Description

Technical Field

[0001] This utility model relates to a stabilizing device, particularly a high-speed conveyor belt stabilizing device for printing presses, and belongs to the field of mechanical design and manufacturing technology. Background Technology

[0002] Gravure printing presses are commonly used printing equipment in printing companies. In a gravure printing press, the image areas of the printing plate are recessed, while the non-image areas are flush with the outer circumference of the printing cylinder. During printing, ink is applied to the printing plate, and excess ink is scraped away by a doctor blade, leaving only the ink in the image areas. Subsequently, the printing medium passes through the printing plate, causing the ink to transfer onto the medium under pressure, thus completing the printing process.

[0003] Gravure printing presses typically use high-speed conveyor belts to transport printing media. These high-speed conveyor belts consist of several horizontal rotating rollers and multiple parallel conveyor belts wound between adjacent horizontal rotating rollers. Due to the large gaps between adjacent horizontal rotating rollers, the conveyor belt is often suspended in the air. This not only leads to frequent belt breakage during the transport of printing media but also frequently results in the printing media being crushed by the conveyor belt rings. Once the conveyor belt breaks, the machine must be stopped for disassembly and replacement, which not only affects printing production but also significantly increases maintenance costs. Therefore, it is necessary to improve the existing technology. Summary of the Invention

[0004] To address the problem that high-speed conveyor belts used in existing gravure printing machines frequently break and damage printing media during transport, this invention provides a high-speed conveyor belt stabilization device for printing machines.

[0005] This utility model is achieved through the following technical solution: a high-speed conveyor belt stabilizing device for a printing press, comprising a frame and a crossbeam, a horizontal rotating roller, a conveyor belt, and a pad;

[0006] The frame is provided with several horizontal rotating rollers at intervals. Multiple parallel conveyor belts are wound around each pair of adjacent horizontal rotating rollers. A pad is provided under the multiple parallel conveyor belts between the pairs of adjacent horizontal rotating rollers, so that the pad can slide and engage with the multiple conveyor belts to support the conveyor belts. This allows the conveyor belts to run smoothly during high-speed transport, preventing them from breaking. At the same time, the pad can also support the printing media being transported on the conveyor belts, ensuring that the printing media will not be damaged during transport.

[0007] Furthermore, the length of the pad is adapted to the spacing between two adjacent transverse horizontal rotating rollers, and the width of the pad is adapted to the length of the transverse horizontal rotating rollers, so that the pad can adapt to the width of the printing medium of the printing press.

[0008] Furthermore, the pad is configured as a horizontal plate, the top surface of which is slidably engaged with the bottom surface of the multiple conveyor belts, and the left and right ends of the horizontal plate are configured as downwardly inclined side plates, so that the printing medium can slide smoothly into and out of the pad through the inclined side plates.

[0009] Furthermore, the length of the pad is adapted to the spacing between two adjacent transverse horizontal rotating rollers, and the width of the pad is adapted to the length of the transverse horizontal rotating rollers, so that the pad can adapt to the width of the printing medium of the printing press.

[0010] Furthermore, the pad is fixed to the crossbeam by a mounting bracket below it. The mounting bracket includes multiple longitudinal horizontal bars evenly spaced from left to right at the bottom of the pad, and each longitudinal horizontal bar consists of two segments, front and rear, spaced apart, with a gap between the front and rear longitudinal horizontal bars. The crossbeam is placed at the gap, and the ends of the front and rear longitudinal horizontal bars at the gap are respectively provided with straight bars extending downwards. The straight bars are provided with horizontal screw holes, and locking screws are provided in the horizontal screw holes so that the front and rear longitudinal horizontal bars and the pads on them are fixed to the crossbeam by the locking screws.

[0011] This invention has the following advantages and effects: By using the above-mentioned solution, the conveyor belt is supported by a pad, enabling it to run smoothly during high-speed transport and preventing breakage. Simultaneously, the pad also supports the printing media transported on the conveyor belt, preventing damage during transport. Furthermore, the movable installation method allows the pad to be installed without altering the original structure of the printing press, greatly improving the flexibility of the device and reducing modification costs.
