motor 531 is externally provided with a left protective cover 534. A left dough rolling synchronous belt 53 is located outside the left protective cover 534. A right dough rolling motor 541 is externally provided with a right protective cover 544. A right dough rolling synchronous belt 54 is located outside the right protective cover 544. Above the left protective cover 534 and the right protective cover 544, the dough rolling workbench 51 is provided with two parallel fixing frames 56. Along the length direction of the fixing frame 56, a strip-shaped groove 562 is provided on the fixing frame 56. At positions corresponding to the strip-shaped groove 562 on the left protective cover 534 and the right protective cover 544, adjusting members 57 are provided. The adjusting members 57 cooperate with the strip-shaped groove 562 to movably arrange the left protective cover 534 and the right protective cover 544 on the fixing frame 56. By adjusting the adjusting members 57, the left protective cover 534 and the right protective cover 544 can be moved, so as to adjust the distance between the left dough rolling synchronous belt 53 and the right dough rolling synchronous belt 54 to adapt to fabrics of different widths.

[0046] At both ends of the fixing frame 56, the dough rolling workbench 51 is provided with supporting members 58. The upper ends of the supporting members 58 are screw rods 581. At positions corresponding to the screw rods 581 on the fixing frame 56, through holes 561 are opened. The screw rods 581 cooperate with the through holes 561 to install the left protective cover 534 and the right protective cover 544 on the dough rolling workbench 51. At the same time, the height of the left protective cover 534 and the right protective cover 544 can be adjusted by rotating nuts, so as to adjust the height distance between the left dough rolling synchronous belt 53, the right dough rolling synchronous belt 54 and the dough rolling conveyor belt 52. The distance adjustment between the synchronous belts and the dough rolling conveyor belt 52 can adapt to fabrics of different thicknesses.

[0047] The working process of the bread production line is as follows:

[0048] First, the rough sheet-shaped fabric is fed into the dough pressing mechanism through the feeding conveyor mechanism 1. After being repeatedly pressed by the first dough pressing mechanism 21 and the second dough pressing mechanism 22, a uniform sheet-shaped fabric is formed. Then, the sheet-shaped fabric is conveyed to the lower part of the coiling roller 33 through the coiling conveyor belt 32. The rotating coiling roller 33 contacts and rubs against the edge of the sheet-shaped fabric to coil the sheet-shaped fabric into a whole strip-shaped fabric. The strip-shaped fabric is conveyed into the cutting mechanism by the cutting surface conveyor belt. When passing under the cutting knife 431, the cutting knife 431 makes a vertical reciprocating motion to cut the strip-shaped fabric into individual small strip-shaped fabrics. The cut individual strip-shaped fabrics are conveyed into the dough rolling mechanism 5 by the dough rolling conveyor belt 52. The two ends of the strip-shaped fabric respectively contact the left dough rolling synchronous belt 53 and the right dough rolling synchronous belt 54. By using the speed difference between the left and right synchronous belts, the strip-shaped fabric is rolled into a twist shape and then sent out by the discharging conveyor mechanism 6.

[0049] The above are only the preferred embodiments of the present invention, and do not limit the design of this case. All equivalent changes made according to the key design of this case fall within the protection scope of this case.
