Description

The computer quilting embroidery machine change width of cloth device

Technical field:

The utility model belongs to sewing device, and particularly computer quilting embroidery machine lining changes the improvement of width of cloth mechanism.

Background technology:

Existing computer quilter is in the process to whole cloth quilting, in order to make the lining tensioning so as embroidery, each frame at its frame that stretches tight is shaped on convex compress rail, after will lining be embroidered spreading, the female clip cloth that will cooperate with convex compress rail clamps (as shown in Figure 4) with lining at four frames by hand.After paper web embroidery is finished, take off the folder cloth by the workman, will embroider the breadth volume and move, do not repeat to clamp to embroidering breadth again.Since change the width of cloth by hand, the one, influence efficient, the 2nd, the instability of the tensioning application of force by hand causes the lining out-of-flatness and influences the embroidery quality.

Summary of the invention:

The purpose of this utility model is can move width of cloth device certainly by the lining of machine dispensing computer control for the computer quilting embroidery machine provides a kind of.

The utility model comprises by X and to the frame that stretches tight that two frames and Y form to two frames convex compress rail to be housed respectively on every frame, it is characterized in that each convex compress rail top is equipped with concavo-convex that cooperate and by the Pneumatic elevation spill cloth clamp bar of computer control with it respectively.Spill cloth clamp bar top is connected with cylinder piston rod respectively.Every long frame edge is equipped with 4～10 Y at interval to Pneumatic elevation spill cloth clamp bar, and every broadside is equipped with 2～3 X to Pneumatic elevation spill cloth clamp bar.

Above-mentioned each X of frame both sides that stretches tight is connected with the cylinder piston rod pivot pin by a door shape connecting rod to Pneumatic elevation cloth clamp bar, and a shape connecting rod side lower end is connected with the underframe pivot pin, and the piston rod pivot pin is positioned at the underframe pivot pin) corner of a side door shape connecting rod.Each X also is equipped with X to the clamping cylinder below and strains cylinder to cloth, and its piston rod is connected with underframe.

The utility model is provided with a plurality of cylinders on the frame frame that stretches tight, utilize computer program control cylinder piston rod, respectively X, the Y direction of lining are tightened and actions such as Song Jia, go up material embroidery place location, pre-air cylinder opposite, the preceding pre-cylinder that clamps clamps lining, to avoid lining displacement in changing width of cloth process, thereby realize from moving width of cloth operation, both can enhance productivity, because computer is controlled the constant of chucking power, make the lining even tension again, the breadth junction is indeformable does not slide, help breadth junction embroidery continuous pattern, guaranteed the quality of embroidery.

The specific embodiment:

With reference to the frame that stretches tight shown in Figure 1, the actual installation direction is turned left 90 ° for Fig. 1.The rectangle frame that stretches tight is made up of two long margin frames 3 (Y to), two minor face frames 4 (X to), equidistantly at interval on each long margin frame a plurality of Y is installed to clamping cylinder 1, and quantity decide on the frame length that stretches tight, and the present embodiment frame is grown 5.7 meters, and then number of cylinders is 8.Cylinder 1 is incorporated with the cylinder frame 2 of the section bar formation of square-section.

With reference to Fig. 2, Y passes below cylinder frame 2 section bars to clamping cylinder piston rod 5, its bottom is connected by metal crimp cloth 6 and female clip cloth 8, and the section bar convex compress rail 7 that a side has " Ω " tee section is equipped with in its below, " Ω " shape convex compress rail 7 can with 8 concavo-convex cooperations of female clip cloth.Connecting plate 10 upper and lower sides are connected cylinder frame 2 and frame 3 respectively with convex compress rail 7, bolt 9 be used for above-mentioned three layers fixedly connected.

With reference to Fig. 3, be loaded on minor face frame 4 two ends be equipped with up and down respectively X to clamping cylinder 15 and X to tension cylinder 16.The piston rod 14 of cylinder 15 is connected with axle 13 with the near-end turning of door shape connecting rod 12, door shape connecting rod 12 front bottom end are equipped with spill cloth clamp bar 11, the section bar convex compress rail 21 that a side has " Ω " tee section also is equipped with in its below, and with 11 concavo-convex cooperations of spill cloth clamp bar.The pivot pin 18 of bottom, door shape connecting rod 12 rear ends is connected with underframe 19, and convex compress rail 21 is connected by screw 20 and underframe 19, thereby makes underframe 19, convex compress rail 21, door shape connecting rod 12 connect into integral body.X is connected with underframe 19 to the piston rod 17 of tension cylinder 16.

Represented among Fig. 5 to be provided with front clamp bar 25 at platen 29 front ends.See that from Fig. 6, Fig. 7 etc. the head sidewall 27 of 2 heads in every interval connects upward pre-air cylinder 22 among the head group, direction is perpendicular to platen 29, and its piston-rod lower end connects a compress piece 23.

With reference to Fig. 8, Fig. 9, pre-air cylinder 24 before below platen 29 forward positions, at interval several being housed, direction is parallel to platen 29, and compress piece 26 is equipped with on its piston rod top, fix a clamping bar 25 with respect to each compress piece 26 anterior position, lining can be clamped between each compress piece 26 and clamping bar 25.

Change width of cloth process:

Sequence of movement when paper web embroidery finishes to begin to change the width of cloth is:

1, preceding pre-clamping cylinder 24 is pushed down lining with last pre-air cylinder 22 inflations;

2, X unclamps to tension cylinder 16 to clamping cylinder 1 and X to clamping cylinder 15, Y;

3, the frame that stretches tight moves backward to desired location;

4, Y pushes down lining to clamping cylinder 1 inflation;

5, X pushes down lining to clamping cylinder 15 inflations by connecting rod 12;

6, X makes lining smooth at directions X to tension cylinder 16 inflation tension linings;

7, unclamp preceding pre-cylinder 24 and the last pre-air cylinder 22 of clamping, begin the embroidery of next paper web.

More than the action that moves forward and backward of each cylinder and batching axle and the frame that stretches tight by machine dispensing computer 30 by the control of designing program, can keep changing the accurate butt joint of lining junction before and after the width of cloth.
