Description

Technical Field

[0001] This utility model relates to the field of printer technology, specifically to a printer ink cartridge accurate alignment component. Background Technology

[0002] UV printer ink cartridges are divided into large ink cartridges and secondary ink cartridges. The large ink cartridge stores ink and circulates it through an external ink pump. Its black casing reduces sunlight exposure and prevents ink reaction. The secondary ink cartridge is located in the carriage and uses a negative pressure system to balance gravity and ink supply pressure, ensuring that the ink is delivered evenly and stably to the printhead.

[0003] In existing technologies, traditional large ink cartridges lack a fixed structure within the cartridge compartment. Multiple large ink cartridges are simply stacked together, which easily leads to misalignment when their ports are connected to the printhead piping, resulting in inaccurate matching and poor ink delivery. At the same time, the vibration generated by the ink flowing in the piping is directly transmitted to the loosely placed large ink cartridges, which not only exacerbates the misalignment problem at the large ink cartridge ports, but may also cause the connection between the large ink cartridges and the piping to loosen due to long-term vibration, leading to ink leakage and unstable printing quality (such as broken lines and color differences). Utility Model Content

[0004] The purpose of this invention is to provide a printer ink cartridge accurate alignment component to solve the problems mentioned in the background art, such as misalignment between the port and the pipeline, poor ink delivery, and increased misalignment and loosening due to pipeline vibration caused by the lack of a fixed structure inside the traditional large ink cartridge.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a printer ink cartridge accurate alignment component, comprising a support frame with an internal cavity, an directional guide groove formed on the upper working plane of the support frame, an ink cartridge disposed above the directional guide groove, a dynamic clamping unit for performing ink cartridge fixing and clamping operations disposed within the cavity, and a guide mechanism mechanically linked to the dynamic clamping unit. The dynamic clamping unit includes a displacement actuator extending outside the directional guide groove, the displacement actuator linearly displacing within the directional guide groove by the motion constraint of the guide mechanism, a clamping plate detachably connected to the support interface of the displacement actuator, and a deformable flexible floppy disk array distributed on the contact plane of the clamping plate facing the ink cartridge; the dynamic clamping unit achieves coordinated displacement of the displacement actuator within the directional guide groove through the constraint of the guide mechanism, thereby driving the clamping plate to position, clamp, and release the ink cartridge, while the flexible floppy disk array undergoes contact deformation adapted to the surface of the ink cartridge during the clamping process.

[0006] According to the preferred embodiment of this technical solution, the dynamic clamping unit includes a bearing seat disposed on the inner wall of the cavity, a bidirectional lead screw rotatably connected inside the bearing seat, the end of the bidirectional lead screw extending to the outside of the support frame and fixedly fitted with a knob, a drive plate being threadedly connected to the threaded section of the bidirectional lead screw, a column adapted to the directional guide groove being fixedly connected to the upper surface of the drive plate, and a receiving plate connected to the clamping plate being fixedly connected to the upper end of the column.

[0007] In a preferred embodiment of this technical solution, the guiding mechanism includes a slide rail disposed on the inner wall of the cavity, a slider slidably connected to the slide rail, and the surface of the slider being fixedly connected to the side end of the drive plate.

[0008] Based on the preferred embodiment of this technical solution, the bottom end face of the clamping plate is integrally provided with an annular protrusion, and the upper end face of the receiving plate is provided with a groove that matches the protrusion, with the protrusion inserted into the groove.

[0009] In the preferred embodiment of this technical solution, permanent magnets are provided on the contact surfaces of both the protrusion and the groove, and the contact surfaces of the protrusion and the groove are magnetically connected.

[0010] In a preferred embodiment of this technical solution, a cavity is provided on the upper end face of the receiving plate, a spring is provided on the inner wall of the cavity, a locking plate is fixedly connected to the extension end of the spring, and a button extending to the outside of the receiving plate is fixedly connected to the surface of the locking plate.

[0011] In a preferred embodiment of this technical solution, an extension plate is fixedly connected to the bottom of the clamping plate, and the surface of the extension plate is provided with an L-shaped bent plate that cooperates with the locking plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The coordinated action of the dynamic clamping unit driven by the bidirectional screw and the slide rail guiding mechanism ensures the accuracy of the linear displacement of the clamping plate, while adapting to the alignment requirements of ink cartridges of different sizes.

Detailed Implementation

[0021] 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.

[0022] Please see Figures 1-5This utility model provides two embodiments: a printer ink cartridge accurate alignment component, including a support frame 1 with an internal cavity, a directional guide groove 2 formed on the upper working plane of the support frame 1, an ink cartridge 3 disposed above the directional guide groove 2, a dynamic clamping unit for performing the fixed clamping operation of the ink cartridge 3 disposed in the cavity, and a guide mechanism mechanically linked with the dynamic clamping unit, the dynamic clamping unit including a displacement actuator extending outside the directional guide groove 2, the displacement actuator performing linear displacement within the directional guide groove 2 by the motion constraint of the guide mechanism, and the support boundary of the displacement actuator... The device is detachably connected to a clamping plate 4. A deformable flexible floppy disk array 5 is distributed on the contact surface of the clamping plate 4 facing the ink cartridge 3. The dynamic clamping unit achieves coordinated displacement of the displacement actuator within the directional guide groove 2 through the constraint of the guide mechanism, thereby driving the clamping plate 4 to position, clamp, and release the ink cartridge 3. Simultaneously, the flexible floppy disk array 5 undergoes contact deformation adapted to the surface of the ink cartridge 3 during clamping. The support frame 1, as the supporting structure for the accurate alignment of the entire ink cartridge 3 assembly, is made of metal, such as aluminum alloy, through casting or welding processes. Its interior forms a cavity to accommodate the dynamic clamping unit and... The guiding mechanism provides space for installation and movement. Ink cartridge 3, the ink storage component in the printer, is made of plastic and contains an ink storage chamber and ink outlet. Through contact with the clamping plate 4, the ink cartridge 3 is positioned, clamped, and released by the dynamic clamping unit, ensuring accurate installation on the carrier frame 1 and achieving precise alignment. The clamping plate 4 is made of metal, such as aluminum alloy. A deformable flexible floppy disk array 5 is distributed on the contact surface of the clamping plate 4 facing the ink cartridge 3. Driven by the displacement actuator, the clamping plate 4 moves closer to or further away from the ink cartridge 3, achieving accurate ink positioning. The flexible floppy disk array 5, made of flexible materials such as rubber or silicone, is used for clamping or releasing cartridge 3. It is connected to the clamping plate 4 by adhesive or embedding. During the clamping process, the flexible floppy disk array 5 generates contact deformation that adapts to the surface of cartridge 3. It can adaptively adjust according to the shape and unevenness of the surface of cartridge 3, increase the contact area and friction between clamping plate 4 and cartridge 3, improve the stability and reliability of clamping, and reduce damage to the surface of cartridge 3. The guiding mechanism is used to precisely guide and constrain the movement of the displacement actuator, ensuring the linearity of the movement of the displacement actuator.

[0023] Please see Figures 1-3A further solution based on this embodiment is as follows: The dynamic clamping unit includes a bearing seat 6 disposed on the inner wall of the cavity. A bidirectional lead screw 7 is rotatably connected inside the bearing seat 6. The end of the bidirectional lead screw 7 extends to the outside of the support frame 1 and is fixedly fitted with a knob 8. A drive plate 9 is threadedly connected to the threaded section of the bidirectional lead screw 7. A column 10 adapted to the directional guide groove 2 is fixedly connected to the upper surface of the drive plate 9. A receiving plate 11 connected to the clamping plate 4 is fixedly connected to the upper end of the column 10. The bearing seat 6 is made of metal, such as copper alloy, and has bearings installed inside. The bearing seat 6 provides rotational support for the bidirectional lead screw 7, ensuring that the bidirectional lead screw 7 can rotate smoothly and steadily. The bidirectional lead screw 7 is made of steel and has threads with opposite ends. When the knob 8 is rotated, the bidirectional lead screw 7 rotates under the drive of the knob 8. The drive plate 9 threadedly connected to the threaded section of the bidirectional lead screw 7 will move linearly in opposite directions along the bidirectional lead screw 7, thereby realizing the adjustment of the spacing of the clamping plate 4 to suit the needs of the machine. To accommodate the clamping requirements of ink cartridges 3 of different sizes, the knob 8 is made of plastic or metal and is fixed to the bidirectional lead screw 7 via threaded connection or interference fit. The function of the knob 8 is to allow the operator to manually rotate the bidirectional lead screw 7 to adjust the position of the drive plate 9. The drive plate 9 is made of metal, such as stainless steel. The drive plate 9 moves linearly under the drive of the bidirectional lead screw 7. At the same time, a column 10 adapted to the directional guide groove 2 is fixed to the upper surface of the drive plate 9, which converts the rotational motion of the bidirectional lead screw 7 into its own linear motion and drives the column 10 and the receiving plate 11 to move. The column 10 is made of metal, such as aluminum alloy, and is fixed to the drive plate 9 via welding or bolt connection. The column 10 serves to connect the drive plate 9 and the receiving plate 11, transmitting the motion of the drive plate 9 to the receiving plate 11. The receiving plate 11 is made of the same metal as the column 10 and is fixed to the column 10 via welding or bolt connection. The receiving plate 11 provides an installation support platform for the clamping plate 4.

[0024] Please see Figure 3 A further solution based on this embodiment is as follows: The guiding mechanism includes a slide rail 12 disposed on the inner wall of the cavity, and a slider 13 is slidably connected to the slide rail 12. The surface of the slider 13 is fixedly connected to the side end of the drive plate 9. The slide rail 12 is made of metal, such as stainless steel, and is fixed to the inner wall of the cavity by bolts or welding. The slide rail 12 provides a sliding track for the slider 13, ensuring that the slider 13 can move linearly along the direction of the slide rail 12. The slider 13 is made of metal or plastic material and has rolling elements installed inside. The slider 13 slides on the slide rail 12 with the movement of the drive plate 9, providing guidance and support for the movement of the drive plate 9 and ensuring the stability of the movement of the drive plate 9.

[0025] Example 1: Please refer to Figures 3-4A further solution based on this embodiment is as follows: the bottom end face of the clamping plate 4 is integrally provided with an annular protrusion 14, and the upper end face of the receiving plate 11 is provided with a groove 15 that matches the protrusion 14. The protrusion 14 is inserted into the groove 15. The protrusion 14 is made of the same metal material as the clamping plate 4 and is connected to the clamping plate 4 by casting or machining. When the clamping plate 4 is installed on the receiving plate 11, the protrusion 14 is inserted into the groove 15, which plays a role in positioning and fixing, and prevents the clamping plate 4 from shifting in the horizontal direction.

[0026] Please see Figures 3-4 A further solution based on this embodiment is as follows: permanent magnets are provided on the contact surfaces of both the protrusion 14 and the groove 15. The contact surfaces of the protrusion 14 and the groove 15 are magnetically connected. The permanent magnets are made of strong magnetic materials such as neodymium iron boron and are fixed on the contact surfaces of the protrusion 14 and the groove 15 by embedding or pasting. The magnetic connection method allows the protrusion 14 to be easily inserted into the groove 15 and fixed by magnetic adsorption, ensuring the connection stability between the clamping plate 4 and the receiving plate 11. It also facilitates the disassembly and installation of the clamping plate 4 and reduces the operational difficulty during the disassembly and installation process.

[0027] Example 2: Please refer to Figure 3 and Figure 5 A further solution based on this embodiment is as follows: a cavity 16 is formed on the upper end face of the receiving plate 11, and a spring 17 is provided on the inner wall of the cavity 16. A locking plate 18 is fixedly connected to the telescopic end of the spring 17. A button 19 extending to the outside of the receiving plate 11 is fixedly connected to the surface of the locking plate 18. The spring 17 is a compression spring, and its elastic coefficient is designed according to the locking force requirement of the locking plate 18 on the extension plate 20. In its natural state, the spring 17 enables the locking plate 18 to cooperate with the bent plate 21 on the extension plate 20 to lock the clamping plate 4. The locking plate 18 is made of metal. For example, stainless steel is used to fix the locking plate 18 to the telescopic end of the spring 17 by welding or bolting. The locking plate 18 can move horizontally under the action of the spring 17. When the extension plate 20 is inserted into the receiving plate 11, the locking plate 18 cooperates with the bending plate 21 to lock the clamping plate 4 on the receiving plate 11. The button 19 is made of plastic and is fixed to the locking plate 18 by adhesive or slot connection. The function of the button 19 is to allow the operator to manually press the locking plate 18 to compress the spring 17, so that the locking plate 18 is separated from the bending plate 21, thereby releasing the lock on the clamping plate 4 and facilitating the disassembly of the clamping plate 4.

[0028] Please see Figure 3 and Figure 5A further solution based on this embodiment is as follows: An extension plate 20 is fixedly connected to the bottom of the clamping plate 4. An L-shaped bent plate 21 that cooperates with the locking plate 18 is provided on the surface of the extension plate 20. The extension plate 20 is made of the same metal material as the clamping plate 4 and is fixed to the clamping plate 4 by welding or bolting. The bent plate 21 is made of the same metal material as the extension plate 20 and is connected to the extension plate 20 by machining. The bent plate 21 cooperates with the locking plate 18. When the locking plate 18 is in the action of the spring 17, it can hold the bent plate 21 to prevent the clamping plate 4 from moving in the horizontal direction and ensure the connection stability between the clamping plate 4 and the receiving plate 11.

[0029] Working principle: The operator first rotates the knob 8 on the outside of the support frame 1. The knob 8 drives the bidirectional lead screw 7 to rotate smoothly in the bearing seat 6. Since the bidirectional lead screw 7 has opposite threads at both ends, the drive plate 9, which is threaded to the threaded section of the bidirectional lead screw 7, will move linearly in opposite directions along the lead screw. When the drive plate 9 moves, the column 10 fixed to its upper surface moves synchronously. The column 10 drives the support plate 11 and the clamping plate 4 to move. During this process, the slider 13 of the guide mechanism slides on the slide rail 12. The slide rail 12 provides a linear sliding track for the slider 13. The slider 13 is fixed to the side end of the drive plate 9 to provide guidance and support for the movement of the drive plate 9, ensuring that the drive plate 9 moves smoothly in a straight line, thereby ensuring that the clamping plate 4 is accurately displaced to the position of the ink cartridge 3.

[0030] Example 1: When installing the clamping plate 4, the annular protrusion 14 integrally provided on the bottom end face of the clamping plate 4 is inserted into the matching groove 15 opened on the upper end face of the receiving plate 11. The permanent magnet provided on the contact surface of the protrusion 14 and the groove 15 is attracted by magnetic force, so that the protrusion 14 can be easily inserted into the groove 15 and fixed, preventing the clamping plate 4 from shifting in the horizontal direction, and realizing a stable connection between the clamping plate 4 and the receiving plate 11.

[0031] Example 2: When installing the clamping plate 4, press button 19 and simultaneously send the L-shaped bent plate 21 at the bottom of the clamping plate 4 into the cavity 16. Then, release button 19, and the spring 17 returns to its natural state, pushing the locking plate 18 to move horizontally, so that the locking plate 18 locks the bent plate 21, preventing the clamping plate 4 from moving in the horizontal direction, thus achieving a stable connection between the clamping plate 4 and the receiving plate 11.
