Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of spindles, and particularly relates to a novel fine yarn spindle spindle. BACKGROUND

[0002] Fine yarn is the main and key process of spinning in cotton spinning engineering, and the fine yarn process is the last process related to yarn quality, with the continuous updating and development of the fine yarn machine, especially the application of automatic doffing fine yarn machine, the doffing efficiency is greatly improved, and labor intensity and production cost are reduced. The spindle is one of the main components of twisting and winding on the fine yarn machine, the spindle is composed of a spindle rod, a spindle, a spindle core, a spindle foot and a spindle hook, the spindle is tightly sleeved on the middle part of the spindle rod, is drum-shaped and is made of cast iron, and is a transmission part of the spindle.

[0003] A fine yarn spindle spindle is disclosed in Chinese Utility Model Patent No. 202321713135.3, which is composed of a spindle rod and a spindle. The spindle rod is fixedly connected with an assembly block outside the spindle rod, the assembly block is a cuboid, and the spindle is located outside the assembly block. The guide blocks on both sides of the inner wall of the spindle are slidably connected with the guide grooves on both sides of the outer wall of the assembly block, so that the two form an integral whole for transmitting torque. A locking cap is rotatably connected above the spindle, and the locking cap is threadedly connected with the spindle rod to limit and install the spindle. In addition, clamping holes are formed on both sides of the outer wall of the spindle, and wear-resistant sheets are attached to the outer wall of the spindle. The wear-resistant sheets are semicircular and have clamping columns fixedly connected with the inner surfaces thereof. The clamping columns are clamped with the clamping holes to firmly clamp the wear-resistant sheets, so that the damaged wear-resistant sheets can be replaced. Anti-slip patterns are arranged on the outer surfaces of the wear-resistant sheets to increase the friction between the wear-resistant sheets and the spindle.

[0004] In the above technical solution, the wear-resistant sheets are fixed to the outer wall of the spindle by clamping, so the fixation is not stable. Since the spindle is a transmission part of the spindle, it needs to rotate, and it is easy to fall off under the action of centrifugal force. In addition, the wear-resistant sheets cannot be tightly attached to the spindle by clamping, so the wear-resistant sheets will collide with the spindle during use, causing vibration and affecting the stability of the spindle and the quality of the yarn.

[0005] Therefore, a novel fine yarn spindle spindle is provided. UTILITY MODEL CONTENTS
