DETAILED DESCRIPTION

[0030] 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.

[0031] like Figures 1 to 10 As shown, the present invention provides a multi-nozzle installation structure of a UV printer, comprising a main body 1, a slide rail 4 is arranged on the top of the main body 1, a printing box 5 is arranged on the surface of the slide rail 4, and a multi-nozzle printing assembly 7 is arranged inside the printing box 5;

[0032] A fixing mechanism is arranged at the rear end inside the printing box 5, and the fixing mechanism includes a mounting plate 6, which is fixedly connected to the rear end inside the printing box 5, and holes 12 are provided on both sides of the surface of the mounting plate 6. A connecting plate 8 is fixedly installed at the rear end of the multi-nozzle printing assembly 7, and fixing plates 9 are fixedly installed at both ends of the top of the connecting plate 8, and a plug plate 10 is fixedly installed at the bottom end of the fixing plate 9. A limiting hole 11 is provided on the surface of the plug plate 10, and a square plate 18 is fixedly installed at the bottom end of the mounting plate 6. A spring 19 is provided on the opposite side of the square plate 18, and an insert block 20 is provided on the opposite side of the spring 19. Two racks 15 are provided at the bottom end of the mounting plate 6, and a push plate 21 is fixedly installed on the opposite side of the two racks 15. A motor 16 is fixedly installed in the middle of the top of the mounting plate 6, and the output end of the motor 16 passes through the mounting plate 6 downward and is fixedly installed with a gear 17.

[0033] The operator opens the printing box 5, and then the plug plate 10 at the rear end of the multi-nozzle printing assembly 7 can be inserted into the inside of the plug hole 12. When the bottom end of the fixing plate 9 contacts the top end of the mounting plate 6, the plug block 20 will be aligned with the limit hole 11, and then the motor 16 can be driven to rotate the gear 17. Because the gear 17 is engaged with the two racks 15, the gear 17 will drive the two racks 15 to move toward each other when it rotates, and the racks 15 will drive the push plate 21 to move toward each other, and then one side of the push plate 21 will contact the surface of the plug block 20. When the plug block 20 moves, the spring 19 will be stretched, and then the plug block 20 will enter the inside of the limiting hole 11, and then the plug plate 10 can be fixed inside the plug hole 12, and the plug plate 10 will fix the multi-nozzle printing assembly 7 inside the printing box 5, and then the object to be printed can be placed on the top of the conveying assembly 2, and then the conveying assembly 2 can be driven to rotate, moving from the object to the bottom of the multi-nozzle printing assembly 7, and then the multi-nozzle printing assembly 7 will print the corresponding pattern on the surface of the object;

[0034] When the multi-nozzle printing assembly 7 needs to be maintained, the motor 16 can be driven again to make the gear 17 rotate in the opposite direction, and then the gear 17 will drive the rack 15 and the push plate 21 to move relative to each other, and then the push plate 21 will move away from the surface of the plug block 20, and then the stretched spring 19 will pull the plug block 20 out of the limiting hole 11, so that the limiting of the multi-nozzle printing assembly 7 can be cancelled, and then the multi-nozzle printing assembly 7 can be taken out for maintenance.

[0035] like Figure 8 , Fig. 9 and Fig.10 As shown, it also includes: a sealing mechanism, which is arranged at the front end of the printing box 5, the sealing mechanism includes a sealing plate 22, the sealing plate 22 is arranged at the front end of the printing box 5, a connecting plate 23 is fixedly installed at the rear of the top of the sealing plate 22, and a limiting hole 24 is provided at the right end of the connecting plate 23, a fixed shell 25 is fixedly installed at the rear end of the printing box 5, a motor 26 is fixedly installed at the left end inside the fixed shell 25, a screw rod 27 is fixedly installed at the output end of the motor 26, a threaded block 28 is threadedly connected to the surface of the screw rod 27, and a rotating rod 29 is rotatably connected to the middle of the front end of the threaded block 28.

[0036] The above scheme is adopted: through the design of the sealing mechanism, after the multi-nozzle printing assembly 7 is installed, the sealing plate 22 can be placed on the front end of the multi-nozzle printing assembly 7, and the second connecting plate 23 can be inserted into the interior of the rear end of the printing box 5. When the rear end of the sealing plate 22 contacts the rear side of the interior of the printing box 5, the rotating rod 29 can be rotated. When the bottom end of the rotating rod 29 contacts the top end of the second connecting plate 23, the right end of the rotating rod 29 will be aligned with the second limiting hole 24, and then the second motor 26 can be driven to rotate the screw rod 27. Since the screw rod 27 is threadedly connected with the threaded block 28, when the screw rod 27 rotates, the threaded block 28 is driven to move to the left, and then the threaded block 28 pulls the rotating rod 29 to move to the left, and then the right end of the rotating rod 29 enters the interior of the second limiting hole 24, and then the rotating rod 29 can fix the second connecting plate 23, and then the sealing plate 22 can be fixed to the front end of the printing box 5, and then the printing box 5 can be sealed;

[0037] When the multi-nozzle printing assembly 7 needs to be maintained, the motor 26 can be driven again to make the screw 27 rotate in the opposite direction, and then the rotating rod 29 can be moved away from the inside of the limiting hole 24, so that the fixation of the connecting plate 23 can be cancelled, and then the sealing plate 22 can be removed, and then the multi-nozzle printing assembly 7 can be maintained.

[0038] like Fig. 9 and Fig.10 As shown, a support groove 30 is provided on the rear side of the interior of the fixed shell 25, and a support block 31 is slidably connected inside the support groove 30. The front end of the support block 31 is fixedly connected to the rear end of the threaded block 28. A mounting block 32 located at the bottom end of the rotating rod 29 is fixedly installed at the bottom end of the interior of the fixed shell 25. A slide groove 33 is provided on the top of the mounting block 32. The interior of the bottom end of the rotating rod 29 is rotatably connected to a roller 34 located inside the slide groove 33, and the surface of the roller 34 contacts the bottom end of the interior of the slide groove 33.

[0039] The above scheme is adopted: through the design of the support groove 30 and the support block 31, when the threaded block 28 moves, the support block 31 will move inside the support groove 30. Since the size of the support block 31 is adapted to the support groove 30, the threaded block 28 can be limited when the support block 31 moves, ensuring that the threaded block 28 can move normally. Through the design of the mounting block 32, the slide groove 33 and the roller 34, when the rotating rod 29 moves, the roller 34 will be driven to move. Since the surface of the roller 34 contacts the bottom end inside the slide groove 33, the roller 34 will rotate inside the slide groove 33 through the friction between the roller 34 and the slide groove 33, thereby making the rotating rod 29 move more smoothly.

[0040] like Figure 1 and Figure 4As shown, a conveying assembly 2 is arranged inside the top of the main body 1, a fixed box 3 located at the top of the conveying assembly 2 is arranged at the top of the main body 1, a square plate 35 located at the front end of the multi-nozzle printing assembly 7 is fixedly installed inside the printing box 5, a square groove 36 is opened in the middle of the front end of the square plate 35, a square block 37 is arranged inside the square groove 36, and the front end of the square block 37 is fixedly connected to the rear end of the sealing plate 22, T-slots 13 are opened on both sides of the bottom of the mounting plate 6, and a T-block 14 is slidably connected inside the T-slot 13, and the bottom end of the T-block 14 is fixedly connected to the top of the rack 15, and a moving wheel 38 is fixedly installed at the bottom end of the main body 1, and the number of the moving wheels 38 is four, and the array is distributed at the bottom end of the main body 1.

[0041] The above scheme is adopted: through the design of the square plate 2 35, the square groove 36 and the square block 37, when the connecting plate 23 is inserted into the rear end of the printing box 5, the square block 37 will also enter the inside of the square groove 36, and then the square block 37 can support the sealing plate 22, thereby increasing the stability of the fixing of the sealing plate 22, and when the rack 15 moves, the T-block 14 will move inside the T-slot 13, and then the rack 15 can be limited and supported. Through the design of the moving wheel 38, when the equipment needs to move, the device can be pushed, and then the moving wheel 38 will rotate, and then the moving wheel 38 will rotate, and then the moving wheel 38 will drive the entire device to move.

[0042] like Figure 1 and Figure 2 As shown, a square plate three 39 is fixedly installed at the bottom end of the rear side of the main body 1, an electric push rod 40 is fixedly installed at the top of the square plate three 39, the output shaft of the electric push rod 40 passes through the square plate three 39 downward and is fixedly installed with a contact plate 41, a door panel 42 is provided at the front end of the fixed box 3, and the fixed box 3 and the door panel 42 are hinged by a hinge chain 43.

[0043] The above scheme is adopted: through the design of the electric push rod 40 and the contact plate 41, before the equipment is operated, the electric push rod 40 can be driven, and then the output shaft of the electric push rod 40 will push the contact plate 41 down, and then the bottom end of the contact plate 41 will contact the ground, thereby increasing the stability of the equipment operation, and through the design of the door panel 42 and the hinge chain 43, since the fixed box 3 and the door panel 42 are hinged by the hinge chain 43, the door panel 42 can be rotated, and then the fixed box 3 can be opened, and then the electronic components inside the fixed box 3 can be maintained and cleaned.

[0044] like Figure 1 and Figure 7 As shown, the plug block 20 is designed to be longitudinally symmetrical about the center of the mounting plate 6, and the surface of the plug block 20 facing each other is chamfered. A heat sink 44 is provided at the front end of the main body 1, and the heat sink 44 is designed to be longitudinally symmetrical about the center of the main body 1.

[0045] The above scheme is adopted: through the design of the plug block 20, since the plug block 20 is symmetrically designed and the surface on the opposite side is chamfered, it is convenient for the plug block 20 to enter the interior of the limiting hole 11, and the fixing effect of the multi-nozzle printing assembly 7 can be increased. Through the design of the heat sink 44, when the device is working, the external air can pass through the heat sink 44 into the interior of the main body 1, and then the internal electronic components of the main body 1 can be cooled, and the heat sink 44 is symmetrically designed, which can increase the heat dissipation effect of the device.

[0046] The working principle and use process of the present invention:

[0047] First, the operator drives the motor 26 to make the screw rod 27 rotate in the opposite direction, and then the threaded block 28 will move rightward on the surface of the screw rod 27, and then the screw rod 27 will move away from the inside of the limiting hole 24, and then the rotating rod 29 can be rotated in the opposite direction, so that the limit of the limiting hole 24 will be cancelled, and then the sealing plate 22 can be removed, and then the multi-nozzle printing assembly 7 can be placed in the inside of the printing box 5, and the plug plate 10 can be inserted into the inside of the plug hole 12, and then the motor 16 can be driven to rotate the gear 17, and the gear 17 will drive the two racks 15 to move towards each other, and then the T-block 14 will move inside the T-slot 13, and then the rack 15 can be supported, and then the rack 15 will drive the push plate 21 to move, and then the push plate 21 will push the plug block 20 into the inside of the limiting hole 11, and when the plug block 20 moves, the spring 19 will be stretched, and then the plug block 20 can fix the multi-nozzle printing assembly 7 inside the printing box 5;

[0048] After the fixation is completed, the sealing plate 22 can be placed on the front end of the printing box 5 again, and the connecting plate 23 can be inserted into the interior of the rear end of the printing box 5, and then the rotating rod 29 can be rotated. When the rotating rod 29 contacts the top of the connecting plate 23, the roller 34 will enter the interior of the slide groove 33, and then the motor 26 can be driven to rotate the screw rod 27, and the threaded block 28 will move left on the surface of the screw rod 27, and then the right end of the rotating rod 29 will enter the interior of the limiting hole 24, and then the sealing plate 22 can be fixed, and then the object to be printed can be placed on the top of the conveying component 2, and then the conveying component 2 can be driven to rotate, so as to bring the object into the bottom end of the multi-nozzle printing component 7, and then the multi-nozzle printing component 7 can be driven to print on the surface of the object, and finally the operation process is completed.
