[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0029] Refer to Figure 1 and Figure 2, An embodiment provided by the present utility model: An ink squeezing mechanism capable of evenly supplying ink to an ink fountain, including a top plate 1. A reciprocating working component is installed at the bottom of the top plate 1, and a workbench 15 is installed at the bottom of the reciprocating working component. A chute 2 is opened at the top of the workbench 15, and a slider 3 is slidably connected inside the chute 2. Both sides of the front part of the workbench 15 are fixedly connected with a first support 11. A second motor 19 is fixedly connected to the left side of the left first support 11. A rotating shaft 25 is rotatably connected between the two first supports 11. Two spline shafts 18 are fixedly connected to the middle of the rotating shaft 25. A driving gear 12 is slidably connected to the outer periphery of the left spline shaft 18, and the right spline shaft 18 is fixedly connected with a driving gear 12. A distance adjusting component is arranged on the left side of the workbench 15. A second support 17 is fixedly connected to the front side of the distance adjusting component. Fixing plates 13 are fixedly connected to the front and rear sides of the bottom of the distance adjusting component and the front and rear sides of the bottom of the workbench 15. Pressing rollers 26 are rotatably connected between the two fixing plates 13 on the same side. The front end of the pressing roller 26 is fixedly connected with a driven gear 14 through a rotating shaft. The driving gear 12 and the driven gear 14 are meshed and connected. The reciprocating working component includes a first motor 6. The bottom end of the first motor 6 is fixedly connected to the top end of the top plate 1. The output end of the first motor 6 is fixedly connected with a rotating rod 5. The bottom end of the rotating rod 5 is fixedly connected with a turntable 4. A thin rod 8 is fixedly connected to the front side of the bottom of the turntable 4. A hollow shell 7 is slidably connected to the outside of the thin rod 8. Support blocks 23 are fixedly connected to both sides of the bottom of the top plate 1. Moving plates 9 are slidably connected inside the two support blocks 23. The end of the moving plate 9 away from the support block is fixedly connected to the outer wall of the hollow shell 7. Connecting plates 10 are fixedly connected to the bottoms of the two moving plates 9. The top of the workbench 15 is fixedly connected to the bottom of the connecting plate 10. Support columns 22 are fixedly connected to the four peripheries of the bottom of the top plate 1. The top of the hollow shell 7 is slidably connected to the bottom of the turntable 4. The left side of the left driving gear 12 is rotatably connected to the right side of the second support 17. The outer periphery of the left spline shaft 18 penetrates through the inside of the second support 17. The left side of the rotating shaft 25 is fixedly connected to the output end of the second motor 19.
[0030] Specifically, in order to achieve the purpose of evenly supplying ink to the ink fountain, the first motor 6 is started at this time to drive the rotating rod 5. While the rotating rod 5 rotates, it drives the turntable 4 and the thin rod 8 to rotate. Because the hollow shell 7 limits the thin rod 8, the thin rod 8 can only move left and right reciprocally, thereby driving the moving plates 9 on both sides of the outside of the hollow shell 7 to move left and right reciprocally at the same time. And the support block 23 plays a role of limiting and supporting the moving plate 9 at this time, thereby driving the squeezing mechanism below the connecting plate to move left and right reciprocally, thereby achieving the purpose of uniform ink supply, greatly improving the practicability of the device.
[0031] Refer to Figure 1 and Figure 3, the distance adjustment component includes a sliding plate 16. The top of the sliding plate 16 is fixedly connected to the bottom of the slider 3. A screw rod 20 is rotatably connected to the left side of the sliding plate 16. A fixed block 24 is threadedly connected to the middle of the screw rod 20. The top of the fixed block 24 is fixedly connected to the bottom edge of the workbench 15. A handle (21) is fixedly connected to the left side of the screw rod 20. The top of the sliding plate 16 is slidably connected to the bottom of the workbench 15.
[0032] Specifically, in order to minimize the waste of ink as much as possible and enable the extrusion work to be completed faster, it is necessary to adjust the distance between the two extrusion rollers 26 at this time. When the screw rod 20 is rotated, the screw rod 20 will push the sliding plate 16 and the slider 3 to move during the forward movement. Since the left-side driving gear 12 and the support two 17 are fixedly connected, and the support two 17 and the sliding plate 16 are fixedly connected, and the inner hole of the support two 17 is very large enough for the left-side spline shaft 18 to rotate inside without affecting the movement of the support two 17 on its outer periphery. Therefore, when the sliding plate 16 moves, it will drive the support two 17 and the left-side driving gear 12 to move synchronously, thereby driving the extrusion roller 26 at the bottom of the sliding plate 16 to approach the other extrusion roller 26, completing the adjustment of the gap between the extrusion rollers 26, and then performing the work of extruding the bagged ink. At this time, start the motor two 19 to drive the rotating shaft 25, thereby driving the two driving gears 12 to rotate. Since the driving gear 12 and the driven gear 14 are meshed, the driven gear 14 will be driven to rotate when the driving gear 12 rotates, and the fixed block 13 plays a role in fixedly supporting the extrusion roller, thereby driving the two extrusion rollers 26 to extrude the bagged ink and completing the extrusion work of the bagged ink.
[0033] Working principle: When the ink extrusion mechanism needs to be used, first, it is necessary to adjust the distance between the two extrusion rollers 6. At this time, rotate the screw rod 20 to push the sliding plate 16 to move to the right, thereby driving the left-side extrusion roller 26 to approach the other extrusion roller 26 until the appropriate distance is adjusted. After the adjustment is completed, place the bagged ink between the two extrusion rollers 26, start the motor two 19 to drive the rotating shaft 25 to rotate, drive the two driving gears 12 to rotate. Since the driving gear 12 and the driven gear 14 are meshed, the extrusion roller 26 is driven to perform extrusion. In order to evenly extrude the ink into the ink hopper, at this time, start the motor one 6 to drive the rotating rod 5 to rotate, thereby driving the turntable 4 and the thin rod 8 to rotate. Since the hollow shell 7 limits the thin rod 8, the thin rod 8 drives the hollow shell 7 to move left and right, and drives the moving plate 9 to move left and right, achieving the purpose of uniform ink supply through horizontal reciprocating movement during ink extrusion.
[0034] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
