Machine needle driving mechanism for spatial four-rod embroidery machine

Abstract

The invention discloses a machine needle driving mechanism for a spatial four-rod embroidery machine. The mechanism mainly comprises a power input part, a box body, a driving mechanism and a power output part, wherein the power input part mainly comprises a main shaft and a pair of bevel gears mounted on the main shaft and a driving rod; the driving mechanism comprises a spatial four-rod part and a planar four-rod part which are connected through a swinging shaft. According to the machine needle driving mechanism for the spatial four-rod embroidery machine, power is input by the main shaft, transmission is carried out through the bevel gears, swinging of the swinging shaft is realized through the spatial four-rod mechanism, the power is output through the planar four-rod mechanism, and a machine needle driving block can slide up and down. The stroke and movement speed of a needle rod can be regulated by regulating the planar four-rod part according to actual situations.

Description

technical field [0001] The invention relates to the needle drive field of embroidery machines, in particular to a space four-bar embroidery machine needle drive mechanism. Background technique [0002] The needle driving mechanism is one of the core components of the embroidery machine, which has high requirements on the motion characteristics. At present, the needle driving mechanism of the existing embroidery machine mainly adopts the horizontal arrangement of the power shaft. When the distance is small, the power shaft is difficult to install. The cam transmission mechanism widely used in the market, due to the compact structure, the impact of power input is relatively large, the cam is seriously worn, it is difficult to replace and the design of the cam is difficult. In the cam needle drive mechanism, a single cam is directly connected to the needle drive slider. The movement speed and stroke of the slider cannot be adjusted, and the scope of use is strictly limited. C...
