Abstract
The invention discloses a thread pulling device for a quilt sewing machine. The thread pulling device comprises a first connecting plate and a second connecting plate which are connected through a connecting block, a first gear is connected to the first connecting plate, a second gear matched with the first gear is connected to the second connecting plate, a crank is connected to the second gear, the middle of the crank is connected with one end of the connecting rod, the other end of the connecting rod is connected to the connecting block through a bolt, and a through hole is formed in the first connecting block and is located below the first gear. The thread pulling device is simple in structure and convenient to manufacture, and the crank is driven by a transmission crank to achieve the thread pulling motion; as the motion amplitude of the crank is changed along with changes of the length of a thread pulled in the thread pulling motion, too tight thread pulling or too loose thread pulling occurring in the working process of the quilt sewing machine is effectively avoided, thread breakage is reduced, and the working efficiency of the quilt sewing machine is improved.
Description
Technical field
The present invention relates to sewing quilt machine equipment technical field, be specifically related to a kind of wire picking device for sewing quilt machine.
Background technology
Sewing quilt machine is a kind of textile machine for making the upper linear pattern such as mattress, bedcover and cotton-wadded quilt, and wire picking device is the important component part of sewing quilt machine, it is mainly used to the bracing wire action realizing sewing quilt machine, sewing quilt machine in the course of the work, utilize wire picking device by the line pull-out on sewing quilt machine line cylinder, then realize making by eedle action.
Wire picking device on existing sewing quilt machine is when realizing bracing wire action, cannot according to from line cylinder pull out line length adjust the movement range of bracing wire, thus cause wire picking device to occur the short-term phenomenon that bracing wire tension produces in the course of the work, and bracing wire relaxes and will affect the operating efficiency of sewing quilt machine.
Summary of the invention
For the problems referred to above, the invention provides a kind of wire picking device for sewing quilt machine, its can according to from the line cylinder of sewing quilt machine pull out line length adjust the movement range of bracing wire, effectively prevent broken string phenomenon, also improve the operating efficiency of sewing quilt machine simultaneously.
In order to solve the problem, technical scheme provided by the invention is:
A kind of wire picking device for sewing quilt machine, comprise the first connecting plate and the second connecting plate, described first connecting plate is connected by contiguous block with the second connecting plate, described first connecting plate is connected with the first gear, described second connecting plate is connected with the second gear matched with the first gear, described second gear is connected with crank, be connected with one end of connecting rod in the middle part of described crank, the described connecting rod other end is bolted on contiguous block, described first connecting plate is provided with through hole, and described through hole is positioned at below the first gear.
Preferably for a wire picking device for sewing quilt machine, described first gear has been bolted the second crank, has been connected in the middle part of described second crank with one end of second connecting rod, the described second connecting rod other end is bolted on the second contiguous block.
Preferably for a wire picking device for sewing quilt machine, described second crank end is provided with the second connecting hole.
Preferably for a wire picking device for sewing quilt machine, described crank end is provided with connecting hole.
Preferably for a wire picking device for sewing quilt machine, described first connecting plate is connected with the first gear by bolt.
Preferably for a wire picking device for sewing quilt machine, described second gear is connected with crank by bolt.
Beneficial effect of the present invention is:
The present invention drives crank-motion by transmission device, bracing wire action is realized again by crank, due to crank movement range along with on the line cylinder of sewing quilt machine pull out the length of line and change, effectively avoid the too tight or too loose situation of bracing wire that sewing quilt machine occurs in the course of the work, both reduce broken string phenomenon, also improve the operating efficiency of sewing quilt machine.
