Description

Technical Field

[0001] This utility model relates to the field of automotive modified plastic particle screening technology, specifically to a vibration sorting device for automotive modified plastic particles. Background Technology

[0002] Modified plastic particles for automobiles are materials produced by physically or chemically modifying general-purpose or engineering plastics. Common types include modified polypropylene, modified polypropylene, and modified acrylonitrile. These modifications can improve the flame retardancy, strength, and impact resistance of the materials. During the production process, modified plastic particles for automobiles require vibration sorting to physically isolate incompletely melted raw materials, additive residues, or debris generated by mechanical wear, thereby reducing the impact of impurities on product quality.

[0003] According to the Chinese patent publication CN212468757U, "A Modified Plastic Particle Vibration Sorting Device", it mainly describes that when the screen is blocked, the air pipe frame can be quickly pulled back and forth by a pull rod, so that the air pipe frame can spray air from the bottom of the screen to quickly clear the blockage. The operation is simple and quick. When clearing, the baffles on both sides of the air pipe frame can block the slide chute to prevent material leakage. When not in use, the air pipe frame can be fixed by slots and bolts to prevent the air pipe frame from shaking on the main body during screening and affecting normal operation.

[0004] Commonly used vibration sorting for modified plastics in automobiles involves multi-layer screen structures for vibration screening, combined with a dust removal structure to reduce dust dispersion during vibration. However, some modified plastic particles in automobiles have high moisture content, which can cause agglomeration between particles, resulting in uneven sorting and affecting screening efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a vibration sorting device for modified plastic particles used in automobiles, which reduces uneven sorting of modified plastic particles during the vibration screening process and improves screening efficiency.

[0006] The technical solution adopted by this utility model to solve the technical problem is: a vibration sorting device for modified plastic particles for automobiles, including a base plate, a buffer rod, a screening frame, a discharge port, a first motor, a rotating rod, and an eccentric block. The screening frame has first grooves on both sides, with a limiting rod fixedly connected in each groove. A slider is sleeved on the limiting rod. Two opposing sliders are rotatably connected to a connecting frame via a rotating shaft. A screen plate is inserted into the connecting frame. The screen plate is inclined, and a positioning rod is contacted on the lower side of the screen plate. The positioning rod is threadedly connected to the connecting frame. A baffle is fixedly connected to one side of the upper end of the screening frame. Three outlets facing different directions are fixedly connected to one end of the baffle. The screening frame has a second groove, and a second motor is fixedly connected to one side of the screening frame in the second groove. A bidirectional lead screw is fixedly connected to the output end of the second motor. Slide plates are threadedly connected to both sides of the bidirectional lead screw. A third motor is fixedly connected to the slide plate on the side away from the screen plate. A crushing roller is fixedly connected to the output end of the third motor, and the crushing roller is located on the bottom side of the discharge port.

[0007] As a preferred technical solution of this utility model, a dust-blocking brush is in contact with the upper side of the crushing roller, and a baffle is fixedly connected to the upper end of the dust-blocking brush. The upper side of the baffle is rotatably connected to the screening frame through a rotating shaft. The baffle is located on both sides of the bottom end of the feed port. By setting the baffle and the dust-blocking brush, the falling material can be blocked, ensuring that the material falls through the gap between the two crushing rollers.

[0008] As a preferred technical solution of this utility model, a folding cover is provided between the two crushing rollers, and two sliding plates are fixedly connected to the two ends of the folding cover. By setting the folding cover, the impact of the crushed material being ejected from the screening frame can be reduced.

[0009] As a preferred technical solution of this utility model, a third groove is provided on both sides of the screening frame. A filter cylinder is fixedly connected to one side of one of the third grooves, and the filter cylinder is equipped with an air pump. A dust-blocking net is fixedly connected to the other third groove. The air pump is used to remove the vibration dust in the screening frame that affects the environment.

[0010] As a preferred technical solution of this utility model, the filter cylinder is fixedly connected to the filter screen on the upper side of the third groove, and the upper side of the filter cylinder is connected to the sealing plate by a hinge. The sealing plate is fixedly connected to the air pump. The air pump drives the airflow in the screening frame and collects the dust generated by vibration.

[0011] This utility model has the following advantages: by cooperating with the rotation of the three screen plates of the screening frame and the eccentric block, a multi-stage vibrating screening of materials is formed. Then, the baffle frame and the outlet reduce the dust overflow caused by vibration. The air pump draws the gas in the screening frame and adsorbs it into the screening frame through the third groove, thereby facilitating the collection of vibration dust and improving the environmental quality at the screening frame. Furthermore, by installing a relatively movable and adjustable sliding plate and a rotatable crushing roller on the bottom side of the discharge port to squeeze the adhered plastic particles, the sorting effect of plastic particles is improved.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Please refer to the following: Figure 1-5The device shown is a vibration sorting device for modified plastic particles used in automobiles. It includes a base plate 1, a buffer rod 2, a screening frame 3, a discharge port 4, a first motor, a rotating rod, and an eccentric block 11. The first motor drives the rotating rod and eccentric block 11 to rotate. The edge of the eccentric block 11 contacts the connecting frame 8, causing the three connecting frames 8 to vibrate and facilitating material screening. The screening frame 3 has a first groove 5 on both sides (the first groove 5 has a structure similar to the folding cover 17, not shown in the figure, to prevent plastic particles from overflowing from the first groove 5). A limiting rod 6 is fixedly connected inside the first groove 5. A slider 7 is sleeved on the limiting rod 6. Two opposing sliders 7 are rotatably connected to the connecting frame 8 via a rotating shaft. A screen plate 9 is inserted into the connecting frame 8. The screen plate 9 is inclined, and a positioning rod 10 is contacted on the lower side of the screen plate 9. Removing the positioning rod 10 allows the screen plate 9 to detach from the connecting frame 8 for easy replacement. The positioning rod 10 is threadedly connected to the connecting frame 8. The upper side of the screening frame 3 is fixed... A baffle frame 12 is fixedly connected to the screen 3. The baffle frame 12 provides guidance for the graded plastic particles and reduces the exposed surface of the screen 3, thus reducing dust overflow. Three outlets 13 with different orientations are fixedly connected to one end of the baffle frame 12. A second groove 23 is opened in the screen 3. A second motor is fixedly connected to one side of the screen 3 located in the second groove 23. The second motor drives the bidirectional lead screw 14 to rotate, which can cause the two slide plates 15 to move relative to each other and make the gap between the two crushing rollers 16 adjustable, thereby providing corresponding adaptability according to different plastic particle sizes. The second motor can be controlled and adjusted by observing the discharge port 4. The output end of the second motor is fixedly connected to the bidirectional lead screw 14. Slide plates 15 are threadedly connected to both sides of the bidirectional lead screw 14. A third motor is fixedly connected to the side of the slide plate 15 away from the screen plate 9. The two third motors have a linkage structure to control relative movement. The output end of the third motor is fixedly connected to the crushing roller 16, which is located on the bottom side of the discharge port 4.

[0020] The upper side of the crushing roller 16 is in contact with a dust-blocking brush, and the upper end of the dust-blocking brush is fixedly connected to a baffle 18. The upper side of the baffle 18 is rotatably connected to the screening frame 3 through a rotating shaft. The baffle 18 is located on both sides of the bottom end of the discharge port 4. By setting the dust-blocking brush and the baffle 18, the plastic particles can be guided to the gap between the two crushing rollers 16.

[0021] A folding cover 17 is provided between the two crushing rollers 16. Two sliding plates 15 are fixedly connected to the two ends of the folding cover 17. By providing the folding cover 17, plastic particles that are splashed by the pressure of the crushing rollers 16 can be prevented from overflowing from the second groove 23.

[0022] The screening frame 3 has a third groove 19 on both sides. A filter cylinder 21 is fixedly connected to one side of one of the third grooves 19. An air pump 22 is installed at the upper end of the filter cylinder 21. A dust filter 20 is fixedly connected to the other third groove 19. By setting the air pump 22 to generate suction, the dust in the screening frame 3 enters the filter cylinder 21 from the third groove 19.

[0023] The filter cylinder 21 is fixedly connected to the filter screen on the upper side of the third groove 19. The upper side of the filter cylinder 21 is connected to the sealing plate by a hinge. The sealing plate is fixedly connected to the air pump 22. The air inlet of the air pump 22 is located inside the filter cylinder 21. By setting the filter screen, the direct contact between dust and the port of the air pump 22 is reduced.

[0024] Working principle: The second motor drives the bidirectional lead screw 14 to rotate according to the maximum diameter of the plastic particles to be screened, and causes the two crushing rollers 16 to move relative to each other. The length of the gap is observed manually from the feed port 4. Then, plastic particles are fed in. The plastic particles are blocked by the baffle 18 and fall through the gap of the crushing rollers 16. At the same time, the plastic particles that are stuck together are crushed by the rotating crushing rollers 16 and fall onto the screen plate 9. Meanwhile, the first motor drives the screening frame 3 to vibrate. Then, the plastic particles vibrate and move downward, and then move out through different outlets 13. During this process, the air pump 22 is started and the dust in the screening frame 3 flows from the outlet 13 and the third groove 19 into the filter cylinder 21, thereby achieving the filtration effect.

[0025] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0026] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
