Description

Technical Field

[0001] The utility model relates to the field of printers, in particular to a suction printing upper heat insulation air supply device. Background Art

[0002] A film transfer printer is a device used to transfer patterns or images on a film to various materials (such as mobile phone cases, keyboard keycaps, clothes, etc.). It is widely used in fields such as personalized customization and industrial production.

[0003] When using a film transfer printer, the film to be transferred and the target material are placed on the transfer printer, and the parameters of the transfer printer, such as temperature, pressure, and time, are adjusted. Then the transfer printer starts to heat, so that the pattern or image on the film softens and tightly combines with the transfer adhesive layer. While heating, a certain pressure is applied by the transfer printer to transfer the pattern or image on the film to the target material. After the transfer is completed, the target material is cooled to make the pattern or image more firmly adhere to the material. Currently, when the transfer printer heats, it usually installs heating tubes above the printing substrate, and the heat generated by the heating tubes is used to heat the film. However, the problem is that the heat generated by the heating tubes is mainly concentrated in the surrounding area of the heating tubes, resulting in high energy consumption, and uneven heating of different positions of the film, affecting the heating transfer quality, which needs to be improved.

[0023] Example 1, see the attached drawings of the specification Figure 1 , 3 -5, a suction printing upper part heat insulation air supply device, including an outer cover 01 and an inner cover 02 with a certain taper. The inner cover is highly connected to the lower port of the outer cover 01. A mirror reflection plate 21 is connected to the lower port of the inner cover 02. A plurality of heating tubes 22 are arranged side by side on the bottom surface of the mirror reflection plate. The spacing between these heating tubes 22 is the same. A vertical plate is provided at the lower port of the inner cover 02. The inner side surface of this vertical plate is an auxiliary mirror panel 27. The auxiliary mirror panel and the mirror reflection plate 21 are butt-jointed up and down. Mirrored surfaces are formed on the top and side of the heating tubes 22. The heat is reflected downward to the surface of the film through mirror reflection, avoiding heat concentration in the heating tube area and improving the heat utilization rate and heating uniformity.

[0024] An L-shaped flange 25 is provided at the edge of the lower port of the inner cover 02. A hanging ear plate 26 corresponding to the inner side surface of the inner cover is provided at this L-shaped flange. The L-shaped flange is used to improve the anti-deformation strength of the inner cover 02. A support 13 is fixedly connected to the inner side surface of the inner cover. The hanging ear plate 26 is connected to the inner side surface of the support. And a cross brace plate 131 is provided at the bottom surface of the support. This cross brace plate supports the port surface of the inner cover 02. The cross brace plate 131 can play a role in assisting the support of the inner cover 02 and improving its stability when installed in the outer cover 01.

[0025] The outer cover 01 includes an outer shell 141 and an inner shell 142 that are connected to each other. A gap is provided between the outer shell and the inner shell 142 to form a heat insulation cavity. This design enables the outer cover 01 to have a heat preservation and insulation effect.
