Description

Technical Field

[0001] The invention relates to the technical field of dough rolling machines, and in particular to a dough rolling machine for steamed buns and dumpling skins. Background Art

[0002] In the field of food processing, steamed buns and dumplings are traditional and popular pasta. The dough rolling process in their production process has a crucial impact on production efficiency and dough quality. With the large-scale development of the food industry, the traditional manual dough rolling method can no longer meet the growing market demand. Dough rolling machines have emerged and have been widely used.

[0003] However, there is a prominent problem in the dough rolling machine in the prior art, that is, after the dough rolling operation is completed, the dough skin often sticks to the mold. This sticking phenomenon makes it difficult to remove the dough skin from the mold. In the actual production process, in order to remove the sticky dough skin, it is often necessary to consume extra manpower and time, which seriously affects the production efficiency. Moreover, when forcibly removing the sticky dough skin, it is very easy to cause the dough skin to be damaged or incomplete in shape, which not only reduces the quality of the finished dough skin, but also increases the loss of raw materials and increases the production cost. Summary of the invention

[0004] The invention provides a bun and dumpling wrapper rolling machine, which solves the problem in the related art that the wrapper may be adhered to a mold after the wrapper is rolled, and is difficult to be removed.

[0005] The technical solution of the present invention is as follows: A bun and dumpling wrapper rolling machine, comprising: frame; A dough rolling device, wherein the dough rolling device is arranged on the frame; A mounting plate, the mounting plate being vertically slidably disposed on the frame; A dough rolling mold, the dough rolling mold is flipped and arranged on the mounting plate, and the dough rolling mold comprises: An outer mold, the outer mold is flipped and arranged on the mounting plate, the outer mold has a cavity inside, and the cavity has a first abutting surface and a second abutting surface; an inner mold, the inner mold being slidably disposed in the cavity; One end of the inner mold close to the dough rolling device is located in the cavity, forming a dough rolling space with the outer mold, and the other end of the inner mold extends out of the cavity. After the mounting plate slides, the dough rolling space approaches or moves away from the dough rolling device; The inner mold has a contact portion. After the dough is rolled, the dough becomes a dough skin. After the dough rolling mold is turned over, the inner mold slides along the cavity, so that the contact portion contacts and strikes the first abutting surface or the second abutting surface, so as to provide force for the dough skin to leave the dough rolling space.

[0006] Optionally, it also includes: A material receiving rack is located below the dough rolling mould, and the material receiving rack has a material receiving platform, and the dough skin falls into the material receiving platform after leaving the dough rolling space.

[0007] Optionally, both ends of the outer mold have slide grooves, and further include: A sliding rod, wherein the sliding rod is slidably arranged in the sliding groove, and one end of the sliding rod extends out of the sliding groove. After the outer mold slides, the sliding rod contacts the dough rolling device or the material support frame, so that the sliding rod slides into the sliding groove, and the sliding rod has a spiral convex track; A rotation blocking rod, wherein the rotation blocking rod is an arc-shaped rod, one end of which is rotatably arranged on a side wall of one side of the cavity and abuts against the spiral convex track. After the sliding rod slides, the rotation blocking rod is driven to rotate, so that the rotation blocking rod contacts or cancels the contact with the dough skin, and is used to prevent the dough skin from leaving the dough skin rolling space in advance when the dough skin rolling mold is turned over; A first elastic member, wherein the first elastic member is arranged in the slide slot, and both ends of the first elastic member act on the sliding rod and the slide slot to provide a force for the other end of the sliding rod to extend out of the slide slot.

[0008] Optionally, the material receiving frame has a plurality of material receiving platforms, and after the material receiving frame rotates, the plurality of material receiving platforms move sequentially to below the dough rolling space, further comprising: There are several brush plates, one end of each brush plate is arranged on the material receiving frame and is located at the intersection of adjacent material receiving platforms. After the material receiving frame rotates, the other ends of several brush plates slide and abut against the inner mold and the outer mold in sequence close to one end of the material receiving frame to clean the rolling space.

[0009] Optionally, the brush plate is slidably arranged on the material support frame, and further comprises: A second elastic member, wherein the second elastic member is arranged on the material support frame, and two ends of the second elastic member respectively act on the material support frame and the brush plate to provide a force to move the brush plate away from the material support frame.

[0010] Optionally, it also includes: A flour box is arranged on the frame and below the material receiving frame. After the material receiving frame rotates, a plurality of brush plates pass through the flour box in sequence, and the material receiving frame rotates continuously, so that the flour adheres to the dough rolling space.

[0011] Optionally, the material support rack has a plurality of push rod portions, and the push rod portions are used to contact and abut against the sliding rod.

[0012] Optionally, it also includes: A rotating shaft, the rotating shaft is rotatably arranged on the frame, and the rotating shaft has an eccentric portion; A connecting rod, one end of which is hinged on the eccentric part, and the other end of which is hinged on the mounting plate. After the rotating shaft rotates, the mounting plate is driven to slide vertically on the frame.

[0013] Optionally, it also includes: A connecting shaft, the connecting shaft is rotatably arranged on the mounting plate, the dough rolling mold is arranged at one end of the connecting shaft, and the other end of the connecting shaft passes through the mounting plate and is located at the other side of the mounting plate; A ratchet pawl, the ratchet pawl being swingably disposed on the connecting shaft; A gear, the gear is rotatably sleeved on the connecting shaft, the inner wall of the gear has a ratchet ring, and the ratchet ring cooperates with the ratchet pawl to abut against the ratchet; The frame has teeth, and the gear is engaged with the teeth. After the mounting plate slides close to the dough rolling device, the gear rotates without driving the connecting shaft to rotate. After the mounting plate moves away from the dough rolling device, the gear drives the connecting shaft to rotate, so that the dough rolling mold is flipped.

[0014] Optionally, the connecting shaft has a mounting portion, and the gear is rotatably arranged on the mounting portion.

[0015] The working principle and beneficial effects of the present invention are: In the present invention, the outer mold is flipped and set on one side of the mounting plate. The shape of the inner cavity of the outer mold is designed according to the shape of the desired bun or dumpling skin. The first abutting surface and the second abutting surface are set at relative positions inside the cavity and have smooth surfaces. The inner mold is slidably set in the cavity through a slider structure that matches the shape of the cavity. The inner mold is located in the cavity in an initial state near one end of the rolling device, forming a rolling space with the outer mold, and the other end extends out of the cavity for subsequent operations. When the dough is placed in the rolling space, the mounting plate slides upward so that the rolling space is close to the rolling device, and the rolling device rolls the dough. After the rolling is completed, the rolling mold is flipped, and the inner mold slides along the cavity due to gravity, so that the abutting portion abuts and knocks against the first abutting surface or the second abutting surface, thereby causing the dough to leave the rolling space.

[0016] The advantage is that the inner mold and the outer mold form an adjustable rolling space, which can meet the needs of rolling dough of different thicknesses. In addition, the knocking effect of the abutment of the inner mold and the inner abutment surface of the outer mold effectively solves the problem of the dough sticking to the mold and being difficult to remove, improves production efficiency and the quality of the finished dough, and reduces the situation of dough damage or incomplete shape caused by adhesion.

[0022] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] Reference Figure 1 to Figure 10 , which is the first embodiment of the present invention, a bun and dumpling wrapper rolling machine is proposed, comprising a frame 1; a wrapper rolling device 2 is arranged on the frame 1; a mounting plate 3 is vertically slidably arranged on the frame 1; a wrapper rolling mold 4 is flipped and arranged on the mounting plate 3, and the wrapper rolling mold 4 comprises: an outer mold 5 is flipped and arranged on the mounting plate 3, and the outer mold 5 has a cavity 6 inside, and the cavity 6 has a first abutting surface 7 and a second abutting surface 8; an inner mold 9 is slidably arranged in the cavity 6; the inner mold 9 is located in the cavity 6 at one end close to the wrapper rolling device 2, and forms a wrapper rolling space 10 with the outer mold 5, and the other end of the inner mold 9 extends out of the cavity 6, after the mounting plate 3 slides, the wrapper rolling space 10 approaches or moves away from the wrapper rolling device 2; the inner mold 9 has an abutting portion 11, after the wrapper rolling is completed, the dough becomes a dough skin, after the wrapper rolling mold 4 is flipped, the inner mold 9 slides along the cavity 6, so that the abutting portion 11 abuts and knocks with the first abutting surface 7 or the second abutting surface 8, which is used to provide a force for the dough skin to escape from the wrapper rolling space 10.

[0024] In this embodiment, in order to solve the problem in the related art that the dough may stick to the mold after the dough is rolled and is difficult to remove, a dough rolling machine for buns and dumplings is designed. First, a frame 1 is constructed to provide a support frame for the entire device. The dough rolling device 2 is installed at a suitable position on the top of the frame 1, for example, fixed by bolts, so that it can stably roll and press the dough placed below it. The mounting plate 3 is vertically slidably connected to the frame 1 through a slide rail, and the slide rail can adopt a high-precision linear guide rail to ensure that the mounting plate 3 slides up and down smoothly and with high precision.

[0025] The outer mold 5 is turned over and set on one side of the mounting plate 3. The shape of the inner cavity 6 of the outer mold 5 is designed according to the shape of the required bun or dumpling wrapper. The first abutting surface 7 and the second abutting surface 8 are set at relative positions inside the cavity 6 and have smooth surfaces. The inner mold 9 is slidably set in the cavity 6 through a slider structure matching the shape of the cavity 6. The inner mold 9 is located in the cavity 6 at one end close to the rolling device 2 in the initial state, forming a rolling space 10 with the outer mold 5, and the other end extends out of the cavity 6 for subsequent operations. When the dough is placed in the rolling space 10, the mounting plate 3 slides upward so that the rolling space 10 is close to the rolling device 2, and the rolling device 2 rolls the dough. After the rolling is completed, the rolling mold 4 is turned over, and the inner mold 9 slides along the cavity 6 due to gravity, so that the abutment portion 11 abuts and knocks with the first abutment surface 7 or the second abutment surface 8, so that the dough is separated from the rolling space 10.

[0026] The advantage is that the inner mold 9 and the outer mold 5 form an adjustable rolling space 10, which can meet the rolling requirements of dough skins of different thicknesses. In addition, the knocking effect of the abutting portion 11 of the inner mold 9 and the inner abutting surface of the outer mold 5 effectively solves the problem of the dough skin sticking to the mold and being difficult to remove, improves the production efficiency and the quality of the finished dough skin, and reduces the situation of the dough skin being damaged or incomplete in shape due to adhesion.

[0027] Furthermore, it also includes a material receiving rack 12, which is located below the dough rolling mold 4. The material receiving rack 12 has a material receiving platform 13, and the dough skin falls into the material receiving platform 13 after leaving the dough rolling space 10.

[0028] In this embodiment, a material receiving frame 12 is installed below the dough rolling mold 4, and a material receiving platform 13 of the material receiving frame 12 is made of food-grade plastic material. The material receiving frame 12 is arranged at the lower position of the frame 1 to ensure its stable position. When the dough is rolled in the dough rolling mold 4, and after the dough rolling mold 4 is turned over, the dough is separated from the dough rolling space 10 under the action of sliding and knocking of the abutment 11, and directly falls onto the material receiving platform 13, so as to be collected later or to perform the next processing operation.

[0029] The advantage is that the setting of the material receiving rack 12 provides an area specifically for collecting dough, so that the dough can be transferred from the dough rolling mold 4 to the material receiving platform 13 in an orderly manner, avoiding the dough from being scattered randomly, facilitating subsequent sorting and processing, and improving the operating convenience of the entire dough rolling machine and the continuity of the production process.

[0030] Furthermore, both ends of the outer mold 5 have a slide groove 14, and also include a sliding rod 15, which is slidably set in the slide groove 14, and one end of the sliding rod 15 extends out of the slide groove 14. After the outer mold 5 slides, the sliding rod 15 touches the rolling device 2 or the material support frame 12, so that the sliding rod 15 slides into the slide groove 14, and the sliding rod 15 has a spiral convex rail 16; the rotation blocking rod 17 is an arc rod, and one end of the rotation blocking rod 17 is rotatably set on a side wall of one side of the cavity 6, and abuts against the spiral convex rail 16. After the sliding rod 15 slides, it drives the rotation blocking rod 17 to rotate, so that the rotation blocking rod 17 contacts or cancels the release of the dough, which is used to prevent the dough from leaving the rolling space 10 in advance when the rolling mold 4 is turned over; the first elastic member 18 is set in the slide groove 14, and its two ends act on the sliding rod 15 and the slide groove 14, which is used to provide a force for the other end of the sliding rod 15 to extend out of the slide groove 14.

[0031] In this embodiment, a chute 14 is processed at both ends of the outer mold 5, and a sliding rod 15 is installed in the chute 14. A clearance fit is adopted between the sliding rod 15 and the chute 14 to ensure smooth sliding without excessive shaking. One end of the sliding rod 15 extends out of the chute 14, and a spiral convex track 16 is processed on the sliding rod 15. The rotation blocking rod 17 is an arc rod, one end of which is rotatably arranged on a side wall of the cavity 6 through the sliding rod 15, and abuts against the spiral convex track 16. The first elastic member 18 is a spring, which is placed in the chute 14, one end of which abuts against the bottom of the chute 14, and the other end abuts against one end of the sliding rod 15 located in the chute 14, providing a force for the other end of the sliding rod 15 to extend out of the chute 14. When the outer mold 5 is in the process of turning over, when the sliding rod 15 touches the rolling device 2 or the material support frame 12, it will slide into the chute 14, driving the rotation blocking rod 17 to rotate, thereby changing the contact state between the rotation blocking rod 17 and the dough, and preventing the dough from leaving the rolling space 10 in advance.

[0032] The advantage is that, through the coordinated action of the sliding rod 15, the rotating blocking rod 17 and the first elastic member 18, the timing of the dough skin's detachment can be accurately controlled when the dough rolling mold 4 is flipped, thereby avoiding deformation or damage of the dough skin due to premature detachment, further improving the dough skin production quality and the stability of the production process, and reducing the scrap rate.

[0033] Furthermore, the material receiving rack 12 has a plurality of material receiving platforms 13. After the material receiving rack 12 rotates, the plurality of material receiving platforms 13 move in sequence to the bottom of the rolling space 10. The material receiving rack 12 also includes a brush plate 19. There are a plurality of brush plates 19. One end of the brush plate 19 is arranged on the material receiving rack 12 at the intersection of adjacent material receiving platforms 13. After the material receiving rack 12 rotates, the other ends of the plurality of brush plates 19 slide and abut against the inner mold 9 and the outer mold 5 close to one end of the material receiving rack 12 in sequence for cleaning the rolling space 10.

[0034] In this embodiment, the material receiving frame 12 is designed with a plurality of material receiving platforms 13, which are distributed in an annular shape on the material receiving frame 12. The material receiving frame 12 is rotatably connected to the frame 1 through a central axis, and can be driven by a motor or rotated manually. The number of brush plates 19 is the same as the number of material receiving platforms 13, one end of which is fixed on the material receiving frame 12, located at the intersection of adjacent material receiving platforms 13, and the bristles of the brush plates 19 are facing the rolling mold 4. When the material receiving frame 12 rotates, the other end of the brush plate 19 slides and abuts against the inner mold 9 and the outer mold 5 close to one end of the material receiving frame 12 in turn, cleaning the flour or dough debris remaining in the rolling space 10.

[0035] The advantage is that the design of multiple material receiving platforms 13 improves the collection capacity and efficiency of dough. The brush plate 19 can automatically clean the dough rolling space 10 during the rotation of the material receiving frame 12, keep the dough rolling mold 4 clean, avoid residual substances affecting the quality of the next dough rolling, and ensure the consistency and hygiene of dough production.

[0036] Furthermore, the brush plate 19 is slidably disposed on the material support frame 12 and also includes a second elastic member 20 . The second elastic member 20 is disposed on the material support frame 12 , and its two ends respectively act on the material support frame 12 and the brush plate 19 to provide a force to move the brush plate 19 away from the material support frame 12 .

[0037] In this embodiment, the brush plate 19 is slidably arranged on the material support frame 12 through a slide groove. The second elastic member 20 is a tension spring, one end of which is fixed on the material support frame 12 and the other end is connected to the brush plate 19, providing a force to keep the brush plate 19 away from the material support frame 12. In this way, when the brush plate 19 abuts against the inner mold 9 and the outer mold 5, the contact pressure between the bristles and the mold can be adaptively adjusted according to the shape and surface condition of the mold, so as to better clean the dough rolling space 10.

[0038] The advantage is that the sliding setting of the brush plate 19 and the cooperation of the second elastic member 20 enable the brush plate 19 to more flexibly adapt to different mold states during the cleaning process, thereby ensuring the cleaning effect while reducing the wear on the mold and extending the service life of the dough rolling mold 4.

[0039] Furthermore, it also includes a flour box 21, which is arranged on the frame 1 and located below the material receiving frame 12. After the material receiving frame 12 rotates, a plurality of brush plates 19 pass through the flour box 21 in sequence, and the material receiving frame 12 continues to rotate, so that the flour adheres to the rolling space 10.

[0040] In this embodiment, the flour box 21 is installed on the frame 1 and is located below the material receiving frame 12. The flour box 21 can adopt a drawer-type structure to facilitate adding and cleaning flour. When the material receiving frame 12 rotates, a plurality of brush plates 19 pass through the flour box 21 in sequence. The brush plates 19 will dip a certain amount of flour when passing through the flour box 21. As the material receiving frame 12 continues to rotate, the flour is brought to the dough rolling space 10, which plays a role in preventing adhesion and lubricating the dough.

[0041] The advantage is that the setting of the flour box 21 realizes the automatic supply of flour and its uniform distribution in the rolling space 10, effectively preventing the dough from sticking during the rolling process, improving the production quality and appearance smoothness of the dough, reducing the operation steps of manual powder sprinkling, and improving production efficiency and operational convenience.

[0042] Furthermore, the material support frame 12 has a plurality of push rod portions 22 , and the push rod portions 22 are used to contact and abut against the sliding rod 15 .

[0043] In this embodiment, a plurality of push rods 22 are arranged on the material support frame 12, and their positions and shapes are designed according to the motion trajectory of the sliding rod 15. When the material support frame 12 rotates, the push rods 22 can contact and abut the sliding rod 15, pushing the sliding rod 15 to slide in the slide groove 14, thereby triggering the rotation of the rotation blocking rod 17 to control whether the dough skin falls off from the rolling space 10.

[0044] The advantage is that the setting of the push rod part 22 provides a reliable trigger mechanism for the movement of the sliding rod 15, making the linkage between the material receiving frame 12 and the rolling mold 4 more precise and stable, ensuring that the dough leaves the rolling space 10 at the right time, and improving the automation level and operational reliability of the entire equipment.

[0045] Furthermore, it also includes a rotating shaft 23, which is rotatably set on the frame 1, and the rotating shaft 23 has an eccentric portion 24; one end of the connecting rod 25 is hingedly set on the eccentric portion 24, and the other end is hingedly set on the mounting plate 3. After the rotating shaft 23 rotates, it drives the mounting plate 3 to slide vertically on the frame 1.

[0046] In this embodiment, a rotating shaft 23 is installed on the frame 1, and the rotating shaft 23 is rotatably connected to the frame 1 through a bearing to ensure flexible rotation. The eccentric portion 24 of the rotating shaft 23 is hinged to one end of the connecting rod 25, and the other end of the connecting rod 25 is hinged to the mounting plate 3. The rotating shaft 23 is driven to rotate by a motor or other power source, and the eccentric portion 24 drives the connecting rod 25 to move, so that the mounting plate 3 slides vertically on the frame 1, so as to adjust the distance between the rolling space 10 and the rolling device 2.

[0047] The advantage is that the structure of the rotating shaft 23 and the connecting rod 25 is used to drive the mounting plate 3 to slide vertically. The structure is simple and the transmission efficiency is high. The lifting and lowering position of the mounting plate 3 can be accurately controlled, and then the relative position of the rolling space 10 and the rolling device 2 can be adjusted to meet the rolling requirements of dough of different thicknesses, thereby improving the versatility and flexibility of the equipment.

[0048] Furthermore, it also includes a connecting shaft 26, which is rotatably set on the mounting plate 3, the dough rolling mold 4 is set at one end of the connecting shaft 26, and the other end of the connecting shaft 26 passes through the mounting plate 3 and is located on the other side of the mounting plate 3; the pawl 27 is swingably set on the connecting shaft 26; the gear 28 is rotatably sleeved on the connecting shaft 26, and the inner wall of the gear 28 has a ratchet ring 29, and the ratchet ring 29 cooperates and abuts with the pawl 27; the frame 1 has teeth 30, and the gear 28 is meshed with the teeth 30. After the mounting plate 3 slides close to the dough rolling device 2, the gear 28 rotates without driving the connecting shaft 26 to rotate. After the mounting plate 3 is away from the dough rolling device 2, the gear 28 drives the connecting shaft 26 to rotate, so that the dough rolling mold 4 is flipped.

[0049] In this embodiment, when the mounting plate 3 slides close to the dough rolling device 2, the gear 28 engages with the teeth 30. Due to the one-way locking effect of the pawl 27, the gear 28 rotates but does not drive the connecting shaft 26 to rotate; when the mounting plate 3 moves away from the dough rolling device 2, the gear 28 drives the connecting shaft 26 to rotate, causing the dough rolling mold 4 to flip.

[0050] The advantage is that the matching structure of the connecting shaft 26, the ratchet 27, the gear 28 and the teeth 30 of the frame 1 realizes the precise linkage control between the sliding of the mounting plate 3 and the flipping of the dough rolling mold 4, realizes the corresponding function conversion in different operation stages, improves the automation degree of the equipment and the accuracy of operation, reduces manual intervention, and improves production efficiency and product quality stability.

[0051] Furthermore, the connecting shaft 26 has a mounting portion 31 , and the gear 28 is rotatably disposed on the mounting portion 31 .

[0052] In this embodiment, the mounting portion 31 of the connecting shaft 26 adopts a stepped shaft structure, and the gear 28 is mounted on the middle shaft section of the mounting portion 31 through a bearing, ensuring that the gear 28 can rotate stably and is fixed in relative position with the connecting shaft 26. In this way, during the operation of the entire device, the matching relationship between the gear 28 and the connecting shaft 26 is stable and reliable, ensuring the linkage control accuracy of the sliding of the mounting plate 3 and the flipping of the dough rolling mold 4.

[0053] The advantage is that the reasonable design of the mounting portion 31 of the connecting shaft 26 provides a stable foundation for the installation of the gear 28, improves the reliability and durability of the entire transmission structure, reduces equipment failures and precision degradation caused by unstable component installation, and ensures the long-term stable operation performance of the bun and dumpling skin rolling machine.
