[0035] The vibration assembly 6 includes an inner filter plate 61 and an outer filter plate 62, the inner filter plate 61 is arranged at the bottom of the inner cavity of the centrifugal bin 2, and the outer filter plate 62 separates the space between the outer periphery of the centrifugal bin 2 and the inner wall of the collection bin 1, so that the space above the outer filter plate 62 forms a qualified product storage chamber 7, and the space at the bottom of the inner filter plate 61 and the outer filter plate 62 forms a broken product storage chamber 8, the filter hole diameters of the inner filter plate 61 and the outer filter plate 62 are the same and smaller than the diameter of the qualified plastic particles;

[0036] The stirring member 5 rotates to stir the plastic particles in the inner cavity of the centrifugal bin 2, at the same time, the driving source 3 drives the centrifugal bin 2 to rotate, and the centrifugal force generated by the centrifugal bin 2 makes the qualified plastic particles and part of the broken plastic particles enter the qualified product storage chamber 7 through the holes 4, at the same time, the stirring member 5 rotates to drive the inner filter plate 61 and the outer filter plate 62 to vibrate at the same time, so that the remaining broken plastic particles in the centrifugal bin 2 enter the broken product storage chamber 8 through the inner filter plate 61, and the broken plastic particles in the qualified product storage chamber 7 enter the broken product storage chamber 8 through the outer filter plate 62.

[0037] The stirring piece 5 in the inner cavity of the centrifugal bin 2 rotates by the self-provided driving device to stir the plastic particles in the inner cavity of the centrifugal bin 2, simultaneously drives the vibration assembly 6 to operate and the inner filter plate 61 to vibrate, thereby driving the plastic particles in the inner cavity of the centrifugal bin 2 to vibrate upward;

[0038] While the stirring piece 5 operates, the driving source 3 drives the centrifugal bin 2 to rotate in the inner cavity of the collecting bin 1. At this time, the centrifugal bin 2 generates a centrifugal force, the plastic particles move to the inner wall of the centrifugal bin 2 by the centrifugal force generated by the centrifugal bin 2, and the qualified product plastic particles and part of the broken plastic particles enter the qualified product storage chamber 7 by the setting that the qualified product plastic particles can pass through the hole 4 and the hole 4 is provided on the inner wall of the centrifugal bin 2. The outer filter screen and the inner filter screen are vibrated simultaneously, the outer filter screen is vibrated, and the broken plastic particles in the qualified product storage chamber 7 are screened into the broken product storage chamber 8 by the setting that the filter hole diameter of the outer filter plate 62 is smaller than the diameter of the qualified product plastic particles. The broken plastic particles in the centrifugal bin 2 are screened into the broken product storage chamber 8 by the vibration of the inner filter plate 61 and the setting that the filter hole diameter of the inner filter plate 61 is smaller than the diameter of the qualified product plastic particles, so that only the plastic particles in the form of adhesion due to incomplete cutting are left in the inner cavity of the centrifugal bin 2;

[0039] The centrifugal bin 2 rotates to generate a centrifugal force in the inner cavity of the centrifugal bin 2, thereby reducing the water droplets on the surface of the plastic particles. The qualified product particles and the broken plastic particles in the inner cavity of the centrifugal bin 2 enter the qualified product storage chamber 7 by the setting that the qualified product plastic particles can pass through the hole 4. The broken plastic particles in the qualified product storage chamber 7 are screened into the broken product storage chamber 8 by the vibration of the outer filter screen and the setting that the filter hole diameter of the outer filter plate 62 is smaller than the diameter of the qualified product plastic particles. The broken plastic particles in the inner cavity of the centrifugal bin 2 are screened into the broken product storage chamber 8 by the vibration of the inner filter plate 61 and the setting that the filter hole diameter of the inner filter plate 61 is smaller than the diameter of the qualified product plastic particles, so that the broken plastic particles in the inner cavity of the centrifugal bin 2 are screened into the broken product storage chamber 8. The device classifies the impurities while removing the impurities from the plastic particles, thereby solving the problem that the conventional screening device is difficult to screen the two kinds of impurities with different sizes and mutually adhered by water droplets.

[0040] Further, refer to Figure 4 and Figure 5For the above stirring piece 5, the stirring piece 5 comprises a central rod 51, a plurality of stirring blades 52 fixedly arranged on the outer periphery of the central rod 51, the side of the stirring blade 52 away from the central rod 51 is attached to the inner wall of the centrifugal bin 2, the bottom of the bifurcated support plate 53 is fixedly installed at the bottom of the centrifugal bin 2, the first motor 54 is fixedly installed at the bottom of the bifurcated support plate 53, and the output shaft end of the first motor 54 is fixedly connected with the bottom of the central rod 51.

[0041] The bottom of the centrifugal bin 2 is provided in an open shape, the first motor 54 drives the central rod 51 to rotate, thereby driving the stirring blade 52 to rotate, and further agitating the plastic particles in the inner cavity of the centrifugal bin 2, and at the same time, the side of the stirring blade 52 away from the central rod 51 is attached to the inner wall of the centrifugal bin 2, so that the side edge of the stirring blade 52 can scrape and clean the inner wall of the centrifugal bin 2, thereby avoiding the problem of the incomplete cutting and mutual adhesion of the plastic particles adhering to the inner wall of the centrifugal bin 2 due to the centrifugal force, causing the hole 4 to be blocked.

[0042] Further, referring to Figure 5 and Figure 6 For the above vibration assembly 6, the vibration assembly 6 further comprises a plurality of return springs 63, a vertical rod 64 is fixedly arranged at the top edge of the bifurcated support plate 53, the vertical rod 64 penetrates through the inner filter plate 61, the return spring 63 is arranged between the inner filter plate 61 and the bifurcated support plate 53 and is sleeved on the outer periphery of the vertical rod 64, a plurality of arc blocks 65 are fixedly arranged at the top edge of the inner filter plate 61, and the bottom of the stirring blade 52 is provided in an arc surface, so that when the bottom of the stirring blade 52 contacts the arc block 65, the inner filter plate 61 is driven to move downward.

[0043] When the stirring blade 52 rotates, the arc surface at the bottom of the stirring blade 52 contacts the arc surface on the upper surface of the arc block 65 and moves to the top of the arc block 65 in the process, the stirring blade 52 extrudes the arc block 65, so that the inner filter plate 61 moves downward, thereby compressing the return spring 63, when the stirring blade 52 continues to rotate and moves to the next arc block 65, the arc surface at the bottom of the stirring blade 52 contacts the side arc surface of the arc block 65, and the return spring 63 is gradually reset, thereby pushing the inner filter plate 61 upward, when the bottom of the stirring blade 52 contacts the top surface of the inner filter plate 61, the inner filter plate 61 is reset, and the arrangement of the plurality of arc blocks 65 enables the stirring blade 52 to contact the arc block 65 intermittently when rotating, thereby enabling the inner filter plate 61 to move downward intermittently, and the arrangement of the return spring 63 enables the inner filter plate 61 to move upward intermittently, thereby enabling the inner filter plate 61 to vibrate.

[0044] Further, referring to Figure 4 - Figure 6For the outer filter plate 62, the outer filter plate 62 is sleeved on the outer periphery of the centrifugal chamber 2, the outer periphery of the centrifugal chamber 2 is provided with a plurality of sliding grooves 66, the connecting plate 67 is fixedly arranged between the outer filter plate 62 and the inner filter plate 61, the connecting plate 67 is slidingly arranged in the inner cavity of the sliding groove 66, the elastic cloth 68 is fixedly arranged on the top and the bottom of the connecting plate 67, and the elastic cloth 68 is fixedly connected with the inner wall of the sliding groove 66 around;

[0045] Through the arrangement of the connecting plate 67, the outer filter plate 62 can be vibrated synchronously when the inner filter plate 61 is reciprocatingly vibrated during the rotation of the stirring blade 52, and the broken plastic particles in the inner cavity of the centrifugal chamber 2 and the inner cavity of the qualified product storage chamber 7 are screened. At the same time, through the arrangement of the elastic cloth 68, the sliding groove 66 is sealed, so that the plastic particles cannot move back and forth between the centrifugal chamber 2 and the qualified product storage chamber 7 through the sliding groove 66, and the problem of incomplete screening of the plastic particles is avoided.

[0046] Further, referring to Figure 7 For the stirring blade 52, the elastic assembly 9 is arranged on both sides of the stirring blade 52, the elastic assembly 9 comprises the movable plate 91, the hinge seat 92 matched with each other is fixedly installed on one side of the movable plate 91, the hinge seat 92 is installed on one side of the middle of the stirring blade 52, and the torsional spring 93 is installed at the hinge of the hinge seat 92, so that the movable plate 91 is in an inclined state in the original state.

[0047] When the torsional spring 93 is in a natural stretching state, the movable plate 91 is in an inclined state, and the lower side of the movable plate 91 is away from the stirring blade 52 and the upper side is close to the stirring blade 52. When the stirring blade 52 rotates, the bottom of the movable plate 91 is in contact with the arc-shaped block 65. The arrangement of the arc-shaped block 65 enables the bottom of the movable plate 91 to rotate to one side of the stirring blade 52, so as to press the torsional spring 93 and make it elastically deform. When the stirring blade 52 continuously rotates and extrudes the arc-shaped block 65 and moves the inner filter plate 61 downward, the bottom of the movable plate 91 is separated from the arc-shaped block 65. At this time, the torsional spring 93 resets and drives the bottom of the movable plate 91 to rotate away from the stirring blade 52. Through the elastic force generated by the torsional spring 93, a certain impact force is generated when the movable plate 91 resets. The impact force generated by the reciprocating rotation of the movable plate 91 cooperates with the plastic particles on the inner filter plate 61 to reciprocatingly vibrate, so that the plastic particles can continuously collide in the space formed by the surface of the inner filter plate 61, the side wall of the centrifugal chamber 2 and the corresponding movable plate 91 of the adjacent two stirring blades 52, so as to separate the plastic particles adhered by the water, facilitate the impurity removal of the plastic particles, and shake off part of the water on the surface of the plastic particles.

[0048] Further, referring to Figure 7For the above stirring blade 52, a rectangular hole 94 is formed in the stirring blade 52, a support plate is fixedly installed in the rectangular hole 94, and hinge seats 92 are respectively installed on both sides of the support plate. The side orthogonal projection of the movable plate 91 fills in the rectangular hole 94, and when the movable plate 91 is in an inclined state, the top of the movable plate 91 is located in the rectangular hole 94, so that during the process that the bottom of the movable plate 91 contacts and separates from the arc-shaped block 65, the top of the movable plate 91 gradually rotates and moves away from the rectangular hole 94, and after the bottom of the movable plate 91 separates from the arc-shaped block 65, the movable plate 91 is reset by the torsional spring 93.

[0049] The rectangular hole 94 is arranged, so that there is no obstacle in the space formed between the movable plate 91 and the stirring blade 52, thereby reducing the filling of plastic particles between the movable plate 91 and the stirring blade 52, and the situation that the movable plate 91 cannot rotate is avoided, and the operation of the elastic assembly 9 is ensured.

[0050] Further, referring to Figure 6 For the above centrifugal bin 2, a waterproof cover 10 is installed at the bottom center of the bifurcated support plate 53, the first motor 54 is arranged in the inner cavity of the waterproof cover 10, the driving source 3 includes a second motor 31, the waterproof cover 10 is fixedly installed with a rotating rod 11 at the bottom, the bottom end of the rotating rod 11 extends to the bottom of the collection bin 1 and is rotatably connected with the collection bin 1 through a bearing, and the output shaft end of the second motor 31 is fixedly connected with one end of the rotating rod 11.

[0051] The waterproof cover 10 is arranged to form waterproof protection for the first motor 54, and the rotation of the centrifugal bin 2 is driven by the second motor 31, so that the centrifugal bin 2 generates centrifugal force.

[0052] Further, referring to Figure 1 For the above centrifugal bin 2 and collection bin 1, a feeding pipe 12 is installed at the top shaft center of the centrifugal bin 2 and is rotatably connected with the centrifugal bin 2 through a bearing, and a hatch cover 14 is arranged at the top of the centrifugal bin 2. The collection bin 1 is provided with bin doors 13 at the top and bottom of the outer periphery.

[0053] Through the arrangement that the feeding pipe 12 is rotatably connected with the centrifugal bin 2, the transportation of the plastic particles into the inner cavity of the centrifugal bin 2 through the feeding pipe 12 is not affected during the rotation of the centrifugal bin 2, and the qualified plastic particles, broken plastic particles and bonded plastic particles are collected through the arrangement of the bin doors 13 and the hatch cover 14.

[0054] Working principle: in use, the driving source 3 and the first motor 54 operate simultaneously, the driving source 3 drives the centrifugal bin 2 to rotate, so that the centrifugal force is generated in the inner cavity of the centrifugal bin 2, and the first motor 54 drives the stirring part 5 to rotate, so as to stir the inner cavity of the centrifugal bin 2.

[0055] The stirring piece 5 operates to drive the stirring blade 52 to rotate around the central rod 51. When the stirring blade 52 rotates, the arc surface at the bottom of the stirring blade 52 contacts the arc surface on the upper surface of the arc block 65 and moves to the top of the arc block 65 in the process. The stirring blade 52 extrudes the arc block 65, so that the inner filter plate 61 moves downward, thereby extruding the return spring 63. When the stirring blade 52 continues to rotate and moves to the next arc block 65, the arc surface at the bottom of the stirring blade 52 contacts the side arc surface of the arc block 65, and the return spring 63 gradually recovers elasticity, thereby pushing the inner filter plate 61 upward. When the bottom of the stirring blade 52 contacts the top surface of the inner filter screen, the inner filter plate 61 is reset. The plurality of arc blocks 65 are arranged to be contacted by the stirring blade 52 in an interval when the stirring blade 52 rotates, so that the inner filter plate 61 moves downward in an interval, and the inner filter plate 61 moves upward in an interval through the arrangement of the return spring 63, thereby making the inner filter plate 61 vibrate, so that the plastic particles in the inner cavity of the centrifugal bin 2 are vibrated upward by the inner filter plate 61, avoiding the accumulation of plastic particles on the inner filter plate 61. While the stirring piece 5 stirs the plastic particles, the driving source 3 drives the centrifugal bin 2 to rotate in the inner cavity of the collection bin 1. When the centrifugal bin 2 rotates, a centrifugal force is generated in the inner cavity of the centrifugal bin 2. When the stirring piece 5 rotates, the plastic particles contact the stirring piece 5. The centrifugal force generated by the centrifugal bin 2 makes the plastic particles in the inner cavity of the centrifugal bin 2 move to the inner wall of the centrifugal bin 2. Through the arrangement of the hole 4 provided on the inner wall of the centrifugal bin 2 and the qualified plastic particles capable of passing through the hole 4, the qualified plastic particles and part of the broken plastic particles enter the qualified product storage chamber 7. Through the arrangement that the outer filter screen and the inner filter screen vibrate at the same time, the outer filter screen vibrates, and the broken plastic particles in the qualified product storage chamber 7 are screened to the broken product storage chamber 8 through the arrangement that the filter hole diameter of the outer filter plate 62 is smaller than the diameter of the qualified plastic particles;

[0056] At the same time, through the vibration of the inner filter plate 61 and the arrangement that the filter hole diameter of the inner filter plate 61 is smaller than the diameter of the qualified plastic particles, the broken plastic particles among the remaining plastic particles in the inner cavity of the centrifugal bin 2 are screened into the broken product storage chamber 8, so that only the plastic particles in the form of adhesion due to incomplete cutting caused by incomplete cooling are left in the inner cavity of the centrifugal bin 2;

[0057] When the stirring blade 52 rotates, the bottom of the movable plate 91 is in contact with the arc-shaped block 65, and the arc-shaped block 65 is arranged such that the bottom end of the movable plate 91 rotates to one side of the stirring blade 52, thereby pressing and elastically deforming the torsion spring 93. When the stirring blade 52 continuously rotates and presses the arc-shaped block 65 and moves the inner filter plate 61 downward, the arc-shaped block 65 moves downward, and the bottom of the movable plate 91 is separated from the arc-shaped block 65. At this time, the torsion spring 93 resets and drives the bottom of the movable plate 91 to rotate away from the stirring blade 52. The impact force generated when the movable plate 91 resets is generated by the elastic force of the torsion spring 93. The impact force generated by the reciprocating rotation of the movable plate 91 cooperates with the plastic particles on the inner filter plate 61 to reciprocate and vibrate, so that the plastic particles can continuously collide in the space formed by the surface of the inner filter plate 61, the side wall of the centrifugal bin 2 and the corresponding movable plate 91 of the two adjacent stirring blades 52, so that the plastic particles bonded by water are separated, the plastic particles are easily removed, and part of the water on the surface of the plastic particles is shaken off.

[0058] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
