Abstract

The invention relates to an oil return device of a middle needle rod of an electrical pattern-sewing machine, comprising: a shell head (1), a first oil pipe (20), an oil box (30), an upper shaft (4), and a suit (5) of the upper shaft and a middle shaft, and a plunger (54), wherein, one end of the first oil pipe (20) is connected with the shell head (1), the suit (5) of the upper shaft and the middle shaft is sleeved on the upper shaft (4) and eccentrically connected with the upper shaft at the contacting point of the upper shaft (4); the suit (5) of the upper shaft and the middle shaft comprises a first oil pipe joint (51) connected with the other end of the first oil pipe (20), a second oil pipe joint (52) connected with the oil box (30) through a second oil pipe (53); the other end of the plunger (54) is provided with a plunger spring (55); and a fixing screw (56) is positioned on the plunger spring (55). Since a plunger is adopted to suck oil, the oil seeping at the pin rod part is decreased and clothes can be prevented from being stained by oil.

Description

technical field [0001] The invention relates to an electronic pattern machine, in particular to an oil return device at the needle bar of the electronic pattern machine. 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 Figure 1 that in the electronic pattern machine in the prior art, the lubrication technology adopts oil line lubrication, and the oil line adopts the principle of siphon phenomenon for oil supply and oil return, that is, the casing head 1 is connected to the oil box 3 through the oil pipe 2 Together; take this method, easy to store oil in the ...
