Description

Technical Field

[0001] This utility model relates to the field of precision molding production technology, and in particular to a high-efficiency drying device for precision molding production. Background Technology

[0002] A precision molding drying device is a specialized drying equipment for plastics before molding. It aims to improve the drying effect of plastic granules and ensure the quality of plastic products. This device typically includes components such as a drying tank, a rotating drum, spiral blades, heating elements, a dehumidifier, and a filtration mechanism. Its working principle involves heating and drying the plastic granules through the heating elements, while the dehumidifier removes the generated moisture. The air is then dried by the filtration mechanism before re-entering the drying tank, thus improving drying efficiency and effectiveness. This drying device is widely used in the plastics processing industry, especially in injection molding, extrusion, and blow molding. Its advantages include: High-efficiency drying: The rotating drum design ensures uniform heating of the plastic granules, improving drying efficiency; Energy saving and environmental protection: The reasonable structural design reduces energy consumption and meets environmental protection requirements; Improved product quality: Thoroughly dried plastic granules reduce quality problems such as curling and bubbles in the finished products, improving overall product quality.

[0003] Existing equipment, such as CN215571796U, is a high-efficiency drying device for precision molding production, belonging to the field of precision molding production. This device includes a drying tank with a rotating drum inside. A spiral blade is fixedly connected to the outer side of the rotating drum. A receiving cavity is formed on the rotating drum, and a heating tube is fixedly installed inside the receiving cavity. A dehumidifier is fixedly installed at the top of the drying tank, and a filtration mechanism is fixedly connected to the right side of the bottom of the drying tank. In this invention, after plastic granules are poured into the drying tank, the heating tube in the receiving cavity heats and dries the plastic granules. The generated moisture is removed by the dehumidifier. Then, external air, after being dried by the filtration mechanism, enters the drying tank. When the rotating drum rotates, it can turn the plastic granules at the bottom upwards, facilitating the upward floating of moisture, improving drying efficiency and effect, and increasing the efficiency of precision molding production.

[0004] When workers need to dry materials, they put the materials into the drying device so that the device can dry them. The drying device in the comparison document uses a material conveying method to dry the materials during use. However, because the materials are piled up, some of the materials will have water stains on their surface, which will prolong the drying time for workers. Utility Model Content

The connecting rod 32 is located inside the material tank 1. A strainer 31 is fixedly connected to the bottom end of the connecting rod 32. The strainer 31 is slidably connected to the inner wall of the material tank 1.

[0025] Specifically, a support frame 34 is fixedly connected to the surface of the material tank 1, the drive motor 33 is fixedly connected to one side of the support frame 34, and the rotating end of the rotating wheel 35 is rotatably connected to the inside of the support frame 34. The support frame 34 can cooperate with the material tank 1 to support the drive motor 33 and the rotating wheel 35.

[0026] Specifically, the surface of the material tank 1 is provided with an auxiliary device 4, which includes a guide groove 46, which is opened on one side of the material tank 1.

[0027] In this embodiment, the guide groove 46 can cooperate with the material tank 1 to guide the slider 45.

[0028] In this embodiment: a slider 45 is slidably connected inside the guide groove 46, and a sealing sleeve 44 is fixedly connected to one side of the slider 45. The mesh 31 is placed inside the sealing sleeve 44. The slider 45 can cooperate with the guide groove 46 and the sealing sleeve 44 to achieve the purpose of adjusting the sealing sleeve 44.

[0029] Specifically, a cylinder 41 is fixedly connected to the surface of the material tank 1, and the driving end of the cylinder 41 is fixedly connected to the lower surface of the slider 45.

[0030] In this embodiment, the cylinder 41 can cooperate with the material tank 1 to support the cylinder 41 and adjust the slider 45.

[0031] Specifically, the bottom of the material tank 1 is provided with multiple storage holes 42, which are located above the sealing sleeve 44. The storage holes 42 can cooperate with the material tank 1 to achieve the purpose of storing the insertion rod 43.

Sealing sleeve 44 then slides down, activating dewatering device 3, which uses screen 31 to flush out the material. This auxiliary device 4 significantly improves the efficiency of material unloading, preventing time-consuming processes.
