Description

Technical Field

[0001] This utility model belongs to the technical field of food machinery, specifically relating to a high-efficiency downward pressing rolling machine. Background Technology

[0002] Existing machinery for processing dough for buns, pancakes, and dumplings typically involves rolling out a large sheet of dough, then using specialized tools to cut it into specific shapes and sizes suitable for wrapping dumplings, buns, or pies. The leftover scraps are then kneaded back into the dough, and the process is repeated. This process inevitably results in scraps, leading to repeated kneading and inefficient processing, and also raises concerns about hygiene and safety due to the potential for contamination from impurities.

[0003] In view of this, the inventor has devoted himself to research and has specially developed and designed a high-efficiency, downward-pressing dough rolling machine, which can avoid repeated kneading of the dough, thereby preventing the mixing of impurities, making the processing more hygienic and safer, and improving production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency pressing and rolling machine, which has a simple structure and is hygienic, safe and efficient in operation.

[0005] To achieve the above objectives, the solution of this utility model is as follows: A high-efficiency rolling dough assembly includes a lifting component, a rolling dough assembly, an upper rolling die, and a lower rolling die assembly. The lifting component is mounted on a frame, and the rolling dough assembly is mounted on the lifting component. The rolling dough assembly includes a rolling dough motor and a rotating rod. The upper rolling die includes a rolling roller, a roller frame, a separating membrane, and a roller cover. The roller frame is mounted on the rotating rod, the rolling roller is mounted on the roller frame, and the roller cover is installed below the motor mount of the rolling dough motor, covering the roller frame and the rolling roller. A separating membrane is placed below the rolling roller and fixed below the roller cover. The lower rolling die assembly includes a lower die base and a dough tray. The lower mold base is movably mounted on the frame, and a set of dough trays for dough preparation are formed on the lower mold base. The positioning component is located between the frame and the lower mold base. When the lower mold base moves on the frame, it is positioned by the positioning component so that one of the dough trays is directly opposite the rolling roller and the roller cover. The gap between the dough tray, the roller cover, and the separating film forms the dough rolling space. The rolling component is driven by the lifting component to move up and down. The rolling motor drives the rolling roller to rotate through the rotating rod and the roller frame. The rolling roller rolls through the separating film to roll the dough in the dough tray, thus rolling the dough.

[0006] The lower mold base is mounted on the machine frame via a rotating shaft. The lower mold base rotates relative to the machine frame around the rotating shaft, and a set of agent grooves are evenly distributed on the lower mold base around the rotating shaft. The rotating shaft of the lower mold base is connected to a rotary motor, and the rotary motor drives the rotating shaft to make the lower mold base rotate.

[0007] The lower mold base is mounted on the frame via a conveyor belt. The lower mold base moves horizontally relative to the frame, driven by the conveyor belt. A set of agent tanks are evenly distributed on the lower mold base. The conveyor belt of the lower mold base is connected to a conveyor motor, which drives the conveyor belt to move the lower mold base horizontally.

[0008] The set of dough trays can be two, three, four or more.

[0009] The positioning component consists of a positioning sensor and a set of positioners. The positioning sensor is mounted on the frame, and the set of positioners is mounted on the lower mold base one by one, corresponding to the positions of a set of agent tanks. Positioning is achieved by restricting the movement of the lower mold base through the cooperation of the positioners and the positioning sensor.

[0010] The lower end of the roller cover is equipped with a retaining ring, which is used to fix the isolation film to the bottom of the roller cover.

[0011] The rolling roller consists of a central shaft roller and two left and right roller sleeves. The central shaft roller is mounted on a roller frame, and the two left and right roller sleeves are fitted onto the central shaft roller. During rolling, the two left and right roller sleeves rotate in opposite directions.

[0012] The rolling roller has a shape that is thin at the center of rotation and gradually thickens at the periphery.

[0013] The dough tray has a shape that is low in the middle and gradually rises around the edges.

[0014] The rolling assembly is mounted on the lifting assembly via a buffer assembly; a hanging hole is provided on the motor base of the rolling motor; the buffer assembly has a base plate, a hanging rod, and a return spring. The base plate is mounted on the lifting assembly and is driven by the lifting assembly to move the base plate up and down. The upper end of the hanging rod passes through the hanging hole of the motor base and the return spring and is then fixed on the base plate. The two ends of the return spring abut against the base plate and the motor base. The lower end of the hanging rod forms a stop to prevent the motor base from falling off.

[0015] The buffer assembly's base plate and the rolling motor's motor mount are also equipped with mutually cooperating sensors. The control unit controls whether the rolling assembly starts or not by receiving information from the sensors.

[0016] The frame is equipped with circular guide posts and square guide rails. The motor base of the rolling mill motor has corresponding guide holes, guide blocks, and the rolling mill motor. The guide holes cooperate with the circular guide posts, and the guide blocks cooperate with the square guide rails to guide the motor base of the rolling mill motor to move smoothly on the frame.

[0017] A displacement sensor is installed on the rolling assembly, and an upper limit switch and a lower limit switch are installed on the frame corresponding to the movement trajectory of the rolling assembly. The displacement sensor, in conjunction with the upper limit switch and the lower limit switch, limits the vertical movement of the rolling assembly.

[0018] The lifting assembly consists of a lifting motor, a coupling, a lead screw, and a nut. The lifting motor is fixedly mounted on the frame, and the lead screw is mounted on the frame. The output end of the lifting motor is connected to one end of the lead screw via the coupling. The nut is fitted onto the lead screw, and the lifting motor drives the lead screw through the coupling to move the nut up and down. The rolling assembly is mounted on the nut. The lifting assembly can also be a pneumatic lifting device, an electric lifting device, or other devices capable of lifting.

[0019] The motor base of the rolling mill motor is indirectly mounted on the nut of the lifting assembly through a buffer assembly. The motor base of the rolling mill motor has a hanging hole. The buffer assembly has a base plate, a hanging rod and a return spring. The base plate is mounted on the nut of the lifting assembly and the lifting assembly drives the base plate to move up and down. The upper end of the hanging rod passes through the hanging hole of the motor base and the return spring and is then fixed on the base plate. The two ends of the return spring abut against the base plate and the motor base. The lower end of the hanging rod forms a stop to prevent the motor base from falling off.

[0020] After adopting the above solution, the present invention has a simple, compact structure and small size. When this invention is used for rolling dough, the dough portion is first placed in a dough portion groove away from the roller cover. Then, this dough portion groove containing the dough portion is moved to face the rolling roller and roller cover and positioned by the positioning component. Then, the lifting component and the rolling component are activated. The lifting component drives the rolling component to move downward, causing the rolling roller, roller cover, and separating film to descend until they land on the dough portion. The dough portion is confined in the dough rolling space formed by the dough portion groove, roller cover, and separating film. The rolling component drives the rolling roller to rotate, causing the rolling roller to roll the dough portion through the separating film. After rolling, the lifting component drives the rolling component to move upward, causing the rolling roller, roller cover, and separating film to rise and leave the dough portion groove, thus completing the rolling of one dough portion. Finally, the dough portion groove with the rolled dough portion is moved away from the roller cover, and the rolled dough portion can then be removed. Furthermore, another dough ball is placed in a different dough ball slot away from the outer cover of the roller beforehand. As the lower mold moves, this other dough ball slot is moved to the bottom of the outer cover of the roller, ready to roll out the next dough sheet.

[0021] This invention automates the dough rolling process, allowing each dough portion to be directly rolled into the desired size of dough sheet, resulting in more hygienic production. Utilizing a set of dough trays (two or more), this invention allows one dough portion to be placed into another tray while another dough sheet is being rolled, shortening the dough placement time and increasing operational efficiency. Furthermore, fingers can avoid the rolling area when placing dough portions and retrieving dough sheets, making the operation safer. By changing the rolling roller of the upper rolling die and the dough tray of the lower rolling die, this invention can be adapted to different sizes of dough portions, producing dough sheets of various sizes.

[0022] In this invention, the outer cover of the roller serves two purposes: firstly, to fix the isolation film, and secondly, to prevent fingers from touching the rolling roller. Furthermore, the outer cover, together with the dough tray and the isolation film, can position the size of the dough model. The isolation film can stabilize the dough pieces to prevent them from shifting, and also ensure that the rolling roller rolls the dough evenly.

[0023] This invention, by selecting suitable rolling rollers and dough troughs—for example, a rolling roller with a shape that is thinner at the center and gradually thicker at the edges, or a dough trough with a shape that is lower in the middle and gradually higher at the edges—can produce dough sheets that are similar to hand-rolled dough, with a thicker center and thinner edges. When these dough sheets are used to wrap dumplings, buns, and pies, the bottom of the dumpling, bun, or pie will not be too thin, and there will be no dough accumulation or excessive thickness at the sealing point. The resulting dumplings, buns, and pies will have a good texture and an attractive appearance. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1 to 11As shown, this utility model discloses a high-efficiency downward pressing dough rolling machine, including a lifting assembly 10, a dough rolling assembly 20, an upper dough rolling mold 30, and a lower dough rolling mold assembly 40, as well as conventional equipment components such as a control unit 70, which will not be described here. The lifting assembly 10 is mounted on the frame 60, and the dough rolling assembly 20 is mounted on the lifting assembly 10. The dough rolling assembly 20 is driven by the lifting assembly 10 to perform lifting and lowering movements. The dough rolling assembly 20 has a dough rolling motor 21 and a rotating rod 22, with the dough rolling motor 21 driving the rotating rod 22 to perform rotational movements. The rolling die 30 has a rolling roller 31, a roller frame 32, a separating film 33, and a roller cover 34. The roller frame 32 is mounted on a rotating rod 22, and the rolling roller 31 is mounted on the roller frame 32. The roller cover 34 is mounted below the motor base 23 of the rolling motor 21 and covers the outside of the roller frame 32 and the rolling roller 31. The rotating rod 22 drives the roller frame 32 to rotate, so that the rolling roller 31 rotates together with the roller frame 32. The separating film 33 is set below the rolling roller 31 and is fixed below the roller cover 34. The dough rolling die assembly 40 has a dough filling slot 41, a lower die base 42, and a positioning component 43. The lower die base 42 is movably mounted on the frame 60. A set of dough filling slots 41 are formed on the lower die base 42 for filling the dough. The positioning component 43 is disposed between the frame 60 and the lower die base 42. When the lower die base 42 moves on the frame 60, it is positioned by means of the positioning component 43, so that one of the dough filling slots 41 is directly opposite the rolling roller 31 and the roller cover 34. The gap between the dough filling slot 41, the roller cover 34, and the separating film 33 forms a dough rolling space.

[0028] When this invention is used for rolling dough, the dough portion is first placed in a dough portion trough 41 away from the roller cover 34. Then, by moving the lower mold base 42, the dough portion trough 41 is moved to face the rolling roller 31 and roller cover 34 and is positioned by the positioning component 43. Then, the lifting component 10 and the rolling component 20 are activated. The lifting component 10 drives the rolling component 20 to descend, causing the rolling roller 31, roller cover 34 and separating film 33 to descend until they land on the dough portion in the dough portion trough 41. The dough portion is then confined within the dough portion trough 41, the roller cover 34 and the separating film 33 for rolling. In the space, the rolling motor 21 of the rolling assembly 20 drives the rolling roller 31 to rotate via the rotating rod 22 and the roller frame 32. The rolling roller 31 rolls the dough in the dough tray 41 with the separating film 33 in between. After rolling, the lifting assembly 10 drives the rolling assembly 20 to rise, causing the rolling roller 31, the roller cover 34, and the separating film 33 to rise and leave the dough tray 41. At this point, the rolling of one dough sheet is completed. Finally, by moving the lower mold base 42, the dough tray 41 with the rolled dough sheet is moved away from the roller cover 34, and the rolled dough sheet can then be removed. This utility model realizes automated dough rolling operation and is safe to operate. The roller cover 34 serves two purposes: firstly, it secures the isolation film 33; secondly, it provides safety protection to prevent fingers from touching the rolling roller 31; and thirdly, the roller cover 34, together with the dough tray 41 and the isolation film 33, can position the dough mold to the correct size. The isolation film 33 stabilizes the dough pieces in the dough tray 41, preventing them from shifting, and ensures that the rolling roller 31 rolls the dough pieces evenly. This invention achieves automated dough rolling, allowing each dough piece to be directly rolled into the desired size of dough sheet, resulting in more hygienic production. By changing the rolling roller 31 of the upper rolling mold 30 and the dough tray 41 of the lower rolling mold assembly 40, this invention can be adapted to different sizes of dough pieces to produce dough sheets of different specifications.

[0029] Furthermore, in this invention, while rolling out the previous dough sheet, another dough ball can be placed in a different dough ball groove 41 away from the roller cover 34 beforehand. After the previous dough sheet is rolled out, as the lower mold base 42 moves, this other dough ball groove 41 can be moved back below the roller cover 34, ready to roll out the next dough sheet. Thus, this invention utilizes a set of dough ball grooves 41, and the number of dough ball grooves 41 in this set can be two (e.g., ...). Figure 1 ), three (such as Figure 10 ), four (such as Figure 11 (or more) can be used to place another dough portion into another dough portion slot 41 while one dough sheet is being rolled out, shortening the dough portion placement time and achieving high efficiency. Moreover, fingers can avoid the rolling station when placing dough portions and picking up dough sheets, making the operation safer.

[0030] The movable installation method of the lower mold base 42 on the frame 60 of this utility model can be rotational movement, horizontal movement, or other movement methods. As shown in the figure, the lower mold base 42 is mounted on the frame 60 via a rotating shaft 44. The lower mold base 42 rotates relative to the frame 60 with the rotating shaft 44 as the center. A set of agent grooves 41 are evenly distributed on the lower mold base 42 around the rotating shaft 44. The rotating shaft 44 of the lower mold base 42 is connected to a rotary motor 45 via a transmission belt 46 (or a transmission gear set, etc.), and the rotary motor 45 drives the rotating shaft 44 to rotate the lower mold base 42. Alternatively, horizontal movement can be used. The lower mold base 42 can be mounted on the frame 60 via a conveyor belt. The lower mold base 42 is driven by the conveyor belt to move horizontally relative to the frame 60, and a set of agent grooves 41 are evenly distributed on the lower mold base 42. The conveyor belt of the lower mold base 42 is connected to a conveyor motor, and the conveyor motor drives the conveyor belt to move the lower mold base 42 horizontally.

[0031] The positioning component 43 of the rolling mill lower mold assembly 40 of this utility model can be specifically as shown in the figure, but is not limited to the structure shown in the figure. It consists of a positioning sensor 431 and a set of positioners 432. The positioning sensor 431 is installed on the frame 60. The set of positioners 432 are installed on the lower mold base 42 one by one, corresponding to the positions of a set of dough trays 41. By cooperating with the positioning sensor 431, the positioner 432 controls whether the rotary motor 45 works and restricts the movement of the lower mold base 42, thereby achieving positioning and positioning the corresponding dough trays 41 below the rolling mill roller 31 and the roller cover 34.

[0032] A further optimized design of this invention is that the lower end of the roller cover 34 is equipped with a retaining ring 35. The retaining ring 35 secures the release liner 33 to the bottom of the roller cover 34, and the release liner 33 can be replaced by removing the retaining ring 35. Furthermore, with the addition of the retaining ring 35, the diameter of the dough sheet can be limited by the engagement of the retaining ring 35 with the dough paste groove 41. Changing the retaining ring 35 and the dough paste groove 41 allows for alteration of the produced dough sheet size.

[0033] A further optimized design of this utility model is that the rolling roller 31 consists of a central shaft roller 311 and two left and right roller sleeves 312. The central shaft roller 311 is mounted on the roller frame 32, and the two left and right roller sleeves 312 are fitted onto the central shaft roller 311. During rolling, the two left and right roller sleeves 312 rotate in opposite directions. Of course, the central shaft roller 311 of the rolling roller 31 can also be only half of the one shown in the figure, and the central shaft roller 311 can only have one roller sleeve 312, but the rolling efficiency will be relatively reduced.

[0034] A further optimized design of this invention is that the rolling roller 31 is thinner at the center of rotation and gradually thickens towards the periphery, or the dough trough 41 is lower in the middle and gradually rises towards the periphery. In this way, the rolled dough resembles hand-rolled dough, exhibiting a thicker center and thinner periphery. When the resulting dough is used to wrap dumplings, buns, and pies, the bottom of the dumpling, bun, or pie will not be too thin, and there will be no dough accumulation or excessive thickness at the sealing point. The resulting dumplings, buns, and pies will have a good texture and an attractive appearance.

[0035] In a preferred design of this invention, the lifting assembly 10 comprises a lifting motor 11, a coupling 12, a lead screw 13, and a nut 14. The lifting motor 11 is fixedly mounted on the frame 60, and the lead screw 13 is mounted on the frame 60. The output end of the lifting motor 11 is connected to one end of the lead screw 13 via the coupling 12. The nut 14 is fitted onto the lead screw 13. The lifting motor 11 drives the lead screw 13 through the coupling 12 to move the nut 14 up and down. The rolling assembly 20 is directly or indirectly mounted on the nut 14, enabling the lifting assembly 10 to drive the rolling assembly 20 to move up and down. The lifting assembly 10 of this invention can also be a pneumatic lifting device, an electric lifting device, or other devices capable of lifting functions, which will not be elaborated here.

[0036] In order to enable the equipment to adapt to rolling dough pieces of different heights and to make the rolling process gentler, the present invention further indirectly mounts the rolling assembly 20 on the lifting assembly 10 through the buffer assembly 50. In the specific embodiment shown in the figure, the motor base 23 of the rolling motor 21 is indirectly mounted on the nut 14 of the lifting assembly 10 through the buffer assembly 50. A hanging hole 24 is made on the motor base 23 of the rolling motor 21; the buffer assembly 50 has a base plate 51, a hanging rod 52, and a return spring 53. The number of hanging rods 52 and return springs 53 is determined by design and is not limited by the illustration. The base plate 51 is installed on the nut 14 of the lifting assembly 10. The lead screw 13 of the lifting assembly 10 and the nut 14 cooperate to drive the base plate 51 to move up and down. The upper end of the hanging rod 52 passes through the hanging hole 24 of the motor base 23 and the return spring 53 and is then fixed to the base plate 51. The two ends of the return spring 53 abut against the base plate 51 and the motor base 23. The lower end of the hanging rod 52 forms a stop 54 to prevent the motor base 23 from falling off. The hanging rod 52 can be a long bolt. During the rolling process, the lifting assembly 10 drives the rolling assembly 20 to descend through the buffer assembly 50 to perform the rolling operation. During the rolling process, for dough pieces of different heights, the motor base 23 of the rolling assembly 20 adaptively adjusts its height under the elastic action of the return spring 53. Under the action of the return spring 53, the rolling roller 31 and the separating film 33 always act on the dough pieces, achieving rolling of dough pieces of different heights. Furthermore, this invention also installs cooperating sensors 55 and 27 on the base plate 51 of the buffer assembly 50 and the motor base 23 of the rolling motor 21. The control unit 70 controls whether the rolling assembly 20 starts or stops by receiving information about the interaction between sensors 55 and 27. In this embodiment, when sensors 55 and 27 are in contact, the rolling assembly 20 starts rolling; when sensors 55 and 27 are not in contact, the rolling assembly 20 stops rolling. Of course, whether the rolling assembly 20 starts or stops can also be set by the control unit 70.

[0037] To ensure the smooth up-and-down movement of the rolling assembly 20, this invention further provides a circular guide post 611 and a square guide rail 612 on the frame 60. The motor base 23 of the rolling motor 21 has a corresponding guide hole 251, a guide block 252, and is equipped with the rolling motor 21. The guide hole 251 cooperates with the circular guide post 611, and the guide block 252 cooperates with the square guide rail 612 to guide the motor base 23 of the rolling motor 21 to move smoothly on the frame 60, ensuring that the rolling down is always in one direction and avoiding rolling deviation that could cause the dough to become deformed.

[0038] To control the start and stop of the rolling action, this invention also installs a displacement sensor 26 on the rolling assembly 20. An upper limit switch 62 and a lower limit switch 63 are installed on the frame 60 corresponding to the movement trajectory of the rolling assembly 20. The displacement sensor 26, in conjunction with the upper and lower limit switches 62 and 63, limits the vertical movement of the rolling assembly 20. When the rolling assembly 20 is driven upwards by the lifting assembly 10, and the displacement sensor 26 senses the upper limit switch 62, the entire device stops working. At this point, the dough rolling is complete, the rolling roller 31 and the separating film 33 rise away from the dough tray 41, and the dough tray 41 is moved away from the rolling position, allowing the rolled dough to be removed. After the dough portion is placed in the dough portion 41 and moved to the rolling position, the lifting assembly 10 and the rolling assembly 20 are activated. The rolling assembly 20 is driven downwards by the lifting assembly 10. After the displacement sensor 26 detects the lower limit switch 63, the lifting assembly 10 stops working, and the rolling assembly 20 performs the rolling operation until the rolling is completed. This design of the present invention can control the thickness of the rolled dough, and the vertical travel of the rolling assembly 20 can also be set by the control unit 70.

[0039] The above are merely specific embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any structural designs that are the same as or similar to the above embodiments of this utility model, or any substitutions, modifications, or equivalent changes made on the essence and scope of this utility model, shall fall within the protection scope of this application.
