Description
Technical field
The present invention relates to special-purpose sewing device, refer to a kind of chain type bead edging machine of making imitative handmade finish stitching especially, specifically refer to the improvement that pushes away the line bending needing mechanism the chain type bead edging machine.
Background technology
Recently apparel industry is praised highly the stitching made from a kind of craft, be similar to the pearl pelletron and is made senior dress ornament, as the decoration linear slit of the limit portion of Western-style clothes, overcoat etc.So a kind of energy forms the single-line chains chain stitch sewing machine that is similar to hand stitch, promptly the chain type bead edging machine arises at the historic moment.This bead edging machine cost is low, production efficiency is high, and the front of stitching is fully the same with manual stitching, is subjected to the welcome of apparel industry.But because this bead edging machine is when forming the single-line chains stitching, single line will be through 4 pins, be staight needle, straight crochet hook, hook line looper and push away cooperatively interacting of line looper, the effect that wherein pushes away the line bending needing mechanism is the position of the wire loop of staight needle and the formation of hook line looper being shifted onto straight crochet hook, straight crochet hook can successfully be hooked wire loop, to form stitching.In the prior art, the line bending needing mechanism that pushes away of bead edging machine generally all adopts horizontally disposed secondary transmission to finish the motion of the directions X that pushes away the line looper, and the schematic diagram of its driving-chain as shown in Figure 1.In this driving-chain, the rotation of lower shaft 11 is by eccentric wheel 10 and a spherical connecting bar 101, two 102,104 and long connecting rods 103 of wobble crank cooperating of totally 6 axis holes, just finishes the swing that pushes away line looper 14 and pushes away line and move.Because this mechanism driving chain length, points of engagement is many, and machine weares and teares easily in running up, and generation is loosening, makes the machine works instability, and the bouncing pilotage rate improves, and noise increases, and also makes the adjustable range of machine dwindle degradation simultaneously.
Summary of the invention
What the objective of the invention is to propose a kind of improved chain type bead edging machine pushes away the line bending needing mechanism, this mechanism changes the secondary kind of drive of traditional horizontal layout, in limited space, by eccentric wheel is moved on to an end of lower shaft from the centre of lower shaft, and change connecting rod into vertical layout with parts such as pushing away the line curved needle seat by horizontal layout, like this as long as by the one-level transmission, just can finish and push away the line looper and push away the line action in the swing of directions X, thereby reduce mechanically operated link, reduce wear and noise, the stability of raising equipment, and reduce the number of spare parts of equipment and reduce manufacturing cost.
A kind of chain type bead edging machine of the present invention push away the line bending needing mechanism, mainly comprise a lower shaft 11, one eccentric wheel 10, one connecting rod 9, one ball crank 8, one T junction 5, one fork 13, one pushes away line curved needle seat 15, one pushes away line looper 14, described eccentric wheel 10 is solidly set on an end of lower shaft 11, its eccentric part and connecting rod 9 one ends articulate, the other end of connecting rod 9 and ball crank 8 articulate, the directions X of the other end of ball crank 8 and T shape swing span is connected, fork 13 is solidly set on the Y direction of swing span, pushes away line curved needle seat 15 and is fixed on the fork 13, pushes away line looper 14 and is fixed in and pushes away on the line curved needle seat 15.
Described connecting rod 9 vertically is provided with along the Z direction, its upper end articulates with eccentric eccentric part 10a, and its lower end articulates with ball crank 8, describedly pushes away also vertical (along the Z direction) setting of line curved needle seat 15, its lower end and fork 13 are connected, and push away line looper 14 and are fixed in the upper end that pushes away line curved needle seat 15.By such processing, became one-level transmission in the space that is arranged in a solid with being arranged in secondary transmission in the same plane originally.
The present invention compares with the line bending needing mechanism that pushes away of original secondary transmission, and new mechanism has only a connecting rod, a ball crank, 3 axis hole points of engagement, structure simplifies greatly, and part has almost reduced half, adjusts more convenient, adjustable range enlarges, and move more stablely, and the while has also been reduced manufacturing cost; Because driving-chain is short, the axis hole points of engagement reduces, it is little to load, and the wearing and tearing of equipment are also corresponding to be reduced, even if under the identical situation of wear extent, causes the play that pushes away the line looper also to reduce; Because have only one group of reciprocating motion, mechanical shock has reduced, and has reduced the work noise of equipment.In sum, new mechanism simple in structure, easy to adjust, adjustable range is big, wear and tear little, noise is little, the bouncing pilotage probability is low, moves more stable.
Description of drawings
Fig. 1 is the driving-chain schematic diagram of prior art;
Fig. 2 is the structural representation of one embodiment of the present of invention.
Among the figure: 1 staight needle bar, 2 staight needle seats, 3 staight needles, 4 straight crochet hooks, the 5T Y joint, 6 hook line loopers, 7 hook line curved needle seats, 8 ball cranks, 9 connecting rods, 10 eccentric wheels, 11 lower shafts, 12 bearings, 13 forks, 14 push away the line looper, and 15 push away the line curved needle seat, 16,17 linings.
The specific embodiment
Now the invention will be further described in conjunction with an embodiment and accompanying drawing thereof.
By Fig. 2, eccentric wheel 10 is solidly set on an end of lower shaft 11, the upper end of its eccentric part and vertically disposed connecting rod 9 articulates, the lower end of connecting rod 9 and ball crank 8 articulate, the directions X hole 8a of the other end of ball crank 8 and T junction 5 is connected, and fork 13 is hubbed in the axis hole of bearing 12, and the one end is fixed among the Y direction hole 8b of T junction 5, push away line curved needle seat 15 also vertical fixing push away 14 of line loopers and be fixed in and push away line curved needle seat 15 upper ends in the other end of fork 13.
Described fork 13 is hubbed on the bearing 12, and this bearing is fixedly arranged on the frame of bead edging machine.Described bearing 12 is provided with two axis holes, is provided with a lining 16 or 17 in each axis hole, and described fork 13 is hubbed in this lining.
When rotating under the drive of lower shaft 11 in main transmission, be located at toggle and T junction 5 that the eccentric wheel 10 on the lower shaft 11 is formed by connecting rod 9, ball crank 8, make with the fork 13 of 11 one-tenth 90 ° of lower shafts and swing around its axis, and make the line curved needle seat 15 of pushing away that is fixed on this fork 13 drive and push away line looper 14 and swing along directions X, finish the swing that pushes away line looper 14 and push away the line action.As seen from the figure, lower shaft 11 is just finished the transmission that pushes away the action of line looper only by 9, one ball cranks 8 of a connecting rod and 3 axis hole points of engagement.
