Description

Technical Field

[0001] This invention relates to the field of machinery manufacturing technology for bowl-shaped foods such as non-fried noodles, rice noodles and vermicelli, and in particular to an airflow rotary disc and an airflow shaping machine. Background Technology

[0002] With the rapid growth in consumer demand for convenient and fast food products, more and more brands of such products, such as instant noodles, instant rice noodles, and instant hot and sour noodles, have emerged in the market, and consumers' requirements for product quality have also increased accordingly. Compared with fried instant noodles (which are shaped by frying), non-fried noodle cakes and products such as rice noodles and vermicelli are shaped by drying. The shaping process has become the current challenge in the noodle cake (vermicelli cake) process, as conventional shaping machines can no longer meet the requirements for shaping the flexible noodles and vermicelli into cake-like forms.

[0003] Non-fried noodles, rice noodles, and vermicelli are extruded, cooked, aged, and loosened until their moisture content is around 45%. At this stage, the noodles, rice noodles, and vermicelli have low moisture content, a certain degree of elasticity, and are easily resilient. During the bowl-packing process, some may be exposed or have uneven shape or thickness, resulting in irregular shapes after drying. Existing shaping machines, including airflow type, airflow-liquid flow mixing, and stirring types, cannot solve these problems for non-fried noodles, rice noodles, and vermicelli. Chinese invention patent CN219981958U discloses a noodle airflow shaping machine. This airflow shaping machine uses a flat plate design for its rotating air blowing device, which has chamfered edges. This flat plate and chamfered design results in noticeable protrusions around the edges of the noodle (vermicelli) cake, making it irregular. Furthermore, the large gap between the flat plate shaping device and the feeding device causes powder to overflow when pressed down. Summary of the Invention

[0004] To address the problems in the existing technology, the purpose of this invention is to provide an airflow rotating disc and an airflow shaping machine to improve the regularity of bowl-shaped dough or powder cakes, and to completely solve problems such as circumferential stripes and hedgehog-like shapes in some bowl-shaped foods.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] This invention provides an airflow rotating disk, including a rotating disk body. The upper center of the rotating disk body is provided with a central hole connected to a rotating shaft. The rotating disk body has a plurality of air blowing holes spaced apart from top to bottom and outward. The upper part of the air blowing holes communicates with the central hole through a connecting hole. The lower part of the air blowing holes extends to the bottom surface of the rotating disk body. The bottom surface of the rotating disk body is provided with a groove located inside the air blowing holes. The shape of the groove is adapted to the top shape of the bowl-shaped material to be formed.

[0007] The groove is hemispherical, spherical, or flat-bottomed bowl-shaped.

[0008] More preferably, the air inlet is tilted at a predetermined angle from top to bottom toward the tangent of the circle containing the top center of the air inlet.

[0009] More preferably, the preset angle is 15°.

[0010] More preferably, the rotating disk body has an air outlet that runs vertically through the center hole.

[0011] The present invention also provides an airflow shaping machine, including a frame and an airflow shaping device, wherein the frame is provided with a translation device for driving the airflow shaping device to move horizontally and a lifting device for driving the airflow shaping device to move up and down.

[0012] The airflow shaping device includes an airflow rotary disk, a shaping bracket, and multiple rotating shafts corresponding to the bowl rack positions, which are rotatably mounted on the shaping bracket. The upper end of each rotating shaft is connected to a high-pressure air pipe via a rotary joint. The airflow rotary disk is fixedly connected to the lower end of the rotating shaft. The shaping bracket is provided with a rotating component that drives the rotating shaft to rotate.

[0013] More preferably, the airflow rotary disk is made of plastic steel, the rotating shaft is made of aluminum alloy, and the airflow rotary disk is connected to the lower end of the rotating shaft through a reducing joint.

[0014] More preferably, the rotating assembly includes a drive motor, a drive gear, a driving gear, a transmission gear, and a transmission idler wheel. A transmission gear is fixedly connected to the outer wall of each rotating shaft. A transmission idler wheel is meshed between two adjacent transmission gears. The transmission idler wheel is rotatably connected to the shaping bracket. A driving gear is fixedly connected to at least one rotating shaft. The driving gear is meshed with the drive gear on the output shaft of the drive motor.

[0015] More preferably, the translational device includes a movable frame, a lead screw, and a lead screw motor. The airflow shaping device is mounted on the movable frame. The movable frame is slidably connected to the machine frame via a slider. The lead screw is fixedly connected to the machine frame. The lead screw motor is fixedly connected to the movable frame via a motor bracket. The lead screw motor is drivenly connected to the lead screw.

[0016] More preferably, the lifting device includes lifting components fixedly connected to both sides of the movable frame. The lifting components include a cylinder, a cylinder base plate, and two columns. The upper parts of the two columns are hoisted and connected to the movable frame at a distance, and the lower parts of the two columns are fixedly connected to both sides of the cylinder base plate at a distance. The bottom of the cylinder is fixedly connected to the middle of the cylinder base plate. A linear bearing is slidably connected to each column. The two sides of the shaping bracket are respectively fixedly connected to the top of the cylinder on the corresponding side and the two linear bearings. A compression spring is sleeved on the column between the linear bearing and the cylinder base plate. A buffer sleeve is sleeved on the column adjacent to the movable frame.

[0017] Compared with the prior art, the airflow rotating disk provided by the present invention has multiple air holes spaced apart on the circumference of the rotating disk body, inclined outward from top to bottom. During high-speed rotation, the airflow rotating disk guides the formation of a high-speed centripetal rotating airflow, rotating the hedgehog-like streaks on the circumference of the bowl-shaped material (powder cake, noodle cake) into the interior of the bowl-shaped material (powder cake, noodle cake). In addition, because the bottom surface of the rotating disk body has a groove located inside the air holes, and the shape of the groove is adapted to the top shape of the bowl-shaped material to be shaped, the bowl-shaped material (powder cake, noodle cake) can be shaped by the downward pressure of the airflow rotating disk during the descent, and it is not easy for hedgehog-like streaks to form on the circumference of the bowl-shaped material (powder cake, noodle cake). At the same time, in conjunction with the function of the air holes, it can improve the shaping regularity of the bowl-shaped material (powder cake, noodle cake) and effectively solve the problems of circumferential streaks and hedgehog-like streaks in the bowl-shaped material (powder cake). Meanwhile, the gap between the airflow rotating disc with a groove at the bottom and the material holding device can be set to be small, which can also prevent powder from overflowing when pressing down.

[0018] The airflow shaping machine provided by the present invention has the beneficial effects of the aforementioned airflow rotating disk, which will not be elaborated here. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] like Figures 1-6 As shown, a specific embodiment of the present invention provides an airflow rotating disk 201, including a rotating disk body 2011. A central hole 2012, connected to a rotating shaft 203, is provided at the upper center of the rotating disk body 2011. Multiple air-blowing holes 2013, inclined outwards from top to bottom, are spaced apart circumferentially inside the rotating disk body 2011. The angle of inclination depends on the specific shape of the bowl-shaped material (powder cake, noodle cake). Preferably, to achieve a more uniform blowing effect, the multiple air-blowing holes 2013 are evenly distributed circumferentially inside the rotating disk body 2011. The upper part of the air-blowing hole 2013 communicates with the central hole 2012 through a connecting hole 2014, and the lower part of the air-blowing hole 2013 extends to the bottom surface of the rotating disk body 2011. The connecting hole 2014 can be a horizontal process hole machined on the side wall of the rotating disk body, and a plug 2015 is connected to the opening of the process hole during use. The bottom surface of the rotating disc body 2011 is provided with a groove 2016 located inside the air hole 2013. The shape of the groove 2016 is adapted to the top shape of the bowl-shaped material to be formed.

[0037] In this embodiment, the airflow rotating disk 201 has multiple air holes 2013 spaced apart circumferentially inside the rotating disk body 2011, which are inclined outward from top to bottom. This allows for airflow during high-speed rotation of the airflow rotating disk 201. (See also...) Figures 3-6 The airflow is guided by the air hole 2013 to form a high-speed centripetal rotating airflow, which rotates the hedgehog-shaped ridges around the circumference of the bowl-shaped material (powder cake, noodle cake) into the bowl box 6.

[0038] Furthermore, since the bottom surface of the rotating disk body 2011 has a groove 2016 located inside the air blowing hole 2013, and the shape of the groove 2016 is adapted to the top shape of the bowl-shaped material to be formed, it can achieve the following during the descent of the airflow rotating disk 201: (See...) Figures 3-6 The airflow rotating disc presses down to shape the bowl-shaped material (powder cake, noodle cake), preventing the formation of spiky, hedgehog-like streaks around the circumference of the material. Simultaneously, the air inlet 2013 improves the regularity of the shaped material and effectively solves problems such as spiky streaks and spiky textures around the circumference of the bowl-shaped material (powder cake). Furthermore, the gap between the airflow rotating disc 201 with its bottom groove 2016 and the serving device (bowl) can be set to be small, preventing powder from overflowing during pressing.

[0039] In some embodiments, such as Figures 1-6 The groove 2016 is hemispherical, spherical, or flat-bottomed bowl-shaped. The shape of the groove 2016 is such that it gradually concaves upward from the side to the center, with a smooth transition, making it easier to shape the bowl-shaped material into the correct position.

[0040] In some embodiments, such as Figure 2 As shown, the air inlet 2013 is tilted at a preset angle from top to bottom towards the tangent of the circle containing the top center of the air inlet (the connection point between the air inlet 2013 and the connecting hole 2014). When the air inlet rotates with the rotating disk body, the tangent of the circle containing the top center of the air inlet rotates in both directions, but the air inlet 2013 tilts towards the tangent of the circle containing its top center, and tilts towards the direction of rotation. If it rotates clockwise, it tilts towards the clockwise direction of rotation. That is, the air inlet 2013 is set with a forward tilt angle from top to bottom towards the direction of rotation. In other words, the air inlet 2013 is first tilted relative to the axis of the central hole 2012, and then tilted at an angle from top to bottom towards the direction of rotation. In this way, the airflow blown out by the air outlet 2013 is not only inclined outward relative to the circumference of the dough (powder cake) in the bowl, but also inclined in the tangential direction of its circumference. During the high-speed rotation of the airflow rotating disk 201, the airflow blown out by the air outlet 2013 can have an upward lifting effect on the circumference of the dough (powder cake) in the bowl, similar to an inclined stirring rod having an upward pushing force on the stirred material while stirring it circumferentially, which is conducive to the shaping of the dough (powder cake) in the bowl.

[0041] Preferably, such as Figure 2 As shown, the air inlet 2013 is tilted at a preset angle of 15° from top to bottom in the direction of rotation of the rotating disk body 2011. At this angle, the forming effect of the cake (powder cake) inside the bowl is better.

[0042] Optionally, such as Figure 5 As shown, the rotating disc body 2011 has a vertically extending vent 2017 located near the central hole 2012. For some bowl-shaped products (powder compacts, noodle cakes), the vent 2017 is provided on the rotating disc body to improve the venting effect. Of course, in other bowl-shaped products (powder compacts, noodle cakes), since the bowl itself has a vent, it is not necessary to provide a vent on the rotating disc body 2011.

[0043] like Figures 1-14 As shown, a specific embodiment of the present invention provides an airflow shaping machine for shaping noodles, rice noodles, vermicelli, and noodle strips during the drying and bowl-packing process. The produced noodle and noodle cakes are neat in shape, without any streaks or fuzzy edges, and are easy to remove from the bowl. After use, the effect is significant, completely solving a major problem that has been difficult to solve for many years.

[0044] Specifically, the airflow shaping machine includes a frame 1 and an airflow shaping device 2. The frame 1 is equipped with a translation device 3 for driving the airflow shaping device 2 to move horizontally and a lifting device 4 for driving the airflow shaping device 2 to move vertically. The airflow shaping device 2 includes an airflow rotary disk 201, a shaping bracket 202, and multiple rotating shafts 203 corresponding to the positions of the bowls, which are rotatably mounted on the shaping bracket 202 via bearings. The rotating shafts 203 can be arranged in at least one row. The upper end of each rotating shaft 203 is connected to a high-pressure air pipe through a rotary joint 204. The rotary joint 204 is a high-speed rotary joint, which enables the rotating shaft 203 to rotate at high speed while the high-pressure air pipe does not rotate. The airflow rotary disk 201 is fixedly connected to the lower end of the rotating shaft 203, and the shaping bracket 202 is equipped with a rotating assembly 205 for driving the rotating shaft 203 to rotate.

[0045] The airflow shaping machine in this example includes the aforementioned airflow rotating disc 201, which has the beneficial effects of an airflow rotating disc, and will not be described in detail here. In addition, since this airflow shaping machine also includes a translation device 3 and a lifting device 4, the multiple airflow rotating discs 201 can easily approach the noodle bowl and move with the noodle bowl, facilitating the rotation and shaping of the moving noodle bowl.

[0046] In some embodiments, the airflow shaping machine further includes a controller and a signal device 5. The signal device 5 includes a sprocket 501, a signal disk 502, a first sensor 503, and a second sensor 504. The sprocket 501 is connected to the drying line chain drive and is rotatably connected to a bearing seat 506 via a sprocket shaft 505. The signal disk 502 is fixedly connected to the sprocket shaft 505. The first sensor 503 is disposed on the bearing seat 506 corresponding to the signal disk 502. When the rotation of the signal disk 502 triggers the first sensor 503, the controller controls the translation device 3 to start operating. The second sensor 504 is connected to the sprocket shaft 505, and the controller controls the translation device 3 to move precisely horizontally according to the signal from the second sensor 504. Specifically, the first sensor 503 is a U-shaped photoelectric switch sensor, and the second sensor 504 is a rotary photoelectric encoder. The signal device 5 also includes a protective cover 507 covering the sprocket 501, the signal disk 502, the first sensor 503, and the second sensor 504 to protect the signal device 5.

[0047] In this implementation, two sensors are set up. On the one hand, the first sensor 503 can sense the origin signal based on the rotation of the signal disk 502. On the other hand, the second sensor 504 can directly sense the precise and real-time rotation speed of the sprocket shaft 505 based on the sprocket shaft 505. This facilitates the synchronization of the translation device 3 with the chain movement of the drying line, thereby reducing the failure rate of the shaping equipment and improving accuracy.

[0048] In some embodiments, the airflow rotary disk 201 is made of plastic steel and the rotating shaft 203 is made of aluminum alloy. In order to avoid the airflow rotary disk 201 being easily damaged if it is directly connected to the rotating shaft 203, the airflow rotary disk is connected to the lower end of the rotating shaft 203 through a copper reducing joint 206, which can significantly improve the service life of the airflow rotary disk 201.

[0049] In some embodiments, such as Figure 8 and Figure 9 As shown, the rotating assembly 205 includes a drive motor 2051, a drive gear 2052, a driving gear 2053, a transmission gear 2054, and a transmission idler wheel 2055. A transmission gear 2054 is fixedly connected to the outer wall of each rotating shaft 203. A transmission idler wheel 2055 meshes between adjacent transmission gears 2054. The transmission idler wheel 2055 is rotatably connected to the shaping bracket 202 via bearings. Each side of the shaping bracket 202 has a rotating shaft with a driving gear 2053 fixedly connected to it. The driving gear 2053 meshes with the drive gear 2052 on the output shaft of the drive motor 2051. In this embodiment, gear transmission enables all transmission shafts to rotate synchronously in the same direction, resulting in high transmission accuracy and efficiency, low noise, and simple maintenance.

[0050] In some embodiments, such as Figure 12 and Figure 13 As shown, the translational device 3 includes a movable frame 301, a lead screw 302, and a lead screw motor 303. The airflow shaping device 2 is mounted on the movable frame 301, which is slidably connected to the machine frame 1 via a slider. The lead screw 302 is fixedly connected to the machine frame 1, and the lead screw motor 303 is fixedly connected to the movable frame 301 via a motor bracket 304. The lead screw motor 303 is driven by the lead screw 302. By setting the lead screw 302 and lead screw motor 303 in cooperation, the movable frame 301 can be easily moved in parallel by controlling the lead screw motor 303, and the movement accuracy is high.

[0051] Based on the above embodiments, such as Figure 14 As shown, the lifting device 4 includes lifting components fixedly connected to both sides of the movable frame 301. Each lifting component includes a cylinder 401, a cylinder base plate 402, and two columns 403. The upper parts of the two columns 403 are hoisted and connected to the movable frame 301 at intervals via hexagonal cap nuts 404. The lower parts of the two columns 403 are fixedly connected to both sides of the cylinder base plate 402 at intervals. The bottom of the cylinder is fixedly connected to the middle of the cylinder base plate 402. A linear bearing 405 is also slidably connected to each column 403. The two sides of the shaping bracket 202 are respectively fixedly connected to the top of the corresponding cylinder 401 and the two linear bearings 405. The extension and retraction of the cylinder 401 controls the raising and lowering of the shaping bracket 202, and the linear bearings 405 guide the raising and lowering of the shaping bracket 202.

[0052] In addition, a compression spring 406 is fitted onto the column 403 between the linear bearing 405 and the cylinder base plate 402, making the rising and falling process of the shaping bracket 202 smoother. A buffer sleeve 407 is fitted onto the column 403 adjacent to the movable frame 301, which can prevent the shaping bracket 202 from directly colliding with the movable frame 301 after rising, thus playing a buffering role.

[0053] The overall working principle of the airflow shaping machine in this application is as follows:

[0054] The operation of the drying line chain directly drives the sprocket 501 in the signal device 5 to rotate. The sprocket 501 triggers the photoelectric switch sensor (first sensor 503) through the sprocket shaft 505. The signal from the photoelectric switch sensor (first sensor 503) is transmitted to the controller to drive the lead screw motor 303 in the translation device 3 to start running. The rotary photoelectric encoder (second sensor 504) emits a high-frequency pulse signal, which can accurately control the running speed of the lead screw motor 303. The lead screw motor 303 converts the rotational motion into linear motion through the lead screw 302, so that the walking speed of the movable frame 301 and the walking speed of the drying line bowls are synchronized. After the movable frame 301 begins to move, the cylinder 401 of the lifting device 4 installed on the movable frame 301 operates, lowering the airflow shaping device 2 above the bowls. The airflow rotating disk 201 rotates and gradually approaches the noodle bowl 6. The controller controls the pneumatic solenoid valve connected to the high-pressure air pipe to operate, supplying compressed air into the airflow rotating disk 201 through the rotary joint 204. Through multiple air blowing holes 2013 on the airflow rotating disk 201, a high-speed rotating airflow is formed on the circumference of the bowl 6 filled with material. The high-speed rotating airflow quickly rotates the material not yet in the bowl 6 into the bowl 6. The airflow rotating disk 201 continues to descend, rotating and compressing the material. Under the action of the high-speed rotating airflow, the compressed and shaped noodle cake (powder cake) has no hedgehog-like streaks on its circumference. After the work is completed, the pneumatic solenoid valve stops supplying air, the cylinder of the lifting device 4 rises, the screw motor 303 rotates in reverse, and the movable frame 301 quickly returns to the starting position to wait for the next signal, and so on in a cycle.
