[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figures 1 to 7 As shown, the present invention provides a surface printing device for composite board materials, comprising a main body 1, a slide rail 2 is fixedly installed on the top of the main body 1, a mold 3 is slidably connected to the surface of the slide rail 2, a placement groove 14 is provided on the top of the mold 3, and slide rails 2 4 located above the mold 3 are fixedly installed at both ends of the main body 1, and a printing component 5 is slidably connected to the surface of the slide rail 2 4; A cleaning mechanism is arranged at the top of the printing component 5, and the cleaning mechanism includes a protective shell 6, which is fixedly connected to the top of the printing component 5. A motor 7 is fixedly installed in the inner cavity of the protective shell 6, and a screw 8 is fixedly installed at the output end of the motor 7. The surface of the screw 8 is threadedly sleeved with a threaded plate 9, and both ends are fixedly installed with a U-shaped shell 10. Four rotating rods 11 are rotatably connected to both ends of the surface of the printing component 5, and each two rotating rods 11 are a group, and the opposite sides of the two rotating rods 11 are rotatably connected with a cleaning roller 12, and a sliding rod 13 located inside the rotating rod 11 is fixedly installed inside the U-shaped shell 10, and the sliding rod 13 can slide inside the rotating rod 11.

[0027] The above scheme is adopted: the operator places the mobile phone back cover made of the composite plate inside the placement groove 14, and the printing component 5 can be driven to swing back and forth on the surface of the slide rail 2 4, and the printing component 5 will drive the cleaning roller 12 to swing. During the swinging process, the motor 7 can be driven to rotate the screw rod 8. Since the screw rod 8 is threadedly connected with the threaded plate 9, when the screw rod 8 rotates, the threaded plate 9 moves downward, and the threaded plate 9 drives the U-shaped shell 10 to descend. The U-shaped shell 10 drives the slide rod 13 to slide inside the rotating rod 11, and then the slide rod 13 drives the rotating rod 11 to rotate. The rotating rod 11 drives the cleaning roller 12 to rotate, and then the surface of the cleaning roller 12 contacts the surface of the back cover of the mobile phone. Since the cleaning roller 12 swings back and forth, when it contacts the surface of the back cover of the mobile phone, the cleaning roller 12 rolls on the surface, and then the surface can be cleaned. Finally, the cleaning roller 12 contacts the surface of the back cover of the mobile phone through the driving motor 7, and then the cleaning roller 12 is driven to swing through the printing component 5, and then the surface of the back cover of the mobile phone can be cleaned, so that the ink can be better attached to the back cover of the mobile phone, thereby improving the firmness and clarity of the printed pattern; After the cleaning is completed, the motor 7 can be driven again to make the screw 8 rotate in the opposite direction, and then the threaded plate 9 will pull the U-shaped shell 10 and the slide bar 13 to move upward, and then the slide bar 13 will pull the rotating rod 11 and the cleaning roller 12 away from the surface of the back cover of the mobile phone, and then the printing component 5 can be driven to descend so that the surface of the printing component 5 is close to the surface of the back cover of the mobile phone, and then the printing component 5 can be driven. During the swinging process of the printing component 5, the corresponding pattern can be printed on the surface of the back cover of the mobile phone.

[0028] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, it also includes: a limiting mechanism, which is arranged inside the mold 3, the limiting mechanism includes a limiting rod 19, the limiting rod 19 is fixedly connected to the inside of the mold 3, the surface of the limiting rod 19 is slidably connected to a slider 20, the top of the slider 20 is fixedly installed with a limiting bar 21 located inside the placement groove 14, the number of sliders 20 and limiting bars 21 is multiple, and every two sliders 20 and limiting bars 21 form a group, the bottom end of the mold 3 is rotatably connected to the gear 18 located inside the placement groove 14, the surface of the gear 18 is provided with a fixing groove 22, the bottom end of the slider 20 is fixedly installed with a protrusion 23 located inside the fixing groove 22, a cylinder 15 is fixedly installed on one side of the outer surface of the mold 3, the output shaft of the cylinder 15 is fixedly installed with a connecting plate 16, and one side of the connecting plate 16 is fixedly installed with a toothed plate 17 meshing with the gear 18.

[0029] The above solution is adopted: through the design of the limiting mechanism, before the back cover of the mobile phone is placed in the placement groove 14, the cylinder 15 can be driven to make its output shaft push the connecting plate 16 to move, and the connecting plate 16 will drive the toothed plate 17 to move. Since the toothed plate 17 is engaged with the gear 18, the moving toothed plate 17 will drive the gear 18 to rotate, and then the protrusion 23 will move inside the fixing groove 22, and then the fixing groove 22 will drive the limiting strip 21 to move toward the middle of the placement groove 14; At the same time, the back cover of the mobile phone can be placed in the placement groove 14, and then the cylinder 15 can be driven again to make its output shaft pull the connecting plate 16 to rotate in the opposite direction, and the toothed plate 17 will drive the gear 18 to rotate in the opposite direction, and then the fixed groove 22 will drive the limit bar 21 to move to the two ends inside the back cover of the mobile phone, and then it will contact the inside of the back cover of the mobile phone, so as to limit the back cover of the mobile phone, avoid the position of the back cover of the mobile phone from shifting when the cleaning roller 12 cleans the surface of the back cover of the mobile phone, and thus improve the stability of printing.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, a spring 24 is arranged between the two sliders 20, and the spring 24 is sleeved on the surface of the limit rod 19. A limit rod 25 matching the threaded plate 9 is fixedly installed inside the protective shell 6, and the threaded plate 9 can move along the extension direction of the limit rod 25. There are two limit rods 25, and the two limit rods 25 are designed to be longitudinally symmetrical in the center of the protective shell 6.

[0031] The above scheme is adopted: through the design of the spring 24, when the slider 20 moves to the middle of the placement groove 14, the slider 20 will squeeze the spring 24, and when the gear 18 drives the limit bar 21 to move to the two ends inside the back cover of the mobile phone, the compressed spring 24 will also push the slider 20 and the limit bar 21 to move, thereby increasing the stability of the movement of the slider 20 and the limit bar 21, and the spring 24 is mounted on the surface of the limit rod 19, thereby limiting the spring 24. Through the design of the limit rod 25, when the threaded plate 9 moves, it will move on the surface of the limit rod 25. Since the limit rod 25 is symmetrically designed, the limiting effect on the threaded plate 9 can be increased, ensuring that the threaded plate 9 can move stably.

[0032] like Figure 1 , Figure 6 and Figure 7 As shown, a dustproof box 26 is fixedly installed on the top of the main body 1, an electric push rod 27 is fixedly installed inside the dustproof box 26, and the output shaft of the electric push rod 27 is fixedly connected to one side of the mold 3, the fixing groove 22 is a curved design, the number of the fixing grooves 22 is multiple, and the fixing grooves 22 are distributed in an array of two in a group on the surface of the gear 18.

[0033] The above scheme is adopted: through the design of the dustproof box 26 and the electric push rod 27, after the installation of the back cover of the mobile phone is completed, the electric push rod 27 can be driven so that its output shaft pulls the mold 3 to move on the surface of the slide rail 2, and then the mold 3 is retracted to the inside of the dustproof box 26, and the dustproof box 26 can block the dust in the air and prevent the dust from falling on the surface of the mobile phone shell, and then through the cooperation between the tooth plate 17 and the printing component 5, all the back covers of the mobile phones can be printed, and through the design of the fixed groove 22, since the fixed groove 22 is a curved design, when the gear 18 rotates, it can drive the slider 20 and the limit strip 21 to move relative or toward each other.

[0034] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a square hole is opened inside the placement groove 14, and the limiting strip 21 can move inside the square hole. There are two cleaning rollers 12 and two slide bars 13, and they are designed to be longitudinally symmetrical about the center of the printing component 5. The slide bar 13 is smooth in design.

[0035] The above scheme is adopted: through the design of the placement groove 14 and the limit bar 21, when the limit bar 21 moves, it will move inside the square hole, so that the placement groove 14 will not interfere with the movement of the limit bar 21, and the inner wall of the square hole fits with the surface of the limit bar 21, so that the square hole can limit the limit bar 21, and through the design of the cleaning roller 12 and the slide bar 13, since the cleaning roller 12 and the slide bar 13 are symmetrically designed, the two cleaning rollers 12 can clean the surface of the back cover of the mobile phone at the same time, which will improve its cleaning efficiency, and the slide bar 13 is smooth in design, so that the slide bar 13 can move more smoothly inside the rotating rod 11.

[0036] like Figure 1 , Figure 3 and Figure 6 As shown, a fixing hole is opened on one side of the mold 3, and the tooth plate 17 can slide inside the fixing hole. A baffle is provided at the bottom end of the limiting rod 25, and when the threaded plate 9 descends, it can contact the surface of the baffle.

[0037] The above scheme is adopted: through the design of the mold 3 and the tooth plate 17, since a fixing hole is opened on one side of the mold 3, when the tooth plate 17 moves, it will enter the inside of the fixing hole, and the mold 3 will not interfere with the movement of the tooth plate 17. Through the design of the limiting rod 25, since a baffle is provided at the bottom end of the limiting rod 25, when the thread plate 9 moves and contacts the surface of the baffle, the movement of the thread plate 9 can be blocked to prevent the thread plate 9 from detaching from the surface of the limiting rod 25.

[0038] The working principle and use process of the present invention: First, the operator can drive the cylinder 15 to make the connecting plate 16 drive the tooth plate 17 to move, the tooth plate 17 will drive the gear 18 to rotate, the protrusion 23 will move inside the fixing groove 22, and then the fixing groove 22 will drive the limiting strip 21 to move toward the middle of the placement groove 14; then the mobile phone back cover made of the composite plate can be put into the placement groove 14, and then the cylinder 15 can be driven again, so that its output shaft pulls the connecting plate 16 to rotate in the opposite direction, the tooth plate 17 will drive the gear 18 to rotate in the opposite direction, and then the fixing groove 22 will drive the limiting strip 21 to move toward both ends of the inside of the mobile phone back cover, and then it will contact with the inside of the mobile phone back cover, so that the mobile phone back cover can be limited; After the fixing is completed, the printing assembly 5 can be driven to reciprocate on the surface of the slide rail 2 4. When the printing assembly 5 moves, the driving motor 7 rotates the screw rod 8, and then the threaded plate 9 moves down on the surface of the screw rod 8, and the threaded plate 9 drives the U-shaped shell 10 and the slide rod 13 to descend, and then the slide rod 13 slides inside the rotating rod 11, and pushes the rotating rod 11 to rotate, and the rotating rod 11 drives the cleaning roller 12 to move toward the surface of the mobile phone back cover, and then the surface of the cleaning roller 12 contacts the surface of the mobile phone back cover. Since the cleaning roller 12 swings back and forth, when it contacts the surface of the mobile phone back cover, the cleaning roller 12 rolls on its surface, and then the surface can be cleaned; after the cleaning is completed, the motor 7 can be driven again to rotate the screw rod 8 in the opposite direction, so that the slide rod 13 pulls the rotating rod 11 and the cleaning roller 12 away from the surface of the mobile phone back cover, and then the printing assembly 5 can be driven to descend, so that the surface of the printing assembly 5 is close to the surface of the mobile phone back cover, and then the printing assembly 5 can be driven. In the process of the swinging of the printing assembly 5, the corresponding pattern can be printed on the surface of the mobile phone back cover, and the operation process is finally completed.
