Description

Technical Field

[0001] The utility model relates to the technical field of plastic particles, in particular to a drying device for processing toy plastic particles. Background Art

[0002] Plastic particles are the common name for plastic granules. They are the raw materials for plastic storage, transportation and processing in the form of semi-finished products. In the process of processing plastic particles, they need to be dried. Plastic drying refers to the removal of water vapor and other volatile substances in plastic raw materials at a temperature where the plastic is continuously heated without deformation. Pre-drying of raw materials has a significant impact on the quality of injection molded products. Before the processing and forming of plastic products, the materials must be fully dried.

[0003] In the process of drying plastic particles in the existing drying device for processing toy plastic particles, the moisture in the plastic particles evaporates with the flowing hot air, taking away some of the plastic microparticles. The air containing the plastic microparticles is directly discharged to the outdoors, which will cause air pollution. Long-term inhalation of air containing plastic microparticles will affect physical health. Therefore, a drying device for processing toy plastic particles is proposed to solve the above-mentioned problems. Utility Model Content

[0027] Specifically, refer to Figure 2 The air outlet of the fan 11 is fixedly connected to an air supply pipe 12 extending to the outside of the fixed box 9, the right side of the air supply pipe 12 is fixedly connected to an air heater 13 extending to the inside of the drying box 1, and a hair dryer 14 is provided on the right side of the air heater 13.

[0028] In this embodiment, when drying the plastic particles inside the drying box 1, the fan 11 conveys the filtered air to the inside of the air duct 12, and enters the inside of the air heater 13 through the air duct 12 to be heated, so that the heated air passes through the hair dryer 14 to dry the plastic particles transported on the conveyor.

[0029] Specifically, refer to Figure 3 A second conveyor 16 is installed on the inner wall of the drying box 1 , a first conveyor 15 located above the second conveyor 16 is installed on the inner wall of the drying box 1 , and a third conveyor 22 located below the second conveyor 16 is installed on the inner wall of the drying box 1 .

[0030] In this embodiment, the plastic particles to be dried are placed on the upper side of the first conveyor 15, and the first conveyor 15 conveys the plastic particles to the front side in a clockwise direction, and the plastic particles fall into the upper side of the second conveyor 16 on the upper side. The second conveyor 16 on the upper side conveys the plastic particles to the rear side in a counterclockwise direction, and the plastic particles fall to the top of the second conveyor 16 on the lower side. The second conveyor 16 on the lower side conveys the plastic particles clockwise and conveys the plastic particles to the front side, and the plastic particles fall to the top of the third conveyor 22. The third conveyor 22 conveys the plastic particles counterclockwise and conveys the plastic particles out of the drying box 1.

[0031] Specifically, refer to Figure 3 There are two second conveyors 16 in number and they are staggered. The upper second conveyor 16 is staggered with the first conveyor 15 , and the lower second conveyor 16 is staggered with the third conveyor 22 .

[0033] In this embodiment, the plastic particles are placed on the top of the first conveyor 15, and the first conveyor 15 conveys the plastic particles to the interior of the drying box 1 through the feeding port 17. The plastic particles are conveyed inside the drying box 1, fall to the upper side of the third conveyor 22, and are conveyed by the third conveyor 22, and are conveyed out of the drying box 1 through the discharge port 18.

[0034] Specifically, refer to Figure 4The right side of the filter box 3 is rotatably connected to a worm gear 19 fixedly connected to the filter cartridge 4, the right side of the filter box 3 is fixedly connected to a motor 21, the output shaft of the motor 21 is fixedly connected to a worm 20 rotatably connected to the right side of the filter box 3, and the worm gear 19 is meshed with the worm 20.

[0035] In this embodiment, when there is a lot of dust and impurities on the outside of the filter cartridge 4, the filter cartridge 4 is blocked, affecting air filtration and stopping the drying effect on the plastic particles. The motor 21 is started, the motor 21 drives the worm 20 to rotate, the worm 20 drives the worm gear 19 to rotate, and the worm gear 19 drives the filter cartridge 4 to rotate. When the filter cartridge 4 rotates, the brush 5 brushes the outside of the filter cartridge 4, so that the dust and impurities on the outside and inside of the filter cartridge 4 are brushed off.

[0036] Working principle:

[0037] First, the plastic particles are placed on the first conveyor 15 for conveying to the interior of the drying box 1, and the fan 11 is started. The fan 11 sucks the air inside the drying box 1 into the interior of the connecting pipe 2 and enters the filter box 3. The air is filtered through the filter cartridge 4 and enters the interior of the fixed pipe 10, and enters the air delivery pipe 12 through the fan 11, and enters the air heater 13 for heating through the air delivery pipe 12. The hot air dries the plastic particles inside the drying box 1 through the blower 14. The plastic particles first fall from the first conveyor 15 to the upper second conveyor 16 and are conveyed counterclockwise to the lower second conveyor 16. The lower second conveyor 16 conveys the plastic particles clockwise and conveys the plastic particles to the third conveyor 22. The third conveyor 22 conveys the plastic particles counterclockwise out of the drying box 1.

[0038] Then: when there is a lot of dust and impurities outside the filter cartridge 4, stop drying the plastic particles 1, start the motor 21, the motor 21 drives the worm 20 to rotate, the worm 20 drives the worm gear 19 to rotate, and the worm gear 19 drives the filter cartridge 4 to rotate, so that the dust inside the filter cartridge 4 is brushed off by the brush 5 and falls into the inside of the material receiving bucket 7 for collection. When a lot of dust is collected, remove the material receiving bucket 7 and pour out the dust.
