Description

Technical Field

[0001] The utility model relates to the technical field of printing and embossing integrated machines, and specifically relates to a printing and embossing integrated machine. Background Technique

[0002] Water-absorbent kraft paper is a tough and water-resistant packaging paper, which is brownish-yellow in color and has a wide range of uses. It is often used to make paper bags, envelopes, exercise books, record sleeves, files, and sandpaper, etc. The main quality requirements are flexibility, strength, high burst resistance, and the ability to withstand large tensile and compressive forces without breaking. When producing water-absorbent kraft paper, it needs to be printed and embossed to increase its strength and aesthetics.

Once there is a difference, it will cause a deviation in the position of the printed pattern and the concave and convex traces, affecting the product quality. Content of the Utility Model

The lower ends of the support columns 206 are fixedly connected to the upper side of the slider of the linear motor 207, and the slide rail of the linear motor 207 is embedded in one end of the upper surface of the support side plate 101; the pressure roller support structure 3 includes support plates 301, and the number of support plates 301 is two. The support plates 301 are fixedly installed in the middle of the upper surface of the support side plate 101; both ends of the embossing roller 4 are slidably connected to the inner sides of the support plates 301.

[0045] Specifically, the absorbent kraft paper belt is moved from the rear side of the entire device through the bottom of the embossing roller 4, and cooperates with the support frame 1 to perform embossing from top to bottom. Then, with the embossing roller 4 as the steering axis, the absorbent kraft paper belt is moved from the upper side of the embossing roller 4 to the rear side of the entire device, so that the convex surface produced by the embossing is arched and exposed on the front surface of the embossing roller 4, and then the printing structure 2 brushes over the printed convex surface to perform printing. The base strip 201 is controlled by a high-precision linear motor 207 to adjust the distance from the outer surface of the embossing roller 4, so that the printed material directly outputs the printed convex surface without contacting other flat surfaces of the kraft paper. The working sequence of the entire device is optimized and adjusted. The traditional process is changed from printing first and then pressing the convex surface according to the printed pattern to embossing first, and then using the plane difference produced by the embossed convex surface to perform color printing, thereby avoiding the printing and embossing misalignment caused by the difference in the speed of the printing roller and the embossing roller and the difference in the pattern template, thereby improving product quality.
