Technical Field
[0001] The present application relates to the technical field of food processing equipment, and in particular to a bread dough shaping production line. Background Art
[0002] In the food industry, especially in the production of baked goods such as bread and pastries, traditional manual operation methods are gradually unable to meet the efficiency and quality requirements of modern industrial production. With the advancement of automation technology, more and more companies are trying to combine traditional processes with modern technology to improve production efficiency and product quality by improving the automation level of production lines, thereby achieving industrial upgrading. This not only helps to reduce production costs, but also maintains product consistency and stability, which is of great significance to improving corporate competitiveness.
[0003] In the dough shaping process, in order to realize the automated processing flow from raw materials to finished products, the traditional method usually includes multiple steps such as manual kneading, rolling, cutting and rolling. In order to improve production efficiency, the industry has tried to use various mechanical equipment to replace some manual operations, such as using rolling machines for preliminary shaping, cutting equipment to complete size cutting, and flattening machines to reduce the volume of dough. In addition, there are also plans to use manipulators or multi-axis robots to simulate manual operations to achieve precise dough shaping.
[0004] However, the above-mentioned automation solution has the problem of high mechanical structure complexity. At the same time, since the dough is easily deformed under force, the operation of transferring the dough raw materials to various process equipment is not only technically difficult to achieve, but also the corresponding equipment investment cost and maintenance cost are also high. The existing technology still has certain difficulties in realizing the full automation of the bread dough processing process. How to reduce costs while ensuring processing quality has become a key issue that needs to be solved urgently. Summary of the invention
[0005] In order to improve the degree of automation in bread dough production and reduce production costs while ensuring processing quality, the present application provides a bread dough shaping production line.
[0006] The present application provides a bread dough shaping production line, which adopts the following technical solution: A bread dough shaping production line comprises a frame, on which are arranged: A hopper, the hopper is located at a high position and is connected to each other from top to bottom, and the cross section of the hopper gradually decreases from top to bottom; An automatic feeding device, the automatic feeding device is located at one side of the hopper and is used to automatically transfer the bread dough into the hopper, the automatic feeding device comprises a lifting mechanism, a turning mechanism and a receiving guide plate, the lifting mechanism and the turning mechanism are located at the same side of the hopper, and the turning mechanism is located directly above the lifting mechanism, the lifting mechanism is used to lift a material box containing bread dough to the position of the turning mechanism, the turning mechanism is used to receive the lifted material box and turn it in the direction of the hopper, the receiving guide plate is inclined and turns with the turning of the turning mechanism, when the turning mechanism needs to receive the material box, the lower end of the receiving guide plate is fixed on the turning mechanism, and the high end of the receiving guide plate is inclined toward the direction of the hopper, when the turning mechanism drives the material box to turn over, the end of the receiving guide plate connected to the turning mechanism is the high end, and the other end of the receiving guide plate is located at the upper end opening of the hopper; An automatic material dividing device, the automatic material dividing device is located at the bottom of the hopper and is used to divide the bread dough in the hopper into equal parts; An automatic stripping device, located below the automatic material dividing device, for pressing the bread dough cut into strips; An automatic segmenting device, located below the automatic strip-pressing device, for receiving and conveying strips of bread dough and performing segmentation operations on them; An automatic rolling device, which is arranged behind the automatic segmenting device in the conveying direction and is used for rolling the strip-shaped bread dough into a ball; A material receiving box is located behind the automatic rolling device in the conveying direction and is used for receiving the rolled bread dough.
[0007] By adopting the above technical scheme, when the bread dough needs to be rolled, the staff only needs to place the material box containing the bread dough in the lifting mechanism, the lifting mechanism lifts the material box containing the bread dough to the position of the flipping mechanism, and then the flipping mechanism receives the material box containing the bread dough and flips it in the direction of the hopper. During the flipping process of the material box, the bread dough rolls out of the material box under the action of gravity and is guided into the hopper through the receiving guide plate, thereby realizing automatic feeding of the bread dough into the hopper without manual handling. When the bread dough falls into the hopper, the automatic dividing device first seals the bottom of the hopper. Since the cross-section of the hopper gradually decreases from top to bottom, the soft bread dough fills the bottom of the hopper under the action of gravity, and then the automatic dividing device divides the bread dough. The bread dough is cut into equal parts, and the bread dough after being cut into equal parts falls into the automatic stripping device, which presses the bread dough into strips. The bread dough in strips falls into the automatic segmenting device, which receives and segments the bread dough in strips. The segmented bread dough in strips is transported to the automatic rolling device, which rolls the bread dough in strips into balls to form finished bread dough products, and finally transports them to the receiving box for receiving. The whole production process of bread dough has a high degree of automation. The staff only needs to place the material box containing the bread dough raw materials in the lifting mechanism. All the processes are completed by the automatic device in the middle. Continuous operation is conducive to improving the production efficiency of bread dough, and the mechanical structure is simple, which reduces the production cost while ensuring the processing quality.

[0011] By adopting the above technical solution, when the lifting mechanism lifts the material box into the flip frame, the support member supports the material box, thereby realizing the transfer of the material box from a low place to a high place, and then the second driving member drives the flip frame to flip in the direction of the hopper. The bread dough in the material box is poured out from the material box under the action of gravity and flipping force, and automatically falls into the hopper through the inclined downward state of the receiving guide plate.

When the fourth driving member drives the dividing roller to rotate, the dividing knife located above divides the bread dough at the bottom of the hopper, and the small bread dough after dividing falls downward into the automatic stripping device under the push of the dividing knife for stripping operation. Since the bottom of the hopper is always filled with bread dough, the volume of the bread dough divided by the dividing knife each time it rotates remains unchanged, which is beneficial to improve the consistency of the bread dough product.
[0016] Preferably, the automatic battering device includes a first conveying mechanism and a pressure mechanism. The first conveying mechanism is arranged on the frame and located below the automatic material dividing device for receiving and conveying the bread dough after the material dividing operation.

[0020] Preferably, the second conveying mechanism is provided with a stripping mechanism for dividing the strips of bread dough into two, the stripping mechanism includes a supporting roller, a stripping wheel cutter and two transition belts, the supporting roller is rotatably connected to the frame, and the top of the supporting roller is flush with the conveying plane of the second conveying mechanism, the stripping wheel cutter is rotatably connected to the frame and is located directly above the supporting roller, the blade of the stripping wheel cutter abuts against the top of the supporting roller, the two transition belts are respectively arranged on both sides of the stripping wheel cutter, and the two transition belts are located behind the stripping wheel cutter to respectively receive and convey the two strips of bread dough after stripping, and the pressing and cutting mechanism is provided with a weighing piece for weighing the strips of bread dough after stripping, and the weighing piece is electrically connected to the pressing and cutting mechanism.

The slitting wheel knife divides the strip-shaped bread dough into two strips, and the two strips of bread dough are respectively conveyed to the pressing and cutting mechanism through two transition belts. The weighing piece in the pressing and cutting mechanism weighs the cut bread dough. When the weight reaches the standard, the weighing piece sends an electrical signal to the pressing and cutting mechanism, so that the pressing and cutting mechanism performs a pressing and cutting operation on the cut bread dough, so that each bread dough is of standard weight, and it is beneficial to improve the production efficiency of the bread dough.
[0022] Preferably, the diameter of the supporting roller gradually decreases from the middle to both ends, and the gap between the two transition zones gradually increases in the direction away from the slitting wheel cutter.
[0023] By adopting the above technical solution, the diameter of the support roller gradually decreases from the middle to the two ends, so that the two bread balls cut by the slitting wheel knife continue to be transported backward in a direction gradually moving away from each other, and the gap between the two transition zones gradually increases in the direction away from the slitting wheel knife to adapt to the two bread balls that are gradually separated, which helps to avoid the two bread balls that are cut from sticking together again during the transportation process.

By setting a lifting mechanism, a turning mechanism and a receiving guide plate, the lifting mechanism lifts the material box containing the bread dough to the position of the turning mechanism, and then the turning mechanism receives the material box containing the bread dough and turns it in the direction of the hopper. During the turning process of the material box, the bread dough rolls out of the material box due to gravity and the turning force, and is guided into the hopper through the receiving guide plate, thereby realizing automatic loading of the bread dough into the hopper without manual handling. The structure is simple and the degree of automation is improved.
[0027] 2. By setting the support bar and the third driving member, when the material box needs to be lifted into the flip frame, the third driving member drives the support bar to rotate so that the other end of the support bar faces the outside of the flip frame. In this state of the support bar, the material box is lifted into the flip frame for avoidance.

Since the bottom of the hopper is always filled with bread dough, the volume divided by the dividing knife each time it rotates remains unchanged, which is beneficial to improve the consistency of the bread dough product.

The automatic feeding device 3 is located on one side of the hopper 2 and is used to automatically transfer the bread dough to the hopper 2. The automatic material dividing device 4 is located at the bottom of the hopper 2 and is used to divide the bread dough in the hopper 2 into equal amounts. The automatic layering device 5 is located below the automatic material dividing device 4 and is used to divide the dough into equal amounts. The bread dough is pressed into strips, and the automatic segmenting device 6 is located below the automatic strip-pressing device 5 for receiving and conveying the strip-shaped bread dough and segmenting it. The automatic rolling device 7 is arranged behind the conveying direction of the automatic segmenting device 6 for rolling the strip-shaped bread dough into a ball. The material receiving box 8 is located behind the conveying direction of the automatic rolling device 7 for receiving the rolled bread dough. In the entire production process of the bread dough, all the steps are completed by the automated device with a high degree of automation and continuous operation, which is beneficial to improving the production efficiency of the bread dough, and has a simple mechanical structure, which reduces the production cost while ensuring the processing quality.
[0040] Reference Figure 1 and Figure 3The automatic feeding device 3 includes a lifting mechanism 31, a turning mechanism 32 and a receiving guide plate 33. The lifting mechanism 31 and the turning mechanism 32 are located on the same side of the hopper 2, and the turning mechanism 32 is located directly above the lifting mechanism 31. The lifting mechanism 31 is used to lift the material box containing the bread dough to the position of the turning mechanism 32, and the turning mechanism 32 is used to receive the lifted material box and turn it in the direction of the hopper 2. The receiving guide plate 33 is inclined and turns with the turning of the turning mechanism 32. When the turning mechanism 32 needs to receive the material box, the lower end of the receiving guide plate 33 is fixed on the turning mechanism 32, and the high end of the receiving guide plate 33 is inclined toward the direction of the hopper 2. When the turning mechanism 32 drives the material box to turn over, the end of the receiving guide plate 33 connected to the turning mechanism 32 is the high end, and the other end of the receiving guide plate 33 is located at the upper end opening of the hopper 2. When the bread dough needs to be loaded, the staff only needs to place the material box containing the bread dough in the lifting mechanism 31 located at the lower end. The lifting mechanism 31 lifts the material box containing the bread dough to the flipping mechanism 32. The flipping mechanism 32 drives the material box to flip in the direction of the hopper 2, so that the bread dough in the material box rolls into the hopper 2 through the receiving guide plate 33 under the action of gravity and flipping force.
[0041] Reference Figure 1 and Figure 3 The lifting mechanism 31 includes a lifting plate 311 and a first driving member 312. The lifting plate 311 is horizontally arranged on one side of the hopper 2, and the cross section of the lifting plate 311 is smaller than the bottom surface of the material box. When the material box is placed on the lifting plate 311, the bottom edge of the material box extends from the side of the lifting plate 311. The first driving member 312 is arranged on the frame 1 to drive the lifting plate 311 to move vertically up and down, so as to drive the material box on the lifting plate 311 to move from a low position to a high position on one side of the hopper 2. In this embodiment, the first driving member 312 uses a driving motor and a screw rod to drive the lifting plate 311, and the driving motor and the screw rod are hidden in the frame 1, which will not be described in detail. In other embodiments, the first driving member 312 can also use other driving methods, as long as it can drive the lifting plate 311 to move vertically up and down.

The support member 322 is arranged on the bottom peripheral side of the flipping frame 321 to receive the lifted material box. The second driving member 323 is arranged on the frame 1 to drive the flipping frame 321 to flip in the direction of the hopper 2. In the present embodiment, the second driving member 323 is selected as a driving motor and a rotating shaft to realize the flipping of the flipping frame 321. The driving motor and the rotating shaft are also hidden in the frame 1 and are not described here. When the flipping operation of the flip frame 321 is completed, the high end of the receiving guide plate 33 is fixedly connected to the side wall of the flip frame 321, and the low end of the receiving guide plate 33 is inclined downward to extend to the upper opening of the hopper 2, so that the bread dough in the material box can roll into the hopper 2 through the inclined receiving guide plate 33 under the action of gravity and roll force.

The support bar 3221 is parallel to the flip frame 321, and one end of the support bar 3221 is located directly below the edge of the flip frame 321. The third driving member is arranged at the edge of the flip frame 321 to drive the support bar 3221 to rotate around its end connected to the third driving member. In this embodiment, the third driving member is configured as a rotating cylinder 3222, which is vertically fixed at the end corner of the bottom of the flip frame 321. One end of the support bar 3221 is fixedly connected to the rotating shaft of the rotating cylinder 3222. When the lifting mechanism 31 lifts the lifting plate 311, the rotating cylinder 3222 drives the support bar 3221 to rotate until the other end thereof faces the outside of the flip frame 321, so as to achieve the avoidance of the material box entering the flip frame 321. When the material box enters the flip frame 321, the rotating cylinder 3222 drives the support bar 3221 to rotate until the other end thereof faces the inside of the flip frame 321. At this time, the four support bars 3221 are located at the bottom of the four end corners of the material box for support, thereby realizing the transfer of the material box from the lifting mechanism 31 to the flip mechanism 32.

The bread dough conveyed from the first conveyor belt 513 falls into the gap between the pressure rollers on the fixed roller group 521 and the pressure rollers on the movable roller group 522. When the bread dough falls downward, the pressure rollers on the fixed roller group 521 and the pressure rollers on the movable roller group 522 press the bread dough so that the bread dough forms a strip shape during the falling process. It should be noted that the movable roller group 522 can move toward or away from the fixed roller group 521 to adjust the thickness of the strip bread dough, and the pressure rollers on the fixed roller group 521 and the movable roller group 522 are arranged crosswise in the vertical direction to improve the uniformity of the thickness of the strip bread dough.

The blade of the slitting wheel knife 92 abuts against the top of the supporting roller 91. During the conveying of the strips of bread dough on the second conveyor belt 613, the slitting wheel knife 92 cuts the strips of bread dough along the length direction. The two transition belts 93 are respectively arranged on both sides of the slitting wheel knife 92, and the two transition belts 93 are located behind the slitting wheel knife 92 to respectively receive and convey the two strips of bread dough after slitting, so as to improve the production efficiency of the bread dough.
[0049] Reference Figure 6 and Figure 7 The diameter of the support roller 91 gradually decreases from the middle to the two ends. At the same time, the gap between the two transition zones 93 gradually increases in the direction away from the slitting wheel knife 92, so that the two strips of bread are gradually separated after being cut, so as to avoid the two strips of bread sticking together again during the conveying process.
[0050] Reference Figure 5 and Figure 6The pressing and cutting mechanism 62 includes a pressing and cutting knife 621 and a fifth driving member 622. The pressing and cutting knife 621 is located directly above the second conveyor belt 613. The fifth driving member 622 is arranged on the frame 1 to drive the pressing and cutting knife 621 to move vertically up and down. In this embodiment, the fifth driving member 622 is driven by a cylinder. It is worth mentioning that a weighing piece is arranged in the pressing and cutting mechanism 62 for weighing the strips of bread dough after being cut. The weighing piece is electrically connected to the pressing and cutting mechanism 62. When the strips of bread dough after being cut are conveyed to the position of the weighing piece, the weighing piece measures the weight of the strips of bread dough in real time. When the weight reaches the standard, the weighing piece sends an electrical signal to the pressing and cutting mechanism 62, so that the pressing and cutting mechanism 62 performs a pressing and cutting operation on the strips of bread dough, so that each bread dough is of standard weight.
[0051] Reference Figure 6 A flattening mechanism for flattening the strip-shaped bread dough is arranged between the automatic segmenting device 6 and the automatic rolling device 7. The flattening mechanism includes a plurality of flattening rollers 10 arranged along the conveying direction. In the present embodiment, the number of the flattening rollers 10 is set to three. The three flattening rollers 10 are all rotatably connected to the frame 1, and the gap between the three flattening rollers 10 and the conveying plane gradually decreases along the conveying direction.
[0052] Reference Figure 6 and Figure 8 The automatic rolling device 7 includes a rolling net 71, two brackets 72 and fixings. The two brackets 72 are fixed on the frame 1 at intervals horizontally. The two ends of the rolling net 71 are respectively fixedly connected to the two brackets 72 by fixings, so that the vertical section of the rolling net 71 is set in a concave arc. In this embodiment, the fixings are fastening bolts 73, which are movably passed through the ends of the rolling net 71 and then threadedly penetrated into the brackets 72 to achieve the fixation of the two ends of the rolling net 71. When the strip of bread passes through the rolling net 71, the end of the strip of bread contacts the rolling net 71 and rolls up, and as the strip of bread is continuously conveyed, the strip of bread is continuously rolled to form a finished bread dough. The finished bread dough passes through the rolling net 71 and is conveyed to the receiving box 8 for collection.
[0053] The implementation principle of a bread dough shaping production line of the embodiment of the present application is as follows: when it is necessary to shape the bread dough, the staff only needs to place the material box containing the bread dough on the lifting plate 311 located at a lower position, and the first driving member 312 drives the lifting plate 311 to drive the material box to move vertically upward into the flip frame 321, and the four rotating cylinders 3222 respectively drive the four supporting bars 3221 to rotate until the other end thereof faces the inner side of the flip frame 321, and the four supporting bars 3221 are located at the bottom of the four end corners of the material box The second driving member 323 then drives the flip frame 321 to flip toward the hopper 2. When the flipping operation of the flip frame 321 is completed, the high end of the receiving guide plate 33 is fixedly connected to the side wall of the flip frame 321, and the low end of the receiving guide plate 33 extends downwardly to the upper opening of the hopper 2. The bread dough in the material box rolls into the hopper 2 under the action of gravity and the roll force. At this time, the dividing roller 41 does not rotate, and the two dividing rollers 41 at the top do not rotate. The tip of the material knife 42 abuts against the edge of the opening at the lower end of the hopper 2 to seal the lower end of the hopper 2, and then the material dividing roller 41 rotates 120 degrees each time, so that the two material dividing knives 42 located above divide the bread dough in the hopper 2 equally each time, and the divided bread dough falls downward to the first conveyor belt 513 for transportation. The first conveyor belt 513 conveys the bread dough to the gap between the fixed roller group 521 and the movable roller group 522, and the layering rollers on the fixed roller group 521 and the layering rollers on the movable roller group 522 divide the bread dough. The bread dough is pressed so that it forms strips during the falling process, and the strips of bread dough fall onto the second conveyor belt 613 for further conveyance. During the conveyance of the strips of bread dough on the second conveyor belt 613, the stripping wheel cutter 92 divides the strips of bread dough into two, and performs segmentation operation after the weight is measured by a weighing piece, so that the weight of each strip of bread dough is consistent, and then the strips of bread dough pass through three flattening rollers 10 for flattening operation, and then pass through the rolling net 71 to form finished bread dough, which is finally collected in the receiving box 8. In the entire shaping process of the bread dough, the degree of automation is high and the operation continuity is strong, which is conducive to improving the production efficiency of the bread dough, and the mechanical structure is simple, which reduces the production cost while ensuring the processing quality.
[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
