This mechanism realizes the batch cutting of yarns mechanically, aiming to improve the cutting efficiency and accuracy of yarns during the warping process, reduce manual operations, and ensure the length consistency of yarn cutting. This device can be applied to a warping machine to help cut different lengths of yarns in batches, meeting the requirements of large-scale textile production.

[0003] The published patent No. CN210132541U discloses an automatic yarn cutting device, which includes a scale, a yarn guiding baffle, a tool holder blade assembly, a linear driving mechanism, a base, a yarn winding pin and a mounting plate. The scale and the base are mounted on the mounting plate. The yarn winding pin is fixedly connected with a connecting plate A, and the connecting plate A is mounted on the mounting plate. The yarn guiding baffle is placed on the mounting plate and fixedly connected with the base. The yarn guiding baffle is provided with a guiding groove for guiding when fixing the yarn. The linear driving mechanism is fixedly connected with the base, and the moving part of the linear driving mechanism is fixedly connected with the tool holder blade assembly through a connecting plate B.

Especially when the yarn is not tightened, the failure rate during the cutting process is relatively high, and the operator needs to manually adjust the tension state of the yarn, increasing the complexity and labor intensity of manual operations and reducing the production efficiency. Therefore, improvement is needed. Summary of the Utility Model

[0022] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification. Embodiment

[0024] Please refer to Figures 1-5, the present utility model provides a technical solution: a batch mechanical cutting mechanism for yarn of a warping machine, including a workbench 1. A yarn guiding baffle 12 is fixedly installed on the top surface of the workbench 1. The yarn guiding baffle 12 can be fixed on the top surface of the workbench 1 by bolts or welding. This installation method is not only firm but also convenient for later maintenance and replacement. A passing groove 13 is opened on the top surface of the yarn guiding baffle 12. The structure of the passing groove 13 can be processed by cutting or milling to ensure the accuracy of the groove and the smooth passing of the yarn 14. The yarn 14 is arranged in the passing groove 13, and the movement of the yarn 14 interferes with that of the cutter 5 to realize the cutting of the yarn 14. A base 2 is fixedly installed on the top surface of the workbench 1. The base 2 is of a hollow structure. The base 2 can be connected to the workbench 1 by bolts or snap connections to ensure stable installation and facilitate subsequent maintenance.

[0025] Please refer to Figures 1-5 , an installation top plate 3 is fixedly installed on the surface of the base 2. The installation top plate 3 is fixed to the base 2 by bolt connection. Such a connection method can not only ensure the strength of the equipment but also facilitate the transportation or disassembly of the equipment. A cylinder 4 is fixedly installed on the top surface of the installation top plate 3. The cylinder 4 is connected to the installation top plate 3 through a flange to ensure the stability of the cylinder 4 under high-pressure operation. A cutter 5 is installed at the output end of the cylinder 4. The material of the cutter 5 can be selected as high-strength alloy steel to ensure sufficient hardness and wear resistance during the cutting process. A side plate 6 is fixedly installed on the side of the cutter 5. A sliding rod 7 penetrates through the top surface of the side plate 6. The sliding rod 7 is slidably connected to the side plate 6 through a bearing or a sliding sleeve to ensure small friction and stable operation during sliding. A top block 8 is fixedly installed at one end of the sliding rod 7. The top block 8 is made of high-strength material to ensure that it can withstand sufficient pressure during the cutting process. A soft pad 9 is fixedly installed at the other end of the sliding rod 7. The material of the soft pad 9 can be selected as polyurethane or silicone, which can not only protect the yarn 14 from being crushed during cutting but also enhance the fixing effect of the yarn 14. A semi-circular groove 11 is opened on the bottom surface of the soft pad 9. The processing method of the semi-circular groove 11 can adopt precision turning or casting process to ensure that the shape of the groove fits well with the yarn 14. A tension spring 10 is fixedly installed between the top block 8 and the side plate 6. The tension spring 10 is made of spring steel material and has good anti-fatigue performance, and can maintain stable elasticity after long-term use. The function of the tension spring 10 is to pull the top block 8 downward, so that the sliding rod 7 and the soft pad 9 press the yarn 14, thereby ensuring that the yarn 14 always remains taut during the cutting process and avoiding cutting failure. Embodiment

[0026] Please refer to Figures 4-5, a maintenance mechanism is provided on the top surface of the cutting knife 5. The maintenance mechanism includes a vertical rod 15, which is fixedly installed on the top surface of the cutting knife 5. The vertical rod 15 can be fixed by welding or bolt connection to ensure that it is not easily loosened during high-frequency operations. A connecting block 16 is fixedly installed at the top end of the vertical rod 15. The connecting block 16 is connected to the vertical rod 15 by bolts or welding to ensure stability. A square frame 17 is fixedly installed on the side surface of the connecting block 16. The square frame 17 is installed by means of a buckle or bolts, which is convenient for disassembly and replacement. A friction pad 18 is fixedly installed inside the square frame 17. The material of the friction pad 18 is sponge or other flexible materials, which can effectively remove dust and fiber impurities on the surface of the air cylinder 4. The friction pad 18 is attached to the surface of the air cylinder 4, and the automatic cleaning function of the surface of the air cylinder 4 is realized through the downward pressing movement of the vertical rod 15.

[0027] Working principle: The yarn 14 is placed on the trough 13. When it is necessary to cut the yarn 14, the cylinder 4 is opened. At this time, the cylinder 4 can drive the cutter 5 to move downward. When the cutter 5 moves downward, the yarn 14 can be cut. At the same time, when the cutter 5 moves downward, it can also drive the soft pad 9 to move downward. The semi-circular groove 11 under the soft pad 9 can press the yarn 14 at this time, and the yarn 14 can be fixed at this time. In this way, when the cutter 5 cuts downward, it can avoid the failure of cutting caused by the yarn 14 not being tightened. At the same time, due to the action of the pulling force, the tension spring 10 can pull the top block 8 downward. The top block 8 can then drive the sliding rod 7 to move downward. The sliding rod 7 can then drive the soft pad 9 to press the yarn 14, which can ensure the firm fixation of the yarn 14. Through the combined structure of the soft pad 9 and the semi-circular groove 11, the present utility model can fix the yarn 14 simultaneously when the cutter 5 presses downward, ensuring that the yarn 14 will not loosen or move during the cutting process, avoiding cutting failure caused by the yarn 14 not being tightened, improving the cutting accuracy and consistency. At the same time, by using the automatic downward pressing action of the cylinder 4 and the linkage design of the tension spring 10, the entire cutting process is more automated, reducing manual intervention, lowering the labor intensity, and improving the production efficiency. When the cutter 5 presses downward, the tension spring 10 and the top block 8 are linked to drive the sliding rod 7 and the soft pad 9 to press downward, further enhancing the fixing effect of the yarn 14 and ensuring that the yarn 14 remains in a taut state throughout the cutting process, avoiding incomplete cutting or cutting failure. When the cutter 5 moves downward, the cutter 5 can drive the vertical rod 15 to move downward. The vertical rod 15 can then drive the connecting block 16 and the square box 17 to move downward. At this time, the square box 17 can drive the friction pad 18 to rub the surface of the cylinder 4, and the surface of the cylinder 4 can be cleaned at this time. In this way, when cutting the yarn 14, the cylinder 4 can be maintained synchronously. When the cutter 5 presses downward to cut the yarn 14, the vertical rod 15 is linked to drive the friction pad 18 to clean the surface of the cylinder 4, realizing the function of automatically maintaining the cylinder 4 during the cutting operation process, avoiding the accumulation of dust or fiber impurities on the surface of the cylinder 4, thereby prolonging the service life of the cylinder 4. At the same time, the surface of the cylinder 4 is automatically cleaned by the friction pad 18, reducing the maintenance frequency of the equipment, avoiding equipment failures or performance degradation caused by the surface pollution of the cylinder 4, improving the long-term stability and working reliability of the equipment. At the same time, the synchronous cleaning function reduces the need for manual regular cleaning of the equipment, improves the production efficiency, reduces the frequency of equipment shutdown for maintenance, and saves time and labor costs.

[0028] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
