Description

Printing machine with protection device

Technical Field

The utility model relates to a printing machine technical field especially relates to a printing machine with protection device.

Background

Modern printing presses typically consist of mechanisms for plating, inking, stamping, feeding (including folding), etc. The principle is that the characters or images to be printed are made into printing plate, then it is mounted on the printing machine, then the ink is coated on the position of the printing plate with characters and images by manual or printing machine, then it is directly or indirectly transferred onto paper or other printing material. When printing on paper, the paper is moved to print, but because the paper can shift when moving, the paper is protected by the protection device to prevent the shift of the paper, but the existing protection device can only protect the paper with fixed specification to prevent the shift.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the prior art only can protect the paper of fixed specification to prevent the effect shortcoming of skew, and the printing machine with the protection device.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the printing machine with the protection device comprises a printing machine, wherein connecting grooves are formed in two sides of the printing machine, moving blocks are connected in the connecting grooves through limiting mechanisms, limiting plates are fixedly connected to the upper ends of the moving blocks, threaded rods are fixedly connected between the two moving blocks, the thread directions of the two threaded rods are opposite, and thread sleeves are in threaded connection with the opposite inner sides of the two threaded rods;

the limiting mechanism comprises a fixing seat fixedly connected with the printing machine, a limiting rod is fixedly connected to the fixing seat, a limiting hole is formed in the moving block, and the limiting rod can be inserted into the limiting hole.

Preferably, the threaded sleeve is fixedly connected with a handle sleeve.

Preferably, both ends of the limiting rod are fixedly connected with limiting discs, and the diameter of each limiting disc is larger than the inner diameter of each limiting hole.

Preferably, the periphery of the lower end of the printing machine is fixedly connected with connecting seats, the connecting seats are in threaded connection with threaded columns, and the lower ends of the threaded columns are fixedly connected with supporting seats.

Preferably, the supporting seat is in a shape of a circular truncated cone.

The utility model provides a pair of printing machine with protection device, beneficial effect lies in: through the design that adopts threaded rod, thread bush, limiting plate, movable block to adjust the distance between two limiting plates, so that carry out spacing protection to the paper of different width, prevent the condition of skew.
