The cleaning brush 13 includes a brush handle and bristles. The brush handle is connected to the return spring 11. The return spring 11 has a thrust on the brush handle so that the bristles abut against the inner wall of the heating device 1. The driving motor 4 drives the stirring rod 16 to rotate, so that the bristles can move circumferentially along the heating device 1. The bristles adjust their own conditions according to the obstacle situation during the movement. If the obstacle is large, the return spring 11 is compressed more, and if the obstacle is small, the return spring 11 is compressed less, thereby ensuring that the bristles are in real-time contact with the inner wall of the heating device 1.

Silica sand, limestone, aluminum hydroxide, soda ash and borax are heated in the heating device 1 to form glass fiber liquid, and the glass fiber liquid flows to the leakage plate 7, and the glass fiber liquid is drawn through the leakage holes 9 under the action of gravity.

The heat-insulating layer is made of a foam board and is pasted on the outer wall of the drawing device 2 to ensure that the temperature inside the drawing device 2 does not drop too quickly, so that the glass fiber liquid can be drawn smoothly.

[0043] Preferably, the heating element 6 is a resistance wire or an electric heating tube, which can be arranged circumferentially along the inner wall of the heating device 1, so that the silica sand, limestone, aluminum hydroxide, soda ash and borax in the heating device 1 can be heated to make them into glass fiber liquid.

[0044] In the above embodiment, glass fiber is an inorganic non-metallic material with excellent performance. Glass fiber has many advantages such as heat resistance, corrosion resistance, insulation and high strength. Glass fiber is mainly made of silica sand, limestone, aluminum hydroxide, soda ash and borax. When processing glass fiber, the staff needs to first remove the impurities in silica sand, limestone, aluminum hydroxide, soda ash and borax, and then crush, grind and screen them into qualified powders before placing silica sand, limestone, aluminum hydroxide, soda ash and borax in the heating device 1. The heating element 6 in the heating device 1 heats its internal temperature to a preset temperature to melt the above raw materials to produce glass fiber liquid. During the heating process of silica sand, limestone, aluminum hydroxide, soda ash and borax, the staff starts the stirring component, which is located on one side of the heating device 1 to stir the silica sand, limestone, aluminum hydroxide, soda ash and borax. Aluminum, soda ash and borax are stirred. During the stirring process, the raw materials inside silica sand, limestone, aluminum hydroxide, soda ash and borax can be stirred close to the heating element 6. The stirring component can make each part of silica sand, limestone, aluminum hydroxide, soda ash and borax close to the heating element 6 for heating during the continuous stirring process, so that the raw materials are heated more evenly and the heating efficiency is improved. Moreover, when the stirring component stirs silica sand, limestone, aluminum hydroxide, soda ash and borax, the raw materials inside can be stirred to the outside. The magnetic suction part 5 on the inner wall of the heating device 1 can absorb metal debris in silica sand, limestone, aluminum hydroxide, soda ash and borax in real time, thereby improving the adsorption efficiency of metal debris and avoiding the problem that the metal debris among silica sand, limestone, aluminum hydroxide, soda ash and borax cannot be adsorbed. After the raw materials in the heating device 1 are completely heated to form glass fiber liquid, the staff controls the switch to make the glass fiber liquid in the heating device 1 flow to the drawing device 2. A leakage plate 7 is installed on the upper side of the drawing device 2. The leakage plate 7 is provided with a plurality of leakage holes 9 for drawing the glass fiber liquid. The plurality of leakage holes 9 can simultaneously draw the glass fiber liquid, thereby increasing the flow rate of the glass fiber liquid and avoiding the problem of solidification of the glass fiber liquid due to accumulation for too long. After drawing, the glass fiber liquid can be cooled by a fan, which is convenient for glass fiber molding and heat dissipation. Finally, the staff branches the molded glass fiber into a strand and winds it onto a roller for collection.

[0045] In this embodiment, the heating device 1 can heat silica sand, limestone, aluminum hydroxide, soda ash and borax to a preset temperature to form a glass fiber liquid. During the heating process in the heating device 1, the stirring component can stir the silica sand, limestone, aluminum hydroxide, soda ash and borax, so that each part of them can be stirred close to the heating element 6, thereby improving the heating efficiency; a magnetic suction component 5 is installed on the inner side wall of the heating device 1, and the magnetic suction component 5 can absorb metal debris in silica sand, limestone, aluminum hydroxide, soda ash and borax in real time. During the stirring process of silica sand, limestone, aluminum hydroxide, soda ash and borax, each part of them can be close to the magnetic suction component 5, thereby improving the adsorption efficiency of metal debris and improving the quality of the glass fiber after molding.
