[0002] UV spraying refers to spraying UV paint on the surface of an object. UV paint refers to paint that is cured by ultraviolet light radiation. The surface of the object is sprayed reciprocatingly by CNC to ensure that the UV paint on the surface of the object is sprayed evenly and completely.

[0003] The existing CNC reciprocating UV spraying line, for example, a reciprocating UV automatic spraying device proposed in patent application number "CN202321470848.1", can perform reciprocating automatic spraying on the plates on the conveyor belt through structures such as a reciprocating mechanism, a connecting block, and a paint nozzle, thereby solving the problem in the prior art that the plates are difficult to spray evenly.

[0004] However, it can only spray UV coating on the surface of the object, but cannot cure the UV coating in time. The surface of the sprayed object is prone to dust and other impurities during the transmission process, which affects the aesthetics of the UV coating after curing. Therefore, a CNC reciprocating UV spraying line is proposed. Utility Model Content

DETAILED DESCRIPTION

[0021] 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 of 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.

[0022] A numerically controlled reciprocating UV spraying line comprises a transmission seat 1, the upper end of which is fixedly connected to a frame 3, the upper end of which is plugged with three groups of partitions 4, the three groups of partitions 4 are all located inside the frame 3, and a spraying chamber 6 and a curing chamber 7 are formed between the three groups of partitions 4 and the inner wall of the frame 3, the top of the inner wall of the frame 3 is located in the spraying chamber 6 and is slidably connected to a spraying assembly, and the top of the inner wall of the frame 3 is located in the curing chamber 7 and is fixedly connected to an ultraviolet lamp board 21.

[0023] like Figure 1-Figure 3 As shown, by placing the spray chamber 6 and the curing chamber 7 adjacent to each other and located inside the same frame 3, the transmission seat 1 transmits the article. When the article is about to enter the spray chamber 6, the three groups of partitions 4 are controlled to be lifted so that the article can smoothly enter the spray chamber 6, and the three groups of partitions 4 are lowered to isolate the spray chamber 6 from the curing chamber 7. After the article is sprayed with UV paint by the spraying assembly, the three groups of partitions 4 are lifted again, and the article is transmitted to the curing chamber 7 and cured by the ultraviolet light emitted by the ultraviolet lamp board 21 to prevent dust and other impurities from sticking to the surface of the sprayed article during the transmission process. The entire UV spraying line is an automatic assembly line mode. While the previous article is being cured, the next article is being sprayed with UV paint, and the spraying efficiency is relatively high.

[0024] The upper ends of the three groups of partitions 4 are commonly fixed with two groups of connecting frames 5, and a connecting plate 8 is fixed between the two groups of connecting frames 5. The upper end of the frame 3 is rotatably connected to a reciprocating screw rod 10, which is threadedly connected to the connecting plate 8, and the reciprocating screw rod 10 and the upper end of the frame 3 are perpendicular to each other.

[0025] like Figure 1-Figure 2 As shown, when the reciprocating screw rod 10 is driven to rotate, since the partition plate 4 is plugged into the top of the frame 3, the rotation of the reciprocating screw rod 10 will drive the connecting plate 8 to rise and fall, so that the connecting plate 8 drives the three groups of partition plates 4 to rise and fall through the connecting frame 5.

[0026] A servo motor 11 is fixedly connected to the upper end of the frame 3, a driving gear 12 is fixedly connected to the output end of the servo motor 11, a transmission gear 9 is fixedly connected to the bottom of the side wall of the reciprocating screw rod 10, and the transmission gear 9 is meshed with the driving gear 12 for transmission.

[0027] like Figure 1-Figure 2As shown, the servo motor 11 is fixed to the upper end of the frame 3 through an L-shaped plate. The servo motor 11 drives the driving gear 12 to rotate, so that the driving gear 12 drives the transmission gear 9 to rotate, thereby rotating the reciprocating screw rod 10.

[0028] The inner wall of the frame 3 is located in the spray chamber 6 and is fixedly connected with two groups of slides 15, the two groups of slides 15 are parallel to each other, the spray assembly includes a movable frame 16, the movable frame 16 is slidably connected between the slides 15 and the top of the spray chamber 6, the lower end of the movable frame 16 is fixedly connected with a fixed frame 17, the fixed frame 17 is located between the two groups of slides 15, and the lower end of the fixed frame 17 is fixedly connected with a nozzle 18.

[0029] like Figure 1-Figure 3 As shown, two sets of slide plates 15 support and limit the spray assembly, so that the spray assembly slides back and forth above the inside of the spray room 6, and sprays UV paint to the objects in the spray room 6 through the spray head 18.

[0030] The inner wall of the movable frame 16 is symmetrically fixed with two groups of linear racks 19, the upper end of the frame 3 is fixed with a servo motor 13, the output end of the servo motor 13 is fixed with a turntable 14, and the side wall of the turntable 14 is fixed with an arc rack 20, which meshes with the two groups of linear racks 19.

[0031] like Figure 1-Figure 3 As shown, the servo motor 13 drives the turntable 14 to rotate, and the length of the arc rack 20 is one-fourth of the circumference of the turntable 14. When the turntable 14 rotates, the arc rack 20 meshes with the two sets of linear racks 19 in turn to drive the moving frame 16 to move back and forth, so that the nozzle 18 sprays the UV coating back and forth.

[0032] A mounting plate 23 is fixedly connected to one end of the frame 3 away from the curing chamber 7 , and a blower 22 is fixedly connected to the mounting plate 23 .

[0033] like Figure 1-Figure 3 As shown, the articles before entering the spraying room 6 pass through the blower 22, and the wind blown by the blower 22 blows away impurities such as dust that fall on the surface of the articles, thereby reducing impurities on the surface of the articles and increasing the smoothness of the UV spraying effect.

[0034] The working principle of a CNC reciprocating UV spraying line provided by the utility model is as follows:

[0035] By placing the spraying room 6 and the curing room 7 adjacent to each other and inside the same frame 3, the transport seat 1 transports the article. When the article is about to enter the spraying room 6, the three groups of partitions 4 are controlled to be lifted so that the article can smoothly enter the spraying room 6. The three groups of partitions 4 are lowered to isolate the spraying room 6 from the curing room 7. After the article is sprayed with UV paint by the spraying assembly, the three groups of partitions 4 are lifted again, and the article is transported to the curing room 7 and cured by the ultraviolet light emitted by the ultraviolet lamp board 21, so as to prevent dust and other impurities from sticking to the surface of the sprayed article during the transportation process.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
