Description

Technical Field

[0001] This invention relates to the field of formaldehyde detection technology, specifically a high-efficiency formaldehyde detection device for furniture production. Background Technology

[0002] Formaldehyde is a colorless gas that is not easily detected at low concentrations and can be easily masked by other odors, such as those found in air fresheners. At higher concentrations, it has a strong, irritating, and suffocating odor and can irritate the eyes and nose. Formaldehyde is currently a toxic gas that seriously endangers human health and is frequently found in substandard furniture and decoration materials.

[0003] Most formaldehyde currently comes from paints and furniture used during renovations. Furniture typically undergoes formaldehyde testing during production to inform its treatment. However, while existing formaldehyde testing equipment can quickly and effectively detect formaldehyde levels in the air, it still has significant shortcomings in practical use, such as: During furniture production, formaldehyde testing in the factory area simply involves installing a detector to measure formaldehyde levels in the air. However, as is well known, furniture, such as cabinets, is typically assembled from several boards. Besides raw wood, most existing boards are composite, made by bonding wood chips and various materials with chemical adhesives and then painting the surface. The real source of formaldehyde emission is the chemical adhesives and paint. The best way to reduce formaldehyde emissions in current furniture manufacturing processes is to use strong seals at the edges of the boards to minimize evaporation. However, existing testing methods and equipment are clearly inefficient and inaccurate in detecting formaldehyde in different types of boards used in furniture production. This results in finished furniture still having a high level of formaldehyde volatility due to the uncertainty of individual boards. Therefore, a high-efficiency formaldehyde testing device for furniture production is now being designed to address this deficiency. Summary of the Invention

[0013] Preferably, both sides of the cylinder surface are fixedly connected to a folded pressure plate for use with a movable bending frame via a fixing plate, and an arc-shaped pressure column for use with a first button is fixedly installed on the top of the folded pressure plate.

[0014] This invention provides a high-efficiency formaldehyde detection device for furniture production. Compared with existing technologies, it has the following advantages: (1) This high-efficiency furniture production formaldehyde detection equipment combines a formaldehyde detection mechanism and a heating and air extraction mechanism. The combination of these two mechanisms allows the cylinder to push the protective frame down. By coordinating the structures, several rectangular extraction tubes are positioned directly at the edge of the board body, and air is extracted from it. The formaldehyde volatile content at the edge of the board body is detected by the formaldehyde detector body. At the same time, the heating of the electric heating plate can also effectively detect the concentration curve of formaldehyde emission after the board body is heated. Thus, the formaldehyde volatile qualification of each board body can be detected quickly and accurately. After the detection cylinder drives the protective frame to rise, the L-shaped plug can be connected to the rectangular extraction tube to release nitrogen to remove residual formaldehyde inside the rectangular extraction tube and the second air tube, ensuring the accuracy of subsequent detection.

[0015] (2) This high-efficiency furniture production formaldehyde detection equipment has a rectangular vertical box installed on the top of the protective frame, and gears, a first toothed plate and a second toothed plate are set inside it. It is used in conjunction with the pressure rod. After the electric heating plate contacts the board body, the continuous descent of the protective frame causes the first toothed plate to drive the gear to rotate, and the second toothed plate to drive the pressure rod to descend faster and more evenly on the basis of the original descent of the protective frame. Since the rectangular suction tube is flush with the bottom of the electric heating plate, after the bottom end of the pressure rod contacts the pressure plate, the suction end of the rectangular suction tube will be located at the middle of the edge of the board body. The subsequent compression of the moving bending frame by the folding pressure plate further adjusts the distance between the second air tube and the board body. The detection is carried out from the volatilization point of the formaldehyde in the board, which effectively improves the accuracy of the detection and ensures the safety of furniture production.

[0016] (3) This high-efficiency furniture production formaldehyde detection equipment uses an L-shaped plug installed on the inner side of a rectangular flat frame with an arc-shaped frame, and is used in conjunction with an arc-shaped pressure column and a first button. The structure allows the inclined pressure plate to squeeze the arc-shaped frame and push the L-shaped plug to connect with the rectangular tube when the rectangular flat frame is reset after the detection is completed. After rising to the top, the arc-shaped pressure column presses the first button, causing the solenoid valve tube to release a small amount of nitrogen gas, thereby removing the formaldehyde remaining in the rectangular tube, multi-head pipe and the second gas pipe, ensuring the accuracy of subsequent detection of other board materials.

[0017] (4) This high-efficiency furniture production formaldehyde detection equipment is used by installing an electric heating plate at the bottom of a rectangular flat frame, in conjunction with the formaldehyde detector body and the air pump. The structure can use the electric heating plate to gradually heat the board body within a fixed time, and the air pump can draw air into the gas collection box at different times, so that the formaldehyde detector body can detect the formaldehyde volatilization state in the board body at different temperatures. The exhaust groove can ensure that the internal air is always discharged and formaldehyde gas will not accumulate. Attached Figure Description

The first air pipe 216 is a flexible tube. One end of the first air pipe 216 passes through the rectangular flat frame 207, the protective outer frame 205 and the detection box 101 in sequence and is connected to the solenoid valve pipe 104. An electric heating plate 233 is fixedly connected to the bottom of the rectangular flat frame 207.

Two multi-ended pipes 220 are located at the front and rear of the protective frame 205, respectively. A rectangular pull tube 221 is fixedly connected to the bottom of each multi-ended pipe 220. Half the height of the rectangular pull tube 221 is parallel to the bottom of the electric heating plate 233 and presses against the vertical rod 232. The bottom end is parallel to the bottom of the rectangular suction tube 221, and several rectangular suction tubes 221 are provided. One end of the rectangular suction tube 221 is located inside the L-shaped plug 213. A front stop rod 222 is installed on one side of the rectangular suction tube 221. A second button 223 is fixedly installed on the end of the front stop rod 222 near the protective frame 205, and the second button 223 is flush with the end of the rectangular suction tube 221 near the protective frame 205.

The trachea 224 is a flexible tube, and one end of the second trachea 224 passes through the detection box 101 and is connected to the air inlet of the air pump 106. Rectangular vertical boxes 225 are fixedly connected to both sides of the top of the protective outer frame 205. Gears 226 are rotatably connected to the inner wall of the rectangular vertical box 225 via bearing components. First toothed plates 227 are fixedly connected to both sides of the top of the rectangular flat frame 207, and the top of the first toothed plates 227 passes through the protective outer frame 205 and the rectangular vertical box 225 sequentially and extends into the rectangular vertical box 225. Inside the rectangular vertical box 225, a guide side opening 228 is provided on the side away from the pressure cylinder 202. A Y-shaped slide 229 is slidably installed on the inside of the guide side opening 228. A second toothed plate 230 is fixedly connected to one end of the Y-shaped slide 229 located inside the rectangular vertical box 225. Both the second toothed plate 230 and the first toothed plate 227 mesh with the gear 226. The first toothed plate 227, the second toothed plate 230, and the gear 226 are pre-adjusted to be only twice as fast as the descent speed of the cylinder 201. Both sides of the front and rear of the protective frame 205 are fixedly connected to the circular guide cylinder 231 by brackets. The front and rear ends of the Y-shaped slide 229 are fixedly connected to the pressing vertical rod 232, and the pressing vertical rod 232 is slidably installed on the inner side of the circular guide cylinder 231. Both sides of the surface of the cylinder 201 are fixedly connected to the folded pressure plate 234 that cooperates with the movable bending frame 218 by fixing plates. The top of the folded pressure plate 234 is fixedly installed with the arc head pressure column 235 that cooperates with the first button 110.

[0023] In use, first place the plate body 4 in the middle position at the top of the conveying mechanism 3, then start the conveying mechanism 3 to move the plate body 4 into the detection box 101. Then start the cylinder 201 to descend. The descent of the cylinder 201 will support the pressure cylinder 202, the protective outer frame 205 and the rectangular flat frame 207 to descend synchronously. After the protective outer frame 205 descends, the inclined pressure plate 109 will be pulled out from the inside of the rectangular flat frame 207 and the protective outer frame 205 through the pressure port 209. After the inclined pressure plate 109 is pulled out from the inside of the rectangular flat frame 207, it will no longer squeeze the bow frame 215. At this time, the third spring 214 pushes the bow frame 215 to drive the L-shaped plugs 213 on both sides to move towards each other, thereby exposing one end of the rectangular tube 221 until the electric heating is activated. After plate 233 contacts the top of plate body 4, the circular pressure plate 203 compresses the first spring 204, which in turn presses the top of the protective frame 205, causing the protective frame 205 to continue descending, along with the circular guide cylinder 231 and the pressing vertical rods 232. However, the rectangular flat frame 207 remains stationary. Therefore, the first toothed plate 227, being in an upward state, drives the gear 226 to rotate. The rotation of the gear 226 then drives the second toothed plate 230, the Y-shaped slide 229, and several pressing vertical rods 232 to descend synchronously. Since the pressing vertical rods 232 themselves descend with the protective frame 205, the gear 226 drives the pressing vertical rods 232 to descend steadily at twice the speed of the protective frame 205 until the pressing vertical rods... When cylinder 232 descends and abuts against the top of the pressure plate 102, gear 226 stops rotating. At this time, the protective frame 205 stops descending due to the stopping of the pressure bar 232 and gear 226. The rectangular tube 221 is located between the bottom of the electric heating plate 233 and the pressure bar 232, and the rectangular tube 221 is also located in the middle of both sides of the plate body 4. Then, as cylinder 201 continues to descend, it will press the two folded pressure plates 234 to descend synchronously. At this time, the folded pressure plates 234 squeeze the moving bending frame 218, which drives several rectangular tubes 221 to move closer to the plate body 4 until the second button 223 touches the plate body 4 and is triggered, stopping cylinder 201. At this time, one end of the rectangular tube 221 is in contact with the plate body 4. The gap at the edge of the material body 4 is reduced, and then the air pump 106 and the electric heating plate 233 are started at the same time. At this time, the air pump 106 uses the second air pipe 224, the multi-head pipe 220 and the rectangular suction pipe 221 to draw air from the edge of the material body 4 and then send the air into the air collection box 105. At this time, the formaldehyde detector body 107 detects the formaldehyde concentration of the injected air, while the electric heating plate 233 heats the material body 4 for one minute, so that the temperature of the material body 4 gradually rises within one minute. Meanwhile, the rectangular suction pipe 221 continuously draws air from the edge of the material body 4 within one minute, so that the formaldehyde detector body 107 can detect the emission concentration trend of formaldehyde after the material body 4 is heated within one minute. After the test is completed, cylinder 201 is activated to rise. Cylinder 201 will first drive the two folded pressure plates 234 to rise synchronously and stop pressing the moving bending frame 218. At this time, several rectangular tubes 221 move away from the plate body 4 under the elastic force of the fourth spring 219 and return to their original positions. Then, as the protective frame 205 rises, it will drive the first toothed plate 227 to fall, causing the gear 226 to rotate in the opposite direction, driving the second toothed plate 230 and several pressing vertical rods 232 to rise and return to their original positions. Then, the protective frame 205 pulls the rectangular flat frame 207 to rise synchronously, causing the electric heating plate 233 to detach from the plate body 4, until the protective frame... When 205 rises to the top, the bottom end of the inclined pressure plate 109 passes through the pressure socket 209 and squeezes the bow-shaped frame 215, thereby causing the front and rear L-shaped plugs 213 to move in opposite directions. Then, the L-shaped plugs 213 cover the suction end of the rectangular suction tube 221. When the protective outer frame 205 rises to the top, the two arc-head pressure columns 235 press the first button 110 to activate the solenoid valve tube 104 to release a small amount of nitrogen. After the nitrogen enters the rectangular suction tube 221, the multi-head pipe 220 and the second air pipe 224, it eliminates the residual formaldehyde inside, ensuring that the subsequent testing of the board body 4 to be tested can be more accurate.
