Description

Technical Field

[0001] The utility model relates to the technical field of wire doubling machines, and particularly relates to a wire doubling machine anti-line-off device. Background Art

[0002] In the working process of the existing doubling machine, the yarn may break when it is doubling. After the yarn breaks, the yarn needs to be rewound manually, and the doubling machine needs to be shut down, which reduces the working efficiency of the doubling machine. The existing Chinese utility model with the announcement number "CN210854763U" and the patent name "Anti-threading device for doubling machine" discloses an anti-threading device for doubling machine, which can fix the broken thread ends in time when the yarn breaks, saving the time of rewinding the workers and improving the working efficiency. However, the anti-threading device clamps the yarn by the wire claw. Although this method can prevent the yarn from falling off, there is a large friction between the yarn and the wire claw. During the doubling process, the friction between the yarn and the wire claw makes it easier to break the yarn, which will also cause frequent shutdowns. Therefore, a new anti-threading device for doubling machine is needed. Utility Model Content

[0024] A wire-docking machine anti-wire-off device comprises a wire-docking machine body 1, a wire-docking roller 2 is arranged on the wire-docking machine body 1, two groups of support frames 3 are arranged on one side of the wire-docking machine body 1, and winding posts 4 are respectively arranged on the two groups of support frames 3. The wire in the wire-docking machine body 1 passes through the two winding posts 4 and is then wound around the wire-docking roller 2. The winding posts 4 are provided with a clamping post 5 on the side through which the wire passes, and the clamping post 5 and the winding post 4 clamp the wire.

[0025] Furthermore, the two winding poles 4 are respectively a first winding pole 4 away from the winding roller 2 and a second winding pole 4 close to the winding roller 2, the axes of the first winding pole 4, the second winding pole 4 and the winding roller 2 are arranged in parallel, and the wire of the winding machine body 1 passes through the top of the first winding pole 4 and the bottom of the second winding pole 4.

[0026] Furthermore, the support frame 3 is provided with sliding grooves 6 on both sides of the clamping column 5, and sliding blocks 7 are provided in the sliding grooves 6. The two ends of the clamping column 5 are connected to the sliding blocks 7. The side of the sliding block 7 facing away from the winding column 4 is provided with an elastic member, and the elastic member is fixedly connected to the sliding block 7 and the support frame 3 respectively, and the elastic member includes a spring 8.

[0027] Further, fixing plates 9 are provided at the bottoms of the two sets of support frames 3. A driving mechanism is connected to the bottom of the fixing plate 9, and the driving mechanism drives the fixing plate 9 to reciprocate axially along a direction parallel to the coiling roller 2. The driving mechanism includes a lead screw 10 rotatably connected to the body 1 of the wire coiling machine. The bottom of the fixing plate 9 is fixedly connected to the nut of the lead screw 10 of the lead screw 10. One end of the lead screw 10 is drivingly connected to a motor. A guide rod 11 is fixedly arranged on one side of the body 1 of the wire coiling machine where the lead screw 10 is located. The guide rod 11 is arranged parallel to the lead screw 10, and the fixing plate 9 is slidably connected to the guide rod 11. An installation groove 12 is formed in the body 1 of the wire coiling machine, and both the lead screw 10 and the guide rod 11 are installed in the installation groove 12.

[0028] Further, a wire feeding roller 13 is arranged on one side of the body 1 of the wire coiling machine where the two winding columns 4 are away from the coiling roller 2.
