Description
Technical Field
[0001] The present invention relates to the technical field of wood processing, and specifically to a burr treatment device for a wood board after cutting. Background Technique
[0002] The burrs generated after cutting the wood board are usually irregular and rough, which will seriously affect the overall aesthetics of the wood board. Especially in occasions where the appearance requirements of the wood board are relatively high, such as furniture making, decorative materials, etc., the untreated burrs will appear very obtrusive, reducing the overall texture and visual effect of the product. The existence of burrs not only affects the aesthetics but may also reduce the durability of the wood board. The burrs are easy to hook clothes, skin, etc., resulting in wear or tearing. At the same time, it is easier for dust and dirt to accumulate at the burrs and it is difficult to clean. Over time, it may cause stains or corrosion on the surface of the wood board. Therefore, the burrs of the wood board usually need to be treated after cutting; During the process of treating the burrs of the wood board, the staff places the wood board on the conveying mechanism, and conveys the wood board to the burr grinding machine through the conveying mechanism, and uses the burr grinding machine to perform burr grinding treatment on the cutting edge of the board. During the grinding process, the board is limited by the pressure roller. Among them, when treating wood boards with relatively low hardness such as pine and poplar, due to their soft texture, they are prone to excessive wear during the burr treatment process because they are relatively close to the grinding tool. Therefore, it is necessary to pay attention to the distance between the grinding tool and the soft wood board to prevent scratches, depressions or damages on the soft wood board due to excessive wear. However, in the existing burr treatment process, due to different products made of wood boards, the wood boards will be cut into different sizes. Therefore, when treating burrs of different batches of wood boards, it is necessary to adjust the position of the grinding tool according to the size of the wood board to avoid the occurrence of excessive wear. However, to adjust the position of the grinding tool, the staff needs to measure the size of each batch of wood boards, and then adjust the position of the grinding tool after obtaining the results. The operation is cumbersome and inefficient. For this reason, we propose a burr treatment device for a wood board after cutting. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention uses the distance measuring part to detect the size of the sawn wood board, and controls the position adjustment of the grinding mechanism according to the detection result. Therefore, when the grinding mechanism grinds the wood board, the situation of over-grinding can be effectively avoided. By detecting the positional relationship between the detection rod frame and the wood board, the detection rod frame can move synchronously with the wood board, and measure the size of the wood board during the movement. At the same time, when there are arc-shaped, concave and other areas on the wood board, the detection rod frame is still in contact with the wood board under the action of the return spring, that is, the measured value of the distance measuring element will change. The subsequent position adjustment of the grinding mechanism can be effectively controlled through the detected data to improve the quality of burr removal. In the present invention, a servo motor is used to engage a worm and worm gear mechanism. An electromagnet body drives a magnetic shaft to rotate, thereby causing the magnetic shaft to drive a rotating sleeve to rotate on the side wall of a support frame. The rotating sleeve drives a lead screw to rotate, and further drives a frame to control the position adjustment of a grinding mechanism under the action of the lead screw. Moreover, the grinding mechanism can be adjusted separately according to specific usage conditions, so as to effectively remove the burrs of the cut wooden board and reduce the occurrence probability of scratches, depressions or damages and other conditions.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0018] Please refer to Figures 1-12, the present invention provides a technical solution: a deburring device for the rough edges of wood-based panels. The present invention makes corresponding improvements to the technical problems in the background art, including a first conveying mechanism 1 and a second conveying mechanism 2 located on one side of the first conveying mechanism 1. A pressing roller mechanism 3 is provided between the first conveying mechanism 1 and the second conveying mechanism 2. A bracket 4 is fixedly installed on the pressing roller mechanism 3, and a support frame 41 is fixedly installed on the bracket 4. A power mechanism 5 is arranged inside the support frame 41, and lead screws 42 connected to the power mechanism 5 are symmetrically arranged on both sides of the support frame 41. A driving frame 43 slidably connected to the inner wall of the bracket 4 is installed on the lead screw 42, and a grinding mechanism 44 is installed on the driving frame 43. The power mechanism 5 rotates the lead screw 42, and the driving frame 43 controls the position adjustment of the grinding mechanism 44 under the action of the lead screw 42; As a further limitation in the present invention, the power mechanism 5 includes a worm 51 arranged inside the support frame 41 and rotatably connected to its inner wall. A servo motor 52 is fixedly installed on the outer wall of the support frame 41, and the output end of the servo motor 52 is fixedly connected to one end of the worm 51. A worm gear mechanism 53 meshing with the worm 51 is arranged inside the support frame 41. The worm gear mechanism 53 is rotatably connected to the inner wall of the support frame 41. Electromagnet bodies 54 are fixedly installed at both ends of the worm gear mechanism 53. Rotating sleeves 55 are rotatably installed on both sides of the support frame 41, and the rotating sleeves 55 are fixedly connected to the ends of the lead screws 42. A magnetic shaft body 56 slidably connected to its inner wall is installed inside the rotating sleeve 55. The magnetic shaft body 56 is located on one side of the electromagnet body 54, and the electromagnet body 54 generates an attractive force on the magnetic shaft body 56 when energized. A spring body 57 is connected between the magnetic shaft body 56 and the inner wall of the rotating sleeve 55; Combined with the attached Figure 1 As shown, the wooden board is first placed on the first conveying mechanism 1. Under the action of the first conveying mechanism 1, the wooden board moves towards the pressing roller mechanism 3. When a local area of the wooden board moves to the pressing roller mechanism 3, the pressing roller mechanism 3 limits the wooden board, and the first conveying mechanism 1 continues to convey the wooden board. Before that, the position of the grinding mechanisms 44 located on both sides of the wooden board can be automatically adjusted. The specific operation is as follows: Combined with the attached Figures 9-11As shown in the figure, first, the electromagnet bodies 54 at both ends of the worm gear mechanism 53 are energized. Subsequently, under the action of the servo motor 52 driving the worm 51, the worm gear mechanism 53 is engaged, and the electromagnet body 54 drives the magnetic shaft body 56 to rotate. Since the magnetic shaft body 56 is slidably connected to the rotating sleeve 55, the magnetic shaft body 56 drives the rotating sleeve 55 to rotate on the side wall of the support frame 41. The rotating sleeve 55 drives the lead screw 42 to rotate, and then drives the frame 43 to control the position adjustment of the grinding mechanism 44 under the action of the lead screw 42. As mentioned above, since the grinding mechanisms 44 are provided on both sides of the wooden board, the distances between the wooden board and the grinding mechanisms 44 are different. Therefore, the position can be adjusted separately according to the distance between one side of the wooden board and the corresponding grinding mechanism 44. For example: when one side of the wooden board is far from the corresponding grinding mechanism 44 and the other side is close to the corresponding grinding mechanism 44, first, the electromagnet bodies 54 at both ends of the worm gear mechanism 53 are energized, so that the other side of the wooden board and the corresponding grinding mechanism 44 move to an appropriate grinding position (a position where the side wall of the wooden board can be ground but excessive wear is not likely to occur). Subsequently, the electromagnet body 54 corresponding to the other side of the wooden board is powered off, and the electromagnet body 54 corresponding to one side of the wooden board remains energized, so that the grinding mechanism 44 corresponding to one side of the wooden board continues to move and finally moves to a suitable position to grind the side wall of the wooden board; In order to facilitate the position adjustment of the grinding mechanism 44 according to the size of the wooden board, the present invention adopts a corresponding design to monitor the size of the cut wooden board. The specific design is as follows: Combined with the attached Figures 2-4As shown in the figure, limiting frames 6 are fixedly installed on both sides of the conveying mechanism 1, and sliding grooves 61 are provided on both sides of the limiting frames 6. A limiting sleeve 62 that is limited in movement within the sliding groove 61 is installed on the limiting frame 6, and a distance measuring part 7 for measuring the size of the wooden board is further provided on the limiting sleeve 62. As a further limitation in the present invention, the distance measuring part 7 includes a connecting rod frame 71 that is slidably connected to the inner wall of the limiting sleeve 62, and a detection rod frame 72 is fixedly installed at one end of the connecting rod frame 71 located outside the limiting sleeve 62. In the initial state (i.e., when the wooden board is just placed on the conveying mechanism 1), the detection rod frame 72 is located on the movement track of the wooden board. A distance measuring element 73 is fixedly installed on one side of each detection rod frame 72 close to the conveying mechanism 1. A force-bearing magnetic plate 74 is also fixedly installed on the detection rod frame 72. Openings 1001 are provided on both sides of the conveying mechanism 1. A sliding sleeve 75 that is slidably connected to its inner wall is installed inside the opening 1001. The sliding sleeve 75 is rotatably connected to the limiting sleeve 62. A force-applying magnetic plate 76 is fixedly installed at one end of the sliding sleeve 75 close to the detection rod frame 72. The force-applying magnetic plate 76 and the force-bearing magnetic plate 74 have opposite magnetic poles. The force-applying magnetic plate 76 is located on the movement track of the force-bearing magnetic plate 74. A return spring 77 is connected between the connecting rod frame 71 and the inner wall of the limiting sleeve 62; a constant force spring 66 is connected between the moving frame 63 and the inner wall of the limiting frame 6. A baffle 751 is fixedly installed on the sliding sleeve 75, and a fixed rod frame 752 is fixedly installed on the outer wall of the limiting sleeve 62. The baffle 751 is located on the movement track of the fixed rod frame 752; Combined with the attached Figures 5-8As shown in the figure, a moving frame 63 is installed inside the limit frame 6 and is slidably connected to its inner wall. The limit sleeve 62 is rotatably connected to the side wall of the moving frame 63. A cam 64 is fixedly installed on the limit sleeve 62. The cam 64 is located inside the moving frame 63. A torsion spring 65 is connected between the limit sleeve 62 and the side wall of the moving frame 63. A roller mechanism 68 is arranged inside the moving frame 63. The roller mechanism 68 is in contact with the cam 64. A working shaft body 69 is fixedly installed at the bottom of the roller mechanism 68. One end of the working shaft body 69 penetrates through the bottom of the moving frame 63 and extends to the outside. A limit plate frame 60 is fixedly installed at the end of the working shaft body 69. A buffer spring 67 is connected between the roller mechanism 68 and the inner wall of the moving frame 63. A fixed frame 8 is fixedly installed inside the limit frame 6. A magnetic panel 81 is arranged inside the fixed frame 8. Moving shaft bodies 82 are fixedly installed at both ends of the magnetic panel 81. Slide blocks 83 are installed on both sides of the fixed frame 8 and are slidably connected to its inner wall. The moving shaft bodies 82 are slidably connected to the slide blocks 83. A plastic spring 84 sleeved on the moving shaft bodies 82 is connected between the slide blocks 83 and the ends of the magnetic panel 81. A plastic spring 85 is also connected between the slide blocks 83 and the bottom of the fixed frame 8. A plurality of electric magnetic groups 86 are fixedly installed at the bottom of the fixed frame 8. When the electric magnetic groups 86 are energized, a repulsive force is generated on the magnetic panel 81. A plurality of clamping plate frames 87 are fixedly installed on the magnetic panel 81. It should be noted that in the initial state (i.e., when the wooden board is just placed on the conveying mechanism 1), the limit plate frame 60 is located between the clamping plate frames 87. Combined with the attached Figure 7 As shown in the figure, the contact parts between the limit plate frame 60 and the clamping plate frames 87 are all triangular. The space between the clamping plate frames 87 is adapted to the limit plate frame 60. When the limit plate frame 60 is located between the clamping plate frames 87, it will be blocked by the clamping plate frames 87. Thus, the limit plate frame 60 is in a limited state, and at this time, the moving frame 63 is also in a limited state; The size of the cut wooden board is monitored. The specific operation is as follows: Combined with the attached Figures 2-4 As shown in the figure, in the initial state (i.e., when the wooden board is just placed on the conveying mechanism 1), the detection rod frame 72 is located on the movement track of the wooden board. As the wooden board moves, the detection rod frame 72 will contact the wooden board and be affected by the force of the wooden board. Since in the initial state, the limit plate frame 60 is located between the clamping plate frames 87 (as shown in the attached Figure 7As shown, at this time, the limit plate frame 60 is limited. Furthermore, the acting shaft body 69 connected to the limit plate frame 60 will also be limited, resulting in the limitation of the moving frame 63, the limit sleeve 62, the connecting rod frame 71, and other components thereon. It should be noted that the outer wall of the detection rod frame 72 in the present invention can be wrapped with a soft material (such as silica gel). Thus, when the wooden board acts on the detection rod frame 72, the detection rod frame 72 will rotate. When the detection rod frame 72 rotates, since the connecting rod frame 71 is slidably connected to the limit sleeve 62, the limit sleeve 62 will rotate synchronously with it. Referring to the attached Figure 4 As shown, when the detection rod frame 72 rotates, the force-bearing magnetic plate 74 on the detection rod frame 72 will rotate towards the corresponding position of the force-applying magnetic plate 76 (on the sliding sleeve 75), and the fixed rod frame 752 on the limit sleeve 62 will rotate towards the baffle 751. When the force-bearing magnetic plate 74 rotates to the corresponding position of the force-applying magnetic plate 76, at this time, the fixed rod frame 752 also rotates to the corresponding position of the baffle 751, and the detection rod frame 72 is still on the movement trajectory of the wooden board; Referring to the attached Figure 5 As shown, when the fixed rod frame 752 on the limit sleeve 62 rotates to the corresponding position of the sliding sleeve 75, since the limit sleeve 62 is rotatably connected to the sliding sleeve 75, and the sliding sleeve 75 only performs limited sliding in the slot 1001 (i.e., the sliding sleeve 75 does not rotate in the slot 1001), when the fixed rod frame 752 moves to the position of the baffle 751, it will be blocked by the baffle 751, and the force-bearing magnetic plate 74 also moves to the force-applying magnetic plate 76. The force-applying magnetic plate 76 generates an attractive force on the force-bearing magnetic plate 74, so that the force-bearing magnetic plate 74 is subjected to the attractive force of the force-applying magnetic plate 76. Furthermore, the force-bearing magnetic plate 74 drives the detection rod frame 72 to move the connecting rod frame 71 into the limit sleeve 62. Since the detection rod frame 72 is still on the movement trajectory of the wooden board, the movement trajectory of the detection rod frame 72 at this time is as follows: Under the action of the force-bearing magnetic plate 74, the detection rod frame 72 causes the connecting rod frame 71 to slide in the limit sleeve 62, and the connecting rod frame 71 squeezes the return spring 77 during the movement. Since the detection rod frame 72 is on the movement trajectory of the wooden board, the detection rod frame 72 is subjected to a force, causing the connecting rod frame 71 to drive the limit sleeve 62 to perform a limited movement in the chute 61. The sliding sleeve 75 rotatably connected to the limit sleeve 62 will perform a limited sliding in the slot 1001. Thus, in this state, the detection rod frame 72 will move towards the inside of the limit sleeve 62 while moving synchronously with the wooden board, and the distance measuring element 73 on the detection rod frame 72 will move towards the side wall of the conveying mechanism 1. During the movement of the limit sleeve 62, it will drive the moving frame 63 to perform a limited sliding in the limit frame 6. During the limited movement of the moving frame 63 in the limit frame 6, the moving frame 63 stretches the constant force spring 66; As described above, when the limiting sleeve 62 rotates, the cam 64 on the limiting sleeve 62 will rotate synchronously with it. Referring to the attached Figure 7 figure, when the fixed rod holder 752 on the limiting sleeve 62 rotates to the corresponding position of the baffle 751, the convex part of the cam 64 will leave the roller mechanism 68 at this time. The roller mechanism 68 moves upward under the action of the buffer spring 67, and then the limiting plate holder 60 on the acting shaft body 69 will leave between the clamping plate holders 87, that is, the clamping plate holders 87 no longer limit the limiting plate holder 60, so that the acting shaft body 69, the moving frame 63, the limiting sleeve 62, the connecting rod holder 71, the detection rod holder 72 and the mechanical components on it are all released from the limit, so that the detection rod holder 72 can move synchronously with the wooden board. It should be noted that when the limiting sleeve 62 rotates, the torsion spring 65 is in a deformed state; When the detection rod holder 72 contracts into the limiting sleeve 62 under the action of the connecting rod holder 71, the detection rod holder 72 gradually moves away from the movement track of the wooden board. When the detection rod holder 72 is no longer on the movement track of the wooden board, the limiting sleeve 62 rotates and resets under the action of the deformed torsion spring 65 at this time, so that the force-receiving magnetic plate 74 on the detection rod holder 72 leaves the corresponding position of the force-applying magnetic plate 76, that is, the detection rod holder 72 no longer moves into the limiting sleeve 62. Under the action of the reset spring 77, the connecting rod holder 71 drives the detection rod holder 72 to perform a reset movement, and at this time, the detection rod holder 72 will contact the side wall of the wooden board during the movement. Furthermore, the distance measuring element 73 on the detection rod holder 72 measures the distance from the conveying mechanism 1 at this time. The position of the grinding mechanism 44 can be effectively controlled through the measured result. When the limiting sleeve 62 is reset, the cam 64 will apply a force to the roller mechanism 68, and the acting shaft body 69 on the roller mechanism 68 will drive the limiting plate holder 60 to move between the clamping plate holders 87. Since the contact surfaces between the limiting plate holder 60 and the clamping plate holders 87 are all triangular, when the limiting plate holder 60 contacts the side wall of the clamping plate holder 87 during the descending process, the clamping plate holder 87 will drive the magnetic panel 81 to move under the action of the force. The moving shaft body 82 on the magnetic panel 81 will perform a directional movement in the sliding block 83, and both ends of the magnetic panel 81 will squeeze or stretch the plastic spring 84. It should be noted that the electric magnetic group 86 at the bottom of the fixed frame 8 is always in an energized state, so the magnetic panel 81 is always subject to a repulsive force, and the plastic spring 85 connecting the sliding block 83 and the bottom of the fixed frame 8 is in a stretched state; when the limiting plate holder 60 is between the clamping plate holders 87, the limiting plate holder 60 is in a limited state at this time. Furthermore, when the detection rod holder 72 contacts the side wall of the wooden board, the detection rod holder 72 will not be displaced due to excessive friction. Referring to the attached Figure 6As shown, a sphere is also installed on the contact surface between the detection rod holder 72 and the side wall of the wooden board. The sphere can effectively reduce the friction between the wooden board and the detection rod holder 72. At the same time, when the wooden board is in an arc, concave or other areas, the detection rod holder 72 remains in contact with the wooden board under the action of the return spring 77. That is, the measured value of the distance measuring element 73 will change. The subsequent position adjustment of the grinding mechanism 44 can be effectively controlled through the detected data; When the wooden board is detected, the return spring 77 acts on the connecting rod holder 71, causing the connecting rod holder 71 to drive the detection rod holder 72 to reset. At the same time, the electromagnetic group 86 is powered off. Under the action of the plastic spring two 85, the magnetic panel 81 moves downward under the action of the sliding block 83, and the clamping plate holder 87 on the magnetic panel 81 will move downward synchronously with it. Then, at this time, the clamping plate holder 87 no longer acts on the limiting plate holder 60, that is, the moving frame 63 is no longer limited and moves towards the initial position under the action of the constant force spring 66. When the moving frame 63 returns to the initial position, the electromagnetic group 86 is powered on again, the magnetic panel 81 moves upward, and the clamping plate holder 87 continues to limit the limiting plate holder 60, so as to detect the next wooden board; The present invention also fixedly installs connection frames 9 on both sides of the conveying mechanism two 2. A sliding frame 91 slidably connected to its inner wall is installed inside the connection frame 9. A silica gel part 92 is installed in parallel inside the sliding frame 91 and is limitedly slidable inside the sliding frame 91. A touch shaft body 93 is fixedly installed on one side of the silica gel part 92. Induction elements 94 are installed in parallel on the inner wall of the sliding frame 91. An elastic sheet 95 installed on the inner wall of the sliding frame 91 is arranged between the induction element 94 and the touch shaft body 93. It should be noted that the touch shaft body 93 is in contact with the elastic sheet 95, and the induction element 94 is relatively close to the elastic sheet 95. There is a frictional force between the silica gel part 92 and the sliding frame 91, but the frictional force is small. If there are burrs adhered to the surface of the polished wooden board, they will fall off from the side wall of the wooden board under the action of the silica gel part 92. If there are still many burrs on the surface of the wooden board, that is, the side wall of the wooden board has a certain frictional force, then when the wooden board contacts the silica gel part 92, the silica gel part 92 will move under the frictional action of the side wall of the wooden board. That is, the touch shaft body 93 on the silica gel part 92 will act on the elastic sheet 95, and the elastic sheet 95 will slightly deform to contact the induction element 94. The induction element 94 receives the signal to inform the staff to detect the side wall of the wooden board, so as to improve the quality of removing the burrs of the wooden board. A block-shaped electromagnetic group 96 is fixedly installed on the inner wall of the connection frame 9. One side of the sliding frame 91 close to the block-shaped electromagnetic group 96 is a magnetic surface. The block-shaped electromagnetic group 96 is powered on to generate a magnetic force on the magnetic surface of the sliding frame 91. By changing the current direction of the block-shaped electromagnetic group 96 to change the magnetism, the position of the sliding frame 91 is controlled to adapt to wooden boards of different sizes for burr treatment.
