Description

Technical Field

[0001] The utility model relates to the technical field of texturing machines, in particular to a wire guide for texturing machines. Background Art

[0002] A texturing machine is a textile machine that can process untwisted yarns such as polyester into elastic yarns with medium elasticity and low elasticity through false twisting. Among the various devices of the texturing machine, the wire guide is used to change the direction of travel of the filaments so that the filaments can accurately enter the false twister to ensure the normal operation of the texturing machine.

[0003] The currently published patent: CN214243267U discloses a wire guide mechanism of a texturing machine winding device. The filament contacts the guide wheel, which guides the filament. Since the guide wheel can rotate on a fixed plate, the friction between the filament and the guide wheel is small, thereby ensuring the quality of the filament after winding.

[0004] Based on the above search, it was found that the above patent has the following problems when in use: when in use, the guide mechanism can make the guide wheel rotate on the fixed plate through the contact between the filament and the guide wheel, thereby reducing the friction between the filament and the guide wheel. However, when the processed filament is rolled up on the paper roll, the texturizing machine will automatically drop the roll. At this moment, the filament tension is prone to large fluctuations, which can easily cause the filament to fall off the wire guide. The staff is also required to manually put the filament into the wire guide again, affecting the normal operation of the texturizing machine. Utility Model Content

[0005] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a wire guide for a texturing machine, which can solve the problem that when the processed filaments are wound on the paper tube, the texturing machine automatically drops the tube, and the filament tension is prone to large fluctuations at this moment, which makes it easy for the filaments to fall off the wire guide.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wire guide for a texturing machine, comprising a wire frame and a yarn anti-slipping mechanism; a rotating rod is fixedly connected to the surface of the wire frame, a wire wheel is rotatably sleeved on the surface of the rotating rod, and an annular groove is provided on the surface of the wire wheel; the yarn anti-slipping mechanism comprises a support block, a sliding rod, a pull ring, a pressure block and a spring, the support block is fixedly connected to the surface of the wire frame, the sliding rod is slidably sleeved on the inside of the support block, the pull ring is rotatably connected to the upper end of the sliding rod, the pressure block is fixedly connected to the lower end of the sliding rod, a rolling ball is installed on the surface of the pressure block, the rolling ball contacts the inner wall of the annular groove, the spring is slidably sleeved on the surface of the sliding rod, the upper end of the spring is fixedly connected to the bottom of the support block, and the lower end of the spring is fixedly connected to the top of the pressure block.

[0007] Preferably, two slide grooves are provided on the surface of the lead frame, and sliders are slidably connected inside the two slide grooves.

[0008] Preferably, guide rods are slidably sleeved inside the two sliding blocks, and the two guide rods are fixedly connected to the inside of the two sliding grooves respectively.

[0011] Preferably, the surfaces of the two sliding blocks are fixedly connected with rotating shafts, and the surfaces of the two rotating shafts are rotatably sleeved with rotating wheels.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The texturing machine uses a wire guide, and the wire wheel rotates and drives the ball to roll inside the pressure block. At this time, the pressure block can be used to protect the fiber line to prevent the fiber line from escaping from the surface of the wire wheel, thereby ensuring the normal operation of the texturing machine.

[0024] See also Figure 1-4 The utility model provides a technical solution: a wire guide for a texturing machine, comprising a wire frame 1 and a yarn anti-slipping mechanism, the surface of the wire frame 1 is fixedly connected with a rotating rod 2, the surface of the rotating rod 2 is rotatably sleeved with a wire wheel 3, the surface of the wire wheel 3 is provided with an annular groove 4, the yarn anti-slipping mechanism comprises a support block 5, a slide bar 6, a pull ring 7, a pressure block 8 and a spring 9, the support block 5 is fixedly connected to the surface of the wire frame 1, the slide bar 6 is slidably sleeved with the inside of the support block 5, the pull ring 7 is rotatably connected to the upper end of the slide bar 6, the pressure block 8 is fixedly connected to the lower end of the slide bar 6, a rolling ball 10 is installed on the surface of the pressure block 8, the rolling ball 10 contacts the inner wall of the annular groove 4, the spring 9 is slidably sleeved on the surface of the slide bar 6, the upper end of the spring 9 is fixedly connected to the bottom of the support block 5, and the lower end of the spring 9 is fixedly connected to the top of the pressure block 8.

[0025] Two slide grooves 11 are provided on the surface of the lead frame 1, and sliders 12 are slidably connected inside the two slide grooves 11, and guide rods 13 are slidably sleeved inside the two sliders 12. The two guide rods 13 are respectively fixedly connected to the inside of the two slide grooves 11, and compression springs 14 are slidably sleeved on the surfaces of the two guide rods 13. The lower ends of the two compression springs 14 are respectively fixedly connected to the tops of the two sliders 12, and the upper ends of the two compression springs 14 are respectively fixedly connected to the top walls of the two slide grooves 11. The surfaces of the two sliders 12 are fixedly connected to rotating shafts 15, and the surfaces of the two rotating shafts 15 are rotatably sleeved with rotating wheels 16.

[0026] When the guide wire is in use, the fiber line is stuck on the surface of the two rotating wheels 16 and passes through the guide wheel 3 and is stuck in the inside of the annular groove 4. When the guide wire moves, the friction between the guide wheel 3 and the guide wheel 3 can drive it to rotate on the surface of the rotating rod 2. The spring 9 pushes the pressure block 8 to slide downward and drives the ball 10 to squeeze on the inner wall of the annular groove 4. The guide wheel 3 rotates and drives the ball 10 to roll inside the pressure block 8. At this time, the pressure block 8 can be used to protect the fiber line to prevent the fiber line from escaping from the surface of the guide wheel 3, thereby ensuring the normal operation of the texturizing machine. When the staff needs to take out or put in the fiber line from the side of the guide wheel 3, the staff can drive the slide bar 6 to slide the pressure block 8 upward to slide off the surface of the guide wheel 3 through the pull ring 7.

[0027] When the fiber line moves on the surface of the two rotating wheels 16, the fiber line squeezes the two rotating wheels 16 and drives them to move upward. The two rotating wheels 16 move and drive the two sliders 12 to slide upward through the two rotating shafts 15 to squeeze the two compression springs 14. At this time, the two compression springs 14 push the two rotating wheels 16 to slide downward and make the fiber line in a tensioned state. When the processed filaments are rolled up on the paper tube, the texturizing machine automatically drops the tube. When the filament tension fluctuates greatly, the two compression springs 14 can immediately release the elastic force and push the two sliders 12 to slide downward. The downward sliding of the two sliders 12 can drive the two rotating wheels 16 to slide downward through the two rotating shafts 15 to press the fiber line, thereby making the fiber line tensioned again. By adjusting the upper and lower positions of the two rotating wheels 16, the fiber line is always in a tensioned state, ensuring the tightness of the fiber line wrapped around the surface of the paper tube.

[0028] Working principle: the wire guide of the texturing machine, the fiber line is stuck on the surface of the two rotating wheels 16 and passes through the wire wheel 3 and is stuck in the inside of the annular groove 4. The spring 9 pushes the pressure block 8 to slide downward and drives the ball 10 to squeeze the inner wall of the annular groove 4. The wire wheel 3 rotates and drives the ball 10 to roll inside the pressure block 8. At this time, the pressure block 8 can be used to protect the fiber line to prevent the fiber line from escaping from the surface of the wire wheel 3. When the fiber line moves on the surface of the two rotating wheels 16, the fiber line squeezes the two rotating wheels 16 and drives it to move upward. The two rotating wheels 16 move and drive the two sliders 12 to slide upward through the two rotating shafts 15 to squeeze the two compression springs 14. When the processed filaments are rolled up on the paper tube, when the filament tension fluctuates greatly, the two compression springs 14 can immediately release the elastic force and push the two sliders 12 to slide downward. The two sliders 12 slide downward and can drive the two rotating wheels 16 to slide downward through the two rotating shafts 15 to press the fiber line, thereby making the fiber line tensioned again.

[0029] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
