Description

Technical Field

[0001] This utility model belongs to the field of drawing frames, and in particular relates to an integral drafting seat structure for a drawing frame. Background Technology

[0002] The function of a drawing frame is to improve the internal structure of the sliver, thereby increasing the uniformity of its long segments, reducing weight unevenness, straightening and paralleling the fibers in the sliver, reducing hooks, ensuring the fineness meets specifications, and uniformly mixing different types or qualities of raw materials to achieve the specified blending ratio. The drafting frame structure is an important component of the drawing frame.

[0003] Comparing with Chinese Patent CN220887823U, an integral drafting seat structure for a drawing frame is disclosed, including a base; a rear pressure roller assembly rotatably mounted on the base, comprising a rear pressure roller shaft and a rear pressure roller body, one end of which passes through one side of the base from the outside to the inside and is rotatably connected to the base, with the length direction of the rear pressure roller shaft flush with the bottom surface of the base and perpendicular to the corresponding side of the base; one end of the rear pressure roller shaft located inside the base is fitted with the rear pressure roller body, and the other end is fitted with a rear pressure pulley; a roller assembly mounted on the upper end of the base and parallel to the rear pressure roller shaft; and a rear transmission shaft assembly mounted on the base. This structure is simple, highly precise, and achieves five-axis common reference for the rear pressure roller shaft, three roller shafts, and the rear transmission shaft, unifying the machining and assembly references, effectively ensuring parallelism and perpendicularity, making it suitable for widespread application.

[0004] However, after the aforementioned patented sliding adjustment is fixed by bolts, it is prone to loosening under stress during operation, resulting in poor stability. Therefore, a new device needs to be designed. Utility Model Content
