Description

Technical Field

[0001] This utility model relates to the field of sublimation transfer paper testing technology, and particularly to sublimation transfer paper testing equipment. Background Technology

[0002] Sublimation transfer paper is a special type of paper used to transfer images onto various materials using heat transfer technology. During the processing of sublimation transfer paper, some defects may appear on the surface of the transfer paper, which can easily affect the quality standard of the transfer paper product. Therefore, it is necessary to inspect the surface of the transfer paper, and thus a sublimation transfer paper inspection device is used.

[0003] To address this, patent CN209342627U discloses a device for detecting defects in sublimation transfer paper, belonging to the field of sublimation transfer paper technology. It includes a printer, a bottom beam, and a light source assembly. The bottom beam is installed below the printer, and the light source assembly is installed on the bottom beam. The light source assembly includes LED bulbs and ultraviolet bulbs, both of which are mounted on the bottom beam. This invention features a light source assembly on the bottom beam, comprising LED bulbs and ultraviolet bulbs. During printing, the operator can select different light sources according to the purpose of observation. The LED bulbs illuminate the paper surface, facilitating the operator's observation of defects such as white spots, small holes in the original paper, and scratches after printing. The ultraviolet bulbs are suitable for observing the uniformity of the coating on the white paper before printing, thereby avoiding uneven paper coating, reducing human error, and improving product quality.

[0004] While the aforementioned sublimation transfer paper defect detection device avoids uneven paper coating and reduces human error, thus improving product quality, its inconvenience in flattening the paper and eliminating wrinkles and curls makes it difficult to improve detection accuracy, resulting in low applicability.

[0018] The advantages of the thermal sublimation transfer paper testing equipment provided by this utility model are as follows:

[0019] By incorporating a flattening structure, the transfer paper at the top of the conveyor belt is flattened under the action of the pressure roller, thereby eliminating wrinkles and curls in the transfer paper and ensuring a smooth surface. This improves detection accuracy. The sliding rod enhances the stability of the fixed frame during movement. The moved fixed frame drives the pressure roller to move up and down, thus changing the distance between the pressure roller and the conveyor belt. This allows for the flattening of transfer papers of different thicknesses, achieving the function of preventing wrinkles and improving the applicability of the sublimation transfer paper detection equipment.

[0020] By incorporating a guide structure, the stability of the guide plate during movement is enhanced under the action of the movable rod. The moved guide plate will drive the guide column to move.
