[0002] The EB curing technology for boards refers to the process of using an electron beam as a radiation source to induce a specially configured 100% solid material to quickly transform into a solid on the board surface. The EB curing technology can reduce the emission of volatile organic compounds and contribute to environmental protection.

[0003] Since the irradiation area of ​​the electron beam contains X-rays, up and down slopes are set on the EB curing production line to reduce the amount of radiation leaking from the inlet and outlet of the production line, but this method will result in low production efficiency;

[0004] The existing public technical solution, with the announcement number CN210392527U, discloses an electron beam curing shielding device for continuous feeding of plates. Multiple shielding doors are set in the feeding area and the discharging area to seal the gas and play a shielding role to prevent radiation leakage. The plates are pushed by the conveying rollers so that the plates are continuously conveyed without stopping, which speeds up the movement of the plates and improves the production efficiency of the production line.

[0005] In order to avoid the presence of dust, oil, moisture or other impurities on the surface of the plate, which may hinder the effective contact between the electron beam and the coating or adhesive, the plate will be cleaned before electron beam curing. However, it is still exposed to the air during transportation on the production line. During this process, a small amount of floating dust will inevitably fall on the plate. If this dust enters the curing area with the plate, it may affect the adhesion and durability of the coating and reduce the quality of the product. Summary of the invention

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides a technical solution:

[0028] See also Figures 1 to 4 , an electron beam curing shielding device for continuous feeding of a plate, comprising a frame 1, a conveyor belt 2 is arranged inside the frame 1, and a curing area 3 is arranged above the conveyor belt 2, a feed port and a discharge port are respectively opened on the left and right sides of the curing area 3, a height adjustment mechanism 4 is arranged on one side of the feed port, and a cleaning mechanism 5 is arranged above the feed port;

[0029] The cleaning mechanism 5 includes a support frame 503 arranged on one side of the curing area 3, and a servo motor 502 is fixedly installed at the front end of the support frame 503 by bolts, and the power output end of the servo motor 502 is connected to a winding roller 501; the height adjustment mechanism 4 includes a cleaning bracket 405 fixed on the top of the frame 1, and a cleaning roller 401 is arranged inside the cleaning bracket 405, and a cleaning tape 504 is arranged between the cleaning roller 401 and the winding roller 501, and the two ends of the cleaning tape 504 are respectively wound around the outside of the cleaning roller 401 and the winding roller 501, and a shielding door 6 is installed inside the feed port and the discharge port, and a connecting shaft 7 is installed at the connection between the shielding door 6 and the curing area 3.

[0030] By adopting the above technical solution, the servo motor 502 is started, and the power output end of the servo motor 502 can drive the winding roller 501 to rotate, so that the cleaning tape 504 is wound by the winding roller 501, and the cleaning tape 504 is pulled to be wound around the winding roller 501. At the same time, the winding action of the cleaning tape 504 drives the cleaning roller 401 to rotate. When the plate passes through the conveyor belt 2 and reaches the bottom of the cleaning roller 401, the front end first contacts with the cleaning tape 504. In order to prevent the plate from adhering to the cleaning tape 504 and being unable to move smoothly, the friction between the conveyor belt 2 and the plate is greater than the friction between the cleaning tape 504 and the plate. The cleaning tape 504 is adhesively bonded, and as the cleaning tape 504 is wound backward, the plate is moved backward. In order to enable the cleaning tape 504 to move the plate toward the direction of the feed port when it is wound, the cleaning tape 504 is wound out from the rear of the cleaning roller 401 during installation, bypasses the top of the winding roller 501 and is wound around the outside of the winding roller 501. At the same time, the cleaning tape 504 is separated from the plate under the continuous action of the conveyor belt 2, thereby completing the cleaning of the plate. The shielding door 6 can be rotated and opened under the action of the connecting shaft 7, and the cleaned plate enters the curing area 3 through the opened shielding door 6 for electron beam curing treatment.

[0031] Specifically, Figure 2 As shown, the height adjustment mechanism 4 also includes a lifting slider 406 arranged at the left and right ends of the cleaning roller 401, and a transmission bearing 407 is arranged at the connection between the lifting slider 406 and the cleaning roller 401, a lifting slide groove 402 is opened at the connection between the lifting slider 406 and the cleaning bracket 405, and the top of the lifting slider 406 is connected with a lifting screw 403 through a bearing, a nut is installed at the connection between the lifting screw 403 and the cleaning bracket 405, and a handle 404 is fixedly welded on the top of the lifting screw 403, the handle 404 is lifted and lowered on the cleaning bracket 405 through the lifting screw 403, and the lifting screw 403 is threadedly connected to the cleaning bracket 405 through a nut.

[0032] By adopting the above technical solution, when the height of the cleaning roller 401 needs to be adjusted, the handle 404 can be turned. When the handle 404 is turned, the lifting screw 403 is driven to rotate, and the lifting screw 403 is rotated in the cleaning bracket 405 through the nut. At the same time, the lifting screw 403 rotates in the bearing. As the lifting screw 403 is continuously fed, the lifting slider 406 can be driven to move up and down in the lifting slide groove 402, so that the cleaning roller 401 moves up and down, and the height between the cleaning roller 401 and the conveyor belt 2 can be adjusted. At this time, the height between the cleaning roller 401 and the conveyor belt 2 can be adapted to the thickness of the plate, and the cleaning tape 504 can be in contact with the plate. The plate is cleaned by the rotating cleaning tape 504, and dust can adhere to the cleaning tape 504. The used cleaning tape 504 is wound up from the rear through the winding roller 501.

[0033] Working principle: according to the thickness of the plate, the handle 404 is turned to drive the lifting screw 403 to rotate, thereby pushing the lifting slider 406 to move downward, and the height between the cleaning roller 401 and the conveyor belt 2 is adjusted so that the cleaning tape 504 can contact the plate. When the plate passes through the conveyor belt 2 and reaches the bottom of the cleaning roller 401, the front end first contacts the cleaning tape 504, and the power output end of the servo motor 502 drives the winding roller 501 to rotate. The winding roller 501 can pull the plate backward while winding the cleaning tape 504, and the cleaning tape 504 is separated from the plate under the continuous action of the conveyor belt 2, thereby completing the cleaning of the plate. The cleaned plate enters the curing area 3 through the shielding door 6 for electron beam curing treatment.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
