Description

Technical Field

[0001] This utility model belongs to the field of color masterbatch drying technology, and in particular relates to a color masterbatch drying device for injection molding. Background Technology

[0002] Masterbatch, also known as colorant or colorant granules, is a new type of colorant specifically designed for polymer materials, also called pigment preparation. It is primarily used in plastics. Masterbatch consists of three basic elements: pigment or dye, carrier, and additives. It is an aggregate obtained by uniformly loading an excessive amount of pigment into resin, and can be called a pigment concentrate, thus its coloring power is higher than that of the pigment itself. During processing, a small amount of masterbatch is mixed with uncolored resin to achieve the designed pigment concentration in the resin or product. After the masterbatch is formed, it needs to be dried using drying equipment. Authorization announcement number CN211307038U discloses a stirring and drying device for producing new material masterbatch, including a cavity, a stirring shaft installed inside the cavity, a stirring paddle outside the stirring shaft, a scraper below the stirring paddle and connected to the stirring shaft via a connecting rod, an air duct outside the stirring paddle and connected to the inner wall of the cavity via a fixing rod, an intercepting net inside the air duct, a discharge port at the bottom of the cavity, a support leg outside the discharge port and fixedly connected to the cavity, a stirring motor installed at the top of the cavity and its output shaft fixedly connected to the stirring shaft, a feed inlet on one side of the stirring motor, and a processing box on the side of the cavity. The device has a simple structure and reasonable design, capable of stirring and drying masterbatch, and can discharge all dried masterbatch, avoiding the hassle of manual cleaning. However, when all the masterbatch is piled up inside the cavity for stirring and drying, the overlapping of the masterbatch particles can easily cause some particles to be insufficiently dried, thus affecting the drying effect. Utility Model Content

[0003] Based on the above background, the purpose of this utility model is to provide a drying device for color masterbatch used in injection molding.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A drying device for color masterbatch for injection molding includes a first drying chamber and a second drying chamber, wherein the first drying chamber is located on top of the second drying chamber and the first drying chamber is connected to the second drying chamber; The first drying box is rectangular, and the second drying box is horizontal cylindrical; The first drying chamber is provided with a feed inlet at the top, and the first drying chamber is provided with a guide plate, an air supply plate and an electric heating plate from top to bottom; The air supply plate is connected to the hot air box, and the hot air box is located outside the first drying box; The second drying oven is equipped with a rotating shaft, and the side of the rotating shaft is provided with stirring blades, the side of the stirring blades being in contact with the inner wall of the second drying oven; The bottom of the second drying chamber is equipped with a discharge port; The side of the second drying oven is connected to the hot air box via a ventilation pipe.

[0005] Furthermore, a drive motor is provided on the side of the second drying oven, and the drive motor is connected to the rotating shaft.

[0006] Furthermore, the guide plate, air supply plate, and heating plate are all inclined, and the inclination direction of the guide plate and the heating plate is downward from right to left; The air supply plate is tilted downwards from left to right.

[0007] Furthermore, the first drying chamber is provided with a sliding groove inside, the guide plate is slidably disposed in the sliding groove, and the left end of the guide plate is rotatably connected to the sliding groove. The first drying chamber is provided with a vibration motor outside, and one end of the guide plate is connected to the vibration motor through a connecting plate. The connecting plate is slidably connected to the first drying chamber.

[0008] Furthermore, the guide plate is provided with arc-shaped protrusions, which are arranged in a linear array uniformly along the inclined direction of the guide plate.

[0009] Furthermore, the air supply plate is provided with multiple air outlet holes, the diameter of which is smaller than the particle size of the color masterbatch.

[0010] Furthermore, the air outlet is angled upwards from left to right.

[0011] Furthermore, the heating plate is equipped with heating wires inside.

[0012] Furthermore, both the first and second drying boxes are equipped with exhaust pipes.

[0013] This utility model has the following beneficial effects: 1. The material falls from the feed inlet onto the guide plate and rolls along the inclined direction of the guide plate onto the air supply plate.

[0021] like Figure 1-4As shown, a drying device for injection molding masterbatch includes a first drying chamber 1 and a second drying chamber 2. The first drying chamber 1 is located on top of the second drying chamber 2, and the bottom of the first drying chamber 1 is connected to the top of the second drying chamber 2. The first drying chamber 1 is rectangular, and the second drying chamber 2 is a horizontal cylinder. The top of the first drying chamber 1 is provided with a feed inlet 11, which is located at the right end of the top of the first drying chamber 1. Inside the first drying chamber 1, from top to bottom, there are a guide plate 3, an air supply plate 4, and a heating plate 5. The guide plate 3, the air supply plate 4, and the heating plate 5 are all inclined. The inclination direction of the guide plate 3 and the heating plate 5 is downward from right to left. The inclination direction of the air supply plate 4 is downward. The material guide plate 3 is inclined downwards from left to right. It has arc-shaped protrusions 33 arranged in a linear array along the inclined direction of the guide plate 3. The air supply plate 4 is connected to the hot air box 6, which is located outside the first drying chamber 1. The side of the second drying chamber 2 is connected to the hot air box 6 via a ventilation pipe 61. The hot air box 6 contains an air pump and an air heater, which delivers hot air to the first drying chamber 1 and the second drying chamber 2. The material falls from the feed inlet 11 onto the guide plate 3, rolls down the inclined direction of the guide plate 3 onto the air supply plate 4, and the air supply plate 4 blows out hot air to perform preliminary drying on the material. Then, the material rolls down onto the heating plate 5 and passes through the heating plate 5. The material undergoes a second drying process. Pre-drying is completed in the first drying chamber 1, which removes most of the moisture. The material then rolls off the heating plate 5 and enters the second drying chamber 2 from the bottom of the first drying chamber 1. A rotating shaft 21 is installed inside the second drying chamber 2, with both ends rotatably connected to the front and rear inner walls of the second drying chamber 2. Stirring blades 22 are located on the side of the rotating shaft 21, and their sides are in contact with the inner wall of the second drying chamber 2. A drive motor 24 is located on the side of the second drying chamber 2, and one end of the drive motor 24 is connected to the rotating shaft 21. A discharge port 23 is located at the bottom of the second drying chamber 2, and a valve is installed on the discharge port 23, which can be a manual valve or a manual valve. An electric valve is used to open the discharge port 23 for material discharge. After the material enters the second drying chamber 2, the drive motor 24 drives the rotating shaft 21 to rotate, which in turn drives the stirring blades 22 to rotate. There are multiple stirring blades 22, which divide the second drying chamber 2 into multiple partitions. The number of through holes connecting the ventilation pipe 61 to the second drying chamber 2 can correspond to the number of partitions, so that each partition has airflow. The partitions can move due to the rotation of the stirring blades 22, and the material falls evenly into the partitions. The hot air sent in by the ventilation pipe 61 on the front side further dries the material. When the material moves in a circular motion with the partitions, it can move fully, avoiding material accumulation and better ensuring the drying effect.

[0022] The first drying chamber 1 has a sliding groove 12 inside, and a guide plate 3 is slidably disposed in the sliding groove 12. The left end of the guide plate 3 is rotatably connected to the sliding groove 12. A vibration motor 31 is provided outside the first drying chamber 1. One end of the guide plate 3 is connected to the vibration motor 31 through a connecting plate 32. The connecting plate 32 is slidably connected to the first drying chamber 1. The guide plate 3 vibrates with the vibration motor 31, and the material falling on the guide plate 3 vibrates accordingly, preventing the material from sticking together due to high moisture content. The air supply plate 4 has multiple air outlets 41, and the diameter of the air outlets 41 is... The colorimetric masterbatch has a small particle size. The air outlet 41 is inclined upward from left to right. The air outlet 41 is connected to the inside of the air supply plate 4. The air outlet direction is opposite to the material rolling direction, so that the material moves in the opposite direction to the hot air flow. This allows the hot air flow to carry away the moisture in the material more quickly. The electric heating plate 5 is equipped with electric heating wires. The electric heating wires heat the electric heating plate 5 and further dry the material rolling on it. Both the first drying box 1 and the second drying box 2 are equipped with exhaust pipes 7. The exhaust pipes 7 discharge the water vapor in the first drying box 1 and the second drying box 2.

[0023] The working principle of this utility model is as follows: Material is fed into the first drying chamber 1 through the feed inlet 11. The vibration motor 31 drives the guide plate 3 to vibrate, causing the material falling onto the guide plate 3 to vibrate accordingly. This prevents the material from sticking together due to high moisture content. The material then falls from the left end of the guide plate 3 onto the air supply plate 4. Hot air enters the air supply plate 4 from the hot air box 6 and enters the first drying chamber 1 through the air outlet 41. The air outlet direction is opposite to the material's rolling direction, causing the material to move in the opposite direction to the hot air flow. This allows the hot air flow to more quickly remove moisture from the material. The material then falls from the right end of the air supply plate 4 onto the electric heating plate 5, where it is electrically... The hot plate 5 dries the material a second time and it enters the second drying chamber 2 from the bottom of the first drying chamber 1. The drive motor 24 drives the rotating shaft 21 to rotate, which in turn drives the stirring blade 22 to rotate. The stirring blade 22 divides the second drying chamber 2 into multiple compartments, and the compartments can move due to the rotation of the stirring blade 22. The material falls evenly into the compartments and is further dried by the hot air sent in through the ventilation pipe 61 on the front side. The material can move freely as it moves in a circular motion with the compartments, which avoids material accumulation and better ensures the drying effect. The moisture is discharged from the exhaust pipe 7. After drying, the material is discharged from the discharge port 23.

[0024] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
