Description

Technical Field

[0001] The utility model relates to the technical field of twin-screw extruders, in particular to a wire-splitting device of a twin-screw extruder. Background Art

[0002] The twin-screw extruder is developed on the basis of the single-screw extruder. Due to its good feeding performance, mixing and plasticizing performance, exhaust performance, extrusion stability and other characteristics, it has been widely used in the molding processing of extruded products.

[0003] After searching, the patent (application number: 202322653662.6) discloses "a wire separation device for a twin-screw extruder". The device has the problem of insufficient contact between the flat wire and the cooling water body, which produces a double cooling effect on the twin-screw extruder ribbon. However, the device has the following problems during use:

[0004] First, the hollow column in the device is mainly responsible for confining the ribbon in the water for cooling. However, the hollow column adopts a pipe-type hollow structure, and according to the attached figure, both ends of the hollow column are bent upward. The temperature of the ribbon after being extruded from the double-screw extruder is very high, so it is very difficult to pass through the hollow column.

[0005] In addition, the wind blown by the fan can only act on the ribbon, but as the ribbon continues to be transported, if the water in the pool only relies on natural cooling, the water temperature will continue to rise and the cooling effect will continue to weaken. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides a wire separation device for a twin-screw extruder, which overcomes the deficiencies of the prior art and effectively solves the problems of great difficulty in the passage of the ribbon and weakened cooling effect.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A wire separation device for a twin-screw extruder comprises a cold water pool, the inner wall of the cold water pool is rotatably connected to a guide frame, and the inner wall of the guide frame is fixedly connected to guide rods distributed at equal distances, a connecting seat is welded to the outer wall of one side of the guide frame, and a cylinder is hinged between the connecting seat and the cold water pool;

[0009] The outer wall at the top of the cold water pool is hinged with symmetrically distributed support frames, and a fan is installed on the inner wall at the top of the support frame. A limiting frame is welded at the bottom of the outer wall at one end of the support frame, and an electric stirrer is installed on the outer wall at the bottom of the cold water pool.

[0010] Preferably, connecting frames are welded to the outer walls on both sides of the cold water pool, and a pressure roller and a guide roller are rotatably connected between the two connecting frames.

[0011] Preferably, a wire separation roller is rotatably connected to one side of the pressure roller between the two connecting frames, and the outer wall of the wire separation roller is provided with wire separation grooves distributed at equal distances.

[0014] Preferably, a drain pipe with a valve is installed on the outer wall of the bottom of the cold water pool.

[0015] Preferably, symmetrically distributed supporting legs are welded to the outer wall of the bottom of the cold water pool.

[0016] The beneficial effects of the utility model are:

[0026] In this embodiment, the ribbon can be immersed in water for cooling under the traction of the guide rod 5. Since the ribbon is directly arranged in the cold water pool 1, it is convenient for the ribbon to pass through the guide rod 5, and the guide rod 5 can be separated from the water surface by pushing the guide frame 4 to rotate through the cylinder 2, which is convenient for cleaning.

[0027] Example 2, refer to Figures 1 to 3 A filament separation device of a twin-screw extruder, a symmetrically distributed support frame 6 is hinged on the top outer wall of a cold water pool 1, and a fan 7 is installed on the top inner wall of the support frame 6, a limiting frame 8 is welded to the bottom of the outer wall of one end of the support frame 6, and an electric stirrer 9 is installed on the bottom outer wall of the cold water pool 1.

[0028] In this embodiment, the fan 7 can be moved to the top of the cold water pool 1 by rotating the support frame 6, so that the heat dissipation area is large, and under the stirring action of the electric stirrer 9, the water in the cold water pool 1 is cooled evenly, which greatly reduces the speed of water temperature rise and can continuously cool the ribbon.

[0029] Reference Figures 1 to 2 A connecting frame 10 is welded to the outer walls of both sides of the cold water pool 1, and a pressure roller 11 and a guide roller 12 are rotatably connected between the two connecting frames 10.

[0035] Working principle: The ribbon will first be discharged from the extrusion port of the double-thread extruder, and then immersed in the cold water pool 1 along the guide rod 5 for cooling, and then pass through the guide rod 5 and be transported to the wire separation roller 13 along the pressure roller 11 and the guide roller 12. Each wire will continue to pass through the wire separation groove of the wire separation roller 13. Since the cylinder 2 is hinged between the guide frame 4 and the cold water pool 1, the guide frame 4 is pushed to rotate by the cylinder 2 to separate the guide rod 5 from the water surface, which is convenient for cleaning. A fan 7 is provided on the top of the cold water pool 1. The fan 7 can blow air toward the water surface, and under the stirring action of the electric stirrer 9, the water in the cold water pool 1 is cooled evenly.
