Abstract
Description
Technical Field
[0001] The utility model belongs to the field of drying equipment and relates to a drying machine for producing plastic boxes. Background Art
[0002] A dryer for plastic box raw material production is used to remove moisture from plastic pellets during the plastics processing process. It heats the air to generate hot air, which is then fed into the dryer and placed in contact with the plastic pellets. The heat from the hot air is transferred to the plastic pellets, evaporating the moisture. Simultaneously, the hot air carries away the evaporated moisture, achieving the desired drying effect.
[0003] The plastic granules for making plastic boxes are put into the raw material drying barrel for drying. During the drying process, if there is no stirring device, the granules in a static state are prone to uneven heating. The part close to the heat source may be over-dried, while the granules inside or far away from the heat source are not dried sufficiently, resulting in uneven overall drying efficiency. Therefore, it is necessary to design a dryer for plastic box production with a more uniform and comprehensive drying process to solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to provide a dryer for producing plastic boxes with splashing treatment function in order to solve the above problems in the prior art.

[0022] The connecting transverse axis 10 is slidably connected to the wave groove 7 , and the output end of the electric push rod 8 is fixedly connected to a spherical ring block 11 .
[0023] The lower end of the vertical stirring rod 9 is fixedly connected to an arc-shaped circular groove connecting block 12 , and the arc-shaped circular groove connecting block 12 is rotatably connected to the spherical ring block 11 .
[0024] A motor 4 is fixedly connected to the lower end of the raw material drying barrel 1 , and an output end of the motor 4 extends into the raw material drying barrel 1 .
