Description

Technical Field

[0001] The utility model relates to the technical field of coating devices, and more specifically, to a coating device for preparing radar-absorbing honeycomb materials. Background Technique

[0002] With the rapid development of modern technology, radar detection technology is increasingly widely used in military, aviation, aerospace and civilian fields, and the demand for target stealth technology is becoming more and more urgent. Radar stealth technology mainly realizes the stealth effect of the target by reducing the radar echo intensity, that is, reducing the radar cross section. Reducing the radar cross section is mainly achieved through radar-absorbing materials.

[0003] Radar-absorbing materials are a kind of functional materials that can attenuate and absorb the electromagnetic wave energy incident on their surfaces. When coating radar-absorbing honeycomb materials, the preparation process of traditional radar-absorbing honeycomb materials mostly relies on manual coating. The production efficiency of manual coating is low and the production cost is high. In order to achieve the effect of efficient coating, at present, a mechanized coating device is usually used to replace manual coating operation. This type of coating device generally uses a pipeline to transport the coating and cooperates with the movement of a squeegee to achieve the scraping and leveling operation and obtain a better coating effect.

[0004] However, there is no corresponding component for recovering excess coating on this type of coating device. Since the amount of coating sprayed on the material surface is generally slightly more than the specified amount to ensure that each part can be evenly coated sufficiently, at this time, a certain amount of excess coating will be generated after each coating operation. The non-recovery of this part of the excess coating will cause a certain amount of resources to be wasted, and the remaining excess coating on the material also affects the uniformity of its coating, bringing inconvenience to users. In view of this, we have proposed a coating device for preparing radar-absorbing honeycomb materials. Content of the Utility Model

[0030] Specifically, a secondary box 15 communicating with the inside of the raw material constant temperature storage box 1 is provided at the rear of the raw material constant temperature storage box 1. A slide rail 17 is fixedly installed on the rear side surface of the U-shaped frame 13. A pouring component 2 is arranged on the slide rail 17. The pouring component 2 includes a servo motor 20 fixedly installed at the end of the slide rail 17. A lead screw 21 is fixedly installed at the end of the output shaft of the servo motor 20. A slider 22 threadedly connected to the lead screw 21 and slidably connected to the slide rail 17 is provided on the lead screw 21. A top plate 23 is fixedly installed on the top of the slider 22. A transfer pump 24 is fixedly installed on the top plate 23. A suction pipe 25 inserted into the secondary box 15 is fixedly installed at the liquid inlet end of the transfer pump 24. A discharge pipe 26 is fixedly installed at the liquid outlet end of the transfer pump 24. A coating plate 27 is fixedly installed on the top plate 23. Both the coating plate 27 and the discharge pipe 26 are located above the support plate 10, so as to realize the transfer of paint by the transfer pump 24 and the leveling of the paint by the coating plate 27, thereby realizing the pouring operation.

[0031] In this embodiment, a plurality of nozzles 261 arranged linearly and at equal intervals are fixedly installed at the bottom of the discharge pipe 26. The coating plate 27 is located behind the discharge pipe 26, and the nozzles 261 are used for the spraying operation of the paint.

[0032] Specifically, the bottom end of the suction tube 25 extends into the liquid surface in the auxiliary tank 15, and a plurality of suction holes 251 connected to the outside world are provided on the bottom tube body of the suction tube 25, so that the paint can enter more smoothly along the end pipe mouth and the suction hole 251 of the suction tube 25; a rectangular hole 16 arranged along the length direction of the auxiliary tank 15 is provided on the top plate of the auxiliary tank 15, and the suction tube 25 is inserted into the rectangular hole 16 and is slidably connected with the rectangular hole 16, so that the suction tube 25 can move synchronously and perform suction operations.

At the same time, the coating plate 27 can also be replaced to realize the replacement of coating plates 27 of different heights for scraping operation.

[0034] In addition, a limiting plate 12 is fixedly installed at the center position of the front side plate of the support plate 10. The height of the limiting plate 12 is between 1.5 cm and 2.3 cm. The setting of the limiting plate 12 can achieve the effect of pressing the radar absorbing honeycomb material against the limiting plate 12 for limiting and then coating.

[0035] It is worth noting that a feed pipe 14 is fixedly installed on the top box of the raw material constant temperature storage box 1, and the feed pipe 14 is flange-connected to the external pipeline.

Connect the transfer pump 24 to an external power source and make it work. When the transfer pump 24 works, the coating material in the secondary tank 15 is pumped in from the suction pipe 25 and sprayed out from the nozzle 261 onto the radar absorbing honeycomb material. Then, connect the servo motor 20 to an external power source and make it work. When the servo motor 20 works, the output shaft on it rotates to drive the lead screw 21 to rotate. The rotation of the lead screw 21 drives the slider 22 connected to it by threads to move.

The movement of the coating plate 27 realizes moving along the surface of the radar absorbing honeycomb material to perform the operation of leveling the coating material. As the coating plate 27 moves towards the side of the residual material hole 11, the excess coating material on the surface of the radar absorbing honeycomb material is pushed to the residual material hole 11 and flows back to the raw material constant temperature storage tank 1. After the coating is completed, the servo motor 20 continues to work, driving the top plate 23 to move towards the side away from the residual material hole 11 and return to the initial position, and then take out the material after dip coating.
