Description
Technical field
The utility model relates to tailoring machinery, is specifically related to a kind of pneumatic sewing thread cutting mechanism.
Background technology
Sewing machines is to use one or more sewing thread, forms one or more stitchings on sewing, the machine that makes one or more layers sewing interweave or unite by a seam.Sewing function is made the goods such as the fabrics such as cotton, fiber crops, silk, hair, artificial fibre and leather, plastics, paper, the stitching neat appearance of stitching out, smooth firm, and sewing velocity is fast, easy to use.Sewing thread conventionally needs artificial shearing, and the many employings after improvement manually or the gear connecting rod transmission cutting mechanism of electromagnetic switch control.The defect of said mechanism is, in large-scale production, cutting mechanism uses frequent, and the loss of driving member is serious, and maintenance cost is higher, and gear connecting rod transmission cutting mechanism while using noise larger, production environment noise pollution is serious.Therefore, be necessary sewing thread cutting mechanism of the prior art to carry out architecture advances.
Utility model content
The purpose of this utility model is to overcome the defect existing in prior art, and a kind of simple in structure, noise is little, maintenance cost is low pneumatic sewing thread cutting mechanism is provided.
For realizing above-mentioned technique effect, the technical solution of the utility model is: a kind of pneumatic sewing thread cutting mechanism, it is characterized in that, described cutting mechanism comprises rotary cylinder, the rotor of described rotary cylinder is connected with rotating shaft, described rotor axially and rotating shaft axial consistent, the end of described rotating shaft is provided with blade, the blade of described blade is arranged near sewing thread.
If employing rectilinear edge, in the stubbed situation of blade, sewing thread can be along slip, shear effect is undesirable, cut off effect in order to optimize sewing thread, when under the driving of electric rotating machine, sewing thread is to blade bending part, be cut off, preferably technical scheme is, the blade of described blade is V-arrangement, and the angle on described blade both sides is not less than 90 °.
Facilitate in order to ensure that blade is whetted a knife after rust, preferably technical scheme is, the blade bending part rounding off of described blade.
For the ease of sewing thread cutting mechanism and Sewing machines are fixed, preferred technical scheme is, the rotor-end cylinder cap of described rotary cylinder is connected with fixed head, in the through hole of described fixed head, tight fit is provided with axle sleeve, described axle sleeve is connected with sewing machine stand, and the rotating shaft between described blade and rotor is located in described axle sleeve.
In order to ensure that sewing thread cutting mechanism uses safety, preferred technical scheme is, described blade place plane and described rotating shaft axially perpendicular.
In order to facilitate the replacing of blade, preferred technical scheme is to be provided with mounting knob on described blade.
In order to simplify the structure of cutting mechanism, maintain easily, preferred technical scheme is, on the blade installation end end face of described rotating shaft, be provided with screwed hole, on described blade, be provided with installing hole, screw is through described installing hole, matches with screwed hole in the thread segment top of screw.
Advantage of the present utility model and beneficial effect are:
This pneumatic sewing thread cutting mechanism is by adopting rotary cylinder to drive the blade that cuts sewing thread, compared with gear connecting rod cutting mechanism of the prior art, simple in structure, after frequent use, equipment loss is little, maintenance cost is low, and noise is low, contributes to improve production environment.

Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
Embodiment 1
As depicted in figs. 1 and 2, embodiment is a kind of pneumatic sewing thread cutting mechanism, comprises rotary cylinder 1, the rotor 2 of rotary cylinder 1 is connected with rotating shaft 3, rotor 2 axially and rotating shaft 3 axial consistent, the end of rotating shaft 3 is provided with blade 4, the blade of blade 4 is arranged near sewing thread.
In the present embodiment, the blade of blade 4 is V-arrangement, and the angle on blade both sides is not less than 90 °.
In the present embodiment, the blade bending part rounding off of blade 4.
In the present embodiment, the rotor-end cylinder cap 5 of rotary cylinder 1 is connected with fixed head 6, and in the through hole of fixed head 6, tight fit is provided with axle sleeve 7, and axle sleeve 7 is connected with sewing machine stand, and the rotating shaft 3 between blade 4 and rotor 2 is located in axle sleeve 7.
In the present embodiment, blade 4 place planes and rotating shaft 3 is axially perpendicular.
In the present embodiment, on blade 4, be provided with mounting knob 8.
In the present embodiment, on the blade installation end end face of rotating shaft 3, be provided with screwed hole, on blade 4, be provided with installing hole, screw 9 is through described installing hole, matches with screwed hole in the thread segment top of screw 9.
The pneumatic sewing thread cutting mechanism course of work is as follows:
Complete after sewing operation, operating personnel only need to hold sewing cloth, sewing thread is tightened, the rotor of rotary cylinder drives rotating shaft and blade rotation, knife-blade in cut state after rotation is pushed up mutually with sewing thread, and sewing thread slides on blade, completes cutting operation, then the rotor of rotary cylinder rotates backward, and band cutting blade is reset to state to be cut.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
