Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a lifting mechanism for front and rear casters of a machine head of an automatic warp drawing-in machine. Background Art

[0002] An automatic warp drawing-in machine consists of a machine head that performs the drawing-in process and a creel that secures the warp threads to form a curtain. Before operation, the yarns wound on the warp beam are secured side by side on a mechanism that tensions the warp threads, forming a curtain known as the creel. During operation, the machine head moves along the creel, threading the warp threads sequentially along the warp curtain arranged side by side. The machine head moves on the creel, specifically, the side-limiting guide wheels on the machine head move along the C-shaped steel channel of the creel. This requires raising the front and rear casters of the machine head so that the grooves of the side-limiting guide wheels accurately and smoothly fall onto the edges of the C-shaped steel channel of the creel, ensuring smooth and orderly drawing-in. However, a current problem is that when the front and rear casters of the machine head are in the non-raised position, the side-limiting guide wheels and the C-shaped steel channel of the creel are at a height difference, preventing them from contacting each other. If the side guide wheels cannot smoothly lower themselves, the machine head drawing-in mechanism and the creel curtain will deviate, preventing drawing-in. Utility Model Content
