Description

Technical Field

[0001] This utility model relates to the field of packaging box printing technology, specifically to a gift packaging box printing device. Background Technology

[0002] A packaging box printing machine is a device used to print text and images on the surface of packaging boxes. Its working principle involves creating a printing plate with pre-designed text and images, then using a printing press to evenly apply ink to the areas of the printing plate containing the text and images. This ink is then transferred to the surface of the packaging box, creating a printed copy identical to the printing plate. Packaging box printing machines are widely used in the production of various packaging boxes, especially in the printing of cardboard boxes, corrugated cardboard, and other packaging materials. Through efficient and precise printing technology, the aesthetics and brand image of packaging boxes can be enhanced.

[0003] Existing packaging box printing equipment has the following shortcomings:

[0004] Most existing devices lack a blowing structure, resulting in slow ink drying and the need to wait for the ink to solidify before removing the packaging box, which reduces printing efficiency. In addition, paper scraps or dust on the surface of the packaging box are not blown away in time, which can easily lead to blurred or mixed printing patterns, thus reducing the printing effect.

[0005] Most existing devices are unable to flatten and limit the packaging boxes. If the packaging boxes are not placed flat or wrinkled during transportation, it will greatly affect the printing effect. At the same time, it will also cause the printed packaging boxes to fail to meet the usage standards and be discarded, which increases printing costs and wastes packaging boxes.

[0032] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0034] Reference Figures 1 to 8 As shown, a gift packaging box printing device includes a base plate 1, a support plate 2, and a side plate 3, with the support plate 2 and the side plate 3 respectively fixed at both ends of the base plate 1.

[0035] It also includes a controller, a printing mechanism, a flattening mechanism, and a blower mechanism;

[0036] The printing mechanism is located between the support plate 2 and the side plate 3. The printing mechanism includes a screen plate 4, a printing frame 5, a guide assembly and a pushing assembly. The printing frame 5 is slidably mounted on the side plate 3. The screen plate 4 is fixed to the bottom of the printing frame 5 by bolts. The guide assembly is fixed to the top of the printing frame 5 and the pushing assembly is mounted on the printing frame 5.

[0037] The flattening mechanism is located between the base plate 1 and the support plate 2. The flattening mechanism includes a lifting assembly, a connecting assembly and two pressure rods 6. The lifting assembly is located on the outer wall of the support plate 2, the connecting assembly is located on the lifting assembly, and both pressure rods 6 are located on the connecting assembly.

[0038] The blower is mounted on the support plate 2. The blower assembly includes a position sensor 7 and a rotating component. The rotating component is inserted into the outer wall of the support plate 2. The position sensor 7, the lifting component, and the pushing component are all electrically connected to the controller.

[0039] Reference Figures 1 to 8As shown, the guide assembly includes a slide plate 8, two guide rods 9, and four L-shaped blocks 10. The four L-shaped blocks 10 are symmetrically arranged on the printing frame 5. Each guide rod 9 is fixed between every two L-shaped blocks 10. The slide plate 8 is slidably disposed between two guide rods 9. When the second connecting rod 13 pushes the connecting block 14 to make the first scraper 15 fit tightly against the screen 4 and the second scraper 16 moves away from the screen 4, since each L-shaped block 10 is fixedly connected to the printing frame 5, and each guide rod 9 is fixedly connected to two of the L-shaped blocks 10, and the two ends of the slide plate 8 are slidably connected to the two guide rods 9 respectively, and the connecting block 14 is hinged to the slide plate 8, the connecting block 14 pushes the slide plate 8 along the direction of the guide rods 9. The first scraper 15 slides away from the first motor 11, causing it to slide on top of the screen 4. This allows the first scraper 15 to evenly distribute ink on the top of the screen 4. Then, as the output end of the first motor 11 continues to rotate, the second connecting rod 13 pulls the connecting block 14, causing the second scraper 16 to fit tightly against the screen 4. The first scraper 15 moves away from the screen 4, simultaneously pulling the slide plate 8 towards the first motor 11. This allows the second scraper 16 to slide on top of the screen 4, scraping away excess ink and improving the printing effect. After printing the packaging box is completed, the worker disconnects the first motor 11 via the controller.

[0040] Reference Figures 1 to 8As shown, the pushing assembly includes a first motor 11, a first connecting rod 12, a second connecting rod 13, a connecting block 14, a first scraper 15, and a second scraper 16. The first motor 11 is fixedly mounted on the printing frame 5, the first connecting rod 12 is fixedly mounted on its output end, the second connecting rod 13 is hinged to the end of the first connecting rod 12 away from the first motor 11, and the connecting block 14 is hinged to the outer wall of the end of the second connecting rod 13 away from the first connecting rod 12. Furthermore, one sidewall of the slide plate 8 is hinged to the end of the connecting block 14 away from the second connecting rod 13. Both scraper 15 and scraper 16 are fixedly mounted on the bottom of connecting block 14. First motor 11 is electrically connected to controller. When the two pressure rods 6 flatten the packaging box, the bottom of U-shaped block 18 is completely flush with the top of base plate 1, thus ensuring the bottom of screen plate 4 is completely flush with the surface of the packaging box. Then, the worker adds the ink required for printing to the top of screen plate 4. The worker then starts first motor 11 via controller. Since first connecting rod 12 is fixedly connected to the output end of first motor 11, first connecting rod 12 and... The second connecting rod 13 is hinged, and the connecting block 14 is hinged to the second connecting rod 13. Additionally, the slide plate 8 is hinged to the connecting block 14. The first scraper 15 and the second scraper 16 are both fixedly connected to the connecting block 14. Therefore, when the output end of the first motor 11 rotates, it drives the first connecting rod 12 and the second connecting rod 13 to rotate simultaneously. This causes the second connecting rod 13 to push the connecting block 14 to rotate, thereby causing the first scraper 15 to fit tightly against the wire mesh plate 4, and the second scraper 16 to move away from the wire mesh plate 4. It should be noted that when the output end of the first motor 11... When the first connecting rod 12 rotates from 0 to 180 degrees, the ink on the top of the screen plate 4 is scraped onto the packaging box once by the bottom of the first scraper 15. At this time, the bottom of the second scraper 16 does not contact the screen plate 4. When the output end of the first motor 11 drives the first connecting rod 12 to rotate from 180 to 360 degrees, the ink on the top of the screen plate 4 is scraped back onto the packaging box once by the bottom of the second scraper 16. At this time, the bottom of the first scraper 15 does not contact the screen plate 4. This process is repeated to achieve thorough printing on the packaging box.

[0041] Reference Figures 1 to 8As shown, the lifting assembly includes a cylinder 17 and a U-shaped block 18. The cylinder 17 is fixedly mounted on the top of the support plate 2 via a connecting plate 19. The U-shaped block 18 is fixedly mounted on the output end of the cylinder 17 and is fixedly connected to the printing frame 5. The cylinder 17 is electrically connected to the controller. Before printing on the packaging box, the worker places the packaging box horizontally on the top of the base plate 1. Then, the worker starts the cylinder 17 through the controller, causing the output end of the cylinder 17 to extend downward. Since the U-shaped block 18 is fixedly connected to the output end of the cylinder 17 and is also fixedly connected to the printing frame 5, and the other end of the printing frame 5 is slidably connected to the side plate 3, the cylinder 17 drives the printing frame 5 to descend. Since the screen plate 4 is fixedly connected to the printing frame 5, and the guide component and the push component are both designed on the printing frame 5, the cylinder 17 drives the screen plate 4, the guide component, and the push component to descend vertically at the same time. Since each rotating plate 20 is hinged to the U-shaped plate, the cylinder 17 drives the two rotating plates 20 to descend.

[0042] Reference Figures 1 to 8 As shown, the connecting assembly includes two rotating plates 20, two sliders 21, and four rollers 22. Each rotating plate 20 is rotatably mounted on a U-shaped block 18, and each slider 21 is hinged to the bottom of one rotating plate 20. The four rollers 22 are symmetrically arranged at the bottom of the two sliders 21, and each pair of rollers 22 is hinged to the bottom of one slider 21. When the cylinder 17 drives the two rotating plates 20 to descend, since each slider 21 is hinged to a rotating plate 20, the cylinder 17 drives the two sliders 21 to descend simultaneously. When the bottoms of the four rollers 22 contact the top of the base plate 1, since each pair of rollers 22 is rotatably connected to the bottom of one slider 21, and each rotating plate 20 is hinged to the top of one slider 21, and the top of the base plate 1 is... The device has two grooves 30 for four rollers 22 to roll, so that the four rollers 22 roll in the two grooves 30 respectively, thereby driving the two sliders 21 to slide in the horizontal direction. This causes the two sliders 21 to first contact the grooves 30 and then move away from each other inside the two grooves 30, so that the two rotating plates 20 change from a vertical state to a horizontal state. This causes the two pressure rods 6 to descend to contact the surface of the packaging box and then move away from each other. Since each pressure rod 6 is fixedly connected to a slider 21, the two pressure rods 6 cooperate to flatten the packaging box to prevent wrinkles on the surface of the packaging box from affecting printing. After the two pressure rods 6 have finished flattening the packaging box, the worker disconnects the electric cylinder 17 through the controller to facilitate the subsequent printing work on the packaging box.

[0043] Reference Figures 1 to 8As shown, the rotating assembly includes a second motor 23, several fans 24, several hinge shafts 25, several synchronous pulleys 26, and several synchronous belts 27. Each hinge shaft 25 is rotatably mounted on the support plate 2. Each fan 24 is fixedly mounted on one end of a hinge shaft 25. Each synchronous pulley 26 is fixedly mounted on the other end of a hinge shaft 25. The second motor 23 is fixedly mounted on the support plate 2, and the end of one of the hinge shafts 25 is fixedly connected to the output end of the second motor 23. Each synchronous belt 27 is fitted onto two adjacent synchronous pulleys 26. Between these components, the second motor 23 is electrically connected to the controller. When the two pressure rods 6 work together to flatten the packaging box, the position sensor 7 senses that one of the pressure rods 6 is approaching, and sends this signal to the controller. The controller then starts the second motor 23. Since each hinge shaft 25 is rotatably connected to the support plate 2, each fan 24 is fixedly connected to one end of one hinge shaft 25, and each synchronous pulley 26 is fixedly connected to the other end of one hinge shaft 25, and the output end of the second motor 23 is fixed to the end of one of the hinge shafts 25... The connection is such that each synchronous belt 27 is sleeved with two adjacent synchronous pulleys 26, so that several fans 24 rotate simultaneously. When the worker cuts off the power to the first motor 11 through the controller, the worker starts the cylinder 17 through the controller, causing the output end of the cylinder 17 to retract. As a result, the position sensor 7 senses the distance of one of the pressure rods 6 and sends this signal to the controller, which cuts off the power to the second motor 23, thereby stopping the rotating component. It should be noted that when the packaging box is flattened, several fans 24 start once to blow air on the flattened packaging box surface, which can remove dust and paper scraps, thereby avoiding the impact of dust and paper scraps on printing and improving the printing effect. After printing is completed, the fans 24 continue to blow air on the packaging box to dry the printing ink on the packaging box, improve printing efficiency, and facilitate the rapid printing of the next packaging box. When the ink dries, the cylinder 17 drives the two pressure rods 6 to reset. After the position sensor 7 detects that the pressure rods 6 have moved away, it sends a signal to the controller, thereby cutting off the power to the second motor 23, so that several fans 24 stop rotating and stop blowing air.

[0044] Reference Figures 1 to 8 As shown, two guide rails 28 are fixedly installed on the outer wall of the side plate 3, and two sliding columns 29 are fixedly installed on the outer wall of the printing frame 5. Each sliding column 29 is slidably connected to one guide rail 28, and the two sliding columns 29 are slidably engaged with the two guide rails 28. Each sliding column 29 is fixedly connected to the printing frame 5, which makes the printing mechanism more stable when it descends vertically, plays a guiding role, improves the stability of the device, and helps to improve the printing effect.

[0045] Reference Figures 1 to 8As shown, the top of the base plate 1 has two grooves 30 for the four rollers 22 to roll. Each groove 30 allows two rollers 22 to slide on its top, which limits the four rollers 22 and thus limits the two sliders 21. When the output end of the cylinder 17 extends downward, the rotating plate 20 drives the four rollers 22 at the bottom of the two sliders 21 to first descend and contact the grooves 30 and then move away from each other, realizing the transformation of the two rotating plates 20 from a vertical state to a horizontal state. This causes the two pressure rods 6 to move away from each other and flatten the packaging box.
