Description

Technical Field

[0001] The utility model relates to the field of MDF production equipment, in particular to a dust cleaning device for an MDF coating system. Background Art

[0002] Traditional powder room spraying of MDF is directly carried out in a spraying chamber. During the spraying process, a large amount of dust is generated. In the existing reverse electrode spraying, a set of iron plates is installed opposite the spray gun in the spraying chamber, and then a spray gun with a negative charge is used for spraying. In this way, reverse negative electrode operation can form an electromagnetic field between the spray gun and the object. This can reduce dust while making the spraying operation more effective and preventing powder ash from falling into the coating. However, although this reduces the impact of dust on spraying, there will still be powder ash at the bottom of the powder room. After each operation, the operator needs to use a vacuum cleaner to clean the powder ash on the internal bottom plate. During the cleaning process, the operator needs to contact the spray gun and the iron plate, which is easy to cause bruises and the dust cleaning is relatively troublesome. Content of the Utility Model

[0003] The main purpose of the utility model is to solve the problem that powder ash is easily accumulated at the bottom of the spraying chamber.

A moving track is arranged at the inner top of the spraying chamber. A speed reducer is arranged at one end of the spraying chamber. One end of the speed reducer is connected to a driving motor, and the other end is connected to the rotating collecting shaft. The other end of the rotating collecting shaft is matched with a bearing seat, and the bearing seat is installed on the inner wall at the other end of the spraying chamber. Movable bottom plates are respectively arranged on both sides of the rotating collecting shaft, and a collecting groove is arranged at the bottom of the rotating collecting shaft. The collecting groove is connected to the collecting box through a collecting pipe.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Embodiment 1: Refer to Figures 1-6 , a dust cleaning device for an MDF coating system, mainly including a spraying chamber 1, a spraying assembly 2, a moving track 3, a rotating collection shaft 4, a movable bottom plate 5 and a collection box 6. Inlets 7 and outlets 8 are respectively opened at both ends of the spraying chamber 1. Spraying assemblies 2 are respectively arranged on both sides of the spraying chamber 1. A moving track 3 is arranged at the inner top of the spraying chamber 1. A reducer 9 is arranged at one end of the spraying chamber 1. One end of the reducer 9 is connected to a drive motor 10, and the other end is connected to a rotating collection shaft 4. The other end of the rotating collection shaft 4 is matched with a bearing seat 11. The bearing seat 11 is installed on the inner wall at the other end of the spraying chamber 1. Movable bottom plates 5 are respectively arranged on both sides of the rotating collection shaft 4, and a collection groove 12 is arranged at the bottom of the rotating collection shaft 4. The collection groove 12 is connected to the collection box 6 through a collection pipeline 13.

[0023] By generating suction through the fan inside the collection groove 6, the powder ash accumulated on the rotating collection shaft 4 and the movable bottom plate 5 is sucked out through the collection grooves 12, without generating dust, replacing the problem that the traditional bottom plate cannot move and the dust cleaning is inconvenient.

[0024] Sliding grooves 14 are arranged at the bottom of each movable bottom plate 5. Sliders 15 are movably arranged in the sliding grooves 14. Ear seats 16 are arranged at the bottoms of the sliders 15. The ear seats 16 are movably connected to the tops of telescopic cylinders 17. The bottoms of the telescopic cylinders 17 are installed at the bottom of the spraying chamber 1. By the telescopic movement of the telescopic cylinders 17, the movable bottom plates 5 are driven to rotate towards the middle direction along the support shaft 36. During this process, the powder ash accumulated on the movable bottom plates 5 falls into the collection grooves 12 under the action of suction and gravity.

[0025] Connecting plates 35 are respectively arranged on both sides of the speed reducer 9 and the bearing seat 11. A support shaft 36 is installed between the connecting plates 35, and the support shaft 36 is movably connected to one side of the movable bottom plate 5.

[0026] The rotating collecting shaft 4 has a hollow structure inside, and a plurality of notches 18 are formed along the long axis direction. The notches 18 are strip-shaped structures, so that blockage will not occur during the rotation process, and the rotation process is a uniform rotation, aiming to reduce dust.

[0027] The spraying assembly 2 includes a plurality of control boards 20, spray guns 21, supply pipes 22, a raw material bin 23 and a conical hopper 24. The control boards 20 are symmetrically installed on both sides of the spraying chamber 1 respectively, and a plurality of spray guns 21 are arranged inside each control board 20. The control boards 20 on each side are connected by a supply pipe 22. One end of the supply pipe 22 is communicated with the raw material bin 23. The raw material bin 23 is installed on the upper part of the spraying chamber, and a conical hopper 24 is further arranged on the upper part of the raw material bin 23.

[0028] Support columns 19 are further arranged at the four corners of the bottom of the spraying chamber 1, and anti-slip sleeves 30 are arranged at the bottoms of the support columns 19.

[0029] An observation window 31 is arranged on one side of the spraying chamber 1, and a transparent observation plate 32 is arranged inside the observation window 31. The internal operation condition can be observed at any time through the transparent observation plate 32.

[0030] Sealing doors 33 are arranged at both the inlet 7 and the outlet 8 of the spraying chamber 1, and handles 34 are further arranged on the sealing doors 33.

[0031] Working principle:

[0032] During the spraying operation, the moving track 3 pulls an object to pass through the spraying chamber 1 in turn, and the object is sprayed through the spray guns 21. The corresponding side walls on both sides of the spraying chamber are equivalent to iron plates, and the side walls are positively charged. In this way, the powder generated during the spraying process accumulates on the movable bottom plate 5 and the rotating collecting shaft 4 under the action of the electric field. The driving motor 10 is started to make the rotating collecting shaft 4 send the powder into the collecting groove 12 during the rotation process. Secondly, the powder on the movable bottom plate 5 makes the movable bottom plate 5 rotate towards the middle direction along the support shaft 36 by controlling the telescopic cylinder 17. During this process, the powder accumulated on the movable bottom plate 5 falls into the collecting groove 12 under the action of suction and gravity, and is recycled through the collecting box 6.

[0033] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
