Description

Technical Field

[0001] The utility model relates to the technical field of curing, in particular to an electron beam composite curing device. Background Art

[0002] The electron beam composite curing device is a device used to implement electron beam curing technology. Electron beam curing technology mainly uses the high-energy electron beam generated by the electron accelerator to interact with the material, triggering resin polymerization or cross-linking, thereby accelerating the cross-linking reaction inside the material, so that the coating or material is quickly cured and forms a hard surface. The mechanism of electron beam curing mainly includes cross-linking reaction, thermal effect and radiation effect. The cross-linking reaction refers to the process in which the electron beam interacts with the functional groups in the material to form a cross-linking chain, which can increase the hardness and wear resistance of the material.

[0003] The existing curing method dries the paint layer by hot air generated by heating. However, since the drying air contains paint components with low melting points, direct emission will cause environmental pollution problems.

[0004] The existing patent (publication number: CN218554671U) discloses an electron beam curing device, which includes a carrying frame, an electron beam curing mechanism and a cross plate. The electron beam curing mechanism is composed of a crawler conveyor, a concave frame, an electron beam emitter and a nozzle frame. Through the conveyance of the crawler conveyor, the painted product is transported to the concave frame, and the electron beam hits the paint surface, so that the electron beam and the active liquid paint surface undergo a radiation chemical reaction to quickly dry and cure.

[0005] In response to the above problems, the solution given in the existing patent is to use electron beam curing to reduce environmental pollution. However, the workpiece is transported by a conveyor belt without any limiting structure during transportation, which causes the workpiece to easily shift during transportation. The shifted workpiece cannot be irradiated by the electron beam normally, and the curing effect cannot be guaranteed. Summary of the invention

Two installation cavities are opened at the lower end inside the curing part. Springs are installed inside the two installation cavities. The ends of the springs are abutted and connected with movable plates. Fixed plates are fixed at the lower ends of both sides of the movable plates.

DETAILED DESCRIPTION

[0025] 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] See also Figures 1 to 4 An electron beam composite curing device comprises a device base 1, a protective shell 4 is fixed on the upper surface of the device base 1, an adjusting electric cylinder 5 is fixed to the upper end of the protective shell 4 by bolts, a curing mechanism for curing a workpiece is fixed to the telescopic end of the adjusting electric cylinder 5 penetrating the protective shell 4, and a gas transmission mechanism for storing nitrogen is provided on the upper surface of the protective shell 4 and close to the adjusting electric cylinder 5;

[0028] The curing mechanism includes a curing part 6, which is fixed to the telescopic end of the adjusting electric cylinder 5. Two installation cavities 61 are provided at the lower end of the interior of the curing part 6. Springs 62 are installed inside the two installation cavities 61. The ends of the springs 62 are abutted and connected with movable plates 63. Fixed plates 64 are fixed to the lower ends of both sides of the movable plates 63. Fixed bearings 65 are inlaid inside the two fixed plates 64. Guide rollers 66 are fixed inside the fixed bearings 65. An electron beam generator 67 is installed inside the curing part 6. A plurality of ventilation holes 68 are provided at the upper end of the inner wall of the curing part 6. A conveying motor 2 is fixed to the right side of the device base 1 by bolts, and a conveyor belt 3 is installed inside the device base 1.

[0029] By adopting the above technical solution, before using the electron beam composite curing device, the device base 1 is first placed in a suitable position, and then the workpiece to be cured is placed on the conveyor belt 3, and the conveying motor 2 on the device base 1 drives the transmission roller on the inner wall of the conveyor belt 3 to rotate, thereby driving the conveyor belt 3 to run and convey the workpiece. When the workpiece is conveyed into the protective shell 4, the set adjustment electric cylinder 5 drives the curing part 6 to move vertically, so as to adjust the height of the curing part 6, which is convenient for curing workpieces of different thicknesses, and when the curing part 6 moves, it drives the guide roller 66 to move vertically. At this time, the two guide rollers 66 are respectively and The two sides of the workpiece are in contact, thereby limiting the workpiece, and the spring 62 arranged in the installation cavity 61 can drive the movable plate 63 to move vertically, ensuring that the two guide rollers 66 can normally contact the workpiece. When the workpiece is being conveyed, friction is generated between the movement of the workpiece itself and the guide rollers 66. The fixed bearings 65 on the fixed plate 64 allow the guide rollers 66 to rotate, thereby ensuring the normal conveyance of the workpiece and achieving the function of guiding and limiting the workpiece, which can effectively reduce the deviation of the workpiece and affect the curing effect. The workpiece is irradiated by the set electron beam generator 67 for curing.

[0030] Specifically, Figure 1-Figure 4 As shown, the gas delivery mechanism includes an air storage box 7, which is fixed on the upper surface of the protective shell 4 and close to one side of the adjusting electric cylinder 5. The left side of the air storage box 7 is connected to a delivery pump 71, and the output end of the delivery pump 71 is connected to a delivery pipe 72. The end of the delivery pipe 72 is connected to the curing part 6. The left side of the protective shell 4 is connected to a protective plate 8, and two slide grooves 9 are provided in the vertical direction inside the protective plate 8. The insides of the two slide grooves 9 are both connected to fixing bolts 10 threadedly connected to the protective shell 4.

[0031] By adopting the above technical solution, the nitrogen stored in the air storage box 7 is extracted by the delivery pump 71, and is delivered to the inside of the curing part 6 through the delivery pipe 72, and is sprayed downward through the vent hole 68 on the curing part 6, so that the nitrogen is sprayed to the surface of the workpiece through the gap between the electron beam generator 67 and the curing part 6, so as to protect the workpiece and reduce the contact with oxygen during curing. The protective plate 8 provided can play a protective role, and the fixing bolts 10 can be loosened to release the fixation of the protective plate 8. With the cooperation of the slide groove 9, the position of the protective plate 8 can be adjusted in the vertical direction. After the adjustment is completed, the fixing bolts 10 are tightened to fix the protective plate 8.

[0032] Working principle: When the workpiece is transported into the protective shell 4, the adjusting electric cylinder 5 drives the curing part 6 to move vertically to adjust the height of the curing part 6. When the curing part 6 moves, it drives the guide roller 66 to move vertically. At this time, the two guide rollers 66 are in contact with the two sides of the workpiece respectively to limit the workpiece. The spring 62 arranged in the mounting cavity 61 can drive the movable plate 63 to move vertically to ensure that the two guide rollers 66 can normally contact the workpiece. Due to the friction generated between the movement of the workpiece itself and the guide roller 66, the guide roller 66 can rotate, thereby ensuring the normal transportation of the workpiece. The electron beam generator 67 irradiates the workpiece for curing. The delivery pump 71 extracts nitrogen and delivers it to the inside of the curing part 6 through the delivery pipe 72, and sprays it downward through the vent 68 on the curing part 6. The nitrogen is sprayed to the surface of the workpiece through the gap, thereby protecting it and reducing the contact with oxygen during curing.
