A feeding device for an industrial sewing machine

Abstract

The invention discloses a feeding device for an industrial sewing machine, which comprises an equipment platform, a cloth roller mechanism is arranged on one side of the equipment platform, a first belt slot is arranged on the equipment platform, an equipment bracket is arranged at the lower end of the equipment platform, and an equipment bracket is arranged at the lower end of the equipment bracket. There are self-locking rollers distributed in an array, and there are also tensioning roller frames that are mirror images of each other on the equipment platform. Tensioning wheels are installed on the inside of the tensioning roller frames, and bearing frames that are mirror images of each other are installed on the side of the equipment platform. A first rolling rod is arranged between the bearing frames, a first detection mechanism is arranged under the equipment platform, a leveling mechanism is arranged on the equipment platform, and a second detection mechanism is also arranged on the equipment platform. The invention has a large amount of cloth feeding, can carry out double cloth transportation at one time, greatly improves the transportation efficiency of the cloth, and is convenient for detecting and processing the cloth at the same time, with high detection accuracy, which is beneficial to improving the sewing quality of the cloth, and further avoids the Damaged sewing machine needles caused by fabric problems.

Description

technical field [0001] The invention relates to a production field, in particular to a feeding device for an industrial sewing machine. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing materials. During the use of the sewing machine, in the sewing machine, sewing Cloth needs a cloth conveying mechanism. Chinese patent 201320878828.8 provides an upper feeding amount adjustment mechanism of an overlock sewing machine. The adjusting rod is outside the sewing machine frame, while the fork rod, the front and rear feed shafts, etc. are inside the sewing machine frame, and a bifurcated branch is formed at one end of the fork rod, and a fork is slidably inserted into the branch.

[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing materials. During the use of the sewing machine, in the sewing machine, sewing Cloth needs a cloth conveying mechanism. Chinese patent 201320878828.8 provides an upper feeding amount adjustment mechanism of an overlock sewing machine. The adjusting rod is outside the sewing machine frame, while the fork rod, the front and rear feed shafts, etc. are inside the sewing machine frame, and a bifurcated branch is formed at one end of the fork rod, and a fork is slidably inserted into the branch. The small slider is connected with the large slider and the connecting rod through a pin. When the front and rear adjustment lever is operated to make it rotate in the front and rear direction along the front and rear adjustment scale plate, the front and rear feed shafts rotate around the axis. Rotate, and change the position of the large slider in the adjustment groove of the adjustment crank through the fork rod, small slider and pin, so as to change the distance between the swing axis and the large slider, thereby changing the distance through the connecting rod The amount of swing of the crank connected to the large slider, this way of feeding the cloth is likely to cause unevenness of the cloth and affect the sewing quality. Generally, the amount of cloth for industrial sewing is relatively large. In view of this situation, a feeding device for industrial sewing machines is now proposed
