Description

Technical Field

[0001] The invention relates to a device for roller-forming a plastic floor, in particular to a device for adjusting the pattern when there is an error in the roller-forming. Background Art

[0002] The current trend of plastic flooring product development is to use plastic materials to replace natural wood and reduce the damage to natural materials. One type of plastic flooring has a 3D embossed pattern on the surface, which is very popular among consumers. Fig.10 As shown, a background technology is patent application number CN201620778488.5, which is a previous design of the inventor of the present invention. The previous case is to set a pair of pattern systems in a rolling device for rolling a substrate 81, a printing layer 82 and a wear-resistant layer 83 into one. The pair of pattern systems includes an electronic control unit (not shown in the figure), and a film feeding roller 91 electrically connected to the electronic control unit, a tension sensor 92, a first CCD sensor 93, a laser sensor 94, and an encoder 95. The tension sensor 92 is arranged on the film feeding roller 91 to sense the tension of the printing layer 82 during transportation. The first CCD sensor 93 is arranged at an appropriate position at the starting point of the printing layer transportation to detect the color mark and node information of the printing layer. The laser sensor 94 is arranged on the outside of the pattern roller 96 to detect the origin mark information of the pattern roller. The encoder 95 is arranged on the rotating shaft of the pattern roller 96 to detect the speed information of the pattern roller. When the plastic floor is roll-formed, the values ​​sensed by the first CCD sensor 93 and the laser sensor 94 are transmitted to the electronic control unit to determine whether the color mark or node of the printing layer 82 is synchronized with the origin of the pattern roller 96. If not, the rotation speed of the pattern roller 96 can be adjusted, or the tension of the printing layer 82 can be adjusted by the film feeding roller 91, so that the conveying speed of the printing layer 82 is synchronized with the rotation of the pattern roller 96, so that when the substrate, the printing layer and the wear-resistant layer are pressed together, the pattern or texture 821 of the printing layer accurately corresponds to the concave and convex embossing on the embossing roller 96, presenting a three-dimensional pattern structure (such as Fig.11 ).

[0003] However, if Fig.12 If the printed layer is offset in angle during the conveying process, the pattern lines 821 will be misaligned with the concave and convex embossing 961 of the embossing roller 96 and cannot be accurately aligned, which will result in defective products. When this misalignment occurs, the above-mentioned alignment system cannot be corrected and the entire printed layer can only be readjusted, causing inconvenience in production operations and needs to be improved.

DETAILED DESCRIPTION

[0027] See also Figure 1 As shown in FIG. 9 , the pattern adjustment device of the plastic floor of the present invention comprises a substrate 11 for forming the plastic floor, a printed layer 12 with a pattern and a transparent wear-resistant layer 13, a rolling device 20 and an adjustment unit 60, wherein:

[0028] The rolling device 20 includes a calender 30 , and a printing layer winder 21 and a wear-resistant layer winder 22 for conveying the printing layer 12 and the wear-resistant layer 13 to the calender 30 .

[0029] The calender is an existing machine, which can be a vertical four-roller structure, or a horizontal four-roller, a horizontal five-roller, or a horizontal six-roller structure. This case uses a horizontal five-roller calender 30 as an illustrative embodiment. Its structure is to set a certain thickness roller 32, a pre-lamination roller 33, an embossing roller 34, and a pressing roller 35 on a frame 31, and set a heater 39 at an upper position on the outer side of the pre-lamination roller 33. The main reason is that the outer surface of the embossing roller 34 is formed with a concave-convex embossing 341 that is the same as the pattern of the printing layer 12. During molding, the substrate 11, the printing layer 12, and the wear-resistant layer 13 are respectively transported to the pre-lamination roller 33 to overlap and pre-lamination. After being heated by the heater 39, the embossing roller 34 and the pressing roller 35 are used to cooperate with each other to roll and form a plastic floor with three-dimensional embossing.

[0030] The main feature of the present invention is that when the embossing roller 34 and the pressing roller 35 are assembled on the frame 31, one end of either of them is set as a fixed end 36 and the other end is a movable end 37, and the adjustment unit 60 is arranged at the outer side corresponding to the movable end 37. The selection of the movable end 37 is determined by the combination and arrangement of the embossing roller 34 and the pressing roller 35.

[0031] First, Figure 1As shown, when the embossing roller 34 and the laminating roller 35 are arranged horizontally relative to each other, one end of the embossing roller 34 is locked on the frame 31 to become the fixed end 36, and the other end is assembled on an independent frame plate 71 to become the movable end 37. The independent frame plate 71 of the movable end 37 is arranged on a cross plate 38, and the cross plate 38 is further arranged on the frame 31, and the adjustment unit 60 is arranged below the frame 31 corresponding to the movable end 37.

[0032] Furthermore, if Figure 3 As shown, when the embossing roller 34 and the pressing roller 35 are arranged vertically opposite to each other, one end of the pressing roller 35 is a fixed end 36 locked to the frame, and the other end is assembled on an independent frame plate 71 to become a movable end 37. The independent frame plate 71 of the movable end 37 is arranged on a cross plate 38'. At the same time, a slide rail 311 is provided below the frame 31 corresponding to the cross plate 38', so that the other end of the cross plate 38' can be embedded and assembled on the slide rail 311; and the adjustment unit 60 is arranged on the outer side of the frame 31 corresponding to the movable end 37.

[0033] The adjustment unit 60 is arranged at the outer side or the lower side of the movable end 37, and one end is linked with the movable end 37 to drive the movable end 37 to make a fine adjustment displacement. The adjustment unit 60 comprises at least a power source 61 and a telescopic rod 62 arranged at one end of the power source 61. The telescopic rod 62 can be driven by the power source 61 to apply a displacement force to the movable end 37. The power source 61 can be manually controlled or electrically controlled. The detailed implementation structure is described below:

[0034] First, if Figure 1 , Figure 2 When the adjustment unit 60 is disposed below the movable end 37 of the embossing roller 34 , two power sources 61 may be provided. A telescopic rod 62 at one end of each power source 61 is passed through the frame 31 and then linked with the cross plate 38 .

[0035] If the power source 61 of this embodiment is manually controlled, each power source 61 is provided with a gear box with a gear transmission mechanism inside, and a linkage handle 64 is provided on the outside of one of the power sources 61, and a linkage rod 63 is used on the outside of the opposite end to be connected with another power source 61' for transmission, and a clutch element 65 is provided on the linkage rod 63, so that the two ends of the linkage rod 63 can be used in a connected or separated manner. When the clutch element 65 is connected, the two power sources 61 and 61' can be driven to operate at the same time by the rotation of the linkage handle 64, so as to drive the movable end 37 to be raised and lowered horizontally; and if the clutch element 65 is separated, the rotation of the linkage handle 64 can only drive one power source 61 to operate alone, so as to drive the movable end 37 to be raised and lowered at a tilt angle on one side.

[0036] Based on the above, Figure 4If the adjustment unit 60 is electrically controlled, each power source 61 can be a servo motor and electrically connected to a controller 66. The controller 66 can control the operation of the power source 61 through electronic signals to drive the movable end 37 to move.

[0037] Furthermore, if Figure 3 , Figure 5 When the adjustment unit 60 is disposed outside the movable end 37 of the laminating roller 35, a single power source 61 can be provided, and the extension and retraction rod 62 at one end of the power source 61 is connected to the outside of the independent frame plate 71. When the power source 61 drives the telescopic rod 62 to move, the movable end 37 can be adjusted along the slide rail 311. The power source 61 of this embodiment can be manually controlled. The power source 61 is a gear box, and a linkage handle 64' is protruding on one side. When the linkage handle 64' rotates, it can drive the gear mechanism inside the power source 61 to operate, so that the telescopic rod 62 can be extended and retracted.

[0038] In this way, by utilizing the mechanism design of the movable end 37 and the adjustment unit 60, when the embossing roller 34 cooperates with the laminating roller 35 to roll-form the substrate 11, the printing layer 12 and the wear-resistant layer 13 into one body, if the position of one side of the printing layer 12 is offset and the texture of its pattern cannot be accurately aligned with the concave-convex embossing 341, the movable end 37 can be driven to move by the adjustment unit 60 to adjust the texture of the pattern to be accurately aligned with the concave-convex embossing 341.

[0039] Based on the above, Figure 5 When the position of the printing layer 12 is offset, the offset side will be at the movable end 37. Because when the production operation is first calibrated, the printing layer 12 is positioned at the fixed end 36 side, and the movable end 37 side is used for adjustment. Therefore, if the position at the movable end 37 side is offset and the pattern pattern and the concave-convex embossing 341 are misaligned, the movable end 37 can be driven by the adjustment unit 60 to move in the direction of the concave-convex embossing 341, so that the pattern pattern and the concave-convex embossing 341 are parallel and overlapped, so as to achieve the purpose of pattern adjustment. In addition, if Figures 6 to 9A , Fig. 9B When the plastic floor production equipment with three-dimensional embossing includes a pair of flower systems 40 , the adjustment unit 60 can be electrically connected to the electric control unit 50 that controls the pair of flower systems 40 .

[0040] The alignment system 40 at least includes a first sensor 41, a second sensor 42, a tension regulator 43, and a third sensor 44, wherein:

[0041] The first sensor 41 can be an electric eye or a camera, and is disposed at the starting point of the conveying path of the printing layer 12. Figure 7The printing layer 12 corresponds to the outer side of the first sensor 41, and a plurality of positioning origins 121 are arranged at equal intervals according to a predetermined length. The length between each positioning origin 121 and other adjacent positioning origins 121' is based on the circumference of the embossing roller 34 to form a printing unit 122. In practical application, the circumference of the embossing roller 34 is preferably slightly larger than the length of the printing unit 122. The first sensor 41 is used to transmit the information of each positioning origin 121 detected on the printing layer 12 to the electronic control unit 50.

[0042] The second sensor 42 is used to sense the angle and position of the embossing roller 34 during rotation. The embossing roller 34 is provided with at least one starting point 342 at an appropriate position. The second sensor 42 is used to transmit information of each detection of the starting point 342 to the electronic control unit 50 .

[0043] Secondly, the starting point 342 can be set at an appropriate position on an outer side surface of the embossing roller 34. The starting point 342 can be a signal receiving element, and the second sensor 42 can emit a light signal. When the embossing roller 34 rotates, the light signal emitted by the second sensor 42 contacts the starting point 342 and transmits the sensed signal to the electronic control unit 50.

[0044] The tension regulator 43 is disposed at an appropriate position outside the starting end of the printing layer 12 for adjusting the tension of the printing layer 12 during transportation.

[0045] The third sensor 44 can be arranged on the outer side where the printing layer 12 is rolled and formed by the embossing roller 34 and the laminating roller 35, or on the conveying path of the finished product after rolling, to sense whether the positioning origin 121 on both sides of the printing layer 12 is on a horizontal straight line, or has an angular offset, and transmit the signal to the electronic control unit 50.

[0046] The electronic control unit 50 is electrically connected to the roller pressing device 20, the calender 30, the alignment system 40 and the adjustment unit 60. It has a computing module 51. When receiving the sensing signal of each positioning origin 121 of the printing layer 12, the computing module 51 divides each printing unit 122 into a certain number of equal divisions. Figure 8 , and according to the travel distance and conveying speed of the printing layer 12 from the conveying starting point to the embossing roller 34, a simulation state of its continuous conveying is constructed.

[0047] like Fig. 9A , Fig. 9BWhen the electronic control unit 50 receives the signal of the starting origin 342 of the embossing roller 34, the operation module 51 is used to simulate the average division of the circumference of the embossing roller 34 into a number of numbers, and the number is the same as the number of simulated divisions of the printing unit 122, and then the simulated data of the printing layer 12 is compared with the simulated data of the embossing roller 34 to determine whether the embossing 34 is accurately opposite to the pattern of the printing layer 12 when the embossing roller 34 rolls the substrate 11, the printing layer 12 and the wear-resistant layer 13. If the speed of the printing layer 12 is too fast or too slow, the tension of the printing layer 12 can be adjusted by the tension regulator 43 to adjust the error between the embossing 341 of the embossing roller 34 and the pattern of the printing layer 12. Secondly, if the electronic control unit 50 receives a signal that a deviation occurs on one side of the printing layer 12, the deviation value can be calculated by the angle of the deviation, and then the adjustment unit 60 is controlled to drive the movable end 37 to correct the deviation value so that the pattern texture is accurately opposite to the concave and convex embossing 341.

[0048] The above description is only illustrative rather than restrictive of the present invention. Those skilled in the art will understand that many modifications, changes or equivalents may be made without departing from the spirit and scope defined by the claims, but all will fall within the scope of protection of the present invention.
