Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic particle production, in particular to a plastic particle drying machine. Background Art
[0002] Plastic granules refer to granular plastics, which are generally divided into more than 200 types and subdivided into thousands of types. Common plastic granules include general-purpose plastics, engineering plastics, and special plastics. Before injection molding, the plastic granule raw materials need to be heated and dried to evaporate the moisture on the surface of the plastic granules to prevent the moisture on the plastic granules from causing bubbles in the plastic when the plastic is melted, which affects the quality of the plastic product.
[0003] Firstly, the existing plastic pellet dryer structure generally only has a drying function. Before the plastic pellets are dried, the plastic pellets will contain some moisture, which will increase the drying time of the plastic pellets. There is no drainage mechanism, which makes it inconvenient to pre-dry the moisture in the plastic pellets, thereby reducing the drying efficiency of the dryer. Secondly, since the plastic pellets will pile up together when they are placed in a storage barrel for drying, the plastic pellets located outside will dry faster, while the plastic pellets piled up inside will dry and stir, causing the plastic pellets in the storage barrel to dry unevenly. There is no stirring mechanism, which makes it inconvenient to evenly stir the plastic pellets when drying, thereby reducing the drying effect of the dryer. Utility Model Content

The first motor 25 is started through the draining mechanism 2, and the output end of the first motor 25 drives the worm 24 to transmit, and the worm 24 drives the worm wheel 21 to rotate. The rotation of the worm wheel 21 drives the gear 28 to rotate through the rotating rod 23.

The pipe cover 12 is opened, and the plastic particles to be dried are added to the material storage barrel 13 through the material pipe 11, and then the pipe cover 12 is covered. After the plastic particles are dried, the dried plastic particles are discharged through the material pipe 11 in combination with the discharge port 9 by opening the baffle 10 and the pipe cover 12, and at the same time, the shaker 14 shakes the material storage barrel 13 to facilitate the discharge of the plastic particles.
[0021] A drain pipe 8 used in conjunction with the drain mechanism 2 is provided on one side of the bottom end of the drying box body 1, and a control valve 7 is provided on the top of the drain pipe 8. The control valve 7 is used in conjunction with the drain pipe 8 to drain the water drained from the drying box body 1.
[0022] The outer surface of the storage barrel 13 is hollowed out so that the water on the outer surface of the plastic particles can be drained out when the storage barrel 13 as a whole rotates. At the same time, the holes on the storage barrel 13 are smaller than the size of the plastic particles. The hollow shape also makes it easier for the drying box body 1 to dry the plastic particles in the storage barrel 13.
[0023] The lower inner wall of the drying box body 1 is fixedly connected to two support platforms 22 used in conjunction with the material storage barrel 13, and the outer surface of the material storage barrel 13 is rotatably connected to the inner walls of the two support platforms 22, and the support platforms 22 serve to facilitate supporting the material storage barrel 13.

The perspective glass 4 is convenient for observing the rotating position of the material pipe 11. When discharging is required, the material storage barrel 13 can be stopped by passing through the perspective glass 4 to rotate the material pipe 11 to a position convenient for discharging.
[0025] Working principle: First, open the box cover 6, at which time the material pipe 11 on the storage barrel 13 is in an upward position, then open the pipe cover 12, add the plastic particles to be dried into the storage barrel 13 through the material pipe 11, and then cover the pipe cover 12 and the box cover 6 in turn;

[0027] Then open the control valve 7 to drain the water from the drying box body 1 through the drain pipe 8;
[0028] Then, the drying element provided inside the drying box body 1 is started to dry the plastic particles. At the same time, the second motor 31 is started through the stirring mechanism 3. The output end of the second motor 31 drives one of the pulleys 33 to rotate. The rotation of one of the pulleys 33 cooperates with the conveyor belt 36 to make the other pulley 33 rotate as well. The rotation of the two pulleys 33 drives the two long rods 34 to rotate at the same time. The rotation of the two long rods 34 drives the stirring member 35 to rotate to continuously stir the plastic particles in the storage barrel 13, so that the plastic particles are dried more evenly.
[0029] After the plastic particles are dried, the material pipe 11 on the storage barrel 13 is rotated to a suitable discharge position through the drain mechanism 2. At this time, when the material pipe 11 rotates to the lower position, it can be observed through the transparent glass 4;
[0030] Then, the baffle 10 and the pipe cover 12 are opened, and the dried plastic particles are discharged through the material pipe 11 in cooperation with the material outlet 9. At the same time, the shaker 14 is started to shake the storage barrel 13 so as to better discharge the dried plastic particles.
[0031] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
