Description
Affiliated technical field
The utility model relates to the middle wire-threading device on the computerized emboridering machine shank device, the structure and the installation site of crossing the line parts of especially middle wire-threading device.
Background technology
Because embroidery machine is the line that utilizes various different colours pattern is embroidered on textiles,, and be included in syringe needle among each pin folder and all worn line with different colours so each sewing device all contains six to 12 pins folders.Wire-threading device during the line of various different colours must pass through from the coil holder to the syringe needle.Wire-threading device is L shaped cuboid in existing, wherein cross line plate (vertically plate) and be provided with several cable-through holes, porcelain ring (being cable-through hole hereinafter to be referred as " cable-through hole of porcelain ring is installed ") is installed in the cable-through hole, the porcelain Overline ring perpendicular to vertical plate is installed between adjacent two cable-through holes.The weak point of wire-threading device is that floss silk breaks easily in existing, reason is that this section camber line of floss silk process cable-through hole-Overline ring-cable-through hole approaches straight line, because the lateral separation between Overline ring and the cable-through hole is far longer than fore-and-aft distance, that is to say that the contact-making surface of floss silk and cable-through hole and Overline ring is not slick and sly.Although the material of Overline ring and cable-through hole is a porcelain, have smooth performance,, the cellulosic floss silk that moves directly contacts with Overline ring with the cable-through hole of fixed porcelain, produces sliding friction, and the outage of floss silk is bigger.
Summary of the invention
In order to overcome existing middle wire-threading device because unreasonable structure causes the floss silk deficiency of broken string easily, the utility model provides a kind of can reduce outage and middle wire-threading device easy for installation.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of middle wire-threading device of computerized emboridering machine, comprise line and be somebody's turn to do the middle cable-through hole of crossing on the line, design feature: the one, be provided with and cross line in the groove shape cuboid, should middlely cross line is made of bottom land, front side plate and back side panel, this bottom land is provided with several circular cable-through holes, this front side plate is provided with cap, and this back side panel is provided with the pin hole.The 2nd, be provided with several rollers, each roller is positioned between cap and the pin hole, and perpendicular to back side panel.The 3rd, be provided with and cross the line seat in the step, the plate of topping bar of crossing the line seat in this connects with the middle back side panel of crossing line, and the plate of getting out of a predicament or an embarrassing situation of crossing the line seat in this is fixed on the bottom of needle bar frame top panel.According to this technical scheme, because the vertical range between the cable-through hole of roller and its both sides is enough big, make floss silk only be attached on the periphery of roller and do not contact with the cable-through hole inner face, operating floss silk drives roller and rotates between cap and pin hole, friction between floss silk and the roller belongs to rolling friction, force of rolling friction is far smaller than force of sliding friction, so can reduce outage.Because middle line seat excessively is a step, upper and lower stepped plate can connect with relevant parts respectively, and is very convenient.
Wire-threading device in described, its design feature is to be provided with the rectangle window between two adjacent described cable-through holes.Roller faces this rectangle window.This structure helps observing the running status of floss silk.
Wire-threading device in described, its design feature is that two end faces of described roller are smooth protruding curved surface.Can adopt smooth convex lens.Can also adopt smooth sphere.This structure guarantees that roller operates steadily, and reduces resistance as far as possible, makes floss silk with smaller frictional force roller be rotated, and prevents broken string.
Wire-threading device in described, its design feature are the center of circle of the axis of described roller by described cap and pin hole.This structure and roller end face structure complement each other.
The beneficial effects of the utility model are, because roller can rotate, only have rolling friction between floss silk and the roller, can significantly reduce outage, have solved user's difficulty, have improved the production efficiency of embroidered article greatly.

The specific embodiment
As shown in Figure 5, wire-threading device is made up of middle line 1, roller 8 and middle line seat 9 three parts of crossing crossed in the utility model computerized emboridering machine.
As depicted in figs. 1 and 2, the middle line 1 of crossing is by bottom land 2, front side plate 4 and back side panel 6 one-body molded (referring to Fig. 5, Fig. 6, Fig. 7).
As shown in Figure 1, bottom land 2 is provided with several circular cable-through holes 3, and the quantity of cable-through hole 3 equates with the quantity of embroidery machine syringe needle.In Fig. 1, the quantity of cable-through hole 3 is 12.
As shown in Figure 1, front side plate 4 is provided with cap 5, and these cap 5 interior shapes and roller 8 upper end shapes adapt.
As Fig. 2, shown in Figure 6, back side panel 6 is provided with pin hole 7, and these pin hole 7 actinal surface shapes and roller 8 lower surface shapes adapt.
As shown in Figure 4, roller 8 is a cylinder, and two end face 14 is smooth protruding curved surface, and this curved surface can be that convex lens also can be a sphere, and the utility model adopts sphere.
As shown in Figure 5, each roller 8 is positioned between cap 5 and the pin hole 7, and perpendicular to back side panel 6, the parts manufacturing technique has guaranteed the center of circle of the axis of roller 8 by described cap 5 and pin hole 7.
As shown in Figure 5, the plate 10 of topping bar of mistake line seat 9 is linked together (plates 10 of topping bar in back side panel 6 coverage diagrams 3 among Fig. 2) with the middle back side panel 6 of crossing line in the step.The middle plate 11 of getting out of a predicament or an embarrassing situation of crossing the line seat is fixed on the bottom of needle bar frame top panel 12.
As shown in Figure 1, be provided with rectangle window 13 between two adjacent cable-through holes 3, the roller 8 among Fig. 5 faces on the bottom land 2 window 13 between two cable-through holes 3.
Have rolling friction between the periphery of the roller 8 among Fig. 5 and the floss silk, the parts manufacturing technique has guaranteed that roller 8 is with as far as possible little frictional force moving and roll (rotation) along with floss silk.Contribution of the present utility model is: in the time of on the known wire-threading device of floss silk process, be sliding friction between floss silk and the Overline ring; And floss silk is through on the utility model wire-threading device time, is rolling friction between floss silk and the middle mistake line roller.The utility model is changed into rolling friction with sliding friction, has just reduced frictional force, has also just reduced outage.
