Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery accessories, in particular to a textile machinery rabbit head. Background Art

[0002] The texturing machine is a post-processing device for polyester filament yarn. The grooved drum box on the texturing machine ensures the proper formation of the DTY yarn during production, while the reciprocating yarn guide is a key mechanism for ensuring the formation of the DTY yarn cakes during the texturing machine. Because its cross-section resembles a rabbit's head, it is also called the spinning machine rabbit head. It is widely used in the textile industry, particularly in yarn and cable production. It plays a vital role in the cotton, wool, and silk textile industries. The quality and performance of the spinning machine rabbit head directly impact yarn quality and production efficiency. Its primary function is to guide and stabilize the yarn, preventing it from falling off or straying from the winding path.

[0003] The existing scimitar-shaped rabbit head accessories mainly include a plastic body, a ceramic wire guide and a counterweight metal sheet embedded in the plastic body through a compression molding process. The ceramic wire guide is inserted into the end of the plastic body and then bonded with glue. Although the bonding strength of the glue is very high, even exceeding the strength of the plastic body itself, ensuring the stability of the connection, it also brings the problem that the wire guide cannot be disassembled. In actual use, the scimitar-shaped rabbit head is often deformed due to the deformation of the plastic body, while the high-strength and wear-resistant ceramic wire guide has no problem. Half of the cost of the accessory is actually on the ceramic wire guide. Therefore, when the plastic part is deformed, the wire guide cannot be disassembled, and the entire accessory can only be scrapped, which increases the loss cost of consumables and has further room for improvement. Utility Model Content

[0004] 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 spinning machine rabbit head to solve the above problem.

[0005] To achieve the above-mentioned purpose, a textile machinery rabbit head is provided, comprising a plastic body and a ceramic wire guide, a counterweight chamber being provided at one end of the plastic body, a counterweight metal sheet being provided inside the counterweight chamber, a scimitar arm being provided at the end of the plastic body away from the counterweight chamber, an axial hole being provided at the plastic body between the counterweight chamber and the scimitar arm, a mounting sleeve being provided at the end of the scimitar arm away from the plastic body, a ceramic wire guide being inserted into the interior of the mounting sleeve, and two limiting holes being provided at one end of the ceramic wire guide embedded in the mounting sleeve, screw mounting holes being provided at positions corresponding to the two limiting holes on both sides of the mounting sleeve, two mounting screws being provided through the four screw mounting holes, a hexagonal limiting groove being provided at positions corresponding to the two screw mounting holes on the outer wall of one side of the mounting sleeve, and hexagonal nuts being provided inside the two hexagonal limiting grooves.

[0006] According to the textile machinery rabbit head, the position of the shaft hole corresponds to the overall center of gravity position of the rabbit head.

[0007] According to the textile machinery rabbit head, the two limiting holes are arranged longitudinally along the plugging direction on the ceramic wire guide.

[0008] According to the textile machinery rabbit head, the two mounting screws are both threadedly connected with the corresponding hexagonal nuts after passing through the corresponding limiting holes and screw mounting holes.

[0009] According to the textile machinery rabbit head, the shape of the counterweight metal sheet corresponds to the shape of the counterweight chamber, and the material of the counterweight metal sheet is galvanized iron sheet.

[0010] According to the textile machine rabbit head, a wire groove is provided in the middle of the ceramic wire guide.

[0011] The above solution has at least one of the following beneficial effects:

[0012] Compared with the prior art, the utility model changes the original adhesive fixing method between the plastic part main body and the ceramic wire guide to a fixed connection method through two screws, so that the plastic part main body and the ceramic wire guide can be detached. Therefore, when the rabbit head accessory is scrapped, the ceramic wire guide with low wear degree can be removed and only the low-cost plastic part can be scrapped. By reusing the ceramic wire guide and the fixing screws, the scrapping cost of the rabbit head accessory can be greatly reduced, thereby enhancing the practicality of the device.

[0013] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
