Roller type hot printing device for packaging printing production line

Abstract

The invention discloses a drum type hot stamping device for a packaging and printing production line, which comprises a base plate, a supporting leg, a shock absorbing device, a first supporting plate, a hot stamping roller, a backing roller, a first rotating shaft, a first slider, and a chute , the second rotating shaft, the second slider, the first rack, the first gear, the third rotating shaft, the first worm gear, the first helical tooth, the fourth rotating shaft, the spring, the second rack, the second gear, The fifth rotating shaft, the second worm gear and the second helical teeth, the present invention is provided with a first support plate, a chute and a second slider, so that when the thickness of the paper tape changes, the backing roller is always tightly attached to the hot stamping roller , to adapt to paper tapes of different thicknesses, with a first helical tooth, a second helical tooth, a first worm gear, a second worm gear, a first gear, a second gear, a first rack, a second rack, a first slide The block and the second slider adjust the distance between the backup roller and the hot stamping roller through the cooperation of the above components to meet different production needs. The operation is simple, convenient and practical.

Description

technical field [0001] The invention relates to a device for a packaging and printing production line, in particular to a drum-type hot stamping device for a packaging and printing production line. Background technique [0002] With the development of society, heat transfer machines have been widely used. At present, people generally install hot stamping pattern blocks on the hot stamping rollers of heat transfer machines, and pad rollers are installed under the hot stamping rollers. Anodized aluminum guide rollers are installed on both sides of the roller, and roll paper guide rollers are installed on both sides of the backing roller. [0003] During hot stamping, the anodized aluminum strip and the reel are guided by the anodized aluminum guide roller and the reel guide roller, and are compressed at the contact point between the hot stamping roller and the backing roller. When pressing, the aluminum layer on the anodized aluminum strip , according to the pattern on the ho...

AI Technical Summary

Problems solved by technology

However, in existing heat transfer machines, the distance between the hot stamping roller and the backing roller is not easy to adjust, and when hot stamping paper of different thicknesses, the distance between the hot stamping roller and the backing roller must be adjusted accordingly, and the overall operation becomes difficult. more troublesome
