Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of sanding machines, and particularly to a surface sanding treatment device for artificial boards. Background Art
[0002] After the artificial board is hot-pressed and formed, the surface often has defects such as unevenness, burrs, and pre-cured layers. These defects not only affect the appearance but may also cause problems such as a decrease in the adhesion of the coating and a shortening of the product service life. Therefore, it is necessary to use a sanding machine to sand the artificial board.
[0003] At present, when the sanding machine is used to sand the artificial board, the artificial board is directly placed on the conveyor belt, and then the conveyor belt drives the artificial board to move under the sanding belt for sanding. However, since the artificial board has no limiting structure, it is very easy to shift when the conveyor belt drives it to move. If the shift is too large, it may get stuck in the sanding cover, affecting normal use and easily causing damage to the sanding machine. Moreover, in order to facilitate the movement of the artificial board, both sides of the sanding cover are usually directly open, and a large amount of debris and dust are generated during the processing. At this time, the debris and dust are easily scattered outwards, affecting environmental hygiene and the health of workers. Summary of the Invention
[0004] The present invention provides a surface sanding treatment device for artificial boards, in which debris and dust are not easily scattered outwards from the relatively small openings on both sides during the processing, ensuring environmental hygiene and the health of workers, and capable of avoiding the shift of the artificial board during the processing, ensuring normal use, and at the same time avoiding damage to the sanding machine.
[0005] In the first aspect of the present invention, a surface sanding treatment device for artificial boards is provided, which specifically includes: a main support base; An artificial board conveyor belt is rotatably installed inside the top of the main support base, and a sanding cover is installed at the middle position of the top of the main support base; a plurality of first retaining bars are slidably installed on the left side of the sanding cover, and a plurality of second retaining bars are slidably installed on the right side of the sanding cover. Elastic bands are fixed to both the left and right sides of the top of the sanding cover; a maintenance top cover is installed on the top of the sanding cover, a dust suction pipe is provided at the middle position of the maintenance top cover, and a sanding belt is rotatably installed inside the sanding cover; a plurality of artificial board pressing rollers are rotatably installed on the top of the main support base, two limiting rings are slidably installed on the outside of each artificial board pressing roller, a rack is fixed to one side of each limiting ring, and a gear is rotatably installed at the middle position inside each artificial board pressing roller.
[0006] Wherein, the diameter of the limiting ring is twice the diameter of the artificial board pressing roller, and the inner diameter of the middle circular hole of the limiting ring is equal to the outer diameter of the artificial board pressing roller.
[0007] Among them, a cylindrical block and two rectangular plates are provided on the inner side of the limiting ring. A cylindrical groove is provided on the inner side of each wood-based panel pressing roller, and two open grooves are provided on the outer wall of the wood-based panel pressing roller. The cylindrical block and the rectangular plates on the inner side of the limiting ring can slide back and forth in the cylindrical groove on the inner side of the wood-based panel pressing roller and in the open grooves on the outer wall of the wood-based panel pressing roller respectively.
[0008] Among them, a vertical T-shaped raised strip is provided on the right side of the first retaining bar and the left side of the second retaining bar, and corresponding T-shaped guide grooves are also provided on the left and right sides of the top of the sanding cover. When the first retaining bar and the second retaining bar slide down to the bottommost position, their bottom surfaces will be in close contact with the top surface of the wood-based panel conveyor belt.
[0009] Among them, the gear is located at the middle position of the cylindrical groove on the inner side of the wood-based panel pressing roller. The tooth grooves on the rack on one side of the limiting ring are all engaged with the gear, and the two limiting rings on the outer side of the wood-based panel pressing roller are symmetrically arranged front and back with the middle position of the wood-based panel pressing roller as the reference.
[0010] Among them, the first retaining bar and the second retaining bar are both solid metal bars, and the adjacent first retaining bar and second retaining bar are in close contact with each other. The front and rear ends of the elastic band are fixed to the top of the sanding cover, and the middle part of the elastic band covers the tops of the first retaining bar and the second retaining bar.
[0011] Among them, an umbrella-shaped opening is also provided on the outer wall of the limiting ring, and an internal hexagonal screw is screwed in the umbrella-shaped opening, and one end of the internal hexagonal screw will be in close contact with the outer wall of the wood-based panel pressing roller after being tightened.
[0012] Among them, an inclined surface is provided on the bottom left side of the first retaining bar and the bottom left side of the second retaining bar. The bottom surface of the sanding belt and the bottom surface of the wood-based panel pressing roller are in the same plane, and the top edge of the inclined surface on the bottom left side of the first retaining bar and the second retaining bar is above the bottom surfaces of the sanding belt and the wood-based panel pressing roller.
[0013] The present invention provides a wood-based panel surface sanding treatment device, which has the following beneficial effects: In the present invention, the sanding cover cooperates with the first retaining bar and the second retaining bar to be able to block the chips and dust generated during processing. When the wood-based panel enters and exits the sanding cover, the first retaining bar and the second retaining bar will slide upward to avoid, and after the wood-based panel is removed, the first retaining bar and the second retaining bar will automatically slide back to their positions. During the processing process, the chips and dust are not easily scattered out from both sides of the sanding cover, ensuring environmental hygiene and the health of workers.
[0014] In addition, the artificial board pressing roller can assist in conveying the artificial board on the top of the artificial board. The limit ring on the outside of the artificial board pressing roller can slide to adjust the spacing and lock it. When the artificial board conveyor belt drives the artificial board to move to the right, the limit ring can limit the forward and backward movement of the artificial board, and can adapt to artificial boards of different widths, avoiding the deviation of the artificial board during processing, ensuring normal use, and avoiding damage to the sander.

[0018] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0019] Example 1: Please refer to Figures 1 to 8 :[[]]END]] The present invention provides a surface sanding treatment device for wood-based panels, comprising: a main support base 1; Inside the top of the main support base 1, a wood-based panel conveyor belt 2 is rotatably installed. In the middle position of the top of the main support base 1, a sanding hood 3 is installed. The main support base 1 is used to support other structural parts of the device. The wood-based panel conveyor belt 2 is used to support and convey the wood-based panel. The sanding hood 3 is used to support the sanding belt 9. Moreover, when sanding the wood-based panel, the sanding hood 3 cooperates with the first baffle 4 and the second baffle 5 to block the debris and dust generated during processing. Sixteen first baffles 4 are slidably installed on the left side of the sanding hood 3, and a total of sixteen second baffles 5 are slidably installed on the right side of the sanding hood 3. On the left and right sides of the top of the sanding hood 3, a elastic band 6 is fixed. The first baffle 4 and the second baffle 5 can stably slide up and down under the support of the sanding hood 3. During the sanding process, the first baffle 4 and the second baffle 5 in contact with the wood-based panel will move up, while the first baffle 4 and the second baffle 5 not in contact with the wood-based panel will remain in close contact with the top surface of the wood-based panel conveyor belt 2. Therefore, during the sanding process, the openings on the left and right sides of the sanding hood 3 communicating with the outside will be relatively small, reducing the outward dispersion of dust. When the wood-based panel disengages from the bottom of the first baffle 4 and the second baffle 5, the first baffle 4 and the second baffle 5 can automatically slide down by gravity. At the same time, the elastic band 6 can also push the first baffle 4 and the second baffle 5 downward to assist them in returning to their positions. A maintenance top cover 7 is installed on the top of the sanding hood 3. In the middle position of the maintenance top cover 7, a dust suction pipe 8 is provided. Inside the sanding hood 3, a sanding belt 9 is also rotatably installed. When the wood-based panel moves to the right, its top surface will contact the bottom surface of the sanding belt 9 for sanding treatment. The debris and dust generated during the sanding process will be drawn outwards by the dust suction device in the workshop through the dust suction pipe 8. When the sanding belt 9 needs to be replaced, the maintenance top cover 7 can be disassembled, and then the operation can be carried out through the opening on the top of the sanding hood 3. Four wood-based panel pressing rollers 10 are rotatably installed on the top of the main support base 1. On the outside of each wood-based panel pressing roller 10, two limit rings 11 are slidably installed. On one side of each limit ring 11, a rack 12 is fixed. In the middle position of the inner side of each wood-based panel pressing roller 10, a gear 13 is also rotatably installed. When the wood-based panel is conveyed to the right, the wood-based panel pressing roller 10 can press the wood-based panel downward at the top, so as to ensure that the bottom surface of the wood-based panel is in close contact with the top surface of the wood-based panel conveyor belt 2. When sanding the wood-based panel, the front and rear spacing of the limit rings 11 on the outside of the wood-based panel pressing roller 10 can be adjusted according to the width of the wood-based panel first. When adjusting the position of the limit ring 11, one of the limit rings 11 can be pushed forward and backward for adjustment. During the adjustment process, the rack 12 on one side of this limit ring 11 will drive the gear 13 to rotate, and when the gear 13 rotates, it can drive the other limit ring 11 to move synchronously and in the opposite direction through the rack 12 on one side of the other limit ring 11. Slide the limit ring 11 to adjust the spacing to be equal to the width of the wood-based panel. When the wood-based panel conveyor belt 2 drives the wood-based panel to move to the right, the right part of the wood-based panel will first be inserted into the opening between the two limit rings 11 on the outside of the wood-based panel pressing roller 10. At this time, the limit ring 11 can limit the front and rear movement of the wood-based panel, avoiding the situation of the limit ring 11 shifting during the processing.
[0020] In this embodiment, as Figures 1 - 3 and Figure 7 shown, the diameter of the limit ring 11 is twice that of the particle board pressing roller 10, and the inner diameter of the middle round hole of the limit ring 11 is equal to the outer diameter of the particle board pressing roller 10. When sanding the particle board, the front and rear spacing of the limit ring 11 outside the particle board pressing roller 10 can be adjusted according to the width of the particle board first. Just slide the limit ring 11 to adjust the spacing to be equal to the width of the particle board. When the particle board conveyor belt 2 drives the particle board to move to the right, the right part of the particle board will first be embedded into the opening between the two limit rings 11 outside the particle board pressing roller 10. At this time, the limit ring 11 can limit the front and back movement of the particle board and avoid the situation of the limit ring 11 shifting during the processing.
[0021] In this embodiment, as Figure 7 and Figure 8 shown, a cylindrical block and two rectangular plates are provided on the inner side of the limit ring 11. A cylindrical groove is provided on the inner side of each particle board pressing roller 10, and two opening grooves are provided on the outer wall of the particle board pressing roller 10. The cylindrical block and the rectangular plates on the inner side of the limit ring 11 can slide back and forth in the cylindrical groove on the inner side of the particle board pressing roller 10 and in the opening grooves on the outer wall of the particle board pressing roller 10 respectively. When the limit ring 11 is pushed and adjusted back and forth, the cylindrical block and the rectangular plates on its inner side will also slide in the cylindrical groove on the inner side of the particle board pressing roller 10 and in the opening grooves on the outer wall of the particle board pressing roller 10, so as to ensure the stability of the limit ring 11 when sliding.
[0022] In this embodiment, as Figures 1 - 6 shown, a vertical T-shaped protruding strip is provided on the right side of the first baffle 4 and the left side of the second baffle 5. Corresponding T-shaped guide grooves are also provided on the left and right sides of the top of the sanding cover 3. When the first baffle 4 and the second baffle 5 slide down to the bottom, their bottom surfaces will be in close contact with the top surface of the particle board conveyor belt 2. The first baffle 4 and the second baffle 5 can slide up and down stably under the support of the sanding cover 3. During the sanding process, the first baffle 4 and the second baffle 5 in contact with the particle board will move up, while the first baffle 4 and the second baffle 5 not in contact with the particle board will remain in close contact with the top surface of the particle board conveyor belt 2. Therefore, during the sanding process, the openings on the left and right sides of the sanding cover 3 communicating with the outside will be relatively small, reducing the dust from spreading outwards.
[0023] In this embodiment, as Figure 7As shown, the gear 13 is located at the middle position of the inner cylindrical groove of the wood-based panel pressing roller 10. The tooth grooves on the rack 12 on one side of the limit ring 11 are all engaged with the gear 13. Moreover, the two limit rings 11 on the outer side of the wood-based panel pressing roller 10 are symmetrically arranged before and after with the middle position of the wood-based panel pressing roller 10 as the reference. When adjusting the position of the limit ring 11, one of the limit rings 11 can be pushed forward and backward for adjustment. During the adjustment process, the rack 12 on one side of this limit ring 11 will drive the gear 13 to rotate, and when the gear 13 rotates, it can drive the other limit ring 11 to displace synchronously and in the opposite direction through the rack 12 on one side of the other limit ring 11. Therefore, the distance between the two limit rings 11 can be adjusted.
[0024] In this embodiment, as Figures 1 - 6 shown, the first stop bar 4 and the second stop bar 5 are both solid metal bars, and the adjacent first stop bar 4 and second stop bar 5 are in close contact with each other. The front and rear ends of the elastic band 6 are fixed to the top of the sanding cover 3, and the middle part of the elastic band 6 covers the tops of the first stop bar 4 and the second stop bar 5. Therefore, after the wood-based panel separates from the bottoms of the first stop bar 4 and the second stop bar 5, the first stop bar 4 and the second stop bar 5 can automatically slide down by gravity, and at the same time, the elastic band 6 can also push the first stop bar 4 and the second stop bar 5 downward.
[0025] In this embodiment, as Figures 1 - 3 and Figure 5 and Figure 6 shown, an inclined surface is provided on the left side of the bottom of the first stop bar 4 and the left side of the bottom of the second stop bar 5. The bottom surface of the sanding belt 9 and the bottom surface of the wood-based panel pressing roller 10 are in the same plane. The top edges of the inclined surfaces on the left side of the bottoms of the first stop bar 4 and the second stop bar 5 are above the bottom surfaces of the sanding belt 9 and the wood-based panel pressing roller 10. When the wood-based panel moves to the right, its right end will contact the inclined surface on the left side of the bottom of the first stop bar 4. At this time, the wood-based panel can push the first stop bar 4 it can contact upward. Finally, the bottom surface of the first stop bar 4 after upward sliding will be in close contact with the top surface of the wood-based panel. Subsequently, the top surface of the wood-based panel will contact the bottom surface of the sanding belt 9 for sanding treatment. During the treatment process, the wood-based panel will continue to move to the right, and then the right end of the wood-based panel will contact the inclined surface on the left side of the bottom of the second stop bar 5. At this time, the wood-based panel can push the second stop bar 5 it can contact upward. Finally, the bottom surface of the second stop bar 5 after upward sliding will also be in close contact with the top surface of the wood-based panel. Therefore, during the sanding process, the openings on the left and right sides of the sanding cover 3 communicating with the outside will be relatively small, reducing the dust from spreading outwards.
[0026] Embodiment 2, on the basis of Embodiment 1, as Figures 1 - 8As shown, an umbrella-shaped opening is also provided on the outer wall of the limit ring 11. An internal hexagonal screw is screwed in the umbrella-shaped opening through threads. After the internal hexagonal screw is tightened, one end of it will be in close contact with the outer wall of the wood-based panel roller 10. When sanding the wood-based panel, first adjust the front and rear spacing of the limit ring 11 on the outside of the wood-based panel roller 10 according to the width of the wood-based panel. When adjusting, just loosen the internal hexagonal screw on the limit ring 11. At this time, one end of the internal hexagonal screw will be separated from the outer wall of the wood-based panel roller 10. Then the limit ring 11 can be pushed forward and backward for adjustment. After the adjustment is completed, tighten the internal hexagonal screw on the limit ring 11 again. At this time, one end of the internal hexagonal screw will be in close contact with the outer wall of the wood-based panel roller 10 again, so as to limit the sliding of the limit ring 11 on the outside of the wood-based panel roller 10.
[0027] Working principle of this embodiment: During installation, the device can be supported and fixed in the workshop through the main support base 1. The drive shafts on the wood-based panel conveyor belt 2 and the abrasive belt 9 are both connected to an external motor for transmission. Then, the top end of the dust suction pipe 8 is connected to the dust suction device in the workshop. When sanding the wood-based panel, first adjust the front-to-back distance between the outer limit rings 11 of the wood-based panel pressing roller 10 according to the width of the wood-based panel. When adjusting, just loosen the hexagon socket head cap screws on the limit ring 11. At this time, one end of the hexagon socket head cap screw will disengage from the outer wall of the wood-based panel pressing roller 10. Then, one of the limit rings 11 can be pushed forward and backward for adjustment. During the adjustment process, the rack 12 on one side of this limit ring 11 will drive the gear 13 to rotate. When the gear 13 rotates, it can drive the other limit ring 11 to move synchronously and in the opposite direction through the rack 12 on its side. Therefore, the distance between the two limit rings 11 can be adjusted to be equal to the width of the wood-based panel. Then, tighten the hexagon socket head cap screws on the limit ring 11 again. At this time, one end of the hexagon socket head cap screw will closely adhere to the outer wall of the wood-based panel pressing roller 10 again, so as to limit the sliding of the limit ring 11 outside the wood-based panel pressing roller 10. At this time, turn on all the motors driving the wood-based panel conveyor belt 2 and the abrasive belt 9, and place the wood-based panel to be sanded on the top of the wood-based panel conveyor belt 2 and push it backward. When the wood-based panel conveyor belt 2 drives the wood-based panel to move to the right, the right part of the wood-based panel will first be inserted into the opening between the two outer limit rings 11 of the wood-based panel pressing roller 10. At this time, the limit ring 11 can limit the front-to-back movement of the wood-based panel and prevent the limit ring 11 from shifting during the processing. Then, as the wood-based panel continues to move to the right, its right end will contact the inclined surface on the left side of the bottom of the first stop bar 4. At this time, the wood-based panel can push the first stop bar 4 it can contact upward. Finally, the bottom surface of the upward-sliding first stop bar 4 will closely adhere to the top surface of the wood-based panel. Subsequently, the top surface of the wood-based panel will contact the bottom surface of the abrasive belt 9 for sanding treatment. The debris and dust generated during the sanding process will be extracted outward by the dust suction device in the workshop through the dust suction pipe 8. During the processing, the wood-based panel will continue to move to the right. Then, the right end of the wood-based panel will contact the inclined surface on the left side of the bottom of the second stop bar 5. At this time, the wood-based panel can push the second stop bar 5 it can contact upward. Finally, the bottom surface of the upward-sliding second stop bar 5 will also closely adhere to the top surface of the wood-based panel. Therefore, during the sanding process, the openings on the left and right sides of the sanding cover 3 communicating with the outside will be relatively small, reducing the outward dispersion of dust. Finally, after the sanding treatment is completed, the wood-based panel will be conveyed out from the right side of the top of the wood-based panel conveyor belt 2. After the wood-based panel separates from the bottoms of the first stop bar 4 and the second stop bar 5, the first stop bar 4 and the second stop bar 5 can automatically slide down by gravity. At the same time, the elastic band 6 can also push the first stop bar 4 and the second stop bar 5 downward to achieve automatic return. When the abrasive belt 9 needs to be replaced, the maintenance top cover 7 can be disassembled, and then the operation can be carried out through the opening on the top of the sanding cover 3.
