Description

Technical Field

[0001] This utility model relates to the field of yarn winding machine technology, and in particular to an automatic yarn threading and winding device. Background Technology

[0002] In the yarn production process of the textile industry, the threading and winding processes of the winnowing machine are crucial to the quality and efficiency of the finished yarn. In traditional processes, threading and winding of yarn largely rely on manual operation, requiring workers to separate, wrap, and knot each yarn individually. This is not only labor-intensive but also inefficient, processing only 10-15 bundles of yarn per minute, which is insufficient for large-scale production. Furthermore, manual operation is susceptible to fatigue, leading to uneven yarn bundling and weak wrapping, resulting in quality problems such as loose yarn and loose knots.

[0003] While existing automated devices attempt to replace manual labor, they suffer from drawbacks such as complex structures and poor adaptability. For example, some devices use mechanical claws for yarn separation, but the inability to precisely control the separation force results in a yarn damage rate as high as 15%. Winding mechanisms also often lack negative pressure adsorption designs, leading to poor yarn end intake and affecting winding efficiency. Therefore, there is an urgent need to develop an integrated device that can automatically separate, wind, and knot yarn to improve the automation level of winnowing machines and the quality of yarn production. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic yarn threading and winding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic yarn threading and winding device includes a main body of a winnowing machine. A yarn separating mechanism, a winding mechanism, a cycloidal mechanism, and a bird's head knotting mechanism are arranged on one side of the main body. The yarn separating mechanism includes two hook-shaped yarn separators and a drive assembly. The winding mechanism includes a circular hollow steel tube and a connector, which are fixedly connected. A synchronous motor is fixedly connected to the top of the connector. The cycloidal mechanism includes a cycloidal body, a oscillating drive component, and a yarn clamping assembly. The bird's head knotting mechanism is used for knotting and cutting the yarn bundle.

[0007] Preferably, the drive assembly includes a cylinder and a linkage mechanism, and the hook-type splitter achieves synchronous up-and-down movement through the linkage mechanism.

[0008] Preferably, the circular hollow steel pipe has an arc-shaped open end with a guide slope. The main body of the winch is fixedly connected to a fan, and the fan is fixedly connected to a negative pressure air outlet pipe, which is connected to the hollow cavity of the circular hollow steel pipe.

[0009] Preferably, the wire clamping assembly includes an elastic clamp and a wire clamping drive, wherein the elastic clamp is used to clamp the wire bundle and swing with the cycloidal body.

[0010] Preferably, the bird-head knotting mechanism includes a bird-head-shaped knotting component and scissors, the scissors being used to cut the yarn.

[0011] The beneficial effects of this utility model are as follows:

[0012] The hook-shaped yarn separator with a yarn-separating mechanism separates the yarn under the drive of the drive component. The circular hollow steel tube of the winding mechanism is driven by a synchronous motor and the negative pressure of the fan is applied through the negative pressure air outlet pipe to suck in the yarn head and complete the winding, thus replacing manual operation and improving production efficiency.

[0013] The guide slope of the circular hollow steel pipe facilitates the intake of the thread end, the elastic clamp of the cycloidal mechanism holds the thread bundle and swings with the cycloidal body to avoid insufficient thread length when winding, and the scissors of the bird head knotting mechanism complete the cutting to ensure the quality of yarn bundling.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-3An automatic yarn threading and winding device includes a winnowing machine body 1. A yarn separating mechanism, a winding mechanism, a cycloidal mechanism, and a bird-head knotting mechanism are arranged on one side of the winnowing machine body 1. The yarn separating mechanism includes two hook-shaped yarn separators 2 and a drive assembly. The winding mechanism includes a circular hollow steel pipe 3 and a connector 4. The connector 4 and the circular hollow steel pipe 3 are fixedly connected. A synchronous motor 5 is fixedly connected to the top of the connector 4. The cycloidal mechanism includes a cycloidal body, a oscillating drive component, and a yarn clamping assembly. The bird-head knotting mechanism is used for knotting and cutting the yarn bundle. The hook-shaped yarn separators 2 of the yarn separating mechanism are used to separate the yarn under the drive of the drive assembly. The circular hollow steel pipe 3 of the winding mechanism is driven by the synchronous motor 5 and the negative pressure of the fan is applied through the negative pressure air outlet pipe 6 to draw in the yarn end and complete the winding, replacing manual operation and improving production efficiency.

[0020] In this utility model, the driving component includes a cylinder 8 and a linkage mechanism. The hook-type splitter 2 moves up and down synchronously through the linkage mechanism. The driving component is limited to a cylinder and a linkage mechanism, so that the hook-type splitter can move up and down synchronously, ensuring the consistency and stability of the splitting action.

[0021] The circular hollow steel pipe 3 has an arc-shaped opening end with a guide slope. The main body 1 of the winch is fixedly connected to a fan, and the fan is fixedly connected to a negative pressure air outlet pipe 6. The negative pressure air outlet pipe 6 is connected to the hollow cavity of the circular hollow steel pipe 3. This indicates that the circular hollow steel pipe has a guide slope at the arc-shaped opening end, and the fan is connected to the hollow cavity through the negative pressure air outlet pipe. The negative pressure is used to more smoothly suck in the wire end to complete the winding.

[0022] The wire clamping assembly includes an elastic clamp and a wire clamping drive. The elastic clamp is used to hold the wire bundle and swing with the cycloidal body. It is noted that the wire clamping assembly is composed of an elastic clamp and a wire clamping drive. The elastic clamp holds the wire bundle and swings with the cycloidal body to avoid insufficient wire bundle length when winding.

[0023] The bird-head knotting mechanism includes a bird-head-shaped knotting component and scissors 7. The scissors 7 are used to cut the yarn. The bird-head knotting mechanism includes a bird-head-shaped knotting component and scissors. The scissors are used to cut the yarn, realizing the functions of knotting and cutting the yarn bundle.

[0024] Working Principle: In the idle area of ​​this device, all the components mentioned above, which refer to structural parts, are connected. The specific connection method should refer to the working principle below, and the connection between each component is completed in the order of operation. The detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and will not explain it again. When the main body 1 of the winnowing machine is running, when the yarn reaches a certain amount, the cylinder 8 in the drive component drives the two hook-shaped yarn dividers 2 to move downward through the linkage mechanism to divide the yarn into bundles. At the same time, the scissors 7 on both sides of the equipment extend to cut the yarn. The fan generates negative pressure in the circular hollow steel pipe 3 through the negative pressure air outlet pipe 6 to suck in the yarn end. The synchronous motor 5 drives the connector 4 to rotate the circular hollow steel pipe 3 so that the bundle wraps around the yarn twice. The elastic clamp of the cycloidal mechanism holds the bundle and swings with the cycloidal body to extend the bundle from the coil to avoid insufficient yarn length. Finally, the bird head-shaped knotting part of the bird head knotting mechanism completes the knotting. The scissors 7 cut the yarn, completing the entire process of automatic threading and winding.

[0025] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
