Abstract
The utility model relates to a stitch loosening control device for a sewing machine. The stitch loosening control device for the sewing machine mainly adopts the technical scheme that an electromagnetic power source drives a linkage rod piece to make an actuating part at one end of the linkage rod piece drive a control piece pivoted with a connecting rod piece, so that a stitch loosening device can achieve a power-driven stitch loosening status under the control of a propping and pressing plate of the control piece; and in case of a manual stitch loosening status, when the connecting rod piece is pushed and propped by hand, a control end of the control piece is separated from a limit propping and pulling end which is propped against the actuating part of the linkage rod piece and moves towards a loosening and releasing end without limit, and at the same time, the stitch loosening device is propped and pressed by the propping and pressing plate of the control piece for manual stitch loosening. Therefore, operators can freely adjust the stitch tightness as needed.
Description
Technical field
The utility model is relevant for a kind of Sewing machines loose ends control device; Especially refer to a kind of via the design that unclasps end; Let thread-loosening device unclamp thread-loosening device with the manual operation link member and unrestricted, can freely adjust the start of loose ends state and the Sewing machines loose ends control device of stroke according to required.
Background technology
General Sewing machines structure, when Sewing machines work at the end, can impose a signal and give electromagnetic valve; The stroke that lets electromagnetic valve work one be compressed to after protruding out; Usually the operating bar first end pivot of this electromagnetic valve connects a thread cutting device, and the start interlock thread cutting device via electromagnetic valve protrudes out to car pin place with plastic cutter; And thread is colluded the cut-out of pulling; Via the cooperation of some linkages, the thread-loosening device of Sewing machines front side can synchronously be relaxed the suture that is folded on the tensioning device at the operating bar second end place of electromagnetic valve, the suture that just can make thread cutting device will be positioned at the thread position is outwards pulled out the step that laggard row is cut off; So, just can carry out next sewing work.And the tensioning device of Sewing machines is lax; The linkage that mainly utilizes electromagnetic valve operating bar second end to be connected; Interlock is dialled the arm of dialling that commentaries on classics one is positioned at the Sewing machines front side; This group arm is passed up or down look different type of machines up or down and is decided], and reach synchronously thread-loosening device loose ends, the purpose of raising line.
With regard to aforementioned structure just like bulletin M344350 number " Sewing machines raise line, thread-loosening device "; Or like the previous bulletin of the utility model people No. 363622 " the automatic loose ends jockey of industrial sewing machine ", M379608 number " a kind of Sewing machines loose ends control device "; M351884 number for another example " be used for the electricity of thread cutting device drives the formula transmission mechanism under the Sewing machines "; It mainly drives the interlock rod member via the electromagnetic power source this Sewing machines loose ends control, and interlock rod member one end is provided with slot part, and correspondence is pivoted with control lever one end in the slot part; And control lever and connecting rod articulate, to let connecting rod control thread-loosening device form power-actuated loose ends state; Yet; To adjust under the situation that suture needs thread-loosening device is unclamped, having because the slot part of interlock rod member is spacing fixing with control lever, therefore when the not start of electromagnetic power source; Can't push tensioning device open by the line rod end of raising of thread-loosening device at all; Promote connecting rod simultaneously and change the position of control lever, relatively promptly can't adopt manual mode to reach the adjustment thread-loosening device, still need pedal to impose a signal and drive the electromagnetic power source thread-loosening device is unclamped.
Therefore; In view of this utility model inventor adheres to for many years the abundant of these relevant industries and designs and develops and the actual fabrication experience, studies improvement to existing structure and disappearance; A kind of Sewing machines loose ends control device is provided, in the hope of reaching the purpose of better practical value.
The utility model content
The main purpose of the Sewing machines loose ends control device of the utility model be to change thread-loosening device because of power drive so limited start and the stroke that can't freely adjust the loose ends state; Use the design that unclasps end, thread-loosening device can unclamped thread-loosening device manually to push link member and freely be adjusted into purpose according to required.
The purpose of the utility model Sewing machines loose ends control device and effect are realized by following technology:
It mainly drives the interlock rod member via the electromagnetic power source; And the Actuator Division that makes interlock rod member one end drives the control piece that articulates with link member; To let the plate control thread-loosening device that compresses of control piece form power-actuated loose ends state; And when the time via manual loose ends state; Its manually pushing and pressing link member and let the control end of control piece break away from interlock rod member Actuator Division against the spacing end of pulling that supports can be toward unclasping end movement and not limited, and let the plate that compresses of control piece compress thread-loosening device and reach manual loose ends purpose synchronously; By this, let the operator can be according to required and carry out freely adjusting of suture degree of tightness.
