[0021] Example 1

[0022] A trimming device for processing wood veneer panels, such as Figure 1-5As shown, it includes a seat plate 1, a mounting frame 2, a transmission shaft 3, a belt 4, a motor 5, a mounting frame 6, a transmission shaft 7, a belt 8, a motor 9 and a descending assembly; the seat plate 1 is bolted to two mounting frames 2 distributed in the front and rear; the two mounting frames 2 are connected to two transmission shafts 3 distributed in the left and right for common rotation; the two transmission shafts 3 are connected to the belt 4 for common rotation; the front mounting frame 2 is bolted to a motor 5 for driving the left transmission shaft 3 to rotate, and the output shaft of the motor 5 is connected to the left transmission shaft 1 3 is fixedly connected; the seat plate 1 is connected with an ascending and descending assembly; the ascending and descending assembly is connected with two mounting frames 26 distributed front and rear; the two mounting frames 26 are jointly connected with two transmission shafts 27 distributed left and right; the two transmission shafts 27 are jointly connected with a belt 28 for cooperating with a belt 14 to transmit the decorative panel; the front mounting frame 26 is bolted with a motor 29 for driving the left transmission shaft 27 to rotate, and the output shaft of the motor 29 is fixedly connected with the left transmission shaft 27; the ascending and descending assembly is used to drive the mounting frame 26 and the parts connected thereto to move up and down;

[0023] It also includes a limiting roller 10, a limiting roller 11 and a cutting assembly; two mounting frames 2 6 are rotatably connected to two limiting rollers 10 distributed on the left and right, and each limiting roller 10 is in contact with the inner side of the belt 2 8; the two mounting frames 2 6 are rotatably connected to the limiting roller 11, and the limiting roller 11 is in contact with the outer side of the belt 2 8, and the limiting roller 11 is located between the two limiting rollers 10; each mounting frame 2 6 is fixedly connected to a cutting assembly for trimming the decorative panel.

[0024] The ascending and descending assembly includes an electric push rod 101 and a connecting plate 102; the front and rear sides of the seat plate 1 are both bolted to two electric push rods 101; the telescopic portion of each electric push rod 101 is fixedly connected to a connecting plate 102, and all the connecting plates 102 are fixedly connected to the corresponding mounting frames 2 6.

[0025] The cutting assembly includes a bracket 201, an electric push rod 202 and a cutting knife 203; the mounting frame 2 6 is fixedly connected to the bracket 201; the bracket 201 is bolted to the electric push rod 202; the telescopic part of the electric push rod 202 is fixedly connected to the cutting knife 203.

[0026] The cutting assembly also includes a connecting plate 2 301, a connecting rod 302 and a clamping wheel 303; the telescopic portion of the electric push rod 202 is fixedly connected to the connecting plate 2 301; the connecting plate 2 301 is fixedly connected to two connecting rods 302 distributed up and down; each connecting rod 302 is rotatably connected to a clamping wheel 303 for clamping the burrs.

[0027] The specific operation of the above-mentioned embodiment 1 is as follows: first, the telescopic part of the electric push rod 101 is controlled to drive the mounting frame 2 6 and its connected parts to move downward through the connecting plate 102, so that the gap between the belt 2 8 and the belt 1 4 is equal to the thickness of the decorative panel, and then the output shaft of the motor 15 is controlled to drive the belt 14 to rotate clockwise from the front to the back as a reference through the left transmission shaft 13, and at the same time, the output shaft of the motor 29 is controlled to drive the belt 28 to rotate counterclockwise from the front to the back as a reference through the left transmission shaft 27, and the speed of the belt 14 is the same as that of the belt 28. In this process, through the setting of the two limiting rollers 10 and the limiting roller 2 11, the belt 28 forms a V-shaped space at the position where the three pass, and then the telescopic part of the electric push rod 202 is controlled to drive the cutting knife 203 to move in the V-shaped space, so that the cutting knife 203 is at the same level as the side of the decorative panel away from the electric push rod 202, so as to complete the preparation work;

[0028] Then, the veneer panel is manually placed in a horizontal state into the left side of the gap between the belt 2 8 and the belt 1 4, so that the belt 2 8 and the belt 1 4 cooperate to convey the veneer panel. In this process, the veneer panel is trimmed by the cutting knife 203 to remove the burrs on the veneer panel.

[0029] In this way, a V-shaped space is formed on the belt 2 8 by two limiting rollers 10 and 11, so that the cutting knife 203 can move in the gap between the belt 2 8 and the belt 1 4, so that the cutting knife 203 can trim the veneers of different widths, thereby avoiding the problem in the prior art that the upper side of the cutting knife needs to be higher than the upper surface of the veneer, resulting in the inability of the prior art to trim the veneer that is smaller than the belt width of the veneer guide conveyor;

[0030] It should be noted that since the gap between the two clamping wheels 303 is equal to the thickness of the burrs on the veneer, and the burrs of the veneer are between the two clamping wheels 303 during the transmission process, during the trimming process, the two clamping wheels 303 will cooperate to clamp the burrs on the veneer, so that the cutting knife 203 can stably trim the veneer.

[0031] Example 2

[0032] On the basis of Example 1, Figure 1-2 As shown, it also includes a bracket 2 401, an electric push rod 3 402 and a positioning plate 403; each mounting frame 2 6 is fixedly connected to a bracket 2 401; each bracket 2 401 is fixedly connected to two electric push rods 3 402; the telescopic parts of all the front electric push rods 3 402 are fixedly connected to a positioning plate 403, and the telescopic parts of all the rear electric push rods 3 402 are fixedly connected to another positioning plate 403; the positioning plate 403 is used to position the decorative panel.

[0033] A guide portion 403 a is disposed on the left side of each positioning plate 403 .

[0034] The side of the positioning plate 403 away from the electric push rod 3 402 is set to be a smooth surface.

[0035] The specific operation of the above-mentioned embodiment 1 is as follows: Considering that during the conveying process of the veneer panel, when the veneer panel is offset, the cutting knife 203 cannot trim the veneer panel normally;

[0036] Therefore, when manually placing the decorative panel between the second belt 8 and the first belt 4, the telescopic part of the third electric push rod 402 is first controlled to push the positioning plate 403 to move toward the middle of the first belt 4, so that the gap between the two positioning plates 403 is equal to the width of the decorative panel, so that in the process of the second belt 8 and the first belt 4 cooperating to transport the decorative panel, the decorative panel is restricted by the two positioning plates 403 to prevent the decorative panel from shifting;

[0037] It should be noted that, by cooperating with the two guide parts 403a, the decorative panel can be quickly placed between the two positioning plates 403 manually. At the same time, since the side of the positioning plate 403 away from the electric push rod 402 is set to a smooth surface, the positioning plate 403 will not affect the transmission of the decorative panel.

[0038] Although the present invention has been described with reference to exemplary embodiments, it should be understood that the present invention is not limited to the disclosed exemplary embodiments. The scope of the following claims is to be accorded the broadest interpretation so as to encompass all modifications and equivalent structures and functions.
