The application provides a kind of control mechanism for eliminating needlework on fabric, is used for sewing machine 2.Will to sew convenient for narration
The moving direction of cloth in sewing of machine 2 is defined as front direction；Therefore, in view shown in Fig. 3, the upper side and lower side point of paper
Not Wei front direction and rear direction, the left and right side of paper is respectively left direction and right direction, the front and back difference of paper
For upper direction and lower direction.
As shown in Figure 4 and Figure 5, a kind of sewing machine 2 provided herein has electronic control module, needle plate in the sewing machine 2
21, the control mechanism of needlework, control mechanism are used for upper thread line when playing seam on the eedle 22 and elimination fabric extended up and down
Head is pulled to the lower section of needle plate 21, and then so that upper thread the end of a thread is located at the back side of cloth and non-frontal.As shown in Figure 1 to Figure 3, the application
The control mechanism of needlework includes driving source 3, transmission component and movable hooking knife 4 on a kind of elimination fabric provided, is hooked
Line knife 4 is located at 21 lower section of needle plate and has the hooking portion 41 for catching on wire loop 1, and driving source 3 passes through transmission component and hooking knife
4 are connected, the hooking portion 41 on driving hooking knife 4 move to the direction close to or far from eedle 22, driving source 3 by signal wire and
Electronic control module is connected.
Further, the application also provides a kind of control method for eliminating needlework on fabric, is used for sewing machine 2；Such as Fig. 4 and
Shown in Fig. 5, in sewing machine 2 have needle plate 21 and eedle 22, control method the following steps are included:
S1, control mechanism as described above is set in sewing machine 2；
Before S2, seam, the presser feet in sewing machine 2 is lifted, convenient for placing cloth, and hooking portion 41 is away from eedle 22, upper thread
In the top of presser feet, upper thread is threaded through in eedle 22 upper thread the end of a thread of end, and upper thread the end of a thread is in the side of eedle 22；
S3, it is put into cloth, presser feet puts down, overlays cloth；
S4, seam is played, sewing machine 2 operates；When sewing the first needle, the eedle 22 in sewing machine 2 is during rise, eedle
22 make upper thread form the wire loop 1 for being located at the lower section of needle plate 21, the both ends of wire loop 1 be respectively by tension disk in sewing machine 2 clamp by
Power end and the free end being made of upper thread the end of a thread；Electric control module controls driving source 3 acts, then driving source 3 passes through transmission component
Hooking portion 41 on driving hooking knife 4 is moved to the direction close to eedle 22, and hooking portion 41 is made to catch on wire loop 1；Later, automatically controlled mould
Block controls driving source 3 and reoperates, and driving source 3 drives the hooking portion 41 on hooking knife 4 to separate eedle 22 by transmission component
Direction movement, then hooking portion 41 drives the free end of wire loop 1 together far from eedle 22；
S5, sewing machine 2 remain in operation, cloth Forward, and the free end of wire loop 1 is pulled to 21 lower section of needle plate；After sewing,
Presser feet is lifted, takes out cloth, then upper thread the end of a thread is located at the back side of cloth.
Therefore, the application can be drawn the free end (i.e. upper thread the end of a thread) of wire loop 1 by control mechanism above needle plate 21
To needle plate 21, and then upper thread the end of a thread is made to be formed in the back side of cloth, guarantees the beauty and sewing quality of sewing efficiency.
Further, in order to rise seam before guarantee upper thread end upper thread the end of a thread in the top of presser feet, can be in sewing machine 2
Blowning installation is set or dials line device 26；When blowning installation is arranged in sewing machine 2, blowning installation has blowing for alignment upper thread the end of a thread
Port；In step S2, the inflatable mouth of blowning installation is blown to upper thread the end of a thread, and upper thread the end of a thread is made to be located at the top of presser feet；Work as sewing
When line device 26 is dialled in setting in machine 2, acts on upper thread as shown in figure 4, dialling line device 26, upper thread can be picked up；Step S2 exists, and dials line device
Upper thread is picked up in 26 movements, and upper thread the end of a thread is made to be located at the top of presser feet.
In order to realize the full-automatic sewing of sewing machine 2, the sewing machine 2 in the application is additionally provided with foot pedal, automatic shearing
Mechanism and foot lifting mechanism.The detection sensor that state is stepped on for detecting foot pedal, detection sensor are provided on foot pedal
