Detailed implementation manners

[0027] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0028] Embodiment:

[0029] As Figures 1-4 shown, the present invention provides a technical solution for a plastic particle screening device:

[0030] As shown in the figure, a plastic particle screening device, its structure includes a base 1, a screening frame 2 provided on the upper surface of the base 1, a connecting spring 3 for connecting the screening frame 2 and the base 1, a hopper 4 provided on the upper surface of the screening frame 2, a discharge hopper 5 located at the front part of the lower surface of the screening frame 2, and a stroking structure 6 located on the upper surface of the screening frame 2. The stroking structure 6 includes mounting sleeve frames 61 located on both sides of the upper surface of the screening frame 2, telescopic cylinders 62 provided on the upper surfaces of the mounting sleeve frames 61, connecting rods 63 on the upper side surfaces of the upper parts of the telescopic cylinders 62, a connecting rod 64 connected to the two connecting rods 63, a cooperating movable frame 65 provided on the lower surface of the connecting rod 64, two movable rods 66 with their ends extending into the interior of the cooperating movable frame 65, and roller shaft members 67 provided at the other ends of the movable rods 66.

[0031] A sieve plate 21, cold air ducts 22 located on both sides of the sieve plate 21, and track frames 23 provided on the left and right sides inside the screening frame 2 are arranged inside the screening frame 2.

[0032] The track frames 23 are matched with the roller shaft members 67.

[0033] A cold air blower is arranged inside the base 1 and is matched with the cold air ducts 22 to further enhance the cooling treatment of the plastic particles.

[0034] The telescopic cylinder 62 is electrically connected to the base 1.

[0035] The roller shaft member 67 includes a fitting frame 671 connected to the other end of the movable rod 66, cleaning shafts 672 symmetrically arranged on the left and right sides of the fitting frame 671, and push plates 673 provided on the front and rear surfaces of the fitting frame 671 and connected thereto, which is beneficial for pushing the plastic particles back and forth to prevent them from adhering to the surface of the sieve plate, thereby achieving effective screening treatment. And in cooperation with the rolling of the cleaning shafts, the holes on the surface of the sieve plate can be cleaned.

[0036] The cleaning shafts 672 are in sliding fit with both the fitting frame 671 and the track frame 23 to achieve reciprocating pushing on the upper surface of the sieve plate, preventing the plastic particles from sticking together due to heat or adhering to the surface of the sieve plate, which is not conducive to the screening treatment.

[0037] The two movable rods 66 are connected by a movable hinge rod.

[0038] The telescopic cylinder 62 is electrically connected to the base 1, and in cooperation with the connecting rod, it drives the movable rod and the roller shaft member as a whole to reciprocate on the upper surface of the screening frame, thereby realizing the pushing, vibrating and cleaning of the plastic particles on the upper surface of the screening frame.

[0039] The push plate 673 is detachably and movably installed on the fitting frame 671, which is convenient for disassembling and replacing the push plate.

[0040] The specific implementation principle is as follows: The plastic particles to be screened are poured through the hopper 4 and enter the inside of the screening frame 2. When the equipment is started, the screening frame 2 vibrates under the action of the connecting spring 3. Since the telescopic cylinder 62 is electrically connected to the base 1, it moves up and down telescopically after being electrified, thereby driving the connecting rod 63 and the connecting rod 64 connected thereto, so that the movable rod 66 connected to the movable frame 65 moves up and down, driving the roller shaft member 67 connected to the end of the movable rod 66 to reciprocate on the upper surface of the sieve plate 21. And the cold air pipe 22 is connected to the cold air blower arranged inside the base 1 to realize synchronous cooling of the plastic particles to prevent the plastic particles from sticking due to their high own temperature, resulting in ineffective screening treatment.

[0041] The cooperatively arranged push plate 673 pushes the plastic particles on the upper surface of the sieve plate 21 back and forth, and at the same time uses the cleaning shafts 672 to clear the foreign matters flowing through the holes on the surface of the sieve plate 21.

[0042] The foregoing has shown and described the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced by the present invention. Any reference signs in the claims should not be construed as limiting the claims involved.

This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
