Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, and more specifically, to a printing device capable of adaptively adjusting printing height. Background Art

[0002] Tobacco is an annual herb of the genus Nicotiana in the family Solanaceae. Its leaves are oblong-lanceolate, lanceolate, oblong or ovate, gradually pointed at the apex and narrowed at the base to become ear-shaped and semi-amplexicaul. Its petioles are inconspicuous or wing-shaped. The inflorescence is conical, the calyx is tubular or tubular-bell-shaped, the lobes are triangular-lanceolate, the corolla is funnel-shaped, light yellow, light green, red or pink, with yellow at the base. The capsule is ovoid or elliptical, almost as long as the persistent calyx. The seeds are round or broadly oblong and brown. The flowering and fruiting period is summer and autumn.

[0003] When tobacco is processed into cigarettes, it is often packaged so that it can be easily transported and sold. Most of the existing cigarette packaging uses paper packaging. In order to increase its aesthetics, existing tobacco companies often print cigarette packaging paper. At this time, a printing device is used. However, the thickness of different packaging papers is often inconsistent, and many packaging papers are often stacked together during the printing process. This causes the height of the packaging paper stack to continue to increase during the printing process. Therefore, it is necessary to continuously adjust the printing height during the printing process to adapt to the height of the packaging paper stack. The existing height adjustment method is divided into manual adjustment and automatic adjustment. Since the thickness of the packaging paper is thin, fine-tuning is involved, which makes manual adjustment time-consuming and labor-intensive, and the accuracy is not high. The cost of the existing automatic fine-tuning structure is very high, and the maintenance process is very inconvenient, so it needs to be improved. Utility Model Content

[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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0026] like Figures 1 to 6 As shown, the utility model provides a printing device capable of adaptively adjusting printing height, comprising:

[0027] The box body 1 has a rotating shaft 2 movably sleeved inside the left side of the box body 1, a driven roller 3 fixedly sleeved on the outer surface of the rotating shaft 2, and a support block 4 fixedly installed inside the box body 1;

[0028] An adjustment mechanism is provided on the outer surface of the box body 1;

[0029] Among them, the adjustment mechanism includes a guide block 5 and a limit rod 10. The outer surface of the guide block 5 is fixedly connected to the outer surface of the top left side of the front and back of the box body 1. A pressure rod 6 is fixedly installed on the left side of the guide block 5. The bottom end of the pressure rod 6 is movably connected to the fixing frame 7. The bottom end of the fixing frame 7 is fixedly installed with a base 8. A baffle 9 is fixedly installed on the left side of the pressure rod 6. The outer surface of the limit rod 10 is movably connected to the outer surface of the box body 1. The bottom end of the limit rod 10 is fixedly connected to the top of the base 8. A round rod 12 is fixedly installed inside the limit rod 10. The outer surface of the round rod 12 is movably sleeved with a movable block 11. The outer surface of the movable block 11 is fixedly connected to the outer surface of the box body 1. A spring 13 is fixedly installed on the top of the movable block 11. The inside of the spring 13 is movably sleeved with the outer surface of the round rod 12, and the top of the spring 13 is fixedly connected to the top inside the limit rod 10.

[0030] When the wrapping paper is at the top of the fixed frame 7, since the wrapping paper has a certain thickness, the two pressure rods 6 will be squeezed, causing the two pressure rods 6 to move. At this time, the two pressure rods 6 drive the box body 1 to move as a whole through the guide block 5. Due to the limitation of the two limit rods 10, the box body 1 will drive the two groups of movable blocks 11 to move upward, so that the printing height can be automatically adjusted according to the stacking thickness of the printing paper. At the same time, the four springs 13 will be compressed in the upward movement of the two groups of movable blocks 11. Due to the elastic force of the four springs 13, the two pressure rods 6 will always be able to press the wrapping paper tightly, and the box body 1 as a whole will have a good reset effect.

[0031] A motor 14 is fixedly mounted on the right side of the front of the box body 1 , and a rotating shaft 15 is fixedly sleeved on the other end of the output shaft of the motor 14 .

[0032] When the motor 14 is running, the rotating shaft 15 will rotate.

[0033] Among them, the outer surface of the rotating shaft 15 is fixedly sleeved with a driving roller 16, and the driving roller 16 is connected to the driven roller 3 through a transmission belt 17. The inside of the transmission belt 17 is movably connected to the top of the support block 4, and the outer surface of the transmission belt 17 is fixedly installed with a pushing block 18.

[0034] When the rotating shaft 15 rotates, it will drive the driving roller 16 to rotate. At this time, the driving roller 16 will drive the driven roller 3 to rotate through the transmission belt 17. At this time, several pushing blocks 18 will move under the drive of the transmission belt 17. At this time, the packaging paper at the top of the transmission belt 17 will move to the left under the drive of several pushing blocks 18.

[0035] A limit block 19 is fixedly mounted on the top of the guide block 5 , a circular shaft 20 is movably sleeved inside the left side of the limit block 19 , and a printed board 21 is fixedly mounted on the bottom end of the circular shaft 20 .

[0036] Due to the design of the limit block 19, the movement of the two circular shafts 20 will be limited, so that the two circular shafts 20 can only drive the printing plate 21 to move up and down. When the printing plate 21 moves downward, the packaging paper at its bottom will be printed.

[0037] A square rod 22 is fixedly sleeved inside the top end of the circular shaft 20 , and fixing blocks 23 are fixedly installed on both the front and rear sides of the bottom end of the square rod 22 .

[0038] When the fixing block 23 moves up and down, the two circular shafts 20 are driven to move up and down through the square rod 22 .

[0039] Among them, a connecting block 24 is fixedly installed on the left side of the limit block 19, and a driven wheel 25 is movably sleeved on the outer surface of the other end of the connecting block 24. An extrusion shaft 26 is fixedly installed on the outer surface of the driven wheel 25, and the outer surface of the extrusion shaft 26 is movably connected to the inside of the fixed block 23.

[0040] When the driven wheel 25 rotates, the extrusion shaft 26 will rotate driven by the driven wheel 25 , and then the outer surface of the extrusion shaft 26 will squeeze the inside of the fixed block 23 during the rotation, causing it to move up and down.

[0041] Among them, driving wheels 27 are fixedly installed at the front and rear ends of the rotating shaft 2, and the driving wheel 27 is connected to the driven wheel 25 through a transmission bar 28.

[0042] When the rotating shaft 2 rotates, it will drive the two driving wheels 27 to rotate respectively, and then the driving wheel 27 will drive the driven wheel 25 to rotate through the transmission bar 28.

[0043] The working principle and use process of this utility model:

[0044] First, the operator starts the motor 14, and the rotating shaft 15 will drive the driving roller 16 to rotate. Then the driving roller 16 will drive the driven roller 3 and the rotating shaft 2 to rotate through the transmission belt 17. In this process, several pushing blocks 18 will reciprocate under the drive of the transmission belt 17. At this time, the operator places the packaging paper to be printed on the top of the transmission belt 17. At this time, several pushing blocks 18 will push the packaging paper to move to the left. Subsequently, the packaging paper will contact the guide block 5, the pressure rod 6 and the fixing frame 7 in turn during the left movement. Due to the design of the shape of the fixing frame 7, when the left end of the packaging paper contacts the fixing frame 7, it will be guided to the top of the fixing frame 7. Since the paper has a certain thickness, when the packaging paper When the paper is at the top of the fixed frame 7, the two pressure rods 6 will be squeezed and pushed, so that the two pressure rods 6 will drive the box body 1 to move as a whole through the guide block 5. At this time, the box body 1 will simultaneously drive the two groups of movable blocks 11 to move. Due to the design of the two limit rods 10, the movement of the two groups of movable blocks 11 will be limited so that they can only move up and down. At this time, the box body 1 as a whole will drive the two groups of movable blocks 11 to move upward along the inside of the two limit rods 10, thereby realizing the function of automatically adjusting the printing height according to the thickness of the printed paper stack. At the same time, the four springs 13 will be compressed during the upward movement of the two groups of movable blocks 11. Due to the elastic force of the four springs 13, the two groups of movable blocks 11 will have a good reset effect.

[0045] At the same time, when the rotating shaft 2 rotates, it will drive the two driving wheels 27 to rotate at the same time. At this time, the two driving wheels 27 will drive the two driven wheels 25 to rotate with the connection point with the two connecting blocks 24 as the axis through the two transmission bars 28. Then the two driven wheels 25 will respectively drive the two extrusion shafts 26 to rotate. At this time, the outer surfaces of the two extrusion shafts 26 will squeeze and push the inside of the two fixed blocks 23 during rotation, so that the two fixed blocks 23 drive the square rod 22 to move. At this time, the square rod 22 will simultaneously drive the two circular shafts 20 to move. Due to the design of the limit block 19, the movement of the two circular shafts 20 will be limited so that it can only move up and down. In this case, the two circular shafts 20 will repeatedly move up and down along the inside of the limit block 19 driven by the square rod 22. When the circular shaft 20 drives the printing plate 21 to move downward, the printing plate 21 will print the packaging paper located below it, thereby realizing the function of automatically printing the packaging paper.
