Description

Technical Field

[0001] This utility model relates to the field of dust removal technology for sheet metal, and more specifically, it relates to a dust removal device for sheet metal. Background Technology

[0002] Furniture panels are typically installed on interior walls, serving both protective and decorative functions. During production, the surface of the panel substrate must first be sanded before subsequent processing, such as painting or lamination. Because sanding generates a significant amount of dust and debris, and some impurities easily adhere to the panel surface, thorough cleaning and dust removal are essential after sanding. Residual dust or foreign matter on the surface will directly affect the painting and lamination results, causing quality defects and impacting the finished product's pass rate.

[0003] Currently, common methods for cleaning board surfaces mainly include air blowing and adsorption. While the former is simple to operate, it directly disperses dust and impurities into the air, severely polluting the working environment and causing a decline in air quality. In the long run, this poses a significant threat to the respiratory health of on-site workers. Furthermore, existing dust removal equipment mostly uses cleaning rollers with fixed spacing. Since the actual thickness of the boards to be treated varies, when encountering thicker boards, if the gap between the cleaning rollers is not adjusted accordingly, excessive pressure will be applied to the board surface. This not only weakens the dust removal effect but also easily causes irreversible scratches and defects on the board surface.

[0004] In view of this, we propose a dust removal device for sheet metal. Utility Model Content

[0005] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a dust removal device for sheet metal to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a dust removal device for sheet metal, comprising support legs, two crossbeams fixedly connected between the support legs, conveying rollers rotatably connected between the two crossbeams at equal intervals, a cleaning roller one connected to a gate between the two crossbeams, dust collection shells fixedly connected to the upper and lower sides of the two crossbeams, dust collection shells fixedly connected to and connected to a suction pipe, connecting members slidably connected to both sides of the upper dust collection shell, a cleaning roller two rotatably connected between the two connecting members, the cleaning roller two being located above the cleaning roller one, the upper dust collection shell being provided with a through groove, the cleaning roller two sliding within the through groove of the dust collection shell, and the upper dust collection shell being provided with a thickness measuring structure and a limiting structure.

[0007] The present invention is further configured such that two fixing blocks are fixedly connected to the dust collection shell on the upper side, the fixing blocks are slidably connected to a slide rod, the slide rod is fixedly connected to an adjacent connecting member, and a spring is fixedly connected between the slide rod and the fixing blocks.

[0008] The present invention is further configured such that the thickness measuring structure includes two connecting plates, the two connecting plates are fixed to one side of the upper dust collection shell, and a sliding frame is slidably connected between the two connecting plates, and the sliding frame is rotatably connected to two rollers.

[0009] The present invention is further configured such that a folded rod is fixedly connected between the sliding frame and the connecting member.

[0010] The present invention is further configured such that the limiting structure includes two horizontal plates, the two horizontal plates are fixedly connected to the other side of the upper dust collection shell, the horizontal plates are fixedly connected to a fixing rod, a sliding frame two is slidably connected between the two fixing rods, and the sliding frame two is rotatably connected to a rubber wheel.

[0011] The present invention is further configured such that the diameters of the roller and the rubber wheel are the same as the diameter of the conveying roller.

[0012] The present invention is further configured such that the sliding frame two is fixedly connected to the connecting plate two, and the connecting plate two is fixedly connected to the wedge block.

[0013] The present invention is further configured such that two support plates are fixedly connected to the upper dust collection shell, and a pressing rod is slidably connected to the support plate. The pressing rod passes through the fixed block and abuts against the sliding rod. The pressing rod is in contact with the wedge block. A fixed plate is fixedly connected to the pressing rod, and a spring is fixedly connected between the fixed plate and the support plate.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a dust removal device for sheet metal, which has the following beneficial effects: 1. This utility model uses rollers in the thickness measuring structure to pre-contact the plate, transmitting thickness changes to the cleaning roller two via a folding rod, allowing it to automatically adjust its height according to the plate thickness. This dynamic adjustment ensures that the cleaning roller and the plate surface always maintain the optimal distance, avoiding both strong squeezing and scratches caused by too small a gap, and incomplete cleaning caused by too large a gap.

[0015] 2. When the sheet material reaches the rubber wheel, the wedge block moves upward, which in turn pushes the extrusion rod to lock the slide bar. This design prevents the cleaning roller from moving downward due to the spring action after the sheet material separates from the thickness measuring roller, ensuring a constant and stable cleaning gap during the main sheet material cleaning stage, thereby improving the consistency and reliability of the dust removal effect.

[0016] 3. This utility model features sealed dust collection shells at both the upper and lower cleaning rollers, which are directly connected to the dust extraction pipe. This structure can promptly extract and collect the dust generated during dust removal, preventing dust from spreading in the air, effectively improving the air quality at the work site, and protecting the health of operators.

[0023] Please see Figure 2 and Figure 3 The thickness measuring structure includes two connecting plates 12, which are fixed to one side of the upper dust collection shell 5. A sliding frame 13 is slidably connected between the two connecting plates 12, and two rollers 14 are rotatably connected to the sliding frame 13. A folded rod 15 is fixedly connected between the sliding frame 13 and the connecting piece 7.

[0024] Please see Figure 4 and Figure 5 The limiting structure includes two horizontal plates 16, which are fixed to the other side of the upper dust collection shell 5. A fixing rod 17 is fixed to the horizontal plate 16, and a sliding frame 18 is slidably connected between the two fixing rods 17. A rubber wheel 19 is rotatably connected to the sliding frame 18. The diameters of the roller 14 and the rubber wheel 19 are the same as the diameter of the conveying roller 3. A connecting plate 20 is fixed to the sliding frame 18, and a wedge block 21 is fixed to the connecting plate 20. Two support plates 22 are fixed to the upper dust collection shell 5. A pressing rod 23 is slidably connected to the support plate 22. The pressing rod 23 passes through the fixing block 9 and abuts against the sliding rod 10. The pressing rod 23 is in contact with the wedge block 21. A fixing plate 24 is fixed to the pressing rod 23, and a spring 25 is fixed between the fixing plate 24 and the support plate 22.

[0025] The working principle of this utility model: In use, the board is placed on the conveyor roller 3. Driven by the conveyor roller 3, the board moves from left to right. The cleaning roller 1 4 and cleaning roller 2 8 are started, and the dust suction pipe 6 is connected to the external dust collection device. After the board moves to the underside of the two rollers 14, the rollers 14 will move upward and roll along the upper side of the board. When the sliding frame 13 moves upward, the connecting piece 7 is driven upward through the two folding rods 15. The two connecting pieces 7 drive the cleaning roller to move upward along the through groove of the dust collection shell 5. The rollers 14 roll along the board, thereby adjusting the distance between the cleaning roller 1 4 and cleaning roller 2 8 so that the distance between the cleaning roller 1 4 and cleaning roller 2 8 is adapted to the thickness of the board. The board continues to move, and the cleaning roller 1 4 and cleaning roller 2 8 clean the dust on the board. The cleaned dust enters the dust collection device through the dust suction pipe 6.

[0026] After the board moves to the two rubber wheels 19, the rubber wheels 19 roll along the upper side of the board. The rubber wheels 19 drive the sliding frame 18 to slide along the fixed rod 17. The sliding frame 18 drives the wedge block 21 to move upward through the connecting plate 20. The wedge block 21 squeezes the extrusion rod 23, and the spring 25 is compressed. The extrusion rod 23 slides along the support plate 22 and squeezes and limits the sliding rod 10. Thus, when the roller 14 loses contact with the board, the cleaning roller 8 will not move downward, improving the cleaning effect of the cleaning roller 8 and the cleaning roller 4 on the board.

[0027] When the rubber roller loses contact with the board, the extrusion rod 23 is reset under the elastic force of the second spring 25. The extrusion rod 23 releases the limit on the slide rod 10. At the same time, under the elastic force of the first spring 11, the connecting piece 7 drives the cleaning roller to move downward. Through the cooperation of the roller 14 and the rubber wheel 19, the second cleaning roller 8 and the first cleaning roller 4 are suitable for boards of different thicknesses, and the distance between the second cleaning roller 8 and the upper side of the board is ensured, thereby improving the cleaning effect on the board.

For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
