[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 An embodiment of this utility model is provided: a dust cleaner for plastic granule production, including a plastic granule production equipment 1, a feeding channel 2 and a baffle 7. The feeding channel 2 is provided at the right end of the plastic granule production equipment 1, and a conductive block 6 is provided at the front end of the feeding channel 2. A vacuum cleaner 3 is connected to the upper side of the feeding channel 2. The conductive block 6 is connected to the front end of the feeding channel 2. A baffle 7 is provided at the right end of the feeding channel 2. A fixing block 10 is fixedly connected to the right side of the feeding channel 2. A limiting component is provided in the middle of the interior of the fixing block 10. A receiving box 18 is provided at the lower end of the feeding channel 2.

[0021] Furthermore, the upper end of the discharge channel 2 is provided with a through hole that connects to the suction port of the vacuum cleaner 3. The suction port of the vacuum cleaner 3 is connected to the interior of the discharge channel 2. A filter screen 4 is provided at the opening of the suction port of the vacuum cleaner 3. This structure can suck away the dust between the sliding plastic particles and reduce the dust between the plastic particles.

[0022] Furthermore, a baffle 5 is sleeved in the middle of the inner wall of the discharge channel 2 through a rotating shaft, and both the baffle 5 and the rotating shaft are made of iron. The upper end of the conductive block 6 is connected to the rotating shaft on the baffle 5 through a connecting wire. The bottom of the conductive block 6 is in contact with the ground, and the bottom of the baffle 5 is adapted to the inner wall of the discharge channel 2. This structure can cause the dust on the surface of the plastic particles to fall off by impacting the surface of the baffle 5. At the same time, when the plastic particles come into contact with the surface of the baffle 5, the static electricity that may be generated on the surface can be conducted through the baffle 5 and then discharged through the contact between the conductive block 6 and the ground.

[0023] Furthermore, the inner surface of the baffle 7 is provided with a rubber pad, and the upper end of the baffle 7 is connected to the feed channel 2 through a rotating shaft. The front end of the rotating shaft of the baffle 7 is fixedly connected to a rotating block 8. The surface of the rotating block 8 is provided with abutment blocks 9 at equal intervals in a ring, and the surface of the abutment blocks 9 is set in an inclined shape. This structure can be rotated by the baffle 7, and at the same time drive the rotating block 8 and the abutment blocks 9 to rotate for use.

[0024] Furthermore, a groove 11 is provided in the middle of the interior of the fixing block 10, and a spring 12 is provided in the middle of the inner wall of the groove 11. A slider 13 is slidably arranged in the groove 11. The end of the spring 12 abuts against the slider 13. A pull rod 14 is fixedly connected to the upper end of the slider 13. This structure can move the slider 13 as a whole in the inner wall of the groove 11 by pulling the pull rod 14, thereby allowing the limiting block 17 to disengage from the fitting range of the abutment block 9.

[0025] Furthermore, the limiting component includes a slot 15. The slot 15 is provided in the middle of the interior of the slider 13. A limiting block 17 is rotatably provided in the middle of the inner wall of the slot 15 via a rotating shaft. A torsion spring 16 is provided on the rotating shaft of the limiting block 17. The surface of the limiting block 17 abuts against the surface of the abutment block 9. The limiting block 17 can only rotate backward in the slot 15, that is, towards the side of the plastic granule production equipment 1. When the limiting block 17 rotates towards the side of the baffle 7, it will abut against the inner wall of the slot 15 and be limited. Therefore, during use, the baffle 7 can rotate closer to the opening of the lower feed channel 2, which can adjust the feed opening diameter. However, it cannot be increased by rotating the baffle 7 to avoid material impact, which would cause the baffle 7 to shift and expand. When adjusting, the baffle 7 is first adjusted from a large diameter to a small diameter according to the size of the feed granules. This structure can make the baffle 7 be used at different flip angles through the abutment between the limiting block 17 and the abutment block 9.

[0026] Working principle: When in use, the angle of the baffle 7 is adjusted. When adjusting the baffle 7, the pull rod 14 is pulled to move the slider 13 to squeeze the spring 12. At the same time, the limiting block 17 will move, thus disengaging from the position of abutting the block 9. Then the angle of the baffle 7 can be adjusted. After that, the spring 12 will be compressed and the limiting block 17 will be abutted against the block 9 again. Then the baffle 7 can be pressed inward to rotate it, so that the opening diameter of the feed channel 2 is reduced. The rotation of the baffle 7 drives the block 9 to rotate. The block 9 will push the limiting block 17. After rotating to a certain angle, the limiting block 17 will return to the initial position through the torsion spring 16, and the surface of the limiting block 17 will abut against the surface of the torsion spring 16, thereby stabilizing the position of the baffle 7 after rotation.

[0027] At this point, the vacuum cleaner 3 is turned on to adsorb the particles. The vacuum cleaner 3 is a mature existing technology and will not be described in detail here. Afterwards, the plastic granule production equipment 1 discharges the plastic granules through the feeding channel 2. During the descent, the granules impact the surface of the baffle 5, causing the dust on the surface of the plastic granules to fall off. As the granules pass through the end of the vacuum cleaner 3, the dust is absorbed and drawn into the vacuum cleaner 3. During the impact, any static electricity that may be generated on the surface of the plastic granules is conducted. This static electricity is conducted through the baffle 5 and the rotating shaft on the upper side of the baffle 5 to the conductive block 6, and is then transmitted to the ground to eliminate the static electricity. Afterwards, the plastic granules fall to the end of the feeding channel 2 and impact the surface of the baffle 7, causing the baffle 7 to vibrate. This vibration causes the entire feeding channel 2 to vibrate partially, allowing the falling plastic granules to fall in a flat state, reducing the stacking state. This allows the surface dust to be better absorbed by the vacuum cleaner 3. The above is the complete working principle of this utility model.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
