Abstract
The invention discloses a high-speed single needle bar drive head which comprises a housing and a head assembly in the housing. The head assembly is mounted on a main beam of a quilting embroidery machine, a transmission main shaft is arranged on the quilting embroidery machine, and a plurality of driving gears are mounted on the transmission main shaft. The head assembly comprises a driven gear, a driving crank, a needle bar crank, a jumper bar, a needle bar connecting rod, a sliding block frame, a connection shaft, a guide rod, a sliding block (A), a sliding block (B), an electromagnet frame (A) and an electromagnet frame (B), and two electromagnets are correspondingly arranged beside the sliding block (A) and the sliding block (B) and are respectively mounted on the electromagnet frame (A) and the electromagnet frame (B). The high-speed single needle bar drive head has the advantages that when the electromagnets work, the ends of the sliding blocks are blocked by electromagnet blocking members and then the sliding blocks rotate around sliding block pins, so that U-shaped grooves on the opening portions of the sliding blocks can be separated from a connecting shaft on the needle bar to enable the needle bar to stop working; and when the electromagnets does not work, the sliding blocks move to the original positions under the action of torsion springs.
Description
Technical field
The present invention relates to a kind of embroidering machine head, particularly relate to a kind of high speed single needle bar drive head being mainly used in the quilting and embroidering integrated machine of the industry fabric panel pattern design processing such as family is spun, clothes, house ornamentation, car dress.Belong to the stitch machine technical field in light industry special equipment.
Background technology
Along with the renewal of people's consumption idea and the lifting of aesthetic standard, in recent years, the requirement that the industries such as family is spun, clothes sew with long stitches embroidery processing to fabric panel pattern design is more and more higher, comprise operating characteristics, the scope of application, production capacity etc., need constantly to release meet market development demand sew with long stitches embroidery process equipment.Thus challenge is had more to the technical merit of embroidering machine, not only need quilting and embroider disposablely to complete, more need that performance is excellent, function is complete, automaticity is high, purposes is wide, output is high, easy to operate, safe and reliable sews with long stitches embroidery process equipment.
Head is the core work parts of embroidering machine, and the shank of head moves up and down and the wire jumper motion of wire jumper bar decides the hook correctness of line and accordance, the accuracy of stitching.Disclosed " quilting and embroidering integrated machine head " patent is that two shanks must work simultaneously, and can not close arbitrarily arbitrary shank and carry out selective use, adaptability is not strong.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Summary of the invention
The object of this invention is to provide a kind of superior performance, the high speed single needle bar drive head that rational in infrastructure, easy to operate, rotating speed is high.
The technical solution used in the present invention is:
High speed single needle bar drive head, comprise the head assembly in casing and casing, described head assembly is installed on the crossbeam of embroidering machine, transmission line shaft embroidering machine is equipped with, described transmission line shaft is provided with multiple driving gear, this head assembly comprises driven gear, driving crank, needle bar crank, wire jumper bar, shank connecting rod, slider frame, connecting axle, guide post, slide block A, slide block B, electromagnetism brandreth A and electromagnetism brandreth B, described driving gear engages with driven gear, described driven gear is loaded on wire jumper camshaft, described wire jumper camshaft drives driving crank to rotate, described driving crank drives shank link motion by needle bar crank, described driving crank drives wire jumper bar to do wire jumper motion by needle bar crank, described shank connecting rod lower end is arranged on slider frame, described slider frame both sides are separately installed with guide post, each guide post is connected with shank by connecting axle, described shank is fixed in needle bar frame, described slide block A and slide block B are installed on slider frame respectively, described slide block A and slide block B side correspondence are provided with electromagnet, two electromagnet are installed on electromagnetism brandreth A and electromagnetism brandreth B respectively.
Two connecting axles be connected on shank embed in the U-type groove of slide block A and slide block B oral area respectively.
Described slide block A and slide block B are fixed on slider frame by slide block bearing pin, and described slide block bearing pin is provided with torsion spring.
Beneficial effect of the present invention: when work of electromagnet, electromagnet stopper blocks the afterbody of slide block, makes it rotate around slide block bearing pin, causes the connecting axle on the U-type groove disengagement shank of slide block oral area, shank is not worked; When electromagnet does not work, slide block resets under the effect of torsion spring.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As illustrated in fig. 1 and 2, high speed single needle bar drive head of the present invention, comprise the head assembly in casing 1 and casing 1, head assembly is installed on the crossbeam 17 of embroidering machine, transmission line shaft 2 embroidering machine is equipped with, transmission line shaft 2 is provided with multiple driving gear 3, this head assembly comprises driven gear 4, driving crank 6, needle bar crank 7, wire jumper bar 9, shank connecting rod 8, slider frame 10, connecting axle 12, guide post 13, slide block A11, slide block B 18, electromagnetism brandreth A14 and electromagnetism brandreth B15, driving gear 3 engages with driven gear 4, driven gear 4 is loaded on wire jumper camshaft 5, wire jumper camshaft 5 drives driving crank 6 to rotate, driving crank 6 drives shank connecting rod 8 to move by needle bar crank 7, driving crank 6 drives wire jumper bar 9 to do wire jumper motion by needle bar crank 7, shank connecting rod 8 lower end is arranged on slider frame 10, slider frame 10 both sides are separately installed with guide post 13, each guide post 13 is connected with shank 19 by connecting axle 12, shank 19 is fixed in needle bar frame 20, slide block A11 and slide block B 18 are installed on slider frame 10 respectively, slide block A11 and slide block B 18 side correspondence are provided with electromagnet 21, two electromagnet 21 are installed on electromagnetism brandreth A15 and electromagnetism brandreth B15 respectively.
Two connecting axles 12 be connected on shank 19 embed in the U-type groove 22 of slide block A11 and slide block B 18 oral area respectively.
Slide block A11 and slide block B 18 are fixed on slider frame 10 by slide block bearing pin 23, slide block bearing pin 23 are provided with torsion spring 16.
When electromagnet 21 works, electromagnet 21 stopper blocks the afterbody of slide block, makes it rotate around slide block bearing pin 23, causes the U-type groove 22 of slide block oral area to throw off connecting axle 12 on shank 19, shank 19 is not worked; When electromagnet 21 does not work, slide block resets under the effect of torsion spring 16.
Head shank 19 moves up and down and the wire jumper motion of wire jumper bar 9 decides the hook correctness of line and the accuracy of stitching, change the deficiency that former two shanks 19 move perhaps simultaneously, single shank 19 drive, and the selective use in pin position can be carried out easily, strong adaptability, this driving head superior performance, rational in infrastructure, easy to operate, rotating speed is high.
