Taper thermal transfer printing machine

Abstract

The invention provides a taper thermal transfer printing machine capable of thermally printing on a conical surface, and belongs to the technical field of thermal transfer printing. The problem that the thermal transfer printing is unlikely to be conducted for a tapered product in the existing market can be effectively solved by the invention. The taper thermal transfer printing machine comprises a base, wherein a base plate is arranged on the base and is connected with a membrane frame corner plate; an arc rack is arranged on the membrane frame corner plate; a vertical shifting plate is connected to the upper surface of the membrane frame corner plate in a sliding form by two linear guiding rails; a winding membrane guiding frame and an unwinding membrane guiding frame are respectively fixed on both sides of the vertical moving plate; a printing substrate circumference measuring device is arranged on the winding membrane guiding frame; a flower-membrane smoothing roller is arranged on the unwinding membrane guiding frame; a vertical post is arranged on the base plate; a multi-direction tool is arranged on the vertical post; and a lifting thermal-printing roller is arranged on the multi-direction tool. With the adoption of the taper thermal transfer printing machine, a pattern can be transfer-printed on a tapered printing substrate accurately and perfectly, without deformations and wrinkle, so that the product quality is stable; in addition, the taper thermal transfer printing machine is safe and reliable, and is low in cost and high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of heat transfer printing, in particular to a taper heat transfer machine capable of hot stamping on a conical surface. Background technique [0002] A new printing process of thermal transfer printing has been introduced from abroad for more than ten years. The printing process is divided into two parts: transfer film and transfer processing. Transfer film printing adopts dot printing, and the pattern is pre-printed on the surface of the film. The printed pattern is rich in layers, bright in color, ever-changing, with small color difference and good practicability. It can achieve the effect required by the designer and is suitable for mass production. The transfer printing process uses a taper heat transfer machine to transfer the exquisite pattern on the transfer film to the surface of the product. The principle of thermal transfer printing is to pre-print the color pattern on the heat-resistant substrate...

AI Technical Summary

Problems solved by technology

[0003] The traditional thermal transfer machine has obvious advantages in transferring cylindrical products, but for the transfer of conical workpieces, due to the difference in the circumferential speed of the conical substrate and the linear speed of the thermal transfer film during hot stamping, in The linear speed of the two objects is different during the processing, and the transfer carrier is PET film, which is easily stretched when heated, resulting in deformation and wrinkling of the hot stamping pattern. If the product with a large taper is transferred

The pattern of the PET transfer film can only be manually operated, so that the quality of the product cannot be guaranteed, and the operator also has potential safety hazards that may be burned
