Embodiment 1

[0035] Basic as attached figure 1 Shown: a high-speed printing machine for outer packaging materials, including a support frame, on which a printing roller 1 and a rubber roller 2 are horizontally rotated and connected, wherein the rubber roller 2 is located above the printing roller 1, and the packaging material 3 to be printed It passes between the rubber roller 2 and the printing roller 1, so the printing roller 1 plays the role of printing, and an ink unit located directly above the rubber roller 2 is also provided on the support frame, and the ink unit is used to transfer ink to the rubber roller 2 Then, the rubber roller 2 prints the ink onto the packaging material 3. The transfer technology of the ink unit is the existing conventional technology, which will not be repeated in this embodiment.

[0036] In this implementation, the packaging material 3 moves to the right, so that the printing roller 1 rotates clockwise, while the rubber roller 2 rotates counterclockwise, a...

Embodiment 2

[0039] Basic as attached figure 2 Shown: The difference from Example 1 is that the cross-section of the side of the fixed block 4 close to the rubber roller 2 and the sponge block 5 exposing the adsorption groove is arc-shaped, and the center of the circle is on the same cross-section as the rubber roller 2 The centers of the circles overlap, so that the sponge block 5 and the rubber roller 2 are more fit together, and the adsorption capacity of the ink on the surface of the rubber roller 2 is improved.

Embodiment 3

[0041] The difference from Embodiment 2 is that an end cover is provided at one end of the fixed block 4, and the end cover is detachably connected to the fixed block 4, and a sealing ring is provided between the end cover and the fixed block 4, so that the operator can The sponge block 5 can be replaced more conveniently.

Abstract

The invention relates to the technical field of printing presses, and particularly discloses a high-speed printing press for an outer packing material. A printing roller and a rubber roller are horizontally and rotatably connected with a support frame, and an ink unit is further arranged on the support frame; an adsorption unit positioned on one side, close to the heading direction of the packingmaterial, of the rubber roller is arranged on the support frame; the adsorption unit comprises a fixing block and an adsorption pump, and a cavity is formed in the fixing block; an adsorption groove facing the rubber roller is formed in the side wall of the fixing block, and a sponge block is arranged in the cavity; the sponge block located at the adsorption groove is exposed out of the adsorptiongroove, and is tightly attached to the outer wall of the rubber roller, and adsorption holes communicating with the cavity are formed in the fixing block; and the adsorption holes are connected withthe adsorption pump through pipelines. According to the high-speed printing press, printing ink on the surface of the rubber roller is cleaned in real time, that is, the printing ink on the surface ofthe rubber roller is cleaned by the adsorption unit immediately after transfer printing of the rubber roller is completed, in this way, the retention time of the printing ink on a rubber layer of therubber roller can be shortened; and in addition, according to the scheme, when the rubber roller is cleaned, shutdown is not required, and the production efficiency is guaranteed.

Description

technical field [0001] The invention relates to the technical field of printing machines, in particular to a high-speed printing machine used for outer packaging materials. Background technique [0002] In offset printing, the rotating rollers include printing plate rollers, rubber rollers, bearing rollers, etc., among which the printing plate rollers are in contact with the rubber rollers during the rotation process. The rubber rollers are also called rubber rollers, and their surfaces are covered with rubber layers. The layer has good lipophilic properties, can adhere to ink, transfer or transfer the ink existing on the image surface of the printing plate to the surface of the rubber roller, and transfer the image information to the packaging material when the packaging material passes between the rubber roller and the carrier roller superior. [0003] During the process of transferring the printing plate ink from the printing plate roller to the rubber roller, and then t...
