Description

Technical Field

[0001] This utility model relates to the field of quality inspection technology in the printing industry, and in particular to a printing paper inspection table. Background Technology

[0002] As a core raw material in the printing industry, printing paper plays a crucial role in carrying various types of information such as text and images. Its quality directly affects the final presentation of printed materials, making visual inspection a vital step to ensure that printing paper meets quality standards. With the help of professional visual inspection equipment, defects such as wrinkles, tears, stains, and fiber agglomerations can be accurately detected.

[0003] In the inspection of printed paper, ensuring the stability of the paper during inspection is fundamental to obtaining accurate results. This requires the use of fixing components to effectively secure the paper. However, most existing printed paper inspection devices rely on manual operation for their fixing components. Manual fixing is not only labor-intensive but also extremely inefficient. In large-scale printed paper inspection, manually fixing each sheet individually increases labor intensity and is prone to inconsistent fixing results due to human factors, thus affecting the accuracy and reliability of the inspection results. Furthermore, the inefficiency of manual operation limits the overall inspection progress, making it difficult to meet the demands of the modern printing industry for efficient and precise production processes. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a printing paper inspection table, which solves the problem that most of the fixing components in existing printing paper inspection devices rely on manual operation. Manual fixing is not only labor-intensive but also extremely inefficient.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a printing paper inspection table, including a base, a rotating cylinder and a support frame mounted on the base via an installation groove, an illumination component mounted on the support frame, a drive motor mounted on the base, the drive motor connected to the rotating cylinder via a rotation mechanism, a placement platform mounted on the rotating cylinder via a fixed frame, a placement groove on the upper surface of the placement platform, a pick-and-place opening on the placement platform, a positioning plate above the placement groove, a reciprocating screw shared by the placement platform and the fixed frame, the reciprocating screw cooperating with the base via a transmission mechanism, and the positioning plate connected to the reciprocating screw via a lifting mechanism.

[0008] Preferably, the rotating mechanism includes a drive gear mounted on the output shaft of the drive motor, and the rotating cylinder is provided with a gear ring that meshes with the drive gear.

[0009] Preferably, the transmission mechanism includes a transmission gear mounted on the end of a reciprocating lead screw, and the base is provided with a rack corresponding to the transmission gear.

[0010] Preferably, the lifting mechanism includes a lifting frame threaded onto a reciprocating screw, the lifting frame slidingly passing through the placement platform and fixedly connected to the positioning plate.

[0011] Preferably, the vertical cross-section of the mounting groove is inverted T-shaped, and the vertical cross-section of the rotating cylinder is I-shaped.

[0012] Preferably, the plurality of placement platforms are distributed at equal intervals around the base, and the rack is designed in an arc shape.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Through the coordinated operation of the drive motor, rotating mechanism, transmission mechanism, and lifting mechanism, automated operations such as the rotation of the placement platform and the lifting of the positioning plate are achieved. For example, after the drive motor starts, it drives the drive gear to rotate, which in turn drives the rotating cylinder and the placement platform to rotate. During the rotation of the placement platform, the transmission gear meshes with the rack to rotate the reciprocating screw, realizing the automatic pressing down and fixing of the positioning plate and the lifting up and releasing of the fixing, reducing manual operation steps and improving work efficiency.

[0016] 2. The placement table is equipped with a placement slot and a pick-and-place opening, which facilitates the gripping and picking-and-place of printed paper. The positioning plate can press down to fix the paper during inspection and rise to release the fixation after inspection. At the same time, the rotation of the placement table can move the paper to below the lighting component, which is convenient for inspecting the appearance defects of the paper such as wrinkles, damage, stains, and fiber agglomeration, thus improving the accuracy and convenience of inspection.

[0022] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0023] This utility model provides a technical solution:

[0024] Reference Figure 1-4 A printing paper inspection table includes a base 1. A rotating cylinder 3 and a support frame 4 are mounted on the base 1 via a mounting groove 2. A lighting component 5 is mounted on the support frame 4. A drive motor 6 is mounted on the base 1. The drive motor 6 is connected to the rotating cylinder 3 via a rotating mechanism. A placement platform 9 is mounted on the rotating cylinder 3 via a fixed frame 8. A placement groove 10 is provided on the upper surface of the placement platform 9. The placement platform 9 is also provided with a pick-and-place port 11. A positioning plate 12 is provided above the placement groove 10. A reciprocating screw 17 is provided on both the placement platform 9 and the fixed frame 8. The reciprocating screw 17 is connected to the base 1 via a transmission mechanism. The positioning plate 12 is connected to the reciprocating screw 17 via a lifting mechanism.

[0025] The rotating mechanism includes a drive gear 16 mounted on the output shaft of the drive motor 6, and a gear ring 7 on the rotating cylinder 3 that meshes with the drive gear 16. After the drive motor 6 is started, it can drive the drive gear 16 to rotate, and the drive gear 16 can mesh with the gear ring 7 to drive the rotating cylinder 3 to rotate in the mounting groove 2, that is, to rotate on the base 1.

[0026] Preferably, the transmission mechanism includes a transmission gear 14 mounted on the end of the reciprocating lead screw 17, and a rack 15 corresponding to the transmission gear 14 is provided on the base 1. When the transmission gear 14 rotates to a certain position with the placement platform 9 and other components, the transmission gear 14 will mesh with the rack 15. During its subsequent rotation, the transmission gear 14 will continue to rotate under the action of the rack 15.

[0027] The lifting mechanism includes a lifting frame 13 threadedly mounted on a reciprocating screw 17. The lifting frame 13 slides through the placement platform 9 and is fixedly connected to the positioning plate 12. The reciprocating screw 17 is supported by a fixed frame 8, and part of it rotates through the fixed frame 8 and extends below the fixed frame 8. The outer wall of this part is not threaded.

[0028] The vertical cross-section of the mounting groove 2 is inverted T-shaped, while the vertical cross-section of the rotating cylinder 3 is I-shaped. This design prevents the rotating cylinder 3 from moving vertically and detaching from the base 1 and the mounting groove 2.

[0029] Multiple placement platforms 9 are evenly spaced around the base 1, and the rack 15 has an arc-shaped design, specifically in the shape of a quarter-circle.

[0030] In practical use, the working principle of this utility model is as follows:

[0031] The placement slot 10 on the placement table 9 can hold the printed paper to be inspected. The printed paper can be grasped and placed into the placement slot 10 through the pick-and-place port 11, and placed below the positioning plate 12. Then the drive motor 6 starts and rotates slowly. As the drive motor 6 rotates, it can drive the rotating cylinder 3 to rotate in conjunction with the drive gear 16 and the gear ring 7. The rotating cylinder 3 drives the placement table 9 to rotate by the fixed frame 8. As the placement table 9 rotates, the transmission gear 14 on it will mesh with the rack 15. As the placement table 9 continues to rotate, the transmission gear 14 will continue to rotate. At this time, the reciprocating screw 17 will also rotate. Therefore, the lifting frame 13 will drive the positioning plate 12 to move. When the transmission gear 14 is in the middle of the rack 15, the lifting frame 13 will descend to the lowest position. At this time, the positioning plate 12 realizes the downward pressing and fixing of the printed paper to be inspected. At this time, the printed paper to be inspected moves with the placement table 9 to the position directly below the lighting component 5. It can be inspected by relying on the lighting component 5, mainly to check whether there are appearance defects such as wrinkles, damage, stains, and fiber agglomeration.

[0032] After the test is completed, the drive motor 6 starts again, and the transmission gear 14 drives the reciprocating screw 17 to continue to rotate. At this time, the lifting frame 13 will drive the positioning plate 12 to rise, thereby releasing the fixing operation of the printed paper to be tested, making it convenient to remove it later.

[0033] In this solution, there are four placement platforms 9. One is located below the lighting component 5, on which the printed paper to be tested is being tested. The other three placement platforms 9 are as follows: one has been tested, one is waiting to be tested, and one is taking out the printed paper to be tested and putting in the next printed paper to be tested.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
