A kind of industrial sewing machine plays the suture head controlling device

Technical field

The utility model relates to a kind of parts improved device of industrial sewing machine, is specifically related to an a kind of suture head controlling device of industrial sewing machine.

Background technology

Existing industrial sewing machine can pull out the line function after having automatic tangent automatically, its pull out behind the purpose sewing finishing tangent line of line the end of a thread of leaving on the eedle pull out on the sewing surface for make for the second time front can the end of a thread by eedle take to sewing below, play and make unified effect attractive in appearance.This wire drawer is mounted in the Sewing machines back side transfers sewing machine needle again by installing plate support, operating magnet, pulling and connecting rod and rotating shaft etc. the right, steel wire etc. the bending by the right after the sewing finishing pulls up suture come, so high complex structure of wire drawer manufacturing cost, large working space and the visual angle of affecting of volume, the most terribly be that the crooked steel wire pin on eedle the right can collude sewing can affect real work the time, workman's hand formula be to also can getting to staff when pulling out line, or debugs the problems such as eedle that also interrupt not in place.

The utility model content

The purpose of this utility model provides a kind of Sewing machines simple in structure and plays the suture head controlling device, can overcome the defective of prior art, when playing seam, can make the sewing thread above the eedle no longer be continued to take out of, directly controlled the suture head below sewing, do not needed suture to be pulled out line when to be finished and prepare for playing seam next time to the sewing surface.

The purpose of this utility model is achieved through the following technical solutions:

A kind of industrial sewing machine plays the suture head controlling device, it is characterized in that:

Three directions of configuration all are bent into the dustpan-shaped support in interior right angle upwards above the eedle of head of sewing machine bottom, and wherein the back extends upward, and offers circular hole, and support is fixed on the head by screw;

T clevis the end of a thread is set in the front of support, wherein the rectangular platen of T clevis the end of a thread and front in opposite directions, the depression bar handle that T clevis the end of a thread is vertical with pressing plate penetrates the front of support, is coaxial docking with the adhesive electromagnet that is configured on the circular hole of support back;

The adhesive electromagnet has two states, when when energising, the depression bar handle of T clevis the end of a thread backward or mobile, pressing plate is fitted with the front, when cutting off the power supply, the depression bar handle of T clevis the end of a thread moves forward, pressing plate separates with the front;

The adhesive electromagnet is by computer control energising or outage.

Adopt the technical program, eedle is worked downwards when industrial sewing machine plays seam, play the energising of suture head controlling device, the depression bar handle of T clevis the end of a thread backward or mobile, fitting in pressing plate and front, plays the suture head and be clamped between pressing plate and the front, controlled the suture head and do not elongated by eedle, just take away the end of a thread of making last time beyond leaving on the eedle to sewing below rotating shuttle ditch line and lock knot when eedle continues down motion, reach when having made the end of a thread and return below the sewing.When eedle is got back to the extreme higher position, play the outage of suture head controlling device, the depression bar handle of T clevis the end of a thread moves forward, and pressing plate separates with the front and does not clamp, and enters the common not clamp state of making.

Further, offer screwed hole on the base of described support, by the wire steel wire of screw fixed guide sewing thread.

Further again, described wire steel wire bends to screw connecting hole and sewing thread wire openings hole by a steel wire bending forming.

Further, offering a bayonet socket at the depression bar of T clevis the end of a thread packs into and prevents the spacing jump ring that T clevis the end of a thread is deviate from.

Sequential, angle and the time of further, switching on, cutting off the power supply by computer control adhesive electromagnet.

Further, offer on the base of described support and shank cover and depression bar cover corresponding hole, position.

Further, the depression bar handle of described T clevis the end of a thread is moved forward by urgent its of the spring in the adhesive electromagnet.

The beneficial effects of the utility model are, the utility model device simple in structure, employing arranges T clevis the end of a thread in the front of support, the depression bar handle that T clevis the end of a thread is vertical with pressing plate penetrates the front of support, is coaxial docking with the adhesive electromagnet that is configured on the circular hole of support back; The adhesive electromagnet has two states, when when energising, the depression bar handle of T clevis the end of a thread backward or mobile, pressing plate is fitted with the front, on the contrary when cutting off the power supply, the depression bar handle of T clevis the end of a thread moves forward, pressing plate separates with the front.Reach the purpose of having controlled the suture head, and this apparatus structure is simple, compact, low cost of manufacture does not affect working space and visual angle, and the crooked steel wire pin of having stopped eedle the right in the prior art can collude sewing, pull out the line staff of easily injuring, easily interrupting the problem of eedle.
