Description

Technical Field

[0001] This utility model belongs to the field of paper box printing feeding technology, and in particular relates to a feeding mechanism for paper box printing equipment. Background Technology

[0002] Cardboard packaging, as a mainstream form of commodity packaging, plays a vital role in logistics and sales. Its core functions include product protection, convenient storage and transportation, and promotional display. Compared to other packaging forms such as wooden crates, woven bags, cloth bags, and plastic boxes, cardboard boxes have significant advantages, including readily available raw materials, lightweight design, good printability, simple processing, and high economic efficiency, thus dominating the commercial packaging field. To enhance product recognition and brand promotion, product information and brand logos are typically printed on the flat cardboard surface before box forming. This requires a cardboard box conveying device. For large cardboard box printing, simply placing the boxes orderly on a conveyor belt and then feeding them into the printing unit occupies a large space, and manual placement is time-consuming. Therefore, we propose a feeding mechanism for cardboard box printing equipment that occupies less space, is easy to move, and is suitable for printing equipment of different heights.

[0033] This utility model has the following beneficial effects:

[0034] 1. The feeding platform is positioned at the end of the conveyor belt and on one side of the main feed end of the printing machine. Then, the drive assembly rotates the same group of components, causing the lifting rod to extend out of one side of the first fixed shell under the action of the thread, thus supporting the feeding platform. The casters are off the ground to prevent the feeding platform from slipping. The feeding platform is raised slightly above the conveyor belt according to the height of the conveyor belt, and the paper is placed in the feeding rack. The rotation of the rollers sends the paper onto the conveyor belt and through the printing machine for printing. It does not require too much conveyor belt length at the feeding end, which can save space and reduce the labor cost of manually placing paper. It can also be adapted to conveyor belts of different heights and can transport paper of different sizes, making it highly practical.

[0035] 2. The bottom of the lifting rod is frustum-shaped, with a large contact area with the ground, which can better provide stable support for the feeding platform.

[0036] 3. The drive motor drives the second connecting rod to rotate through the meshing of the first gear and the second gear, which in turn drives the worm gears at both ends to rotate, which in turn drives the two first connecting rods to rotate, and thus drives the four lifting rods to rise and fall synchronously.

[0056] like Figure 1-7As shown, a feeding mechanism for a paper box printing equipment includes a conveyor belt 1, on which a printing machine body 11 is mounted. The printing machine body 11 is a component with printing function, adopting the structure of existing technology, such as the G5-2800 heavy-duty integrated printing machine from the Gerun Explorer series. It also has an internal component for aligning the printed items, which will not be detailed here. A feeding platform 2 is provided on one side of the conveyor belt 1. The bottom of the feeding platform 2 is provided with support legs 21, and the bottom of the four support legs 21 is provided with casters 22 to facilitate the movement of the feeding platform 2 to cooperate with the printing machine body 11 to be operated. A first fixed shell 3 is provided on the outside of the support legs 21. A lifting rod 31 is slidably mounted inside the first fixed shell 3, and the lower end of the lifting rod 31 extends out of the first fixed shell 3. The side of the lifting rod 31 is provided with threads. A second fixed shell 4 is connected between two adjacent first fixed shells 3. A synchronization component is provided inside the second fixed shell 4, and the synchronization component is connected to the lifting rod 31 by threads. The lifting rod 31 is driven to move longitudinally within the first fixed housing 3. A third fixed housing 41 is connected to both ends of the two second fixed housings 4, and the third fixed housing 41 is connected to the side of the support leg 21. One of the third fixed housings 41 is equipped with a drive component for driving the synchronous component to rotate. The feeding platform 2 is equipped with multiple sets of rollers 5, and the wheels of two adjacent sets of rollers 5 are staggered. The rollers 5 are rotatably connected to the feeding platform 2 through a servo motor 51. The rollers 5 and the servo motor 51 are conventional technologies. During operation, the paperboard is gradually pushed by segmented rotation. All of these are debugged and controlled by external control equipment, so they will not be described in detail. The feeding platform 2 is equipped with a feeding rack 6. The circumference of the feeding rack 6 is adjustable. A receiving plate can be rotatably installed on one side of the feeding platform 2 to dock with the end of the conveyor belt 1. Alternatively, a receiving component can be installed externally to make the connection between the feeding platform 2 and the conveyor belt 1 smoother.

[0057] Furthermore, symmetrical limiting grooves 32 are provided on the inner wall of the first fixed shell 3, and the limiting grooves 32 are arranged along the axial direction of the lifting rod 31; the top two ends of the lifting rod 31 are symmetrically provided with limiting blocks 33, which are slidably arranged in the limiting grooves 32, which can prevent the lifting rod 31 from rotating and also limit the length of the lifting rod 31 extending out of the first fixed shell 3, so as to prevent it from detaching from the first fixed shell 3. The bottom of the lifting rod 31 is frustum-shaped, and the contact surface between the lifting rod 31 and the ground is large, which can better provide stable support for the feeding platform 2.

[0058] Furthermore, the synchronization assembly includes a driving bevel gear 7 and a driven bevel gear 71. Both the driving bevel gear 7 and the driven bevel gear 71 are rotatably mounted within the first fixed housing 3, and the driving bevel gear 7 and the driven bevel gear 71 are meshed together. The driven bevel gear 71 has a circular hole with an internal thread in its middle position. The driven bevel gear 71 is sleeved on the side of the lifting rod 31 through the circular hole, and the driven bevel gear 71 is threadedly connected to the lifting rod 31. A first connecting rod 72 is rotatably mounted within the second fixed housing 4. The two ends of the first connecting rod 72 are respectively connected to the driving bevel gears 7 in the first fixed housing 3 on both sides. The drive assembly includes a worm gear 8 and a worm 81. The worm gear 8 is coaxially mounted at one end of the first connecting rod 72, and the worm 81 is rotatably mounted within the second fixed housing 4. Rod 81 is meshed with worm gear 8; a second connecting rod 82 is rotatably provided inside one of the third fixed housings 41, with both ends of the second connecting rod 82 extending into the second fixed housing 4 and connected to the worm gear 81; a drive motor 83 is provided inside the third fixed housing 41, and the output end of the drive motor 83 is connected to a first gear 84; the first gear 84 is rotatably located inside the third fixed housing 41; a second gear 85 is coaxially connected to the side of the second connecting rod 82, and the first gear 84 and the second gear 85 are meshed together. The drive motor 83 drives the second connecting rod 82 to rotate through the meshing of the first gear 84 and the second gear 85, thereby driving the worm gear 81 at both ends to rotate, which in turn drives the two first connecting rods 72 to rotate, and thus drives the four lifting rods 31 to rise and fall synchronously.

[0059] Furthermore, the feeding rack 6 includes a discharge plate 63, a first adjusting plate 61, and a second adjusting plate 62; the two first adjusting plates 61 are symmetrically arranged on both sides of the feeding platform 2, and the lower end of the first adjusting plate 61 is provided with a first pull rod 64, the other end of the first pull rod 64 being slidably inserted into the inside of the feeding platform 2; the second adjusting plate 62 is located at the end of the feeding platform 2 away from the conveyor belt 1, and the lower end of the second adjusting plate 62 is provided with a second pull rod 65, the other end of the second pull rod 65 being slidably inserted into the inside of the feeding platform 2; a first groove 611 is formed on the discharge plate 63, and the discharge plate 63 passes through... The first groove 611 is inserted into the end of the first adjusting plate 61 near the conveyor belt 1; the top of the first adjusting plate 61 is provided with an adjusting screw 66, which is rotatably connected to the first adjusting plate 61 through a bearing, and the adjusting screw 66 is threadedly connected to the discharge plate 63; the first adjusting plate 61 is provided with a positioning block 69, which is located on both sides of the discharge plate 63 to improve the longitudinal stability of the discharge plate 63 and the stability of its connection with the first adjusting plate 61; the bottom of the feeding platform 2 is provided with a first cylinder 67 and a second cylinder 68, and the first cylinder 67 is connected to the first adjusting plate 61. The second cylinder 68 is connected to the second adjusting plate 62. The first cylinder 67 can adjust the distance between the two first adjusting plates 61, and the second cylinder 68 can adjust the distance between the second adjusting plate 62 and the discharge plate 63, thus accommodating cardboard boxes of different sizes. The adjusting screw 66 adjusts the distance between the bottom of the discharge plate 63 and the feeding platform 2, making its height greater than that of one cardboard box but less than the height of two cardboard boxes, thereby ensuring that only one cardboard box is discharged at a time. A partition roller 610 is provided on the side of the second adjusting plate 62 near the conveyor belt 1. The partition roller 610 is located on the second adjusting plate 62. At the lower end, when a large amount of cardboard is placed, the height of the cardboard can be appropriately divided to avoid excessive pressure on the bottom cardboard. The second adjusting plate 62 is inclined longitudinally on the side near the conveyor belt 1, and the discharge plate 63 is inclined longitudinally on the side near the second adjusting plate 62. The inclination direction of the sides of the second adjusting plate 62 and the discharge plate 63 is from top to bottom towards the conveyor belt 1. When the inclination is very small, the cardboard pile itself has a certain inclination, so that the bottom cardboard is closer to one end of the conveyor belt 1, which makes it easier to transport the cardboard.

[0060] The working principle of this utility model is as follows: The feeding platform 2 is pushed to the end of the conveyor belt 1 and located on one side of the feeding end of the printing machine body 11. The drive motor 83, through the meshing of the first gear 84 and the second gear 85, drives the second connecting rod 82 to rotate, thereby driving the worm gears 81 at both ends to rotate, which in turn drives the two first connecting rods 72 to rotate. By driving the active bevel gear 7 to rotate, the driven bevel gear 71 rotates, and the lifting rod 31 moves down out of the first fixed shell 3, supporting the feeding platform 2. The universal wheels 22 are off the ground and will not cause the feeding platform 2 to slip. The feeding platform 2 is raised to a position slightly higher than the conveyor belt 1 according to its height. Depending on the required length of the paperboard to be printed, the distance between the two first adjusting plates 61 can be adjusted by the first cylinder 67, and the distance between the second adjusting plate 62 and the discharge plate 63 can be adjusted by the second cylinder 68, thus accommodating paperboards of different sizes. The adjusting screw 66 adjusts the distance between the bottom of the discharge plate 63 and the feeding platform 2, making its height greater than that of one paperboard but less than that of two paperboards, thereby ensuring that only one paperboard is discharged at a time. The paperboard is placed in the feeding rack 6, and the partition roller 610 can appropriately partition the height of the paperboard to avoid excessive pressure on the bottom paperboard. The paperboard is sent to the conveyor belt 1 by the rotation of the roller 5 and then printed by the printing machine.

[0061] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
