[0034] Refer to Figure 1 、 2 As shown in FIGS. Figure 3 、 4 The arc surface pressing device according to the first embodiment of the present utility model includes a conveying structure 100 for moving a plate 800 back and forth, and a milling groove structure 200, an adhesive coating structure 300, a first pressing structure 400, a cutting structure 500, a heating structure 600, and a second pressing structure 700 that are sequentially arranged along the conveying direction (front-back direction) of the plate 800 and are provided on the left side of the conveying structure 100; as Figure 5 shown, the milling groove structure 200 is used for milling the left semi-circular arc surface 801 of the plate 800 so that the left side of the plate 800 has a semi-circular arc notch 810 protruding upward; as Figure 6 shown, the adhesive coating structure 300 is used for applying glue to the edge band 900 and pressing the bottom of the edge band 900 onto the semi-circular arc notch 810; as Figure 7 、 8 shown, the first pressing structure 400 includes a first pressing head 410, and the right side of the first pressing head 410 has a pressing surface 411 that matches the shape of the semi-circular arc surface 801, and the pressing surface 411 is also in a semi-circular arc shape. The first pressing head 410 presses the edge band 900 onto the semi-circular arc notch 810 through the pressing surface 411; as Figure 1 、 2 shown, the cutting structure 500 includes a rotatable cutting knife 510, and the cutting knife 510 is used for cutting off the part of the edge band 900 located outside the semi-circular arc notch 810; as Figure 9 shown, the heating structure 600 is used for heating the edge band 900 located on the semi-circular arc notch 810; as

[0035] As Figure 9As shown in the figure, a semi-circular notch 810 with a depression depth equal to the thickness of the edge band 900 is milled on the semi-circular surface 801 on the left side of the plate 800 through the milling groove structure 200. When the edge band 900 is attached to the semi-circular notch 810, there will be no unevenness between the edge band 900 and the upper end surface 802 of the plate 800. And by arranging a cutting structure 500, a heating structure 600 and a second pressing structure 700 after the first pressing structure 400, after the edge band 900 is preliminarily pressed on the semi-circular notch 810 and the upper end surface 802 of the plate 800, the cutting structure 500 can cut off the part of the edge band 900 outside the semi-circular notch 810, so that the edge band 900 can completely cover the semi-circular notch 810, and the edge of the edge band 900 will not warp to cause unevenness. In addition, the heating structure 600 can reheat the glue on the edge band 900, and cooperate with the secondary pressing of the second pressing structure 700, so as to make the edge band 900 completely adhere to the semi-circular notch 810. By arranging the cutting structure 500, the heating structure 600 and the second pressing structure 700, the excess part of the edge band 900 can be accurately cut off, so that the edge band 900 is accurately attached to the semi-circular notch 810, the edge band 900 will not warp to cause unevenness, and the edge band 900 is similar to the plate 800 to form an integral structure. Because the edge band 900 is embedded in the semi-circular notch 810, the appearance is more beautiful.

[0036] As Figure 1 shown, during operation, the plate 800 is conveyed by the conveying structure 100 and passes through the milling groove structure 200, the glue coating structure 300, the first pressing structure 400, the cutting structure 500, the heating structure 600 and the second pressing structure 700 in sequence;

[0037] When the plate 800 passes through the milling groove structure 200, the milling groove structure 200 performs milling on the semi-circular surface 801 on the left side of the plate 800. As Figure 4 shown, the left side of the plate 800 has a semi-circular notch 810 protruding upwards, and the depression depth of the semi-circular notch 810 is the same as the thickness of the edge band 900;

[0038] When the plate 800 passes through the glue coating structure 300, as Figure 5 shown, the glue coating structure 300 applies glue to the edge band 900 and presses the bottom of the edge band 900 against the semi-circular notch 810;

[0039] As Figure 8 shown, since the width of the edge band 900 is relatively long, when the plate 800 passes through the first pressing structure 400, the first pressing head 410 can preliminarily press the edge band 900 against the semi-circular notch 810 and the upper end surface 802 of the plate 800 through the pressing surface 411. The part of the edge band 900 located on the upper end surface 802 of the plate 800 is the excess part;

[0040] As Figure 8 , 9 shown, when the sheet 800 passes through the cutting structure 500, the cutting structure 500 can cut off the above-mentioned extra part. Among them, a part of the edge band 900 may also be located below the lower end surface of the sheet 800, and the cutting structure 500 can also cut off this part, or it can be cut off by other structures;

[0041] When the sheet 800 passes through the heating structure 600, the heating structure 600 heats the edge band 900 located on the semi-circular notch 810, melting the glue on the edge band 900, which facilitates pressing the edge band 900 onto the semi-circular notch 810 again;

[0042] When the sheet 800 passes through the second pressing structure 700, as Figure 8 shown, since the extra part is located above the upper end surface 802 of the sheet 800, this part will cause a part of the edge band 900 not to be attached to the semi-circular notch 810. As Figure 9 shown, so the second pressing structure 700 presses the edge band 900 onto the semi-circular notch 810 again.

[0043] Specifically, the milling groove structure 200 includes a frame, a motor and a milling cutter capable of milling a semi-circle. The milling cutter is connected to the rotating shaft of the motor, and the motor is installed on the frame so as to be movable up and down and movable left and right. During operation, the milling cutter moves up and down and left and right to mill a notch on the semi-circular surface 801 of the sheet 800; the conveying structure 100 is used to clamp the upper and lower ends of the sheet 800 and drive it to move. The conveying structure 100 can adopt two clamping members symmetrically arranged in the up and down directions. The clamping members can be driven to move along the conveying direction of the sheet 800. The clamping members can be cylinders or other structures capable of clamping and moving, or the conveying structure 100 adopts two rollers spaced up and down. The sheet 800 is arranged between the two rollers, and the rotation of the two rollers drives the sheet 800 to move along the conveying direction; the gluing structure 300 can adopt existing gluing equipment.

[0044] In some embodiments of the present invention, as Figure 6 shown, the first pressing structure 400 further includes a second pressing head 420. The first pressing heads 410 are provided in several numbers. The second pressing head 420 and several first pressing heads 410 are arranged in sequence along the conveying direction of the sheet 800. When the sheet 800 moves, the second pressing head 420 can gradually guide the edge band 900 to the semi-circular notch 810, and the first pressing heads 410 can press the edge band 900 onto the semi-circular notch 810.

[0045] By providing a second pressing head 420 to gradually press the edge band 900 against the semi-circular notch 810, it facilitates the subsequent pressing by the first pressing head 410, resulting in a better pressing effect. Also, by providing a plurality of first pressing heads 410, through the pressing of the plurality of first pressing heads 410, the edge band 900 can be more firmly attached to the semi-circular notch 810.

[0046] Specifically, the second pressing head 420 is a bent rod, and the distance between the rod and the plate 800 gradually increases along the conveying direction of the plate 800. Thus, when the plate 800 moves, the edge band 900 on the plate 800 is gradually attached to the semi-circular notch 810 under the action of the bent rod, facilitating the subsequent pressing by the first pressing head 410. That is, the second pressing head 420 serves to guide the edge band 900 to be attached to the semi-circular notch 810, and the second pressing head 420 does not press the edge band 900 against the semi-circular notch 810. The first pressing head 410 is needed to further press the edge band 900 against the semi-circular notch 810.

[0047] In a further embodiment of the present utility model, as Figure 6 shown, the first pressing structure 400 further includes a first mounting frame 430, a first sliding seat 440, and a first driving device 450. The first sliding seat 440 is movably mounted on the first mounting frame 430 in the up and down direction. The first pressing head 410 and the second pressing head 420 are both mounted on the first sliding seat 440. The first driving device 450 is mounted on the first mounting frame 430, and the first driving device 450 is used to drive the first sliding seat 440 to move up and down. The first sliding seat 440 can move up and down, enabling the second pressing head 420 and the first pressing head 410 to adapt to plates 800 of different thicknesses.

[0048] Specifically, the first driving device 450 can be a cylinder; the first sliding seat 440 is slidably connected to the first mounting frame 430 through a slider and a slide rail.

[0049] In some embodiments of the present utility model, as Figure 7As shown, the cutting structure 500 further includes a first cutting assembly 520. The first cutting assembly 520 includes a sliding base 521, a second sliding seat 522, a second driving device 523, a third driving device 524, a first positioning member 525 and a second positioning member 526. The second sliding seat 522 is movably mounted on the sliding base 521 in the left-right direction. The second driving device 523 is mounted on the sliding base 521, and the second driving device 523 is used to drive the second sliding seat 522 to move left and right. The third driving device 524, the first positioning member 525 and the second positioning member 526 are all mounted on the second sliding seat 522. The third driving device 524 is connected to the cutting tool 510, and the third driving device 524 is used to drive the cutting tool 510 to rotate. The second positioning member 526, the cutting tool 510 and the first positioning member 525 are arranged at intervals in the left-right direction of the second sliding seat 522. The second positioning member 526 is located below the first positioning member 525. The first positioning member 525 can abut against the upper end surface 802 of the plate 800, and the second positioning member 526 can abut against the left side of the plate 800.

[0050] By providing the first positioning member 525 to abut against the upper end surface 802 of the plate 800, the positioning of the cutting tool 510 in the up-down direction is realized. By providing the second positioning member 526 to abut against the left side of the plate 800, the positioning of the cutting tool 510 in the left-right direction is realized, so that the cutting tool 510 can accurately cut off the part of the edge band 900 located outside the semi-circular notch 810.

[0051] When the plate 800 is moved to below the first positioning member 525, the first positioning member 525 abuts against the upper end surface 802 of the plate 800 to realize the positioning of the cutting tool 510 in the up-down direction. The second driving device 523 drives the second sliding seat 522 to move rightward relative to the sliding base 521, so that the second positioning member 526 abuts against the left side of the plate 800 to realize the positioning of the cutting tool 510 in the left-right direction. The third driving device 524 drives the cutting tool 510 to rotate. As Figure 8 shown, during the movement of the plate 800, the cutting tool 510 accurately cuts off the part of the edge band 900 located outside the semi-circular notch 810.

[0052] Specifically, the sliding base 521 can move up and down to adapt to plates 800 of different sizes.

[0053] In a further embodiment of the present invention, as Figure 7 、 8As shown, the cutting knife 510 is a saw blade. The axis of the saw blade is parallel to the left-right direction of the second sliding seat 522. The semi-circular notch 810 has a vertical wall 811. The cutting edge of the saw blade is aligned with the vertical wall 811. By aligning the cutting edge of the saw blade with the vertical wall 811, during the movement of the plate 800, the saw blade can accurately cut off the excess part of the edge band 900 located on the upper end surface 802 of the plate 800 along a straight line, ensuring that the edge band 900 can be accurately attached to the semi-circular notch 810, and the edge band 900 will not warp at the vertical wall 811, resulting in unevenness.

[0054] In some embodiments of the present invention, as Figure 10 , 11 shown, the semi-circular notch 810 has a vertical wall 811. The second pressing structure 700 includes a second mounting frame 710 and a plurality of pressing structures 720 arranged in sequence along the conveying direction of the plate 800. The pressing structure 720 includes a cylinder 721, a first moving frame 722, a second moving frame 723, and a pressing wheel 724. The cylinder 721 is mounted on the second mounting frame 710. The first moving frame 722 is connected to the extending end of the cylinder 721. The cylinder 721 is used to drive the first moving frame 722 to move up and down. The second moving frame 723 is movably mounted on the first moving frame 722 in a left-right direction. An adjusting structure 725 for driving the second moving frame 723 to move left and right is mounted on the first moving frame 722. The pressing wheel 724 is rotatably mounted on the second moving frame 723. The pressing wheel 724 is located above the vertical wall 811. The axis of the pressing wheel 724 is parallel to the left-right direction of the second mounting frame 710;

[0055] As Figure 8 , 9 shown, when the first pressing structure 400 presses, a part of the edge band 900 is located above the upper end surface 802 of the plate 800. The edge band 900 located at the vertical wall 811 is not attached to the semi-circular notch 810 under the support of the upper end surface 802 of the plate 800. By providing a pressing wheel 724 that can move up and down, and the position of the pressing wheel 724 corresponds to the position of the vertical wall 811, so that the pressing wheel 724 can press the edge band 900 located at the vertical wall 811 onto the semi-circular notch 810.

[0056] As Figure 9 , 10 , 11 shown, during operation, the plate 800 moves to the lower side of the pressing wheel 724. The cylinder 721 drives the first moving frame 722 to move downward. Then, the first moving frame 722 drives the pressing wheel 724 on the second moving frame 723 to move downward. The pressing wheel 724 presses the edge band 900 located at the vertical wall 811 onto the semi-circular notch 810.

[0057] The adjusting structure 725 can drive the second moving frame 723 to move left and right relative to the first moving frame 722, so as to adjust the position of the pressing wheel 724 in the left and right directions, and make the pressing wheel 724 adapt to plates 800 of different sizes.

[0058] Specifically, the adjusting structure 725 includes a screw rod and a nut. One end of the screw rod is rotatably installed on the first moving frame 722, the nut is installed on the second moving frame 723, and the other end of the screw rod is in threaded connection with the nut. When it is necessary to adjust the position of the pressing wheel 724 in the left and right directions, the screw rod is rotated, and the screw rod drives the second moving frame 723 to move left and right, thereby adjusting the position of the pressing wheel 724 in the left and right directions.

[0059] In some embodiments of the present invention, as Figure 2 , 12 shown, a trimming mechanism 1000 is provided between the first pressing structure 400 and the cutting structure 500.
