Embodiment Construction

[0032] The present invention will be further described below with specific embodiment, see figure 1 -7:

[0033] A kind of direct-drive roller cart, comprising a main shaft mechanism, a needle bar swing mechanism 1, an upper feeding mechanism 2 and a lower feeding mechanism, the main shaft mechanism is driven by a main shaft motor 3, the needle bar swing mechanism 1 is driven by a needle bar swing motor 4, The upper feeding mechanism 2 is driven by the upper feeding motor 5, and the lower feeding mechanism is driven by the lower feeding motor 6. The main shaft motor 3, the needle bar swing motor 4, the upper feeding motor 5 and the lower feeding motor 6 are controlled by the controller to move independently or interact with each other. Cooperate with exercise.

[0034] Specifically, the main shaft mechanism includes a main shaft 7, the main shaft 7 is connected with the main shaft motor 3, the main shaft 7 is connected with the lower shaft 8 through a transmission mechanism, ...

Abstract

The invention belongs to the technical field of sewing machines and particularly relates to a direct-drive roller sewing machine. The direct-drive roller sewing machine comprises a spindle mechanism, a needle rod swing mechanism, an upper feeding mechanism and a lower feeding mechanism, wherein the spindle mechanism is driven by a spindle motor, the needle rod swing mechanism is driven by a needle rod swing motor, the upper feeding mechanism is driven by an upper feeding motor, the lower feeding mechanism is driven by a lower feeding motor, and the spindle motor, the needle rod swing motor, the upper feeding motor and the lower feeding motor are controlled by a controlled to move or are mutually coordinated to move. The direct-drive roller sewing machine has the advantages that the needle swing mechanism, the upper feeding mechanism and the lower feeding mechanism changes an original pure mechanical transmission mechanism into a motor direct-drive mechanism, the defect that the pure mechanical transmission mechanism is complex ins structure, many in parts, complex in assembling and high in fault rate is overcome, the direct-drive roller sewing machine is compact in structure, assembling work efficiency is increased, and machine work efficiency is increased.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of sewing machines, in particular to a direct-drive roller car. [0003] Background technique: [0004] The roller car adopts roller and needle feeding synchronous feeding, with strong climbing ability and extremely stable needle pitch. Sewing leather, canvas, plastic and other fabrics, smooth and even, no wrinkle, no deformation. Ball and needle bearings are adopted, with good lubricating performance, low friction, low noise and durability. It is suitable for sewing riding boots, men's boots, women's boots, sports shoes, casual shoes, labor insurance shoes, high-grade leather shoes, bags, sofas, etc. The needle bar oscillating mechanism, the upper feeding mechanism and the lower feeding mechanism of the existing roller car are driven by a purely mechanical mechanism, which has the defects of many parts, complicated assembly, and high failure rate. [0005] Invention content: [0006] The object o...
