Embodiment 1

[0042] This embodiment is a thermal transfer production line for a circular surface of a rotary body, such as figure 1 As shown, including the following settings along the moving direction of the production line: manual inspection of cup quality or automatic inspection, cup positioning station, paper loading station, cup wrapping station, baking station, depaper station and finished product unloading station, There are transfer facilities between each station. The rotating body conveyor belt 3 upper and other compartments are provided with a rotating body circular surface positioning facility 4 . A plurality of transfer paper positioning facilities 2 corresponding to the circular surface positioning facilities 4 outside the rotating body are arranged on the transfer paper conveyor belt 1 . Next to the transfer paper conveyor belt 1, at least one elastic fastening leather feeding device 7, at least one transfer paper feeding device 8, at least one transfer paper clamping devic...

Embodiment 2

[0064] This embodiment is an improvement of the first embodiment, and is a refinement of the first embodiment about the elastic fastening skin. The elastic fastening skin 701 of the present embodiment is a rubber skin 701-2 with a straight strut 701-1 at both ends, as Figure 4 shown.

[0065] The straight strut 701-1 needs to have certain strength and bending resistance, and 304 stainless steel can be used. The rubber skin 701-2 should have greater elasticity and high temperature aging resistance, and the pattern on the transfer paper will not be able to penetrate the skin due to high temperature.

Embodiment 3

[0067] This embodiment is an improvement of the above embodiment, and is a refinement of the U-shaped buckle 702 in the above embodiment. The U-shaped buckle of this embodiment includes a section of plate bent into a U-shaped buckle body, and the side of the U-shaped opening is provided with gaps for clamping two straight struts, such as Figure 5 shown.

[0068] The U-shaped buckle 702 in this embodiment is punched and bent from a section of metal plate customized according to the diameter of the cup body, and the cross-sectional shape in the cross-section perpendicular to the moving direction of the conveyor belt is U-shaped. The side shape is a gap in the middle, with protrusions on both sides, forming two hooks 702-1. There is a circular arc-shaped transition section 702-2 at the junction of the bottom of the gap and the hooks to accommodate the straight support rod 701-1, so that the two protrusions will Straight struts are constrained at the bottom of the notch.

Abstract

The invention relates to a heat transfer printing production line and an automatic heat transfer printing method for external circular surfaces of rotary bodies. The heat transfer printing productionline comprises a paper loading station, a cup wrapping station, a baking station and a paper dismantling station, the paper loading station comprises a rotary body conveying belt and a transfer printing paper conveying belt which are parallel and operating synchronously, positioning facilities, transfer printing paper positioning facilities, elastic fastening rubber feeding devices, transfer printing paper feeding devices, transfer printing paper wrapping-clamping devices, buckle feeding devices, rotary body end face positioning and pushing facilities, a finished product conveying belt, buckledemounting devices and a finished product discharging device are included, and rotary body transfer printing assemblies comprise elastic fastening rubber and U-shaped buckles. All the devices for assembling, baking and demounting the rotary body transfer printing assemblies are arranged together through the conveying belts, so that continuous and automatic production of the rotary bodies is realized. The elastic fastening rubber enables transfer printing paper to be closely attached to the rotary bodies, so that transfer printing images are clearer and more beautiful. The U-shaped buckles with the small size make mounting and demounting more convenient, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a thermal transfer production line and an automatic thermal transfer printing method for the circular surface of a rotary body. Pattern processing production line. Background technique [0002] Thermal transfer printing is to first print the selected pattern on a piece of transfer paper through the printer, and then paste the transfer paper on the surface of the item to be transferred (such as: porcelain, stainless steel, etc.), and the transfer paper will be pasted. The items on the printed paper are placed in a high-temperature environment of about 200 degrees Celsius for a few minutes, and the special ink on the thermal transfer paper sublimates immediately and adheres to the surface of the resin-coated item that is close to it, completing a selected image from The thermal transfer process of transfer paper to the surface of the article. The image after thermal transfer is bright in color, and the pattern and the surface o...
