Compared with fried instant noodles (shaped by frying), non-fried noodles and rice noodles, vermicelli and other products that are shaped by drying, the shaping process has become the current difficulty in the noodle (powder) process. Conventional shaping machines can no longer meet the requirements for the shaping of flexible noodles and vermicelli.

[0003] After non-fried noodles, rice noodles and vermicelli are squeezed, aged and loosened, the moisture content is kept at about 45%, and the noodles, rice noodles and vermicelli are put into bowls and shaped and enter the drying machine. At this time, the noodles, rice noodles and vermicelli have low moisture, certain flexibility and are easy to rebound. During the bowling process, there may be partial exposure or uneven shape and thickness, which leads to irregular shape of the noodles or powder cakes after drying. Existing shaping machines are divided into air flow type and air flow liquid flow mixing and stirring forms, which can not solve such problems of non-fried noodles, rice noodles and vermicelli. Chinese invention patent CN219981958U discloses a noodle air flow shaping machine, the rotary blowing device of the air flow shaping machine is designed in the form of a flat plate, and is provided with chamfers at the same time.

[0035] The technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] like Figure 1-Figure 6 As shown, a specific embodiment of the present invention provides an airflow rotating disk 201 including a rotating disk body 2011, and a center hole 2012 connected to the rotating shaft 203 is provided in the middle of the upper end of the rotating disk body 2011. A plurality of blowing holes 2013 inclined outward from top to bottom are spaced apart in the circumferential interior of the rotating disk body 2011, and the angle of inclination is determined according to the specific shape of the bowl material (powder cake, noodle cake). Preferably, in order to make the blowing effect more uniform, a plurality of blowing holes 2013 are evenly distributed in the circumferential interior of the rotating disk body 2011. The upper part of the blowing hole 2013 is connected to the center hole 2012 through a connecting hole 2014, and the lower part of the blowing hole 2013 extends to the bottom surface of the rotating disk body 2011. Among them, the connecting hole 2014 can be a horizontal process hole processed on the side wall of the rotating disk body, and the orifice of the process hole is connected with a plug 2015 when in use. The bottom surface of the rotating disk body 2011 is provided with a groove 2016 located inside the blowing hole 2013, and the shape of the groove 2016 is adapted to the top shape of the bowl-filled material to be formed.

[0037] In this embodiment, the airflow rotating disk 201 is provided with a plurality of blowing holes 2013 which are spaced apart in the circumferential direction of the rotating disk body 2011 and are inclined outward from top to bottom. Figure 3-Figure 6 , a high-speed centripetal rotating airflow is formed through the air blowing hole 2013, and the hedgehog-like strips around the bowl material (powder cake, noodle cake) are rotated into the bowl box 6.

[0038] In addition, since the bottom surface of the rotating disk body 2011 is provided with a groove 2016 located inside the blowing hole 2013, and the shape of the groove 2016 is adapted to the top shape of the bowl-filled material to be formed, the rotating disk 2011 can be moved downward during the descent of the airflow rotating disk 2011. Figure 3-Figure 6 The bowl-filled material (powder cake, dough cake) is shaped by pressing down the airflow rotating disk, and it is not easy to form hedgehog-like strips on the circumference of the bowl-filled material (powder cake, dough cake). At the same time, the blowing hole 2013 can improve the shaping regularity of the bowl-filled material (powder cake, dough cake), and can well solve the problems of strips and hedgehog-like strips on the circumference of the dough bowl-filled cake (powder cake). At the same time, the gap between the airflow rotating disk 201 with a groove 2016 at the bottom and the material holding device (bowl box) can be set to be smaller, and powder and flour can be prevented from overflowing when pressing down.

[0039] In some embodiments, Figure 1-Figure 6 The shape of the groove 2016 is hemispherical, spherical or flat-bottomed. The shape of the groove 2016 is gradually concave from the side to the middle for a certain distance, and the transition is smooth, so that the bowl material to be formed is easier to be regularized in place.

[0040] In some embodiments, Figure 2 As shown, the air hole 2013 is tilted from top to bottom at a preset angle to one side of the tangent direction of the circle where the top center of the air hole is located (the connection position of the air hole 2013 and the connecting hole 2014). When the air hole rotates with the rotating disk body, the rotation direction of the tangent of the circle where the top center of the air hole is located is on both sides, but the air hole 2013 is tilted to one side of the tangent direction of the circle where the top center is located, and is tilted to one side of the rotation direction. If it rotates clockwise, it is tilted in the clockwise rotation direction, that is, the air hole 2013 is set with a forward tilt angle from top to bottom in the rotation direction. In other words, the air hole 2013 is first tilted relative to the axis of the center hole 2012, and then tilted from top to bottom in the rotation direction at an angle. In this way, the airflow blown out by the air hole 2013 is not only inclined outwardly relative to the circumference of the dough (powder cake) in the bowl box, 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 hole 2013 can have an upward effect on the circumference of the dough (powder cake) in the bowl box, similar to an inclined stirring rod that has an upward driving force on the stirred material while stirring the material in the circumference, which is beneficial to the forming of the dough (powder cake) in the bowl box.

[0041] Preferably, if Figure 2 As shown, the preset angle of inclination of the blowing hole 2013 from top to bottom along the rotating direction of the rotating disk body 2011 is 15°. At this angle, the forming effect of the cake (powder cake) in the bowl box is better.

[0042] Alternatively, if Figure 5 As shown, a vent hole 217 is provided on the rotating disk body 2011 near the center hole 2012. For some bowl-filled material (powder cake, noodle cake) products, in order to improve the air outlet effect, the vent hole 217 is provided on the rotating disk body. Of course, in other bowl-filled material (powder cake, noodle cake) products, since the bowl box itself has an air outlet, it does not matter if the vent hole is not provided on the rotating disk body 2011.

[0043] like Figure 1-Figure 14 As shown, a specific embodiment of the present invention provides an airflow shaping machine for shaping noodles, rice noodles, vermicelli, noodle threads, etc. during the process of drying and packing into bowls. The produced noodles and powder cakes have neat appearance, no strips or hedgehog-like hairs on the circumference, and are easy to take out of the bowl. The effect is remarkable after use, which completely solves the major problem that has not been solved for many years.

[0044] Specifically, the airflow shaping machine includes a frame 1 and an airflow shaping device 2, and the frame 1 is provided 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 up and down. The airflow shaping device 2 includes the airflow rotating disk 201 described above, a shaping bracket 202, and a plurality of rotating shafts 203 corresponding to the bowl row positions respectively arranged on the shaping bracket 202 through bearings, and the rotating shafts 203 can be arranged in at least one row. The upper end of each rotating shaft 203 is connected to the high-pressure air pipe through a rotating joint 204, and the rotating joint 204 is a high-speed rotating joint, which can make the rotating shaft 203 rotate at a high speed without rotating the high-pressure air pipe. The airflow rotating disk 201 is fixedly connected to the lower end of the rotating shaft 203, and the shaping bracket 202 is provided with a rotating component 205 for driving the rotating shaft 203 to rotate.

[0045] Since the airflow shaping machine 2 in this example includes the aforementioned airflow rotating disk 201, it has the beneficial effects of the airflow rotating disk, which will not be described in detail here. In addition, since the airflow shaping machine also includes a translation device 3 and a lifting device 4, multiple airflow rotating disks 201 can easily approach the noodle bowl box and move with the noodle bowl box, which is convenient for rotating and shaping the moving noodle bowl box.

[0046] In some embodiments, the airflow shaping machine further includes a controller and a signal device 5, and 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 transmission, and the sprocket 501 is rotatably connected to the bearing seat 506 through the sprocket shaft 505. The signal disk 502 is fixedly connected to the sprocket shaft 505. The first sensor 503 is arranged on the bearing seat 506 corresponding to the signal disk 502. When the signal disk 502 rotates to trigger the first sensor 503, the controller controls the translation device 3 to start running, and the second sensor 504 is connected to the sprocket shaft 505. The controller controls the translation device 3 to move accurately horizontally according to the signal of 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 shield 507 covering the outside of the sprocket 501, the signal disk 502, the first sensor 503, and the second sensor 504, so as to protect the signal device 5.

[0047] In this embodiment, two sensors are set up. On the one hand, the first sensor 503 can sense the origin signal according to the rotation of the signal disk 502. On the other hand, the second sensor 504 can directly sense the accurate and real-time rotation speed of the sprocket shaft 505 according to the sprocket shaft 505, so as to facilitate the synchronization of the movement of the translation device 3 and the drying line chain, thereby reducing the failure rate of the shaping equipment and improving the accuracy.

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

[0049] In some embodiments, Figure 8 and Fig. 9 As shown, the rotating assembly 205 includes a driving motor 2051, a driving gear 2052, a driving gear 2053, a transmission gear 2054 and a transmission idler 2055. A transmission gear 2054 is fixedly connected to the outer wall of each rotating shaft 203, and a transmission idler 2055 is meshedly connected between two adjacent transmission gears 2054. The transmission idler 2055 is rotatably connected to the shaping bracket 202 through a bearing, wherein a driving gear 2053 is fixedly connected to each rotating shaft on both sides of the shaping bracket 202, and the driving gear 2053 is meshedly connected to the driving gear 2052 on the output shaft of the driving motor 2051. In this embodiment, the gear transmission is used to enable each transmission shaft to rotate synchronously in the same direction, with high transmission accuracy and efficiency, low noise, and simple maintenance.

[0050] In some embodiments, Fig.12 and Fig.13 As shown, the translation device 3 includes a movable frame 301, a screw rod 302 and a screw motor 303. The airflow shaping device 2 is arranged on the movable frame 301. The movable frame 301 is slidably connected to the frame 1 through a slider. The screw rod 302 is fixedly connected to the frame 1. The screw motor 303 is fixedly connected to the movable frame 301 through a motor bracket 304. The screw motor 303 is transmission-connected to the screw rod 302. By arranging the screw rod 302 and the screw motor 303 to cooperate, the movable frame 301 can be conveniently driven to move in parallel by controlling the screw motor 303, and the movement accuracy is high.

[0051] Based on the above embodiments, Fig.14 As shown, the lifting device 4 includes a lifting assembly fixedly connected to both sides of the movable frame 301, and the lifting assembly includes a cylinder 401, a cylinder bottom 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 through hexagonal cap nuts 404, and the lower parts of the two columns 403 are fixedly connected to both sides of the cylinder bottom plate 402 at intervals, and the bottom of the cylinder is fixedly connected to the middle of the cylinder bottom plate 402. A linear bearing 405 is also slidably connected to each column 403. The two sides of the shaping bracket 202 are fixedly connected to the top of the cylinder 401 and the two linear bearings 405 on the corresponding sides, respectively. The extension and retraction of the cylinder 401 can control the rise and fall of the shaping bracket 202, and the linear bearings 405 can guide the rise and fall of the shaping bracket 202.

[0052] In addition, a compression spring 406 is sleeved on the column 403 between the linear bearing 405 and the cylinder bottom plate 402, so that the rising and falling process of the shaping bracket 202 is smoother. A buffer sleeve 407 is sleeved on the column 403 close to the movable frame 301, which can prevent the shaping bracket 202 from directly colliding with the movable frame 301 after rising, and play 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 of the photoelectric switch sensor (first sensor 503) is transmitted to the controller to drive the screw motor 303 in the translation device 3 to start operation. The rotary photoelectric encoder (second sensor 504) sends a high-frequency pulse signal, which can accurately control the operating speed of the screw motor 303. The screw motor 303 converts the rotational motion into linear motion through the screw 302, so that the walking speed of the movable frame 301 and the walking speed of the drying line bowl row are synchronized. After the movable frame 301 starts to move, the cylinder 401 of the lifting device 4 installed on the movable frame 301 works, and the airflow shaping device 2 is lowered to the top of the bowl row. The airflow rotating disk 201 rotates and gradually approaches the noodle bowl box 6. The controller controls the pneumatic solenoid valve connected to the high-pressure air pipe to work through the rotary joint 204 to pass compressed air into the airflow rotating disk 201. Through the multiple blowing holes 2013 on the airflow rotating disk 201, a high-speed rotating airflow is formed on the circumference of the bowl box 6 filled with materials. The high-speed rotating airflow quickly rotates the materials that are not loaded into the bowl box 6 into the bowl box 6. The airflow rotating disk 201 continues to descend to rotate and compress the materials. Under the action of the high-speed rotating airflow, there are no hedgehog-like strips on the circumference of the compressed dough (powder cake). After the work is completed, the pneumatic solenoid valve stops supplying air, the cylinder of the lifting device 4 rises, the screw motor 303 runs in the reverse direction, and the movable frame 301 quickly returns to the starting position to wait for the next signal, and so on.
