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 sleeve of the rotary hook 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 rotary hook and the needle plate, because the oil in the oil groove flows to the lubricating parts through multiple channels. The oil hole and the oil seepage hole are small and easy to be blocked by dust, and it is difficult to achieve a good lubrication 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 , causing oil stains on the embroidery, making the quality of the embroidery unqualified. Therefore, in actual use, there is little or no oil on the hook, which makes the hook and the shaft easy to wear
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 "200820062328.6" 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.

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0022] Such as figure 1 As shown, the lubrication system for the rotary hook assembly of the embroidery machine of the present invention is applicable to both single-head embroidery machines and multi-head embroidery machines. The main pipe 2 is connected to multiple branch pipes 8, and each branch pipe 8 is connected to a set of rotary hook components. , So as to realize the lubrication of multiple sets of rotary hook components. The lubricating system of the rotary hook component of the embroidery machine of the present invention includes a rotary hook component oil supply device and a rotary hook component. The rotary hook assembly includes a rotary hook 16, a rotary hook shaft 13, and a rotary hook sleeve 18. One end of the rotary hook shaft 13 is fixedly connected with the rotary hook 16, and the other end is connected with the main drive shaft 12 thr...

Abstract

The invention relates to a lubrication system for rotating shuttle components of embroidery machines, in particular to a rotating-shuttle-component lubrication system consisting of a rotating shuttle, a rotating-shuttle shaft and a rotating-shuttle shaft sleeve, wherein the inside of the rotating-shuttle shaft is provided with a through hole coaxial with the rotating-shuttle shaft; one end of the through hole is a lubricating oil inlet communicated with a rotating-shuttle oil supply device through a duct, and the other end of the through hole is a lubricating oil outlet communicated with an inner cavity of the rotating shuttle; and the surface of the rotating-shuttle shaft is provided with an oil spray hole communicated with the through hole. The lubrication system not only can continue oiling the rotating shuttle, the rotating-shuttle shaft and the rotating-shuttle shaft sleeve, but also can cool and clean the components.

Description

Technical field [0001] The invention relates to a lubricating system for a rotary hook component of an embroidery machine, in particular to a lubricating system for a rotary hook component of an embroidery machine composed of a rotary hook, a rotary hook shaft, and a rotary hook shaft sleeve. Background technique [0002] The rotary hook components of the existing embroidery machine include the rotary hook, the rotary hook sleeve, and the rotary hook shaft. When the main drive shaft of the embroidery machine rotates one circle, the rotary hook shaft needs to rotate two times. The shaft sleeve of the rotary hook is easy to wear and needs frequent lubrication. The commonly used lubrication method is to manually or automatically drip the lubricating oil into the oil groove set on the rotary hook and the needle plate, because the oil in the oil groove flows to the lubricating parts through multiple seepages. The oil holes and oil seepage holes are small and easy to be blocked by dust...
