Description

Technical Field

[0001] The utility model belongs to the technical field of winding machines, and in particular relates to a winding mechanism for preventing a chemical fiber line bobbin from falling off. Background Art

[0002] Chemical fiber thread refers to yarn made from fibers processed by chemical or physical methods using natural or synthetic polymers as raw materials. The length, thickness, whiteness, gloss and other properties of these fibers can be adjusted during the production process to meet different needs. Chemical fiber thread has many advantages, such as light resistance, wear resistance, easy washing and drying, no mildew, no insect bites, etc. When winding the chemical fiber thread onto a bobbin, a winding machine is required to wind the bobbin, but the existing winding machine generally only clamps one end of the bobbin and simply limits the other end. When fixing a longer bobbin, the fixing stability is low and it is easy to fall off. It is also not well applicable to bobbins of different diameters and lengths. Utility Model Content

[0048] The working principle and use process of the utility model are as follows: when the device is used, one end of the bobbin is sleeved on the outside of one of the mechanical inner support fixing devices 16, and then the servo motor 7 at one end of the first adjustment track 2 is controlled to operate to drive the first bidirectional screw rod 4 to rotate, thereby driving the sliders on the inner side of the first adjustment track 2 to approach each other, and then driving the two sets of mechanical inner support fixing devices 16 to approach each other, until the spacing between the second connecting plates 19 in the two sets of mechanical inner support fixing devices 16 is the same as the length of the bobbin, at this time, the clamping adjustment motor 33 is controlled to operate to drive the second bidirectional screw rod 20 to rotate, thereby driving the threaded sleeve 21 to move towards each other, The support arm 23 is thereby driven to rotate, so that the inner support plate 25 is away from the protective cover 26, and the inner wall of the bobbin is stably supported.

At the same time, the device can adjust the height of the bobbin according to the thickness of the chemical fiber line wound on the outside of the bobbin. When adjusting, the electric cylinder 31 is controlled to push the upper support plate 9 to move upward, so that the height of the bobbin and the guide wheel mounting frame 27 can be adjusted synchronously. By setting the auxiliary support groove 29 and the auxiliary support slide 30, the support between the lower support plate 8 and the upper support plate 9 can be lifted. Stability. After the winding is completed, first control the clamping adjustment motor 33 in one group of mechanical inner support fixing devices 16 to run in reverse, driving the inner support plate 25 to release the support and fixation of the inner wall of the wire bobbin. At this time, the servo motor 7 on one side of the first adjustment track 2 can be controlled to drive the two groups of mechanical inner support fixing devices 16 to move away from each other, and then the other group of mechanical inner support fixing devices 16 can be controlled to release the fixation of the wire bobbin and remove the wire bobbin.
