Abstract
The utility model discloses a thread cutting mechanism of a sewing machine, which comprises a thread cutting tool, and is characterized in that the thread cutting mechanism further comprises a thread suction groove; one end of the thread suction groove is connected with a pipe of an air suction mechanism of the sewing machine; a thread suction opening is arranged at the other end thereof; and the thread suction opening is opposite to the cutting part of the thread cutting tool. The utility model can pull up the end of a thread stuck to the surface of clothes, so that the thread cutting mechanism can be utilized to treat the end of the thread, and the treatment effect of the end of the thread can be further improved.
Description
Technical field
The utility model relates to a kind of Sewing machines thread cutting mechanism.
Background technology
Clothes have things such as sewing line, elastic cord, elastic and link to each other in the process of making between garment piece and the garment piece, must they be cut off, and just can flow into down operation production.In the past, these sewing lines, elastic cord, elastic need be cut off with artificial or machine.After cutting off with machine, owing to can stay long (sewing line, elastic cord, elastic) head, need be with manually cutting once again.Not only all efficient is low for two kinds of methods, but also has influence on the quality of clothes.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provide a kind of can the end of a thread, degree of tightness be taken the lead with making, the Sewing machines thread cutting mechanism handled again after stretching of elastic head.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of Sewing machines thread cutting mechanism comprises the trimming cutter, it is characterized in that it comprises that also one inhales wire casing, and an end of inhaling wire casing is connected with Sewing machines air draught mechanism pipeline, and the other end is provided with suction line mouth, and described suction line mouth is relative with the shearing position of trimming cutter.
As the utility model preferred embodiment, described trimming cutter comprises a tool rest, connect in the tool rest cutter shaft is installed, the two ends of cutter shaft are equipped with axle sleeve, one end of tool rest is equipped with stationary knife, at an end of cutter shaft moving knife is installed, and sewing line, elastic cord, elastic can be by the space between the blade of stationary knife and moving knife, the other end of cutter shaft is installed with and drives the pivoted arm that cutter shaft rotates, and described suction line mouth is relative with the moving knife position with stationary knife.
As the improvement of the above-mentioned embodiment of the utility model, described suction wire casing is provided with installing plate, and installing plate is provided with installing hole or mounting groove.
The beneficial effects of the utility model are: thread cutting mechanism of the present utility model also is provided with the suction wire casing that is connected with air draught mechanism, an end of inhaling wire casing is provided with inhales the line mouth, can be by inhaling wire casing with stretching with sewing line, elastic cord, the elastic of clothing surface adhesion, facilitating the use thread cutting mechanism handles it, and then the effect of raising shearing, whole shearings are finished by machine, have improved production efficiency and quality widely.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a perspective exploded view of the present utility model.
The specific embodiment
With reference to Fig. 1, the disclosed a kind of Sewing machines thread cutting mechanism of the utility model, comprise a trimming cutter and a suction wire casing 1, an end of inhaling wire casing 1 is connected with Sewing machines air draught mechanism pipeline, and the other end is provided with suction line mouth 2, and suction line mouth 2 is relative with the shearing position of trimming cutter, air draught mechanism makes inhales certain negative pressure that line mouth place produces, thereby will with the end of a thread pull-up of clothing surface adhesion, facilitate the use thread cutting mechanism it handled, and then improve the effect that the end of a thread is handled.
Inhale wire casing 1 and be provided with installing plate 3, installing plate 3 is provided with installing hole or mounting groove 4, is installed on the trimming machine so that will inhale wire casing.
In embodiment as shown in the figure, the trimming cutter comprises a tool rest 5, be provided with axis hole 6 in the tool rest 5, the two ends of axis hole 6 are equipped with axle sleeve 7, cutter shaft 8 is installed in the axis hole 6, the two ends of cutter shaft 8 are installed in the axle sleeve 7, end at tool rest 5 is equipped with stationary knife 11 by screw 9 and pin 10, end at cutter shaft 8 is equipped with moving knife 12, sewing line can be by the space between the blade of stationary knife 11 and moving knife 12, the other end of cutter shaft 8 is installed with and drives the pivoted arm 13 that cutter shaft 8 rotates, and pivoted arm 13 is provided with the power transmission shaft 14 that can connect with external drive power, and it is relative with the position of stationary knife and moving knife wherein to inhale line mouth 2.
Certainly, the utility model also can adopt the trimming cutter of other structure, is not described further at this.
