Description

Technical Field

[0001] The present application relates to the field of powder spraying processing lines, and in particular to a dust suction device for powder spraying processing lines. Background Art

[0002] The powder spraying processing line is an automated equipment used to produce powder coatings or paints. It is mainly composed of a feeder, a storage tank, a metering pump, a conveyor and a spray gun. In the powder spraying processing line, when the workpiece enters the spraying room, the feeder rotates to evenly deliver the powder to the part to be sprayed. Under the action of high pressure, the powder is atomized into particles and sprayed onto the surface of the workpiece. At the same time, the powder will drift down from a high place with the airflow, making the entire coating uniform. In addition, the powder spraying processing line also includes two parts: the front transmission part and the rear feeding mechanism. The powder spraying processing line often uses a dust suction structure to recover the sprayed dust to avoid dust pollution to the surrounding environment. When the conventional powder spraying structure is used, after the powder spraying box is installed stably, the connecting box is installed on the surface of the powder spraying box. One end of the connecting box is connected to the negative pressure fan with the help of a connecting pipe, so as to recover the dust in the powder spraying box, and a shielding frame is installed on the inner wall of the connecting box to shield larger objects with the help of the shielding frame.

[0003] With respect to the above-mentioned related technologies, the inventors believe that, after a period of use, conventional dust recovery structures often need to clean the connection box to avoid dust clogging the dust suction structure. During the cleaning, the machine needs to be shut down, which causes the machine to be unable to be put into use during the cleaning, resulting in reduced powder spraying processing efficiency.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0021] The present application embodiment discloses a dust collecting device for a powder spraying processing line, referring to Figure 1-Figure 2, including a powder spray box 1. When in use, after the powder spray box 1 is installed stably, two connecting boxes 2 are installed on the surface of the powder spray box 1. One end of the connecting box 2 is connected to the negative pressure fan by means of a connecting pipe 3, so as to recover the dust in the powder spray box 1. A shielding frame 4 is installed on the inner wall of the connecting box 2. With the help of the shielding frame 4, larger objects are shielded. The connecting frame 5 is installed on the surface of the powder spray box 1. The inner wall of the connecting frame 5 is provided with a plurality of card slots 6. The inner wall of the card slot 6 is clamped with a limiting block 7. One end of the limiting block 7 is fixedly connected to one end of the connecting box 2. The connecting frame 5 is connected to the inner wall of the card slot 6. Two rotating buckles 8 are rotatably installed at one end of the box 2, and the surface of the rotating buckle 8 is clamped with the inside of the powder spray box 1, so as to fix the connecting box 2 to the surface of the powder spray box 1. After the rotating buckle 8 and the surface of the powder spray box 1 are removed, and the limit block 7 is separated from the card slot 6, the connecting box 2 is removed from the surface of the powder spray box 1, so that when the connecting frame 5 on one side is cleaned, the dust is sucked through the connecting box 2 on the other side to avoid affecting the use of the powder spray processing line. The surface of the connecting pipe 3 is slidably connected with an adjusting pipe 9, which is convenient for disassembling the connecting box 2 at one end of the connecting pipe 3.

[0022] Reference Figure 2-Figure 3 A baffle plate 10 is slidably installed on the inner wall of the connection box 2, and a connecting hole 11 is opened on the inner wall of the baffle plate 10. The inner wall of the connecting hole 11 is slidably connected to the surface of the baffle frame 4, so as to improve the stability of the baffle plate 10. With the help of the baffle plate 10, the connection box 2 is disassembled to block and prevent the dust in the powder spray box 1 from floating out. A fixing frame 12 is slidably installed on the inner wall of the baffle plate 10, and one end of the fixing frame 12 is welded to the surface of the powder spray box 1. With the help of the fixing frame 12, the baffle plate 10 is convenient to be folded up when it is not needed, and the baffle plate 10 is kept installed on one side of the connection box 2, which is more convenient when the connection box 2 needs to be disassembled.

A motor 15 is fixedly installed on the top of the fan blade 14. The fan blade 14 is controlled to rotate by means of the motor 15, so that a negative pressure wind flow is formed at one end of the bellows 13 to suck in the dust near the entrance of the powder spray box 1, effectively preventing the dust from spreading outward. Several shielding plates 16 are installed at one end of the powder spray box 1. The shielding plates 16 are used to shield one end of the powder spray box 1 to prevent the wind flow formed by the bellows 13 from blowing the dust out from the other end of the powder spray box 1, effectively ensuring the dust shielding effect of the powder spray box 1.

In order to affect the use of the powder processing line, a baffle plate 10 is slidably installed on the inner wall of the connecting box 2, and a connecting hole 11 is opened on the inner wall of the baffle plate 10. The inner wall of the connecting hole 11 is slidably connected to the surface of the baffle frame 4, so that the baffle plate 10 can be used to block the powder in the powder spray box 1 after the connecting box 2 is disassembled to prevent the powder in the powder spray box 1 from floating out. A fixing frame 12 is slidably installed on the inner wall of the baffle plate 10, and one end of the fixing frame 12 is welded to the surface of the powder spray box 1, so that the baffle plate 10 can be folded up when not in use with the help of the fixing frame 12, which is more convenient when in use.

[0025] Two bellows 13 can also be installed at one end of the powder spray box 1. The inner wall of the bellows 13 is rotatably connected to a fan blade 14, and a motor 15 is fixedly installed on the top of the fan blade 14, so that the fan blade 14 can be rotated by means of the motor 15, so that a negative pressure wind flow is formed at one end of the bellows 13, which effectively prevents the dust from spreading outward. Several shielding plates 16 are installed at one end of the powder spray box 1, so that one end of the powder spray box 1 can be shielded by means of the shielding plates 16 to prevent the wind flow formed by the bellows 13 from blowing the dust out from the other end of the powder spray box 1.
