DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5A labeling machine capable of accurately labeling includes a labeling device 1, a conveyor belt 2 and a support frame 3, wherein the labeling device 1 and the conveyor belt 2 are both existing technology products, and the specific structure and working principle can be referred to the existing technology disclosure, and the support frame 3 can ensure that the mounting block 4 is stable in the middle position of the conveyor belt 2.

[0023] A mounting block 4 is provided on the support frame 3, and a transmission cavity 10 and an annular cavity 13 are provided inside the mounting block 4. A driving motor 11 is provided in the transmission cavity 10, and a screw 14 extending into the transmission cavity 10 is rotatably provided in the annular cavity 13. The screw 14 is connected to the driving motor 11 through a rotating mechanism, and a movable frame 5 extending to the outside of the mounting block 4 is threadedly installed on the screw 14, and an extrusion groove 16 is provided on the outer wall of the movable frame 5. A positioning rod 9 is provided in the extrusion groove 16 through an extrusion mechanism, and an adjusting wheel 7 is provided above the conveyor belt 2 through a connecting frame 6. The mounting block 4 is circular in design, and a plurality of movable frames 5 are distributed at equal intervals circumferentially relative to the mounting block 4, and a slot matching the movable frame 5 is provided on the connecting frame 6.

[0024] The rotating mechanism includes a driving gear 12 arranged in the transmission chamber 10 and connected to the output shaft of the driving motor 11. A transmission gear 15 is installed on the screw 14. The driving gear 12 is meshed with the transmission gear 15. As shown in the figure, the driving gear 12 and the transmission gear 15 are both bevel gears. With the help of the driving gear 12 and the transmission gear 15, the power transmission of the driving motor 11 is finally realized, and finally the multiple screws 14 are driven to rotate synchronously.

[0025] The extrusion mechanism includes a spring installed in the extrusion groove 16, and both ends of the spring are elastically connected to the outer wall of the positioning rod 9 and the inner wall of the extrusion groove 16 respectively. A positioning hole 8 is provided on the connecting frame 6, and the positioning hole 8 is connected to the slot and corresponds to the positioning rod 9. The spring realizes the extrusion and pushing operation of the positioning rod 9, and can push the positioning rod 9 into the positioning hole 8 to ensure the stability of the movable frame 5 in the slot in the connecting frame 6.

[0026] An annular protective sleeve is provided on the adjusting wheel 7. The annular protective sleeve is made of rubber material. The rubber annular protective sleeve prevents the adjusting wheel 7 from causing contact damage to the outer wall of the product to be labeled, thereby playing a protective role.

[0027] When the utility model is used, when the packaging bottle follows the conveyor belt 2 and moves to the bottom of the sleeve labeling device 1, the driving motor 11 is started, the driving motor 11 drives the driving gear 12 to rotate, the transmission gear 15 drives the transmission gear 15 meshing therewith to rotate, the transmission gear 15 drives the screw 14 to rotate, when the screw 14 rotates, the movable frame 5 will move and cooperate with the connecting frame 6 to drive the adjusting wheel 7 to move, multiple adjusting wheels 7 move close to and finally position the packaging bottle to the center position, not only to adjust its position, but also to ensure the stability of its position after adjustment, in the state of its accurate and stable position, with the sleeve labeling device 1, accurate sleeve labeling processing can be realized, after the sleeve labeling processing is completed, the driving motor 11 is reversed to move the adjusting wheel 7 away from the packaging bottle.

[0028] In this solution, the positioning rod 9 in the positioning hole 8 is pressed, the positioning rod 9 squeezes the spring and disengages from the positioning hole 8 and enters the extrusion groove 16, and then the connection between the connecting frame 6 and the movable frame 5 is released, so that the disassembly of the adjustment wheel 7 and other components is realized, and the annular protective cover installed thereon can be cleaned, maintained or replaced.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
