Description

Technical Field

[0001] This utility model relates to the field of color masterbatch production technology, specifically to an automated processing and production device for color masterbatch. Background Technology

[0002] Color masterbatch is a polymeric composite coloring material used for coloring materials such as plastics, synthetic fibers, and rubber. It is mainly composed of pigments, carrier resins, dispersants, and functional additives. Its core function is to uniformly disperse pigments in the resin in a high proportion, giving the product rich colors and specific functions (such as UV resistance and flame retardancy).

[0003] During the production of color masterbatch, raw materials are usually mixed in a mixing drum, then extruded into strips by a twin-screw extruder. After cooling, the strips are fed into a pelletizer for pelletizing. Since the viscosity of different components of the color masterbatch raw materials varies, and the mixing blade angle of the mixing drum is fixed, if the fixed blade angle is too large, the flow resistance of high-viscosity materials is high, and the blades need to overcome greater torque when rotating, which can easily cause blade damage. If the fixed blade angle is too small, the axial pushing force is insufficient, affecting the mixing efficiency. In addition, when cooling the strips of color masterbatch, in order to ensure sufficient cooling, the strips of color masterbatch are usually passed through a very long cooling tank, resulting in excessive space occupied by the equipment.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a second motor to drive a first threaded rod, which in turn drives a lifting plate on one side to move up and down via a bent plate. When the lifting plate on one side moves up and down, it drives a reversing gear to rotate via a second rack, which in turn drives the other lifting plate on the other side to move in the opposite direction via a second rack on the other side. The lifting plate drives the corresponding connecting gear to rotate via a first rack, which in turn drives the angle of the stirring blade to change via a rotating rod. This allows the angle of the stirring blade to be changed according to the viscosity of the raw materials in the mixing drum, effectively improving the mixing efficiency. 2. This utility model also uses a third motor to drive one side of the extension rod, which in turn drives the other side of the extension rod to rotate via a transmission belt. This causes the second threaded rods on both sides to rotate in opposite directions. Since the thread directions of the second threaded rods are opposite, the lifting blocks on both sides move in opposite directions along the lifting rods. This causes the positioning roller to move towards the strip-shaped color masterbatch via the connecting rod, thereby causing the strip-shaped color masterbatch to bend continuously and increasing the conveying distance of the strip-shaped color masterbatch in the cooling box. This allows for sufficient cooling of the strip-shaped color masterbatch while reducing the space occupied by the equipment. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5 This utility model provides a technical solution: an automated processing and production device for color masterbatch, including a mixing cylinder 1, a screw conveyor 2, a twin-screw extruder 3, and a cooling box 4. A rotating shaft 5 is rotatably installed inside the upper side of the mixing cylinder 1. Two sets of lifting plates 12 are slidably installed inside the rotating shaft 5. Three sets of intersecting first racks 13 are fixedly welded to one side of the two lifting plates 12 facing each other. A connecting gear 14 is meshed with one side of the first rack 13. A rotating rod 6 is fixedly welded to one side of the connecting gear 14. A stirring blade 7 is fixedly welded to the outside of the rotating shaft 5 through the rotating rod 6. By moving the lifting plates 12 up and down along the inside of the rotating shaft 5, the corresponding connecting gears are driven by the first racks 13. 14 rotates, thereby changing the angle of the stirring blade 7 through the rotating rod 6, and thus changing the angle of the stirring blade 7 according to the viscosity of the substance in the mixing cylinder 1. Four sets of lifting frames 31 are fixedly welded on both sides of the cooling box 4. The lifting frames 31 on both sides face each other and have a connecting groove 32. A connecting rod 35 is slidably installed inside the connecting groove 32. A positioning roller 38 is fixedly welded on the outside of the connecting rod 35. The strip-shaped color masterbatch discharged from the twin-screw extruder 3 passes between the positioning rollers 38. By moving the connecting rod 35 up and down along the connecting groove 32, the positioning roller 38 is driven to move towards the strip-shaped color masterbatch, thereby causing the strip-shaped color masterbatch to bend continuously and expand the conveying distance of the strip-shaped color masterbatch in the cooling box 4. An external gear ring 8 is fixedly welded to the upper part of the rotating shaft 5 through the outside of the mixing cylinder 1. A first mounting frame 9 is fixedly welded to the upper part of the mixing cylinder 1. A first motor 10 is mounted on the flange of the upper part of the first mounting frame 9. The power end of the first motor 10 is connected to a power gear 11 through the coupling of the first mounting frame 9. The power gear 11 meshes with the external gear ring 8. The first motor 10 drives the power gear 11, which drives the rotating shaft 5 to rotate through the external gear ring 8. This allows the stirring blades 7 to stir the raw materials inside the mixing cylinder 1, thereby improving the mixing efficiency of the raw materials. A curved plate 15 is fixedly welded to one side of the lifting plate 12 through the rotating shaft 5. A second mounting bracket 16 is fixedly welded to the upper part of the external gear ring 8. A second motor 17 is mounted on the upper flange of the second mounting bracket 16. The power end of the second motor 17 is connected to a first threaded rod 18 through the coupling of the second mounting bracket 16. The lower part of the first threaded rod 18 is rotatably connected to the external gear ring 8. The first threaded rod 18 is threaded inside the curved plate 15. The second motor 17 drives the first threaded rod 18, thereby driving the lifting plate 12 on one side to move up and down through the curved plate 15, thus moving the lifting plate 12. The movement is controlled by the lifting plates 12 on both sides facing each other and fixedly welded to one side. The second rack 20 is slidably installed on the inner side of the upper part of the rotating shaft 5. A reversing gear 19 is meshed between the two second racks 20. The reversing gear 19 is rotatably connected to the second mounting bracket 16. When one side of the lifting plate 12 moves up and down, the second rack 20 drives the reversing gear 19 to rotate, thereby driving the other side of the lifting plate 12 to move in the opposite direction through the other side of the second rack 20, thereby driving the stirring blade 7 to rotate in the opposite direction, ensuring the symmetry of the stirring blade 7. A positioning plate 21 is fixedly welded inside the upper side of the rotating shaft 5. The lifting plate 12 is slidably installed inside the positioning plate 21 to restrict the up and down movement of the lifting plate 12 and prevent the lifting plate 12 from moving in other directions. A feed pipe 22 is fixedly welded to one side of the upper part of the mixing cylinder 1. An inclined platform 23 is opened inside the lower side of the mixing cylinder 1 to facilitate the discharge of the mixture. A discharge pipe 24 is fixedly welded to the lower part of the mixing cylinder 1. One end of the screw conveyor 2 is directly opposite the lower part of the discharge pipe 24, and the other end of the screw conveyor 2 is directly opposite the upper part of the twin screw extruder 3. The strip-shaped masterbatch discharged from the twin screw extruder 3 is cooled by manually passing it through the positioning roller 38, realizing all the processes before pelletizing during the processing of masterbatch. The other end of the rotating rod 6 is rotatably connected to the mounting baffle 25. The other side of the mounting baffle 25 is internally threaded with a rubber pad 26. The rubber pad 26 is in contact with the inner wall of the mixing cylinder 1. The rotating rod 6 drives the mounting baffle 25 to restrict it. The rubber pad 26 cleans the inner wall of the mixing cylinder 1 and prevents raw materials from remaining on the inner wall of the mixing cylinder 1. Several sets of installation pipes 28 are fixedly welded to the upper side of the mixing drum 1. One set of installation pipes 28 penetrates to the upper outer side of the mixing drum 1, so that water can be introduced into the installation pipe 28 from the outside. A coil 27 is fixedly welded to the lower part of the installation pipe 28, and a water outlet pipe 29 is fixedly welded to the lower part of the coil 27. The installation pipe 28, the coil 27 and the water outlet pipe 29 are connected. The lower part of the water outlet pipe 29 is directly facing the inner wall of the mixing drum 1. Water flows through the coil 27 and is discharged from the water outlet pipe 29, spraying onto the inner wall of the mixing drum 1. After the raw materials are mixed, it can work with the rubber pad 26 to achieve a better cleaning effect. The upper part of the mixing cylinder 1 is fixedly welded with mating flanges 30, which allows the mixing cylinder 1 to be separated into upper and lower parts, and the internal parts can be replaced and repaired. The lifting frame 31 has a lifting groove 33 that communicates with the connecting groove 32. The connecting rod 35 penetrates into the lifting groove 33 and is fixedly welded to the lifting block 34. Lifting rods 36 are slidably installed inside the four sets of lifting blocks 34 on the front side. The lifting rods 36 are fixedly welded to the inside of the lifting frame 31. The two sets of lifting blocks 34 on the rear side have second threaded rods 37 threaded inside. The lower part of the second threaded rod 37 is rotatably connected to the inner wall of the lifting frame 31. The upper part of the second threaded rod 37 penetrates the lifting frame 31 and is fixedly welded to the extension rod 40. A third mounting bracket 39 is rotatably installed on the upper part of the extension rod 40 and is fixedly welded to the upper part of the lifting frame 31. A transmission belt 41 is sleeved on the outer side of two adjacent sets of extension rods 40, and the threads of two adjacent sets of second threaded rods 37 are opposite. A third motor 42 is installed on the upper flange of the third mounting bracket 39. The power end of the third motor 42 is connected to the coupling of the extension rod 40. The third motor 42 drives one side of the extension rod 40 and drives the other side of the extension rod 40 to rotate through the transmission belt 41, thereby driving the two sides of the second threaded rods 37 to rotate in opposite directions. Since the threads of the second threaded rods 37 are opposite, the two sides of the lifting blocks 34 move in opposite directions along the lifting rod 36, thereby driving the two sides of the positioning rollers 38 to bend and position the strip color masterbatch through the connecting rod 35. The second threaded rod 37 has a positioning piece 43 fixedly welded to its outer side to position the lifting block 34 at its original position, so that the strip color masterbatch can pass through the upper and lower staggered positioning rollers 38.

[0020] Working principle: In use, the mixture of color masterbatch is fed into the mixing cylinder 1 through the feed pipe 22. The first motor 10 drives the power gear 11, which drives the rotating shaft 5 to rotate through the external gear ring 8. This stirs the raw materials inside the mixing cylinder 1 through the stirring blades 7, improving the mixing efficiency of the raw materials. The second motor 17 drives the first threaded rod 18, which drives the lifting plate 12 on one side to move up and down through the bending plate 15. When the lifting plate 12 moves up and down, it drives the reversing gear 19 to rotate through the second rack 20. This drives the lifting plate 12 on the other side to move in the opposite direction through the second rack 20. The lifting plate 12 drives the corresponding connecting gear 14 to rotate through the first rack 13. This drives the angle of the stirring blades 7 to change through the rotating rod 6. The third motor 42 drives one side extension rod 40, which in turn drives the other side extension rod 40 to rotate via the transmission belt 41. This causes the second threaded rods 37 on both sides to rotate in opposite directions. Since the thread directions of the second threaded rods 37 are opposite, the lifting blocks 34 on both sides move in opposite directions along the lifting rod 36. This causes the positioning roller 38 to move towards the strip color masterbatch via the connecting rod 35, thereby causing the strip color masterbatch to bend continuously and increasing the conveying distance of the strip color masterbatch in the cooling box 4.
