Description

Technical Field

[0001] The utility model relates to the field of textile equipment, in particular to a godet roller of a texturing machine. Background Art

[0002] A texturing machine is a kind of textile machinery that can twist and deform untwisted filaments such as polyester and polypropylene into elastic filaments with medium and low elastic properties; for the utility model patent with the application number: CN202222068273.2, it clamps the rotating rod through the axial pressure of the extrusion spring, installs the rotating rod in the godet roller for winding the yarn. After the rotating rod is installed, due to the elasticity of the extrusion spring, the rotating rod has a margin of axial movement and is prone to axial movement during the winding process. Moreover, the rotating rod lacks circumferential limitation and is prone to self-rotation, thus affecting the winding quality of the yarn; in addition, this patent axially limits the extrusion spring through two sets of abutting rods and annular grooves. During installation, it is necessary to align the abutting rod with the transverse groove and push it inward to the position of the annular groove, and then rotate the abutting rod to be misaligned with the transverse groove to achieve axial limitation. When removing the rotating rod, it is necessary to rotate the abutting rod to the position aligned with the transverse groove, and then withdraw it from the transverse groove. The axial pressure of the extrusion spring on the rotating rod disappears after it returns to its original length, and then the rotating rod can be removed. The installation and removal process of the rotating rod is troublesome and inefficient. Summary of the Invention

[0016] Combined with the drawings, the utility model includes a grooved drum body 1, an axial notch 2 is opened on the grooved drum body 1, a turntable 3 coaxial with the grooved drum is provided at each end of the notch 2, a rotating shaft 4 is fixed on the outside of the turntable 3, the rotating shaft 4 is installed on the grooved drum through a bearing 5, one of the rotating shafts 4 extends out of the grooved drum and is connected with a driving motor, two eccentric rollers 6 are installed on the inner side of each turntable 3, the axes of the two eccentric rollers 6 are vertically arranged and symmetrically installed front and back, each eccentric roller 6 is connected with a driving motor, when the two eccentric rollers 6 rotate, the distance between the two eccentric rollers 6 will change; it also includes a winding shaft 7, two arc-shaped grooves 8 are opened on the outer wall of each end of the winding shaft 7, the two arc-shaped grooves 8 are symmetrically arranged front and back, when the distance between the two eccentric rollers 6 is large, the end of the winding shaft 7 is placed between the two eccentric rollers 6, as the two eccentric rollers 6 rotate, the distance between the two eccentric rollers 6 decreases, and the two eccentric rollers 6 will clamp the winding shaft 7, the rotation of the rotating shaft 4 will drive the turntable 3 and the winding shaft 7 to rotate synchronously, and the outer wall of the eccentric roller 6 fits with the arc-shaped groove 8 on the same side, which can axially position and circumferentially position the winding shaft 7, so that the winding shaft 7 cannot rotate relative to the rotating shaft 4 and cannot move axially.

[0017] The eccentric roller 6 is in a waist-shaped cylindrical form with larger diameters at both ends and a smaller diameter in the middle. During the process of the two eccentric rollers 6 clamping the winding shaft 7, the winding shaft 7 will ultimately be pushed to the position with the smallest diameter of the two eccentric rollers 6, thereby positioning the height of the winding shaft 7.

[0018] A bearing cavity 9 is provided at the end of the bobbin body 1. The bearing 5 is installed in the bearing cavity 9. The outer end of the bearing cavity 9 is sealed by an end cap 10. The rotating shaft 4 at the driving end penetrates through the bearing cavity 9 and the end cap 10 and extends out of the bobbin.

[0019] An oil injection hole 11 is opened on the bobbin. The oil injection hole 11 communicates with the bearing cavity 9. Lubricating oil can be injected into the bearing cavity 9 through the oil injection hole 11.

[0020] Sealing rings 12 are installed between the outer wall of the rotating shaft 4 and the end cap 10, and between the outer wall of the rotating shaft 4 and the bobbin, to prevent the lubricating oil in the bearing cavity 9 from leaking.

[0021] An electric slide rail 13 along the axial direction of the bobbin is installed in the slot 2. An electric slider 14 is installed on the electric slide rail 13. A thread-passing ring 15 is provided on the electric slider 14. The yarn passes through the thread-passing ring 15. The electric slider 14 reciprocates along the electric slide rail 13 to guide the wound yarn.

[0022] When installing the winding shaft 7 of the present utility model, the distance between the two eccentric rollers 6 at each end is the largest. At this time, the two ends of the winding shaft 7 can be respectively placed between the two eccentric rollers 6 at both ends. Then, the eccentric rollers 6 are driven to rotate. The distance between the eccentric rollers 6 at the same end gradually decreases, and the eccentric rollers 6 gradually clamp the winding shaft 7. During the process of clamping the winding shaft 7, the arc-shaped groove 8 on the winding shaft 7 will automatically fit with the outer wall of the eccentric roller 6, thereby automatically realizing the axial positioning of the winding shaft 7. At the same time, since the eccentric roller 6 is in a waist shape, the winding shaft 7 will be automatically pushed to the position with the smallest diameter of the eccentric roller 6 during the clamping process, realizing the height positioning of the winding shaft 7.

[0023] After the winding shaft 7 is clamped by the eccentric rollers 6, the driving motor of the rotating shaft 4 is started. The rotating shaft 4 drives the turntable 3 to rotate, and then drives the eccentric rollers 6 and the winding shaft 7 to rotate for winding the yarn. When the winding is completed, the eccentric rollers 6 rotate in reverse to release the winding shaft 7, and then the winding shaft 7 can be taken off and a new winding shaft 7 can be replaced.

[0024] After the winding shaft 7 of the present utility model is installed and clamped, the axial locking and positioning of the winding shaft 7 can be realized through the arc-shaped groove 8, which can prevent the winding shaft 7 from axially moving. Through the waist shape of the eccentric roller 6, the automatic positioning of the height of the winding shaft 7 can be realized, so that the positioning and locking of the winding shaft 7 can be quickly and automatically completed, and the operation of installing and removing the winding shaft 7 is simple, improving the installation and removal efficiency of the winding shaft 7.
