Electric dust suction device on sewing machine

Abstract

The invention belongs to the technical field of sewing machines, and particularly relates to an electric dust suction device on a sewing machine. The electric dust suction device comprises a waste collecting barrel, the upper end of the waste collecting barrel is provided with an air suction motor hood, the waste collecting barrel is communicated with an inner cavity of the air suction motor hood, an air suction motor is arranged in the air suction motor hood, an air suction opening is arranged in the waste collecting barrel, and an air suction tube is arranged on the air suction opening. Cost and complexity for mounting a large air pump are omitted to a great extent, an air suction and dust removal mechanism and mounting are simplified, and the mechanism is more convenient and practical and convenient to operate; as the handheld air suction tube is arranged, when the machine is unused, fabric clippings at a front door sheet and teeth are cleaned manually, and the handheld air suction tube can hung on a fixing hook under a bedplate when the machine is operated; by the principle, the problem that trimming influence is affected by accumulation of thread chains at an automatic thread trimmer of an overedger is solved more conveniently, the process of manually cleaning the fabric clippings is facilitated as well, and the electric dust suction device is simple to operate, attractive in complete-machine effect and practical.

Description

Technical field: [0001] The invention belongs to the technical field of sewing machines, in particular to an electric dust collector on a sewing machine. Background technique: [0002] During the sewing process of the sewing machine, dust is generated due to the friction between the suture and the fabric. The accumulation of dust will affect the normal operation of the sewing machine. At the same time, the floating dust in the workshop will affect the environment of the workshop and the health of the operators. The existing structure uses electromagnets in the process of thread trimming before and after, so the braids cannot be processed, and the braids are easily accumulated at the cutter, which affects the signal reception of the third sensor. Another situation is to use an air pump to suck air. By installing a large air pump in the factory building, each sewing machine is sucked through the pipeline to achieve dust suction. The amount of work in this way is large, and i...

Problems solved by technology

This method has a large amount of engineering and is not convenient for small garment factories.

Moreover, the installation is also very cumbersome and time-consuming, there are many suction ducts, the arrangement is messy, it is not beautiful, and the collection of waste is not convenient
