Description

Technical Field

[0001] The utility model relates to the field of short fiber crimping machines, in particular to a short fiber crimping machine suitable for high glass transition temperature short fibers. Background Art

[0002] Staple fibers, also known as cut fibers, are widely used and can be woven into thin threads, thread ends, and hemp ropes. Usually, in the production process of staple fibers, a crimping machine is often required to wind them up. The crimping machine is used to wind the produced fibers onto a reel, which can realize automatic winding of the fibers.

[0003] After searching, a crimping machine for chemical fiber staple fibers with a publication number of CN202020326479.9 is disclosed, which specifically includes a base, a first support plate is fixedly connected to the right side of the top of the base, a second support plate is movably connected to the left side of the top of the base, and the tops of the first support plate and the second support plate on opposite sides are fixedly connected with connecting columns through bearings, and the two connecting columns are provided with prismatic holes on opposite sides, and a winding roller is arranged between the two prismatic holes. The utility model can quickly replace the winding roller after winding through the coordinated use of the base, the first support plate, the second support plate, the connecting column, the prismatic hole, the winding roller, the driving motor, the active belt pulley, the driven belt pulley, the hydraulic telescopic rod, the slide and the slider, and can clean the dust on the surface of the cloth during the process of winding the cloth through the coordinated use of the dust box, the dust collector, the isolation net, the sleeve, the spring, the movable rod, the dust cover and the hose, which brings great convenience to the winding work.

[0004] However, the above device still has certain defects. For example, after the above curling device has rolled up the fibers, the fibers wound into bundles on the curling roller need to be removed manually, and automatic rope removal cannot be achieved. The process is relatively time-consuming and labor-intensive.

[0005] Therefore, it is necessary to invent a short fiber crimping machine suitable for high glass transition temperature to solve the above problems. Utility Model Content

The first servo motor is fixed to the front side of the connecting member through the folding plate, and the first servo motor is used as a driving source to drive the second screw rod to rotate inside the folding plate.

[0011] Preferably, a rectangular groove is opened in the center of the inner cavity of the annular plate, and the bottom of the first screw rod is bolted with a first bevel gear through the rectangular groove, and the back side of the rectangular groove is rotatably connected to the second bevel gear through a bearing, and the surface of the second bevel gear is meshed with the surface of the first bevel gear.

[0014] Preferably, a feed roller is rotatably connected to the right side of the front side of the mounting plate via a bearing, and the short fiber line to be processed is transmitted to the curling roller through the opposite rotation of the feed rollers.
