Description

Technical Field

[0001] The invention relates to the technical field of glass fiber primary twist yarn equipment, in particular to a bending tube correction mold. Background Art

[0002] Cooling fins are placed between the nozzles to absorb the heat radiation from the nozzles and the glass fibers and stabilize the air around the nozzles. It is economical to let as much glass as possible flow out through the nozzles and turn them into glass fibers, but in practice, this is limited by the cooling rate of the glass fibers because the glass fibers are close to each other and radiate heat to each other. Therefore, forming a stable glass fiber root is very necessary for effective wire drawing.

[0003] The temperature range for the stability of the fiber root, the drawing speed, the viscosity and the surface tension is very narrow. If the temperature is too low (the viscosity is too high), the drawing diameter will decrease. If the tension is greater than the tensile strength, it will cause flying fibers. If the temperature is too high (the viscosity is too low), the fiber root is unstable and the fiber will break. In order to keep the fiber root stable, a cooling plate is required.

[0004] The cooler is welded on a copper bracket and fixed with pliers. The cooler allows cooling water to enter its water bag through a bend pipe to achieve heat exchange. The cooling fins are arranged horizontally under the leak plate, so the bend pipe needs to be bent 100°-120° to connect the cloth-reinforced hose to achieve heat exchange of cooling water.

[0005] The bending angle of the bent pipe may change due to the extrusion during transportation, or the bending angle made by the manufacturer does not meet the use requirements, so the angle needs to be corrected before use. Manual correction is time-consuming and labor-intensive, and cannot guarantee the uniformity of the bending process. Summary of the invention

[0033] A first bending wheel 41 is mounted on the rotating wheel 3 , and the first bending wheel 41 is coaxially arranged with the rotating wheel 3 .

[0034] The limiting mechanism comprises a supporting frame 21 and a limiting frame, and the limiting frame is installed on the base 1 through the supporting frame 21 .

[0035] The limiting frame includes a transverse plate 22 and a limiting plate 23. The transverse plate 22 is horizontally arranged on the support frame 21, and the limiting plate 23 is vertically installed on the left edge of the transverse plate 22. The limiting plate 23 prevents the bent pipe 8 from moving away from the limiting frame.

[0036] like Figure 1-Figure 3 As shown, a connecting plate 51 is fixedly mounted on the outer circumference of the rotating wheel 3 , and a vertically arranged supporting rod 52 is mounted on the connecting plate 51 .
