Detailed Implementation

[0027] The present invention will now be described in conjunction with specific embodiments.

[0028] Example 1, as Figure 1 , Figure 3 as well as Figure 4 As shown, a new type of curved surface printing machine includes a frame 1 and a transfer wheel 2 rotatably mounted on the frame 1. The outer contour surface of the transfer wheel 2 is equipped with a font template 21.

[0029] Among them, such as Figure 1 , Figure 3 as well as Figure 4 As shown, a roller 3 is rotatably mounted on the frame 1 below the transfer roller 2. The roller 3 is a rubber roller structure.

[0030] Furthermore, the new curved surface printing machine also includes a vibratory feeder 4, a receiving tray 5, and a printing guide rail 6 respectively installed on the frame 1. The printing guide rail 6 has a material groove 61 for the workpiece to pass through, and the material groove 61 of the printing guide rail 6 is connected to the discharge port of the vibratory feeder 4.

[0031] Furthermore, the receiving tray 5 is located below the printing roller 3, the lower end of the printing guide rail 6 is located between the receiving tray 5 and the printing roller 3, and the lower end of the material groove 61 of the printing roller 3 is arc-shaped.

[0032] When the novel curved surface printing machine of this embodiment is working, the round tube workpiece is placed into the vibratory feeder 4. The round tube workpiece can be a round tube component, such as a discharge tube. The vibratory feeder 4 feeds the workpiece out in an orderly manner, and the workpiece fed out by the vibratory feeder 4 enters the material groove 61 of the roller printing guide 6 in sequence. The workpiece moves downward along the material groove 61 and enters the arc section of the material groove 61.

[0033] When printing on a workpiece using the novel curved surface printing machine of this embodiment, the transfer roller 2 and the roller 3 rotate synchronously in opposite directions under the drive of the corresponding power device. After ink is transferred to the font template 21 of the transfer roller 2, the transfer roller 2, which rotates synchronously in opposite directions with the roller 3, transfers the ink at the position of the font template 21 to the roller 3. Since the roller 3 is a rubber wheel structure, when the roller 3 rotates, the workpiece falling into the arc section of the material groove 61 rolls and contacts the roller 3, and the workpiece rotates with the roller 3. During this process, the ink on the roller 3 is rolled onto the surface of the workpiece, thereby realizing the workpiece printing operation. In the process of the workpiece rotating with the roller 3, the workpiece rolls along the material groove 61 and finally falls into the receiving tray 5, thereby realizing the automatic unloading and collection of the workpiece after the text is printed.

[0034] It should be emphasized that the new curved surface printing machine in this embodiment realizes automatic workpiece feeding through the vibratory feeder 4 and the roller printing guide rail 6, and automatically receives the workpiece after the roller printing text through the receiving tray 5 located below the roller printing guide rail 6, and realizes automatic unloading and storage.

[0035] In summary, the novel curved surface printing machine of this embodiment has the advantages of novel structural design, high degree of automation and high working efficiency through the above structural design.

[0036] Example 2, as Figures 1 to 4As shown, the difference between this embodiment 2 and embodiment 1 is that: the frame 1 includes a base 11 and a lifting mounting frame 12 mounted on the base 11, and a lifting movable seat 13 is slidably mounted on the lifting mounting frame 12; a lifting drive assembly 14 is mounted on the upper end of the lifting mounting frame 12, and the lifting drive assembly 14 is drivenly connected to the lifting movable seat 13.

[0037] The lifting seat 13 is equipped with a scraper roller 71, a roller 8, and a scraper mechanism 72 located next to the scraper roller 71. The transfer roller 2 and the roller 3 are rotatably mounted on the lifting seat 13.

[0038] Furthermore, the lifting movable seat 13 is equipped with a drive motor 91, and the power output shaft of the drive motor 91 is connected to the doctor blade 71, the ink roller 8, the transfer roller 2, and the printing roller 3 respectively through the synchronous belt transmission mechanism 92.

[0039] In addition, the lifting mounting frame 12 includes two spaced-apart optical axes 121 that extend vertically respectively, and the lower ends of each optical axis 121 are fastened to the base 11 respectively; the lifting movable seat 13 is screwed with guide sleeves 15 corresponding to each optical axis 121, and each guide sleeve 15 cooperates with the corresponding optical axis 121; the upper end of the lifting mounting frame 12 is provided with a top block 122 that is connected to the upper ends of the two optical axes 121, and the lifting drive assembly 14 is installed on the top block 122.

[0040] Specifically, the lifting drive assembly 14 includes a lifting drive screw 141 that is rotatably mounted on the top block 122 and arranged vertically. The lifting movable seat 13 is screwed with a lifting screw nut 142 corresponding to the lifting drive screw 141. The lifting screw nut 142 cooperates with the lifting drive screw 141 and together form a ball screw pair.

[0041] During the process of adjusting the height of the movable seat 13 using the lifting drive assembly 14, the operator manually rotates the lifting drive screw 141. The rotating lifting drive screw 141 drives the lifting screw nut 142 to move up and down. The moving lifting screw nut 142 then drives the movable seat 13 to move up and down synchronously to achieve height adjustment.

[0042] It should be explained that in this embodiment, the roller printing guide rail 6 is directly installed on the lifting movable seat 13. During operation, the operator can drive the lifting movable seat 13 to move the cabinet up and down through the lifting drive component 14, and then drive the roller printing guide rail 6 to move up and down synchronously through the lifting movable seat 13, so that the height position of the feed port of the roller printing guide rail 6 is adapted to the height position of the discharge port of the vibratory feeder 4.

[0043] Furthermore, in the operation of the new curved surface printing machine in this embodiment 2, the drive motor 91 drives the squeegee 71, the ink roller 8, the transfer roller 2, and the printing roller 3 to rotate through the synchronous belt transmission mechanism 92. During this process, the squeegee mechanism 72 scrapes the ink on the squeegee 71 to make the ink on the squeegee 71 even. The squeegee 71 transfers the ink to the ink roller 8, and the ink roller 8 rolls the ink thin through multiple roller structures. The ink thinned by the ink roller 8 is transferred to the font template 21 of the transfer roller 2, and then the font template 21 of the transfer roller transfers the ink to the printing roller 3. The printing roller 3 rolls the ink onto the surface of the workpiece to realize the printing operation on the surface of the workpiece.

[0044] Example 3, as Figure 2 As shown, the difference between this embodiment 3 and embodiment 2 is that the ink scraping mechanism 72 includes an ink scraping mounting base 721 that is fastened to the lifting movable base 13, an ink scraping movable block 722 that is slidably mounted on the ink scraping mounting base 721, and an ink scraping movable block 722 that is equipped with an ink scraping blade 723 that contacts the ink scraping wheel 71.

[0045] Among them, a spring 724 is installed between the ink scraping movable block 722 and the ink scraping mounting base 721 to elastically push the ink scraping movable block 722 toward the ink scraping wheel 71.

[0046] It should be noted that under the elastic force of the spring 724, the doctor blade 722 moves toward the doctor blade 71, thereby causing the doctor blade 723 to elastically contact the surface of the doctor blade 71, so as to ensure that the doctor blade 723 can perform the doctoring operation stably and reliably.

[0047] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
