[0046] Reference Figure 6The edge banding thickness adjustment mechanism includes a handle 28, a position digital display 29, two connecting rods 30, a spring 31, an adjusting nut 32, a screw 33, and a mounting plate 60. The two connecting rods 30 are connected to a sliding block 34. One end of each connecting rod 30 is connected to the mounting plate 60.

An adjusting nut 32 is connected to one side, and a spring 31 is sleeved on the surface of the screw 33 between the adjusting nut 32 and the mounting plate 60. Since the sliding block 34 cannot move axially, and the mounting plate 60 is connected to it through the connecting rod 30, the mounting plate 60 cannot move axially either. When the handle 28 is turned, since the handle 28 and the screw 33 are connected by an internal thread, the screw 33 can be driven to move axially back and forth under the force of the thread. Since the screw 33 is locked on the support plate 5, the support plate 5 can also move axially with the rotation of the handle 28.

[0047] Reference Figure 6 and Figure 10 The pre-compression board force adjustment mechanism includes a second handle 41, a third screw 42, a moving block 43, an adjusting component 44, a second spring 45, a third spring 46, and two limiting components 47. The moving block 43 is mounted on the surface of the slide 56. The moving block 43 is internally connected to the third screw 42. The top of the third screw 42 is connected to the second handle 41.

The surface of the screw 42 is located at the bottom of the limiting part 47 and the spring 46 is provided. When the amount of chipping of the edge banding tape is adjusted, turn the handle 41 to move the screw 42 down a small distance. This distance is the preload. At this time, the outer diameter of the contour disc 39 should be lower than the surface of the wooden board. The handle 41 is equipped with a set screw 52 to prevent the threaded connection of the handle from loosening.

[0048] Reference Figure 9 The pre-compression board force adjustment mechanism includes a connector 49, a nut 50, a spring 51, and a screw 61.

The screw 61 is connected to the top of the sliding block 34 located below. When the amount of chipping of the edge banding tape is adjusted, the screw 61 is turned to move the screw 61 upward a small distance. This distance is the pre-compression amount. At this time, the outer diameter of the conforming disc 39 should be lower than the surface of the board.

[0049] Reference Figure 7 The template position adjustment mechanism includes a mounting strip 35, a positioning template 36, a rotating shaft 37, and an eccentric wheel 57. The mounting strip 35 is connected to the rear side of the inclined template 7. The rotating shaft 37 is connected to one side of the bottom end of the mounting strip 35. The positioning template 36 is connected to one end of the rotating shaft 37. The eccentric wheel 57 is installed at one end of the positioning template 36, and one end of the eccentric wheel 57 is connected to the mounting strip 35. When the eccentric wheel 57 is rotated, its eccentric part can drive the positioning template 36 to swing around the rotating shaft 37, so that fine adjustment between the edge of the inclined template 7 and the edge of the positioning template 36 can be achieved.

[0050] Working Principle: In the edge banding R-angle adjustment mechanism, the inclined wheel 7 is pressed against the end face of the wooden board. The finishing cutter 58 cuts the R-angle of the edge banding on the wooden board. The finishing cutter 58 is fixed. If the inclined wheel 7 moves to the right, it is equivalent to the wooden board moving closer to the finishing cutter 58, and the more edge banding is cut, the larger the R-angle becomes. Conversely, if the inclined wheel 7 moves to the left, the R-angle becomes smaller. The left and right movement of the inclined wheel 7 in this mechanism is controlled by the servo motor 1, which can achieve digital and intelligent control. The linear guide of the mounting bracket 3 is not limited to a linear guide rail. The left and right movement of the mounting bracket 3 is achieved by the ball screw 2 and the servo motor 1 together, which can achieve precise digital and intelligent control. The R-angle adjustment method of this mechanism is not limited to the servo motor 1; manual adjustment or other methods are also possible. Both are acceptable; in the edge banding chip amount adjustment mechanism, the contour disc 39 is stationary, and the finishing blade 58 needs to be adjusted to a suitable angle relative to the wooden board for chip R angle. The chip amount of the edge banding is achieved by adjusting the displacement of the finishing blade 58 in the X and Y directions. When the nut on cylinder 10 is turned, screw 12 also rotates, generating axial thrust. Since screw 12 is axially fixed, the axial force will cause mounting plate 14 to move along the axis of guide rod 25. Because the finishing blade 58 is connected to the drive motor 21, the finishing blade 58 also moves along the axis of guide rod 25. This movement direction is the Y-axis movement direction. After screw 4 is rotated, it will generate axial thrust. Mounting plate 14 cannot move. The thrust can only move the parts connected to screw 4 54 along the axis of guide rod 3 23. This movement direction is the X-axis movement. The finishing cutter 58 clears a distance at the normal chip position to allow the board to pass. The Y-axis retraction method is as follows: Compressed air is introduced into the bottom of cylinder 10. Cylinder 10 retracts, causing mounting plate 14 to rise, thus achieving Y-axis retraction. The X-axis retraction method is as follows: Compressed air is introduced into the top of the piston rod of cylinder 20. Since the piston rod is fixed on connecting block 3 24 and cannot move axially, the air force causes the cylinder body to move backward, thus achieving X-axis retraction. The position of the contour disc 39 remains unchanged. The amount of chipping of the edge banding is adjusted by adjusting the X and Y axes of the finishing cutter 58. The movement of the finishing tool 58 in the X and Y directions is achieved by rotating the piston rod of the cylinder. The power source for the online retraction of the finishing tool 58 is not limited to cylinders or motors. In the tool setting mechanism for adjusting the angle, two T-shaped connecting studs 26 are inserted into the T-shaped groove of the support plate 5. After being inserted, they cannot be removed axially. The motor mounting seat 25 is inserted into the T-shaped connecting studs 26 and locked by the hexagonal support 27 and nut respectively. When the mounting seat 25 is locked, the mounting seat 25 is fixed. When the mounting seat 25 is loosened, the mounting seat 25 can slide along the T-shaped groove. When angle adjustment is required during the tool setting process, the hexagonal support 27 and nut are loosened, the mounting seat 25 is adjusted to the appropriate angle position, and then the hexagonal support 27 and nut are locked to complete the angle tool setting work.In the edge banding thickness adjustment mechanism, since the sliding block 34 cannot move axially, and the mounting plate 60 is connected to it via the connecting rod 30, the mounting plate 60 also cannot move axially. Turning the handle 28 causes the screw 33 to move axially back and forth under the force of the thread, as the handle 28 is connected to the screw 33 via an internal thread. Since the screw 33 is locked onto the support plate 5, the support plate 5 can also move axially with the rotation of the handle 28. The positions of the finishing tool 58, the inclined wheel 7, and the wooden board are adjusted. After the section is completed, the surface of the inclined wheel 7 is only in contact with the side of the wooden board, and there is no lateral force pressing down on the board. In this state, trimming may result in the inclined wheel 7 not being in contact with the side of the board, affecting the trimming effect. Turning handle 28 causes screw 33 to extend outward a certain distance. Since screw 33 is connected to support plate 5, support plate 5 also extends outward by the same distance. Because support plate 5 is part of the edge banding R-angle adjustment mechanism, this mechanism also extends outward by the same distance. This distance is the additional pressure of spring 31. The force generated by the compression is the force of the inclined wheel 7 pressing against the side of the wooden board. This ensures that the inclined wheel 7 keeps pressing against the wooden board as it moves, guaranteeing the quality of the trimming. The pressure can be adjusted by turning the adjusting nut 32 to change the compression of the spring 31. The adjustment power of this method can be manual or servo-controlled. Compressed air is introduced into the bottom of the piston rod at the mounting plate 2 60. The direction of the force generated is opposite to the direction of the force of the spring 31. When this force is greater than the spring force, the handle 28 moves to the right a certain distance. This movement, excluding the pre-pressure, is the movement of the inclined wheel 7 away from the side of the wooden board, thus realizing the online exit function. When the compressed air at the bottom of the piston rod is removed, the inclined wheel 7 returns to its original position under the action of the spring force. The pre-pressure and edge banding thickness are adjusted by pushing the edge banding R-angle adjustment mechanism forward or backward using the thread. The pre-pressure is adjusted by adjusting the adjusting nut 32. The movement of the edge banding R-angle adjustment mechanism can be completed manually, and the movement amount is calculated from the reading of the position digital display 29. The movement amount can be completed by servo control.In the template position adjustment mechanism, because the inclined wheel 7 has a preload, it protrudes forward before the wooden board arrives and only pushes it back after the board arrives. If the preload movement exceeds the guide range of the inclined wheel 7's guide angle, the wooden board will hit the inclined wheel 7 and damage the equipment. Generally, the guide angle of the inclined wheel 7 cannot be too large, as this will reduce the axial retraction force of the inclined wheel 7. The solution to this problem is to add a positioning template 36, using the guide angle of the positioning template 36 to eliminate part of the preload, leaving... A smaller preload is guided by the inclined wheel 7. The method described above determines that the edges of the inclined wheel 7 and the positioning mold 36 are not on the same plane; the edge of the inclined wheel 7 is higher than the edge of the positioning mold 36. The rotating shaft 37 is inserted into the corresponding hole of the positioning mold 36, and the threaded part of the rotating shaft 37 is screwed into the threaded hole of the mounting strip 35 for fixation. The positioning mold 36 can rotate around the rotating shaft 37. The eccentric part of the eccentric wheel 57 is inserted into the elongated hole of the positioning mold 36, and the cylindrical part is inserted into the mounting strip 35. Then, it is locked with a nut. On the mounting strip 35, rotating the eccentric wheel 57 causes its eccentric portion to drive the positioning template 36 to swing around the rotation axis 37, thus enabling fine-tuning between the inclined wheel 7 and the edge of the positioning template 36. Adjusting the position of the contour disc 39 so that it is close to the chip removal cover 38, with the gap between them being as small as possible, ideally without touching the chip removal cover 38, ensures that the small gap prevents chips from easily flying out from around the chip removal cover 38. The contour disc 39 and the chip removal cover 38 surround the finishing cutter 58, leaving only a gap at the edge-cutting area for easy chip removal. Air enters from here and exits through the round hole of the chip hood 38, so the chips are discharged in a directional manner along the chip hood 38. The chip hood 38 is made of metal and is connected to the frame through other parts, so static electricity does not easily accumulate on it. During chip removal, the chips will not be attracted to it due to its own static electricity. The harm of static electricity attracting chips is that if the chips are not discharged in time, if they fall onto the wooden board and are pressed by the copying disc 39, the copying disc 39 will be raised, which will make the edge banding tape uneven.Method 1 for adjusting the pre-compression force of the profile disc 39 on the wooden board: The limiting part 47 is fixed to the screw 42. A spring 45 is located on the upper surface of the limiting part 47. Because the limiting part 47 is fixed, the spring force of the spring 45 supports the weight of the remaining components, and the gravity and spring force are basically balanced. With the amount of edge banding chips adjusted, turn the handle 41 to move the screw 42 downwards a small distance. This distance is the pre-compression amount. At this time, the outer diameter of the profile disc 39 should be lower than the surface of the wooden board. Pre-compression force adjustment: Turn the adjusting part 44 to move it downwards; the pre-compression force will then be adjusted accordingly. The pressure will increase if the pressure increases and decrease if it decreases. Method two for adjusting the pre-pressure of the wood board using the contour disc 39: With the edge banding chip amount adjusted, turn screw 561 upwards a small distance; this distance is the pre-pressure amount. At this time, the outer diameter of the contour disc 39 should be lower than the surface of the wood board. Pre-pressure adjustment: Turn nut 250 downwards. If nut 250 moves downwards, the pre-pressure will increase; conversely, it will decrease. In the quick-release mechanism of the chip module, the function of this mechanism is to facilitate the installation and removal of the edge banding chip amount adjustment mechanism from the tool setting mechanism. Simply release spring 559. Move the locking shaft 11 to the large round hole, and it can be pulled out directly. Insert the locking shaft 11 into the corresponding round hole of the upper connecting plate 16. The two ends of the spring 59 are respectively close to the bottom of the round hole of the upper connecting plate 16, and the other end is close to the stepped end face of the locking shaft 11. The elastic force of the spring 59 causes the locking shaft 11 to move outward, but the amount of movement is limited by the nut 40. During installation, insert the locking shaft 11 into the large round hole, then push it so that the buckle engages with the buckling surface. Finally, tighten the nut 40. Due to the action of the spring 59, the nut 40 is loosened, allowing the locking shaft 11 to move out slightly. This design ensures that the locking mechanism and the locking surface are separated by a certain distance, preventing jamming during installation. Due to the action of spring 59, the locking shaft 11 does not retract and jam the edge of the locking surface during installation, making the installation process smoother. In the handle's anti-loosening structure, the handle's center hole is a threaded hole. Screwing it onto the rod's external thread allows the rod to rotate. However, if the rotational resistance of the rod exceeds the thread's locking force, the handle's threaded connection will loosen. Adding and tightening the set screw 52 on the handle increases the thread's locking force, effectively solving the above problem and preventing the handle's threaded connection from loosening.
