Description

Technical Field

[0001] The utility model relates to the technical field of yarn guide wheels, in particular to an impact-resistant yarn guide wheel made of a multi-layer composite ceramic material. Background Art

[0002] Impact-resistant yarn guide wheels made of multi-layer composite ceramic materials usually refer to yarn guide wheels made of a stack of ceramic materials with different properties and functions. This design can take into account properties such as wear resistance, high temperature resistance, and impact resistance, making the yarn guide wheel have better durability and service life.

[0003] Publication number: CN221274874U, a textile yarn guide wheel, including a yarn guide wheel and a bracket, further comprising: a support tube fixedly mounted on the end of the bracket, the yarn guide wheel connected to the support tube via a fixed bearing; a ball turntable clamped between the yarn guide wheel and the end of the bracket; a mounting bolt, after passing through the support tube, threadedly installed into a mounting groove provided on the bracket; the mounting bolt is provided with an anti-slip sleeve, the anti-slip sleeve being located between the end of the support tube and the bolt head of the mounting bolt. In this textile yarn guide wheel, the right side of the yarn guide wheel is pressed against the ball turntable, and the left side is tightened by multiple rotating balls, so that the yarn guide wheel can only rotate axially and cannot swing, significantly reducing the possibility of the yarn guide wheel shaking, which is beneficial to improving the quality of the core-spun yarn, while also ensuring the stability of the overall structure.

[0004] To sum up, the yarn guide wheel in the prior art CN221274874U can only rotate around the axis and cannot swing, which significantly reduces the possibility of the yarn guide wheel shaking. When the pressure exerted by the yarn on the yarn guide wheel is large, the position of the yarn guide wheel is fixed and cannot be adjusted, resulting in a large friction between the yarn and the yarn guide wheel, which easily accelerates the wear of the yarn guide wheel and also increases the risk of yarn breakage. Utility Model Content

[0005] The purpose of the utility model is to provide an impact-resistant yarn guide wheel made of a multi-layer composite ceramic material, which has the advantages of providing a buffer for the yarn guide wheel body, improving the impact resistance of the yarn guide wheel body, and reducing friction with the yarn, thereby solving the problem that the yarn guide wheel has no cache structure and has high friction with the yarn.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an impact-resistant yarn guide wheel made of a multi-layer composite ceramic material, comprising a base plate, a fixing frame and a brush plate, springs are installed on both sides of the top of the base plate, two fixing sleeves are symmetrically installed on the top of the base plate inside the two springs, two movable rods are symmetrically installed on both sides of the bottom of the fixing frame, the tops of the two fixing sleeves are provided with sockets, the bottoms of the two movable rods are inserted into the two fixing sleeves from the two sockets, bearing 1 is embedded and installed on both sides of the fixing frame, the inner rings of the two bearings 1 are fixedly installed with fixing rods, the yarn guide wheel body is installed on the opposite end of the two fixing rods, a screw hole is provided in the middle of the bottom of the fixing frame, the inner wall of the screw hole is threadedly connected with a screw, and bearing 2 is installed on the bottom of the brush plate.

[0007] When using the impact-resistant yarn guide wheel made of multi-layer composite ceramic material in the present technical solution, the two fixing plates are fixed to the bearing structure through the fixing holes of the two fixing plates using bolts and other tools, and the yarn is placed on the yarn guide wheel body. As the yarn moves, the yarn guide wheel body rotates. When the yarn exerts a large pressure on the yarn guide wheel body, the two springs at the bottom of the fixing frame are compressed under the influence of the pressure to provide buffering. The two movable rods at the bottom of the fixing frame move inside the two fixed sleeves at the top of the bottom plate. The screw is rotated by a handwheel, and the screw rotates and moves in the screw hole at the bottom of the fixing frame. The screw drives the brush plate to rise, so that the brush plate contacts the surface of the yarn guide wheel body. As the yarn guide wheel body rotates, the brush plate cleans the surface of the yarn guide wheel body.

[0008] Preferably, baffles are mounted at the bottom of each of the two movable rods, sliders are mounted on both sides of each baffle, and second slide grooves are formed on both sides of the interior of each of the two fixed sleeves, with the two sets of sliders being slidably connected to the two sets of second slide grooves. The two baffles slide within the second slide grooves within the interior of the two fixed sleeves via the sliders. When the two movable rods are raised or lowered, the two baffles move within the interior of the two fixed sleeves, thereby limiting the movement direction of the fixing brackets at the top of the two movable rods.

[0009] Preferably, the outer diameters of the two baffles are larger than the inner diameters of the top insertion holes of the two fixing sleeves. The two baffles prevent the two movable rods from sliding off from the inside of the two fixing sleeves.

[0010] Preferably, the tops of the two springs are fixedly connected to the bottom of the fixing frame. The fixing frame is elastically connected to the bottom plate via the two springs.

[0011] Preferably, the top of the screw is fixedly connected to the inner ring of the second bearing, and a hand wheel is installed at the bottom of the screw. The screw can be rotated by the hand wheel, and the screw is movably connected to the fixed frame through the second bearing.

[0012] Preferably, slide rods are installed on both sides of the brush plate, and slide grooves 1 are opened on both sides of the fixing frame. The two slide rods are slidably connected to the two slide grooves 1. The two slide rods limit the brush plate, and when the brush plate is raised or lowered, the two slide rods slide in the slide grooves 1 to keep the brush plate stable.

[0013] Preferably, fixing plates are welded on both the front and rear sides of the bottom plate, and both fixing plates are provided with fixing holes. The two fixing plates are fixed to the supporting structure using tools such as bolts through the fixing holes of the two fixing plates.

[0014] Preferably, a distance is left between the hand wheel and the two springs so that the hand wheel will not interfere with the two springs when it is rotated.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model arranges springs and movable rods to place the yarn on the guide wheel body. As the yarn moves, the guide wheel body rotates. When the pressure exerted by the yarn on the guide wheel body is relatively large, the two springs at the bottom of the fixed frame are compressed under the influence of the pressure to provide a buffer. The two movable rods at the bottom of the fixed frame move inside the two fixed sleeves at the top of the bottom plate to limit the moving direction of the guide wheel body, thereby providing a buffer for the guide wheel body, improving the impact resistance of the guide wheel body, and reducing the friction with the yarn.
