Detailed implementation manners

[0029] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0030] Please refer to Figures 1 to 9, the present invention provides a formaldehyde detection device for building materials, comprising a box body 1, a bracket 2, a conveyor 3, a clamping unit, an air inlet unit, a formaldehyde detector 4 and a cleaning assembly. The cleaning assembly includes a ventilation pipe 6, a spray head 7, an adjustment unit and two cleaning brushes. The clamping unit includes a lifting member 8, a U-shaped plate 9, two clamping members 10, two clamping plates 11 and two heaters 12.

The cleaning assembly further includes a water supply unit. The water supply unit includes a water supply tank 31, a water pump 32 and a water pipe 33. The cleaning brush includes a fixed electromagnet 34, a movable electromagnet 35, an internal skeleton 36, a sponge 37 and a plurality of cleaning soft strips 38.

[0031] Among them, the bracket 2 is arranged below the box body 1, the conveyor 3 is arranged on the bracket 2, the clamping unit is arranged on the box body 1, the air inlet unit is arranged on the inner side wall of the box body 1, the formaldehyde detector 4 is arranged on one side of the box body 1, a building material 5 is arranged inside the clamping unit, the ventilation pipe 6 is communicated with the upper part of the box body 1, the adjustment unit is arranged inside the box body 1, the two cleaning brushes are symmetrically arranged on the adjustment unit, and the spray head 7 is arranged inside the box body 1 and is located above the two cleaning brushes. The building material 5 is conveyed to the lower part of the box body 1 through the conveyor 3, and then the clamping unit clamps it into the box body 1. At this time, the air inlet unit sucks the air around the building material 5 up into the formaldehyde detector 4, and then formaldehyde detection is carried out. After the detection is completed, the building material 5 is removed. At this time, the adjustment unit drives the cleaning brush to move, and the spray head 7 sprays clean water to wet the cleaning brush, so as to clean the air inlet unit and the clamping unit. In addition, during cleaning, the internal air can also be discharged through the ventilation pipe 6 to play a ventilation role and improve the formaldehyde purification efficiency.

[0032] Secondly, the lifting component 8 is arranged above the box body 1. The output end of the lifting component 8 penetrates through the box body 1 and is fixedly connected to the U-shaped plate 9. Two clamping components 10 are symmetrically arranged on the U-shaped plate 9. The output ends of the two clamping components 10 both penetrate through the U-shaped plate 9 and are respectively fixedly connected to the corresponding clamping plates 11. Two heaters 12 are sequentially arranged on the inner top wall of the U-shaped plate 9. The building material 5 is clamped between the two clamping plates 11. The lifting component 8 is a cylinder, and the clamping component 10 is a cylinder. The lifting component 8 drives the U-shaped plate 9 to move downward, and then the clamping component 10 is started to drive the clamping plate 11 to move, so as to clamp and fix the building material 5 on the conveyor 3. At this time, the heater 12 is started to heat the building material 5 to accelerate the emission rate of formaldehyde.

[0033] Meanwhile, the air inlet channel 13 is arranged inside the box body 1. The formaldehyde detector 4 is communicated with the air inlet channel 13. The rotating component 14 is arranged on one side of the air inlet channel 13. The output end of the rotating component 14 is located inside the air inlet channel 13. A plurality of rotating plates 15 are sequentially arranged around the output end of the rotating component 14. The rotating component 14 is a motor. When the rotating component 14 is started, it drives the rotating plate 15 to rotate, so as to convey the air in the area of the building material 5 into the formaldehyde detector 4 for detection.

[0034] In addition, the adjustment groove 18 is provided on the inner side wall of the box body 1. Two screw rods 16 are symmetrically arranged inside the adjustment groove 18. The screw rod driving member 17 is arranged on one side of the adjustment groove 18 and is fixedly connected to the corresponding screw rod 16. Two moving blocks 19 are respectively adapted to the corresponding screw rods 16. Two rotating members 20 are respectively arranged on the corresponding moving blocks 19. Two telescopic members 21 are respectively fixedly connected to the rotating ends of the corresponding rotating members 20. The output ends of the two telescopic members 21 are respectively fixedly connected to the corresponding cleaning brushes. The placement groove 22 is arranged below the adjustment groove 18. The screw rod driving member 17 is a motor, the rotating member 20 is a self-locking motor, and the telescopic member 21 is a cylinder; when cleaning is required, since the two screw rods 16 are symmetrically arranged and connected as a whole, the screw rod driving member 17 is started to drive the two moving blocks 19 to move relatively, adjusting the position spacing between the two telescopic members 21 and the two cleaning brushes. At the same time, the telescopic member 21 is started to approach the U-shaped plate 9. At the same time, the lifting member 8 is started to drive the U-shaped plate 9 to adjust the height. Thus, the cleaning brush continuously contacts the inner wall and the outer wall of the U-shaped plate 9 to obtain a cleaning effect. Then, the telescopic member 21 continues to drive the cleaning brush into the air inlet passage 13, and the rotating plate 15 is cleaned by the left and right movement of the cleaning brush; at the same time, the unused cleaning brush is placed in the placement groove 22. After one cleaning, the rotating member 20 is started to drive the cleaning brush to rotate downward, so that the used cleaning brush is placed in the placement groove 22, and then a new one is installed and used continuously, without manual replacement, improving the cleaning efficiency and the formaldehyde detection efficiency.

[0035] Then, the two sealing units are symmetrically arranged below the box body 1, the valve 23 and the exhaust fan 24 are sequentially arranged on the ventilation pipe 6, the sewage collection box 25 is arranged on the bracket 2, and the two door panels 26 are rotatably connected to the other side of the box body 1; the sealing plate 28 has an inclined groove 29 and a drainage groove 30, the sealing member 27 is arranged at one end of the box body 1, the output end of the sealing member 27 is fixedly connected to the sealing plate 28, and the sewage collection box 25 is located below the drainage groove 30. After the valve 23 and the exhaust fan 24 are opened, the internal air can be discharged from the box body 1, the sewage generated by cleaning flows into the drainage groove 30 through the inclined groove 29, then flows out from the drainage groove 30 and is collected by the sewage collection box 25. When it is necessary to replace multiple cleaning brushes inside the placement groove 22 at the same time, the door panel 26 can be opened for operation; during formaldehyde detection, the sealing member 27 is started to drive the sealing plate 28 to move, and at the same time the valve body is closed, thereby closing the box body 1 to prevent the formaldehyde concentration emitted by the building material 5 from decreasing, resulting in a decrease in detection accuracy.

[0036] Again, the water supply unit is arranged above the box body 1; the water supply tank 31 is placed above the box body 1, the water pump 32 is arranged inside the water supply tank 31, the water outlet end of the water pump 32 is communicated with one end of the water pipe 33, and the other end of the water pipe 33 penetrates through the box body 1 and is communicated with the spray head 7. The water supply tank 31 can store clean water for cleaning. When the water pump 32 is started, water is pumped into the water pipe 33 and then sprayed out from the spray head 7.

[0037] Moreover, the fixed electromagnet 34 is fixedly connected to the output end of the telescopic member 21, the movable electromagnet 35 is attracted to the fixed electromagnet 34, the internal skeleton 36 is arranged on the movable electromagnet 35, the sponge 37 is arranged outside the internal skeleton 36, and multiple cleaning soft strips 38 are sequentially arranged outside the sponge 37. The fixed electromagnet 34 and the movable electromagnet 35 are energized and then attracted to each other to complete the installation of the cleaning brush. When it is necessary to disassemble, the two electromagnets are powered off. At the same time, the internal skeleton 36 supports the sponge 37 to improve the structural strength and prevent the sponge 37 from being too soft to effectively clean when contacting and scrubbing the U-shaped plate 9 and the rotating plate 15; at the same time, after the sponge 37 absorbs water and cooperates with the continuous contact of the cleaning soft strips 38, it can better clean the U-shaped plate 9, the rotating plate 15 and the air inlet channel 13, greatly improving the cleaning effect.

[0038] When using a formaldehyde detection device for building materials according to this embodiment, the building material 5 is conveyed under the box body 1 through the conveyor 3, and then the clamping unit clamps it into the box body 1. At this time, the air inlet unit sucks the air around the building material 5 into the formaldehyde detector 4 for formaldehyde detection. After the detection is completed, the building material 5 is removed. At this time, the adjusting unit drives the cleaning brush to move, and the nozzle 7 sprays clear water to wet the cleaning brush, so as to clean the air inlet unit and the clamping unit. Through the above structural settings, the clamping unit that directly contacts the building material 5 is cleaned, and at the same time, the air inlet unit where the formaldehyde air mainly flows is cleaned. With the spraying of clear water, the air in the box body 1 can also be purified, effectively removing residual formaldehyde, and greatly improving the detection accuracy of the subsequent building material 5.

[0039] The above-disclosed are only one or more preferred embodiments of the present application, and the scope of rights of the present application cannot be limited thereby.
