Mechanism heat-dissipating device of sewing machine adopting direct drive motor

Abstract

The invention discloses a mechanism heat-dissipating device of a sewing machine adopting a direct drive motor. The mechanism heat-dissipating device is mainly characterized in that: a heat-dissipating groove is arranged at a position, corresponding to a main shaft, on a sewing machine body; a corresponding clapboard is fixed on the heat-dissipating groove and is provided with a through hole; an adaptor is fixed on the outer side of the clapboard and is provided with a through groove; the main shaft passes through the through hole of the clapboard and the through groove of the adaptor and is positioned in the center of the adaptor, which ensures the convenient arrangement of the rotor of the direct drive motor on the main shaft without deviation; moreover, a fan blade is arranged in the through hole; the fan blade is fixed on the main shaft and rotates synchronously with the main shaft to make use of heat generated during the operation of an outside air-cooling rotor and the main shaft; and air is introduced into an internal member of the sewing machine through the heat-dissipating groove, so heat dissipation is realized.

Description

technical field [0001] The invention relates to a heat dissipation device for a sewing machine mechanism of a direct drive motor. Background technique [0002] The sewing machine is an indispensable tool for sewing garments. In recent years, in order to adapt to the diversification of the performance of clothing fabrics, especially the emergence of functional fabrics, the garment industry has carried out many transformations on the sewing machine. The current high-speed sewing machine can even reach 100% per minute. The speed of tens of thousands of revolutions, in addition, some industry players are focusing on the adoption of lubrication systems, the application of direct-drive motors, the application of program-controlled methods, the design of personalized shapes, etc., all of which push the development of sewing machines to a peak. [0003] The above-mentioned sewing machine can be fixedly connected with a direct-drive motor on the main shaft installed on the main body,...

AI Technical Summary

Problems solved by technology

[0005] 1. When the above-mentioned sewing machine fixes the direct-drive motor on the main shaft, due to the lack of alignment structure, the direct-drive motor often cannot exactly correspond to the main shaft and there is a deviation

[0006] 2. The above-mentioned sewing machine lacks a heat dissipation structure for the internal components between the direct drive motor and the main shaft, and the heat generated by the direct drive motor and the internal components of the sewing machine at high speed will not be dissipated smoothly
