[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-6 The end of the outer ring surface of the mounting tube 1 close to the feeding hopper 4 is rotatably provided with a mounting frame 11, and the end of the outer ring surface of the mounting tube 1 away from the mounting frame 11 is provided with a ball head rod 12, the upper end of the ball head rod 12 is a ball head end and is clamped with a ball head seat 13, and the end of the ball head seat 13 away from the ball head rod 12 is connected with a telescopic cylinder 14. The setting of the telescopic cylinder 14 is convenient for adjusting the inclination angle of the mounting tube 1, thereby adjusting the residence time of the plastic bottle pieces in the mounting tube 1, and then controlling the drying degree of the plastic bottle pieces in this scheme; the rotation drive component includes a motor 15 and a reducer 16 The motor 15 is installed at the end of the mounting tube 1 close to the discharge pipe 5. The two ends of the reducer 16 are respectively connected to the rotating shaft 2 and the output end of the motor 15. The setting of the rotation drive component is convenient for driving the rotating shaft 2 to rotate with little effort, and reduces the speed of the rotating shaft 2; a filter plate 17 is provided at one end of the sealing cover 6 close to the fan 7, and the filter plate 17 is connected to the sealing cover 6 by screws. The setting of the filter plate 17 is convenient for filtering the air entering the sealing cover 6, thereby avoiding contamination of the cleaned plastic bottle pieces.

[0027] A mounting groove is provided on one side of the sealing cover 6, and an observation plate 18 is installed in the mounting groove. The setting of the observation plate 18 is convenient for personnel to observe the operating status of the internal heating wire 8 without disassembling the sealing cover 6, so as to timely maintain and replace it; a guide cover 19 is provided on the inner wall of the sealing cover 6, and the small end of the guide cover 19 points to the air cavity 9 of the rotating shaft 2. The setting of the guide cover 19 facilitates the hot air to enter the air cavity 9; the diameter of the air outlet 10 is smaller than the size of the plastic bottle piece, and the air outlet direction of the air outlet 10 is consistent with the rotation direction of the rotating shaft 2. Since the diameter of the air outlet 10 is smaller than the size of the plastic bottle piece, the plastic bottle piece can be prevented from blocking the air outlet 10.

[0028] Principle and advantages of use: During the use of the utility model, the cleaned plastic bottle chips from the outside are fed into the feeding hopper 4, and then fall into the inside of the mounting tube 1. At this time, the motor 15 drives the rotating shaft 2 to rotate through the reducer 16, and when the rotating shaft 2 rotates, the plastic bottle chips inside the mounting tube 1 are turned over by turning the protrusion 3. In this process, the outside air is injected into the sealing cover 6 through the fan 7, and enters the air outlet 10 from the inside of the sealing cover 6 along the air cavity 9. At this time, the air ejected from the air outlet 10 can dry the plastic bottle chips that are constantly rolling inside the mounting tube 1.

[0029] Furthermore, in the above process, since the sealing cover 6 is provided with a heating wire 8, the room temperature air blown into the sealing cover 6 by the fan 7 is heated by the heating wire 8, and then the heated hot air can be blown onto the surface of the plastic bottle flakes to dry them more thoroughly and quickly, thereby improving the efficiency of drying the plastic bottle flakes; in summary, during the use of this scheme, the plastic bottle flakes can be rolled by moving the setting of the protrusion 3, so as to facilitate sufficient air drying of each surface of the plastic bottle flakes, and at the same time, the inclined mounting tube 1 can also make the plastic bottle flakes automatically move to the lower material pipe 5, so as to facilitate discharge, and further, the setting of the heating wire 8 can heat the air entering the sealing cover 6, so that under the action of the hot air, the plastic bottle flakes can be dried faster, thereby improving the processing efficiency of the plastic bottle flakes.

[0030] It should be further explained that the provision of the telescopic cylinder 14 facilitates the adjustment of the inclination angle of the mounting tube 1, thereby adjusting the residence time of the plastic bottle flakes inside the mounting tube 1, and further controlling the degree of drying of the plastic bottle flakes by this scheme; the provision of the rotating drive assembly facilitates the effortless driving of the rotating shaft 2 to rotate, and reduces the rotation speed of the rotating shaft 2; the provision of the filter plate 17 facilitates the filtering of the air entering the sealing cover 6, thereby avoiding the contamination of the cleaned plastic bottle flakes; the provision of the observation plate 18 facilitates personnel to observe the operating status of the internal heating wire 8 of the sealing cover 6 without disassembling it, thereby timely maintaining and replacing it; the provision of the guide cover 19 facilitates the entry of hot air into the air cavity 9; since the diameter of the air outlet 10 is smaller than the size of the plastic bottle flakes, the plastic bottle flakes can be prevented from clogging the air outlet 10.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
