ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an improved knitting machine, particularly a multi-function machine which is adapted to producing several types of fabrics including single knit, plain terry, double knit, single jacquard, double jacquard.
2. Description of the Prior Art
A conventional knitting machine can only knit using one method and thus produces a single type of fabric such as single knit, double knit, or jacquard. Although the configuration and structure of these machines vary only slightly, they often cannot be arranged to knit using different methods. Thus, a knitting factory needs to purchase different machines having different functions in order to meet the needs of producing different kinds of fabrics so as to meet different demands of clients and seasonal change. Due to changing fashions and seasons, the amount and type of the fabrics also change over time. Thus, different types and amounts of fabric are needed at different times, therefore leaving some machines inoperable at any given moment. Furthermore, knitting machines are expensive and occupy a significant amount of space on the factory floor.
SUMMARY OF THE INVENTION
Therefore, it is the primary object of the present invention to provide an improved knitting machine having interchangeable components such as upper and lower cylinder mechanisms, a dust cleaning system, and rings for fixing thread. By the design of the present invention, the components can be converted and replaced simply and conveniently in order to achieve the shift in functions and avoid the waste of cost of machines.
According to the above object, the main components of the present invention include mechanical main body, cylinder mechanism, yarn feeders, and fabric winding system. The cylinders are mounted on the top of the base of the main body. The upper and lower cylinder mechanisms are driven by synchronous shafts. The yarn is transmitted from yarn feeders to cylinders and then knitted to clothes and wound by the fabric winding system. The apparatus is characterized in that upper and lower cylinder mechanisms are all interchangeable so that the upper cylinder can be replaced with radial dust cleaning system. In addition, an upper support rack and a set of rings for feeding thread can be mounted on the base. Therefore, the present invention has multi-functions, wherein the upper and lower cylinders can be adjusted or replaced, or added with optional elements such as an upper support rack, rings for feeding thread and radial dust cleaning system in order to convert the model of producing fabric from one to another.
The foregoing object and advantages of the present invention will be more apparent from the following detailed description, as taken in conjunction with the accompanying drawings wherein;
