Furthermore, the oil storage grooves and the yarn guide are an integrated structure, eliminating the need for periodic replacement of the oiling structure and making it convenient to use.

Description

Technical Field

[0001] This utility model relates to the field of yarn guides, and in particular to a ceramic yarn guide for spinning. Background Technology

[0002] In the textile industry, a spinning machine is a device used to spin fibrous materials into yarn. As an indispensable accessory in the spinning machine, the yarn guide mainly plays the functions of guiding and gathering yarn. The yarn guiding function of the yarn guide is very important. During the spinning process, the fibrous material needs to be guided by the yarn guide and pass through various parts of the machine along a specific path to ensure that the fiber smoothly enters the rotating part of the spinning machine.

[0003] When fibers pass through the guide at high speed, friction is generated. The existing solution is to install an oil nozzle on the guide. The oil forms a lubricating film, which reduces the coefficient of friction between the fiber and the guide surface and prevents damage to the fiber surface (such as fuzz or breakage).

[0004] Chinese Utility Model Patent Publication No. CN 205241873 U discloses a textile oiling guide, including a guide body, characterized in that: the guide body is a cylindrical body with an arc groove, and an oiling guide groove is provided on the guide body; the oiling guide groove has a square cross-section, and an inlet is provided on its upper side; oil spray nozzles are provided on both the left and right sides of the oiling guide groove, and an oil drain hole is provided at the bottom; an oiling layer is provided in the entire oiling guide groove, and the oiling layer includes a sponge and a fiber cloth.

[0005] Existing oiling methods generally employ either direct injection from nozzles or contact oiling with an oil layer. Direct injection from nozzles results in poor oiling performance, easily leading to over- or under-oiling and waste. Contact oiling with an oil layer, on the other hand, causes friction between the spinning yarn and the oil layer (sponge or fiber cloth) during the oiling process, which can easily damage the spinning surface. Furthermore, the oil layer can wear down over time due to friction, requiring regular replacement, which is inconvenient. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a ceramic yarn guide for spinning to solve the problems existing in the background art.

[0007] This utility model provides the following technical solution: a ceramic guide for spinning, including a guide body made of ceramic material, which is in the shape of a right trapezoid. A V-shaped groove for spinning is provided on the front of the guide body. The V-shaped groove includes side baffles on both sides and a bottom wall. Multiple oil storage grooves are provided on the surface of the bottom wall. Oil is provided in the oil storage grooves for oiling the spinning fibers.

[0008] Preferably, an oil hole is provided at the top of the V-shaped groove, and an oil drain groove is provided at the bottom of the V-shaped groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. The guide wire of this utility model is made of pure ceramic material. The spinning wire is guided through the V-shaped groove. When the spinning wire passes through, it comes into contact with the oil in the oil storage tank, thereby wetting the spinning surface and reducing the coefficient of friction between the spinning wire and the surface of the guide wire.

[0018] 2. This utility model replaces the traditional direct oil spraying and oil layer contact oiling by opening an oil storage groove on the main body of the ceramic material yarn guide.

Detailed Implementation

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0025] This utility model provides a ceramic yarn guide for spinning, such as Figure 1-4 As shown, the device includes a guide body 10, which is made of ceramic material and has a right-angled trapezoidal shape. A V-shaped groove 20 is provided on the front of the guide body for the spinning process. The V-shaped groove 20 includes side baffles 201 on both sides and a bottom wall 202. Multiple oil storage grooves 40 are arranged at equal intervals on the surface of the bottom wall 202. Oil is provided in the oil storage grooves 40 for oiling the spinning process.

[0026] The guide wire of this application is made of pure ceramic material. The spinning wire is guided through the V-shaped groove 20. When the spinning wire passes through, it comes into contact with the oil inside the oil storage tank 40, thereby wetting the spinning surface and reducing the coefficient of friction between the spinning wire and the surface of the guide wire.

[0027] This application replaces the traditional direct-injection oiling and contact-type oiling with an oil nozzle by opening an oil storage groove 40 on the ceramic material guide body 10. This not only improves the uniformity of oiling the spinning process but also avoids unnecessary friction on the spinning process. Furthermore, the oil storage groove 40 and the guide body 10 are an integral structure, eliminating the need for periodic replacement of the oiling structure and making it convenient to use.

[0028] In this embodiment, an oil hole 30 is provided at the top of the V-groove 20, and an oil nozzle hole 301 for assembling an oil injector is opened on the back of the oil hole 30. The oil nozzle hole 301 is connected to the oil hole 30. An oil drain groove 50 is provided at the bottom of the V-groove 20. The oil injector sprays oil from the oil hole 30. Under the action of gravity, the oil slides down the bottom wall 202 until it enters the oil storage tank 40. Excess oil is discharged along the oil drain groove 50 and enters the collection tank to realize the recycling of oil.

[0029] In this embodiment, the bottom wall 202 includes a vertical surface 2021, a first inclined surface 2022, and a second inclined surface 2023. The oil storage tank 40 is disposed on the vertical surface 2021, the oil hole 30 is disposed on the first inclined surface 2022, and the oil discharge tank 50 is disposed on the second inclined surface 2023. The sprayed oil flows along the first inclined surface 2022 onto the vertical surface 2021 and enters the oil storage tank 40. Excess oil is discharged along the second inclined surface 2023. The first inclined surface 2022 is used to ensure that the oil flows slowly to improve the stability of the oil flow, and the second inclined surface 2023 ensures that excess oil slides down and is discharged under gravity.

[0030] Furthermore, an arc-shaped chamfer is provided at one end of the first inclined surface 2022 and at the connection with the vertical surface 2021, and an arc-shaped chamfer is also provided at one end of the second inclined surface 2023 and at the connection with the vertical surface 2021. The arc-shaped chamfer helps to prevent scratches on the spinning process.

[0031] In this embodiment, a cavity 70 is provided below the oil nozzle hole 301. The cavity 70 has a right-angled trapezoidal shape to reduce the overall weight of the wire guide.

[0032] In this embodiment, at least one heat dissipation groove 60 is provided on both sides of the yarn guide body 10. The heat dissipation groove 60 is concave. As the spinning time increases through the yarn guide, it generates a certain amount of heat. The heat dissipation groove 60 is used to increase the contact area between the outer surface of the yarn guide and the outside world, thereby improving the heat dissipation effect of the yarn guide.

[0033] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
