Technical Field

[0001] The present application relates to the technical field of chemical packaging, and in particular to an automatic film placing and kneading device for an air barrier film of an ink tank. Background Art

[0002] Due to its special physical properties, ink is generally filled in ink packaging barrels with larger diameters. After filling, a plastic film, namely the ink tank air barrier film, needs to be covered on the ink surface to isolate the ink surface from the air and prevent oxidation and agglomeration of the ink surface. Then the packaging barrel lid is closed.

[0003] In related industries, after the ink filling is completed, manual film removal and manual film covering are adopted. This method has the problems of low work efficiency and high labor intensity. Moreover, since manual film removal requires sampling at a specific position, manual operation requires high skills and experience, which increases the complexity and difficulty of the operation, and also increases the possibility of error. Manual film covering is difficult to align the position of the film, and bubbles are easily formed between the air barrier film and the ink during adjustment. If the bubbles are not completely eliminated, the ink surface will oxidize and agglomerate, which has a great impact on the quality of the ink.

[0004] In view of the above-mentioned related technologies, in order to improve the placement efficiency of the air barrier film, the applicant has designed an automatic film placement and kneading device that automatically removes the air between the air barrier film and the ink. Utility Model Content

By installing multiple vacuum adsorption devices on the pressure plate, the air barrier film is adsorbed flatly on the pressure plate.

After the pressure plate presses the air barrier film, the air between the air barrier film and the ink is driven from the middle to the periphery, initially expelling the air. Then, the pressure plate vibrator vibrates, driving the pressure plate to vibrate.

[0037] The following is combined with Figure 1 -Attached Figure 3 This application is described in further detail.

[0038] The embodiment of the present application discloses an automatic film placing and kneading device for an air barrier film of an ink tank.

[0041] Specifically, the film release assembly 3 includes a connecting plate 31, a flexible connecting member 32, a pressure plate vibrator 34, a pressure plate 33 and a vacuum adsorption device 35. The pressure plate 33 is a circular plate adapted to the contour of the ink tank. The connecting plate 31 and the pressure plate 33 are parallel to each other. The flexible connecting member 32 is provided between the connecting plate 31 and the pressure plate 33 to connect and fix them. Figure 2 The flexible connector 32 is a spring-loaded rod, and the connecting plate 31 and the pressure plate 33 are both fixed to the flexible connector 32 with bolts. The side of the pressure plate 33 away from the connecting plate 31 is provided with a curved surface convex outward from the middle. The curved surface can gradually drive the air between the film and the ink from the middle to the periphery, and then discharge it.

[0042] Four flexible connectors 32 are arranged in a rectangular pattern around the center of the pressure plate 33 to ensure a stable connection. A pressure plate vibrator 34 is bolted to the center of the pressure plate 33 near the flexible connector 32. This vibrator is used to vibrate the ink to fill the gap beneath the membrane, effectively preventing residual gas.

[0043] The vacuum adsorption device 35 includes a vacuum suction cup 351 and a quick-connect pipe section 352. The vacuum suction cup 351 is inserted and fixed at one end of the quick-connect pipe section 352 and the two are connected; the quick-connect pipe section 352 passes through the pressure plate 33 and is fixed on the pressure plate 33. The vacuum suction cup 351 is arranged on the side of the pressure plate 33 away from the connecting plate 31. The vacuum suction cup 351 has good sealing performance after contacting the membrane, which helps to improve the stability of membrane adsorption.

[0044] refer to Figure 3The quick-connect pipe section 352 is provided with a flange 353 on the end close to the vacuum suction cup 351, and a positioning groove 331 is provided on the side wall of the pressure plate 33 corresponding to the flange 353, and the flange 353 is installed in the positioning groove 331; the quick-connect pipe section 352 is provided with an air circuit quick interface 355 on the end away from the vacuum suction cup 351, and a threaded connection section 354 is provided on the pipe body of the quick-connect pipe section 352 between the air circuit quick interface 355 and the pressure plate 33, and a fixing nut 356 is screwed on the threaded connection section 354 to abut against the pressure plate 33.

[0045] Specifically, the height adjustment assembly 4 includes a first fixing plate 42, a second fixing plate 43, and a cylinder 41. The first fixing plate 42 is bolted to the upper end of the frame 1. The cylinder 41 is a dual-axis cylinder, with its movable axis facing downward. The upper end of the cylinder 41 is bolted to the first fixing plate 42, while the lower end of the cylinder 41 is bolted to the second fixing plate 43. The second fixing plate 43 is bolted to the connecting plate 31. The extension and retraction of the cylinder 41 controls the overall elevation of the film unwinding assembly 3.

[0046] The bottom of the frame 1 is provided with supporting legs 6, and the frame 1 is fixedly connected to the supporting legs 6 with bolts. The supporting legs 6 include adjustable bolts for supporting and stabilizing the frame 1 to adapt to uneven ground and ensure that the frame 1 is level and stable.

[0047] The working process of Example 1 of the present application is as follows: when the equipment starts working, the ink tank is manually placed on the placement platform 2 and pressed against the two side plates of the V-shaped positioning plate 22. The ink tank is quickly positioned by the V-shaped positioning plate 22 so that the pressure plate 33 is aligned with the ink tank. The air barrier film is attached to the bottom of the pressure plate 33, and the air circuit of the vacuum suction cup 351 is controlled to evacuate the air, so that the four vacuum suction cups 351 adsorb and fix the air barrier film; then the cylinder 41 is controlled to lower the pressure plate 33 along the axis of the cylinder 41; when the pressure plate 33 lowers with the air barrier film and presses on the ink, the vacuum suction cup 351 discharges the air and places the air barrier film in the ink tank. Since the pressure plate 33 is a plate with a curved surface on the bottom and a thick middle and thin sides, the pressure plate 33 drives the air between the film and the ink from the middle to the periphery and then discharges it. The platen vibrator 34 above the platen 33 vibrates the platen 33. Simultaneously, the platform vibrator 23 below the vibrating platform 21 vibrates the platform 21. The vibrations of the platen 33 and platform 21 cause the ink to fill the gap beneath the membrane, effectively preventing residual gas. The air cylinder 41 is then controlled to move, raising the membrane assembly 3.

[0048] The working principle of Example 1 of the present application is as follows: a cylinder 41 is used to drive the raising and lowering of the film-releasing assembly 3 for automatic film release. By providing multiple vacuum suction cups 351 on the pressure plate 33, the air barrier film disc is smoothly adsorbed on the pressure plate 33. The pressure plate 33 is lowered to place the air barrier film smoothly and efficiently into the ink tank. This effectively improves the placement efficiency of the air barrier film, and the reduction of wrinkles in the air barrier film also helps to expel the air between the air barrier film and the ink. Furthermore, the ink is vibrated by the vibration platform 21 and the pressure plate 33, so that the gas in the ink is fully discharged, ensuring the function of the air barrier film. The pressure of the pressure plate 33 can be uniformly controlled by air pressure. The automatic film-releasing and kneading device for the air barrier film of the ink tank disclosed in the present application is convenient to use and more efficient in film release.

[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
