Description

Technical Field

[0001] This utility model relates to the field of ink filling technology, and in particular to an enhanced design for ink bag filling. Background Technology

[0002] In the printing industry, ink is a critical consumable, and its packaging and refilling methods directly impact production efficiency. Currently, most inks are packaged in cans, which is relatively convenient for refilling, allowing for quick replenishment of the ink fountain in the printing press. However, a small portion of inks are packaged in bags. While this packaging method may have advantages in terms of cost, transportation, and storage, it presents numerous inconveniences when refilling. Refilling ink via bags lacks a fast and efficient method, resulting in cumbersome and inefficient operations when ink needs to be replenished during the printing process.

[0003] For example, Chinese patent document CN218536057U discloses an ink extrusion device for a printing press. In this technical solution, the main structure includes an ink fountain, a support, a fixed rod, a threaded rod, a drive motor, a threaded plate, a small motor, a screw rod, a fixed plate, a hydraulic cylinder, an extrusion plate, and extrusion rollers. The drive motor drives the threaded rod to rotate, causing the threaded plate to move; the small motor drives the screw rod to rotate, adjusting the spacing of the fixed plates to fix the ink bag; the hydraulic cylinder drives the extrusion plate to move downwards, extruding ink from the placement opening and holes. Simultaneously, two extrusion rollers slidably connected inside the extrusion plate assist in the extrusion, and an arc-shaped block connected to an elastic rod at the bottom of the threaded plate helps to position the ink bag.

[0004] However, while this technical solution achieves the ink-filling function of ink bags to a certain extent, it has significant drawbacks: First, its structure is complex and energy-intensive, requiring three independent power sources—a drive motor, a small motor, and a hydraulic cylinder—to work together, resulting in a long transmission chain and low mechanical efficiency. In particular, the compression method, where the hydraulic cylinder pushes the extrusion plate and then transmits the energy to the extrusion rollers, involves multiple conversions of hydraulic energy into mechanical energy and then into extrusion energy, leading to significant energy loss. Second, manual operation is cumbersome. When changing ink bags, the distance between the two fixing plates must be manually adjusted using a small motor-driven screw to clamp or release the ink bag. Furthermore, the lack of an automatic lifting and adaptation design means the ink bag's position requires repeated manual calibration, resulting in low production efficiency. Utility Model Content

[0005] To overcome the shortcomings of the prior art, a smart ink-filling device for spot color inks based on extrusion ink supply is provided.

[0006] This utility model is achieved through the following technical solution: a smart ink-filling device for spot color ink based on extrusion ink supply, comprising: an extrusion device for extruding ink bags, with guide rail assemblies slidably connected to both sides of the extrusion device and sliding up and down along the guide rail assemblies; a clamping assembly disposed above the extrusion device for fixing an inverted ink bag; the extrusion device comprising: a bracket; a servo motor mounted on the bracket; an extrusion roller assembly connected to the servo motor, including a first extrusion roller and a second extrusion roller forming an extrusion gap through which the ink bag can pass; and a gear transmission mechanism mounted on the bracket, wherein the servo motor drives the extrusion device to slide up and down along the guide rail assemblies via the gear transmission mechanism.

[0007] In a preferred embodiment of the present invention, the gear transmission mechanism includes a drive shaft and drive gears provided on both sides thereof. The drive gears mesh with the driven gears provided on the extrusion roller assembly, thereby driving the extrusion roller assembly to rotate.

[0008] In a preferred embodiment of this utility model, the output end of the servo motor is provided with a driving gear that meshes with the driven gear.

[0009] In a preferred embodiment of this utility model, the guide rail assembly includes a mounting plate and a moving rack and a connecting guide rail mounted on the mounting plate; the moving rack is arranged along the length direction of the mounting plate and meshes with the drive gear.

[0010] In a preferred embodiment of this utility model, the bracket is provided with sliding grooves on both sides that fit into the connecting guide rail.

[0011] In a preferred embodiment of this utility model, an ink detection device is mounted on the support, and the ink detection device is mounted on both sides of the extrusion roller assembly.

[0012] In a preferred embodiment of the present invention, the clamping assembly includes a cylinder, a stop gauge, and a clamp. The clamp is mounted on the stop gauge. The cylinder is used to control the extension or retraction of the stop gauge, and the clamp is used to clamp one end of the inverted ink bag.

[0013] In a preferred embodiment of this utility model, the drive shaft, the first extrusion roller, and the second extrusion roller are arranged in parallel on the support.

[0014] In a preferred embodiment of this utility model, the support is provided with an outlet for the ink bag to pass through; the outlet and the extrusion gap are on the same axis.

[0015] As a preferred embodiment of the present invention, it also includes a working tank and a working tank cover, the working tank cover being provided with an ink filling port; the extrusion gap and the other end of the ink bag are aligned with the ink filling port.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The intelligent ink filling device for spot color inks based on extrusion ink supply has a reasonable overall structure design. Through the coordinated work of the extrusion device, guide rail assembly and clamping assembly, it can effectively perform extrusion ink filling operation on the ink bag. The extrusion device is driven by a servo motor and moves up and down along the guide rail assembly, which improves the automation level and work efficiency of ink filling.

[0018] Furthermore, the use of a gear transmission mechanism ensures stable and accurate transmission, guaranteeing that the extrusion roller assembly extrudes the ink bag at appropriate speed and torque, thus ensuring the consistency and stability of the extrusion effect.

[0019] Furthermore, the direct meshing of the driving gear and driven gear reduces transmission links, improves transmission efficiency, and enhances transmission reliability, enabling more precise control of the rotation of the extrusion roller assembly.

[0020] Furthermore, the lifting and lowering motion of the extrusion device is achieved through the meshing of the moving rack and the drive gear. This transmission method has a simple structure, runs smoothly, and can precisely control the lifting and lowering position of the extrusion device, so that the first extrusion roller and the second extrusion roller roll back and forth to completely squeeze out the ink in the ink bag.

[0021] Furthermore, the cooperation between the sliding groove and the connecting guide rail improves the stability and accuracy of the lifting movement of the extrusion device, reduces problems such as uneven extrusion caused by shaking or deviation, and ensures the quality of ink addition.

[0022] Furthermore, the ink detection device can provide timely feedback on the ink status, allowing operators to understand the ink filling process promptly and take timely measures to adjust when abnormalities occur, thus improving the accuracy and reliability of ink filling.

[0023] Furthermore, the clamping assembly controls the movement of the stop gauge and clamp through a cylinder, realizing automatic clamping and release of the ink bag. The operation is convenient and quick, improving work efficiency, while also ensuring the stability and reliability of clamping.

[0024] Furthermore, the parallel layout reduces motion interference between components, improves the smoothness and efficiency of transmission, reduces equipment wear and failure rate, and extends equipment service life.

[0025] Furthermore, the outlet and the extrusion gap are on the same axis, ensuring that the ink bag can smoothly enter the extrusion gap, reducing the resistance of the ink during the entry process, improving the extrusion efficiency, and also avoiding the problem of uneven extrusion caused by ink deviation.

[0026] Furthermore, the squeezing gap and the other end of the ink bag are aligned with the ink filling port, allowing the ink to flow accurately into the working tank, avoiding ink leakage and waste, improving the accuracy and efficiency of ink filling, and also ensuring a clean working environment.

Detailed Implementation

[0036] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0037] In the following description, terms such as “inner,” “outer,” “upper,” “lower,” “left,” and “right” are used only to facilitate the description of the embodiments and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0038] like Figures 1 to 5 As shown, the intelligent ink dispensing device for spot color inks based on extrusion ink supply mainly consists of an extrusion device 1, a guide rail assembly 3, and a clamping assembly 4. The extrusion device 1 is used to extrude ink bags 2, and its two sides are slidably connected to the guide rail assembly 3, allowing it to slide up and down on the guide rail assembly 3. The clamping assembly 4 is located above the extrusion device 1 and is used to fix the inverted ink bag 2.

[0039] The extrusion device 1 includes a support 11, a servo motor 12, an extrusion roller assembly 13, and a gear transmission mechanism 14. The servo motor 12 is mounted on the support 11 and drives the extrusion roller assembly 13 to rotate through the gear transmission mechanism 14. At the same time, it drives the extrusion device 1 to slide up and down along the guide rail assembly 3 to achieve the extrusion and conveying of the ink bag 2.

[0040] The specific working process is as follows: The inverted ink bag 2 is fixed in place by the clamping assembly 4. One end of the ink bag 2 passes through the outlet 110 of the extrusion device 1 and enters the extrusion gap 130 of the extrusion roller assembly 13, thus pre-installing the ink bag 2. The servo motor 12 is started, which drives the extrusion roller assembly 13 to rotate through the gear transmission mechanism 14, while simultaneously driving the extrusion device 1 to rise or fall along the guide rail assembly 3. Under the extrusion action of the extrusion roller assembly 13, the ink in the ink bag 2 is squeezed out and flows into the working tank 6. The extruded ink bag 2 extends out from the outlet 110.

[0041] Specifically, the gear transmission mechanism 14 includes a drive shaft 141 and drive gears 142 on both sides thereof. The drive gears 142 mesh with the driven gears 133 on the extrusion roller assembly 13. The output end of the servo motor 12 is provided with a drive gear 121 that meshes with the driven gear 133. When the servo motor 12 is started, the drive gear 121 drives the driven gear 133 to rotate, and at the same time, the drive gears 142 on the drive shaft 141 also rotate. Because the drive gears 142 mesh with the driven gears 133, the stability of the rotation of the extrusion roller assembly 13 is further ensured.

[0042] In practical applications, this gear transmission method ensures that the extrusion roller assembly 13 extrudes the ink bag 2 at a suitable speed and torque, guaranteeing the consistency and stability of the extrusion effect. For example, in the printing production process, according to different printing requirements and ink characteristics, the rotation speed of the extrusion roller assembly 13 can be changed by adjusting the speed of the servo motor 12, thereby controlling the ink extrusion speed.

[0043] In this embodiment, the extrusion roller assembly 13 includes a first extrusion roller 131 and a second extrusion roller 132. The first extrusion roller 131 and the second extrusion roller 132 are polyurethane rollers. Polyurethane material has extremely high wear resistance and can effectively resist the wear of particulate matter or hard impurities in ink, extend the service life of the extrusion rollers, and reduce the frequency and cost of equipment maintenance.

[0044] Specifically, the guide rail assembly 3 includes a mounting plate 31, a moving rack 32 mounted on the mounting plate 31, and a connecting guide rail 33. The moving rack 32 is arranged along the length of the mounting plate 31 and meshes with the drive gear 142. The bracket 11 has sliding grooves 111 on both sides that engage with the connecting guide rail 33. When the servo motor 12 drives the drive gear 142 to rotate via the gear transmission mechanism 14, the drive gear 142 meshes with the moving rack 32, thereby causing the extrusion device 1 to slide up and down along the connecting guide rail 33.

[0045] Furthermore, a driven gear 133 is provided on one side of both the first extrusion roller 131 and the second extrusion roller 132, such as... Figure 2 As shown, the driving gear 121 drives the driven gear 133 on one side of the second extrusion roller 132 to rotate, which in turn drives the driven gear 133 on one side of the first extrusion roller 131 to rotate. The driven gear 133 on one side of the first extrusion roller 131 drives the drive gear 142 to rotate, and the drive gear 142 drives the drive shaft 141 to rotate, so that the drive gears 142 on both sides move up and down synchronously in the moving rack 32, thereby realizing the lifting and sliding motion of the extrusion device 1 and the extrusion operation of the extrusion device 1.

[0046] The bracket 11 has side plates 112 on both sides for mounting the sliding groove 111. The upper end of the side plate is vertically fixed to the bottom surface of the bracket 11, which facilitates the installation of the sliding groove 111, prevents the driven gear 133, the driving gear 121 and the drive gear 142 from interfering with the sliding groove 111, and avoids malfunctions in lifting and pressing rotation operations.

[0047] During the extrusion process, as the ink in the ink bag 2 decreases, the extrusion device 1 can slowly rise along the guide rail assembly 3, maintaining effective extrusion of the ink bag 2. This method of achieving the lifting and lowering movement of the extrusion device 1 through the meshing of the moving rack 32 and the drive gear 142 is simple in structure, runs smoothly, and can precisely control the lifting and lowering position of the extrusion device 1 to meet the ink filling needs at different heights. For example, when processing ink bags 2 of different sizes, the operation of the servo motor 12 can be adjusted to raise and lower the extrusion device 1 to a suitable position, ensuring that the ink can be fully extruded.

[0048] Specifically, an ink detection device 5 is mounted on the support 11, and the ink detection device 5 is mounted on both sides of the extrusion roller assembly 13. During the extrusion process, the ink detection device 5 monitors the ink status on both sides of the extrusion roller assembly 13 in real time, such as parameters like ink flow rate and pressure. When the ink detection device 5 detects an abnormal decrease in ink flow rate or an abnormal increase in pressure, it may mean that the ink bag 2 is about to run out or is clogged. At this time, the ink detection device 5 will feed the signal back to the control system, and the operator can take timely measures based on the feedback information, such as replacing the ink bag 2 or checking whether the equipment is faulty.

[0049] The application of this ink detection device 5 can provide timely feedback on the status of the ink, making it easier for operators to understand the ink replenishment situation, improving the accuracy and reliability of ink replenishment, and reducing printing interruptions or quality degradation caused by ink supply problems.

[0050] Furthermore, the clamping assembly 4 includes a cylinder 41, a stop gauge 42, and a clamp 43. The clamp 43 is mounted on the stop gauge 42, and the cylinder 41 controls the extension or retraction of the stop gauge 42. When it is necessary to clamp an inverted ink bag 2, the cylinder 41 controls the stop gauge 42 to extend, so that the clamp 43 reaches the appropriate position to clamp one end of the ink bag 2. The clamp 43 can adopt an elastic clip or other suitable clamping structure to ensure stable and reliable clamping of the ink bag 2. After ink filling is completed, the cylinder 41 controls the stop gauge 42 to retract, releasing the ink bag 2, making it convenient for the operator to replace with a new ink bag 2.

[0051] This clamping assembly 4, which controls the movement of the stop gauge 42 and the clamp 43 through the cylinder 41, realizes automatic clamping and release of the ink bag 2. It is convenient and quick to operate, improves work efficiency, and at the same time ensures the stability and reliability of clamping, reducing errors and safety hazards that may be caused by manual operation.

[0052] The drive shaft 141, the first extrusion roller 131, and the second extrusion roller 132 are arranged in parallel on the support 11. This parallel arrangement allows the gear transmission mechanism 14 to drive the extrusion roller assembly 13 more smoothly, ensuring coordinated movement among the components. In actual operation, the parallel arrangement reduces interference between components, improving transmission smoothness and efficiency. For example, it avoids additional friction and wear caused by angular deviations or uncoordinated movements between components, reducing equipment wear and failure rates and extending equipment lifespan. Simultaneously, it ensures the uniformity and stability of the extrusion roller assembly 13's extrusion of the ink bag 2, improving ink dispensing quality.

[0053] The support 11 is provided with an outlet 110 for the ink bag 2 to pass through, and the outlet 110 and the extrusion gap 130 are on the same axis. The ink bag 2 passes through the outlet 110 and enters the extrusion gap 130. Under the extrusion action of the extrusion roller assembly 13, the ink is squeezed out, and the extruded ink bag 2 extends out from the outlet 110.

[0054] Because the outlet 110 and the extrusion gap 130 are on the same axis, the ink bag 2 can smoothly enter the extrusion gap 130, reducing the resistance of the ink during the entry process and improving the extrusion efficiency. At the same time, it also avoids uneven extrusion caused by ink misalignment. For example, if the outlet 110 and the extrusion gap 130 are not on the same axis, the ink bag 2 may misalign when entering the extrusion gap 130, resulting in over-extrusion on one side and under-extrusion on the other, affecting the ink extrusion effect and ink filling quality. Furthermore, it ensures that the ink bag 2 will not get stuck inside the extrusion device after extrusion.

[0055] The extrusion ink filling mechanism also includes a working tank 6 and a working tank cover 7. The working tank cover 7 is provided with an ink filling port 71, and the extrusion gap 130 and the other end of the ink bag 2 are aligned with the ink filling port 71. During the extrusion process, the ink squeezed out from the ink bag 2 flows directly into the ink filling port 71 through the extrusion gap 130 and enters the working tank 6. This design allows the ink to flow accurately into the working tank 6, avoiding ink leakage and waste, improving the accuracy and efficiency of ink filling, and also ensuring a clean working environment.

[0056] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above.
