Description

Technical Field

[0001] This utility model belongs to the technical field of yarn pulling devices, and particularly relates to a yarn pulling device for a doffing machine. Background Technology

[0002] A doffing machine is a mechanical device in the textile industry used to automatically remove full tubes of yarn from a spinning machine and replace them with empty tubes. The doffing machine's yarn pulling device is responsible for pulling the full tubes of yarn from the spindle, ensuring that the yarn pulling action is completed without damaging the yarn and spindle, thus laying the foundation for subsequent tube changing and winding processes.

[0003] Most existing doffing machine yarn pulling devices are limited to a single yarn pulling function. After completing the yarn pulling operation, the empty yarn tube is often manually inserted into the doffing machine for subsequent yarn binding. This not only increases the complexity and labor intensity of manual operation, but also reduces the overall production efficiency. Therefore, an improvement is needed. To this end, a doffing machine yarn pulling device is proposed. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution:

[0027] A doffing machine yarn pulling device includes a horizontal frame 1, a frame 2 fixedly installed on the side of the horizontal frame 1, a frame 3 fixedly installed on the side of the frame 2, two symmetrical electric push rods 4 fixedly installed inside the horizontal frame 1, a movable plate 5 disposed inside the frame 2, the output shafts of the two sets of electric push rods 4 are slidably mounted on the frame 2, and the ends of the output shafts of the two sets of electric push rods 4 are respectively fixedly mounted to the ends of the movable plate 5, two symmetrical electric push rods 6 fixedly installed inside the frame 2, a movable plate 7 disposed inside the frame 3, the output shafts of the two sets of electric push rods 6 are slidably mounted on the frame 3, and the ends of the output shafts of the two sets of electric push rods 6 are respectively fixedly mounted to the ends of the movable plate 7, a horizontal plate 8 is disposed below the horizontal frame 1, and vertical tubes 9 are evenly distributed on the horizontal plate 8.

[0028] When in use, the horizontal frame 1 is fixedly installed on the doffing carriage or on the movable element, the horizontal plate 8 and the vertical tube 9 are installed on the doffing carriage parallel to the horizontal frame 1, and empty yarn tubes are placed on the vertical tube 9.

[0029] Before the doffing trolley is pushed to doff the yarn, drive frame 2 3 to the top of the empty yarn tube. Electric push rod 2 6 inside frame 2 3 starts to work. Its output shaft pulls movable plate 2 7 to move, so that movable plate 2 7 clamps the empty yarn tube on vertical tube 9. When the doffing operation is performed, drive frame 1 2 to the top of the yarn tube. Electric push rod 1 4 inside frame 1 2 works. Its output shaft pulls movable plate 1 5 to move. Movable plate 1 5 clamps the full yarn tube and feeds the yarn. After the feeding is completed, movable plate 2 7 moves the clamped empty yarn tube to the corresponding position and inserts the empty yarn tube into the doffing machine.

[0030] This doffing machine yarn pulling device not only has the function of pulling yarn, but also can automatically insert yarn tubes after pulling yarn, effectively improving production efficiency. The overall structure of the device is simple and highly practical.

[0031] A pad is laid on frame 1 2, frame 2 3, movable plate 1 5, and movable plate 2 7, and the pad is made of rubber.

[0032] The rubber pad has a certain degree of flexibility and friction. On the one hand, it can increase the friction between the pad and the yarn tube, making the yarn tube more stable during clamping and less prone to slippage. On the other hand, the rubber pad can protect the yarn tube, preventing the surface of the yarn tube from being scratched or damaged due to hard contact during clamping, thereby ensuring the quality of the yarn tube and its subsequent use.

[0033] A mounting frame 10 is snapped onto one side of the horizontal plate 8;

[0034] The mounting frame 10 is installed on the side of the doffing trolley, and the horizontal plate 8 is snapped onto the mounting frame 10 on one side. During long-term doffing operations, the horizontal plate 8 may be damaged for various reasons or need to be replaced according to different production needs. When the horizontal plate 8 needs to be replaced, since the horizontal plate 8 is snapped onto the mounting frame 10, the old horizontal plate 8 can be easily removed by simply separating the horizontal plate 8 from the mounting frame 10. Then, the new horizontal plate 8 is installed onto the mounting frame 10 in the same snapping manner, which simplifies the operation process of replacing the horizontal plate 8, saves replacement time, and improves the convenience of equipment maintenance.

[0035] A mounting plate 11 is snapped onto the horizontal plate 8, and the vertical tube 9 is mounted on the mounting plate 11.

[0036] When it is necessary to replace the vertical tube 9, the mounting plate 11 can be separated from the snap-fit ​​on the horizontal plate 8 first, and then the vertical tube 9 on the mounting plate 11 can be replaced or maintained. After the operation is completed, the mounting plate 11 can be snapped back onto the horizontal plate 8, which realizes the convenient replacement of the vertical tube 9 and ensures the normal operation of the yarn pulling device of the doffing machine.

[0037] The bottom end of the vertical pipe 9 is threadedly connected to the mounting plate 11;

[0038] The bottom end of the vertical tube 9 is threaded to the mounting plate 11, which facilitates the individual replacement or adjustment of the vertical tube 9.

Its output shaft pulls movable plate 2 7 to move, so that movable plate 2 7 clamps the empty yarn tube on vertical tube 9. When the doffing operation is performed, drive frame 1 2 to the top of the yarn tube. Electric push rod 1 4 inside frame 1 2 works. Its output shaft pulls movable plate 1 5 to move. Movable plate 1 5 clamps the full yarn tube and feeds the yarn. After the feeding is completed, movable plate 2 7 moves the clamped empty yarn tube to the corresponding position and inserts the empty yarn tube into the doffing machine.
