Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a knotting string guide device for a tying machine, and is used to prevent bundling errors.

Conventional technology A needle is operated from the binding passage side where grain culms are tied to the knot side of a string holder, knot building, etc., and a string guide groove is provided for inserting and guiding the end of the binding cord through the binding passage side of the platform. A string tensioning spring is provided with an appropriate free movement distance between the platform and the platform, and the free end of the string tensioning spring crosses the string guide groove to elastically tension the string end. There is a technique in which a tying string is held by this string tension spring, and the tying string is gripped and knotted by the operation of a knotting bill.

Problems to be Solved by the Invention However, when the grain culms that are sequentially fed into the tying passage are concentrated and compressed into the tying section by the packer, the string tension springs may be pushed by the grain culms, or the culms may be pressed during the tying process. Due to the tension of the binding string, the binding string held under tension by the string tensioning spring may come off from the string tensioning spring, and the knot bill grabs this detached binding string, resulting in a tying error.

Therefore, this invention prevents the grain culms that are focused and compressed into the binding part by the packer from coming into contact with the string tension spring.

Furthermore, the tension of the tying string is not directly applied during the tying process to prevent tying errors due to the tying string coming off the string tension spring.
