Description

Technical Field

[0001] The utility model relates to the technical field of honeycomb processing, in particular to a dust removal device for aramid paper honeycomb core materials. Background Art

[0002] Aramid honeycomb is a composite core material made from aramid paper through a series of processes, including gluing, lamination, hot pressing, impregnation, and slicing. It is primarily used in high-end sectors such as rail transit, aerospace, shipbuilding, and military applications. Sandwich-structured composite components made from aramid honeycomb core material combined with prepreg not only achieve lightweighting requirements but also offer numerous advantages, including corrosion resistance, noise reduction, and vibration damping. Consequently, aramid honeycomb has found widespread application in rail transit and aerospace interiors.

[0003] Existing dust removal methods mostly rely on manual vacuuming. Smaller-scale dust removal systems are also used, primarily consisting of air knives, ionizing air wands, negative pressure adsorption boxes, and a honeycomb core material conveyor belt. The conveyor belt transports the honeycomb core material sequentially to the ionizing air wands and air knives for dust removal, while the negative pressure adsorption box beneath the conveyor belt assists in dust collection. However, this method is ineffective for dust removal on the underside of the honeycomb core. The conveyor belt prevents dust from being collected from beneath the core material, and the wind force decreases sharply after the air knives penetrate the honeycomb panel, resulting in poor dust removal and the need for multiple dust removal attempts.

[0004] During the honeycomb core dust removal process, dust removal on the reverse side of the honeycomb core is also very important. On the one hand, it can avoid secondary dust removal and improve dust removal efficiency, and on the other hand, it can also improve product quality. Although the negative pressure adsorption box can remove most of the dust, the presence of the conveyor belt still seriously affects the dust removal effect, and the air knife is not effective in removing dust on the reverse side of the honeycomb core.

[0005] In summary, the current dust removal process of aramid honeycomb has the following disadvantages:

[0006] 1. The dust removal effect on the back of the composite core material made of aramid honeycomb is not good;

[0007] 2. The composite material core material made of aramid honeycomb needs to be dusted multiple times, and the efficiency is low. Utility Model Content

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] like Figures 1 to 4 As shown, an aramid paper honeycomb core material dust removal device provided by the present invention is used to remove dust from the aramid paper honeycomb core material, including a base 1, a vibration platform 2, a high-pressure air knife dust removal device 3, a high-pressure dust collector connection port 4 and a control system.

[0041] The base 1 is rectangular and its bottom structure is a funnel structure, which is placed on a plane through four legs. The bottom of the funnel structure is connected to the high-pressure dust collector through the high-pressure dust collector connection port 4 to collect dust blown out of the dust removal device.

[0042] The vibration platform 2 is mounted on the base 1 and is located above the funnel structure. An aramid paper honeycomb core material is placed on the vibration platform 2 to provide vibration force to the aramid paper honeycomb core material.

[0043] The vibration platform 2 includes a wire mesh platform 21, which is made of hollow wire mesh. The bottom of the wire mesh platform 21 is elastically mounted on the base 1 through a vibration reduction device; a V-shaped bracket 24 is provided at the bottom of the wire mesh platform 21, and the V-shaped bracket 24 is located directly above the funnel structure; a vibration motor 23 is provided within the angle of the V-shaped bracket 24, and the vibration motor 23 is connected to the V-shaped bracket 24 through a transmission plate.

[0044] The vibration reduction device includes heavy-load springs 22. Both sides of the wire mesh platform 21 are mounted on the base 1 through at least four groups of heavy-load springs 22. The heavy-load springs 22 are used to reduce the vibration of the vibration platform 2 on the base 1 during operation.

[0045] The high-pressure air knife dust removal device 3 is movably arranged above the vibration platform 2 and is used to remove static electricity and dust from the aramid paper honeycomb core material placed on the vibration platform 2.

[0046] The high-pressure air knife dust collector 3 comprises a steel frame 36, an ion wind bar 33, and a high-pressure air knife 34. An extension frame is mounted on the base 1, with a rack 13 connected between its two short sides, parallel to its long sides. A servo motor 32 is mounted on the steel frame 36. Its output shaft is connected to a gear 37, which drives the steel frame 36 on the rack 13. This shifts the high-pressure air knife dust collector 3 between the two short sides of the extension frame, thereby controlling its linear motion.

[0047] Two high-pressure air knives 34 and an ion wind rod 33 are provided below the steel frame 36 to remove dust and static electricity from the aramid paper honeycomb core material; the high-pressure air knives 34 and the ion wind rod 33 are set on the steel frame 36 through two groups of cylinders 31, and the two groups of cylinders 31 control the high-pressure air knives 34 and the ion wind rod 33 to adjust their height on the steel frame 36.

[0048] Furthermore, in this embodiment, auxiliary guide devices connect the two ends of the steel frame 36 on the two long sides of the extension frame, providing guidance for the high-pressure air knife dust collector 3 as it moves between the two short sides of the extension frame. The guide device includes guide rails 11 provided on each of the two long sides of the extension frame, and guide rail sliders 35 provided at each end of the steel frame 36. The steel frame 36 is slidably mounted on the two guide rails 11 via the guide rail sliders 35, which are used to support the load of the high-pressure air knife dust collector 3 and ensure that the high-pressure air knife dust collector 3 achieves guided linear motion.

[0049] Furthermore, in this embodiment, an acrylic cover 12 is provided on the extension frame. This acrylic cover 12 is a bottom-opening cover mounted on the base 1. This ensures that the dust removal environment is isolated from the outside world while also facilitating observation of the dust removal process and effectiveness of the aramid paper honeycomb core. One side of the acrylic cover 12 features an openable acrylic hinged door 14, through which the aramid paper honeycomb core is placed onto the wire mesh platform 21 for loading and unloading.

[0050] In this embodiment, the control system is used to control the air pressure of the high-pressure air knife 34 and the ion wind rod 33, the forward and reverse rotation and fixed-distance movement and speed of the servo motor 32, the adjustment of the cylinder 31, the air pressure control of the high-pressure dust collector, and the speed adjustment of the vibration motor 23.

[0051] The utility model also provides an application method of the aramid paper honeycomb core material dust removal device, comprising the following steps:

[0052] Step S1: Adjust the height of the ion wind rod 33 and the high-pressure air knife 34 of the steel frame 36 through the two sets of cylinders 31, and adjust the ion wind rod 33 and the high-pressure air knife 34 to the highest position;

[0053] Step S2: Open the acrylic panel hinge door 14, and the operator places the aramid paper honeycomb core material to be dusted centrally on the plane of the wire mesh platform 21;

[0054] Step S3: The heights of the ion wind rod 33 and the high-pressure air knife 34 are adjusted to the height of the aramid paper honeycomb core material by two sets of cylinders, and the overlapped position of the ion wind rod 33 and one side of the aramid paper honeycomb core material is defined as the starting point;

[0055] Step S4: Open the high-pressure dust collector;

[0056] Step S5: inputting the length of the inserted aramid paper honeycomb core material on the input interface of the control system;

[0057] Step S6: Close the acrylic panel hinge door 14, and the control system starts the ion wind rod 33, the high-pressure air knife 34, the servo motor 32, and the vibration motor 23;

[0058] The ion wind rod 33 and the high-pressure air knife 34 respectively remove static electricity and dust from the aramid paper honeycomb core material through the apertures thereon;

[0059] The servo motor 32 rotates on the rack 13 by driving the gear 37, thereby driving the steel frame 36 connected to the servo motor 32 to move on the wire mesh platform 21, so that the ion wind rod 33 and the high-pressure air knife 34 move from the starting point on one side of the aramid paper honeycomb core material in step S3 to the other side, thereby scanning the surface of the aramid paper honeycomb core material once;

[0060] The vibration motor 23 drives the transmission plate to transmit the vibration force to the wire mesh platform 21. Under the action of vibration, the wire mesh platform 21 vibrates the aramid paper honeycomb core material placed thereon, thereby shaking off the dust on the aramid paper honeycomb core material into the base 1 of the funnel structure below the wire mesh platform 21. The base 1 then collects the dust through the high-pressure dust collector connected to the high-pressure dust collector connection port 4 at its bottom.

[0061] Step S7: The servo motor 32 reciprocates once, so that the ion wind rod 33 and the high-pressure air knife 34 return from the other side of the aramid paper honeycomb core material in step S3 to the starting point on one side, and scans the surface of the aramid paper honeycomb core material back and forth again, and the dust removal is completed.

[0062] This utility model utilizes an ion wind bar to effectively remove static electricity from honeycomb core materials, preventing the static electricity from attracting dust while also removing some dust. The vibration platform effectively removes dust from the back side of the honeycomb core, and the back-and-forth motion of the vibration platform alone improves dust removal efficiency. The powerful air knife combined with the vibration platform completely removes dust.
