Abstract
Description
Technical Field
[0001] This utility model belongs to the field of plastic pellet technology, and specifically relates to a cooling device for manufacturing plastic pellets. Background Technology
[0002] In the manufacturing process of plastic granules, the cooling process is a key step to ensure product quality and production efficiency. After extrusion molding, plastic granules are usually in a high-temperature state and need to be cooled down quickly by a cooling device to avoid deformation or sticking of the granules. Traditional cooling methods mainly use air cooling or water cooling, but these methods have problems such as low cooling efficiency and easy formation of water bubbles on the surface of the granules, which affect product quality.
[0003] In existing cold water cooling devices, plastic granules are immersed in cooling water to rapidly cool them down using the thermal conductivity of water. However, water bubbles easily form on the surface of the granules, affecting their appearance and subsequent processing. The granules tend to accumulate in the water, resulting in uneven cooling. Furthermore, low-density plastic granules cannot sink into the cooling water, leading to poor cooling performance. To address these issues, we have designed a cooling device for plastic granule manufacturing to provide an alternative technical solution. Utility Model Content

Detailed Implementation
[0022] 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.
[0023] Reference Figure 1-7 A cooling device for manufacturing plastic granules includes a cooling box 1, a feeding pipe 2 on the top of the cooling box 1, a discharge port 5 at one end inside the cooling box 1, a rotatable circular rotating disk 7 inside the cooling box 1, a plurality of material troughs inside the circular rotating disk 7, and a stirring mechanism inside the material troughs.
[0024] The interior of the cooling box 1 is filled with coolant. An industrial refrigeration unit 3 is installed at the bottom of the cooling box 1. A refrigeration box 6 is fixed to one side of the cooling box 1. A cooling rod 10 is installed inside the refrigeration box 6. Multiple heat dissipation fins 11 are evenly distributed on the outer side of the cooling rod 10. The industrial refrigeration unit 3 is connected to the cooling rod 10 through a pipe. The industrial refrigeration unit 3 is a refrigeration device used in industrial environments. It is widely used in food processing, chemical industry, pharmaceutical industry, cold chain logistics, electronic manufacturing and other fields. It absorbs heat and discharges it to the external environment to maintain a low temperature environment or cool industrial equipment. In this way, it can always keep the coolant inside the cooling box 1 at a low temperature. Through the arrangement of the heat dissipation fins 11, the low temperature of the cooling rod 10 can be effectively guided, which can effectively reduce the temperature of the coolant inside the cooling box 1.
[0025] Multiple rectangular pusher plates 9 are slidably connected inside the circular rotating disk 7. The rectangular pusher plates 9 are located inside the material trough and are slidably connected to the circular rotating disk 7 through the material trough, so that the rectangular pusher plates 9 can move inside the material trough, thereby allowing the plastic particles inside the material trough to be pushed out of the cooling box 1 by the rectangular pusher plates 9, so that the cooled plastic particles can be discharged.
[0026] Multiple water-permeable holes are evenly distributed on both sides of the material tank, so that the coolant inside the cooling box 1 can enter the interior of the material tank through the water-permeable holes, thereby cooling the plastic particles inside the material tank.
[0027] A first drive motor 4 is bolted to the side of the cooling box 1 away from the refrigeration box 6. The output end of the first drive motor 4 passes through the interior of the cooling box 1 and is rotatably connected to the cooling box 1 through a bearing. The output end of the first drive motor 4 is fixedly connected to the circular rotating disk 7, so that the operation of the first drive motor 4 can drive the circular rotating disk 7 to rotate inside the cooling box 1. This allows multiple material troughs inside the circular rotating disk 7 to pass through the bottom of the feeding pipe 2 in sequence. Similarly, multiple material troughs can pass through the discharge port 5 in sequence, so that the plastic granules inside the material troughs can be discharged.
[0028] The stirring mechanism includes a U-shaped fixing plate 13. The bottom of the rectangular pusher plate 9 is fixed with the U-shaped fixing plate 13. The second drive motor 14 is fixed inside the U-shaped fixing plate 13 by bolts. Both ends of the rectangular pusher plate 9 are rotatably connected to the vertical rotating column 12 through bearings. The outer side of the bottom of the vertical rotating column 12 is fixed with a driven gear 15. The two driven gears 15 are meshed. Multiple stirring rods are evenly distributed on the outer side of the top of the vertical rotating column 12. The output end of the second drive motor 14 is fixedly connected to one of the vertical rotating columns 12.
[0029] Here, the operation of the second drive motor 14 enables one of the vertical rotating columns 12 to rotate. Through the meshing connection of two driven gears 15, both vertical rotating columns 12 can rotate, and the two vertical rotating columns 12 rotate in opposite directions. This causes the stirring rods on the outside of the two vertical rotating columns 12 to rotate. When the two vertical rotating columns 12 are in the coolant inside the cooling tank 1, the rotation of the two vertical rotating columns 12 can stir the plastic particles inside the material tank, so that the plastic particles can better contact the coolant, reduce the air bubbles on the surface of the plastic particles, and improve the cooling efficiency of the plastic particles.
[0030] Multiple hydraulic cylinders 8 are evenly distributed inside the cooling box 1. The output end of the hydraulic cylinder 8 is fixedly connected to the U-shaped fixed plate 13, so that the operation of the hydraulic cylinder 8 can drive the U-shaped fixed plate 13 to move, which in turn can drive the rectangular pusher plate 9 to move, so that the movement of the rectangular pusher plate 9 can push out the material inside the material tank.
[0031] Here, the operation of the first drive motor 4 causes the circular rotating disk 7 to rotate, allowing the material tank inside the circular rotating disk 7 to pass through the interior of the cooling box 1 in sequence, so that the plastic particles inside the material tank can be immersed in the coolant, and the floating plastic particles can be completely immersed in the coolant, thereby improving the cooling efficiency of the plastic particles. When the cooled plastic particles rotate to the discharge port 5, the operation of the hydraulic cylinder 8 allows the plastic particles inside the material tank to be discharged.
[0032] Working principle: The operation of the first drive motor 4 causes the circular rotating disk 7 to rotate, allowing the material tank inside the circular rotating disk 7 to pass through the interior of the cooling tank 1 in sequence. This allows the plastic particles inside the material tank to be immersed in the coolant, ensuring that the floating plastic particles are completely immersed in the coolant, thereby improving the cooling efficiency of the plastic particles.
[0033] The operation of the second drive motor 14 enables one of the vertical rotating columns 12 to rotate. Through the meshing connection of two driven gears 15, both vertical rotating columns 12 can rotate, and the two vertical rotating columns 12 rotate in opposite directions. This causes the stirring rods on the outside of the two vertical rotating columns 12 to rotate. When the two vertical rotating columns 12 are in the coolant inside the cooling tank 1, the rotation of the two vertical rotating columns 12 can stir the plastic particles inside the material tank, so that the plastic particles can better contact the coolant, reduce the air bubbles on the surface of the plastic particles, and improve the cooling efficiency of the plastic particles.
[0034] The rotation of the circular rotating disk 7 causes the cooled plastic granules to rotate to the discharge port 5. The operation of the hydraulic cylinder 8 allows the plastic granules to be pushed out of the interior of the cooling box 1 by the rectangular pusher plate 9, so that the plastic granules inside the material tank can be discharged.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
