[0044] Reference Figure 1 As shown, this application embodiment provides a shaping and polishing device 10, including:

[0045] The housing 100 has a shaping cavity S1, and a feed inlet 110, an air inlet 120, a discharge outlet 130 and an air outlet 140 communicating with the shaping cavity S1.

[0046] A shaping and polishing assembly 200 is disposed within the shaping cavity S1. The shaping and polishing assembly 200 includes a rotating shaft 210 and a polishing mechanism 220. The rotating shaft 210 is rotatable, and the polishing mechanism 220 is disposed on the rotating shaft 210. The air inlet 120 is located below the shaping and polishing assembly 200, and the air outlet 140, the feed inlet 110, and the discharge outlet 130 are located above the shaping and polishing assembly 200.

[0047] Grinding tooth 300 is arranged around the grinding mechanism 220 and forms a grinding gap S2 with the grinding mechanism 220; the grinding tooth 300 is configured to be rotatably connected to the housing 100.

[0048] In the technical solution of this application embodiment, the raw material enters the shaping cavity S1 from the feed port 110; the rotating shaft 210 drives the grinding mechanism 220 to rotate, and uses centrifugal force to send the raw material into the grinding gap; in the grinding gap, the grinding mechanism 220 and the toothed grinding part 300 collide and rub against the raw material to achieve grinding and shaping; gas enters from the air inlet 120, and blows the ground material upward through the shaping and grinding assembly 200, and discharges from the air outlet 140, and the finished material is discharged from the discharge port 130. When the grinding mechanism 220 rotates, the toothed grinding part 300 is rotatably connected to the housing 100, so it can be passively rotated when the grinding mechanism 220 rotates, thereby reducing the probability of the grinding mechanism 220 jamming due to raw material accumulation, which helps to improve the production efficiency of grinding and shaping; in addition, since the toothed grinding part 300 is rotatable, it also helps to reduce the wear of the toothed grinding part 300, reduce the replacement frequency of the toothed grinding part 300, and help to improve production efficiency.

[0049] It should be noted that during the grinding process, the material (the raw material that has just entered or is being ground) rubs against the grinding mechanism 220 and the toothed grinding part 300. With the help of friction, the toothed grinding part 300 rotates passively, which helps to loosen the material in the grinding gap and reduces the probability of material accumulation.

[0050] As an optional implementation of the above embodiments, the gear grinding member 300 is configured in a ring shape and is configured to rotate about the axis of the rotating shaft 210. In the embodiments, such as Figure 2 As shown, the grinding part 300 is in the shape of a ring and is arranged around the shaping and grinding assembly 200. The grinding mechanism 220 can grind the raw material together with the grinding part 300 when it rotates to any circumferential position. When the grinding part 300 is passively rotated, it rotates around the axis of the rotating shaft 210. That is, the grinding mechanism 220 and the grinding part 300 rotate coaxially.

[0051] As an optional implementation of the above embodiments, such as Figure 3 As shown, the shaping and polishing equipment 10 further includes a first sleeve 710 and a second sleeve 720; the first sleeve 710 and the second sleeve 720 are disposed on the housing 100 and spaced apart from each other in the axial direction of the rotating shaft 210; the opposite ends of the gear grinding member 300 are respectively rotatably engaged with the first sleeve 710 and the second sleeve 720. In an embodiment, the gear grinding member 300 extends along the axial direction of the rotating shaft 210 and has two axial ends, which are respectively rotatably engaged with the first sleeve 710 and the second sleeve 720.

[0052] In this embodiment, the first sleeve 710 and the second sleeve 720 constrain the gear grinding member 300 in the axial direction. For example... Figure 4As shown, the first sleeve 710 and the second sleeve 720 adopt the same structure, both including a sleeve body 711 and a limiting protrusion 712 protruding from the first axial end face 7111 of the sleeve body 711; the second axial end face of the gear grinding part 300 abuts against the first axial end face 7111 of the sleeve body 711, axially limiting the gear grinding part 300; and the inner wall surface of the gear grinding part 300 rotates with the peripheral side surface 7121 of the limiting protrusion 712, so that the gear grinding part 300 can perform circumferential motion.

[0053] In some embodiments, at least one of the first sleeve 710 and the second sleeve 720 can be fixed to the housing 100 by a hinge. The hinge can be pulled up and closed for easy installation. The hinge serves a positioning function and also serves to fix the first sleeve 710 and the second sleeve 720. For example, the first sleeve 710 has a threaded hole, and the hinge is connected to the first sleeve 710 by a threaded part to facilitate the replacement of the gear grinding part 300.

[0054] In some embodiments, the second sleeve 720 may be configured to rotate about the housing, and the first sleeve 710 may be fixed to the housing.

[0055] In some embodiments, the first sleeve 710 and the second sleeve 720 may also be provided with lifting holes, and the first sleeve 710 and the second sleeve 720 may be hoisted and installed on the housing 100 by means of threaded parts.

[0056] As an optional embodiment of the above embodiments, at least one of the first sleeve 710 and the second sleeve 720 is provided with a lubrication hole 713; the lubrication hole 713 is filled with a graphite core. In this embodiment, since the gear grinding member 300 can slide relative to the sleeve, in order to reduce friction and wear, at least one of the first sleeve 710 and the second sleeve 720 is provided with a lubrication hole 713; the lubrication hole 713 is filled with a graphite core and has a lubrication function.

[0057] In an embodiment, such as Figure 4 As shown, the first sleeve 710 has several lubrication holes 713 on both the sleeve body 711 and the limiting protrusion 712, and each lubrication hole 713 contains a graphite core. The array arrangement of the lubrication holes 713 is not specifically limited and can be as follows: Figure 4 The arrangement shown is regular, but it can also be set to an unordered arrangement.

[0058] In addition, in some cases, the shaping and polishing equipment 10 can be used to polish graphite raw materials. During the polishing process, the graphite core is prone to run out of the lubrication hole 713 or is reduced due to wear. The graphite raw material can replenish the graphite core that has been discharged from the lubrication hole 713, which is beneficial to improving the lubrication effect.

[0059] To further reduce the risk of the grinding mechanism 220 jamming due to raw material accumulation, the grinding mechanism 220 in this embodiment is divided into zones. For example... Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, as an optional implementation of the above embodiments, the polishing mechanism 220 includes:

[0060] The first grinding mechanism 221 includes a first turntable 2210 and a first grinding structure 2213; the first grinding structure 2213 is disposed on the first turntable 2210; the first turntable 2210 is disposed on the rotating shaft 210; the first grinding structure 2213 and the gear grinding part 300 have a first grinding gap S21;

[0061] The first grinding mechanism 222 includes a second turntable 2220 and a second grinding structure 2223; the second grinding structure 2223 is disposed on the second turntable 2220, and the second turntable 2220 is disposed on the rotating shaft 210; the second grinding structure 2223 and the gear grinding part 300 have a second grinding gap S22.

[0062] The first turntable 2210 is located above the second turntable 2220 in the axial direction of the rotating shaft 210, and the first turntable 2210 has a first material leakage gap S41.

[0063] In some embodiments of this application, due to the upward airflow, heavier materials fall through the first material leakage gap S41 of the first turntable 2210 onto the second turntable 2220, where they are ground by the second grinding gap S22 between the second grinding structure 2223 and the toothed grinding member 300. Lighter materials remain on the first turntable 2210 and are ground by the first grinding gap S21 between the first grinding structure 2213 and the toothed grinding member 300. The lighter materials are shaped and ground within the first grinding gap S21, while the heavier materials are shaped and ground within the second grinding gap S22. This partitioned grinding method helps to prevent material accumulation.

[0064] In addition, after the heavier materials are shaped and polished, they can enter the first polishing gap S21 for further shaping and polishing under the action of airflow, which is beneficial to the consistency of the finished materials in terms of appearance and particle size.

[0065] For example, in some embodiments, reference is made to... Figure 2As shown, the first turntable 2210 can be an upper turntable, and the second turntable 2220 can be a middle turntable. In some other embodiments, the first turntable 2210 can be a middle turntable, and the second turntable 2220 can be a bottom turntable. In some other embodiments, the first turntable 2210 can be an upper turntable, and the second turntable 2220 can be a bottom turntable.

[0066] As an optional implementation of the above embodiments, the arrangement density of the first grinding structure 2213 is less than the arrangement density of the second grinding structure 2223. In this embodiment, the arrangement density of the first grinding structure 2213 is less than the arrangement density of the second grinding structure 2223, and the first turntable 2210 is located above the second turntable 2220. Heavier materials fall into the grinding area of ​​the second turntable 2220. The relatively more distributed second grinding structures 2223 grind the heavier materials, while the relatively less distributed first grinding structures 2213 grind the lighter materials. This allows for grinding of raw materials of different weights with different intensities, thereby achieving fine grinding of the raw materials.

[0067] In some embodiments, the first grinding structures 2213 are spaced apart to form a first material leakage gap S41, through which some heavier materials can fall into the grinding area of ​​the second turntable 2220; while some lighter materials are ground in the grinding area of ​​the first turntable 2210. Gas is blown into the shaping and grinding equipment 10 from below. Under the action of the airflow, lighter particles are retained in the grinding area of ​​the first turntable 2210, while heavier particles can fall from the first material leakage gap S41 into the grinding area of ​​the second turntable 2220 under the action of gravity. After being ground, the heavier particles have less gravity and are blown into the grinding area of ​​the first turntable 2210 for further grinding under the action of the airflow, thereby ensuring that the finished product material is more uniform in appearance and particle size than the finished product material ground in the prior art.

[0068] In the technical solutions of the above embodiments, the arrangement density can be understood as the number of grinding structures arranged within a certain area. In the shaping and grinding equipment 10, the grinding structures need to work together with the toothed grinding parts 300 to grind the material, so the grinding structures are set at the circumferential edge of their respective turntables; therefore, the arrangement density can be understood as the number of grinding structures arranged around the turntable. For example, for the middle turntable and the bottom turntable, 6 grinding structures are arranged around the middle turntable.

[0069] As an optional implementation of the above embodiments, the first turntable 2210 includes a first disc body 2211 and a plurality of first rods 2212 spaced circumferentially along the first disc body 2211, the first rods 2212 extending radially along the rotating shaft 210; the first grinding structure 2213 is disposed on the first rods 2212; the second turntable 2220 includes a second disc body 2221 and a plurality of second rods 2222 spaced circumferentially along the second disc body 2221, the second rods 2222 extending radially along the rotating shaft 210; the second grinding structure 2223 is disposed on the second rods 2222; the first rods 2212 and the second rods 2222 are offset circumferentially along the rotating shaft 210.

[0070] In one embodiment, a plurality of first rods 2212 are spaced apart circumferentially to form a first material leakage gap S41. Viewed in a plane perpendicular to the axial direction of the rotating shaft 210, the second rods 2222 and the first rods 2212 are staggered circumferentially to improve the grinding uniformity of the finished material. In some embodiments, viewed in a plane perpendicular to the axial direction of the rotating shaft 210, the width of the second rod 2222 is smaller than the width of the first rod 2212, making the first material leakage gap S41 larger and preventing the accumulation of medium and heavy materials.

[0071] As an optional implementation of the above embodiments, the grinding mechanism 220 further includes a third grinding mechanism 223, which includes a third turntable 2231 and a third grinding structure 2232; the third grinding structure 2232 is disposed on the third turntable 2231 and has a third grinding gap S23 with the gear grinding part 300; wherein, the third turntable 2231 is disposed on the rotating shaft 210 and is located below the second turntable 2220 in the axial direction of the rotating shaft 210; the second turntable 2220 has a second material leakage gap S42.

[0072] In this embodiment, the shaping and polishing assembly 200 includes an upper turntable (first turntable 2210), a middle turntable (second turntable 2220), and a bottom turntable (third turntable 2231). Under the influence of airflow and the gravity of the raw material, heavy materials enter the bottom region S53 of the third turntable 2231 through the first material leakage gap S41 and the second material leakage gap S42, where they are polished by the third polishing structure 2232 and the toothed grinding element 300. Medium-weight materials enter the middle region S52 of the second turntable 2220 through the first material leakage gap S41, where they are polished by the second polishing structure 2223 and the toothed grinding element 300. Light materials are polished in the upper region S51 of the first turntable 2210 by the first polishing structure 2213 and the toothed grinding element 300. Under the influence of airflow and gravity, lightweight materials are ground by the first grinding structure 2213 in the upper region S51. Medium and heavy materials fall into the middle region S52 through the first discharge gap S41. The medium materials are ground by the second grinding structure 2223 in the middle region S52, while the heavy materials continue to fall into the bottom region S53 through the second discharge gap S42 and are ground by the third grinding structure 2232. After grinding, the heavy materials become lighter and float to the middle region S52, where they continue to be ground by the second grinding structure 2223. After grinding, the medium materials in the middle region S52 become lighter and float to the upper region S51, where they continue to be ground by the first grinding structure 2213. Finally, the materials are basically formed into finished products with a more uniform appearance and particle size.

[0073] In some embodiments, the first grinding structure 2213 is the grinding surface. That is, the edge of the first rod 2212 away from the rotating shaft 210 is the grinding surface. Unlike the second and third grinding structures 2223 and 2232, which are grinding components that can be detached from their respective turntables, the first grinding structure 2213 is a grinding surface with a directly curved edge. This is because the second and third grinding structures 2223 and 2232 need to handle medium or high-quality materials, resulting in more severe wear and requiring frequent replacement or maintenance; while the first grinding structure 2213 mainly performs slight shaping on materials, with less wear and a relatively lower replacement frequency, thus allowing for a directly curved grinding surface. In this embodiment, the edges of the grinding component are rounded to allow for a smooth transition of the particles during grinding.

[0074] As an optional implementation of the above embodiments, the third turntable 2231 is a sealed-bottom turntable. In this embodiment, the third turntable 2231 is the turntable on the lowest side of the shaping and polishing assembly 200. The sealed-bottom turntable design aims to reduce the amount of raw material falling into the air inlet 120, thereby reducing the risk of the air inlet 120 becoming blocked. A sealed-bottom turntable means that its third disc body does not have any hollowed-out gaps.

[0075] In the technical solutions of the embodiments, the first disc 2211, the second disc 2221, and the third turntable 2231 can be integrally formed with the rotating shaft 210. In some embodiments, the first disc 2211, the second disc 2221, and the third turntable 2231 can be welded to the rotating shaft 210. In some embodiments, the first disc 2211, the second disc 2221, and the third turntable 2231 can be fixed to the rotating shaft 210 by threaded parts; the rotating shaft 210 is provided with axially spaced protrusions, the first disc 2211, the second disc 2221, and the third turntable 2231 are sleeved on the rotating shaft 210 and respectively abut against the corresponding protrusions; the protrusions are provided with a plurality of threaded holes arranged circumferentially, and the first disc 2211, the second disc 2221, and the third turntable 2231 are provided with a plurality of threaded holes circumferentially; the threaded holes are tightened one by one by threaded parts so that the first disc 2211, the second disc 2221, and the third turntable 2231 are fixedly connected to the rotating shaft 210 and can be disassembled for disassembly and maintenance.

[0076] Furthermore, in the technical solutions of this application embodiment, the shaping and grinding assembly 200 can also be configured with three or more turntables according to the quality requirements of the material, achieving more zones; in some embodiments, the lower grinding structure has a higher arrangement density than the upper grinding structure. In the shaping and grinding assembly 200, the upper turntable grinding structure is sparsely distributed, while the lower turntable grinding structure is densely distributed. The upper layer of material is lighter and has a smaller particle size, while the lower layer of material is heavier and has a larger particle size. The multi-layer turntables can achieve layered grinding of the material, improving the shaping yield and reducing the over-grinding rate. The grinding structure can be configured as an embedded design and fixed to the disc body by threaded parts such as screws, making disassembly and replacement convenient.

[0077] In this embodiment, the grinding gap can be set according to the required particle size.

[0078] As an optional implementation of the above embodiments, such as Figure 1 As shown, the housing 100 also has an air outlet 140 communicating with the shaping cavity S1; the air outlet 140 is located above the discharge port 130; the shaping and grinding equipment 10 also includes a grading wheel assembly 400, which includes grading wheels 410 rotatably disposed within the shaping cavity S1; in the axial direction of the rotating shaft, the grading wheels 410 are located between the discharge port 130 and the air outlet 140. In an embodiment, the grading wheel assembly 400 is used to generate a centrifugal airflow field within the shaping cavity S1 to sort the finished material. Some over-crushed, lightweight finished materials float upwards in the central region of the shaping cavity S1 due to their light weight and are carried into the air outlet 140 by the grading wheel assembly 400 and discharged; while heavier finished materials float upwards on both sides of the shaping cavity S1 (near the wall of the housing 100) and are discharged through the discharge port 130.

[0079] The fan will continuously carry the airflow out of the air outlet. The classifying wheel plays the role of screening materials smaller than the standard particle size. Larger or standard particle size materials will return to the shaping chamber for re-grinding or enter the discharge port.

[0080] like Figure 8 As shown, the grading wheel assembly 400 includes four grading wheels 410 and four grading motors 420, with each grading motor 420 connected to a corresponding fan wheel. The grading wheels 410 are located within the shaping chamber S1 to generate a centrifugal airflow field within the chamber. The rotation direction of the grading wheels 410 is referenced... Figure 8 As shown, the flow field of material particles in the shaping cavity S1 is balanced and stabilized.

[0081] There is no specific limit to the number of graded wheels in a graded wheel set 400; it can be one, two, three, or more.

[0082] As an optional implementation of the above embodiments, such as Figure 1 and Figure 9 As shown, the shaping and polishing equipment 10 also includes an inner cylinder 500; the inner cylinder 500 is disposed within the shaping cavity S1, located between the shaping and polishing assembly 200 and the grading wheel set 400; the inner cylinder 500 has a hollow cavity 511 extending through the upper and lower parts of the rotating shaft 210 in the axial direction; a gap S3 exists between the inner cylinder 500 and the housing 100. In this embodiment, the inner cylinder 500 is disposed between the shaping and polishing assembly 200 and the grading wheel set 400, which serves to stabilize the internal airflow. On the other hand, in the rotating airflow generated by the grading wheel assembly 400, the heavier finished materials move toward the wall of the shell 100 and enter the gap S3 between the inner cylinder 500 and the shell 100, and float upwards; while some over-crushed lighter finished materials, due to their light weight, do not move toward the wall of the shell 100 under the action of centrifugal force, but are retained in the middle area of ​​the shaping cavity S1. Under the action of airflow, they float upwards through the hollow cavity 511 and are carried into the air outlet 140 by the grading wheel assembly 400.

[0083] In addition, during feeding, excessively fine or light materials in the raw material will be lifted upwards through the hollow cavity 511 by the airflow and carried into the air outlet 140 by the classifying wheel assembly 400. Heavier materials, on the other hand, fall into the shaping and grinding assembly 200 for grinding.

[0084] like Figure 9As shown, the inner cylinder 500 includes a cylinder body 510 and a plurality of support rods 540 arranged around the cylinder body 510. The plurality of support rods 540 are connected to the housing 100 to fix the inner cylinder 500 within the shaping cavity S1. In some embodiments, the axis of the inner cylinder 500 coincides with or substantially coincides with the center line of the rotating shaft 210. In some embodiments, the axis of the inner cylinder 500, the center line of the rotating shaft 210, and the center of the shaping cavity S1 coincide with or substantially coincide with each other. In some embodiments, the cylinder body 510 further includes an outer ring 530, the outer ends of the support rods 540 are connected to the outer ring 530, and the outer ring 530 is fixedly connected to the housing 100.

[0085] As an optional implementation of the above embodiments, a guide plate 520 is provided within the gap S3; and the guide plate 520 extends towards the discharge port 130 in a curved manner. In this embodiment, the heavier finished product rises along the gap S3 due to centrifugal force. With the guide plate 520 located within the gap S3, the heavier finished product enters the discharge port 130 and is discharged under the guidance of the guide plate 520, thus preventing the finished product from accumulating at the discharge port 130.

[0086] like Figure 9 As shown, the guide plate 520 is located on the outer wall of the inner cylinder 500, corresponding to the position of the discharge port 130, and extends fully toward the discharge port 130 to guide the heavier finished material to the discharge port 130.

[0087] In some other embodiments, the drainage plate 520 is disposed on the inner wall surface of the housing.

[0088] As an optional implementation of the above embodiments, such as Figure 1 As shown, the discharge port 130 is inclined downwards. In this embodiment, the downward inclination of the discharge port 130 facilitates the discharge of finished materials and prevents them from accumulating in the discharge port 130. The discharge port is set at a downward inclination angle; this angle can be the angle between the bottom wall of the discharge port and the vertical direction, such as 80°, 75°, or 60°.

[0089] As an optional implementation of the above embodiments, such as Figure 1 As shown, the shaping and polishing equipment 10 further includes a drive mechanism 600, which is configured to drive the rotating shaft 210 to rotate. In some embodiments, the drive mechanism 600 includes a shaping motor that drives the rotating shaft 210 to rotate. In some embodiments, the drive mechanism 600 includes a shaping motor and a transmission mechanism, with the shaping motor connected to the rotating shaft 210 via the transmission mechanism. For example, the transmission mechanism can be a gear reduction mechanism, a coupling, etc. In some embodiments, the shaping motor's transverse shaft is connected to the rotating shaft via a coupling that can change the direction of rotation, and the rotating shaft is driven by adjusting the installation angle of the coupling. In this embodiment, the output speed of the motor can be adjusted to adjust the sphericity of the finished material.

[0090] In some embodiments, the shaping and polishing equipment 10 includes a power compartment, within which a drive mechanism 600 is provided. In other embodiments, the drive mechanism 600 may also be externally located outside the housing 100.

[0091] Compared to existing shaping machines with a feed particle size of 0-5mm and a maximum capacity of 0.5 tons per hour, the shaping and grinding equipment of this invention can achieve a capacity of 3-5 tons per hour, while ensuring the material crushing effect and material particle size index.

[0092] Based on the shaping and polishing equipment 10 provided in the above embodiments, this application also proposes a shaping and polishing method. The polishing method includes:

[0093] The fan is started to draw airflow from the air inlet 120 into the shaping cavity S1;

[0094] The raw material conveying mechanism is activated to feed the raw material from the feed inlet 110 into the shaping cavity S1.

[0095] Control the rotation of the rotating shaft 210.

[0096] When using the shaping and polishing equipment 10 of this application embodiment, the fan is started, and the airflow is introduced into the shaping cavity S1 from the bottom and exits from the bottom to the top; the raw material conveying mechanism is started, and the raw material is sent into the shaping cavity S1 from the feed port 110. Since the feed port 110 is above the shaping and polishing component 200, the raw material falls onto the shaping and polishing component 200; when the rotating shaft 210 is started, the raw material enters the polishing gap between the polishing mechanism 220 and the gear grinding part 300 for polishing by using centrifugal force; under the action of the airflow, the finished material floats to the discharge port 130 and is discharged from the shaping cavity S1.

[0097] A specific shaping and polishing process using the polishing method of this application embodiment can be as follows:

[0098] 1) The shaping machine starts to achieve continuous shaping; the blower starts, the raw material conveying mechanism starts, and the rotating shaft 210 starts; the grading wheel group 400 starts.

[0099] 2) Material enters the shaping chamber S1 through the feed inlet 110. Large and heavy particles fall into the lower rotating disc as the multi-layer rotating discs rotate. The particles collide and rub against the grinding parts fixed on the lower disc and the outer toothed grinding parts 300, eliminating sharp edges and corners. The rounded corners of the grinding parts ensure a smooth transition during grinding. Medium-sized and generally heavy particles enter the middle rotating disc for grinding. Lighter particles that require shaping enter the upper rotating disc for grinding.

[0100] 3) After grinding, the material that meets the particle size requirements is blown into the air inlet 120 and suspended. Under the action of the stirring and rotating flow field, due to the tangential force, it enters the discharge port 130 under the guidance plate 520.

[0101] 4) After the fine material enters the shaping chamber S1 through the feed inlet 110, it enters the inner cylinder 500 in the middle of the shaping machine under the drive of the turntable, and floats up under the action of the air blown in through the air inlet 120, and is carried into the air outlet 140 by the classifying wheel 410.

[0102] 5) The crushed material particles after grinding are relatively light in size and weight. Under the action of the air blown in through the air inlet 120, they float upwards and float upwards along the gap between the inner wall of the shaping machine and the inner cylinder 500. They are then carried into the air outlet 140 by the classifying wheel 410.

[0103] The entire cosmetic procedure is continuous and can be fully automated.

[0104] In some embodiments of this application, a screw electric feeder is connected before the feed inlet 110, and the screw controls the uniform and continuous feeding. The rear end of the discharge outlet 130 is connected to a buffer chamber via an electric valve, and the buffer chamber has its own pressure relief valve. The rear end of the air outlet 140 is connected to an induced draft fan, and the collection of small and light particulate materials is achieved by controlling the airflow intensity.

[0105] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the content of the specification and drawings of this application under the concept of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
