Description

Technical Field

[0001] This utility model belongs to the field of color masterbatch processing technology, and specifically relates to a mixing mechanism for PC masterbatch and color masterbatch. Background Technology

[0002] PC masterbatch and color masterbatch are the core raw materials for producing colored PC (polycarbonate) plastic products. They complement each other. PC masterbatch is mainly composed of high-purity PC resin, containing a small amount of antioxidants, lubricants and other additives. It is the matrix skeleton of the product and determines its core properties—such as high strength, impact resistance, heat resistance and light transmittance. At the same time, it is suitable for processing technologies such as injection molding and extrusion. Color masterbatch is a composite particle of high-concentration pigments, carrier resin and dispersing agents. Its core function is to accurately impart color: pigments provide color, carrier resins need to be compatible with PC to ensure dispersion, and additives prevent pigment agglomeration. The two need to be mixed evenly in proportion by mixing equipment in order to produce PC products with qualified performance and uniform color. High-speed mixers are one type of equipment used for mixing PC masterbatch and color masterbatch. However, residues may adhere to the inner wall of the equipment during use. Since the stirring rods inside the equipment take up too much space when not disassembled, it is difficult to clean the inner wall of the equipment. If it is not cleaned or not cleaned thoroughly, it may affect the material ratio during the next mixing, or cause contamination when processing a different material. Utility Model Content

[0003] The purpose of this invention is to provide a mixing mechanism for PC masterbatch and color masterbatch, which has the advantage of cleaning the inner wall of the equipment and improving cleaning efficiency.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a mixing mechanism for PC masterbatch and color masterbatch, including a central rod, several sets of stirring rods welded to the surface of the central rod, a connecting pipe welded to the upper end of the surface of the central rod, a fixing ring welded to both ends of the surface of the connecting pipe, four sets of spring push rods bolted to one side of the fixing ring, and a slant plate bolted to the piston end of two sets of spring push rods.

[0005] The above technical solution involves: A ring is fitted onto the outer surface of the connecting pipe. When the ring is fitted and the mounting plate is positioned between the two sets of inclined plates, the sliding shell inside the sliding hole causes the mounting plate to press against the inclined surfaces of the two sets of inclined plates. Since the inclined surfaces of the inclined plates are made of tempered glass and are relatively smooth, when the inclined plates are pressed by the mounting plate, they will move to one side using a spring-loaded rod. When the mounting plate continues to move and passes over the pressing action on the inclined plates, the spring-loaded rod will cause the inclined plates to move and reset, so that the upper and lower sets of inclined plates are simultaneously clamped and limited on the surface of the mounting plate, thus completing the fixing of the mounting plate.

[0006] The present invention is further provided that baffles are welded to both sides of the inner wall of the inclined plate, and the baffles are rectangular in shape.

[0007] The above technical solution is adopted: the baffles on the inner wall of the inclined plate located on both sides of the mounting plate will limit the mounting plate to both sides, which can prevent the mounting plate from rotating inside the two sets of inclined plates.

[0008] The present invention is further configured such that an installation plate is detachably connected inside the inclined plate, and a sliding shell is welded to one side of the installation plate.

[0009] Using the above technical solution: when the inclined plate is squeezed by the mounting plate, the inclined plate will move to one side using the spring push rod.

[0010] The present invention is further configured such that the two sets of sliding shell surfaces are slidably connected by a connecting ring, and holes are provided on both sides of the connecting ring, and the holes are slidably connected to the sliding shell.

[0011] Using the above technical solution: the fixing plate will be in a sliding connection with the inside of the sliding shell.

[0012] The present invention is further configured such that a fixing plate is slidably connected inside the sliding shell, a scraper is welded to one end of the fixing plate, and a screw is threadedly connected inside the sliding shell, and the screw and the fixing plate are detachably connected.

[0013] Using the above technical solution: when installing the scraper inside the equipment, first tighten the screws so that the screws stop pressing against the fixing plate and do not fall out of the sliding housing (to prevent the screws from being lost), the fixing plate will be in a sliding connection with the inside of the sliding housing.

[0014] The present invention is further configured such that two sets of connecting rods are welded to both sides of the connecting pipe surface, a connecting plate is welded to one end of each set of connecting rods, and two sets of cleaning plates are welded to one side of the connecting plate.

[0015] Using the above technical solution: During the long-term scraping process of materials adhering to the inner wall of the equipment, some waste materials that are not easy to clean will also stick to the surface of the scraper. Therefore, in order not to affect the normal operation of the equipment, the inclined plates can be pushed to both sides, so that the inclined plates limited on the surface of the mounting plate can be moved to one end. This allows the mounting plate to be removed from the inside of the inclined plates. Then, the linkage can be lifted, causing the linkage to move the sliding shell, screws, fixing plate, and scraper upward. During the upward movement, the scraper will be located between the two sets of connecting plates, and the scraper will be scraped by the cleaning plate on the inner wall of the connecting plate. In this way, the cleaning plate will remove the impurities on the surface of the scraper. The connecting rod connects the connecting plate and the connecting pipe, so the cleaning plate will move with the movement of the scraper, so that the cleaning plate can always be kept directly above the scraper for easy cleaning of the scraper.

[0016] In summary, this utility model has the following beneficial effects: 1. The design of the inclined plate and mounting plate enables quick installation of the scraper, saving unnecessary time spent on scraper installation and removal, and increasing practicality; 2. The scraper design allows for convenient and quick removal of impurities adhering to the inner wall of the equipment, preventing material contamination during the next mixing process due to incomplete cleaning. 3. The cleaning plate design effectively and quickly removes impurities stuck to the scraper surface, achieving a time-saving and labor-saving effect. Attached Figure Description

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Example 1: refer to Figures 1-3 and Figure 5 A mixing mechanism for PC masterbatch and color masterbatch includes a central rod 1, several sets of stirring rods 2 are welded to the surface of the central rod 1, a connecting pipe 14 is welded to the upper end of the surface of the central rod 1, and a fixing ring 13 is welded to both ends of the surface of the connecting pipe 14. Four sets of spring push rods 12 are bolted to one side of the fixing ring 13, and a slant plate 16 is bolted to the piston end of two sets of spring push rods 12.

[0021] Both sides of the inner wall of the inclined plate 16 are welded with baffles 17, and the baffles 17 are rectangular.

[0022] An installation plate 11 is detachably connected inside the inclined plate 16, and a sliding shell 9 is welded to one side of the installation plate 11.

[0023] The surfaces of the two sets of sliding shells 9 are slidably connected by a connecting ring 10. Holes 15 are provided on both sides of the connecting ring 10, and the holes 15 are slidably connected to the sliding shells 9.

[0024] The sliding housing 9 has a fixed plate 7 slidably connected inside. A scraper 6 is welded to one end of the fixed plate 7. The sliding housing 9 has a screw 8 threaded inside, and the screw 8 and the fixed plate 7 are detachably connected.

[0025] Brief description of the usage process: When installing the scraper 6 inside the equipment, first tighten the screw 8 until it stops pressing against the fixing plate 7 and does not fall out of the sliding shell 9 (to prevent the screw 8 from being lost). The fixing plate 7 will then be in a sliding connection with the inside of the sliding shell 9. Then, the connecting ring 10 is fitted onto the outer surface of the connecting pipe 14. When the connecting ring 10 is fitted and the mounting plate 11 is positioned between the two sets of inclined plates 16, the sliding shell 9 inside the sliding hole 15 is slidable. This causes the sliding shell 9 to drive the mounting plate 11 to press against the inclined surfaces of the two sets of inclined plates 16. Since the inclined surfaces of the inclined plates 16 are made of tempered glass and have a relatively smooth surface, when the inclined plates 16 are pressed by the mounting plate 11, the inclined plates 16 will move to one side using the spring push rod 12. As the mounting plate 11 continues to move and passes over the pressing force on the inclined plates 16... When pressed, the spring rod 12 will drive the inclined plate 16 to move and reset, so that the upper and lower inclined plates 16 are simultaneously clamped and limited on the surface of the mounting plate 11, thus completing the fixation of the mounting plate 11. The baffles 17 on both sides of the mounting plate 11 on the inner wall of the inclined plate 16 will limit the mounting plate 11 to both sides, thus preventing the mounting plate 11 from rotating inside the two sets of inclined plates 16. Then, the fixed plate 7 inside the sliding shell 9 is slid, so that the scraper 6 at one end of the fixed plate 7 is attached to the inner wall of the equipment. After completion, the screw 8 is turned so that the screw 8 passes through the sliding shell 9 and is tightly pressed against the surface of the fixed plate 7, thus completing the fixation of the position of the fixed plate 7 and the scraper 6. The scraper 6 is designed to rotate with the rotation of the central rod 1 and the stirring rod 2 (used for mixing PC masterbatch and color masterbatch powder), thereby scraping off the material adhering to the inner wall of the equipment.

[0026] Example 2: refer to Figure 4 Two sets of connecting rods 3 are welded to both sides of the surface of the connecting pipe 14. A connecting plate 4 is welded to one end of each set of connecting rods 3. Two sets of cleaning plates 5 are welded to one side of the connecting plate 4.

[0027] Brief description of the usage process: During the long-term scraping of materials adhering to the inner wall of the equipment, scraper 6 will also have some waste materials that are not easy to clean off on its surface. Therefore, in order not to affect the normal operation of the equipment, the inclined plate 16 can be pushed to both sides, so that the inclined plate 16, which is limited on the surface of the mounting plate 11, can be moved to one end. This allows the mounting plate 11 to be removed from the inside of the inclined plate 16. Then, the connecting ring 10 can be lifted, causing the connecting ring 10 to drive the sliding shell 9, screw 8, fixing plate 7, and scraper 6 to move upward. During the upward movement, scraper 6 will be located between the two sets of connecting plates 4, and scraper 6 will be scraped by the cleaning plate 5 on the inner wall of the connecting plate 4. In this way, the cleaning plate 5 will remove the impurities on the surface of scraper 6. The connecting rod 3 connects the connecting plate 4 and the connecting pipe 14, so the cleaning plate 5 will move with the scraper 6, so that the cleaning plate 5 can always be kept directly above the scraper 6 for easy cleaning.

[0028] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
