Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in FIG. 1, the thermal transfer device for improving L OGO adhesion force comprises a frame 1, and a stamping mechanism 2, a pressure-bearing mechanism 3, a feeding mechanism 4 and a winding mechanism 5 which are arranged on the frame, wherein a color roll 6 for thermal transfer passes through the stamping mechanism and the pressure-bearing mechanism which are arranged up and down, and moves forwards under the action of the feeding mechanism and the winding mechanism, the pressure-bearing mechanism 3 comprises a pressure-bearing roller 31, a heating part 32 and a lifting part 33, the pressure-bearing roller is positioned right below the stamping mechanism 2 and is used for bearing a carrier needing thermal transfer, the heating part 32 is used for heating the lower surface of the color tape so as to uniformly heat the upper surface of the color tape, and the lifting part is respectively connected with the pressure-bearing roller and the heating part so as to drive the pressure-bearing roller and the heating part to alternatively lift.

Specifically, the heating unit 32 includes a rod 321 that is disposed obliquely, and an upper end of the rod is inclined toward a lower end surface of the imprinting unit. A heating terminal 322 is arranged on the upper end surface of the rod body, and a slide block 333 is arranged on the side surface of the rod body facing the rack, the slide block is of a T-shaped structure, and is arranged in a T-shaped chute 11 arranged on the rack in a sliding fit manner. Preferably, the inclination angle of the T-shaped sliding groove is the same as that of the rod body.

In addition, the lifting part 33 has a specific structure comprising a lifting cylinder 331 fixedly mounted on the frame, a connecting frame 332 having a U-shaped structure is fixedly connected to an end of an expansion link of the lifting cylinder 331, one of straight arms of the connecting frame is fixedly connected to the lower surface of the pressure-bearing roller 31 to realize the synchronous operation of the pressure-bearing roller and the lifting cylinder, and the other straight arm of the connecting frame is in contact with a roller 333 rotatably mounted on the frame 1. Meanwhile, the rim of the roller 333 is also in contact with the lower surface of the rod 321. It should be noted that the vertical surface of the connecting frame contacting with the roller is the side facing the heating portion, so that when the connecting frame rises, the roller rotates clockwise to drive the heating portion to slide downwards, and when the connecting frame falls, the roller rotates anticlockwise to drive the heating portion to slide upwards, thereby realizing the up-and-down movement of the heating portion and the pressure-bearing roller in a staggered manner. Interference of the heating portion with the carrier at the time of thermal transfer printing is avoided.

As a further improvement of the above embodiment, in order to improve the stability of the transmission, a plurality of transmission teeth 334 are uniformly distributed on the rim of the roller 333 in the circumferential direction. Meanwhile, a plurality of transmission teeth which are linearly distributed are also arranged on the vertical surface of the connecting frame 332 contacted with the roller and the lower surface of the rod body 321 contacted with the roller.

The working principle is that when the embossing is needed, the heating part works, the lifting part is arranged in the descending device, the heating part is close to the lower surface of the color ribbon to heat the lower surface of the color ribbon, after the heating is carried out for a set time, the lifting cylinder acts, the pressure bearing roller is driven by the lifting cylinder to ascend, meanwhile, the heating part is inclined and descends under the conversion of rolling off, space is reserved for a carrier on the pressure bearing roller, the embossing mechanism synchronously and downwards corresponds to the upper surface of the color ribbon to heat rapidly in the second process, and then the pattern on the color ribbon is embossed on the carrier.
