Description

Technical Field

[0001] The present invention belongs to the technical field of cigarette case and cigarette label printing, and specifically relates to a rapid shaping and printing device for cigarette case and cigarette label production. Background Art

[0002] A cigarette case is a box for holding cigarettes, and each cigarette case is printed with a cigarette label, which can display different types of tobacco. Currently, most cigarette labels on cigarette cases are three-dimensional cigarette labels. When printing a three-dimensional cigarette label, a cigarette label mold is required, and the cigarette case cardboard is printed with the cigarette label through the cigarette label mold.

[0003] Currently, when using a cigarette label mold to print a cigarette label on a cigarette case cardboard, the cigarette case cardboard is generally conveyed by a conveyor belt. When the cigarette case cardboard is conveyed below the cigarette label mold, it is then printed by the cigarette label mold. During the conveyance, an infrared detector is required to position the cardboard of the cigarette case cardboard. When the cigarette case cardboard is conveyed below the cigarette label mold, a signal is sent to stop the conveyance, and then it is printed by the cigarette label mold. However, through the above method, not only is an infrared detector required, increasing the usage cost, but also each time after the infrared detector detects, a signal is sent and then printing is performed. In this process, system delay and errors are likely to occur, affecting the cigarette label printing effect of the cigarette label mold on the cigarette case cardboard. Moreover, during printing, multiple cigarette case cardboards need to be placed manually in sequence, increasing the labor intensity of people. Therefore, a rapid shaping and printing device for cigarette case and cigarette label production is proposed. Summary of the Invention

[0016] The technical effects and advantages of the present invention:

[0017] 1. During use, place the cigarette box cardboard to be printed into multiple placement frames on the surface of the conveyor belt in sequence. Start the servo motor, which drives the reciprocating lead screw to rotate. The rotation of the reciprocating lead screw drives the lead screw nut to move vertically in a reciprocating manner, and the reciprocating lead screw continuously drives the sector crown gear to rotate. When the lead screw nut drives the moving block to move upward, the sector crown gear will mesh with the first straight gear, and the sector crown gear drives the first straight gear to rotate. The first straight gear drives the rotating rod to rotate, and the rotating rod drives one of the rotating shafts to rotate through two first sprockets and the first chain, thereby driving the conveyor belt to transmit. The conveyor belt drives multiple placement frames to move, so that the cigarette box cardboard in one of the placement frames moves to directly below the printing die. At this time, when the reciprocating lead screw continues to rotate, it will drive the moving block to move downward, and the sector crown gear is separated from the first straight gear. The reciprocating lead screw continues to rotate and drives the moving block and the pressing plate to move downward, while the first straight gear does not rotate and the conveyor belt does not transmit. The pressing plate drives the printing die to move downward until the printing die performs cigarette label printing on the cigarette box cardboard below it. After printing is completed, the reciprocating lead screw continues to rotate and drives the pressing plate and the printing die to move upward. At this time, the sector crown gear meshes with the first straight gear and drives the first straight gear to rotate, so that the conveyor belt transmits again until the cigarette box cardboard in the next placement frame moves to below the printing die, and repeats in sequence, so that cigarette label printing can be performed on multiple cigarette box cardboards. Through the above device, cigarette label printing can be quickly and effectively performed on the surface of the cigarette box, and during printing, it is not necessary to use an infrared detector for positioning processing to position and convey the cigarette box cardboard, reducing the use cost, and avoiding delays and errors in signal transmission, improving the cigarette label printing effect on the cigarette box cardboard, and facilitating people's use;

[0018] 2. During use, stack multiple cigarette box cardboards to be printed and place them in the placement box. The spring and the pressing plate can apply a downward pressure to the multiple cigarette box cardboards. Each time the lead screw nut moves downward, the lead screw nut drives the first rack bar to move downward through the connecting block. During the downward movement of the first rack bar, it will mesh with the second straight gear and drive the second straight gear to rotate forward. The second straight gear drives the third transmission rod to rotate, and the third transmission rod drives the second transmission rod to rotate through two second sprockets and the second chain. The second transmission rod drives the first transmission rod and the blanking roller to rotate through the overrunning clutch. The rotation of the blanking roller can drive the lowermost cigarette box cardboard to move to the right and move out of the placement box and fall into one of the placement frames, enabling automatic blanking of the cigarette box cardboard. When the lead screw nut moves upward, the first rack bar will drive the second straight gear to rotate in the reverse direction at the beginning stage, so that the two second sprockets and the second chain are driven in the reverse direction. Through the set overrunning clutch, the second transmission rod will not drive the first transmission rod and the blanking roller to rotate in the reverse direction;

[0019] 3. Stack multiple cigarette box cardboard sheets to be printed in the placement box. The spring and the pressing plate can apply a downward pressure to the multiple cigarette box cardboard sheets. Each time the conveyor belt drives the multiple placement frames for circular transmission, when one of the placement frames passes below the placement box, the second rack bar at its rear side will rotate in the opposite direction to the fourth spur gear. The fourth spur gear drives the fourth transmission rod to rotate in the opposite direction. Through the meshing of the two third spur gears, the first transmission rod and the blanking roller can be rotated in the forward direction, enabling the lowermost cigarette box cardboard sheet to move to the right simultaneously with this placement frame, so that the cigarette box cardboard sheet falls into this placement frame, and automatic blanking of the multiple cigarette box cardboard sheets can be achieved.

The lower side of the liquid storage tank 4 is fixedly connected with a hose 9. The lower end of the hose 9 is connected with the printing die.

[0034] A vertically arranged strip-shaped opening is formed on the surface of the vertical part of the L-shaped plate 5. A longitudinally arranged moving block 7 is slidably arranged in the strip-shaped opening. A screw nut 8 is fixedly arranged at the rear end of the moving block 7. A reciprocating screw rod 10 is movably inserted in the screw nut 8 in a matching manner. The upper and lower ends of the reciprocating screw rod 10 are respectively rotatably connected with a first fixing plate 11 and a second fixing plate 12 through first bearings. The first fixing plate 11 is fixedly connected with the rear side of the L-shaped plate 5. The second fixing plate 12 is fixedly connected with the rear end of the rear side plate 1. A servo motor 13 is fixedly arranged at the upper end of the first fixing plate 11. The output end of the servo motor 13 is fixedly connected with the upper end of the reciprocating screw rod 10 through a coupling. An intermittent transmission mechanism is arranged at the rear end of the rear side plate 1. The lower end of the reciprocating screw rod 10 extends downward and drives one of the rotating shafts to rotate intermittently through the intermittent transmission mechanism. A group of support rods 14 are fixedly arranged on the lower side of each side plate 1. Each time the intermittent transmission mechanism drives the conveyor belt 2 to transmit, one of the placement frames 3 can be moved directly below the printing die.

[0035] As shown in Figures 2-5As shown, the intermittent transmission mechanism includes a first spur gear 15, a sector crown gear 16, a first chain 17 and two first sprockets 18. The lower end of the reciprocating lead screw 10 is fixedly connected to the sector crown gear 16. The middle part of the rear end of the rear side plate 1 is rotatably inserted with a rotating rod through a second bearing. The rear end of the rotating rod is fixedly connected to the first spur gear 15. The sector crown gear 16 is meshed with the first spur gear 15. The two first sprockets 18 are respectively fixedly sleeved on the rod wall of the rotating rod and the rear end of one of the rotating shafts. The two first sprockets 18 are driven by the first chain 17 to transmit to each other.

[0036] During use, the cigarette box cardboard to be printed is sequentially placed into a plurality of placement frames 3 on the surface of the conveyor belt 2. The servo motor 13 is started. The servo motor 13 drives the reciprocating lead screw 10 to rotate. The reciprocating lead screw 10 rotates to drive the lead screw nut 8 to move vertically back and forth. And the reciprocating lead screw 10 continuously drives the sector crown gear 16 to rotate. When the lead screw nut 8 drives the moving block 7 to move upward, the sector crown gear 16 will be meshed with the first spur gear 15. The sector crown gear 16 drives the first spur gear 15 to rotate. The first spur gear 15 drives the rotating rod to rotate. The rotating rod drives one of the rotating shafts to rotate through the two first sprockets 18 and the first chain 17, so as to drive the conveyor belt 2 to transmit. The conveyor belt 2 drives the plurality of placement frames 3 to move, so that the cigarette box cardboard in one of the placement frames 3 moves to directly below the printing die. At this time, when the reciprocating lead screw 10 continues to rotate, it will drive the moving block 7 to move downward, and the sector crown gear 16 is separated from the first spur gear 15. The reciprocating lead screw 10 continues to rotate to drive the moving block 7 and the pressing plate 6 to move downward, while the first spur gear 15 does not rotate and the conveyor belt 2 does not transmit. The pressing plate 6 drives the printing die to move downward until the printing die performs cigarette label printing on the cigarette box cardboard below it. After printing is completed, the reciprocating lead screw 10 continues to rotate to drive the pressing plate 6 and the printing die to move upward. At this time, the sector crown gear 16 is meshed with the first spur gear 15 and drives the first spur gear 15 to rotate, so that the conveyor belt 2 transmits again until the cigarette box cardboard in the next placement frame 3 is moved to directly below the printing die, and it is repeated in sequence, so that cigarette label printing can be performed on a plurality of cigarette box cardboards. Through the above device, cigarette label printing can be quickly and effectively performed on the surface of the cigarette box, and during printing, it is not necessary to use an infrared detector for positioning processing to position and convey the cigarette box cardboard, reducing the use cost, and avoiding delays and errors in signal transmission, improving the cigarette label printing effect on the cigarette box cardboard, and facilitating people's use.

[0037] As Figure 1 As shown, the front end of the rotating rod extends into the conveyor belt 2 and is fixedly sleeved with a damping sleeve 19. The rear end of the damping sleeve 19 is in close contact with the rear side plate 1 and is slidably arranged. When the sector crown gear 16 is separated from the first spur gear 15, the rotating rod will immediately stop rotating, so that the conveyor belt 2 immediately stops transmitting.

[0038] As Figure 1As shown, two telescopic rods 20 are fixedly arranged at the upper end of the pressing plate 6 and are symmetrically distributed left and right. The upper ends of the two telescopic rods 20 are fixedly connected to the horizontal part of the L-shaped plate 5.

The first rack bar 36 can be meshed with the second straight gear 34. The left side of the placement box 27 is open and is rotationally connected to a baffle 37 through a hinge. During use, a plurality of cigarette box cardboard to be printed are stacked and placed in the placement box 27. The spring 29 and the pressing plate 28 can apply a downward pressure to the plurality of cigarette box cardboard. Each time the lead screw nut 8 moves downward, the lead screw nut 8 drives the first rack bar 36 to move downward through the connecting block 35. During the downward movement of the first rack bar 36, it meshes with the second straight gear 34 and drives the second straight gear 34 to rotate forward. The second straight gear 34 drives the third transmission rod to rotate. The third transmission rod drives the second transmission rod to rotate through the two second sprockets 32 and the second chain 33. The second transmission rod drives the first transmission rod and the blanking roller 30 to rotate through the overrunning clutch 31. The rotation of the blanking roller 30 can drive the lowermost cigarette box cardboard to move to the right and move out of the placement box 27 and fall into one of the placement frames 3, which can automatically blank the cigarette box cardboard. When the lead screw nut 8 moves upward, the first rack bar 36 drives the second straight gear 34 to rotate reversely at the beginning stage, so that the two second sprockets 32 and the second chain 33 are driven reversely. And through the arranged overrunning clutch 31, the second transmission rod does not drive the first transmission rod and the blanking roller 30 to rotate reversely.

[0044] Embodiment 2
