Technical Field:
[0001] The utility model relates to the technical field of yarn processing equipment, and more specifically, to a yarn conveying structure of a gill box. Background Art:
[0002] The existing gill box is a machine that relies on a pin row roller drafting mechanism to draft, card, and combine fiber strips, making the fibers straight and parallel and then forming fiber strips of a certain thickness;
[0003] In the conveying frame of the existing gill box, it is necessary to convey the fiber strips (composed of multiple yarns) in multiple cylinders. In order to prevent the fiber strips coming out of the cylinders from winding during the conveying process, it is necessary to separate the two. A plurality of guide rods are installed on the conveying frame, and a guide through groove is formed between two adjacent guide rods, so that the fiber strips are conveyed along the guide through groove to separate adjacent fiber strips and prevent entanglement. However, during the conveying process, the conveying of the fiber strips will shift to one side, and it may be pressed against one of the guide rods for conveying, which will cause one of the guide rods to be severely worn due to excessive pressure, thus affecting its service life and requiring frequent replacement, resulting in high replacement costs. Summary of the Utility Model:
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a yarn conveying structure of a gill box, which can finely adjust the corresponding left adjusting plate and middle adjusting plate back and forth. When the fiber strips conveyed in the conveying channel or the second conveying channel are pressed against one of the guide rods, the corresponding left adjusting plate or middle adjusting plate is finely adjusted and moved towards the guide rod on this side to reduce the pressure, thereby reducing the wear of the guide rod and ensuring its normal conveying and guiding use.
