Technical Field

[0001] This utility model relates to the field of coating production equipment technology, specifically a dust removal device for coating lines. Background Technology

[0002] In the coating process, the cleanliness of the workpiece surface is one of the key factors that determines the final coating quality. Even tiny dust, fibers or particles adhering to the workpiece surface can lead to quality defects such as pitting, particles, and pinholes after coating, which seriously affect the product's appearance, corrosion resistance and service life. Therefore, effective surface dust removal must be carried out before the workpiece enters the spray booth or coating room.

[0003] In the prior art, patent publication number CN117399336A discloses a dust removal device for easy cleaning of internal dust accumulation during coating processes. The device includes a conveyor frame with a working box fixedly installed at the top center. The working box has a rectangular cavity structure, and a dust collection hood is fixedly installed near the top inside the working box. A first mounting frame and a second mounting frame are fixedly installed inside the working box, arranged symmetrically front to back, and located below the dust collection hood. A cleaning roller is provided on the first mounting frame, corresponding to the conveyor roller of the conveyor frame. An adjusting seat is provided on the second mounting frame. A rotating sleeve is rotatably mounted on the adjusting seat. A scraper is provided below the rotating sleeve, corresponding to the conveyor roller of the conveyor frame.

[0004] This type of dust removal equipment for coating lines, which is easy to clean internal dust accumulation, has the following disadvantages: it cleans the surface of the object to be coated by rotating the cleaning roller and contacting the scraper with the object to be coated, respectively. However, the impurities after cleaning may stick to the surface of the cleaning roller or scraper, causing secondary pollution. Therefore, we propose a dust removal device for coating lines.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This embodiment provides a technical solution: a dust removal device for a coating line, including a coating chamber 1, a dust removal chamber 2 fixedly connected to the left side of the upper surface of the coating chamber 1, a material conveying pipe 11 fixedly connected to the upper side of the interior of the coating chamber 1, nozzles 12 symmetrically distributed on the left and right sides fixedly connected to the lower surface of the material conveying pipe 11, a control switch group 13 is provided outside the coating chamber 1, the input end of the control switch group 13 is electrically connected to an external power supply, an exhaust port 6 is opened on the upper surface of the coating chamber 1, a fan 7 is fixedly connected inside the exhaust port 6, the input end of the fan 7 is electrically connected to the output end of the control switch group 13, connecting the external paint conveying pipe to the material conveying pipe 11, so that the paint is sprayed from the lower side of the nozzle 12 to the surface to be sprayed on the object to be sprayed through the material conveying pipe 11, and the control switch group 13 is operated to start the fan 7, so that the gas inside the coating chamber 1 is discharged through the exhaust port 6, and a dust removal mechanism 8 is also included.

[0022] Dust removal mechanism 8 includes a blowing duct 81, an exhaust duct 82, a hollow rotating drum 83, through holes 84, brush bristles 85, and a rotary joint 87. The blowing duct 81 is fixedly connected to the left side of the upper inner surface of the dust removal chamber 2. The exhaust duct 82 is fixedly connected to the middle of the upper inner surface of the dust removal chamber 2. The rotary joint 87 is fixedly connected to the rear surface of the dust removal chamber 2. The hollow rotating drum 83 is fixedly connected to the front side of the rotating end of the rotary joint 87. The outer surface of the hollow rotating drum 83 has evenly distributed through holes 84. Evenly distributed brush bristles 85 are fixedly connected to the outer surface of the hollow rotating drum 83 (the hollow rotating drum 83 can be disassembled periodically for deep cleaning of the brush bristles 85). The dust removal mechanism 8 also includes a motor 86, which is fixedly connected to the front surface of the dust removal chamber 2. The rear end of the output shaft of motor 86 is fixedly connected to the front surface of hollow drum 83. The input end of motor 86 is electrically connected to the output end of control switch group 13. The object to be sprayed continues to move to the right to the lower side of hollow drum 83. The rotation of hollow drum 83 drives brush bristles 85 to rotate around the central axis of hollow drum 83 (the central axis of the rotating end of rotary joint 87, the central axis of hollow drum 83, and the central axis of output shaft of motor 86 coincide), cleaning the surface of the object to be sprayed, thereby removing stubborn impurities from the surface of the object to be sprayed. At the same time, since hollow drum 83 is connected to dust collection box 3, negative pressure is also generated inside hollow drum 83, which causes stubborn impurities brushed off by brush 85 to be sucked into the hollow drum through through hole 84. Inside the rotary drum 83, stubborn impurities then enter the dust collection box 3 through the rotary joint 87 and ventilation duct, thus cleaning the surface of the object to be sprayed. The dust collection box 3 is fixedly connected to the upper surface of the coating chamber 1. A filter screen 4 is inserted inside the dust collection box 3 (the filter screen 4 can be pulled out from inside the dust collection box 3 for cleaning, preventing dust from clogging it after prolonged use). An exhaust port 5 is fixedly connected to the upper surface of the dust collection box 3. The upper end of the fixed end of the rotary joint 87 and the upper side of the exhaust duct 82 are both connected to the lower side of the interior of the dust collection box 3 through ventilation ducts. Excess air is drawn out from the exhaust port 5 through the filter screen 4, which filters the dust in the air, causing the dust to remain inside the dust collection box 3. (Operation control...) The switch group 13 is activated, starting motor 86. The output shaft of motor 86 rotates, driving the hollow drum 83 to rotate. The air inlet at the upper end of the air duct 81 is connected to the air outlet of the external blower, and the exhaust port 5 is connected to the air inlet of the external exhaust device. This causes air to be blown inside the air duct 81 of the external blower, blowing air out from the lower side of the air duct 81 (the lower side of the air duct 81 is a rectangular slot facing to the right). When the object to be sprayed moves to the lower side of the air duct 81, the lower side of the air duct 81 blows air onto the surface of the object to be sprayed, thus removing the floating dust from the surface. Simultaneously, because the airflow direction is to the right, the floating dust moves to the right with the airflow into the interior of the exhaust duct 82.The external ventilation system creates negative pressure inside the dust collection box 3 and the ventilation duct 82, thereby drawing the air and dust blown out of the blowing duct 81 into the ventilation duct 82. The dust then enters the lower interior of the dust collection box 3 through the ventilation duct.

[0023] Rotating rollers are rotatably connected to both the left and right sides of the interior of the coating chamber 1. The two rotating rollers are connected by a conveyor belt 9. A motor 2 10 is fixedly connected to the left side of the front surface of the coating chamber 1. The rear end of the output shaft of the motor 2 10 is fixedly connected to the front end of the left rotating roller. The input end of the motor 2 10 is electrically connected to the output end of the control switch group 13. The object to be coated is placed on the left side of the upper surface of the conveyor belt 9. The control switch group 13 is operated to start the motor 2 10. The output shaft of the motor 2 10 rotates, driving the left rotating roller to rotate, causing the conveyor belt 9 to move, thereby conveying the object to be coated.

[0024] The working principle of the dust removal device for a coating line provided by this utility model is as follows: When using this dust removal device for coating line dust removal operations, place the object to be coated on the left side of the upper surface of the conveyor belt 9, operate the control switch group 13 to start the second motor 10, the output shaft of the second motor 10 rotates and drives the left rotating roller to rotate, so that the conveyor belt 9 moves and thus conveys the object to be coated. Operate the control switch group 13 to start the first motor 86, so that the output shaft of the first motor 86 rotates and drives the hollow rotating drum 83 to rotate, connecting the air inlet at the upper end of the blowing trough 81 to the air outlet of the external blower, and connecting the exhaust port 5 to the external exhaust equipment. The air inlet is connected, causing air to be blown inside the external blower box 81. Air is blown out from the lower side of the blower box 81 (the lower side of the blower box 81 is a rectangular slot facing right). When the object to be sprayed moves to the lower side of the blower box 81, air is blown from the lower side of the blower box 81 onto the surface of the object to be sprayed, thus removing the floating dust from the surface. Simultaneously, because the airflow direction is to the right, the floating dust moves to the right with the airflow into the exhaust duct 82. The external exhaust system creates a negative pressure inside the dust collection box 3 and the exhaust duct 82, thereby drawing in the air and floating dust blown out of the blower box 81. Inside the exhaust duct 82, floating dust enters the lower part of the dust collection box 3 through the ventilation duct. Excess air is drawn out from the exhaust port 5 through the filter screen 4. The filter screen 4 filters the dust in the air, causing the dust to remain inside the dust collection box 3. Then, the object to be sprayed continues to move to the right to the lower side of the hollow rotating drum 83. The rotation of the hollow rotating drum 83 drives the brush bristles 85 to rotate around the central axis of the hollow rotating drum 83 (the central axis of the rotating end of the rotating joint 87, the central axis of the hollow rotating drum 83, and the central axis of the output shaft of the motor 86 coincide), cleaning the surface of the object to be sprayed, thereby removing the surface of the object to be sprayed. Stubborn impurities on the surface are removed. Since the hollow rotating drum 83 is connected to the dust collection box 3, a negative pressure is generated inside the hollow rotating drum 83. This causes the stubborn impurities brushed off by the brush 85 to be sucked into the interior of the hollow rotating drum 83 through the through hole 84. Then, the stubborn impurities enter the interior of the dust collection box 3 through the rotary joint 87 and the ventilation duct, thereby cleaning the surface of the object to be sprayed. The external paint delivery pipe is connected to the material delivery pipe 11, so that the paint is sprayed from the lower side of the nozzle 12 to the surface of the object to be sprayed through the material delivery pipe 11. The control switch group 13 is operated to start the fan 7, so that the gas inside the coating chamber 1 is discharged through the exhaust port 6.

[0025] It is worth noting that the fan 7 disclosed in the above embodiments can be DTF-200, the motor 86 can be YVF2-711-2-B34, the motor 10 can be YVF2-802-2-B34, and the control switch group 13 is provided with control buttons that correspond one-to-one with the fan 7, the motor 86 and the motor 10 and are used to control their switching.

[0026] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
