Description

Technical Field

[0001] The invention relates to the technical field of glass fiber reinforced plastic production, and in particular to a conveying device for glass fibers. Background Art

[0002] The scientific name of FRP is fiber reinforced plastic, a composite material with synthetic resin as the matrix material. Fiber reinforced composite materials are composed of reinforcing fibers and a matrix. The diameter of the fiber (or whisker) is very small, generally below 10μm, with fewer and smaller defects, and a fracture strain of about 30 thousandths. It is a brittle material that is easily damaged, broken and corroded. Compared with the fiber, the matrix has much lower strength and modulus, but it can withstand large strains, often has viscoelasticity and elastoplasticity, and is a tough material;

[0003] In the production and processing of glass fiber, the production process of FRP is that the wire press presses the heated raw materials into glass fibers. The initial shape of the glass fibers pressed out of the raw materials is not very stable. During the processing, water is needed to cool the glass fiber liquid in the initial state to solidify the extruded glass fiber liquid. The purpose of processing cooling is to reduce the fluidity of the initial glass fiber liquid. The existing glass fiber liquid cooling method is to spray water on the output position of the wire press. Since the glass fiber liquid just comes out of the wire press, the water cannot cover the glass fiber just coming out, and the glass fiber liquid just formed is not very stable, and the glass fiber liquid will flow. Therefore, the spraying method will cause the formed glass fibers to be of different thicknesses. Summary of the invention

[0004] The present invention proposes a conveying device for glass fibers. In the production and processing of glass fibers, a wire press presses heated raw materials into glass fibers. The shape of the newly extruded glass fibers is not very stable, and they need to be aligned and cooled to solidify the extruded liquid and reduce the fluidity of the molding liquid. The existing cooling method is to spray the output position. The liquid that has just come out of the wire press cannot cover the glass fibers. The glass liquid may flow for the newly molded glass fibers, resulting in different thicknesses of the molded glass fibers.

The inner diameter of the input end of the input pipe 206 is larger than the inner diameter of the output end, and the water pressure is easy to adjust.

[0032] like Figure 1 to Figure 7 As shown, it also includes a fiber pulling device 3 arranged in the middle of the equipment frame 1, and the fiber pulling device 3 includes two sets of driving bearings arranged in the middle end of the equipment frame 1 and two sets of vertical sliding rod groups 301 fixed in the vertical direction of the equipment frame 1 and two sets of horizontal sliding rod groups 302 arranged in the horizontal direction of the equipment frame 1.

The purpose is to change the physical properties of the fiber yarn, enhance the strength and tensile properties of the fiber yarn, and make it have a certain elasticity, so that the glass fiber passes through the fiber passing block 309, drives the fiber pulling motor, and the fiber pulling motor drives the two groups of rotating rods 305 to rotate through the transmission wheel, and the eccentric wheel 306 at the rotating rod 305 rotates, and the eccentric wheel 306 drives the lever 307 to rotate eccentrically, and the lever 307 moves the lever block 304, so that the lever block 304 moves horizontally on the track of the horizontal sliding rod group 302, and at the same time moves vertically on the track of the vertical crossbar group, and the fiber passing block 309 stretches the glass fiber, and the glass fiber is stretched horizontally and vertically.

[0035] like Figure 6~Figure 7As shown, a swing plate 310 is arranged between the two fixed plates 308, and a plurality of groups of swing fiber blocks 312 are arranged on the swing plate 310. The swing fiber blocks 312 are penetrated with fiber passing holes, and end blocks 311 are fixed at both ends of the swing plate 310. One end of the end block 311 is rotatably connected to the equipment frame 1 through a bearing, and two groups of cylinders 313 are arranged in the middle position of the equipment frame 1. The output end of the cylinder 313 is hinged to the other end of the end block 311 through a hinge shaft, and a sliding groove is opened at the other end of the end block 311. The hinge shaft slides and is hinged to the inner wall of the sliding groove of the end block 311. The swing fiber block 312 is used to pass glass fiber and adjust the angle in the process of stretching the fiber up and down.

[0038] The winding wheel 5 is used for winding the glass fiber so that the glass fiber is stressed at two positions.

[0039] Furthermore, it also includes multiple groups of fiber advancing devices 6, the fiber advancing devices 6 include a slide rail and several groups of conductor blocks 601, the slide rail is slidably connected to a slider, the slide rail and the slider are fixed by nuts, the conductor block 601 is fixed on the top of the slider, a wheel mounting groove is opened on the surface of the conductor block 601, the inner wall of the wheel mounting groove is rotatably connected to a conductor wheel 602 through two groups of wheel bearing seats, the fiber advancing device 6 is used to gather multiple groups of fibers into one group, and the conductor block 601 can adjust the spacing and is fixed by nuts.

[0040] like Figure 8~Figure 9 As shown, the farther away the fiber feeding device 6 is from the equipment frame 1, the smaller the spacing between the conductor blocks 601 on the fiber feeding device 6 is, and the fiber feeding device gradually gathers multiple groups of fibers into one place. The fibers gathered into one place are passed through a gathering pulley set arranged on a slide rail, and then wound onto a glass fiber reel.

[0041] When the glass fiber needs to be rolled, the wire is firstly led before winding. The cooling pipe 202 is used to dock with the wire pressing port of the glass fiber wire pressing machine. The cooling pipe 202 can be moved by applying force to move the rod 204. When no force is applied, the spring piece 203 presses the cooling pipe 202 to fix the cooling pipe 202. When the glass fiber needs to be wound, the wire is firstly led to lead a certain length of fiber from the glass fiber wire pressing machine so that this part of the fiber passes through the cooling pipe 202.

[0043] When the glass fiber passes through the cooling pipe 202, the fast water flow can quickly fill the interior of the cooling pipe 202, and make the water flow on the inner wall of the cooling liquid pipe 205 in a jet shape, so that the glass liquid pressed out from the wire press is instantly cooled into glass fiber, and then the glass fiber is stretched and processed by the fiber pulling device 3, driving the fiber pulling motor, and the fiber pulling motor drives the two groups of rotating rods 305 to rotate through the transmission wheel, and the eccentric wheel 306 at the rotating rod 305 rotates, and the eccentric wheel 306 drives the lever 307 to rotate eccentrically, and the lever 307 pulls the lever block 304, so that the lever block 304 moves laterally along the track of the horizontal slide bar group 302, and at the same time moves vertically along the track of the vertical cross bar group, and the fiber passes through the block 309 to stretch the glass fiber, and the glass fiber is stretched horizontally and vertically. The combined horizontal and vertical stretching makes the fiber stretch around a curvature. Compared with stretching in one direction, the multi-curvature stretching is uniformly stressed, and at the same time, the swing fiber block 312 can change the up and down stretching angles, and change the stress on the fiber when it is stretched;

[0044] The fiber is pulled and swung to achieve an ideal stretching ratio. The purpose of pulling and swaying is to change the physical properties of the fiber, enhance the strength and tensile properties of the fiber, and make it have a certain elasticity. The stretched glass fiber is led out through the lead-out block 4, and then led out to the winding wheel 5. The winding wheel 5 separates the upper and lower glass fibers by force until at most groups of fiber advancement devices 6 are gathered.
