DETAILED DESCRIPTION
[0022] Clearly and completely describe the technical scheme in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model, obviously, the described embodiments are only a part of the embodiments of the utility model, and not all the embodiments.
[0023] Referring to Figs. 1 to 3 A waste plastic sorting and color separating device, comprising:
[0024] The plastic color sorter body 1 is fixedly connected to the feeding end of the plastic color sorter body 1 through the feeding channel; the top of the incomplete cylindrical feeding hopper 2 is provided with a sealing cover 11 which is rotatably installed, and the top of the sealing cover 11 is fixedly installed with a door-shaped handle 12; the sealing cover 11 can be closed when the device is not used, preventing foreign matters such as dust from entering the inside of the device, and ensuring that the color separation precision of the plastic color sorter body 1 is not affected, and the door-shaped handle 12 facilitates the operator to open the sealing cover 11 for feeding or cleaning work.
[0025] The intermittent feeding assembly comprises a crankshaft 4 rotatably installed in the incomplete cylindrical feeding hopper 2, and a driving motor 5 fixedly installed on the outer side of the incomplete cylindrical feeding hopper 2 and used for driving the self-rotation of the crankshaft 4; a plurality of stirring rods 10 are fixedly installed on the straight surface of the crankshaft 4; the length of each stirring rod 10 is less than the axial distance between the crankshaft 4 and the fixed shaft 7, so that the stirring rod 10 does not collide with the inner wall of the incomplete cylindrical feeding hopper 2 and the fixed shaft 7 during rotation, and the stability and safety of the device are ensured.
[0026] The curved section of the crankshaft 4 is movably sleeved with a swing plate 6; the surface of the swing plate 6 is provided with a sliding hole 13 which is in sliding connection with the crankshaft 4, so that the swing plate 6 can be stably driven to swing when the crankshaft 4 rotates.
[0027] The surface of the swing plate 6 is movably penetrated by a fixed shaft 7 which is fixedly installed in the incomplete cylindrical feeding hopper 2; the bottom of the swing plate 6 is fixedly installed with an arc-shaped material blocking plate 8 which is in sliding fit with the inner wall of the incomplete cylindrical feeding hopper 2; and two discharge ports 9 are symmetrically formed in the middle of the arc-shaped material blocking plate 8.
[0028] The working principle of the utility model is as follows:
[0029] In use, the waste plastics to be sorted and separated are first poured into the incomplete cylindrical feeding hopper 2, then the external power supply of the device is connected, and the driving motor 5 is started to drive the crankshaft 4 to start rotating; the curved section of the crankshaft 4 is in sliding fit with the swing plate 6 through the sliding hole 13 during rotation, and the fixed shaft 7 acts as a fulcrum for the swing plate 6, so that the swing plate 6 swings back and forth around the fixed shaft 7;
[0030] With the swing of the swing plate 6, the arc-shaped material blocking plate 8 at the bottom also swings in an arc-shaped manner. When the part of the arc-shaped material blocking plate 8 above the non-discharge port 9 swings to the position of the material inlet channel 3 at the bottom of the incomplete cylinder-shaped feeding hopper 2, the material blocking plate 8 will block the material and prevent the material from continuously falling; when the two discharge ports 9 on the arc-shaped material blocking plate 8 swing to be aligned with the material inlet channel 3, the waste plastic material in the incomplete cylinder-shaped feeding hopper 2 will fall into the material inlet channel 3 through the discharge ports 9 intermittently, and then enter the plastic color sorter body 1.
[0031] During the process, the plurality of stirring rods 10 on the straight surface of the crankshaft 4 rotate with the crankshaft 4, which plays a stirring role on the material in the incomplete cylinder-shaped feeding hopper 2, avoids the phenomenon of material blockage due to accumulation, and ensures that the material can uniformly and smoothly pass through the discharge port 9 to enter the subsequent processing link, realizes the intermittent quantitative feeding of the waste plastic material, and effectively improves the accuracy and efficiency of the plastic color sorter body 1 in material color separation and sorting.
[0032] Further, the above-mentioned fixed connection should be understood in a broad sense unless otherwise specified and limited, for example, it can be welding, or gluing, or integrally formed with other conventional means familiar to those skilled in the art.
