[0037] Based on the above structure, the utility model uses the adjustment mechanism 30 to adjust the positioning wheel 10 so that the positioning wheel 10 fits one surface of the wooden board 70, realizes the line contact between the positioning wheel 10 and the wooden board 70, improves the positioning accuracy of the wooden board 70, and uses the trimming knife 20 to trim the wooden board 70. The utility model can be applicable to different wooden boards 70.
[0038] In an embodiment of the utility model, the cutting edge 201 of the trimming knife 20 has rounded corners; since the cutting edge 201 of the trimming knife 20 is rounded, a circular arc edge can be trimmed on the wooden board 70; of course, in other embodiments, the cutting edge 201 of the trimming knife 20 has a bevel angle, and since the cutting edge 201 of the trimming knife 20 is beveled, a chamfered edge can be trimmed on the wooden board 70, such as a bevel edge with an angle of 30°, 45°, 60°, etc.
[0039] In the embodiment of the utility model, the trimming knife 20 is driven to rotate by a motor 40 .
[0040] When in use, the cutting edge 201 of the trimming knife 20 is aligned with the edge to be trimmed of the wooden board 70, and the trimming knife 20 can remain stationary. After the wooden board 70 passes through the trimming knife 20 along the positioning wheel 10, the trimming knife 20 can trim the wooden board 70. Of course, the speed of the trimming knife 20 driven by the motor 40 can also be controlled. When the speed of the trimming knife 20 reaches a predetermined speed, the wooden board 70 passes through the trimming knife 20 along the positioning wheel 10, and the trimming knife 20 can also trim the wooden board 70.
[0041] In an embodiment of the utility model, the adjustment mechanism 30 includes a base 301, a first adjustment block 302 and a second adjustment block 303.

The second adjustment block 303 is arranged on the first adjustment block 302, and the second adjustment block 303 is movably connected to the first adjustment block 302. The positioning wheel 10 is rotatably connected to the second adjustment block 303 through a rotating shaft.
[0042] In this way, the positioning wheel 10 can rotate around its central axis to facilitate the advancement of the auxiliary board 70; Figure 4 The installation angle between the positioning wheel 10 and the second adjusting block 303 is fixed. Of course, in other embodiments, the installation angle between the positioning wheel 10 and the second adjusting block 303 may also be adjustable.
[0043] In an embodiment of the utility model, the adjustment mechanism 30 includes an arc groove 304 and an arc block 305, the arc groove 304 and the arc block 305 cooperate with each other, the arc groove 304 is provided on the base 301, and the arc block 305 is provided on the first adjustment block 302, or the arc block 305 is provided on the base 301, and the arc groove 304 is provided on the first adjustment block 302; the first adjustment block 302 is movably connected to the base 301 by moving the arc block 305 on the arc groove 304.
[0044] Specifically, the arc block 305 and the arc groove 304 cooperate with each other, and there is surface contact between the arc block 305 and the arc groove 304. Compared with the method of directly using a rotating shaft to achieve a rotational connection, the cooperation between the arc block 305 and the arc groove 304 improves the stability of the connection between the two. When the arc block 305 moves to a predetermined position along the arc groove 304, the first locking piece 308 is used to lock the first adjustment block 302 and the base 301. The first locking piece 308 can be directly set on the arc block 305, thereby eliminating the need for multi-point locking and simplifying the locking process.
[0045] Specifically, see Figure 5In order to improve the connection stability between the arc block 305 and the arc groove 304, the cross section of the arc groove 304 is "T"-shaped, and the cross section of the arc block 305 is also "T"-shaped, thereby preventing the arc block 305 from falling off during the movement along the arc groove 304.
[0046] In an embodiment of the utility model, the adjustment mechanism 30 includes a linear groove 306, which is arranged on the first adjustment block 302, and the linear groove 306 extends along the length direction of the first adjustment block 302, and the second adjustment block 303 slides with the linear groove 306; or the linear groove 306 is arranged on the second adjustment block 303, and the linear groove 306 extends along the length direction of the second adjustment block 303, and the first adjustment block 302 slides with the linear groove 306; the adjustment mechanism 30 also includes an adjusting screw 307, the second adjustment block 303 is sleeved on the adjusting screw 307, the adjustment block is threadedly connected to the adjusting screw 307, and the second adjustment block 303 is driven to move relative to the first adjustment block 302 by rotating the adjusting screw 307.
