DETAILED DESCRIPTION

[0024] In order to facilitate the understanding of the present application, the present application will be described in more detail below with reference to the relevant drawings, which show several embodiments of the present application. However, the present application can be realized in different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0025] It should be noted that when an element is referred to as being "fixedly attached" to another element, it can be directly on the other element or there can be intervening elements. When an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements can be present. The terms "vertical", "horizontal", "left", "right", and the like as used herein are used for explanation purposes only.

[0026] Please refer to the drawings Figures 1-6 A steamed bun and steamed dumpling combined machine comprises a main conveying table 1.

[0027] The main conveying table 1, as the basic bearing and conveying component of the device, is used for conveying dough sheets. A roller cutting group 2 is installed above one end of the conveying table 1 for continuously cutting the dough sheets. A tubular forming area 3 is arranged on one side of the roller cutting group 2 for folding the flattened dough sheets into a tubular shape. A material pushing box 4 is arranged on one side of the tubular forming area 3 for pushing the material. A dough sheet pretreatment assembly 6 is installed above the other end of the main conveying table 1 for cutting the edges of the initially fed dough sheets and blocking the broken dough pieces. A special oiling assembly for steamed buns 5 is arranged on one side of the dough sheet pretreatment assembly 6 for applying oil to the flattened dough sheets when producing steamed buns.

[0028] A broken material collecting groove 7 is arranged below the main conveying table 1 at the positions corresponding to the dough sheet pretreatment assembly 6 at both ends of the main conveying table 1 for receiving the cut edges of the dough sheets blocked by the dough sheet pretreatment assembly 6.

[0029] The stuffing conveying bin 10 is arranged on one side of the outer wall of the main conveying table 1, between the tubular forming area 3 and the material pushing box 4, and is used for conveying stuffing to the surface of the main conveying table 1.

[0030] In the embodiment, as shown in the figure, Figure 1 The bottom of the main conveying table 1 is provided with a moving table 8 through a linear motor, and the moving table 8 is detachably provided with a kneading and cutting circular cutter 9 on one side. The kneading and cutting circular cutter 9 forms a horizontal transmission structure through the moving table 8 on the bottom of the main conveying table 1 close to one side of the roller pressing and cutting group 2.

[0031] Through the above structure, when producing steamed buns, the kneading and cutting circular cutter 9 is located below the dough sheet roller pressing and cutting group 2, which is aligned with the stuffing tubular dough conveying path, meeting the kneading and cutting requirements. When producing steamed buns or twisted rolls, the kneading and cutting circular cutter 9 can be quickly moved horizontally away from the main conveying table 1 through the linear motor and the moving table 8, so as to quickly release the space below the main conveying table 1, which is convenient for docking the small conveying platform to receive steamed bun blanks and twisted roll blanks. This avoids the interference of the cutter on the production of non-steamed bun categories, saves the disassembly and assembly steps, greatly improves the switching efficiency of raw product categories and the space utilization rate of the equipment.

[0032] In the embodiment, as shown in the figure, Figure 3 The kneading and cutting circular cutter 9 includes a cutter body mounting seat 901, a guide turntable 902 and a driving gear 903. The cutter body mounting seat 901 is equiangularly and annularly distributed, one end of which is fixed to the inside of the kneading and cutting circular cutter 9 through a hexagon nut, and the other end is rotatably connected with a cutter. The guide turntable 902 is rotatably connected to the inside of the kneading and cutting circular cutter 9, and the top of the guide turntable 902 is slidably matched with the annular edge through an embedded sliding slot.

[0033] Through the above structure, the cutter body mounting seat 901 is fixed through the hexagon nut, which can ensure uniform arrangement and stable installation of multiple cutters, and can also adjust the cutter installation position to adapt to stuffing tubular dough of different diameters and realize flexible adjustment of steamed bun raw size.

[0034] In the embodiment, as shown in the figure, Figure 3 The driving gear 903 is rotatably connected to the inside of the kneading and cutting circular cutter 9 through a servo motor, and the guide turntable 902 is provided with a sawtooth structure meshing with the driving gear 903 on one side edge close to the driving gear 903. The guide turntable 902 is located above each cutter in an annular distribution, and a limiting guide groove is formed through the surface of the guide turntable 902. Each cutter is provided with a pin at a position corresponding to the limiting guide groove, and the pin penetrates the corresponding limiting guide groove above it.

[0035] Through the above structure, the active gear 903 is linked with the servo motor and, in conjunction with the meshing saw teeth of the guide turntable 902, enables the rotation of the guide turntable 902. Combined with the sliding cooperation between the limiting guide groove of the guide turntable 902 and the cutter pin, the circular motion can be transformed into the synchronous opening and closing motion of the ring cutter, ensuring uniform cutting size of the filled tubular dough and tight pinching of the end face.

[0036] In this embodiment, as Figure 1 and Figure 2 As shown, the tubular forming area 3 includes an inclined folding roller 301 and a bending guide roller 302. The bending guide roller 302 is symmetrically distributed. A drive motor is provided on one side of the inclined folding roller 301, and the roller body is inclined at 30-60°.

[0037] With the above structure, the inclined folding rollers 301 are inclined and driven by a motor. By means of the tilt angle and rotation, the edge of the sheet can be gradually folded to form a semi-tubular structure, laying the foundation for subsequent closure. Then, the symmetrically distributed curved guide rollers 302 guide the sheet, and both of them support position and height adjustment (which can be achieved by fixing the shaft with a hexagonal nut). The curved guide rollers 302 can also adjust the spacing to adapt to sheets of different thicknesses and widths, improve the adaptability of the equipment, and ensure the tubular forming effect of sheets of different specifications.

[0038] In this embodiment, as Figure 4 As shown, the material conveying box 4 is strip-shaped, wide at the top and narrow at the bottom, and has a reduced bottom shape. The material conveying box 4 is equipped with a material conveying roller 401 driven by a motor. The surface of the material conveying roller 401 has spiral grooves distributed along the axial direction. The bottom of the material conveying box 4 is equipped with an adjustable base plate 402. The adjustable base plate 402 is symmetrically distributed and slidably connected to the bottom of the material conveying box 4. A pattern pressing roller 11 is installed between the material conveying box 4 and the special oiling component 5 for flower rolls.

[0039] Through the above structure, the material conveying box 4 and the material conveying roller 401 are structurally coordinated. When not in operation, the material conveying roller 401 can fit against the bottom of the material conveying box 4. Even if the adjustable bottom plate 402 is opened, it will prevent the continuous leakage of internal materials. When in operation, the rotation of the material conveying roller 401 can accurately drive the material out through the slot. At the same time, the adjustable bottom plate 402 can flexibly adjust the opening and closing degree according to the size of the auxiliary material particles, adapting to different specifications of materials such as scallions and pepper powder, ensuring that the discharge volume is controllable.

[0040] In this embodiment, as Figure 5As shown, the special oiling component 5 for steamed buns includes a lifting adjustment frame 501 driven by a cylinder, an oil storage tank fixing frame 502, and brushes 503. The brushes 503 are symmetrically distributed about the vertical center line of the oil storage tank fixing frame 502. A servo motor is installed on the top of the lifting adjustment frame 501, and the top of the oil storage tank fixing frame 502 is fixedly connected to the output end of the servo motor. An oil tank for storing edible oil is detachably installed inside the oil storage tank fixing frame 502.

[0041] With the above structure, the pattern pressing rollers 11 installed between the special oiling components 5 for steamed buns can all be height-adjusted. This not only allows for flexible adaptation to the actual thickness of the dough sheet, but also, in the process of making steamed buns and dumplings, it can simultaneously raise both to a height higher than the dough sheet conveying path, avoiding obstruction or scratching of the dough sheet. The brushes 503 are symmetrically distributed, and when combined with the rotation of the oil storage tank fixing frame 502 driven by the servo motor, they can drive the brushes 503 to swing evenly along the surface of the dough sheet, ensuring that the dough surface below is evenly oiled without dead corners.

[0042] In this embodiment, as Figure 5 As shown, the brush 503 consists of an oil guide 5031 and an integrated sponge soft brush 5032. The oil guide 5031 is detachably installed at both ends of the bottom of the oil tank fixing frame 502. The interior of the oil guide 5031 is a hollow cavity with microporous structures distributed at the bottom. The exterior of the oil guide 5031 is connected to the oil tank inside the oil tank fixing frame 502 through a corrugated pipe. The top of the integrated sponge soft brush 5032 is tightly attached to and covers the bottom of the microporous structure.

[0043] With the above structure, the oil tank in the oil storage tank fixing frame 502 has a capacity of 100L and is equipped with an oil replenishment port. The oil guide component 5031 is connected to the oil tank through a corrugated pipe. With the bottom microporous structure, the edible oil can be evenly and continuously penetrated into the integrated sponge soft brush 5032, avoiding interruption of oil application or uneven oil volume. In addition, the oil guide component 5031 can be detached and installed, and is a modular component, which is convenient for later replacement.

[0044] In this embodiment, as Figure 2 As shown, the sheet pretreatment assembly 6 includes an edge cutting wheel 601 driven by a motor and a scrap blocking plate 602. The scrap blocking plate 602 is located between the special oiling assembly 5 for steamed buns and the edge cutting wheel 601. The inner edge of the scrap blocking plate 602 on the side near the cutting wheel is offset outward relative to the inner edge of the cutting blade of the cutting wheel by an offset of 1mm-3mm. The edge cutting wheels 601 are symmetrically distributed, and the main conveyor table 1 is equipped with a feeding guide roller assembly at the position corresponding to the edge cutting wheel 601. The edge cutting wheel 601 is detachably installed on one side of the frame of the feeding guide roller assembly.

[0045] With the above structure, the symmetrically distributed edge cutting wheels 601, paired with the corresponding feed guide roller group, can first limit the offset of the sheet by the roller group, and then the cutting wheels can accurately cut off the edge. The specifications of the scrap blocking plate 602 can intercept the cutting scrap to the greatest extent, prevent the scrap edge from moving forward with the sheet, and prevent it from scratching the edge of the regular sheet. At the same time, the main conveyor table 1 adopts a sloping channel in the area corresponding to the scrap blocking plate 602. With the continuous transmission of the main conveyor table, the continuously generated scrap can be automatically slid down the sloping channel to the scrap collection tank 7 under the action of thrust. There is no need for continuous manual cleaning of scrap, which greatly reduces the frequency of manual intervention and improves production continuity.

[0046] In this embodiment, as Figure 6 As shown, a spiral conveying screw is rotatably connected inside the filling conveying chamber 10, and the filling conveying chamber 10 is inclined at 15-45° on one side of the main conveying table 1. The filling conveying chamber 10 is conical in shape, and a filling discharge guide pipe 1001 is threadedly connected to the narrower end of its bottom. The filling discharge guide pipe 1001 is close to the side of the inclined folding roller 301. A cleaning wastewater discharge port 1002 is threadedly connected to the bottom of the filling conveying chamber 10.

[0047] With the above structure, the filling conveying chamber 10 has a capacity of 200kg. It is equipped with tempered glass viewing windows at both ends, which can monitor the remaining amount of filling in the chamber in real time and facilitate timely replenishment. Its inclined design, combined with the conical chamber body, can not only use gravity to assist the filling to flow to the narrower end at the bottom, avoiding the accumulation of filling in the chamber, but also achieve precise convergence of filling to the filling discharge guide pipe 1001 through the conical contraction, ensuring conveying efficiency. At the same time, the inclined layout, combined with the cleaning wastewater discharge interface 1002 with the bottom threaded connection, greatly improves the convenience of subsequent cleaning.

[0048] The specific operation process of this invention is as follows: When using this steamed bun, mantou, and flower roll combination machine, the initial equipment docking must be completed first. The external dough press is docked to the feeding side of the dough pretreatment component 6, and the small conveyor is docked below the dough roll cutting group 2 to ensure that the transmission direction of each device is consistent.

[0049] If making steamed buns, before turning on the power to the equipment, first adjust the special components. Using the lifting adjustment frame 501 of the special oiling component 5 for steamed buns, raise the brush 503 to a position 5-10mm higher than the dough conveying path to avoid obstructing the dough conveying. Use the hexagonal nut on the mounting frame of the patterned pressing roller 11 to adjust its height to be flush with the brush 503. Start the linear motor at the bottom of the main conveyor table 1 to make the moving table 8 drive the kneading and cutting circular cutter 9 to retract away from the main conveyor table 1.

[0050] When the external dough press presses the dough into a uniform sheet and conveys it to the main conveyor table 1, the sheet first enters the feeding end of the sheet pretreatment component 6. The symmetrically arranged feeding guide roller group here restricts the lateral displacement of the sheet by adhering to both sides of the sheet, ensuring that the sheet is driven along the center line of the main conveyor table 1. When the sheet contacts the symmetrically distributed edge cutting wheels 601, the edge cutting wheels 601 rotate under the drive of the motor, and their cutting blades contact the edge of the sheet and cut off the excess edge material, so that the two sides of the sheet form a flat edge.

[0051] The scrap generated from cutting continues to move forward under the transmission action of the main conveyor table 1 until it contacts the scrap blocking plate 602. The blocking plate is made of food-grade silicone material with a thickness of 3-5mm, and the bottom is 0.5mm away from the main conveyor table 1, which can prevent the scrap from moving forward. At the same time, the main conveyor table 1 has sloping guide openings on both sides corresponding to the scrap blocking plate 602. Under the push of the continuously generated scrap, the scrap gradually slides down along the guide openings into the scrap collection trough 7 below, which can complete the scrap recycling.

[0052] The neatly shaped dough sheet in the middle continues to be conveyed to the tubular forming area 3. During the first production run, manual assistance is required to complete the initial edge rolling. The operator holds a food-grade scraper and gently folds one edge of the dough sheet upward by 1-2 cm when the front end of the dough sheet enters under the inclined folding roller 301, so that it fits against the roller surface of the inclined folding roller 301. The inclined folding roller 301 rotates under the drive of the motor. With the help of the friction between the roller surface and the dough sheet, the folded edge continues to roll upward. At the same time, its 30-60° inclination angle causes the other edge of the dough sheet to gradually fold in sync, forming a semi-tubular structure. As the semi-tubular structure moves forward with the main conveyor table 1 and gradually transitions into a tubular structure, the good viscosity and extensibility of the dough allow the open edge of the tubular structure to naturally fit together and close tightly. Since no internal filling is injected, there is no support to hinder the closure. Finally, a solid tubular noodle structure is formed, and manual assistance can be stopped. The dough sheet continues to move forward with the main conveyor table 1, eventually forming a complete and continuous tubular noodle structure.

[0053] Symmetrically distributed bending guide rollers 302 guide the tubular surface structure forward within a defined range by adhering to the outer side of the semi-tubular surface sheet. It is then sent to the surface sheet roller cutting group 2, which consists of two sets of rollers at the front and rear and a cylinder-driven cutting blade in the middle. The active roller group adjacent to the bending guide rollers 302 is a symmetrical structure driven by a motor, and the other side is a driven roller group. The spacing of both sets of rollers can be changed by adjusting bolts to adhere to both ends of the tubular surface structure and achieve positioning.

[0054] The cylinder-driven cutting blade can adjust the pneumatic speed according to the required size of the steamed buns (pneumatic response time ≤ 0.2s). When the tubular surface structure is conveyed to the cutting position by the roller group, the cutting blade falls rapidly under the drive of the cylinder, cutting the continuous tubular structure into steamed bun blanks of the same size. The blanks are then conveyed to the subsequent processing stage by a small conveyor to complete the steamed bun production.

[0055] When the equipment is used to produce flower rolls, the initial equipment docking and dough pretreatment process is the same as that for steamed bun production. The difference is that the special components need to be adjusted accordingly. First, based on the thickness of the dough, the brush 503 of the special oiling component 5 for flower rolls is lowered to a state that is in contact with the surface of the dough through the lifting adjustment frame 501. At the same time, the height of the pattern pressing roller 11 is adjusted so that the gap between the roller surface and the surface of the dough is ≤1mm.

[0056] Fill the material delivery box 4 with auxiliary materials for steamed buns (such as chopped green onions, Sichuan peppercorn powder, etc.) to ensure that the auxiliary materials fill the space inside the box. At the same time, add cooking oil to the oil tank of the oil storage tank fixing frame 502. After the power is turned on, the initial dough sheet pretreatment process is the same as that for steamed bun production. When the dough sheet is conveyed to the bottom of the special oiling component 5 for steamed buns, the oil storage tank fixing frame 502 rotates 180° reciprocating under the drive of the servo motor, driving the brush 503 to rotate at a uniform speed along the surface of the dough sheet. Since the oil tank and the oil guide 5031 are a through structure, and the bottom of the oil guide 5031 is provided with a microporous structure (pore diameter 0.5-1mm), the cooking oil can continuously penetrate into the integrated sponge soft brush 5032 through the micropores, ensuring that the brush 503 remains moist during the oiling process and achieves uniform oiling.

[0057] After being coated with oil, the dough sheet continues to be conveyed to the bottom of the pattern pressing roller 11. Since the pattern pressing roller 11 is a free rolling structure, the continuous transmission of the dough sheet drives the pattern pressing roller 11 to rotate synchronously through friction. The spiral pattern preset on its surface is pressed into the pattern of the scallop on the surface of the dough sheet.

[0058] After the patterned sheet is pressed, it then reaches the bottom of the material feeding box 4. The opening and closing degree of the adjustable bottom plate 402 is adjusted according to the size of the auxiliary material particles in the box. At the same time, the drive motor of the material feeding roller 401 is started. The material feeding roller 401 is made of food-grade silicone material to avoid damaging some brittle auxiliary materials. The spiral groove on its surface can embed the auxiliary materials. The rotation driven by the motor makes the auxiliary materials evenly discharged from the bottom adjustable bottom plate 402 along the groove under the rotating structure and fall onto the surface of the sheet. The spiral structure, combined with the structure of the material feeding box 4, can prevent the auxiliary materials from leaking when not rotating.

[0059] The subsequent processes are the same as those for steamed bun production. The dough sheet containing auxiliary materials enters the tubular forming area 3 to form a tubular structure, and then is cut into flower roll blanks of the same size by the dough sheet roller cutting group 2. The blanks are transported to the subsequent stages by a small conveyor to complete the flower roll production.

[0060] When the equipment is used to produce steamed buns, the brush 503 of the special oiling component 5 for steamed buns and the pattern pressing roller 11 are both raised to a high position to avoid interference with the dough. The linear motor is started so that the moving table 8 drives the kneading and cutting circular blade 9 to move forward to the maximum operating range, located below the discharge end of the dough roller cutting group 2. The feeding panel of the filling conveying bin 10 is opened and the steamed bun filling is put into the bin. It is confirmed that the cylinder in the dough roller cutting group 2 drives the cutting blade to a high position to avoid cutting the tubular dough.

[0061] After the power is turned on, the pre-treatment of the dough sheet and the tubular forming process are the same as those for steamed bun production. While the dough sheet forms a tubular structure in the tubular forming area 3, the spiral conveying screw in the filling conveying chamber 10 rotates at a constant speed under the drive of the motor, pushing the filling in the chamber to the filling discharge guide pipe 1001, and continuously injecting it into the interior of the tubular dough sheet through the filling discharge guide pipe 1001, so as to achieve the covering of the filling and the dough sheet, forming a continuous filled tubular structure.

[0062] The filled tubular structure is then conveyed to the dough sheet roller cutting group 2. The two roller groups are positioned by adjusting the spacing to fit the two ends of the tubular structure. Since the cutting blade is in a high position, the tubular structure directly enters the center through hole of the kneading and cutting circular blade 9. The servo motor driving the drive gear 903 is equipped with an encoder. The encoder can collect the rotation angle signal of the motor rotor in real time and feed it back to the control system. Through the preset program of the control system, the servo motor drives the drive gear 903 to accurately achieve 180° reciprocating rotation.

[0063] When the drive gear 903 rotates, it drives the guide turntable 902, which meshes with it, to rotate synchronously. Since the limiting guide groove on the surface of the guide turntable 902 and the pin on the surface of the cutter form a sliding fit, when the guide turntable 902 rotates, the limiting guide groove applies a radial driving force to the cutter through the pin, so that the ring-shaped cutter moves synchronously opening and closing. When the cutter closes, its cutting edge can simultaneously complete the radial cutting and end face pinching of the filling tubular structure, forming a tightly sealed and uniformly sized bun blank. The blank is then discharged from the bottom through hole of the pinching and cutting circular cutter disc 9 into the small conveyor below to complete the bun making.

[0064] It should be noted that when the equipment is started for the first time, in addition to the tubular forming area 3 which requires manual assistance for initial edge rolling, the continuous dough sheets also need to be manually guided through each roller group in sequence, as well as pinched and cut circular cutter disc 9, to ensure that the dough sheets accurately enter the working area of ​​each component. At the same time, the cutters in this equipment are all made of food-grade UPE material, which has high non-stick properties and is not easy to damage the main conveyor table 1.

[0065] The present invention has been described by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
