Description

Technical Field

[0001] The utility model relates to the technical field of electron beam curing, in particular to an electron beam device for curing high-temperature coatings. Background Art

[0002] A high-temperature coating is a special coating that can withstand high-temperature environments and can be used for a long time in high-temperature environments without failure or aging. Common organic high-temperature coatings include polyimide, acrylate, acrylate polyurethane, etc. When electron beams cure some epoxy resins, the glass transition temperature can reach 390°C, which has reached or even exceeded the performance of some polyimide resins. Therefore, it can be used to prepare high heat-resistant materials.

[0003] In order to avoid X-ray leakage into the environment during the electron beam curing process, electron beam curing equipment usually adopts a maze structure, allowing X-rays to refract multiple times before reaching the external environment. For a single relatively rigid plate-shaped material, since it cannot be bent, the transmission method of the maze structure is complex, occupying a large area, which hinders the popularization and application of electron beam radiation curing in the field of plates.

[0004] The existing publicly disclosed technical solution, with the publication number CN218948210U, discloses a plate electron beam curing system. By setting more than three shielding doors in the ray shielding device, when the plate is transported, the opening states of each door are controlled by a power mechanism, so that at least one door is in a completely closed state in the shielding channel constructed by the ray shielding device, realizing ray shielding in the channel and directly adopting linear transmission to reduce the floor area.

[0005] This plate electron beam curing system transports the plate through a conveyor belt. The plate is directly placed on the conveyor belt, and the bottom of the plate is in contact with the conveyor belt. For plates that need to be cured on both the front and back sides, only one side can be cured. After the front side is cured, the plate is turned over and then the back side is cured, resulting in low work efficiency. Summary of the Invention

[0006] The purpose of the utility model is to provide an electron beam device for curing high-temperature coatings, which can vacate the position at the bottom of the plate that needs to be cured without damaging the coating at the bottom of the plate, so as to solve the problems raised in the above background art.

[0008] The plate conveying mechanism includes a transmission chamber slidably installed on the top of the electron beam curing machine tool. Inside the transmission chamber is provided a lower pressing plate, and below the lower pressing plate is provided a lower pressing spring. Above the lower pressing plate is slidably installed a placement adjusting plate, and a limiting groove is opened at the connection between the placement adjusting plate and the transmission chamber. On one side of the lower pressing plate is installed a connecting rod, and the connecting rod penetrates through one end face of the transmission chamber. A guiding sliding groove is opened at the connection between the placement adjusting plate and the lower pressing plate.

[0009] Preferably, the placement adjusting plate is located on the top of the transmission chamber, and the placement adjusting plate is elastically connected to the transmission chamber through the lower pressing plate and the lower pressing spring.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] The present invention provides a technical solution:

[0027] Please refer to Figures 1 to 3 , a high-temperature coating curing electron beam device, including an electron beam curing machine tool 1, a curing chamber 2 for curing the plate coating is installed on the top of the electron beam curing machine tool 1, and a curing component main body 6 is slidably installed inside the curing chamber 2. Feeding ports and discharging ports are respectively opened on the left and right sides of the curing chamber 2. A plate conveying mechanism 4 is arranged on one side of the feeding port, a conveyor belt 3 is arranged on one side of the discharging port, and a curing component adjusting mechanism 5 is installed on the top of the curing component main body 6;

[0028] The plate conveying mechanism 4 includes a transmission chamber 401 slidably installed on the top of the electron beam curing machine tool 1. A lower pressing plate 405 is arranged inside the transmission chamber 401. A lower pressing spring 407 is arranged below the lower pressing plate 405. A placement adjusting plate 403 is slidably installed above the lower pressing plate 405. A limiting groove 404 is opened at the connection between the placement adjusting plate 403 and the transmission chamber 401. A connecting rod 408 is installed on one side of the lower pressing plate 405, and the connecting rod 408 penetrates through one end face of the transmission chamber 401. A guiding sliding groove 406 is opened at the connection between the placement adjusting plate 403 and the lower pressing plate 405. The placement adjusting plate 403 is located on the top of the transmission chamber 401, and the placement adjusting plate 403 is elastically connected to the transmission chamber 401 through the lower pressing plate 405 and the lower pressing spring 407. An electric slide rail 402 is installed at the connection between the transmission chamber 401 and the electron beam curing machine tool 1. A plate main body 8 is arranged above the transmission chamber 401. The length of the transmission chamber 401 is less than the length of the plate main body 8. A vertical slot for the up and down movement of the connecting rod 408 is opened at the connection between the connecting rod 408 and the transmission chamber 401.

[0029] By adopting the above technical solution, for the plate body 8 that needs to be cured on both the front and back sides, it can be directly placed on the placement adjustment plate 403. At this time, the placement adjustment plate 403 can drive the lower pressing plate 405 to move downward and compress the lower pressing spring 407. Under the action of the electric slide rail 402, the plate gradually enters the curing chamber 2, and the front and back sides of the plate body 8 are cured by the curing component main body 6. The penetration depth of the electron beam can be increased by adjusting the electron beam energy of the curing component main body 6, so as to realize the curing of both the front and back sides of the plate body 8. After the plate body 8 is cured, it continues to move to the left. Since the length of the plate body 8 is relatively long, as the transmission chamber 401 moves, the plate body 8 reaches the conveyor belt 3 and is conveyed out along with the conveyor belt 3.

[0030] Specifically, as Figure 1 and Figure 4 shown, the curing component adjusting mechanism 5 includes a transmission rack 502 fixed to one side of the connecting rod 408, and a transmission gear 501 is arranged above the transmission rack 502. A winding shaft 503 is fixedly installed in the middle of the transmission gear 501, and a winding rope 504 is wound around the outside of the winding shaft 503. A first fixed pulley 505 and a second fixed pulley 506 are sequentially installed on the surface of the winding rope 504, and a fixing member 507 is arranged at the end of the winding rope 504. The fixing member 507 is fixedly welded to the top of the curing component main body 6. A guiding slide rod 7 is arranged on one side of the curing component main body 6, and a guiding groove is arranged at the connection between the guiding slide rod 7 and the curing chamber 2. The guiding groove is opened on the inner wall of the curing chamber 2.

[0031] By adopting the above technical solution, when it is necessary to adjust the height of the curing component main body 6, the plate body 8 can be placed on the top of the transmission chamber 401. At this time, the transmission rack 502 on the connecting rod 408 and the transmission gear 501 are in a meshing state. As the transmission chamber 401 continues to feed, the transmission gear 501 can be driven to rotate by the transmission rack 502, and the winding shaft 503 on the transmission gear 501 rotates, winding the winding rope 504 inward, so as to pull the curing component main body 6 upward through the winding rope 504 to adjust the height of the curing component main body 6. When it is not necessary to adjust the height of the curing component main body 6, the plate body 8 can be directly placed on the placement adjustment plate 403. The placement adjustment plate 403 can drive the lower pressing plate 405 to move downward and compress the lower pressing spring 407, and the transmission rack 502 on the connecting rod 408 and the transmission gear 501 are in a separated state, and the feeding of the transmission chamber 401 will not drive the transmission gear 501 to rotate.

[0032] Working principle: The plate body 8 that needs to be cured on both sides is placed on the placement adjustment plate 403. The placement adjustment plate 403 drives the lower pressing plate 405 to move downward, and presses the lower pressing spring 407. The transmission rack 502 on the connecting rod 408 is separated from the transmission gear 501. After the electric slide rail 402 is powered on, the plate gradually enters the curing chamber 2. The electron beam energy of the curing component body 6 is increased to increase the penetration depth of the electron beam, so as to realize the double-sided curing of the front and back sides of the plate body 8. After the plate body 8 is cured, it continues to move to the left. Since the length of the plate body 8 is relatively long, as the transmission chamber 401 moves, the plate body 8 reaches the conveyor belt 3 and is conveyed out along with the conveyor belt 3.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
