Abstract
The utility model provides a needle stretching tight mechanism that can decorate sewing for double sides. The mechanism is fixed and connected by a lower axis driven by a pulley and a spherical eccentricity cam. The spherical eccentricity cam is connected with the lower end of a long haff connecting rod in a sliding way. The long haff connecting rod is connected with a rocker of an upper axis through a connecting rod pin in a pinned way. The stretching tight needle is fixed at the lower end of the stretching tight needle axis; the rocker of the upper axis is fixedly connected with the upper axis spherical dog, while the upper spherical hole of the stretching tight needle haff connecting rod is connected with the upper axis rocker spherical dog sphere; the lower spherical hole of the stretching tight needle haff connecting rod is connected with the stretching tight needle spherical dog sphere. The utility model has three needles and five threads function, which enables the formed thread traces to be more beautiful, stable with stable qualities.
Description
Technical field:
The utility model relates to the improvement of the pin mechanism of stretching tight of a kind of sewing mechanical equipment, particularly flat seaming machine.
Background technology:
At present, the three pin flat seaming machines of selling on the domestic and international market can only carry out the single face ornamental seam, and a pattern is attractive in appearance, and another side is simple stitching, and pattern is succinct, can not be as ornamental seam, and also the flat-seam firmness is poor.
Summary of the invention:
The purpose of this utility model provides a kind of pin mechanism of stretching tight that can carry out two-sided ornamental seam.
The utility model is fixedlyed connected with the sphere eccentric cam by the lower shaft that belt pulley drives, long Hough connecting rod lower end and sphere eccentric cam are rotatably connected, the axle rocking bar connects by the link pin pin on the upper end, the pin that stretches tight is horizontally fixed on the needle shaft lower end of stretching tight, it is characterized in that: go up the axle rocking bar and fixedly connected with last axle sphere dog, the stretch tight last ball hole of pin Hough connecting rod is connected with last axle rocking bar sphere dog sphere, the stretch tight following ball hole of pin Hough connecting rod is connected with the pin sphere dog sphere that stretches tight, and the other end of the pin sphere dog that stretches tight is solidly set on the needle shaft axostylus axostyle that stretches tight.Pin sphere dog and stretch tight and between the pin Hough connecting rod cap thread tension spring is arranged stretches tight.
Pin mechanism has three pins and colludes the line function because stretch tight, and can carry out two-sided ornamental seam, makes five line stitchings of formation more attractive in appearance, firm, more stable quality.
Description of drawings:
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is a vertical view of going up axle rocking bar part among Fig. 1.
The specific embodiment:
With reference to accompanying drawing, belt pulley 5 is fixedlyed connected by following wheel disc pin 6 screws 23 with lower shaft 9, lower shaft 9 is fixedlyed connected by trip bolt 27 with sphere eccentric cam 8, sphere eccentric cam 8 is automatically connected in long Hough connecting rod 3 lower ends, long Hough connecting rod 3 is sold by long Hough link pin 2 with last axle rocking bar 1 and is connected, and stretch tight needle shaft 21 and the level pin 20 that stretches tight is fixedlyed connected.Last axle rocking bar 1 is fixedlyed connected with last axle sphere dog 12, the stretch tight last ball hole of pin Hough connecting rod 13 cooperates with last axle rocking bar sphere dog 12 spheres, the stretch tight following ball hole of pin Hough connecting rod 13 cooperates with pin sphere dog 17 spheres that stretch tight, stretch tight pin sphere dog 17 and stretch tight and be with thread tension spring 22 between the pin Hough connecting rod cap 14, stretch tight pin sphere dog 17 be solidly set on the shaft of the needle shaft 21 that stretches tight.When belt pulley 5 rotations, drive sphere eccentric cam 8 and rotate.Eccentric cam makes the reciprocating motion of long Hough connecting rod, goes up 1 swing of axle rocking bar thereby drive, and last axle rocking bar 1 is fixedlyed connected with last axle sphere dog 12, thereby goes up a rocking bar sphere dog 12 and swing simultaneously.Drive pin Hough connecting rod 13 swing of stretching tight, the pin Hough connecting rod 13 that stretches tight drives pin sphere dog 17 swings of stretching tight, and the needle shaft 21 that stretches tight is produced back and forth rotate.The pin 20 that stretches tight is fixed on the pin draft link 18 that stretches tight, and the pin draft link 18 that stretches tight is fixed on the needle shaft 21 that stretches tight.When needle shaft 21 back and forth rotated because stretch tight, the feasible pin 20 that stretches tight produced and the synchronous level left and right sides reciprocally swingings of shank.Catch on the pin suture that stretches tight when the pin 20 that stretches tight moves to rightmost, and drive suture to left movement, link with the staight needle suture during to Far Left, the pin that after this stretches tight is swung to the right, tightens up stitching, the needlework mark thereby realization is stretched tight.
