Abstract
The utility model relates to a high-speed sewing machine which belongs to the field of knitting equipment modification. The high-speed sewing machine comprises a machine head; a tension mechanism and a curved thread-pressing needle are arranged on the machine head; the tension mechanism comprises a first tensioner and a second tensioner; a spring take-up is arranged on one side of the second tensioner; and a first tensioner is arranged above the spring take-up. In the utility model, a stitching thread tension mechanism is newly designed, the curved thread-pressing needle is modified, and the phenomena of thread breakage, insufficient stretching of threads, irregularity of threads, needle fault of stitching threads and the like caused by the fact that cashmere yarns are used in the high-speed sewing machine as the stitching threads, so that machine can satisfies the stitching requirement of wool products completely, and the production efficiency of the linking procedure can be improved.
Description
Technical field
The utility model relates to a kind of extra-rapid stitching machine, belongs to knitting equipment and transforms the field.
Background technology
At present, domestic cashmere textile enterprise in process of production, the running-on operation is all used and is just being overlapped sewing machine, this stitching speed of just overlapping sewing machine is slower, must dispose enough just overlap sewing machine and supporting employee for guaranteeing manufacturing schedule.The production time of delivery of cashmere industry is more concentrated, and very strong seasonality is arranged, and current running-on technical staff is in short supply, often incurs loss through delay the friendship phase because of running-on operation manufacturing schedule, and the running-on operation becomes the bottleneck that company produces.The stitching speed of extra-rapid stitching machine is common 5-10 times of just overlapping sewing machine, a horizontal line of the head of this sewing machine is provided with two tensioners, this structure makes thread tension excessive, can not use powerful low suture to sew up, and can not be used for the stitching of high-grade cashmere product.
Summary of the invention
The purpose of this utility model is to provide a kind of extra-rapid stitching machine that the cashmere suture is sewed up cashmere product that can be used for.
Technical solution: the utility model comprises: head, head is provided with tension mechanism, line ball looper, described tension mechanism comprises first tensioner, second tensioner, and a side of second tensioner is provided with the spring Pick Wire, and spring Pick Wire top is provided with first tensioner.
First tensioner comprises central shaft, and central shaft is provided with thread tension disc, spring, and thread tension disc, spring are fixed by nut.
The side needle tray degree of depth of line ball looper is 1-2.5mm.
The second tensioner center and spring Pick Wire center are on same horizontal line.
The utility model has designed new suture tension mechanism, has transformed the line ball looper, phenomenons such as broken string, drawing lines stretching deficiency, the drawing lines of extra-rapid stitching machine when making suture with cashmere yarn is irregular, suture run-bake-needle fault have been solved, make this machine can satisfy the stitching requirement of cashmere product fully, improve the production efficiency of running-on operation.

The specific embodiment
The utility model is the oblique upper that is positioned at spring Pick Wire 2 tops, second tensioner 1 at original position mounting spring Pick Wire 2, the first tensioners 3 that first tensioner 3 is installed of extra-rapid stitching machine head.The air line distance of first tensioner 3 and second tensioner 1: 100-130mm, first tensioner 3 becomes place, 20-35 degree angle with the horizontal center line of second tensioner 1, the center of the center of second tensioner 1 and spring Pick Wire 2 is on same horizontal line, and the spring on second tensioner 1 is that coefficient of elasticity is 0.13-0.15N/mm.First tensioner 3 comprises central shaft 5, and thread tension disc 6, spring 7 are installed on the central shaft 5, and thread tension disc 6, spring 7 are fixed by nut 9 by pad 8.
The side needle tray degree of depth of the utility model line ball looper 4 is 1-2.5mm.
The method of wearing of the utility model extra-rapid stitching machine suture: as shown in Figure 2, suture 11 is introduced from first tensioner, 3 oblique uppers, passes the thread tension disc 6 of first tensioner 3, walk around spring Pick Wire 2, pass second tensioner 1 again, penetrate suture needle, can sew up through one group of twizzle.
The main mechanical action of extra-rapid stitching machine is: during machine run, to treat the stitchbonded fabric feeding by a pair of feeding-wheel, simultaneously also drive the suture needle of horizontal direction, the take-up looper of horizontal direction and the line ball looper 4 of vertical direction, finish chain sewing in the porch of feeding-wheel.This can reach 4000S.P.M to the stitching speed of this machine.
Improved tension mechanism thread tension when sewing up is soft and flexible, and simultaneously, we increase 1.5mm to the line ball looper side point of vertical direction, makes when sewing up not run-bake-needle fault of suture.Transform by these, solved broken string, the drawing lines of extra-rapid stitching machine when making suture not enough, the problems such as drawing lines is irregular, suture run-bake-needle fault that stretch, make this machine can satisfy the stitching requirement of cashmere product fully, improve the production efficiency of running-on operation with cashmere yarn.
