Description

Technical Field

[0001] This utility model belongs to the field of printing roller technology, and more specifically, it relates to a PET color film printing roller that is easy to replace. Background Technology

[0002] With the continuous development of technology, PET colored film is being used more and more widely in various fields. PET colored film has good transparency, gloss, and chemical corrosion resistance, and is widely used in packaging, printing, decoration and other industries. In the production process of PET colored film, printing with printing rollers is an important step. It can give PET colored film various patterns and colors, improving its aesthetics and added value. Based on the existing technology, it has been found that the existing printing rollers have some shortcomings. First, the existing printing rollers are not convenient to remove from the equipment. When replacing the outer roller with a pattern, the mounting shaft needs to be removed from the equipment before the outer roller can be disassembled and replaced, which is a relatively cumbersome replacement method. Second, when replacing the outer roller with a pattern, it is not possible to adapt to outer rollers of different lengths. Therefore, only the same type of outer roller can be installed, resulting in poor compatibility. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model relates to a PET color film printing roller that is easy to replace, thereby solving some shortcomings of existing printing rollers. First, existing printing rollers are inconvenient to remove from the equipment. When replacing the patterned outer roller, the mounting shaft needs to be removed from the equipment before the outer roller can be disassembled and replaced, which is a cumbersome replacement method. Second, when replacing the patterned outer roller, it cannot accommodate outer rollers of different lengths. Therefore, only the same model of outer roller can be installed, resulting in poor compatibility.

[0004] The first aspect of this disclosure provides a replaceable PET color film printing roller, achieved by the following specific technical means:

[0005] A replaceable PET film printing roller, comprising:

[0006] The mounting mechanism includes a mounting shaft and a movable rod. The mounting shaft has a circular plate-shaped structure on its exterior.

[0013] 1. This device includes an installation mechanism and a connection mechanism. The installation shaft and the connection shaft are respectively installed on the equipment. A movable rod is movably installed on the installation shaft, and a printing roller is installed on the movable rod. A movable block with a docking block is slidably installed on the connection shaft. The movable tube is sleeved onto the end of the movable tube, and the docking block is inserted into the docking groove. When the printing roller needs to be replaced, the movable tube is pulled to disengage the docking block from the docking groove. At this time, the movable rod can be lifted upward, and the collar on one side can be removed first. Then the printing roller can be removed and replaced. This effectively improves the replacement efficiency of the printing roller, and the printing roller can be replaced without removing the structure that mounts the printing roller from the equipment.

[0014] 2. This device includes an installation mechanism and an external connection mechanism. Circular positioning holes are equidistantly spaced on the movable rod. Collars are inserted at both ends of the printing roller, and the printing roller, along with the collars, is fitted onto the movable rod. Bolts on the collars are inserted into the positioning holes to limit the movement of the printing roller. By equidistantly spaced positioning holes on the movable rod, and fixing the collars to different positions, printing rollers of different lengths can be limited on the movable rod. This allows the device to adapt to printing rollers of different lengths, thereby increasing the adaptability of the printing roller installation. Attached Figure Description
