Description

Technical Field

[0001] The utility model relates to the technical field of powder coating filling, in particular to a powder filling dust removal mechanism. Background Art

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigment, filler and additives, which is harmless, efficient, resource-saving and environmentally friendly. Since powder coating will generate a certain amount of dust during filling, it is necessary to use corresponding dust removal equipment to cooperate with the filling operation, such as a powder coating filling device disclosed in the Chinese utility model patent with patent publication number CN220199640U, which can avoid the dust problem during the filling process;

[0003] When the device is used, a dust shield is arranged outside the discharge pipe of the lower hopper, and then a cylinder is arranged on one side of the bottom of the lower hopper. The valve plate is pulled or pushed by the cylinder to make the dust shield slide up and down outside the discharge pipe. During filling, the dust shield moves downward to block the top of the barrel. After filling, the dust shield is reset to avoid the barrel, thereby completing dust blocking.

[0004] However, when the above-mentioned powder coating filling device is actually operated, since the baffle only blocks the dust from overflowing, it takes a certain amount of time for the powder dust in the barrel to completely settle in the barrel. At this time, if the baffle is detached from the top of the barrel, some dust will still overflow. To avoid this situation, it is necessary to extend the residence time of the barrel, but this also leads to a decrease in filling efficiency. Utility Model Content

[0024] It should be noted that the powder filling dust removal mechanism described in the utility model is used for but not limited to dust filling, etc. For the convenience of explanation, in the utility model, only a powder filling dust removal mechanism applied to dust filling is used as an example for explanation. The principle of applying a powder filling dust removal mechanism to other types of equipment is essentially the same as the principle applied to dust filling, and will not be repeated here.

[0025] See also Figure 1 - Figure 3 , Figure 1 This is a structural schematic diagram of a powder filling and dust removal mechanism in an embodiment of the utility model, a powder filling and dust removal mechanism includes a material pipe 100, an annular baffle 200, a dust collecting piece 300 and an air collecting pipe 400, the annular baffle 200 is sleeved on the outside of the material pipe 100, the dust collecting piece 300 is arranged at the bottom of the annular baffle 200, the air collecting pipe 400 is arranged at the top of the annular baffle 200, and the air collecting pipe 400 is connected with the dust collecting piece 300, and the air collecting pipe 400 is adapted to the collecting device.

[0026] In this embodiment, the material pipe 100 drives the annular baffle 200 to adapt to the top of the material barrel (the existing material storage barrel, not shown in the figure, the same below, and no further description), and then discharges the powder through the material pipe 100. When the powder is discharged from the material pipe 100, powder will float. At this time, start the existing dust collection equipment (the existing equipment, not shown in the figure, the same below, and no further description), and connect the dust collection piece 300 through the air collecting pipe 400. The dust collection piece 300 absorbs the floating dust at the bottom of the annular baffle 200 to achieve the purpose of quickly dissipating the powder.

[0027] In one embodiment, see Figure 1 - Figure 3 The top of the material pipe 100 is compatible with the existing equipment of the storage hopper, which is not shown in the figure and will be described in detail below. A fixed sleeve 110 is sleeved on the outer side of the bottom of the material pipe 100, and a link 210 is fixedly connected to the center of the ring baffle 200. The material pipe 100 is located in the link 210, and the inner wall of the link 210 is fixedly connected to a limit ring 220. The limit ring 220 is located above the fixed sleeve 110, and the inner diameter of the limit ring 220 is smaller than the outer diameter of the fixed sleeve 110. A plurality of limit strips 120 are provided on the outer side of the material pipe 100, and the limit strips 120 are located above the fixed sleeve 110. A plurality of slide grooves 221 are opened on the inner side of the limit ring 220, and the slide grooves 221 are slidably connected to the limit strips 120.

[0028] In this embodiment, when the existing filling equipment is filling, the material discharge component (such as the material pipe 100 in the present device) is generally made to descend to a certain height after being aligned with the material barrel, and then the material is discharged, so as to increase accuracy and reduce dust dispersion. That is, when the material pipe 100 descends, the annular baffle 200 descends together with the material pipe 100. When the material pipe 100 rises, the material pipe 100 drives the annular baffle 200 to rise through the fixed sleeve 110 adapted to the limit ring 220.

[0029] In one embodiment, see Figure 1 , a rubber ring 230 is provided at the outer edge of the bottom of the ring baffle 200;

[0030] In this embodiment, the rubber ring 230 is used to reduce the noise generated by the contact between the ring baffle 200 and the barrel.

[0031] In one embodiment, see Figure 1 - Figure 3The dust collecting member 300 includes a plurality of fixed tubes 310, a plurality of elastic tubes 320 and a plurality of dust collecting nozzles 330. The plurality of fixed tubes 310 are evenly arranged on the top of the annular baffle 200, and the bottom ends of the fixed tubes 310 penetrate to the bottom of the annular baffle 200. One ends of the plurality of elastic tubes 320 are respectively connected with the bottom ends of the plurality of fixed tubes 310. The plurality of dust collecting nozzles 330 are respectively installed at the other ends of the plurality of elastic tubes 320. The tops of the plurality of fixed tubes 310 are connected with the air collecting pipe 400. A pressing piece 500 is provided above the elastic tube 320. A bellows 410 is provided on one side of the air collecting pipe 400. The bellows 410 is used to connect with the collecting device.

[0032] In this embodiment, the existing collection device is connected to the air collecting pipe 400 through the bellows 410, and then the bottom of the air collecting pipe 400 is connected and fixedly connected to the top of a plurality of fixed pipes 310, and the bottom of the fixed pipe 310 is connected to the dust suction nozzle 330 through the elastic pipe 320 to absorb the dust;

[0033] The elastic tube 320 has elastic deformation performance and can complete the resetting action.

[0034] In one embodiment, see Figure 1 - Figure 3 The lower pressing member 500 includes a pressing ring 510, a sliding rod 520, a cross bar 530, a sliding ring 540 and a fixed ring 550. The pressing ring 510 is arranged above a plurality of elastic tubes 320, and the pressing ring 510 is connected to the elastic tubes 320. A plurality of sliding rods 520 are vertically arranged on the top of the pressing ring 510. The top ends of the sliding rods 520 all penetrate to the top of the ring baffle 200. The top ends of the sliding rods 520 are vertically arranged with cross bars 530. The length direction of the cross bars 530 is perpendicular to the axis direction of the material tube 100. The sliding ring 540 is slidably sleeved on the outside of the material tube 100. The outer side of the sliding ring 540 is fixedly connected to one end of the cross bar 530 that is close to each other. The fixed ring 550 is fixedly sleeved on the middle part of the material tube 100, and the fixed ring 550 is located above the sliding ring 540.

[0035] In this embodiment, when the material pipe 100 moves up and down, it will drive the fixed ring 550 to move together. When moving downward, the ring baffle 200 moves together until it contacts the top of the barrel and then stops moving. The material pipe 100 will continue to move downward for a distance. At the same time, the fixed ring 550 presses the sliding ring 540 downward, and the sliding ring 540 drives the sliding rod 520 to press the pressing ring 510 downward through the cross bar 530, so that the dust nozzle 330 on the elastic tube 320 can be tilted downward through the pressing ring 510 to ensure a better dust collection effect.

[0036] In order to better understand the present invention, the following Figures 1 to 3The technical solution of the utility model is described in detail: the material pipe 100 drives the annular baffle 200 to fit with the top of the material barrel, and then the powder is discharged through the material pipe 100. When the powder is discharged from the material pipe 100, powder will be scattered. At this time, the existing dust collection equipment is started, and the air collecting pipe 400 is connected to the air collecting pipe 400 through the air collecting pipe 400, and then the bottom of the air collecting pipe 400 is connected and fixedly connected with the top of a plurality of fixed pipes 310. The bottom of the fixed pipe 310 is connected to the dust suction nozzle 330 through the elastic pipe 320 to absorb the dust, so as to achieve the purpose of quickly dissipating the powder;

[0037] Furthermore, when the material pipe 100 moves up and down, it will drive the fixed ring 550 to move together. When moving downward, the ring baffle 200 will move together until it contacts the top of the barrel and then stop moving. The material pipe 100 will continue to move downward for a distance. At the same time, the fixed ring 550 presses the sliding ring 540 downward, and the sliding ring 540 drives the sliding rod 520 to press the pressing ring 510 downward through the cross bar 530, so that the dust suction nozzle 330 on the elastic tube 320 can be tilted downward through the pressing ring 510 to ensure a better dust suction effect.

[0038] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model.
