Description

Technical Field

[0001] This utility model relates to the field of plastic processing equipment technology, specifically a plastic cooling device. Background Technology

[0002] In the production process of plastic products, the temperature of freshly molded plastic products is relatively high, and they need to be cooled before they can enter the subsequent cutting, assembly or packaging processes.

[0003] Currently, most common plastic cooling devices on the market employ either water cooling or air cooling alone. While water cooling offers faster cooling, it easily leads to water droplets forming on the surface of plastic products, requiring an additional drying process. Furthermore, impurities can easily remain in the cooling water, potentially clogging the cooling pipes over time. Air cooling, on the other hand, suffers from low cooling efficiency and poor cooling uniformity. This is particularly problematic for thicker plastic products, where internal heat is difficult to dissipate quickly, leading to deformation, cracking, and other quality issues. Additionally, the temperature control in existing cooling devices is mostly manual, failing to dynamically adjust the cooling intensity based on the real-time temperature of the plastic product. This not only increases labor costs but can also negatively impact product quality due to improper temperature control. Moreover, some cooling devices have poorly designed conveyor mechanisms, causing plastic products to shift or become stuck within the cooling chamber, resulting in inconsistent cooling times and further reducing production efficiency.

[0004] Therefore, a plastic cooling device is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a plastic cooling device that achieves rapid and uniform cooling of plastic products through the synergistic effect of a dual cooling system of "water cooling + air cooling" combined with intelligent temperature control and a stable conveying mechanism. At the same time, it reduces energy consumption and labor costs, and improves product cooling quality and production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plastic cooling device, comprising a cooling box, a cooling cavity, a water cooling system, an air cooling system, a temperature control system, and a conveying mechanism. The cooling cavity is disposed inside the cooling box, and the conveying mechanism passes through the cooling cavity for conveying plastic products to be cooled. The water cooling system is disposed on the surface of the cooling box for cooling the plastic products. The air cooling system is installed on the side surface of the cooling box for accelerating the dissipation of heat from the surface of the plastic products. The temperature control system is used for intelligent control of the device.

The cooling water tank is installed on the outside of the cooling tank body. The cooling water pipes are coiled around the inner wall of the cooling cavity, and the inlet end of the cooling water pipes is connected to the outlet of the cooling water tank through a pipe. The water pump is installed on the pipe at the inlet end of the cooling water pipes. The outlet end of the cooling water pipes is connected to the return water port of the cooling water tank through a return water pipe, forming a water circulation loop. Multiple spray holes are evenly arranged on the cooling water pipes for spraying cooling water into the cooling cavity.

[0008] Preferably, the air-cooling system includes a fan, an air inlet duct, an air outlet duct, and an air guide plate. The fan is located on the outside of the cooling box. One end of the air inlet duct is connected to the air outlet of the fan, and the other end extends into the interior of the cooling chamber. One end of the air outlet duct is connected to the cooling chamber, and the other end extends to the outside of the cooling box. The air guide plate is located inside the cooling chamber and at the air outlet of the air inlet duct.

[0009] Preferably, the temperature control system includes a temperature sensor disposed inside the cooling chamber for detecting the temperature inside the cooling chamber. Controllers are respectively installed on the water pump and the fan. The temperature sensor is electrically connected to the controllers and is used to adjust the speed of the water pump and the wind speed of the fan based on the temperature signal detected by the temperature sensor.

[0017] 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.

[0018] like Figures 1 to 5As shown, this utility model provides a plastic cooling device, including a cooling box 1, a cooling cavity 2, a water cooling system 3, an air cooling system 4, a temperature control system 5, and a conveying mechanism 6. The specific structure and connection relationship of each component are as follows; Cooling chamber 2 is located inside cooling box 1, forming a relatively closed cooling space; conveying mechanism 6 runs through cooling chamber 2 along the length of cooling box 1, used to transport the plastic products to be cooled from the inlet to the outlet of cooling chamber 2, realizing continuous cooling; water cooling system 3 is attached to the surface of cooling box 1 and the inner wall of cooling chamber 2, and achieves rapid cooling through water circulation; air cooling system 4 is installed on the side surface of cooling box 1, used to accelerate the air flow in cooling chamber and promote the dissipation of heat from the surface of plastic products; temperature control system 5 is electrically connected to water cooling system 3 and air cooling system 4 to realize intelligent regulation of the cooling process.

[0019] like Figures 1 to 5 As shown, the water cooling system 3 includes a cooling water tank 31, a cooling water pipe 32, a water pump 33, and a return water pipe 34; the inner wall of the cooling chamber 2 is also provided with a heat-conducting layer with a thickness of 3-5mm. This heat-conducting layer is made of aluminum alloy material with high thermal conductivity. The cooling water pipe 32 is attached to the outside of the heat-conducting layer. The cooling capacity of the cooling water pipe 32 is evenly transferred to the cooling chamber 2 through the heat-conducting layer, thereby improving the cooling uniformity. The cooling water tank 31 is fixedly installed on the outer bottom of the cooling tank body 1. It stores cooling water and has a filter device such as a filter screen or filter element in the middle of the tank to filter impurities in the return water, prevent the cooling water pipe 32 from clogging, and extend the service life of the water circulation system. The cooling water pipe 32 is made of corrosion-resistant stainless steel and is tightly attached to the inner wall of the cooling chamber 2 in a spiral coiled manner. Multiple spray holes with a diameter of 2-3 mm and a spacing of 5-8 cm are evenly opened on the pipe wall of the cooling water pipe 32 to evenly spray atomized cooling water into the cooling chamber 2, avoiding the direct impact of cooling water on plastic products and causing deformation. The inlet end of the cooling water pipe 32 is connected to the outlet of the cooling water tank 31 through a pipe, and a water pump 33 is installed on the inlet pipe to provide power for the cooling water circulation; the outlet end of the cooling water pipe 32 is connected to the return port of the cooling water tank 31 through a return pipe 34 to form a complete water circulation loop, realize the reuse of cooling water, and reduce water consumption.

[0020] like Figures 1 to 5As shown, the air-cooled system 4 includes a fan 41, an air inlet duct 42, an air outlet duct 43, and an air guide plate 44. The fan 41 is a centrifugal fan, which is fixed on one side of the outer wall of the cooling box 1 and is used to deliver cold air into the cooling chamber 2. One end of the air inlet duct 42 is sealed to the air outlet of the fan 41, and the other end extends through the side wall of the cooling box 1 into the interior of the cooling chamber 2. The end of the air inlet duct 42 is flared to expand the air outlet range. One end of the air outlet duct 43 is connected to the top of the cooling chamber 2, and the other end extends to the outside of the cooling box 1 to discharge the hot air that has absorbed heat in the cooling chamber 2, forming an air circulation. The air guide plate 44 is installed inside the cooling chamber 2 and located at the air outlet of the air inlet duct 42. There are 3-5 air guide plates 44 in total, which are evenly distributed in an inclined shape of 30°-60°. Each air guide plate 44 is movably connected to the inner wall of the cooling chamber 2 by bolts. The inclination angle of the air guide plate 44 can be changed by adjusting the tightness of the bolts, thereby adjusting the flow direction of the cold air in the cooling chamber 2 and ensuring that the cold air evenly covers the plastic products on the conveyor belt 63.

[0021] like Figures 1 to 5 As shown, the temperature sensor 51 is a platinum resistance temperature sensor, which is fixedly installed in the middle of the cooling chamber 2, with the sensor probe facing the conveyor belt 63. It is used to detect the air temperature and the surface temperature of the plastic products in the cooling chamber 2 in real time. The water pump 33 and the fan 41 are each equipped with an independent controller, such as a PLC controller. The temperature sensor 51 is electrically connected to the two controllers through wires. When the temperature sensor 51 detects that the temperature in the cooling chamber 2 is higher than the preset value, such as 40°C, the controller will automatically increase the speed of the water pump 33 to increase the cooling water flow and the fan speed of the fan 41 to increase the amount of cold air delivered. When the temperature is lower than the preset value, such as 25°C, the controller will reduce the speed of the water pump 33 and the fan speed of the fan 41 to achieve dynamic adjustment of the cooling intensity and ensure that the cooling temperature is stable within the set range.

[0022] The conveying mechanism 6 includes conveying rollers 61, a drive motor 62, and a conveyor belt 63. Multiple conveying rollers 61 are provided and are evenly distributed at both ends of the cooling chamber 2. The conveyor belt 63 is sleeved on the conveying rollers 61. The drive motor 62 is connected to one of the conveying rollers 61. The conveying mechanism 6 uses multiple conveying rollers 61 to support the anti-slip conveyor belt 63. With an adjustable conveying speed, it can adapt to the conveying needs of plastic products of different specifications, avoid deviation and jamming during the conveying process, and ensure continuous production.

[0023] Working principle and process: Preparation stage: Inject sufficient cooling water into the cooling water tank 31, set the target temperature of the cooling chamber 2, such as 30℃, through the temperature control system 5, and adjust the speed of the drive motor 62 according to the thickness of the plastic product to determine the conveying speed. Conveying and Cooling: Start the drive motor 62, and the plastic product to be cooled enters the cooling chamber 2 through the conveyor belt 63; at the same time, start the water pump 33 and the fan 41, and spray atomized cooling water into the cooling chamber 2 through the water spray hole of the cooling water pipe 32 to initially cool down the plastic product; the fan 41 delivers cold air into the cooling chamber 2 through the air inlet pipe 42, and the cold air is guided by the air guide plate 44 and blown evenly onto the surface of the plastic product to accelerate the evaporation of water droplets and the dissipation of heat, while the hot air is discharged through the air outlet pipe 43; Intelligent temperature control: Temperature sensor 51 detects the temperature inside cooling chamber 2 in real time and transmits the signal to the controller; if the temperature is higher than the target value, the controller automatically increases the speed of water pump 33 and the fan speed of fan 41 to enhance the cooling intensity; if the temperature is lower than the target value, the speed and fan speed are reduced to ensure temperature stability. Circulation and discharge: Cooling water flows back to cooling water tank 31 through return water pipe 34, is filtered by the filter device and then recycled; the cooled plastic products are discharged from the outlet of cooling chamber 2 by conveyor belt 63 and enter the subsequent process.
