Description

Technical Field

[0001] This utility model relates to the field of printing roller processing, and more specifically, to a printing roller drying device. Background Technology

[0002] During the printing process, ink transferred from the printing rollers to the printing material (such as paper, plastic film, etc.) needs to dry as quickly as possible. If the ink does not dry in time, quality problems such as smudging and color fading may occur. For example, in high-speed roll-to-roll printing, if the ink cannot dry quickly after the paper has been printed by the printing rollers, the ink on adjacent sheets will smudge during the subsequent winding process.

[0003] Hot air is usually used to dry printing rollers. However, due to the large amount of ink adhering to the surface of the printing rollers, it is difficult to dry the ink quickly, which leads to the extension of subsequent printing work. Therefore, centrifugal drying can be used. However, the existing centrifugal drying method has a fixed rotation radius, which cannot adapt to the rapid drying of printing rollers with different ink amounts.

[0004] Therefore, we have made improvements to this and proposed a printing roller drying device. Utility Model Content

[0005] The purpose of this invention is to address the problem that existing centrifugal drying methods have a fixed rotation radius and cannot adapt to the rapid drying of printing rollers with different ink volumes.

[0006] In order to achieve the above-mentioned objectives, this utility model provides a printing roller drying device to solve the above problems.

[0007] The present invention is as follows:

[0008] The device includes a fixed disk. The outer surface of the fixed disk has a plurality of sliding grooves arranged in a ring. A first rack is slidably connected to the inner wall of the sliding groove. A first gear meshes with the root of the first rack. A retaining ring is fixedly connected to the end of the first rack away from the first gear. A connecting shaft is fixedly connected to the movable end of the first gear. A second gear is also fixedly connected to the outer surface of the connecting shaft. A second rack meshes with the root of the second gear. A retaining ring is fixedly connected to the end of the second rack away from the second gear. The inner wall of the sliding groove is provided with a slot. The first rack is slidably connected to the inner wall of the slot.

[0009] As a preferred technical solution of this utility model, a rotating shaft is fixedly connected to the end of the connecting shaft away from the first gear, a dual-axis motor is fixedly connected to the end of the rotating shaft away from the connecting shaft, a rotating shaft is fixedly connected to the other output end of the dual-axis motor, and a connecting shaft is fixedly connected to the other end of the rotating shaft.

[0010] As a preferred technical solution of this utility model, there are two fixed disks that are symmetrical about the dual-axis motor, and a sleeve is rotatably connected to the outer surface of the fixed disks. The outer surface of the fixed disks is provided with a number of air holes.

[0011] As a preferred technical solution of this utility model, the heating tank is rotatably connected to the fixed plate away from the dual-axis motor surface, and a centrifugal motor is fixedly connected to the fixed plate away from the dual-axis motor surface. The centrifugal motor passes through the heating tank and is fixedly connected to the fixed plate.

[0012] As a preferred technical solution of this utility model, there are two heating barrels that are symmetrical about the sleeve. Each of the heating barrels is threadedly connected to a threaded rod on the side away from the dual-axis motor. The threaded rod and the fixing ring are located at the same horizontal position.

[0013] As a preferred technical solution of this utility model, a blower is connected to the outer surface of the sleeve, an air supply pipe is connected to the output end of the blower, a heating tank is connected to the other end of the air supply pipe, and a support frame is fixedly connected to the centrifuge away from the surface of the heating tank.

[0014] As a preferred technical solution of this utility model, a plurality of water-absorbing plates are fixedly connected to the inner wall of the gas transmission pipe, and the water-absorbing plates are arranged in a linear array on the inner wall of the gas transmission pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] When adjusting the rotation radius of the printing roller, a dual-axis motor is driven to rotate. The rotation of the dual-axis motor drives the rotating shaft and the connecting shaft to rotate, which in turn drives the first gear and the second gear to rotate.
