Intelligent full-synchronized pattern sewing machine

Abstract

The invention discloses an intelligent full-synchronized pattern sewing machine. The sewing machine comprises an upper casing, a needle bar synchronous rotary mechanism and a shuttle race synchronous rotary mechanism. The needle bar synchronous rotary mechanism is arranged at one end of the upper casing, and the shuttle race synchronous rotary mechanism is mounted below the needle bar synchronous rotary mechanism and rotates synchronously with the needle bar synchronous rotary mechanism. When the intelligent full-synchronized pattern sewing machine performs sewing, the needle bar synchronous rotary mechanism and the shuttle race synchronous rotary mechanism can drive a needle bar and a shuttle race to rotate synchronously according to a line moving direction to enable the sewing direction of a sewing needle to be consistent with a set sewing line track, so that high-quality and perfect sewing is achieved, and the sewn line track has the advantages of being compact, orderly and uniform and identical with the set sewing line track; and the practicality is high, and wide industrial utilization values are provided.

Description

technical field [0001] The present invention relates to the technical field of sewing machines, and more specifically relates to an intelligent fully synchronous pattern that can realize the synchronous rotation of the shuttle bed and the needle bar, so that the sewing direction of the sewing needle is always consistent with the stitches to be sewn. sewing machine. Background technique [0002] The traditional sewing mechanism generally includes an upper casing and a lower casing, an upper shaft motor and a needle bar mechanism installed on the upper casing, and an upper shaft motor and a needle bar mechanism that are respectively connected to the upper shaft motor and the needle bar mechanism in the upper casing. Shaft, as well as the lower shaft motor and the shuttle bed mechanism installed on the lower casing, are formed by the lower shaft which is installed in the lower casing and is respectively connected with the lower shaft motor and the shuttle bed transmission.

[0002] The traditional sewing mechanism generally includes an upper casing and a lower casing, an upper shaft motor and a needle bar mechanism installed on the upper casing, and an upper shaft motor and a needle bar mechanism that are respectively connected to the upper shaft motor and the needle bar mechanism in the upper casing. Shaft, as well as the lower shaft motor and the shuttle bed mechanism installed on the lower casing, are formed by the lower shaft which is installed in the lower casing and is respectively connected with the lower shaft motor and the shuttle bed transmission. The upper shaft is driven by the upper shaft motor to rotate, and the upper shaft The shaft drives the needle bar mechanism to move up and down to realize the up and down sewing action of the sewing needle. The lower shaft motor drives the lower shaft to rotate, and the lower shaft drives the shuttle bed mechanism to move to cooperate with the sewing needle for sewing operations. When the needle bar and the shuttle bed cannot realize the corresponding rotation according to the sewing line at the same time

[0003] When the sewing machine is sewing, because the feeding mechanism will generate a certain thrust on the material to be sewn during the feeding process, and the thrust will also act on the bottom thread and the upper thread, causing the bottom thread and the upper thread to be twisted, and because The needle bar and shuttle bed of the existing sewing mechanism cannot be rotated, so affected by the push and pull of the feeding mechanism when feeding, the force on the bottom thread and the upper thread is unbalanced when sewing at the thread hook position, and the sewing direction of the sewing needle cannot meet the set requirements. The sewing stitches are consistent, which eventually leads to loose, uneven, uneven stitches and other defects

Especially when sewing irregular stitches, it is difficult for the stitching direction of the sewing needle to be consistent with the stitches set to be sewn, resulting in very loose, uneven, and uneven stitches that cannot be matched with Setting the stitches to be sewed to be completely consistent will seriously affect the appearance of the product and the sewing quality, and affect the overall quality of the product, resulting in a low pass rate of the product

[0004] Along with the raising of people's quality of life, people also more and more higher to the quality requirement of sewing, so above-mentioned existing sewing machine obviously does not meet the needs of today's society, urgently needs to be further improved
