[0002] Paint-free boards are decorative boards made by hot-pressing paper with different colors or textures laid on particleboard, moisture-proof board, medium-density fiberboard, paint-free board, blockboard or other solid wood board. Paint-free boards do not require surface treatment with paint, so they will not release harmful gases and are harmless to the environment and human health. Paint-free boards do not require paint treatment, and the construction process is simple and quick, which can greatly shorten the construction period.

[0003] Paint-free boards will generate dust during the production and processing process, and need to be effectively cleaned. Usually, water spray cleaning is used. By spraying water on the paint-free boards, the dust attached to the surface is washed away to restore the surface cleanliness.

[0026] Embodiment 1, this embodiment proposes a dust removal device for paint-free board production, such as Figure 1 As shown, it includes a dust removal bin 1, on the left and right sides of the dust removal bin 1 are fixedly installed assembly line frames 2, on the left and right sides of the dust removal bin 1 are opened feeding ports 3 at the same height as the assembly line frames 2, the interior of the dust removal bin 1 is rotatably connected to a lower guide roller 8, a tool plate 4 is provided inside the dust removal bin 1, the inner side of the tool plate 4 is rotatably connected to an upper guide roller 9, the paint-free board is transported between the lower guide roller 8 and the upper guide roller 9, the assembly line frame 2 transports the paint-free board into the dust removal bin 1, and the lower guide roller 8 and the upper guide roller 9 transport the paint-free board into the dust removal bin 1.

[0027] like Figure 2 and Figure 3 As shown, the inner wall of the dust removal bin 1 is provided with a water spray assembly 5, which includes a lateral roller 51, a deflection rod 52, an embedded shaft 53, an amplifying assembly, a tooth plate 57, a closing plate 59 and a water spray port 510. The upper and lower ends of the lateral roller 51 are rotatably connected to the deflection rod 52 through a rotating shaft. The end of the deflection rod 52 is fixedly installed with the embedded shaft 53. Two deflection rods 52 are provided and symmetrically distributed on the inner wall of the dust removal bin 1, as shown in FIG. Figure 4 As shown, the two deflection rods 52 are respectively located on both sides of the paint-free plate, and the embedded shaft 53 is rotatably installed on the inner wall of the dust removal bin 1. After the paint-free plate enters the dust removal bin 1, the paint-free plate pushes the lateral roller 51 and the deflection rod 52, and the lateral roller 51 and the deflection rod 52 are deflected to drive the amplification component to move.

[0028] like Figure 3 and Figure 4As shown, an amplifying assembly is arranged at the top of the embedded shaft 53, and the amplifying assembly amplifies the moving distance of the tooth plate 57, so that the deflection displacement of the lateral roller 51 and the deflection rod 52 is close to the displacement of the tooth plate 57. The amplifying assembly includes a first gear 54, a second gear 55 and a third gear 56. The bottom center of the third gear 56 is fixedly connected to the embedded shaft 53, the first gear 54 is meshed with the second gear 55, the top center of the first gear 54 is coaxially connected to the third gear 56, the third gear 56 is meshed with the tooth plate 57, the connecting shaft between the first gear 54 and the third gear 56 is rotatably connected to the tool plate 4, the diameter of the third gear 56 is larger than the diameter of the first gear 54, and the diameter of the first gear 54 is larger than the diameter of the second gear 55. The rotation angle of the third gear 56 is increased by the gear ratio to increase the displacement distance of the tooth plate 57.

[0029] like Figure 5 As shown, the enlarged component is engaged with the tooth plate 57, a plurality of water outlets 510 are provided at the bottom of the tool plate 4, the deflection rod 52 and the plurality of water outlets 510 are in the same vertical plane, a closing plate 59 is fixedly installed at the bottom of the tooth plate 57, a slide groove 58 is provided in the middle of the tool plate 4, the connecting part between the tooth plate 57 and the closing plate 59 slides at the slide groove 58, the slide groove 58 guides the tooth plate 57 and the closing plate 59, and the closing plate 59 slides at the water outlet 510 at the bottom of the tool plate 4.

[0030] After the lateral roller 51 and the deflection rod 52 are deflected, the tooth plate 57 is driven to move through the amplification component, and the tooth plate 57 slides along the slide groove 58. The tooth plate 57 releases a corresponding number of water spray outlets 510 according to the deflection angles of the lateral roller 51 and the deflection rod 52, so that the number of water spray outlets 510 for spraying water is adapted to the front and rear dimensions of the paint-free board, thereby avoiding the situation where there is no paint-free board under some of the water spray outlets 510 among the multiple water spray outlets 510, and the water sprayed from the water spray outlet 510 at this position has no contact with the paint-free board.

[0031] At the same time, the lateral roller 51 and the deflection rod 52 cooperate to ensure that the water spray port 510 directly above the paint-free board is always in an open state. Since the paint-free board is tilted after entering the dust removal bin 1, when the paint-free board moves to the water spray port 510, the closing plate 59 adjusts the position of the water spray port 510 while keeping the number of the water spray port 510 unchanged according to the position of the paint-free board, so that the water spray port 510 directly above the tilted paint-free board is always spraying water.

[0032] like Figure 5As shown, the paint-free plate is flushed through the water spray outlets 510, the tool plate 4 adopts an inverted U-shaped structure, and multiple water spray outlets 510 are evenly distributed along a straight line at the bottom horizontal plane of the tool plate 4. The closing plate 59 moves along the straight line formed by the multiple water spray outlets 510. There is a spacing between the water spray outlets 510 located at the edge and the vertical surfaces on both sides of the tool plate 4. The spacing is used for the displacement of the closing plate 59 to prevent the closing plate 59 from being restricted by the tool plate 4 and unable to move when the closing plate 59 slides to leak the water spray outlets 510.

[0033] In the present embodiment, after the paint-free plate enters the dust removal bin 1, the paint-free plate deflects the lateral roller 51 and the deflection rod 52 so that the tooth plate 57 slides. The tooth plate 57 releases a corresponding number of water spray outlets 510 according to the deflection angles of the lateral roller 51 and the deflection rod 52, so that the number of water spray outlets 510 for spraying water is adapted to the front and rear dimensions of the paint-free plate, thereby avoiding the situation where there is no paint-free plate below some of the water spray outlets 510 among the multiple water spray outlets 510, and the water sprayed from the water spray outlet 510 at this position has no contact with the paint-free plate, resulting in water waste.

[0034] Example 2, based on Example 1, this example proposes a dust removal device for paint-free board production, such as Figure 6 As shown, a distance control assembly 6 is provided on the top of the tool plate 4, and the distance control assembly 6 includes a support frame, a deflection plate 64, a vertical roller 65, a slider 66, a top rod 67, a connecting frame, a bending rod 610 and a flat brush 611. The support frame includes a fixed column 61, a horizontal plate 62 and a fixed block 63. The top of the fixed column 61 is fixedly connected to the dust removal bin 1, the bottom of the fixed column 61 is fixedly installed with the horizontal plate 62, the bottom of the middle position of the horizontal plate 62 is fixedly installed with the fixed block 63, the bottom of the fixed block 63 is rotatably connected to the deflection plate 64, and the side of the deflection plate 64 is rotatably connected to the vertical roller 65.

[0035] When the paint-free board moves to the vertical roller 65, the paint-free board squeezes the vertical roller 65 and the deflection plate 64 to deflect them. The deflection angle of the vertical roller 65 is different if the thickness of the paint-free board is different. The thickness of the paint-free board is tested by the vertical roller 65 and the fixed block 63.

[0036] like Figure 6 and Figure 7 As shown, a telescopic rod 612 is fixedly installed between the bottom of the horizontal plate 62 and the tool plate 4, and the telescopic rod 612 guides the tool plate 4. The side of the deflection plate 64 is slidably connected to the slider 66, and the top of the slider 66 is hinged to the top rod 67. A connecting frame is fixedly installed on the rod body of the top rod 67. The connecting frame includes a longitudinal rod 68 and a transverse rod 69. The two ends of the longitudinal rod 68 are respectively fixedly connected to the top rod 67 and the transverse rod 69.

[0037] When the deflection plate 64 deflects, the deflection plate 64 uses the slider 66 to push the push rod 67 upward, and the slider 66 prevents the push rod 67 from getting stuck. The push rod 67 uses the longitudinal rod 68 and the transverse rod 69 to drive the tool plate 4 to move, thereby adjusting the height of the upper guide roller 9 so that the upper guide roller 9 can transport the paint-free board.

[0038] like Figure 8 As shown, the transverse rod 69 adopts an inverted U-shaped structure, both ends of the transverse rod 69 are fixedly connected to the tool plate 4, the rod body of the top rod 67 is slidably connected to the horizontal plate 62, and the top of the top rod 67 is fixedly installed with a limit plate 613. The side of the tool plate 4 is fixedly installed with a bending rod 610, and the bottom of the bending rod 610 is fixedly installed with a flat brush 611. The flat brush 611 and the vertical roller 65 are both in contact with the top of the paint-free plate, and the water spray port 510 is inclined, and the water spray port 510 is facing the paint-free plate contacted by the flat brush 611. The water spray port 510 is inclined to reduce water splashing.

[0039] The tool plate 4 moves upward to change the height of the water spray port 510 and the flat brush 611, so that the flat brush 611 is always in contact with the paint-free board, thereby adapting to paint-free boards of different sizes. The height of the water spray port 510 is adapted to the paint-free board, maintaining the pressure of the water sprayed from the water spray port 510, maintaining the impact force of the water on the paint-free board, and stabilizing the cleaning effect of the paint-free board.

[0040] In this embodiment, when the paint-free board moves to the vertical roller 65, the paint-free board squeezes the vertical roller 65 and the deflection plate 64 to deflect it. The deflection plate 64 uses the slider 66 to push the push rod 67 upward to adjust the height of the tool plate 4, so that the flat brush 611 is always in contact with the paint-free board, thereby adapting to paint-free boards of different sizes.

[0041] Embodiment 3, based on the above-mentioned embodiment 1 or embodiment 2, this embodiment proposes a dust removal device for paint-free board production, such as Fig. 9 As shown, a recovery component 7 is provided on the inner wall of the dust removal bin 1 and below the upper guide roller 9. The recovery component 7 includes a filter 71, a connecting plate 72, a discharge port 73, a partition 74 and a recovery pipe 76. The filter 71 is fixedly mounted on the inner wall of the dust removal bin 1. The filter 71 is tilted. A connecting plate 72 is fixedly mounted on the right side of the filter 71. A discharge port 73 is provided at the center of the connecting plate 72. Water sprayed from the water spray port 510 flows toward the filter 71.

[0042] The water spray port 510 flushes the paint-free board to wash away the impurities on the paint-free board, and the water containing impurities falls on the filter screen 71. The filter screen 71 separates the impurities and water to recycle the water for reuse, while the impurities are intercepted by the filter screen 71. While the water containing impurities is filtered through the filter screen 71, the water flushes the impurities on the top of the filter screen 71, and the water flushes the impurities toward the connecting plate 72 along the filter screen 71. In the process of flowing toward the connecting plate 72, the water falls under the filter screen 71, and the impurities are gradually flushed toward the connecting plate 72 and fall from the connecting plate 72 through the discharge port 73, so as to prevent the impurities from being on the top of the filter screen 71 for a long time and clogging the filter screen 71.

[0043] like Figure 2 As shown, a partition 74 is fixedly installed at the bottom of the connection between the filter 71 and the connecting plate 72, and the partition 74 divides the dust removal bin 1 into a recovery bin 75 and an impurity bin 77. A bin door 78 is rotatably connected to the side of the dust removal bin 1 and located at the impurity bin 77. A recovery pipe 76 is provided on the inner wall of the dust removal bin 1 and located below the filter 71. Water is at the top of the filter 71 and close to the connecting plate 72, and completely falls to the bottom of the filter 71.

[0044] After the filter screen 71 filters the impurities, the water falls into the recovery bin 75 and is recovered through the recovery pipe 76, while the impurities accumulate at the connection between the filter screen 71 and the connecting plate 72, and slide into the impurity bin 77 under the action of the inclined filter screen 71. The impurities and water inside the impurity bin 77 are cleaned by opening the bin door 78.

[0045] In this embodiment, water and impurities are filtered by an inclined filter screen 71 to recover water. After being filtered by the filter screen 71, the impurities remain on the top of the filter screen 71. After the paint-free board is flushed by the water spray port 510, the water containing impurities impacts the impurities on the top of the filter screen 71. The water and impurities move along the top of the filter screen 71 toward the connecting plate 72. During the movement of water and impurities, the water is filtered by the filter screen 71, and the impurities move to between the filter screen 71 and the connecting plate 72 and accumulate during the continuous flushing process. Under the action of the inclined filter screen 71, they fall to the connecting plate 72 to prevent the impurities from covering the top of the filter screen 71 and affecting the filtering effect of the filter screen 71.

[0046] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
