[0002] In order to protect the surface of metals, plates, etc., different types of coatings are usually applied to the surface of the substrate. In order to make the coating adhere tightly to the substrate, the coating will be cured. Common coating curing methods include thermal curing, light curing and oxidation curing.

[0003] Thermosetting paint uses high-temperature heating to cause a chemical reaction in the curing agent in the paint, thereby forming a hard and wear-resistant film. It has the characteristics of fast curing speed and strong adhesion. However, due to the high curing temperature of thermal curing, it may cause deformation of the product; light curing uses ultraviolet or visible light to cure the paint. It has certain limitations when used and can only cure where the light is exposed; oxidation curing uses oxygen in the air to cure the paint. The paint cures slowly and requires a longer curing time.

[0004] In order to solve the shortcomings of the above-mentioned common curing methods, the existing public technical solution, with announcement number CN218554671U, discloses an electron beam curing device, which can perform electron beam curing on the paint surface after painting through the electron beam curing mechanism. By using the electron beam as the irradiation energy, the electron beam and the active liquid chemical formula undergo radiation chemical reaction, which can be quickly dried and cured at room temperature.

[0005] During the electron beam curing process, the accelerator generates X-rays while generating electrons, which can have adverse effects on the human body and the surrounding environment. Therefore, shielding facilities are installed on the curing equipment. It is particularly important to ensure that the substrate passes through the shielding door smoothly without damaging the paint surface. Summary of the invention

DETAILED DESCRIPTION

[0027] 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.

[0028] The utility model provides a technical solution:

[0029] See also Figures 1 to 3A multifunctional electron beam curing device comprises a production line machine tool 1, a curing chamber 2 for electron beam curing of a substrate is installed on the top of the production line machine tool 1, and a curing assembly is arranged inside the curing chamber 2, a feed port and a discharge port are arranged on the left and right sides of the curing chamber 2, and a shielding door adjustment assembly 4 for adjusting the height of the shielding door is installed on one side of the feed port and the discharge port, and the curing assembly is an existing electron beam curing mechanism;

[0030] The shielding door adjustment assembly 4 comprises a shielding door body 406 respectively installed inside the feed port and the discharge port, a connector 405 is fixedly welded on the top of the shielding door body 406, and a rope 401 is connected inside the connector 405, and a second fixed pulley 403, a third pulley 404 and a first fixed pulley 402 are sequentially passed through the surface of the rope 401;

[0031] A conveying assembly 3 for conveying the substrate is fixed to one side of the first fixed pulley 402. The conveying assembly 3 includes a transmission rod 307 installed on one side of the first fixed pulley 402, and a wedge 303 is fixedly installed at the end of the transmission rod 307. A pressing rod 304 is arranged below the wedge 303, and a guide rod 306 is sleeved on the outside of the pressing rod 304.

[0032] By adopting the above technical solution, when the plate is close to the wedge piece 303, it continues to move in the direction of the wedge piece 303, and can press the wedge piece 303 downward along the slope of the wedge piece 303, thereby driving the first fixed pulley 402 to move downward through the transmission rod 307 on the wedge piece 303, and the two ends of the rope 401 are respectively fixed on the first fixed pulley 402 and the connecting piece 405. When the first fixed pulley 402 moves downward, one end of the rope 401 moves downward, so that the rope 401 slides on the second fixed pulley 403 and the third pulley 404, and pulls the connecting piece 405 to move upward, thereby driving the shielding door body 406 to move upward into the interior of the curing bin 2. At this time, the plate can smoothly enter the curing bin 2.

[0033] Specifically, Figure 3 and Figure 4As shown, a return spring 305 is provided at the connection between the guide rod 306 and the lower pressure rod 304, and the two ends of the return spring 305 are respectively connected to the guide rod 306 and the lower pressure rod 304, a magnetic suction plate 308 is fixedly installed below the guide rod 306, the wedge 303 is made of metal, and the wedge 303 is magnetically attracted to the magnetic suction plate 308, the side of the wedge 303 close to the curing bin 2 is higher than the side of the wedge 303 away from the curing bin 2, and the left and right sides of the wedge 303 are provided with a transmission belt 302, and the wedge 303 is far away from the curing bin 2. The side away from the curing bin 2 is located in the same horizontal plane as the top end surface of the transmission belt 302, a transmission wheel is installed inside the transmission belt 302, and a transmission shaft 301 is installed between the transmission wheels, one end of the transmission shaft 301 is fixedly connected to the power output end of the servo motor, the transmission rod 307 is an L-shaped structure, and the two ends of the transmission rod 307 are respectively connected to the wedge 303 and the first fixed pulley 402, one end of the rope 401 passes through the interior of the curing bin 2, and the rope 401 passes through the gap between the transmission belt 302 and the production line machine tool 1.

[0034] By adopting the above technical solution, after the servo motor is started, the power output end of the servo motor can drive the transmission shaft 301 to rotate, thereby driving the transmission belt 302 to rotate, and the plate placed on the transmission belt 302 is moved in the direction close to the wedge 303 until it reaches the position of the wedge 303. When the wedge 303 moves downward, it can also drive the lower pressure rod 304 to move downward, squeezing the return spring 305 and the wedge 303 moves to the side close to the magnetic attraction plate 308. The magnetic attraction plate 308 is in the state of electromagnet power supply, and a magnetic field is generated between it and the wedge 303. The magnetic attraction force between the magnetic plate 308 and the wedge 303 is greater than the elastic force of the reset spring 305, thereby locking the height of the wedge 303. When the plate completely enters the curing chamber 2, the end of the plate is away from the wedge 303, and the magnetic plate 308 is powered off. At this time, the magnetic attraction force between the magnetic plate 308 and the wedge 303 disappears, and the wedge 303 is pushed upward by the elastic force of the reset spring 305. Under the action of gravity, the shielding door body 406 moves downward and closes again to prevent excessive leakage of X-rays during the electron beam curing process.

[0035] Working principle: the plate is placed on the transmission belt 302, and the servo motor is started. The power output end of the servo motor drives the transmission shaft 301 to rotate, and the plate moves toward the direction close to the wedge 303. When the plate reaches the position of the wedge 303, it is continuously fed along the slope of the wedge 303, thereby pressing the wedge 303 downward, and the transmission rod 307 on the wedge 303 drives the first fixed pulley 402 to move downward. Since the two ends of the rope 401 are respectively fixed on the first fixed pulley 402 and the connecting piece 405, the rope 401 slides on the second fixed pulley 403 and the third pulley 404, and pulls the connecting piece 405 to move upward, thereby driving the shielding door body 406 to move upward into the interior of the curing bin 2. At this time, the plate can smoothly enter the curing bin 2.

[0036] 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.
