[0033] The utility model realizes the up and down adjustment of the mounting seat 104 by setting the first buffer 301, so that the trimming knife 20 can adapt to wooden boards 90 of different thicknesses, and the edge to be trimmed of the wooden board 90 can be aligned with the cutting edge 201 of the trimming knife 20. The second buffer 302 is also set to slow down the large upward and downward movement of the mounting seat 104 caused by the wooden board 90 contacting the trimming knife 20, thereby improving the stability of the trimming knife 20 during the trimming process, avoiding the trimming knife 20 from moving up and down significantly during the trimming process, and improving the trimming accuracy.
[0034] In the embodiment of the present utility model, the first buffer 301 is a supporting spring.
[0035] It can be understood that one end of the first buffer 301 is fixedly connected to the suspension rod 103, and the other end of the first buffer 301 is fixedly connected to the mounting seat 104; specifically, one end of the support spring is fixedly connected to the suspension rod 103, and the other end of the support spring is fixedly connected to the mounting seat 104.
[0036] In the embodiment of the present invention, the second buffer 302 is a damper.
[0037] It can be understood that one end of the second buffer 302 is fixedly connected to the mounting seat 104, and the other end of the second buffer 302 is fixedly connected to the second fixing frame 102; specifically, the movable end of the damper is fixedly connected to the mounting seat 104, and the fixed end of the damper is fixedly connected to the second fixing frame 102; or the fixed end of the damper is fixedly connected to the mounting seat 104, and the movable end of the damper is fixedly connected to the second fixing frame 102, according to actual conditions and is not limited to this.
[0038] In the embodiment of the utility model, the mounting seat 104 and the first buffer 301 are both mounted on the suspension rod 103, the first buffer 301 is supported below the mounting seat 104, and a limiting block 105 is provided at the lower part of the suspension rod 103; specifically, there is a clearance fit between the mounting seat 104 and the suspension rod 103, and the support spring provides support force for the mounting seat 104.
[0039] When trimming is not performed, the mounting seat 104 remains stable and motionless under the action of its own gravity and the elastic force of the supporting spring; when trimming is performed, that is, when the trimming knife 20 contacts the wooden board 90, the trimming knife 20 interacts with the wooden board 90 and transmits the force to the mounting seat 104. The mounting seat 104 tends to move up and down. Due to the tension of the damper, the damper slows down the amplitude of the up and down movement of the mounting seat 104, thereby improving the trimming accuracy.
[0040] Specifically, the limit block 105 and the suspension rod 103 are made in one piece, or the limit block 105 and the suspension rod 103 are made in two pieces, and the two are connected as one piece by screws and nuts or welding.
[0041] In an embodiment of the utility model, the suspension rod 103 is a threaded rod, and the suspension rod 103 is threadedly connected to the first fixed frame 101; in this way, the position of the mounting seat 104 can be adjusted up and down by rotating the suspension rod 103, and the user can adjust the position of the mounting seat 104 according to the actual application scenario. In the process of adjusting the suspension rod 103 up and down, the second buffer 302 moves accordingly; of course, in other embodiments, the suspension rod 103 and the first fixed frame 101 can be fixedly connected. At this time, the suspension rod 103 remains stationary relative to the first fixed frame 101, and the up and down position of the suspension rod 103 cannot be adjusted.
[0042] In the embodiment of the present invention, the trimming knife 20 has a cutting edge 201 , and the cutting edge 201 is rounded or beveled.
[0043] Specifically, when the cutting edge 201 of the trimming knife 20 is rounded, a circular arc edge can be trimmed on the wooden board 90; when the cutting edge 201 of the trimming knife 20 is beveled, a chamfered edge can be trimmed on the wooden board 90, such as a beveled edge with an angle of 30°, 45°, 60°, etc.
[0044] In an embodiment of the utility model, a first positioning wheel 40 and a second positioning wheel 50 are respectively provided on the upper and lower sides of the trimming knife 20. The first positioning wheel 40 and the second positioning wheel 50 are both provided on the mounting seat 104. The side surface of the first positioning wheel 40 is used to fit the side surface of the wooden block, and the side surface of the second positioning wheel 50 is used to fit the top surface of the wooden board 90.
[0045] It is understandable that when the wooden board 90 is trimmed by the trimming knife 20 , the wooden board 90 needs to be positioned. Thus, the first positioning wheel 40 and the second positioning wheel 50 are used to position the side surface of the wooden board 90 and the top surface of the wooden board 90 respectively.
[0046] Specifically, the first positioning wheel 40 is disposed at a lower portion of one side of the trimming knife 20, and the second positioning wheel 50 is disposed at an upper portion of one side of the trimming knife 20. Figure 2 When in use, the user continues to push the wooden board 90 and makes the side surface of the wooden board 90 fit against the side surface of the first positioning wheel 40, and there is line contact between the wooden board 90 and the first positioning wheel 40, and the top surface of the wooden board 90 fits against the side surface of the second positioning wheel 50, and there is line contact between the wooden board 90 and the second positioning wheel 50, so that the edge between the side surface of the wooden board 90 and the top surface of the wooden board 90 is aligned with the cutting edge 201 of the trimming knife 20, and the wooden board 90 passes through the cutting edge 201 of the trimming knife 20 to achieve trimming of the edge; due to the action of the first buffer 301, wooden boards 90 of different thicknesses within a certain range can all enter between the first positioning wheel 40 and the second positioning wheel 50, and the second positioning wheel 50 can be pressed against the top surface of the wooden board 90, and the cutting edge 201 of the trimming knife 20 can be aligned with the edge to be trimmed of the wooden board 90, thereby improving applicability.
[0047] Specifically, the first positioning wheel 40 is rotatably connected to the mounting seat 104 via a rotating shaft and a bearing, so that the first positioning wheel 40 can rotate around its rotating shaft, thereby guiding the advancement of the wooden board 90; the second positioning wheel 50 is rotatably connected to the mounting seat 104 via a rotating shaft and a bearing, so that the second positioning wheel 50 can rotate around its rotating shaft, thereby guiding the advancement of the wooden board 90.
[0048] More specifically, the first positioning wheel 40 and the second positioning wheel 50 are both symmetrical structures. The first positioning wheel 40 is in a frustum shape or a cylinder shape, and the second positioning wheel 50 is in a frustum shape or a cylinder shape.
[0049] Furthermore, an adjustment mechanism may be provided to adjust the setting position of the first positioning wheel 40, so that the utility model can be applicable to wooden boards 90 of different shapes and sizes; of course, a first adjustment mechanism may be provided to adjust the position of the first positioning wheel 40, and a second adjustment mechanism may be provided to adjust the position of the second positioning wheel 50, so that the utility model can be applicable to wooden boards 90 of different shapes and sizes.
[0050] Furthermore, the adjustment mechanism includes an adjustment block and a base, the adjustment block and the base are slidably matched, the first positioning wheel 40 is fixedly connected to the adjustment block, and the position of the adjustment block is adjusted forward and backward along the base, that is, the position of the first positioning wheel 40 is adjusted forward and backward along the base. When the first positioning wheel 40 is adjusted forward and backward to a suitable position, the position of the adjustment block is locked using a locking member, such as a locking nut or a locking screw.
[0051] Of course, in other embodiments, an adjustment mechanism may also be provided to adjust the front and rear position, the up and down position, and the setting angle of the first positioning wheel 40 , so that it can be suitable for wooden boards 90 of different shapes and sizes.
[0052] In the embodiment of the utility model, guide posts 60 are disposed on both sides of the second fixing frame 102 , and the mounting seat 104 is sleeved on the guide posts 60 , and the mounting seat 104 and the guide posts 60 are movably connected.
[0053] Specifically, when the suspension rod 103 is a screw rod, the height of the suspension rod 103 can be adjusted up and down by rotating the suspension rod 103, so that the position of the mounting seat 104 can be adjusted up and down. At this time, the mounting seat 104 can move up and down along the guide column 60, and the guide column 60 provides guidance for the up and down movement of the mounting seat 104, thereby improving the stability of the up and down movement of the mounting seat 104.
[0054] In the embodiment of the utility model, a motor 70 is disposed on the mounting seat 104 , and the motor 70 is used to drive the trimming knife 20 to rotate; it can be understood that the trimming knife 20 is connected to the output end of the motor 70 .
[0055] Specifically, the motor 70 is detachably connected to the mounting base 104, and the mounting position of the motor 70 is selected according to the actual application scenario. After the position of the motor 70 is adjusted, the position of the motor 70 is locked using a locking member, such as a locking nut or a locking screw, so that the position of the trimming knife 20 can be adjusted.
[0056] It can be understood that when in use, the cutting edge 201 of the trimming knife 20 is aligned with the edge of the wooden board 90 to be trimmed, and the trimming knife 20 can remain stationary. The wooden board 90 passes through the cutting edge 201 of the trimming knife 20, and the trimming knife 20 can trim the wooden board 90. Of course, the speed of the trimming knife 20 driven by the motor 70 can also be controlled. When the speed of the trimming knife 20 reaches a predetermined speed, the wooden board 90 passes through the cutting edge 201 of the trimming knife 20, and the trimming knife 20 can also trim the wooden board 90.
[0057] In the embodiment of the utility model, a dust suction head 80 is disposed on the mounting seat 104 , and the dust suction head 80 is aligned with the trimming knife 20 .
[0058] Since the trimming knife 20 trims the wooden board 90 , dust and wood chips are generated in the process of trimming. The dust and wood chips generated in the process of trimming are sucked away by the dust suction head 80 to avoid pollution.
