Description

Technical Field

[0001] The present application relates to the field of printed matter, and in particular to a pressing structure for printed matter. Background Art

[0002] Printed matter refers to printed books, newspapers, pictures, etc. It is various products of printing and is the general term for various finished products produced by printing technology. It is mostly printed by a printing press. When a conventional printing press is used, the printed matter to be processed is placed on the upper end of the printing press body. After connecting the body to the power supply, the adjusting frame on the body surface moves and then the printing mechanism is used to process the printed matter.

[0003] Regarding the above related technologies, the inventor believes that when placing printed matter, since the materials of some printed matter are relatively thin, light and soft, the edges are prone to bending and warping during the printing process, resulting in deviations in the printing of the printing press and affecting the finished product effect of the printed matter.

[0004] The above information disclosed in this background art is only used to increase the understanding of the background art of the present application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Utility Model Content

A printing mechanism is fixedly connected to the top of the adjusting frame. A slider is slidably installed on the inner wall of the support frame. The size specifications of the surface of the slider are adapted to the size specifications of the inner wall of the support frame. One end of the two sliders close to each other is fixedly connected with a limiting frame. The size specifications of the bottom end of the limiting frame are adapted to the size specifications of the top of the body. There are two adjusting frames, and the two adjusting frames are symmetrically distributed with the body as the axis of symmetry. One side of the support frame is clamped with the surface of the body, and the bottom end of the limiting frame is slidably connected with the top of the body.

[0008] Preferably, a connecting frame is fixedly installed at the bottom end of the support frame. Two rollers are rotatably connected to the inner wall of the connecting frame. A slide rail adapted to the rollers is provided on one side of the body. The inner wall of the slide rail is slidably installed with the surface of the rollers. A bolt is threadedly connected to the inner wall of the support frame, and one end of the bolt is clamped with the surface of the body.

[0009] Preferably, a spring is fixedly connected to the top of the slider, the top of the spring is fixedly installed on the inner wall of the support frame, and the center of the spring is on the same straight line as the center of the slider.

[0010] Preferably, a chute is provided inside the limit frame, and two limit blocks are slidably connected to the inner wall of the chute. The size specifications of the surface of the limit block are adapted to the size specifications of the inner wall of the chute.

[0011] Preferably, a number of auxiliary wheels are rotatably installed on the inner wall of the limit block. The number of auxiliary wheels is divided into two groups. The two groups of auxiliary wheels are symmetrically distributed with the limit block as the axis of symmetry, and the auxiliary wheels are rubber wheels.

[0012] In summary, the present application includes the following beneficial technical effects:
