Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0014] Such as Figure 1 to Figure 4 As shown, the offset printing sleeve with automatic constant temperature control in this embodiment includes an outer cylinder 1 and a threaded inner cylinder 2, the two ends of the threaded inner cylinder 2 and the outer cylinder 1 are respectively sealed and fixed by flanges 3, and further passed Sealing ring 4 seals. The outer cylinder 1 is sheathed on the outer periphery of the threaded inner cylinder 2 to form a continuous spiral flow groove a, and a constant temperature medium is passed into the spiral flow groove a to realize the constant temperature control of the sleeve.

[0015] In order to facilitate the fixing of the printing plate 9 on the outer cylinder, the surface of the outer cylinder 1 is provided with an axially extending slot b, and the two edges of the inner buckle of the printing plat...

Abstract

The invention relates to an automatic constant temperature-controlled offset printing sleeve, comprising an outer cylinder and a threaded inner cylinder, two ends of the threaded inner cylinder and the outer cylinder are sealed and fixed by flanges respectively, and the outer cylinder is sleeved in the thread A continuous spiral flow groove is formed on the outer circumference of the cylinder, and the constant temperature control of the sleeve is realized by introducing a constant temperature medium into the spiral flow groove. The combined offset printing sleeve of the invention has a constant temperature structure, which facilitates the temperature control of the sleeve by using a constant temperature medium, ensures the constant temperature regulation of the offset printing sleeve when transferring ink, thereby improving the ink printing quality.

Description

technical field [0001] The invention belongs to the technical field of offset printing, and in particular relates to a constant temperature offset printing sleeve. Background technique [0002] The replaceable sleeve is a great progress to solve various printing lengths suitable for rotary continuous printing. The key component of the printing machine transfers the ink to the sleeve, and then transfers the sleeve to the printing surface. The temperature caused by low-speed operation Elevation can have a significant impact on ink print quality. For offset printing, the offset printing process requires the temperature of the ink to be constant within a certain range, and the traditional sleeve cannot realize automatic constant temperature control during the ink transfer process. In particular, it becomes an obstacle to the realization of waterless offset printing, so the constant temperature control of the offset printing sleeve is a technical problem that those skilled in th...
