Technical Field

[0001] This utility model relates to the field of cardboard printing technology, and specifically to a color box cardboard printing apparatus. Background Technology

[0002] Screen printing equipment is commonly used for printing on cardboard. Its working principle involves transferring ink through the mesh of a screen onto the printing material to form patterns or text. During the printing process, the printing material is typically placed on the machine table, and the screen moves up and down or left and right to evenly transfer the ink onto the material surface.

The equipment base is vertically fixed below the outer shell of the equipment. The printing workbench is installed inside the equipment base and is connected by adhesive. The screw is spirally connected to the bottom of the printing plate. The fixing locking plate is provided with a reserved mounting hole, a support plate, a fixing locking screw, a spring, and a telescopic block.

[0004] The aforementioned cardboard printing plates have the following problems: parallel loading of cardboard is not possible during the printing process, resulting in long equipment waiting times and low production efficiency. Utility Model Content

[0022] The following is a description of the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.

[0023] Example 1

[0024] A color box cardboard printing apparatus includes: a machine base 1, a carrying mechanism 2, and a printing mechanism 3. The carrying mechanism 2 includes a pneumatic slide rail 21, a pneumatic slide rail 22, a carrying platform 23, and a carrying platform 24. The carrying platform 23 is slidably disposed within the pneumatic slide rail 21 and located above the carrying platform 24. The pneumatic slide rail 22 is disposed inside the pneumatic slide rail 21. The carrying platform 24 is slidably disposed on the pneumatic slide rail 22 and its upper surface is higher than the upper surface of the pneumatic slide rail 21. The printing mechanism 3 includes a linear module 31 disposed on the machine base 1, a linear module 32 disposed on the linear module 31, a squeegee module 33 disposed on the linear module 32, and a screen printing module 34 fixedly disposed at the lower end of the linear module 32.

[0025] like Figures 1-4As shown, in actual use, the operator first places a set of cardboard to be printed on the carrier platform 23. Utilizing the sliding connection between the carrier platform 23 and the pneumatic slide rail 21, the pneumatic slide rail 21 drives the carrier platform 23 to move along a preset track directly below the printing mechanism 3. Then, the linear module 31 drives the linear module 32 to move vertically along the machine platform 1, transporting the squeegee module 33 and the screen printing module 34 to a designated position above the carrier platform 23. At this time, the screen printing module 34 is in close contact with the upper surface of the cardboard, ensuring uniform ink transfer during printing. Next, the linear module 32 drives the squeegee module 33 to move horizontally. The squeegee in the squeegee module 33 scrapes the ink across the screen of the screen printing module 34 with constant pressure. Under the pressure of the squeegee, the ink passes through the perforated pattern of the screen and is transferred to the surface of the cardboard, completing one printing operation.

[0026] While printing on the cardboard on carrier platform 23, pneumatic slide rail 22 moves carrier platform 24 to the outside of the device, allowing the operator to place another set of cardboard to be printed on carrier platform 24. After printing on the cardboard on carrier platform 23 is complete, pneumatic slide rail 21 moves carrier platform 23 to the outside of the device, while pneumatic slide rail 22 moves carrier platform 24 to the underside of the printing mechanism 3. Linear module 31 drives linear module 32 to adjust its height, ensuring that the screen printing module 34 adheres to the upper surface of the cardboard on carrier platform 24, initiating a new round of printing. The alternating operation of the two carrier platforms effectively reduces equipment waiting time and improves overall printing efficiency.

[0027] The pneumatic slide rails and the drive system for the support platform are existing technologies and will not be described in detail again.

[0028] As a further preferred embodiment, both the first support platform 23 and the second support platform 24 are provided with vacuum tubes 41 and have a number of adsorption holes 42 on their upper surfaces, and the adsorption holes 42 are connected to the vacuum tubes 41.

[0029] Specifically, during the printing process, negative pressure is generated through vacuum tube 41 and adsorption hole 42 to tightly adsorb the cardboard onto the carrier platform, ensuring that the cardboard is flat and fixed in position, effectively preventing the cardboard from shifting during the printing process, and improving the accuracy and quality of printing.

[0030] As a further preferred embodiment, the doctor blade module 33 includes a sliding seat 331 disposed on the linear module 32, a mounting seat 332 fixedly disposed on the sliding seat 331, and a doctor blade 333 disposed in the mounting seat 332, the lower end of the doctor blade 333 being able to abut against the screen module 34.

[0031] Specifically, during the printing process, the linear module 2 32 drives the sliding seat 331 to reciprocate, thereby scraping the ink.

[0032] As a further preferred embodiment, the wire mesh module 34 includes a mounting bracket 341, an adjusting bolt 342, and a wire mesh plate 343. The mounting bracket 341 is disposed on both sides of the straight module 32 and has a U-shaped cross-section. The threaded portion of the adjusting bolt 342 is threadedly connected to the upper end of the mounting bracket 341. The wire mesh plate 343 is slidably disposed in the mounting bracket 341 and its upper end can abut against the lower end of the adjusting bolt 342.

[0033] Specifically, the screen stencil 343 is slidably mounted inside the mounting bracket 341, with its upper end abutting against the lower end of the adjusting bolt 342, ensuring the stability and contact pressure of the screen stencil 343 during the printing process. By unscrewing the adjusting bolt 342, the screen stencil 343 can be easily placed and removed, adapting to different printing pattern requirements and greatly improving printing efficiency and flexibility.

[0034] As a further preferred embodiment, a circular rubber pad 3421 is provided at the lower end of the adjusting bolt 342, and the circular rubber pad 3421 can abut against the upper end of the wire mesh plate 343.

[0035] Specifically, by adding a buffer layer, the rigid contact between the adjusting bolt 342 and the screen stencil 343 is reduced, avoiding damage to the screen stencil 343. At the same time, the elastic properties of the rubber pad can compensate for minor unevenness of the screen stencil 343, ensuring a tight fit between the screen stencil 343 and the mounting bracket 341, thereby improving the stability of the printing process and the printing quality.

[0036] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
