[0002] A new type of material made by combining resin and reinforcing fiber through a composite process has been increasingly used in fuselages, wings and other structural parts of aircraft in recent years. Since aluminum alloys and composite materials have their own advantages and limitations in aircraft, they need to be combined during the design and manufacturing process. However, the combined connection technology of aluminum alloys and composite materials is complex and has many problems, so the surface pretreatment of the connecting parts plays a vital role. Before the adhesive is bonded to aluminum alloys and composite materials, it is necessary to ensure that the surface is clean and clean so that the adhesive can effectively adhere and form a strong bond. Sandblasting is an important pretreatment step to improve the bonding between the composite surface and the adhesive. However, ordinary sandblasting machines are easily affected by dust contamination when processing composite panels, resulting in poor uniformity of the sandblasted surface and easy damage to the substrate surface.

[0018] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] like Figs. 1-3 As shown, a surface pretreatment device for resin and reinforced fiber composite materials includes: a casing 1, a chain drive roller group 2, a bracket 3, a sandblasting device 4, a circulating material box 5, and a dust suppression device 6; the casing 1 is mounted above the bracket 3, the chain drive roller group 2 is also mounted on the bracket and passes through the bottom of the side wall of the casing 1, the distance between adjacent drive rollers of the chain drive roller group 2 is greater than the width of a single drive roller, a motor 20 is fixedly mounted at the bottom of the bracket 3, the chain drive roller group 2 and the motor 20 are connected by chain drive, the circulating material box 5 is fixedly mounted directly below the casing 1, and an electric valve 50 is provided on the side of the circulating material box 5;

[0021] The sandblasting device 4 includes a sandblasting head 40, a feed pipe 41, and an air pipe 42. The sandblasting head 40 is fixedly mounted on the top wall of the housing 1. The inlet end of the feed pipe 41 is fixedly connected to the electric valve 50. The outlet end of the feed pipe 41 passes through the housing 1 and is connected to the sandblasting head 40. The sandblasting head 40 is connected to the air pump via the air pipe 42.

[0022] The dust reduction device 6 includes a fan 60, a dust reduction box 61, a water tank 62, a water pump 63, and a water pipe 64. A reserved hole is opened on the side wall of the casing 1, and the fan 60 is fixedly connected to the inside of the reserved hole. The dust reduction box 61 is fixedly connected to one side of the casing 1. The dust reduction box 61 is an L-shaped structure. A water spray head 65 is fixedly installed above the side of the dust reduction box 61 away from the casing 1. A sewage box 66 is provided below the water spray head 65. One end of the water pipe 64 passes through the top of the dust reduction box 61 and is connected to the water spray head 65. The other end of the water pipe 64 is connected to the water tank 62 through the water pump 63.

[0023] Specifically, the composite material plate to be processed is placed on the chain drive roller group 2 in the housing 1. After the motor 4 is turned on, the chain drive roller group 2 drives the composite material plate to move horizontally toward the rear side of the device. Sand is stored in the circulating material box 5. The air pump and the electric valve 50 are turned on to sandblast the composite material plate through the sandblasting nozzle 40. The sprayed sand falls into the circulating material box 5 through the gap between the adjacent drive rollers of the chain drive roller group 2 for continued use. During the sandblasting process, the air flow rate in the housing 1 is increased by turning on the fan 60, and the dust in the air is blown into the dust reduction box 61. The water pump 63 is turned on to pump water from the water tank 62. The water is transported to the water nozzle 65 through the water pipe 64 to spray out the dust entering the dust reduction box 61, so that the dust no longer floats in the air. The sewage after dust reduction falls into the sewage box 66 for collection.

[0024] The device also includes a connecting block 70, a spring 71, and a brush 72. The connecting block 70 is fixedly mounted on the top surface of the housing 1. The bottom of the connecting block 70 is fixedly connected to the spring 71. The bottom of the spring 71 is connected to the brush 72. The brush 72 is located in front of the sandblasting device 4. The brush 72 cleans away dust already present on the composite material board, and the spring 71 allows the device to adapt to composite material boards of varying thicknesses.

[0025] A filter 51 is fixedly mounted within the circulating material box 5. The filter 51 is tilted, with its lower end positioned below the electric valve 50. A collection port 52 is provided at the bottom of the circulating material box 5. Sandblasting with 60-mesh quartz particles maximizes the bond peel strength of composite materials. Therefore, a filter 51 with a pore size of less than 125 μm is used to filter dust that enters the bottom of the circulating material box 5 and is discharged through the collection port 52. Sand is then discharged from the electric valve 50 along the tilt of the filter 51, allowing the sandblasting process to continue.

[0026] A hatch 10 is provided on the front side of the casing 1, and the upper end of the hatch 10 is hinged to the casing 1. Materials can be placed and sand can be added by opening the hatch 10.

[0027] An observation window 11 is provided on the hatch 10. The observation window 11 is provided to facilitate observation of the treatment situation.

[0028] The dust suppression box 61 has a reserved notch on the front side, and the front panel of the sewage box 66 fits into the reserved notch. A pulley 67 is installed at the bottom of the sewage box 66, and a handle 68 is installed on the front panel of the sewage box 66. When collecting sewage, the handle 68 can be pulled out to pull the sewage box 66 out, and the sewage box 66 can slide on the pulley 67.

[0029] The working principle and usage process of the present invention are as follows: the hatch 10 is opened, the composite material plate to be processed is placed on the chain drive roller assembly 2, and the hatch 10 is closed. After the motor 4 is turned on, the chain drive roller assembly 2 drives the composite material plate to move horizontally toward the rear side of the device. The air pump and electric valve 50 are turned on to sandblast the composite material plate through the sandblasting nozzle 40. The sprayed sand falls through the gaps between adjacent drive rollers of the chain drive roller assembly 2 into the recycling material box 5 for further use. During the sandblasting process, the fan 60 is turned on to increase the air flow rate within the housing 1, blowing the dust in the air into the dust reduction box 61. The water pump 63 is turned on to pump water from the water tank 62. The water is transported to the water nozzle 65 through the water pipe 64 and sprayed to reduce the dust entering the dust reduction box 61, so that the dust no longer floats in the air. The dust-removed wastewater falls into the wastewater box 66 for collection. After processing, the filtered dust is recovered from the collection port 52. The wastewater box 66 is pulled out by pulling the handle 68 to recover the wastewater.

[0030] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or they are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
