Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic particle production equipment, in particular to a cooling device for plastic granulation. Background Art
[0002] The production process of plastic pellets includes raw material preparation and processing, mixing and feeding, granulation and extrusion, cooling and pelletizing, post-processing and packaging, as well as quality control and testing. Among them, cooling is to cool the plastic strips extruded from the mold through a water tank to solidify them into shape. The current process is to use a pelletizer to pelletize the plastic strips after cooling and solidifying them. However, the plastic strips will bring the cooling water into the pelletizer together. Over time, it is easy to cause the pelletizer to rust, affecting the service life of the equipment. Therefore, further improvements to the cooling equipment are needed. Utility Model Content
[0003] In view of the above technical problems, the utility model provides a cooling device for plastic granulation which can dry the cooled plastic strips.
[0004] In order to solve the above technical problems, the utility model provides a cooling device for plastic granulation, comprising an extruder, a cooling pool, and a granulator. The cooling pool is arranged between the extruder and the granulator, and a first limiting rod and a second limiting rod are rotatably connected to the lower part of the cooling pool. A support seat is further provided between the cooling pool and the granulator, and a drain cover is fixedly connected to the top of the support seat at one end close to the cooling pool, and a plurality of through holes are opened on the drain cover. A drying device is fixedly connected to the top of the support seat at one end close to the granulator;
[0005] The drying device includes a bracket, which is a frame-shaped structure. The top and bottom of the bracket are fixedly connected to guide rods, the other end of the guide rod is fixedly connected to a push plate, a spring is sleeved on the guide rod, and the guide rod is a sleeved retractable structure. Two drying rollers are arranged between the push plates, and the two ends of the drying rollers are fixedly connected to main shafts, and the main shafts are in contact with the push plates.
[0006] Furthermore, the drain cover is in the shape of a bottomless terrace.
[0007] Furthermore, a water-absorbing cloth is wound around the drying roller.
[0008] Compared with the prior art, the present invention has the following advantages:
[0009] The utility model arranges a drainage cover and a drying device between the cooling pool and the pelletizer to drain and dry the cooled and solidified plastic strips, thereby preventing water in the plastic strips from directly entering the pelletizer for pelletizing and causing rust in the pelletizer, thereby increasing the service life of the device.

[0015] The present invention will be further described below with reference to the accompanying drawings.
[0016] like Figures 1 to 4 A plastic granulation cooling device shown includes an extruder 1, a cooling pool 2, and a granulator 3. The cooling pool 2 is arranged between the extruder 1 and the granulator 3. A first limiting rod 4 and a second limiting rod 5 are rotatably connected to the lower part of the cooling pool 2. A support base 6 is further provided between the cooling pool 2 and the granulator 3. A drain cover 7 is fixedly connected to the top of the support base 6 near the cooling pool 2. The drain cover 7 has a plurality of through holes to facilitate the passage of plastic strips. A drying device 8 is fixedly connected to the top of the support base 6 near the granulator 3.
[0017] The drying device 8 includes a bracket 9, which has a frame-shaped structure. The top and bottom of the bracket 9 are fixedly connected to a guide rod 10. The other end of the guide rod 10 is fixedly connected to a push plate 12. A spring 11 is sleeved on the guide rod 10. The guide rod 10 is a sleeved retractable structure. Two drying rollers 14 are arranged between the push plates 12. The plastic strip passes between the two drying rollers 14. The two ends of the drying rollers 14 are fixedly connected to a main shaft 13, and the main shaft 13 is in contact with the push plate 12.
[0018] In order to facilitate the return of the water drained from the plastic strips to the cooling pool 2, the drain cover 7 is in the shape of a bottomless terrace.
[0019] In order to absorb the cooling water and facilitate replacement, a water-absorbing cloth is wound around the drying roller 14 .
[0020] The working process of this embodiment is as follows:
[0021] After the plastic strips are extruded from the extruder 1, they enter the cooling pool 2 for cooling. The first limiting rod 4 and the second limiting rod 5 play a limiting role, so that the plastic strips can pass under the first limiting rod 4 and the second limiting rod 5 to ensure the cooling effect of the plastic strips. After cooling, the plastic strips pass through the through holes on the drain cover 7 to complete the drainage. The drained water returns to the cooling pool 2 along the drain cover 7. The drained plastic strips pass through two drying rollers 14. The drying rollers 14 are wound with absorbent cloth to absorb the moisture on the plastic strips by contact. Finally, the dried plastic strips enter the pelletizer for pelletizing.
