Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to an automatic ink fountain cleaning machine for printing presses. Background Technology

[0002] An automatic ink fountain cleaning machine for printing presses is a device used to clean residual ink, oil stains and other impurities in the ink fountain of a printing press. It can automatically complete the cleaning task, thereby improving production efficiency, reducing the time and labor intensity of manual cleaning, and ensuring the cleanliness of the ink, avoiding contamination by different colors or types of ink, and ensuring printing quality. The main function of the ink fountain cleaning machine is to remove ink residue in the ink fountain in a timely manner during the printing process, prevent cross-contamination of colors or blockage of the ink fountain pipes, improve printing quality and extend the life of the equipment. Although automatic ink fountain cleaning machines for printing presses can efficiently complete the cleaning work, there is still a problem that requires manual intervention during the process of feeding the ink fountains into the cleaning machine. Specifically, manually feeding the ink fountains into the cleaning machine has several obvious drawbacks. Since the cleaning machine usually needs to feed the ink fountains one by one, each cleaning requires manual handling. Ink fountains are usually quite heavy, especially in large-scale printing, where the weight and volume of the ink fountains are large. Manually handling and emptying the ink fountains requires a lot of physical strength. At the same time, many printing press ink fountain cleaning machines are designed with a relatively compact space, requiring careful handling during manual handling. This is a problem that urgently needs to be solved. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model provides an automatic ink fountain cleaning machine for printing presses. The design of the automatic cleaning machine frame and cleaning chamber, combined with the operation of the material pushing component, enables the ink fountain components or materials to be efficiently fed into the cleaning chamber for cleaning, avoiding the tediousness of manual operation. The drive cylinder, through the coordinated work of the slide rod, sliding plate and movable rod, can accurately push the material to be cleaned into the cleaning chamber, ensuring the stability and automation of the cleaning process.

[0004] To solve the above technical problems, this utility model provides the following technical solution: an automatic ink fountain cleaning machine for printing presses, comprising an automatic cleaning machine frame, characterized in that: a cleaning chamber is installed on the automatic cleaning machine frame, a drain outlet is provided at the bottom of the cleaning chamber, a feed inlet is connected to the top of the cleaning chamber, a mounting base is installed on the side wall of the feed inlet, a pre-storage box is installed on the upper end of the mounting base, a pushing component is connected inside the pre-storage box, and a disassembly component is installed on the pushing component.

[0005] As a preferred technical solution of this utility model, the pushing assembly includes a support base with its bottom end mounted on the mounting base, a drive cylinder disposed above the support base, a slide rod connected to the output end of the drive cylinder, a slide plate movably connected to the slide rod, a movable rod inserted into the slide plate, a return spring wound around the outer wall of the movable rod, and a push plate fixed to the outer end wall of the movable rod.

[0006] As a preferred technical solution of this utility model, the sliding rods are arranged in three sets in parallel, and each set of sliding rods extends through the outer wall of the pre-storage box and into the interior of the pre-storage box.

[0007] As a preferred technical solution of this utility model, the sliding rods are arranged in three sets in parallel, and each set of sliding rods extends through the outer wall of the pre-storage box and into the interior of the pre-storage box.

[0008] In a preferred embodiment of this utility model, one end of the reset spring is connected to the outer wall of the slide plate, and the other end of the reset spring is connected to the outer wall of the push plate.

[0009] As a preferred technical solution of this utility model, the disassembly assembly includes a threaded rod fixed to the end of the movable rod, a through hole opened in the slide plate and inserted into the threaded rod, a nut threadedly connected to the through hole, and a rotating cap fixed on the nut.

[0010] As a preferred technical solution of this utility model, the area of ​​the end face of the nut and the sliding plate is larger than the cross-sectional area of ​​the through hole, and the outer wall of the rotating cap is provided with anti-slip texture.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are: The design of the automatic cleaning machine frame and cleaning chamber, combined with the operation of the feeding component, enables the ink fountain component or material to be efficiently fed into the cleaning chamber for cleaning, avoiding the tediousness of manual operation. The drive cylinder, through the coordinated work of the slide bar, sliding plate and movable rod, can accurately push the material to be cleaned into the cleaning chamber, ensuring the stability and automation of the cleaning process.

[0012] The return spring of the pusher assembly provides a buffer for the pusher plate, reducing the impact on the material or pusher plate during the pushing process. This effectively avoids damage and wear to the equipment and extends its service life. This buffer design effectively protects the safety of the ink fountain components and avoids malfunctions caused by uneven force on the material or equipment.

[0013] Easy maintenance is another major advantage of this equipment. The design of the disassembly components allows the material pusher assembly to be easily disassembled simply by rotating the rotating cap when the pusher plate is worn or malfunctioning. No special tools are required, which greatly reduces the difficulty and time of maintenance. In particular, the anti-slip textured rotating cap design can improve the friction during manual operation, making it easier to apply force and ensuring that the disassembly process is easier and more efficient.

[0016] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0017] Example: like Figure 1-4 As shown, an automatic ink fountain cleaning machine for printing presses includes an automatic cleaning machine frame 1, a cleaning chamber 2 installed on the automatic cleaning machine frame 1, a drain outlet 3 at the bottom of the cleaning chamber 2, a feed inlet 4 connected to the top of the cleaning chamber 2, a mounting base 5 installed on the side wall of the feed inlet 4, a pre-storage box 6 installed on the upper end of the mounting base 5, a pusher assembly 7 connected inside the pre-storage box 6, and a disassembly assembly 8 installed on the pusher assembly 7. The feeding assembly 7 includes a support base 71 with its bottom end mounted on the mounting base 5, a drive cylinder 72 disposed above the support base 71, a slide rod 73 connected to the output end of the drive cylinder 72, a slide plate 74 movably connected to the slide rod 73, a movable rod 75 inserted into the slide plate 74, a return spring 76 wound around the outer wall of the movable rod 75, and a push plate 77 fixed to the outer end wall of the movable rod 75. The disassembly assembly 8 includes a threaded rod 81 fixed to the end of the movable rod 75, a through hole 82 opened in the slide plate 74 and inserted into the threaded rod 81, a nut 83 threadedly connected to the through hole 82, and a rotating cap 84 fixed on the nut 83; When material needs to be pushed, the drive cylinder 72 installed on the support base 71 is activated. Its output end drives the slide rod 73 connected to it to move horizontally. There are three sets of slide rods 73 arranged in parallel, all of which penetrate the outer wall of the pre-storage box 6 and extend into the interior. They can synchronously drive the slide plate 74 fitted on the slide rod to move. The slide plate 74 is connected to the push plate 77 through the movable rod 75. Therefore, when the slide plate moves, it will directly drive the push plate 77 into the interior of the pre-storage box 6, pushing the ink fountain parts or materials to be cleaned in the box towards the feed port 4, and finally into the cleaning chamber 2. During the material pushing process, the return spring 76 on the outer wall of the movable rod 75 will be compressed due to the resistance generated by the push plate 77 contacting the material, which plays a buffering role and avoids damage to the material or the push plate. After the material pushing is completed, the output end of the drive cylinder 72 retracts, driving the slide rod 73 and the slide plate 74 to move in the opposite direction. At the same time, the return spring 76 releases elastic potential energy and pushes the push plate 77 back to the initial position, preparing for the next material pushing. When the push plate 77 shows signs of wear or malfunction and requires maintenance, simply manually rotate the rotating cap 84 fixed to the nut 83. The anti-slip texture on the outer wall of the rotating cap increases friction, making it easier to apply force. The rotating cap 84 drives the nut 83 to rotate in the opposite direction along the threaded rod 81 until the nut separates from the slide plate 74. At this point, the movable rod 75 can be pulled out from the through hole 82 of the slide plate 74, and the push plate 77, which is fixed to the movable rod, can be removed together, completing the disassembly. No special tools are required throughout the process. After maintenance, align the threaded rod 81 at one end of the movable rod 75 with the slide plate. Insert the through hole 82 of 74 until the push plate 77 returns to its position; then rotate the rotating cap 84 to drive the nut 83 to tighten along the threaded rod until the nut is tightly fitted against the outer wall of the slide plate 74, thus fixing the movable rod and the push plate and completing the installation. The contact surface area between the nut 83 and the slide plate 74 is larger than the cross-sectional area of ​​the through hole 82. This design allows the nut to be firmly stuck on the outside of the slide plate. Even if the movable rod 75 is subjected to a forward thrust during pushing or a spring pull during reset, it will not slip out of the through hole 82, ensuring the structural stability of the pushing assembly during operation.

[0018] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0019] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the utility model as defined by the appended claims and their equivalents.
