Description

Technical Field

[0001] This utility model relates to the field of color printing machine technology, specifically a color printing machine for packaging boxes. Background Technology

[0002] A printing press is a machine for printing text and images. It generally consists of parts such as plate mounting, inking, printing, and paper feeding. Its main working principle is: first, the text and images to be printed are made into a printing plate and mounted on the printing press. Then, ink is applied to the areas of the printing plate with text and images by hand or by the printing press. Then, the transfer process is carried out to obtain the printed product. A color printing press for packaging boxes is a device specifically used for high-precision color printing on packaging box materials (such as corrugated paper, cardboard, plastic, etc.).

[0003] A search revealed a patent (CN118457058A) for a printing machine used to produce color packaging boxes. The machine includes a worktable with support legs fixedly installed on both sides of its bottom. A housing is fixedly installed on the top of the worktable, with an inlet and an outlet on the lower left and right sides of the housing, respectively. This invention controls the transport of the placement table using a transmission mechanism and limits the packaging box cardboard to prevent movement during transport, ensuring printing quality. A processing mechanism cleans and removes impurities from the surface of the packaging box cardboard, and also performs leveling and dehumidification, reducing paper jams and improving printing quality. The inclusion of separate doors (e.g., door one, door two) facilitates separate maintenance of the internal processing mechanism and inkjet printing unit, reducing maintenance difficulty, costs, and extending the machine's lifespan.

[0004] However, during the use of the device, the packaging cardboard needs to be placed on the placement table manually. Although this step is simple, the frequent operation may consume a lot of manpower and may reduce production efficiency. At the same time, after printing, because the ink is not dry, when the printed packaging cardboard is taken out, the undried ink may get on the operator's hands or the worktable. This not only affects the appearance of the product, but may also cause some trouble for subsequent operations. Utility Model Content

[0005] To address the issues of low efficiency in manually placing cardboard boxes onto the placement table and the impact of undried ink on product aesthetics, this utility model aims to provide a color printing machine for packaging boxes.

[0006] To solve the above technical problems, this utility model adopts the following technical solution: a color printing machine for packaging boxes, including a printing machine body and a cardboard placement bin. A placement table is slidably connected to the outer surface of the printing machine body. An adjusting heating component is provided on the outer surface of the printing machine body. A reciprocating moving component is provided on the outer surface of the cardboard placement bin. The reciprocating moving component includes a half gear. A push plate is slidably connected to the bottom of the cardboard placement bin. A first sliding groove is formed on the outer surface of the cardboard placement bin. An L-shaped plate is slidably connected inside the first sliding groove. The outer end of the L-shaped plate is fixedly connected to the outer side of the push plate. A square toothed plate is fixedly connected to the end away from the push plate. A placement plate is fixedly connected to the outer surface of the cardboard placement compartment. A rotating rod is rotatably connected to the outer surface of the placement plate. A half gear is fixedly connected to the outer end of the rotating rod. A first motor is fixedly connected to the outer surface of the placement plate. One end of the output shaft of the first motor is fixedly connected to the outer end of the rotating rod. A through groove is opened at the bottom of the cardboard placement compartment. The inside of the through groove is slidably connected to the outer surface of the push plate. A plurality of evenly distributed support legs are fixedly connected to the bottom end of the cardboard placement compartment. The toothed groove on the outer surface of the half gear meshes with the toothed groove on the inner side of the square toothed plate.

[0007] Preferably, the adjusting heating assembly includes a heating slot plate, a heating wire fixedly connected inside the heating slot plate, a connecting plate slidably connected to the outer surface of the printing machine body, a plurality of evenly distributed fixing rods fixedly connected to the outer surface of the connecting plate, the end of the fixing rod away from the connecting plate being fixedly connected to the top of the heating slot plate, symmetrically fixed blocks fixedly connected to the outer surface of the printing machine body, a threaded rod rotatably connected to the middle of the fixing block, a second sliding groove symmetrically opened on the outer surface of the printing machine body, the interior of the second sliding groove being slidably connected to the outer end of the connecting plate, and the outer surface of the threaded rod being threadedly connected to the outer surface of the connecting plate.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. By setting up a reciprocating moving component, the pusher plate slides inside the through chute, thereby pushing the cardboard boxes inside the cardboard placement compartment onto the placement table.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Figure 1-4As shown, this utility model provides a color printing machine for packaging boxes. The machine includes a printing machine body 1 and a cardboard placement chamber 2. A placement table 20 is slidably connected to the outer surface of the printing machine body 1. An adjusting heating component is provided on the outer surface of the printing machine body 1. A reciprocating moving component is provided on the outer surface of the cardboard placement chamber 2. The reciprocating moving component includes a half-gear 6. A push plate 9 is slidably connected to the bottom of the cardboard placement chamber 2. A first sliding groove 7 is formed on the outer surface of the cardboard placement chamber 2. An L-shaped plate 8 is slidably connected inside the first sliding groove 7. The outer end of the L-shaped plate 8 is fixedly connected to the outer side of the push plate 9. A square toothed plate 5 is fixedly connected to the end of the L-shaped plate 8 away from the push plate 9. A placement plate 3 is fixedly connected to the outer surface of the cardboard placement chamber 2. A rotating rod 15 is rotatably connected to the outer surface of the placement plate 3. The half-gear 6 is fixedly connected to the outer end of the rotating rod 15. The printing machine body 1 is existing technology (refer to authorized announcement number: CN1184). (57058A) By setting a half gear 6, the push plate 9 slides inside the through groove 16, thereby pushing the cardboard boxes inside the cardboard placement compartment 2 onto the placement platform 20 without the need for manual placement of the cardboard boxes onto the placement platform 20. The outer surface of the placement plate 3 is fixedly connected to a first motor 4, and one end of the output shaft of the first motor 4 is fixedly connected to the outer end of the rotating rod 15, so that the rotation of the output shaft of the first motor 4 can drive the rotating rod 15 to rotate. The bottom of the cardboard placement compartment 2 is provided with a through groove 16, and the inside of the through groove 16 is slidably connected to the outer surface of the push plate 9, so that the push plate 9 can slide inside the through groove 16. The bottom end of the cardboard placement compartment 2 is fixedly connected to multiple evenly distributed support legs 17, so that the cardboard placement compartment 2 can be stably placed on the ground. The tooth groove on the outer surface of the half gear 6 meshes with the tooth groove on the inner side of the square toothed plate 5, so that the rotation of the half gear 6 can drive the square toothed plate 5 to reciprocate.

[0019] The heating adjustment assembly includes a heating slot plate 10, with a heating wire 19 fixedly connected inside the heating slot plate 10. A connecting plate 12 is slidably connected to the outer surface of the printing machine body 1. Multiple evenly distributed fixing rods 11 are fixedly connected to the outer surface of the connecting plate 12. The end of the fixing rod 11 away from the connecting plate 12 is fixedly connected to the top of the heating slot plate 10. Fixed blocks 14 are symmetrically fixedly connected to the outer surface of the printing machine body 1. A threaded rod 13 is rotatably connected to the middle of the fixed block 14. By setting the heating slot plate 10, the heating slot plate 10 can dry the printed packaging cardboard. A second slide groove 18 is symmetrically opened on the outer surface of the printing machine body 1. The interior of the second slide groove 18 is slidably connected to the outer end of the connecting plate 12, so that the connecting plate 12 can slide along the interior of the second slide groove 18. The outer surface of the threaded rod 13 is threadedly connected to the outer surface of the connecting plate 12, so that the rotation of the threaded rod 13 can drive the connecting plate 12 to move.

[0020] Working principle: When in use, the first motor 4 is started. The output shaft of the first motor 4 drives the rotating rod 15 to rotate. The rotating rod 15 drives the half gear 6 to rotate. Since the tooth groove on the outer surface of the half gear 6 meshes with the tooth groove on the inner side of the square toothed plate 5, the rotation of the half gear 6 drives the square toothed plate 5 to reciprocate. The square toothed plate 5 drives the L-shaped plate 8 to slide inside the first slide groove 7. The L-shaped plate 8 drives the push plate 9 to slide inside the through slide groove 16. When the push plate 9 slides to the leftmost side of the through slide groove 16, the cardboard of the packaging box inside the cardboard placement compartment 2 will fall down into the through slide groove 16. Then the push plate 9 slides to the right to push the cardboard of the packaging box until the push plate 9 slides to the rightmost side of the through slide groove 16 and pushes the cardboard of the packaging box out of the through slide groove 16. The pushed cardboard of the packaging box falls onto the placement table 20, so that the cardboard of the packaging box does not need to be manually placed into the placement table 20, reducing manpower consumption and improving production efficiency.

[0021] Then, the threaded rod 13 is rotated. Due to the threaded connection between the threaded rod 13 and the outer surface of the connecting plate 12, the connecting plate 12 moves along the inside of the second slide groove 18. The movement of the connecting plate 12 drives the heating plate 10 to move synchronously through the fixing rod 11. The heating plate 10 can be moved above the printed packaging box cardboard according to the thickness of the packaging box cardboard. At this time, the heating wire 19 is activated. The heat generated by the heating wire 19 will raise the temperature of the outer surface of the heating plate 10 and emit hot air. The hot air emitted from the outer surface of the heating plate 10 can dry the printed packaging box cardboard, ensuring that the pigment dries quickly and preventing undried pigment from staining the operator's hands or workbench, thus ensuring the appearance of the product and facilitating subsequent operation and handling.

[0022] After the cardboard packaging is pushed onto the placement table 20, the printing press body 1 can be started to print on the cardboard packaging. First, according to the front and back width of the cardboard packaging to be printed, the two limiting plates are adjusted by the limiting mechanism to just accommodate the cardboard packaging. Then, the placement table 20 is transported to the right by the conveying mechanism. The placement table 20 enters the machine housing. The starting cylinder one first adjusts the brush bristles at the bottom of the brush handle to contact the surface of the cardboard packaging. The brush bristles can brush off the impurities on the surface of the cardboard packaging to the left during the transport of the cardboard packaging. The impurities are then sucked into the collection box by the collection pump through the wide-mouth air collector and stored. When the placement table 20 moves under the flat plate, the starting cylinder two pushes the pressure plate down to a certain position and energizes the heating resistance wire in the heating plate. The heat is transferred to the flat plate, and while leveling the cardboard packaging, the moisture it contains is evaporated and removed. The placement table 20 continues to be transported to the bottom of the inkjet printing unit to receive the printing work. Finally, the cardboard packaging is pushed out from the discharge port from the placement table 20.

[0023] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0024] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
