[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-7 The present invention provides a technical solution as follows:

[0031] An ink vacuum degassing machine includes a body 1 and a tempered glass cover 2. The tempered glass cover 2 is hinged to the top opening of the body 1. A vacuum pump body 3 is provided on one side of the body 1. An annular frame 4 is provided inside the body 1. An annular groove is formed on the inner wall of the annular frame 4. A rotating platform 5 is slidably connected to the inner cavity of the annular groove. A rotating rod is connected to the bottom of the rotating platform 5. A servo motor 6 is connected to one end of the rotating rod and is located inside the body 1. Two placement cylinders 7 are symmetrically arranged on the top of the rotating platform 5. The placement cylinders 7 are for items that need to be processed. The ink cartridge has two retractable inner cavities of placement cylinders 7 equipped with linkage components 8. The other end of the linkage components 8 abuts against a leveling component 9, which is located on the rotating platform 5. This structural design makes the layout of the components inside the machine body 1 reasonable. The rotating platform 5 can achieve stable rotation through the connection of the rotating rod and the servo motor 6, providing a power basis for subsequent processing operations. The cooperation between the annular frame 4 and the annular groove ensures the smooth rotation of the rotating platform 5. The placement cylinders 7 and the internal components facilitate the placement of the ink cartridge and subsequent linkage and leveling operations.

[0032] In this embodiment, the rotating platform 5 is provided with two symmetrically arranged upright plates 51, and each upright plate 51 is provided with a positioning rod 52. The positioning rod 52 is hinged to the adjacent linkage component 8. The symmetrical arrangement of the upright plates 51 and the positioning rod 52 and their hinged connection with the linkage component 8 can provide stable support and rotation center for the linkage component 8, ensuring the accuracy of the motion trajectory and action of the linkage component 8 during operation, and enhancing the stability and reliability of the structure.

[0033] In this embodiment, a placement opening is provided at one end of the placement cylinder 7, and a sliding groove is provided at the bottom of the inner cavity of the placement opening. The linkage component 8 is slidably connected to the inner cavity of the sliding groove, and an arc-shaped channel communicating with the sliding groove is provided at the bottom of the placement cylinder 7. The design of the placement opening and the sliding groove of the placement cylinder 7 facilitates the installation and sliding of the linkage component 8. The existence of the arc-shaped channel at the bottom of the placement cylinder 7 provides a certain space margin for the movement of the linkage component 8, avoids interference during the movement, and ensures that the linkage component 8 can smoothly extend, retract and slide within the placement cylinder 7, thereby improving the overall operating efficiency of the equipment.

[0034] In this embodiment, the linkage component 8 includes a telescopic rod 81, which is slidably connected to the inner cavity of the slide groove. A contact plate 82 is connected to the bottom end of the telescopic rod 81, and the contact plate 82 is located in the inner cavity of the placement cylinder 7. One end of the telescopic rod 81 is hinged to an arc-shaped push rod 83, the cross-section of which is arc-shaped. The other end of the arc-shaped push rod 83 is provided with a roller, which abuts against the leveling component 9. A strip groove that cooperates with the positioning rod 52 is provided on the side wall of the arc-shaped push rod 83. The telescopic rod 81 and the contact plate 82 in the linkage component 8 can accurately sense the weight change of the ink cartridge. The arc-shaped cross-section of the arc-shaped push rod 83 and the roller can convert the weight change into an effective pushing action. The strip groove that cooperates with the positioning rod 52 ensures the standardization of its movement, so that the linkage component 8 can effectively transmit the weight information of the ink cartridge to the leveling component 9 and achieve precise leveling action.

[0035] In this embodiment, the leveling component 9 includes a housing 91. Both sides of the housing 91 have openings for limiting the arc-shaped push rod 83. The top of the housing 91 has two slide rails, and a lifting rod 92 is slidably connected to the inner cavity of the slide rails. One end of the lifting rod 92 is arc-shaped, and the other end of the lifting rod 92 has a flat plate that fits against the roller. The openings on the housing 91 in the leveling component 9 can effectively limit the arc-shaped push rod 83, ensuring the accuracy of its movement direction. The cooperation between the slide rails and the lifting rod 92 allows the lifting rod 92 to reliably slide up and down according to the push of the roller. The arc shape of the lifting rod 92 can better achieve contact with the horizontal plate 94, improving the reliability and accuracy of the leveling action.

[0036] In this embodiment, the leveling assembly 9 also includes a connecting seat 93, one end of which is hinged to a horizontal plate 94. A level 95 is provided on the top of the horizontal plate 94, and both ends of the horizontal plate 94 abut against one end of the lifting rod 92. The design of the connecting seat 93 and the hinged horizontal plate 94 in the leveling assembly 9 facilitates the installation and position adjustment of the level 95. Through the abutment of the lifting rod 92 against the horizontal plate 94, the leveling information caused by the weight difference of the ink cartridge can be clearly reflected on the level 95, allowing the operator to intuitively observe and adjust the weight balance of the ink cartridge, ensuring the stability of the equipment during the processing.

[0037] In this embodiment, the input end of the vacuum pump body 3 is connected to the inner cavity of the machine body 1, and the other side of the vacuum pump body 3 is connected to an exhaust pipe. The connection between the vacuum pump body 3 and the machine body 1 can quickly create a vacuum inside the machine body 1, providing a suitable vacuum environment for the defoaming and other processing of ink. The exhaust pipe facilitates the discharge of the extracted gas, ensuring that the processing is carried out under ideal vacuum conditions, thereby improving the processing effect and product quality.

[0038] Working principle: When in use, first open the tempered glass cover 2 and put the ink box into the corresponding placement tube 7. At this time, the amount of ink in the ink box will affect the weight of the ink box. When the ink box is placed at both ends, the weight of the ink box will press the corresponding contact plate 82.

[0039] The weight of the contact plate 82 will push the telescopic rod 81 to the bottom, and the other end of the arc-shaped push rod 83 will tilt around the center of the positioning rod 52. At this time, the other end of the arc-shaped push rod 83 will drive the roller to contact the flat plate at the bottom of the lifting rod 92 and push the lifting rod 92. When the lifting rod 92 moves to the top, it will contact the horizontal plate 94 and push the horizontal plate 94 to tilt.

[0040] At this time, the personnel visually observe the movement of the bubbles in the level 95 to determine whether the weights of the ink cartridges placed at both ends are the same, so as to avoid the problem of rotational shaking and shaft offset caused by different ink volumes during the debubbling process, thereby improving the stability and service life of the equipment.

[0041] It should be noted that when the bubble in the level 95 is not centered, the ink weight in the two placement cylinders 7 can be equalized by adding an appropriate amount of ink to the ink cartridge.

[0042] At this time, the servo motor 6 is started, and the power output of the servo motor 6 drives the rotating platform 5 to rotate, which, together with the vacuum pump body 3, evacuates the air inside the machine body 1, making the machine body 1 a vacuum.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.

[0044] Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
