[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0025] Embodiment one:

[0026] In combination with Figs. 1-2 As shown in the figure, a kind of carton temporary screen printing device, overall structure design compact and complete function, first, the device is equipped with anti-overflow bottom plate 1, the anti-overflow bottom plate 1 has unique cavity structure, carefully placed in its cavity printing screen 2, printing screen 2 as the key component of printing, its material and mesh specification are strictly selected and designed, can accurately control the permeation of ink and the definition of printing pattern, the upper surface of anti-overflow bottom plate 1 side, symmetrically arranged with two groups of rotary table 3, the manufacturing process of rotary table 3 is exquisite, the matching precision between its components is extremely high, rotationally set up rotating part 4 between rotary table 3, rotating part 4 is made of high-strength and wear-resistant material, with outstanding rotation flexibility and stability, can keep good running state at different angle positions, two groups of rotating part 4 are firmly provided with printing assembly 5, the connecting mode of printing assembly 5 and rotating part 4 adopts locking bolt 6, this connecting mode is not only convenient and fast, but also can ensure the installation firmness of printing assembly 5 on rotating part 4, can effectively avoid displacement or loosening phenomenon caused by vibration or other external factors in printing process.

[0027] Further, the detailed structure of the printing assembly 5 is described. The printing assembly 5 includes a printing frame 501 fixedly arranged between the two groups of rotating members 4. The printing frame 501 serves as the main frame of the printing assembly 5. The structural strength of the printing frame 501 is strictly calculated and tested, and can withstand various pressures and stresses generated during printing. The inner walls of the cavity of the printing frame 501 are accurately provided with guide rods 502. The surfaces of the guide rods 502 are finely polished and treated with a special anti-rust coating to ensure that they are smooth and durable. The two groups of guide rods 502 are slidingly provided with sliding blocks 503. The outer diameter of the guide rods 502 and the inner diameter of the sliding blocks 503 are tightly matched to achieve smooth sliding between them. The two groups of sliding blocks 503 are firmly connected with a support bottom rod 504. The support bottom rod 504 plays a key supporting role. A pneumatic cylinder 505 is arranged on the outer side wall of the printing frame 501. The pneumatic cylinder 505 is selected from a type with stable performance and accurate power output. The pneumatic cylinder 505 can accurately extend and retract. The pneumatic cylinder 505 is connected with the support bottom rod 504 through the extension rod. Through this connection mode, the pneumatic cylinder 505 can effectively drive the support bottom rod 504 to move. The support bottom rod 504 is connected with a fixed bottom rod 507 through a group of carefully adjusted springs 506. The spring constant of the spring 506 can avoid damage caused by the subsequent fixed bottom rod 507 running to the end of the cavity of the printing frame 501 during printing. The spring 506 provides just the right amount of cushioning. The fixed bottom rod 507 is connected with a doctor blade 508 through high-strength bolts. The doctor blade 508 has good flexibility and wear resistance. The size of the doctor blade 508 is perfectly matched with the printing screen 2 and the printing area of the carton. The doctor blade 508 can uniformly extrude the ink through the printing screen 2 during printing, so as to form a clear, complete and high-quality printing pattern on the surface of the carton.

[0028] In the embodiment, the corners of the rotating table 3 are provided with arc-shaped transition structures. The arc-shaped transition structures can effectively avoid collisions, scratches and other accidents with surrounding equipment components, operators or cartons due to the sharp shape of the corners, greatly improving the safety and stability of the entire device, and providing a solid foundation for the efficient and stable operation of the temporary screen printing device for cartons.

[0029] In the embodiment, the pneumatic cylinder 505 plays a core role in driving the key actions of the printing assembly. The connecting part of the pneumatic cylinder 505 and the support bottom rod 504 is specially provided with a universal joint 509 to ensure that the power output by the pneumatic cylinder 505 can be accurately and stably transmitted to the support bottom rod 504, without causing jamming or energy loss due to slight changes in the force direction. This not only ensures the smooth operation of the printing assembly 5 in different working states, but also greatly improves the precision and reliability of the entire printing process, so that the device can perform well in various complex printing tasks.

[0030] The spring 506 plays a very key role in this embodiment, and at least 4 are provided and arranged uniformly between the support bottom rod 504 and the fixed bottom rod 507. These springs 506 can always maintain a stable elastic coefficient during long-term and high-frequency use. In terms of layout, the uniform distribution design enables the pressure to be evenly distributed on the entire fixed bottom rod 507, avoiding the tilting of the blade 508 caused by excessive or insufficient local pressure.

[0031] In this embodiment, the length of the blade 508 matches the length of the printing screen 2. The carefully designed length precisely matches the length of the printing screen 2. When the blade 508 moves during printing, it can cover the entire width of the printing screen 2 at one time. This feature enables the ink to penetrate from one end to the other end of the printing screen 2 synchronously and stably under the uniform extrusion of the blade 508 during each printing operation, thereby ensuring the formation of a complete, continuous and uniform printed pattern on the surface of the carton. Whether it is a large-area carton or a small carton with high pattern accuracy requirements, this length-matching design can effectively avoid problems such as uneven ink application, pattern defects or repeated printing caused by insufficient length of the blade 508, greatly improving the printing quality and efficiency, and enabling the device to meet diverse carton printing needs and provide exquisite and consistent printing effects for product packaging.
