Description

Balance structure
Technical Field
The utility model relates to the technical field of sewing machines, in particular to a balance structure.
Background
A sewing machine (Sewingmachine) is a machine that uses one or more sewing threads to form one or more stitches on a material to interweave or stitch one or more layers of material.
The sewing machine can sew cotton, hemp, silk, wool, artificial fiber and other fabrics, leather, plastic, paper and other products, and the sewn stitch is neat, beautiful, flat, firm, fast in sewing speed and simple and convenient to use. And the artistic forms of hand-push embroidery, computerized embroidery and the like are derived from the hand-push embroidery.
When the traditional sewing machine works, an upper thread must pass through the needle bar, a balance and a thread clamp of the traditional sewing machine are partially arranged at the traditional position of the machine shell, the lowest point of the balance is lower than the upper plane of the needle bar, the problem of large thread passing pressure exists, the tension of an upper thread bottom thread is difficult to adjust, and a series of problems of throwing the upper thread bottom thread, rotting the thread, non-straight line and the like are easily caused.
Disclosure of Invention
The utility model aims to solve the problems in the prior art, and provides a balance structure which can adjust the tension of an upper thread bottom line, reduce the thread passing pressure, enable the thread passing to be smoother, improve the thread passing precision and improve the working efficiency of a sewing machine.
The utility model solves the technical problems by adopting the technical scheme that: the balance structure comprises a take-up crank, an inner hole is formed in the take-up crank, a take-up lever is arranged above the inner hole and connected to the take-up crank, one end of the take-up lever is connected with the take-up crank, the other end of the take-up lever is connected with the take-up lever crank, a take-up connecting rod is arranged above the take-up lever crank, one end of the take-up connecting rod is connected with the take-up lever, and the other end of the take-up connecting rod is connected with a take-up lever pin.
And a first clamping spring is arranged between the thread take-up lever pin and the thread take-up connecting rod, and is arranged on the thread take-up lever pin and positioned on the outer surface of the thread take-up connecting rod.
And a second clamping spring is arranged between the thread take-up lever and the thread take-up connecting rod, and the second clamping spring is arranged on the thread take-up lever and positioned on the outer surface of the thread take-up connecting rod.
The beneficial effects of the utility model are as follows: the balance disclosed by the utility model has a reasonable structure, and through the structure of the thread taking-up crank, the needle bar and the balance can be ensured to synchronously act, so that the thread passing pressure is reduced, the tension of the bottom thread of an upper thread can be regulated, the thread passing pressure is reduced, the thread passing is smoother, the thread passing precision is improved, and the working efficiency of a sewing machine is improved.

Reference numerals illustrate: the device comprises a thread take-up crank 1, an inner hole 2, a thread take-up lever 3, a thread take-up lever crank 4, a thread take-up connecting rod 5, a thread take-up lever pin 6, a first clamping spring 7 and a second clamping spring 8.
Detailed Description
The utility model is further described below with reference to the accompanying drawings:
referring to the drawings: the balance structure in the embodiment comprises a take-up crank 1, an inner hole 2 is formed in the take-up crank 1, a take-up lever 3 is arranged above the inner hole 2, the take-up lever 3 is connected to the take-up crank 1, one end of the take-up lever 3 is connected with the take-up crank 1, the other end of the take-up lever 3 is connected with a take-up lever crank 4, a take-up connecting rod 5 is arranged above the take-up lever crank 4, one end of the take-up connecting rod 5 is connected with the take-up lever 3, and the other end of the take-up connecting rod 5 is connected with a take-up lever pin 6.
A first clamping spring 7 is arranged between the thread take-up lever pin 6 and the thread take-up connecting rod 5, and the first clamping spring 7 is arranged on the thread take-up lever pin 6 and positioned on the outer surface of the thread take-up connecting rod 5.
And a second clamping spring 8 is arranged between the thread take-up lever 3 and the thread take-up connecting rod 5, and the second clamping spring 8 is arranged on the thread take-up lever 3 and positioned on the outer surface of the thread take-up connecting rod 5.
During operation, the take-up lever pin 6 is fixed on the sewing machine, the take-up crank 1 rotates around the inner hole 2 and sequentially drives the take-up lever crank 4, the take-up lever 3 and the take-up connecting rod 5 to act for taking-up, the upper thread directly passes through the take-up connecting rod 5 during taking-up action through the structure of the take-up lever crank 4, the take-up lever 3 and the take-up connecting rod 5, the upper thread and the needle bar synchronously work through the action of the crank connecting rod, the thread passing pressure is reduced, the thread passing is smoother, the thread passing is more stable, the thread passing precision is improved, and the working efficiency of the sewing machine is improved.
