The present invention relates to a fiber blowing and heat dissipation system, and more particularly, to a fiber blowing and heat dissipation system applicable to a circular knitting machine for weaving a single-sided knit fabric.

In order to make the knitting operation more smooth during the knitting process of the circular knitting machine, a cotton yarn must be pulled tightly, which usually generates cotton fibers during its feeding, guiding and feeding process. If these cotton fibers are not removed, the cotton fibers are likely to stick to the respective parts of the circular knitting machine, which may cause problems in the smooth knitting operation and shorten the life of the circular knitting machine. Moreover, such cotton fibers are knitted together with the cotton yarn. If cloth is produced, product defects and quality deterioration of the cloth are caused.

In view of the above disadvantages, for example, Taiwan Patent Publication No. 286689 entitled "Dust disposal device of circular knitting machine" and "Fiber blowing device of circular knitting machine" machine, as described in Taiwan Patent Publication No. 267459 entitled "machine" and Taiwan Patent Publication No. 429974 entitled "Improved fiber blowing device of circular knitting machine". Many devices for removal have been proposed in the prior art. Here, the dust removal device disclosed in the publication related to the "dust removal device of a circular knitting machine" is configured to be driven by a crank rod mechanism to move the fiber blowing fan up and down, The disclosed apparatus consists of a rotating nozzle having a plurality of nozzles capable of releasing air in different tangential directions. In the case of this fiber blowing device, the nozzle is automatically rotated when air is released to generate concentrated airflow on the vertical lead surface of the circular knitting machine. Also, in the publication entitled "Improved thread end removing vibratory pipe of knitting machine", the pressurized air is ductile in order to guide the air accurately to the target area. Disclosed is a method for allowing the passage of a soft flexible tube while adjusting the wall thickness of the flexible tube.

It should be noted that most fiber blowers for circular knitting machines are configured to blow fibers at the thread feed position. However, it has been found by the inventors of the present invention that cotton fibers are likely to occur at the position of the thread passing plate, thread feed nozzle, and knitting needle of the circular knitting machine, where the thread pass plate and thread feed nozzle pass through the cotton yarn during the knitting process. It is because it is provided with the hole and opening for making it. Cotton yarns continuously rub with the holes and openings of the thread passing plate and the thread feed nozzles to produce cotton fibers, and the knitting needles easily produce cotton fibers during the process of spinning or hooking the yarns. Due to the high speed rotation over a long time, the knitting needles are generally at a high temperature. In the case of existing conventional fiber blowers, any means that can be used for circular knitting machines, which can blow the fibers at a position where cotton fibers are likely to generate while concentrating airflow at those positions to lower the temperature of the heat generating position. Is not considered. Therefore, there is a need for an immediate interest and a feasible solution to find a method that can be used in existing circular knitting machine applications while effectively blowing cotton fibers while lowering the temperature.

The main object of the present invention is a friction between a rotating needle cylinder and a knitting needle while blowing cotton fibers from the thread passing eyelet of the thread passing plate of the circular knitting machine, the thread feeding hole of the thread feeding nozzle, and the knitting needle. To provide a fiber blowing and heat dissipation system of a single-sided circular knitting machine, which is configured to concentrate the air flow to lower the temperature of the heat generated by, according to the present invention, the knitting operation can be made more stably and smoothly, the life of the circular knitting machine It can maintain and guarantee the quality of knitted products.
