Description
Technical Field
The invention relates to the technical field of stitch embroidery processing, in particular to a method for removing excess threads of a bottom thread by a hot method.
Background
In the current technical field of stitch embroidery, a bobbin thread is usually wound on a thread core, and then the thread core is installed in stitch embroidery machines such as an embroidery machine. When the bottom line needs to be replaced, the method for removing the remaining bottom line on the line core is mainly divided into two types: firstly, finding out the thread end of the bottom thread, and then manually pulling off the remaining thread of the bottom thread; and secondly, after finding the thread end, winding the thread end on a motor shaft, and then pulling out the residual thread of the bottom thread through the rotation of the motor shaft.
The above prior art solutions have the following drawbacks: in the two methods, the thread end needs to be found firstly, then the remaining bottom thread is pulled off from the thread core by pulling the thread end, and sometimes, a processing worker can cause low bottom thread removing efficiency because the thread end of the bottom thread cannot be found or the bottom thread is knotted in the pulling-off process.
Disclosure of Invention
The invention aims to provide a method for removing the residual bottom line by a thermal method, which directly leads the bottom line wound on a line core to be subjected to hot melt fracture by a heating method so as to achieve the aim of quickly removing the residual bottom line.
The above object of the present invention is achieved by the following technical solutions:
a method for removing excess lines of a bottom line by a hot method comprises the following steps:
firstly, taking out a wire core from a sewing and embroidering machine, and then separating a core body wound with a bottom thread from a wire core shell;
secondly, fixing the core body;
thirdly, heating the core body by using a heating source until the bottom line is melted and broken and leaves the core body;
and fourthly, closing the heating source, loosening the core body and reinstalling the core body and the core shell.
By adopting the technical scheme, the efficiency of removing the remaining bottom line is greatly improved. The traditional method of pulling out the remaining thread of the bottom thread by hand or motor is generally adopted, but both methods need to find out the thread end firstly, and the step of finding the thread end can waste much time. Then, in the process of pulling the remaining bottom line from the line core, the pulling step may be stopped due to the knotting of the bottom line, and more time is needed for rearranging the line. The method directly heats the bottom line residual line on the line core so as to lead the bottom line residual line to be subjected to hot melting fracture, saves the time for searching the line head and pulling and removing the bottom line residual line, and is also favorable for avoiding the condition that the pulling and removing steps are stopped because the bottom line is knotted. In addition, for the bottom thread made of pure cotton or blended cotton, the phenomenon that the thread velvet scatters can be inevitably generated by pulling off the bottom thread by using manual pulling or motor winding, and the production of the thread velvet can be greatly reduced by removing the residual thread of the bottom thread by a heating method, so that the environment is kept clean, and the trouble of subsequent cleaning of processing personnel is reduced.

The metal cannot be heated by the microwaves because the metal reflects the microwaves, so that the wire core is not worried about being damaged by the microwaves when the microwave is used for heating the wire core.
The invention is further configured to: the heating source is a hot air generator, and a flat nozzle used for gathering hot air is sleeved at an air outlet of the hot air generator, so that the flat nozzle is aligned to the core body and moves axially back and forth relative to the core body.
Through adopting above-mentioned technical scheme, establish the flat mouth at the air outlet cover of hot-blast generator, be favorable to gathering hot-blast. The area of the air outlet is reduced by arranging the flat nozzle so as to improve the output speed of hot air, and the hot air blade is favorably formed and the residual bottom line on the core body is cut.
The invention is further configured to: the heating source is a vortex heating device, the vortex heating device is used for heating the cutting body, then the cutting body is moved, one end of the cutting body is close to the bottom line on the core body, and the bottom line is fused, broken and separated from the core body.
Through adopting above-mentioned technical scheme, in placing the cutting body in the electromagnetic field of high frequency variation, powerful electromagnetic field forms the response vortex on the cutting body surface, relies on the internal resistance of cutting body material itself, makes it generate heat fast to fuse the bottom line excess line through removing the cutting body.

In addition, the electric heating element has the characteristics of simple structure and convenient operation.
The invention is further configured to: the electric heating element is an electric iron.
By adopting the technical scheme, the electric soldering iron is used as the heating source, so that the cost is reduced, and the electric soldering iron is convenient to operate due to the small size.
The invention is further configured to: the soldering iron head of the electric soldering iron is a sharp head.
Through adopting above-mentioned technical scheme, the soldering iron that uses the tip is favorable to the electric iron to adapt to the narrow and small condition in sinle silk wire winding space and realizes meticulous operation.
In conclusion, the beneficial technical effects of the invention are as follows:
1. thereby heat through directly making it take place the hot melt fracture to the bottom line excess line on the sinle silk, saved and look for the end of a thread and pull the required time of removing the bottom line excess line, also be favorable to avoiding simultaneously because of the bottom line takes place to tie a knot and leads to pulling the condition of removing the step stagnation.
2. For the bottom thread made of pure cotton or blended cotton, the phenomenon that the thread velvet scatters can be inevitably generated by pulling off the bottom thread by manual pulling or motor winding, and the production of the thread velvet can be greatly reduced by removing the residual thread of the bottom thread by a heating method, so that the environment is kept clean and tidy, and the trouble of subsequent cleaning of processing personnel is reduced.
3. The laser emitter is used as a heating source, and laser beams are directly irradiated on the bottom line, so that the purpose of quickly fusing the bottom line is achieved. Meanwhile, the laser emitter is used as a heating source, so that remote control operation is easy to realize, mechanization and automation are easy to realize, and the personal safety of processing personnel is protected.
