Preferably, the drying device is also included;

the drying device is arranged at a position opposite to the supporting roller and used for drying the printed matters wound on the supporting roller.

Preferably, the drying device is a fluorescent lamp.

Preferably, the device further comprises a cooling device;

the cooling device is arranged between the supporting roller and the driving device and is used for cooling the printed products passing through the position of the supporting roller and dried by the drying device.

Preferably, the cooling device comprises a cylindrical barrel, the printed products passing through the supporting roller position and dried by the drying device can bypass the barrel, and the printing surface of the printed products is attached to the surface of the barrel;

the cooling device is characterized in that a cooling cavity is arranged in the cylinder, a liquid inlet channel and a liquid outlet channel which can enable the cooling cavity to be communicated with the outside are arranged on the end side of the cylinder, an external refrigerant can enter the cooling cavity through the liquid inlet channel, and the refrigerant entering the cooling cavity is discharged out of the cylinder through the liquid outlet channel after exchanging heat with a printed matter attached to the surface of the cylinder.

The utility model discloses a printing machine, through adopting drive arrangement follows pull out in the colour group the printed matter can wind up on the support is rolled, and the laminating is in support rolling on the surface to the technical scheme of drive arrangement motion can reduce the unsettled length of printed matter on the operation route, prevents that the turned edge from appearing in the printed matter and the folding or the adhesion that leads to.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the following will explain the mobile working chair of the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in fig. 1, a printing press includes: a drive device 1, a color group 2 and a support roller 3. The drive device 1 can continuously pull out the printed matter 4 printed by the color set 2 from the color set 2, the support roller 3 is arranged between the drive device 1 and the color set 2, and the printed matter 4 pulled out of the color set 2 by the drive device 1 can be wound on the support roller 3 and attached to the surface of the support roller 3 to move towards the drive device 1. It should be noted that the supporting roller 3 may be rotatably connected to the frame of the printing machine during installation, so that the supporting roller 3 can rotate under the friction action of the printed matter 4. In this way, the supporting roller 3 can support the printed matter 4 between the driving device 1 and the color set 2, reduce the suspended length of the printed matter 4, and prevent the printed matter 4 from being folded or adhered due to edge curling. Specifically, the color group 2 has a printing roller 21, and the axis of the supporting roller 3 is parallel to the axis of the printing roller 21 and the distance is less than 1 meter, so as to shorten the hanging length of the printed matter 4 as much as possible. Preferably, the printed product 4 has opposite printed sides (not shown) and a back side (not shown) which is conformed to the back roll 3.

As an implementation, as shown in fig. 1, a drying device 5 is further included. The drying device 5 is disposed at a position opposite to the supporting roller 3 to dry the printed matter 4 wound on the supporting roller 3, the drying being performed to dry the ink marks printed on the printed matter 4. In actual manufacturing, the drying device 5 may be a fluorescent lamp, but is not limited thereto, and may be other devices such as a heating wire, etc. capable of achieving the purpose of the invention.
