[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This embodiment provides a technical solution: a wood flooring processing, sanding, and polishing machine, including a sanding and polishing housing 1. The sanding and polishing housing 1 adopts a commonly used sanding and polishing machine in the prior art, and has a drive motor inside. Support plates 3 are provided at both the front and rear ends of the interior of the sanding and polishing housing 1 to support the conveying components. A wood flooring conveyor belt 2 is provided between the two support plates 3 to convey the wood flooring. Sanding and polishing rollers 4 are respectively provided at the upper end of the interior of the sanding and polishing housing 1, and the sanding and polishing rollers 4 are respectively fixedly connected to the output shaft of the drive motor of the sanding and polishing housing 1. Next, the polishing roller 4 rotates clockwise. The rotation speed of the polishing roller 4 is greater than the conveying speed of the wood flooring, causing relative friction between the polishing roller 4 and the wood flooring. The rotation of the polishing roller 4 polishes the surface of the wood flooring. A microcontroller 6 is provided on the right side of the polishing housing 1. The input end of the microcontroller 6 is electrically connected to an external power source to control the start and stop of the entire device. The wood flooring conveyor belt 2 is an electric conveyor belt. The input end of the wood flooring conveyor belt 2 is electrically connected to the output end of the microcontroller 6. It also includes a sawdust collection mechanism 5.

[0021] Wood dust collection mechanism 5: It includes a dust collection hood 52, a suction pipe 53, and a brush roller 54. The dust collection hood 52 is respectively disposed between the upper surfaces of the two support plates 3. The polishing rollers 4 are respectively rotatably connected between the front and rear inner walls of the dust collection hood 52 via a rotating shaft one. The left end of the interior of the dust collection hood 52 is provided with a suction pipe 53. The left end between the front and rear inner walls of the dust collection hood 52 is rotatably connected to the brush roller 54 via a rotating shaft two. The brush roller 54 rotates relative to the polishing roller 4 in the same dust collection hood 52. During the polishing process, the brush roller 54 rotates relative to the polishing roller 4. By using the counterclockwise rotation of the brush roller 54, the wood dust on the surface of the wood floor is brushed, reducing the adsorption of wood dust on the surface of the wood floor, pushing the wood dust to the right, and preventing the wood dust from leaving the dust collection hood. Inside the dust collection hood 52, the wood dust generated from sanding and polishing is concentrated inside the dust collection hood 52. The dust is then collected using a suction pipe 53, which includes a pipe 531, a first suction hole 532, a second suction hole 533, and a third suction hole 534. The pipe 531 is located inside the left end of the dust collection hood 52. A first suction hole 532 is provided in the arc-shaped groove at the upper right side of the pipe 531, and is installed in conjunction with the sanding and polishing roller 4. A second suction hole 533 is provided in the arc-shaped groove at the lower left side of the pipe 531, and is installed in conjunction with the brush roller 54. A third suction hole 534 is provided on the inclined surface at the lower right end of the pipe 531. The wood dust on the surface of the wooden floor is drawn into the pipe 53 through the third suction hole 534 using the air pressure difference. Inside the polishing housing 1, the wood dust raised by the clockwise rotation of the polishing roller 4 is sucked into the pipe 531 through the first suction hole 532, and the wood dust raised by the counterclockwise rotation of the brush roller 54 is sucked into the pipe 531 through the second suction hole 533, accurately collecting the wood dust. The wood dust collection mechanism 5 also includes a wood dust collection box 51, a fan 57, and a filter screen 58. The wood dust collection box 51 is located inside the polishing housing 1. The fan 57 is located on the left side of the wood dust collection box 51. The air inlet of the fan 57 is connected to the air outlet of the wood dust collection box 51. The air inlet of the wood dust collection box 51 is connected to the air outlet of the pipe 531 through a connecting hose. The filter screen 58 is located at the left end of the interior of the wood dust collection box 51. The input end of the fan 57 is electrically connected to the microcontroller 6. At the output end, the fan 57 is started, drawing air out of the sawdust collection box 51 to create negative pressure inside. This pressure difference is used to collect the wood dust. A filter 58 filters the wood dust from the airflow, keeping it inside the sawdust collection box 51. The sawdust collection mechanism 5 also includes a blower pipe 55 and an air pump 56. The blower pipe 55 is located inside the dust collection hood 52 at the right end, and the air pump 56 is located on the right side of the sawdust collection box 51. The air inlet of the blower pipe 55 is connected to the air outlet of the air pump 56 via a connecting hose. The input end of the air pump 56 is electrically connected to the output end of the microcontroller 6. Starting the air pump 56 provides power for the airflow, causing the airflow to exit from the arc-shaped tube at the lower end of the blower pipe 55.To prevent wood dust generated during sanding and polishing from moving to the right and leaving the right end of the dust collection hood 52, the suction pipe 53 also includes scrapers 535, which are respectively disposed between the front and rear inner walls of suction holes one 532 and two 533. During rotation, the bristles of the sanding and polishing roller 4 and the brush roller 54 collide with adjacent scrapers 535, causing wood dust on the surfaces of the sanding and polishing roller 4 and the brush roller 54 to fall off and be sucked into the pipe 531 through suction holes one 532 and two 533 respectively. Gears 7 are provided at the front end of the second rotating shaft of the brush roller 54 and the front end of the first rotating shaft of the sanding and polishing roller 4. The front surface of the dust collection hood 52 is rotatably connected to transmission gears 8 via a rotating shaft three. Gears 7 and transmission gears 8 on the same surface of the dust collection hood 52 mesh sequentially from left to right. Through the transmission connection of gears 7 and transmission gears 8, the sanding and polishing roller 4 and the brush roller 54 rotate relative to each other.

[0022] The working principle of the wood flooring processing, sanding, and polishing machine provided by this utility model is as follows: During the wood flooring processing, the wood flooring is placed on the upper surface of the wood flooring conveyor belt 2. The single-chip microcomputer 6 starts the wood flooring conveyor belt 2, which transports the wood flooring to the left. Then, the single-chip microcomputer 6 starts the drive motor inside the sanding and polishing housing 1, which drives the sanding and polishing roller 4 to rotate clockwise. The rotation speed of the sanding and polishing roller 4 is greater than the conveying speed of the wood flooring, so that relative friction is generated between the wood flooring and the sanding and polishing roller 4, thereby achieving sanding and polishing of the wood flooring. During the sanding and polishing process, the blower 57 is started, which extracts the air from the sawdust collection box 51, creating a negative pressure inside the sawdust collection box 51. The pressure difference is used to draw the wood dust on the surface of the wood flooring into the pipe 531 through the dust suction hole 3 534. At the same time, the air pump 56 is started to provide power for the air flow, so that the airflow exits from the arc-shaped pipe at the lower end of the blower pipe 55. The airflow prevents the wood dust generated during sanding and polishing from moving to the right. Simultaneously, the transmission connection between gear 7 and drive gear 8 causes the sanding and polishing roller 4 and the brush roller 54 to rotate relative to each other. The counter-clockwise rotation of the brush roller 54 brushes away the wood dust on the surface of the wood floor, reducing its adhesion and pushing it to the right, preventing it from leaving the dust collection hood 52. Meanwhile, the wood dust raised by the clockwise rotation of the sanding and polishing roller 4 is sucked into the pipe 53 through the suction hole 532. Inside, the wood dust raised by the counterclockwise rotation of the brush roller 54 is sucked into the pipe 531 through the second suction hole 533. During the rotation, the bristles of the polishing roller 4 and the brush roller 54 collide with the adjacent scraper 535, causing the wood dust on the surface of the polishing roller 4 and the brush roller 54 to fall off and be sucked into the pipe 531 through the first suction hole 532 and the second suction hole 533 respectively. This makes the collection of wood dust more comprehensive, reduces the residue of wood dust on the surface of the wooden floor, and facilitates subsequent processing.

[0023] It is worth noting that the microcontroller 6 disclosed in the above embodiments can be an AT89C4051 microcontroller. The wooden floor conveyor belt 2, the fan 57, and the air pump 56 can be freely configured according to the actual application scenario. The wooden floor conveyor belt 2 can be an RF-PDSSJ electric conveyor belt, the fan 57 can be a C4-73 dust removal centrifugal induced draft fan, and the air pump 56 can be a D35S-22X air pump. The microcontroller 6 controls the operation of the wooden floor conveyor belt 2, the fan 57, and the air pump 56 using methods commonly used in the prior art.
