Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber production equipment, in particular to a large package twist-free primary yarn winder. Background Art

[0002] The production process of glass fiber plied untwisted roving includes drawing, forming, winding, inspection and assembly, etc. In the winding production process of glass fiber plied untwisted roving, a single raw silk tube is plied into multiple yarn balls through a winding machine, and finally a finished yarn ball is generated.

[0003] Since each glass fiber manufacturer has different requirements for the winding ratio of yarns of different varieties and different densities (tex) when winding the yarn bobbins, the winding ratio is achieved by the traverse device of the winding machine. Each glass fiber manufacturer has different requirements for the height of the yarn bobbins after winding, but the existing winding machine cannot adjust it due to the structural limitations of the traverse device.

[0004] Glass fiber manufacturers always specify the required bobbin height when purchasing equipment, and purchase winders with different bobbin heights according to their product specifications and production conditions. Once the product specifications change, it is difficult for the existing winders to adapt to the existing specifications, which brings considerable trouble to the manufacturers and greatly affects the manufacturers' market adaptability.

[0005] The prior art winding machine has the following technical problems:

[0006] 1) The winding device, traverse device and shuttle of the existing winding machine share the same power (linkage), and it is quite troublesome to change the winding ratio; basically, a winding machine has a fixed winding ratio and a fixed yarn tube height.

[0007] 2) The reciprocating cycloid mechanism and the grooved drum are difficult to process and require lubrication during operation. It should be noted that glass fiber products are particularly sensitive to oil and will be scrapped once contaminated.

[0008] 3) If the height of the yarn drum needs to be changed, the groove drum needs to be replaced, which is quite troublesome. At the same time, the service life of the groove drum is also a shortcoming.

[0009] 4) The lateral movement device of the winding machine has a complex structure, many parts, high processing difficulty and inconvenient maintenance. Utility Model Content

[0010] In view of this, the purpose of the utility model is to provide a large-package untwisted primary yarn winding machine, in which the winding device, the transverse frame and the shuttle use independent power, and there is no linkage relationship between the three that shares a common power source, which is convenient for separately adjusting the rotation speed of the winding mechanism, the moving speed and distance of the transverse device, and the reciprocating speed of the shuttle; different winding ratios and drum height adjustments are achieved on the same winding machine, which expands the use scope of the winding machine and is convenient for manufacturers to select.
