Description
Technical Field
[0001] The utility model relates to the technical field of sorting devices, in particular to a sorting device for plastic processing raw materials. Background Art
[0002] The sorting device is used to sort plastic particles of different colors and separate them. The sorting device consists of a support table, a conveyor belt, a feed hopper, a collection box, a set of mounting plates, a baffle, and a sorting mechanism. When using the sorting device to separate black plastic particles from white plastic particles, the plastic particles are poured into the feed hopper. Due to their own weight, the plastic particles fall onto the conveyor belt. The conveyor belt starts, causing the plastic particles to slide from the end of the conveyor belt. Under the action of the baffle on the first mounting plate, they fall onto the sorting mechanism on the second mounting plate. The plastic particles are captured by a high-resolution camera in the sorting mechanism to obtain the image information of the plastic particles, and then transmitted to the image processing unit. Then, the image processing unit analyzes and processes the information and transmits it to the control system, thereby starting a high-speed jet of air to blow the white plastic particles to one side and the black plastic particles to the other side. Then, these plastic particles fall into both sides of the collection box.

[0029] Specifically, the specific settings and functions of the anti-blocking component 2 and the conveying component 3 will be described below.
[0030] Refer to Figure 3 and Figure 4 As shown in the figure, in this embodiment: The anti-blocking component 2 includes an impeller 21 rotatably connected to the inner wall of the feed hopper 10. A first motor 22 is installed on one side of the feed hopper 10. The output end of the first motor 22 is fixed to the impeller 21. By setting the anti-blocking component, when it is necessary to prevent plastic particles from accumulating and blocking in the feed hopper 10, the first motor 22 is started, so that the impeller 21 rotates. The impeller 21 rotates to rotate the plastic particles inside the feed hopper 10 out, thereby achieving the effect of preventing plastic particles from accumulating and blocking in the feed hopper 10. Two inclined plates 23 are fixedly connected to both sides of the inner wall of the feed hopper 10. A pushing mechanism 24 is arranged at the upper end of the inclined plate 23. A weighing plate 25 is installed on the surface of the impeller 21. A weighing sensor is installed inside the weighing plate 25. When it is necessary to discharge plastic particles with a fixed weight, under the action of an encoder, the first motor 22 makes the impeller 21 rotate to below the inclined plate 23, and then the plastic particles slide onto the weighing plate 25 on the impeller 21. After the weighing sensor in the weighing plate 25 detects the weight, the first motor 22 is started, so that the impeller 21 rotates the plastic out, and at the same time, the pushing mechanism 24 prevents plastic particles from accumulating on the inclined plate 23 and causing blockage. The pushing mechanism 24 includes a push plate 241 arranged at the upper end of the inclined plate 23. The push plate 241 slides on the upper end of the inclined plate 23. The push plate 241 is pushed to push the plastic particles on the inclined plate 23. Two electric telescopic rods 242 are installed on both sides of the inner wall of the feed hopper 10. The output end of the telescopic electric telescopic rod 242 is fixed to the push plate 241. The electric telescopic rod 242 is started to push the push plate 241.
[0031] Refer to Figure 2As shown in the figure, in this implementation: The conveying component 3 includes a conveying cylinder 32 fixedly connected between the collection box 6 and the feed hopper 10. The conveying cylinder 32 is used to transfer the plastic pellets on the inner wall of the collection box 6 to the feed hopper 10. When it is necessary to transfer the black plastic pellets in the collection box 6 to the feed hopper 10 for secondary sorting, through the driving mechanism, the black plastic pellets in the collection box 6 are conveyed to the feed hopper 10 through the conveying cylinder 32, so as to perform secondary sorting. A first auger 31 is provided on the inner wall of the collection box 6, and a second motor is installed on one side of the collection box 6. The first auger 31 is fixed to the output end of the second motor. When the second motor is started, the first auger 31 rotates to transfer the black plastic pellets to one side of the collection box 6. A second auger 33 is provided on the inner wall of the conveying cylinder 32. The inner wall of the collection box 6 is set as an arc surface. When the second auger 33 rotates, the black plastic pellets on one side of the collection box 6 are lifted and thus fall into the feed hopper 10. A third motor 34 is installed on the other side of the conveying cylinder 32, and the output end of the third motor 34 is fixed to the second auger 33. When the third motor 34 is started, the second auger 33 rotates.
[0032] Working principle:
[0033] When using a sorting device to separate black plastic particles from white plastic pellets, the plastic pellets are poured into the feed hopper 10. Due to their own weight, the plastic pellets fall onto the conveyor belt 9. The conveyor belt 9 starts, causing the plastic pellets to slide off the end of the conveyor belt 9. Under the action of the baffle 8 on the first mounting plate 7, they fall onto the sorting mechanism 5 on the second mounting plate 4. The plastic pellets are captured by a high-resolution camera in the sorting mechanism 5 to obtain the plastic pellet image information, which is then transmitted to the image processing unit. Then, the image processing unit analyzes and processes the information and transmits it to the control system, thereby activating the high-speed jet airflow to blow the white plastic pellets to one side and the black plastic pellets to the other side. Then, these plastic pellets fall into both sides of the collection box 6. When it is necessary to prevent plastic pellets from accumulating and blocking in the feed hopper 10, the first motor 22 is started, causing the impeller 21 to rotate. The impeller 21 rotates to transfer the plastic pellets inside the feed hopper 10, thereby achieving the effect of preventing plastic pellets from accumulating and blocking in the feed hopper 10. When it is necessary to discharge the plastic pellets with a fixed weight, under the action of the encoder, the first motor 22 causes the impeller 21 to rotate below the inclined plate 23. Then, the plastic pellets slide onto the weighing plate 25 on the impeller 21. When the weighing sensor in the weighing plate 25 detects (the weighing sensor is a product sold in the existing market, and how to weigh is prior art and will not be elaborated here) and reaches the required weight, the first motor 22 is started, causing the impeller 21 to transfer the plastic pellets out. At the same time, the pushing mechanism 24 is activated to prevent plastic pellets from accumulating and blocking on the inclined plate 23. The electric telescopic rod 242 is started to cause the pushing plate 241 to push, and the pushing plate 241 pushes to transfer the plastic pellets on the inclined plate 23. When it is necessary to transfer the black plastic pellets in the collection box 6 to the feed hopper 10 for secondary sorting, the second motor is started, causing the auger 31 to rotate to transfer the black plastic pellets to one side of the collection box 6. The third motor 34 is started, causing the auger 33 in the conveying cylinder 32 to rotate. The auger 33 rotates to lift the black plastic pellets on one side of the collection box 6, causing them to fall into the feed hopper 10 for secondary sorting.
