Detailed Description

The technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

The utility model provides an unwinding mechanism of a labeling machine, which is shown in figures 1 to 4 and comprises a sleeve 10, a rotating shaft 20, a tension bar 30 and a spring 40; the two ends of the sleeve 10 are provided with positioning plates 11, the sleeve 10 is provided with a plurality of through grooves 12, and the through grooves 12 extend along the axial direction of the sleeve 10; the rotating shaft 20 is rotatably connected between the two positioning plates 11, the peripheral side of the rotating shaft 20 is provided with a plurality of planes 21 and arc surfaces 22, and the planes 21 and the arc surfaces 22 are alternately arranged around the peripheral side of the rotating shaft 20; the plurality of tensioning strips 30 are movably arranged in the sleeve 10, and the plurality of tensioning strips 30 are respectively arranged between the rotating shaft 20 and the plurality of through grooves 12; the springs 40 are connected to the inside of the sleeve 10, the springs 40 are also connected to the tensioning strips 30, and the springs 40 are used for driving the tensioning strips 30 to move to be kept in abutting contact with the rotating shaft 20; when the tension bar 30 abuts against the flat surface 21, the tension bar 30 is housed in the sleeve 10; when the tensioning strip 30 abuts the cambered surface 22, the tensioning strip 30 extends out of the sleeve 10 through the through groove 12.

In the initial state, the plane 21 on the peripheral side of the rotating shaft 20 is abutted with the tension bar 30, and the tension bar 30 is in a state of being stored in the sleeve 10; after the label is sleeved outside the sleeve 10, the rotating shaft 20 is rotated to enable the rotating shaft 20 to be abutted to the tensioning strip 30 through the arc surface 22, so that the tensioning strip 30 is pushed out of the sleeve 10, the label is opened through the tensioning strip 30, the assembly of the label is firm, and the problem that the existing unwinding mechanism cannot prevent the label from sliding and loosening is practically solved.

As shown in fig. 1 and 2, a handwheel 50 is connected to the rotating shaft 20, and the handwheel 50 is disposed outside the sleeve 10.

When the hand wheel 50 is rotated, the rotation of the rotating shaft 20 can be realized, so that the stretching and retracting of the tension bar 30 can be manually controlled; of course, the motor and the reducer can be used for driving rotation in a matching mode, and selection can be carried out according to actual requirements during production.
