[0023] In one embodiment, such as Figures 1 to 4As shown, an automated dust removal, heating, and veneer application device 10 for furniture boards includes: a conveyor bed 100 and a dust removal mechanism 200, a heating mechanism 300, a veneer application mechanism 400, and a cooling mechanism 500 sequentially arranged on the conveyor bed 100; a dust cover 110 is provided at the middle of the upper end of the conveyor bed 100, and the dust cover 110 has an inlet and an outlet at both ends along the length of the conveyor bed 100; the heating mechanism 300 and the veneer application mechanism 400 are disposed inside the dust cover 110, and the dust removal mechanism 200 and the cooling mechanism 500 are respectively disposed at both ends of the dust cover 110; the dust removal mechanism 200... The mechanism 200 includes a dust removal bracket mounted on the conveyor bed 100, a roller brush 210 rotatably connected to the dust removal bracket, a negative pressure suction port 220 fixed on the dust removal bracket, and an airflow nozzle 230 mounted on the feed inlet; the roller brush 210 is perpendicular to the feeding direction of the plate and is connected to a first motor mounted on the side wall of the dust removal bracket; the negative pressure suction port 220 is parallel to the roller brush 210 and is connected to a negative pressure generator 221; the airflow nozzle 230 is connected to a high-pressure air pump 231; both the high-pressure air pump 231 and the negative pressure generator 221 are mounted on the outside of the conveyor bed 100.

[0024] In this embodiment, the conveyor bed 100 is a roller conveyor bed. A drive motor rotates the rollers, causing the sheet material to move forward. A dust cover 110 is provided in the middle section of the upper end face of the roller conveyor bed 100. The dust cover 110 has an inlet and an outlet at both ends for the sheet material to pass through. A dust removal mechanism 200 for removing dust from the sheet material is provided outside the inlet. The dust removal mechanism 200 includes a dust removal bracket fixedly connected to both sides of the upper end face of the conveyor bed 100. The dust removal bracket has a roller brush 210 with bristles and a negative pressure suction port 220 for collecting dust. Both ends of the roller brush 210 are rotatably connected to the side wall of the dust removal bracket, and one end of the roller brush 210 passes through the side wall of the dust removal bracket and is fixedly connected to the output end of a first motor fixed to the outer side wall of the dust removal bracket. The first motor drives the roller brush 210 to rotate, sweeping away the dust from the surface of the sheet material fed onto the conveyor bed 100. Large particles of dust and other impurities are removed, reducing the probability of blistering after the board is veneered. The negative pressure suction port 220 is a flat, elongated structure. It is fixed on the dust removal bracket and located on the side of the roller brush 210 near the dust cover 110. The upper end of the negative pressure suction port 220 is connected to the negative pressure generator 221 installed on the outside of the conveyor bed 100 through the first air pipe. The negative pressure generator 221 generates negative pressure, causing dust to enter from the negative pressure suction port 220 and enter the dust collection box along the first air pipe, thereby reducing the density of dust in the air. The dust removal mechanism 200 also includes multiple airflow nozzles 230 arranged at equal intervals on the feed inlet. The airflow nozzles 230 are connected to the high-pressure air pump 231 installed on the outside of the conveyor bed 100 through the second air pipe. The airflow nozzles 230 are tilted towards the outside of the dust cover 110, so that the high-pressure airflow from the nozzles blows the dust away from the outside of the dust cover 110. It is worth noting that the roller conveyor bed 100 is existing technology and will not be described in detail here.

[0025] Specifically, a guide plate for changing the direction of movement of the sheet material is provided above the conveyor bed 100. There are two guide plates, which are symmetrically arranged on both sides of the upper end face of the conveyor bed 100. The front end of the guide plate is an inclined plate and the rear end is a straight plate, so that the distance between the front ends of the two guide plates gradually decreases along the direction of sheet material movement, and the distance remains unchanged at the rear end. Furthermore, the rear end of the guide plate is parallel to the side wall of the conveyor bed 100, so that the direction of the sheet material can be adjusted during movement, and one side of the sheet material is parallel to the rear end of the guide plate.

[0026] Furthermore, a partition perpendicular to the board feeding direction is provided inside the dust cover 110, dividing the interior of the dust cover 110 into two chambers. The partition is provided with through holes for the board to pass through. The heating mechanism 300 is located in the chamber near the feed port, and the skinning mechanism 400 is located in the chamber near the discharge port. This allows the board to be heated and skinned sequentially inside the dust cover 110, which can prevent large dust particles from falling onto the surface of the board during the heating and skinning process, thereby improving the skinning qualification rate.

[0027] To prevent deformation of the board due to temperature differences between the top and bottom during heating, the heating mechanism 300 includes an infrared heating tube 310 for heating the top of the board and a hot air heating component for heating the bottom surface of the board. The dust cover 110 has a fixed plate inside, and the infrared heating tubes 310 are installed at equal intervals below the fixed plate. The infrared heating tubes 310 are connected to an external power source. The upper surface of the board is heated by the infrared heating tubes 310, which facilitates the softening and adhesion of the adhesive layer on the veneer paper to the upper surface of the board during the next step of veneer application.

[0028] Furthermore, the hot air heating component includes a wind box 330 fixed to the bottom of the conveyor bed 100. The wind box 330 has an upper opening, allowing hot air to heat the lower surface of the board through the gaps between the rollers on the conveyor belt. A perforated flow equalization plate 331 is provided in the middle of the wind box 330. The lower end of the wind box 330 is connected to one end of a connecting pipe, and the other end of the connecting pipe is connected to a hot air blower 320 located outside the conveyor bed 100. The hot air blower 320 continuously generates hot air and delivers it into the wind box 330 through the connecting pipe. After passing through the perforated flow equalization plate 331, the hot air evenly covers the bottom surface of the board, avoiding deformation of the board due to unilateral heating.

[0029] Specifically, the skin-applying mechanism 400 includes a skin-applying bracket 410 fixed to the upper end face of the conveyor bed 100. The bottom of the skin-applying bracket 410 is rotatably connected to the lower pressure roller 430, and the upper end of the lower pressure roller 430 is at the same height as the upper end of the conveyor bed 100, allowing the sheet material to pass smoothly over the lower pressure roller 430. Vertically arranged adjusting slide rails 420 are provided on the opposite side walls of the skin-applying bracket 410. Fixed blocks are mounted on the adjusting slide rails 420, and both ends of the upper pressure roller 440 are rotatably connected to the fixed blocks, allowing the height of the upper pressure roller 440 on the adjusting slide rails 420 to be adjusted. The upper pressure roller 440, the lower pressure roller 430, and the adjusting slide rails 420 are all in the same vertical plane. A second motor is fixed to the side wall of the conveyor bed 100. The output end of the second motor passes through the side wall of the conveyor bed 100 and is fixedly connected to one end of the lower pressure roller 430. The ends of the upper pressure roller 440 and the lower pressure roller 430 are respectively provided with driven wheels and driving wheels. The driven wheels and driving wheels are connected by a belt so that the upper pressure roller 440 and the lower pressure roller 430 rotate synchronously. The unwinding roller 450 is set above the coating bracket 410. The coating paper is wound on the unwinding roller, and one end of the coating paper extends between the upper pressure roller 440 and the lower pressure roller 430. The coating paper is provided with an adhesive layer. When the board passes between the upper pressure rollers 440, the coating paper is adhered to the surface of the board. In order to facilitate the replacement of the coating paper, a box door is opened on the side wall of the dust cover 110. When the coating paper is used up, the box door can be opened to replace the new coating paper.

[0030] To promptly remove excess adhesive paper from the board surface, a vertically downward-facing drive cylinder 460 is fixed to the inner top of the adhesive paper support 410. A sliding groove is provided on the opposite side wall of the adhesive paper support 410. A crossbar 470 is fixed to the output end of the drive cylinder 460, with both ends of the crossbar 470 slidably connected to the sliding groove, allowing the crossbar 470 to move vertically along the groove. A cutter 480 is fixed to the bottom of the crossbar 470 for cutting the adhesive paper. Both the crossbar 470 and the cutter 480 are perpendicular to the board's moving direction. To ensure timely cutting, a photoelectric sensor is provided at the lower end of the sliding groove. The transmitter and receiver of the photoelectric sensor are respectively located on opposite side walls of the adhesive paper support 410, at the same height as the board. When the end of the board passes through, the photoelectric sensor triggers a signal, and the drive cylinder 460 controls the crossbar 470 and the cutter 480 to move downwards, thereby cutting the adhesive paper.

[0031] To enable rapid forming of the bonded board and veneer paper after lamination, a cooling mechanism 500 is provided outside the discharge port of the dust cover 110. The cooling mechanism 500 includes a cooling bracket fixed on the conveyor bed 100, a cold air outlet 520 fixed on the cooling bracket, and a rubber roller 510 for further pressing the veneer paper. The rubber roller 510 is rotatably connected to the cooling bracket, and a third motor is fixedly connected to the outer wall of the cooling bracket. The third motor is fixedly connected to the end of the rubber roller 510. The rubber roller 510 can improve uniform pressure. When the board passes through the cooling mechanism, the deformation of the rubber can make the pressure evenly distributed on the contact surface between the veneer material and the board, thereby ensuring that the veneer paper is evenly stressed and that every part of the veneer paper is bonded to the board. The cold air outlet 520 is connected to a cold air blower 530 through an air pipe. The cold air outlet 520 is located outside the rubber roller 510. By blowing cold air on the upper end of the board, the temperature of the board is rapidly reduced, thereby rapidly cooling and forming the adhesive layer, which is then tightly bonded to the surface of the board, completing the veneer process.

[0032] The general workflow of this utility model is as follows: The conveyor bed 100 is started, and the sheet material is placed on it. The sheet material moves along the conveyor bed 100. When passing the guide plate, the angle of the sheet material can be adjusted to make it parallel to the direction of movement. When passing the dust removal mechanism 200, it first passes through the roller brush 210 to remove dust adhering to the sheet material, and then the dust is collected through the negative pressure dust suction port 220 to reduce air pollution. When passing through the feed inlet, the airflow nozzle 230 sprays high-pressure airflow to blow out the dust, while also preventing large particles of dust in the air from entering the dust cover 110. The sheet material is heated inside the dust cover 110 first, using infrared heating... Heat pipe 310 heats the upper surface of the board, and hot air heating component heats the bottom of the board to prevent deformation caused by heating one side. Then it enters the bonding mechanism 400, where the upper and lower pressure rollers 430 rotate synchronously to press the bonding paper onto the upper surface of the board. When the end of the board passes the photoelectric sensor, the drive cylinder controls the cutter 480 to move down and cut the bonding paper. Then, the rubber pressure roller 510 further presses the board so that all parts of the bonding paper are adhered to the board. Finally, cold air is blown onto the top of the board through the cold air outlet 520 to cool and shape the bonded board, cure the adhesive layer, and reduce the temperature of the board to a suitable range for subsequent processing.
