Cloth pulling wheel device capable of being slightly adjusted for sewing machine

Abstract

The invention discloses a cloth pulling wheel device capable of being slightly adjusted for a sewing machine. The device comprises an installing bracket, a first motor, a slight adjustment connectingrod, a pulling wheel, a connecting mechanism and a belt transmission device, the installing bracket comprises an installing plate and a shell, and a notch is formed in the bottom of the shell; the slight adjustment connecting rod is inserted in the notch of the shell, the installing plate is connected with the slight adjustment connecting rod through a pivot, and the upper end of the slight adjustment connecting rod forms a bent tail portion; a screw capable of making contact with the shell is arranged on the tail portion, the pulling wheel is fixedly connected with the slight adjustment connecting rod, the first motor is connected with the pulling wheel through the belt transmission device, and a second motor is connected with the slight adjustment connecting rod through the connecting mechanism. According to the cloth pulling wheel device, the motors rotate to pull the pulling wheel upward, the operation that the pulling wheel is manually lifted and put down by hand is omitted, the work efficiency is improved, and accidental injuries are reduced; compared with an electromagnet and an air cylinder device which are used for lifting the cloth pulling wheel, the device is small in size, more portable, low in cost and capable of slightly adjusting the distance between the pulling wheel and a workbench according to different thicknesses of cloth.

Description

technical field [0001] The invention relates to a finely adjustable sewing machine mop wheel device, which belongs to the technical field of industrial sewing machines. Background technique [0002] During the sewing process of the sewing machine, due to the special reasons of the fabric and sewing thread and the special structure of the sewing machine, in order to ensure the flatness of the sewing material during the sewing process of the sewing machine, the market uses a device that can drag the fabric backward and drive the tug wheel upward. The moving rear dragging device ensures the flatness of sewing materials. [0003] However, most of the current market uses electromagnets and cylinder devices to lift the mop wheel. The electromagnet is bulky, generates heat, and is too large. The pneumatic device is troublesome to install in the factory, there are many pipelines, and the noise is loud during use. The pressure adjustment is inconvenient, and the mop wheel is pressed...

Problems solved by technology

[0003] However, most of the current market uses electromagnets and cylinder devices to lift the mop wheel. The electromagnet is bulky, generates heat, and is too large. The pneumatic device is troublesome to install in the factory, there are many pipelines, and the noise is loud during use. It is inconvenient to adjust the pressure, and the mop wheel is pressed below after shutdown, etc.

In addition, in the prior art, the distance between the tugboat and the workbench is fixed. Due to the different thickness of the fabric to be sewn, it is easy to cause the distance between the tugboat and the tabletop to not match the thickness of the fabric, affecting normal work.
