Description

Technical Field

[0001] The utility model relates to the technical field of two-for-one twisters, in particular to a clamping head device of a two-for-one twister. Background Art

[0002] A two-for-one twister is a twisting device, also called a doubling machine. It is mainly used to bond two or more single yarns into strands by twisting, so as to enhance the performance of the original yarn and meet customer needs. The two-for-one twister has the characteristics of increased winding capacity, 10,000 meters without joints, greatly improved twisting quality, and lower layer height. It is particularly suitable for operation. The two-for-one twister can achieve two twists in one turn, and the twisting efficiency is doubled compared with traditional twisting equipment. This equipment is mainly used in chemical fiber two-for-one twisters, direct twist two-for-one twisters, sewing thread special two-for-one twisters and other fields. In the two-for-one twister, the clamping device is a mechanism used to drive the yarn guide head to achieve left and right reciprocating motion. It is usually installed on the yarn guide rod. Its main function is to guide the yarn into the bobbin to help complete the twisting process.

[0003] In the actual production process, the chuck device will be subjected to strong vibration and impact load, which may cause the yarn guide chuck to slip and deflect, affecting the equipment performance and yarn quality. For this reason, we proposed a chuck device for a two-for-one twister. Utility Model Content

[0028] See also Figure 1-4 A chuck device of a two-for-one twisting machine includes a bracket 1 and a support arm 2. Both ends of the bracket 1 are fixedly connected with the support arms 2. The two support arms 2 and the bracket 1 form a U shape. The lower ends of the two support arms 2 are provided with a chuck device 3. The chuck device 3 includes a mounting sleeve 4, a rotating structure 5, a mounting member 7 and a support head 10.

[0029] Two mounting sleeves 4 are symmetrically fixed and plugged into the lower end of the support arm 2 to provide a mounting housing;

[0030] The rotating structure 5 is located at one side of the mounting sleeve 4 and is used to push and pull the mounting member 7;

[0031] A mounting member 7, movably inserted into the mounting sleeve 4, for mounting the support head 10;

[0032] The support head 10 is arranged on the mounting member 7 and is used for clamping the yarn bobbin.

[0033] Furthermore, the installation sleeve 4 is a hollow circular cylinder, and one side of the installation sleeve 4 is an open structure.

[0034] Furthermore, two symmetrically arranged sliding grooves 6 are provided on the arc-shaped side surface of the installation sleeve 4 .

[0035] Furthermore, the mounting member 7 is movably inserted in the mounting sleeve 4 , and the two sliding grooves 6 corresponding to the side of the mounting member 7 close to the arc-shaped inner wall of the mounting sleeve 4 are fixedly connected to the limiting blocks 9 , and the two limiting blocks 9 are movably inserted in the sliding grooves 6 .

[0036] Furthermore, the rotating structure 5 includes a threaded rod 8, a rotating handle 13 and a limiting ring 14. The threaded rod 8 is fixedly connected to the side of the mounting member 7 away from the opening of the mounting sleeve 4, and the other end of the threaded rod 8 extends to the outer side of the mounting sleeve 4 and is threadedly connected to the rotating handle 13. The rotating handle 13 extends from the side close to the mounting sleeve 4 to the inner cavity of the mounting sleeve 4 and is fixedly connected to an integrated limiting ring 14.

[0037] Furthermore, three slots 15 equidistantly arranged in a ring shape are provided on the side of the mounting member 7 away from the threaded rod 8, and rotating recessed holes 16 are provided on the inner walls on both sides of the three slots 15. A rotating rod 11 is rotatably connected in the rotating recessed holes 16, and a support head 10 is fixedly connected to the side of the rotating rod 11.

[0038] Furthermore, a spring 12 is fixedly connected to one end of the upper surface of the support head 10 corresponding to the inner wall of the slot 15 , and the other end of the spring 12 is in contact with the inner wall of the mounting sleeve 4 .

[0039] Working principle: When the device is needed to clamp the yarn bobbin, first place the yarn bobbin between the two clamping devices 3, and rotate the rotating handles 13 of the clamping devices 3 at both ends at the same time. By rotating the rotating handles 13, the threaded rod 8 moves toward the yarn bobbin, and the threaded rod 8 moves to push the mounting member 7 to move toward the yarn bobbin. The limit blocks 9 at both ends of the mounting member 7 can prevent the mounting member 7 from moving excessively under the restriction of the sliding groove 6, resulting in the spring 12 attached to the mounting member 7 being unable to be retracted; when the mounting member 7 moves, the support head 10 is driven to move outward by the rotating rod 11. When the three support heads 10 move to the entrance of the yarn tube, they are squeezed by the yarn tube, and the outer ends of the three support heads 10 shrink inward. At the same time, the inner ends of the three support heads 10 lift up and squeeze the spring 12 around the support heads 10 accordingly. When the support heads 10 completely enter the yarn tube, the spring 12 releases the elastic force, and the outer ends of the support heads 10 are clamped in the yarn tube. During operation, the vibration or impact of the yarn tube on the clamping device 3 is converted into the elastic force of the spring 12 or the rotational force of the rotating rod 11 through the support head 10, so as to reduce the displacement and deflection of the clamping device 3.
