Abstract
The utility model discloses a mechanism for adjusting the wire loop size of an industrial multi-needle sewing machine, which comprises a driving motor for supplying power, wherein a driving spindle is in transmission connection with a needle bar crank mechanism through an eccentric mechanism; the lower side of the eccentric mechanism is connected with a thread take-up lever mechanism through a ball joint; a plurality of threading holes are formed in parallel on the thread take-up lever mechanism; the needle bar crank mechanism is sleeved with a needle bar connecting rod; the needle bar connecting rod is connected with a needle bar through a needle bar connecting column; the upper end of the needle bar is provided with a needle bar leading wire mechanism provided with a plurality of threading holes; the lower end of the needle bar is provided with a needle clamp provided with a plurality of needles; and a suture passes through a thread take-up lever, the needle bar leading wire mechanism, the needle clamp and the threading holes on the needles in turn. The mechanism for adjusting the wire loop size of the multi-needle sewing machine has a simple structure and is convenient to adjust the size of wire loops.
Description
Technical field
The utility model relates to a kind of governor motion, is specially the mechanism that a kind of industrial multineedle sewing machine is regulated the wire loop size.
Background technology
As Sewing machines, finish the sewing function, the eedle line must form the wire loop that a size is fit to, so that make looper (bearded needle) can catch on the eedle line smoothly, wire loop is too greatly, the too little bearded needle that all can make colludes less than line.The too little easy line of wire loop is tight, and the excessive bouncing pilotage that more is easy to generate of wire loop wants comprehensive actual conditions to determine the size of required wire loop, and the wire loop that thin material forms is less, and the wire loop that thick material forms is bigger.
The solution of tradition Sewing machines wire loop size is to increase a shank lead on the shank next door, the height of metering needle rod guidance line is regulated the wire loop size, but the method is little to the effect of wire loop size control, but also can increase the defeated line amount of eedle line, from and influence the sewing performance of complete machine.
The utility model content
The purpose of this utility model is in order to provide a kind of industrial multineedle sewing machine to regulate the mechanism of wire loop size, to solve the problems referred to above of prior art.
The purpose of this utility model can be achieved through the following technical solutions.
A kind of industrial multineedle sewing machine is regulated the mechanism of wire loop size, and it comprises the drive motors that power is provided, and is in transmission connection by eccentric stiffener between driving main shaft and the needle bar crank mechanism; The below of eccentric stiffener is connected with thread take-up tension lever mechanism by spherojoint, and thread take-up tension lever mechanism level is also shown some through wires holes; Be arranged with the shank connecting rod in the needle bar crank mechanism, the shank connecting rod is connected with shank by the shank joint pin; The upper end of shank is provided with the shank conducting mechanism that has some through wires holes, and the lower end of shank is equipped with the pin folder that has some eedles; Suture passes the through wires hole on thread take-up tension lever, shank conducting mechanism, pin folder and the eedle successively.
Described thread take-up tension lever mechanism, shank conducting mechanism and needle stand horizontal positioned.
Described eccentric stiffener comprises off-centre and eccentric ratio.
The utility model is regulated the size that wire loop can be controlled in eccentric phase angle.
The multineedle sewing machine that designs by the utility model is regulated the mechanism of wire loop size, and is simple in structure, the size of being convenient to regulate wire loop.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1, main shaft 2, eccentric ratio 3, off-centre 4, needle bar crank mechanism 5, shank conducting mechanism 6, spherojoint 7, thread take-up tension lever mechanism 8, shank connecting rod 9, shank 10, shank joint pin 11, pin folder 12, eedle.
The specific embodiment
Further set forth design feature of the present utility model below in conjunction with accompanying drawing and specific embodiment.
A kind of industrial multineedle sewing machine is as shown in Figure 1 regulated the mechanism of wire loop size, and it comprises the drive motors that power is provided, and is in transmission connection by eccentric stiffener between driving main shaft 1 and the needle bar crank mechanism 4; The below of eccentric stiffener is connected with thread take-up tension lever mechanism 7 by spherojoint 6, and thread take-up tension lever mechanism 7 levels are also shown some through wires holes; Be arranged with shank connecting rod 8 in the needle bar crank mechanism 4, shank connecting rod 8 is connected with shank 9 by shank joint pin 10; The upper end of shank 9 is provided with the shank conducting mechanism 5 that has some through wires holes, and the lower end of shank 9 is equipped with the pin folder 11 that has some eedles 12; Suture passes the through wires hole on thread take-up tension lever mechanism 7, shank conducting mechanism 5, pin folder 11 and the eedle 12 successively.Described eccentric stiffener comprises off-centre 3 and eccentric ratio 2.
Under the stopped status, eedle 12 is at peak; Eccentric 3 phase place hysteresis needle bar crank 4 is positioned at certain angle mutually.
Rotating spindle 1, needle bar crank mechanism 4 drives shank connecting rod 8 driving shanks 9 and moves downward, the rotation of main shaft 1 simultaneously also makes eccentric 3 drive eccentric ratios 2, spherojoint 6 make thread take-up tension lever mechanism 7 to lower swing, when eedle 9 moves downward to minimum point because the phase place of eccentric 3 the relative needle bar crank 4 of phase place has lagged behind certain angle, so thread take-up tension lever mechanism 7 does not swing to minimum point in addition.Be rotated further main shaft 1, the direction of motion of eedle 9 changes, and begins to move up from minimum point, and thread take-up tension lever mechanism 7 is still to lower swing, thereby the distance between shank conducting mechanism 5 and the thread take-up tension lever mechanism 7 is increased, to the eedle alignment that makes on the shank 9, receive, wire loop is diminished.
Claims (3)
1. an industrial multineedle sewing machine is regulated the mechanism of wire loop size, and it comprises the drive motors that power is provided, and it is characterized in that: be in transmission connection by eccentric stiffener between driving main shaft and the needle bar crank mechanism; The below of eccentric stiffener is connected with thread take-up tension lever mechanism by spherojoint, and thread take-up tension lever mechanism level is also shown some through wires holes; Be arranged with the shank connecting rod in the needle bar crank mechanism, the shank connecting rod is connected with shank by the shank joint pin; The upper end of shank is provided with the shank conducting mechanism that has some through wires holes, and the lower end of shank is equipped with the pin folder that has some eedles; Suture passes the through wires hole on thread take-up tension lever, shank conducting mechanism, pin folder and the eedle successively.
