Problems solved by technology

However, when sewing curved stitches on the fabric, especially on computer-controlled sewing machines, the fabric is moved non-directionally, that is, in addition to forward feeding, there are also feeding methods such as oblique feeding, horizontal feeding, and reverse feeding. ;Under different feeding methods, since the moving direction of the cloth is not always parallel to the rotati

Abstract

The invention belongs to the technical field of machinery and discloses an industrial sewing machine. A needle holder is driven to do vertical reciprocation by a swing rod and is driven to rotate around the needle holder axis by a needle holder rotation motor. A rotary hook and a hook carrier are mounted on a hook carrier assembly which comprises a shell, a rotary disc, a circular rotary seat, a belt pulley ring, a rotary hook motor, an assembly bearing and a slip ring. The rotary hook assembly is driven to do horizontal rotation by a rotary hook motor. Cloth to be sewn is clamped by a cloth feeding mechanism to do plane moving between the needle holder and the rotary hook. The needle holder rotation motor, the rotary hook carrier motor and the rotary hook motor are connected to a programmable logic controller on a table through the slip ring. The programmable logic controller drives the needle holder and the rotary hook carrier assembly to do rotation with same phase and same angular velocity. Products sewn by the industrial sewing machine have stable and firm stitches, and the industrial sewing machine is particularly suitable for sewing leather/cloth products in variable curved shapes.

Description

technical field [0001] The invention belongs to the field of machinery, in particular to a sewing machine. Background technique [0002] Sewing machine is mainly made up of needle bar, machine needle and rotary hook. In previous sewing machines, the needle bar drives the needle to reciprocate vertically, and the rotary shuttle swings back and forth under the needle. The coordinated action of the two makes the upper and lower stitches form chain stitches on the fabric to sew multiple layers of fabric. This monotonous movement of the needle bar and the rotary hook has a good sewing effect when the material is fed in the forward direction (the cloth leaves the operator in a straight line), and the straight stitches are neat and firm. However, when sewing curved stitches on the fabric, especially on computer-controlled sewing machines, the fabric is moved non-directionally, that is, in addition to forward feeding, there are also feeding methods such as oblique feeding, horizont...
