Abstract
Description
Technical Field

[0002] Glass fiber tape is made of high-strength high-temperature resistant glass fiber and processed by special technology. It has the characteristics of high temperature resistance, thermal insulation, insulation, fire retardant, corrosion resistance, aging resistance, weather resistance, high strength, smooth appearance, etc. At present, when producing glass fiber tape, it is usually necessary to place multiple glass fiber rolls directly on multiple shafts, and then pull out multiple glass fiber strands at the same time for weaving. The glass fiber strands are usually wound on a winding wheel. When producing glass fiber tape in this way, friction will occur between the winding wheel and the shaft. When the internal wear of the winding wheel is large, the friction between the winding wheel and the shaft will increase, affecting the pulling speed of the glass fiber strands. There may also be a gap between the winding wheel and the shaft. When pulling out the glass fiber strands, the shaking of the winding wheel will cause the glass fiber strands to be insufficiently tensioned, and then twisted wires will appear. Utility Model Content

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.
[0021] The present application embodiment provides a glass fiber yarn fixing tube, such as Figure 1-Figure 4 As shown, it includes outer cylinder 1, inner cylinder 3, push ring 4, etc.
[0022] Specifically, the outer cylinder 1 is provided with a plurality of groups of through grooves 101 along the axial direction, and a paddle 2 is provided between adjacent through grooves 101 in each group of through grooves 101, and the paddle 2 is hinged to the outer side of the outer cylinder 1 through a hinge seat 201; the inner cylinder 3 is arranged in the outer cylinder 1, and the number of push rings 4 matches the number of groups of through grooves 101, and they are all sleeved outside the inner cylinder 3, and the push rings 4 are provided with levers 401 matching the number of each group of through grooves 101 in a circumferential array on the circumference side, and the levers 401 are all arranged in the corresponding through grooves 101, and a fixing ring 301 is provided at intervals below a push ring 4 The inner tube 3 is rotatably connected to the outer tube 1 through the fixing ring 301. The top of the fixing ring 301 is connected to one end of a torsion spring 302. The other end of the torsion spring 302 is connected to a push ring 4. When the lever 401 is at one end of the through slot 101, the torsion spring 302 is in a natural state, and the lever 401 moves toward the end of the paddle 2 connected to the hinge seat 201. When the lever 401 is at the other end of the through slot 101, the torsion spring 302 is in a tightened state, and the lever 401 moves toward the end of the paddle 2 away from the corresponding hinge seat 201.
[0023] In actual use, the outer cylinder 1 can be rotatably connected to a fixed frame. For details, refer to Figure 1 , a ring connected to the bottom of the outer cylinder 1 can be rotated and rotated, and then the inner cylinder 3 is rotated to make the lever 401 at the other end of the through groove 101. At this time, the lever 401 moves toward the end of the paddle 2 away from the corresponding hinge seat 201, so that the paddle 2 is retracted inward, and the winding wheel wound with the glass fiber can be inserted into the outer tube 1, and then the inner cylinder 3 is loosened, the torsion spring 302 will drive the push ring 4 and the inner cylinder 3 to reset, and at this time, the lever 401 moves toward the end of the paddle 2 connected to the hinge seat 201, pushing the paddle 2 outward and abutting against the inner wall of the winding wheel, thereby fixing the winding wheel.
[0024] For details, see Figure 3 , a slide bar 7 is slidably connected inside the inner cylinder 3, the top of the slide bar 7 passes through the top of the inner cylinder 3 and is connected to a limit rod 701, and a limit column 702 is provided on the top of the outer cylinder 1, and the limit rod 701 abuts against the limit column 702. When the winding wheel needs to be put in or taken out, the slide bar 7 is pulled upward to make the limit rod 701 reach the top of the limit column 702, and then the inner cylinder 3 is controlled to rotate by the slide bar 7 to make the lever 401 move toward the end of the paddle 2 connected to the hinge seat 201, so that the paddle 2 is no longer subjected to the outward thrust, and then the slide bar 7 is pushed downward to make the limit rod 701 on one side of the limit column 702, which can prevent the push ring 4 from rotating due to the torsion of the torsion spring 302, and facilitate the insertion or removal of the winding wheel.
[0025] Preferably, see Figure 3The limiting rods 701 are a pair, symmetrically arranged around the sliding rod 7, and the limiting posts 702 are two, both arranged at the top of the outer tube 1. When the lever 401 is at the other end of the through slot 101, the limiting rods 701 are respectively against the two limiting posts 702. By providing a pair of limiting rods 701, it is convenient to pull the sliding rod 7 upwards, and at the same time, the two limiting posts 702 limit the rotation of the limiting rods 701, so that the stability of the push ring 4 can be improved.
[0026] For details, see Figure 1 The top of the slide rod 7 is threadedly connected to a limit plate 8. More specifically, the diameter of the limit plate 8 can be set to be larger than the inner diameter of the winding wheel to be placed in, so as to prevent the glass fiber coil from sliding out of the outer cylinder 1 along the axial direction of the outer cylinder 1.
[0027] Preferably, see Figure 4 The inner side of the paddle 2 is connected to one end of a spring 6, and the other end of the spring 6 is connected to the outer side of the outer tube 1 or the hinge seat 201. When the lever 401 is at one end of the through slot 101, the spring 6 is in a stretched state. When the lever 401 is at the other end of the through slot 101, the spring 6 is in a natural state. When the lever 401 moves toward the end of the paddle 2 away from the corresponding hinge seat 201, the spring 6 will drive the paddle 2 to rotate inward automatically, and there is no need to manually push the paddle 2 inward to put the winding wheel in.
