Detailed Description

The invention will be further described with reference to the following description and embodiments in conjunction with the accompanying drawings:

example 1

As shown in fig. 1, a label conveying device comprises a power mechanism 1, a feeding mechanism 2, a material stroking mechanism 3 and a frame 4, wherein the feeding mechanism 2 is provided with a conveying platform, a label tape 5 is positioned on the conveying platform and drives the lower label tape 5 to advance, and the power mechanism is arranged at the side part of the frame 4 and used for providing power for the feeding mechanism; the material smoothing mechanism is arranged above the conveying platform and used for smoothing the label belt. The label belt 5 moves forwards under the driving of the feeding mechanism 2 on the conveying platform, and the material stroking mechanism ensures that the label does not wrinkle in the moving process and keeps flat.

As shown in fig. 2-3, the feeding mechanism includes an elastic table 21, an upper roller 22, a lower roller 23 and a jacking cylinder 25, the elastic table 21 forms a conveying platform, a positioning magnet 24 is disposed on the elastic table 21, the positioning magnet 24 is attracted to the surface of the elastic table 21 by magnetic force, and the positioning magnet 24 defines a fixed position of the label tape 5 to keep the label tape 5 from deviating during moving. The upper roller 22 is located on one side of the elastic workbench 21 and is installed on the frame 4, the lower roller 23 is opposite to the upper roller 22, the lower roller 23 is installed on the side edge of the elastic workbench 21, the jacking cylinder 25 is arranged on the lower portion of the elastic workbench 21, the jacking cylinder 25 jacks up the elastic workbench 21, and then drives the lower roller 23 to ascend, so that the lower roller 23 abuts against the upper roller 22 and keeps a certain pressure to adapt to labels with different thicknesses. In the movement, the label tape 5 advances by the friction of the upper and lower rollers, and the positioning magnet 24 defines the position of the label tape 5 not to be deviated.

As shown in fig. 4, the power mechanism includes a motor 11, a synchronizing wheel 12 and a synchronous belt 13, the synchronizing wheel 12 is respectively installed on the motor 11 and the upper roller 22, the synchronous belt 13 connects the two, the motor 11 rotates to drive the upper roller 22 to rotate, and the synchronizing wheel 12 and the synchronous belt 13 are connected through a tooth profile, so that tooth skipping and sliding are avoided in the movement process, and the conveying precision is ensured.
