Description

Technical Field

[0001] This utility model relates to the field of color masterbatch granulation machine technology, and in particular to a color masterbatch granulation machine for pigment production. Background Technology

[0002] A color masterbatch granulator is a key piece of equipment specifically designed for the production of color masterbatches. It mixes raw materials such as pigments, dispersants, and carrier resins in a certain proportion, and uses the rotation and shearing action of the screw to melt, mix, and plasticize them under high temperature and high pressure. This ensures that the pigments are evenly dispersed in the carrier resin, forming a stable dispersion system. Subsequently, the material is extruded into the die head, formed into strips or lines through a specific mold, and then cut into granular color masterbatches after cooling.

[0003] Color masterbatch granulators use specific mechanical and thermal actions to mix and plasticize raw materials such as pigments, dispersants, and carrier resins into a uniform melt, which is then extruded and cut into granular color masterbatch. However, existing color masterbatch granulators do not have the function of mixing raw materials before processing, resulting in poor product quality. Therefore, this utility model proposes a color masterbatch granulator for pigment production to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a masterbatch granulator for pigment production, which solves the problem that the existing technology lacks the function of mixing raw materials before processing, resulting in poor product quality.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a masterbatch granulator for pigment production, comprising a workbench, a masterbatch granulator body and a mixing tank, wherein the masterbatch granulator body is fixedly installed on the top of the workbench, the mixing tank is connected to the top of one end of the masterbatch granulator body, a feed pipe is connected to one side of the top of the mixing tank, a feed hopper is connected to the top of one end of the feed pipe, and an abrasive mechanism is provided inside the mixing tank.

[0006] A further improvement is that the abrasive mechanism includes a rotating shaft, a connecting frame, abrasive rollers, and a connecting shaft. The top of the mixing tank is rotatably connected to the rotating shaft, the outer side of the rotating shaft is fixedly connected to the connecting frame, and multiple abrasive rollers are rotatably connected to the outer side of the rotating shaft through the connecting shaft.

[0007] A further improvement is made in that: an abrasive chamber is provided inside the mixing tank, the abrasive roller is parallel to the position of the abrasive chamber, a self-locking motor B is fixedly installed on the top of the mixing tank, the output end of the self-locking motor B is fixedly connected to the top end of the rotating shaft, and a filter screen is fixedly connected inside the mixing tank.

[0008] A further improvement is that the bottom of the feed pipe, which is away from the feed hopper, is connected to a discharge pipe. The height of the discharge pipe is greater than the height of the abrasive roller, and the feed pipe is equipped with a material control mechanism.

[0009] A further improvement is that the material control mechanism includes an auger and a servo motor. The auger is rotatably connected inside the feed pipe. A servo motor is fixedly installed at one end of the feed pipe adjacent to the feed hopper. The output end of the servo motor is fixedly connected to one end of the auger.

[0010] A further improvement is that: two heaters are provided on the outer side of the color masterbatch granulator body, and multiple sets of heating wires are wound inside the heaters, with the inner side of the heating wires being attached to and connected to the outer wall of the color masterbatch granulator body.

[0011] A further improvement is that a reducer is connected to one end of the color masterbatch granulator body, and a self-locking motor A is fixedly installed on one side of the workbench, with the output end of the self-locking motor A fixedly connected to one end of the reducer.

[0012] The beneficial effects of this utility model are as follows: The self-locking motor B can drive the connecting shaft to rotate inside the mixing tank through the rotating shaft. The connecting shaft drives the abrasive roller to rotate inside the abrasive bin around the center of the rotating shaft. The abrasive roller and the abrasive bin rub against both sides of the color masterbatch raw material to grind the color masterbatch raw material. The friction between the abrasive roller and the color masterbatch raw material will cause the roller to rotate. The centrifugal force will drive the pulverized color masterbatch raw material to rotate and mix evenly in the abrasive bin. Color masterbatch raw material of suitable size passes through the sieve holes of the filter screen and enters the interior of the color masterbatch granulator body through the bottom of the mixing tank for granulation. Unqualified color masterbatch raw material is retained at the top of the filter screen and continues to be ground. Attached Figure Description

[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0018] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a masterbatch granulator for pigment production, including a workbench 1, a masterbatch granulator body 2, and a mixing tank 5. The masterbatch granulator body 2 is fixedly installed on the top of the workbench 1. The top of one end of the masterbatch granulator body 2 is connected to the mixing tank 5. One side of the top of the mixing tank 5 is connected to a feed pipe 7. The top of one end of the feed pipe 7 is connected to a feed hopper 6. The mixing tank 5 is equipped with an abrasive mechanism. The masterbatch raw material is fed into the feed pipe 7 through the feed hopper 6 and then transported to the mixing tank 5 through the feed pipe 7. The abrasive mechanism crushes the masterbatch raw material to ensure uniform pigment distribution. Subsequently, the mixture enters the extrusion system, where it is melted, mixed, and plasticized under the rotation and shearing action of the screw. The special design of the screw ensures that the pigment is uniformly dispersed in the carrier resin. The molten material is extruded to the die head and formed into strips or lines through the die. It is then cooled and solidified by a cooling water tank. Finally, the cooled material is cut into granular masterbatch by a pelletizer.

[0019] The bottom of the feed pipe 7, away from the feed hopper 6, is connected to a discharge pipe. The height of the discharge pipe is greater than the height of the abrasive roller 10. The feed pipe 7 is equipped with a material control mechanism, which includes an auger 14 and a servo motor 15. The auger 14 is rotatably connected inside the feed pipe 7. The servo motor 15 is fixedly installed at the end of the feed pipe 7 adjacent to the feed hopper 6. The output end of the servo motor 15 is fixedly connected to one end of the auger 14. The servo motor 15 can drive the auger 14 to rotate inside the feed pipe 7. The auger 14 drives the color masterbatch material flowing from the feed hopper 6 into the feed pipe 7 to move towards the discharge pipe. The material is automatically transported to the mixing tank 5 through the discharge pipe. The servo motor 15 can control its own speed by the magnitude of the output current, thereby controlling the speed of the auger 14, and thus controlling the rate at which the auger 14 drives the color masterbatch material to move towards the mixing tank 5.

[0020] The abrasive mechanism includes a rotating shaft 8, a connecting frame 9, abrasive rollers 10, and a connecting shaft 11. The rotating shaft 8 is rotatably connected to the top of the mixing tank 5. The connecting frame 9 is fixedly connected to the outside of the rotating shaft 8. Multiple abrasive rollers 10 are rotatably connected to the outside of the rotating shaft 8 via the connecting shaft 11. An abrasive chamber 12 is provided inside the mixing tank 5. The positions of the abrasive rollers 10 and the abrasive chamber 12 are parallel to each other. A self-locking motor B13 is fixedly installed on the top of the mixing tank 5. The output end of the self-locking motor B13 is fixedly connected to the top of the rotating shaft 8. A filter screen 17 is fixedly connected inside the mixing tank 5. The self-locking motor B13... The rotating shaft 8 can drive the connecting shaft 11 to rotate inside the mixing tank 5. The connecting shaft 11 drives the grinding roller 10 to rotate around the center of the rotating shaft 8 inside the grinding chamber 12. The grinding roller 10 and the grinding chamber 12 rub against both sides of the color masterbatch raw material to grind the color masterbatch raw material. The grinding roller 10 will rotate on its own due to friction with the color masterbatch raw material. Using its centrifugal force, the pulverized color masterbatch raw material will rotate and be mixed evenly in the grinding chamber 12. Color masterbatch raw material of suitable size passes through the sieve holes of the filter screen 17 and enters the body 2 of the color masterbatch granulator through the bottom of the mixing tank 5 for granulation. Unqualified color masterbatch raw material is retained at the top of the filter screen 17 and continues to be ground.

[0021] Two heaters 16 are provided on the outside of the color masterbatch granulator body 2. Multiple sets of heating wires are wound inside the heaters 16. The inner side of the heating wires is attached to the outer wall of the color masterbatch granulator body 2. The heating wires inside the heaters 16 can convert electrical energy into heat energy, which is then transferred to the interior of the color masterbatch granulator body 2 to heat and shape the color masterbatch raw materials inside the color masterbatch granulator body 2.

[0022] One end of the color masterbatch granulator body 2 is connected to a reducer 3, and a self-locking motor A4 is fixedly installed on one side of the workbench 1. The output end of the self-locking motor A4 is fixedly connected to one end of the reducer 3. The output end of the self-locking motor A4 is connected to the screw inside the color masterbatch granulator body 2 through the reducer 3. The self-locking motor A4 can drive the screw inside the color masterbatch granulator body 2 to rotate.

[0023] In this masterbatch granulator, the self-locking motor B13 drives the connecting shaft 11 to rotate inside the mixing tank 5 via the rotating shaft 8. The connecting shaft 11 drives the grinding roller 10 to rotate inside the grinding chamber 12 around the center of the rotating shaft 8. The grinding roller 10 and the grinding chamber 12 rub against both sides of the masterbatch raw material to grind it. The grinding roller 10 will rotate due to friction with the masterbatch raw material, and its centrifugal force will drive the pulverized masterbatch raw material to rotate and mix evenly in the grinding chamber 12. The masterbatch raw material of suitable size passes through the sieve holes of the filter screen 17 and enters the body 2 of the masterbatch granulator 2 through the bottom of the mixing tank 5 for granulation. The unqualified masterbatch raw material is retained at the top of the filter screen 17 and continues to be ground.
