Problems solved by technology
In traditional sewing machines, when the upper thread breaks, it is necessary to re-thread the upper thread into the eye of the needle, but the eye of the needle is generally thin, and the user cannot thread the upper thread into the eye of the needle in a short time. Especially for the elderly or people with poor eyesight, it takes a lot of time to operate

The invention provides an automatic threading device for a sewing machine, and belongs to the technical field of sewing machines. The automatic threading device for the sewing machine solves the problem that threading is troublesome when threads of sewing needles of existing sewing machines are broken. The automatic threading device for the sewing machine comprises a support, wherein a threading shaft and a needle bar are arranged on the support in parallel, a first installation base, a second installation base and a third installation base are sequentially arranged on the support from top to bottom, the needle bar penetrates through the first installation base and the third installation base and can move axially, the automatic threading shaft penetrates through the second installation base and the third installation base and can move axially, a sewing machine is arranged at the lower end of the needle bar, the automatic threading shaft is connected with a transmission bar in a sleeved mode, the lower end of the automatic threading shaft is fixedly connected with a threading needle, a rotating mechanism is arranged between the automatic threading shaft and the transmission bar and can enable the automatic threading shaft to rotate circumferentially and enable the threading needle to penetrate into the eye of the sewing needle. The automatic threading device for the sewing machine has the advantages of being simple in structure, practical and convenient to use.
Description
technical field [0001] The invention belongs to the technical field of sewing machines, in particular to an automatic threader for sewing machines. Background technique [0002] A conventional sewing machine has many threading components (thread tension adjuster, thread take-up spring, thread take-up lever, needle bar thread guide, etc.), through which the upper thread from the bobbin passes, and then passes through these threading components in a predetermined order and path. After threading the parts, the upper thread is passed through the eyelet of a sewing needle attached to the needle bar. In traditional sewing machines, when the upper thread breaks, it is necessary to re-thread the upper thread into the eye of the needle, but the eye of the needle is generally thin, and the user cannot thread the upper thread into the eye of the needle in a short time. Especially for the elderly or those with poor eyesight, it takes a lot of time to operate. Contents of the inventio...
