Automatic needle-threading device

Abstract

The invention discloses an automatic needle threader, which is characterized in that a rubber block with an arched surface is arranged on the upper part of the box-shaped base; The needle threading slider reciprocates and slides linearly, and the needle seat is arranged on the needle threading slider. The box-shaped base is provided with a slide block groove and a driving device, and the needle threading slide block is provided with a needle seat which fixes the sewing needle and gently presses the needle hole vertically on the thread alignment groove. When in use, lightly press the needle hole on the needle thread on the rubber block, and the driving device drives the needle seat to move back and forth, and the needle thread will arch from the needle hole to complete the needle threading. Its advantages are: simple and scientific structure, low requirements for eyesight; adopting new method and structure, utilizing the cavitation effect of pinhole, simple and fast operation, high efficiency of needle threading, overcoming the difficulty of aiming due to small pinhole, needle thread texture Soft, fluffy and loose thread ends and easy to split, making it very difficult to accurately thread the thread ends into the needle holes.

Description

technical field [0001] The invention relates to the field of needlework, in particular to an auxiliary tool for threading a needle. Background technique [0002] Tang poet Meng Jiao's "Wandering Zi Yin": the thread in the hands of a loving mother, and the clothes on the body of the wandering son. Departure thick seam, meaning fear of delay in return. Who says that the heart of an inch of grass will be rewarded with three springs! This poem describes the ordinary scene of a loving mother sewing clothes, but expresses the poet's deep inner feelings. The old mother is stitching one thread at a time, and the needles and threads are so fine and tight, because she is afraid that her son will not return home later, so she wants to sew the clothes to be stronger. A piece of pure love overflows from this ordinary and common scene, which touches the heartstrings of every reader, moves people to tears, and arouses the kind association and deep memory of the sons and daughters of the...

AI Technical Summary

Problems solved by technology

Because the pinholes are often very small and difficult to aim, the needles and threads that need to be threaded are soft in texture. Generally, the thread ends are fluffy and loose and small fibers that are easy to split. When blocked by the metal near the pinhole, the thread ends become bent and it is difficult not to pass through. As a result, it is very difficult to thread the needle and lead the thread. It takes a lot of effort to accurately insert the thread end into the pinhole, especially the chemical fiber thread has great elasticity and cannot be twisted into a sharp point. The eyesight of the elderly is reduced, it is difficult to see whether the thread has been inserted into the needle hole, and it is even more difficult to thread the needle independently

Therefore, manual threading is used. Due to the small needle mesh, it is difficult to accurately pass the thread through the needle mesh. This method requires high vision and light intensity, and it is time-consuming, laborious, and low-efficiency in operation.

[0004] In order to solve the above problems, people have invented various tools for threading and threading. There are various kinds of threading tools, each of which has its own ingenuity. Through the needle mesh, this method also needs to accurately hang the thread on the crochet needle, otherwise it is easy to have problems such as the thread not being hooked properly and the crochet needle not moving. Such an operation is also time-consuming, laborious, and inefficient.

Another example is a needle threader that uses a bell-shaped wire, but it directly passes through the pinhole by a certain hardness of the thread. For a soft nylon thread with fluff on the surface, it is difficult to pass through the small pinhole. Cannot thread multiple threads and is used for sewing needle threading

In addition, there is also a deformable needle threader made of metal wire. It relies on human vision and hands to directly pass the tip of the coil through the pinhole, and then thread the thread into the coil. Into the needle hole, this kind of needle threader is still difficult to thread, not fast, and not suitable for middle-aged and elderly people with poor eyesight

People even invented the "needle-free needle". Due to the gap at the end of the needle, the end of the needle is not strong enough, and it is easy to break when using a thimble tool, so it is difficult to popularize.

[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
