Description
Technical Field
[0001] This utility model relates to the field of texturing machine technology, specifically a rapid yarn changing device driven by a single spindle in a texturing machine. Background Technology
[0002] Texturing machines are important pieces of equipment in the textile machinery field, mainly used for processing polyester and nylon filaments. Each spindle is equipped with an independent drive motor or mechanism. Through the control system, the drive mechanism is activated to remove the yarn bobbin after the yarn has been used up and quickly replace it with a new yarn bobbin. In this process, the single-spindle drive can precisely control the movement of the yarn bobbin, ensuring the accuracy and stability of the yarn changing action.
[0003] During yarn processing, a large number of impurities inevitably adhere to the surface of the yarn bobbin, such as fiber fuzz, short yarns, dust, and even dried material formed by sizing residue. These impurities not only affect the smoothness and tension stability of the yarn winding, leading to an increase in yarn breakage rate and product defect rate, but also transfer with the yarn bobbin during yarn changing, contaminating the new yarn or clogging the yarn guide components of the texturing machine. Therefore, a fast yarn changing device driven by a single spindle of the texturing machine is needed. Utility Model Content
[0004] The purpose of this invention is to provide a fast yarn changing device driven by a single spindle of a texturing machine, which solves the problems mentioned in the background art.
[0005] This application provides a single-spindle driven quick yarn changing device for a texturing machine, including a base. Two fixed plates and a support plate are fixedly connected to the top of the base. The support plate is located between the two fixed plates. Vertical plates are fixedly connected to the top of each of the two fixed plates. A horizontal plate is fixedly connected between the two vertical plates. A second electric push rod is fixedly inserted through the horizontal plate. A mounting bracket is fixedly connected to the end face of the piston rod of the second electric push rod. A rubber cylinder is rotatably connected inside the mounting bracket. A motor is fixedly connected to one outer wall of the mounting bracket. The output shaft of the motor passes through the mounting bracket and is fixedly connected to one end of the rubber cylinder. A connecting plate is fixedly connected to one outer wall of the horizontal plate. A first electric push rod is fixedly inserted through the connecting plate. A scraper is fixedly connected to the end face of the piston rod of the first electric push rod.
[0006] In operation, the second electric push rod is activated, and its piston rod pushes the mounting frame downward, bringing the rubber tube on the mounting frame into contact with the yarn bobbin. Then, the output shaft of the motor drives the rubber tube to rotate, utilizing the elastic friction properties of the rubber material to quickly peel off the fibers, dust, and other impurities adhering to the surface of the yarn bobbin. After cleaning, the rubber tube returns to its original position, and the piston rod of the first electric push rod pushes the scraper to contact the outer wall of the rubber tube. Together with the motor rotating the rubber tube, it can scrape off the impurities adsorbed on the surface of the rubber tube. Once the rubber tube is cleaned, the frequency converter driver of the motor starts, and its output shaft drives the yarn bobbin to start rotating, performing yarn winding at a set linear speed. Throughout the entire process, the actions of each component are coordinated in sequence by the PLC control system to ensure seamless connection between the cleaning and winding processes, significantly improving the operating efficiency of the equipment.
[0007] Optionally, a motor is fixedly connected to the outer wall of the fixing plate, the output shaft of the motor passes through the fixing plate and is fixedly connected to a yarn bobbin, and the yarn bobbin and the support plate are rotatably connected by a rotating shaft.
[0008] By adopting the above technical solution, the output shaft of the motor can drive the yarn drum to rotate, thereby completing the winding of the yarn.
[0009] Optionally, the outer wall of the rubber cylinder is provided with protrusions.
[0010] By adopting the above technical solution, the protrusion can increase the friction between the rubber tube and the yarn tube, further improving the effect of removing impurities from the yarn tube.
[0011] Optionally, the scraper has a V-shaped edge facing the rubber cylinder.
[0012] By adopting the above technical solution, the effect of the scraper in removing impurities adsorbed on the rubber cylinder is further improved, thus realizing the cleaning of the rubber cylinder.
[0013] Optionally, a guide rod is fixedly connected between the two fixing plates, and the guide rod is located on one side of the yarn bobbin.
[0014] By adopting the above technical solutions, the tension of the yarn can be increased, and the yarn can be prevented from becoming loose.
[0015] Optionally, the scraper is made of rubber.
[0016] By adopting the above technical solution, excessive wear of the rubber cylinder by the scraper can be avoided, thus extending its service life.
[0017] Optionally, two motors are provided, and each motor is electrically connected to the PLC control system through an independent relay module.
[0018] By adopting the above technical solution, the independent control requirements in the single-spindle drive mode can be met. When a yarn bobbin needs to be replaced, simply turn off the switch of the motor at the corresponding spindle position, and the other motor will continue to operate normally.
[0019] Optionally, the vertical cross-section of the connecting plate is an inverted L-shaped structure.
[0020] By adopting the above technical solution, the scraper can be installed horizontally, which increases the contact area between the scraper and the rubber cylinder.
[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:
[0022] The technical solution of this application uses the piston rod of the second electric push rod to push the mounting frame down, so that the rubber tube on the mounting frame contacts the yarn tube. Then, the output shaft of the motor drives the rubber tube to rotate. Utilizing the elastic friction characteristics of the rubber material, the fiber fuzz, dust and other impurities attached to the surface of the yarn tube are quickly peeled off. After cleaning, the rubber tube is reset. The piston rod of the first electric push rod can push the scraper to contact the outer wall of the rubber tube. With the motor rotating the rubber tube, the impurities adsorbed on the surface of the rubber tube can be scraped off, making cleaning convenient and quick. Attached Figure Description
