During adjustment, the movable plate 2 is moved, and the movement of the movable plate 2 drives the first mounting frames 21, the first rotating rod 26 and the first rotating roller 22 to move. The cooperation of the first rotating roller 22 and the second rotating roller 31 embosses the raw material.
[0028] A top plate 4 and a bottom plate 42 are fixedly connected to the top and bottom of the fixed frame 1 near the first rotating roller 22, respectively. A first scraper 41 and a second scraper 43 are fixedly connected to the top plate 4 and the bottom plate 42 on the side close to each other. The second scraper 43 is in contact with the outer periphery of the second rotating roller 31. When the first rotating roller 22 moves to the top, the first rotating roller 22 rotates, and the first scraper 41 can scrape off the dirt on the outer periphery of the first rotating roller 22. When the second rotating roller 31 rotates, the second scraper 43 can scrape off the dirt on the outer periphery of the second rotating roller 31.
[0029] Example 2:
[0030] Please see Figure 1-3 This is the second embodiment of the present invention. Based on the previous embodiment, both the first scraper 41 and the second scraper 43 are elastic. The first scraper 41 and the second scraper 43 are inclined towards the fixed frame 1 at one end close to each other. A receiving box 44 is inserted into the top surface of the bottom plate 42. The elastic setting of the first scraper 41 and the second scraper 43 can better scrape off the impurities and dirt on the first roller 22 and the second roller 31, while avoiding damage to the first roller 22 and the second roller 31. The first scraper 41 and the second scraper 43 are inclined towards the fixed frame 1 at one end close to each other, which can scrape the impurities and dirt into the receiving box 44.
[0031] A material conveying hole 14 is provided in the middle of the fixed frame 1, and a sliding groove 13 is provided at the top of the material conveying hole 14. A slider 24 is slidably connected inside the sliding groove 13. The side wall of the slider 24 is fixedly connected to the side wall of the moving plate 2. A lead screw 25 is rotatably provided in the middle of the fixed frame 1. A threaded hole is provided in the middle of the fixed frame 1. The lead screw 25 is connected to the threaded hole and is rotatably connected to the top of the slider 24. The material conveying hole 14 helps to convey materials. When the moving plate 2 needs to be adjusted, the lead screw 25 is rotated. The rotation of the lead screw 25 drives the slider 24 to move in the sliding groove 13. The movement of the slider 24 drives the moving plate 2 to move.
[0032] A first fixing plate 11 and a second fixing plate 12 are fixedly connected to the top and bottom of the fixing frame 1 near the first rotating roller 22, respectively. A motor 5 is fixedly connected to the top surface of the first fixing plate 11. A rotating shaft 51 is rotatably arranged between the first fixing plate 11 and the second fixing plate 12. The top end of the rotating shaft 51 passes through the first fixing plate 11 and is fixedly connected to the rotating shaft of the motor 5. When the motor 5 is turned on, the motor 5 drives the rotating shaft 51 to rotate. The first fixing plate 11 and the second fixing plate 12 assist the rotating shaft 51 to rotate and at the same time help to fix the motor 5.
[0033] A first bevel gear 52 is fixedly connected to the outer periphery of the bottom of the rotating shaft 51, and a second bevel gear 53 is fixedly connected to one end of the second rotating rod 32. The second bevel gear 53 meshes with the first bevel gear 52. The rotation of the rotating shaft 51 drives the first bevel gear 52 to rotate, the rotation of the first bevel gear 52 drives the second bevel gear 53 to rotate, and the rotation of the second bevel gear 53 drives the second rotating rod 32 to rotate.
[0034] Two limiting strips 57 are fixedly connected to the top of the outer periphery of the rotating shaft 51. A third bevel gear 55 is provided on the outer periphery of the rotating shaft 51. A rotating ring 58 is fixedly connected to the top of the third bevel gear 55. Both the rotating ring 58 and the third bevel gear 55 are slidably connected to the limiting strips 57. A connecting frame 23 is fixedly connected to one side of the moving plate 2. A fixing ring 54 is fixedly connected to the end of the connecting frame 23. The fixing ring 54 is rotatably connected to the rotating ring 58. A fourth bevel gear 56 is fixedly connected to one end of the first rotating rod 26. The fourth bevel gear 56 is meshed with the third bevel gear 55. The limiting strips 57 help to limit the third bevel gear 55 and the fixing ring 54, ensuring the normal rotation of the fixing ring 54 and the third bevel gear 55. The moving plate 2 is connected to the fixing ring 54 through the connecting frame 23, so that the third bevel gear 55 and the rotating ring 58 are adjusted synchronously when the moving plate 2 is adjusted. The rotation of the rotating shaft 51 drives the limiting strips 57 to rotate, and the rotation of the limiting strips 57 drives the third bevel gear 55 and the rotating ring 58 to rotate.
[0035] In use, the distance between the first rotating roller 22 and the second rotating roller 31 is adjusted according to the raw materials produced. During adjustment, the lead screw 25 is rotated, which drives the slider 24 to move within the slide groove 13. The movement of the slider 24 drives the moving plate 2 to move, which in turn drives the first mounting bracket 21 to move. The movement of the first mounting bracket 21 drives the first rotating rod 26 and the fourth bevel gear 56 to move. The movement of the first rotating rod 26 drives the first rotating roller 22 to move closer to the second rotating roller 31. Simultaneously, the movement of the moving plate 2 drives the connecting bracket 23 to move, which in turn drives the fixing ring 54 to move. The fixing ring 54 drives the third bevel gear 55 and the rotating ring 58 to move on the limiting strip 57, thus adjusting to the appropriate position. Afterwards, the raw material is placed between the first rotating roller 22 and the second rotating roller 31. The motor 5 is turned on, and the motor 5 drives the rotating shaft 51 to rotate. The rotation of the rotating shaft 51 drives the first bevel gear 52 to rotate, which in turn drives the second bevel gear 53 to rotate. The rotation of the second bevel gear 53 drives the second rotating rod 32 to rotate, which in turn drives the second rotating roller 31 to rotate. At the same time, the rotation of the rotating shaft 51 drives the limiting strip 57 to rotate, which in turn drives the third bevel gear 55 and the rotating ring 58 to rotate. The rotation of the third bevel gear 55 drives the fourth bevel gear 56 to rotate, which in turn drives the first rotating rod 26 to rotate, which in turn drives the first rotating roller 22 to rotate. The first roller 22 and the second roller 31 rotate synchronously to emboss the raw material. Synchronous rotation reduces material deviation and improves processing accuracy. The embossed raw material moves to the designated location through the feed hole 14. While the second roller 31 rotates, the second scraper 43 scrapes the outer circumference of the second roller 31 to remove impurities and dirt. After the work is completed, the first roller 22 is moved to the initial top, and the first roller 22 contacts the first scraper 41 at the top. At this time, the first roller 22 is rotated, and the first scraper 41 scrapes off the impurities and dirt. The scraped impurities and dirt fall into the receiving box 44. After the work is completed, the worker pulls out the receiving box 44 for cleaning. In this new invention, the spacing between the first roller 22 and the second roller 31 can be adjusted according to the thickness of the raw material or the depth of the embossing, through the cooperation of the components. This facilitates the production needs of different types of cork paper, making it highly adaptable. During embossing, the first roller 22 and the second roller 31 rotate synchronously, which reduces the offset of the raw material, improves processing accuracy, and enhances the stability of the equipment. In the production process, the second scraper 43 can continuously clean the outer periphery of the second roller 31, efficiently removing impurities and dirt from the surface of the second roller 31, avoiding contamination of the cork paper, and reducing embossing defects. When the first roller 22 moves to the top, the first scraper 41 can also clean the first roller 22, reducing the frequency of downtime for cleaning.
