Technical field
The utility model belongs to field of mechanical technique, relates to the down charging mechanism of a kind of two-needle sewing machine, particularly two-needle sewing machine.
Background technology
Two-needle sewing machine is widely used in the industrial sewing operation, and traditional two-needle sewing machine generally adopts pin feeding and following feeding feeding simultaneously.
The feeding simultaneously of traditional two-needle sewing machine suture needle and feeding tooth has good synchronism, for thicker cloth can be stable sew, and sewing quality is than higher.But when sewing, cause cloth wrinkling easily in the pin feeding process at relatively thinner cloth.Obviously, can influence after wrinkling sewing quality, but also stitching phenomenon not attractive in appearance appears appearing in one's mind etc. in feasible the sewing on cloth.
Existing other two-needle sewing machine also exists similar problem.Therefore, along with the segmentation in market and the intensive management of apparel industry, a Sewing machines is often only used in specific operation, makes specific lining.Special-purpose Sewing machines is in production efficiency, and aspects such as simplicity of operation all have advantage, and therefore, one is only descended the two-needle sewing machine of feeding necessary.
Summary of the invention
The purpose of this utility model is at existing in prior technology the problems referred to above, provides a kind of simple in structure, makes the down charging mechanism of the two-needle sewing machine that the two-needle sewing machine feeding stability is high.
The purpose of this utility model can realize by following technical proposal: a kind of down charging mechanism of two-needle sewing machine, be arranged at the power transmission shaft of two-needle sewing machine, between feed spool and the balance staff, power transmission shaft is connected with power section, be fixed with the feeding tooth on the feed spool, overlap after being fixed with balance staff on the balance staff, it is characterized in that, be fixed with cam on the described power transmission shaft, between power transmission shaft and feed spool, also be provided with connecting rod one and connecting rod two, one end of connecting rod one is socketed on the cam, the other end of connecting rod one is articulated on the connecting rod two, and the other end of connecting rod two is articulated in the feed spool sidepiece, and described balance staff is connected on the Sewing machines housing.
Power section is a motor, and in the driven by motor power transmission shaft rotation process, cam can be along with together rotating.Obviously, will drivening rod one in the cam rotation process around the swing by a small margin of one end, make by connecting rod two just can to drive the feed spool swing feeding tooth in the feed spool swing process and to move, thereby cloth to be carried by mobile feeding tooth.
Obviously, the balance staff that is connected on the housing can not move.It is the following feeding operation that said process has been finished two-needle sewing machine.
In the down charging mechanism of above-mentioned two-needle sewing machine, be provided with the needle gage seat mechanism that to regulate connecting rod one position between described connecting rod one and the Sewing machines housing.
Obviously, need control down during the feeding amount during feeding, can realize apart from seat mechanism by metering needle.
In the down charging mechanism of above-mentioned two-needle sewing machine, described needle gage seat mechanism comprises adjusting rod one and adjusting rod two, one end of adjusting rod one is articulated on the connecting rod one, and the other end of adjusting rod one is articulated in an end of adjusting rod two, and the other end of adjusting rod two is articulated on the Sewing machines housing.
Regulate the position of adjusting rod one and adjusting rod two, just can correspondingly make finally to make connecting rod one swing certain amplitude to that is to say the amplitude of fluctuation that changes feed spool to have changed the distance that move back and forth of feeding tooth on needle plate.
In the down charging mechanism of above-mentioned two-needle sewing machine, described needle gage seat mechanism also comprises a fixed axis, and the other end of above-mentioned adjusting rod two is socketed on the fixed axis.
As can be seen, mobile fixed axis just can change the position of adjusting rod one and adjusting rod two, thereby can adjust the amplitude of fluctuation of feed spool easily.
In the down charging mechanism of above-mentioned two-needle sewing machine, be with a sleeve on the described feed spool, the other end of above-mentioned connecting rod two is articulated in the sleeve sidepiece.Sleeve is connected mutually with feed spool, drives sleeve during connecting rod two swings and together swings, and correspondingly also just makes the feed spool swing.
In the down charging mechanism of above-mentioned two-needle sewing machine, overlap after being provided with balance staff between described balance staff and the Sewing machines housing, cover is connected on the Sewing machines casing behind the balance staff, and balance staff puts after being connected in balance staff by screw.Balance staff can be connected on the housing of Sewing machines firmly by such structure.
Compared with prior art, the down charging mechanism of this two-needle sewing machine only by connecting rod one, connecting rod is second-class forms, therefore, it relatively simple for structure, cost is lower, has advantages of high practicability.Simultaneously, power transmission shaft rotates in the feeding process, can make the feeding tooth carry out feeding by connecting rod smoothly once, connecting rod two, and its stability in use is also than higher.
Description of drawings
Accompanying drawing is the perspective view of this two-needle sewing machine down charging mechanism.
Among the figure, 1, power transmission shaft; 2, feed spool; 3, feeding tooth; 4, needle plate; 5, cam; 6, connecting rod one; 7, connecting rod two; 8, sleeve; 9, adjusting rod one; 10, adjusting rod two; 11, fixed axis; 12, screw; 13, overlap behind the balance staff; 14, balance staff.
The specific embodiment
As shown in the figure, two-needle sewing machine comprises a power transmission shaft that is connected with motor 1, the balance staff 14 that is connected with suture needle and a feed spool 2 that is connected with feeding tooth 3, and feeding tooth 3 is positioned at needle plate 4 places.
The down charging mechanism of this two-needle sewing machine is arranged between power transmission shaft 1, feed spool 2 and the balance staff 14.Be fixed with a cam 5 on the power transmission shaft 1, between power transmission shaft 1 and feed spool 2, also be provided with connecting rod 1 and connecting rod 27, one end of connecting rod 1 is socketed on the cam 5, and the other end of connecting rod 1 and connecting rod 27 are hinged, and the other end of connecting rod 27 is articulated in feed spool 2 sidepieces.
