Technical Field

[0001] The utility model relates to the technical field of preparation of modified materials special for modified plastics, in particular to a mixing device for modified materials special for modified plastics. Background Art

[0002] Modified plastics are specialized materials used in the production of modified plastics. They consist of a base resin and various additives designed to improve or impart specific properties to the plastic. The purpose of these additives is to alter the basic properties of the plastic, making it more suitable for specific applications. The preparation of these modified plastics requires mixing the resin and additives, requiring specialized mixing equipment.

[0003] Although the existing mixing device can achieve uniform mixing of resin and additives, after mixing, the inner wall of the mixing barrel and the surface of the stirring frame will be stained with modified materials. Most mixing devices can only scrape off the modified materials remaining on the inner wall of the mixing barrel, but cannot clean the modified materials on the surface of the stirring frame, which will lead to waste of modified materials and may affect the quality of the next mixing.

[0004] Therefore, a special modified material mixing device for modified plastics is particularly needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The preferred technical solution of the present utility model is described in detail below with reference to the accompanying drawings.

[0021] Example: A modified material mixing device for modified plastics, see Figures 1-4 As shown, it includes a base frame 1, a mixing barrel 2, a bottom plate 3, a bolt 301, a nut 302, a solenoid valve 4, a first motor 5, a stirring frame 6, a connecting barrel 13, a feeding barrel 14 and an observation window 17. The lower part of the mixing barrel 2 is connected to multiple base frames 1 distributed along the circumference by welding. The bottom plate 3 is fixed to the bottom of the mixing barrel 2 by multiple bolts 301. The upper end of the bolt 301 is externally threaded with a nut 302. The nut 302 contacts the mixing barrel 2 so that the bolt 301 is fixed between the mixing barrel 2 and the bottom plate 3. The nut 302 is tightly attached to the bottom surface of the mixing barrel 2. A sealing gasket is provided to prevent the nut 302 from loosening. The center position of the bottom of the mixing barrel 2 is connected by bolts. The solenoid valve 4 is connected to the first motor 5 at the top center position by means of bolts. The output shaft of the first motor 5 penetrates into the mixing barrel 2 and is connected to the stirring frame 6 by means of welding. The distance between the bottom surface of the stirring frame 6 and the top surface of the bottom plate 3 is less than or equal to 0.5 mm, ensuring that the two are almost in contact but no scratching occurs, and also ensuring that the resin and additives can be fully stirred. The left and right sides of the upper part of the mixing barrel 2 are connected to the connecting barrel 13 by means of welding, and the rear side of the connecting barrel 13 is connected to the feeding barrel 14 by means of welding. The front side of the mixing barrel 2 is embedded with an observation window 17 for viewing the situation, and also includes a scraping mechanism. The mixing barrel 2 is provided with a scraping mechanism for cleaning residual materials.

[0022] See Figure 2-Figure 4As shown, the scraping mechanism includes a scraper 7, a first magnet 8, a second motor 9, a screw 10, a movable block 11 and a second magnet 12. The scraper 7 is slidably placed inside the mixing barrel 2. The scraper 7 is provided with a cross slot for accommodating the stirring rack 6. The cross slot is consistent with the top surface pattern of the stirring rack 6 in size to ensure a smooth transition and close fit between the two. A thin silicone strip is provided on the edge of the scraper 7 in contact with the inner wall of the mixing barrel 2 and in the cross slot for accommodating the stirring rack 6 to pass through to prevent the scraper 7 from directly contacting the inner wall of the mixing barrel 2 and the surface of the stirring rack 6 to reduce wear. A first magnet 8 of the same diameter is adhered to the top of the scraper 7. The lower rear side of the mixing barrel 2 is close to the middle position. A second motor 9 is connected to the mixing barrel 2 by means of bolts, a screw 10 is connected to the output shaft of the second motor 9 through a coupling, the external thread of the screw 10 is connected to a movable block 11, a second magnet 12 is bonded to the movable block 11, the second magnet 12 is in contact with the outer wall of the mixing barrel 2, the first magnet 8 and the second magnet 12 have the same thickness and are on the same horizontal plane, ensuring that the second magnet 12 can accurately attract the first magnet 8, and the mixing barrel 2 and the bottom plate 3 are made of non-magnetic materials, such as titanium or plastic, to ensure that the mixing barrel 2 and the bottom plate 3 do not affect the attraction between the first magnet 8 and the second magnet 12, thereby ensuring the magnetic flux between the first magnet 8 and the second magnet 12.

[0023] See Figure 1-Figure 2 As shown, a third motor 15 and a spiral plate 16 are also included. The end of the connecting tube 13 away from the first motor 5 is connected to the third motor 15 by means of bolts. The output shaft of the third motor 15 penetrates into the interior of the connecting tube 13 and is connected to the spiral plate 16 by welding. The strip edge of the spiral plate 16 is close to the inner wall of the connecting tube 13 to facilitate uniform delivery of resin or additives.

[0024] When it is necessary to prepare modified materials, the staff first turns on the two third motors 15. The output shaft of the third motor 15 drives the spiral plate 16 to rotate. Then, appropriate amounts of resin and additives are poured into the two feeding barrels 14 respectively, and then flow into the connecting barrel 13 to contact the spiral plate 16. The left spiral plate 16 rotates to lower the resin into the mixing barrel 2, and the right spiral plate 16 rotates to lower the additive into the mixing barrel 2 at the same time. Then, the first motor 5 is turned on, and its output shaft drives the stirring frame 6 to rotate and stir the resin and additive so that the two begin to mix. After the pouring is completed, the third motor 15 is turned off, and after waiting for the resin and additive to be evenly mixed, the body is squatted down, and the cross groove of the scraper 7 is viewed from an upward angle through the observation window 17 to ensure that the cross groove of the scraper 7 is facing the top of the stirring frame 6. The first motor 5 is turned off, and then the charging container is placed under the mixing barrel 2, and the solenoid valve 4 is controlled to open to allow the mixing to proceed. The barrel 2 starts to discharge, and the second motor 9 is turned on so that its output shaft drives the screw 10 to rotate, and then drives the movable block 11 to drive the second magnet 12 to move downward. The second magnet 12 attracts the first magnet 8 to move downward synchronously, and the first magnet 8 drives the scraper 7 to move downward. While scraping off the residual material on the inner wall of the mixing barrel 2, the residual material on the surface of the stirring frame 6 is scraped off together, and the modified material can also be squeezed to be discharged quickly from the solenoid valve 4. When the scraper 7 moves downward to the limit, the second motor 9 is turned off, and the solenoid valve 4 stops discharging and controls the solenoid valve 4 to close. Finally, the nuts 302 are unscrewed in sequence, and the bolts 301 are released. The bolts 301 are unscrewed in sequence, and the bottom plate 3 is released. The bottom plate 3 is removed from the bottom of the mixing barrel 2 for cleaning, and the residual material on the bottom of the scraper 7 is cleaned. After cleaning, the above steps are reversed to reinstall the bottom plate 3, and the scraper 7 moves upward and reset.

The description of the above embodiments is only used to help understand the method and core idea of the present application. At the same time, for those skilled in the art, based on the idea of the present application, there may be changes in the specific implementation methods and application scope.
