Description

Technical Field

[0001] This utility model belongs to the field of printing machine technology and relates to an ink anti-splatter device. Background Technology

[0002] In printing equipment, when the printing roller rotates at high speed, the ink on its surface is easily splashed due to centrifugal force. Especially when changing printing rollers of different diameters (such as from Φ120mm to Φ300mm), traditional ink troughs and fixed cover plates are difficult to adapt to the roller diameter changes synchronously: if the position of the ink trough is not adjustable, it cannot be guaranteed that the ink delivery roller is always immersed in ink; if the cover plate is a rigid fixed structure, it cannot be close to the roller surface to form an effective shield when using small diameter printing rollers, causing ink to be thrown out from the excessive gap between the roller surface and the cover plate, resulting in equipment contamination and ink waste.

[0003] In existing technologies, although some devices are equipped with covers, they are mostly fixed as a whole or require tools to disassemble. This means that the covering position cannot be dynamically adjusted according to the diameter of the printing roller, and it is also inconvenient for daily maintenance. At the same time, the height of the ink tank is fixed, and it cannot be adjusted to match the size of the printing roller, which affects the stability of ink application and the anti-splatter effect, indicating that there is considerable room for improvement. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing an ink splash prevention device.

[0005] The objective of this utility model can be achieved through the following technical solution: an ink anti-splatter device, comprising:

[0006] Printing roller;

[0007] An ink reservoir plate, which is located below the printing roller and can be raised and lowered relative to the printing roller;

[0008] An ink cover plate is located above the ink trough plate, and one side of the ink cover plate is rotatably connected to the ink trough plate so that the other side of the ink cover plate can be close to or away from the printing roller.

[0009] The ink anti-splatter device described above also includes two side baffles, which are located at both ends of the printing roller. The ink trough plate, the ink cover plate, and the side baffles form a semi-enclosed structure.

[0010] In the aforementioned ink splash prevention device, the side baffle is provided with a limiting frame, and the side of the ink cover plate away from the ink tank plate contacts the limiting frame.

[0011] In the aforementioned ink anti-splatter device, the limiting frame is provided with a slide rail, and the ink cover plate is provided with a sliding member, which is slidably connected to the slide rail.

[0012] In the aforementioned ink anti-splatter device, the sliding element is configured as a slide bar.

[0013] The ink anti-splatter device described above also includes a fixed base and a lifting drive device. The fixed base is fixed relative to the printing roller, the lifting drive device is connected to the fixed base, the ink tank plate is connected to the lifting drive device, and the lifting drive device can drive the ink tank plate to rise and fall.

[0014] In the aforementioned ink anti-splatter device, the lifting drive device is configured as a manual drive device.

[0015] In the aforementioned ink splash prevention device, the lifting drive device is configured as an automatic drive device.

[0016] The ink anti-splatter device described above also includes an ink delivery roller, which is movably connected to the ink trough plate so that it can approach or move away from the printing roller.

[0017] In the aforementioned ink anti-splatter device, the ink cover plate is provided with a handle.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: By adjusting the lifting of the ink trough plate and rotating the ink cover plate, the relative positions of the two plates and the printing roller can be flexibly adjusted according to the diameter of the printing roller, so that the ink cover plate is close to the surface of the printing roller during operation, effectively blocking the ink thrown out from the roller surface during high-speed rotation, while facilitating the opening of the cover plate during maintenance, thus balancing sealing performance and ease of operation; the side baffles block the opening areas at both ends of the printing roller axially, forming a semi-enclosed cavity around the lower part and sides of the printing roller together with the ink trough plate and the ink cover plate, significantly reducing the path of ink overflow after being thrown out along the end face of the printing roller, effectively controlling the splash range, and keeping the equipment and surrounding environment clean; the limiting frame provides a stable support and positioning point for the ink cover plate, ensuring that it maintains the optimal blocking distance with the printing roller in the closed state, avoiding the cover plate from sagging or shifting due to vibration or gravity, and improving the reliability of sealing.

[0028] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0029] like Figures 1-3 As shown, an ink splash prevention device includes:

[0030] Printing roller 100;

[0031] Ink tray 200, which is located below the printing roller 100 and can be raised and lowered relative to the printing roller 100;

[0032] An ink cover plate 300 is located above the ink trough plate 200. One side of the ink cover plate 300 is rotatably connected to the ink trough plate 200, so that the other side of the ink cover plate 300 can be close to or away from the printing roller 100.

[0033] In this embodiment, by adjusting the lifting of the ink trough plate 200 and rotating the ink cover plate 300, the relative positions of the two plates and the printing roller 100 can be flexibly adjusted according to the diameter of the printing roller 100. This allows the ink cover plate 300 to be close to the surface of the printing roller 100 during operation, effectively blocking the ink thrown out from the roller surface during high-speed rotation. At the same time, it is convenient to open the cover plate during maintenance, thus balancing sealing and ease of operation.

[0034] like Figures 1-3 As shown, based on the above embodiment, it also includes a side baffle 400. There are two side baffles 400, which are located at the two ends of the printing roller 100 respectively. The ink trough plate 200, the ink cover plate 300 and the side baffles 400 form a semi-enclosed structure.

[0035] In this embodiment, the side baffle 400 blocks the opening areas at both ends of the printing roller 100 along the axial direction. Together with the ink trough plate 200 and the ink cover plate 300, it forms a semi-enclosed cavity surrounding the lower part and both sides of the printing roller 100. This significantly reduces the path of ink overflow after being thrown out along the end face of the printing roller 100, effectively controls the splash range, and keeps the equipment and surrounding environment clean.

[0036] like Figures 1-3 As shown, based on the above embodiment, the side baffle 400 is provided with a limiting frame 410, and the side of the ink cover plate 300 away from the ink tank plate 200 contacts the limiting frame 410.

[0037] In this embodiment, the limiting frame 410 provides a stable support and positioning point for the ink cover plate 300, ensuring that it maintains the optimal blocking distance with the printing roller 100 in the closed state, avoiding sagging or displacement of the cover plate due to vibration or gravity, and improving sealing reliability.

[0038] like Figures 1-3As shown, based on the above embodiment, the limiting frame 410 is provided with a slide rail 411, and the ink cover plate 300 is provided with a sliding member, which is slidably connected to the slide rail 411.

[0039] In this embodiment, the cooperation between the slide rail 411 and the sliding member enables the ink cover plate 300 to have both guiding and limiting functions during rotation. It can open and close smoothly, and automatically align with the limiting position when closed to prevent jamming or misalignment, thereby improving the smoothness of operation and the accuracy of repeated positioning.

[0040] like Figures 1-3 As shown, based on the above embodiment, the sliding member is configured as a slide bar 310.

[0041] In this embodiment, the slide bar 310 has a simple structure, high strength, and is easy to process. When it is used with the slide rail 411, it has low frictional resistance, stable operation, and is easy to install and maintain. It is suitable for the working environment of printing presses that are used for a long time and at high frequency.

[0042] like Figures 1-3 As shown, based on the above embodiment, it also includes a fixed base 210 and a lifting drive device 220. The fixed base 210 is fixed relative to the printing roller 100, the lifting drive device 220 is connected to the fixed base 210, the ink tank plate 200 is connected to the lifting drive device 220, and the lifting drive device 220 can drive the ink tank plate 200 to rise and fall.

[0043] In this embodiment, the height of the ink tank plate 200 is precisely controlled by the lifting drive device 220 to adapt it to the printing rollers 100 of different diameters (Φ120mm~Φ300mm), ensuring that the ink delivery roller 500 is always immersed in ink and reliably transfers ink, while maintaining a reasonable gap between the ink cover plate 300 and the printing roller 100, thus achieving full specification compatibility.

[0044] like Figures 1-3 As shown, based on the above embodiment, the lifting drive device 220 is configured as a manual drive device.

[0045] Specifically, the manual drive device includes: a lead screw, which is vertically arranged and its lower end is fixedly connected to the ink tank plate 200; a nut seat, which is fixedly installed on the fixed base 210, and the lead screw passes through the nut seat and is threadedly engaged with it; and a handwheel, which is fixedly connected to the upper end of the lead screw or the outer periphery of the nut seat; rotating the handwheel can drive the lead screw to move up and down relative to the nut seat, thereby driving the ink tank plate 200 to rise and fall.

[0046] In this embodiment, the manual adjustment structure requires no electricity or air supply, is low in cost, has a low failure rate, and is intuitive to operate. It is particularly suitable for small and medium-sized printing equipment or scenarios with low automation requirements, and facilitates quick on-site adjustments.

[0047] like Figures 1-3 As shown, based on the above embodiment, the lifting drive device 220 is configured as an automatic drive device.

[0048] Specifically, the automatic drive device includes: a lifting guide rail, vertically fixed on the fixed base 210; a slider, fixedly connected to the ink tank plate 200 and slidably mounted on the lifting guide rail; a drive motor, mounted on the fixed base 210; and a transmission assembly, connected between the output shaft of the drive motor and the slider, for converting the rotational motion of the motor into the linear lifting motion of the slider; the transmission assembly is one of a lead screw and nut pair, a synchronous belt pulley set, or a gear and rack mechanism.

[0049] In this embodiment, automatic drive (such as motor + lead screw) can realize precise, remote or programmed lifting of ink tank plate 200, linked with the printing roller 100 replacement process, improve changeover efficiency, and is suitable for high-speed, multi-variety printing production lines, reducing manual intervention.

[0050] like Figures 1-3 As shown, based on the above embodiment, it also includes an ink delivery roller 500, which is movably connected to the ink trough plate 200 so that it can be close to or away from the printing roller 100.

[0051] In this embodiment, the position of the inking roller 500 is adjustable, allowing it to dynamically conform to the roller surface according to the diameter change of the printing roller 100, ensuring uniform inking; at the same time, it can be separated when the machine is stopped to avoid dry ink sticking or damage to the roller surface, extend the life of consumables and improve the stability of printing quality.

[0052] like Figures 1-3 As shown, based on the above embodiment, the ink cover plate 300 is provided with a handle 320.

[0053] In this embodiment, the handle 320 provides the operator with a convenient point of force, making it easy to open or close the ink cover 300 by hand, which significantly improves human-machine interaction efficiency and operating comfort, especially when frequently adding ink, cleaning or maintenance.

[0054] like Figures 1-3As shown, in summary, this utility model provides a reasonably structured and highly adaptable ink anti-splatter device, specifically designed to solve the problem of ink splashing along the roller surface and both ends caused by centrifugal force generated during the high-speed rotation of the printing roller 100. By setting up a liftable ink trough plate 200 and an ink cover plate 300 hinged at one end and openable at the other, the relative positions can be flexibly adjusted according to printing rollers 100 with different diameters ranging from Φ120mm to Φ300mm. During operation, the ink cover plate 300 is close to the surface of the printing roller 100, effectively blocking radial splashing; together with the side baffles 400 located at both ends of the printing roller 100, the three together form a semi-enclosed cavity surrounding the lower part and axial sides of the printing roller 100, confining the ink splashed out by centrifugal force within this space and preventing overflow and pollution of equipment and the environment.

[0055] Furthermore, the distal end of the ink cover plate 300 slides in conjunction with the slide rail 411 on the limit frame 410 via the slide rod 310, achieving smooth guidance during the opening and closing process and precise positioning in the closed state; the handle 320 on it facilitates manual operation, significantly improving maintenance convenience. The ink trough plate 200 is supported by the fixed base 210 and its height is adjusted by the lifting drive device 220: either a handwheel + screw type manual drive device can be used to meet the needs of low-cost, high-reliability, and rapid on-site adjustment; or an automatic drive device of motor + guide rail + transmission components can be configured to achieve programmed control linked with the production process. At the same time, the ink delivery roller 500 is movably connected to the ink trough plate 200, dynamically conforming to the roller surface as the diameter of the printing roller 100 changes, ensuring stable ink transfer, and separating when the machine stops to prevent dry ink from sticking together.

[0056] Overall, through the ingenious integration of mechanical structures, this device achieves a unified solution of full-specification compatibility, efficient anti-splashing, convenient maintenance, and intelligent adjustment without the need for complex sealing or additional consumables. It fundamentally solves the "dirty, messy, and poor" problems caused by ink splatter in printing operations, significantly improving equipment cleanliness, operational stability, and user experience. It is especially suitable for modern printing scenarios with multiple varieties and high efficiency.
