Description
Technical Field
The utility model relates to a looper swing control device of a sewing machine, which has the advantages of simple structure, low cost, light weight and convenient installation.
Background
A sewing machine, also known as a sewing machine or a sewing machine, is a machine used for textile, and can sew textile or other articles with threads. A sewing machine is a machine that interweaves or stitches one or more layers of material through one or more sewing threads to form one or more stitches in the material. The sewing machine can sew fabrics such as cotton, hemp, silk, wool, rayon, etc. The sewed stitch is neat, beautiful, flat and firm, the sewing speed is high, and the use is simple and convenient. With the development of sewing machine technology, the types of sewing machines are very many, including domestic sewing machines, industrial sewing machines and computer sewing machines. The sewing machine greatly improves the production efficiency of the textile and clothing industry, and is one of indispensable production devices in the textile industry. When a curved needle crank on the existing sewing machine swings left and right, the swing amplitude of the curved needle driving the sewing machine cannot be changed, so that the use of a user is influenced, and the defects of troublesome operation and high cost are brought.
Disclosure of Invention
The utility model aims at providing a sewing machine looper amplitude of oscillation controlling means that simple structure, with low costs, light in weight, simple to operate.
The purpose of the utility model is realized by the following technical scheme.
The utility model provides a sewing machine looper amplitude of oscillation controlling means which characterized in that: the looper swing control device of the sewing machine comprises a connecting crank, and the connecting crank is connected with a looper crank of the sewing machine; one connecting rod on the connecting crank is hinged with the curved needle connecting rod, and the other connecting rod on the connecting crank is connected with a pull rod on the sewing machine.
The connecting rod on the connecting crank is connected with the curved needle connecting rod through a ball connecting head hinge.
The connecting crank is connected with a curved needle crank of the sewing machine through a connecting pin.
The other connecting rod on the connecting crank is positioned in a hole of the pull rod of the sewing machine.
Compared with the prior art, the utility model has the following advantages.
The utility model has the advantages of simple structure, low cost, light weight and convenient installation.
Drawings
FIG. 1 is a schematic view of an assembly structure of the looper swing control device of the sewing machine of the present invention;
fig. 2 is a schematic view of the exploded structure of the components of the looper swing control device of the sewing machine of the present invention.
Detailed Description
The looper swing control device of the sewing machine of the present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the looper swing control device of the present invention comprises a connecting crank 1, the connecting crank is connected to a looper crank 2 of the sewing machine, a connecting rod on the connecting crank is hinged to a looper connecting rod 3, and another connecting rod on the connecting crank is connected to a pull rod 4 on the sewing machine. The connecting rod on the connecting crank is hinged with the curved needle connecting rod through a ball connector 5. The connecting crank is connected with a connecting pin 6, the connecting crank is sleeved on the connecting pin and fixed through a screw 7, and the connecting crank can rotate left and right. The upper and lower positions of the ball connector are changed by pulling the pull rod left and right, so that the linear distance between the connecting crank and the ball connector is changed, the purpose of changing the swing amplitude of the looper is achieved, and the sewing stitch is changed.
The utility model has the advantages of simple structure, low cost, light weight and convenient installation.
