Description

Technical Field

[0001] This utility model relates to a wear-resistant false twister, belonging to the technical field of loom accessories. Background Technology

[0002] Water jet looms are shuttleless looms that use jet water to guide the weft yarn through the shed. Water jet weft insertion provides greater frictional traction on the weft yarn than air jet weft insertion, with less diffusion, making it suitable for inserting weft into smooth-surfaced synthetic fibers, glass fibers, and other long filaments. During the weaving process on a water jet loom, the waste selvage is located on the outside of the reed width. A certain amount of waste selvage interweaves with the weft yarn, thus holding the weft yarn end, achieving tension to prevent weft shrinkage and ensuring a neat and smooth selvage. During production, the weft yarn held by the waste selvage needs to be cut, and a false twister is used to false twist the waste selvage, holding the cut weft yarn flat to prevent the cut weft yarn fragments from scattering. However, in existing water jet looms, due to the humid environment, the false twister used to collect the waste selvage has a short service life, requiring replacement approximately every six months. Damaged components are usually the bearings used for rotation. Therefore, developing a wear-resistant false twister is a problem that needs to be solved. Utility Model Content

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Combination Figures 1 to 7 This utility model provides a detailed description of the present invention. The wear-resistant false twister of the present invention includes a false twister bushing 1, a pulley 2, a hollow rod 3, and a pulley 4.

[0024] The pulley 4 is located near the end of the hollow rod 3 and is fixedly connected to the false twister bushing 1, so that the pulley 4 does not rotate; the hollow rod 3 is fixed to the pulley 2, and the hollow rod 3 is driven to rotate by the pulley 2.

[0025] The hollow rod 2 is connected to the false twister bushing 1 via a bearing 12, and a wear-resistant ceramic bushing 13 is provided between the bearing 12 and the false twister bushing 1; one end of the wear-resistant ceramic bushing 13 extends to one-third to two-thirds of the pulley 2. In this embodiment, the wear-resistant ceramic bushing 13 extends to half of the pulley 2. The wear-resistant ceramic bushing 13 has good wear resistance, which can significantly improve the service life of the bearing. Furthermore, the wear-resistant ceramic bushing 13 extends into the pulley 2, which can prevent humid air from entering the bearing position at this location, further reducing corrosion of the bearing and internal metal, and also extending its service life.

[0026] Furthermore, the pulley 2 has a pulley recess 21 on its surface near the false twister bushing 1. The depth of the pulley recess 21 is one-third to two-thirds of the thickness of the pulley 2; in this embodiment, it is chosen to be one-half. The wear-resistant ceramic bushing 13 includes a first wear-resistant ceramic bushing and a second wear-resistant ceramic bushing made of wear-resistant ceramic. The first wear-resistant ceramic bushing includes a first ceramic bushing body 131, one end of which is provided with an annular protrusion 132. The second wear-resistant ceramic bushing includes a second ceramic bushing body 133, one end of which is provided with a coaxial protrusion 134. During assembly, a ceramic bushing body 131 is fitted onto the outside of the hollow rod 3, and the end with the protrusion 132 is fixed to the bottom of the pulley recess 21, specifically by adhesive bonding. The outer surface of the second wear-resistant ceramic bushing body 133 is fixed to the inner surface of the false twister bushing 1, specifically by adhesive bonding. Furthermore, the second wear-resistant ceramic bushing body 133 is fitted outside the first ceramic bushing body 131, with one end of the protruding post 134 facing the side of the protrusion 132. That is, the first wear-resistant ceramic bushing is bonded and fixed to the pulley 2, and the second wear-resistant ceramic bushing is bonded and fixed to the false twister bushing 1. The friction between wear-resistant ceramics replaces the friction between metals in the prior art, thus improving service life. Further, a hole 135 is provided on the side wall of the second ceramic bushing body 133.

[0027] Furthermore, a fixed bushing 14 is fixedly provided at the end of the hollow rod 3; the end of the hollow rod 3 protrudes from the fixed bushing 14. The pulley 4 includes two cam portions 42 and a connecting portion 43 connecting the two cam portions 42; one of the cam portions 42 contacts the end of the hollow rod 3, and the pulley 4 can slide along the end of the hollow rod 3 during use, forming a notch due to wear. A groove 44 is provided on the surface of the connecting portion 43.

[0028] Furthermore, a first connecting rod 8 and a second connecting rod 9 are fixedly provided on the false twister bushing 1; the end of the second connecting rod 9 is fixed to the pulley; the first connecting rod 8 is L-shaped and has a fixing hole 10, at which the false twister can be fixedly connected to the frame of the water jet loom by bolts.

[0029] Furthermore, the hollow rod 3 includes a cylindrical hollow section 31, a transition section 32, and a flat section 33; the transition section 32 is provided with a first through hole 5, and the flat section 33 is provided with a second through hole 6 and a third through hole 7. In use, the yarn passes through the third through hole 7 and the second through hole 6 in sequence, passes through the transition section 32 and the cylindrical hollow section 31 from the position of the first through hole 5, and then passes around the pulley 4. The pulley 2 is connected to a power source via a belt, and the power source drives the pulley 2 to rotate, thereby driving the hollow rod 3 to rotate, so that the yarn passing through the flat section 31 achieves a false twist effect.

It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort.
