DETAILED DESCRIPTION

[0023] The utility model will be further described in detail below in combination with examples.

[0024] In specific implementation: as Figs. 1 to 4 shown, an automatic labeling device for a filament bobbin of a viscose filament spinning machine, comprising a label printing mechanism 1 and a labeling mechanism 2, the labeling mechanism 2 includes a labeling arm 21 that can reciprocate along the axial direction of the bobbin, the labeling arm 21 has the ability to reciprocate along the axial direction of the bobbin, so that the device can extend into the paper tube during the labeling process to attach the label, the front end of the labeling arm 21 is provided with a label palm assembly 22 and a rotary driver 23, the rotary driver 23 is fixedly installed at the front end of the labeling arm 21 through a vertical plate, the rear end of the labeling arm 21 is slidingly connected on a linear guide rail 24, through the cooperation of the label palm assembly 22 and the rotary driver 23, the labeling process becomes more stable and controllable. The label palm assembly 22 helps to accurately adsorb the label, and the rotary driver 23 ensures that the suction cup 221 can accurately rotate and attach the label, thereby ensuring the accuracy and firmness of label attachment. In specific implementation, the rotary driver 23 is a swing air cylinder.

[0025] The label palm assembly 22 includes a suction cup 221, the suction cup 221 is connected with the output shaft of the rotary driver 23 through a rotary plate 25, the lower end of the suction cup 221 has an arc-shaped adsorption surface, a plurality of air suction holes 222 that are in communication with a vacuum cavity are formed on the adsorption surface, the vacuum cavity of the suction cup 221 is communicated with an external air source through an air pipe joint 26, and the label printing mechanism 1 is located on one side of the labeling mechanism 2.

[0026] The coordinate positioning system ensures accurate label pasting. When the rear end of the labeling arm 21 approaches the rear end of the linear guide rail 24, the suction cup 221 is located at the label output position of the label printing mechanism 1 and rotates under the drive of the rotary driver 23 to adsorb the label at the output position.

[0027] When the rear end of the labeling arm 21 approaches the front end of the linear guide rail 24, the suction cup 221 extends into the inner hole of the filament tube to apply the label.

[0028] In implementation, the linear guide 24 is a rodless cylinder. The advantage of using a rodless cylinder as the linear guide 24 lies in its simple structure, stability, and ease of control. The slider on the rodless cylinder is connected to the rear end of the labeling arm 21. A front buffer 241 and a rear buffer 242 are provided at both ends of the rodless cylinder facing the slider. When the rear side of the slider abuts against the rear buffer 242, the suction cup 221 is directly opposite the label dispensing position of the label printer. Combined with the design of the front and rear buffers 242, the smooth movement and accurate positioning of the labeling arm 21 during the labeling process can be ensured. When the front side of the slider abuts against the front buffer 241, the suction cup 221 is located at the labeling position and applies the label to the inner wall of the paper tube.

The spring 27, installed between the top of the suction cup 221 and the rotating plate 25, provides the suction cup 221 with a certain degree of elasticity. This design allows the suction cup 221 to adapt to the inner walls of paper tubes of different shapes and sizes. Through the elastic action of the spring 27, the suction cup 221 can better conform to the inner wall surface, thereby...

[0030] In practice, foam 28 is attached to the bottom of suction cup 221. This foam 28 design provides additional cushioning and protection for the labeling device. The softness of the foam 28 reduces friction and collision between suction cup 221 and the inner wall of the paper tube, improving the stability and reliability of the labeling process.
