Description

Technical Field

[0001] The utility model relates to the technical field of UV printing equipment, in particular to an automatic rotating UV printer. Background Art

[0002] A UV printer is a digital printing device that uses ultraviolet curing technology to print UV ink directly on materials and dry it immediately. During the printing process, the UV printer uses a nozzle to spray ink onto the printed material. While spraying the ink, the UV printer immediately irradiates the sprayed ink pigment with ultraviolet light. Since UV light can cause the chemical substances in the ink to quickly polymerize, solidify and harden, this pigment can become dry in an instant. Most general UV printers are flat printing devices, and the printing materials are mostly plates. The actual products may also include some cylinders or irregular bevels. They cannot be well adapted to such products. The equipment has a single function and poor adaptability. In addition, for some products with different surfaces, the thickness of the printed sprayed paint surface is uneven, and the layer difference is too obvious, resulting in poor overall product texture.

DETAILED DESCRIPTION

[0028] See also Figure 1-9 , the utility model provides a technical solution: an automatic rotating UV printer, comprising a printer body 5, a product processing part for placing products is installed in the printer body 5, and a UV printing head 40 for printing products is arranged above the product processing part;

[0029] The printer body 5 is provided with a UV printing head 4, and a plurality of independently controlled UV printing heads 40 are provided at the bottom of the UV printing head 4. The printer body 5 includes a travel mechanism for driving the UV printing head 4 to move horizontally and vertically.

[0030] The product processing part includes a clamping mechanism, a rotating mechanism and a corner mechanism. The rotating mechanism includes a pair of rotatably arranged product clamps 13 for clamping the product from both sides. The rotating mechanism is integrated on one side of the clamping mechanism to drive the product clamps 13 to rotate. The clamping mechanism and the rotating mechanism are integrally mounted on the rotating shaft seat 1. The rotating shaft seat 1 is integrally mounted on the printer body 5 through the corner mechanism. The rotating axis direction of the rotating shaft seat 1 is perpendicular to the rotating axis direction of the product clamps 13.

[0031] During operation, the product is first positioned and clamped by the clamping mechanism. For conventional axially symmetrical products, such as cylinders, the axis of the cylindrical product is aligned with the axis of the product chuck 13. During spraying, the product chuck 13 is driven to rotate by the rotating mechanism, and the product chuck 13 drives the cylindrical product to rotate coaxially. The UV printing head 4 selects multiple groups of UV printing heads 40 within the range according to the product size to spray the product from top to bottom, so that the cylindrical product can be sprayed with uniform thickness. When the product needs to be sprayed at an angle, such as a product with a large slope, the slope is rotated to a horizontal position, so that the paint surface thickness formed by the overall spraying is more uniform and consistent, and there will be no problems of tilted flow of paint or uneven falling of paint due to height difference. At this time, the corner mechanism is required to drive the rotating shaft seat 1 to rotate. After rotating until the spraying surface of the product is horizontal, the UV printing head 40 at a suitable position is selected according to the spraying range for spraying. At this time, it is an overall flat spraying, and the rotating mechanism does not need to be rotated. In addition, for Figure 4 The cylindrical section of the frustum product shown in the figure can be sprayed in a rotating manner. If the frustum section needs to be sprayed accurately, the frustum section can be tilted at a certain angle through the corner mechanism, such as Figure 4 Then the left end can be rotated upward and lifted, at this time the height difference between the end and the UV printing head 40 will not be too large, the spacing of the whole round table surface will be more consistent, not too large, or the inclination angle will be too large, then the left UV printing head 40 is driven to print separately, the paint surface consistency of the whole product will be better;

[0032] Therefore, the product portion of the utility model can perform rotational spraying on axially symmetrical products through the angle mechanism with a rotating mechanism, and can also spray on flat or inclined products. For products with too large an inclined surface, the inclination angle can be adjusted through the angle mechanism. With multiple groups of independently controlled UV print heads 40, point-to-point precise spraying of the area can be achieved, which can be adapted to more types of products and can achieve more accurate and high-quality spraying process effects, greatly improving the applicability, practicality and quality of the UV printer.
