Description

Technical Field

[0001] This invention relates to the field of mineral wool fiber manufacturing equipment technology, and in particular to a lightweight mineral wool fiber centrifugal fiber forming device and its usage method. Background Technology

[0002] In the field of mineral wool fiber production, centrifugal fiber forming has become a core technology for producing high-performance mineral wool fibers due to its efficient and continuous fiber forming characteristics. Mineral wool fibers, with their excellent thermal insulation properties, Class A fire resistance, and good acoustic absorption characteristics, have achieved large-scale application in building exterior wall insulation systems, industrial high-temperature kiln insulation layers, and petrochemical pipeline insulation projects. As the core execution unit of this process, the mechanical stability and control precision of the centrifugal fiber forming device directly determine the uniformity of the diameter distribution of the mineral wool fibers and the overall efficiency of the production line.

[0003] Traditional centrifugal fiber forming equipment has certain limitations in design and function. Firstly, when injecting molten raw material into the centrifugal rollers, the lack of an effective sealing structure allows the material to easily flow out of the nozzles, leading to waste and potentially affecting the normal operation of the equipment. Secondly, during the centrifugal fiber forming process, fiber collection is often uneven, resulting in uneven fiber accumulation in the collection tank, affecting subsequent processing and use. Furthermore, traditional centrifugal fiber forming equipment is inefficient in cooling, failing to quickly and effectively cool the ejected fibers, thus affecting fiber forming quality and production efficiency.

[0004] To address the above problems, this invention proposes a lightweight mineral wool fiber centrifugal fiber forming device and its usage method. Summary of the Invention

[0005] The purpose of this invention is to solve the shortcomings of existing methods that easily lead to waste, clogging of nozzles, and disordered accumulation of fibers after centrifugation when raw materials are injected into centrifugal rollers. Therefore, this invention proposes a lightweight mineral wool fiber centrifugal fiber forming device and its usage method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lightweight mineral wool fiber centrifugal fiber forming device includes a base, and a centrifuge box is fixed on the top of the base;

[0008] A centrifugal roller, rotatably connected to the inner wall of the top of the centrifuge chamber, has multiple sets of annularly distributed spray holes on its outer wall from top to bottom, and also includes:

[0009] A closing ring, which is slidably fitted onto the outer wall of the centrifugal roller, is used to close the spray nozzle;

[0010] A fixed ring is fixedly sleeved on the outer wall of the centrifugal roller, and a centrifugal block is slidably connected to its top. The centrifugal block is connected to the closed ring by a pull rope. When the speed of the centrifugal roller reaches the threshold, the centrifugal block is moved outward by centrifugal force and pulls the closed ring upward by the pull rope to open the spray hole.

[0011] A collection plate is slidably disposed on the top of the base, and a collection groove is provided on its top;

[0012] The reciprocating drive mechanism includes a track groove at the bottom of a fixed ring, a pin at the top of a sliding rod, a track groove that slides with the pin, a rack, a spur gear, a gearbox, and a drive shaft. The sliding rod drives the spur gear to rotate through the rack. After the gearbox adjusts the speed, it drives the rotating disk to rotate through the drive shaft. The pin at the bottom of the rotating disk engages with the sliding groove of the collecting plate, causing the collecting plate to reciprocate to evenly lay the fibers.

[0013] As a further improvement to the above technical solution:

[0014] The fixed ring has a guide wheel at its top, and a limiting groove on its outer wall. The pull rope passes through the limiting groove and connects to the closed ring. An air outlet ring is fixed to the top inner wall of the centrifuge, and its bottom has multiple sets of first through holes. A cooling water ring is fixed to the inner wall of the centrifuge, and its bottom has multiple sets of second through holes. A conical discharge ring is fixed inside the centrifuge, and its inner wall has an inclination angle of 30°-60°. Its bottom end is connected to a discharge pipe, which is correspondingly arranged with a collection tank. A transmission pipe is coaxially fixed to the top of the centrifugal roller, and a first bevel gear is fixed to the outer wall of the transmission pipe. The first bevel gear is connected to the second bevel gear of the drive motor. The centrifuge chamber is equipped with gear meshing. A U-shaped groove tube is fixed to the top of the centrifuge chamber. A hopper is rotatably connected to the top of the transmission tube and is fixed to the top of the centrifuge chamber by an L-shaped support rod. The hopper and the U-shaped groove tube are engaged. A storage tank is provided on the top of the base. A leakage hole is provided at the bottom of the collection tank. The storage tank is connected to a cooling water ring through a pump. A stop block is fixed to the outer wall of the fixing ring by bolts to limit the reset position of the centrifuge blocks. A protective box is fixed to one side of the centrifuge chamber, covering the rack, spur gear and gearbox. A protective mesh is slidably connected to the top of the collection plate and is sleeved on the outer wall of the discharge pipe.

[0015] This application discloses a method of using a lightweight mineral wool fiber centrifugal fiber forming device, comprising the following steps:

[0016] S1. Molten raw material injection and centrifugal fiber formation: Molten raw material is injected into the centrifugal roller through a U-shaped groove tube. The sealing ring closes the nozzle to store the raw material. When the drive motor is started, it drives the transmission tube and the centrifugal roller to rotate through the meshing of the first bevel gear and the second bevel gear. After the centrifugal roller reaches the threshold speed, the centrifugal block moves outward under centrifugal force and moves the sealing ring upward through the pull rope, releasing the nozzle closure and allowing the raw material to be centrifugally thrown out through the nozzle to form fibers.

[0017] S2. Dual cooling system operates synchronously: The blower injects cold air into the air outlet ring through the air injection hole. The cold air is blown downward through the first through hole to cool and throw out the raw material and guide the fiber downward. At the same time, the pump injects cooling water into the cooling water ring through the liquid injection pipe. The cooling water is sprayed onto the conical discharge ring through the second through hole, forming a water curtain on its inner wall to further cool the passing fiber.

[0018] S3. Uniform fiber collection control: Fibers fall into the collection plate through the discharge pipe; when the fixed ring rotates, the sliding rod is driven to move back and forth through the engagement of the pin and the track groove. The sliding rod drives the spur gear to rotate through the meshing of the rack and the spur gear. After the gearbox adjusts the speed, it outputs through the drive shaft to drive the rotating disk to rotate. The rotating disk drives the collection plate to move back and forth through the engagement of the pin and the sliding groove, so that the fibers are alternately folded and laid out.

[0019] S4. Cooling water circulation and fiber removal: Water and fibers in the conical discharge ring fall into the collection tank and enter the storage tank through the leakage hole. The cooling water is then pumped back into the cooling water ring for recycling. The protective mesh is pushed upward to remove it from the fibers and the fibers are removed from the collection tank.

[0020] Beneficial effects: In this invention, a fixed ring is fixedly sleeved on the outer wall of the centrifugal roller, and a closed ring is slidably sleeved on the outer wall of the centrifugal roller. Multiple centrifugal blocks are slidably connected to the top of the fixed ring. Each of the multiple centrifugal blocks has a pull rope fixed on the side near the centrifugal roller. The bottom end of the pull rope is fixedly connected to the closed ring located at the top layer. As the centrifugal roller rotates, the centrifugal blocks move outward under the action of centrifugal force. The centrifugal blocks drive the closed ring to move upward through the pull rope, releasing the seal on the nozzle. At this time, the raw material inside the centrifugal roller is thrown out to the outside through the nozzle under the action of centrifugal force, and then the raw material is drawn into fibers. Thus, when the centrifugal roller is stationary, the raw material can be prevented from leaking out of the centrifugal roller.

[0021] In this invention, a pin is fixed to the top of the sliding rod, a track groove is provided at the bottom of the fixing ring, a rack is fixed to one side of the sliding rod, a spur gear is fixed to the input shaft of the gearbox, the output shaft of the gearbox is fixedly connected to the top of the drive shaft, a rotating disk is fixed to the bottom of the drive shaft, a pin is fixed to the bottom of the rotating disk off-center, and a sliding groove is provided at the top of the collecting plate. When the fixing ring rotates, the sliding rod is driven to reciprocate linearly through the cooperation of the pin and the track groove. The sliding rod drives the spur gear to rotate through the meshing between the rack and the spur gear, which in turn drives the rotating disk to rotate. The rotating disk can drive the collecting plate to reciprocate linearly through the cooperation of the pin and the sliding groove, thereby enabling the fibers falling from the discharge pipe to be alternately folded and laid on the collecting plate.

[0022] In this invention, a conical discharge ring is fixed inside the centrifuge chamber, and a discharge pipe penetrating the inner wall of the bottom of the centrifuge chamber is fixed at the bottom of the conical discharge ring. When the centrifugal roller rotates to centrifuge and form fibers, the fibers fall onto the inner wall of the conical discharge ring and are guided to the center by the inner wall of the conical discharge ring and discharged through the discharge pipe, which facilitates the collection of fibers later. In addition, the cooling water sprayed by the cooling water ring falls onto the conical discharge ring to form a water curtain. Therefore, the conical discharge ring guides the fibers so that the cooling water comes into contact with the fibers for water cooling.

[0023] In this invention, the nozzles can be sealed before centrifugal fiber formation to avoid waste of raw materials and clogging of the nozzles. When the centrifugal roller rotates to form fibers, the collecting plate can be driven to move back and forth in a straight line to collect the fibers in an orderly manner in the collecting tank, which facilitates the uniform processing of the fibers in the later stage.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Example 1: Refer to Figure 1 and Figure 2 The centrifugal fiber forming device relates to the field of fiber processing equipment technology. The device mainly includes a base 1, a centrifuge box 2, a centrifugal roller 8, a sealing structure, a reciprocating structure, a cooling structure, and a collection structure.

[0036] Reference Figure 2 and Figure 3 The base 1 serves as the supporting foundation for the entire device, and the centrifuge chamber 2 is fixed to its top by support legs. The centrifuge chamber 2 is the main working chamber of the device, and key components for centrifugal fiber formation are installed inside.

[0037] Reference Figures 2-4 Centrifuge roller 8 is rotatably connected to the top inner wall of centrifuge chamber 2 via a rotating bearing. Centrifuge roller 8 is the core component for centrifugal fiber formation, and its outer wall is provided with multiple nozzle groups from top to bottom. Each nozzle group consists of multiple nozzle holes 9 arranged in a ring on the outer wall of centrifuge roller 8. Molten raw material is injected into the centrifuge roller 8 through the cooperation of U-shaped groove tube 7 and hopper. Under the action of centrifugal force, the raw material is thrown out from the nozzle holes 9 to form fibers.

[0038] Reference Figure 3 and Figure 4To prevent the molten material from flowing out of the nozzle 9 when it is injected into the centrifugal roller 8, the present invention provides a sealing structure on the outer wall of the centrifugal roller 8. This sealing structure mainly includes multiple sealing rings 10 slidably fitted onto the outer wall of the centrifugal roller 8. The cross-sectional shape of the sealing rings 10 can be rectangular, trapezoidal, or semi-circular. The trapezoidal cross-section enhances the sealing fit with the outer wall of the centrifugal roller 8, while the semi-circular cross-section reduces sliding friction resistance. The sealing rings 10 correspond to the nozzle assembly and are used to seal the corresponding nozzles 9.

[0039] Reference Figure 3 and Figure 4 The sealing structure also includes a fixing ring 12 fixedly sleeved on the outer wall of the centrifugal roller 8. Adjacent sealing rings 10 are fixedly connected by multiple fixing rods 11, thus forming a single unit. Multiple centrifugal blocks 13 are slidably connected to the top of the fixing ring 12. Each centrifugal block 13 has a pull rope 17 fixed to its side near the centrifugal roller 8. The bottom ends of the pull ropes 17 pass through the fixing ring 12 and are fixedly connected to the uppermost sealing ring 10. When the centrifugal roller 8 is stationary, the multiple sealing rings 10 reset under gravity, sealing the nozzle 9. When the centrifugal roller 8 begins to rotate, as the rotational speed gradually increases, when the speed reaches a certain threshold, the centrifugal blocks 13 move outward under centrifugal force. The centrifugal blocks 13, through the pull ropes 17, drive the sealing rings 10 upward, thereby releasing the seal on the nozzle 9. At this time, the raw material inside the centrifugal roller 8 is thrown outward through the nozzle 9 under the action of centrifugal force, and then the raw material is drawn into fibers. The centrifugal block 13 has various shapes: 1. Rectangular centrifugal block: adopts a cuboid structure, which is simple to process and has a uniform centrifugal force action surface, suitable for medium and low speed conditions; 2. Trapezoidal centrifugal block: the cross-section is a trapezoid with a narrow top and a wide bottom. The center of gravity is lowered, which can enhance the centrifugal force response speed, suitable for high speed scenarios; 3. Arc-shaped centrifugal block: the outer surface is arc-shaped, which reduces frictional resistance when sliding with the inner wall of the fixed ring 12, reducing the risk of jamming; 4. Triangular centrifugal block: the tip points to the centrifugal direction, which reduces air resistance and is suitable for ultra-high speed centrifugation (>3000 rpm) conditions; 5. Streamlined centrifugal block: the aerodynamic curved surface design can reduce turbulent noise during rotation and improve the quietness performance of the equipment.

[0040] Reference Figure 5 To ensure the stability and accuracy of the pull rope 17 during movement, the top of the fixing ring 12 is rotatably connected to multiple guide wheels 15 via a base to guide the pull rope 17. The outer wall of the guide wheels 15 is provided with a limiting groove 16 to limit the pull rope 17 and prevent it from deviating during movement.

[0041] Reference Figure 5In addition, the outer wall of the fixing ring 12 is also fixed with multiple stops 14 by bolts. When the centrifugal roller 8 is stationary, the centrifugal block 13 moves under the action of the pull rope 17, and the stops 14 can be used to limit the centrifugal block 13 to prevent the centrifugal block 13 from moving excessively.

[0042] Reference Figure 1 , Figure 2 and Figure 6 To ensure that the centrifuged fibers are laid out in an orderly manner on the collection tank 27, the present invention also incorporates a reciprocating structure within the sealing structure. This reciprocating structure mainly includes a drive shaft 34 that rotates on one side of the centrifuge chamber 2 via a base, and a sliding rod 28 that slides through the inner wall of one side of the centrifuge chamber 2.

[0043] Reference Figure 6 and Figure 7 A pin 29 is fixed to the top of the sliding rod 28, and a track groove 30 is provided at the bottom of the fixing ring 12. The top of the pin 29 extends into the track groove 30 and slides in cooperation with it. When the fixing ring 12 rotates, the sliding rod 28 can be driven to reciprocate linearly through the cooperation of the pin 29 and the track groove 30. A rack 31 located on one side of the centrifuge box 2 is fixed to one side of the sliding rod 28, and a spur gear 33 is fixed to one side of the centrifuge roller 8 via a frame. A gearbox 32 meshing with the rack 31 is fixed to the input shaft of the spur gear 33. The sliding rod 28 can drive the gearbox 32 to rotate through the meshing between the rack 31 and the gearbox 32. The spur gear 33 is used to adjust the speed of the gearbox 32 and outputs through the drive shaft 34. A rotating disk 35 is fixed to the bottom end of the drive shaft 34, and a pin 36 is fixed to the bottom of the rotating disk 35 off-center. A sliding groove 37 that slides in cooperation with the pin 36 is provided on the top of the collecting plate 25. When the rotating disk 35 drives the pin 36 to revolve, it can drive the collecting plate 25 to reciprocate linearly with the cooperation of the sliding groove 37.

[0044] By setting up a reciprocating structure, the fibers falling from the discharge pipe 18 can be alternately folded and laid on the collection plate 25, thereby achieving uniform collection of fibers.

[0045] Reference Figure 2 and Figure 8 To rapidly cool the spun fibers, this invention incorporates a cooling structure within the centrifuge chamber 2. This cooling structure primarily comprises an air outlet ring 19 and a cooling water ring 22. The air outlet ring 19 is fixed to the inner top wall of the centrifuge chamber 2 via a connecting rod, and an air injection hole 20 is fixedly inserted through the inner top wall of the centrifuge chamber 2. One end of the air injection hole 20 is connected to an external blower, and the other end extends fixedly into the air outlet ring 19 to inject external cold air into the air outlet ring 19. The bottom of the air outlet ring 19 has multiple first through holes 21 for blowing the cold air within the air outlet ring 19 downwards. The cold air not only cools the fibers but also causes them to be discharged downwards.

[0046] Reference Figure 2 and Figure 8 A cooling water ring 22 is fixed to the inner wall of the centrifuge chamber 2, and a liquid injection pipe 24 is fixedly inserted through one side of the centrifuge chamber 2. One end of the liquid injection pipe 24 is connected to an external cooling water source, and the other end is fixedly connected to the cooling water ring 22 for injecting cooling water into the cooling water ring 22. The bottom of the cooling water ring 22 is provided with multiple second through holes 23 for spraying cooling water downwards to further cool the fibers.

[0047] Reference Figure 2 and Figure 6 In addition, a conical discharge ring 43 is fixed inside the centrifuge chamber 2, located below the centrifugal roller 8. The inner wall of the conical discharge ring 43, besides having a basic angle of 30°-60°, can be designed as a corrugated or stepped surface. The corrugated structure extends the contact time between the fiber and the cooling water curtain, and the inner diameter of the conical discharge ring 43 decreases from top to bottom. A cooling water ring 22 is located above the conical discharge ring 43. A discharge pipe 18, penetrating the inner wall of the bottom of the centrifuge chamber 2, is fixed to the bottom of the conical discharge ring 43. The discharge pipe 18 cooperates with the collection tank 27 to collect the fiber.

[0048] As the centrifugal roller 8 rotates to centrifuge and spin fibers, the fibers fall onto the inner wall of the conical discharge ring 43 and are guided towards the center by the inner wall of the conical discharge ring 43 before being discharged through the discharge pipe 18. Simultaneously, cooling water sprayed by the cooling water ring 22 falls onto the conical discharge ring 43 to form a water curtain. Therefore, during the fiber guiding process, the conical discharge ring 43 ensures that the cooling water and fibers are in full contact for water cooling.

[0049] Reference Figure 6 The collection structure mainly includes a collection plate 25 that slides on top of the base 1, and a collection groove 27 for collecting fibers is provided on the top of the collection plate 25. The collection plate 25 moves reciprocally in a linear motion under the drive of the reciprocating structure, so that the fibers can be evenly laid in the collection groove 27.

[0050] Reference Figure 1 , Figure 2 and Figure 9 In order to protect the fibers when the collecting plate 25 reciprocates to collect fibers and prevent external impurities from adhering to the fibers, a protective mesh 26 is slidably fitted on the top of the collecting plate 25, and the protective mesh 26 is slidably sleeved on the outer wall of the discharge pipe 18.

[0051] Reference Figure 2 and Figure 3A transmission pipe 3 is fixedly connected to the top of the centrifugal roller 8, and the top end of the transmission pipe 3 rotates through the inner top wall of the centrifuge chamber 2. A drive motor 5 is fixed to the top of the centrifuge chamber 2 via a frame, and a second bevel gear 6 is fixed to the output shaft of the drive motor 5. A first bevel gear 4 is fixedly sleeved on the outer wall of the transmission pipe 3, and the first bevel gear 4 meshes with the second bevel gear 6. Driven by the drive motor 5, the transmission pipe 3 and the centrifugal roller 8 can rotate, thereby completing the centrifugal fiber forming operation.

[0052] Reference Figure 2 and Figure 3 A U-shaped groove tube 7 is fixed on the top of the centrifuge box 2, and the U-shaped groove tube 7 is connected to the external raw material furnace. A hopper is rotatably connected to the top of the transmission pipe 3, and the hopper is fixed to the top of the centrifuge box 2 by an L-shaped support rod. The hopper and the U-shaped groove tube 7 cooperate to inject molten raw materials into the centrifugal roller 8.

[0053] Reference Figure 2 and Figure 6 In order to protect components such as rack 31, spur gear 33 and gearbox 32, a protective box is fixed to one side of centrifuge 2 by bolts.

[0054] Example 2: Reference Figure 1 , Figure 8 and Figure 9 An improvement upon Embodiment 1 is made as follows: The top of the base 1 is provided with a storage tank 39, and the bottom inner wall of the collection tank 27 is provided with multiple drainage holes 38 for draining cooling water from the collection tank 27 into the storage tank 39. A pump 40 is fixed to one side of the base 1 via a frame. A first flexible hose 41, connected to the storage tank 39, is fixed to the inlet end of the pump 40, and a second flexible hose 42 is fixed to the outlet end of the pump 40, with one end of the second flexible hose 42 fixedly connected to the cooling water ring 22. The pump 40 enables the cooling water to be recycled and reused, avoiding waste.

[0055] A method of using a lightweight mineral wool fiber centrifugal fiber forming device includes the following steps:

[0056] S1. Molten raw material is injected into centrifugal roller 8 through the U-shaped groove pipe 7 and the hopper. Since the nozzle 9 is blocked by the sealing ring 10, the raw material can be stably stored in the centrifugal roller 8, avoiding waste. When centrifugal fiber forming is required, the drive motor 5 drives the transmission pipe 3 and centrifugal roller 8 to rotate through the meshing between the first bevel gear 4 and the second bevel gear 6. As the speed of centrifugal roller 8 gradually increases, when the speed reaches a certain threshold, the centrifugal block 13 moves outward under the action of centrifugal force. The centrifugal block 13 drives the sealing ring 10 to move upward through the pull rope 17, releasing the seal on the nozzle 9. At this time, the raw material in the centrifugal roller 8 is thrown outward through the nozzle 9 under the action of centrifugal force, and then the raw material is drawn into fibers.

[0057] S2. To ensure that the ejected raw material can be quickly formed, an external blower injects cold air into the air outlet ring 19 through the air injection hole 20. The cold air blows downward through the first through hole 21. As the fibers move outward under the action of centrifugal force and the fibers abut against the inner wall of the conical discharge ring 43, the cold air blows downward and can discharge the fibers downward along the inner wall of the conical discharge ring 43. In addition, an external pump 40 injects cooling water into the cooling water ring 22 through the liquid injection pipe 24. The cooling water is sprayed onto the conical discharge ring 43 through the second through hole 23. The inner diameter of the bottom end of the conical discharge ring 43 gradually narrows, so the cooling water forms a water curtain on the inner wall of the conical discharge ring 43. Therefore, when the fibers are discharged downward through the conical discharge ring 43, the cooling water can further cool the fibers.

[0058] S3. Fibers fall onto the collection plate 25 through the discharge pipe 18, completing the collection. To ensure that the collection plate 25 can collect evenly, when the fixed ring 12 rotates, it drives the sliding rod 28 to move back and forth in a straight line through the cooperation of the pin 29 and the track groove 30. The sliding rod 28 drives the spur gear 33 to rotate through the meshing between the rack 31 and the spur gear 33. The gearbox 32 is used to adjust the speed of the spur gear 33 and outputs it through the drive shaft 34, thereby driving the rotating disk 35 to rotate. The rotating disk 35 can drive the collection plate 25 to move back and forth in a straight line through the cooperation of the pin 36 and the sliding groove 37, so that the fibers falling from the discharge pipe 18 can be alternately folded and laid on the collection plate 25.

[0059] S4. In addition, the water flowing downward on the conical discharge ring 43 follows the fiber into the collection tank 27 and enters the storage tank 39 through the leakage hole 38. At this time, the cooling water collected in the storage tank 39 is pumped back into the cooling water ring 22 by the pump 40 for reuse. When it is necessary to remove the fiber in the collection tank 27, the protective net 26 is pushed upward to remove the protective net 26 from covering and protecting the fiber (to prevent external impurities from adhering to the fiber), and the fiber can be removed at this time.

[0060] However, as is well known to those skilled in the art, the working principles and wiring methods of pump 40 and drive motor 5 are commonplace and are all conventional means or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0061] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0062] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

7. A method of using a lightweight mineral wool fiber centrifugal fiber forming device, applied to the lightweight mineral wool fiber centrifugal fiber forming device as described in claim 6, characterized in that, Includes the following steps: S1. Molten raw material injection and centrifugal fiber formation: Molten raw material is injected into the centrifugal roller (8) through the U-shaped groove tube (7). The sealing ring (10) seals the nozzle (9) to store the raw material. When the drive motor (5) is started, it drives the transmission tube (3) and the centrifugal roller (8) to rotate through the meshing of the first bevel gear (4) and the second bevel gear (6). After the speed of the centrifugal roller (8) reaches the threshold, the centrifugal block (13) is moved outward by centrifugal force and drives the sealing ring (10) to move upward through the pull rope (17), releasing the sealing of the nozzle (9) and allowing the raw material to be centrifuged and thrown out through the nozzle (9) to form fibers. S2. Simultaneous operation of dual cooling systems: The blower injects cold air into the air outlet ring (19) through the air injection hole (20). The cold air blows downward through the first through hole (21). As the fibers move outward under the action of centrifugal force and the fibers abut against the inner wall of the conical discharge ring (43), the cold air blows downward and can discharge the fibers downward along the inner wall of the conical discharge ring (43). At the same time, the pump (40) injects cooling water into the cooling water ring (22) through the liquid injection pipe (24). The cooling water is sprayed onto the conical discharge ring (43) through the second through hole (23) to form a water curtain on its inner wall, which further cools the passing fibers. S3. Uniform fiber collection control: Fibers fall into the collection plate (25) through the discharge pipe (18); when the fixed ring (12) rotates, it drives the sliding rod (28) to move back and forth through the pin (29) and the track groove (30). The sliding rod (28) drives the spur gear (33) to rotate through the rack (31) and the spur gear (33). After the gearbox (32) adjusts the speed, it outputs through the drive shaft (34) to drive the rotating disk (35) to rotate. The rotating disk (35) drives the collection plate (25) to move back and forth through the pin (36) and the sliding groove (37), so that the fibers are alternately folded and laid. S4. Cooling water circulation and fiber removal: Water and fibers in the conical discharge ring (43) fall into the collection tank (27), enter the storage tank (39) through the leakage hole (38), and the cooling water is pumped back into the cooling water ring (22) for recycling by the pump (40); push the protective net (26) upward to remove it from covering the fibers and remove the fibers in the collection tank (27).
