Description

Technical Field

[0001] This utility model relates to the technical field of paper output equipment for printing presses, specifically a paper output device for printing presses. Background Technology

[0002] With the development of technology, printed materials have become deeply integrated into daily life and production activities, with printing paper accounting for a large proportion of applications. The choice of paper type mainly depends on two key factors: the specific characteristics of the pre-printed material and the type of printing press used. For example, when printing commonly used reference books such as dictionaries, encyclopedias, and manuals, thin, highly opaque dictionary paper or thin letterpress paper is usually chosen; while offset printing paper or letterpress printing paper is often used for printing general books. In this process, the printing press, as the core equipment, undertakes the main printing tasks.

[0003] According to the search, the paper feeding mechanism of a printing equipment is disclosed in the announcement number CN221295488U. The application describes a paper feeding mechanism that uses a motor to drive the paper feed rollers to rotate. When the paper feed rollers rotate, the paper at the bottom is fed out of the paper box through rotation.

[0004] However, this existing technology has significant shortcomings: when the motor is running continuously, paper is fed out continuously. This operating mode easily leads to paper stacking and jamming at the output nozzle, which in turn interferes with or even interrupts the normal operation of subsequent printing presses. Operators have to frequently and manually start and stop the motor to control the amount of paper fed per cycle. This not only increases the labor intensity of the operators but also significantly reduces the automation level of the equipment and the overall production efficiency, making it difficult to meet the actual needs of modern high-efficiency printing production. Utility Model Content The purpose of this invention is to provide a paper output device for a printing press to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a paper output device for a printing press, comprising a paper box, a connecting roller rotatably connected to the inner wall of the paper box, a rotating roller rotatably connected to the inner wall of the paper box, a paper output port opened on the right side of the paper box, and a paper output component and an adjustment component provided on the outer surface of the paper box. The paper output assembly includes: A cylinder is used to drive the rotating rollers to rotate synchronously. Gear 1 is used to drive the cylinder in one direction. Transmission components are used to provide driving force.

[0006] Preferably, the cylinder is fixed to the outer surface of the rotating roller, and the end of the cylinder away from the rotating roller passes through the paper box, and the cylinder is rotatably connected to the paper box. A gear one is rotatably connected to the outer surface of the paper box, and the cylinder passes through the gear one. A gear two is rotatably connected to the outer surface of the paper box, and the gear one meshes with the gear two. A rack is slidably connected to the outer surface of the paper box, and the rack meshes with the gear two. When the rack moves back and forth, it drives the gear two and the gear one to rotate synchronously back and forth. When the gear one rotates forward, it drives the cylinder and the rotating roller to rotate forward through the ratchet and pawl mechanism, pushing the paper out from the paper outlet. When the gear one rotates in reverse, the ratchet and pawl act to keep the cylinder and the rotating roller stationary, realizing intermittent paper output.

[0007] Preferably, the transmission component includes a motor, which is fixed to the top of the carton via a mounting bracket. A circular plate is fixed to the bottom of the output shaft of the motor, and a circular rod is mounted on the bottom of the circular plate. The outer surface of the circular rod abuts against a connecting rod, and the bottom of the connecting rod is fixed to the top of the rack. When the motor is started, the circular rod rotates accordingly, and its outer surface contacts the inner side of the connecting rod, driving the connecting rod and the rack to reciprocate.

[0008] Preferably, the adjusting component includes a groove formed at the bottom of the circular plate. A slider is slidably connected to the inner wall of the groove, and a screw is rotatably connected to the inner wall of the groove. A second motor is fixed to the inner wall of the groove, and the output shaft of the second motor is fixed to the outer surface of the screw. The screw passes through the slider and is threadedly connected to the slider. Controlling the second motor to drive the screw to rotate adjusts the distance between the slider and the center of the circular plate. Changing the travel of the connecting rod controls the number of rotations of gear one and gear two, adapting to the paper output requirements of different paper lengths and facilitating adjustment.

[0009] Preferably, the outer surface of the cardboard box is equipped with a door, the inner wall of the cardboard box is slidably connected to a tray, the bottom of the tray is fixed with a slide rod, the bottom of the slide rod passes through the cardboard box, the slide rod is slidably connected to the cardboard box, the bottom of the tray is fixed with a spring, the bottom of the spring is fixed to the bottom of the inner wall of the cardboard box, and through the spring, the paper is always in contact with the outer surface of the connecting roller and the rotating roller.

[0010] Preferably, a pawl is installed on the outer surface of the cylinder, and a ratchet is installed on the inner wall of the gear, so that the cylinder and the roller can only rotate forward and not in reverse.

[0011] Preferably, a rubber pad is fixed to the outer surface of the roller to facilitate increased friction.

[0012] Compared with the prior art, the present invention provides a paper output device for a printing press, which has the following advantages: 1. The paper output device of this printing press, through the set paper output assembly, after starting motor one, the round rod rotates and drives the connecting rod and rack to reciprocate through contact, thereby causing gear two and gear one to reciprocate synchronously. When gear one rotates forward, it drives the cylinder and the rotating roller to rotate forward through the ratchet and pawl mechanism to realize automatic paper output; when it rotates in reverse, it prevents the cylinder from rotating and stops the rotating roller, thereby realizing intermittent paper output and preventing paper backflow, without the need to repeatedly start and stop motor one.

[0013] 2. The paper output device of this printing press controls the position of the adjustable slider of motor 2 through the set adjustment component, thereby changing the stroke of the connecting rod, and thus controlling the rotation of gear 1 and gear 2 to adapt to the paper output requirements of different paper lengths.

Detailed Implementation

[0016] like Figures 1-5 As shown, this utility model provides a technical solution: a paper output device for a printing press, including a paper box 1, a connecting roller 3 rotatably connected to the inner wall of the paper box 1, a rotating roller 10 rotatably connected to the inner wall of the paper box 1, a paper output port 4 opened on the right side of the paper box 1, and a paper output assembly 8 and an adjustment assembly 9 provided on the outer surface of the paper box 1; the paper output assembly 8 includes: a cylinder 80, a first gear 81, a second gear 82, a rack 83, a transmission component 84, a first motor 840, a round rod 841, a connecting rod 842, and a round plate 844.

[0017] A cylinder 80 is fixed to the outer surface of the roller 10. One end of the cylinder 80, away from the roller 10, passes through the cardboard box 1, and the cylinder 80 is rotatably connected to the cardboard box 1. A gear 81 is rotatably connected to the outer surface of the cardboard box 1, and the cylinder 80 passes through the gear 81. A gear 82 is rotatably connected to the outer surface of the cardboard box 1, and gears 81 and 82 mesh. A rack 83 is slidably connected to the outer surface of the cardboard box 1, and the rack 83 meshes with gear 82. The transmission component 84 includes a motor 840, which is mounted via... The frame is fixed on the top of the cardboard box 1. A circular plate 844 is fixed at the bottom of the output shaft of motor 840. A circular rod 841 is installed at the bottom of the circular plate 844. The outer surface of the circular rod 841 abuts against the connecting rod 842. The bottom of the connecting rod 842 is fixed to the top of the rack 83. A pawl is installed on the outer surface of the cylinder 80. A ratchet is installed on the inner wall of the gear 81. After motor 840 is started, the circular rod 841 rotates and its outer surface contacts the inner side of the connecting rod 842, driving the connecting rod 842 and the rack 83 to reciprocate. The rack 83 drives the second gear 82 and the first gear 81 to reciprocate synchronously: when the first gear 81 rotates forward, it drives the cylinder 80 and the roller 10 to rotate forward through the ratchet and pawl mechanism, pushing the paper out from the paper outlet 4 to achieve automatic paper output; when the first gear 81 rotates in reverse, the ratchet and pawl act to prevent the cylinder 80 from rotating and the roller 10 from moving, thereby achieving intermittent paper output and effectively preventing paper from being pulled back.

[0018] The adjusting component 9 includes a groove 90 located at the bottom of the circular plate 844. A slider 92 is slidably connected to the inner wall of the groove 90, and a screw 91 is rotatably connected to the inner wall of the groove 90. A second motor 93 is fixed to the inner wall of the groove 90, and the output shaft of the second motor 93 is fixed to the outer surface of the screw 91. The screw 91 passes through the slider 92 and is threadedly connected to the slider 92. Controlling the second motor 93 can drive the screw 91 to rotate, thereby adjusting the distance between the slider 92 and the center of the circular plate 844. This adjustment can change the travel of the connecting rod 842, thereby controlling the number of rotations of gear 1 81 and gear 2 82 to adapt to the paper output requirements of different paper lengths.

[0019] A door 2 is installed on the outer surface of the cardboard box 1. A tray 5 is slidably connected to the inner wall of the cardboard box 1. A slide rod 6 is fixed to the bottom of the tray 5, and the bottom of the slide rod 6 passes through the cardboard box 1. The slide rod 6 is slidably connected to the cardboard box 1. A spring 7 is fixed to the bottom of the tray 5, and the bottom of the spring 7 is fixed to the bottom of the inner wall of the cardboard box 1. Through the spring 7, the paper is always in contact with the outer surface of the connecting roller 3 and the rotating roller 10, which facilitates the paper feeding process. A rubber pad is fixed to the outer surface of the rotating roller 10 to increase friction and prevent the rotating roller 10 from slipping on the paper.

[0020] In use, the stacked paper is placed on top of the tray 5, so that the top of the paper is in contact with the outer surface of the connecting roller 3 and the rotating roller 10. At the same time, the paper outlet 4 is aligned with the paper inlet of the printing press. Then, the motor 840 is turned on, and the round rod 841 rotates synchronously. The outer surface of the round rod 841 abuts against the inner side of the connecting rod 842, which drives the connecting rod 842 and the rack 83 to move back and forth. This drives the gear 82 and the gear 81 to rotate synchronously back and forth. When the gear 81 rotates forward, it drives the cylinder 80 and the rotating roller 10 to rotate forward through the ratchet and pawl. At this time, the rotating roller 10 drives the paper to be discharged from the paper outlet 4, thus realizing automatic paper output. When gear 81 reverses, the ratchet and pawl prevent cylinder 80 from rotating, thus preventing roller 10 from rotating and enabling intermittent paper feeding. This also prevents paper from being carried back. Meanwhile, spring 7 ensures that the paper remains in contact with the outer surfaces of connecting roller 3 and roller 10, facilitating paper feeding. When dealing with paper of different lengths, motor 93 is controlled to rotate screw 91, thereby controlling the distance between slider 92 and the center of circular plate 844. This adjusts the movement distance of connecting rod 842 and the number of rotations of gear 81 and gear 82, adapting to paper feeding of different lengths.

[0021] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
