[0028] The transfer mechanism 7 is provided with a connecting seat 72, and the outer side of the connecting seat 72 is provided with a printing material scraping mechanism 8 for scraping and collecting excess printing material.

[0029] The printing material scraping mechanism 8 is provided with an adjusting assembly 81 and a scraping assembly 82, the adjusting assembly 81 is arranged on the outer side of the connecting seat 72, and the scraping assembly 82 is arranged in the adjusting assembly 81.

[0030] The adjusting assembly 81 comprises a first connecting frame 811 arranged outside the connecting seat 72, the outer side of the first connecting frame 811 is provided with a second mounting frame 812, the second mounting frame 812 is rotatably provided with a connecting plate 813, and the connecting plate 813 movably provided with a scraping roller 825 for scraping and collecting printing material.

[0031] Further, the outer side of the connecting plate 813 is provided with a mounting plate 814, the outer side of the mounting plate 814 is provided with a mounting block 816, and the first spring 815 is arranged between the mounting block 816 and the first connecting frame 811. Through the elastic effect of the first spring 815, the scraping roller 825 can be tightly attached to the surface of the transfer roller 76, improving the efficiency of scraping excess ink and ensuring the uniformity of scraping.

[0032] Further, the first spring 815 is provided with a damper body 817 for slowing down the rotation speed of the connecting plate 813, avoiding vibration caused by rapid rotation and prolonging the service life of the equipment.

[0033] Further, the scraping assembly 82 further comprises a second connecting frame 821 arranged on the outer side of the connecting plate 813 and away from the mounting plate 814, a connecting rod 822 is slidingly arranged in the connecting plate 813, the connecting rod 822 is provided with an abutting block 823 on the side close to the second connecting frame 821, a second spring 824 is arranged outside the connecting rod 822, and a mounting pipe 826 is arranged in the scraping roller 825. The scraping roller 825 can be disassembled and reinstalled, which facilitates regular cleaning and maintenance of the scraping roller 825 and ensures continuous and efficient operation of the equipment.

[0034] Further, the two ends of the second spring 824 are connected with the outer wall of the connecting plate 813 and the abutting block 823 respectively, and the mounting pipe 826 is provided with a groove for abutting and mounting the mounting pipe 826, which ensures the stable installation of the scraping roller.

[0035] Embodiment two: please refer to Figures 1-3 Further, the transfer mechanism 7 is further provided with an integrated table 71, the integrated table 71 is arranged at the top end of the support seat 5, the connecting seat 72 is arranged at the top end of the integrated table 71, the outer side of the connecting seat 72 is provided with a first mounting frame 73, the first mounting frame 73 is movably provided with an ink roller 74, the top end of the integrated table 71 is further provided with a feeding device 75 for supplementing ink to the ink roller 74, the top end of the integrated table 71 is provided with a transfer roller 76 for transferring the egg box 11, and the outer sides of the transfer roller 76 and the ink roller 74 are provided with a synchronous wheel 77 for synchronous rotation of the transfer roller 76 and the ink roller 74. Automatic ink replenishment ensures the continuity of transfer, synchronous rotation ensures the uniformity and consistency of transfer, improves the transfer efficiency and quality.

[0036] Further, the outer wall of the ink roller 74 is in contact with the outer wall of the transfer roller 76, and the outer wall of the transfer roller 76 away from the ink roller 74 is attached to the outer wall of the egg box 11. Through the direct contact mode, the ink can be fully attached to the transfer roller 76 and uniformly transferred to the surface of the egg box 11, realizing high-quality transfer effect.

[0037] In actual operation, first, the egg box 11 to be transferred is placed on the conveying device 3, and the conveying device 3 is started by operating the control device 6. Then, the limiting roller 4 limits the egg box 11 to ensure the stability of the position of the egg box during the transfer process.

[0038] Then, the transfer roller 76 is operated by the control device 6 to transfer the surface of the egg box 11 in transmission. Under the continuous rotation of the transfer roller 76 and the synchronous transmission of the synchronous wheel 77, the ink roller 74 rotates synchronously to ensure that the ink can be continuously attached to the surface of the transfer roller 76, thereby ensuring the transfer effect.

[0039] After the transfer is completed, the transfer roller 76 continues to rotate. Under the action of the first spring 815 and the damper body 817, the connecting plate 813 rotates in the second mounting frame 812, so that the scraping roller 825 tightly abuts against the surface of the transfer roller 76, and the excess ink is scraped off. This step prevents the problem that the surface of the transfer roller 76 has too much ink, which leads to an undesirable subsequent transfer effect.

[0040] When it is necessary to disassemble and clean the scraping roller 825, the connecting rod 822 can be pulled to make the abutting block 823 slide and lose the abutment with the slot in the mounting pipe 826, and then the scraping roller 825 is removed for ink recycling treatment. After cleaning, the scraping roller 825 is reinstalled into the second connecting frame 821, the connecting rod 822 is loosened, and under the action of the second spring 824, the abutting block 823 returns to the initial position and abuts against the inside of the mounting pipe 826 again, thereby completing the assembly of the scraping roller 825.

[0041] The above embodiments only express one or several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
