Description
[technical field]
The utility model relates to a kind of thread-loosening device for sewing machine, is specifically related to a kind of computer overlock machine loose ends device, belongs to sewing-machine equipment technical field.
[background technology]
In various computer package Sewing machines, thread-loosening device is the unit that can not lack because overseam thread beginning and power cut-off need tangent line time, usually need overlock machine upper thread to be in loose ends state.The time of loose ends process holds and state not only has influence on shearing quality, also has influence on the labour intensity of operator.Because existing overlock machine loose ends device exists following defect:
1. be not easy trimming after inconvenient workman's threading and job done clothes;
2. can not control the length of the end of a thread, stitching unsightly, has some setbacks;
3. finish clothes ending and easily beat Zou;
4. tangent line is unstable, installation is inconvenient, service life is not long.
Therefore, for avoiding above-mentioned technical problem, the necessary one that provides has structure improved computer overlock machine loose ends device, to overcome described defect of the prior art.
[utility model content]
In order to overcome above shortcomings part in prior art, the purpose of this utility model is to provide a kind of computer overlock machine loose ends device.
In order to reach above-mentioned object, the utility model adopts following concrete technical scheme: computer overlock machine loose ends device, comprise and there is support bracket fastened loose ends device frame, fixed support is provided with bracket holes, described loose ends device frame front is provided with the fixing thread tension releasing disc of binodal screw, self-return cylinder is installed after it, self-return cylinder one end is provided with the cylinder turnover pull bar moved left and right for promoting thread tension releasing disc, its other end is provided with air inlet gas-tpe fitting, described air inlet gas-tpe fitting is provided with the nut for adjustable pressure size.
Further, thread tension releasing disc described in the utility model is tabular shape, and its lower end has two claws, and claw is positioned at loose ends device fixed support side.
The utility model advantage is compared with prior art:
1. facilitate workman's threading, facilitate workman to finish the relatively good trimming of clothes;
2. can control the length of the end of a thread, stitching is beautiful, smooth and easy;
3. clothes ending can not beat Zou;
4. the utility model adopts stainless steel and ironware to make, and simplicity of design is easy for installation, durable in use;
4. the utility model coordinates cylinder or electromagnet, and controls completing of line sending time by automatically controlled, operates easier.
[accompanying drawing explanation]
Fig. 1 is front elevation of the present utility model;
Fig. 2 is back view of the present utility model;
Below in conjunction with accompanying drawing, the utility model is described in further detail.
[detailed description of the invention]
In order to explain the technical solution of the utility model further, below by specific embodiment, the utility model is elaborated.
Refer to shown in Figure of description 1 and Fig. 2, the utility model is computer overlock machine loose ends device, comprise the loose ends device frame 2 with fixed support 8, fixed support 8 is provided with bracket holes 9, described loose ends device frame 2 front is provided with the fixing thread tension releasing disc 7 of screw 6, self-return cylinder 5 is installed after it, self-return cylinder 5 one end is provided with the cylinder turnover pull bar 1 moved left and right for promoting thread tension releasing disc 7, its other end is provided with air inlet gas-tpe fitting 3, air inlet gas-tpe fitting 3 is connected with electromagnetism Pneumatic valve gas outlet, for cylinder provides Gas Energy Source, air inlet gas-tpe fitting 3 is also provided with the nut 4 for adjustable pressure size, promote degree of tightness by air pressure size to thread tension releasing disc to control.
It should be noted that, thread tension releasing disc 7 described in the utility model is tabular shape, its lower end has two claws 71, claw 71 is positioned at loose ends device fixed support 8 side, when in cylinder without gas pressure time, claw and the device side line tension disc of thread tension releasing disc have been in gap state, when the gas pressure in cylinder reaches certain atmospheric pressure, air cylinder tie rod outwards (left side) is mobile, and drive the claw of thread tension releasing disc to be moved to the left, claw and upper thread tension disc close contact also promote two pieces of upper thread tension discs simultaneously and unclamp and make upper thread be in loose ends state, the control of loose ends time is by automatically controlled, electronic valve, electric eye, coordinate this action.
The part used in above-described embodiment, as self-return cylinder, loose ends device frame, thread tension releasing disc, etc., process by stainless steel material.
But above-mentioned detailed description of the invention is exemplary, being to better enable those skilled in the art understand this patent, can not being interpreted as it is restriction this patent being comprised to scope; As long as according to this patent disclose any equivalent change done or the modification of spirit, all fall into the scope that this patent comprises.
