[0023] like Figures 1-4 As shown, a debris collection device for furniture processing includes a processing platform 1, on which a cutting saw 2 is mounted. A splash guard 3 is mounted above the cutting saw 2. Specifically, the opening of the splash guard 3 is located downstream of the sawdust splash path. The side of the splash guard 3 is fan-shaped with a large opening angle (usually 120° to 180°), which can cover the arc or fan-shaped working range of the cutting tool or processing area, ensuring that sawdust enters the adsorption area immediately after it is generated, reducing the possibility of splashing to the outside. In addition, the fan-shaped design conforms to the airflow characteristics and can guide the airflow to be evenly distributed to the cutting area, forming a stable negative pressure field. Compared with a flat or narrow opening structure, the gradually expanding opening of the fan-shaped splash guard 3 can reduce airflow resistance, allowing high-speed sawdust (including dust) to be more smoothly sucked into the pipe under the action of inertia and negative pressure, avoiding sawdust rebound or escape caused by airflow turbulence. The cutting saw 2 is equipped with a U-shaped auxiliary baffle located downstream of the sawdust splash path to guide the splash direction and prevent sawdust from being not adsorbed due to excessive speed during the cutting process.

[0024] The splash guard 3 has a dust suction port 7 on its side wall away from the cutting saw 2. The dust suction port 7 is connected to a cyclone separator 9 via a telescopic hose 8. The discharge port of the cyclone separator 9 is connected to a debris collection box 10 to collect the separated debris for centralized processing. The working principle of the cyclone separator 9 is as follows: The cyclone separator 9 is a device that uses centrifugal force to achieve gas-solid separation. The core principle is that the high-speed rotation of the airflow causes the particles to generate inertial centrifugal force, thereby separating them from the gas. The specific process is as follows:

[0025] 1) Dust-laden airflow enters: Gas containing wood chips and dust enters the cylindrical body at high speed from the tangential air inlet of the separator, forming a spiraling downward rotating airflow (called "external vortex").

[0026] 2) Centrifugal separation of particles: Solid particles (such as sawdust and dust) are much denser than gases. Under the action of centrifugal force, they are thrown towards the inner wall of the cylinder. After colliding with the wall, they lose kinetic energy and slide down the wall to the bottom cone collection area.

[0027] 3) Clean gas discharge: The separated gas forms a spiral upward internal vortex in the center and is finally discharged from the exhaust pipe at the top, entering subsequent treatment (such as filter cartridge filtration) or being directly discharged.

[0028] The air outlet of the cyclone separator 9 is connected to the filter 12 through the air duct 11. The filter element inside the filter 12 is made of polyester fiber filter cartridge, which is used to intercept fine dust (≤10μm) to prevent dust from being emitted into the workshop air. It needs to be cleaned or replaced regularly.

[0029] The filter 12 is connected to the centrifugal fan 14 through the second air duct 13, which provides negative pressure power, so that the internal air pressure of the system is lower than the ambient air pressure, and the external air carrying waste is sucked into the duct.

[0030] A cantilever 4 is installed on the outer wall of the splash shield 3. The end of the cantilever 4 away from the splash shield 3 is connected to a lifting mechanism 5, which adjusts the height of the splash shield 3. A moving mechanism 6 is installed at the bottom of the lifting mechanism 5, which adjusts the position of the splash shield 3 in the front-back direction.

[0031] The lifting mechanism 5 includes a lead screw 501 located at the bottom of the cantilever 4. The lead screw 501 is threadedly connected to a lead screw sleeve 502. A worm gear mechanism 505 is installed around the outer periphery of the lead screw sleeve 502. A housing is installed around the outer periphery of the worm gear mechanism 505. A support cylinder 507 is installed below the worm gear mechanism 505, and a mounting base 508 is installed at the bottom of the support cylinder 507. A limit groove 503 is formed on the lead screw 501, and a limit block 504 that cooperates with the limit groove 503 is installed on the housing. The diameter of the support cylinder 507 is larger than the diameter of the lead screw 501 to provide space for the lead screw 501 to move up and down. The worm gear mechanism 505 includes a worm wheel sleeved around the outer periphery of the lead screw sleeve 502. The worm wheel meshes with a worm, and the worm's shaft 506 passes through the housing and is connected to a forward and reverse motor.

[0032] The lifting process is as follows: the forward and reverse motor starts, the worm gear mechanism 505 drives the screw nut 502 to rotate, and under the restriction of the limit groove 503 and the limit block 504, the screw 501 moves up and down according to the screw principle.

[0033] There are multiple implementations of the moving mechanism 6. The following implementation is adopted in this embodiment:

[0034] The moving mechanism 6 includes a linear guide rail 601, on which a linear slider 602 is slidably mounted. The linear slider 602 is driven to reciprocate by a linear motor 603. The linear motor 603 is a device that directly converts electrical energy into linear motion mechanical energy. It mainly consists of a stator and a mover. When an alternating current is applied to the stator winding, a traveling wave magnetic field is generated. Under the action of the magnetic field, the mover moves in a straight line, thereby driving the linear slider 602 to reciprocate on the linear guide rail 601.

[0035] The operation process of this utility model is as follows:

[0036] First, based on the sawdust splash path, the height of the splash shield 3 is adjusted by the lifting mechanism 5, and the front and rear positions of the splash shield 3 are adjusted by the moving mechanism 6. Then, the centrifugal fan 14 is started to make the air pressure inside the pipe lower than the ambient air pressure, and the outside air carrying the sawdust is sucked into the pipe. Finally, the sawdust (including dust) enters the cyclone separator 9 from the dust suction port 7 on the splash shield 3 for solid-gas separation. The sawdust falls into the sawdust collection box 10 below, and the gas enters the filter 12 from the upper air outlet for dust filtration. The purified air is discharged by the centrifugal fan 14.

Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
