Description

Technical Field

[0001] This application relates to the field of printing technology, and in particular to a printing conveying and leveling mechanism. Background Technology

[0002] A printing press is a machine for printing text and images. Modern printing presses generally consist of mechanisms for plate mounting, inking, impression, and paper feeding. Its principle is to first create a printing plate containing the text or image to be printed, mount it on the printing press, and then apply ink, either manually or through the press, to the areas on the printing plate containing the text and image. The ink is then directly or indirectly transferred to paper or other substrates. Currently, during printing, wrinkles in the paper itself and tilting during paper transport can affect the printing quality. Therefore, a printing conveyor leveling mechanism is proposed. Utility Model Content

[0003] To address the issues of paper wrinkles and tilting during transport, this application provides a printing conveying leveling mechanism.

[0004] The printing conveying and leveling mechanism provided in this application adopts the following technical solution:

[0005] A printing conveying and leveling mechanism includes a frame, on which a conveying mechanism and a paper pressing mechanism are mounted. The paper pressing mechanism is located at the end of the conveying mechanism in the direction of movement. A baffle is mounted on the frame and is located on the conveying plane of the conveying mechanism. The baffle is connected to the frame via a moving mechanism and can move in a direction perpendicular to the conveying plane. Detectors are mounted on both sides of the baffle and can detect the tilt of the paper.

[0006] Preferably, the moving mechanism includes a bracket fixedly mounted on a frame, a vertical rod fixedly connected to the upper surface of the bracket, the upper end of the vertical rod being slidably connected to the bracket, and a spring sleeved on the vertical rod. A first electromagnet is fixedly connected to the upper surface of the baffle, and a second electromagnet is fixedly connected to the bracket. When the first electromagnet and the second electromagnet are energized, they attract each other, causing the baffle to move upward.

[0007] Preferably, the detector is provided in two sets and is symmetrically arranged on both sides of the bracket.

[0008] Preferably, the conveying mechanism includes conveyor rollers rotatably mounted on both sides of the frame, with conveyor belts fitted onto the surfaces of the two sets of conveyor rollers, and a motor fixedly mounted on the surface of the frame, with the output shaft of the motor fixedly connected to the left conveyor roller.

[0009] Preferably, a paper pressing roller is rotatably connected to the frame, and the paper pressing roller is located above the conveyor roller on the right side.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] This invention, by setting up baffles, a moving mechanism, and paper pressing rollers, can remove wrinkles on the surface of paper, flatten the paper, and straighten the paper so that it can be printed normally, ensuring the printing quality. Attached Figure Description

[0016] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0017] This application discloses a printing conveying and leveling mechanism, including a frame 1. The frame 1 is provided with a conveying mechanism and a paper pressing mechanism. The paper pressing mechanism is located at the end of the moving direction of the conveying mechanism. A baffle 9 is provided on the frame 1. The baffle 9 is located on the conveying plane of the conveying mechanism and is connected to the frame 1 through a moving mechanism. The baffle 9 can move in a direction perpendicular to the conveying plane. Detectors 11 are provided on both sides of the baffle 9. The detectors 11 can detect the tilt of the paper.

[0018] Furthermore, the conveying mechanism includes conveyor rollers 2 rotatably mounted on both sides of the frame 1, conveyor belts 4 are sleeved on the surfaces of the two sets of conveyor rollers 2, and a motor 3 is fixedly mounted on the surface of the frame 1. The output shaft of the motor 3 is fixedly connected to the conveyor roller 2 on the left side.

[0019] Furthermore, a paper pressure roller 6 is rotatably connected to the frame 1, and the paper pressure roller 6 is located above the right-side conveyor roller 2.

[0020] Furthermore, the detector 11 is provided in two sets, and is symmetrically arranged on both sides of the bracket 5.

[0021] In this embodiment, the paper is placed on the surface of the conveyor belt 4 by driving the conveyor roller 2 and the conveyor belt 4 through the drive motor 3, and the paper can be transported.

[0022] In this embodiment, by setting up a baffle 9 and a detector 11 in cooperation, the baffle 9 is located on the conveying plane, that is, the upper surface of the conveyor belt 4, which can limit the paper and straighten the tilted paper during transportation. It should be noted that the detector 11 and the moving mechanism can be used with a controller. The detector 11 can be a camera device. When both detectors 11 on both sides capture the paper, the detector 11 can send a signal to the controller. The controller controls the moving mechanism to move, driving the baffle 9 to move upward, and the conveying mechanism can continue to transport the straightened paper. By setting up a paper pressure roller 6, the paper pressure roller 6 can smooth out the wrinkles of the paper when the paper passes by. Therefore, this utility model can remove the wrinkles on the surface of the paper, flatten the paper, and straighten the paper to ensure that the paper can be printed normally.

[0023] Specifically, the controller can be a microcontroller. A microcontroller consists of an arithmetic logic unit (ALU), memory, input / output devices, etc., essentially functioning as a miniature computer. Compared to general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency and cost savings. Its biggest advantage is its small size, allowing it to be placed inside the instrument, but it has limited storage capacity, simple input / output interfaces, and low power consumption. In this embodiment, the specific model of the microcontroller is not required.

[0024] Furthermore, the moving mechanism includes a bracket 5 fixedly installed on the frame 1, a vertical rod 8 fixedly connected to the upper surface of the bracket 5, the upper end of the vertical rod 8 being slidably connected to the bracket 5, and a spring 12 being sleeved on the vertical rod 8. A first electromagnet 7 is fixedly connected to the upper surface of the baffle 9, and a second electromagnet 10 is fixedly connected to the bracket 5. When the first electromagnet 7 and the second electromagnet 10 are energized, they attract each other, causing the baffle 9 to move upward.

[0025] In this embodiment, the controller can connect the power supply of the first electromagnet 7 and the second electromagnet 10, so that the first electromagnet 7 and the second electromagnet 10 attract each other, and the baffle 9 moves upward. The aligned paper can then follow the conveyor belt 4 and pass under the baffle 9. During the upward movement of the baffle 9, the spring 12 is compressed. After the paper has passed through the baffle 9, the controller disconnects the power supply of the first electromagnet 7 and the second electromagnet 10. The spring 12 extends and drives the baffle 9 to reset, so that the baffle 9 can then be aligned with the subsequent paper.
