The first sliding pair 100 conveys the chassis 500 to the dust-sticking part 600 (the chassis 500 is not continuously conveyed on the first sliding pair 100, the chassis 500 is conveyed on the first sliding pair 100 in batches), the chassis 500 after being cleaned is conveyed to the extrusion removing part 300 by the first sliding pair 100 to remove the old labels to form a label-free chassis; the label-free housing is picked up by the second moving pair 200, and the driving roller 720 of the transferring part 700 can provide power therein to push the label-free housing to move towards the second moving pair 200, so as to be picked up by the second moving pair 200 better. The second moving pair 200 receives the non-labeled housing and then conveys the non-labeled housing to the end of the second moving pair 200, that is, the non-labeled housing is completely arranged on the second moving pair 200, and then reversely conveys the non-labeled housing to the position right below the labeling part 400, and the labeling part 400 attaches a new label to the non-labeled housing to form a new labeled housing; the second sliding pair 200 pushes the new label housing to the extrusion rejecting part 300 and the extrusion rejecting part 300 extrudes and paves the new label; the second moving pair 200 continuously conveys the housing 500 on which the new label is placed to the transfer portion 700, the transfer portion 700 starts to operate, the rotating disc 710 of the transfer portion 700 rotates, the driving roller 720 rotates in a direction perpendicular to the conveying direction of the second moving pair 200, the driving roller 720 rotates, the housing 500 moves toward the slide 740 under the force of the driving roller 720, and slides down from the slide 740 to the outside or to the next process, and then waits for the next housing 500.

The working principle is as follows: the first moving pair 100 conveys the machine shell 500 provided with the old label to the dust adhering part 600, the cleaning roller 630 is supported on the top of the machine shell 500 in the moving process of the machine shell 500, the cleaning roller 630 continuously cleans impurities on the surface of the machine shell 500 in the moving process of the machine shell 500, the cleaning roller 630 is gradually supported to the maximum height by the machine shell 500, the machine shell 500 is conveyed under the action of the first moving pair 100 continuously until the machine shell 500 is not contacted with the cleaning roller 630, and the cleaning roller 630 is reset due to self-weight rotation. The cleaned housing 500 is conveyed to the extrusion removing part 300 by the first sliding pair 100, the lifting cylinder 330 is started, the height of the extrusion removing part 300 is adjusted, the razor arms 322 of the extrusion removing part 300 are arc-shaped, the razor arms 322 are spread by chamfers on two sides of the housing 500, the razor arms 322 press two side walls of the housing 500, the razor arms 322 press the housing 500, the second razor edge 323 presses old labels on two sides of the housing 500, and the old labels on two sides are removed. The first razor blade 311 of the upper press plate 310 above the pressing and rejecting part 300 rejects the old label above the set cover 500.

The second moving pair 200 takes in the non-label housing and reversely conveys the non-label housing to a position below the labeling part 400.

The unwinding roller 410 unwinds, and conveys the label to the peeling roller 430, the label body is attached to the label-free casing, and the label base film bypasses the peeling roller 430 to reach the winding roller 420, and is wound by the winding roller 420. The new chassis with the label attached thereto reaches the press-removing portion 300 by being conveyed by the second transfer pair 200. Since the upper pressing plate 310 of the pressing and rejecting part 300 is an arc-shaped hard plate, the second sliding pair 200 pushes the new casing to move, and when the new casing is in contact with the upper pressing plate 310, the upper pressing plate 310 gradually presses the new label on the new casing to spread the new label. The second moving pair 200 continuously conveys the housing 500 on which the new label is placed to the transfer portion 700, the transfer portion 700 starts to operate, the rotating plate 710 of the transfer portion 700 rotates, the driving roller 720 rotates in a direction perpendicular to the conveying direction of the second moving pair 200, the driving roller 720 rotates, and the housing 500 slides toward the slide 740 by the force of the driving roller 720, and then slides down from the slide 740 to the outside or to the next process.

It should be noted that, in the process of removing the old labels, it is critical to realize the squeezing and removing part 300, that is, the razor arm 322 squeezes the chassis 500, and the second razor blade 323 squeezes the old labels on two sides of the chassis 500, and removes the old labels on two sides; the first razor edge 311 of the upper platen 310 above removes old labels from above the chassis 500.

In the process of attaching the new label, in order to ensure that the new label can be attached neatly, the key point of the process depends on the extrusion removing part 300, namely the upper pressing plate 310 is an arc-shaped hard plate, the second sliding pair 200 pushes the new machine shell to move, and when the new machine shell is in contact with the upper pressing plate 310, the upper pressing plate 310 gradually extrudes the new label on the new machine shell so as to pave the new label;

the razor arm 322 presses against the chassis 500 to ensure straight travel of the chassis 500. Through the dual-purpose form to extrusion rejection portion 300, fine saving rejection and the process time of laminating the label, the intervention of full-automatic equipment has reduced error rate and label waste rate to a certain extent, carries reverse setting, under the same conditions, can occupy less space, and the space occupancy is low, and functional module gathers the ization.
