Description

Technical Field

[0001] The utility model relates to the technical field of plastic product production, in particular to a plastic rod rapid drying device. Background Art

[0002] Plastic rods are rods made of plastic material. The plastic raw materials are extruded through an extruder to form continuous strip rods, which are then cooled and cut into plastic rods of the same specifications. Plastic rods are usually cooled with water, and more moisture will remain on the surface, so they need to be dried before the next step.

[0003] Traditional drying equipment is a drying box or a drying tunnel. Plastic rods are directly placed in the drying box or the drying tunnel and dried by hot air. Although the surface of the plastic rods can be dried quickly, the position of the plastic rods in the drying box or the drying tunnel is relatively fixed, and the drying surface is fixed, which can easily lead to local surface overheating, causing internal stress changes and bending, affecting the uniformity and work efficiency of drying. Further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

The electric heating wire 10 is started synchronously for heating, and the hot air is used for drying. The driving motor 15 drives the mounting roller 7 to rotate, and then drives the plastic rod to revolve along the mounting roller 7. While the plastic rod revolves, it contacts the friction pad 8 of the side roller 5. The friction pad 8 drives the plastic rod to rotate through friction, changes the drying surface of the plastic rod, thereby improving the drying uniformity of the plastic rod and improving the drying efficiency.

[0030] In one embodiment, a plurality of rod grooves 3 are distributed at equal angles along the central axis of the mounting roller 7, and the mounting roller 7 is coaxially arranged with the drying chamber 1, so that the distance between the plastic rod and the heating wire 10 is the same, further improving the uniformity of drying.

[0031] In one embodiment, a plurality of balls 4 are densely and evenly arranged, and the radius of the balls 4 is smaller than the depth of the ball groove to prevent the balls 4 from falling. A ball groove is opened on the inner wall of the rod groove 3, and the balls 4 are rollingly connected inside the ball groove. The plastic rod and the balls 4 are rollingly abutted.
