Description
Technical field
The utility model relates to industrial sewing machine field, and what be specifically related to a kind of Sewing machines plays suture head controlling device.
Background technology
The function of line is also automatically pulled out after existing industrial sewing machine has automatic tangent, its object of pulling out line after sewing finishing tangent line, the end of a thread that eedle is left over is pulled out sewing can the end of a thread be taken to below sewing by eedle before making for the second time on the surface, plays and make unified effect attractive in appearance.This wire drawer be mounted in the Sewing machines back side by installing plate support, operating magnet, pull the right of lower sewing machine needle of transferring again with connecting rod and rotating shaft etc., suture is pulled up by the bending steel wire on the right etc. after sewing finishing, such wire drawer manufacturing cost height complex structure, volume is large affects working space and visual angle, the most terribly that bending steel wire pin on the right of eedle can hook sewing when can affect real work, when pulling out line, workman's hand formula is to also getting to staff, or debugs and not in placely also interrupt the problems such as eedle.
For the problems referred to above, China Patent No. is 201220193978.0, and the utility model patent that name is called " the playing suture head controlling device of a kind of Sewing machines " proposes the improved device of these parts.Its technical scheme adopted is, above the eedle of head of sewing machine bottom, configure three directions be all bent into the support that upwards, right angle is dustpan-shaped, wherein back upwards extends, and offers circular hole, and support is fixed on head by screw; The front of support arranges T-shaped clamp head, and wherein in opposite directions, the depression bar handle that T-shaped clamp head is vertical with pressing plate penetrates the front of support, is coaxial docking with the adhesive electromagnet be configured on the circular hole of support back the rectangular platen of T-shaped clamp head and front; Adhesive electromagnet has two states, and when energized, the depression bar handle of T-shaped clamp head backward or mobile, fit, and when power is off, the depression bar handle of T-shaped clamp head moves forward, and pressing plate is separated with front by pressing plate and front; Adhesive electromagnet controls energising or power-off by computer.When industrial sewing machine plays seam, eedle works downwards, play the energising of suture head controlling device, the depression bar handle of T-shaped clamp head backward or mobile, fit in pressing plate and front, playing suture head is clamped between pressing plate and front, control suture head not elongated by eedle, left over rotating shuttle ditch line below the end of a thread beyond on eedle to sewing when eedle continues down to move just to take away to make last time and lock knot, reached and made the end of a thread when stitching and return below sewing.When eedle gets back to extreme higher position, play the power-off of suture head controlling device, the depression bar handle of T-shaped clamp head moves forward, and pressing plate is separated with front and does not clamp, and enters and commonly makes not clamp state.
But technique scheme is very high to the processing request of element precision, if the processing of part can not meet the requirements of words, easily cause clamp problem loosely.The gripping action of adhesive electromagnet by driving depression bar handle to control T-shaped clamp head in such scheme, the adhesive axle of adhesive electromagnet has former and later two limit of sports record positions, when energized, motion after adhesive axially, when moving to rear extreme position, T-shaped clamp head ability clamping lines, require very high to the length accuracy of depression bar handle, the length of depression bar handle is long, can cause the situation can not clamping line completely, the length of depression bar handle is too short, and adhesive axle can be caused can not to move to rear extreme position, make the suction-combining force inadequate, clamp loosely.And also can be caused clamp situation loosely by the thickness of clamp, line is too thin, can cause the situation can not clamping line completely, and line is too thick, and adhesive axle can be caused can not to move to rear extreme position, and make the suction-combining force inadequate, clamp loosely.
Utility model content
In view of the above problems, what the utility model proposes a kind of Sewing machines through improvement plays suture head controlling device, can come suitably to adjust, ensure the firm of clamp according to the error existed in the thickness of line and part processing.
To achieve these goals, the technical solution adopted in the utility model is: a kind of sewing machine thread head controlling device, comprise the installing plate being horizontally placed on head of sewing machine lower end, described installing plate front end arranges wire-clamping device, rear end arranges adhesive electromagnet, and connect the push rod of wire-clamping device and adhesive electromagnet, described push rod and adhesive electromagnet link and arrange, it is characterized in that: described wire-clamping device comprises the quiet clamping plate being fixedly installed on installing plate front end and the dynamic clamping plate arranged in opposite directions with quiet clamping plate, described dynamic clamping plate and the hinged setting of quiet clamping plate; Described dynamic clamping plate one end and quiet clip board engagement clamp, the other end abuts with the front end face of push rod; Quiet clamping plate are arranged the return spring that clamping plate are separated with it; Described dynamic clamping plate are arranged the adjusting device regulating dynamic clamping plate and push rod spacing.
The utility model is arranged further, and described adjusting device is be arranged at the adjusting bolt on dynamic clamping plate, and described dynamic clamping plate arrange the screwed hole corresponding with push rod, and adjusting bolt abuts with push rod front end face through this screwed hole.
The utility model is arranged further, and described return spring is the Compress Spring arranged near clamp end, and quiet clamping plate arrange spring base, and described Compress Spring one end is connected to spring base, and the other end abuts with dynamic clamping plate.
By adopting technique scheme, dynamic clamping plate arrange the adjusting bolt corresponding with push rod, when institute's clamp is crossed thick, the adhesive axle of adhesive electromagnet can not adhesive completely, causes the suction-combining force inadequate, make to clamp not strongly, at this moment, by outwards screwing out adjusting bolt, compensating because line crosses thick and causing the adhesive axle of adhesive electromagnet can not the gap of adhesive completely, make the complete adhesive of adhesive axle of adhesive electromagnet, ensure the firm of clamp; When institute's clamp is meticulous, the situation can not clamping line completely can be caused, dynamic also exist the surplus brought because line attenuates between clamping plate and quiet clamping plate, at this moment, by inside precession adjusting bolt, compensate the surplus gap of bringing because line attenuates, make clamping plate and quiet clamping plate clamping lines, ensure the firm of clamp; And push rod exists long or too short error because of processing, also regulate by adjusting bolt.
