Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other in any manner without conflict.

[0096] Since the board needs to be cut before the board is pasted with the decorative material, in the related art, the edge of the decorative material is flush with the cut surface of the board, which causes a gap between adjacent decorative plates after the decorative plate is installed, and the edge of a single decorative plate has a burr, which not only affects the decoration effect, but also easily causes the edge of the decorative material to separate and tear. Although the decorative plate material that covers the decoration surface and the cut surface of the board has appeared at present, the decoration quality of the cut surface of the decorative plate material is difficult to guarantee, and adverse effects such as bulging and wear of the decorative material easily occur, which seriously affects the product quality and service life.

[0097] To solve the above technical problems, the present embodiment provides a decorative plate production system, which comprises a control center, a conveying roller, and a plate cutting unit, a paint spraying unit, a cladding unit, and a film pasting unit arranged in sequence along the conveying direction of the conveying roller, wherein the conveying roller, the plate cutting unit, the paint spraying unit, the cladding unit, and the film pasting unit are signal connected with the control center; the conveying roller is used to convey the board to be decorated and the board in the process of decoration or after decoration placed at a predetermined interval at a predetermined speed; the plate cutting unit is used to cut the board to be decorated into a predetermined size; the paint spraying unit is used to spray paint on the cut surface of the board; the cladding unit is used to paste the decorative material on the decoration surface and the cut surface of the board; and the film pasting unit is used to paste a protective film on the surface of the board after decoration. The decorative plate and the production system thereof in the present embodiment realize online cutting, online spraying, online pasting, and online film pasting of the board. The online spraying process can guarantee the quality of the cut surface of the board, avoid quality problems of the cut surface of the board, and cause the decorative material to bulge and wear, guarantee the product quality and decoration effect, and the online pasting process can paste the decorative material on the decoration surface and the cut surface of the board, and further improve the decoration effect.

[0098] The decorative plate and the production system and production process thereof according to the present embodiment will be described in detail below with reference to the drawings. The following embodiments and implementation manners can be combined with each other without conflict.

[0099] Figure 1-1 、 Figure 1-2 and Figure 1-3This diagram shows a top view of a specific embodiment of the decorative panel production system of this invention. (Refer to...)

[0101] The sheet material cutting unit 60 is used to cut the sheet material 100 to be decorated into predetermined sizes to meet the different specifications of the sheet material 100 required by customers. The cutting unit 60 can cut multiple stacked sheet materials 100 at the same time to improve cutting efficiency.

[0102] The painting unit 2 is used to paint the cut surface of the board 100 to cover and protect the cut surface of the board 100, so that the cut surface of the board 100 has a smooth effect. When the decorative material 200 covers the cut surface, it avoids adverse effects such as bulging and wear of the decorative material 200, and ensures the decoration quality and service life.

[0103] The covering unit 3 is used to release the finishing material 200, apply an adhesive to the bonding surface of the finishing material 200, and press the finishing material 200 onto the decorative surface and cut surface of the board 100. The cut surface is generally located on the side of the board 100. The shape of the board 100 is not limited. When the board 100 is a cube, the decorative surface is located on the top or bottom surface of the board 100, and the cut surface is located on the four sides adjacent to the decorative surface. The covering unit 3 applies the finishing material 200 to the decorative surface and the four sides.

[0104] The film application unit 80 is used to apply a protective film 83 to the surface of the decorated panel 100 to protect the decorative surface. The film application unit 80 can apply the protective film 83 to the entire surface of the panel 100, or it can apply the protective film 83 only to the surface of the panel 100 on which the decorative material 200 is applied.

[0105] The decorative panel production system of this embodiment can spray paint the cut surface of the panel 100 online for protection, and automatically cover the decorative surface and cut surface of the panel for decoration, thereby ensuring product quality and decorative effect and improving product service life.

[0106] It should be noted that the decorative material 200 used in the present scheme includes but is not limited to PVC / PP type decorative film, and can also be wallpaper, wall cloth and other soft decorative materials for indoor wall decoration of civil buildings.

[0116] With reference to Figure 1-3 , a turning roller way 10 is arranged between the output end of the third roller way 13 and the input end of the fourth roller way, and the plate 100 on the third roller way 13 can be transferred to the third roller way 13 through the turning roller way 10. The input end of the fourth roller way 14 is located close to the output end of the turning roller way 10, and an unqualified product unloading storage lifting platform 15 is also arranged at this position. The plate 100 with unqualified decorative material 200 enters the unqualified product unloading storage lifting platform 15 through the turning roller way 10. The plate 100 with qualified decorative material 200 enters the fourth roller way 14, so that the plate 100 with qualified decorative material 200 can be coated with the film by the film coating unit 80.

[0117] Because customers have different size requirements for the plate 100, the plate 100 needs to be cut to the size required by the customer before being decorated.

[0118] Figure 2 A structural schematic diagram of an exemplary embodiment of the plate quantity cutting unit 60 is shown. Referring to Figure 2 As shown, the plate quantity cutting unit 60 includes a cutting device and a waste processing device, wherein the cutting device includes a longitudinal saw cutting mechanism 61 for longitudinal cutting of the plate 100 and a cross saw cutting mechanism 62 for cross cutting of the plate 100. The waste processing device includes a longitudinal saw waste processing mechanism 63 for processing of waste generated in the longitudinal cutting process and a cross saw waste processing mechanism 64 for processing of waste generated in the cross cutting process. The plate quantity cutting unit 60 of the present embodiment can simultaneously cut multiple plates 100 to improve cutting efficiency. The longitudinal saw cutting mechanism 61 and the cross saw cutting mechanism 62 can work simultaneously or in sequence, for example, the plate 100 is first longitudinally cut and then cross cut, or the plate 100 is first cross cut and then longitudinally cut.

[0119] In some embodiments, the longitudinal saw cutting mechanism 61 includes a longitudinal conveying table 611, a longitudinal saw cutting table 612, a longitudinal saw positioning and aligning device 613, a longitudinal saw mechanical arm 614, and a longitudinal saw cutting device 615. The longitudinal saw positioning and aligning device 613 is arranged on the longitudinal conveying table 611, the longitudinal saw cutting table 612 is located at the output end of the longitudinal conveying table 611, the longitudinal saw mechanical arm 614 is located at the end of the longitudinal conveying table 611 away from the longitudinal saw cutting table 612, and the longitudinal saw cutting device 615 is located above the longitudinal saw cutting table 612.

[0120] The longitudinal conveying table 611 is used to adjust the plate 100 to a set longitudinal orientation to avoid the situation of inclined longitudinal cutting surface and improve the quality of longitudinal cutting.

[0121] The longitudinal saw positioning and aligning device 613 is used to align the lateral edges of the plate 100 and position the longitudinal cutting position of the plate 100. When cutting multiple stacked plates 100 simultaneously, aligning the lateral edges of the multiple plates 100 can ensure the regularity of the longitudinal cutting of the multiple plates 100.

[0122] The longitudinal saw mechanical arm 614 is used to sequentially push the plate 100 to the longitudinal saw positioning and aligning device 613 and the longitudinal saw cutting table 612 before longitudinal cutting, and push the plate 100 from the longitudinal saw cutting table 612 to the working range of the cross saw cutting mechanism 62 after longitudinal cutting, to realize the movement of the plate 100 between the longitudinal conveying table 611, the longitudinal saw cutting table 612, and the cross saw cutting mechanism 62.

[0123] The longitudinal saw cutting saw is used to cut the plate 100 at least once in the longitudinal direction to make the lateral size of the plate 100 reach a preset lateral size.

[0124] By way of example, referring to Figure 1-1 and Figure 2 The loading machine 71 transports the plate 100 to the first roller 11 located at the entrance of the longitudinal conveying table 611, and the first roller 11 transports the plurality of plates 100 to be cut to the longitudinal conveying table 611. The longitudinal conveying table 611 comprises a longitudinal saw universal roller air floating conveying table, which can adjust the plate 100 to a set longitudinal orientation, for example, adjust the plate 100 to the longitudinal side wall of the plate 100 perpendicular to the longitudinal conveying table 611, and the transverse side parallel to the longitudinal conveying table 611. The transmission of the longitudinal conveying table 611 is realized by the combination of precision gear and rack mechanism. The longitudinal saw positioning alignment device 613 comprises a first alignment baffle 6131 and a plurality of longitudinal positioning sensors 6132 arranged along the length direction of the first alignment baffle 6131, and the first alignment baffle 6131 is perpendicular to the longitudinal conveying table 611 and used for aligning the plurality of plates 100. The first alignment baffle 6131 can be set as a telescopic baffle, and when the plurality of plates 100 need to be aligned, the first alignment baffle 6131 is extended to be higher than the longitudinal conveying table 611 to align the transverse edges of the plurality of plates 100, and when the transverse edges of the plurality of plates 100 are aligned, the first alignment baffle 6131 is retracted to be lower than the longitudinal conveying table 611 to make the plate 100 enter the longitudinal cutting table 612 through the longitudinal conveying table 611. The plurality of longitudinal positioning sensors 6132 are used to position the longitudinal cutting position of the plate 100 to determine the start point of the longitudinal cutting feed amount. The longitudinal saw mechanical hand 614 adopts a scissors type clamping method, when the clamping part loosens the plate 100, the bottom jaw of the clamping part will be lower than the longitudinal conveying table 611, and when the clamping part clamps the plate 100, the bottom jaw will be automatically lifted to be flush with the longitudinal conveying table 611, without damaging the plate 100. The longitudinal saw cutting device 615 comprises a longitudinal saw pressing beam (not shown in the figure) and a longitudinal saw cutting saw (not shown in the figure), and during longitudinal cutting, the longitudinal saw pressing beam is used to press the plate 100 to avoid deviation of the plate 100 during longitudinal cutting, and the longitudinal saw cutting saw is used to cut the plate 100 longitudinally. The longitudinal cutting size is set by special cutting software, and the longitudinal cutting times are not limited. In order to ensure the accuracy of the transverse size of the plate 100, it is preferred to cut longitudinally twice.

[0125] After the board 100 enters the longitudinal saw working area, the longitudinal saw mechanical arm 614 automatically pushes the board 100 to align at the first alignment baffle 6131, and at the same time, the longitudinal positioning sensor 6132 positions the longitudinal cutting position (i.e. the starting point of the longitudinal cutting feed amount) of the board 100. After the longitudinal saw mechanical arm 614 clamps the board 100, it starts to feed according to the set longitudinal cutting size to the longitudinal saw cutting table 612. The longitudinal saw pressure beam automatically descends to press the board 100 tightly, ensuring that the board 100 does not move during the cutting process. The longitudinal saw cutting saw cuts the board 100 according to the set longitudinal cutting size. After the longitudinal saw cutting saw completes the cutting, the feeding machine 71 transports the subsequent board 100 to the first roller 11 located at the entrance of the longitudinal conveying table 611.

[0126] In some embodiments, the cross saw cutting mechanism 62 comprises a cross conveying table 621, a cross saw cutting table 622, a cross saw positioning and alignment device 623, a cross saw mechanical arm 624 and a cross saw cutting device 625; the cross saw positioning and alignment device 623 is arranged on the cross conveying table 621, the cross saw cutting table 622 is located at the output end of the cross conveying table 621, the cross saw mechanical arm 624 is located at the end of the cross conveying table 621 away from the cross saw cutting table 622, and the cross saw cutting device 625 is located above the cross saw cutting table 622.

[0127] The cross conveying table 621 is used to adjust the board 100 to the set cross orientation, avoiding the situation that the cross cutting surface is inclined, and improving the cross cutting quality.

[0128] The cross saw positioning and alignment device 623 is used to align the longitudinal edges of the board 100 and position the cross cutting position of the board 100. When cutting multiple boards 100 at the same time, aligning the longitudinal edges of the multiple boards 100 can ensure the regularity of the cross cutting of the multiple boards 100.

[0129] The cross saw mechanical arm 624 is used to push the board 100 to the cross saw positioning and alignment device 623 and the cross saw cutting table 622 in sequence before cross cutting, and push the board 100 from the cross saw cutting table 622 to the first roller 11 located at the output end of the cross saw cutting table 622 after cross cutting, so as to realize the movement of the board 100 between the cross conveying table 621, the cross saw cutting table 622 and the first roller 11.

[0130] The longitudinal saw cutting device 615 is used to cut the board 100 at least once in the cross direction to make the longitudinal size of the board 100 reach the preset longitudinal size.

[0131] The longitudinal sawing machine 614 pushes the board 100 onto the transverse conveying table 621, which comprises a transverse sawing universal roller air floating conveying table that can adjust the board 100 to a set transverse orientation, for example, adjust the board 100 to a transverse side wall side edge of the board 100 perpendicular to the transverse conveying table 621 and the longitudinal side edge parallel to the transverse conveying table 621. The transmission of the transverse conveying table 621 is realized by a combination of precision gear and rack mechanism. The transverse sawing positioning alignment device 623 comprises a second alignment baffle 6231 and a plurality of transverse positioning sensors 6232 arranged along the length direction of the second alignment baffle 6231, which is perpendicular to the transverse conveying table 621 and used for aligning a plurality of boards 100. The second alignment baffle 6231 can be set as a telescopic baffle, which is extended to be higher than the transverse conveying table 621 when the plurality of boards 100 need to be aligned, so that the longitudinal edges of the plurality of boards 100 are aligned, and then the second alignment baffle 6231 is retracted to be lower than the transverse conveying table 621, so that the board 100 enters the transverse cutting table 622 through the transverse conveying table 621. The plurality of transverse positioning sensors 6232 are used to position the transverse cutting position of the board 100 to determine the start point of the transverse cutting feed amount. The transverse sawing cutting device 625 comprises a transverse sawing pressing beam (not shown in the figure) and a transverse sawing cutting saw (not shown in the figure), which are used to press the board 100 to avoid displacement of the board 100 during transverse cutting and to cut the board 100 transversely. The transverse cutting size is set by a special cutting software, and the transverse cutting times are not limited. In order to ensure the accuracy of the longitudinal size of the board 100, it is preferred to perform two transverse cuttings.

[0132] When the board 100 enters the transverse sawing working area, the transverse sawing machine 624 automatically pushes the board 100 to the second alignment baffle 6231 for alignment, and the transverse positioning sensor 6232 positions the transverse cutting position of the board 100 (i.e. the start point of the transverse cutting feed amount). After the transverse sawing machine 624 clamps the board 100, it starts to feed to the transverse sawing cutting table 622 according to the set transverse cutting size, the transverse sawing pressing beam automatically descends to press the board 100 tightly to ensure that the board 100 does not move during cutting. The transverse sawing cutting saw cuts the board 100 transversely according to the set transverse cutting size. After the transverse sawing cutting saw completes the cutting, the longitudinal sawing machine 614 pushes the subsequent board 100 into the transverse conveying table 621 to start a new round of transverse cutting.

[0133] In some embodiments, the longitudinal saw waste processing mechanism 63 includes a longitudinal saw waste collecting device 631 arranged on one side of the longitudinal saw cutting mechanism 61 for collecting the longitudinal cutting waste and conveying the collected waste to a longitudinal saw waste crushing device 632 for crushing the longitudinal cutting waste. The cross saw waste processing mechanism 64 includes a cross saw waste collecting device 641 arranged on one side of the cross saw cutting mechanism 62 for collecting the cross cutting waste and conveying the collected waste to a cross saw waste crushing device 642 for crushing the cross cutting waste.

[0134] For example, referring to Figure 2 , the longitudinal saw cutting table 612 includes a longitudinal saw waste flipping device (not shown in the figure), the longitudinal saw waste collecting device 631 includes a longitudinal saw waste conveying belt arranged below the longitudinal saw waste flipping device, and the longitudinal saw waste crushing device 632 is arranged at the output end of the longitudinal saw waste conveying belt. The longitudinal saw waste flipping device is used to drop the waste generated by the longitudinal saw cutting onto the longitudinal saw waste conveying belt, and the longitudinal saw waste conveying belt conveys the collected waste to the longitudinal saw waste crushing device 632 for crushing. The cross saw cutting table 622 includes a cross saw waste flipping device (not shown in the figure), the cross saw waste collecting device 641 includes a cross saw waste conveying belt arranged below the cross saw waste flipping device, and the cross saw waste crushing device 642 is arranged at the output end of the cross saw waste conveying belt. The cross saw waste flipping device is used to drop the waste generated by the cross saw cutting onto the cross saw waste conveying belt, and the cross saw waste conveying belt conveys the collected waste to the cross saw waste crushing device 642 for crushing. The crushed longitudinal saw waste and cross saw waste can be recycled.

[0135] The plate cutting unit 60 of the embodiment is controlled by a PLC (programmable logic controller), and the longitudinal cutting and cross cutting are combined into a 90-degree longitudinal and cross saw cutting mode to simultaneously or separately cut the plate 100. During the cutting process, the direction of the plate 100 does not need to be manually rotated, and the plate 100 is automatically positioned to achieve precise cutting of the plate 100 in any size. The cutting edge is free of burrs, the corners are neat, and there is no damage. During the cutting process, dust can be quickly collected, and there is no dust floating in the field. The corners generated during cutting can be collected and crushed online. The plate 100 in the plate cutting unit 60 is automatically fed, longitudinally sawed, cross sawed, and automatically discharged, and the processes work simultaneously without interfering with each other. The processes cooperate with each other to achieve high efficiency of plate 100 cutting.

[0136] Because the cut surface of board 100 after cutting exhibits powdering and flaking, affecting its quality and the bonding quality of the surface material 200, and potentially leading to bulging and wear of the surface material during use, this solution employs a painting unit 2 to cover the cut surface of board 100 with paint, providing protection to prevent these quality issues and extend product lifespan.

[0137] Figures 3-5 A schematic diagram of an exemplary embodiment of the painting unit 2 is shown, with the conveyor roller 1 along... Figure 3 The X-direction transport is shown. (Refer to...) Figures 3-5 As shown, the painting unit 2 includes a painting device 21, a paint storage device 22, and a drying device 23. The painting device 21 includes at least one pair of spray guns 211 located on both sides of the conveyor roller 1, used to spray primer onto the cut surfaces of the sheet material 100 during conveying on the conveyor roller 1 to protect the quality of the cut surfaces of the sheet material 100. The paint storage device 22 is connected to the painting device 21 and is used to store and supply primer to the painting device 21. The drying device 23 is located between the painting device 21 and the coating unit 3, used to dry the painted sheet material 100 and preheat the decorative surface of the sheet material 100 to ensure the quality of subsequent bonding with the decorative material 200. In this embodiment, the painting unit 2 can simultaneously paint the cut surfaces of multiple stacked sheet materials 100 to improve painting efficiency and effect.

[0138] In this embodiment, the painting device 21 includes at least one pair of spray guns 211 and a drive component 212 connected to the spray guns 211. The drive component 212 is used to drive the spray guns 211 to move, and the spray guns 211 are used to spray paint on the cut surfaces of the board 100.

[0139] In one exemplary embodiment, at least one pair of spray guns 211 may be provided only in the width direction of the conveyor roller 1, or at least one pair of spray guns 211 may be provided at predetermined intervals in the conveying direction of the conveyor roller 1. In this embodiment, the spraying directions of each pair of spray guns 211 are arranged opposite to each other.

[0140] In an optional embodiment, the paint spraying unit 2 further comprises a shape detection assembly (not shown in the figure) arranged on the conveying roller 1, which is used to detect the size information of the plate 100 and feed back to the control center. When multiple plates 100 are arranged in a stack and are simultaneously subjected to paint spraying, the shape detection assembly detects the size information of the plates 100 arranged in a stack. According to the feedback result of the shape detection assembly, the control center generates a movement trajectory of the spray gun 211, and controls the driving component 212 to drive the spray gun 211 to move according to the movement trajectory. This scheme realizes automatic adjustment of the paint spraying path when different specifications of plates 100 are subjected to paint spraying, realizes automation of the paint spraying process, and ensures accurate paint spraying on the cutting surface of the plate 100, thereby avoiding the influence of inaccurate spraying position of the spray gun 211 on the paint spraying effect.

[0141] Referring to Figure 3 In the process of conveying the plate 100 into the paint spraying device 21 by the conveying roller 1, the shape detection assembly detects the shape of the plate 100, generates size information of the plate 100, and sends the size information of the plate 100 to the control center in real time. The control center generates a movement trajectory of the spray gun 211 of the paint spraying device 21 according to the received size information of the plate 100, and controls the driving component 212 to drive the spray gun 211 to move according to the movement trajectory. The size information of the plate 100 includes length information (along the X direction shown in Figure 3 , height information (along the Z direction shown in Figure 3 , and width information (along a direction perpendicular to the X direction and the Z direction shown in Figure 3 ).

[0142] A first detection device (not shown in the figure) connected to the control center is arranged below the conveying surface of the conveying roller 1, and the position of the first detection device is matched with the paint spraying unit 2, which is used to detect in real time whether the plate 100 is conveyed to the vicinity of the paint spraying unit 2 and send the detection result to the control center, so that the control center controls the operation of the paint spraying unit 2 according to the detection result. The control center acquires the signal of the first detection device in real time. When the first detection device detects the plate 100, it means that the plate 100 reaches the position corresponding to the paint spraying device 21. At this time, the control center controls the paint spraying device 21 to act according to the generated movement trajectory of the spray gun 211, and drives the spray gun 211 to act according to the generated movement trajectory, so as to complete the paint spraying and covering protection on the cutting surface of the plate 100. Then, with the operation of the conveying roller 1, the plate 100 enters the drying device 23 to dry the cutting surface subjected to paint spraying, so as to ensure the effect of paint spraying and covering protection.

[0143] In an optional embodiment, during the process of paint spraying on the cutting surface of the plate 100 and the process of drying the primer on the cutting surface of the plate 100, the conveying roller 1 can keep conveying or can pause conveying.

[0144] With reference to Figure 3 and Figure 4 , the driving component 212 of the paint spraying device 21 comprises a moving assembly 2121 and a rotating assembly 2122 connected with the moving assembly 2121, the moving assembly 2121 is used to drive the rotating assembly 2122 to move, and the rotating assembly 2122 is connected with the spray gun 211 and used to drive the spray gun 211 to rotate.

[0145] In one embodiment, the moving assembly 2121 of the driving component 212 comprises an X-axis translation structure 2121a and a Y-axis translation structure 2121b, the X-axis translation structure 2121a is installed on the mounting frame 24, the Y-axis translation structure 2121b is installed on the X-axis translation structure 2121a, and the Y-axis translation structure 2121b is connected with the spray gun 211, the Y-axis translation structure 2121b is driven to translate in the X-axis direction by the action of the X-axis translation structure 2121a, and the spray gun 211 connected with the Y-axis translation structure 2121b is driven to translate in the Y-axis direction by the action of the Y-axis translation structure 2121b. Wherein, the X-axis and the Y-axis are located in the horizontal plane, and there is an included angle between the X-axis and the Y-axis. For example, the included angle between the X-axis and the Y-axis is 90°, that is, the X-axis direction is the conveying direction of the conveying roller 1, and the Y-axis direction is the vertical direction of the conveying direction.

[0146] In this embodiment, with reference to Figure 3 and Figure 4 , the conveying direction (the longer side) of the plate 100 is taken as the X-axis, and the X-axis translation structure 2121a is arranged to be connected with the conveying roller 1 or other mounting structure, thereby driving the Y-axis translation structure 2121b to translate in the X-axis direction. Based on the length of the plate 100 in the conveying direction being greater than its width in the production process, the extension of the X-axis translation structure 2121a in the Y direction is shorter, thereby improving the safety of the device. It can be understood that in some possible embodiments, the Y-axis translation structure 2121b can be connected with the conveying roller 1 or other mounting structure, and the X-axis translation structure 2121a can be installed on the Y-axis translation structure 2121b, and the X-axis translation structure 2121a is connected with the spray gun 211.

[0147] In the above embodiments, a plurality of spray guns 211 need to be arranged in the vertical direction to realize the spraying of the periphery of the plate 100 by only the X-axis translation structure 2121a and the Y-axis translation structure 2121b.

[0148] In one embodiment, the moving assembly 2121 of the driving component 212 further comprises a Z-axis translation structure 2121c, and the Z-axis extends in the vertical direction. Specifically, as Figure 3 and Figure 4As shown, the Z-axis translation structure 2121c is connected with the Y-axis translation structure 2121b, and the Z-axis translation structure 2121c is connected with the spray gun 211, and the Z-axis translation structure 2121c is configured to drive the spray gun 211 to translate in the Z-axis direction.

[0149] In the embodiment, only one spray gun 211 is needed to be arranged in the vertical direction (Z-axis direction), and through the cooperation of the X-axis, Y-axis and Z-axis and the spray gun 211 movement trajectory generated by the main control end, the spray gun 211 can be translated to each position of the paint spraying operation, the position of the spray gun 211 and the distance from the spray head to the surface of the plate 100 can be adjusted according to the height of the plate 100, the waste of primer and the pollution of the environment can be avoided, and the spraying quality can be improved.

[0150] In the embodiment, when the spray gun 211 is used for spraying, the primer sprayed by the spray gun 211 is a triangular sector from the side, and the model of the spray gun 211 is, for example, the automatic spray gun of the Japanese Iwatani series.

[0151] In one embodiment, the rotating assembly 2122 of the driving component 212 includes a Z-axis rotating structure (not shown in the figure), the Z-axis rotating structure is connected with the Y-axis translation structure 2121b, and the Z-axis rotating structure is further connected with the spray gun 211, and the Z-axis rotating structure is configured to drive the spray gun 211 to rotate around the Z-axis as the rotation axis. Specifically, in the paint spraying operation, after the spray gun 211 sprays one cutting surface of the plate 100, the spray gun 211 needs to spray the adjacent other cutting surface, the spray gun 211 can be driven by the Z-axis rotating structure to rotate the spray head of the spray gun 211 by a preset angle, and then the other side of the plate 100 can be sprayed, and the preset angle is, for example, 90°.

[0152] With reference to Figure 5 , the rotating assembly 2122 further includes an A-axis rotating structure 2122b, the A-axis rotating structure 2122b is connected with the Z-axis rotating structure, and the spray gun 211 is installed on the A-axis rotating structure 2122b, and the A-axis rotating structure 2122b is configured to drive the spray gun 211 to rotate around the A-axis. The A-axis is perpendicular to the Z-axis, and the spray head of the spray gun 211 is directed to the plane perpendicular to the A-axis. In one example, the spray gun 211 is driven by the A-axis rotating structure 2122b to rotate around the A-axis by a preset angle, so that the spray head of the spray gun 211 is directed to the ground, and then the upper surface of some plates 100 is selectively sprayed with primer, and the preset angle is, for example, 90°.

[0153] In another example, after the plate 100 is sprayed with primer, the spray gun 211 is driven by the A-axis rotating structure 2122b to rotate around the A-axis by a preset angle, so that the spray head of the spray gun 211 is directed to the ground, and the spray gun 211 is connected with a clean water tank (not shown), and the driving component 212 drives the spray gun 211 to move, so as to clean the transmission roller of the conveying roller way 1.

[0154] It should be noted that when the moving assembly 2121 of the driving component 212 is provided with the Z-axis translation structure 2121c, the rotating structure needs to be connected with the Y-axis translation structure 2121b through the Z-axis translation structure 2121c.

[0155] In one embodiment, the X-axis translation structure 2121a includes a first driving motor (not shown) and a first lead screw (not shown) connected with the first driving motor, the first lead screw extending along the X-axis direction and being used for converting the torque output by the first driving motor into the linear motion of the spray gun 211 in the X-axis direction; the Y-axis translation structure 2121b includes a second driving motor (not shown) and a second lead screw (not shown) connected with the second driving motor, the second lead screw extending along the Y-axis direction and being used for converting the torque output by the second driving motor into the linear motion of the spray gun 211 in the Y-axis direction; the Z-axis translation structure 2121c includes a third driving motor (not shown) and a third lead screw (not shown) connected with the third driving motor, the third lead screw extending along the Z-axis direction and being used for converting the torque output by the third driving motor into the linear motion of the spray gun 211 in the Z-axis direction; and the Z-axis rotating structure includes a fourth driving motor (not shown) and a transmission rod (not shown) connected with the fourth driving motor, the transmission rod extending along the Z-axis direction and being used for transmitting the torque output by the third driving motor to the spray gun 211 to drive the spray gun 211 to rotate around the Z-axis. It can be understood that the A-axis rotating structure 2122b can be implemented by using the same transmission device as the Z-axis rotating structure.

[0156] In the embodiment, the Z-axis translation structure 2121c is provided with a hollow tube arranged axially and vertically, so that the transmission rod of the Z-axis rotating structure passes through the hollow tube. Specifically, the top end of the transmission rod is provided with the fourth driving motor, and the bottom end of the transmission rod is provided with the A-axis rotating structure 2122b.

[0157] In some possible embodiments, the X-axis translation structure 2121a and the Y-axis translation structure 2121b can use a drag chain as the transmission device for translation, and the Z-axis translation structure 2121c can use a telescopic cylinder as the transmission device.

[0158] In one exemplary embodiment, the paint spraying unit 2 further includes a mounting rack 24, and the paint spraying device 21 is arranged at the corresponding position of the conveying roller way 1 through the mounting rack 24.

[0159] Exemplarily, the mounting rack 24 comprises a first beam 241, a second beam 242 and two n-shaped frames 243 arranged in parallel and spaced apart along the conveying direction of the conveying roller way 1, the n-shaped frame 243 comprises an upper beam 2431 and two vertical beams 2432 connected to two ends of the upper beam 2431 respectively, and the two vertical beams 2432 of the n-shaped frame 243 are connected to the first beam 241 and the second beam 242 respectively. The paint spraying device 21 of the paint spraying device 21 is arranged on the first beam 241 and the second beam 242, and specifically, the X-axis translation structure 2121a of the paint spraying device 21 is arranged on the first beam 241 and the second beam 242 to drive the Y-axis translation structure 2121b to move along the conveying direction (X-axis direction) of the conveying roller way 1.

[0160] The plate 100 shape detection assembly (not shown) comprises a first detection element (not shown), a second detection element (not shown) and a third detection element (not shown) mounted on the mounting rack 24. The first detection element is used to identify the height information of the plate 100, the second detection element is used to identify the width information of the plate 100, and the third detection element is used to identify the position information of the plate 100 to locate the plate 100.

[0161] As shown in Figure 2 and Figure 3 , the first detection element is mounted on the upper beam 2431 of the n-shaped frame 243, and when the conveying roller way 1 conveys the head of the plate 100 directly below the first detection element, the height information of the plate 100 can be detected, wherein the first detection element can be a distance measuring sensor. The principle of measuring the height information: the height H of the first detection element is stored in the host control end, the distance between the first detection element and the upper surface of the plate 100 is L, and then the height h of the plate 100 is H-L. Figure 2 As shown in Figure 2 , the second detection element is provided with two and is mounted on the two vertical beams 2432 of the n-shaped frame 243 respectively, and when the conveying roller way 1 conveys the head of the plate 100 between the two second detection elements, the width information of the plate 100 can be detected, wherein the second detection element can be a distance measuring sensor. The principle of measuring the width information: the distance W between the two second detection elements is stored in the host control end, the distances between the two second detection elements and the side of the plate 100 are L1 and L2 respectively, and then the width w of the plate 100 is W-L1-L2.

[0162] Wherein, the detection state of the first detection element or the second detection element or the third detection element is changed from not detecting the plate 100 to detecting the plate 100, the control center starts timing, and when the detection state of the first detection element or the second detection element or the third detection element is changed from detecting the plate 100 to not detecting the plate 100, the control center stops timing, and the length of the plate 100 is determined according to the timing time and the conveying speed of the conveying roller 1.

[0163] Specifically, when the first detection element or the second detection element or the third detection element detects the head information of the plate 100, the electric signal is continuously sent to the main control end, and the start signal is also sent to the distance encoder. The distance encoder is arranged on the output shaft of the speed reducer motor (not shown in the figure), and can continuously send pulse signals according to the rotation of the output shaft of the speed reducer motor. When the first detection element and the second detection element detect the tail information of the plate 100, the electric signal is stopped sending to the main control end, and the stop signal is also sent to the distance encoder. The main control end calculates the length information of the plate 100 according to the length of time when the electric signal is received and the number of pulse signals sent by the distance encoder within the time.

[0164] In the embodiment, any one of the first detection element, the second detection element and the third detection element can be arranged to detect the head and tail information of the plate 100 to calculate the length information of the plate 100. Any two can be combined, or all three can be arranged at the same time to improve the accuracy of detection.

[0165] In the embodiment, as shown in Figure 3 The control center stores the reset origin coordinates of the spray gun 211 and the spraying waiting point coordinates. The reset origin is located at the upper left corner of the paint spraying device 21, and the spraying waiting point is located at the lower right corner of the paint spraying device 21. The control center can generate the movement trajectory of the spray gun 211 according to the size information of the plate 100 obtained by the plate 100 shape detection assembly. The movement trajectory is determined based on the reset origin coordinates. The starting point of the movement trajectory is the spraying starting point, which is located at the lower right corner of the paint spraying device 21. By setting the reset origin and the spraying starting point on the diagonal line of the plate 100, the spray gun 211 can walk through all the spraying trajectories during the reset process of the spray gun 211, so as to ensure the working stability of the spraying mechanism.

[0166] The spraying waiting point is a coordinate point preset by the worker, and the distance between the spraying waiting point and the side of the plate 100 is greater than the distance between the spraying starting point and the side of the plate 100. Before the spraying operation, the spray gun 211 is located at the spraying waiting point. By setting the spraying waiting point close to the spraying starting point, after the control center generates the movement trajectory of the spray gun, the spray gun can quickly move from the spraying waiting point to the spraying starting point and perform the spraying operation, which speeds up the start speed of the paint spraying operation and improves the working efficiency.

[0167] In this embodiment, the control center determines the number of reciprocations of the spray gun 211 on each side and the vertical displacement (Z-axis direction) between reciprocating movements based on the height information of the plate 100. The control center determines the movement displacement of the spray gun 211 on one side of the width direction based on the width information of the plate 100. The control center determines the movement displacement of the spray gun 211 on one side of the length direction based on the length information of the plate 100.

[0168] like Figures 3 to 5 As shown, when spraying with the spray gun 211, the primer sprayed out appears as a triangular fan shape when viewed from the side. In one example, when the shape detection component of the board 100 obtains the board 100 size information as a height of 700mm, the main control unit controls the X-axis translation structure 2121a and Y-axis translation structure 2121b of the drive component to move with a small rectangular trajectory so that the spray gun 211 approaches the side of the board 100 (i.e. the cutting surface), so that the spray gun 211 moves on each side of the board 100 and sprays 3 times, that is, the spray width is 700 / 3mm each time. In another example, the dimensions of the sheet material 100 are 800mm in height. The main control unit controls the X-axis translation structure 2121a and Y-axis translation structure 2121b of the drive component 212 to move along a large rectangular trajectory, so that the spray gun 211 moves away from the side (i.e., the cut surface) of the sheet material 100. Even with three coats, the cut surface of the sheet material 100 can still be coated. Similarly, when the height of the sheet material 100 is 900mm, the main control unit controls the X-axis translation structure 2121a and Y-axis translation structure 2121b of the drive component 212 to move along an even larger rectangular trajectory, so that the spray gun 211 moves further away from the side of the sheet material 100. That is, the main control unit controls the movement range threshold of the X-axis translation structure 2121a and Y-axis translation structure 2121b based on the height information of the sheet material 100, thereby automatically adjusting the number of coats for different sizes of sheet material 100, improving coating efficiency and coating quality.

[0169] The spraying stroke of the spray gun 211 can be adjusted and controlled according to the specifications of the board 100 and the number of sprayings required for the exposed parts around the board 100. Factors affecting the number of sprayings include ambient temperature and humidity.

[0170] In one embodiment, such as Figure 3 As shown, when the detection status of the first and second detection elements changes from detecting board 100 to not detecting board 100, the control center starts timing. When the timing reaches the preset duration, the control center controls the conveyor roller 1 to stop conveying. The preset duration is, for example, 0.2 seconds, and this duration can be adjusted according to actual needs.

[0171] In one embodiment, such as Figure 3As shown, the third detection element is arranged at two intervals along the conveying direction of the conveying roller 1. When the tail end of the plate 100 is detected between the two third detection elements, the control center controls the conveying roller 1 to stop conveying. Specifically, the third detection element is two photoelectric switches. When the signal emitted by the photoelectric switch is blocked by the plate 100, a signal is sent to the main control end. When the signal is not blocked by the plate 100, no signal is sent to the main control end. Based on the foregoing principle, the scheme of this embodiment is explained in detail with reference to Figure 2 Based on the sequence of the plate 100 conveying in turn, the two photoelectric switches are defined as the first photoelectric switch and the second photoelectric switch. With the operation of the conveying roller 1, the first photoelectric switch detects the plate 100 first, and then the second photoelectric switch detects the plate 100 (at this time, both photoelectric switches detect the plate 100). Then the tail of the plate 100 leaves the first photoelectric switch (only the second photoelectric switch detects the plate 100). When the main control end only receives the second photoelectric switch, that is, when the tail of the plate 100 is located between the first photoelectric switch and the second photoelectric switch, the main control end controls the conveying roller 1 to stop conveying and parks the plate 100 to the designated position. In one example, the distance between the first photoelectric switch and the second photoelectric switch is 4 cm. The distance can be adjusted according to actual needs.

[0172] In the foregoing two embodiments for controlling the conveying roller 1 to stop working, any one of them can be arranged alone, or a preset time length can be set to control the plate 100 to stop, and the detection condition of the third detection element is used as a verification signal to improve the accuracy of parking the plate 100.

[0173] In one embodiment, as shown in Figure 5 The paint spraying unit 2 further includes a paint storage device 22, a spraying electromagnetic valve 221, and an electromagnetic flowmeter 222. As shown in Figure 2As shown, the paint storage device 22 has a stirring function, and at least two paint storage devices 22 are provided, at least two paint storage devices 22 can alternately provide the primer for the spray gun 211 of the paint spraying device 21, the paint spraying electromagnetic valve 221 and the electromagnetic flow meter 222 are arranged on the pipeline connected with the paint storage device 22 and the spray gun 211, the electromagnetic flow meter 222 is used to measure the amount of primer supplied to the spray gun 211 by the paint storage device 22, and the paint spraying electromagnetic valve 221 is used to control which paint storage device 22 supplies paint to the spray gun 211. In an example, two paint storage devices 22 are provided, and the paint storage device 22 is a stainless steel stirring tank with a capacity of 50 liters, and the tank body is designed in a sealed structure to prevent dust. The total amount of primer in the paint storage device 22 is determined by the amount of work of the front-end equipment (plate cutting unit 60), when the front-end equipment is full, in order to paint all the cut plates 100, two paint storage devices 22 with a capacity of 50 liters can be provided to supply paint to the spray gun 211 of the paint spraying device 21, and specifically, when the primer in one of the paint storage devices 22 is used up, the paint spraying electromagnetic valve 221 connected therewith is closed, and the paint spraying electromagnetic valve 221 connected with the other paint storage device 22 is opened, so as to switch to the other paint storage device 22 to supply paint to the spray gun 211.

[0174] As shown in Figure 6 , the paint spraying unit 2 further comprises an environmental protection device 25, and the environmental protection device 25 comprises a spray tower 251, a waste gas treatment device 252 and a waste water recovery device (not shown). Referring to Figure 3 and Figure 6 , after the spray gun 211 of the paint spraying device 21 completes the primer spraying on the plate 100, the conveying roller 1 drives the plate 100 to move away from the paint spraying device 21, and the spray tower 251 is started to spray cleaning liquid on the paint spraying device 21 to clean the primer remaining on the paint spraying device 21 during the spraying process, thereby prolonging the service life of the paint spraying device 21. Referring to Figure 6 , when the spray tower 251 sprays cleaning liquid on the spray gun 211 of the paint spraying device 21, residual primer can be carried into the waste water recovery device of the environmental protection device 25 during the cleaning process of the spray gun 211, and the waste water recovery device collects waste water for use in the production line of the plate 100. Referring to Figure 6 , the waste gas treatment device 252 comprises a centrifugal fan 2521, a light-oxygen activated carbon integrated machine 2522, a filter cotton box 2523 and a demister 2524, the centrifugal fan 2521 drives air flow, and the light-oxygen activated carbon integrated machine 2522 and the filter cotton box 2523 can adsorb and filter primer particles and dust in the air, and the demister 2524 and activated carbon can adsorb moisture, sulfuric acid and sulfur dioxide and other substances in the air, and the purified gas is discharged to the outside, wherein the discharged industrial gas meets the atmospheric pollution emission standard.

[0175] As shown in Figure 3As shown, the drying device 23 is located between the paint spraying device 21 and the covering unit 3, which is used to dry the sprayed primer on the plate 100 after the plate 100 is sprayed with the primer in the paint spraying device 21, so as to accelerate the adhesion and solidification of the primer. The drying device 23 comprises a tunnel oven 231 and two heat preservation curtains 232, which are arranged at the inlet and outlet of the tunnel oven 231 respectively, and are used to isolate the inside and outside of the tunnel oven 231, so as to improve the temperature stability of the inside space of the tunnel oven 231. For example, the conveying roller 1 runs through the inside of the tunnel oven 231, and the conveying roller 1 directly conveys the plate 100 after the paint spraying to the inside of the tunnel oven 31, so as to dry the primer on the plate 100.

[0176] The drying temperature and drying time of the tunnel oven 231 can be adjusted according to the environmental temperature, humidity and the like, and the drying temperature is 30-100°C, and the drying time is 1-10 minutes. Among them, the drying device 23 and the paint spraying device 21 are controlled by independent power supply (not shown), and in some high temperature and dry environment, the plate 100 after the paint spraying can not be dried.

[0177] For example, the drying device 23 further comprises a plurality of circulating fans 233, and the circulating fans 233 are arranged in four groups. When the four groups of circulating fans 233 work, the hot air in the tunnel oven 231 is circulated, so as to improve the drying effect.

[0178] In some embodiments, the drying device 23 is further provided with a preheating device (not shown), and the preheating device comprises an infrared temperature measuring element (not shown) and a temperature rising element (not shown) connected with the infrared temperature measuring element. The preheating device stores a preset temperature, the infrared temperature measuring element detects the surface temperature of the plate 100 in real time, and when the detected temperature is lower than the preset temperature, the infrared temperature measuring element sends a starting signal to the temperature rising element until the infrared temperature measuring element detects that the surface temperature of the plate 100 reaches the preset temperature, and then sends a stopping signal to the temperature rising element.

[0179] In the decorative plate production system of the embodiment, as shown in Figure 1-2 The covering unit 3 comprises a pasting mechanism 301, a laser cutting mechanism 41, a first pressing mechanism 5 and a first cutting mechanism 42, which are arranged in sequence along the conveying direction of the conveying roller 1, wherein,

[0180] The pasting mechanism 301 pastes the decorative material 200 to the decorative surface of the plate 100, so as to realize the decorative effect of the plate 200 and improve the appearance of the plate.

[0181] The laser cutting mechanism 41 is used to cut the edge of the decorative material 200 into a preset shape of a gap, so that the decorative material 200 can be better wrapped on the decorative surface and the cutting surface of the plate 100.

[0182] The first pressing mechanism 5 includes a plurality of pressing rollers 50 arranged in sequence on both sides of the conveying roller 1 and gradually changing in angle along the conveying direction of the conveying roller 1, and is used to press the edge of the decorative material 200 and the side surface and the bottom surface of the plate 100. In the embodiment, the side surface of the plate 100 is the cutting surface of the plate 100 corresponding to the edge of the decorative material 200, and the bottom surface is opposite to the decorative surface.

[0183] The first cutting mechanism is used to cut the position of the decorative material 200 between adjacent plates 100 along the width direction of the decorative material 200, so as to facilitate the decorative material 200 to cover and decorate the end surface and the bottom surface of the plate 100. In the embodiment, the end surface of the plate 100 is the cutting surface of the plate 100 corresponding to the cut end of the decorative material 200, and the bottom surface is opposite to the decorative surface.

[0184] Figure 7 The structure diagram of a specific embodiment of the pasting mechanism 301 is shown, which includes a first unwinding device 31, a glue applying device 32 and a first roller pressing device 33 arranged in sequence along the conveying direction of the plate 100, and the first unwinding device 31 and the glue applying device 32 are operated under the control of the control center. Among them, the first unwinding device 31 is located above the glue applying device 32, and under the control of the control center, the first unwinding device 31 releases the decorative material 200 at a predetermined speed suitable for the conveying speed of the conveying roller 1, so as to ensure that the decorative material 200 and the plate 100 run synchronously along the conveying direction of the conveying roller 1. The glue applying device 32 is used to apply the bonding agent to the bonding surface of the decorative material 200, so as to ensure the bonding firmness of the decorative material 200 and the plate 100. The first roller pressing device 33 is used to press the decorative material 200 on the decorative surface of the plate 100, so as to ensure that the decorative material 200 and the decorative surface of the plate 100 are fully, uniformly and firmly pasted.

[0185] As shown in Figure 7 The glue applying device 32 includes a hot melt glue machine 320, a glue applying groove 321, a glue applying knife 322 and a glue applying cylinder 323. The hot melt glue machine 320 is located on one side of the conveying roller 1, and is used to heat the bonding agent for bonding and fixing the decorative material 200 and the plate 100, and deliver it to the glue applying knife 322. The glue applying cylinder 323 is connected with the control center signal, the glue applying knife 322 is connected with the output end of the hot melt glue machine 320 and is fixedly connected with the output end of the glue applying cylinder 323, and the glue applying knife 322 is arranged corresponding to the glue applying groove 321. In the illustrated embodiment, when the output end of the glue applying cylinder 323 is withdrawn, the glue applying knife 322 applies glue to the glue applying groove 321.Figure 7 As shown, the applied veneer material 200 in production is guided to pass through the glue applying groove 321, the control center controls the hot-melt glue machine 320 to heat the bonding agent and supply the heated bonding agent to the glue applying knife 322, and controls the output end of the glue applying cylinder 323 to retract, driving the glue applying knife 322 to coat the bonding agent on the veneer material 200 passing through the glue applying groove 321.

[0186] The veneer material 200 coated with the bonding agent by the glue applying device 32 is guided to the first roller pressing device 33 to be attached to the decorative surface of the board 100 being conveyed. Specifically, the first roller pressing device 33 includes at least one carrier roller 331 and at least one pressing roller 332, the upper conveying surface of the carrier roller 331 is in the same plane as the conveying surface of the conveying roller 1, and the pressing roller 332 is located above the carrier roller 331, i.e. the axis of the pressing roller 332 is perpendicular to the plane formed by the axis of the carrier roller 331 and the conveying surface of the conveying roller 1, and the spacing between the pressing roller 332 and the carrier roller 331 is equal to the thickness sum of the board 100 and the veneer material 200. The board 100 being conveyed and the veneer material 200 are jointly conveyed between the carrier roller 331 and the pressing roller 332, and the veneer material 200 is attached and bonded to the board 100 under the pressing of the pressing roller 332. In the embodiment shown, the first roller pressing device 33 includes two carrier rollers 331 and two pressing rollers 332 arranged side by side, the top common tangent planes of the two carrier rollers 331 are in the same plane as the conveying surface of the conveying roller 1, and the two pressing rollers 332 are respectively located above the two carrier rollers 331. The veneer material 200 coated with the bonding agent and the board 100 to be decorated are sequentially pressed between the two carrier rollers 331 and the two pressing rollers 332, effectively ensuring the firmness and flatness of the attachment between the veneer material 200 and the decorative surface of the board 100. The width of the pressing roller 332 is greater than the width of the board 100 to ensure that the veneer material 200 is completely attached to the decorative surface of the board 100. Figure 6

[0187] In order to ensure the decoration effect, it is necessary to clean the board 100 before attaching the veneer material 200, to ensure the cleanliness and flatness of the decorative surface of the board 100, to ensure the complete attachment between the board 100 and the veneer material 200, and to ensure the attachment quality and decoration effect. Exemplarily, as shown in Figure 1-2 As shown, a cleaning device 112 is further provided between the heating mechanism 31 and the cladding unit 3, for cleaning the dust or gypsum stains and other impurities on the decorative surface of the board 100.

[0188] Further, as shown in Figure 1-2 ​As shown, the conveying roller 1 is provided with a aligning roller 111 between the heating mechanism 31 and the covering unit 3, so as to align the plate 100 to be decorated to one side along the conveying direction of the conveying roller 1, so as to ensure the alignment of the plate 100 and the veneer 200, and avoid the position deviation or skew between the plate 100 and the veneer 200, which affects the decoration effect.

[0189] Figure 8 The structure diagram of one specific embodiment of the aligning roller 111 is shown, which is described with reference to Figure 8 As shown, the arrow direction in the figure is the conveying direction of the conveying roller 1, and in this embodiment, the aligning roller 111 includes a plurality of inclined rollers 111a arranged at intervals along the conveying direction, and the inclined rollers 111a are arranged at an acute angle with the limiting piece 111b on one side along the conveying direction. In the conveying process of the aligning roller 111, the plate 100 is aligned and conveyed to the limiting piece 111b on one side through the inclined rollers 111a, and is blocked and limited by the limiting piece 111b, so as to ensure the alignment of the plate 100 and the veneer 200, and avoid the skew between the plate 100 and the veneer 200.

[0190] The decorative plate produced by the decorative plate production system of this embodiment not only covers and decorates the decorative surface of the plate 100 through the veneer 200, but also covers and decorates the cutting surface of the plate 100, and fixes the edge of the veneer 200 on the bottom surface (i.e. the opposite surface of the decorative surface) of the plate 100, so as to fully ensure the decoration effect and the adhesion firmness of the veneer 200. However, since the veneer 200 is also a product with a certain width, it is still rectangular after cutting in production, and if the decorative surface and the cutting surface of the plate 100 are to be covered and decorated, the excess part of the four corners needs to be cut online.

[0191] Figure 9 The structure diagram of the veneer 200 of the decorative plate produced by the decorative plate production system of this embodiment is shown after being unfolded, Figure 10 The cutting shape diagram of the laser cutting device in one exemplary embodiment is shown. Figure 11 The structure diagram of one specific embodiment of the laser cutting mechanism 41 in this application is shown, and the conveying roller 1 conveys the plate 100 along the arrow direction shown in the figure.

[0192] The structure diagram of one specific embodiment of the laser cutting mechanism 41 in this application is shown, and the conveying roller 1 conveys the plate 100 along the arrow direction shown in the figure. Figure 11As shown, the laser cutting mechanism 41 is used for online cutting of the facing material 200 on the plate 100, which includes a cutting controller 411, a speed measuring device 412, a first sensor 413 and a second sensor 414 arranged in sequence along the conveying direction of the conveying roller 1, and a laser cutting machine 415. The laser cutting machine 415, the first sensor 413, the second sensor 414 and the speed measuring device 412 are electrically connected with the cutting controller 411, the cutting controller 411 controls the operation of the laser cutting machine 415 according to the detection results of the first sensor 413, the second sensor 414 and the speed measuring device 412, and the cutting controller 411 is signal-connected with the control center to control the start and stop of the cutting controller 411.

[0193] It should be noted that, since the present scheme is applied to online cutting of the facing material 200 on the plate 100, the two side edges of the facing material 200 between adjacent plates 100 on the conveying roller 1 need to be cut symmetrically, therefore, the laser cutting machine 415 in the present scheme is arranged in pairs, for example, one or several pairs of laser cutting machines 415 are arranged along the conveying direction of the product conveying line. In the present embodiment, two laser cutting machines 415 are oppositely arranged on both sides of the conveying roller 1 to symmetrically cut the facing material 200.

[0194] The present scheme uses the first sensor 413 and the second sensor 414 arranged along the conveying direction of the conveying roller 1 to detect the end position of the plate 100 in real time, at the same time, uses the speed measuring device 412 to detect the conveying speed of the conveying roller 1, i.e. the moving speed of the plate 100, the cutting controller 411 combines the position detection result of the plate 100 and the conveying speed detection result to accurately determine the position required to be cut of the facing material 200, and uses it as the basis to control the start and stop of cutting, controls the laser cutting machine 415 to cut according to the predetermined shape, and effectively guarantees the cutting accuracy and completeness.

[0195] In the present embodiment, the first sensor 413 and the second sensor 414 are both located below the conveying roller 1, and the second sensor 414 is flush with the laser cutting machine 415 or is located between the first sensor 413 and the laser cutting machine 415, and the interval between the first sensor 413 and the second sensor 414 is less than the length of a plate 100 being conveyed on the conveying roller 1. The plate 100 being conveyed first passes through the first sensor 413 and then passes through the second sensor 414, the first sensor 413 detects the interval between the adjacent two plates 100 and sends it to the cutting controller 411, the cutting controller 411 determines the cutting length of the laser cutting machine 415 this time according to the detection result of the first sensor 413; when the second sensor 414 detects the end signal of the plate 100, it sends it to the cutting controller 411, and the cutting controller 411 starts the laser cutting machine 415 to cut according to the preset trajectory shape.

[0196] Specifically, the cutting controller 411 receives the detection result of the first sensor 413 in real time. For example, the first sensor 413 can be a distance sensor, which is preset to detect the distance between the detection end and the conveying surface of the conveying roller 1 (equivalent to the bottom surface of the conveying board 100). When the first sensor 413 detects the surface of the board 100, a continuous electrical signal is sent. When the previous board 100 exceeds the position of the first sensor 413, i.e., the first sensor 413 is located between the adjacent two boards 100, no detection signal is sent. The cutting controller 411 determines the time length of the part between the adjacent two boards 100 conveyed above the first sensor 413, and combines the conveying speed of the product detected by the speed detection device 412 to calculate the interval between the adjacent two boards 100, and further obtain the cutting length of the laser cutting machine 415 in this cutting process.

[0197] During conveying, the speed detection device 412 is used to detect the conveying speed of the product on the conveying roller 1 in real time and send it to the cutting controller 411. The cutting controller 411 combines the detection result of the first sensor 413 with the detection result of the speed detection device 412, i.e., the cutting controller 411 combines the interval between the adjacent boards 100 with the conveying speed of the board 100, controls the operation of the laser cutting machine 415, so as to fully guarantee the shape and cutting precision after cutting, and guarantee the cutting position of the laser cutting machine 415 aligns with the edge of the board 100.

[0198] In actual production process, in order to further guarantee the cutting quality and the decoration quality after the board 100 and the veneer material 200 are pasted, the cutting position of the laser cutting machine 415 and the edge of the board 100 can be reserved a certain amount, for example, 0.412-1mm, and exemplarily, 0.5mm can be set. For example, in the conveying direction, the cutting starting position of the laser cutting machine 415 controlled by the cutting controller 411 can be 0.5mm after the tail end of the previous board 100, and the cutting end corresponds to 0.5mm before the end of the next board 100.

[0199] It should be pointed out that, considering safety production, the laser emission direction of the laser cutting machine 415 is towards the ground, i.e., the cutting head position of the laser cutting machine 415 is higher than the product position on the conveying roller 1, and the veneer material 200 is cut vertically from top to bottom.

[0200] Referring to Figures 9-11As shown, in order to meet the online decoration production requirements of the plate 100, the laser cutting machine 415 cuts the shape of a rectangular notch. As before, the cutting length of the laser cutting machine 415 is controlled by the cutting controller 411 according to the detection result of the first sensor 413. Further, the cutting trajectory of the laser cutting machine 415 is controlled by the cutting controller 411 according to the detection result of the first sensor 413 in combination with the detection result of the speed measuring device 412.

[0201] Since the cutting speed of the laser cutting machine 415 is very fast, when the conveying speed of the conveying roller 1 detected by the speed measuring device 412 is low, if the shape error after cutting by the laser cutting machine 415 running on a rectangular trajectory is within the allowable range, the laser cutting machine 415 can be controlled to cut according to the rectangle; and when the current conveying speed of the conveying roller 1 detected by the speed measuring device 412 is fast, and this conveying speed is sufficient to cause the error after cutting by the laser cutting machine 415 running on a rectangular trajectory to affect the production effect, the cutting controller 411 controls the actual running trajectory of the laser cutting machine 415 to be a trapezoid, for example, an isosceles trapezoid, and the long side of the trapezoid is a trajectory parallel to the edge of the decorative material 200 and cut in the decorative material 200.

[0202] In the present embodiment, the speed measuring device 412 includes a speed measuring wheel 4121 located above the product (the product formed by the decorative material 200 attached to the decorative surface of the plate 100) of the conveying roller 1, and an encoder 4122 connected with the speed measuring wheel 4121 and electrically connected with the cutting controller 411. Specifically, the edge of the speed measuring wheel 4121 is attached to the surface of the product (the surface of the decorative material 200), and rotates synchronously with the product as the product is conveyed, and the encoder 4122 converts the rotation speed of the speed measuring wheel 4121 into an electrical signal and sends it to the cutting controller 411, which receives it and controls the operation of the laser cutting machine 415 in combination with the detection result of the first sensor 413.

[0203] In the decorative plate production system provided in the present embodiment, the laser cutting device 41 is used to cut the edge of the decorative material 200 into a predetermined shape, and the decorative material 200 between adjacent plates 100 is still in an integrated state, so it needs to be cut off. The covering unit 3 of the present scheme further includes a first cutting-off mechanism 42 for cutting off the decorative material 200 at the position between adjacent plates 100 along the width direction of the decorative material 200. In order to ensure that the decorative material 200 on both sides of the plate 100 is attached flat, the decorative material 200 is cut off along its width direction after the first pressing mechanism 5 completes the pressing action, therefore, the first pressing mechanism 5 is located between the laser cutting device 41 and the first cutting-off mechanism 42 in the conveying direction of the conveying roller 1.

[0204] After the facing material 200 is coated with the bonding agent and is pressed on the decorative surface of the board 100, as the board 100 is continuously conveyed on the conveying roller 1, the edges of the facing material 200 between the adjacent boards 100 are cut into a preset shape by the laser cutting device 41, the edge of the facing material 200 is bent by the first pressing mechanism 5 and is pressed with the side surface and the bottom surface of the board 100, then the facing material 200 between the adjacent boards 100 is cut along the width direction by the first cutting device 42, and finally the two ends of the facing material 200 are pressed with the end surface and the bottom surface of the board 100 by the second pressing mechanism 6, thereby forming the decorative board.

[0205] In order to ensure the synchronization and flatness of the two side surfaces of the board 100 and the facing material 200, a set of first pressing mechanisms 5 is arranged on each side of the conveying roller 1 to simultaneously bend the two sides of the facing material 200 and press them with the side surface and the bottom surface of the board 100. Each set of first pressing mechanisms 5 includes a plurality of pressing rollers 50 arranged on one side of the conveying roller 1 in sequence along the conveying direction of the conveying roller 1, and the inclination angles of the pressing rollers 50 gradually change.

[0206] Figure 12 A distribution diagram of the pressing rollers 50 in a specific embodiment is shown. As shown in the figure, the pressing rollers 50 include at least one top surface pressing roller 501, at least one top edge pressing roller 502, at least one side surface pressing roller 503, at least one bottom edge pressing roller 504, and at least one bottom surface pressing roller 505. Figure 12-1 A position diagram of the top surface pressing roller 501 is shown, Figure 12-2 A position diagram of the top edge pressing roller 502 is shown, Figure 12-3 A position diagram of the side surface pressing roller 503 is shown, Figure 12-4 A position diagram of the bottom edge pressing roller 504 is shown, Figure 12-5A position diagram of the bottom surface pressing roller 505 is shown. Among them, the top surface pressing roller 501 is located above the plate 100 and the decorative material 200, and the edge of the decorative material 200 is fully pressed on the decorative surface of the plate 100, avoiding the edge of the decorative material 200 from being wrinkled when the decorative material 200 is bent in the subsequent process, which affects the decoration quality and decoration effect, and the axis direction of the top surface pressing roller 501 is parallel to the width direction of the plate 100. The axis direction of the top edge pressing roller 502 is arranged at an acute angle with the width direction of the plate 100, and the side wall of the top edge pressing roller 502 fully presses the decorative material 200 at the top edge (i.e. the edge of the decorative surface) of the plate 100, which is used to bend the decorative material 200 along the top edge of the plate 100 to the side of the plate 100. The axis direction of the side surface pressing roller 503 is parallel to the thickness direction of the plate 100, that is, perpendicular to the decorative surface of the plate 100, and the side wall of the side surface pressing roller 503 fully presses the decorative material 200 on the side surface of the plate 100. As the plate 100 advances, the side surface pressing roller 503 rotates, thereby fully pressing the decorative material 200 and the side surface of the plate 100. The axis direction of the bottom edge pressing roller 504 is arranged at an acute angle with the width direction of the plate 100, which is used to bend the decorative material 200 along the bottom edge of the plate 100 to the bottom surface of the plate 100; the axis direction of the bottom surface pressing roller 505 is parallel to the width direction of the plate 100 and located below the plate 100, which is used to press the decorative material 200 and the bottom surface of the plate 100.

[0207] When the top edge pressing roller 502 is two or more, the included angle between the axis of each top edge pressing roller 502 and the decorative surface of the plate 100 can be the same, or gradually increase along the conveying direction of the conveying roller 1. Correspondingly, when the bottom edge pressing roller 504 is two or more, the included angle between the axis of each bottom edge pressing roller 504 and the bottom surface of the plate 100 can be the same, or gradually decrease along the conveying direction of the conveying roller 1.

[0208] In addition, when the number of top surface pressing rollers 501 is multiple, the multiple top surface pressing rollers 501 can be arranged before the top edge pressing roller 502, or distributed between the top edge pressing roller 502 and the side surface pressing roller 503 and between the side surface pressing roller 503 and the bottom edge pressing roller 504.

[0209] After the edge of the decorative material 200 is fully pressed with the plate 100 by the first pressing mechanism 5, the decorative material 200 between adjacent plates 100 is cut by the first cutting mechanism 42 during the conveying process of the conveying roller 1, so as to press the two ends of the decorative material 200 and the plate 100 in the subsequent process.

[0210] Figure 13 A top view arrangement diagram of the first cutting mechanism 42 on the conveying roller 1 is shown, Figure 14Fig. 4 shows a lateral structural schematic diagram of the first cutting mechanism 42, and Figure 13 and Figure 14 In the embodiment, the first cutting mechanism 42 includes a tracking cutter 421 obliquely spanning above the conveying roller bed 1 and a first dust collection device 422 located below the conveying roller bed 1 and arranged along the cutting track of the tracking cutter 421, the tracking cutter 421 is used to cut the veneer 200 between adjacent boards 100 under the control of the control center as the boards 100 travel on the conveying roller bed 1, and the first dust collection device 422 is used to collect dust such as paper scraps generated during the cutting of the veneer 200 by the tracking cutter 421.

[0211] Specifically, the tracking cutter 421 includes a roller bed 4211 obliquely arranged above the conveying roller bed 1, a driving motor 4212 located at one end of the roller bed 4211, a cutting motor 4213 and a cutting blade 4214, wherein the cutting motor 4213 is in sliding connection with the roller bed 4211 and in transmission connection with the output end of the driving motor 4212, and the cutting blade 4214 is in fixed connection with the output end of the cutting motor 4213. The driving motor 4212 and the cutting motor 4213 are both in signal connection with the control center, under the control of the control center, the driving motor 4212 drives the cutting motor 4213 to drive the cutting blade 4214 to slide along the roller bed 4211, and at the same time the cutting motor 4213 drives the cutting blade 4214 to rotate at high speed to cut the veneer 200 transversely. Wherein, when the driving motor 4212 drives the cutting motor 4213 to move on the roller bed 4211 obliquely across the conveying roller bed 1 along the conveying direction of the conveying roller bed 1, the moving speed component of the cutting motor 4213 in the conveying direction of the conveying roller bed 1 is equal to the conveying speed of the conveying roller bed 1, so as to ensure that the cutting blade 4214 cuts the veneer 200 transversely perpendicular to the side surface of the board 100.

[0212] Figure 15 Fig. 4 shows a state schematic diagram of the cutting blade 4214 when cutting the veneer 200 in a specific embodiment, as shown in the figure, in order to ensure the flatness of the cutting end face, the cutting blade 4214 can adopt an ultra-thin toothless saw blade, for example, a toothless saw blade with a thickness of 1mm can be adopted, and the extension surface of the cutting blade 4214 is arranged perpendicular to the conveying direction of the conveying roller bed 1.

[0213] Referring back to Figure 13 and Figure 14As shown, since the roller bed 4211 is arranged in a slope span, in order to realize online cutting along with the operation of the conveying roller bed 1, the cutting blade 4214 can only cut in one direction. After each cutting is completed, the driving motor 4212 needs to drive the cutting motor 4213 and the cutting blade 4214 to restore to the original position, and in order to prevent damage to the veneer 200 during the restoration of the cutting blade 4214 to the original position, the cutting blade 4214 needs to be lifted to a certain height, therefore, the tracking cutting machine 421 further comprises a lifting assembly 4215, the cutting motor 4213 is fixedly connected with the output end of the lifting assembly 4215, the lifting assembly 4215 is in transmission connection with the output end of the driving motor 4212 and in sliding connection with the roller bed 4211. For example, the lifting assembly 4215 can be a lifting cylinder or other lifting or telescopic device.

[0214] A second detection device 102 connected with the control center is arranged at a position corresponding to the starting end of the tracking cutting machine 421 below the middle of the conveying surface of the conveying roller bed 1 or a position before the starting end of the tracking cutting machine 421 in the conveying direction of the conveying roller bed 1, which is used to detect the edge position of the board 100, that is, the running position of the board 100, and feedback to the control center in real time, and the control center controls the operation of the tracking cutting machine 421 according to the detection result of the second detection device 102.

[0215] The control center controls the conveying roller bed 1 to convey the boards 100 placed at a predetermined interval at a predetermined speed, and when the board 100 passes above the second detection device 102, the second detection device 102 can detect the signal of the board 100. When the board 100 completely passes above the second detection device 102, the second detection device 102 has no signal output. Therefore, when the second detection device 102 has no signal output, the control center judges that the previous board 100 has passed above the second detection device 102, and when the second detection device 102 has signal output again, it is judged that the subsequent board 100 starts to pass above the second detection device 102, and the interval between the adjacent two boards 100 in this process.

[0216] The control center calculates how long after the signal from the second detection device 102 is not received or how many pulses are missed to control the tracking cutting machine 421 to start according to the conveying interval between adjacent boards 100, the conveying speed of the conveying roller 1, and the distance between the second detection device 102 and the starting end of the tracking cutting machine 421. For example, when the previous board 100 passes above the second detection device 102, the second detection device 102 sends the detected signal to the control center in real time. When the control center does not receive the signal from the second detection device 102 for a predetermined time or calculates a predetermined number of pulses, the control center controls the driving motor 4212 and the cutting motor 4213 to start, and drives the lifting assembly 4215 to lower the cutting motor 4213 by a predetermined height stroke. As the driving motor 4212 and the cutting motor 4213 operate, the cutting blade 4214 performs cross-cutting on the veneer 200. When the driving motor 4212 operates for a predetermined stroke or operates at a predetermined speed for a predetermined time, the lifting assembly 4215 drives the cutting motor 4213 to operate to the other end of the roller 4211 across the veneer 200 on the conveying roller 1, i.e., after the cutting blade 4214 completes cutting the veneer 200, the control center controls the cutting motor 4213 to stop operating, controls the lifting assembly 4215 to raise the cutting motor 4213 by a predetermined height stroke (i.e., to restore the original height position so that the cutting blade 4214 is higher than the height position of the veneer 200), and then controls the driving motor 4212 to operate in reverse to drive the lifting assembly 4215 to stop at the starting end position on the roller 4211, and waits for the next cutting.

[0217] In actual production, the conveying roller 1 can adopt a non-powered roller structure. In order to facilitate the control of the speed of the cutting blade 4214 in the conveying direction of the conveying roller 1 to be equal to the conveying speed of the board 100, a speed measuring wheel 4231 and a speed measuring encoder 4232 are arranged above the conveying surface of the conveying roller 1. The axis direction of the speed measuring wheel 4231 is arranged along the width direction of the conveying roller 1, and the speed measuring encoder 4232 is arranged on the speed measuring wheel 4231 and is signal-connected with the control center. When the board 100 conveyed on the conveying roller 1 passes through the speed measuring wheel 4231, the speed measuring wheel 4231 is driven to rotate, and the speed measuring encoder 4232 detects the rotating speed of the speed measuring wheel 4231 in real time and converts it into an electrical signal to send to the control center, and the control center controls the cutting speed of the cutting blade 4214 driven by the driving motor 4212 according to the speed measured by the speed measuring encoder 4232.

[0218] In order to ensure the cleanliness of the production system and the surface of the product, a first dust collection device 422 is arranged below the conveying roller 1, below the roller 4211, along the extension direction of the roller 4211, and across the conveying roller 1 at the same angle as the roller 4211, for collecting the debris and dust generated by cutting the veneer 200. Figure 16A lateral structure diagram of a specific embodiment of the first dust collecting device 422 is shown. In order to ensure that the debris and dust generated during the cutting process accurately enter the first dust collecting device 422, the first dust collecting device 422 can adopt a negative pressure dust collecting structure, and the inlet adopts a funnel-shaped structure to ensure that the debris and dust can be collected to the maximum extent.

[0219] During the cutting of the veneer 200 by the cutting blade 4214, most of the debris falls into the first dust collecting device 422 for collection, and a small part of the debris is thrown up by the high-speed rotating cutting blade 4214 and falls onto the surface of the veneer 200. In order to fully ensure the cleanliness of the product surface, the first cutting-off mechanism 42 in this embodiment further includes a dust blowing device 424 and a second dust collecting device 425 located above the conveying roller 1 and beside the tracking cutting-off machine 421. The second dust collecting device 425 is a negative pressure dust collecting structure with a downward dust collecting port to fully collect dust or paper scraps on the surface of the veneer 200. The outlet of the dust blowing device 424 is located above the surface of the veneer 200 and below the dust collecting port of the second dust collecting device 425 to blow up all the dust and paper scraps on the surface of the veneer 200, further ensuring that the impurities on the surface of the veneer 200 can be fully collected. The dust blowing device 424 can use compressed air for dust blowing to ensure that all the impurities on the surface of the veneer 200 can be blown up.

[0220] Figure 17-1 A lateral structure diagram of a specific embodiment of the dust blowing device 424 is shown, Figure 17-2 A lateral structure diagram of a specific embodiment of the dust blowing device 424 is shown, In this embodiment, the dust blowing device 424 includes a compressed air pipeline 4241 and a plurality of nozzles 4242 arranged side by side and connected to the output end of the compressed air pipeline 4241. The plurality of nozzles 4242 are arranged side by side across the conveying surface of the conveying roller 1 to ensure full coverage of the dust blowing in the width direction of the veneer 200. Further, in order to fully ensure the dust blowing area and intensity, in the top view angle along the width direction of the conveying roller 1, the outlet width of the nozzle 4242 is much larger than the inlet width to ensure that the angle of the compressed air ejected from the nozzle 4242 is expanded in the width direction of the veneer 200, i.e., to ensure the dust blowing area; and in the side view angle perpendicular to the conveying surface direction of the conveying roller 1, the outlet size of the nozzle 4242 is smaller than the inlet size to enhance the pressure and intensity of the compressed air ejected from the nozzle 4242, fully ensuring the dust blowing intensity.

[0221] To save equipment cost, the second dust collection device 425 can adopt the same structure and dust collection principle as the first dust collection device 32, only need to be inverted to the dusting device 424 outlet or dusting direction above, using negative pressure dust collection, dust and paper dust blown up by the dusting device 424 are collected. Exemplarily, -5000~ -5000Pa negative pressure space can be provided in the dust collection cover of the first dust collection device 32 and the second dust collection device 425.

[0222] In order to successfully press the two ends of the cut decorative material 200 and the plate 100, the covering unit further comprises a second pressing mechanism 6. The cut decorative material 200 is continuously conveyed with the plate 100 by the turning roller 10, and when passing through the second pressing mechanism 6, the second pressing mechanism 6 presses the two ends of the cut decorative material 200 and the other two sides and the bottom surface of the plate 100, forming a decorative plate product. Since the second pressing mechanism 6 has a certain time interval from the time when the binder is coated on the decorative material 200, in order to ensure the binding property of the binder and the firmness of the press between the decorative material 200 and the plate 100, the decorative plate production system of the embodiment further comprises a secondary heating mechanism (not shown in the figure) arranged between the first cutting mechanism and the second pressing mechanism. The secondary heating mechanism is used to heat the two ends of the cut decorative material 200 before pressing by the second pressing mechanism 6, so as to fully ensure the activity of the binder. The second pressing mechanism and the secondary heating mechanism are connected with the control center signal.

[0223] In an example, the turning roller 10 is arranged on the output end of the third roller 13 and the input end of the fourth roller 14, which is used to change the conveying direction of the plate 100 from the length direction to the width direction of the plate 100, so as to realize the conversion of the plate 100 between the third roller 13 and the fourth roller 14. The second pressing mechanism 6 is arranged on the turning roller 10 along the conveying direction of the turning roller 10, and the secondary heating mechanism is arranged on both sides of the turning roller 10. Specifically, the secondary heating mechanism 7 is a hot air gun connected with the control center signal, and the control center controls the secondary heating mechanism 7 to be turned on synchronously when the turning roller 10 is started, so as to heat the two ends of the decorative material 200 on the plate 100 in conveying.

[0224] Referring back to Figure 1-2As shown, the conveying roller way 1 comprises a third roller way 13, a fourth roller way 14 and a turning roller way 10 between the third roller way 13, the conveying direction of the third roller way 13 is parallel to the conveying direction of the fourth roller way 14, and the conveying direction of the turning roller way 10 is perpendicular to the conveying direction of the third roller way 13. The input end of the turning roller way 10 is located at the output end of the third roller way 13, and the output end of the third roller way 13 is provided with a first blocking device (not shown in the figure) to prevent the plate 100 from sliding out of the third roller way 13. The first blocking device is provided with a first trigger connected with the control center signal, when the plate 100 in the conveying process hits the first blocking device and stops, the first trigger is triggered to send a signal to the control center, and the control center drives the turning roller way 10 to start after receiving the signal, and the plate 100 and the veneer 200 pressed on the plate 100 are conveyed along the turning roller way 10 for the second time, and the decorative plate is formed, and then conveyed to the fourth roller way 14. The output end of the turning roller way 10 is arranged at the input end of the fourth roller way 14, and the input end of the second conveying roller way is provided with a second blocking device (not shown in the figure) to ensure that the decorative plate is accurately conveyed on the second conveying roller way. Correspondingly, the second blocking device is provided with a second trigger connected with the control center signal, when the decorative plate stays on the second conveying roller way due to touching the second blocking device, the second trigger is triggered to send a start signal to the control center, and the control center drives the power roller assembly at the input end of the second conveying roller way to convey the decorative plate.

[0225] In a typical embodiment, the input end of the turning roller way 10 is a first conveying belt arranged between the conveying rollers of the third roller way 13, and a first lifting device is arranged below the first conveying belt. When the control center receives the signal of the first trigger, the first lifting device is started to rise to a conveying surface of the first conveying belt higher than the conveying surface of the third roller way, and then the first conveying belt is started to convey the plate 100. When the control center controls the turning roller way 10 to stop, the first lifting device drives the first conveying belt to descend below the conveying surface of the third roller way 13. Correspondingly, the output end of the turning roller way 10 is a second conveying belt arranged between the input conveying rollers of the second conveying roller way, and a second lifting device is arranged below the second conveying belt. When the turning roller way 10 is conveying, the second lifting device is in the state of rising, and the conveying surface of the second lifting belt is higher than the conveying surface of the second conveying roller way. When the control center controls the turning roller way 10 to stop, the second lifting device drives the second conveying belt to descend below the conveying surface of the second conveying roller way.

[0226] Specifically, the second pressing mechanism 6 can adopt the same component structure as the first pressing mechanism 5, including a top surface pressing roller, a top edge pressing roller, a side surface pressing roller, a bottom edge pressing roller and a bottom surface pressing roller arranged in sequence along the conveying direction of the turning roller way 10, wherein the top surface pressing roller is used to further press the two ends of the veneer 200 and the decorative surface end edges of the board 100, the top edge pressing roller is used to bend the two ends of the veneer 200 along the decorative surface end edges of the board 100, the side surface pressing roller is used to press the bent veneer 200 and the end surface of the board 100, the bottom edge pressing roller is used to bend the veneer 200 along the bottom edge of the end surface of the board 100, and the bottom surface pressing roller is used to fully press the end edges of the veneer 200 and the bottom surface of the board 100, thereby completing the pressing process of the veneer 200 and the board 100 and completing the decoration production of the board 100.

[0227] Figure 18 A structural schematic diagram of one specific embodiment of the film pasting unit 80 is shown, which includes a film pasting device 81 and a second cutting mechanism 82. The film pasting device 81 includes a second unwinding device 801 and a second roller pressing device 802, wherein the second unwinding device 801 is located above the second roller pressing device 802. The second unwinding device 801 releases the protective film 83 at a predetermined speed suitable for the conveying speed of the conveying roller way 1, so as to ensure that the protective film 83 runs synchronously with the board 100 along the conveying direction of the conveying roller way 1. The second roller pressing device 802 is used to press the adhesive protective film 83 on the veneer 200 of the board 100, and the second cutting mechanism 82 is used to cut the protective film 83 in the position between the adjacent boards 100 along the width direction of the protective film 83, so as to ensure that the protective film 83 is uniformly pasted on the decorative surface material 200. Since the boards 100 are conveyed at intervals, the film pasting unit 80 of the present embodiment operates in an intermittent waiting mode. A third detection device (not shown in the figure) connected with the control center signal is arranged at a predetermined position corresponding to the starting end of the film pasting unit 80 below the middle of the conveying surface of the conveying roller way 1, which is used to detect the position of the end edge of the board 100, i.e. the running position of the board 100, and feedback to the control center in real time. The control center controls the operation of the film pasting unit 80 according to the detection result of the third detection device. When the third detection device detects that the board 100 passes through the predetermined position, the control center controls the film pasting unit 80 to start operation. In order to ensure that the recovery operation is on time, synchronous and smooth, a servo motor is used for control driving. In the subsequent film pasting process of the board 100, the previous board 100 is conveyed to the subsequent equipment after completing the tracking cutting. The third detection device includes a first photoelectric sensor 84 and a second photoelectric sensor 85, and the interval between the adjacent boards 100 is controlled by adjusting the interval of the first photoelectric sensor 84 and the second photoelectric sensor 85. The second cutting mechanism 82 is basically the same as the first cutting mechanism 42, except that the second cutting mechanism 82 uses a blade to cut the protective film 83, and the protective film 83 is, for example, a PE film.

[0228] In actual production, whether the board 100 after decoration or the board 100 to be decorated, in order to prevent damage to the decorative surface during stacking and handling, the decorative surfaces of every two boards 100 are placed opposite to each other, that is, the orientations of the decorative surfaces of every two adjacent boards 100 are opposite. Therefore, in the production process, before the board 100 is decorated by pasting the decorative material 200, and before the board 100 is discharged after pasting and pressing, the board 100 needs to be turned over at intervals. Before the board 100 is pasted with the decorative material 200, the decorative surface of the board 100 needs to be turned over to face upwards, and before the board 100 is discharged, the board 100 needs to be turned over to have the decorative surface facing in the opposite direction to that of the adjacent board 100. In this embodiment, the decorative board 100 production system further comprises a first board turning device 91 connected to the control center signal, which is located before the coating unit 3 and is used to turn over the decorative surface of the board 100 to be decorated to face upwards.

[0229] For example, the first board turning device 91 can be located before the board cutting unit 60 and is used to turn over the decorative surface of the board 100 to face upwards before the board 100 is cut. Alternatively, the first board turning device 91 is located between the board cutting unit 60 and the paint spraying unit 2 and is used to turn over the decorative surface of the board 100 to face upwards before the board 100 is sprayed with paint. Alternatively, referring to Figure 1-2 , the first board turning device 91 is located between the paint spraying unit 2 and the coating unit 3 and is used to turn over the decorative surface of the board 100 to face upwards before the board 100 is coated with the decorative material 100.

[0230] Correspondingly, the decorative board 100 production system further comprises a second board turning device 92 connected to the control center signal, which is located to turn over the board 100 after decoration to have the decorative surface facing in the opposite direction to that of the adjacent board 100 after decoration, so that the decorative surfaces of every two boards 100 are placed opposite to each other when stacking. For example, referring to Figure 1-3 , the second board turning device 92 is located after the film pasting unit 80 and is used to turn over the board 100 after pasting the film to have the decorative surface facing in the opposite direction to that of the adjacent board 100 after decoration.

[0231] In actual production, after the plate material 100 is cut to the set size by the plate material cutting unit, the cutting surface of the cut plate material 100 is adhered with stains and dust. In order to avoid quality problems such as bulging when the subsequent coating unit applies the decorative surface with the decorative material 200, the cutting surface of the plate material 100 needs to be cleaned. The decorative plate material 100 production system of the embodiment is provided with a cleaning device (not shown in the figure) between the plate material cutting unit 60 and the paint spraying unit, to clean the cutting surface of the plate material 100.
