Problems solved by technology

[0002] There is a cloth guide wheel structure inside the automatic sewing machine. The cloth guide wheel can provide tension to the fabric and transport the fabric. However, the cloth guide wheel can only provide the tension of the fabric but cannot adjust the position and direction of the fabric. The sewing machine will be set to sense whether the fabric deviates The sensor of the normal route, the sensor senses the edge of the fabric. If the fabric cannot be sensed, it means that the fabric has deviated from the normal route. At this time, manual deviation correction is required, which is time-consuming and laborious, and the deviation correction effect is not good

Abstract

The invention discloses a deviation correcting device of automatic circular lower hem sewing machine. The deviation correcting device comprises a support and a transmission mechanism, wherein the transmission mechanism comprises a transmission shaft, a first guide mechanism is connected with the rear end of a rotating frame, the first guide mechanism comprises a row of first guide wheels which are distributed left and right and can rotate along with rotation of the rotating frame, an upper fixing plate and a lower fixing plate are fixed to the top and the bottom of the support correspondingly, a second guide mechanism and a third guide mechanism are arranged on the upper fixing plate and the lower fixing plate correspondingly, the second guide mechanism and the third guide mechanism are symmetrically arranged, the second guide mechanism comprises a row of second guide wheels distributed left and right and a second guide assembly used for driving the second guide wheels and the first guide wheels to rotate synchronously, a third guide wheel mechanism comprises a row of third guide wheels distributed left and right, and the second guide assembly is connected with the rotating frame through a connecting assembly. The first guide wheels, the second guide wheels and the third guide wheels can rotate to adjust cloth to be conveyed according to a normal route, and thus the purpose of adjusting the position of the cloth is achieved.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to an automatic deviation correcting device for round hem sewing machines. Background technique [0002] There is a cloth guide wheel structure inside the automatic sewing machine. The cloth guide wheel can provide tension to the fabric and transport the fabric. However, the cloth guide wheel can only provide the tension of the fabric but cannot adjust the position and direction of the fabric. The sewing machine will be set to sense whether the fabric deviates The sensor of the normal route senses the edge of the fabric. If the fabric cannot be sensed, it means that the fabric has deviated from the normal route. At this time, manual deviation correction is required, which is time-consuming and laborious, and the deviation correction effect is not good. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the object of the present inve...
