The plate is always conveyed forward during the entire edge trimming process and will not stop, thereby greatly improving the edge trimming efficiency, and the edge trimming quality is very high. After edge trimming, the edge band will not be misaligned. In addition, by providing a support plate, the servo tracking edge trimming mechanism cuts the edge band of the plate against the support plate, so that the movement speed of the plate and the servo tracking edge trimming mechanism is always synchronized during edge trimming, making the edge trimming more precise.

In the non-cutting state, the backing plate 4 avoids the sheet 2 by longitudinal movement; the buffer mechanism f is arranged between the machine body 1 and the X-axis moving mechanism a, and when the sheet 2 and the backing plate 4 generate an interaction force, the backing plate 4 acts on the buffer mechanism f through the X-axis moving mechanism a; the sheet 2 is a sheet, and before trimming, the edge bands 5 are first pasted on both ends of the sheet, and then a relatively long edge band 5 is pasted on the side of the sheet to be trimmed, and the two ends of the edge band 5 are protruding respectively, and then the sheet can be put on the conveyor line 3 for transportation, and the edge band 5 protruding outwards is cut off by the trimming mechanism d during the sheet transportation, so that each edge band 5 can be aligned with each other, thereby improving the aesthetics of the sheet.

[0031] The backing plate 4 is connected to the detection end of the buffer mechanism f; during edge cutting, one end of the plate 2 conflicts with one end of the backing plate 4, and the other end of the plate 2 conflicts with the other end of the backing plate 4; the buffer mechanism f feeds back a detection signal to the control system (a sensor is provided on the buffer cylinder 23, and the sensor feeds back a detection signal to the control system when it detects that the X-axis movable rack 9 acts on the buffer cylinder 23), and the control system then controls the Z-axis moving mechanism b to drive the edge cutting mechanism d to move up and down to cut the edge banding 5 of the plate 2.

[0033] Buffer mechanism f Scheme 2 (see Fig.13 ), the buffer mechanism f includes an X-axis buffer spring A41, an X-axis buffer rod 42, an X-axis buffer mounting seat 43 and an X-axis buffer spring B44; the X-axis buffer mounting seat 43 is fixed to the body 1 through the bottom plate 33, the X-axis buffer rod 42 slides through the X-axis buffer mounting seat 43, both ends of the X-axis buffer rod 42 are respectively exposed to the X-axis buffer mounting seat 43, the X-axis buffer spring A41 and the X-axis buffer spring B44 are respectively coil springs and are sleeved on the surface of the X-axis buffer rod 42, and one end of the X-axis buffer spring A41 acts on one end of the X-axis buffer rod 42 The other end of the X-axis buffer spring A41 acts on the X-axis buffer mounting seat 43, one end of the X-axis buffer spring B44 acts on the other end of the X-axis buffer rod 42, the other end of the X-axis buffer spring B44 acts on the X-axis buffer mounting seat 43, and the X-axis buffer rod 42 is transmission-connected to the X-axis movable rack 9 in the X-axis moving mechanism a; the external force is transmitted to the X-axis buffer rod 42 through the X-axis movable rack 9, and the X-axis buffer rod 42 compresses any elastic part, and the elastic force of the elastic part finally reacts on the back plate 4 through the X-axis movable rack 9, thereby playing a buffering role.

[0034] The X-axis guide rail includes a first slide rail 31 and a first slider 32 . The X-axis movable rack 9 is connected to the first slide rail 31 . The first slider 32 is fixed on the bottom plate 24 . The first slide rail 31 and the first slider 32 are slidably matched.

[0035] When the interaction force is generated between the plate 2 and the support plate 4, the support plate 4 acts on the piston rod 33 of the buffer cylinder 23 through the Y-axis slide bar 12, the X-axis movable bracket 8, the X-axis servo motor 6, the X-axis gear 7 and the X-axis movable rack 9 in turn, so that the piston rod 33 is compressed and moved, and the X-axis movable rack 9 drives the first slide rail 31 to move in the direction of the buffer cylinder 23, playing a buffering role to prevent the interaction force (impact force) between the plate 2 and the support plate 4 from being too large and damaging the plate 2 and the support plate 4.

Since the piston rod 33 of the buffer cylinder 23 is connected to the X-axis movable rack 9, when the X-axis gear 7 rotates, the X-axis movable rack 9 will not move laterally, but the X-axis gear 7 will move laterally; the X-axis servo motor 6 is a servo motor.

[0037] The X-axis moving mechanism a also includes a brake assembly, which is arranged on the body 1 and corresponds to the X-axis movable rack 9; when the X-axis moving mechanism a drives the servo tracking edge cutting mechanism to move, the brake assembly acts on the X-axis movable rack 9 to fix it relative to the body 1. The brake assembly can perform a braking operation on the X-axis movable rack 9, that is, when the transfer assembly drives the servo tracking edge cutting mechanism to move, the brake assembly brakes the X-axis movable rack 9 to ensure that the servo tracking edge cutting mechanism moves effectively and accurately; when the back plate 4 is acted upon by an external force (when the back plate 4 collides with the plate 2), the brake assembly releases the X-axis movable rack 9 to ensure that the buffering force of the buffering mechanism f can eventually act smoothly on the back plate 4. It should be noted that in the non-braking state, the X-axis moving mechanism a can also work normally; Brake assembly solution 1 (see Figure 4 ), the brake assembly includes a brake transmission member 45 and a clamping brake cylinder 46; the brake transmission member 45 is connected to the X-axis movable rack 9, the clamping brake cylinder 46 is fixed on the body 1, and one end of the brake transmission member 45 extends to the clamping brake cylinder 46; the clamping brake cylinder 46 achieves braking by clamping one end of the brake transmission member 45; when the clamping brake cylinder 46 releases the brake transmission member 45, it can ensure that the buffering force can act on the back plate 4 through the X-axis movable rack 9.

[0051] The trimming method of the servo tracking trimming mechanism comprises the following steps: 1) The conveyor line 3 drives the plate 2 with the edge band 5 attached to be transported horizontally in the positive direction of the X-axis. When the plate 2 is transported to the corresponding position, one end of the plate 2 acts on one side of the support plate 4, and the brake assembly releases the X-axis movable rack 9. The support plate 4 acts on the buffer mechanism f through the X-axis moving mechanism a (the cylinder is compressed by about 5 mm). The buffer mechanism f feeds back the detection information to the control system. The control system starts the X-axis moving mechanism a and drives the servo tracking trimming mechanism to move from the initial position to the positive direction of the X-axis. The moving speed of the servo tracking trimming mechanism is the same as the conveying speed of the plate 2, so that the saw blade 22 on the trimming mechanism d and the support plate 4 respectively track the plate 2; then, the control system starts the Z-axis moving mechanism b and drives the saw blade 22 to move downward from the first cutting position O1 to the second cutting position O2 to cut the excess edge band 5 at one end of the plate 2; 2) The X-axis moving mechanism a drives the servo tracking trimming mechanism to accelerate and move in the positive direction of the X-axis (the brake assembly brakes the X-axis active rack 9). At this time, the moving speed of the trimming mechanism d is greater than the conveying speed of the plate 2, so that one side of the support plate 4 is about 10mm away from the plate 2; then, the Y-axis moving mechanism e drives the support plate 4 to retreat about 30mm, and the X-axis moving mechanism a drives the servo tracking trimming mechanism to move in the opposite direction of the positive direction of the X-axis (the brake assembly brakes the X-axis active rack 9). At the same time, the X-axis transverse profiling moving mechanism c drives the trimming mechanism d to move relatively transversely to the other side of the support plate 4 to reach the third cutting position O3; 3) The conveyor line 3 continues to drive the plate 2 to convey the plate 2 transversely in the positive direction of the X-axis; when the plate 2 exceeds the set distance (about 5mm) on the other side of the support plate 4, the Y-axis moving mechanism e drives the support plate 4 to extend, and the X-axis moving mechanism a drives the servo tracking trimming mechanism to accelerate in the positive direction of the X-axis (the brake assembly brakes the X-axis movable rack 9). At this time, the moving speed of the servo tracking trimming mechanism is greater than the conveying speed of the plate 2, so that the other side of the support plate 4 acts on the other end of the plate 2, and the support plate 4 acts on the buffer mechanism f through the X-axis moving mechanism a (the cylinder is compressed by about 5mm) (the brake assembly releases the X-axis movable rack 9), and the buffer mechanism f feeds back the detection information to the control system, and the control system controls the X-axis moving mechanism a to drive the servo tracking trimming mechanism to decelerate and move, so that the servo tracking trimming mechanism has the same conveying speed as the plate 2, so that the saw blade 22 and the support plate 4 track the plate 2 respectively; then, the control system starts the Z-axis moving mechanism b and drives the saw blade 22 to move upward from the third cutting position O3 to the fourth cutting position O4 to cut the excess edge banding 5 at the other end of the plate 2; 4) The X-axis moving mechanism a drives the servo tracking trimming mechanism to return to the initial position (the brake assembly brakes the X-axis movable rack 9), and the X-axis transverse profiling moving mechanism c drives the trimming mechanism d to move transversely from the fourth cutting position O4 to the first cutting position O1 relative to the support plate 4.
