Therefore, a set of trimming mechanisms 25 are provided on both sides of the conveying roller table 1. The two sets of trimming mechanisms 25 are arranged facing each other.

The control device 252 in the trimming mechanism 25 may be a rotating structure or a telescopic structure, and the blade 251 may be arranged above the facing material 2 on the conveying roller table 1 or may be arranged below the conveying surface of the conveying roller table 1. In the embodiment shown in FIGS. 6-1 to 6-3 and FIG. 7, the control device 252 is a rotating structure located above the facing material 200. For example, a rotating cylinder can be selected.

After the facing material 200 is coated with a bonding agent and pressed onto the decorative surface of the base material 100, as the base material 100 is continuously conveyed on the conveying roller table 1, the edge trimming mechanism 25 separates the adjacent base materials 100 After the veneer material 200 is cut along the edge of the base material 100, the first pressing mechanism 4 is used to bend the edge of the veneer material 200 and press the side and the bottom surface of the base material 100.

Wherein, the top surface pressing roller 401 is located above the base material 100 and the facing material 200, and the edges of the facing material 200 are fully pressed onto the decorative surface of the base material 100, and the axial direction of the top surface pressing roller 401 is in line with the base material. The width direction of 100 is parallel; the top surface pressing roller 401 is used to fully press the facing material 200 and the top surface edge of the base material 100 to prevent the facing material 200 from wrinkling when the edges of the facing material 200 are subsequently bent And affect the decoration quality and decoration effect. The axial direction of the top side pressing roller 402 is set at an acute angle with the width direction of the base material 100, and the side wall of the top side pressing roller 402 fully presses the facing material 200 on the top edge of the base material 100 (that is, the edge of the decorative surface) At this point, it is used to bend the facing material 200 along the top edge of the base material 100 toward the side surface of the base material 100. The axial direction of the side pressure roller 403 is parallel to the thickness direction of the substrate 100, that is, it is arranged perpendicular to the decorative surface of the substrate 100. The side wall of the side pressure roller 403 fully presses the decorative material 200 on the side surface of the substrate 100. As the substrate 100 advances, the side pressing roller 403 rotates, so as to fully press the facing material 200 with the side surface of the substrate 100. The axial direction of the bottom pressing roller 404 is set at an acute angle with the width direction of the substrate 100, and is used to bend the facing material 200 along the bottom edge of the substrate 100 toward the bottom surface of the substrate 100; the axial direction of the bottom pressing roller 405 is the same as The width direction of the base material 100 is parallel and located below the base material 100, and is used for pressing the facing material 200 with the bottom surface of the base material 100.

Wherein, when there are two or more top side press rollers 402, the angle between the axis of each top side press roller 402 and the decorative surface of the substrate 100 can be the same, or it can be gradually along the conveying direction of the conveying roller table 1. Correspondingly, when there are two or more bottom side press rollers 404, the angle between the axis of each bottom side press roller 404 and the bottom surface of the substrate 100 can be the same, or along the conveyor roller 1 The conveying direction gradually decreases.

In addition, when the number of top surface pressing rollers 401 is multiple, the plurality of top surface pressing rollers 401 may be all arranged before the top pressing roller 402, or may be distributed and arranged before the top pressing roller 402, the top pressing roller 402 and the top pressing roller 402. Between the side pressure rollers 403 and between the side pressure roller 403 and the bottom side pressure roller 404.

After the edges of the facing material 200 and the base material 100 are fully pressed by the first pressing mechanism 4, the cutting mechanism 3 applies the cutting mechanism 3 to the facing material between the adjacent base materials 100 during the conveying process of the conveying roller table 1. 200 is cut so that the facing material 200 and the two ends of the base material 100 are pressed together subsequently. Figure 10 shows a schematic plan view of the cutting mechanism 3 on the conveying roller table 1, and Figure 11 shows a schematic side view of the cutting mechanism 3. As shown in Figures 10 and 11, in this embodiment , The cutting mechanism 3 includes a tracking cutting machine 31 diagonally straddling the conveying roller table 1 and a first dust collecting device 32 located below the conveying roller table 1 and along the cutting trajectory of the tracking cutting machine 31. The tracking cutting machine 31 is used in Under the control of the control center 300, the facing material 200 between the adjacent substrates 100 is cut as the substrate 100 travels on the conveying roller table 1, and the first dust collecting device 32 is used to collect the tracking cutter 31 Dust such as paper scraps generated during the cutting process of the facing material 200.

Specifically, the tracking cutter 31 includes a track 311 arranged diagonally above the conveying roller table 1, a drive motor 312 located at one end of the track 311, a cutting motor 313, and a cutting sheet 314, wherein the cutting motor 313 is slidably connected to the track 311, and It is drivingly connected to the output end of the driving motor 312, and the cutting blade 314 is fixedly connected to the output end of the cutting motor 313. The driving motor 312 and the cutting motor 313 are both signal-connected to the control center 300. Under the control of the control center 300, the driving motor 312 drives the cutting motor 313 to drive the cutting blade 314 to slide along the track 311, while the cutting motor 313 drives the cutting blade 314 to rotate at a high speed. The facing material 200 is cut laterally. When the driving motor 312 drives the cutting motor 313 to move diagonally across the conveying roller 1 along the conveying direction of the conveying roller 1 on the track 311, the moving speed component of the cutting motor 313 in the conveying direction of the conveying roller 1 and the conveying roller 1 The conveying speed of 1 is equal to ensure that the cutting sheet 314 cuts across the facing material 200 perpendicular to the side surface of the substrate 100.

FIG. 12 shows a schematic diagram of the cutting blade 314 in a specific embodiment when cutting the facing material 200. As shown in the figure, in order to ensure the flatness of the cutting end surface, the cutting blade 314 may be ultra-thin without teeth. For the saw blade, for example, a toothless saw blade with a thickness of 1 mm may be used, and the extension surface of the cutting blade 314 is arranged perpendicular to the conveying direction of the conveying roller table 1.

Referring back to FIG. 10 and FIG. 11, since the track 311 is arranged diagonally, in order to realize online cutting along with the operation of the conveying roller table 1, the cutting sheet 314 can only be cut in one direction. After each cutting is completed, the motor 312 needs to be driven to drive the cutting motor 313 and the cutting blade 314 to return to their original positions. In order to prevent damage to the facing material 200 during the restoration of the cutting blade 314 to the original position, the cutting blade 314 needs to be raised to a certain height. Therefore, the tracking cutter 31 also includes a lifting assembly 315, the cutting motor 313 is fixedly connected with the output end of the lifting assembly 315, and the lifting assembly 315 is drivingly connected with the output end of the driving motor 312 and slidingly connected with the rail 311. For example, the lifting assembly 315 may be a lifting cylinder or other lifting or telescoping devices.

Below the middle of the conveying surface of the conveying roller table 1, at a position corresponding to the starting end of the tracking cutter 31, or a predetermined distance from the starting end of the tracking cutter 31 along the conveying direction of the conveying roller table 1, a position with the control center 300 is provided. The signal-connected second detector 102 is used to detect the edge position of the end of the substrate 100, that is, to detect the traveling position of the substrate 100, and feed it back to the control center 300 in real time. As a result, the operation of the tracking cutter 31 is controlled.

The control center 300 controls the conveying roller 1 to convey the substrate 100 placed at predetermined intervals at a predetermined speed. When the substrate 100 passes over the second detector 102, the second detector 102 can detect the signal of the substrate 100; After completely passing through the second detector 102, the second detector 102 has no signal output. Therefore, when there is no signal output from the second detector 102, the control center 300 determines that the previous substrate 100 has passed over the second detector 102, and when the second detector 102 outputs a signal again, it is determined to be the next substrate 100. It begins to pass over the second detector 102, and in this process is the interval between two adjacent substrates 100.

The control center 300 calculates that the second detector cannot receive the second sensor according to the parameters such as the conveying interval between adjacent substrates 100, the conveying speed of the conveying roller table 1, and the distance between the second detector 102 and the starting end of the tracking cutter 31. How long the signal of the detector 102 starts or how many pulses thereafter, the tracking cutter 31 is controlled to start. Exemplarily, when a current piece of substrate 100 passes over the second detector 102, the second detector 102 sends the detected signal to the control center 300 in real time.
