[0030] The embodiment of the present application provides a plastic product drying device, which refers to Figure 1 The plastic product drying device comprises a feeding conveyor belt 1, a hot air machine 2, a receiving plate 3 and a discharging conveyor belt 4, wherein the feeding conveyor belt 1 can convey the particles to be dried onto the receiving plate 3, then the hot air machine 2 blows hot air on the surface of the particles on the receiving plate 3 for drying, the dried particles fall onto the discharging conveyor belt 4, and finally the discharging conveyor belt 4 conveys the dried particles to a specified station.

[0031] Specifically, the receiving plate 3 is horizontally placed, and the bottom can be fixed to the ground or a station through supporting legs. The hot air machine 2 is correspondingly fixed above the receiving plate 3, and the air outlet of the hot air machine 2 is vertically downward, and the hot air machine 2 itself can generate hot air and blow out from the air outlet.

[0032] The feeding conveyor belt 1 is also horizontally placed, and the discharging end of the feeding conveyor belt 1 is located between the receiving plate 3 and the air outlet of the hot air machine 2, and the feeding conveyor belt 1 is placed higher than the receiving plate 3. A discharging opening 31 is formed in the middle part of the receiving plate 3, the discharging opening 31 corresponds to the air outlet of the hot air machine 2, and the discharging end of the feeding conveyor belt 1 corresponds to the position of the discharging opening 31. A transition plate 11 is fixed below the discharging end of the feeding conveyor belt 1, the transition plate 11 is inclined downward, the upper end of the transition plate 11 receives the discharging end of the feeding conveyor belt 1, and the lower end of the transition plate 11 corresponds to the position of the discharging opening 31, so that the particles to be dried can slide to the discharging opening 31 through the transition plate 11 after falling from the feeding conveyor belt 1.

[0033] In order to receive the particles to be dried, a horizontal discharging plate 32 is arranged at the discharging opening 31, so that the particles can be supported by the discharging plate 32 and not fall off, and the particles can stay on the discharging plate 32 for drying.

[0034] With reference to Figure 1 And Figure 2 In order to avoid accumulation of excessive particles, the receiving plate 3 is further provided with a turning block 5 at the discharging opening 31. Specifically, the turning block 5 is horizontally and reciprocally connected to the top of the discharging plate 32 and in contact with the top surface of the discharging plate 32. The turning block 5 includes a middle part 51 and two turning shovel parts 52. Along the moving direction of the turning block 5, the two turning shovel parts 52 are respectively fixed to the two sides of the middle part 51. In the embodiment of the present application, the middle part 51 and the turning shovel parts 52 are integrally formed.

[0035] Along the moving path of the turning block 5 and away from the middle part 51, the distance between the top surface of the turning shovel part 52 and the top surface of the discharging plate 32 gradually decreases and finally closely adheres to the top surface of the discharging plate 32, and the top surface of the turning shovel part 52 is always smoothly transitioned.

[0036] In order to facilitate turning of the particles, the top surface of the turning shovel part 52 is inclined or arc-shaped. In the embodiment of the present application, the top surface of the turning shovel part 52 is arc-shaped with a large radius of curvature, and the thickness of the end of the turning shovel part 52 is small, so that the end of the turning shovel part 52 can more easily shovel into the particles below, thereby turning the particles. The top surface of the middle part 51 is arc-shaped, and when the particles are shoveled to the top surface of the turning shovel part 52 and rolled from the top surface of the middle part 51 to the top surface of the turning shovel part 52 on the other side, the middle part 51 with the arc-shaped top surface can avoid having particles staying above the middle part 51.

[0037] The width of the turning block 5 is less than the width of the discharging opening 31, so that the turning block 5 has enough space to reciprocally move in the discharging opening 31, so as to sufficiently turn the particles.

[0038] With reference to Figure 2 And Figure 3In order to drive the moving of the turnover block 5, a driving rod 53 is horizontally slidably connected in the receiving plate 3, and the driving rod 53 is limited to horizontally move in the receiving plate 3. One end of the driving rod 53 is fixedly connected with the side wall of the middle part 51, and the other end is fixedly connected with a horizontal first rack 531. The receiving plate 3 is fixedly connected with a first driving member 33 corresponding to the bottom surface of the first rack 531. The first driving member 33 can be a small servo motor. A first gear 34 is coaxially fixed on the output shaft of the first driving member 33. An opening is formed on the receiving plate 3 corresponding to the position of the first gear 34. The first gear 34 extends out of the opening and is engaged with the first rack 531. The output shaft of the first driving member 33 drives the first gear 34 to rotate. The rotating first gear 34 drives the engaged first rack 531 to move in the horizontal direction. The first rack 531 drives the turnover block 5 to reciprocate through the driving rod 53. The output shaft of the first driving member 33 is reversed to realize the reciprocating movement of the turnover block 5 at the material falling port 31.

[0039] With reference to Figure 1 and Figure 4 , in order to enable the dried material particles to fall onto the discharging conveying belt 4, a sliding groove 35 for the horizontal sliding of the discharging plate 32 is formed in the receiving plate 3 corresponding to the position of the discharging plate 32. When the discharging plate 32 moves in the sliding groove 35, the discharging plate 32 can open or close the material falling port 31.

[0040] The discharging plate 32 is fixedly connected with a second rack 36 at one end in the receiving plate 3. The receiving plate 3 is fixedly connected with a second driving member 37 corresponding to the bottom surface of the second rack 36. Similarly, the second driving member 37 can also be a small servo motor. A second gear 38 is coaxially fixed on the output shaft of the second driving member 37. An opening is formed on the receiving plate 3 corresponding to the position of the second gear 38. The second gear 38 extends out of the opening and is engaged with the second rack 36. The second driving member 37 drives the receiving plate 3 to reciprocate through the second gear 38 and the second rack 36. The driving mode of the turnover block 5 is similar, and will not be described again.

[0041] Further, with reference to Figure 1 , the bottom surface of the receiving plate 3 is fixedly connected with a material falling funnel 39 corresponding to the material falling port 31. The material falling funnel 39 is communicated with the material falling port 31. The inner diameter of the material falling funnel 39 gradually decreases from top to bottom. The bottom end of the material falling funnel 39 is close to the surface of the discharging conveying belt 4. When the material particles are completely dried, the discharging plate 32 is opened. The material particles fall into the material falling funnel 39 from the material falling port 31 by relying on their own gravity, and finally fall stably on the discharging conveying belt 4 through the material falling funnel 39, avoiding the scattering of the material particles. The dried material particles are conveyed to the target position by the discharging conveying belt 4.

[0042] The implementation principle of the plastic product drying device is as follows: the blanking plate 32 is extended from the receiving plate 3 under the driving of the second gear 38 and the second rack 36, and the blanking port 31 can be closed, at this time, the granules can fall on the blanking plate 32 and stay, then the air heater 2 is started to blow hot air on the granules on the blanking plate 32 to dry, at the same time of blowing hot air, the turning block 5 is driven by the first gear 34, the first rack 531 and the driving rod 53 to reciprocate on the surface of the blanking plate 32, in the reciprocating process of the turning block 5, the end of the turning shovel part 52 shovels up the granules, with the continuous movement of the turning shovel part 52, the granules are shovelled up and turned over by the turning shovel part 52, part of the pushed granules can also turn over the middle part 51, and roll from the turning shovel part 52 on one side to the turning shovel part 52 on the other side, so that the granules are fully turned over, and each surface of the granules can be dried under the hot air.
