[0046] The technical solution provided by this application may include the following beneficial effects:

[0047] The edge banding machine provided by this application has optimized the design of the structures of the trimming mechanism, the tracking mechanism, and the edge scraping mechanism. Firstly, the unused space on the frame of the edge banding machine is effectively utilized.

Secondly, the edge scraping mechanism has flexible installation and can move freely on the guide rail and the pressing beam, occupying less installation space compared to the existing edge scraping mechanism, effectively improving the space utilization rate, helping to reduce the overall length of the edge banding machine, and meeting the usage requirements of a small-sized edge banding machine. Finally, the upper trimming assembly and the lower trimming assembly of the trimming mechanism are located on the same side and are horizontally arranged, being more compact in structure compared to the existing trimming mechanism, realizing the miniaturization of the trimming mechanism and the overall dimensions of the machine, and meeting the application occasions with a small space.

[0048] Compared with the prior art, the edge scraping mechanism of this solution is arranged on the pressure beam and guide rail of the frame in a suspended manner, creating installation space for the tracking mechanism. Moreover, one tracking motor is used to track and trim the four corners of the plate. Structurally, it cooperates with the horizontal movement component, vertical movement component, and guiding component to achieve multi-directional adjustment, ensuring that the tracking cutter can always be in contact with the plate to achieve fillet processing, which has relatively prominent beneficial effects.

In the description of the present application, "a plurality" means two or more unless otherwise specifically defined.

[0097] The technical solutions of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0098] See Figure 1 , Figure 1 which is a schematic structural diagram of an edge banding machine shown in the embodiments of the present application.

[0099] An edge banding machine provided by the present application includes a frame 1;

[0100] A conveying mechanism 2 is arranged on the frame 1, and a pre-milling mechanism 3, a gluing mechanism 4, a tape feeding mechanism 5, a pressing mechanism 6, a trimming mechanism 7, a trimming mechanism 8, a tracking mechanism 9, a scraping mechanism 10, a flexible flat scraping mechanism 11 and a polishing mechanism 12 are sequentially arranged along the conveying direction of the conveying mechanism 2;

[0101] The trimming mechanism 8 includes an upper trimming assembly 800 and a lower trimming assembly 801 which are arranged on the same side and connected to each other. Both the upper trimming assembly 800 and the lower trimming assembly 801 have a trimming motor 802 arranged horizontally, and a trimming knife 803 is connected to the motor shaft of the trimming motor 802;

[0102] The tracking mechanism 9 includes a horizontal movement component 900, a vertical movement component 901, a tracking component 902, and a guiding component 903. The horizontal movement component 900 is used to drive the tracking component 902 to move horizontally. The vertical movement component 901 is used to drive the tracking component 902 and the guiding component 903 to move vertically. The tracking component 902 has a tracking motor 904. The guiding component 903 is used to position and guide the board so that the tracking component 902 moves synchronously along the side of the board.

[0103] The edge scraping mechanism 10 includes an upper edge scraping component 1000 slidably arranged on the pressing beam 17 of the machine frame 1 and a lower edge scraping component 1001 slidably arranged on the guide rail 18 of the machine frame 1. An installation station for the horizontal movement component 900 is formed between the lower edge scraping component 1001 and the machine frame 1.

[0104] Specifically, the pre-milling mechanism 3, the tape feeding mechanism 5, the glue coating mechanism 4, the pressing and pasting mechanism 6, the trimming mechanism 7, the edge trimming mechanism 8, the tracking mechanism 9, the edge scraping mechanism 10, the flexible flat edge scraping mechanism 11, the polishing mechanism 12, and the conveying motor are sequentially installed on the edge banding machine frame 1 along the advancing direction of the conveying mechanism 2. The conveying motor is connected to the conveying mechanism 2 and is used to provide power to the conveying mechanism 2.

[0105] Among them, the pre-milling mechanism 3 is used to perform pre-milling on the edges of the board to be edge banded, which can eliminate the adverse effects such as the broken edges of the board caused by poor sawing and improve the edge banding quality. The tape feeding mechanism 5, the glue coating mechanism 4, and the pressing and pasting mechanism 6 together form a set of glue coating components for applying EVA glue. The glue coating mechanism 4 can apply EVA glue, and has the function of automatically cleaning the adhesive agglomeration blockage on the edge of the glue door to realize glue pot cleaning, which can improve product quality and processing efficiency.

[0106] The tape feeding mechanism 5 can automatically cut the edge banding tape according to the length of the board and convey the edge banding tape to the board to be edge banded. The pressing and pasting mechanism 6 is used to press the edge banding tape conveyed by the tape feeding mechanism 5 onto the board. After the board is coated with glue, the edge banding tapes on both sides of the board are slightly longer than the board. The trimming mechanism 7 is used to trim the excess edge banding tapes on both sides of the board.

[0107] The edge trimming mechanism 8 is used to finely trim the upper and lower edges of the edge banded board.

[0108] The tracking mechanism 9 is used to trim the four right angles of the edges of the edge banded board into arc angles.

[0109] The edge scraping mechanism 10 is used to scrape the upper and lower edges of the edge banded board to eliminate the trimming ripples on the edge banding tape after trimming.

[0110] The flexible flat scraping edge mechanism 11 is used to clean the residual glue on the upper and lower surfaces of the board after edge banding, and adopts a flexible positioning structure. The tool can form an adaptive flat scraping edge according to the actual situation of the upper and lower surfaces of the board, avoiding the situation that the tool scratches the board when the surface of the board is uneven.

[0111] The polishing mechanism 12 is used to remove the burrs on the edge of the edge banding and the residual glue between the edge banding and the wooden board, making the edge of the wooden board more clean and smooth.

[0112] It can be understood that the pre-milling mechanism 3, the glue coating mechanism 4, the tape feeding mechanism 5, the trimming mechanism 7 and the flexible flat scraping edge mechanism 11 are all existing technologies, so they will not be described in detail one by one here.

[0113] For the edge banding machine provided by the present application, the structures of the trimming mechanism 8, the tracking mechanism 9 and the scraping edge mechanism 10 are optimized. Firstly, the unused space on the frame 1 of the edge banding machine is effectively utilized. Without mutual interference, the horizontal moving component 900 of the tracking mechanism 9 is arranged under the scraping edge mechanism 10, improving the utilization rate of the frame 1. Secondly, the scraping edge mechanism 10 has flexible installation and can move freely on the guide rail 18 and the pressure beam 17, occupying less installation space compared with the existing scraping edge mechanism 10, effectively improving the space utilization rate, helping to reduce the overall length of the edge banding machine, and meeting the usage requirements of small-sized edge banding machines. Finally, the upper trimming component 800 and the lower trimming component 801 of the trimming mechanism 8 are located on the same side and are horizontally arranged, being more compact in structure compared with the existing trimming mechanism 8, realizing the miniaturization of the trimming mechanism 8 and the overall dimensions of the machine, and meeting the application occasions with small space.

[0114] Compared with the existing technology, the scraping edge mechanism 10 of the present solution is arranged on the pressure beam 17 and the guide rail 18 of the frame 1 in a suspended manner, leaving installation space for the tracking mechanism 9, and a tracking motor 904 is used to perform tracking trimming on the four corners of the board. Structurally, it cooperates with the horizontal moving component 900, the vertical moving component 901 and the guiding component 903 to realize multi-directional adjustment, ensuring that the tracking tool 915 can always contact the board to achieve fillet processing, and having relatively prominent beneficial effects.

[0115] Compared with the traditional edge banding machine with the same function, the overall volume of the present solution is reduced by nearly 25%, and it can be applied to more working scenarios.

[0116] In a preferred embodiment, please refer to Figures 1 to 4 , on the above-mentioned frame 1 and on one side of the polishing mechanism 12, there is a pressure material mounting plate 13. The pressure material mounting plate 13 is provided with a number of pressure wheels 14 arranged side by side. The discharging end of the conveying mechanism 2 is provided with a discharging plate 15. The pressure wheels 14 are located above the junction of the discharging end and the discharging plate 15. The pressure wheels 14 are used to position and press the upper end surface of the board;

[0117] The pressing mechanism 6 includes a pressing base 600 provided on the frame 1. The pressing base 600 is horizontally provided with a pressing mounting seat 601. The pressing mounting seat 601 is slidably engaged with the pressing base 600, and the pressing mounting seat 601 is driven to move by a pressing cylinder 602. Along the conveying direction, the pressing base 600 is provided with a main pressing wheel 603 and two taper pressing wheels 604 side by side. The main pressing wheel 603 and the two taper pressing wheels 604 move in the same direction and are slidably engaged with the pressing mounting seat 601. The main pressing wheel 603 and the two taper pressing wheels 604 are respectively driven to move by pressing wheel cylinders 605.

[0118] As Figure 5 shown, in the pressing mechanism 6 of the present application, a three-wheel pressing method is adopted to press the edge band adhered to the board. The pressing cylinder 602 is used to control the working state of the pressing mechanism 6. When the pressing mechanism 6 is on standby, the output shaft of the pressing cylinder 602 contracts. At this time, the pressing mounting seat 601 moves away from the board. When the pressing mechanism 6 is running, the output shaft of the pressing cylinder 602 advances, and the pressing mounting seat 601 approaches the board. The three pressing wheel cylinders 605 independently control the main pressing wheel 603 and the two taper pressing wheels to press the edge band on the board.

[0119] In practical applications, the edge banding machine uses a conveying motor to connect to a sprocket and drive the chain block 16 to realize the conveying of the board. The chain block 16 gradually rotates and moves downward around the axis of the sprocket. Coupled with the length limitation of the pressing beam 17 of the edge banding machine, the positioning of the upper and lower end faces of the short board is insufficient, and the corners of the board are easily knocked against the discharge plate 15. Therefore, to solve this problem, a pressing material mounting plate 13 is provided on the pressing beam 17 and at this junction. The pressing wheel 14 is connected to the pressing material mounting plate 13 through a rotating shaft. The pressing wheel 14 is arranged at the discharge end of the edge banding machine. Through the pressing wheel 14, the positioning ability of the discharge end of the edge banding machine for the end face of the board can be enhanced, and the discharge plate 15 can be effectively prevented from knocking against the board.

[0120] In a preferred embodiment, please refer to Figures 6 to 12 , the above trimming mechanism 8 further includes a vertical frame 804. The vertical frame 804 is provided with a first sliding shaft group 805 and a second sliding shaft group 806 that are parallel to each other. The bottom end face of the first sliding shaft group 805 and the top end face of the second sliding shaft group 806 are located on the same horizontal plane. The upper trimming assembly 800 is slidably connected to the vertical frame 804 through the first sliding shaft group 805, and the lower trimming assembly 801 is slidably connected to the vertical frame 804 through the second sliding shaft group 806;

[0122] The trimming slide block 807 is penetrated by a first slide shaft group 805. A linear bearing 812 perpendicular to the first slide shaft group 805 is provided on the trimming slide block 807. The trimming adjustment seat 808 is slidably connected to the trimming slide block 807 through the linear bearing 812. The motor mounting plate 809 is arranged on the trimming adjustment seat 808. The trimming motor 802 is mounted on the motor mounting plate 809. The lateral adjustment unit 811 is arranged at the bottom of the trimming motor 802. The first positioning unit 810 is arranged on the side surface of the trimming adjustment seat 808. A fine trimming station for trimming the plate is formed between the first positioning unit 810 and the lateral adjustment unit 811. The trimming knife 803 is located at the fine trimming station; the reference surface of the first positioning unit 810 and the end surface of the plate are in the same horizontal plane;

[0123] The lateral adjustment unit 811 is used to adjust the distance between the side surface of the plate and the trimming knife 803;

[0124] An adjustment screw 813 abutting against the trimming adjustment seat 808 is provided on the trimming slide block 807;

[0125] A first height adjustment member 814 and a second height adjustment member 815 are further provided on the vertical frame 804. The first height adjustment member 814 is used to adjust the horizontal height of the upper trimming assembly 800. The second height adjustment member 815 is used to adjust the horizontal height of the lower trimming assembly 801.

[0126] Further, please refer to Figure 11 and in combination with Figure 9 The above-mentioned first height adjustment member 814 includes a hanging frame 816, a hanging seat 817, an adjustment rod 819 and two adjustment springs 818. The hanging frame 816 is fixedly arranged on the pressing beam 17 of the edge banding machine. The hanging seat 817 is arranged on the trimming slide block 807. The adjustment rod 819 penetrates the trimming slide block 807 and is threadedly connected to the hanging frame 816. The end of the adjustment rod 819 has a head extending outwards. The two adjustment springs 818 are sleeved on the adjustment rod 819. The two adjustment springs 818 are respectively located between the hanging frame 816 and the hanging seat 817 and between the hanging seat 817 and the head of the adjustment rod 819;

[0127] The first positioning unit 810 includes a dovetail slide block 837, a positioning slider 838, a fixed seat 839, an adjustment element and a positioning member. The positioning member has a rolling contact surface abutting against the end surface of the plate;

[0128] First dovetail grooves and second dovetail grooves are respectively provided on the two side surfaces of the dovetail slide block 837;

[0129] The positioning slider 838 is embedded in the first dovetail groove and connected to the fixed seat 839. The fixed seat 839 is connected to the trimming slide seat 807. The positioning member is embedded in the second dovetail groove, and the adjusting element is used to adjust the horizontal height of the positioning member.

[0130] Optionally, the above-mentioned vertical frame 804 includes a connecting plate 816a, a first support plate 816b, a second support plate 816c, a front support plate 816d, a rear support plate 816e, and a trimming base 816f.

[0131] Specifically, as Figure 12 shown, the trimming mechanism 8 mainly consists of an upper trimming assembly 800, a lower trimming assembly 801, and a vertical frame 804. The first slide shaft group 805 and the second slide shaft group 806 are both composed of two optical axes. The upper end of the first slide shaft group 805 is fixed to the connecting plate 816a by screws, and the lower end passes through two holes in the first support plate 816b and is fixed to the second support plate 816c by a grub screw against a flat position; the upper and lower ends of the second slide shaft group 806 are respectively fixed to the second support plate 816c and the trimming base 816f; the left and right screw holes of the first support plate 816b and the second support plate 816c correspond to the middle four holes of the front support plate 816d and the rear support plate 816e, and they are installed between the front support plate 816d and the rear support plate 816e with screws; the upper three holes of the front support plate 816d and the rear support plate 816e are fixed to the left and right three holes of the connecting plate 816a with screws, and the lower four holes are fixed to the left and right four holes of the trimming base 816f with screws. The hanging frame 816 is installed on the pressing beam 17 of the machine, so its spatial position is fixed; the adjusting rod 819 passes through the hanging seat 817 and is fixed to the hanging frame 816 by a nut. Springs are provided between the end of the adjusting rod 819 and the hanging seat 817, and between the hanging seat 817 and the hanging frame 816; by rotating the nut for fixing the adjusting rod 819, the position of the adjusting rod 819 relative to the hanging seat 817 in the vertical direction can be changed, thereby changing the position of the hanging seat 817 in the vertical direction.

[0132] In this embodiment, the trimming slide block 807 of the upper trimming assembly 800 is the upper trimming slide block 807, and the trimming slide block 807 of the lower trimming assembly 801 is the lower trimming slide block 807. The linear bearings 812 are embedded in both the upper trimming slide block 807 and the lower trimming slide block 807. The upper trimming slide block 807 can slide between the connecting plate 816a and the first support plate 816b along the first slide shaft group 805. The lower trimming slide block 807 can slide between the second support plate 816c and the trimming base 816f along the second slide shaft group 806. The four holes on the upper trimming slide block 807 are fixed to the four holes of the hanging seat 817 with screws. The upper trimming slide block 807 can move vertically up and down together with the hanging seat 817. At this time, the upper trimming assembly 800 can also move vertically up and down, so as to adjust the vertical up and down position of the upper trimming assembly 800. Since the upper and lower parts of the hanging seat 817 are supported by springs, when the upper trimming assembly 800 is pushed upward by the sheet material, the elastic force of the spring provides a downward pressure, so that the upper trimming assembly 800 has the effect of closely adhering to the sheet material.

[0133] The bottom of the lower trimming slide block 807 contacts one end of a spring of the first adjusting member (i.e., the cooperation of the spring and the bolt) on the trimming base 816f, and the other end of the spring is installed on a bolt. The spring provides a force that always pushes the lower trimming slide block 807 upward. A limiting block is installed on the side of the lower trimming slide block 807, which corresponds to a screw of the first support plate 816b and abuts against each other when the lower trimming slide block 807 moves vertically upward to limit the lower trimming slide block 807 at a reasonable working height. By adjusting the height of the bolt, the force provided by the spring for the lower trimming slide block 807 can be adjusted. Since the lower trimming assembly 801 is supported by a spring, when the lower trimming assembly 801 is pushed downward by the sheet material, the elastic force of the spring provides an upward pressure to make the lower trimming assembly 801 closely adhere to the sheet material.

[0134] In this embodiment, the structure of the upper trimming component 800 is similar to that of the lower trimming component 801. A sliding optical axis is passed through a linear bearing 812. The sliding optical axis is arranged parallel to the axis of the motor shaft. Both ends of the sliding optical axis are fixed on the baffle and the trimming adjustment seat 808. The sliding optical axis is slidably connected to the upper trimming slide 807. A screw passes through an inner hole of a spring and the baffle in sequence and then is engaged with a threaded hole of the upper trimming slide 807. The spring is compressed to generate a pressure that always pushes the upper trimming slide 807 to the left, causing it to slide horizontally to the left relative to the upper trimming slide 807. The adjusting screw 813 serves as a limiting device. After being threadedly engaged with the baffle, it passes through the baffle and abuts against the upper trimming slide 807. By turning the adjusting screw 813, the length of the front end of the screw protruding relative to the baffle can be changed to limit the distance that the baffle moves to the left. The baffle, the sliding optical axis, and the trimming adjustment seat 808 are fixed to each other. Therefore, the trimming adjustment seat 808 can be restricted to a reasonable horizontal position. Since the baffle is supported by a spring, when the upper trimming component 800 is squeezed by the sheet material and the trimming adjustment seat 808 slides to the right, the spring provides a pressure to the left to keep the upper trimming component 800 tightly attached to the sheet material. The trimming adjustment seat 808 is slidably connected to the lateral adjustment unit 811 through a guide rail 18. The lateral adjustment unit 811 includes a main connecting shaft 820, a sub-connecting shaft 821, a trimming bearing seat 822, a trimming cylinder 823, a first cushion plate 824, a first trimming adjustment shaft 825, a first locking pad 826, a second locking pad 827, a counter seat 828, a second trimming adjustment shaft 829, a third trimming adjustment shaft 830, a counter 831, a second cushion plate 832, a trimming limit block 833, a trimming slider 834, a trimming guide rail 83518, and a linear guide rail seat. Two of the sub-connecting shafts 821 and the main connecting shaft 820 are locked to the front end of the bearing structure by screws. Lateral bearings are embedded on both the main and sub-connecting shafts 821. Both the main and sub-connecting shafts 821 are eccentric shafts. When rotating this shaft, the protruding length of the edge of the lateral bearing relative to the left end edge of the trimming bearing seat 822 can be finely adjusted. It is optimal that the edges of the three lateral bearings are in the same plane. The rolling contact surface of the positioning member with the sheet material is in the same plane as the end surface of the sheet material. The trimming adjustment seat 808 and the counter seat 828 are fixedly connected by bolts. The trimming cylinder 823 and the first cushion plate 824 are connected to the tail end of the trimming bearing seat 822 by screws. The shaft of the trimming cylinder 823 is screwed into the first trimming adjustment shaft 825. The front end thread of the first trimming adjustment shaft 825 passes through the trimming bearing seat 822 and is screwed into the counter seat 828.Two trimming counters 831 are installed on the second backing plate 832, and the second backing plate 832 is fixed on the counter seat 828; the second trimming adjustment shaft 829 on the counter 831 passes through the counter seat 828 and is in threaded fit with the second locking pad 827; the third trimming adjustment shaft 830 passes through the counter seat 828 and is in threaded fit with the first locking pad 826 and the trimming bearing seat 822; both the second trimming adjustment shaft 829 and the third trimming adjustment shaft 830 can perform a certain amount of axial movement relative to the trimming counter 831; the first locking pad 826 and the second locking pad 827 are respectively fixed on the trimming bearing seat 822 and the counter seat 828, and the two locking pads play the role of tightening the thread to prevent loosening of the fit; two holes at one end of the trimming limit block 833 are connected and fixed to two holes on the counter seat 828, and the other end is on the other side of the trimming bearing seat 822 relative to the first locking pad 826, and the third trimming adjustment shaft 830 will pass through the trimming bearing seat 822 and abut against the trimming limit block 833. When the shaft of the trimming cylinder 823 extends, the trimming bearing seat 822 moves leftward along the guide rail 18 relative to the counter seat 828 until the third trimming adjustment shaft 830 abuts against the trimming limit block 833; when the shaft of the trimming cylinder 823 contracts, the trimming bearing seat 822 moves rightward along the guide rail 18 relative to the counter seat 828 until the second trimming adjustment shaft 829 abuts against the bottom surface of the trimming bearing seat 822; in this way, the trimming bearing seat 822 is driven and the movement stroke of the trimming bearing seat 822 is restricted. At the same time, in addition to driving the trimming bearing seat 822 to perform a reciprocating linear motion, the trimming cylinder 823 can also provide pressure so that the three transverse bearings fixed at the front end of the trimming bearing seat 822 always closely adhere to the plate when the mechanism is squeezed by the plate. The upper trimming motor 802 is installed on the motor mounting plate 809, and both the motor mounting plate 809 and the hinge hole device are fixed on the trimming adjustment seat 808 and move together with the trimming adjustment seat 808. The structure of the lower trimming assembly 801 is similar to that of the upper trimming assembly 800 and will not be elaborated here.

[0135] In this embodiment, the adjusting element includes a first fixing block 840, a first adjusting bolt 841, a first long machine screw 842, a second fixing block 843, a second adjusting bolt 844, a second long machine screw 845, a first adjusting seat 846, a second adjusting seat 847 and a third adjusting seat 848, and the positioning element includes a vertical bearing 849 and a bearing sleeve 850. A positioning slider 838 is fixed to the fixed seat 839 with screws. The positioning slider 838 is nested in the dovetail groove in the middle of the dovetail slide 837, and the dovetail slide 837 can slide vertically up and down along the positioning slider 838. The second adjusting bolt 844 is screwed into the threaded hole of the second fixing block 843. One end of the second long machine screw 845 passes through the round hole in the middle of the second adjusting bolt 844 and the round hole in the middle of the second fixing block 843 and is screwed into the threaded hole of the dovetail slide 837, and the other end is screwed with two nuts; among them, one nut is used to lock the second adjusting bolt 844, and the other is used to tighten the gap between the matching internal and external threads; the second fixing block 843 is fixed to the positioning slider 838 with two screws. When adjusting the up and down position of the entire dovetail slide 837, loosen the two nuts and turn the second adjusting bolt 844. When the second adjusting bolt 844 moves upward, it pushes against the two nuts to pull the second long machine screw 845 upward, and the dovetail slide 837 slides upward accordingly. When adjusted to the appropriate position, lock the two nuts again. A second adjusting seat 847 is fixedly installed in the middle of the dovetail slide 837 and can move up and down with the dovetail slide 837. The first adjusting seat 846 and the third adjusting seat 848 are embedded in the dovetail grooves on both sides of the dovetail slide 837; two first fixing blocks 840 are respectively fixed to the dovetail slide 837 with two screws. Two first adjusting bolts 841 are screwed into the first fixing blocks 840. Two first long machine screws 842 pass through the round holes in the middle of the first adjusting bolts 841 and the first fixing blocks 840 and are finally screwed into the first adjusting seat 846 and the third adjusting seat 848; the first adjusting seat 846 and the third adjusting seat 848 can move up and down with the dovetail slide 837. The up and down positions of the first adjusting seat 846 and the third adjusting seat 848 relative to the dovetail slide 837 can be adjusted in the same way by referring to the up and down position of the dovetail slide 837. Vertical bearings 849 are provided on the first adjusting seat 846, the middle second adjusting seat 847, and the third adjusting seat 848. The installation method is to press the vertical bearing 849 on the three adjusting seats through the bearing sleeve 850 and then lock it with screws.

[0136] Such as Figures 14 to 16As shown, when the mechanism operates, the board moves in the direction of the arrow, first passing through the upper trimming part and then the lower trimming part. Each of the upper and lower trimming assemblies 801 includes a hinge hole device, and the edges of the three vertical bearings 849 of the hinge hole device are all in the same plane; each of the upper and lower trimming assemblies 801 includes a bearing seat, and the edges of the three horizontal bearings fixed on the bearing seat are all in the same plane; the vertical bearings 849 and horizontal bearings of the upper and lower trimming assemblies 801 always closely adhere to the board to accurately position the trimming knives 803 of the upper trimming assembly 800 and the lower trimming assembly 801. The upper and lower ends of the edge band pasted on the board contact the trimming knives 803 of the upper trimming assembly 800 and the lower trimming assembly 801. The trimming knives 803 of the upper trimming assembly 800 and the lower trimming assembly 801 will rotate at high speed along with the motor shaft to cut off the redundant parts of the edge band above and below.

[0137] As Figure 13 shown, under normal circumstances, the three vertical bearings 849 slide closely along the surface of the board; when there are holes on the surface of the board, the bearings on the middle second adjusting seat 847 cannot press on the board, and at this time, the bearings on both sides are responsible for propping up the board until the bearings on the middle second adjusting seat 847 re-contact the board. In this way, the mechanism can always press the board tightly, preventing the problem of unstable trimming of the perforated board.

[0138] In a preferred embodiment, please refer to Figures 17 to 23 , the above-mentioned horizontal movement assembly 900 includes a base 905, a horizontal air cylinder 906 and a horizontal sliding seat 907. The base 905 is fixedly arranged on the frame 1. The horizontal sliding seat 907 is slidably connected to the base 905 through a slide rail. The horizontal air cylinder 906 is fixedly arranged on the base 905, and the output shaft of the horizontal air cylinder 906 is connected to the horizontal sliding seat 907. The horizontal sliding seat 907 is vertically provided with a first guide rod 908 and a second guide rod 909, and the guide assembly 903 passes through the second guide rod 909;

[0139] The vertical movement assembly 901 includes a vertical air cylinder 910 and a vertical sliding seat 911. The vertical sliding seat 911 passes through the first guide rod 908. The vertical air cylinder 910 is arranged on the horizontal sliding seat 907, and the output shaft of the vertical air cylinder 910 is connected to the vertical sliding seat 911;

[0140] The vertical sliding seat 911 is horizontally provided with a third guide rod 912, and the tracking assembly 902 passes through the third guide rod 912.

[0141] Furthermore, the above-mentioned tracking assembly 902 includes a four-axis sliding seat 913, a motor bracket 914, a tracking knife 915, a motor air cylinder 916, a profiling template 917, a profiling wheel 918, a fixing block 919, a tracking adjustment screw rod 920 and a scraping disc knife 921;

[0142] The four-axis slide 913 is penetrated by a third guide rod 912. A fourth guide rod is provided at the bottom of the motor support 914. The axis of the third guide rod 912 is perpendicular to the axis of the fourth guide rod. The motor support 914 is slidably connected to the four-axis slide 913 through the fourth guide rod;

[0143] The motor cylinder 916 is arranged on the four-axis slide 913. The output end of the motor cylinder 916 is connected to the motor support 914. The axis of the motor cylinder 916 is parallel to the axis of the fourth guide rod;

[0144] The profiling template 917 is arranged on one side surface of the motor support 914. The motor shaft of the tracking motor 904 is located in the circumferential direction of the profiling template 917. The profiling wheel 918 is connected to the motor shaft of the tracking motor 904;

[0145] The fixing block 919 is arranged on the side surface of the motor support 914 away from the profiling template 917. The tracking adjustment lead screw 920 penetrates the fixing block 919 and is threadedly connected to the motor support 914;

[0146] The scraping disk cutter 921 is arranged on the end surface of the profiling template 917 facing the motor support 914;

[0147] The guiding assembly 903 includes a guiding cylinder 922, a guiding slide 923 and a tracking guiding wheel 924;

[0148] The guiding slide 923 is sleeved on the second guide rod 909. The tracking guiding wheel 924 is rotatably connected to the guiding slide 923 through a rotating shaft. The axial end surface of the tracking guiding wheel 924 is parallel to the axial end surface of the tracking cutter 915;

[0149] The guiding cylinder 922 is used to drive the guiding slide 923 to move in the vertical direction.

[0150] Furthermore, the above-mentioned tracking mechanism 9 also includes an angle adjustment component, which includes an angle adjustment plate 925, a horizontal adjustment piece 926 and a vertical adjustment piece 927. The angle adjustment plate 925 is located between the motor bracket 914 and the tracking motor 904. The angle adjustment plate 925 has an arc groove 928 and two slits 929 coaxial with the motor shaft of the tracking motor 904. The two slits 929 are connected to the arc groove 928. The slit 929 and the arc groove 928 together split the angle adjustment plate 925 into an outer plate 930 and an inner plate 931, and the tracking motor 904 is arranged on the inner plate 931. The slit 929 and the arc groove 928 split the angle adjustment plate 925 into an outer plate 930 and an inner plate 931. The first end of the inner plate 931 is connected to the outer plate 930, and the second end is a free movable end. When the second end is subjected to a horizontal force, the second end can swing in the slit 929 to adjust the horizontal deflection angle of the tracking motor 904. When the second end is subjected to a vertical force, the second end can be slightly bent in the vertical direction, thereby adjusting the vertical deflection angle of the tracking motor 904. When the horizontal adjustment member 926 and the vertical adjustment member 927 are in action, the tracking knife 915 can be fine-tuned separately, eliminating the need to disassemble the tracking mechanism 9 for maintenance and adjustment. The angle adjustment plate 925 can be made of plastic material, which can take into account both tensile strength and yield strength, ensuring that it can bend when subjected to force and avoiding the risk of fracture. The slit 929 and the arc groove 928 can be constructed by water jet cutting, cutting, etc.

[0151] On the basis of the above-mentioned specific implementation, one end of the slit 929 away from the arc groove 928 is recessed inward along the width direction of the angle adjustment plate 925 to form a bending groove. Under this setting, the connection strength between the inner plate 931 and the outer plate 930 can be reduced, and the force requirement of the inner plate 931 can be reduced, and the flexibility of the inner plate 931 can be improved, and when the horizontal adjustment member 926 and the vertical adjustment member 927 are used, it has higher stability and operability. In some embodiments, the horizontal adjustment member 926 includes two horizontal adjustment screws, and threaded holes connecting the arc groove 928 are provided on both sides of the outer plate 930 along the width direction of the angle adjustment plate 925. When the horizontal adjustment screw is tightly matched with the outer plate 930, the end of the horizontal adjustment screw contacts and abuts against the inner plate 931. Optionally, the vertical adjustment member 927 includes a vertical adjustment shaft 933, a connecting seat 934 and a butterfly spring 935;

[0152] The connecting seat 934 is installed and fixed on the bottom end surface of the outer plate 930, and one end of the connecting seat 934 is opposite to the inner plate 931. The inner plate 931 is provided with a threaded hole for the vertical adjustment shaft 933 to be screwed into.

[0153] The disc spring 935 is sleeved on the vertical adjustment shaft 933 and is located between the connecting seat 934 and the inner plate 931. During assembly, the tracking motor 904 is installed on the inner plate 931. After the two groups of horizontal adjustment screws are engaged with the threaded holes on the outer plate 930, they abut against the wall surface of the inner plate 931. By adjusting the feeding degree of the two groups of horizontal adjustment screws, the yaw angle of the tracking cutter 915 in the horizontal direction can be finely adjusted. The connecting seat 934 is fixedly connected to the outer plate 930. The vertical adjustment shaft 933 has an external thread. The vertical adjustment shaft 933 and the connecting seat 934 are oppositely arranged and are in threaded cooperation with the inner plate 931. The vertical adjustment shaft 933 contacts and abuts against the connecting seat 934 through the disc spring 935. When one end of the vertical adjustment shaft 933 protrudes from the inner plate 931 and abuts against the tracking motor 904, support is provided by the disc spring 935 and the connecting seat 934. By rotating the vertical adjustment shaft 933, the yaw angle of the tracking cutter 915 in the direction perpendicular to the angle adjustment plate 925 can be changed. By adjusting the horizontal adjustment screws separately or simultaneously and the vertical adjustment shaft 933, the axis direction of the tracking cutter 915 can be changed, and the axis of the tracking cutter 915 can be made parallel to the axis of the profiling template 917. For example, when the axis of the tracking cutter 915 is inclined to the left relative to the axis of the profiling template 917, first unscrew the left horizontal adjustment screw, screw in the right horizontal adjustment screw, and then screw in the left horizontal adjustment screw to fix it, and the axis of the tracking cutter 915 can be adjusted to tilt to the right by a certain angle; when the axis of the tracking cutter 915 is inclined in the vertical direction relative to the axis of the profiling template 917, rotate the vertical adjustment shaft 933 to change the threaded feeding depth of the vertical adjustment shaft 933 and the inner plate 931, and the axis of the tracking cutter 915 can be offset up and down by a certain angle in the vertical direction.

[0154] In addition, in order to improve the stability of the sheet during transportation and the stability and reliability of tracking trimming, the above-mentioned tracking mechanism 9 further includes a buffer assembly. The buffer assembly includes a swing cylinder 936, a first buffer member 937, and a second buffer member 938;

[0155] The first buffer member 937 is arranged at the end of the second guide rod 909;

[0156] The second buffer member 938 is located between the four-axis slide 913 and the vertical slide 911;

[0157] The fixed end of the swing cylinder 936 is connected to the vertical slide 911, and the output shaft of the swing cylinder 936 is connected to the four-axis slide 913.

[0158] In addition, due to the large acting force of the vertical cylinder 910 of the tracking mechanism 9 and the long movement span when the tracking mechanism 9 works up and down, the tracking mechanism 9 shakes slightly when moving up and down. To solve this problem, the above tracking mechanism 9 further includes a first limiting component 939 and a second limiting component 940;

[0159] The first limiting component includes a first limiting wheel 939a, a limiting seat 939b and an induction switch;

[0160] The first limiting wheel 939a is rotatably connected to the vertical sliding seat 911 through a rotating shaft. The axis of the first limiting wheel 939a is parallel to the axial direction of the motor shaft of the tracking motor 904. The limiting seat 939b is arranged on the pressing beam 17 of the edge banding machine, and the limiting seat abuts against the outer periphery of the first limiting wheel 939a. The induction switch is located on one side of the first limiting wheel 939a for sensing the relative position of the limiting seat 939b;

[0161] The second limiting component 940 includes a second limiting wheel 940a and a tracking limiting block 940b. The second limiting wheel 940a is rotatably connected to the tracking limiting block 940b through a rotating shaft, and the tracking limiting block 940b is fixedly arranged on the pressing beam 17 of the edge banding machine;

[0162] An anti-collision block 941 opposite to the second limiting wheel 940a is arranged on the guiding sliding seat 923. The anti-collision block 941 has an inclined guiding surface that abuts against the second limiting wheel 940a. When the tracking mechanism 9 is working, if the response time of the vertical cylinder 910 is slow, resulting in the front end of the plate about to leave the working range of the tracking mechanism 9 while the tracking mechanism 9 is still processing the front end of the plate, the output shaft of the guiding cylinder 922 remains in the advancing state. At this time, the front end of the plate may collide with the guiding sliding seat 923. Under the action of the anti-collision block 941, when the plate is about to leave the working range of the mechanism, the tracking mechanism 9 can quickly descend to avoid damaging the plate.

[0163] Optionally, the above tracking mechanism 9 further includes magnetic switches, which are arranged on the horizontal cylinder 906, the vertical cylinder 910, the guiding cylinder 922 and the swinging cylinder 936. Specifically, magnetic switches are also attached to the head and tail of the horizontal cylinder 906, the tail of the vertical cylinder 910, the head of the guiding cylinder 922, and the head and tail of the swinging cylinder 936 for real-time monitoring of the working process of the single-motor tracking and trimming mechanism 8.

[0164] The working process of the tracking mechanism 9 in this application is as follows:

[0165] After starting the edge banding machine, when the board is conveyed to the working station of the tracking mechanism 9 along the conveying direction, the tracking knife 915 starts to move and work, and the output shafts of the horizontal cylinder 906, the vertical cylinder 910 and the guiding cylinder 922 advance. The magnetic switches at the heads of the horizontal cylinder 906 and the guiding cylinder 922 light up. The swing cylinder 936 and the motor cylinder 916 contract, and the first limiting wheel 939a closely adheres to the lower surface of the limiting seat 939b. The board is conveyed on the edge banding machine from right to left. When the front end of the board reaches the position where the single-motor tracking trimming mechanism 8 is located, the left side of the board contacts the tracking guiding wheel 924, and the board pushes the tracking guiding wheel 924 and the tracking knife 915 synchronously to the left. The simultaneous action of the swing cylinder 936, the motor cylinder 916 and the horizontal cylinder 906 makes the tracking guiding wheel 924 always closely adhere to the left side of the board. At this time, the profiling wheel 918 is located at the upper left corner of the board. After the output shaft of the horizontal cylinder 906 contracts to a certain distance, the magnetic switch light at the head of the horizontal cylinder 906 goes out. The swing cylinder 936 first changes to the advancing state. After the swing cylinder 936 advances a certain distance, the magnetic switch light at the head of the swing cylinder 936 lights up, and the swing cylinder 936 returns to the contracting state again. At the same time, the vertical cylinder 910 pulls down the tracking knife 915 to process the upper left corner and the lower left corner of the board in sequence. The positional relationship among the tracking guiding wheel 924, the profiling wheel 918 and the board in this section of the action process is as Figure 22 shown.

[0166] When the magnetic switch light at the tail of the vertical cylinder 910 lights up, the processing operation of the tracking cutter 915 on the lower left corner of the plate is completed. That is, after the vertical cylinder 910 pulls the tracking cutter 915 away from the plate, the output shaft of the guiding cylinder 922 contracts, pulling the tracking guide wheel 924 down to disengage from the plate. The horizontal cylinder 906 first pushes the tracking guide wheel 924 and the tracking cutter 915 synchronously to the right back to the initial position. When the magnetic switch light at the head of the horizontal cylinder 906 lights up, the output shaft of the swing cylinder 936 becomes the advancing state. The output shaft of the guiding cylinder 922 extends, pushing the tracking guide wheel 924 upward. After the magnetic switch light at the head of the guiding cylinder 922 lights up, the output shaft of the horizontal cylinder 906 contracts, driving the tracking guide wheel 924 and the tracking cutter 915 to move left synchronously until the tracking guide wheel 924 closely adheres to the right side surface of the plate. At this time, the profiling wheel 918 is located at the lower right corner of the plate. After the output shaft of the horizontal cylinder 906 contracts to a certain distance, the magnetic switch light at the head of the horizontal cylinder 906 goes out. The swing cylinder 936 first becomes the contracting state. After the swing cylinder 936 contracts a certain distance, the magnetic switch light at the tail of the swing cylinder 936 lights up, and the swing cylinder 936 returns to the advancing state. At the same time, the vertical cylinder 910 pushes the tracking cutter 915 upward to process the lower right corner and the upper right corner of the plate in sequence. When the inductive switch senses the limit seat 939b, the first limit wheel 939a closely adheres to the lower surface of the limit seat 939b, and the processing operation of the tracking cutter 915 on the upper right corner of the plate is completed. That is, after the vertical cylinder 910 pulls the tracking cutter 915 away from the plate, the output shaft of the horizontal cylinder 906 advances, pushing the tracking guide wheel 924 and the tracking cutter 915 synchronously to the right. The output shaft of the swing cylinder 936 becomes the contracting state. The magnetic switch light at the head of the horizontal cylinder 906 lights up, and a working cycle ends. The positional relationship among the tracking guide wheel 924, the profiling wheel 918, and the plate from the end of the processing of the lower left corner of the plate to the end of the processing of the upper right corner is as Figure 23 shown.

[0167] The tracking mechanism 9 in the present application, compared with the tracking device of the existing edge banding machine, only uses one tracking motor 904 to complete the processing operations of the four corners of the plate. When the tracking mechanism 9 is installed on the frame 1, it is adjacent to the edge scraping mechanism 10. Among them, the horizontal cylinder 906 is horizontally fixed on the frame 1 and is located below the edge scraping mechanism 10, achieving simplification in layout and the purpose of reducing the overall length of the edge banding machine. By setting the angle adjustment component, without interfering with other components of the tracking mechanism 9, the yaw angles of the tracking motor 904 in the horizontal direction and the vertical direction can be freely adjusted, improving the running stability of the tracking motor 904 and avoiding poor tracking caused by the non-parallel axis between the tracking cutter 915 and the profiling template 917 due to reasons such as the machining accuracy of the parts of the tracking mechanism 9 and equipment wear. By setting the angle adjustment component, without increasing the manufacturing cost, the processing accuracy of the tracking mechanism 9 is ensured.

[0168] In a preferred embodiment, refer to Figures 24 to 31 , the above-mentioned upper scraping edge assembly 1000 and lower scraping edge assembly 1001 both include a mounting frame 1002, a longitudinal scraping edge unit 1003, a transverse scraping edge unit 1004 and a dust suction unit 1005;

[0169] The mounting frame 1002 includes a first sliding seat 1006, a second sliding seat 1007 and a scraper seat 1008;

[0170] The first sliding seat 1006 is used to adjust the position of the scraper seat 1008 in the horizontal direction, and the second sliding seat 1007 is used to synchronously adjust the position of the scraper seat 1008 in the horizontal and vertical directions;

[0171] The second sliding seat 1007 is inclined on the first sliding seat 1006. The end of the second sliding seat 1007 is connected to the scraper seat 1008, and a scraping edge knife 1009 is provided on the scraper seat 1008;

[0172] Both the longitudinal scraping edge unit 1003 and the transverse scraping edge unit 1004 are arranged on the scraper seat 1008;

[0173] The dust suction unit 1005 is arranged on the second sliding seat 1007 for removing scraping edge waste.

[0174] Further, the above-mentioned longitudinal scraping edge unit 1003 includes a longitudinal guide wheel 1010, a longitudinal adjustment seat 1011, a longitudinal adjustment screw rod 1012, a longitudinal optical axis 1013 and a longitudinal scraper 1014;

[0175] The longitudinal adjustment seat 1011 is slidably matched with the scraper seat 1008 through the longitudinal optical axis 1013. The longitudinal adjustment screw rod 1012 passes through the longitudinal adjustment seat 1011 and is threadedly connected to the scraper seat 1008. The longitudinal guide wheel 1010 is vertically installed on the longitudinal adjustment seat 1011 through a bearing structure, and the longitudinal scraper 1014 is arranged on the longitudinal adjustment seat 1011 and abuts against the outer peripheral surface of the longitudinal guide wheel 1010;

[0176] The transverse scraping edge unit 1004 includes a transverse guide wheel 1015, a transverse adjustment seat 1016, a transverse optical axis 1017, a transverse adjustment shaft 1018, a transverse cylinder 1019, a transverse cylinder 1019 seat and a transverse scraper 1021;

[0177] The transverse guide wheel 1015 is horizontally mounted on the transverse adjustment seat 1016 through a bearing structure; the transverse optical axis 1017 horizontally penetrates the transverse adjustment seat 1016, and the first end of the transverse optical axis 1017 is connected to the transverse scraping knife 1021, and the second end is connected to the transverse cylinder 1019 seat; the transverse adjustment shaft 1018 horizontally penetrates the transverse cylinder 1019 and is in threaded cooperation with the transverse adjustment seat 1016; the transverse cylinder 1019 is arranged on the transverse cylinder 1019 seat, and the output shaft of the transverse cylinder 1019 is connected to the transverse adjustment shaft 1018; the transverse scraping knife 1021 is arranged on the transverse adjustment seat 1016 and abuts against the outer peripheral surface of the transverse guide wheel 1015.

[0178] In the edge scraping mechanism 10 of the edge banding machine, a scraping work station capable of accommodating the sliding of the board is formed between the longitudinal edge scraping unit 1003 and the transverse edge scraping unit 1004. The scraping knife 1009 is located at the scraping work station. When the board slides at the scraping work station, it is in close contact with the scraping knife 1009, thereby realizing the edge scraping work of the board. The upper edge scraping assembly 1000 and the lower edge scraping assembly 1001 are mirror-symmetrical, and the upper edge scraping assembly 1000 is slidably connected to the pressing beam 17 of the edge banding machine through the mounting frame 1002, and the lower edge scraping assembly 1001 is slidably connected to the guide rail 18 of the edge banding machine through the mounting frame 1002. When scraping the edge of the board, the positions of the upper edge scraping assembly 1000 and the lower edge scraping assembly 1001 can be moved to adapt to different edge scraping work of the board. Under the action of the conveying mechanism 2, after the board arrives at the edge scraping mechanism 10, the longitudinal edge scraping units 1003 in the upper edge scraping assembly 1000 and the lower edge scraping assembly 1001 press the upper and lower surfaces of the board. That is to say, the two planes of the board are respectively on the same horizontal plane as the reference plane of the longitudinal edge scraping unit 1003, and one side of the board is closely attached to the transverse edge scraping unit 1004. Under the action of the conveying mechanism 2, the board is pushed to move, thereby realizing the edge scraping treatment.

[0179] Optionally, the above-mentioned edge scraping mechanism 10 further includes a second positioning unit 1022. The second positioning unit 1022 includes a connecting member and a rolling member. Connecting members are provided on both sides of the longitudinal edge scraping unit 1003. The rolling member is connected to the connecting member and is in rolling contact with the plate. In some embodiments, the rolling member is a bearing. Generally, different hole and groove structures are provided on the plate for subsequent furniture assembly work. When the longitudinal edge scraping unit 1003 falls into the hole and groove structure, the horizontal position of the plate changes, resulting in the reference plane of the longitudinal edge scraping unit 1003 not being on the same level as the surface of the plate, and finally the plate shakes or vibrates, affecting the subsequent edge scraping work of the edge scraping knife 1009. Therefore, to avoid and solve this problem, the reference plane of the second positioning unit 1022 coincides with the reference plane of the longitudinal edge scraping unit 1003. When the longitudinal edge scraping unit 1003 encounters the hole and groove structure, the reference plane of the second positioning unit 1022 can ensure that the relative position of the plate does not change and keep the two on the same level.

[0180] Optionally, the above-mentioned first sliding seat 1006 includes an edge scraping fixed seat 1023, a first sliding seat 1024, a first sliding optical axis 1025, a sliding adjustment plate 1026, and a spring;

[0181] The edge scraping fixed seat 1023 is installed on the pressure beam 17 and the guide rail 18 of the edge banding machine; the edge scraping fixed seat 1023 has a shaft hole passing through a linear bearing structure;

[0182] The first sliding seat 1024 and the first sliding optical axis 1025 are in sliding fit through a linear bearing;

[0183] The sliding adjustment plate 1026 is arranged on the first sliding seat 1024. Bolts are provided on the sliding adjustment plate 1026. The spring is sleeved on the bolts, and the axis of the bolts is parallel to the axis of the first sliding optical axis 1025;

[0184] One side of the first sliding seat 1024 away from the first sliding optical axis 1025 is an inclined surface;

[0185] The second sliding seat 1007 includes a fixing plate 1027, a second sliding optical axis 1028, a second sliding seat 1029, a sliding cylinder 1030, a sliding cylinder 1030 seat, and a support plate 1032;

[0186] The second sliding seat 1029 is arranged on the inclined surface of the first sliding seat 1024. The second sliding seat 1029 and the second sliding optical axis 1028 are in sliding fit through a linear bearing. The two ends of the second sliding optical axis 1028 are respectively connected to the fixing plate 1027 and the sliding cylinder 1030 seat;

[0187] The sliding cylinder 1030 is fixedly installed on the groove of the second sliding seat 1029. The output end of the sliding cylinder 1030 is connected to the sliding cylinder 1030 seat, and the sliding cylinder 1030 seat is connected to the scraper seat 1008 through a support plate 1032;

[0188] On the basis of the above specific implementation manner, the dust suction unit 1005 includes a dust suction hood 1033 connected to the sliding cylinder 1030 seat. The scraper seat 1008 is provided with a guide groove and a mounting hole. The air inlet of the dust suction hood 1033 faces the guide groove, the mounting hole is located on the inner side wall of the guide groove, and a blowing head 1034 is provided on the mounting hole. The edge scraping knife 1009 is located between the blowing head 1034 and the scraper seat 1008. A trachea is passed through the mounting hole, and the trachea communicates with the blowing head 1034. When the edge scraping mechanism 10 works, the air outlet holes of the blowing head 1034 discharge air, and the waste of the edge band flows in the guide groove under the action of the air flow and enters the dust suction hood 1033.

[0189] The working process of the edge scraping mechanism 10 in this application is as follows:

[0190] When the hanging edge scraping mechanism 10 is working, the board moves in the direction shown by the arrow. The board is first subjected to upper edge scraping treatment and then lower edge scraping treatment; the upper and lower surfaces of the board are pressed by the transverse guide wheels 1015, the longitudinal guide wheels 1010, and the bearings located on both sides of the longitudinal guide wheels 1010. The rolling surfaces of the bearings and the rolling surfaces of the longitudinal guide wheels 1010 are on the same horizontal plane. The transverse guide wheels 1015 and the longitudinal guide wheels 1010 are in close contact with the edge band on the side of the board, so that the upper and lower corners of the edge band are in contact with the edge scraping knife 1009. After the longitudinal guide wheels 1010 and the transverse guide wheels 1015 jointly position the board, the excess part on the edge band is scraped off by the edge scraping knife 1009 to complete the edge scraping treatment of the board.

[0191] As Figure 32 and Figure 33 shown, under normal conditions, the surface of the board is flat. At this time, the edges of the longitudinal guide wheels 1010 and the left and right bearings are in close contact with the surface of the board and slide along the conveying direction. When there are holes on the surface of the board, when the longitudinal guide wheel 1010 moves to the position of the hole, it will cause the guide wheel to not press on the board, which is likely to cause shaking. At this time, the second positioning unit 1022 plays a supporting role to support the board until the longitudinal guide wheel 1010 contacts the board again. An additional support surface is provided for the board through the reference surface of the second positioning unit 1022 to prevent the longitudinal guide wheel 1010 from shaking after falling into the hole structure and resulting in poor edge scraping.

[0192] In this embodiment, the edge scraping mechanism 10 suspends the upper edge scraping component 1000 and the lower edge scraping component 1001 on the pressure beam 17 and the guide rail 18 of the edge banding machine respectively, so that the edge scraping mechanism 10 is suspended relative to the machine frame 1. Compared with the edge scraping mechanism 10 in the existing edge banding machine, the structure is more compact. There is a certain space between the edge scraping mechanism 10 and the table top of the machine frame 1. This space serves as the installation station for the horizontal cylinder 906 in the tracking mechanism 9. With this setting, the space utilization rate of the edge banding machine is effectively improved, and the overall length of the edge banding machine is reduced.

[0193] In a preferred embodiment, please refer to Figure 34 , the above polishing mechanism 12 includes an upper polishing component 1200 and a lower polishing component 1201. The upper polishing component 1200 is fixedly arranged on the pressure beam 17, and the lower polishing component 1201 is fixedly arranged on the guide rail 18;

[0194] The upper polishing component 1200 includes an upper mounting seat 1202, a polishing adjustment screw rod 1203, a polishing adjustment block 1204 and a polishing mounting plate 1205. A slot is provided on the upper mounting seat 1202. The polishing adjustment screw rod 1203 is inserted into the slot and fixedly connected to the upper mounting seat 1202 through a fastener. The polishing adjustment screw rod 1203 is threadedly connected to the polishing adjustment block 1204. The polishing adjustment block 1204 is connected to the polishing mounting plate 1205, and a polishing motor 1206 is provided on the polishing mounting plate 1205.

[0195] The upper polishing component 1200 is fixedly connected to the pressure beam 17 of the edge banding machine. The upper mounting seat 1202 is fixedly connected to the polishing adjustment screw rod 1203, and the polishing adjustment screw rod 1203 is connected to the threaded hole of the polishing adjustment block 1204. The polishing adjustment block 1204 is fixedly connected to the polishing mounting plate 1205 and the polishing motor 1206 respectively. The polishing mounting plate 1205 is fixedly connected to the upper mounting seat 1202. A polishing wheel is fixedly connected to the motor shaft of the polishing motor 1206. First, loosen the fastener between the polishing mounting plate 1205 and the polishing adjustment block 1204, and rotating the polishing adjustment screw rod 1203 can change the position of the polishing motor 1206 in the vertical direction, and then change the position of the polishing wheel arranged on the polishing motor 1206. Loosen the fasteners between the polishing mounting plate 1205 and the upper mounting seat 1202, and between the polishing adjustment screw rod 1203 and the upper mounting seat 1202. After moving the polishing mounting plate 1205 back and forth, the position of the polishing wheel in the horizontal direction can be adjusted.

[0196] It should be noted that the upper polishing component 1200 and the lower polishing component 1201 have the same structure. Therefore, for the structure of the lower polishing component 1201, please refer to the structure of the upper polishing component.

[0197] Compared with the existing edge banding machines, under the condition of having the same functions, the edge banding machine provided by the present application integrates and assembles the trimming mechanism 8, the tracking mechanism 9, the scraping mechanism 10 and the flexible flat scraping mechanism 11, reducing the overall length of the machine by 25%, enabling it to adapt to more application scenarios.

[0198] The embodiments of the present application have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The choice of terms used herein is intended to best explain the principles of the embodiments, the practical application, or the improvement of the technology in the market, or to enable other ordinary skill in the art to understand the disclosed embodiments.
