[0023] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figure 1-Figure 6 As shown, a weft knitting machine cotton wool cleaning mechanism based on airflow detection and self-cleaning includes a weft knitting machine body 1, which is composed of a mounting frame 11, a yarn feeding mechanism 12, a weaving mechanism 13 and a winding mechanism 14. The yarn feeding mechanism 12 is arranged on the upper part of the mounting frame 11 for providing yarn raw materials, the weaving mechanism is arranged below the yarn feeding mechanism 12 for weaving the yarn, and the winding mechanism 14 is arranged at the bottom of the mounting frame 11 for winding the woven finished product, and also includes an airflow detection component 2 and a cleaning component 3. The airflow detection component 2 is mounted on the mounting frame 11. The cleaning assembly 3 includes a circular track 31, a walking device 32 and a cleaning device 33. The circular track 31 is fixed to the periphery of the mounting frame 11. The diameter of the circular track 31 is larger than the outer diameter of the mounting frame 11, and is used to provide a walking track for the walking device 32. The walking device 32 is installed on the circular track 31, and is used to drive the cleaning device 33 to walk along the circular track 31. The cleaning device 33 is installed on the side of the walking device 32 away from the mounting frame 11, and is used to clean the cotton wool on the weft knitting machine body 1.

[0025] The working process of the weft knitting machine can be basically divided into several major steps, such as the yarn feeding mechanism 12 feeding yarn, the weaving mechanism 13 weaving, and then the weaved finished product is reeled in by the reeling mechanism 14. In this process, cotton wool is easily generated, which affects the normal operation of the machine. Therefore, several main structures need to be cleaned to improve production efficiency; cotton wool gradually accumulates during the production process. According to environmental protection and energy saving considerations, it is not necessary to keep the cleaning component 3 turned on. It is necessary to use the airflow detection component 2 to monitor the airflow state inside the weft knitting machine in real time. According to the structure and airflow characteristics inside the weft knitting machine, select suitable airflow detection equipment, such as wind speed sensor, pressure sensor, temperature sensor, etc., and connect the sensor to the data acquisition system to realize real-time data transmission and storage. The data acquisition system should have efficient and stable data processing capabilities, be able to process data from multiple sensors at the same time, and process and analyze the collected airflow data in real time to extract key airflow feature information, such as wind speed, pressure, temperature, etc. At the same time, the data analysis software can be used to visualize the airflow data to help operators more intuitively understand the airflow state inside the weft knitting machine. Finally, based on the real-time monitored airflow data, the weft knitting machine can be cleaned of cotton wool.

[0026] like Figure 4 and Figure 5 As shown, the walking device 32 includes a walking frame 321, a mounting groove is provided at the bottom of the walking frame 321, an auxiliary wheel 322 is installed in the mounting groove, the auxiliary wheel 322 is used to contact the surface of the circular track 31, a walking motor 323 is installed on the top of the walking frame 321, the output shaft of the walking motor 323 passes through the walking frame 321 and is installed with a driving wheel 324, the driving wheel 324 is adapted to the track groove in the circular track 31, and a shell 325 is also installed on the surface of the walking frame 321, and the walking motor 323 is installed inside the shell 325.

[0027] The main function of the walking device 32 is to drive the cleaning device 33 to clean the cotton wool around the periphery of the weft knitting machine. The device forms a displacement along the circular track 31 by rotating the driving wheel 324 at the output shaft end of the walking motor 323 in the track groove in the circular track 31, and helps the walking frame 321 to move smoothly through the auxiliary wheel 322; at the same time, the shell 325 plays a role in protecting the walking motor 323 and facilitating the installation of the cleaning device 33. Designing the walking device 32 can reduce the installation of multiple cleaning devices 33, saving the production and manufacturing cost of the cotton wool cleaning mechanism of the weft knitting machine.

[0028] like Figure 3-Figure 5As shown, the cleaning device 33 includes a fan bin 331, and a powerful exhaust fan and a cotton wool storage chamber are installed inside the fan bin 331. A connecting frame 332 is fixed to the outer wall of the fan bin 331, and the connecting frame 332 is used to connect with the outer shell 325 of the training group device. An upper cotton wool suction tube 333 is installed on the top of the fan bin 331, and the end of the upper cotton wool suction tube 333 is parallel to the yarn feeding mechanism 12. A lower cotton wool suction tube 334 is installed on one side of the fan bin 331, and the end of the lower cotton wool suction tube 334 is parallel to the weaving mechanism 13. A moving wheel 335 is installed at the bottom of the fan bin 331 for assisting the fan bin 331 to move on the circular track 31. An air outlet is provided at the lower part of the side of the fan bin 331 away from the lower cotton wool suction tube 334.

[0029] The upper cotton wool suction pipe 333 and the lower cotton wool suction pipe 334 of the cleaning device 33 are both connected to the air inlet end of the powerful exhaust fan, which uses a motor as a power source to provide the required power for the operation of the machine. When the motor is started, the current generates a magnetic field, causing the motor rotor to rotate, thereby driving the fan blades to rotate. The fan blades generate wind force under the action of the air, forming a low-pressure area, so that the outside air is sucked into the machine. This part usually includes components such as an air suction port, an air suction motor, and an air filter. The cotton wool sucked into the fan compartment 331 will be stored in a cotton wool storage room, and the operator needs to clean the cotton wool storage room regularly. The powerful fan in the cleaning device 33 and the motor that provides power for walking both use a rechargeable mobile power supply as a power source.

[0030] like Figure 1-Figure 3 , Figure 6 As shown, a rotating fan 15 is installed on the top of the mounting frame 11 for maintaining airflow of the weft knitting machine body 1 when the machine is working. The airflow detection assembly 2 includes a sensing bin 21, and a wind speed sensor and an airflow pressure sensor are arranged inside the sensing bin 21. An airflow duct 22 is installed through the bottom of the sensing bin 21, and a plurality of airflow collecting ports 23 are arranged at the bottom of the airflow duct 22 for collecting the internal airflow when the weft knitting machine is working.

[0031] The airflow data inside the weft knitting machine is collected through the airflow collecting port 23 and transmitted to the wind speed sensor and airflow pressure sensor inside the sensing bin 21 through the airflow duct 22. By comparing the airflow parameters under normal working conditions, the algorithm can accurately determine whether the accumulation of cotton wool has reached the level that requires cleaning.

[0032] like Figure 1-Figure 3 , Figure 6As shown, the airflow detection component 2 also includes a mounting column 24, which is mounted at the bottom of the sensing bin 21. Off-axis motors 25 are mounted on both sides of the mounting column 24. The output shaft of the off-axis motor 25 is connected to a shaft 26. One end of the shaft 26 is connected to a cleaning tube 27. The cleaning tube 27 is sleeved on the outer wall of the airflow duct 22, and the bottom inner wall of the cleaning tube 27 is matched with the airflow collecting port 23. The cleaning tube 27 is connected to the bottom of the mounting column 24 through a reset spring 28.

[0033] To prevent the airflow collection port 23 from being blocked by cotton wool, the cleaning tube 27 can slide up and down along the airflow duct 22 at regular intervals through the interaction of the eccentric motor 25 and the return spring 28, and clean the airflow collection port 23 while sliding, so that the airflow collection port 23 remains unobstructed during operation, thereby collecting the most accurate airflow parameters.

[0034] like Figure 3 As shown, a finished product lint-clearing device 4 is installed at the bottom of the mounting frame 11 on one side of the winding mechanism 14, and an exhaust fan and a lint storage chamber are installed inside the finished product lint-clearing device 4.

[0035] The device can effectively clean the cotton wool adhered to the surface of the finished woven product before being rolled up, thereby improving the quality of the finished woven product, and can further reduce the cotton wool content inside the weft knitting machine, thereby reducing the malfunction rate of the weft knitting machine.

[0036] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
