[0026] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0027] like Figures 1 to 5 As shown, a three-roller cleaning device in one embodiment of the present invention includes a body 1, on which a roller 2 is mounted. The body 1 drives the roller 2 to rotate, and during the rotation of the roller 2, the roller 2 can grind and disperse the material. The body 1 is equipped with a discharge plate 3 that matches the roller 2 and can discharge the material processed by the roller 2. A control panel 4 is also mounted on one side of the body 1. The control panel 4 can be used to operate the body 1, including changing the speed and direction of the roller 2 and other parameters. The status of the body 1 and roller 2, including parameters such as speed and temperature, can also be displayed.

[0028] like Figures 1 to 5As shown, two slide rails 5 are installed on the upper end of the machine body 1. The two slide rails 5 are respectively located on both sides of the roller 2, that is, the roller 2 is located between the two slide rails 5. A concave frame 6 is slidably connected to the slide rail 5, and a scraper 8 is installed on the concave frame 6. The scraper 8 can scrape the roller 2 to remove the material on the roller 2, thereby cleaning the three-roller machine.

[0029] Specifically, such as Figures 1 to 5 As shown, the slide rail 5 is provided with a chute 501. A slide seat 601, which matches the chute 501, is fixedly connected to the lower end of the concave frame 6. The slide seat 601 slides within the chute 501. In other words, the concave frame 6 is slidably connected to the slide rail 5 through the chute 501 and the slide seat 601. As the concave frame 6 slides on the slide rail 5, the position of the scraper 8 can be changed, allowing the scraper 8 to contact different rollers 2, thereby scraping material from different rollers 2.

[0030] After scraping, the scraper 8 will accumulate materials on the scraper 8. If there are too many materials, when using the scraper 8 to clean the roller 2, the scraper 8 needs to be cleaned again, which is troublesome. Figures 1 to 5 As shown, the scraper 8 is provided with a through-hole 802, and a storage bin 9 is mounted on the scraper 8 to match the through-hole 802. The storage bin 9 has a storage function, and the material scraped by the scraper 8 is stored in the storage bin 9. The storage bin 9 is generally made of rubber and is larger at the top and smaller at the bottom. One end of the storage bin 9 can easily pass through the through-hole 802, and the other end is interlocked with the outer wall of the through-hole 802. With greater force, the through-hole 802 and the storage bin 9 can be separated.

[0031] Storage bin 9 is removable and functions as a material storage device. Material scraped by scraper 8 is temporarily stored in storage bin 9, preventing the surface of scraper 8 from becoming clogged with material. This minimizes the impact of excessive accumulation of material on scraper 8, which could affect scraper 8's cleaning efficiency. The same material can be stored in the same storage bin 9. Once a certain amount of material has been stored, the bin 9 can be removed and a new one installed in through-hole 802. The filled storage bin 9 can be cleaned and recycled, contributing to energy conservation and environmental protection.

[0032] like Figures 1 to 5As shown, the concave frame 6 is fixedly connected to the mounting frame 7, and the scraper 8 is fixedly connected to the connecting rod 801 that matches the mounting frame 7. The mounting frame 7 has a waist hole 701, and the connecting rod 801 has a threaded hole 8011 that matches the waist hole 701. A bolt 10 is mounted on the mounting frame 7, which slides in the waist hole 701 and then passes through the waist hole 701 to be threadedly connected to the connecting rod 801. In other words, the mounting frame 7 and the scraper 8 are connected in a sliding manner. By sliding the scraper 8 on the mounting frame 7, the distance between the scraper 8 and the roller 2 can be adjusted, facilitating the cleaning of rollers 2 of different specifications. Furthermore, by changing the position of the scraper 8 on the mounting frame 7, the friction between the scraper 8 and the roller 2 can be increased or decreased. The friction coefficient between the scraper 8 and the roller 2 can be adjusted according to the actual material to achieve different cleaning effects.

[0033] Since the mounting frame 7 and the scraper 8 are fixed by bolts 10, the mounting frame 7 and the scraper 8 are detachable, making it easy to replace the scraper 8. If the scraper 8 is needed to clean the discharge plate 3, the scraper 8 can be removed and the two connecting rods 801 can be used as handles to clean the material on the discharge plate 3.

[0034] like Figures 1 to 5 As shown, a handle 602 is also installed on the concave frame 6, and the handle 602 is used to push the concave frame 6, thereby facilitating the change of the position of the scraper 8.

[0035] As the name implies, the three-roller machine has three rollers 2. In order to further improve the efficiency of the scraper 8 in cleaning the three-roller machine, it is convenient to position the scraper 8. Figures 1 to 5 As shown, the sidewall of the chute 501 is provided with a positioning groove 5011 that matches the roller 2. The sidewall of the slide 601 is provided with a blind hole 6011 that matches the positioning groove 5011. A protrusion 12 is slidably connected within the blind hole 6011, and a spring 11 is installed between the protrusion 12 and the bottom wall of the spring 11. When the blind hole 6011 can enter the positioning groove 5011, the resistance to pushing the concave frame 6 increases, indicating that the concave frame 6 has been pushed into place. The scraper 8 is then adjusted to contact the roller 2 to complete the cleaning of the roller 2. Increasing the pushing force causes the protrusion 12 to disengage from the positioning groove 5011 until the protrusion 12 enters the next positioning groove 5011, allowing the cleaning of the second roller 2 to be completed.

[0036] Generally, the length of the scraper 8 is the same as that of the roller 2. In the prior art, there are also three-roller mills with baffles on both sides of the roller 2 to adjust the working length of the roller 2. To adapt the scraper 8 to rollers of different lengths, the scraper 8 can be spliced ​​or slidably connected, allowing the length of the scraper 8 to be changed, thereby improving the applicability of the scraper 8.

[0037] When using, such as Figures 1 to 5As shown, first, push the scraper 8 to one end of the machine body 1. At this point, the presence of the concave frame 6, mounting bracket 7, and scraper 8 does not affect the normal operation of the three-roller machine. To clean the first roller 2, push the concave frame 6 with handle 602 until the protrusion 12 is located in the first positioning groove 5011, completing the pushing of the concave frame 6. Then, by loosening the bolts 10, the position of the scraper 8 can be adjusted up and down, causing it to contact the surface of the roller 2. The bolts 10 are then tightened to secure the mounting bracket 7 and scraper 8. The three-roller machine is then started, causing the roller 2 to rotate. During rotation, the roller 2 creates friction with the scraper 8, causing material on the roller 2 to fall into the scraper 8 and, following the direction of the scraper 8, enter the storage bin 9 for temporary storage. After cleaning the first roller 2, pull the scraper 8 upward, ensuring that its lower surface is higher than the first roller 2. This minimizes the possibility that the lower end of the scraper 8 is too low, which could affect the sliding of the concave frame 6 on the slide rail 5.

[0038] After the concave frame 6 and the second roller 2 are in place, loosen the bolt 10 and move the scraper 8 downward so that the scraper 8 contacts the second roller 2 to clean the roller 2. The same is true for the cleaning steps of the third roller 2.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
