Abstract
The invention discloses a kind of auxiliary threaders applied to unlimited rotary needle rod sewing machine, it is related to sewing machine field of mechanical technique, the present invention includes the inflatable body that therefrom the lower stomidium of empty needle bar is pierced by after being arranged on sewing machine and the upper end hole of sewing thread therefrom empty needle bar capable of being allowed to penetrate by way of air blowing；The present invention has structure simple, solves the technical problem that the sewing machine threading with unlimited rotating the needle bar is difficult in the prior art.
Description
Technical field
The present invention relates to sewing machine field of mechanical technique, are applied to unlimited rotary shank more particularly to one kind and sew
The auxiliary threader of machine.
Background technique
The patent of applicant's earlier application, number of patent application are as follows: 201910093216.6, patent name are as follows: " one kind can
The needle bar of sewing machine and take-up mechanism wirelessly rotated ", in disclose " by take-up mechanism sewing thread can pass through shank in
Empty region and pin hole directly through eedle, its sewing thread will not be wrapped on shank when shank rotation, and shank can
Unlimitedly to rotate " technical solution, using or needing replacing sewing for the first time when this programme is in practice
When line, the lower end for needing the upper end by sewing thread therefrom empty needle bar to penetrate last therefrom empty needle bar is pierced by, but due to sewing
Line is excessively soft, can not be without other tools directly through hollow shank, and traditional approach is to assist threading with iron wire,
One end of the end of a thread of sewing thread and iron wire is fastened, the upper end of the one end for fastening the iron wire of sewing thread therefrom empty needle bar is penetrated,
Finally therefrom the lower stomidium of empty needle bar is pierced by, then sewing thread is removed from iron wire, then extracts iron wire, and this completes will
Sewing thread passes through the operation of hollow shank.
But this mode of operation excessively delays the threading time of sewing machine operator, while the sundries such as iron wire are placed on
Normal sewing operation is interfered in sewing work on-the-spot meeting, and still more iron wire is easy to stab the hand of operator, while iron wire is thin
Long part store it is very troublesome, if the end for storing improper iron wire is likely to the cloth that will be being sewed or leatherware and draws
Wound causes unnecessary economic loss for company or enterprise.
Summary of the invention
It is an object of the invention to: in order to solve the technologies such as the existing threading difficulty of sewing machine with wireless rotation shank
Problem, the present invention provide a kind of auxiliary threader applied to unlimited rotary needle rod sewing machine.
The present invention specifically uses following technical scheme to achieve the goals above:
A kind of auxiliary threader applied to unlimited rotary needle rod sewing machine, including be arranged on sewing machine and can lead to
Cross the air feeder that therefrom the lower stomidium of empty needle bar is pierced by after the mode blown allows the upper end hole of sewing thread therefrom empty needle bar to penetrate
Structure.
Further, the inflatable body includes the air flue that can blow air into the upper end hole of hollow shank, Yi Jineng
Enough the valve of control air flue opening and closing, one end of valve are connected to air flue, and the other end and gas source service of valve are connected.
Further, the gas outlet of the air flue is directed at the aperture of the upper end hole of hollow shank, the air inlet and valve of air flue
The gas outlet connection of door, the air inlet and compressed air pipe of valve are connected.
The end of a thread of sewing thread: being placed on the aperture of the upper end hole of hollow shank by working principle, and Open valve makes compression empty
Gas is blown into hollow shank by air flue, allow air-flow by the end of a thread of sewing thread therefrom empty needle bar lower end outlet blow out.
Beneficial effects of the present invention are as follows:
The present invention allows compressed air to be blown into hollow shank by air flue by what is blown, finally by air-flow by sewing thread
The end of a thread therefrom empty needle bar lower end outlet blowout, save the time of threading, reduce operator threading etc. non-normal workings appoint
The time delayed in business, production efficiency is improved indirectly；After the present invention is mounted on sewing machine simultaneously, can directly it exempt from
The tool for removing other auxiliary threading such as iron wire, makes the scene of production cleaner and tidier, the 6S management of enterprise easy to produce, with further
Improve production efficiency；After eliminating iron wire auxiliary threading, also avoids iron wire and wait the product of sewing to scratch cloth leatherware
Risk, further increase product seam product quality assurance, improve the economic benefit of enterprise.
