Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic processing equipment, specifically to a plastic particle cooling mechanism that improves shaping efficiency. Background Technology
[0002] In the plastic granulation process, after molten plastic is extruded and granulated, it needs to be rapidly cooled to a stable temperature to achieve shaping. Currently, common cooling methods include natural cooling, water bath cooling, and air cooling. However, these methods suffer from problems such as slow cooling speed, uneven cooling, and easy particle agglomeration, which leads to extended molding cycles, unstable product quality, and even defects such as adhesion and deformation, seriously affecting the molding efficiency and appearance quality of plastic particles.
[0003] To address these issues, some industry professionals have suggested using spray systems or high-power air-cooling equipment for cooling. While this improves cooling speed, the unstable particle aggregation morphology still results in some areas being insufficiently cooled or overcooled. Furthermore, condensate tends to accumulate inside the device during cooling, further impacting operating efficiency and maintenance frequency.
[0004] Therefore, there is an urgent need to design a plastic particle cooling mechanism with a reasonable structure, high cooling efficiency, uniform particle dispersion, and suitability for continuous operation, so as to improve the shaping efficiency and enhance the product quality of plastic particles. Utility Model Content
[0005] The purpose of this invention is to provide a plastic particle cooling mechanism that improves the setting efficiency, thereby solving the technical problems of slow cooling speed, poor setting effect, and easy particle agglomeration in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A plastic particle cooling mechanism for improving shaping efficiency includes a cooling shell, a feeding device, a cooling assembly, a particle dispersion assembly, and a discharging assembly.
[0008] The cooling assembly is located inside the cooling housing and includes a spirally arranged cooling pipe and an annular air-cooled duct surrounding the cooling pipe; the cooling pipe is connected to a circulating coolant supply system, and several fans are installed in the duct.
[0009] The particle dispersion component is located above the cooling pipe and includes a vibrating flow divider and a flow guide baffle to ensure that the particles entering the cooling chamber are evenly distributed in the cooling area and to avoid agglomeration.
[0010] The discharge assembly includes a conical guide tube and a discharge channel, through which cooled particles are discharged.
[0011] Preferably, the lower part of the cooling housing is provided with a condensate collection tank to prevent condensate from accumulating and affecting operation;
[0012] Preferably, the air-cooled duct is equipped with a temperature control mechanism to adjust the cooling air temperature at different stages, thereby achieving precise cooling control.
[0013] Preferably, the flow divider has an adjustable angle structure to adapt to the morphology and particle size of different batches of particles. Attached Figure Description

Detailed Implementation
[0020] Example 1: As Figure 1 As shown, a plastic particle cooling mechanism for improving shaping efficiency includes a cooling shell 1, a feeding device 2, a cooling assembly, a particle dispersion assembly 6, and a discharge assembly 9. The cooling shell 1 is a closed structure with a feeding port at the top and a discharge port at the bottom.
[0021] Example 2: Figure 2As shown, the cooling assembly includes spirally arranged cooling pipes 3, made of corrosion-resistant metal, through which a low-temperature circulating coolant flows. The coolant is supplied by an external cooling unit and maintained at a constant temperature. An air-cooled duct 4 is installed around the cooling pipes 3, with fans 5 evenly distributed within the duct to create a ring-shaped, strong convective air-cooled environment, improving the cooling rate. The cooling pipes and air-cooled ducts work together to form a dual cooling environment. While conducting coolant cooling, the duct creates a ring-shaped airflow to enhance heat dissipation efficiency, thereby improving the overall cooling speed and uniformity, and preventing localized overheating or insufficient cooling of particles. To prevent condensation on the surface of the cooling pipes during low-temperature operation, the cooling pipes 3 are covered with an anti-condensation insulation layer. This insulation layer can be made of foamed rubber and plastic materials, PE insulation sleeves, or other heat-insulating materials to achieve heat insulation and reduce condensation generation, improving overall operational stability.
[0022] Example 3: Figure 3 As shown, the particle dispersion component 6 includes a vibrating diverter plate 7 and several guide baffles 8 disposed below the feed inlet. The vibrating diverter plate 7 is driven by an eccentric motor to achieve high-frequency vibration, making the feeding process more uniform. The vibrating diverter plate 7 is disposed in the feed path above the cooling pipe, and it is driven by an eccentric motor to achieve high-frequency lateral micro-motion, effectively breaking up the aggregated particles and dispersing them uniformly. The guide baffles 8 are arranged at equal intervals directly above the cooling component to further control the particle distribution area, avoid concentrated accumulation, and improve cooling uniformity.
[0023] Example 4: Figure 4 As shown, the air-cooled duct 4 is equipped with a temperature control mechanism 13, which can automatically adjust the air-cooled temperature according to the production batch or the required cooling rate, effectively preventing the particles from being "overcooled" or "undercooled", and improving the consistency of shaping.
[0024] Example 5: Figure 5 As shown, the discharge assembly 9 includes a conical guide pipe 10 and a discharge channel 11. The conical guide pipe 10 collects the cooled particles and guides them to the discharge channel 11. The discharge assembly is located at the bottom of the cooling housing and is mainly used to orderly discharge the plastic particles that have completed the shaping and cooling process. The guide pipe 10 has a downward conical design, which facilitates the gravity discharge of particles and ensures continuous discharge. The bottom of the cooling housing 1 is also equipped with a condensate collection tank 12 for centralized discharge of condensate, preventing liquid accumulation from affecting the production environment and equipment operation.
