The technical field is as follows:

the invention relates to the field of floors, in particular to a synchronous pattern aligning system for new-generation plastic floors.

Background art:

the plastic floor is made of plastic materials to replace natural wood, damage to natural data is reduced, the plastic floor is a trend of development of plastic floor products, patterns on the surface of the plastic floor have a three-dimensional effect of relief, and the plastic floor is popular with consumers. An improved synchronous registration system for plastic floor disclosed in chinese patent No. cn201711387170.x, which is the prior creation of the applicant of the present invention, is to arrange a first sensor at the outer side of the conveying path of the printing layer, a plurality of positioning origins are arranged at equal intervals on the side of the printing layer corresponding to the first sensor according to a predetermined length distance, the length between each positioning origin and other adjacent positioning origins is based on the circumferential length of the embossing roller to form a printing unit, and the first sensor is used to transmit the information of each positioning origin detected by the printing layer to an electric control unit. The second sensor is used to detect the position of the embossing roller when rotating, the circumferential length of the diameter of the embossing roller is approximately equal to the printing unit length of the printing layer, and a starting origin is arranged on the embossing roller, and the second sensor is used to transmit the information of each detection of the starting origin to the electric control unit. When the electric control unit receives each positioning origin signal of the printing layer, the operation module is used to perform average division and continuous transmission simulation of a plurality of numbers on each printing unit; and when receiving the initial origin signal of the embossing roller, simulating the circumferential length of the embossing roller by using the operation module to divide a plurality of numbers evenly, wherein the number of the numbers is the same as the number of the simulated divisions of the printing unit, and comparing the simulation data of the printing layer with the simulation data of the embossing roller to judge whether the embossing of the embossing roller is accurately opposite to the patterns of the printing layer when the substrate, the printing layer and the wear-resistant layer are rolled and molded by the embossing roller, if the printing layer speed is too fast or too slow, the tension of the printing layer can be adjusted by the tension adjuster to adjust the error between the embossing of the embossing roller and the patterns of the printing layer.

The positioning original point of the printing layer is formed on the outer side of the printing pattern in the technology, so that the setting procedure of the positioning original point is increased in the production operation of the printing layer, meanwhile, the required volume is relatively large in the printing process of the printing film, and the production cost and the waste of materials are increased. In addition, the length between two adjacent positioning origins of the printing layer is used as a reference for setting the technical printing unit, the length reference is exactly equal to the circumference length according to the diameter of the embossing roller, however, because the pattern on the printing layer and the positioning origins generate errors of position and size more or less during printing operation, when the pattern aligning system utilizes the positioning origins of the printing layer and the initial origins of the embossing roller to perform analog comparison, the judgment accuracy is distorted due to the size errors between different positioning origins. Furthermore, the original location point of the printing layer is arranged outside the pattern, the original point of the embossing roller is arranged on the outer side surface of the rotating shaft, the two original points are not arranged on the pattern, when the operation module is used for simulation, only the cutting graph lines which are divided by simulation can be used for comparison, the position of the error between the pattern on the printing layer and the three-dimensional embossing on the embossing roller cannot be accurately known, and the efficiency and the quality of force error adjustment can be influenced.

Secondly, chinese patent application No. CN201811540433.0 discloses the following technical content, as shown in fig. 9, a first camera 5 is provided above a patterned roller 10 of a rolling device for photographing embossings on the outer surface of the patterned roller 10, a second camera 6 is provided above a grid roller 21 for photographing patterns on a PVC color film 1 passing through the grid roller 21, an encoder 9 is provided on a spindle head of the patterned roller 10, when the patterned roller 10 rotates, a microprocessor 13 starts the encoder 9, and a pulse signal output by the encoder 9 is sent to the microprocessor and converted into a speed signal to control the speed of a sheet feeder 7, so that the speed of the sheet feeder is synchronized with the speed of the patterned roller 10; and triggering camera shooting by using the Hall sensor 18 according to the setting, thereby capturing an embossing pattern of the pattern roller 10 and a pattern of the PVC color film 1 on the grid roller, obtaining an online detection result through an image processing unit and comparing the online detection result with the image shot by the two cameras, then correspondingly adjusting the unreeling machine 2 and the unreeling machine 7 through two image deviation structures, and further arranging the movable platform 3 and the tension detection roller 4 adjacent to the unreeling machine 2.

The technical scheme utilizes the mode that images shot by a first camera 5 and a second camera 6 are synchronously compared to judge whether the images deviate or not, because the shot images are the whole patterns, and a checkered roller 10 is adjacent to a grid roller 21, when the images shot by the two cameras are transmitted to an image processing unit for interpretation, and then the interpreted information is transmitted to a control end for outputting an adjusting signal, the PVC color film 1 is rolled and molded by the checkered roller 10 and the grid roller 21 at a common production speed, and the PVC color film is not suitable for a common or quick production line and only suitable for products with a slower production line.

Moreover, the images shot by the first camera 5 and the second camera 6 are respectively an embossed pattern on the surface of the checkered roller 10 and a PVC color film 1 pattern on the grid roller 21, because the checkered roller 10 and the grid roller 21 are both of a circular roller structure, the images shot by the first camera 5 and the second camera 6 are both plane images of the circular roller, no matter the embossed pattern on the surface of the checkered roller 10 or the PVC color film 1 pattern on the grid roller 21, a distortion phenomenon occurs when an original three-dimensional circular arc surface is shot into a plane, and when the two images are compared and read for a deviation value under the condition, the deviation accuracy is also out of alignment. Furthermore, the patterned roller 10 is made of metal, and the surface of the plastic floor is dirty and atomized when the plastic floor is formed by rolling, so that the plastic floor needs to be cleaned and maintained regularly, and if the embossing of the patterned roller 10 is dirty and atomized, the definition of the image of the embossing pattern shot by the first camera 5 is also affected adversely, and the misalignment condition of comparison and judgment of the deviation value is caused, so that the improvement is needed.

Similarly, when receiving the data transmitted by the second sensor 52, the second starting point 448 is determined by calculation analysis or electric eye sensing, and the identification module 56 equally divides the three-dimensional pattern into equal parts with the second starting point 448 as the origin and assigns coordinate values.

The electronic control unit 60 is electrically connected to the first apparatus 41, the second apparatus 42, the third apparatus 43, the calender 44, and the registration system 50.

When the adjustment is performed, the tension adjuster 422 adjusts the tension of the printing layer so that the unit pattern 321 is equally spaced apart from the embossing roller 443 by equally spaced apart circumferential lengths, thereby achieving the registration adjustment. The pattern lines of the unit graph are accurately aligned with the three-dimensional engraved patterns of the embossing roller, so that the aligning quality and the production efficiency of the plastic floor are improved.
