[0031] Refer to Figure 1 、 2, as shown in FIGS. 3 and 4, the profiling laminating machine according to the embodiment of the present utility model includes a frame 100, a laminating assembly and a pressing block 600 mounted on the frame 100. The laminating assembly includes a first pressing head 200 for pressing the edge band 2000 onto the lower vertical surface 1002, a second pressing head 300 for pressing the edge band 2000 onto the flat surface 1003, a third pressing head 400 for pressing the edge band 2000 onto the lower arc surface 1004, and a fourth pressing head 500 for pressing the edge band 2000 onto the upper arc surface 1005. Both the third pressing head 400 and the fourth pressing head 500 are provided in plurality, and both the third pressing head 400 and the fourth pressing head 500 are rotatably and horizontally movably mounted on the frame 100; as Figure 1 , 2 shown, a pressing block 600 is fixedly connected to the top of at least one third pressing head 400, and a pressing block 600 is fixedly connected to the top of at least one fourth pressing head 500. At least a part of the pressing block 600 protrudes towards the profiled plate 1000 (to the right) and protrudes outside the third pressing head 400 or the fourth pressing head 500, as Figure 4 shown, so that when the pressing block 600 moves with the third pressing head 400 or the fourth pressing head 500, the edge band 2000 can be folded onto the upper end surface of the profiled plate 1000.

[0032] As Figure 2 , 4 shown, pressing blocks 600 are provided on the tops of both the third pressing head 400 and the fourth pressing head 500. When the third pressing head 400 moves into the notch 1001 of the profiled plate 1000 or the fourth pressing head 500 moves into the notch 1001 of the profiled plate 1000, the pressing block 600 also moves with the third pressing head 400 or the fourth pressing head 500. Furthermore, the pressing block 600 can fold the edge band 2000 onto the upper end surface of the profiled plate 1000, so that the pressing block 600 blocks the leftward movement of the edge band 2000 above the pressing head 400, ensuring that the lower vertical surface 1006 can be normally laminated; and since both the third pressing head 400 and the fourth pressing head 500 are rotatable, when the third pressing head 400 rotates to laminate the lower arc surface 1004 or the fourth pressing head 500 rotates to laminate the upper arc surface 1005, the pressing block 600 also rotates with the third pressing head 400 or the fourth pressing head 500. Furthermore, the excess edge band 2000 above the upper vertical surface 1006 is straightened under the frictional force of the rotation of the pressing block 600, making the edge band 2000 not easily folded, thereby improving the quality of the board lamination.

[0033] Specifically, the shape of the profiled plate 1000 is as Figure 3 and 5As shown, the left side wall of the special-shaped plate 1000 has a notch 1001. The notch 1001 is recessed in the rightward direction, and its bottom is arc-shaped. The notch 1001 includes a first notch segment 10011 and a second notch segment 10012. The first notch segment 10011 is located on the front side of the second notch segment 10012. The distance between the bottom of the first notch segment 10011 and the left side surface of the special-shaped plate 1000 gradually decreases from the rear to the front. The second notch segment 10012 extends in the front-rear direction. The notch 1001 includes a lower vertical surface 10013 and an upper vertical surface 10014. The upper vertical surface 10014 is located on the right side of the lower vertical surface 10013, making the notch 1001 in a J shape. The notch 1001 successively includes a lower vertical surface 1002, a flat straight surface 1003, a lower arc surface 1004, an upper arc surface 1005, and an upper vertical surface 1006 from bottom to top. The upper vertical surface 1006 includes an arc segment 1007 and a vertical segment 1008. The upper vertical surface 1006 is located on the right side of the lower vertical surface 1002;

[0034] During operation, as Figure 5 shown, a sealing strip 2000 is pre-pasted on the lower vertical surface 1002 of the special-shaped plate 1000. The special-shaped plate 1000 is located on the right side of the profiling laminating machine. As Figure 1 、 5 shown, the special-shaped plate 1000 is conveyed from front to back by a conveying device. During the conveying process, the second pressing head 300, the third pressing head 400, and the fourth pressing head 500 move to the right in sequence. The first pressing head 200 does not need to move and directly performs further lamination on the lower vertical surface 1002. The second pressing head 300 moves to the right to laminate the sealing strip 2000 on the flat straight surface 1003. As Figure 1 、 4As shown in the figure, the third pressing head 400 moves to the right and moves into the notch 1001. At the same time, the pressing block 600 on the third pressing head 400 moves with the third pressing head 400, so that the third pressing head 400 presses the edge band 2000 onto the lower arc surface 1004, and the pressing block 600 folds the edge band 2000 above the upper vertical surface 1006 onto the upper end surface of the special-shaped plate 1000. During the movement of the special-shaped plate 1000, the special-shaped plate 1000 drives the third pressing head 400 and the pressing block 600 to rotate. Under the action of the rotating third pressing head 400 and the rotating pressing block 600, the edge band 2000 located above the upper vertical surface 1006 is straightened, avoiding the situation of the edge band 2000 being folded. Then the fourth pressing head 500 moves to the right to press the edge band 2000 onto the upper arc surface 1005. The fourth pressing head 500 and the pressing block 600 of the fourth pressing head 500 also rotate with the movement of the special-shaped plate 1000, pressing the edge band 2000 onto the upper arc surface 1005 and making the edge band 2000 not folded. Among them, under the folding action of the pressing block 600, the edge band 2000 has been partially pasted on the upper vertical surface 1006. The pressing of the upper vertical surface 1006 can be carried out by other machines, or a fifth pressing head for pressing the upper vertical surface 1006 is provided behind the fourth pressing head 500.

[0035] Specifically, as Figure 1 shown, when there are multiple third pressing heads 400 and fourth pressing heads 500, some of the third pressing heads 400 are provided with pressing blocks 600, and some of the fourth pressing heads 500 are provided with pressing blocks 600; for example, there are four third pressing heads 400 and three fourth pressing heads 500. The second pressing head 300, the four third pressing heads 400 and the three fourth pressing heads 500 are arranged in sequence along the front-back direction. One of the third pressing heads 400 located at the forefront is not provided with a pressing block 600, and each of the other three third pressing heads 400 is respectively provided with a pressing block 600. One of the fourth pressing heads 500 located at the forefront is provided with a pressing block 600, and the other two fourth pressing heads 500 are not provided with pressing blocks 600. With this setting, the pressing block 600 is fully utilized, the manufacturing cost of the profiling laminating machine is reduced, and the structure of the profiling laminating machine is simple.

[0036] Specifically, as Figure 6 shown, at least a part of the right side surface of the first pressing head 200 is a plane, which is convenient for pressing the edge band 2000 onto the lower vertical surface 1002 of the special-shaped plate 1000.

[0037] Specifically, as Figure 4 shown, the lower end surface of the second pressing head 300 is a plane, which is convenient for pressing the edge band 2000 onto the flat straight surface 1003 of the special-shaped plate 1000.

[0038] Specifically, as Figure 1As shown, the pressing block 600 is disc-shaped, and it uniformly folds the edge band 2000 onto the upper end surface of the special-shaped plate 1000; or the pressing block 600 is strip-shaped. For example, the pressing block 600 is a steel wire. When the pressing block 600 rotates, it folds the edge band 2000 onto the upper end surface of the special-shaped plate 1000 and straightens the edge band 2000 so that the edge band 2000 is not folded.

[0039] In some embodiments of the present utility model, as Figure 2 , 4 shown, both the third pressing head 400 and the fourth pressing head 500 are pressing wheels. The shape of the outer side wall 401 of the pressing wheel matches the shapes of the upper arc surface 1005 and the lower arc surface 1004 on the special-shaped plate 1000, so that the third pressing head 400 and the fourth pressing head 500 can share one part, reducing the manufacturing cost of the laminating machine.

[0040] In a further embodiment of the present utility model, as Figure 2 , 4 shown, the top of the pressing wheel has a boss 410 that can press against the vertical surface 1006 on the special-shaped plate 1000. The pressing block 600 is installed on the top of the boss 410, so that when the pressing wheel presses the edge band 2000 against the upper arc surface 1005 or the lower arc surface 1004, it can simultaneously press the edge band 2000 against the upper vertical surface 1006 and fold it onto the upper end surface of the special-shaped plate 1000.

[0041] In a further embodiment of the present utility model, as Figure 4 shown, the lower end surface of the pressing wheel is a plane, so that the pressing wheel can press against the upper arc surface 1005 and the lower arc surface 1004, and can also press against the flat straight surface 1003.

[0042] In some embodiments of the present utility model, as Figure 6 shown, the laminating assembly further includes a first driving device 700, a second driving device 800, and a third driving device 900. The first driving device 700, the second driving device 800, and the third driving device 900 are arranged in sequence along the conveying direction of the special-shaped plate 1000. The first driving device 700 is connected to the second pressing head 300, and the first driving device 700 is used to drive the second pressing head 300 to move left and right. The second driving device 800 is connected to one third pressing head 400, and the second driving device 800 is used to drive the third pressing head 400 to move left and right. The third driving device 900 is connected to one fourth pressing head 500, and the third driving device 900 is used to drive the fourth pressing head 500 to move left and right. The first pressing head 200 is located below the second pressing head 300. By means of the first driving device 700, the second driving device 800, and the third driving device 900, the second pressing head 300, the third pressing head 400, and the fourth pressing head 500 can automatically move to the right in sequence, and automatically press the edge band 2000 into the notch 1001 of the special-shaped plate 1000.

[0043] Specifically, the first driving device 700, the second driving device 800, and the third driving device 900 are all first cylinders.

[0044] In a further embodiment of the present invention, as Figure 7 shown, as Figure 6 shown, it further includes a first bracket 110. The first driving device 700, the second driving device 800, and the third driving device 900 are all installed on the first bracket 110 so as to be movable up and down.

[0045] Specifically, the first bracket 110 is installed with three second cylinders 111, and the extending rods of the three second cylinders 111 are respectively connected to the first driving device 700, the second driving device 800, and the third driving device 900.

[0046] In a further embodiment of the present invention, as Figure 6 , 7 shown, it further includes a second bracket 120. The second bracket 120 is installed on the frame 100 so as to be slidable up and down. The frame 100 is installed with a fourth driving device 130 for driving the second bracket 120 to move up and down. The first bracket 110 is installed on the second bracket 120 so as to be movable left and right. The second bracket 120 is provided with a fifth driving device 121 for driving the first bracket 110 to move left and right. The first pressing head 200 is installed on the first bracket 110.

[0047] The second bracket 120 can move up and down, and the first pressing head 200, the second pressing head 300, the third pressing head 400, and the fourth pressing head 500 are installed on the first bracket 110, and the first bracket 110 is installed on the second bracket 120, so as to roughly adjust the up and down direction positions of the first pressing head 200, the second pressing head 300, the third pressing head 400, and the fourth pressing head 500 through the fourth driving device 130; and the first bracket 110 can move left and right relative to the second bracket 120, so as to adjust the left and right direction positions of the first pressing head 200, the second pressing head 300, the third pressing head 400, and the fourth pressing head 500 through the fifth driving device 121.

[0048] In a further embodiment of the present invention, as Figure 7As shown, a plurality of guide posts 140 are arranged on the frame 100 at intervals in the left-right direction. A sliding sleeve 122 is arranged in the second bracket 120, and the sliding sleeve 122 is slidably connected to the guide posts 140, making the movement of the second bracket 120 more stable and ensuring the laminating effect.

[0049] In a further embodiment of the present utility model, as Figure 7 , 8 shown, it further includes an adjusting screw 150 and a nut 160. The adjusting screw 150 includes a head 151 and a threaded portion 152. A guide seat 170 is arranged on the frame 100. A plurality of guide rods 210 are arranged at the left end of the first pressing head 200. The plurality of guide rods 210 are slidably mounted on the guide seat 170 in the left-right direction and penetrate through the guide seat 170. The left ends of the plurality of guide rods 210 are connected to a connecting plate 220. The connecting plate 220 is located to the left of the guide seat 170. The connecting plate 220 is slidably sleeved outside the threaded portion 152. The nut 160 is located to the right of the connecting plate 220 and is threadedly connected to the threaded portion 152. The head 151 is located to the left of the connecting plate 220. A spring 230 is arranged between the head 151 and the connecting plate 220. The end of the threaded portion 152 away from the head 151 is connected to the guide seat 170.

[0050] As Figure 8 shown, when the first pressing head 200 needs to be adjusted to the left in position, drive the first pressing head 200 to move to the left, so that the connecting plate 220 moves to the left synchronously. The connecting plate 220 compresses the spring 230. The user adjusts the nut 160 to make the nut 160 move to the left. After the adjustment is completed, the nut 160 blocks the connecting plate 220 from moving to the right, thereby adjusting the position of the first pressing head 200.

[0051] Since a spring 230 is arranged to the left of the connecting plate 220, the first pressing head 200 can adapt to different-sized special-shaped plates 1000.
