Description

Technical Field

[0001] This utility model belongs to the field of printer ink stack technology, and in particular relates to a multifunctional ink stack device. Background Technology

[0002] The printer ink stack system is a crucial component of a printer, primarily responsible for managing the printhead's status and ensuring it remains in optimal working condition when not printing. There are two main types of printer ink stack systems on the market: mechanical sliding structures and motor-driven solenoid valve structures. Mechanical sliding structures use a mechanical device to slide the sealing cover onto the printhead; they are simple in structure, highly reliable, and suitable for single-printhead or small-sized printers. Motor-driven solenoid valve structures use a motor and solenoid valve to control the opening and closing of the sealing cover; they are suitable for multi-printhead printers and provide better sealing for larger printheads. The ink stack system in a printer mainly performs the following functions:

[0003] 1. Printhead Moisturization: When the printer is not in use, the ink stack covers the printhead to prevent it from drying out, thus avoiding ink solidification inside the printhead and potential damage. This is usually achieved by an ink suction pad, which has a rubber pad that fits tightly against the printhead surface to create a sealed environment.

[0004] 2. Ink Recovery: During printing, the printhead undergoes periodic maintenance, such as ejecting waste ink to clear blockages. This waste ink is collected in the ink stack to prevent contamination of the printer's interior. The ink stack typically contains waste ink absorbing materials, such as sponges or ink-absorbing pads, which effectively absorb and store waste ink.

[0005] 3. Printhead Cleaning: Regularly clean the printhead to remove residual ink and impurities, keeping it unobstructed. Ink stacks are typically equipped with cleaning nozzles and cleaning fluid, allowing for automatic or manual cleaning of the printheads.

[0006] 4. Printhead sealing: When the printer is not used for a long time, the ink stack will seal the printhead to prevent external dust from entering and affecting printhead performance.

[0007] Printer printheads are high-precision, expensive products and a crucial component of printers. The printhead surface has many tiny nozzles; if these nozzles become clogged, ink interruptions will occur during printing. In the industry, the ink suction pad is exposed during printer operation. During prolonged, continuous printing, external dust can easily contaminate the ink suction pad. Additionally, some photosensitive inks, such as UV inks, are prone to curing when exposed to light. If the ink suction pad is exposed to natural light, the ink on it can solidify, leading to poor sealing between the ink stack and the printhead, and hindering printhead cleaning.

[0008] Therefore, we propose a multifunctional ink stack device. Utility Model Content

[0009] The purpose of this invention is to provide a multifunctional ink stack device that solves the existing problems.

[0010] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

Several track grooves are opened on both opposite surfaces of the lifting drive plate. The track grooves are combined grooves formed by connecting horizontal grooves and inclined grooves. A plug screw C passes through the vertical guide groove and the track groove in sequence and is fixedly connected to the ink stack lifting platform. An ink absorption pad fixing plate is fixed on the upper surface of the ink stack lifting platform.

[0012] A horizontal plate is fixed between the two receiving partitions. A motor is fixed to one surface of the horizontal plate. The output shaft of the motor extends through the horizontal plate into the maintenance station base and is connected to a lead screw via a coupling. A lead screw nut is threaded onto the circumferential side of the lead screw. The lead screw nut is fixed to the lifting drive plate, and the other end of the lead screw is fixed to a bearing seat inside the maintenance station base.

[0013] A sensor is fixed on the inner bottom surface of the maintenance station base, and a lifting sensor plate is fixed on the left end face of the ink stack lifting platform; the position of the sensor is adapted to the lifting sensor plate, and the sensor and the lifting sensor plate cooperate with each other.

[0014] Furthermore, each of the translation guide groove, vertical guide groove, and track groove on the same surface has at least two grooves.

[0015] Furthermore, the rack on the sliding cover meshes with the secondary gear of the sliding cover transmission, and the rack on the lifting drive plate meshes with the primary gear of the sliding cover transmission.

[0016] This utility model has the following beneficial effects:

[0017] This invention effectively covers the ink-absorbing pad through an automatic sliding cover design, preventing external dust contamination and light-curing of photosensitive ink, thus ensuring long-term stable printhead operation. A sensor, in conjunction with a lifting sensor plate and a combined guide structure, enables precise lifting and positioning of the ink stack lifting platform, improving printhead sealing and cleaning. A gear-connecting shaft and multi-stage transmission wheel design, combined with a motor-driven lead screw mechanism, achieve synchronized and coordinated movement of the sliding cover and lifting platform, resulting in a compact structure and smooth operation. Integrating printhead moisturizing, waste ink recovery, cleaning, and sealing functions, it is compatible with various printer models, offering strong expandability and meeting high-precision printing requirements.

[0032] A horizontal plate 207 is fixed between two receiving partitions 202. A motor 15 is fixed on one surface of the horizontal plate 207.

[0036] Please see Figures 1-6 As shown in the figure, this embodiment illustrates the working principle of a multifunctional ink stack device:

[0037] like Figure 1As shown, at this time, the sliding cover 1 is in the state of covering the ink absorption pad. The motor 15 rotates, driving the lead screw 13 to rotate. The lead screw nut 12 and the lifting drive plate 7 are fixed together. The plug screw B205 on the lifting drive plate 7 is fixed in the translation guide groove 203 of the maintenance station base 2. The lifting drive plate 7 can only move horizontally. The lead screw nut 12 pushes the lifting drive plate 7 to move to the right. The rack at the top of the lifting drive plate 7 drives the sliding cover transmission first-stage wheel 8 to rotate. The sliding cover transmission first-stage wheel 8 drives the gear connecting shaft 5 to rotate. The gear connecting shaft 5 drives the sliding cover transmission second-stage wheel 3 to rotate. The sliding cover transmission second-stage wheel 3 drives the sliding cover 1 to move to the left. The round shaft part of the plug screw C206 fixed on the ink stack lifting platform 9 is in the track groove 701 of the lifting drive plate 7 and the vertical guide groove 204 on the receiving partition 202. The vertical guide groove 204 on the receiving partition 202... The guide groove 204 ensures that the ink stack lifting platform 9 can only move up and down. When the track groove 701 of the lifting drive plate 7 moves to the right, the entire operation is divided into three stages. In the first stage, when the lifting drive plate 7 moves to the right, the sliding cover 1 moves to the left, and the locking screw C206 on the ink stack lifting platform 9 is first lifted up, allowing the ink stack lifting platform 9 to rise. At this time, the lifting sensor 17 separates from the sensor 18 and leaves the origin. In the second stage, the lifting drive plate 7 continues to move to the right, and the sliding cover 1 continues to move to the left. The ink stack lifting platform 9 remains stationary, and the sliding cover 1 makes room for the ink absorption pad fixing plate 10 to rise. In the third stage, the lifting drive plate 7 continues to move to the right, and the locking screw C206 on the ink stack lifting platform 9 is lifted up, allowing the ink stack lifting platform 9 to rise. In the third stage, printhead cleaning and printhead sealing can be completed. When the machine needs to print, motor 15 reverses, lifting drive plate 7 moves to the left, ink stack lifting platform 9 lowers to its original position, and sliding cover 1 covers the ink absorption pad. For flash printing, the ink can be directly sprayed into the flash spray slot on sliding cover 1.
