When the label is used, when a product is placed on the hot-pressing pillow block 48, the label 1 is also conveyed to a preset position, at the moment, the driving end of the beam driving cylinder 49 moves downwards, the beam 47, the connecting plate 58 and the hot-pressing upper plate assembly (the heat insulation plate 59, the hot-pressing head cover 60 and the hot-pressing head 61) are driven to move downwards, the hot-pressing head 61 is matched with the hot-pressing pillow block 48 to press the label 1 and the product tightly, the label on the label 1 is separated from the label 1 under the action of heat and is transferred onto the product, the heat transfer process is completed, the driving end of the beam driving cylinder 49 moves upwards to drive the hot-pressing upper plate assembly to move upwards to return to the original state, and the;

in the process that the cross beam 47 moves up and down, the cross beam guide rod 50 and the cross beam guide frame 51 play a role in guiding, and the running precision is improved;

In order to avoid the damage to the hot pressing head 61 and the hot pressing pillow block 48 in the thermal transfer process, the hot pressing head spring 56 is sleeved on the cross beam connecting rod 52, and when the hot pressing head 61 contacts with the hot pressing pillow block 48, the outer edge of the joint connecting hole 54 can push the hot pressing head spring 56 to further compress along the cross beam connecting rod 52 to play a role in buffering, so that products with hot pressing can be hot pressed no matter the products are hard or soft, particularly hard products, and the rigid contact between the hot pressing upper plate assembly and the hot pressing pillow block 48 is avoided, and the damage is caused.

The label tape 1 is output from the position between the traction outer rubber covered roller 30 and the compression roller 31, guided by the transition roller, and then sequentially output to the tape collecting component 5 together with the feeding guide roller 62, the discharging guide roller 63, the tape-opening material-storing upper roller 73 and the tape-opening material-storing lower roller 74.

When the pressure of the label tape 1 on the feeding guide roller 62 and the discharging guide roller 63 on the two roller bodies changes, especially when the pressure increases, the pressure is transmitted to the tape tension plate 64, the tape tension plate 64 compresses the tape tension spring 70 between the tape tension connecting rod 65 and the cross arm, and the tape tension plate 64 can force the tape tension connecting rod 65 to move upwards to slide in cooperation with the tape tension sliding rod through hole 69 under the buffer action of the tape tension spring 70, so that the label tape 1 is prevented from being damaged.

when the hot-pressing upper plate assembly moves downwards, a supplementary section needs to be added to the label tape 1 on the two sides of the hot-pressing upper plate assembly; the upper band-opening material storage roller 73 moves downwards along with the band-opening plate 64, the lower band-opening material storage roller 74 moves up and down, and the label band 1 between the upper band-opening material storage roller 73 and the lower band-opening material storage roller 74 is released and just supplemented 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 supplemented between the upper strip storage roller 73 and the lower strip storage roller 74;

the label tape 1 between the lower tension tape storage roller 74 and the subsequent transition roller of the traction outer rubber roller 30 can be automatically adjusted, so that the problem of length compensation of the label tape 1 caused by up-and-down movement of the hot-pressing upper plate set is solved.

Embodiment 4, further optimizing embodiment 3, transition guide rollers 76 are arranged between the label supplying assembly 2 and the drawing roller assembly 3, between the drawing roller assembly 3 and the feeding guide roller 62, and between the tension belt storing lower roller 74 and the belt collecting assembly 5, and the transition guide rollers 76 are rotatably connected on the seat plate 33.

and a measuring and marking assembly 77 is arranged between the traction roller assembly 3 and the hot-pressing assembly 4. The side mark component is a photoelectric sensor and detects continuous labels on the label tape 1 so as to determine the time node of the label tape 1 for suspending transmission. The photoelectric sensor is a groove type photoelectric sensor.

The hot-pressing pillow block 48 is fixed on a 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 marking assembly 80 is due to the positioning of the product.

The outer side 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 and is preferably made of transparent glass or plastic plates. The protection plate 81 can protect the hot press assembly 4 to a certain extent.

the foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
