DETAILED DESCRIPTION

[0016] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] Embodiment 1:

[0018] like Figure 1 As shown, a wood board polishing device comprises a conveying assembly 1 and a polishing assembly 2, wherein the conveying assembly 1 comprises two sets of horizontally arranged conveying belt mechanisms 110 and a driving mechanism 120 which is transmission-connected with the two sets of the conveying belt mechanisms 110, wherein the two sets of the conveying belt mechanisms 110 are arranged in parallel and at the same height, wherein the conveying belt mechanism 110 comprises a conveying belt 111 having a thickness and a transmission wheel 112, wherein the transmission wheel 112 is a gear, wherein a tooth groove is arranged on the inner side of the conveying belt 111, and wherein the rotating shaft of the transmission wheel 112 is rotationally connected with a supporting structure fixed on the ground, and the two transmission wheels 112 on the same side of the two sets of conveying belt mechanisms 110 are transmission-connected with the driving mechanism 120 and driven thereby to run synchronously and at the same speed;

[0019] In order to facilitate pushing the wooden board through the polishing assembly 2, the conveyor belt 111 is provided with a plurality of mounting grooves 113 evenly distributed along its length direction, and a push plate 114 is movably provided in the mounting groove 113, and the push plate 114 and the mounting groove 113 are clearance-matched and the clearance is zero, and one end of the push plate 114 is rotatably connected to the inner side wall of the mounting groove 113, and the thickness of the push plate 114 is not greater than the depth of the mounting groove 113 so that it does not protrude from the surface of the conveyor belt 111, so that when the wooden board is placed on the surface of the conveyor belt 111, it will not be affected by the push plate 114 at its bottom;

[0020] During the conveying process of the wooden board, the push plate 114 is erected and the side of the wooden board is in contact with the push plate 114. When the push plate 114 pushes the wooden board through the polishing assembly 2, the wooden board is subjected to the reaction of the polishing assembly 2 and will not move relative to the conveying assembly 1, so that the wooden board can pass through the polishing assembly 2 at a uniform speed, thereby ensuring the polishing quality.

[0021] Specifically, in order to improve the stability of the push plate 114 when pushing the wooden board, in a further embodiment, as Figure 2 As shown, a rotating shaft 115 is fixedly connected to the side surface of one end of the push plate 114, a rotating hole 116 is provided on the inner side wall of the mounting groove 113, and a limiting rod 117 which is parallel to and close to the rotating shaft 115 is also fixedly connected to the side surface of the push plate 114, and an arc-shaped limiting groove 118 is provided on the inner side wall of the mounting groove 113;

[0022] The limiting groove 118 has the same rotation path as the limiting rod 117, and the limiting groove 118 has only a quarter arc length. When the push plate 114 is rotated, the push plate 114 can only rotate 90° under the action of the limiting rod 117 and the limiting groove 118, and switch between the horizontal and vertical states.

[0023] In order to ensure that the push plate 114 does not rotate when located in the installation groove 113 , in a further embodiment, the push plate 114 is a magnetic plate, and a magnet block 119 for adsorbing the push plate 114 is provided at the bottom of the installation groove 113 .

[0026] The lifting mechanism 220 can drive the two sets of polishing mechanisms 210 to move closer to or farther from each other, so as to adapt to the double-sided polishing of wood boards with different thicknesses;

[0027] In order to clean the dust generated by polishing the wood board in time, Figure 3 As shown, in a further embodiment, the polishing mechanism 210 includes a lifting seat 211, a polishing roller 212 and a cleaning roller 213 rotatably connected to the lifting seat 211, and a driving component 214 disposed in the lifting seat 211, and the driving component 214 is transmission-connected to the polishing roller 212 and the cleaning roller 213;

[0028] Specifically, the cleaning roller 213 is provided with a plurality of cleaning brushes 215 evenly distributed along its circumference;

[0029] In order to prevent the dust generated by polishing from spreading, in a further embodiment, the cleaning roller 213 is provided with an internal cavity 216 arranged along its axial direction, and the cleaning roller 213 is provided with a dust exhaust hole 217 located between the two cleaning brushes 215 and connected to the cavity 216.

The cavity 216 passes through one end of the rotating shaft of the cleaning roller 213 along its axial direction, and the rotating shaft of the cleaning roller 213 on this side passes through the side wall of the lifting seat 211 and is rotatably connected thereto through a rotating bearing, and the end of the rotating shaft on this side is connected to the inlet pipe of the vacuum cleaner 218 through a rotating joint to connect the vacuum cleaner 218 with the internal cavity 216. Negative pressure is generated by the vacuum cleaner 218, and after the cleaning brush 215 brushes up the dust on the wooden board, the dust can be sucked into the cavity 216 and discharged through the pipe connected to the cavity 216.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
