TECHNICAL FIELD

[0001] The application belongs to the technical field of screw combination, and particularly relates to a screw combination suitable for high-content carbon black master batch. BACKGROUND

[0002] A double-screw extruder is a main forming equipment in the color master batch industry, and is divided into same direction and opposite direction according to the rotating direction. The double-screw extruder can heat plastic, apply pressure to the molten plastic, and make the molten plastic flow out of a die, so as to be cooled in a water tank and then granulated by a granulator. The extruder screw is an important component of the extruder, and is mainly used for conveying, compacting, melting, stirring and pressing the plastic.

[0003] At present, for the application field related to the product, the product needs to have good processing performance and low energy consumption ratio under the condition of ensuring high carbon black content. Specifically, the product needs to have a low filter pressure difference in the downstream processing process, so as to have a long processing time and reduce the number of stop cleaning. For the company, under the premise of obtaining good processing performance, the energy consumption ratio needs to be reduced, the equipment wear needs to be reduced, and the competitiveness in the market needs to be maintained.

[0004] Therefore, the screw combination suitable for high-content carbon black master batch is provided to solve the above problems. Content of the utility model

[0005] The screw combination suitable for high-content carbon black master batch is provided to solve the problem that the energy consumption ratio needs to be reduced and the equipment wear needs to be reduced under the premise of obtaining good processing performance in the prior art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] The transmission mechanism that this transmission mechanism is used for the transmission box is that this transmission box is fixed with the gear train of gear train and gear train is fixed with the gear train of gear train.

[0008] Preferably, the outer surface of each rotating shaft is fixedly connected to a gear, and the outer surfaces of the two gears are rotatably connected to a synchronous belt.

[0009] Preferably, a feed barrel is provided above the feed box, and the bottom surface of the feed barrel is fixedly connected to the upper surface of the feed box.

[0010] Preferably, four bolts are provided above the feed barrel, and the bottom end of each bolt passes through the feed barrel and is threadedly connected to the inner wall of the feed box.

[0011] Preferably, a support plate is fixedly connected to the back surface of the transmission box, and the upper surface of the support plate is fixedly connected to the bottom surface of the rotating motor.

[0012] Preferably, the bottom surface of the support frame is fixedly connected to a support box, and the bottom surface of the support box is fixedly connected to four bottom plates.

[0015] In summary, the technical effects and advantages of this application are:

[0016] A rotating motor is provided to drive the connecting pipe to rotate, and the connecting pipe is connected to one of the rotating shafts. When the rotating motor rotates, it can drive one of the rotating shafts to rotate. The two rotating shafts use two gears and a synchronous belt to rotate synchronously. At this time, the two rotating shafts use the first threaded piece to push the material that has just fallen forward. At this time, the inside of the limit box is in a high temperature state. The material slowly melts during the pushing process. Then it first contacts the cutter shaft, which further cuts the material that has not been completely melted, and then is pushed to the grinding shaft. At this time, the two sets of grinding shafts can be used to completely and fully grind the material back and forth to ensure that no particles are easily retained, thereby ensuring the quality of the downstream and reducing the loss of equipment. After that, the spline shaft and the push shaft are used to fully mix the material. Finally, the second threaded piece is used to continue to push the material forward for the next step of production. Such a setting can fully ensure the residence time of the product in the barrel, thereby improving the distribution and dispersion effect between the components in the high-content carbon black masterbatch, so that the product can have a better energy consumption ratio while maintaining good filtration performance and reduce wear on the equipment.

[0026] The output end of the power of the rotating motor 5 passes through the transmission box 2 and is fixedly connected to the connecting pipe 6. The inner wall of the limit box 4 is rotatably connected to two rotating shafts 7. The outer surface of each rotating shaft 7 is fixedly connected to a gear 8. The outer surfaces of the two gears 8 are jointly rotatably connected to a synchronous belt 9. The cooperation of the two gears 8 and the synchronous belt 9 allows the two rotating shafts 7 to achieve the effect of simultaneous rotation.

[0027] The outer surface of one of the rotating shafts 7 is fixedly connected to the inner wall of the connecting tube 6. The outer surface of each rotating shaft 7 is fixedly connected to a first threaded piece 10. The two first threaded pieces 10 are both located inside the feed box 3. The bottom surface of the support frame 1 is fixedly connected to a support box 19. The bottom surface of the support box 19 is fixedly connected to four bottom plates 20. The support box 19 is used to play a supporting role. In addition, the support box 19 is used to facilitate the storage of line cables and other components.

[0028] The outer surface of each rotating shaft 7 is fixedly connected to the cutter shaft 11, the outer surface of each rotating shaft 7 is fixedly connected to the grinding shaft 12, the outer surface of each rotating shaft 7 is fixedly connected to the spline shaft 13, the front of the limit box 4 is fixedly connected to the mounting plate 21, the outer surfaces of the two rotating shafts 7 are rotatably connected to the inner wall of the mounting plate 21, and the mounting plate 21 is used to seal the limit box 4 to ensure that the material inside the limit box 4 is not easy to leak out.

When the rotating motor 5 rotates, it can drive one of the rotating shafts 7 to rotate, and the two rotating shafts 7 are synchronously rotated by two gears 8 and a synchronous belt 9. At this time, the material is lowered from the feed barrel 16. At this time, the two rotating shafts 7 can respectively use the first threaded piece 10 to push the material that has just fallen forward. At this time, the inside of the limit box 4 is in a high temperature state, and the material slowly melts in the process of being pushed. The first thing it contacts is the cutter shaft 11, which further cuts the material that has not been completely melted, and then it is pushed to the grinding shaft 12. At this time, the two sets of grinding shafts 12 are used to grind the material back and forth against each other to completely and fully grind the material, ensuring that it is not easy for particles to remain, thereby ensuring the quality of the downstream and reducing the loss to the equipment. After that, the spline shaft 13 and the push shaft 14 are used to fully mix the material, and finally the second threaded piece 15 is used to continue to push the material forward for the next step of production.
