Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a paper correction device for printing presses. Background Technology

[0002] During continuous printing, paper needs to be fed to the printing press continuously. In order to prevent the paper from shifting during the paper feeding process, the staff usually use the printing press paper correction device to correct the paper and ensure the quality of the paper printing. The existing printing press paper correction device usually consists of a conveyor belt and a correction plate.

[0003] For example, utility model application CN201922071497.7 discloses a paper correction device for adjusting the paper transport direction on a printing press. Specifically, it includes a base frame, two sets of conveying mechanisms for conveying paper, an adjusting mechanism for adjusting the distance between the two sets of conveying mechanisms, and two sets of correction mechanisms for adjusting the paper transport direction. The correction mechanism includes a correction plate, two correction rollers, and a correction motor for driving the two correction rollers. The correction plate is flush with the upper conveyor belt. The correction rollers are driven by the correction motor and are in contact with each other. The angle between the movement direction of the correction rollers at the contact point with the correction plate and the transport direction of the conveyor belt is an acute angle. The purpose of this utility model is to provide a paper correction device for adjusting the paper transport direction on a printing press.

[0004] However, in terms of current traditional printing press paper alignment devices, existing devices mostly rely on alignment plates to limit the paper during transmission in order to correct the paper's transmission direction. However, during the limiting process, the alignment plate is often in close contact with the paper. As the paper continues to be transmitted, friction is easily generated between the two. This friction not only easily causes the paper to wrinkle, affecting the subsequent printing quality, but also generates static electricity. Static electricity will cause a slight attraction between the alignment plate and the paper, resulting in uneven force on the paper during transmission, which in turn aggravates paper wrinkling, causes edge wear, and in severe cases, paper jamming, making it quite inconvenient to use. Utility Model Content

[0005] In view of this, the present invention provides a paper correction device for a printing press, which has a rubber impact block that can reduce the frictional resistance and static electricity between the correction plate and the paper. By starting the control motor, the control motor drives the first bevel gear to rotate. As the first bevel gear rotates, it drives the second bevel gear that meshes with it to rotate. The rotation of the second bevel gear drives the control shaft to rotate. As the control shaft rotates, it drives the transmission sleeve to rotate. Subsequently, through a series of transmissions, the connecting rocker arm swings back and forth. As the connecting rocker arm swings back and forth, the rubber impact block intermittently impacts the sliding frame, causing the sliding frame to vibrate. Through the transmission of the sliding frame, the correction plate vibrates.

[0006] This utility model provides a paper correction device for a printing press, specifically including: a paper conveyor belt; a support frame fixedly connected to the front of the top end of the paper conveyor belt; a drive motor bolted to the upper left end of the support frame; a mounting frame fixedly connected to the rear end of the support frame; two sliding frames symmetrically slidably connected inside the mounting frame; a control shaft rotatably connected inside the mounting frame; two transmission sleeves symmetrically slidably connected to the outside of the control shaft; both transmission sleeves are disposed inside the mounting frame; two control sliders symmetrically slidably connected inside the support frame; a connecting frame fixedly connected to the bottom end of each of the two control sliders; and correction plates fixedly connected to the inner sides of each of the two connecting frames.

[0007] Optionally, a double-ended screw is coaxially fixedly connected to the right side of the drive motor shaft; the threads at both ends of the double-ended screw have opposite directions; the double-ended screw is rotatably connected inside the support frame; two control sliders are symmetrically threaded to the outside of the double-ended screw; and wear-resistant pads are fixedly connected to the inner sides of both correction plates.

[0008] Optionally, a control motor is bolted to the center of the top surface of the mounting bracket; a first bevel gear is coaxially fixed to the end of the control motor shaft; a second bevel gear is coaxially fixed to the outside of the control shaft; the second bevel gear meshes with the first bevel gear.

[0009] Optionally, the front ends of the two sliding frames are fixedly connected to the rear ends of the two connecting frames; the two transmission sleeves are rotatably connected to the two sliding frames; the ends of the two transmission sleeves are coaxially fixedly connected to a first pulley; the two first pulleys are respectively disposed in the two sliding frames; a second pulley is rotatably connected to the lower part of each of the two sliding frames; the two second pulleys are respectively connected to the two first pulleys through transmission belts.

[0010] Optionally, a control cam is coaxially fixedly connected to the inner side of each of the two second pulleys; two control slides are symmetrically slidably connected inside the two slides; a set of control springs is fixedly connected to the outside of each of the two control slides; the ends of the two sets of control springs are respectively fixedly connected inside the two slides; the positions of the two control slides are aligned with the positions of the two control cams.

[0011] Optionally, each of the two control carriages is hinged to a control link at its end; each of the two carriages is rotatably connected to a connecting rocker arm; the ends of the two control links are respectively hinged to the ends of the two connecting rocker arms; each of the ends of the two connecting rocker arms is fixedly connected to a rubber impact block; each of the rear end faces of the two carriages is fixedly connected to a buffer pad; and the positions of the two rubber impact blocks are aligned with the positions of the two buffer pads. Beneficial effects

[0012] This invention, when correcting paper during transport, activates a control motor, causing a first bevel gear to drive a meshing second bevel gear, which in turn rotates a transmission sleeve. A series of transmissions then cause the control slide to reciprocate, which in turn drives a connecting rocker arm to swing back and forth via a control linkage. As the connecting rocker arm swings, rubber impact blocks intermittently strike the slide, causing it to vibrate. This vibration, transmitted through the slide, vibrates the correction plate. The vibration changes the continuous contact between the correction plate and the paper into intermittent contact, significantly reducing frictional resistance and preventing the paper from being scratched, wrinkled, or torn during correction. Simultaneously, the vibration slightly separates stacked papers, reducing friction and making it easier to adjust their position. The vibration also dynamically addresses paper misalignment caused by uneven material properties and tension fluctuations, helping the paper quickly return to alignment and reducing image misalignment during printing. Furthermore, the slight disturbance from the vibration neutralizes static electricity on the paper surface, reducing paper jams caused by static adsorption. This effectively improves the practicality of the printing press paper correction device and makes it more convenient to use. Attached Figure Description

[0024] A double-ended screw 103 is coaxially fixedly connected to the right side of the drive motor 102 shaft; the threads at both ends of the double-ended screw 103 are in opposite directions; the double-ended screw 103 is rotatably connected inside the support frame 101; two control sliders 104 are symmetrically threaded to the outside of the double-ended screw 103; wear-resistant pads 107 are fixedly connected to the inner sides of the two correction plates 106.

[0028] The specific usage and function of this embodiment: Paper is transported via paper conveyor belt 1 to the printing process for printing. By starting the drive motor 102, the double-headed screw 103 rotates. The rotation of the double-headed screw 103 causes two control sliders 104 to move simultaneously. The movement of the control sliders 104 causes the connecting frame 105 to move, adjusting the spacing between the correction plates 106. This allows the correction plates 106 to correct paper widths of different sizes. The wear-resistant pads 107 reduce friction damage between the correction plates 106 and the paper.

The rotation of the second bevel gear 113... The control shaft 112 will rotate, and the rotation of the control shaft 112 will drive the transmission sleeve 114 to rotate. During the movement of the connecting frame 105, the transmission sleeve 114 will slide along the control shaft 112 through the sliding frame 109. During the rotation of the transmission sleeve 114, the first pulley 115 will rotate. As the first pulley 115 rotates, the second pulley 116 will rotate through the transmission belt. During the rotation of the second pulley 116, the control cam 117 will rotate. As the control cam 117 rotates, it will intermittently press the control slide 118, causing the control slide 118 to slide within the sliding frame 109 and press the control spring 119. When the control slide 118 loses the pressure of the control cam 117, it will reset with the rebound of the control spring 119. Then, through the cooperation of the control cam 117 and the control spring 119, the control slide 118 will reciprocate. Example 2

[0030] The specific usage and function of this embodiment are as follows: During the reciprocating movement of the slide 118, the connecting rod 120 drives the connecting swing rod 121 to swing back and forth. As the connecting swing rod 121 swings back and forth, the rubber impact block 122 intermittently impacts the slide 109, causing the slide 109 to vibrate. The vibration is then transmitted through the slide 109 to the correction plate 106. The buffer pad 123 reduces the impact on the slide 109 and prevents damage to the slide 109.
