[0002] Plastic granules refer to granular plastics. In the production process of polypropylene plastic granules, the polypropylene plastic granules generally need to be dried by a drying device to facilitate the collection and subsequent processing of the polypropylene plastic granules.

[0003] In the prior art, some plastic particle drying devices pour the plastic from top to bottom onto a plurality of staggered inclined plates in the device, and dry the plastic particles as the plastic particles slide downward along the inclined plates. However, since the plastic particles slide downward along the inclined plates all the time, their residence time in the device is usually fixed, which greatly limits the drying effect of the plastic particles, especially some plastic particles with high humidity cannot be fully dried. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] See also Figure 1-3 A plastic granule drying device comprises a support base 1, a box body 2 mounted on the support base 1 and a drying module 3 mounted in the box body 2, wherein a feed port 4 and a discharge port 5 are respectively arranged on the top surface and the bottom of the side surface of the box body 2, and a plurality of inclined inclined plates 6 are arranged from top to bottom in the box body 2, and the adjacent inclined plates 6 are inclined in opposite directions, and a guide plate 7 is further arranged below the inclined plate 6 in the box body 2, and the center position of the guide plate 7 is rotatably arranged through a support shaft 8, and an electric push rod 9 is symmetrically arranged between the bottom surface of the guide plate 7 and the bottom surface of the box body 2, and a cylinder 10 is further installed on the side of the box body 2 away from the discharge port 5, and a feed pipe and a discharge pipe connected to the box body 2 are respectively arranged on the top and bottom of the side surface of the cylinder body 10, and a feeding dragon is installed in the cylinder body 10 11. By setting the guide plate 7, the support shaft 8, the electric push rod 9, the cylinder 10 and the feeding dragon 11, the plastic particles enter the box body 2 through the feed port 4 and slide downward along the multiple inclined plates 6. The staff can control the extension and contraction of the two electric push rods 9 according to the humidity of the plastic particles. When the two electric push rods 9 control the guide plate 7 to tilt toward the cylinder 10, the plastic particles can enter the cylinder 10 and flow back to the uppermost inclined plate 6 under the action of the feeding dragon 11, thereby realizing the secondary or multiple drying of the plastic particles, so that the device can adapt to the drying of plastic particles with different humidity, thereby improving the practicability of the device. On the contrary, when the guide plate 7 tilts toward the discharge port 5, the dried plastic particles can be discharged from the box body 2.

[0020] Among them, the inclined lower end position of the inclined plate 6 is rotatably set by the installation shaft 12, and a driving component for driving multiple inclined plates 6 to flip back and forth is also provided in the box body 2. The driving component includes a sleeve 13 symmetrically fixedly installed on the top surface of the inner cavity of the box body 2, a movable rod 14 symmetrically movably arranged in the box body 2, a plurality of push-pull rods 16 hingedly installed on the movable rod 14, and a power unit for driving the movable rod 14 to move up and down. One end of the movable rod 14 is movably inserted in the sleeve 13, and a spring 15 is arranged between the end and the sleeve 13, and the other end of the movable rod 14 passes through the bottom surface of the box body 2. The push-pull rod 16 is hinged to the inclined high end face of the inclined plate 6. The installation shaft 12 and the driving component are set. In the process of plastic particles sliding downward along the inclined plate 6, the driving component can drive multiple inclined plates 6 to flip back and forth at high speed, so that the plastic particles are constantly flipped on the inclined plate 6, avoiding the plastic particles from being compacted on the inclined plate 6 and being retained, thereby improving the drying effect of the plastic particles to a certain extent.

[0021] In addition, in order to prevent the movable rod 14 from hindering the extension of the discharge pipe into the box body 2, two movable rods 14 are provided on one side in the present application, and connecting plates 17 are installed at the ends of the two movable rods 14 that pass through the bottom surface of the box body 2.

[0022] Specifically, the power unit includes a drive shaft 18 rotatably disposed in the support seat 1 and a pair of cams 19 symmetrically mounted on the drive shaft 18 . The drive shaft 18 is driven by a motor disposed on the side of the support seat 1 . The rotation trajectory of the cam 19 interferes with the movement trajectory of the connecting plate 17 .

[0023] Furthermore, a roller 20 is installed on the bottom surface of the connecting plate 17. The setting of the roller 20 reduces the friction resistance between the connecting plate 17 and the cam 19, so that the movable rod 14 moves up and down more smoothly.

[0024] Furthermore, the drive shaft 18 is connected to the feeding dragon 11 through the bevel gear set 21. With this arrangement, there is no need to set up an additional driving element to drive the rotation of the feeding dragon 11, which saves electric energy and reduces drying costs.

[0025] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.

[0026] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
