Automatic lubrication system of rotating shuttle assembly of embroidery machine

Abstract

The invention relates to an automatic lubrication system of a rotating shuttle assembly of an embroidery machine, in particular to a lubrication system of a rotating shuttle assembly, which comprises a rotating shuttle, a rotating shuttle shaft and a rotating shuttle shaft sleeve, wherein a blind hole which is coaxial to the rotating shuttle shaft is arranged in the rotating shuttle shaft, the end of a through hole of the blind hole is communicated with an inner cavity of the rotating shuttle, and an oil through hole which is communicated with the blind hole is arranged on the surface of the rotating shuttle shaft. The invention can not only continuously charge oil into the rotating shuttle, the rotating shuttle shaft and the shaft sleeve thereof, but also can cool and clean the components.

Description

technical field [0001] The invention relates to an automatic lubricating system for an embroidery machine rotary hook assembly, in particular to an automatic lubrication system for an embroidery machine rotary hook assembly composed of a rotary hook, a rotary hook shaft and a rotary hook shaft sleeve. Background technique [0002] The rotary hook assembly of the existing embroidery machine includes a rotary hook, a rotary hook shaft sleeve, and a rotary hook shaft. The shuttle shaft sleeve is easy to wear and needs to be lubricated frequently, and the commonly used lubrication method is to manually or automatically drop the lubricating oil into the oil groove set on the hook and the needle plate, because the oil in the oil groove flows to the lubricating parts through multiple oil seepages. The oil seepage hole is small and easy to be blocked by dust, so it is difficult to achieve a good lubricating effect; in addition, because the oil is directly added to the rotary hook, t...

Problems solved by technology

[0002] The rotary hook assembly of the existing embroidery machine includes a rotary hook, a rotary hook shaft sleeve, and a rotary hook shaft. The shuttle shaft sleeve is easy to wear and needs to be lubricated frequently, and the commonly used lubrication method is to manually or automatically drop the lubricating oil into the oil groove set on the hook and the needle plate, because the oil in the oil groove flows to the lubricating parts through multiple oil seepages. The oil seepage hole is small and easy to be blocked by dust, so it is difficult to achieve a good lubricating effect; in addition, because the oil is directly added to the rotary hook, the amount of oil injected cannot be controlled, and the oil in the rotary hook is often thrown onto the embroidery. Oil stains will be produced on the embroidery, and the quality of the embroidery will be unqualified. Therefore, in actual use, there is little or no oil on the rotary hook, resulting in easy wear and tear on the rotary hook and the rotary hook shaft

In order to reduce the wear of the rotary hook and the rotary hook shaft, improve the lubricating effect, and prevent the lubricating oil from being thrown onto the embroidery, a Chinese utility model patent with the patent number "200820062628.6" and the name "automatic refueling mechanism for the rotary hook of an embroidery machine" has disclosed a An automatic refueling mechanism for a rotary hook, which is provided with a shaft center through hole on the axis of the rotary hook shaft, one end communicates with the oil control mechanism, and the other end communicates with the rotary hook. The automatic refueling mechanism for the rotary hook with this structure can only Refueling of the rotary hook, neither the rotary hook shaft and the rotary hook sleeve, nor the scissors and other parts around the rotary hook that need to be lubricated.
