Description
Technical Field
The invention belongs to the field of industrial sewing machine sewing, and relates to a method for preparing a threading guide line for a sewing machine.
Background
At present, threading is a difficult problem in the sewing process of an industrial sewing machine, and a sewing thread on a sewing machine can only generate normal stitch in the sewing process after passing through a plurality of thread passing holes and internal mechanisms of the sewing machine.
Due to the development and transition of the market, the types of sewing threads related to sewing are more and more, such as elastic threads of silk threads and the like, various threads cannot normally pass through each threading hole and mechanism on a sewing machine, most factories commonly adopt metal tweezers to clamp line segments for delivery threading at present, so that a great deal of time is wasted, the tweezers are not efficient, machine threading holes are frequently poked or machine internal parts are damaged, needles are touched, an auxiliary tool capable of threading is needed, but the existing threads cannot basically play a role of a convenient threading tool, and the guide line is specially developed and manufactured.
Disclosure of Invention
The object of the present invention is to solve the above-mentioned problems of the prior art and to provide a threading guide wire for a sewing machine which is inexpensive and durable.
The aim of the invention can be achieved by the following technical scheme:
a method of preparing a threading guide wire for a sewing machine, the method comprising the steps of: the nylon wire is firstly processed by fluorocarbon coating, and is twisted in half after being cut, then the nylon wire is heated, frozen and shaped, and finally the threading guide wire is obtained by soaking in lubricant.
In the above-mentioned threading guide wire preparation method for sewing machine, the fluorocarbon coating specifically comprises: uniformly covering the surface of the nylon wire with a coating containing fluorocarbon molecules, and then carrying out ultraviolet irradiation curing for 3-8 min.
Preferably, the fluorocarbon molecule-containing coating has a thickness of 1 to 3um.
In the above-mentioned method for preparing threading guide wire for sewing machine, the heating treatment is divided into preheating and secondary heating.
In the method for preparing the threading guide wire for the sewing machine, the preheating temperature is 45-55 ℃ and the preheating time is 0.5-1.5min. The invention firstly preheats at 45-55 ℃ to lead the nylon wires to generate tension, if the temperature is too high, the wires cannot be made into products or directly jump, and if the temperature is too low, the wires cannot have enough torsion space to break.
Preferably, the nylon wire is twisted by a motor-driven machine after preheating.
In the method for preparing the threading guide wire for the sewing machine, the second heating temperature is 65-75 ℃ and the time is 1-3min. The invention shapes the silk thread at 65-75 ℃, if the temperature is too high, the twisted silk thread is excessively expanded to be loosened, and if the temperature is too low, the bonding and shaping can not be carried out.
In the method for preparing the threading guide wire for the sewing machine, the freezing setting temperature is minus 5-15 ℃ and the time is 1-3h. The frozen and shaped part has the advantages that the two threads are in a firmer bonding state after further shrinkage and solidification, and the two threads are not scattered along with the change of external environment after shaping and stabilization.
In the above-mentioned threading guide wire preparation method for sewing machine, the lubricant is white oil.
In the method for preparing the threading guide wire for the sewing machine, the soaking time is 25-35min.
According to the invention, the nylon yarn is soaked in the white oil, so that the effect of softening and solidifying can be achieved, and the lubrication passing property of the yarn can be improved.
Compared with the prior art, the invention has the following beneficial effects: the threading guide wire for the sewing machine is just threaded and does not damage a threading hole of the machine, the line section is not thick, thin and scattered, just can just pass through each threading hole of the machine, is durable after being processed, reduces the difficult problem of threading various threads, greatly improves the working efficiency, well protects the service life of the machine lifting machine, and is simple in preparation method and suitable for large-scale industrial production.
