[0002] In the plastic products industry, the commonly used uniform hot air drying device is a device used to quickly dry plastic products. This drying device usually uses hot air as a heat source, and evenly blows the hot air to the surface of the plastic product to accelerate the evaporation of water and achieve the drying effect. The uniform hot air drying device is widely used in the plastic products industry and can be used to dry various plastic products, including plastic films, plastic sheets, plastic containers, etc., which can greatly shorten the drying time of plastic products. The existing technology has the following problems:
[0003] During the hot air drying process of plastic products, plastic odor may sometimes be generated. This is mainly because under high temperature, additives, solvents or other volatile components in the plastic material will be heated and released, resulting in odor.
[0004] At present, most of the hot air drying of plastic products adopts assembly line to dry plastic products. The bottom of the plastic product cannot be effectively dried because it is placed on the conveying mechanism, and it is difficult to achieve uniform drying. In addition, the open drying device also causes a large amount of heat source loss, poor drying effect, and uneven drying.
[0005] At present, in order to solve the odor problem in the plastic drying process, the temperature in the drying room is lowered to reduce the release of volatile components in the plastic material, thereby reducing the generation of odor, but lowering the temperature will prolong the drying time.
[0006] A uniform hot air drying device is now proposed to solve the above problems. Utility Model Content

[0011] A further improvement of the technical solution of the utility model is that: the fixing mechanism is provided with two groups, and the turning plate is rotatably mounted on the inner wall of the drying box.
[0012] A further improvement of the technical solution of the utility model is that a hot air generator is slidably mounted on the track, a hydraulic cylinder is fixedly mounted on the top of the hot air generator, and a blowing head is provided at the bottom of the hot air generator.
[0013] A further improvement of the technical solution of the utility model is that the top of the hydraulic cylinder is fixedly connected to the top inner wall of the drying box.

[0029] In this embodiment, the uniform hot air drying device is of sealed design, which reduces heat loss during drying and has higher drying efficiency. When drying plastic products, first open the glass door 2 and place the plastic products in front of the two sets of fixing mechanisms 5 on the inner wall of the drying box 1. At this time, the gasket 53 is pushed by the electric push rod 52 to clamp the two sides of the plastic products, which is compatible with plastic products of different sizes and shapes. Then the flip motor 54 drives the meshed flip disk 51 to rotate on the inner wall of the drying box 1, thereby driving the plastic products clamped and fixed by the gasket 53 to flip, and cooperate with the air-drying mechanism 3 on the top to evenly dry the plastic products, thereby preventing the bottom of the plastic products from not being dried.
[0030] like Figure 3 As shown, the utility model provides a technical solution: preferably, the air-drying mechanism 3 includes a track 31, a hot air generator 32 is slidably installed on the track 31, a hydraulic cylinder 33 is fixedly installed on the top of the hot air generator 32, a blowing head 34 is provided at the bottom of the hot air generator 32, and the top of the hydraulic cylinder 33 is fixedly connected to the top inner wall of the drying box 1.
[0031] In this embodiment, the gasket 53 is pushed by the electric push rod 52 to clamp the two sides of the plastic product, and then the flip motor 54 drives the meshed flip disk 51 to rotate on the inner wall of the drying box 1, driving the gasket 53 to flip the plastic product clamped and fixed. At this time, the hot air generator 32 slidably mounted on the track 31 is pushed down by the hydraulic cylinder 33, so that the blowing head 34 is close to the flipped plastic product. The hot air generator 32 is turned on to spray hot air through the blowing head 34 to air-dry the flipped plastic product. The drying outlet of the uniform hot air drying device and the plastic product can be adjusted in distance to adapt to plastic products of different materials and prevent too close contact from causing a high drying temperature.

[0034] The working principle of the uniform hot air drying device is described in detail below.
[0035] like Figure 1-5As shown, when the uniform hot air drying device is drying plastic products, the glass door 2 is first opened, and the plastic products are placed in front of the two sets of fixing mechanisms 5 on the inner wall of the drying box 1. At this time, the gasket 53 is pushed by the electric push rod 52 to clamp the two sides of the plastic products, which is compatible with plastic products of different sizes and shapes. Then, the flip motor 54 drives the meshed flip disk 51 to rotate on the inner wall of the drying box 1, thereby driving the gasket 53 to clamp and fix the plastic products to flip, and cooperate with the air-drying mechanism 3 on the top to evenly dry the plastic products to prevent the bottom of the plastic products from not being dried. The gasket 53 is pushed by the electric push rod 52 to clamp the two sides of the plastic products. Then, the flip motor 54 drives the meshed flip disk 51 to rotate on the inner wall of the drying box 1, driving the gasket 53 to clamp and fix the plastic products to flip, and at this time, the hot air generator 32 slidably mounted on the track 31 is pushed down by the hydraulic cylinder 33, so that the blowing head 34 is close to the flipped plastic products. The hot air generator 32 is turned on to spray hot air through the blowing head 34 to air-dry the turned plastic product. The distance between the drying outlet of the uniform hot air drying device and the plastic product can be adjusted to adapt to plastic products of different materials and prevent high drying temperature caused by being too close. After adjusting the height, it is suitable for plastic products of different sizes. When it is turned over, it will not collide with the air drying mechanism 3, and has stronger compatibility. The uniform hot air drying device solves the problem of plastic odor generated during hot air drying of plastic products by improving the ventilation effect. The ventilation volume in the drying box 1 is increased by three sets of ventilation mechanisms 4, the odor in the box is eliminated, and the attachment of odor to the product is reduced. The ventilation motor 44 drives the ventilation fan 43 to rotate, and the gas in the drying box 1 is discharged through the activated carbon 41. The uniform hot air drying device uses the activated carbon 41 adsorbent in the ventilation mechanism 4 to adsorb volatile components, reduce the release of odor, and effectively avoid the influence of odor on the product.
