As shown in FIG. 1, a pure PVC wallpaper printing, embossing and slitting machine suitable for water-based ink includes a feeding mechanism 100, a traction mechanism 200, a corona mechanism 300, which are sequentially arranged along the printing and processing direction of the PVC wallpaper substrate. Tensioning mechanism 400, at least one printing mechanism 500, cooling mechanism 600, embossing preheating mechanism 700, embossing mechanism 800, slitting mechanism 900, winding mechanism 1000, etc.

Among them, the feeding mechanism 100 is covered with a roll of PVC wallpaper base material, which is used as a raw material for printing.

The traction mechanism 200 is composed of three rubber rollers 210 that rotate synchronously and autonomously. The rubber rollers pull the PVC wallpaper substrate set in the feeding mechanism through the frictional force with the surface of the PVC wallpaper substrate and input the PVC wallpaper substrate to the rear mechanism. . In detail, the rotational speed and diameter of the above three rubber rollers are the same, so as to ensure that the PVC wallpaper substrate attached to it will not be stretched and deformed due to different linear speeds.

The tension mechanism 400 is used to detect whether the surface tension of the PVC wallpaper substrate meets the required standards for printing before entering the printing mechanism 500. In detail, the tension mechanism includes a tension detection roller, and the tension detection roller 410 is located in the printing device. At the entrance of the PVC wallpaper base material, there is a tension adjusting device 420 for adjusting the tension of the PVC wallpaper base material through the value detected by the tension detection roller. In detail, the tension adjusting device includes a adjusting roller secured on the PVC wallpaper base material 421 and an adjusting device 422 that can drive the adjusting roller to relax or tighten the PVC wallpaper substrate to adjust its tension. The mechanism that the roller realizes the lifting and lowering.

The corona mechanism 300 performs corona treatment on the surface of the fast-passing PVC wallpaper substrate to enhance the adhesion of the substrate.

As shown in FIG. 1 , the printing mechanism 500 includes: a printing device 510 in which the inlet of the PVC wallpaper substrate and the outlet of the PVC wallpaper substrate of the tension adjustment mechanism are received; The drying device 520 received by the outlet of the wallpaper base material.

In detail, the printing device includes a plate roller 511 and a printing roller 512 arranged up and down; preferably, the printing roller arranged above the plate roller can be adjusted up and down through the rack adjustment device 513 connected to it to adjust the printing plate. The pressure of the roller and the printing roller on the substrate (PVC wallpaper substrate). Under the plate roller, there is an ink fountain 514 for holding water-based ink. The lower part of the plate roller 511 is immersed in the water-based ink in the ink fountain and rotates to achieve inking on the surface. The knife 515 is used to hang the excess ink on the plate roller. Preferably, the squeegee is at an angle of 60° to 45° with the horizontal plane, so as to ensure that the squeegee can scrape off the ink on the plate roller. Reduce the relative wear of the doctor blade and the plate roller, and prolong the service life of both.

The drying device 520 includes an isolation cover 521 arranged above the printing device. The isolation cover is made of metal material and has a temperature insulating layer on its inner wall; the two sides below the isolation cover are respectively provided with an entrance for a PVC wallpaper base material And the outlet of the PVC wallpaper substrate, wherein the inlet of the PVC wallpaper substrate is connected with the outlet of the PVC wallpaper substrate of the printing device. Two pieces of warm air baffles 522 are arranged inside the isolation hood in an "eight" shape. The warm air baffles roughly divide the interior space of the isolation hood into two parts, the trapezoidal drying cavity 521a and the rest. the warm air cavity 521b. Two air inlets are arranged symmetrically on both sides below the warm air cavity, and an air outlet is left at the upper end of the warm air cavity. The PVC wallpaper substrate enters from one of the air inlets, and is guided by the inner guide roller. The forward trajectory is parallel to the warm air baffle. When the PVC wallpaper substrate is printed, the two air supply devices 523 arranged at the air inlet of the drying chamber send the dry warm air in the warm air chamber into the drying chamber, and the water-based ink adhered to the surface of the PVC wallpaper substrate is blown into the drying chamber. Dry treatment. The air outlet of the air supply device 523 is set toward the length direction of the PVC wallpaper substrate to ensure that the drying warm air can move along the surface of the PVC wallpaper substrate. This method can achieve the effect of drying and quickly drying the water in the water-based ink. , and will not produce a large force on the heated PVC wallpaper substrate, thereby minimizing the possibility of the PVC wallpaper substrate being deformed by force. A dehumidification and heating device 524 is installed at the air outlet of the drying chamber 521a. After the air drying treatment, the newly heated air is discharged into the warm air cavity for the use of the air supply device. The device can achieve the effect of recycling warm air and reducing energy consumption. In the drying chamber 521a, an infrared heating device 525 is arranged.

In a specific embodiment, the infrared heating device may be a resistance heating device.

A further improvement of the above-mentioned embodiment is that a number of spoiler grooves 522a facing the surface of the PVC wallpaper substrate are arranged in the length direction of the warm air baffle 522. When passing between the PVC wallpaper base material and the warm air partition in the drying cavity, the warm air in advection state changes into a turbulent flow under the action of the spoiler slot, which greatly increases the size of the warm air. The convection of the air helps the warm air to take away the moisture in the water-based ink.

A further improvement of the above-mentioned embodiment is that each spoiler groove extends along the width direction of the warm air baffle, and its cross section is in the shape of a four-hearted oval curve that is concave upward (that is, concave toward the direction of the warm air cavity). The shape can make the warm air smoothly enter into the spoiler groove 522a, and generate a relatively strong swirling clear flow at the end of the spoiler groove to drive the drying warm air near the warm air baffle in the drying chamber and the belt near the PVC wallpaper substrate. There is sufficient convection between warm air with moisture. In order to maximize the utilization of heating air.

In this embodiment, the cooling mechanism 600 is used to achieve this function. Specifically, the cooling mechanism is composed of two adjacent cooling rollers 610. In a specific embodiment, in order to improve the cooling effect, the cooling rollers achieve rapid cooling of themselves through the cooling water circulating inside.

As shown in Figure 1, after the pattern printed on the surface of the PVC wallpaper substrate is finalized, the next step of embossing can be performed. Before this step, in order to ensure a good embossing effect, the PVC wallpaper substrate can be pre-processed. Heat treatment to make the temperature of the PVC wallpaper substrate close to the temperature required for embossing. And this step is realized 700 by an embossing preheating mechanism, and in specific implementation, the embossing preheating mechanism may be an infrared heating device. When the PVC wallpaper base material passes through the device, it is uniformly heated to the set temperature as a whole, so as to realize the softening effect of the PVC wallpaper base material and facilitate the processing of the embossing mechanism 800 later.

As shown in FIG. 1 , the embossing mechanism 800 includes a pair of embossing rollers 810 distributed up and down for pressing the PVC wallpaper substrate passing through the two. In this embodiment, in order to be able to press various patterns of wallpaper If required, the embossing structure can be multiple.
