Description

Technical Field

[0001] This utility model relates to the field of plastic product processing technology, specifically to a drying device for processing plastic products. Background Technology

[0002] Drying is a crucial step in the processing of plastic products, especially for raw plastic materials or processed plastic products. Removing moisture or volatile substances effectively improves product quality and stability. The function of drying equipment is to evaporate moisture or solvents from the surface of plastic products in a timely manner by heating air or other methods, thereby ensuring the smooth progress of subsequent processing techniques such as injection molding, blow molding, and coating.

[0003] Currently, common plastic drying equipment on the market mainly includes drying boxes, fluidized bed dryers, and hot air drying equipment. However, these traditional drying equipment often have some defects or shortcomings in practical applications. For example, in large-scale production processes, traditional drying equipment usually cannot guarantee uniform heating, resulting in uneven drying of plastic products, with some areas still retaining moisture, affecting the quality of the products; in addition, the drying cycle is long, which can easily lead to low production efficiency and high energy consumption, increasing production costs.

[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a drying equipment for processing plastic products. Utility Model Content

[0005] The purpose of this invention is to provide a drying device for processing plastic products, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A technical solution for drying equipment for processing plastic products includes a base, an insulated outer shell mounted on the base, a heating system, and a hot air circulation system;

[0008] The heat insulation shell is provided with a material outlet on its side, and a material discharge plate that can be pulled out is provided in the material outlet;

[0009] The heating system includes a heater and a heat spreader plate;

[0010] The hot air circulation system includes a cylindrical fan blade driven by a motor through a transmission assembly, a bearing housing, a hot air guide seat, and an air outlet shroud.

[0011] The equipment is also equipped with a controller for controlling the operation of the heating system and the hot air circulation system.

[0012] As a preferred technical solution, the heat spreader is disposed on the side of the heater for uniform heating.

[0013] As a preferred technical solution, the transmission component includes a belt drive mechanism or a gear drive mechanism.

[0014] As a preferred technical solution, the cylindrical fan blade is installed in the base through a bearing housing, and an air inlet pipe is provided on one side of the cylindrical fan blade.

[0015] As a preferred technical solution, the hot air guide seat is installed inside the base to guide the hot air downwards, and the air outlet hood is located below the air outlet to form a directional hot air channel.

[0016] As a preferred technical solution, the controller is also connected to a temperature sensor for real-time monitoring and adjustment of the drying temperature.

[0017] Compared with the prior art, the beneficial effects of this utility model are: by setting up a heat equalization mesh plate to evenly distribute the heat generated by the heater, and combined with a hot air circulation system driven by a cylindrical fan blade, the hot air flows evenly in the drying chamber, which effectively solves the problem of uneven heating in traditional equipment, ensures that all parts of the plastic product are heated evenly, and significantly improves the drying quality and product qualification rate.

[0018] The system employs a highly efficient hot air circulation system, which uses a motor to drive cylindrical fan blades to create forced convection. This accelerates heat transfer and moisture evaporation, significantly shortens the drying cycle, and reduces energy consumption, thereby lowering production costs.

[0019] By integrating the control of the heating system and hot air circulation system with controllers and temperature sensors, precise adjustment of drying temperature and automated operation are achieved, reducing manual intervention, ensuring process stability, and improving production efficiency.

[0024] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution for a drying equipment for processing plastic products: including a base 11, an insulated outer shell 12 disposed on the base 11, a heating system, and a hot air circulation system.

[0026] The heat-insulating outer shell 12 is fixedly installed above the base 11, and a material port 13 is provided on its side. A material discharge plate 14 for pulling out is slidably installed inside the material port 13 to facilitate the insertion and removal of plastic products.

[0027] The heating system consists of a heater 21 and a heat spreader plate 22. The heater 21 is fixedly installed inside the insulation shell 12 on one side. The heat spreader plate 22 is set on the side of the heater 21 and is tightly attached to the heater 21. It is used to distribute the heat generated by the heater 21 evenly and ensure that the heat is evenly distributed in all areas inside the insulation shell 12.

[0028] The hot air circulation system includes a cylindrical fan blade 26 driven by a motor 24 via a transmission assembly 25, a bearing housing 27, a hot air guide seat 28, and an air outlet shroud 29. The motor 24 is fixedly mounted on the outside of the base 11. The transmission assembly 25, using a belt drive or gear drive mechanism, connects one end to the output shaft of the motor 24 and the other end to the cylindrical fan blade 26, transmitting power from the motor 24 to the cylindrical fan blade 26. The cylindrical fan blade 26 is mounted inside the base 11 via the bearing housing 27 and can rotate around its own axis. An air inlet pipe 3 is provided on one side of the cylindrical fan blade 26 to draw in outside air. The hot air guide seat 28 is located inside the base 11, below the cylindrical fan blade 26, and guides the hot air blown out by the cylindrical fan blade 26 downwards. The air outlet shroud 29 is located below the air outlet and cooperates with the hot air guide seat 28 to form a directional hot air channel, allowing hot air to flow evenly inside the insulation shell 12.

[0029] The equipment is also equipped with a controller 23, which is fixedly installed on the outside of the base 11 and electrically connected to the heater 21, the motor 24, and the temperature sensor (not shown in the figure, but included in the connection of the controller 23). The controller 23 is used to control the operation of the heating system and the hot air circulation system. The temperature sensor is located inside the insulation shell 12 and is used to monitor the drying temperature in real time and transmit the temperature signal to the controller 23. Based on the comparison between the preset temperature value and the actual temperature value, the controller 23 adjusts the heating power of the heater 21 and the speed of the motor 24 to achieve precise adjustment of the drying temperature.

[0030] Open the feed inlet 13, place the plastic products to be dried evenly on the feed plate 14, and then close the feed inlet 13 to ensure that the heat insulation shell 12 is sealed.

[0031] The equipment is powered on, and the drying temperature and time are set via controller 23. Controller 23 starts heater 21 and motor 24 according to the set parameters. Heater 21 begins heating, and the generated heat is evenly distributed inside the insulation shell 12 through the heat spreader 22. Simultaneously, motor 24 drives cylindrical fan 26 to rotate via transmission assembly 25, drawing in outside air from the air inlet duct 3 to form hot air. This hot air is guided by hot air guide seat 28 and air outlet hood 29, and then flows evenly inside the insulation shell 12 to dry the plastic products.

[0032] During the drying process, the temperature sensor monitors the internal temperature of the insulation shell 12 in real time and transmits the temperature signal to the controller 23. Based on the comparison between the preset temperature value and the actual temperature value, the controller 23 automatically adjusts the heating power of the heater 21 and the speed of the motor 24 to ensure that the drying temperature remains stable within the set range.

[0033] When the drying time reaches the preset value or the plastic product reaches the required degree of drying, the controller 23 automatically stops the operation of the heater 21 and the motor 24. The feed inlet 13 is then opened, and the dried plastic product is removed, completing the drying process.

[0034] After use, turn off the power to the device, clean and maintain it to ensure it operates normally the next time it is used.

[0035] The working principle and usage process of this utility model: After assembling the various components of this solution in sequence, work according to the above implementation methods according to actual needs to complete all working steps.
