[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 The present invention provides an upper and lower roller opening and closing assembly for PP board embossing rollers, comprising a main body 1 and a lower roller shaft 2.

[0027] Reference Figure 2 and Figure 3 As shown, a lower roller shaft 2 is provided inside the main body 1, and an upper roller shaft 3 is provided above the lower roller shaft 2. A drive structure 4 is installed on one side of the main body 1. The drive structure 4 includes a drive motor 401 installed on one side of the main body 1, a transmission belt 402 is provided on one side of the drive motor 401, a fixed shaft 403 is provided inside one side of the transmission belt 402, an electric push rod 404 is installed above one side of the transmission belt 402, a mounting plate 405 is provided at the bottom end of the electric push rod 404, and a tension wheel 406 is provided on one side of the mounting plate 405. The lower roller shaft 2 is rotatably connected inside the main body 1. Both sides of the lower roller shaft 2 and the upper roller shaft 3 abut against one side of the transmission belt 402. The tension wheel 406 is rotatably connected on one side of the mounting plate 405. The outer wall of the tension wheel 406 abuts against one side of the transmission belt 402. The lower roller shaft 2 and the upper roller shaft 3 are connected to each other through the transmission belt 402.

[0028] In the process of embossing PP boards, a drive structure 4 is provided to ensure that the two sets of rollers rotate synchronously. This drives the drive motor 401, which in turn causes the transmission belt 402 to drive the lower roller 2 and the upper roller 3 to rotate synchronously inside the main body 1. To prevent the transmission belt 402 from becoming loose during use, a fixed shaft 403 and a tensioning wheel 406 are provided to tighten the transmission belt 402. The electric push rod 404 is activated to push the mounting plate 405 up and down inside the main body 1, thereby changing the tension of the tensioning wheel 406 on the transmission belt 402. This prevents excessive tension on the transmission belt 402 during the adjustment of the upper roller 3, thus avoiding damage to the transmission belt 402 and greatly increasing the practicality of the device.

[0029] Reference Figure 1 , Figure 4 and Figure 5 As shown, the top of the main body 1 is equipped with an opening and closing structure 5. The opening and closing structure 5 includes an adjustment seat 501 installed at the top of the main body 1. A threaded rod 502 is provided inside the adjustment seat 501. A moving block 503 is provided at the bottom end of the threaded rod 502. A threaded sleeve 504 is provided inside the adjustment seat 501 outside the threaded rod 502. An adjustment motor 505 is installed at the top of the adjustment seat 501. An output gear 506 is provided at the bottom end of the adjustment motor 505. The upper roller shaft 3 passes through the interior of the moving block 503 on both sides. The upper roller shaft 3 and the moving block 503 are rotatably connected. The threaded rod 502 and the threaded sleeve 504 are threadedly connected. The threaded sleeve 504 and the output gear 506 mesh with each other.

[0030] During the embossing process of PP boards, it may be necessary to emboss boards of different sizes and thicknesses. A hinged structure 5 is provided, which activates the adjusting motor 505, causing the output gear 506 to rotate inside the adjusting seat 501. The output gear 506 meshes with the threaded sleeve 504, causing them to rotate synchronously. The threaded sleeve 504 is threadedly connected to the threaded rod 502, allowing the threaded rod 502 to move inside the threaded sleeve 504. This, in turn, drives the moving block 503 to move inside the main body 1. The two sides of the upper roller shaft 3 penetrate the interior of the moving block 503 and are rotatably connected to it, facilitating the movement of the upper roller shaft 3 within the main body 1 without significantly affecting its rotation. This greatly increases the practicality of the device.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
