Description

Technical Field

[0001] The utility model relates to the field of slitting machines, in particular to a heat transfer film rewinding and slitting machine. Background Art

[0002] The heat transfer decoration process involves transferring the decorative pattern onto the surface of the building material being decorated by heating the heat transfer film once, creating a high-quality decorative film. During the heat transfer process, heat and pressure are used to separate the protective layer and the pattern layer from the polyester substrate. Hot melt adhesive then permanently bonds the decorative layer to the substrate.

[0003] Chinese patent number CN202321340750.4 discloses a film slitting and rewinding machine, which is characterized by comprising a frame, wherein a feed roller, a rewinding roller, a slitting assembly, a pre-tensioning roller and a winding roller are installed inside the frame along the film feeding direction. The rewinding roller comprises a first rewinding roller and a second rewinding roller, and the spacing between the first rewinding roller and the second rewinding roller is adjustable. The slitting assembly is installed above the film through a first rotating shaft, and the first rotating shaft is rotatably installed inside the frame. A rotating motor is provided outside the frame and fixedly connected to the first rotating shaft. The slitting assembly comprises two groups of slitting seats, the middle part of the two groups of slitting seats is slidably installed in the middle part of the first rotating shaft, and two groups of slitting discs are symmetrically installed at both ends of the slitting seat, and the slitting discs are in contact with the top of the film. A transmission pulley is fixedly installed at one end of the winding roller, and a transmission motor is installed at the bottom of the frame. The output end of the transmission motor is connected to the transmission pulley through a transmission belt. A film pressing plate is elastically attached to one side below the winding roller.

[0004] From the above, it can be seen that the slitting of standard-sized films is achieved through the slitting assembly and the slitting roller, and the slitting is smoother. At the same time, the slitting size can be adjusted by adjusting the cylinder. Two groups of slitting discs are provided on the same slitting seat. The slitting discs on the other side can be quickly replaced and maintained by rotating the motor, and alternating work can avoid overheating. However, this case still has the following shortcomings: when slitting the rewound thermal transfer film, it is often necessary to make corresponding adjustments to the slitting distance position. The existing technology requires braking the entire body during adjustment, and then adjusting the slitting position, which results in low production efficiency during slitting.

[0005] Therefore, a thermal transfer film rewinding and slitting machine is proposed to solve the above problems. Utility Model Content
