Description

Technical Field

[0001] This invention relates to the field of granulation equipment technology, specifically a granulation equipment developed based on semi-transparent beaded foam material. Background Technology

[0002] Translucent beaded foam materials have been widely used in medical devices, packaging, automotive interiors and other fields due to their unique physical properties, such as lightweight, heat insulation and cushioning. Translucent beaded foam materials need to be granulated to facilitate subsequent development and production.

[0003] A search revealed Chinese patent CN221604863U, which discloses a polystyrene foam material recycling and granulation device. By setting two pairs of mutually perpendicular first and second spiral blades, and making each pair of spiral blades mesh with each other, the polystyrene foam material can be fully crushed when it is filled, thereby accelerating the rate of heating and melting of the polystyrene foam material. The water-cooling component has a better cooling and plasticizing effect on the molten polystyrene material, and the sliding shaft acts on the molten polystyrene material, making its transfer efficiency faster during recycling.

[0018] Secondly, this invention employs a multi-stage cooling system with spiral blades, heat exchange plates, a rectangular frame, and a sliding block. The system utilizes the synergistic effect of spiral blades, heat exchange plates, and conical holes. The water inflow is adjusted according to the change in the particle size of the material, ensuring that the material is fully cooled during the conveying process.

The size of the conveying roller 26 and the support roller 39 is adapted to the size of the conveying hole.

[0037] Furthermore, the upright is slidably connected to the inner wall of the fixed frame 4. A guide roller 7 is rotatably mounted on one side of the bottom inner wall of water tank 6, and a guide roller 8 is rotatably mounted on one side of the top inner wall of water tank 6. The guide roller 8 is adapted to the size of the limiting plate 28. An inclined surface is provided on one side of the bottom outer wall of the limiting plate 28. Water tank 9 is arc-shaped, and a motor 10 is installed on the inner wall of water tank 9. One end of the output shaft of motor 10 is connected to a rotating rod 14 via a coupling. A breaking blade 15 is installed on one side of the outer wall of the rod 14. A protective cover 12 is fixedly connected to one side of the outer wall of the water tank 2 9.

A discharge hole is opened on one side outer wall of the protective cover 12. The size of the discharge hole is adapted to the conveying hole. The spiral blade 17 is set so that the cooling water flows evenly on the outer wall of the conveying barrel 16, and makes more sufficient contact with the heat exchange plates 37 of the conveying barrel 16 for cooling treatment, so that the cooling process is more efficient. The process is more efficient, ensuring that the material can be cooled quickly and evenly during the conveying process. The second screen plate 20 is slidably connected to the groove of the first screen plate 19 by a slider, ensuring that the two will not separate under force during the granulation process. The protective cover 12 shields the crushing knife 15 and also shields the crushed material to improve the safety performance of the structure. The cooperation of the limiting plate 28 and the guide roller 28 can press and knead the material to further ensure the uniformity of the material size. A lip seal ring seat is set at the orifice where the sliding rod 31 passes through the water tank 29. Its inner diameter is slightly larger than the diameter of the sliding rod 31. A spring is installed in the lip seal ring to provide continuous pre-tightening force to ensure that the seal ring and the sliding rod 31 are in close contact to form a reliable sealing interface.

[0039] Working principle: During the granulation process of translucent beaded foam material, the raw material is fed into the heating chamber 2 for heating treatment, and then conveyed to the discharge pipe 3 for output. The heated molten material is extruded through the overlapping waist-shaped holes 21 on the mesh plate 19 and mesh plate 20. The strip-shaped material is manually pulled by the worker into the water tank 6. When entering the water, it passes through the middle of the guide roller 28 and the limiting plate 28, and then passes around the guide roller 7 and is fed into the conveying barrel 16. The conveying roller 26, together with the support roller 39 on the auxiliary frame 38, conveys the extruded material. The material moves to the other side in the conveying hole of the conveying barrel 16, and finally moves out of the protective cover 12. The motor 10 controls the rotating rod 14 to rotate, thereby controlling the crushing blade 15 to cut and granulate the output material. When the granulation size needs to be adjusted, the electric push rod 5 is activated to control the sliding frame 22 to move, and the screen plate 20 rises and falls accordingly. The more the screen plate 20 overlaps with the waist-shaped hole 21 of the screen plate 19 when it rises, the larger the size of the extruded material. At this time, the support 24 rises accordingly, driving the conveying roller 26 to rise and increase the distance between it and the support roller 39. At the same time, the limiting plate 28 also rises with the movement of the fixed rod 27. The increased distance between the limiting plate 28 and the guide roller 28 accommodates the increased size of the material, and the material passes between the guide roller 28 and the limiting plate 28. The material is pressed and kneaded by the limiting plate 28 and the guide roller 28, then passes around the guide roller 17 and is fed into the conveying barrel 16 by the conveying roller 26 and the support roller 39. Conversely, when a smaller size of material is needed, the electric push rod 5 controls the sliding frame 22 to descend, the overlapping part of the waist-shaped hole 21 is reduced, the extruded size of the material is reduced, and the guiding and conveying structure is also changed to adapt to the material with a changed size. When the material moves in the conveying barrel 16, the water in the water tank 29 enters the cooling cylinder 18 through the water inlet pipe 32 under the action of the pump body 13, and flows through the cooling cylinder 18 along the channel set by the spiral blade 17. It works with the heat exchange plate 37 to feed the material moving in the conveying hole in the conveying barrel 16. The cooling process is a step-by-step cooling system. After absorbing heat, the cold water returns to the water tank 2 9 through the outlet pipe 36. The cold water enters the cooling cylinder 18 through the inlet pipe 32. When the mesh plate 20 rises and the material size increases, requiring more heat dissipation, the support plate 23 rises accordingly. The sliding rod 31 drives the sliding block 30 in the rectangular frame 29 to move. The more the conical hole 33 overlaps with the inlet pipe 32, the more water is introduced, thereby increasing the cooling effect of the cold water in the cooling cylinder 18. When the material size decreases, the sliding block 30 slides and descends in the rectangular frame 29. The overlap between the conical hole 33 and the inlet pipe 32 decreases, reducing the water introduction and adapting to the cooling process of materials with smaller sizes.

[0040] A heat exchanger 11 is installed at the top of water tank 2 9 to exchange heat with the cooling water after it absorbs heat, thereby reducing the temperature and ensuring a continuous cooling effect. Motor 10 drives the rotating rod 14 to rotate, which in turn drives the crushing blade 15 to rotate and cut and granulate the material. At the same time, the stirring frame 34 is driven to rotate through the bevel gear set 35, thereby stirring the cooling liquid inside water tank 2 9 to ensure a more uniform heat distribution and ensure the cooling effect of the material. The spiral blade 17 is set so that the cooling water flows evenly on the outer wall of the conveying barrel 16 and makes more full contact with the heat exchange plate 37 of the conveying barrel 16 for cooling treatment, making the cooling process more efficient and ensuring that the material can be cooled quickly and evenly during the conveying process. The screen plate 20 is slidably connected to the groove of the screen plate 19 through the slider to ensure that the two will not separate under force during the granulation process. The protective cover 12 shields the crushing blade 15 and also shields the crushed material to improve the safety performance of the structure. The cooperation of the limiting plate 28 and the guide roller 28 can press and knead the material to further ensure the dimensional uniformity of the material.
