[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Liquid glass can be introduced into the upper inner cylinder through the concave surface of the feed port, a part of the liquid glass can be received through the recess on the upper guide chamber inside the upper inner cylinder, and can be introduced into the lower inner cylinder through the downflow hole, and the upper inner cylinder and the lower inner cylinder can be driven to rotate by the rotating shaft and the rotating cylinder through the servo motor, so that the liquid glass can be thrown out from the through hole by the centrifugal force during rotation to form slender glass fibers, and the liquid glass can be guided to the inner edges of the upper inner cylinder and the lower inner cylinder through the top arc surface of the upper guide chamber and the lower guide chamber, so that when centrifugal spinning is performed, the liquid glass can be more concentrated at the through hole, so that the liquid glass can contact the through hole faster, and at the same time, the possibility of liquid glass interruption can be reduced, so that when centrifugal spinning is performed, the liquid glass will not be unstable due to interruption, so that the fiber output process can be more stable and efficient.

[0016] 2. During the centrifugal spinning process, the servo motor can drive the shaft to rotate, the upper bevel gear on the outer periphery of the shaft can drive the transmission bevel gear to rotate, and the lower bevel gear can be used to drive the drum to rotate through the transmission bevel gear, so that the shaft and the drum can rotate in the opposite direction, and the shaft and the drum can drive the upper inner drum and the lower inner drum to rotate in the opposite direction, so that the glass fibers swung out of the upper inner drum and the lower inner drum can contact in a staggered manner, forming a more stable cross structure, so that the subsequent glass fibers can have higher strength and bondability when bonded and stacked, so that the fibers can be combined more closely, and the formed glass wool will not loosen easily.

[0017] 3. When stacking the fibers, the reduction motor can drive the driving gear to rotate, and the driving gear can use the fixed gear ring meshing with the driving gear to drive the outer cylinder to rotate. The fixed ring and the deflection plate inside the outer cylinder can form an inward-swirl airflow during rotation, thereby restraining the ejected glass fibers and preventing them from adhering to the inner wall of the outer cylinder. At the same time, the rotating shaft can drive the fixed rod and the guide frame at the bottom to rotate, thereby forming an outward-swirl airflow, thereby supporting the ejected glass fibers. The two cyclones cooperate to form an annular vortex, and the wind can assist in cooling the glass fibers, which is beneficial to the rapid molding of the glass fibers. At the same time, the annular vortex can drive the ejected glass fibers to rotate, so that the double-layer glass fibers after interlacing can be twisted, further improving the strength of the glass wool after subsequent stacking, which is beneficial to practical use.

[0018] 4. The stepper motor can drive the gear column to rotate, and the stepper motor can drive the rotating ring to rotate through the meshing tooth segments. When the rotating ring rotates, the lower gear ring at the bottom will drive the driven gear to rotate synchronously. The driven gear can use the rotating rod to drive the deflection plate to deflect.

The two cyclones cooperate with each other to form an annular vortex. The wind can assist in cooling the glass fiber, which is beneficial to the rapid molding of the glass fiber. At the same time, the annular vortex can drive the thrown glass fiber to rotate, so that the double-layer glass fiber after interlacing can be twisted, further improving the strength of the glass wool after subsequent stacking, which is beneficial to practical use.

[0042] Furthermore, in a specific implementation, when the microfiber glass wool is produced by centrifugal method, the following multiple operation steps are included:

[0043] S1. Raw material preparation: Select appropriate glass raw materials, quartz sand, limestone, and soda ash, wash them, and crush them into pieces with a diameter of less than 30 mm. Then use a mixer to mix them to ensure the uniformity of the raw materials and form a mixture. People can add some recycled waste glass to the mixture to reduce the input cost of raw materials. The recycled waste glass is also washed, crushed and mixed before adding;

[0044] S2, material melting: the mixed material is put into a high-temperature melting furnace for high-temperature melting to convert it into liquid glass. The temperature of the high-temperature melting furnace is maintained at 1600° C. The liquid glass is introduced into the feed port 102 through the feed pipe 105. The liquid glass can be introduced into the upper inner cylinder 141 through the inner concave surface of the feed port 102;

[0045] S3, fiberization: the molten liquid glass liquid can receive a part of the liquid glass liquid through the notch 146 on the upper guide chamber 147 inside the upper inner cylinder 141, and can be introduced into the lower inner cylinder 143 at the lower part through the downflow hole 145. The servo motor 103 can use the rotating shaft 104 and the rotating cylinder 118 to drive the upper inner cylinder 141 and the lower inner cylinder 143 to rotate, so that the liquid glass liquid can be thrown out from the through hole 142 by the centrifugal force during rotation to form slender glass fibers. In this process, the cold air in the connected cold air source can be extracted by 128 through the work of 129, and then the thrown glass fiber filaments can be quickly cooled through the air outlet to form solid fiber filaments;

[0046] S4, applying the binder: during or after the glass fiber is formed, the binder stored in the fixed bin 133 can be extracted through the spraying turntable 132, and the binder can be rotated and sprayed toward the ejected glass fibers to apply the binder to the surface thereof. The function of the binder is to bond the glass fibers together to form a glass wool product with a certain strength and stability. The binder can be selected from one of phenolic resin, epoxy resin and acrylate;

[0047] S5, fiber stacking: a reciprocating stacking platform is arranged at the bottom discharge port of the centrifugal fiber spinning machine 1, and the glass fibers discharged from the centrifugal fiber spinning machine 1 can be received by the reciprocating movement of the stacking platform. The glass fibers can be continuously reciprocated and stacked by the reciprocating movement of the stacking platform. In actual use, multiple centrifugal fiber spinning machines 1 can be arranged in parallel, so that different types of glass fibers can be produced at the same time. The glass fiber types include alkali-free glass fibers, high modulus glass fibers and alkali-resistant glass fibers. When stacking glass fibers, multiple glass fibers can be compositely stacked by the reciprocating stacking platform, so that directional stacking and composite stacking can be achieved at the same time;

[0048] S6. Glass wool molding: When the stacking amount reaches a predetermined thickness, the glass fiber pile with adhesive applied is introduced into a molding device through a conveyor belt. The molding device, which can be one of a mold, a press or a winder, is molded into a desired shape and size. Common glass wool products include felt, board, and tube.

[0049] Working principle:

[0050] In actual use, people can introduce liquid glass into the feed port 102 through the feed pipe 105, and can introduce the liquid glass into the upper inner cylinder 141 through the inner concave surface of the feed port 102. A portion of the liquid glass can be received through the recess 146 on the upper guide chamber 147 inside the upper inner cylinder 141, and can be introduced into the lower inner cylinder 143 at the bottom through the downflow hole 145. The servo motor 103 can use the rotating shaft 104 and the rotating cylinder 118 to drive the upper inner cylinder 141 and the lower inner cylinder 143 to rotate, so that the liquid glass can be thrown out from the through hole 142 by the centrifugal force during rotation to form slender glass fibers. The liquid glass can be thrown out through the top arc surface of the upper guide chamber 147 and the lower guide chamber 144. The fiber 140 is guided to the inner edge of the upper inner cylinder 141 and the lower inner cylinder 143, so that when the centrifugal fiber is spun, the liquid glass liquid can be more concentrated at the through hole 142, so that the liquid glass liquid can contact the through hole 142 faster, and at the same time, the possibility of the liquid glass liquid being cut off can be reduced, so that when the centrifugal fiber is spun, the liquid glass liquid will not be unstable due to the cut off, so that the fiber-pulling process can be more stable and efficient. In the process of centrifugal fiber spinning, the servo motor 103 can drive the rotating shaft 104 to rotate, and the upper bevel gear 115 on the outer periphery of the rotating shaft 104 can drive the transmission bevel gear 117 to rotate, and the lower bevel gear 119 can be used to drive the rotating drum 118 to rotate through the transmission bevel gear 117, so that The rotating shaft 104 and the rotating drum 118 are rotated in opposite directions, and the upper inner drum 141 and the lower inner drum 143 can be driven to rotate in opposite directions through the rotating shaft 104 and the rotating drum 118, so that the glass fibers thrown out of the upper inner drum 141 and the lower inner drum 143 can be in contact with each other in a staggered manner, forming a cross structure with stronger stability, so that the subsequent glass fibers can have higher strength and bondability during bonding and stacking, so that the fibers can be more tightly combined, and the formed glass wool will not be easily loosened. When the fiber is stacked, the driving gear 130 can be driven to rotate through the reduction motor 106, and the outer drum 114 can be driven to rotate by the fixed gear ring 109 meshing with the driving gear 130, and the inner part of the outer drum 114 can be driven to rotate by the fixed gear ring 109 meshing with the driving gear 130. The fixing ring 121 and the deflection plate 127 can form an inwardly rotating airflow when rotating, so as to restrain the thrown glass fibers and prevent the glass fibers from adhering to the inner wall of the outer cylinder 114. At the same time, the fixing rod 125 and the guide frame 126 at the bottom can be driven to rotate through the rotating shaft 104, so as to form an outwardly rotating airflow, so as to support the thrown glass fibers. The two cyclones cooperate to form an annular vortex, and the wind can assist in cooling the glass fibers, which is beneficial to the rapid molding of the glass fibers. At the same time, the annular vortex can drive the thrown glass fibers to rotate, so that the double-layer glass fibers after interlacing can be twisted, further improving the strength of the glass wool after subsequent stacking, which is beneficial to practical use.The stepper motor 135 can drive the tooth column 136 to rotate, and the stepper motor 135 can drive the rotating ring 134 to rotate through the meshing tooth segments 138. When the rotating ring 134 rotates, the lower tooth ring 139 at the bottom will drive the driven gear 137 to rotate synchronously. The driven gear 137 can use the rotating rod 140 to drive the deflection plate 127 to deflect. By adjusting the deflection angle of the deflection plate 127, the influence range and airflow intensity of the inward rotating airflow can be adjusted, so as to adapt to different centrifugal speeds and fiber output amounts during fiber throwing, which is beneficial to the production of glass wool. During fiber stacking, when the outer cylinder 114 rotates, the outer gear ring 123 on the outer periphery of the outer cylinder 114 can drive the inner gear ring 122 to rotate by means of the meshing transmission gear 124, and the inner gear ring 122 can drive the rotating frame 113 to rotate as a whole, and the guide vanes 112 obliquely arranged on the rotating frame 113 can form a restrained cyclone to further restrain the glass fiber, thereby preventing the glass fiber from being scattered by centrifugal force during fiber stacking, which is beneficial to fully utilizing the glass fiber, and at the same time can make the formed glass wool more dense, which is beneficial to improving the actual performance of the finished glass wool.
