[0014] The present invention provides a recycled plastic dewatering device having the following beneficial effects:

[0015] (1) In the recycled plastic dewatering device, the plastic particles in the feed hopper move to the inside of the drying cylinder through the gap between the sealing plate and the fixed frame, and the sealing plate controls the intermittent discharge of the feed hopper through the intermittent contact between the arc surface 1 and the arc sheet, ensuring that the plastic particles discharged each time can be fully dried.

The corrugated surface 1 is in close contact with the trapezoidal plate, providing additional support for the sealing plate, which helps to reduce the wear and fatigue of the sealing plate, thereby extending the service life.

[0016] (2) In the recycled plastic dehydration device, the plastic particles hinder the roller, and the roller moves toward the rectangular plate due to the resistance. The movement of the roller improves the fluidity of the plastic particles in the area close to the heating layer, promotes heat transfer, and accelerates the evaporation of water or solvent, thereby shortening the drying time. The rotating plate rotates upward at an acute angle to reduce the resistance encountered by the cross plate when it moves downward. The cross plate moves back and forth up and down to continuously turn over the plastic particles at the bottom, ensuring that each plastic particle is fully dried in the drying cylinder, thereby improving the overall heating efficiency.

[0017] (3) In the recycled plastic dewatering device, the comb plate transmits vibration to the sealing plate, causing the sealing plate to shake the plastic particles below. The knocking plate intermittently collides with the comb plate, so that the sealing plate is shaken multiple times when moving downward, effectively reducing the possibility of the sealing plate getting stuck when moving, thereby improving the working stability. The downward reset of the convex rod is limited by the elastic sheet, and the downward reset of the sealing plate is restricted. The position of the elastic sheet can be changed through standardized operations, which makes it convenient for operators to choose to use intermittent feeding or one-time feeding according to different situations, effectively improving the convenience of feeding.

[0030] An arc surface 1 is provided on the top of the mounting plate 10, and a scroll spring No. 1 is arranged between the rotating plate 14 and the cross plate 13. The rotating plate 14 rotates to stretch the scroll spring No. 1, and the plastic particles at the bottom of the drying cylinder 2 are continuously turned over through the cross plate 13, ensuring that each plastic particle is fully dried in the drying cylinder 2, thereby improving the overall heating efficiency.

[0031] The second arc surface is provided at one end of the abutment plate 15 close to the rotating plate 14, and the second arc surface contacts the bottom of the rotating plate 14. By providing the second arc surface on the abutment plate 15, the wear generated when the rotating plate 14 contacts the abutment plate 15 is reduced, and at the same time, it is ensured that the abutment plate 15 limits the rotating plate 14 from rotating downward.

[0032] When the present embodiment is working, hot air is transported to the heating layer 4 through the air inlet pipe of the docking mechanism 5, the plastic particles are poured from the feed hopper into the drying cylinder 2, the driving motor 6 is started, and the output end of the driving motor 6 drives the stirring rod 7 to rotate counterclockwise, the stirring rod 7 rotates and drives the rectangular plate 9 to move toward the docking mechanism 5, the rectangular plate 9 moves and drives the carrying plate 10 to move toward the docking mechanism 5, the carrying plate 10 moves and drives the roller 12 to move toward the docking mechanism 5, the No. 1 spring sheet 11 in deformation exerts a reaction force on the carrying plate 10 under the action of its own elasticity, the carrying plate 10 exerts a thrust on the roller 12 under the influence of the reaction force, the roller 12 is in close contact with the inner wall of the drying cylinder 2 under the action of the thrust, so that the roller 12 moves and contacts the drying cylinder 2 Friction is generated between the rollers 12, and the roller 12 rotates under the influence of the friction force. At the same time, the movement of the roller 12 drives the plastic particles close to the heating layer 4 to move. When the roller 12 encounters firmly adhered plastic particles during its movement, the plastic particles impose an obstacle on the circumferential surface of the roller 12, and the roller 12 is affected by the resistance and moves toward the rectangular plate 9. The roller 12 moves and separates from the inner wall of the drying cylinder 2. At the same time, the movement of the roller 12 drives the carrying plate 10 to move toward the rectangular plate 9. The carrying plate 10 squeezes the No. 1 spring piece 11 during the movement, so that the No. 1 spring piece 11 is squeezed and deformed. When the roller 12 is separated from the firmly adhered plastic particles, the No. 1 spring piece 11 recovers under the action of its own elasticity, and the recovery of the No. 1 spring piece 11 drives the carrying plate 10 to reset, and the carrying plate 10 is mounted on the roller 12. The movement of the carrier plate 10 drives the roller 12 to reset. When the roller 12 moves, it contacts the inner wall of the drying cylinder 2. The movement of the roller 12 improves the fluidity of the plastic particles in the area close to the heating layer 4, promotes heat transfer, and accelerates the evaporation of water or solvent, thereby shortening the drying time. The rotation of the stirring rod 7 drives the reciprocating screw rod 8 to rotate counterclockwise. The reciprocating screw rod 8 rotates to drive the cross plate 13 to reciprocate up and down. When the cross plate 13 moves downward, the cross plate 13 drives the rotating plate 14 to move downward. The plastic particles accumulated at the bottom exert resistance on the bottom of the rotating plate 14. The rotating plate 14 is affected by the resistance and rotates in the direction away from the abutment plate 15. The rotating plate 14 is separated from the arc surface 2 during the rotation. At the same time, the rotating plate 14 rotates to stretch the No. 1 scroll spring. The scroll spring is stretched and deformed, and the rotating plate 14 rotates upward to form an acute downward angle on the cross plate 13, thereby reducing the resistance encountered by the cross plate 13 when it moves downward. When the cross plate 13 moves upward, the cross plate 13 drives the rotating plate 14 to move upward, and the resistance encountered by the bottom of the cross plate 13 gradually decreases. The deformed scroll spring No. 1 recovers and drives the rotating plate 14 to rotate to the initial position. The rotating plate 14 contacts the second arc surface during rotation, and the rotation of the rotating plate 14 toward the abutment plate 15 is restricted, so that the movement of the rotating plate 14 drives the plastic particles at the bottom to move upward, and the plastic particles at the bottom are constantly turned over by the up and down reciprocating movement of the cross plate 13, ensuring that each plastic particle is fully dried in the drying cylinder 2, thereby improving the overall heating efficiency.

[0033] See also Figure 1-Figure 9 On the basis of the above embodiment, another embodiment of the present invention further includes a feed conveying device and a locking device; the feed conveying device includes a fixed frame 161, a convex rod 162, and a No. 1 spring 163.

The trapezoidal plate 167 is fixedly installed on the bottom of the inner wall of the fixed frame 161. The rubber block 168 slides through the side of the sealing plate 166 close to the trapezoidal plate 167. The second spring piece 169 is arranged between the rubber block 168 and the sealing plate 166. A trapezoidal groove is provided at the bottom of the sealing plate 166. The bottom of the sealing plate 166 contacts the bottom of the inner wall of the fixed frame 161, and intermittently contacts the arc surface 1 with the arc-shaped piece 164, so that the sealing plate 166 controls the intermittent discharge of the feed hopper to ensure that the plastic particles discharged each time can be fully dried.

[0034] A slope 1 is provided on one side of the trapezoidal plate 167 close to the trapezoidal groove, and an arc surface 3 is provided at the bottom of the rubber block 168. By providing the slope 1 and the arc surface 3, it is ensured that the resistance applied by the trapezoidal plate 167 can smoothly affect the movement of the rubber block 168.

[0035] A corrugation 1 is provided on one side of the rubber block 168 close to the trapezoidal plate 167 , and the corrugation 1 is in contact with the trapezoidal plate 167 . The corrugation 1 fits tightly with the trapezoidal plate 167 , thereby providing additional support for the sealing plate 166 , helping to reduce wear and fatigue of the sealing plate 166 , thereby extending its service life.

[0036] The locking device includes a carrying frame 171, a comb plate 172, a knocking piece 173, a pushing block 174, a pull rod 175, a second spring 176, a cylindrical rod 177, a clamping plate 178 and an elastic sheet 179. The carrying frame 171 is fixedly mounted on a side of the feed hopper close to the round rod 165, the comb plate 172 is fixedly penetrated on a side of the carrying frame 171 close to the round rod 165, the knocking piece 173 is rotatably mounted on a side of the comb plate 172 close to the carrying frame 171, the pushing block 174 slides through the inner and outer walls of the carrying frame 171, the pull rod 175 slides through the side of the pushing block 174 away from the carrying frame 171, and the second spring 176 is arranged between the pull rod 175 and the pushing block 174, the cylindrical rod 177 is fixedly mounted on the circumferential surface of the pull rod 175, the clamping plate 178 is fixedly mounted on the side of the mounting frame 171 away from the feed hopper, the elastic sheet 179 is fixedly mounted on the side of the pushing block 174 close to the comb plate 172, and the end of the comb plate 172 close to the knocking plate 173 is provided with an arc surface four, and the arc surface four contacts the top of the knocking plate 173, and the knocking plate 173 itself is elastic. A No. 2 spiral spring is arranged between the knocking plate 173 and the comb plate 172, and the intermittent collision between the knocking plate 173 and the comb plate 172 is realized, so that the blocking plate 166 is shaken multiple times when it moves downward, which effectively reduces the jamming of the blocking plate 166 when it moves.

[0037] A card slot is provided on one side of the card plate 178 close to the cylindrical rod 177, and the cylindrical rod 177 contacts the inner wall of the card slot. The position of the elastic sheet 179 can be changed by standardized operation, so that the operator can choose to use intermittent feeding or one-time feeding according to different situations, thereby effectively improving the convenience of feeding.

[0038] When the present embodiment is working, the outlet of the feed hopper near the drying cylinder 2 is blocked by the blocking plate 166, so that the plastic particles stay in the feed hopper. The arc surface 1 of the carrying plate 10 contacts the bottom of the arc piece 164 during the movement. The movement of the arc surface 1 applies an upward thrust to the arc piece 164. The arc piece 164 moves upward under the influence of the thrust. The movement of the arc piece 164 drives the convex rod 162 to move upward. The convex rod 162 stretches the No. 1 spring 163 when moving. The No. 1 spring 163 is stretched and deformed. At the same time, the movement of the convex rod 162 drives the round rod 165 and the blocking plate 166 to move upward. The blocking plate 166 and the arc piece 164 move upward. The bottom of the inner wall of the fixed frame 161 is separated, and the blockage of the plugging plate 166 on the outlet of the feed hopper is released. The plastic particles inside the feed hopper move to the inside of the drying cylinder 2 through the gap between the plugging plate 166 and the fixed frame 161. The arc surface 1 continues to move and separates from the arc piece 164. The thrust on the bottom of the arc piece 164 gradually decreases, and the deformed spring 163 recovers and drives the convex rod 162 to move downward. The movement of the convex rod 162 drives the round rod 165 and the plugging plate 166 to move downward. The plugging plate 166 contacts the bottom of the inner wall of the fixed frame 161 during movement, so that the outlet of the feed hopper is blocked by the plugging plate 166. The arc-shaped piece 164 is in intermittent contact, so that the blocking plate 166 controls the intermittent discharge of the feed hopper to ensure that the plastic particles discharged each time can be fully dried. The blocking plate 166 moves upward and drives the rubber block 168 to move. The corrugation 1 of the rubber block 168 generates friction with the trapezoidal plate 167 during the movement. The corrugation 1 continues to move and separates from the contact surface of the trapezoidal plate 167. The deformed second spring piece 169 recovers and drives the rubber block 168 to move away from the blocking plate 166. The blocking plate 166 moves downward and drives the rubber block 168 to move. The arc surface 3 of the rubber block 168 contacts the inclined surface 1 during the movement. The inclined surface contacts the arc surface 3. When resistance is applied, the rubber block 168 is affected by the resistance and moves toward the blocking plate 166. The rubber block 168 squeezes the second spring sheet 169 during the movement, and the second spring sheet 169 is squeezed and deformed. The deformed second spring sheet 169 applies a reaction force to the rubber block 168 under the action of its own elasticity. The corrugation 1 of the rubber block 168 is affected by the reaction force and is in close contact with the trapezoidal plate 167, so that the rubber block 168 provides additional support for the blocking plate 166. The corrugation 1 is closely fitted with the trapezoidal plate 167, providing additional support for the blocking plate 166, which helps to reduce the wear and fatigue of the blocking plate 166, thereby extending the service life.

[0039] When the round rod 165 moves upward, the round rod 165 contacts the bottom of the knocking piece 173. Since the arc surface four blocks the upward rotation of the knocking piece 173, the round rod 165 continues to move to squeeze the knocking piece 173. The knocking piece 173 is squeezed and deformed. When the contact surface of the round rod 165 and the knocking piece 173 is separated, the knocking piece 173 recovers under the action of its own elasticity. When the round rod 165 moves downward, the round rod 165 contacts the top of the knocking piece 173. The round rod 165 moves and applies downward pressure on the knocking piece 173. The knocking piece 173 rotates downward under the influence of the pressure. The knocking piece 173 is separated from the arc surface four during the rotation process. At the same time, the knocking piece 173 rotates to stretch the No. 2 scroll spring. The No. 2 scroll spring is stretched and deformed. The second scroll spring is deformed, and the deformed second scroll spring stores energy under the action of its own elasticity. When the round rod 165 and the knocking plate 173 are separated, the pressure on the round rod 165 is gradually reduced, and the deformed second scroll spring is restored to provide kinetic energy for the knocking plate 173, so that the knocking plate 173 rotates upward quickly. During the rotation, the knocking plate 173 collides with the arc surface 4 to generate vibration, and the comb plate 172 transmits the vibration to the blocking plate 166, so that the blocking plate 166 shakes the plastic particles below when it moves downward. Through the intermittent collision between the knocking plate 173 and the comb plate 172, the blocking plate 166 is shaken multiple times when it moves downward, which effectively reduces the jamming of the blocking plate 166 when it moves. When the operator needs to continue discharging, he manually pulls the pull rod 175 The pull rod 175 moves in the direction away from the pushing block 174, and the pull rod 175 stretches the No. 2 spring 176 during the movement. The No. 2 spring 176 is deformed by the stretching, and at the same time, the pull rod 175 moves to drive the cylindrical rod 177 to move in the direction away from the card plate 178. The surface of the cylindrical rod 177 in contact with the card slot is separated during the movement, so that the limit imposed by the card plate 178 on the pushing block 174 is released, and the pull rod 175 is pushed to move in the direction of the comb plate 172. The movement of the pull rod 175 drives the cylindrical rod 177 to move in the direction of the comb plate 172. At the same time, the movement of the pull rod 175 drives the pushing block 174 to move in the direction of the comb plate 172. The movement of the pushing block 174 drives the elastic sheet 179 to move in the direction of the comb plate 172. After the elastic sheet 179 moves to the predetermined position, the pull rod 175 is released. Rod 175, the deformed No. 2 spring 176 recovers and drives the pull rod 175 to move in the direction of the push block 174. The movement of the pull rod 175 drives the cylindrical rod 177 to move in the direction of the clamping plate 178. The cylindrical rod 177 contacts the inner wall of the clamping slot during the movement, so that the clamping plate 178 imposes a limit on the movement of the push block 174. When the round rod 165 moves upward, it contacts the bottom of the elastic sheet 179. Since the arc surface exerts an upward thrust on the arc-shaped sheet 164, the round rod 165 moves to squeeze the elastic sheet 179. The elastic sheet 179 is squeezed and deformed. The round rod 165 continues to move and separates from the surface in contact with the elastic sheet 179. The elastic sheet 179 recovers under the action of its own elasticity. When the round rod 165 moves downward, it contacts the top of the elastic sheet 179.Since the pulling force applied by the No. 1 spring 163 to the convex rod 162 when it is restored is smaller than the elastic coefficient of the elastic sheet 179 itself, the convex rod 162 is limited by the elastic sheet 179 when it is reset downward, and the blocking plate 166 is limited when it is reset downward, so that the plastic particles in the feed hopper are quickly moved to the inside of the drying cylinder 2. By changing the position of the elastic sheet 179 through standardized operation, it is convenient for operators to choose to use intermittent feeding or one-time feeding according to different situations, which effectively improves the convenience of feeding.
