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

[0098] See also Figure 1 , Figure 1 It is a schematic diagram of the structure of the edge banding machine shown in the embodiment of the present application.

[0099] The present application provides an edge banding machine, comprising 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 belt feeding mechanism 5, a pressing mechanism 6, an end trimming mechanism 7, a trimming mechanism 8, a tracking mechanism 9, a scraping mechanism 10, a flexible flat scraping mechanism 10 and a polishing mechanism 12 are sequentially arranged along the conveying direction of the conveying mechanism 2;

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

[0102] The tracking mechanism 9 includes a horizontal moving component 900, a vertical moving component 901, a tracking component 902 and a guiding component 903. The horizontal moving component 900 is used to drive the tracking component 902 to move horizontally, and the vertical moving 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, and the guiding component 903 is used to position and guide the plate so that the tracking component 902 moves synchronously with the side of the plate.

[0103] The scraping mechanism 10 includes an upper scraping assembly 1000 slidably disposed on the pressure beam 17 of the frame 1 and a lower scraping assembly 1001 slidably disposed on the guide rail 18 of the frame 1 , and an installation station for the horizontal moving assembly 900 is formed between the lower scraping assembly 1001 and the frame 1 .

[0104] Specifically, the pre-milling mechanism 3, the belt feeding mechanism 5, the gluing mechanism 4, the pressing mechanism 6, the end trimming mechanism 7, the trimming mechanism 8, the tracking mechanism 9, the scraping mechanism 10, the flexible flat scraping mechanism 10, the polishing mechanism 12, and the conveying motor are sequentially installed on the edge banding machine frame 1 along the forward direction of the conveying mechanism 2, and the conveying motor is connected to the conveying mechanism 2 for providing power to the conveying mechanism 2.

[0105] The pre-milling mechanism 3 is used to pre-mill the edge of the plate that needs edge sealing. It can eliminate the adverse effects of plate edge breakage caused by poor sawing and other reasons, and improve the edge sealing quality. The belt feeding mechanism 5, the gluing mechanism 4, and the pressing mechanism 6 together form a group of gluing components for EVA glue gluing. The gluing mechanism 4 can realize EVA glue gluing, and has the function of automatically cleaning the glue door edge to eliminate the glue clumping and blockage to realize glue pot cleaning, which can also improve product quality and processing efficiency.

[0106] The tape feeding mechanism 5 can automatically cut the edge banding according to the length of the board and deliver the edge banding to the board that needs edge banding. The pressing mechanism 6 is used to press the edge banding delivered by the tape feeding mechanism 5 onto the board. After the board is glued, the edge banding on both sides of the board is slightly longer than the board, and the trimming mechanism 7 trims the excess edge banding on both sides of the board.

[0107] The trimming mechanism 8 is used for finely trimming the upper and lower edges of the plate after edge banding.

[0108] The tracking mechanism 9 is used to round the four right angles of the edge of the plate after edge sealing into arc angles.

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

[0110] The flexible flat scraping mechanism 10 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 to avoid the tool scratching the board when the surface of the board is uneven.

[0111] The polishing mechanism 12 is used to remove the edge burrs of the edge band and the residual glue between the edge band and the wooden board, so that the edge of the wooden board is cleaner and smoother.

[0112] It can be understood that the pre-milling mechanism 3, the gluing mechanism 4, the belt feeding mechanism 5, the end trimming mechanism 7 and the flexible flat scraping mechanism 10 are all prior arts, and therefore will not be described in detail one by one here.

[0113] The edge banding machine provided by the present application is optimized and designed around the structures of the trimming mechanism 8, the tracking mechanism 9 and the scraping mechanism 10. Firstly, the unused space on the frame 1 of the edge banding machine is effectively utilized. In the case of no interference, the horizontal moving assembly 900 of the tracking mechanism 9 is arranged under the scraping mechanism 10 to improve the utilization rate of the frame 1. Secondly, the scraping mechanism 10 is flexible to install and can move freely on the guide rail 18 and the pressure beam 17. Compared with the existing scraping mechanism 10, it occupies a smaller installation space, effectively improving the space utilization rate, and helping to reduce the overall length of the edge banding machine, so that it meets the use requirements of small-volume edge banding machines. Finally, the upper trimming assembly 800 and the lower trimming assembly 801 of the trimming mechanism 8 are located on the same side and are arranged horizontally. In terms of structure, it is more compact than the existing trimming mechanism 8, realizing the miniaturization of the trimming mechanism 8 and the overall size, which meets the application occasions with smaller space.

[0114] Compared with the prior art, the scraping mechanism 10 of the present invention is suspended on the pressure beam 17 and the guide rail 18 of the frame 1, freeing up installation space for the tracking mechanism 9, and adopts a tracking motor 904 to track and trim the four corners of the plate. The structure cooperates with the horizontal moving component 900, the vertical moving component 901 and the guide component 903 for multi-directional adjustment of the line of sight, ensuring that the tracking knife 915 can always be in contact with the plate to achieve rounded corner processing, which has a more prominent beneficial effect.

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

[0116] In a preferred embodiment, see Figures 1 to 4 A material pressing mounting plate 13 is provided on the frame 1 and on one side of the polishing mechanism 12. The material pressing mounting plate 13 is provided with a plurality of material pressing wheels 14 arranged side by side. A material discharging end of the conveying mechanism 2 is provided with a material discharging plate 15. The material pressing wheel 14 is located above the junction between the material discharging end and the material discharging plate 15. The material pressing wheel 14 is used to position and press the upper end surface of the plate;

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

[0118] like Figure 5 As shown, the pressing mechanism 6 in the present application uses a three-wheel pressing method to press the edge banding bonded to the plate. The pressing cylinder 602 is used to control the working state of the pressing mechanism 6. When the pressing mechanism 6 is in standby, the output shaft of the pressing cylinder 602 shrinks, and the pressing mounting seat 601 is away from the plate. When the pressing mechanism 6 is running, the output shaft of the pressing cylinder 602 advances, and the pressing mounting seat 601 approaches the plate. The three pressing wheel cylinders 605 independently control the main pressing wheel 603 and the two tapered pressing wheels to press the edge banding on the plate.

[0119] In actual application, the edge banding machine uses a conveying motor to connect the sprocket and drive the chain block 16 to convey the plate. The chain block 16 gradually rotates and moves downward around the sprocket axis. In addition, the length limit of the edge banding machine pressure beam 17 leads to insufficient positioning of the upper and lower end faces of the short plate, and the plate corners are easy to hit the discharge plate 15. Therefore, in order to solve this problem, a pressure mounting plate 13 is set on the pressure beam 17 and located at the intersection, and the pressure wheel 14 is connected to the pressure mounting plate 13 through a rotating shaft. The pressure wheel 14 is set at the discharge end of the edge banding machine. Through the pressure wheel 14, the positioning ability of the discharge end of the edge banding machine on the end face of the plate can be strengthened, and the discharge plate 15 can be effectively prevented from hitting the plate.

[0120] In a preferred embodiment, see Figures 6 to 12 The trimming mechanism 8 further comprises a stand 804, wherein the stand 804 is provided with a first sliding shaft group 805 and a second sliding shaft group 806 which are parallel to each other, wherein the bottom end surface of the first sliding shaft group 805 and the top end surface of the second sliding shaft group 806 are located on the same horizontal plane, wherein the upper trimming assembly 800 is slidably connected to the stand 804 via the first sliding shaft group 805, and the lower trimming assembly 801 is slidably connected to the stand 804 via the second sliding shaft group 806;

The motor mounting plate 809 is arranged on the trimming adjustment seat 808, and the trimming motor 802 is installed 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 of the trimming adjustment seat 808. A finishing station for trimming the plate is formed between the first positioning unit 810 and the lateral adjustment unit 811, and the trimming knife 803 is located at the finishing station; the reference surface of the first positioning unit 810 and the end surface of the plate are located in the same horizontal plane;

[0124] The trimming slide seat 807 is provided with an adjusting screw 813 that abuts against the trimming adjustment seat 808;

[0125] The stand 804 is also provided with a first height adjustment member 814 and a second height adjustment member 815 . The first height adjustment member 814 is used to adjust the horizontal height of the upper trimming assembly 800 , and the second height adjustment member 815 is used to adjust the horizontal height of the lower trimming assembly 801 .

[0126] For further information, see Fig.11 , and combined with Fig. 9 The first height adjustment member 814 includes a hanger 816, a hanger seat 817, an adjustment rod 819 and two adjustment springs 818. The hanger 816 is fixed on the pressure beam 17 of the edge banding machine. The hanger seat 817 is arranged on the trimming slide 807. The adjustment rod 819 passes through the trimming slide 807 and is threadedly connected to the hanger 816. The end of the adjustment rod 819 has a head extending outward. The two adjustment springs 818 are sleeved on the adjustment rod 819. The two adjustment springs 818 are respectively located between the hanger 816 and the hanger seat 817 and between the hanger seat 817 and the head of the adjustment rod 819.

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

[0128] The two sides of the dovetail slide 837 are respectively provided with a first dovetail groove and a second dovetail groove;

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

[0130] Optionally, the stand 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, Fig.12 As shown, the trimming mechanism 8 is mainly composed of an upper trimming assembly 800 , a lower trimming assembly 801 and a stand 804 . The first sliding shaft group 805 and the second sliding shaft group 806 are both composed of two optical axes. The upper end of the first sliding shaft group 805 is fixed to the connecting plate 816a by screws, and the lower end passes through the two holes of the first bracket plate 816b and is fixed to the second bracket plate 816c by using a machine to support the flat position; the upper and lower ends of the second sliding shaft group 806 are respectively fixed to the second bracket plate 816c and the trimming base 816f; the left and right screw holes of the first bracket plate 816b and the second bracket plate 816c correspond to the middle four holes of the front bracket plate 816d and the rear bracket plate 816e, and are installed between the front bracket plate 816d and the rear bracket plate 816e by screws; the upper three holes of the front bracket plate 816d and the rear bracket 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 hanger 816 is installed on the pressure beam 17 of the machine so that its spatial position is fixed; the adjusting rod 819 is fixed to the hanger 816 by a nut after passing through the hanger 817, wherein springs are provided between the end of the adjusting rod 819 and the hanger 817, and between the hanger 817 and the hanger 816; rotating the nut for fixing the adjusting rod 819 can change the vertical position of the adjusting rod 819 relative to the hanger 817, thereby changing the vertical position of the hanger 817.

[0132] In this embodiment, the trimming slide 807 of the upper trimming assembly 800 is the upper trimming slide 807, and the trimming slide 807 of the lower trimming assembly 801 is the lower trimming slide 807, wherein both the upper trimming slide 807 and the lower trimming slide 807 are embedded with linear bearings 812; the upper trimming slide 807 can slide between the connecting plate 816a and the first bracket plate 816b along the first slide shaft group 805; the lower trimming slide 807 can slide between the second bracket plate 816c and the trimming base 816f along the second slide shaft group 806. The four holes on the upper trimming slide 807 and the four holes of the hanging seat 817 are fixed with screws, and the upper trimming slide 807 can move vertically up and down with the hanging seat 817, and 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 squeezed by the plate and moves upward, the elastic force of the spring provides downward pressure, so that the upper trimming assembly 800 has the effect of being close to the plate.

[0133] The bottom of the lower trimming slide 807 is in contact with the first adjustment member (i.e., spring and bolt) on the trimming base 816f, with one end of the spring in contact, and the other end of the spring is installed on a bolt; the spring provides the lower trimming slide 807 with a force to push it upward all the time; a limit block is installed on the side of the lower trimming slide 807, which corresponds to a screw of the first bracket plate 816b, and abuts against each other when the lower trimming slide 807 moves vertically upward, so as to limit the lower trimming slide 807 to a reasonable working height; the force provided by the spring to the lower trimming slide 807 can be adjusted by adjusting the height of the bolt. Since the lower trimming assembly 801 is supported by the spring, when the lower trimming assembly 801 is squeezed by the plate and moves downward, the elastic force of the spring provides an upward pressure to make the lower trimming assembly 801 close to the plate.

[0134] In this embodiment, the structure of the upper trimming assembly 800 is similar to that of the lower trimming assembly 801. A sliding optical axis is provided on the linear bearing 812, and the sliding optical axis is arranged parallel to the axis of the motor shaft. The two ends of the sliding optical axis are fixed on the baffle and the trimming adjustment seat 808; the sliding optical axis is slidably connected with the upper trimming slide 807. The screw passes through a spring and the inner hole of the baffle in turn and then matches with the threaded hole of the upper trimming slide 807; the spring is compressed, generating a pressure that pushes the upper trimming slide 807 to the left, so that it slides horizontally to the left relative to the upper trimming slide 807; the adjusting screw 813 is used as a limiting device, which, after matching with the thread on the baffle, passes through the baffle and abuts against the upper trimming slide 807; by turning the adjusting screw 813 to change the protruding length of the front end of the screw relative to the baffle, the distance that the baffle moves to the left can be limited. The baffle, the sliding optical axis, and the trimming adjustment seat 808 are fixed, so the trimming adjustment seat 808 can be limited to a reasonable horizontal position. Since the baffle is supported by a spring, when the upper trimming assembly 800 is squeezed by the plate and the trimming adjustment seat 808 slides to the right, the spring provides a leftward pressure to keep the upper trimming assembly 800 close to the plate. The trimming adjustment seat 808 is slidably connected to the lateral adjustment unit 811 through the guide rail 18. The lateral adjustment unit 811 includes a main connecting shaft 820, a secondary connecting shaft 821, a trimming bearing seat 822, a trimming cylinder 823, a first pad 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 pad 832, a trimming limit block 833, a trimming slider 834, a trimming guide rail 83518 and a linear guide seat. The two secondary connecting shafts 821 and the main connecting shaft 820 are locked on the front end of the bearing structure by screws, and the main and secondary connecting shafts 821 are embedded with transverse bearings; the main and secondary connecting shafts 821 are eccentric shafts, and when the shafts are rotated, the protruding length of the edge of the transverse bearing relative to the edge of the left end of the trimming bearing seat 822 can be fine-tuned, so that the edges of the three transverse bearings are in the same plane for the best, and the rolling contact surface of the positioning member with the plate and the end surface of the plate are located in the same plane. The trimming adjustment seat 808 and the counter seat 828 are connected and fixed by bolts. The trimming cylinder 823 and the first pad 824 are screwed to the rear end of the trimming bearing seat 822, and the shaft of the trimming cylinder 823 is screwed into the first trimming adjustment shaft 825, and the front end of the first trimming adjustment shaft 825 passes through the trimming bearing seat 822 and is screwed into the counter seat 828.The two trimming counters 831 are mounted on the second pad 832, and the second pad 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 threadedly engaged with the second locking washer 827; the third trimming adjustment shaft 830 passes through the counter seat 828 and is threadedly engaged with the first locking washer 826 and the trimming bearing seat 822; the second trimming adjustment shaft 829 and the third trimming adjustment shaft 830 can be moved relative to the trimming counter 831. Perform a certain amount of axial movement; the first locking washer 826 and the second locking washer 827 are respectively fixed on the trimming bearing seat 822 and the counter seat 828, and the two locking washers play the role of tightening the thread to prevent the fit from loosening; the two holes at one end of the trimming limit block 833 are connected and fixed with the 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 washer 826, and the third trimming adjustment shaft 830 will pass through the trimming bearing seat 822 and press on the trimming limit block 833. When the axis of the trimming cylinder 823 extends, the trimming bearing seat 822 moves to the left along the guide rail 18 relative to the counter seat 828 until the third trimming adjustment shaft 830 hits the trimming limit block 833; when the axis of the trimming cylinder 823 contracts, the trimming bearing seat 822 moves to the right along the guide rail 18 relative to the counter seat 828 until the second trimming adjustment shaft 829 hits 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 limited. At the same time, the trimming cylinder 823 can not only drive the trimming bearing seat 822 to do a reciprocating linear motion, but also provide pressure to make the three transverse bearings fixed at the front end of the trimming bearing seat 822 always close 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 the motor mounting plate 809 and the hinge hole device are fixed on the trimming adjustment seat 808 and move 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 described in detail.

[0135] In this embodiment, the adjusting element includes a first fixing block 840, a first adjusting bolt 841, a first length 842, a second fixing block 843, a second adjusting bolt 844, a second length 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. The positioning slider 838 is fixed to the fixing seat 839 by screws, and the positioning slider 838 is nested in the dovetail groove in the middle of the dovetail slider 837, and the dovetail slider 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 845 passes through the middle round hole of the second adjusting bolt 844 and the middle round hole of the second fixing block 843 and is screwed into the threaded hole of the dovetail slide 837, and the other end is screwed into two nuts; 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 slide 838 by two screws. When adjusting the up and down position of the dovetail slide 837 as a whole, 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 845 upward, and the dovetail slide 837 slides upward accordingly. When adjusted to a suitable position, the two nuts can be locked again. A second adjusting seat 847 is fixed in the middle of the dovetail slide 837, which can move up and down with the dovetail slide 837. The first adjustment seat 846 and the third adjustment seat 848 are embedded in the dovetail grooves on both sides of the dovetail slide 837; the two first fixing blocks 840 are fixed on the dovetail slide 837 by two screws respectively, the two first adjustment bolts 841 are screwed into the first fixing block 840, and the two first long machine rices 842 pass through the circular hole in the middle of the first adjustment bolt 841 and the first fixing block 840 and finally screwed into the first adjustment seat 846 and the third adjustment seat 848; the first adjustment seat 846 and the third adjustment seat 848 can move up and down with the dovetail slide 837. The up and down positions of the first adjustment seat 846 and the third adjustment seat 848 relative to the dovetail slide 837 can be adjusted in the same way as the up and down positions of the dovetail slide 837. The first adjustment seat 846, the second adjustment seat 847, and the third adjustment seat 848 are all provided with vertical bearings 849, and the installation method is to press the vertical bearings 849 on the three adjustment seats through the bearing sleeve 850, and then tighten them with screws.

[0136] like Figures 14 to 16As shown, when the mechanism is in operation, the plate moves in the direction of the arrow, passing through the upper trimming part first and then the lower trimming part. The upper and lower trimming components 801 each contain a hinge hole device, and the edges of the three vertical bearings 849 of the hinge hole device are all on the same plane; the upper and lower trimming components 801 each contain a bearing seat, and the edges of the three transverse bearings fixed on the bearing seat are all on the same plane; the vertical bearings 849 and transverse bearings of the upper and lower trimming components 801 are always close to the plate, so as to accurately position the trimming knife 803 of the upper trimming component 800 and the trimming knife 803 of the lower trimming component 801. The upper and lower ends of the edge banding tape pasted on the plate are in contact with the trimming knife 803 of the upper trimming component 800 and the trimming knife 803 of the lower trimming component 801. The trimming knife 803 of the upper trimming component 800 and the trimming knife 803 of the lower trimming component 801 will cut off the upper and lower excess parts of the edge banding tape as the motor shaft rotates at high speed.

[0137] like Fig.13 As shown, under normal circumstances, the three vertical bearings 849 slide closely against the surface of the plate; when a hole is opened on the surface of the plate, the bearings on the middle second adjustment seat 847 cannot press the plate, and the bearings on both sides are responsible for supporting the plate until the bearings on the middle second adjustment seat 847 contact the plate again. In this way, the mechanism can be maintained to press the plate all the time, which can prevent the problem of unstable trimming of the plate with holes.

[0138] In a preferred embodiment, see Figures 17 to 23 The horizontal moving assembly 900 includes a base 905, a horizontal cylinder 906 and a horizontal slide 907. The base 905 is fixed on the frame 1. The horizontal slide 907 is slidably connected with the base 905 through a slide rail. The horizontal cylinder 906 is fixed on the base 905, and the output shaft of the horizontal cylinder 906 is connected to the horizontal slide 907. The horizontal slide 907 is vertically provided with a first guide rod 908 and a second guide rod 909. The guide assembly 903 is penetrated by the second guide rod 909.

[0139] The vertical moving assembly 901 includes a vertical cylinder 910 and a vertical slide 911, wherein the vertical slide 911 is penetrated by a first guide rod 908, the vertical cylinder 910 is disposed on a horizontal slide 907, and the output shaft of the vertical cylinder 910 is connected to the vertical slide 911;

[0140] The vertical slide 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 tracking assembly 902 includes a four-axis slide 913, a motor bracket 914, a tracking knife 915, a motor cylinder 916, a profiling mold 917, a profiling wheel 918, a fixing block 919, a tracking adjustment screw rod 920 and a scraping knife 921;

[0142] The four-axis slide 913 is penetrated by a third guide rod 912, a fourth guide rod 933 is provided at the bottom of the motor bracket 914, the axis of the third guide rod 912 is perpendicular to the axis of the third guide rod 912, and the motor bracket 914 is slidably connected to the four-axis slide 913 through the fourth guide rod 933;

[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 bracket 914, and the axis of the motor cylinder 916 is parallel to the axis of the fourth guide rod 933;

[0144] The profiling template 917 is disposed on one side of the motor bracket 914, the motor shaft of the tracking motor 904 is located on the circumference of the profiling template 917, and the profiling wheel 918 is connected to the motor shaft of the tracking motor 904;

[0145] The fixing block 919 is disposed on a side surface of the motor bracket 914 away from the profiling mold 917, and the tracking adjustment screw rod 920 passes through the fixing block 919 and is threadedly connected to the motor bracket 914;

[0146] The scraper blade 921 is disposed on one end surface of the profiling mold 917 facing the motor bracket 914;

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

[0148] The guide slide 923 is sleeved with a second guide rod 909, and the tracking guide wheel 924 is rotatably connected to the guide slide 923 via a rotating shaft, and the axial end surface of the tracking guide wheel 924 is parallel to the axial end surface of the tracking knife 915;

[0149] The guide cylinder 922 is used to drive the guide 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 member 926 and a vertical adjustment member 927. The angle adjustment plate 925 is located between the mounting seat 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 butterfly 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, and the two sets of horizontal adjustment screws are matched with the threaded holes on the outer plate 930 and abut against the wall surface of the inner plate 931. By adjusting the feeding degree of the two sets of horizontal adjustment screws, the swing angle of the tracking knife 915 in the horizontal direction can be fine-tuned. The connecting seat 934 is connected and fixed to the outer plate 930. The vertical adjustment shaft 933 has an external thread, and the vertical adjustment shaft 933 and the connecting seat 934 are arranged opposite to each other and are threadedly matched with the inner plate 931. The vertical adjustment shaft 933 contacts and abuts against the connecting seat 934 through the butterfly spring 935. When one end of the vertical adjustment shaft 933 is exposed from the inner plate 931 and abuts against the tracking motor 904, it is supported by the butterfly spring 935 and the connecting seat 934. By rotating the vertical adjustment shaft 933, the yaw angle of the tracking knife 915 in the vertical direction relative to the angle adjustment plate 925 can be changed. By adjusting the horizontal adjustment screw and the vertical adjustment shaft 933 separately or simultaneously, the axial direction of the tracking knife 915 can be changed, and the axis of the tracking knife 915 can be made parallel to the axis of the profiling template 917. For example, when the axis of the tracking knife 915 is tilted to the left relative to the axis of the profiling template 917, the horizontal adjustment screw on the left side is first screwed out, the horizontal adjustment screw on the right side is screwed in, and then the horizontal adjustment screw on the left side is screwed in to fix, so that the axis of the tracking knife 915 can be tilted to the right by a certain angle; when the axis of the tracking knife 915 is tilted in the vertical direction relative to the axis of the profiling template 917, the vertical adjustment shaft 933 is rotated to change the thread feed depth of the vertical adjustment shaft 933 and the inner plate 931, so that the axis of the tracking knife 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 plate during transportation and the stability and reliability of tracking trimming, the tracking mechanism 9 further includes a buffer assembly, which includes a swing cylinder 936, a first buffer member 937 and a second buffer member 938;

[0155] The first buffer member 937 is disposed 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 force of the vertical cylinder 910 and the long span of movement of the tracking mechanism 9 when working up and down, the tracking mechanism 9 shakes slightly when moving up and down. To solve this problem, the tracking mechanism 9 further includes a first limit assembly 939 and a second limit assembly 940.

[0159] The first limiting assembly 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 slide 911 via 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 pressure beam 17 of the edge banding machine, the limiting seat abuts against the outer periphery of the first limiting wheel 939a, and the induction switch is located on one side of the first limiting wheel 939a, and is used to sense the relative position of the limiting seat 939b;

[0161] The second limiting assembly 940 includes a second limiting wheel 940a and a tracking limiting block 940b, wherein the second limiting wheel 940a is rotatably connected to the tracking limiting block 940b via a rotating shaft, and the tracking limiting block 940b is fixedly mounted on the pressure beam 17 of the edge banding machine;

[0162] The guide slide 923 is provided with an anti-collision block 941 opposite to the second limit wheel 940a, and the anti-collision block 941 has an inclined guide surface abutting against the second limit wheel 940a. When the tracking mechanism 9 is working, if the vertical cylinder 910 has a slow response time, causing the front end of the plate 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 guide cylinder 922 remains in a propulsion state, and the front end of the plate may return to the guide slide 923 to collide with the plate. 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 tracking mechanism 9 further includes a magnetic switch, which is arranged on the horizontal cylinder 906, the vertical cylinder 910, the guide cylinder 922 and the swing cylinder 936. Specifically, the head and tail of the horizontal cylinder 906, the tail of the vertical cylinder 910, the head of the guide cylinder 922, and the head and tail of the swing cylinder 936 are also provided with magnetic switches for real-time monitoring of the working progress of the single-motor tracking trimming mechanism 8.

[0164] The tracking mechanism 9 in this application works as follows:

[0165] After the edge banding machine is started, when the sheet is transported to the working station of the tracking mechanism 9 along the conveying direction, the tracking knife 915 starts to move, the output shafts of the horizontal cylinder 906, the vertical cylinder 910 and the guide cylinder 922 are pushed forward, the magnetic switch at the head of the horizontal cylinder 906 and the magnetic switch at the head of the guide cylinder 922 are lit, the swing cylinder 936 and the motor cylinder 916 are retracted, and the first limit wheel 939a is in close contact with the lower surface of the limit seat 939b. The sheet is transported on the edge banding machine from right to left. When the front end of the sheet reaches the position of the single motor tracking trimming mechanism 8, the left side of the sheet contacts the tracking guide wheel 924, and the sheet pushes the tracking guide wheel 924 and the tracking knife 915 to the left synchronously. The simultaneous action of the swing cylinder 936, the motor cylinder 916 and the horizontal cylinder 906 makes the tracking guide wheel 924 always in close contact with the left side of the sheet. At this time, the profiling wheel 918 is located at the upper left corner of the sheet. After the output shaft of the horizontal cylinder 906 is retracted to a certain distance, the magnetic switch light on the head of the horizontal cylinder 906 goes out, and the swing cylinder 936 first changes to the advancing state. After the swing cylinder 936 advances a certain distance, the magnetic switch light on the head of the swing cylinder 936 turns on, and the swing cylinder 936 returns to the retracted state. 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 plate in turn. The positional relationship between the tracking guide wheel 924, the profiling wheel 918 and the plate in this section of the action process is shown in FIG. Fig. 22 shown.

[0166] When the magnetic switch light at the tail of the vertical cylinder 910 is on, the processing action of the tracking knife 915 on the lower left corner of the plate is completed, that is, after the vertical cylinder 910 pulls the tracking knife 915 away from the plate, the output shaft of the guide cylinder 922 shrinks, and the tracking guide wheel 924 is pulled down and separated from the plate. The horizontal cylinder 906 first pushes the tracking guide wheel 924 and the tracking knife 915 to the right to return to the initial position synchronously, and the magnetic switch light at the head of the horizontal cylinder 906 is on. At this time, the output shaft of the swing cylinder 936 changes to the propulsion state, and the output shaft of the guide cylinder 922 extends to push the tracking guide wheel 924 upward. After the magnetic switch light at the head of the guide cylinder 922 is on, the output shaft of the horizontal cylinder 906 shrinks, driving the tracking guide wheel 924 and the tracking knife 915 to move left synchronously until the tracking guide wheel 924 is close to the right side 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 is retracted to a certain distance, the magnetic switch light at the head of the horizontal cylinder 906 goes out, and the swing cylinder 936 first changes to a retracted state. After the swing cylinder 936 is retracted to a certain distance, the magnetic switch light at the tail of the swing cylinder 936 turns on, and the swing cylinder 936 resumes the advancing state. At the same time, the vertical cylinder 910 pushes the tracking knife 915 upward to process the lower right corner and the upper right corner of the plate in turn. When the induction switch senses the limit seat 939b, the first limit wheel 939a is close to the lower surface of the limit seat 939b, and the processing action of the tracking knife 915 on the upper right corner of the plate is completed, that is, after the vertical cylinder 910 pulls the tracking knife 915 away from the plate, the output shaft of the horizontal cylinder 906 is pushed forward, and the tracking guide wheel 924 and the tracking knife 915 are synchronously pushed to the right, the output shaft of the swing cylinder 936 changes to a retracted state, and the magnetic switch light at the head of the horizontal cylinder 906 turns on, and a working cycle ends. The positional relationship between the tracking guide wheel 924, the contour 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 follows: Fig.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 operation of the four corners of the plate. When the tracking mechanism 9 is installed on the frame 1, it is adjacent to the scraping mechanism 10. The horizontal cylinder 906 is horizontally fixed on the frame 1 and is located below the scraping mechanism 10, which simplifies the layout and achieves the purpose of reducing the overall length of the edge banding machine. By setting the angle adjustment component, the yaw angle of the tracking motor 904 in the horizontal direction and in the vertical direction can be freely adjusted without interfering with other components of the tracking mechanism 9, thereby improving the operating stability of the tracking motor 904 and avoiding poor tracking caused by the non-parallel axis between the tracking knife 915 and the profiling mold 917 due to the machining accuracy of the parts of the tracking mechanism 9, equipment wear, etc. By setting the angle adjustment component, the machining accuracy of the tracking mechanism 9 is guaranteed without increasing the manufacturing cost.

[0168] In a preferred embodiment, see Figures 24 to 31 The upper scraping assembly 1000 and the lower scraping assembly 1001 each include a mounting frame 1002, a longitudinal scraping unit 1003, a transverse scraping unit 1004 and a dust collecting unit 1005;

[0174] Furthermore, the longitudinal scraping 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 via 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 mounted on the longitudinal adjustment seat 1011 via 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 unit 1004 includes a transverse guide wheel 1015, a transverse adjustment seat 1016, a transverse optical axis 1017, a transverse adjustment axis 1018, a transverse cylinder 1019, a transverse cylinder 1019 seat and a transverse scraper 1021;

[0177] The transverse guide wheel 1015 is horizontally installed on the transverse adjustment seat 1016 through a bearing structure; the transverse optical axis 1017 horizontally passes through the transverse adjustment seat 1016, and the first end of the transverse optical axis 1017 is connected to the scraper, and the second end is connected to the transverse cylinder 1019 seat; the transverse adjustment shaft 1018 horizontally passes through the transverse cylinder 1019, and is threadedly matched 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 scraper 1021 is arranged on the transverse adjustment seat 1016, and abuts against the outer peripheral surface of the transverse guide wheel 1015.

[0178] The scraping mechanism 10 in the edge banding machine has a scraping station that can accommodate the sliding of the plate formed between the longitudinal scraping unit 1003 and the transverse scraping unit 1004, and the scraping knife 1009 is located on the scraping station. When the plate slides on the scraping station, it is in close contact with the scraping knife 1009, thereby achieving the scraping of the plate. The upper scraping assembly 1000 and the lower scraping assembly 1001 are mirror-symmetrical, and the upper scraping assembly 1000 is slidably connected to the pressure beam 17 of the edge banding machine through the mounting frame 1002, and the lower scraping assembly 1001 is slidably connected to the guide rail 18 of the edge banding machine through the mounting frame 1002. When scraping the plate, the positions of the upper scraping assembly 1000 and the lower scraping assembly 1001 can be moved to adapt to different plate scraping operations. Under the action of the conveying mechanism 2, after the plate arrives at the scraping mechanism 10, the upper scraping assembly 1000 and the longitudinal scraping unit 1003 in the lower scraping assembly 1001 press the upper and lower surfaces of the plate, that is, the two planes of the plate are respectively at the same horizontal plane as the reference plane of the longitudinal scraping unit 1003, and one side of the plate is close to the transverse scraping unit 1004, which pushes the plate to move under the action of the conveying mechanism 2, thereby realizing the scraping process.

[0179] Optionally, the scraping mechanism 10 further includes a second positioning unit 1022, which includes a connecting member and a rolling member. Connecting members are provided on both sides of the longitudinal scraping unit 1003, and the rolling member is connected to the connecting member, and the rolling member 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 to facilitate subsequent furniture assembly work. When the longitudinal scraping unit 1003 falls into the hole and groove structure, the horizontal position of the plate changes, resulting in the reference surface of the longitudinal scraping unit 1003 and the surface of the plate not being at the same level, and finally the plate shakes or shakes, affecting the subsequent scraping work of the scraping knife 1009. Therefore, in order to avoid solving this problem, the reference surface of the second positioning unit 1022 is overlapped with the reference surface of the longitudinal scraping unit 1003. When the longitudinal scraping unit 1003 encounters the hole and groove structure, the reference surface of the second positioning unit 1022 can be used to ensure that the relative position of the plate does not change, and the two can be kept on the same horizontal plane.

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

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

[0182] The first sliding seat 1024 and the first sliding optical axis 1025 are slidably matched via a linear bearing;

[0183] The sliding adjustment plate 1026 is disposed on the first sliding seat 1024 , and a bolt is disposed on the sliding adjustment plate 1026 , and a spring is sleeved with the bolt, and the axis of the bolt is parallel to the axis of the first sliding optical axis 1025 ;

[0184] A side surface 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 supporting plate 1032;

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

[0187] The sliding cylinder 1030 is installed and fixed on the groove of the second sliding seat 1029, and 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 the support plate 1032;

[0188] On the basis of the above-mentioned specific implementation mode, the above-mentioned 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 scraper 1009 is located between the blowing head 1034 and the scraper seat 1008. An air pipe is passed through the mounting hole, and the air pipe is connected to the blowing head 1034. When the scraping mechanism 10 is working, the air outlet of the blowing head 1034 discharges air, and the waste material of the edge banding tape flows in the guide groove under the action of the airflow and enters the dust suction hood 1033.

[0189] The scraping mechanism 10 in the present application has the following working process:

[0190] When the suspended scraping mechanism 10 is working, the plate moves in the direction indicated by the arrow, and the plate is first scraped up and then scraped down; the upper and lower surfaces of the plate are pressed by the transverse guide wheel 1015, the longitudinal guide wheel 1010 and the bearings on both sides of the longitudinal guide wheel 1010, and the rolling surface of the bearing and the rolling surface of the longitudinal guide wheel 1010 are on the same horizontal plane. The transverse guide wheel 1015 and the longitudinal guide wheel 1010 are close to the edge banding on the side of the plate, so that the upper and lower corners of the edge banding are in contact with the scraping knife 1009. After the longitudinal guide wheel 1010 and the transverse guide wheel 1015 work together to position the plate, the scraping knife 1009 scrapes off the excess part of the edge banding to complete the scraping of the plate.

[0191] like Fig.32 and Fig.33 As shown, in a normal state, the surface of the plate is flat, and the edges of the longitudinal guide wheel 1010 and the left and right bearings are close to the surface of the plate and slide along the conveying direction. When a hole is opened on the surface of the plate, when the longitudinal guide wheel 1010 moves to the position of the hole, the guide wheel cannot press the plate, which is prone to shaking. At this time, the second positioning unit 1022 plays a supporting role to support the plate until the longitudinal guide wheel 1010 contacts the plate again. The reference surface of the second positioning unit 1022 provides an additional support surface for the plate, so as to avoid shaking of the longitudinal guide wheel 1010 after falling into the hole structure, resulting in poor scraping.

[0192] In this embodiment, the scraping mechanism 10 adopts a hanging manner to install the upper scraping component 1000 and the lower scraping component 1001 on the pressure beam 17 and the guide rail 18 of the edge banding machine respectively, so that the scraping mechanism 10 is suspended relative to the frame 1. Compared with the scraping mechanism 10 in the existing edge banding machine, the structure is more compact. There is a certain space between the scraping mechanism 10 and the table of the frame 1, and the space is used as the installation position of the horizontal cylinder 906 in the tracking mechanism 9. Under this setting, the space utilization rate of the edge banding machine is effectively improved, which plays a role in reducing the overall length of the edge banding machine.

[0193] In a preferred embodiment, see Fig.34 The polishing mechanism 12 includes an upper polishing assembly 1200 and a lower polishing assembly 1201, wherein the upper polishing assembly 1200 is fixed on the pressure beam 17, and the lower polishing assembly 1201 is fixed on the guide rail 18;

[0194] The upper polishing assembly 1200 includes an upper mounting seat 1202, a polishing adjustment screw 1203, a polishing adjustment block 1204 and a polishing mounting plate 1205. The upper mounting seat 1202 is provided with a slot, the polishing adjustment screw 1203 is inserted in the slot and is fixed to the upper mounting seat 1202 by fasteners, the polishing adjustment screw 1203 is threadedly connected to the polishing adjustment block 1204, the polishing adjustment block 1204 is connected to the polishing mounting plate 1205, and the polishing mounting plate 1205 is provided with a polishing motor 1206.

[0195] The upper polishing assembly 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 1203, and the polishing adjustment screw 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. The motor shaft of the polishing motor 1206 is fixedly connected to the polishing wheel. First, loosen the fasteners between the polishing mounting plate 1205 and the polishing adjustment block 1204, and rotate the polishing adjustment screw 1203 to change the position of the polishing motor 1206 in the vertical direction, thereby changing the position of the polishing wheel set 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 1203 and the upper mounting seat 1202, and move the polishing mounting plate 1205 back and forth, and then adjust the position of the polishing wheel in the horizontal direction.

[0196] It should be noted that the upper polishing assembly 1200 and the lower polishing assembly 1201 have the same structure, so the structure of the lower polishing assembly 1201 refers to the structure of the upper polishing assembly.

[0197] Compared with the existing edge banding machines, while having the same functions, the edge banding machine provided in the present application integrates the trimming mechanism 8, the tracking mechanism 9, the scraping mechanism 10 and the flexible flat scraping mechanism 11, reducing the length of the entire machine by 25%, so that it can adapt to more application scenarios.
