A placement box is slidably arranged below the heater inside the drying box, and a control mechanism for driving the heater to move is arranged on the drying box; the control mechanism includes a frame fixed on the top of the drying box. This patent relates to the technical field of crystallization drying. In this particle crystallization drying device for recycled plastics, by arranging a control mechanism on the drying box to drive the heater to move, under the action of the control mechanism, the heater reciprocates above the placement box.

[0014] The present invention provides a drying device for waste plastic recycling. It has the following beneficial effects:

[0015] (1) The drying device for waste plastic recycling. The first elastic piece exerts a reaction force on the extrusion plate, making the extrusion plate in close contact with the docking plate. By providing a stable additional supporting force for the cylindrical rod, the stability of the stirring operation is effectively improved, thereby accelerating the drying process of the plastic and ensuring the high efficiency of the plastic drying operation. At the same time, the rotating roller drives the plastic close to the cylinder to move, and the turning effect of the material is improved by the rotation of the roller along the cylinder. This can not only ensure the uniformity of the drying process but also effectively prevent the phenomenon of plastic adhesion due to long-term heating.

[0016] (2) The drying device for waste plastic recycling. Under the action of the thrust, the contact plate is in close contact with the abutting plate. By the close contact between the contact plate and the abutting plate, additional friction is increased, thereby enhancing the stability of the connecting rod. This can prevent the cylinder from shaking violently due to the impact force of the plastic when the plastic is put in. At the same time, the connecting plate provides additional support for the support rod. Through the supporting force provided by the support rod, it is ensured that the abutting plate can smoothly come into stable contact with the contact plate on the other side, which helps to improve the stability of the cylinder during the stirring operation.

[0017] (3) The drying device for waste plastic recycling. During the movement, the Z-shaped plate exerts an additional thrust on the support rod. By the Z-shaped plate providing an additional thrust for the support rod to reset, it makes it easier and more labor-saving for the operator to open the cylinder, thereby improving the overall work efficiency. At the same time, the speed of the Z-shaped plate during reset is slowed down by the influence of friction. The rubber plate provides an effective decelerating effect at the initial stage of the Z-shaped plate reset, effectively preventing the impact caused by collision and avoiding vibration or unstable factors caused by too fast speed.

Detailed implementation manner

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1 - 7 , an embodiment of the present invention is: a drying device for waste plastic recycling, including a drying oven 1, a heating device 2 is arranged on the top of the drying oven 1, a drainage plate 3 is fixedly penetrated through the bottom of the inner wall of the drying oven 1, and a material turning device is further included; wherein, the material turning device includes a drive motor 5, a cylindrical rod 6, a stirring blade 7, a docking plate 8, a carrier frame 9, an air-permeable plate 10, a cylinder 11 and a connecting rod 12. When the air-permeable plate 10 is in use, its structural design allows air to flow freely, and at the same time has a liquid drainage function. The drive motor 5 is fixedly penetrated through the inner and outer walls of the drying oven 1, the cylindrical rod 6 is fixedly installed at the output end of the drive motor 5, the stirring blade 7 is fixedly installed on the circumferential surface of the cylindrical rod 6, the docking plate 8 is fixedly installed on the side of the cylindrical rod 6 away from the drive motor 5, the carrier frame 9 is fixedly installed inside the drying oven 1, the air-permeable plate 10 is fixedly installed on the inner wall of the carrier frame 9, the cylinder 11 slides through the side of the drying oven 1 away from the drive motor 5, the connecting rod 12 is fixedly installed on the circumferential surface of the cylinder 11, the cylindrical rod 6 rotates through the inner and outer walls of the carrier frame 9, a chute is provided on the carrier frame 9, and the connecting rod 12 contacts the inner wall of the chute. By installing the air-permeable plate 10, the air flow rate in the cylinder 11 is effectively increased, thus ensuring the smooth progress of the drying operation.

[0028] On one side of the drying oven 1 close to the cylinder 11, an electric latch 4 is fixedly installed. Inside the inner wall of the cylinder 11, a rotating plate 13 is rotatably installed. On one side of the rotating plate 13 close to the docking plate 8, a rotating roller 14 is rotatably installed. On one side of the rotating plate 13 close to the docking plate 8, a docking frame 15 is fixedly installed. Inside the inner wall of the docking frame 15, a pressing plate 16 slides through. Between the pressing plate 16 and the docking frame 15, a first elastic piece 17 is arranged. The rotating roller 14 contacts the inner wall of the cylinder 11. By rotating the rotating roller 14 along the cylinder 11, the effect of turning the materials is improved. This can not only ensure the uniformity of the drying process but also effectively prevent the phenomenon of plastics sticking due to long-term heating.

[0029] On one side of the docking plate 8 close to the docking frame 15, a first inclined surface is provided. On one side of the pressing plate 16 away from the rotating plate 13, a first arc surface is provided. On the circumferential surface of the cylinder 11, a limiting groove is provided. The size of the limiting groove is adapted to the output end of the electric latch 4. By providing a stable additional supporting force for the cylindrical rod 6, the stability of the stirring operation is effectively improved, thereby accelerating the drying process of the plastics and ensuring the high efficiency of the drying operation on the plastics.

[0030] When this embodiment is working, pour the recycled plastic waste into the cylinder 11, and then manually push the cylinder 11 towards the direction of the driving motor 5. The movement of the cylinder 11 drives the rotating plate 13 to move towards the direction of the driving motor 5. The movement of the rotating plate 13 drives the roller 14 and the docking frame 15 to move towards the direction of the driving motor 5. The movement of the docking frame 15 drives the pressing plate 16 to move towards the direction of the driving motor 5. The first arc surface of the pressing plate 16 contacts the first inclined surface of the docking plate 8 during the movement. The first inclined surface exerts a resistance on the first arc surface, causing the pressing plate 16 to move towards the direction of the first elastic piece 17. The pressing plate 16 moves to press the first elastic piece 17, and the deformed first elastic piece 17 exerts a reaction force on the pressing plate 16, making the pressing plate 16 in close contact with the docking plate 8. The docking frame 15 provides additional support for the cylindrical rod 6 through the docking plate 8. At the same time, the movement of the cylinder 11 drives the connecting rod 12 to move towards the direction of the driving motor 5. The connecting rod 12 stops moving after moving to the end point of the chute. At this time, the cylinder 11 stays at the designated position. Then start the electric lock 4. The output end of the electric lock 4 contacts the limit groove to apply a limit to the cylinder 11. Then start the heating device 2 to dry the waste in the cylinder 11. The wastewater inside the waste flows downward through the air-permeable plate 10 into the inside of the drainage plate 3, and the drainage plate 3 then discharges the sewage out of the drying box 1. At the same time, during the drying process, start the driving motor 5. The output end of the driving motor 5 drives the cylindrical rod 6 to rotate. The rotation of the cylindrical rod 6 drives the stirring blade 7 to rotate. The stirring blade 7 stirs the contacted waste during the rotation. By providing a stable additional supporting force for the cylindrical rod 6, the stability of the stirring operation is effectively improved, thereby accelerating the drying process of the plastic and ensuring the high efficiency of the plastic drying operation. While the cylindrical rod 6 rotates, it drives the docking plate 8 to rotate. The rotation of the docking plate 8 drives the docking frame 15 to rotate. The rotation of the docking frame 15 drives the rotating plate 13 to rotate. The rotation of the rotating plate 13 drives the roller 14 to rotate along the inner wall of the cylinder 11. The roller 14 contacts the plastic close to the cylinder 11 during the rotation, causing the roller 14 to drive the plastic close to the cylinder 11 to move. At the same time, the roller 14 generates friction with the inner wall of the cylinder 11 during the rotation, and the roller 14 rotates self-driven under the action of the frictional force. After the waste is dried, first turn off the heating device 2 and the driving motor 5, then start the electric lock 4 to release the limit applied to the cylinder 11, and finally the operator slowly opens the cylinder 11 to take out the waste. By the roller 14 rotating along the cylinder 11 to improve the effect of turning the material, it can not only ensure the uniformity of the drying process, but also effectively prevent the plastic from sticking due to long-term heating.

[0031] Please refer to Figures 1 - 7, on the basis of the above embodiments, in another embodiment of the present invention, a stabilizing device for improving the stability of the cylinder 11 is provided on the drying box 1, and a pushing device for facilitating discharging is provided on the stabilizing device; the stabilizing device includes a connecting plate 181, a sliding rod 182, a hollow rod 183, a support rod 184 and a resisting plate 185. The connecting plate 181 is fixedly penetrated through the inner and outer walls of the drying box 1. The sliding rod 182 is slidably installed on the inner wall of the connecting plate 181. The hollow rod 183 is fixedly installed on the side of the sliding rod 182 away from the connecting plate 181. The support rod 184 is fixedly installed on the circumferential surface of the sliding rod 182. The resisting plate 185 is fixedly installed on the circumferential surface of the sliding rod 182. The inner wall of the hollow rod 183 contacts the circumferential surface of the connecting rod 12. A through groove is formed on the connecting plate 181. The circumferential surface of the support rod 184 contacts the inner wall of the through groove. By tightly contacting the contact plate 188 with the resisting plate 185 to increase the friction force, it can effectively prevent the cylinder 11 from shaking violently due to the impact force of the plastic during the feeding of the plastic.

[0032] A plurality of T-shaped rods 186 are slidably penetrated through the surface of the connecting plate 181. A first spring 187 is arranged between the plurality of T-shaped rods 186 and the connecting plate 181. A contact plate 188 is fixedly installed on the side of the plurality of T-shaped rods 186 close to the sliding rod 182. The contact plate 188 contacts the outer side wall of the resisting plate 185. Through the supporting force provided by the support rod 184, it is ensured that the resisting plate 185 can smoothly and stably contact the contact plate 188 on the other side.

[0033] Arc surfaces two are formed on both sides of the resisting plate 185 away from the contact plate 188. Two inclined surfaces two are formed at the bottom of the contact plate 188. By forming the arc surfaces two and the inclined surfaces two, it is ensured that when the resisting plate 185 contacts the contact plate 188, the contact plate 188 can be smoothly pushed to move.

[0034] The pushing device includes a C-shaped plate 191, a fixing rod 192, a hollow cylinder 193, a second spring 194, a Z-shaped plate 195, a rubber plate 196 and a second elastic sheet 197. The C-shaped plate 191 is fixedly installed on the surface of the connecting plate 181. The fixing rod 192 is fixedly installed inside the C-shaped plate 191. The hollow cylinder 193 is slidably installed on the circumferential surface of the fixing rod 192. The second spring 194 is arranged between the hollow cylinder 193 and the C-shaped plate 191. The Z-shaped plate 195 is fixedly installed on the side of the hollow cylinder 193 away from the second spring 194. The rubber plate 196 is slidably penetrated through the inner and outer walls of the C-shaped plate 191. The second elastic sheet 197 is arranged between the rubber plate 196 and the C-shaped plate 191. By providing an additional thrust for the support rod 184 to reset through the Z-shaped plate 195, it makes it easier and more labor-saving for the operator to open the cylinder 11.

[0035] One side of the Z-shaped plate 195 close to the rubber plate 196 is provided with an inclined surface three, and one side of the rubber plate 196 away from the second elastic piece 194 is provided with a corrugated groove. The rubber plate 196 provides an effective deceleration effect at the initial stage of the reset of the Z-shaped plate 195, effectively preventing the impact caused by the collision and avoiding the vibration or instability factors caused by too fast speed.

[0036] When this embodiment works, when the plastic is poured into the inside of the cylinder 11, the cylinder 11 shakes due to the impact of the plastic. The shaking of the cylinder 11 drives the connecting rod 12 to move. The movement of the connecting rod 12 drives the hollow rod 183 to move. The movement of the hollow rod 183 drives the sliding rod 182 to move. The movement of the sliding rod 182 drives the abutting plate 185 to move. And the deformed first spring 187 exerts a reaction force on the T-shaped rod 186, so that the T-shaped rod 186 exerts a thrust on the contact plate 188. Under the action of the thrust, the contact plate 188 is in close contact with the abutting plate 185, resulting in friction between the abutting plate 185 and the contact plate 188 during movement. The additional frictional force improves the stability of the abutting plate 185, effectively controlling the shaking of the cylinder 11. By increasing the frictional force through the close contact between the contact plate 188 and the abutting plate 185, it can effectively prevent the cylinder 11 from shaking violently due to the impact force of the plastic when the plastic is put in. When the operator pushes the cylinder 11 to move, the connecting rod 12 moves to drive the hollow rod 183 to move in the direction of the drive motor 5. The movement of the hollow rod 183 drives the sliding rod 182 to move in the direction of the drive motor 5. The movement of the sliding rod 182 drives the support rod 184 and the abutting plate 185 to move in the direction of the drive motor 5. When the support rod 184 moves, the connecting plate 181 provides additional support for the support rod 184 through the through groove. And the abutting plate 185 separates from the contact plate 188 during movement, so that the deformed first spring 187 resumes its shape and drives the T-shaped rod 186 to move in the direction of the abutting plate 185. The movement of the T-shaped rod 186 drives the contact plate 188 to move in the direction of the abutting plate 185. The abutting plate 185 continues to move and contacts the contact plate 188 on the other side. When contacting, the arc surface two of the abutting plate 185 presses the inclined surface two of the contact plate 188, and the contact plate 188 is pushed to move away from the abutting plate 185. The movement of the contact plate 188 drives the T-shaped rod 186 to move away from the abutting plate 185. The T-shaped rod 186 stretches the first spring 187 during movement. The deformed first spring 187 exerts a reaction force on the T-shaped rod 186, so that the abutting plate 185 remains stable after moving to a predetermined position. Through the supporting force provided by the support rod 184, it is ensured that the abutting plate 185 can stably contact the contact plate 188 on the other side smoothly, which helps to improve the stability of the cylinder 11 during the stirring operation;

[0037] The circumferential surface of the support rod 184 contacts the side of the Z-shaped plate 195 away from the rubber plate 196 during movement, causing the movement of the support rod 184 to drive the Z-shaped plate 195 to move towards the rubber plate 196. The movement of the Z-shaped plate 195 drives the hollow cylinder 193 to move towards the rubber plate 196. The hollow cylinder 193 squeezes the second spring 194 during movement, and the second spring 194 deforms under the extrusion. When the hollow cylinder 193 moves to the specified position, the operator activates the electric lock 4 to limit the movement of the cylinder 11. After the drying operation is completed, the operator turns off the electric lock 4 to release the limit on the cylinder 11. Then, the restored deformed second spring 194 drives the hollow cylinder 193 to move away from the rubber plate 196. The movement of the hollow cylinder 193 drives the Z-shaped plate 195 to move away from the rubber plate 196. The Z-shaped plate 195 exerts an additional thrust on the support rod 184 during movement, making it easier for the operator to open the cylinder 11. By providing an additional thrust for the support rod 184 to reset through the Z-shaped plate 195, the operator can open the cylinder 11 more easily and labor-savingly, thereby improving the overall work efficiency. When the Z-shaped plate 195 moves towards the rubber plate 196, the inclined surface three of the Z-shaped plate 195 contacts the rubber plate 196. The inclined surface three continues to move and squeezes the rubber plate 196. The rubber plate 196 is squeezed and moves towards the second elastic piece 197. The rubber plate 196 moves and squeezes the second elastic piece 197, and the second elastic piece 197 deforms under the extrusion, making the corrugated groove of the rubber plate 196 in close contact with the Z-shaped plate 195. When the Z-shaped plate 195 resets, friction is generated with the corrugated groove. The speed of the Z-shaped plate 195 during reset is slowed down by the frictional force. When the Z-shaped plate 195 separates from the rubber plate 196, the restored deformed second elastic piece 197 drives the rubber plate 196 to reset. By providing an effective deceleration effect by the rubber plate 196 at the initial stage of the reset of the Z-shaped plate 195, the impact caused by the collision is effectively prevented, and the vibration or unstable factors caused by too high speed are avoided.
