Automatic pattern sewing machine

Abstract

The invention particularly discloses an automatic pattern sewing machine which comprises a machine frame, a sewing mechanism extending to the outer side of the machine frame is arranged at one side of the top of the machine frame, a working panel corresponding to the sewing mechanism is arranged on the top of the machine frame, a needle plate mechanism is arranged on the working panel, a thread shaft fixing mechanism is arranged on the machine frame, a thread guide mechanism is arranged on the thread shaft fixing mechanism, The two sides of the top of the machine frame are each provided with a transmission mechanism, a first driving motor is arranged under the machine frame, the tops of the two transmission mechanisms are each provided with a first sliding frame which is arranged on the transmission mechanism in a sliding mode and axially connected with the transmission mechanism, the ends of the two first sliding frames are jointly fixedly provided with a second support, the second transmission mechanism is arranged in the second support, a cloth leather installing and fixing device is arranged on the second transmission mechanism, and a second driving motor is arranged in the side portion of the second support or the end portion of one of the first sliding frames. On the premise that the labor intensity of operators is reduced, it is ensured that stitches of patterns are stable, and the surface quality of the patterns is improved.

Description

technical field [0001] The invention relates to sewing equipment, in particular to an automatic pattern sewing machine. Background technique [0002] A traditional pattern sewing machine forms a stitch by forming a loop of the upper thread and inserting the lower thread through the loop of the upper thread to interweave the upper thread and the lower thread. The upper thread is passed through the needle from the bobbin, and the lower thread is accommodated in a shuttle having a tip while being wound around the bobbin. The loop is formed by raising the needle with the upper thread from the bottom dead center. The hook tip of the shuttle catches the loop, and the hook rotates while the loop is caught, and the bobbin passes the upper thread, whereby the upper thread and the lower thread intertwine. Here, as the preparatory stage of the sewing work, the operator sets the bobbin on the sewing machine, inserts the thread (needle thread) into the needle, and sets the thread (need...

AI Technical Summary

Problems solved by technology

Here, as the preparatory stage of the sewing work, the operator sets the bobbin on the sewing machine, inserts the thread (needle thread) into the needle, and sets the thread (needle thread) in the thread path. The traditional sewing machine has the following problems: one is that the labor intensity of the operator is relatively high, and the other is that the pattern needs to be manually moved to sew it out, which further increases the labor intensity of the operator.

[0003] For this reason, the current manufacturer has developed an automatic pattern sewing machine, which fixes the sewing mechanism and the needle plate mechanism of the pattern sewing machine together, and adds an X-axis moving mechanism, a Y-axis moving mechanism and a pattern sewing control device. Driving the sewing mechanism and the needle plate mechanism to move to complete the sewing of the pattern, although the labor intensity of the operator is reduced, but new technical problems arise: the poor stability of the sewing mechanism and the needle plate mechanism leads to unstable stitches of the pattern, and the pattern poor surface quality
