Mechanism for regulating drive at X-direction and inter space of driven gear in electro-pattern-sewing machine

Abstract

The invention relates to a mechanism to regulate an X direction drive and a driven gear gap of an electrical pattern machine, comprising a shell (1), an X direction step motor (10), a shaft (101) of the X direction motor (10), an X direction drive gear (20), a first hole (30), a second hole (50), an installation shaft (501) of a driven gear, an X direction driven gear (40), and also an eccentric regulation board (60). The eccentric regulation board (60) is positioned on the shaft (101) of the X direction step motor (10) and between the X direction drive gear (20) and the X direction step motor (10); one side of the eccentric regulation board (60) is fixed with the X direction step motor (10), the other side is fixed with a board provided with the first hole (30). The invention has the advantages that: by adding an eccentric regulation board, the service life of the gear is prolonged as well as the processing precision of the shell is reduced and the cost is decreased.

Description

technical field [0001] The invention relates to an electronic pattern machine, in particular to a gap adjustment mechanism between the X-direction driving gear and the X-direction driven gear. Background technique [0002] Electronic pattern machine (SGY2-1306H) is a special equipment for bags, leather, labels and other garments, mainly used for their decorative sewing. [0003] The machine uses a direct-drive servo motor to drive the upper shaft, and the X-axis and Y-axis are both driven by stepping motors. It is programmed through pattern-making software and computer-controlled to complete various patterns of sewing equipment. [0004] It can be seen from Fig. 1 that in the electronic pattern machine in the prior art, the X-direction stepping motor 10 is installed in the casing 1, and the X-direction driving gear 20 is fastened on the shaft 101 of the X-direction stepping motor 10 and placed on the first On the hole 30, the X-direction driven gear 40 is fastened on the in...

Problems solved by technology

[0004] It can be seen from Fig. 1 that in the electronic pattern machine in the prior art, the X-direction stepping motor 10 is installed in the casing 1, and the X-direction driving gear 20 is fastened on the shaft 101 of the X-direction stepping motor 10 and placed on the first On the hole 30, the X-direction driven gear 40 is fastened on the installation shaft 501 of the second hole 50. This structure makes the meshing gap between the driving and driven gears determined by the center distance between the first hole 30 and the second hole 50. To ensure that if the machining accuracy of the casing is not good, the center distance is too large or too small, it will affect the meshing clearance of the gears and affect the performance of the machine
