Description

Technical Field

[0001] This utility model mainly relates to the technical field of steamed bun processing equipment, specifically a steamed bun machine equipped with a dough pressing device. Background Technology

[0002] Steamed bun processing equipment is a general term for specialized machinery that covers the entire process or some key steps of steamed bun production. Its core function is to complete a series of operations from dough processing and filling preparation to the final initial processing of steamed buns through mechanization, automation or semi-automation.

[0003] The steamed bun machine is a core piece of equipment in the steamed bun processing system. It integrates core functions such as dough processing, dough sheet forming, automatic filling, and steamed bun shaping. It is the core machinery that realizes the transformation of steamed buns from raw materials to finished products. Compared with scattered single-process equipment, a small steamed bun machine can quickly complete the production of raw steamed bun embryos through integrated design. It is mainly aimed at small breakfast shops, community breakfast shops, and individual catering operators. The twin-screw feeding device inside the steamed bun machine is only designed for conveying and cannot replace the core role of the dough press machine. The dough press machine is a key piece of equipment to ensure the quality and continuity of steamed bun processing. Its core function is to stretch the fermented dough into a regular sheet with a complete structure and orderly arrangement of gluten fibers by repeatedly rolling the dough. At the same time, it removes excess air bubbles from the dough, so that the steamed bun skin has good elasticity and fluffy texture, and avoids problems such as holes and collapse after steaming. However, existing small steamed bun machines have obvious limitations in the dough sheet processing stage. Whether the dough press machine is used alone to complete the dough pressing... After the dough is formed into regular sheets, it is still produced by using a special small press machine. However, it cannot be directly connected to the steamed bun machine. The pressed dough sheets still need to be manually transferred to the steamed bun machine's feed inlet. This not only results in long process intervals and cumbersome manual operation, but also may affect hygiene and production continuity due to the exposure and falling of the dough sheets during the transfer process. Furthermore, the dough is prone to sticking during repeated pressing to form sheets, which still requires manual sprinkling of flour to solve the problem, further increasing the cumbersomeness of manual operation. Uneven sprinkling of flour may also affect the quality of the dough sheets, ultimately having an adverse impact on the shaping effect and taste of the steamed buns. Utility Model Content

[0004] This utility model addresses the problem of overly simplistic solutions in existing technologies by providing a steamed bun machine equipped with a dough pressing device. This solves the problem mentioned in the background section that existing small steamed bun machines, whether using a dough pressing device alone or in conjunction with a dedicated small pressing machine, cannot directly connect to the steamed bun machine. The pressed dough sheets still require manual transfer to the machine's feed inlet, leading to long processing times, cumbersome manual operation, and potential hygiene and production continuity issues due to dough exposure and falling during transfer. Furthermore, the dough sheets are prone to sticking during repeated pressing, requiring manual application of flour to resolve this, further increasing the complexity of manual operation.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A steamed bun machine equipped with a dough pressing device includes a steamed bun machine and a dough pressing machine. A discharge conveyor is located below the dough pressing machine. One end of the discharge conveyor is mounted and rotatably connected to the lower part of the forming cutter disc inside the steamed bun machine. A dough sheet receiving conveyor and a feeding guide conveyor are rotatably connected inside the dough pressing machine. The feeding guide conveyor is located above the dough sheet receiving conveyor. A dough sheet pressing mechanism is located on one side of the feeding guide conveyor. A cylinder is mounted on one end of the dough pressing machine adjacent to the dough sheet pressing mechanism. A feeding rack is located inside the dough pressing machine, above the feeding guide conveyor. An eccentric wheel is rotatably connected to one side of the feeding rack.

[0006] Furthermore, the dough press is fixed to the mounting surface by a frame and adjacent to one side of the steamed bun machine. A guide plate is fixed to the inner wall of the dough press on the side near the dough receiving conveyor. The guide plate has a "C"-shaped cut at the end that is in contact with the dough receiving conveyor. The guide plate includes an inclined plate at an angle of 30°-45° to the horizontal plane and a vertical short plate perpendicular to the bottom of the inclined plate. The vertical short plate of the guide plate extends to the feed port of the steamed bun machine for the dough forming station.

[0007] Furthermore, the feeding guide conveyor is inclined at an angle of 15°-30° to the horizontal plane, and the sheet pressing mechanism is rotatably connected to one side of the lower end of the feeding guide conveyor, while the feeding rack is located on one side of the higher end of the feeding guide conveyor.

[0008] Furthermore, the dough sheet pressing mechanism includes an active pressure roller, a driven pressure roller, a stopper and a movable support. A stepper motor for driving the active pressure roller to rotate is provided on one side of the outer wall of the dough press. The movable support is slidably connected to the corresponding grooves opened on both sides of the inner wall of the dough press.

[0009] Furthermore, an integral strip plate is provided between the movable supports, the power output end of the cylinder is fixedly connected to the strip plate, the two ends of the baffle are fixedly connected to the corresponding sides of the movable supports, and an arc-shaped groove is provided at the bottom of the baffle. The curvature of the arc-shaped groove is adapted to the curvature of the outer peripheral surface of the driven pressure roller, and the inner wall of the arc-shaped groove is fitted to the outer peripheral surface of the driven pressure roller.

[0010] Furthermore, the diameter of the driven pressure roller is larger than that of the driving pressure roller, and there is a small gap between the bottom of the driven pressure roller and the surface of the dough receiving conveyor. The length of the dough receiving conveyor is twice the length of the feeding guide conveyor. Side fixed-width roller groups are provided at both ends of the inner wall of the dough press corresponding to the dough receiving conveyor and the feeding guide conveyor.

[0011] Furthermore, the top of the dough press machine has a through-hole dough feeding slot at the position corresponding to the dough sheet pressing mechanism, and a flour feeding door plate is rotatably connected to the corresponding feeding rack via a damping hinge. The bottom of the feeding rack is a metal mesh grid plate, and sliders are provided on both sides of the feeding rack. The sliders slide in cooperation with the limiting grooves on the inner wall of the dough press machine. Springs are connected to the sliders, and the other end of the springs is fixed to the groove cavity wall of the dough press machine.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Through the structural design of the dough press machine and the steamed bun machine being fixed adjacent to each other and precisely connected by the guide plate, the dough pressing process and the steamed bun forming process are integrated. After the dough sheet receiving conveyor in the dough press machine completes the dough sheet pressing, it can directly switch the transmission direction and accurately guide the pressed dough sheet into the feed port of the dough sheet forming station of the steamed bun machine through the guide plate. This completely eliminates the need for manual dough pressing and manual transfer of dough sheets. At the same time, the diffuse reflection photoelectric sensor can accurately detect the status of the dough sheet pressing station and ensure that the dough sheet pressing count is met before switching the conveying direction. This avoids efficiency loss caused by process intervals and prevents production rhythm from being affected by manual transfer operation errors.

[0013] 2. The movable support is driven by a cylinder to slide within the chute, allowing precise adjustment of the gap between the active and driven pressure rollers. This allows for both increasing the gap to reduce pressing intensity for harder or thicker dough sheets and decreasing the gap to enhance the pressing effect for softer or thinner dough sheets. Its adaptability far exceeds that of existing small steamed bun machines with external dough pressing equipment. The inclined setting of the feeding guide conveyor table, combined with the side fixed-width roller group, can apply lateral limiting throughout the dough sheet conveying process, preventing the dough sheet from shifting and deforming, and ensuring that the dough sheet enters the gap between the pressure rollers with a uniform width. At the same time, the feeding frame achieves left and right reciprocating motion under the action of the eccentric wheel and spring, and evenly sprinkles powder through the bottom metal mesh plate, effectively solving the problems of easy sticking and irregular dough sheet size during pressing in existing small steamed bun machines.

[0014] 3. By integrating the dough pressing and forming processes and the automatic powdering design, the ease of operation and production stability of the equipment can be greatly improved. At the same time, it frees up manpower time for operators of small breakfast shops and other scenarios, allowing them to take care of other business affairs.

[0020] Please refer to the appendix carefully. Figure 1-3A steamed bun machine equipped with a dough pressing device includes a steamed bun machine 1 and a dough pressing machine 3. A discharge conveyor 2 is provided below the dough pressing machine 3. One end of the discharge conveyor 2 is installed and rotatably connected to the lower part of the forming cutter disc inside the steamed bun machine 1. A dough receiving conveyor 4 and a feeding guide conveyor 5 are rotatably connected inside the dough pressing machine 3. The feeding guide conveyor 5 is located above the dough receiving conveyor 4. A dough pressing mechanism 6 is provided on one side of the feeding guide conveyor 5. A cylinder 7 is installed on one end of the dough pressing machine 3 adjacent to the dough pressing mechanism 6. A feeding rack 9 is provided inside the dough pressing machine 3. The feeding rack 9 is located above the feeding guide conveyor 5. An eccentric wheel 10 is rotatably connected to one side of the feeding rack 9.

[0021] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the dough press 3 is fixed to the mounting surface by the frame and is adjacent to one side of the steamed bun machine 1. The inner wall of the dough press 3 is fixed with a guide plate 11 on the side near the dough receiving conveyor table 4. The guide plate 11 has a "C" shaped cut at the end that is in contact with the dough receiving conveyor table 4. The guide plate 11 includes an inclined plate with an angle of 30°-45° to the horizontal plane and a vertical short plate perpendicular to the bottom of the inclined plate. The vertical short plate of the guide plate 11 extends to the feed port of the steamed bun machine 1 for the dough forming station.

[0022] With the above structure, the dough press 3 is fixed to the frame and adjacent to the bun machine 1. With the help of the guide plate 11, the dough press and the bun machine 1 are connected. This integrates the pre-pressing function into the small bun machine 1, which greatly reduces the tediousness of manually pressing the dough separately and then manually transferring the dough sheet to the bun machine 1. It allows the pressed dough sheet to be directly fed into the machine through the guide plate 11, avoiding process intervals and improving the overall process efficiency of bun production.

[0023] In this embodiment, as Figure 2 and Figure 3 As shown, the feeding guide conveyor 5 is inclined at an angle of 15°-30° to the horizontal plane, and the sheet pressing mechanism 6 is rotatably connected to the lower end of the feeding guide conveyor 5, while the feeding rack 9 is located on the higher end of the feeding guide conveyor 5.

[0024] With the above structure, the inclined setting of the feeding guide conveyor 5 and the rotatable connection of the sheet pressing mechanism 6 to the lower end of the conveyor table allow the sheet to accurately align with the gap between the two rollers, shorten the sheet transfer path, and improve the overall connection efficiency of sheet conveying and pressing.

[0025] In this embodiment, as Figure 2 and Figure 3As shown, the dough pressing mechanism 6 includes an active pressure roller 601, a driven pressure roller 602, a stopper 603, and a movable support 604. A stepper motor for driving the active pressure roller 601 to rotate is provided on one side of the outer wall of the dough press 3. The movable support 604 is slidably connected to the corresponding grooves opened on both sides of the inner wall of the dough press 3.

[0026] With the above structure, the movable support 604 is slidably connected to the inner wall groove of the dough press 3, which can provide a stable moving track for the driven pressure roller 602, and can also cooperate with the cylinder 7 to realize the adjustment of the gap between the two rollers to meet the processing requirements of different dough sheet thicknesses.

[0027] In this embodiment, as Figure 2 and Figure 3 As shown, an integral strip plate is provided between the movable supports 604. The power output end of the cylinder 7 is fixedly connected to the strip plate. The two ends of the baffle 603 are fixedly connected to the corresponding sides of the movable supports 604. An arc-shaped groove is provided at the bottom of the baffle 603. The curvature of the arc-shaped groove is adapted to the curvature of the outer peripheral surface of the driven pressure roller 602, and the inner wall of the arc-shaped groove is fitted to the outer peripheral surface of the driven pressure roller 602.

[0028] Through the above structure, the integrated strip plate between the movable supports 604 allows the power of the cylinder 7 to be evenly transmitted to the movable supports 604 on both sides through the plate, so as to achieve the purpose of uniform adjustment of the gap between the active pressure roller 601 and the driven pressure roller 602 along the entire length, thereby improving the flexibility of the equipment to process sheets with different characteristics. The arc-shaped groove at the bottom of the baffle 603 not only avoids friction with the driven pressure roller 602 and prevents it from interfering with its rotation, but also effectively prevents the sheet from overflowing from the other side, ensuring the continuous and stable transmission of the sheet during the pressing process.

[0029] In this embodiment, as Figure 2 and Figure 3 As shown, the diameter of the driven pressure roller 602 is larger than the diameter of the driven pressure roller 601, and there is a small gap between the bottom of the driven pressure roller 602 and the surface of the dough receiving conveyor 4. The length of the dough receiving conveyor 4 is twice the length of the feeding guide conveyor 5. Side fixed width roller groups 8 are provided at both ends of the inner wall of the dough press machine 3 above the dough receiving conveyor 4 and the feeding guide conveyor 5.

[0030] Through the above structure, the large diameter of the driven pressure roller 602 increases the contact area with the dough sheet. Combined with the power transmission of the active pressure roller 601, it can more fully crush the dough sheet entering the gap. On the other hand, it does not require an additional power mechanism and can achieve stable passive rotation by relying solely on the friction between the dough sheet and the active pressure roller 601. At the same time, the small gap between its bottom and the surface of the dough sheet receiving conveyor table 4 can not only avoid wear between the roller and the table, but also guide the transmission path of the dough sheet. The side fixed width roller group 8 can apply lateral limit to the dough sheet throughout the conveying process, accurately regulate the width of the dough sheet, prevent the dough sheet from shifting, deforming or uneven in width, and ensure that the dough sheet always enters the gap between the active pressure roller 601 and the driven pressure roller 602 with a uniform width. This not only improves the dimensional consistency of the dough sheet after pressing, but also lays the foundation for the subsequent accurate introduction into the steamed bun machine 1 for the dough sheet forming station.

[0031] In this embodiment, as Figure 3 As shown, the top of the dough press 3 has a dough feeding slot through the corresponding dough pressing mechanism 6. A flour feeding door is rotatably connected to the corresponding feeding rack 9 via a damping hinge. The bottom of the feeding rack 9 is a metal mesh grid plate, and sliders are provided on both sides of the feeding rack 9. The sliders slide in cooperation with the limiting grooves on the inner wall of the dough press 3. Springs are connected to the sliders, and the other end of the springs is fixed to the groove cavity wall of the dough press 3.

[0032] With the above structure, the two slots at the top of the dough press machine 3 have a clear division of labor, which improves the convenience of feeding dough and flour, reduces the exposed space of the outer wall of the equipment, effectively reduces the risk of external impurities entering, and improves the hygiene and safety of food processing. The additional feeding rack 9 and eccentric wheel 10 structure, with the help of the bottom metal mesh plate, the sliders on both sides and the spring, the feeding rack 9 realizes the left and right reciprocating motion under the drive of the eccentric wheel 10, so that the flour falls evenly and adheres to the surface of the dough sheet, which not only ensures the uniformity of the anti-stick effect, but also avoids the tedious operation of manually sprinkling flour.

[0033] The specific operating procedure of this utility model is as follows: The steamed bun machine 1 adopts the BY22-TX87T model. Its general principle is that the processed dough sheet is put into the double spiral feeding device, and the dough sheet is evenly extruded from the annular mold at the end of the device to form a hollow tubular continuous dough with a smooth inner wall and uniform thickness. At the same time, the filling is injected into the hollow tubular continuous dough through an independent quantitative filling conveying system. Finally, the continuous tubular dough filled with filling is conveyed to the forming cutter disc at the end of the equipment. During the rotation process, the tubular dough is cut and shaped at equal intervals to form a steamed bun product with complete pleats and uniform shape. Finally, the discharge conveyor 2 conveys it to the next process. It should be noted that the dough sheet receiving conveyor 4 and the feeding guide conveyor 5 are equipped with a special tension adjustment mechanism. One set of driven rollers of each is installed on a sliding slider base. When it is necessary to adjust the tension of the corresponding conveyor belt, the horizontal movement of the slider base can be achieved by means of a screw adjustment device. This is a common tension adjustment structure in the existing technology. The specific details are not described here.

[0034] When using this steamed bun machine equipped with a dough pressing device, the user can put the fermented dough into the feeding slot at the top of the dough press machine 3 corresponding to the dough pressing mechanism 6. After turning on the power, the active pressing roller 601 rotates counterclockwise under the drive of the stepper motor on one side. The feeding guide conveyor 5 is in the same direction as the active pressing roller 601 and runs, thereby conveying the dough from the lower end to the higher end and causing the dough to fall from the higher end onto the dough receiving conveyor 4.

[0035] The conveying direction of the dough receiving conveyor 4 is opposite to that of the feeding guide conveyor 5, which can transport the dough back to the dough pressing mechanism 6 from below. Since the size of the active pressure roller 601 is smaller than that of the driven pressure roller 602, when the dough is conveyed to the active pressure roller 601 on the surface of the dough receiving conveyor 4, the dough will enter the gap between the active pressure roller 601 and the driven pressure roller 602 under the action of the actively rotating active pressure roller 601 and the conveying force of the dough itself. The driven pressure roller 602 will be passively rotated by the friction between the dough and the active pressure roller 601. The two rollers form a relative crushing force, which gradually squeezes and stretches the originally loose dough. After the dough is subjected to uniform compression in the gap between the two rollers, the internal gluten fibers are stretched and arranged in an orderly manner. Excess air bubbles are gradually discharged during the crushing process, and finally a dough sheet with uniform thickness and tight texture is formed, completing the transformation from dough to dough sheet.

[0036] Meanwhile, the baffle 603 at the top of the driven pressure roller 602 has an arc-shaped groove at its bottom that fits against the outer circumferential surface of the driven pressure roller 602, which can effectively prevent the sheet from overflowing from the top during the pressing process and ensure the stability of the sheet pressing.

[0037] When the dough sheet is reciprocated on the surfaces of the dough sheet receiving conveyor 4 and the feeding guide conveyor 5, the side width-fixing roller group 8 is provided on both surfaces, which can exert a lateral limiting and regularizing effect on the dough sheet during the conveying process. This effectively avoids the dough sheet from shifting, deforming or uneven in width, and ensures that the dough sheet always enters the gap between the active pressure roller 601 and the driven pressure roller 602 with a uniform width to complete the pressing. This lays the foundation for the uniform forming of the dough sheet and its precise introduction into the steamed bun machine 1.

[0038] Meanwhile, the pressing force and dough sheet forming specifications can be flexibly adjusted according to the type of dough (such as high-gluten dough, low-gluten dough), water content, and required dough sheet thickness. The operator can adjust the gap between the driven pressure roller 602 and the driving pressure roller 601 by controlling the cylinder 7. The extension and retraction of the power output end of the cylinder 7 drives the movable support 604 to slide in the groove on the inner wall of the dough press 3, thereby realizing the adjustment of the position of the driven pressure roller 602. For harder dough or dough requiring thicker sheets, the gap is increased to reduce the pressing intensity; for softer dough or dough requiring thinner sheets, the gap is decreased to enhance the rolling effect, so as to achieve the ideal pressing effect.

[0039] During the repeated pressing of the dough sheet, the flour feeding door plate corresponding to the feeding rack 9 on the top of the dough press 3 can be opened to feed flour into the feeding rack 9. After starting the drive motor corresponding to the external eccentric wheel 10, the eccentric wheel 10 starts to rotate, and its eccentric surface will periodically contact the feeding rack 9.

[0040] Because the sliders on both sides of the feeding rack 9 slide in conjunction with the limiting grooves on the inner wall of the dough press 3, and the other end of the spring connected to the slider is fixed to the groove cavity wall of the dough press 3, the feeding rack 9 will reciprocate left and right under the combined action of the force of the eccentric wheel 10 and the elastic force of the spring. This movement causes the flour on the metal grid plate at the bottom of the feeding rack 9 to fall evenly and contact the surface of the dough sheet, which has an anti-sticking effect and also allows the flour to adhere more evenly to the dough sheet.

[0041] Because a diffuse reflection photoelectric sensor is installed on the inner wall of the dough sheet receiving conveyor 4 near the active pressure roller 601, the sensor can detect in real time whether the dough sheet has reached the pressing station. Each time the dough sheet passes by, it sends a signal back to the equipment control system. The system accumulates the number of pressings based on this. When the accumulated number reaches the set value, the sensor sends a signal to trigger the control system, which switches the dough sheet receiving conveyor 4 from forward transmission to pressing mechanism to reverse transmission to steamed bun machine 1, thus completing the pressing process of the dough sheet. This ensures that the number of pressings is accurate and avoids uneven dough sheet texture due to insufficient pressing or damage to the dough sheet gluten due to over-pressing.

[0042] The present invention has been described above 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.
