Sewing machine with dust collection device

Abstract

The invention relates to a sewing machine, in particular to a sewing machine with a dust collection device. The sewing machine comprises a fan, an air suction pipeline and a dust collecting bag. A suction opening of the air suction pipeline is formed below a needle plate, the other end of the air suction pipeline is connected with the fan, and an air outlet of the fan is connected with the dust collecting bag. Due to the fact that the air suction pipeline is arranged below a bottom plate of the sewing machine, dust generated in the sewing process can be effectively removed and prevented from accumulating on various movable parts, and the probability that the sewing machine breaks down is reduced. A dust blowing mode is changed into a dust suction mode, so that pollution caused by the dust to workshop environment is reduced, and air quality in a workshop is guaranteed.

Description

technical field [0001] The invention relates to a sewing machine, in particular to a sewing machine with a dust suction device. Background technique [0002] During the working process of the sewing machine, the friction between the needle, the thread and the fabric will generate a lot of dust such as cuttings and thread scraps on the end of the cloth, and a large amount of dust will accumulate on the peripheral part of the needle plate of the machine head, and the generated dust will pass through the needle drop hole of the needle plate When the dust enters the sewing machine base at the lower part of the needle plate, and gradually adheres to the fixed parts such as the feed dog drive mechanism, the rotary hook and other movable parts or bearing parts inside the sewing machine base, when the accumulation of dust reaches a certain amount, It will cause poor rotation of movable parts such as feed dogs and hooks. Since there are many parts around the needle plate and the sp...

Problems solved by technology

[0002] During the working process of the sewing machine, the friction between the needle, the thread and the weaving fabric will produce a lot of dust such as cuttings and thread scraps on the end of the fabric, and a large amount of dust will accumulate on the needle head of the machine head. At the periphery of the needle plate, the generated dust enters the sewing machine base at the lower part of the needle plate through the needle drop hole of the needle plate, and gradually adheres to various movable parts or bearings such as the feed dog drive mechanism and the rotary hook inside the sewing machine base. When the accumulation of dust reaches a certain amount, it will cause poor rotation of movable parts such as feed teeth and hooks.

Since there are many parts around the needle plate and the space is small, it is impossible to clean it with a rag. Every time you clean it, you can only open the cover plate and use compressed air to blow off the fiber debris accumulated inside. The result of this is a lot of fine dust Diffuse into the air, destroying the cleanliness of the air, causing harm to the hygiene and health of sewing operators, and resulting in deterioration of the working environment
