Description

Technical Field

[0001] This utility model relates to the field of guide wheel technology, specifically a yarn guide wheel structure with a self-cleaning groove. Background Technology

[0002] A yarn guide roller is a component used in textile machinery to guide the movement of yarn. It typically consists of one or more rotating wheels with smooth or textured surfaces to ensure that the yarn can pass smoothly and steadily during high-speed movement, reducing friction and wear and preventing yarn breakage or deformation.

[0003] A yarn guide wheel structure with a self-cleaning groove is a component in textile machinery used to guide yarn and automatically clean yarn impurities. This type of guide wheel adds a self-cleaning groove to the traditional yarn guide wheel. By designing a special groove shape structure, the yarn is guided to automatically carry fiber debris, dust and other impurities attached to the surface of the guide wheel into the cleaning groove during the movement, thereby achieving an automatic cleaning function.

[0004] While existing yarn guide wheel structures have the function of cleaning yarn, static electricity is indeed generated during the friction between the guide wheel and the yarn. This is because the friction between the yarn and the guide wheel leads to the transfer of electrons, thereby generating static charge on the surface of the yarn and the guide wheel. This causes dust to be attracted to the grinding wheel, increasing the maintenance frequency of the guide wheel. Therefore, a yarn guide wheel structure with a self-cleaning groove is proposed to address the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0027] Please see Figures 1-6 This utility model provides a technical solution:

[0028] A yarn guide wheel structure with a self-cleaning groove includes a fixed frame 1, a shaft hole 2 at the lower end of the fixed frame 1, a roller assembly 3 rotatably connected to the inner side of the shaft hole 2, a guide wheel assembly 4 fixedly connected to one end of the roller assembly 3, the roller assembly 3 including a cylindrical roller 31, a ball bearing 32 fixedly connected to the outer side of the cylindrical roller 31, a flow channel 33 opened on the inner side of the cylindrical roller 31, a vortex blade 38 fixedly connected to the inner side of the flow channel 33 opened on the cylindrical roller 31, and a guide wheel assembly 4 including a guide wheel body 41, a dirt collection groove 42, a through hole 43 and an opening 45 opened on the inner side of the guide wheel body 41, a cleaning annular groove 46 opened near the middle of the guide wheel body 41, nylon strips 44 fixedly connected to the left and right ends of the cleaning annular groove 46 opened on the guide wheel body 41, and both the left and right sides of the guide wheel body 41 fixedly connected to the cylindrical roller 31.

[0029] As a further implementation of this solution, the inner side of the shaft hole 2 of the fixed frame 1 is fixedly connected to the outer side of the ball bearing 32. The fixed frame 1 is rotatably connected to the roller 31 through the ball bearing 32. Through the above arrangement, this connection method allows the roller 31 to rotate flexibly, while ensuring the stability of the rotation, reducing the wear and breakage risk of the yarn caused by the shaking of the guide wheel during the guiding process, and improving the guiding accuracy and quality of the yarn.

[0030] As a further implementation of this solution, a waste discharge port 34 is provided on the inner side of the roller 31, and the flow channel 33 is connected to the waste discharge port 34. Through the above arrangement, the connection design between the flow channel 33 and the waste discharge port 34 provides a channel for air flow inside the guide wheel, so that an effective airflow can be formed when the guide wheel rotates. The electrostatic adsorption impurities on the surface of the guide wheel are removed by wind-driven airflow, reducing the maintenance frequency of the guide wheel and improving production efficiency.

[0031] As a further implementation of this solution, an arch frame 35 is fixedly connected to the outside of the roller 31, and a spring telescopic rod 36 is fixedly connected to one side of the arch frame 35. A rubber plug 37 is fixedly connected to the end of the spring telescopic rod 36 away from the arch frame 35. The rubber plug 37 is conical in shape, and the outside of the rubber plug 37 fits against the inside of the discharge port 34. The flow channel 33 opened in the roller 31 is connected to the opening 45. The center of the roller 31 and the center of the guide wheel body 41 are on the same horizontal line. With the above settings, when the yarn is drawn out, the guide wheel body 41 and the roller assembly 3 can be driven to rotate simultaneously, so that the roller assembly 3 and the guide wheel assembly 4 form a gas flow channel, providing a path for cleaning impurities. At the same time, during maintenance, the discharge port 34 can be automatically blocked, improving the concentration force during water flushing and facilitating the cleaning of impurities on the inner wall of the roller 31 and the guide wheel body 41.

[0032] As a further implementation of this solution, the through hole 43 is connected to the cleaning annular groove 46 and the impurity collection groove 42. One end of the nylon strip 44 is fitted to the inner side of the cleaning annular groove 46 opened in the guide wheel body 41. A rubber sleeve 47 is fixedly connected to the inner side of the cleaning annular groove 46 opened in the guide wheel body 41. Through the above-mentioned arrangement, this connection and fitting structure design allows the yarn to fully contact the nylon strip 44 when passing through the cleaning annular groove 46. The nylon strip 44 can effectively clean the impurities on the surface of the yarn during the deformation process. At the same time, the fixed connection of the rubber sleeve 47 further guides the direction of the yarn, ensuring that the yarn remains clean and stable during the guiding process.

[0033] Workflow: When guiding the yarn, the yarn lead-out end passes through the cleaning annular groove 46 opened in the guide wheel body 41. During this process, the yarn will contact the nylon strip 44 and simultaneously adhere the yarn to the upper end of the rubber sleeve 47. Then, the yarn is led out. When the yarn passes through, the friction between the yarn and the rubber sleeve 47 will drive the rubber sleeve 47 and the guide wheel body 41 to rotate. The guide wheel body 41 is rotatably connected to the shaft hole 2 opened in the fixing frame 1 through the ball bearing 32, which can reduce the friction when the guide wheel body 41 rotates, and at the same time reduce the friction between the yarn and the rubber sleeve 47. When the yarn passes through, the passing yarn will contact the nylon strip 44, and the nylon strip 44 will deform. The nylon strip 44 cleans the debris and dust impurities on the yarn, thereby achieving the function of cleaning the yarn surface.

[0034] When removing dust and debris from the surface of the guide roller, the same principle applies. When the roller 31 rotates, it drives the vortex blade 38 to rotate. The vortex blade 38 guides the airflow. At this time, the external air enters the through hole 43 through the cleaning annular groove 46, and then enters the flow channel 33 through the through hole 43, the impurity collection groove 42 and the opening 45. It flows out through the impurity discharge port 34. During the rotation of the roller 31, the rubber plug 37 is squeezed by the spring telescopic rod 36 due to centrifugal force. The rubber plug 37 moves away from the impurity discharge port 34, and the impurities flow out from the impurity discharge port 34 and are cleaned by the existing vacuum cleaner. At this time, the impurities on the surface of the guide roller body 41 and the nylon strip 44 will flow with the airflow, which significantly reduces the impurities on the surface of the guide roller. This not only improves the cleaning effect on the yarn, but also reduces the frequency of guide roller maintenance.

[0035] When impurities adhere to the inner walls of the roller 31 and the guide wheel body 41 and need to be removed, the roller 31 is connected to the water pipe inside. At this time, the roller 31 needs to be stationary. Under the action of the elastic force of the spring telescopic rod 36, the rubber plug 37 is pushed into the discharge port 34. The rubber plug 37 blocks the discharge port 34. At this time, water will enter the opening 45, the collection tank 42, and the inner side of the guide wheel body 41 through the flow channel 33, and flow out through the other end of the guide wheel body 41. Through the effect of water flushing, the impurities on the inner walls of the roller 31 and the guide wheel body 41 are cleaned.

[0036] Based on the above principles, when guiding the yarn, the device can clean impurities on the yarn surface while simultaneously cleaning impurities adsorbed by electrostatic force on the guide wheel surface through wind-driven airflow. This improves the continuous cleaning effect on the yarn and reduces the frequency of guide wheel maintenance.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
