Description

Technical Field

[0001] The utility model relates to a reel installation mechanism, in particular to a reel installation mechanism of a wire dividing machine, which is mainly used in the wire dividing machine and belongs to one of the components of the wire dividing machine. Background Art

[0002] In the process of chemical fiber production, the first thing to do is to separate the strands into single filaments, and then wind the separated single filaments on the reel. Therefore, the reel installation mechanism is one of the important components of the wire splitting machine, located at the rear of the wire splitting machine, for placing the reel.

[0003] The general reel installation mechanism is driven to rotate by a motor installed inside the wire dividing machine. When in use, the reel is sleeved on the reel installation mechanism and the motor drives the unwinding operation. However, the reel installation mechanism in the prior art has the following technical defects:

[0004] 1. The existing reel installation mechanism has a fixed outer diameter and is generally only suitable for fixing a reel of a specific size, and its versatility is poor. The utility model patent with patent number CN212741655U proposes a reel installation mechanism that can fix reels of various inner diameter specifications, but the base of the reel installation mechanism is a fixed cone, and the outer diameter of the supporting frame is much larger than the outer diameter of the fixed cone. When in use, the reel has no reliable limiting mechanism to limit its position, and it is very easy to leave the reel installation mechanism, resulting in unstable installation of the reel.

[0005] 2. In the prior art, the connecting piece on the adjusting hand wheel is provided with an internal thread, which is directly meshed and sleeved with the external thread of the rotating shaft. Although this structure seems to reduce some parts and make the structure more streamlined, when in use, the adjusting hand wheel is very heavy and cannot be tightened with the supporting frame on the rotating shaft by manpower. In addition, the outer wall of the connecting piece is smooth and round, and tools such as wrenches cannot be used, which makes the adjusting hand wheel easy to loosen on the rotating shaft, resulting in unstable installation of the reel.

[0006] 3. In the prior art, the support frame is a plurality of sheet-shaped slot structures, and the movable support plate is inserted into the slot structure when in use. Although the movable support plate is installed firmly in this structure, the overall weight of the support frame is heavy, making the entire reel installation mechanism very bulky and not conducive to the rotation of the shaft.

[0007] Based on this, the present invention is proposed to solve the above problems. Utility Model Content

[0008] In view of the above-mentioned technical problems of the prior art, the purpose of the utility model is to provide a reel mounting mechanism for a wire dividing machine, which has a base installed at the tail end, which is not only suitable for reels of various inner diameters, but also realizes the limitation of the reel, making the reel installation more stable; and improves the structure of the adjusting handwheel assembly so that it can be stably installed at the end of the rotating shaft; simplifies the structure of the supporting frame, reduces the overall weight, and is more conducive to the rotation of the rotating shaft.
