By providing the adjusting device 3, the effect of removing the material adhered to the arc surface of the roller 2 is achieved, avoiding that when the roller 2 processes the material, since the material is rolled between the two rollers 2, some material will adhere to the arc surface of the roller 2 during the rolling process, resulting in the need for the staff to stop processing multiple times to clean the roller 2, and continuous processing will cause the density and flatness of the material to decrease. The practicability of the device is improved. Protection devices 4 are arranged on both sides of the operation bin 1. By providing the protection devices 4, the effect of shielding the roller 2 during the process of rolling the material is achieved, preventing the excessive material accumulated between the two rollers 2 from moving to both sides and getting out of the operation bin 1, thus improving the stability of the device.

[0029] Next, the specific settings and functions of its adjusting device 3 and protection device 4 will be specifically described.

[0030] Referring to Figure 2 andFigure 3 As shown in the figure, in this embodiment: The adjusting device 3 includes two long rods 301. The two long rods 301 are respectively rotatably connected to the inner surface of the sliding holes of the operation chamber 1. A connecting plate 302 is fixedly connected to the arc surface of the long rod 301. A sliding groove is formed on the surface of the connecting plate 302. A scraping plate 303 is slidably connected to the inner surface of the sliding groove of the connecting plate 302. One end of the long rod 301 is fixedly connected with an elliptical plate 305. A screw rod 304 is inserted into the elliptical plate 305 in a threaded manner. One end of the screw rod 304 abuts against the operation chamber 1. Both sides of the scraping plate 303 are fixedly connected with short rods 306. A connecting block 307 is slidably connected to the arc surface of the short rod 306. One side of the connecting block 307 is fixedly connected with a limiting rod 308. Limiting grooves are formed on both sides of the connecting plate 302. A spring 309 is sleeved on the arc surface of the short rod 306. Both ends of the spring 309 are fixedly connected with the sliding plate and the connecting block 307 respectively. Pull the connecting block 307 to drive the limiting rod 308 to move until it disengages from the limiting groove in the connecting plate 302, so as to facilitate the staff to replace the scraping plate 303, prevent the surface of the scraping plate 303 from being worn after long-term use, and avoid the situation of the scraping effect decreasing. A blocking block 310 is fixedly connected to the end of the short rod 306 away from the scraping plate 303. The size of the limiting rod 308 is adapted to the size of the limiting groove of the connecting plate 302. Pull the connecting block 307 to drive the limiting rod 308 to move until the connecting block 307 contacts the blocking block 310, avoiding the situation that the connecting block 307 disengages from the short rod 306 during the process of the staff replacing the sliding plate and pulling the connecting block 307. Two torsion springs 312 are sleeved on the arc surface of the long rod 301. Both ends of the torsion spring 312 are fixedly connected with the inner surface of the operation chamber 1 and the connecting plate 302 respectively. Rotate the screw rod 304 to rotate in the elliptical plate 305 until the screw rod 304 does not contact the surface of the operation chamber 1. The torsion of the torsion spring 312 drives the connecting plate 302 to rotate automatically and open on the arc surface of the long rod 301, and maintains the position state of the connecting plate 302. A gasket 311 is fixedly connected to one end of the screw rod 304. Rotate the screw rod 304 to rotate in the elliptical plate 305, and the screw rod 304 drives the gasket 311 to move, so as to increase the contact area between the screw rod 304 and the operation chamber 1 and improve the stability of the device.

[0031] Refer to Figure 4 As shown in the figure, specifically, the protection device 4 includes two mounting blocks 41. The two mounting blocks 41 are respectively fixedly connected to both sides of the operation chamber 1. A threaded rod 42 is inserted into the mounting block 41 in a threaded manner. One end of the threaded rod 42 is rotatably connected with a baffle 43. A handle 44 is fixedly connected to the end of the threaded rod 42 away from the baffle 43. A placing block 45 is fixedly connected to the surface of the mounting block 41. A connecting rod 46 is slidably inserted into the placing block 45. One end of the connecting rod 46 is fixedly connected with the baffle 43. Rotate the handle 44 to drive the threaded rod 42 to rotate in the mounting block 41. The threaded rod 42 drives the baffle 43 to move. The baffle 43 drives the connecting rod 46 to slide in the placing block 45, avoiding the situation that the baffle 43 rotates with the rotation of the threaded rod 42.

[0032] Working principle: When the staff rolls the material to prevent the roller 2 from sticking, rotate the long rod 301 to rotate on the inner surface of the sliding hole of the operation bin 1. The long rod 301 drives the connecting plate 302 to rotate, the connecting plate 302 drives the scraper 303 to rotate, rotate the screw rod 304 to rotate in the elliptical plate 305, and the screw rod 304 drives the gasket 311 to move until the gasket 311 abuts against the surface of the operation bin 1. When the scraper 303 needs to be replaced, pull the connecting block 307 to drive the limiting rod 308 to slide on the arc surface of the short rod 306 until the limiting rod 308 disengages from the inner surface of the limiting groove of the operation bin 1, and pull the sliding plate to disengage from the inner surface of the chute of the connecting plate 302, achieving the effect of removing the material adhered to the arc surface of the roller 2, avoiding that when the roller 2 processes the material, because the material is rolled between the two rollers 2, some material will adhere to the arc surface of the roller 2 during the rolling process, resulting in the need for the staff to stop processing multiple times to clean the roller 2, and continuous processing will cause the density and flatness of the material to decrease, improving the practicability of the device.

[0033] When the staff needs to prevent the material from falling during the process of rolling the material in the operation bin 1, rotate the handle 44 to drive the threaded rod 42 to rotate in the mounting block 41, the threaded rod 42 drives the baffle 43 to move, and the baffle 43 drives the connecting rod 46 to slide in the placing block 45, avoiding the situation that the baffle 43 rotates as the threaded rod 42 rotates, achieving the effect of shielding the material during the rolling process by the roller 2, and preventing the excessive material accumulated between the two rollers 2 from moving to both sides and falling out of the operation bin 1, improving the stability of the device.
