Description

Technical Field

[0001] The invention relates to the technical field of yarn winding, and in particular to a yarn winding machine based on self-starting limited winding by the deadweight of a reel. Background Art

[0002] In the textile industry, yarn winding is a crucial link. After the yarn is output from the production equipment, it needs to be neatly and efficiently wound up for subsequent storage, transportation and further processing. The traditional yarn winding method often has some limitations, which has prompted the development of new yarn winding machines. Early yarn winding mostly relied on simple mechanical structures, such as manual or semi-automatic winding devices. These devices require frequent manual intervention during the winding process, which is not only inefficient, but also has uneven winding quality. For example, manual operation is difficult to ensure the uniform distribution of yarn on the drum, which may cause too much yarn accumulation on one side of the drum and too little on the other side, affecting the balance of the drum and the use of the yarn. In addition, when using traditional winding equipment for drums with different inner diameters, different accessories often need to be replaced or complex adjustments need to be made, which greatly reduces production efficiency.

[0003] With the development of the textile industry, the requirements for the speed, quality and automation of yarn winding are getting higher and higher. Automated yarn winding machines have emerged. They have improved the winding efficiency and quality to a certain extent. However, the existing automated winding machines still need to be improved in some key links. On the one hand, in the startup link, many winding machines need to be started manually or according to the preset program. They cannot be intelligently triggered according to the actual situation of the reel. This may lead to the reel being wound before it is ready in some cases, causing the yarn to be entangled or chaotic, or the reel has been placed but the reel fails to start in time, wasting production time. On the other hand, for the support and limit problem of the reel, during the winding process, the reel needs a stable support structure to ensure that it will not shake or deviate when rotating at high speed. However, when facing reels with different inner diameters, the adaptability of the support structure of some existing equipment is poor, and the reel cannot be effectively limited and supported. This not only affects the winding quality, but also may cause equipment damage due to the instability of the reel, increasing maintenance costs and downtime;

[0004] In addition, the limiting of yarn during the winding process is also an important issue. If there is no suitable limiting device, the yarn may slip off the reel during the winding process, or accumulate unevenly at both ends of the reel, affecting the flatness and compactness of the winding, which will have an adverse effect on the subsequent processing and use of the yarn. For example, it may cause uneven yarn tension during the weaving process, affecting the quality of the fabric. In addition, in the actual use of the yarn winder, a variety of complex working conditions need to be considered. For example, yarns of different materials and thicknesses have different requirements for winding. Thinner yarns may require more precise winding control to prevent yarn breakage, while thicker yarns have higher requirements for the load-bearing capacity of the reel and the stability of winding. At the same time, the diversity of the textile production environment, such as humidity, temperature and other factors, may also affect the yarn winding, requiring the winder to have better adaptability. Summary of the invention

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: the yarn winding machine based on the self-weight self-starting limited winding of the reel:

[0027] 1. The self-starting mechanism is triggered by the deadweight of the reel, which realizes the automatic start of winding. When the winding reel is placed on the support frame, its deadweight presses down the support frame, and the pressure sensor senses the pressure change and triggers the winding process. This avoids the untimely manual start and the possible errors in the start of the preset program. In the continuous production process, it can ensure that each reel can start winding at the first time it is ready, preventing the yarn from being entangled and chaotic, greatly improving the winding efficiency and quality, and reducing the yarn waste and defective products caused by starting problems;

[0028] 2. The dynamic inner support mechanism can effectively solve the support problem of winding drums with different inner diameters. The central motor drives the central gear to rotate, and drives the first displacement rod to rotate through the connecting gear. Since the threads of the two first displacement rods are in opposite directions, the first displacement seat slides toward each other on the first sliding rod, and the position of the mounting plate is automatically adjusted according to the inner diameter of the winding drum. The functional seat can further stabilize the end of the drum under the action of the hydraulic rod, and the driving wheel can drive the drum to rotate. In this way, whether it is a small or large inner diameter drum, it can get stable and appropriate support, without the need to frequently replace accessories, which greatly improves the compatibility of the equipment with drums of different specifications and the continuity of production;

[0029] 3. The limiting structure composed of the second displacement rod and the second sliding rod controlled by the adjusting motor arranged on the base can accurately adjust the position of the limiting ring. Through the threaded connection and the motor drive, the winding range of the yarn on the reel can be accurately limited according to the actual width of the reel and the requirements of the yarn winding. This effectively prevents the yarn from slipping off the reel or unevenly stacking at both ends of the reel during the winding process, ensures the flatness and compactness of the yarn winding, improves the quality of the reel after winding, and is beneficial to the subsequent storage, transportation and processing.
