in order to avoid the hard product, the hot pressing head 61 and the hot pressing sleeper 48 are damaged in the heat transfer process, the hot pressing head spring 56 is sleeved on the beam connecting rod 52, when the hot pressing head 61 and the hot pressing sleeper 48 are contacted, the outer edge of the joint connecting hole 54 can push the hot pressing head spring 56 to be further compressed along the beam connecting rod 52 to play a role of buffering, so that the hot pressed product can be hot pressed whether the product is hard or soft, particularly the hard product, and the damage caused by the rigid contact of the hot pressing upper plate assembly and the hot pressing sleeper 48 is avoided.

The label tape 1 is output from between the traction outer rubber roller 30 and the compression roller 31, guided by the transition roller, sequentially combined with the feeding guide roller 62, the discharging guide roller 63, the upper sheet tape storage roller 73 and the lower sheet tape storage roller 74, and then output to the tape collecting assembly 5.

When the pressure of the label tape 1 on the feeding guide roller 62 and the discharging guide roller 63 changes to the two roller bodies, particularly when the pressure is increased, the pressure is transmitted to the tape stretching plate 64, the tape stretching spring 70 is compressed between the tape stretching connecting rod 65 and the cross arm by the Zhang Daiban, and the tape stretching connecting rod 65 can be forced to move upwards to slide in a matched mode through the tape stretching sliding rod through hole 69 by the buffer effect of the tape stretching spring 70 by Zhang Daiban, so that the label tape 1 is prevented from being damaged.

When the hot-pressing upper plate assembly moves downwards, a supplementary section is needed to be added on the label tape 1 at the two sides of the hot-pressing upper plate assembly; the upper belt stock roller 73 moves downwards along with Zhang Daiban 64, the lower belt stock roller 74 moves up and down, and the label 1 between the upper belt stock roller 73 and the lower belt stock roller 74 is released and just complemented to the two sides of the hot-pressing upper plate group;

similarly, when the hot-pressing upper plate assembly moves downwards, the label tapes 1 on two sides of the hot-pressing upper plate assembly are released and are supplemented between the upper sheet tape storage roller 73 and the lower sheet tape storage roller 74;

the label tape 1 between the lower tape stock roll 74 and the subsequent transition roll of the traction outer rubber roll 30 can be adjusted by itself, so that the problem of length compensation of the label tape 1 caused by up-and-down movement of the hot-press upper plate group is solved.

In example 4, further optimizing example 3, a transition guide roller 76 is disposed between the label supply assembly 2 and the pull roller assembly 3, between the pull roller assembly 3 and the feed guide roller 62, and between the sheet stock lower roller 74 and the take-up assembly 5, and the transition guide roller 76 is rotatably connected to the seat plate 33.

A measuring mark assembly 77 is arranged between the traction roller assembly 3 and the hot pressing assembly 4. The side mark assembly is a photoelectric sensor and detects continuous labels on the mark belt 1 so as to determine the time node of the pause transmission of the mark belt 1. The photoelectric sensor is a groove type photoelectric sensor.

The hot pressing pillow block 48 is fixed on the base 78, the seat plate 33 is connected with the base 78 through a connecting arm 79, and a laser marking assembly 80 is arranged on the connecting arm 79. The laser reticle assembly 80 is due to the positioning of the product.

The outside of the hot pressing assembly 4 is further provided with a protection plate 81, the protection plate 81 is connected with the beam guide frame 51 through a protection plate connecting rod 82, and the protection plate 81 is vertically arranged, preferably a transparent glass or plastic plate. The protection plate 81 may play a role in protecting the hot press assembly 4.

The foregoing is merely a preferred embodiment of the present invention, and it should be noted that it will be apparent to those skilled in the art that modifications and variations can be made without departing from the technical principles of the present invention, and these modifications and variations should also be regarded as the scope of the invention.
