[0002] As aircraft requirements for structural performance and low cost continue to increase, it has become an unstoppable trend for composite aviation components to gradually replace metal components. Among them, honeycomb core sandwich structure composite materials are gradually being used in civil or military aircraft due to their excellent properties such as light weight and high strength. For example, they are used in aircraft cabin floors, cargo floors, cockpit interiors, radar covers, etc.

[0003] The aramid paper honeycomb cores on the market are generally in the form of rectangular blocks. The common sizes of aramid paper honeycomb cores are 1.2m×2.4m, 1.3m×3.5m, 1.9m×2.9m, etc. The purchased honeycomb cores have many impurities and dust inside the gaps due to molding and processing. Although the honeycomb cores are protected to a certain extent during the molding and processing process, impurities and dust are still adsorbed on the surface of the honeycomb core gaps due to static electricity. These impurities and dust will seriously affect the performance and quality of the honeycomb core sandwich structure composite materials. Therefore, before making the honeycomb core sandwich structure composite materials, the honeycomb core needs to be dusted and removed.

[0023] like Figure 1 , Figure 2As shown, the conveying mechanism includes two conveyor belts 3 installed at intervals along the length direction of the dust removal bracket 1 and two sensors respectively arranged at the dust removal position and one side of the unloading mechanism, and also includes a conveying controller; wherein the sensor is electrically connected to the conveying controller, and the conveying controller is electrically connected to the conveyor belt 3.

[0024] In this embodiment, the two conveyor belts 3 are respectively coaxially passed through the transmission shafts at both ends of the conveyor belts, and one end of one of the transmission shafts is coaxially connected to a motor fixed to one side of the dust removal bracket 1 through a coupling; each transmission shaft is rotatably connected to the dust removal bracket 1 through a bearing.

[0025] In this embodiment, a raised inverted structure is provided on the outer surface of each conveyor belt 3 to increase the friction with the aramid paper honeycomb core, thereby improving the transmission efficiency; further, a baffle or a ratchet structure can be provided on the outer surface of each transmission shaft to prevent the conveyor belt 3 from slipping during the transmission process.

[0026] like Figure 1 , Figure 2 As shown, the moving mechanism includes a longitudinal transmission screw 401 installed on both sides of the dust removal bracket 1 along the length direction, the moving parts of the two longitudinal transmission screws 401 extend upward and are connected to the two ends of the transverse transmission screw 402 respectively, the moving part of the transverse transmission screw 402 is installed with a vertical motion module 403, and the bottom of the moving end of the vertical motion module 403 is connected to the dust removal head 404; the longitudinal transmission screw 401, the transverse transmission screw 402 and the vertical motion module 403 are respectively electrically connected to the controller.

[0027] In this embodiment, the base of the longitudinal transmission screw 401 is installed on both sides of the dust removal bracket 1 through a plurality of hexagon socket screws, the two ends of the base of the transverse transmission screw 402 are respectively installed on the top of the moving part of the longitudinal transmission screw 401 through a plurality of hexagon socket screws, and the base of the vertical moving module 403 is installed on the side of the moving part of the longitudinal transmission screw 401 through a plurality of hexagon socket screws; during the dust removal process, the dust removal head 404 is first moved to an initial position away from the top of the conveyor belt 3 through a moving mechanism, and after the aramid paper honeycomb core is fixed at the dust removal position, the controller controls the moving mechanism to move the dust removal head 404 to a working height according to the thickness of the aramid paper honeycomb core, so that the distance between the dust removal head 404 and the upper surface of the aramid paper honeycomb core meets the working distance of the dust removal head 404, and then the controller adjusts the working stroke of the longitudinal transmission screw 401 and the transverse transmission screw 402 according to the length and width of the aramid paper honeycomb core, and the moving mechanism drives the dust removal head 404 to perform reciprocating dust removal motion in the same horizontal plane, and compressed air blows off impurities and dust.

[0028] In this embodiment, the maximum effective stroke of the longitudinal transmission screw 401 is 4m, the maximum effective stroke of the transverse transmission screw 402 is 1.5m, the maximum effective stroke of the vertical motion module 403 is 300mm, the length of the dust removal head 404 along the length direction of the dust removal bracket 1 is 180mm, and the length of the dust removal head 404 along the length direction of the dust removal bracket 1 is 600mm.

[0029] like Figure 1 , Figure 2 As shown, the fixing mechanism includes a positioning baffle 5 arranged on the inner side of the dust removal bracket 1 along the length direction, a plurality of spaced-apart transverse clamping members 6 arranged opposite to the positioning baffle 5, and a plurality of spaced-apart longitudinal clamping members 7 arranged at the edge of the dust removal position and away from the running direction of the conveyor belt 3.

[0030] like Figure 3 As shown, the transverse clamping member 6 and the longitudinal clamping member 7 both include a clamping bottom plate 601, and the left and right sides of the clamping bottom plate 601 are both extended upwards with clamping side plates 602, and one end of the clamping bottom plate 601 and the clamping side plates 602 are fixedly connected to the dust removal bracket 1; the inner surfaces of the two clamping side plates 602 are respectively provided with a plurality of guide rails 603 at intervals, and one end of each guide rail 603 is tilted away from the dust removal bracket 1; and also include a vertically arranged baffle 604 for clamping the aramid paper honeycomb core, and the two ends of the baffle 604 The side is provided with multiple sliders 605 extending outward, and each slider 605 is correspondingly slidably inserted in each guide rail 603, and the side surface of the baffle 604 is also penetrated with a connecting hole 606; it also includes a cylinder 607 fixedly connected to the dust removal bracket 1, and the telescopic rod of the cylinder 607 extends into the dust removal bracket 1 and is connected to a connecting shaft 608, and two flange edges are arranged at intervals on the connecting shaft 608, and the connecting shaft 608 passes through the connecting hole 606, so that the two flange edges are respectively located on the inner and outer sides of the baffle 604.

[0031] In this embodiment, when the aramid paper honeycomb core needs to be fixed, the cylinder 607 pushes out the connecting shaft 608, and pushes the baffle 604 to move along the guide rail 603 under the action of the flange edge. During the movement, the guide rail 603 and the sliders 605 are mutually engaged, so that the baffle 604 remains in a vertical state; because the end of the guide rail 603 away from the dust removal bracket 1 is tilted, the baffle 604 moves obliquely upward along the guide rail 603, so that the upper end of the baffle 604 is higher than the clamping side plate 602, and the baffle 604 that is higher than the clamping side plate 602 can clamp the aramid paper honeycomb core; One end of the rail 603 is tilted, so the distance between the baffle 604 and the dust removal bracket 1 is adjustable, so it can be suitable for clamping aramid paper honeycomb cores of different sizes; when the aramid paper honeycomb core needs to be released from a fixed state, the telescopic rod of the cylinder 607 is retracted, and the baffle 604 can be pushed to move to one side of the dust removal bracket 1 under the action of the outer flange edge. After the baffle 604 moves obliquely downward along the guide rail 603, the top of the baffle 604 is flush with the top of the clamping side plate 602, and the movement away from the aramid paper honeycomb core is unprecedented, so it does not affect the subsequent continued transmission and unloading of the aramid paper honeycomb core.
