Embodiment 1

[0020] Embodiment 1 of the online embossing method for PVC flooring of the present invention: This embodiment is suitable for the production process of processing PVC flooring by using a smooth front release paper as a carrier and applying a coating method. The method comprises the following steps: Step 1, after the PVC floor molding material is coated on the surface of the release paper, the release paper coated with the PVC floor layer is subjected to various processes until it is foamed in an oven; Step 2, through at least one pair The roller embosses on the back of the PVC floor layer away from the release paper, and the outer circumference of one of each pair of rollers in all pairs of rollers is provided with a raised back embossing corresponding to the embossing that needs to be printed on the back of the PVC floor layer. Step 3, cooling the surface of the release paper coated with PVC flooring; Step 4, peeling the PVC flooring from the front of the release paper; Step 5...

Embodiment 2

[0022] Embodiment 2 of the online embossing method for PVC flooring according to the present invention: this embodiment is suitable for the embossing method that the frontal embossing of PVC flooring is directly printed through the raised frontal embossing on the front side of the release paper. The difference from Example 1 of the online embossing method for PVC floor is that step 4 and step 5 are removed, but the front side of the release paper is processed with protrusions corresponding to the patterns that need to be printed on the front side of the PVC floor layer Front pattern, before step 3, print the front raised pattern on the release paper on the front of the PVC floor.

[0023] In the above-mentioned embodiments, the online embossing method of PVC flooring is suitable for the production method of PVC flooring using release paper as a carrier. In other embodiments, when the production process of PVC flooring does not require release paper as a carrier, but When the P...

Abstract

The invention relates to an online embossing method for PVC floor and a special production device for the online embossing method. A counter roller for embossing the back surface of a PVC floor layeris arranged between a cooling roller for a PVC floor production process and a drying oven; bulged back embossing is arranged at the periphery of the counter roller for embossing the back surface of the PVC floor layer, i.e., waste heat of the drying oven in the PVC floor production process can be utilized for printing embossing on the back surface of the PVC floor layer; and a special embossing machine is not required for performing special heating and embossing on the PVC floor layer, so that online embossing for the PVC floor in a PVC floor production line is realized, energy is saved, operators needed in a PVC floor layer production process are reduced, and production efficiency of the PVC floor layer is improved, and therefore, the problem that embossing processing producing efficiencyfor the PVC floor in the prior art is low is solved.

Description

technical field [0001] The invention relates to the technical field of PVC floor production and processing, in particular to an online embossing method for PVC floor, and also relates to a special production device for the online embossing method. Background technique [0002] At present, there are two ways to print patterns on both sides of PVC floor in the production process of PVC floor. The embossed front side of the PVC floor is embossed to print the pattern on the front of the PVC floor, and the pattern on the back of the PVC floor needs to unwind the finished PVC floor after rolling to a special embossing machine for special heating of the finished PVC floor And embossing, in order to get a PVC floor with patterns printed on both sides of the front and back; in the second way, when the release paper with both sides of the front and back is glossy as the carrier to manufacture the PVC floor, when the finished PVC floor is in the After the production line is completed ...
