Technical Field

[0001] The utility model relates to the technical field of recovery devices, in particular to a particle recovery device for a plastic granulator. Background Art

[0002] With the continuous development of plastic recycling technology, plastic granulators have been widely used in the reprocessing of plastic waste, processing plastic waste into granules for the production of various plastic products. However, the existing plastic granulators still have some significant deficiencies in the plastic granule recycling operation at the end;

[0003] Currently, the recycling devices of most plastic granulators use manual operation to collect and bag the granules. During the production process, the plastic granules output by the granulator need to be manually hung with the bag at the outlet of the plastic granules. This process often requires workers to manually monitor the granule collection and be ready to replace the bag filled with granules at any time. Due to the large and continuous production volume of granules, the frequency of manual bag replacement is very high, and the replacement process often takes a long time, resulting in interruptions and stagnation of the production line, thereby affecting production efficiency.

[0004] Moreover, after the material bag is full, it is necessary to manually replace the material bag. During this period, the operation of the plastic granulator cannot be stopped, which will cause a large amount of plastic particles to fall to the ground, resulting in material waste.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1 -6. A particle recovery device for a plastic granulator, comprising a device base 100 and a screening mechanism and a rotating material receiving mechanism provided on the device base 100;

[0026] The rotating material receiving mechanism includes a driving motor 201, a main frame 202, a rotating table 203 and a bag mounting frame 300. The main frame 202 is fixedly connected to the device base 100, and the rotating table 203 is rotatably connected to the main frame 202. The driving motor 201 is fixedly connected to the main frame 202, and the driving motor 201 is connected to the rotating table 203. A plurality of bag mounting frames 300 are fixedly connected to the rotating table 203 in a circular array. The bag mounting frames 300 are equipped with a charging bag 400. In this way, the driving motor 201 can drive the rotating table 203 to rotate, thereby rotating the bag mounting frame 300.

[0027] More specifically, the bag mounting frame 300 includes a bottom supporting platform 301, a universal wheel 302, a bag opening extrusion platform 303, and a bag opening support ring 304. That is, a connecting frame 305 is fixedly connected to the rotating platform 203, a bag opening support ring 304 is fixedly connected to the connecting frame 305 near its top, a bag opening extrusion platform 303 is hingedly connected to one side of the bag opening support ring 304 on the connecting frame 305, an extrusion groove 306 is provided on the bag opening extrusion platform 303, a bottom supporting platform 301 is fixedly connected to the connecting frame 305 near its bottom, and the bottom surface of the bottom supporting platform 301 is fixedly connected to the bottom of the bottom supporting platform 301. The universal wheel 302 is fixedly connected and contacts the device base 100. When installing the charging bag 400, the bag opening of the charging bag 400 can be unfolded and placed on the bag opening support ring 304. Then, by rotating the bag opening squeezing platform 303, the bag opening squeezing platform 303 and the bag opening support ring 304 squeeze and fix the bag opening of the charging bag 400. The bottom of the charging bag 400 is located on the bottom support platform 301, so that when the charging bag 400 is loaded, the bottom support platform 301 supports the charging bag 400 to prevent the charging bag 400 from falling.

[0028] Furthermore, in this embodiment, the screening mechanism includes a screening net 501, a screening box 502, and a waste collection bag 503. The screening box 502 is fixedly connected to the device base 100. The screening net 501 is elastically connected in an inclined structure in the screening box 502. The elastic connection structure here is that multiple sets of mounting side platforms 504 are fixedly connected in the screening box 502. The mounting side platforms 504 are fixedly connected to the springs 505. The ends of the springs 505 are fixedly connected to the screening net 501.

[0029] The screening box 502 is provided with a discharge port at the lower end position corresponding to the screening net 501, and the discharge port corresponds to a group of feeding bags 400. Optimally, a guide frame 506 is fixedly connected to the discharge port, and a discharge port is provided on the guide frame 506, and the discharge port corresponds to a group of feeding bags 400. A feed port 507 is provided at the upper end position corresponding to the screening net 501 on the screening box 502, and a waste discharge port 508 is provided at the bottom of the screening net 501 on the screening box 502, and a waste collection bag 500 is fixedly connected to the waste discharge port 508. 03, the plastic particles produced by the plastic granulator can enter the screening box 502 through the feed port 507. At this time, the plastic particles can be screened by the screening net 501, so that the broken materials are screened out and enter the waste collection bag 503 at the bottom. The screened plastic particles fall into the corresponding charging bag 400 due to gravity. After the plastic particles enter the screening box 502, the plastic particles can impact the screening net 501, causing the screening net 501 to vibrate, thereby improving the screening efficiency.

[0030] Furthermore, a closing component 600 is provided on the material guide frame 506 corresponding to the discharge port. The closing component 600 includes an electric telescopic cylinder 601, a fixed frame 602, and a closing plate 603. The material guide frame 506 is fixedly connected to the fixed frame 602 corresponding to the discharge port. The fixed frame 602 is fixedly connected to the electric telescopic cylinder 601. The piston end of the electric telescopic cylinder 601 is fixedly connected to the closing plate 603. The closing plate 603 corresponds to the discharge port. In this way, the electric telescopic cylinder 601 can drive the closing plate 603 to move, thereby realizing the opening and closing control of the discharge port by the closing plate 603.

[0031] Furthermore, a detection sensor 700 is fixedly connected to the fixed frame 602. The detection sensor 700 corresponds to the interior of the charging bag 400. Here, the detection sensor 700 can be an ultrasonic sensor or an infrared sensor. The detection sensor 700 is used to detect the amount of material in the charging bag 400.

[0032] Finally, it also includes a PLC controller and a motor driver connected to the PLC controller signal, the motor driver is connected to the drive motor 201 and the electric telescopic cylinder 601 signal, and the detection sensor 700 is connected to the PLC controller signal;

[0033] In summary, the plastic particles produced by the plastic granulator can enter the screening box 502, and the plastic particles are screened by the screening net 501 in the screening box 502. The screened plastic particles can be guided by the guide frame 506 to enter the corresponding charging bag 400. The charging amount in the charging bag 400 can be detected in real time by the detection sensor 700. When the detected charging bag 400 reaches the set amount, the PLC controller can control the electric telescopic cylinder 601 to work. At this time, the closing plate 603 closes the discharge port. Then the PLC controller can control the drive motor 201 to work. At this time, the drive motor 201 drives the rotating table 203 to rotate a certain angle, so that another group of charging bags 400 correspond to the discharge port. Then the electric telescopic cylinder 601 opens the closing plate 603, so that the screened plastic particles can re-enter the new charging bag 400.
