Description

Technical Field

[0001] This application relates to the field of packaging and printing technology, specifically to an outer packaging printing device. Background Technology

[0002] Packaging printing is one of the core technologies in the commodity circulation process. Its core function is to transfer graphic information to the surface of the substrate in batches through mechanical devices in order to achieve product identification, brand promotion and anti-counterfeiting functions.

[0003] An existing patent (publication number: CN217863273U) discloses a packaging pattern printing device, relating to the field of printing equipment technology. It includes a printing roller, an ink tank, a pressure roller, a discharge roller, and a take-up roller. The printing roller is rotatably positioned above the ink tank. A sponge block is fixedly installed inside the ink tank, abutting against the printing roller. A capillary tube or loose cotton strip is fixedly installed below the sponge block, with its upper end inserted into the sponge block and its lower end extending to the bottom of the ink tank. The pressure roller is rotatably positioned to the left of the printing roller, laterally pressing against it. The discharge roller is rotatably positioned below the pressure roller, and the take-up roller is rotatably positioned to the left of the pressure roller. This invention utilizes the capillary action of the capillary tube or loose cotton strip to evenly conduct ink to the sponge block and coat it onto the printing roller, reducing ink smearing, eliminating the need for an ink roller structure, increasing the effective volume of the ink tank, and reducing the use of a drive device.

[0004] While the device in the aforementioned comparative document simplifies the inking process, it cannot flexibly adjust the gap between the printing roller and the pressure roller, resulting in an inability to meet the printing needs of substrates with different thicknesses. To solve the above problems, an outer packaging printing device is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an outer packaging printing apparatus that can flexibly adjust the distance between the printing roller and the pressure roller to meet the printing needs of substrates with different thicknesses.

[0006] To achieve the above objectives, this application provides the following technical solution: an outer packaging printing device, comprising a base plate, a printing component, and an elastic component. The printing component includes a printing box and two first grooves formed on the upper surface of the base plate. A printing roller is mounted on the upper surface of the printing box, and a sponge block is provided on the bottom surface of the printing roller. Multiple capillary channels are provided at the bottom end of the sponge block, and the bottom ends of the multiple capillary channels are all located inside the printing box. L-shaped plates are fixedly connected to both sides of the outer surface of the printing box. Two L-shaped plates are slidably fitted onto the inner walls of the two first grooves. A lead screw and a guide rod are respectively installed on the inner walls of the two first grooves. The bottom end of one of the two L-shaped plates is threadedly connected to the lead screw. The elastic component includes a reserved groove formed on the surface of the base plate, and a movable guide roller is installed inside the reserved groove.

[0007] Through the above scheme, in the printing assembly, the printing roller in the printing box is evenly inked through the sponge block and capillary tube. The L-shaped plate cooperates with the first slide groove, and the horizontal position of the printing roller can be adjusted when the lead screw rotates. It can be matched with the pressure roller to adapt to substrates of different thicknesses. In the elastic assembly, the elastic adjustment of the guide roller achieves the effect of dynamic pressure compensation, avoiding wrinkles or ghosting. This device solves the problems of poor printing adaptability and low adjustment efficiency of the existing technology while simplifying the mechanical layout, and comprehensively improves printing accuracy and compatibility.

[0008] Furthermore, the guide rod is fixedly connected to the inner wall of the corresponding first slide groove, the lead screw is rotatably sleeved in the inner wall of the corresponding first slide groove, a servo motor is fixedly connected to one side of the base plate, and the output shaft end of the servo motor is fixedly connected to the rotating shaft end of the lead screw.

[0009] The above solution allows the servo motor to easily drive the lead screw to rotate. When the lead screw rotates, the position of the printing roller can be stably adjusted, thus meeting the printing needs of substrates with different thicknesses and making it more practical.

[0010] Furthermore, an unwinding assembly and a pressure roller are installed on the upper surface of the base plate, the printing roller is adapted to the pressure roller, and a winding assembly is installed on the bottom surface of the base plate.

[0011] The above solution, through the coordinated operation of the base plate, unwinding assembly, pressure roller, and rewinding assembly, enables convenient and high-quality printing on the substrate.

[0012] Furthermore, a controller is fixedly connected to the outer surface of the printing box, and the electrical components inside the printing assembly and the winding assembly are all electrically connected to the controller.

[0013] The above solution allows for convenient control of the electrical components inside the printing and winding components by setting up a controller, simplifying the operation process.

[0014] Furthermore, a second sliding groove is provided on both sides of the inner wall of the reserved groove, and the two ends of the guide roller are respectively slidably sleeved on the inner walls of the two second sliding grooves.

[0015] The above scheme allows the guide roller to move within the pre-reserved groove by creating a second chute, which facilitates smooth transport of the printing substrate.

[0016] Furthermore, each of the second chutes has a limit rod installed on its inner wall, and the two ends of the guide roller are respectively slidably sleeved on the outer surfaces of the two limit rods.

[0017] The above scheme allows the guide roller to move more smoothly in the second chute by setting a limiting rod, which facilitates the stable adjustment of the guide roller's position.

[0018] Furthermore, each of the limiting rods is fitted with a telescopic spring on its outer surface, and the two ends of the telescopic spring are respectively fixedly connected to the outer surface of the inner wall guide roller of the second slide groove.

[0019] The above solution allows for flexible adjustment of the guide roller's position using a telescopic spring, thus adapting to the printing needs of substrates with different thicknesses and improving printing quality.

[0020] Furthermore, support columns are fixedly connected to the four corners of the bottom surface of the base plate, and an anti-slip pad is fixedly connected to the bottom end of each support column.

[0021] The above solution, with its supporting columns and anti-slip pads, improves the stability of the device, allowing it to be placed stably on the contact surface.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This packaging printing device integrates an unwinding assembly, a pressure roller, and a rewinding assembly on its base plate, forming a continuous printing path. In the printing assembly, the printing roller inside the printing chamber is evenly inked through a sponge block and capillary tube. An L-shaped plate cooperates with a first slide groove, and a servo motor drives a lead screw and guide rod to adjust the position of the printing roller, which is matched with the pressure roller to accommodate substrates of different thicknesses. In the elastic assembly, the guide roller slides through a second slide groove, and a limit rod is linked with a telescopic spring to dynamically compensate for the pressure between the pressure roller and the printing roller, avoiding wrinkles or ghosting. The controller coordinates various electrical components to simplify the operation process. The anti-slip design at the bottom of the support column enhances stability. This device solves the problems of poor printing adaptability and low adjustment efficiency of existing technologies while simplifying the mechanical layout, comprehensively improving printing accuracy and compatibility.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 , Figure 2 and Figure 4 This embodiment of an outer packaging printing device includes a base plate 1, a printing component 4, and an elastic component 5. The printing component 4 includes a printing box 401 and two first grooves 406 formed on the upper surface of the base plate 1. A printing roller 402 is installed on the upper surface of the printing box 401. A sponge block 403 is provided on the bottom surface of the printing roller 402. A plurality of capillary channels 404 are provided at the bottom end of the sponge block 403. The bottom ends of the plurality of capillary channels 404 are all located inside the printing box 401. By setting the synergistic effect of the sponge block 403 and the capillary channels 404, the printing roller 402 can uniformly print on the substrate.

[0033] Please see Figure 1 , Figure 2 and Figure 4Two L-shaped plates 405 are fixedly connected to both sides of the outer surface of the printing box 401. The two L-shaped plates 405 are slidably fitted onto the inner walls of two first sliding grooves 406. A lead screw 407 and a guide rod 408 are respectively installed on the inner walls of the two first sliding grooves 406. The bottom end of one of the L-shaped plates 405 is threadedly connected to the lead screw 407. The guide rod 408 is fixedly connected to the inner wall of the corresponding first sliding groove 406. The lead screw 407 is rotatably fitted onto the inner wall of the corresponding first sliding groove 406. A servo motor 409 is fixedly connected to one side of plate 1. The output shaft of the servo motor 409 is fixedly connected to the rotating shaft of the lead screw 407. The servo motor 409 can easily drive the lead screw 407 to rotate. When the lead screw 407 rotates, the corresponding L-shaped plate 405 can move in the corresponding first slide groove 406, thereby stabilizing the lateral position of the printing box 401 and the printing roller 402, so as to meet the printing needs of substrates of different thicknesses and make it more practical.

[0034] Please see Figure 2 , Figure 3 and Figure 5 The upper surface of the base plate 1 is equipped with an unwinding assembly 2 and a pressure roller 3. The printing roller 402 is adapted to the pressure roller 3. The bottom surface of the base plate 1 is equipped with a winding assembly 6. Through the cooperation of the base plate 1, the unwinding assembly 2, the pressure roller 3 and the winding assembly 6, a continuous printing path can be formed, facilitating high-quality printing on the substrate. The elastic component 5 includes a reserved groove 501 opened on the surface of the base plate 1. A movable guide roller 503 is installed inside the reserved groove 501. Second sliding grooves 502 are opened on both sides of the inner wall of the reserved groove 501. The two ends of the guide roller 503 are slidably sleeved on the inner walls of the two second sliding grooves 502 respectively. The second sliding grooves 502 allow the guide roller 503 to move inside the reserved groove 501. The movement of the guide roller 503 facilitates smooth transport of the printing substrate. Each second chute 502 has a limit rod 504 installed on its inner wall. The two ends of the guide roller 503 are slidably sleeved on the outer surfaces of the two limit rods 504. The limit rods 504 allow the guide roller 503 to move more smoothly in the second chute 502, facilitating stable adjustment of the guide roller 503's position. Each limit rod 504 has a telescopic spring 505 sleeved on its outer surface. The two ends of the telescopic spring 505 are fixedly connected to the outer surface of the guide roller 503 on the inner wall of the second chute 502. The telescopic spring 505 allows for elastic adjustment of the guide roller 503's position, thus adapting to the printing needs of substrates of different thicknesses and improving printing quality.

[0035] Please see Figure 1 , Figure 2 and Figure 3A controller 7 is fixedly connected to the outer surface of the printing box 401. The electrical components inside the printing assembly 4 and the winding assembly 6 are all electrically connected to the controller 7. By setting the controller 7, the electrical components inside the printing assembly 4 and the winding assembly 6 can be easily controlled to operate, simplifying the operation process. Support columns 8 are fixedly connected to the four corners of the bottom surface of the base plate 1. Anti-slip pads are fixedly connected to the bottom end of each support column 8. The support columns 8 and anti-slip pads can improve the stability of the device, allowing the device to be placed stably on the contact surface.

[0036] In this embodiment, an outer packaging printing device integrates an unwinding assembly 2, a pressure roller 3, and a rewinding assembly 6 on a base plate 1 to form a continuous printing path. In the printing assembly 4, the printing roller 402 in the printing box 401 is evenly inked through a sponge block 403 and a capillary tube 404. An L-shaped plate 405 cooperates with a first slide groove 406. A servo motor 409 drives a lead screw 407 and a guide rod 408 to adjust the position of the printing roller 402, which is matched with the pressure roller 3 to accommodate substrates of different thicknesses. In the elastic assembly 5, the guide roller 503 slides through a second slide groove 502. A limiting rod 504 is linked with a telescopic spring 505 to dynamically compensate for the pressure between the pressure roller 3 and the printing roller 402, avoiding wrinkles or ghosting. A controller 7 coordinates various electrical components to simplify the operation process. The anti-slip design at the bottom of the support column 8 enhances stability. This device solves the problems of poor printing adaptability and low adjustment efficiency in existing technologies by simplifying the mechanical layout, thereby comprehensively improving printing accuracy and compatibility.

[0037] The working principle of the above embodiment is as follows: After the substrate is output from the unwinding assembly 2, it enters the printing area through the gap between the pressure roller 3 and the printing assembly 4. The printing roller 402 absorbs ink through the sponge block 403, and achieves uniform ink penetration to the surface with the help of the capillary tube 404. When the thickness of the substrate changes, the servo motor 409 drives the lead screw 407 to rotate, which drives the L-shaped plate 405 to move laterally along the guide rod 408 in the first slide groove 406, accurately adjusting the gap between the printing roller 402 and the pressure roller 3 to adapt to paper, film or cardboard of different thicknesses. During the printing process, the guide of the elastic component 5... Roller 503 slides through the second slide groove 502. The limit rods 504 on both sides and the telescopic spring 505 work together to dynamically compensate the contact pressure of the pressure roller 3 on the substrate, avoiding wrinkles or printing ghosting caused by sudden changes in material thickness. The controller 7 adjusts the operating parameters of the internal components of the printing component 4 and the winding component 6 in real time to ensure the stability of the registration accuracy. After printing, the ink is transferred to the surface of the substrate by the printing roller 402. The winding component 6 winds up the finished product at a uniform speed. The anti-slip pad at the bottom of the support column 8 effectively suppresses equipment vibration. While simplifying the mechanical structure, it achieves efficient and high-precision printing on substrates of various thicknesses and materials.
