Description

Technical Field

[0001] The utility model relates to the technical field of textile devices, in particular to a yarn inserting spindle device. Background Art

[0002] The insert spindle is a special part of a spinning machine or a doubling machine. It is used in conjunction with the warp tube to twist the fiber into yarn and wind it into a certain shape. For example, the existing doubling machine is equipped with an insert spindle on the frame. When doubling, two or three warp tubes are inserted into the insert spindle respectively, and then the single yarn is led to the doubling machine for doubling. Usually, the scale of a spinning mill is expressed by the number of insert spindles. The more insert spindles on the machine, the higher the spinning efficiency.

[0003] However, there are still some shortcomings when placing warp tubes on conventional yarn insertion spindles. For example, when the standard warp tube models are different or customized warp tubes are used, the inner and outer diameters of the warp tubes are different, and the inner wall of the warp tube cannot be completely fitted with the support rod of the yarn insertion spindle. When the machine is working at high speed, the warp tube cannot be stably fixed on the yarn insertion spindle. The instability of the warp tube leads to increased tension during spinning, an increase in yarn breakage, and further causes yarn skipping and unhooking, affecting production efficiency. Utility model patent CN210621036U discloses a yarn insertion spindle with a bobbin fixing function, including two upper and lower symmetrical fixing rods, a support rod and a yarn insertion mechanism. There are two support rods in total, and the two support rods are symmetrically welded between the two fixing rods. Multiple yarn insertion mechanisms are evenly spaced on one side of the two support rods. This patent provides a fixed block on the outside of the yarn insertion spindle. The fixed block cooperates with the elastic pad to fix the yarn tube. The yarn tube can be pulled out from the fixed block by sliding the fixed block down. However, the fixed block has a unique size and cannot be used to fix warp yarn tubes with different inner and outer diameters. In addition, the structure of the yarn insertion spindle is complex and lacks versatility. Utility Model Content

[0004] In view of the technical problem in the prior art that a yarn inserting spindle is difficult to fix to warp yarn tubes with different inner and outer diameters, the utility model provides a yarn inserting spindle device with a simple structure, which can fix warp yarn tubes with different inner and outer diameters and has strong versatility.

[0005] The technical solution of this utility model is as follows:

[0006] A yarn inserting spindle device comprises a yarn inserting spindle base, which is fixedly connected to a yarn inserting spindle support rod and is in a convex shape. A slidable yarn inserting spindle base sleeve is respectively provided on the left and right sides of the yarn inserting spindle base, and a fixing bolt is provided on the yarn inserting spindle base sleeve; a rotating shaft is also provided on the yarn inserting spindle base, and a yarn inserting spindle core is fixedly connected to the rotating shaft, an anti-slip component is provided on the top of the yarn inserting spindle core, one end of the rotating shaft is fixedly connected to a connecting rod, and the other end of the connecting rod is hinged to an interlocking pull rod.

[0007] Furthermore, the bottom diameter of the yarn-inserting spindle support rod is 10 - 15 mm.

[0008] The bottom diameter of the yarn-inserting spindle support rod is smaller than the bottom inner diameter of the warp beam tube commonly used.

[0009] Furthermore, the height by which the yarn-inserting spindle base sleeve protrudes above the upper surface of the yarn-inserting spindle base is 5 - 10 mm.

[0010] Furthermore, the maximum distance between the side of the yarn-inserting spindle base sleeve near the yarn-inserting spindle support rod and the axis of the yarn-inserting spindle support rod is 30 - 32.5 mm.

[0011] Furthermore, the length of the yarn-inserting spindle core is 20 - 25 mm.

[0012] Furthermore, the anti-slip component is rubber.

[0013] When the anti-slip component contacts the inner wall of the warp beam tube, it will deform, resulting in an increase in the frictional force between the anti-slip component and the inner wall of the warp beam tube.

[0014] The beneficial effects of the present utility model are as follows:

[0015] The present utility model provides a yarn-inserting spindle device. Slide and fix the yarn-inserting spindle base sleeves on both sides, fit and fix them to the outer wall of the bottom of the warp beam tube. Pull and fix the interlocking pull rod, so that it drives the anti-slip component of the yarn-inserting spindle core to fit and fix to the inner wall of the warp beam tube. The warp beam tube is firmly fixed on the yarn-inserting spindle device through the principle of three-point stability, greatly reducing the problems of difficult tube extraction during doffing and jumping tube and loop-off yarn during spinning, and improving production efficiency.

The bottom diameter of the yarn inserting spindle support rod 2 is 10 mm. A slidable yarn inserting spindle base sleeve 8 is sleeved on each of the left and right sides of the yarn inserting spindle base 1. The height of the yarn inserting spindle base sleeve 8 above the upper surface of the yarn inserting spindle base 1 is 5 mm. The farthest distance from the side of the yarn inserting spindle base sleeve 8 near the yarn inserting spindle support rod 2 to the axis of the yarn inserting spindle support 2 is 30 mm. A fixing bolt 9 is provided on the yarn inserting spindle base sleeve 8; a rotating shaft 5 is further provided on the yarn inserting spindle base 1, and a yarn inserting spindle core 3 is fixedly connected to the rotating shaft 5. And through the rotation of the rotating shaft 5, the yarn inserting spindle core 3 forms an angle of ≤ 90° with the yarn inserting spindle support rod 2. The length of the yarn inserting spindle core 3 is 20 mm. A non-slip member 4 made of rubber is sleeved on the top end of the yarn inserting spindle core 3. One end of the rotating shaft 5 is fixedly connected to a connecting rod 6, and the other end of the connecting rod 6 is hinged to an interlocking pull rod 7.

[0025] There are three fixed contact points between the yarn inserting spindle device and the warp beam 10 (two are the contact points on the opposite sides of the outer wall of the bottom of the warp beam 10 where the yarn inserting spindle base sleeve 8 contacts, and one is the contact point where the non-slip member 4 contacts the inner wall of the warp beam 10). According to the principle of three-point stability, the warp beam 10 is fixed to the yarn inserting spindle device.
