Abstract
Description
Technical Field
[0001] This application belongs to the field of three-roll mill technology, specifically relating to a scraping device for a three-roll mill and a three-roll mill. Background Technology
[0002] The three-roll mill, also known as a three-roll mill, is suitable for manufacturing slurries such as paints, inks, pigments, and plastics. Its working principle is to achieve the grinding effect by the mutual extrusion and friction at different speeds of the surfaces of three horizontal rollers. In production and manufacturing, the three-roll mill is the most effective grinding and dispersing equipment for high-viscosity materials.
[0003] However, due to the high viscosity of the materials ground by the three-roll mill, some residual material inevitably adheres to the discharge guide plate after the ground material is discharged from the outlet and is difficult to remove on its own. Repeated adhesion will cause blockage of the outlet, leading to production stoppage and affecting processing efficiency. Furthermore, manual supervision and cleaning is not only wasteful of manpower but also ineffective, as human resources are limited and it is difficult to clean quickly and thoroughly.
[0004] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Utility Model Content

[0010] Furthermore, the scraper component includes a scraper seat rotatably connected to the movable arm and a scraper element connected to the scraper seat, wherein the scraper element is made of an elastic material.
[0011] Furthermore, a discharge guide plate is installed at the discharge port, and the contact angle between the scraping device and the discharge guide plate when scraping the grinding material is 30 to 90°.

[0013] Furthermore, the end of the exhaust gas guide plate away from the discharge guide plate is rotatably connected to the body of the three-roll mill. The body of the three-roll mill also includes a drive component. The telescopic end of the drive component is connected to the middle of the discharge guide plate. The telescopic end can extend and retract to drive the exhaust gas guide plate to rotate relative to the machine body to open or close part of the discharge port.
[0014] Furthermore, the driving component is a cylinder.

[0025] Please see Figures 1 to 3 As shown, a three-roll mill scraping device and a three-roll mill include a three-roll mill body 1, which can grind the material to be ground and has a discharge port 11. The ground high-viscosity material can be discharged from the three-roll mill through the discharge guide plate 12 installed at the discharge port 11.
[0026] In existing technologies, due to the high viscosity of the materials ground by the three-roll mill, some residual material inevitably adheres to the discharge guide plate 12 at the discharge port 11 after the ground material is discharged through the discharge port 11. This residual material is difficult to remove on its own, and repeated adhesion will cause blockage of the discharge port 11, leading to production stoppage and affecting processing efficiency. Furthermore, manual supervision and cleaning is wasteful of manpower and the cleaning effect is not good. Human resources are limited and it is difficult to clean quickly and thoroughly.
[0027] To address the problems existing in the prior art, in this embodiment, the three-roll mill scraping device and the three-roll mill further include a scraping device 2 covering the outside of the three-roll mill body 1. The scraping device 2 includes a scraping mechanism 21, which is located above the discharge port 11. It can scrape off the abrasive material adhering to the discharge port 11, thereby ensuring the cleanliness and unobstructed flow of the discharge port 11, preventing a decrease in production efficiency due to blockage of the discharge port 11, and is faster and has a better cleaning effect than manual scraping of the adhering material.
[0028] Specifically, the scraping device 2 includes a three-dimensional frame 22 covering the three-roll mill body 1, and a scraping mechanism 21 connected to the top of the three-dimensional frame 22. The scraping mechanism 21 can move relative to the three-roll mill body 1 on the three-dimensional frame 22, thereby increasing the flexibility of the scraping mechanism 21 and covering a wider working range.
[0029] Preferably, the connection method can be selected such that one of the scraping mechanism 21 and the three-dimensional frame 22 has a slide rail, and the other of the scraping mechanism 21 and the three-dimensional frame 22 has a slide groove. The scraping mechanism 21 can move on the three-dimensional frame 22 through the sliding cooperation of the slide groove and the slide rail. The extension direction of the slide groove and the slide rail can be determined according to actual needs, and no specific limitation is made here.
[0030] The scraping mechanism 21 includes a movable arm 211 connected to the three-dimensional frame 22 and a scraper component 212 mounted on the movable arm 211. The movable arm 211 is a 6-axis robotic arm, which can drive the scraper component 212 to move and scrape in all directions to ensure the scraping effect. In other embodiments, the appropriate movable arm 211 can also be selected according to actual needs, as long as it can meet the actual needs, and no specific limitation is made here.
[0031] The scraper component 212 includes a scraper seat 2121 rotatably connected to the movable arm 211 and a scraper element 2122 connected to the scraper seat 2121. In order to prevent the scraper element 2122 from scratching the discharge guide plate 12, in this embodiment, the scraper element 2122 is made of an elastic material, such as a resin plate or a rubber plate, so as to ensure the scraping effect without scratching the discharge guide plate 12.
[0032] The contact angle between the scraping device 2 and the discharge guide plate 12 when scraping the grinding material is in the range of 30 to 90°, preferably 45°. The scraping is achieved by the edge of the scraper 2122 rubbing against the discharge guide plate 12, which ensures the cleaning effect and cleaning speed.
[0033] To eliminate the need for manual monitoring of whether material adheres to the discharge guide plate 12, this embodiment also includes a detection device 15 mounted on the three-dimensional frame 22. The detection device 15 is suitable for detecting whether there is residual grinding material on the discharge guide plate 12 after the discharge is completed. The detection device 15 is a vision detection device 15, which has high detection accuracy.
[0034] The three-roll mill body 1 is also equipped with an exhaust gas guide plate 13 connected to the mill body. This guide plate can guide and collect the exhaust gas generated during the grinding process. An exhaust gas outlet is located on the top of the mill body connected to the exhaust gas guide plate 13 and is connected to an exhaust duct. The exhaust duct can generate negative pressure at the exhaust gas outlet to draw away and collect the exhaust gas guided and collected by the guide plate, preventing pollution of the working environment. Simultaneously, the exhaust gas guide plate 13 also prevents material splashing during the grinding process. The exhaust gas guide plate 13 can be partially opened or closed by external force to the discharge port 11. In this embodiment, the end of the exhaust gas guide plate 13 away from the discharge guide plate 12 is rotatably connected to the body of the three-roll mill. The three-roll mill body 1 also includes a drive component 14. The telescopic end of the drive component 14 is connected to the middle of the discharge guide plate 12. The telescopic end can drive the exhaust gas guide plate 13 to rotate relative to the machine body to open or close part of the discharge port 11. Thus, when scraping is required, part of the discharge port 11 can be opened to prevent affecting scraping.
[0035] In this embodiment, the driving component 14 is a cylinder. In other embodiments, the corresponding driving component 14 can also be selected according to the actual situation, such as an electric cylinder, a hydraulic cylinder or a hydraulic cylinder, etc., as long as it can meet the actual needs, and no specific limitation is made here.
[0036] It is worth noting that an observation port is provided in the middle of the exhaust gas guide plate 13, and a transparent observation plate is installed at the observation port to observe the grinding progress during the grinding process.
[0037] In summary, the three-roll mill scraping device and the three-roll mill of this utility model are provided with a three-roll mill body having a suitable discharge port and a scraping device covering the outside of the three-roll mill body. The scraping device includes a scraping mechanism located above the discharge port, which can scrape off the abrasive material adhering to the discharge port, thereby ensuring the cleanliness and unobstructed flow of the discharge port, preventing the decrease in production efficiency caused by the discharge port blockage, and is faster and has a better cleaning effect than manual scraping.
[0038] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the protection scope of this utility model.
