[0032] Embodiment 1

[0033] like Figure 1-3 As shown, a veneer panel skin leveling device proposed by the utility model comprises a workbench 1, a fixing block 2, a mounting seat 3 and a pressing roller 4;

[0034] There are four fixing blocks 2, which are evenly installed on both sides of the workbench 1. The mounting seats 3 correspond to the fixing blocks 2 one by one, and one end of the mounting seat 3 is connected to the upper end surface of the fixing block 2.

[0035] The mounting seats 3 on both sides of the central axis along the width direction of the workbench 1 are symmetrically distributed, and two mounting seats 3 along the width direction of the workbench 1 form a group, and the pressing roller 4 is located inside a group of mounting seats 3, and the two ends of the pressing roller 4 are rotatably connected to the two mounting seats 3 respectively;

[0036] The workbench 1 is provided with a smoothing component for smoothing the panels of different heights;

[0037] The workbench 1 is provided with a position adjustment component for adjusting the position of the smoothing component;

[0038] The pressing roller 4 is provided with a driving and adjusting assembly for driving the pressing roller 4 to rotate and adapt to boards of different heights.

[0039] The driving and adjusting assembly includes a motor 5, a rotating shaft 12 and a telescopic device 13;

[0040] The rotating shaft 12 is located at the inner central axis of the pressure roller 4, and the two ends of the rotating shaft 12 are rotatably connected to the two mounting seats 3 on the same side along the width direction of the workbench 1;

[0042] The motor 5 corresponds one to one with a group of mounting seats 3 along the width direction of the workbench 1. The fixed end of the motor 5 is connected to a mounting seat 3 in any group of mounting seats 3 along the width direction of the workbench 1. The output end of the motor 5 passes through the motor 5 and is connected to one end of the rotating shaft 12. After the pressing roller 4 contacts the sheet skin, the protrusions on the sheet skin and the thickness of the sheet skin apply an extrusion force to the outer peripheral surface of the pressing roller 4. After the pressing roller 4 is subjected to the force, the telescopic device 13 inside the pressing roller 4 is extended or shortened according to the pressure, thereby forming different eccentricities between the pressing roller 4 and the rotating shaft 12, which is suitable for sheets with different protrusion sizes or different thicknesses.

[0043] The end face of the hot pressing plate 10 close to the workbench 1 is arc-shaped. By designing the contact surface between the hot pressing plate 10 and the board skin to be arc-shaped, the board skin will not be cut by the edges and corners of the hot pressing plate 10 when it is smoothed by the hot pressing plate 10, thereby increasing the protection of the safety of the board skin.

[0044] The projection of the mounting seat 3 is L-shaped, and the rotating shaft 12 and the pressure roller 4 can be stably fixed on the workbench 1 through the L-shaped mounting seat 3.

[0045] Embodiment 2

[0046] like Figure 1-3 As shown, the utility model proposes a veneer panel skin leveling device. Compared with the first embodiment, this embodiment further specifically discloses the specific structure of the leveling component and the position adjustment component.

[0047] In this embodiment, the smoothing assembly includes a first fixing seat 7, a connecting rod 8, a second fixing seat 9 and a hot pressing plate 10;

[0048] There are multiple first fixing seats 7 in total. The first fixing seats 7, connecting rods 8, and second fixing seats 9 correspond to each other one by one. The first fixing seats 7 and the second fixing seats 9 face in opposite directions and have the same shape.

[0049] The other end of each second fixing seat 9 is connected to one side of the hot pressing plate 10 and is evenly distributed on the hot pressing plate 10. There is a gap between the other end of the hot pressing plate 10 and the upper end surface of the workbench 1.

[0050] The position adjusting assembly includes a mounting frame 6 and a fixing bolt 11;

[0051] Chute grooves are provided on both sides of the workbench 1. The chute grooves are located between two fixing blocks 2 on the same side along the length direction of the workbench 1;

[0052] The projection of the mounting frame 6 is U-shaped. Sliders are provided at the proximal ends of the bottom of the mounting frame 6. The two sliders are respectively located in the chute grooves on both sides and are slidably connected to the workbench 1;

[0053] One end of each first fixing seat 7 away from the connecting rod 8 is connected to one side of the first fixing seat 7 and is evenly distributed on the first fixing seat 7;

[0054] A threaded hole a is provided on the side of the mounting frame 6 away from the slider. A threaded hole b is provided on the slider.

By tightening or loosening the fixing bolt 11 and adjusting the position of the mounting frame 6 through the chute grooves and the sliders, at the same time, when the board skin passes through the hot pressing plate 10, the hot pressing plate 10 flattens the protrusions on the board skin by gravity, and the cooperation of the first fixing seat 7, the second fixing seat 9, and the connecting rod 8 enables the hot pressing plate 10 to change the height of the hot pressing plate 10 according to the size of the protrusions so as to flatten the board skin, which is applicable to board skins with different thicknesses and different protrusion sizes.

[0055] In summary, in the present utility model, first, the board skin is placed on one side of the workbench 1 and one end of the board skin is pressed by the pressing roller 4. At this time, the motor 5 is turned on, and the motor 5 drives the rotating shaft 12 to rotate. At the same time, when encountering board skins with different thicknesses and different protrusion sizes, the telescopic device 13 inside the pressing roller 4 changes the eccentricity between the rotating shaft 12 and the pressing roller 4 according to the size of the protrusions or the thickness of the board skin, so as to adapt to board skins with different protrusion sizes or different thicknesses. At this time, the pressing roller 4 conveys the board skin to the hot pressing plate 10 through the friction force with the board skin. The conveyed board skin exerts a pushing force on the bottom contact surface of the hot pressing plate 10. At the same time, the arc surface at the bottom of the hot pressing plate 10 flattens the protrusions on the board skin through its own pressure, thus completing the whole process.

[0056] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
