[0002] Linen yarn has excellent properties such as high strength, good moisture absorption, good air permeability, and is not easy to pilling. It is also not prone to static electricity and is commonly used in the production of clothing and household items.

[0003] The Chinese invention patent with authorization announcement number CN114275629B: A textile yarn fixed-length winding and rotating machine discloses that the fixed-length winding of the textile yarn is completed by cooperating with a bottom plate, a side plate, a fixed-length device, a guiding device, a winding device and a cutting device; this scheme has the beneficial effect of accurate winding length, but after the winding is completed, the interval time for the next round of winding operation is long, and the winding efficiency is low.

[0004] The Chinese invention patent with authorization announcement number CN112027784B: A textile yarn winding device discloses a technical solution of the present invention that can effectively increase the efficiency of disassembly and assembly of the winding roller by quickly fixing the winding roller after the elastic ring expands. However, this solution also has the technical problem of lengthening the winding interval due to replacement of the yarn tube.

[0005] The Chinese utility model patent with authorization announcement number CN221318705U: A uniform winding device for yarn to prevent pulling and breaking, discloses that by setting a fixing mechanism, after the winding roller has wound up a roll of yarn, the transmission shaft of the fixing mechanism is detached from the winding roller, which can achieve the purpose of disassembling the winding roller, and is conducive to quickly disassembling the winding roller from the inside of the winding device, thereby improving the winding efficiency of the yarn. This solution also has the technical problem of long winding intervals due to replacement of the yarn tube, and it is necessary to frequently observe whether the yarn has been wound up.

[0006] The technical solutions of the above-mentioned invention patents are unable to comprehensively improve the winding efficiency of the yarn, so the field is in urgent need of a linen yarn bobbin alternating winding device to solve the above-mentioned problems. Summary of the invention

[0007] The purpose of the present invention is to provide a linen yarn bobbin alternate winding device to solve the technical problem of low linen yarn winding efficiency in the prior art.

The automated telescopic rod can control the height of the bell-mouthed wire component, and further control the winding height of the yarn on the yarn drum.

[0011] As a preferred solution, a blade is fixedly connected to the side wall of the bell-mouth wire component close to the sliding direction of the slider, and the blade edge protrudes from the side wall of the bell-mouth wire component. After the finished wire coil is wound up, during the process of the finished wire coil rotating around the motor drive shaft of the first motor transmission mechanism as the axis, the unbroken yarn can form an acute angle bend at the blade, and then the yarn is cut by the blade, thereby realizing the function of automatic cutting after the finished wire coil is produced, and adopts a mechanical cutting method with a high fault tolerance rate.

[0019] After the winding is completed and the finished coil is produced, the solution can automatically replace the empty yarn drum to the winding position. It only needs to manually replace the finished coil that is not in the winding position with the empty yarn drum, so that the winding and replacement of the yarn drum can be carried out at the same time, which greatly reduces the time interval for replacing the yarn drum and improves the winding efficiency. This solution can automatically cut the tail wire of the finished wire coil by mechanical operation, which indirectly improves the winding efficiency and has a high success rate of cutting the tail wire; The hooking groove designed in this scheme can quickly wind the yarn on the yarn tube by hooking the yarn end, thereby further improving the winding efficiency.
