[0004] Before plasticizing by heating, the raw materials need to be mixed in proportion. However, during the storage or transportation of the raw materials, the raw materials will be affected by the humidity of the air, causing their own weight to increase, resulting in inaccurate proportions, and thus affecting the processing quality. Therefore, the raw materials need to be dehydrated and dried before proportioning. However, when dehumidifying and drying the plastic powder, the plastic powder is heated unevenly, resulting in poor dehumidification effect, and the plastic powder is easily stuck together, affecting the subsequent processing quality. In view of this, we propose a dehumidification and drying device for plastic powder. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Plastic powder refers to powdered plastic. The production of plastic powder is a production process of measuring, mixing, plasticizing and pelletizing polymer resin with various additives and auxiliaries. For details, please refer to Figure 1-Figure 6As shown, this embodiment provides a dehumidification and drying device for plastic powder, including a base 1, a material barrel 10 is fixedly connected above the base 1, a barrel cover 11 is provided above the material barrel 10, a stirring chamber 2 is provided inside the material barrel 10, the stirring chamber 2 is used to hold plastic powder, a stirring component 3 is provided inside the stirring chamber 2, and a shaking component 4 is provided below the stirring chamber 2, and the stirring component 3 and the shaking component 4 are used in combination to dehumidify and dry the plastic powder inside the stirring chamber 2.

[0026] The improvement of this embodiment is that:

[0027] The utility model takes into account that when dehumidifying and drying plastic powder, the plastic powder is heated unevenly, resulting in a poor dehumidification effect, and the plastic powder is easily adhered together, affecting the subsequent processing quality. Therefore, the plastic dust inside the stirring bin 2 is heated by the stirring component 3, and the plastic dust is dehumidified and dried by temperature. The stirring component 3 and the shaking component 4 cooperate to fully dehumidify and dry the plastic powder inside the stirring bin 2, and prevent the plastic powder from adhering during the dehumidification and drying process, thereby improving the working effect.

[0028] Considering the need to dehumidify and dry the plastic particles, a heating rod 301 is provided inside the rotating rod 30, wherein the working principle of the heating rod 301 is as known to those skilled in the art: the heating rod 301 is made of a conductive material, and nickel alloys or iron-chromium-aluminum alloys are usually used as the heating element material. These materials have a high electrical positivity and a high temperature coefficient of resistance, and can generate a large amount of heat when powered on. Secondly, there is a resistance wire wrapped with an insulating material inside the heating rod 301. When a voltage is applied from the outside, the resistance wire will generate heat under the action of the current, thereby causing the heating rod 301 to heat up as a whole. The heating effect of the heating rod 301 is used to heat the plastic powder inside the mixing bin 2 for dehumidification and drying. The heating rod 301 needs to control the temperature to meet the dehumidification and drying functions while avoiding melting the plastic powder. This is something that is easily associated with those skilled in the art and will not be elaborated here.

[0029] Considering that when the plastic powder inside the mixing bin 2 is dehumidified and dried, the temperature inside the mixing bin 2 is too high and may easily cause damage to the plastic powder, a ventilation cover 12 is provided on the surface of the barrel cover 11. By opening the ventilation cover 12, the heat inside the mixing bin 2 can be cooled, thereby avoiding damage to the plastic powder caused by excessive temperature.

[0030] Taking into account that when dehumidifying and drying the plastic powder, the plastic powder is heated unevenly, resulting in a poor dehumidification effect, and the plastic powder is easily adhered together, the stirring component 3 includes a rotating rod 30 inside the stirring bin 2, and a plurality of symmetrical first stirring rods 31 and second stirring rods 32 are evenly distributed on the surface of the rotating rod 30, and a third stirring rod 33 is fixedly connected below the rotating rod 30, and a first motor 34 output shaft is fixedly connected above the rotating rod 30, and a shell of the first motor 34 is fixedly connected to the surface of the barrel cover 11; the shaking component 4 includes a lower base 40 below the stirring bin 2, and the lower base 40 is fixedly connected to the upper part of the barrel 10 below, a support column 41 is fixedly connected to the upper part of the lower base 40, and an upper base 42 is fixedly connected to one end of the support column 41, and a second motor 43 shell is fixedly connected to the lower part of the upper base 42, and a groove 44 is opened above the upper base 42, and a rotating block 45 is rotatably connected inside the groove 44, and the upper bottom A plurality of symmetrical sliding shafts 46 are evenly distributed above the seat 42, and a sliding rod 47 is also provided above the upper base 42. Both ends of the sliding rod 47 slide between the sliding shafts 46, and a groove is opened in the middle of the sliding rod 47 to slide one end of a rotating block 45. When the plastic dust is dehumidified and dried, the plastic dust is placed in the mixing bin 2, and then the mixing component 3 is placed inside the mixing bin 2. The power supply is started to energize the first motor 34 and the second motor 43, and the first motor 34 output shaft drives the first mixing rod 31, the second mixing rod 32 and the third mixing rod 33 to alternately mix inside the mixing bin 2; the second motor 43 output shaft causes one end of the rotating block 45 to rotate inside the sliding rod 47 to shake and vibrate the mixing bin 2, and the mixing component 3 and the shaking component 4 cooperate to achieve uniform heating of the plastic dust inside the mixing bin 2, improve the drying effect, and avoid adhesion of plastic particles during dehumidification and drying, thereby improving the processing effect.

[0031] Among them, the working principle of the motor is as known to people in the technical field: it uses an energized coil to generate a rotating magnetic field and acts on the rotor squirrel cage closed aluminum frame to form a magneto-electric power rotation torque, thereby ensuring that the output shaft of the first motor 34 drives the first stirring rod 31, the second stirring rod 32 and the third stirring rod 33 in the stirring chamber 2 to rotate, and the output shaft of the second motor 43 drives one end of the rotating block 45 to slide in the groove inside the sliding rod 47.

[0032] In summary, the working principle of this solution is as follows:

[0033] The plastic dust is placed in the mixing bin 2, and then the mixing component 3 is placed inside the mixing bin 2, and the power is started to energize the first motor 34 and the second motor 43, and the first motor 34 output shaft drives the first mixing rod 31, the second mixing rod 32 and the third mixing rod 33 to alternately mix inside the mixing bin 2; the second motor 43 output shaft causes one end of the rotating block 45 to rotate inside the sliding rod 47 to shake and vibrate the mixing bin 2, and the mixing component 3 and the shaking component 4 cooperate to achieve uniform heating of the plastic dust inside the mixing bin 2, improve the drying effect, and avoid adhesion of plastic particles during dehumidification and drying, thereby improving the processing effect.
