An oiling box cover of an oiling device for glass fiber manufacturing

Abstract

The invention relates an oiling box cover of an oiling device for fiberglass manufacture. The oiling box cover comprises a left inclined clamping slot and a right inclined clamping slot, an upper plate and a lower plate are arranged between the two clamping slots, the front side edge of the lower plate is located on the back of the front side edge of the upper plate, and downward inclined plates are arranged at the front ends of the clamping slots. Protecting plates are movably connected to the clamping slots through connecting rods, and a blocking rod is arranged on each connecting rod. Compared with the prior art, the oiling box cover has the advantages that due to the double-layer plates which are installed in a manner of one top-one bottom, one front-one back and high front-low back, rubber of the oiling device is free of water drops, and wind ripples at the rubber due to air flow are relieved greatly; the oiling box cover is less in material consumption, long in service time, high in safety coefficient and less prone to causing scratches to operators; cleaning is facilitated, and a good environment is provided to a tow placement area.

Description

technical field [0001] The invention relates to an oiling box cover of an oiling device for glass fiber manufacture. Background technique [0002] Glass fiber is an inorganic non-metallic material with excellent performance. There are many kinds. The advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but the disadvantages are brittleness and poor wear resistance. It is made of glass balls or waste glass through high-temperature melting, wire drawing, winding, weaving and other processes. The diameter of its single filament is several microns to more than 20 microns, which is equivalent to a hair. 1 / 20-1 / 5 of that, each bundle of fiber precursors consists of hundreds or even thousands of monofilaments. [0003] Glass fiber is made by taking different types of mineral raw materials, melting at high temperature inside the tank kiln to form glass liquid, and then forming into platinum leak plate, and forming the roots...

Problems solved by technology

After the sizing agent in the prior art enters the oiling box through the pipeline, the motor drives the roller to rotate, so that the sizing agent is evenly taken away by the rubber belt on the roller and evenly coated on the tow to achieve the oiling effect. The oil box cover can block the water spray; if figure 1 As shown, the oiling device is generally composed of a motor, oiling box 1, oiling box cover 2, oiling roller 3, motor connection block, rubber 4, and oil inlet and return pipes; After 1, the motor drives the roller 3 to rotate, so that the sizing agent is evenly taken away by the rubber 4 on the roller and evenly coated on the tow to achieve the oiling effect; however, when the oiled box cover in the prior art is used There are the following problems: 1. The front end of the box cover is a downward arc 7, the contact surface is large, and the spray water in the forming area brought by the tow is easily attached to the arc surface figure 1 On A, water droplets are generated, and water droplets often drip into the oiling box, which will cause the dilution of the sizing agent and easily cause the quality of the original silk to decline; 2. The front end of the oiling box cover is far away from the micelles, about 2cm, figure 1 At B, when the high-speed rotating wire drawing machine is running, the tow quickly drives down the strong airflow around the bushing plate. When the tow passes through the rubber, the airflow at the rubber is too large, and the sizing cannot be better taken away by the rubber, which seriously affects Tow oiling; 3. A rubber protective plate with ribs 6 is hinged on the oiling box cover 2. When the oiling device is in normal use, the protective plate is generally turned backwards and placed on the oiling box cover (such as figure 1 As shown), when no oil is applied, the protection plate is turned forward to protect the rubber. However, when the protection plate is turned backwards and placed on the oiled cover, there are often water droplets due to the blocking of the ribs. When turned forward, the water droplets It is also easy to fall into the box cover to dilute the wetting agent; 4. The oiling roller 3 will have different types of support blocks to replace, so the front and rear distances will change. Since the oiling box cover cannot move forward and backward, it cannot play a good role. The effect of blocking water spray;
