Description

Technical Field

[0001] The utility model belongs to the technical field of yarn length measuring equipment, and more specifically, particularly relates to a length measuring device based on glass fiber yarn. Background Art

[0002] Glass fiber yarn is an inorganic non-metallic material with excellent performance. It uses glass balls or waste glass as raw materials and is manufactured through high-temperature melting, drawing, winding, weaving and other processes. Glass fiber yarn has many advantages, including good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. However, its disadvantages are brittleness and poor wear resistance. When measuring the length of glass fiber yarn, a yarn length gauge is needed. The yarn is wound into a set number of turns, and the worker calculates the length by multiplying the number of turns by the turn length. However, the current yarn length gauges are still found to have some disadvantages during use:

[0003] First, when measuring the length of glass fiber yarn using a yarn length gauge, the yarn bobbin is prone to movement, which in turn affects the winding of the length gauge and easily affects the measurement results.

[0004] Second, after the yarn length is measured, it is difficult to remove it due to the tensioning force, which not only makes the operation difficult but also easily causes wear of the yarn. Utility Model Content

[0005] In order to solve the above technical problems, the embodiments of the present disclosure relate to a length measuring device based on glass fiber yarn, so as to solve the problem that the yarn bobbin is prone to movement during winding and the yarn is difficult to be removed due to the tensioning force after the length measurement is completed. By setting the tightening mechanism, the yarn bobbin can be tightened and fixed to ensure that the yarn bobbin does not move during winding, improve the stability during winding, and avoid affecting the measurement results. By setting the self-adjusting structure of tension, the tightness of the winding rod can be freely adjusted, which is easy to operate, convenient for taking out the yarn, and reduces the wear on the yarn.

[0006] The utility model is based on the glass fiber yarn length measuring device, which is achieved by the following specific technical means:

[0007] In a first aspect of the present disclosure, a length measuring device based on glass fiber yarn is provided, specifically comprising a fixed base;

[0008] The top side of the fixed base is fixedly connected to a fixed vertical plate, and a control switch is also provided on the top of the fixed base, and a tightening mechanism is provided inside the fixed base. The tightening mechanism includes a moving cavity, a two-way screw rod, a guide rod, a turning handle, a moving belt block, a threaded hole, a guide sliding hole and a tightening column. The fixed base is provided with a moving cavity, and a two-way screw rod is rotatably installed inside the moving cavity. A guide rod is provided on one side of the two-way screw rod, and one end of the two-way screw rod passes through the fixed base and is fixedly connected to the turning handle on the outside. Two groups of moving belt blocks are provided inside the moving cavity, and threaded holes and guide sliding holes are respectively provided on the moving belt blocks. The threaded holes are rotatably engaged with the two-way screw rods, and the top of the moving belt block is fixedly connected with a tightening column.

Then, the handle is rotated to drive the bidirectional screw to rotate. The bidirectional screw is engaged with the threaded hole on the movable belt block. However, the movable belt block is guided by the upper limit of the guide rod through the guide slide hole, so that the bidirectional screw drives the two sets of movable belt blocks to move in opposite directions. The movable belt block drives the tightening column to tighten the yarn bobbin, ensuring that the yarn bobbin will not move during winding, improving the stability during winding, and avoiding affecting the measurement results.

[0016] The present application sets up a self-adjusting structure for tension and elasticity, and pulls the movable ring to drive the connecting pin out of the first perforation and the second perforation, thereby adjusting the position of the adjusting strip in the adjusting groove, so as to reduce the tensioning force of the winding rod on the yarn, and then it can be easily removed, which is convenient to operate and reduces wear on the yarn.
