Description

Technical Field

[0001] This utility model relates to the field of plastic masterbatch technology, specifically a drying device for plastic masterbatch production. Background Technology

[0002] Color masterbatch, also known as color granules or colorant, is a new type of colorant specifically for polymer materials, also called pigment preparation. Color masterbatch is mainly used in plastics. It consists of three basic elements: pigment or dye, carrier, and additives. It is an aggregate made by uniformly loading an extraordinary amount of pigment into resin, and can be called a pigment concentrate, therefore its coloring power is higher than that of the pigment itself. During processing, a small amount of color masterbatch is mixed with uncolored resin to achieve the designed pigment concentration in the resin or product.

[0003] In the preparation of color masterbatch, it needs to be dried after granulation;

[0004] Because the contact area between the hot air and the masterbatch is small, the masterbatch cannot fully exchange heat with the hot air during drying. Some masterbatches may not be effectively dried due to insufficient contact with hot air, while others may be over-dried due to localized hot air concentration. This uneven drying not only leads to poor overall drying results for the masterbatch but also seriously affects product quality. Therefore, a drying device for plastic masterbatch production is proposed. Utility Model Content

[0028] like Figures 1-5 As shown, this embodiment proposes a base plate 1 and four support legs 4 fixedly installed on the bottom surface of the base plate 1. A drying mechanism 2 and a discharge mechanism 3 are provided above the base plate 1.

[0029] The discharge mechanism 3 is located below the drying mechanism 2;

[0030] Drying mechanism 2 includes a drying section and a feeding section;

[0031] The drying section includes a connecting plate 21, a drying box 22, an air pump 25 and an air guide plate 26, and the material feeding section includes a motor 217 and a material feeding rod 211;

[0032] Connecting plate 21 is located above base plate 1. The top surface of connecting plate 21 is fixedly connected to the bottom surface of drying chamber 22. Air pump 25 is fixedly installed on the top surface of connecting plate 21. Connecting pipe 24 is fixedly installed through the top surface of air pump 25. The bottom surface of connecting pipe 24 is fixedly installed through the top surface of drying chamber 22 and extends into the interior of drying chamber 22.

Inside the drying chamber 22, a rotating rod 218 is rotatably mounted on the right end face of the inner side via a bearing seat.

An exhaust pipe 216 is fixedly installed through the right side of the drying chamber 22, extending into the interior of the drying chamber 22. A connecting rod 214 is rotatably installed on the right side of the installation plate 212 via bearing seat three. A guide vane 215 is fixedly installed on the right side of the connecting rod 214, located inside the exhaust pipe 216. A first gear 210 is fixedly sleeved on the surface of the rotating rod 218. A second gear 213 is fixedly sleeved on the surface of the connecting rod 214. The tooth surface of the first gear 210 meshes with the tooth surface of the second gear 213. The left side of the rotating rod 218 extends through the left side of the drying box 22 to the left side of the drying box 22.

A feed pipe 23 is fixedly installed through the top surface of the drying box 22 and extends into the interior of the drying box 22. A heating grid 29 is installed inside the heating box 27.

[0033] In this embodiment, the drying mechanism 2 delivers air to the heating box 27 via the air pump 25. The heated air is discharged through the air outlet 28 to dry the plastic masterbatch. The motor 217 drives the feeding rod 211 to rotate and stir the masterbatch to expand the contact area. The rotating rod 218, driven by the pulley 219, causes the air guide plate 26 to rotate and diffuse the hot air. At the same time, the first gear 210 and the second gear 213 can drive the air guide vane 215 on the connecting rod 214 to rotate, increasing the exhaust efficiency and improving the drying efficiency of the plastic masterbatch, ensuring that the masterbatch is dried evenly and with high quality. Example 2

[0034] like Figures 1-5As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that the discharge mechanism 3 includes a discharge frame 32, the left side of the discharge frame 32 extends through the right side of the drying box 22 and into the interior of the drying box 22, the front side of the discharge frame 32 is slidably provided with a baffle 38 extending into the interior of the discharge frame 32, the top surface of the bottom plate 1 is hinged with a connecting block 31, the top surface of the connecting block 31 is fixedly connected to the bottom surface of the drying box 22, the top surface of the bottom plate 1 is fixedly provided with a slide rail 36, the surface of the slide rail 36 is slidably fitted with a moving block 34, the top surface of the moving block 34 is hinged with a push plate 35, the top surface of the push plate 35 is hinged to the bottom surface of the connecting plate 21, the top surface of the bottom plate 1 is fixedly provided with an electric telescopic rod 33, the left side of the output end of the electric telescopic rod 33 is fixedly connected to the right side of the moving block 34, and the top surface of the bottom plate 1 is fixedly provided with two support rods 37, the top surfaces of the two support rods 37 are in contact with the bottom surface of the connecting plate 21.

[0035] In this embodiment, after drying, the discharge mechanism 3 can pull open the baffle 38 to discharge the masterbatch through the discharge frame 32. At the same time, the electric telescopic rod 33 controls the moving block 34 to move, and the push plate 35 lifts the left end of the connecting plate 21, causing the drying box 22 to tilt, which speeds up the discharge of plastic masterbatch and improves production efficiency.

[0036] In operation, the plastic masterbatch to be dried is first fed into the drying chamber 22 through the feed pipe 23. Then, the air pump 25 is turned on, supplying air into the heating chamber 27. The air is heated by the heating mesh 29 and then discharged through the air outlet 28, thus drying the plastic masterbatch inside the drying chamber 22. During the drying process, the motor 217 is turned on. The rotation of the motor 217 causes the material feeding rod 211 to rotate, agitating the plastic masterbatch inside the drying chamber 22 and increasing the contact between the masterbatch and the hot air. The area is increased to improve the drying efficiency. The pulley 219 drives the rotating rod 218 to rotate when the motor 217 rotates. During the rotation of the rotating rod 218, the air guide plate 26 rotates. During the rotation of the air guide plate 26, the air sprayed from the air nozzle 28 is expanded, which can further increase the contact area between the hot air and the plastic masterbatch. The water vapor generated during drying can be discharged from the exhaust pipe 216. Furthermore, the first gear 210 and the second gear 213 can cause the connecting rod 214 to rotate when the rotating rod 218 rotates. When the connecting rod 214 rotates, the air guide vane 215 rotates. When the air guide vane 215 rotates, the exhaust efficiency is increased, which can improve the drying efficiency of the plastic masterbatch.

[0037] After drying is complete, the baffle 38 is pulled forward. After the baffle 38 is separated from the discharge frame 32, the plastic masterbatch inside the drying chamber 22 will be discharged through the discharge frame 32. During the discharge process, the output end of the electric telescopic rod 33 is extended. When the output end of the electric telescopic rod 33 is extended, the moving block 34 can move to the left. When the moving block 34 moves to the left, the left end of the connecting plate 21 can be lifted by the push plate 35. After the left end of the connecting plate 21 is lifted, the drying chamber 22 can be tilted, thereby accelerating the discharge speed of the plastic masterbatch.

[0038] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
