[0002] Polycarbonate is a high molecular polymer containing carbonate groups in the molecular chain. According to the structure of the ester group, it can be divided into many types such as aliphatic, aromatic, aliphatic-aromatic, etc. Among them, due to the low mechanical properties of aliphatic and aliphatic-aromatic polycarbonates, their application in engineering plastics is limited. Only aromatic polycarbonate has achieved industrial production. Due to the special structure of polycarbonate, it has become the fastest-growing general engineering plastic among the five major engineering plastics.

[0013] In summary, the beneficial effects of the present utility model are as follows:

[0014] 1. This structure uses the dispersing mechanism to first disperse the large agglomerated polycarbonate particles, and then uses the flattening mechanism to evenly distribute the dispersed polycarbonate particles on the conveyor belt, which facilitates the subsequent uniform heating and drying of the polycarbonate particles by the heating mechanism and the drying mechanism. At the same time, since the heating mechanism is arranged in the heat insulation chamber, the polycarbonate particles do not contact the heat source during the processes of being dispersed and flattened, so the adhesion problem of the polycarbonate particles can be effectively avoided.

[0015] 2. The dispersing pieces can poke the large agglomerated polycarbonate particles to separate them from each other.

[0016] 3. The pressing plate is used to limit the stacking thickness of the polycarbonate particles on the conveyor belt, preventing the problem that the polycarbonate particles cannot be uniformly heated due to excessive stacking.

[0017] 4. The air outlet is used to cool the polycarbonate particles that have been heated, and at the same time helps to remove the residual moisture on the polycarbonate particles. Brief Description of the Drawings

[0026] Embodiment:

[0027] As Figures 1 to 5 shown, the present invention discloses a polycarbonate particle drying device, including a conveyor table 1, on which a conveyor belt 11 is arranged. At the same time, a dispersion mechanism, a flattening mechanism, a heat insulation chamber 41, and a drying mechanism are sequentially arranged above the conveyor belt 11 along the conveying direction of the conveyor belt 11 on the conveyor table 1. In addition, a heating mechanism is arranged in the heat insulation chamber 41.

[0028] Furthermore, the dispersing mechanism includes a first rotating shaft 22, a first motor 21, and several groups of dispersing blade groups 23 arranged on the first rotating shaft 22. In this structure, the first rotating shaft 22 is rotatably arranged on the conveying table 1, the first motor 21 is fixedly arranged on the conveying table 1 and its output end is connected to the first rotating shaft 22. At the same time, the setting scheme of each group of dispersing blades 231 is as follows: each dispersing blade group 23 includes several dispersing blades 231 fixedly arranged on the first rotating shaft 22. The connection point between each dispersing blade 231 and the first rotating shaft 22 is eccentrically arranged compared to the center of the dispersing blade 231. At the same time, the dispersing blades 231 within each group of dispersing blade groups 23 are arranged circumferentially around the axis of the first rotating shaft 22, and moreover, the dispersing blades 231 within each group of dispersing blade groups 23 are arranged at intervals along the axis direction of the first rotating shaft 22 on the first rotating shaft 22.

[0029] The flattening mechanism includes a second rotating shaft 32, a second motor 31, a cam 33, and a pressing plate 36. Among them, the second rotating shaft 32 is rotatably arranged on the conveying table 1, the second motor 31 is fixedly arranged on the conveying table 1 and its output end is connected to the second rotating shaft 32, and the cam 33 is fixedly arranged on the second rotating shaft 32. In this structure, the pressing plate 36 is slidably arranged up and down between the cam 33 and the conveyor belt 11, and the cam 33 and the pressing plate 36 are linked. The cam 33 can drive the pressing plate 36 to move up and down by rotation.

[0030] The linkage scheme between the cam 33 and the pressing plate 36 is as follows: a slide rail 331 is provided on the cam 33, and the track of the slide rail 331 is formed by equally reducing the contour of the cam 33. At the same time, a slider 341 is slidably arranged in the slide rail 331. In addition, a connecting rod 342 and a fixing plate 35 are arranged between the cam 33 and the pressing plate 36. In this structure, the upper end of the connecting rod 342 is fixedly connected to the slider 341 and its lower end is fixedly connected to the pressing plate 36, while the fixing plate 35 is fixedly arranged between the pressing plate 36 and the cam 33, and a limiting groove 351 for the connecting rod 342 to slide up and down is provided on the fixing plate 35.

[0031] The heating mechanism includes a heating tube 42 fixedly arranged in the heat insulation chamber 41.

[0032] The drying mechanism includes an air outlet chamber 51, and an air outlet 52 for discharging air from top to bottom is provided on the air outlet chamber 51.

[0033] The working principle of the above structure is as follows: When the polycarbonate particles move on the conveyor table 1, first, the first motor 21 drives the dispersing piece 231 on the first rotating shaft 22 to rotate, so that the dispersing piece 231 pokes open the agglomerated large polycarbonate particles. If you want to further improve the effect, multiple sets of dispersing mechanisms can be set on the conveyor table 1. Subsequently, the second motor 31 drives the cam 33 to rotate, so that the cam 33 drives the pressing plate 36 to move up and down. During the downward movement of the pressing plate 36, the stacking thickness of the polycarbonate particles can be limited to prevent the polycarbonate particles from stacking too thickly and being unable to be uniformly heated. Subsequently, the heating tube 42 in the heat insulation chamber 41 heats and dries the polycarbonate particles. When the polycarbonate particles leave the heat insulation chamber 41, air starts to flow out from the air outlet 52 of the air outlet chamber 51 to cool the polycarbonate particles and blow away the excess water vapor, so as to facilitate the subsequent collection of the polycarbonate particles.

[0034] At the same time, it should be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present invention.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
