Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of full-automatic printing equipment, in particular to a roller support mechanism of a full-automatic printing machine. Background Art
[0002] Fully automatic printing machines are non-contact inkjet printing devices that utilize advanced inkjet technology to produce photo-quality, full-color prints on a variety of surfaces. They are widely used in packaging, advertising, decoration, and crafts, among other fields.
[0003] The roller support mechanism usually includes key components such as support rods, support seats, bearings, and locking mechanisms. These components work together to ensure that the roller can stably support the receiving air shaft or other rollers in the fully automatic printing press.
[0004] Traditional roller support mechanisms in printing presses often suffer from unstable support due to improper design and material selection. Under prolonged, high-load use, the support mechanism is prone to deformation, wear, and even breakage, affecting roller stability and, in turn, press operation and print quality. Instability can also lead to deviation or jitter in material transport, reducing the accuracy and clarity of printed product registration. Therefore, a roller support mechanism for fully automatic printing presses was proposed to address these issues. Utility Model Content
[0005] To address the shortcomings of existing technologies, traditional roller support mechanisms for printing presses often suffer from unstable support due to improper design and material selection. Under prolonged, high-load use, the support mechanism is prone to deformation, wear, and even breakage, affecting roller stability and, in turn, press operation and print quality. Unstable support can also lead to deviation or jitter in material transfer, reducing the accuracy and clarity of printed product overprinting. This utility model proposes a roller support mechanism for a fully automatic printing press.
[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: a roller support mechanism of a fully automatic printing machine described in the present invention comprises a base; a printing mechanism is fixedly installed on the upper part of the base, a support seat is provided on one side of the feeding end of the printing mechanism and is fixedly installed on the base, a plurality of rollers are arranged in parallel in the support seat, both ends of the rollers are rotatably installed in the support seat through bearings, and the rollers rotate together through a conveyor belt, support plates are fixedly installed on both sides of the upper part of the support seat, sliding holes are provided on the outer sides of the upper ends of the support plates, and limiting rods are fixedly installed inside the sliding holes, a bidirectional screw is provided between the upper ends of the support plates, both ends of the bidirectional screw are rotatably installed in the support plates through bearings, and slide plates are slidably installed on both ends of the bidirectional screw Material toggling mechanism, its both ends are designed to be spirally connected, and its upper end is provided with a cylinder pressure, and the lower end of the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.
[0007] Preferably, a first motor is fixedly installed on the outer side of the upper end of the support plate, and the rotating shaft of the first motor is fixedly connected to one end of the rotating shaft of the bidirectional screw. By fixedly connecting the rotating shaft of the first motor to one end of the rotating shaft of the bidirectional screw, precise control of the bidirectional screw is achieved.
[0008] Preferably, springs are provided on the upper parts of both ends of the mounting plate, and the springs are slidably mounted on the upper ends of the limiting rods. By providing the springs and making them slidably mounted on the upper ends of the limiting rods, additional buffering and stabilizing effects are provided for the roller support mechanism.
[0009] Preferably, a bidirectional cylinder is fixedly installed at the bottom of the mounting plate, and the piston rod of the bidirectional cylinder is fixedly connected to the two slides respectively. By fixing the bidirectional cylinder at the bottom of the mounting plate and fixing the cylinder piston rod to the two slides respectively, fast and precise adjustment of the roller seat and the rotating roller is achieved.
[0010] Preferably, baffles are provided on both sides of the upper part of the conveyor belt, and the baffles are fixedly mounted on the lower end of the slide. By providing the baffles and fixing them on the lower end of the slide, the material can be effectively prevented from being deflected or falling during the transmission process.
[0011] Preferably, one end of the roller passes through the support seat and is fixedly installed with a rotating wheel. A second motor is provided below the rotating wheel and is fixedly installed on the base. A transmission wheel is fixedly installed on the rotating shaft of the second motor. The transmission wheel and the rotating wheel rotate in coordination through a belt. By passing the support seat through one end of the roller and fixing the rotating wheel, while fixing the second motor on the base and fixing the transmission wheel on the rotating shaft of the motor, the transmission wheel and the rotating wheel are connected by a belt, thereby achieving continuous and stable driving of the roller.
[0012] The utility model is beneficial in that:
[0013] 1. This utility model utilizes a fully automatic printing press to print paper. After a worker places paper on a conveyor belt, the second motor is activated to rotate the roller, which in turn rotates the conveyor belt, which in turn drives the paper toward the printing mechanism. During this process, the first motor and bidirectional cylinder are simultaneously activated, causing the first motor to rotate the bidirectional screw, which, via a slide plate, moves the baffles so that the distance between the baffles is equal to the paper width. The piston rods at both ends of the bidirectional cylinder push the slide to move within the slide rails, which, via a connecting rod, raise and lower the roller seat, adjusting the pressure between the rotating roller and the conveyor belt to ensure paper passage without damaging it. This structural design achieves precise adjustment, stable support, and smooth transmission of the roller support mechanism, resolving the problem of unstable support in conventional printing press roller support mechanisms, often caused by improper design and material selection. Under prolonged, high-load use, the support mechanism is prone to deformation, wear, or even breakage, affecting roller stability and, in turn, press operation and print quality. Unstable support can also lead to material transmission deviation or jumping, reducing the overprint accuracy and clarity of printed products. It improves the adaptability, flexibility, stability and durability of the equipment, and brings significant technological progress and economic benefits to the printing industry.
