Description

Technical Field

[0001] The present application relates to the technical field of chemical packaging, and in particular to a film 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 the related industry, most air barrier films are applied manually, with workers manually patting the film to expel the air between the film and the ink. This method is inefficient, and if the bubbles are not completely expelled, the ink surface will oxidize and clump, significantly affecting the ink quality.

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

[0005] In order to more thoroughly remove the bubbles between the ink and the air barrier film, the present application provides a film kneading device for the air barrier film of an ink tank.

[0006] The present application provides a film kneading device for an ink tank air barrier film, which adopts the following technical solution:

[0007] A film kneading device for an ink tank air barrier film includes a frame, a placement platform, a height adjustment component and a pressing component. The placement platform is fixedly connected to the bottom of the frame, the pressing component is suspended above the placement platform, and the height adjustment component is used to fix and adjust the height of the pressing component; the pressing component includes a connecting plate, a flexible connecting piece, a pressing plate and a vibrator, and the connecting plate and the pressing plate are connected by a flexible connecting piece; the vibrator is fixedly connected to the side of the pressing plate close to the connecting plate.

[0008] By adopting the above technical solution, the height adjustment component controls the pressing component to descend and press into the ink tank below. When the pressure plate presses the air barrier membrane, the air between the air barrier membrane and the ink will be driven from the middle to the periphery, and the air will be initially discharged. The vibration of the vibrator drives the pressure plate to vibrate, and the ink is filled in the gap between the air barrier membrane and the ink through the vibration of the pressure plate, thereby fully discharging the air. The flexible connector only serves to suspend the pressure plate and will not affect the vibration of the pressure plate.

[0009] Preferably, the side of the pressing plate away from the connecting plate is configured as an arc-shaped surface convex outward in the middle.

[0010] By adopting the above technical solution, when the pressure plate presses the air barrier film, the protruding part in the middle of the pressure plate first contacts the air barrier film. In the process of pressing the air barrier film, the air between the air barrier film and the ink will gradually be driven from the middle to the periphery, which is more conducive to the discharge of air.

[0011] Preferably, four flexible connectors are provided, and the flexible connectors are distributed in a rectangular shape with the center of the pressing plate as the center; the vibrator is located in the center of the pressing plate.

[0012] By adopting this technical solution, the flexible connector absorbs shock and vibration, reducing vibration and noise in the film kneading device, and improving its operational stability and reliability. When the vibrator is operating, the vibration energy generated is absorbed by the flexible connector, reducing the impact on surrounding structures and protecting the film kneading device from damage. The vibrator is located in the center of the pressure plate, ensuring that the vibration energy is evenly distributed. The combined design of the flexible connector and the central vibrator improves the stability and reliability of the film kneading device by optimizing force transmission and vibration control.

[0016] By adopting the above technical solution, the internal threaded sleeve is fixed on the second fixed plate, the height adjustment screw is threadedly matched with the internal threaded sleeve, and the height adjustment screw can be controlled to move in an axial straight line by rotating the height adjustment screw.

[0017] Preferably, the connecting structure includes a first fixed plate, a third fixed plate and a connecting column, the connecting column vertically passes through the second fixed plate and slides with the second fixed plate; the first fixed plate is arranged at the upper end of the connecting column, and the first fixed plate is fixedly connected to the upper end of the connecting column; the third fixed plate is arranged at the lower end of the connecting column, and the third fixed plate is fixedly connected to the lower end of the connecting column; the height adjustment screw passes through the first fixed plate, and the height adjustment screw is rotatably connected to the first fixed plate; the clamping assembly is installed on the third fixed plate.

[0018] By adopting the above technical solution, the height-adjusting screw is rotatably connected to the first fixed plate, thereby driving the first fixed plate to rise and fall; the connecting column is fixed to the first fixed plate and slidingly cooperates with the second fixed plate, so that the first fixed plate can only follow the height-adjusting screw to adjust the height without following the rotation; the third fixed plate is fixed at the lower end of the connecting column for installing the clamping assembly, thereby driving the clamping assembly to rise and fall through the third fixed plate.

[0019] Preferably, a sliding sleeve is installed on the second fixing plate and is in sliding engagement with the connecting column.

[0020] By adopting the above technical solution, the sliding sleeve is provided to reduce the sliding resistance and wear of the connecting column, and the lifting and lowering of the connecting structure is more stable.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The height adjustment assembly controls the pressing assembly to descend and press into the ink tank below. When the pressing plate presses the air barrier membrane, the air between the air barrier membrane and the ink is driven from the middle to the periphery, initially expelling the air. The vibration of the vibrator drives the pressing plate to vibrate, and the vibration of the pressing plate causes the ink to fill the gap between the air barrier membrane and the ink, thereby fully expelling the air. The flexible connector only serves to suspend the pressing plate and will not affect its vibration.

[0029] 2. The flexible connector absorbs shock and vibration, reducing vibration and noise in the film kneading device and improving its operational stability and reliability.

[0035] The following is combined with Figure 1 -Attached Figure 3 This application is described in further detail.

[0036] The embodiment of the present application discloses a film kneading device for an air barrier film of an ink tank.

[0037] Example 1

[0038] Reference Figure 1A film kneading device for an ink tank air barrier film includes a frame 1, a placement platform 2, a pressing component 3 and a height adjustment component 4. The placement platform 2 is a horizontal plate fixed to the bottom of the frame 1, and the placement platform 2 is used to place the ink tank; the pressing component 3 is used to press on the ink tank air barrier film to discharge the air between the ink tank air barrier film and the ink; the height adjustment component 4 is installed on the top of the frame 1, and the height adjustment component 4 is used to adjust the height of the pressing component 3.

[0039] Specifically, the pressing assembly 3 includes a connecting plate 31, a flexible connector 32, a pressing plate 33, and a vibrator 34. The pressing plate 33 is a circular plate adapted to the contour of the ink tank. The connecting plate 31 and the pressing plate 33 are parallel to each other. The flexible connector 32 is provided between the connecting plate 31 and the pressing plate 33 to connect and fix them. Figure 2 The connecting plate 31 and the pressure plate 33 are both secured with screws and flexible connectors 32. Four flexible connectors 32 are arranged in a rectangular pattern centered on the center of the pressure plate 33 to achieve a stable connection. The upper end of the pressure plate 33 is flat, while the lower end is curved. The pressure plate 33 is thick in the middle and thin at the sides, which is used to expel air from the center of the membrane to the periphery. A vibrator 34 is bolted to the center of the pressure plate 33. The vibrator 34 is used to vibrate the ink to fill the gap below the membrane, effectively preventing residual gas. The flexible connector 32 is a spring-loaded rod that allows the pressure plate to vibrate smoothly.

[0040] Specifically, the height adjustment assembly 4 includes a manual rotating structure 41 and a connecting structure 42. The connecting structure 42 is fixedly connected to the frame 1. The upper end of the frame 1 is provided with a second fixing plate 5, which is fixedly connected to the upper end of the frame 1. The manual rotating structure 41 is mounted on the second fixing plate 5. The manual rotating structure 41 adjusts its own height by rotating. The connecting structure 42 connects the manual screwing structure 41 and the connecting plate 31 of the pressing assembly 3.

[0041] The manual rotation mechanism 41 includes a height adjustment screw 411 and an internally threaded sleeve 412. The internally threaded sleeve 412 is bolted to the second fixing plate 5. The height adjustment screw 411 passes through the second fixing plate 5 and is threadedly engaged with the internally threaded sleeve 412. An operating handle 413 is fixed to the upper end of the height adjustment screw 411 to facilitate height adjustment.

[0042] The connecting structure 42 includes a first fixing plate 421, a third fixing plate 422, and a connecting column 423. The connecting column 423 extends perpendicularly through the second fixing plate 5 and slidably engages with the second fixing plate 5. The first fixing plate 421 is positioned at the upper end of the connecting column 423 and is bolted to the upper ends of the two connecting columns 423. The third fixing plate 422 is positioned at the lower end of the connecting column 423 and is bolted to the lower ends of the two connecting columns 423. The first fixing plate 421, the second fixing plate 5, and the third fixing plate 422 are parallel to each other. The height adjustment screw 411 extends through the first fixing plate 421 and is rotationally connected to the first fixing plate 421 via a bearing.

[0043] Specifically, a sliding sleeve 424 that cooperates with the connecting column 423 is installed on the second fixing plate 5. Two groups of connecting columns 423 and sliding sleeves 424 are provided and are symmetrically arranged on the left and right sides of the second fixing plate 5 about the axis of the height adjustment screw 411.

[0044] When the operating handle 413 controls the height adjustment screw 411 to rotate, the internal threaded sleeve 412 is fixed on the second fixed plate 5 and remains stationary. The relative rotation of the height adjustment screw 411 and the internal threaded sleeve 412 will drive the height adjustment screw 411 to move along the axial direction of the height adjustment screw 411, thereby realizing the overall height lifting of the first fixed plate 421, the connecting column 423 and the third fixed plate 422, thereby controlling the lifting and lowering of the clamping assembly 3 through the third fixed plate 422.

[0045] 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.

[0046] The operating process of Example 1 of the present application is as follows: When the device begins operation, the ink tank is manually placed on the placement platform 2, the position of the ink tank is moved, and the relative position of the ink tank and the bottom end of the pressure plate 33 is adjusted until the ink tank and the bottom end of the pressure plate 33 are aligned. The height adjustment assembly is adjusted by manually turning the operating handle 413. At this time, the height adjustment screw 411 rotates, and the third fixed plate 422 lowers the pressure assembly 3 along the axis of the height adjustment screw 411. When the pressure plate 33 descends and presses on the air barrier membrane of the ink tank, because the pressure plate 33 is a plate with a curved surface on the bottom and a thick center and thin edges, the pressure plate 33 can drive the air between the membrane and the ink from the center to the periphery, thereby discharging it. At the same time, the vibrator 34 above the pressure plate 33 causes the pressure plate 33 to vibrate. The vibration of the pressure plate 33 causes the ink to fill the gap below the membrane, effectively preventing gas residue. The operating handle 413 is then turned to raise the pressure assembly 3.

[0047] Example 2

[0048] refer to Figure 2This embodiment differs from the first embodiment in that the height adjustment assembly 4 includes a fourth fixing plate 44, a fifth fixing plate 45, and a cylinder 43. The fourth fixing plate 44 is bolted to the upper end of the frame 1. The cylinder 43 is a dual-axis cylinder with its movable axis facing downward. The upper end of the cylinder 43 is bolted to the fourth fixing plate 44, while the lower end of the cylinder 43 is bolted to the fifth fixing plate 45. The fifth fixing plate 45 is bolted to the connecting plate 31. The overall lifting and lowering of the clamping assembly 3 is controlled by controlling the extension and retraction of the cylinder 43.

[0049] The implementation principle of Example 2 of the present application is: using the cylinder 43 to drive the automatic lifting and lowering of the clamping assembly 3, the lifting speed of the pressing plate 33 is faster, and the pressure of the pressing plate 33 can be uniformly controlled by air pressure, making the use of the film kneading device more convenient and efficient.

[0050] 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.
