Lightweight automatic threading device

Abstract

The invention discloses a lightweight automatic needle threading device. The thread threading device comprises a fixed shell, a needle threading structure, a thread inlet column, a spring, a needle seat and a limiting opening, when the needle threading device is used, a needle needing to be threaded is placed in the limiting opening, the needle threading sliding block device is slightly pressed by a hand to enable the needle seat to penetrate through the needle opening, the needle seat hooks up the thread, and the needle thread penetrates through the needle opening to complete needle threading. The device has the advantages that the structure is simple and scientific, and the vision requirement is low; the novel method and structure are adopted, the weight is light, the production cost is low, the hole effect of the needle hole is utilized, operation is easy and fast, needle threading is efficient, and the problem that due to the fact that the needle hole is small, aiming is difficult, the texture of a needle thread is soft, and the thread end is fluffy, scattered and prone to splitting, it is very difficult to accurately penetrate the thread end into the needle hole is solved.

Description

technical field [0001] The invention relates to the field of needle and thread, in particular to a lightweight automatic needle threader. [0002] technical background [0003] In the daily life of human beings, the commonly used needles and threads are often used to sew clothes, and buttons are often changed or broken, and the thread needs to be changed. Avoid a lot of needle threading work. Because the needle hole is often very small and it is difficult to aim, the needle thread that needs to be threaded is soft in texture. Generally, the thread ends are fluffy and scattered with fine fibers that are easy to split, and are blocked by the metal near the needle hole, and the thread ends become bent. , it is difficult to penetrate, which makes it very difficult to thread the needle and lead, and it takes a lot of effort to accurately penetrate the thread into the needle hole, especially the chemical fiber thread has great elasticity, and it is difficult to directly thread the ...

AI Technical Summary

Problems solved by technology

[0003] In human's daily life, needles and threads are commonly used to mend clothes and button buttons. Threads often need to be changed due to the phenomenon of changing or breaking threads, or used in handicrafts such as cross stitch and non-woven fabrics. Threads of different types and colors are often replaced. Avoid a lot of needle threading work. Because the pinholes are often very small, it is difficult to aim. The needles and threads that need to be threaded are soft in texture. Generally, the thread ends are fluffy and loose, fine fibers and easy to split. When blocked by the metal near the pinhole, the thread ends become bent. , it is difficult to thread in, which makes it very difficult to thread the needle. It takes a lot of effort to accurately penetrate the thread end into the needle hole, especially the chemical fiber thread has great elasticity and cannot be twisted into a sharp point. It is difficult to thread the thread directly into the needle hole. In the pinhole, especially the eyesight of the elderly is reduced, it is difficult to see whether the thread end has penetrated into the pinhole, and it is even more difficult to thread the needle independently. Therefore, when threading manually, it is difficult to accurately pass the thread through the needle because of the small needle mesh. , this method has high requirements for vision and light intensity, and it is time-consuming, laborious and inefficient to operate.

[0004] In order to solve the above problems, people have invented a variety of needle threading tools, which are varied and have their own ingenious methods of use. For example, some needle threaders use bell-mouthed wires, but they rely on the hardness of the thread to pass directly through them. For the soft nylon thread with fluff on the surface, it is difficult to pass through the small pinhole, let alone thread multiple threads and be used for sewing needle threading; there is also a deformable thread made of metal wire. Needle machine, it relies on human eyesight and hands to directly pass the tip of the coil through the needle hole, then thread the thread into the coil, and when the coil is pulled out, the thread is threaded into the needle hole. This kind of needle threader is still difficult to thread. Big, not fast, not suitable for middle-aged and elderly people with poor eyesight. People also invented the "needle-free needle". Because there is a gap at the end of this needle, the end is not strong enough, and it is easy to break when using a thimble tool, so it is difficult to to promote

[0005] Moreover, these needle threading tools all have the following defects, that is, they exist independently as an individual and cannot be integrated with the needle and thread carrier, resulting in inconvenient use and storage; more complicated, large in size, and inconvenient to store; and the cost is relatively high

It cannot be accepted by users, and it is difficult to be popularized and promoted in the end
