[0016] S2: When the plastic particles pass under the water collection box, the clean water in the water collection tank is pumped into the water collection box through a water pump and a hose, and then sprayed out through a cleaning nozzle installed at the bottom of the water collection box to wash the plastic particles passing through and remove the plastic particles adhering to the surface of the plastic particles;

[0018] The beneficial effects of the present invention are:

[0019] 1. The plastic particles are conveyed toward the water collection box through the first filter belt. When the plastic particles pass under the water collection box, the clean water in the water collection box is pumped into the water collection box through the water pump and the hose, and then sprayed out through the cleaning nozzle installed at the bottom of the water collection box to wash the passing plastic particles, so as to remove the plastic particles adhering to the surface of the plastic particles and improve the cleanliness of the surface of the plastic particles;

[0020] 2. The plastic particles falling on the surface of the second filter belt are transported to the direction of the second discharge hopper through the second filter belt. Since the scraper installed on the inner side of the second discharge hopper is in contact with the outer side of the second filter belt, the plastic particles adhering to the surface of the second filter belt can be scraped off by the scraper into the second discharge hopper and discharged and collected, so as to be recycled later;

[0021] 3. When the first roller rotates, it will drive the hook plate to rotate synchronously. When the hook plate rotates to the guide column, the guide column will be stuck in the arc groove opened on the side of the hook plate, so that when the hook plate continues to rotate, it can pull the cleaning box as a whole downward through the guide column, so that the multiple spring rods supporting the cleaning box will shrink. After the hook plate passes over the guide column, the cleaning box will bounce up and reset under the elastic force of the spring rod, so that the cleaning box can produce longitudinal shaking to avoid the accumulation of plastic particles, so as to improve the filtration efficiency of the first filter belt and the second filter belt for plastic particles and plastic microparticles.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] See attached Figure 1 -Attached Figure 7, a device for producing plastic particles, comprising a water collecting box 1, a plurality of spring rods 2 are evenly fixedly installed on the bottom wall of the water collecting box 1, a cleaning box 3 is fixedly installed between the telescopic ends of the plurality of spring rods 2, a door frame 8 is fixedly installed on the top of the cleaning box 3, a water collecting box 9 is fixedly installed through the top of the door frame 8, a plurality of cleaning nozzles are evenly fixedly installed on the bottom end of the water collecting box 9, two first rollers 4 are rotatably installed between the inner walls on opposite sides of the cleaning box 3, the outer surfaces of the two first rollers 4 are sleeved with a first filter belt 5, a first discharge hopper 10 is fixedly installed through one end of the water collecting box 1 located below the first filter belt 5, a recovery mechanism is installed inside the cleaning box 3 located below the first filter belt 5, a water pump 19 is fixedly installed on the bottom wall of the water collecting box 1, and a hose 20 connected to each other is fixedly installed between the water outlet end of the water pump 19 and the water collecting box 9.

[0033] In this embodiment, the recovery mechanism includes two second rollers 6 rotatably installed between the inner walls of the cleaning box 3 on both sides. The outer surfaces of the two second rollers 6 are sleeved with a second filter belt 7. The outer surfaces of the first filter belt 5 and the second filter belt 7 are penetrated with a plurality of filter holes. The aperture of the filter holes on the second filter belt 7 is smaller than the aperture of the filter holes on the first filter belt 5. A second discharge hopper 11 is fixedly installed on one end of the cleaning box 3 located below the second filter belt 7. A scraper 14 is fixedly installed on the inner wall of the second discharge hopper 11. The top of the scraper 14 is in contact with the outer surface of the second filter belt 7. An anti-blocking component for cleaning the filter holes on the second filter belt 7 is installed inside the cleaning box 3 near the second discharge hopper 11.

[0034] When in use, the plastic particles washed off the surface of the plastic particles will pass through the filter holes of the first filter belt 5 and fall onto the second filter belt 7, so that the second filter belt 7 filters the plastic particles. Since the first roller 4 and the second roller 6 are driven by the pulley 21 and the transmission belt 22, the first roller 4 can drive the second filter belt 7 to move through the second roller 6 when it rotates, so that the second filter belt 7 can transfer the plastic particles falling on its surface to the direction of the second discharge hopper 11. Since the scraper 14 installed on the inner side of the second discharge hopper 11 is in contact with the outer side of the second filter belt 7, the plastic particles adhered to the surface of the second filter belt 7 can be scraped by the scraper 14 into the second discharge hopper 11 and discharged and collected, so that the plastic particles can be recycled later.

[0035] In this embodiment, the anti-blocking component includes an air pipe 12 fixedly installed between the inner walls on both sides of the cleaning box 3, and a plurality of air blowing nozzles are evenly and fixedly installed on the lower surface of the air pipe 12. The air pipe 12 is arranged on the inner side of the second filter belt 7, and the air blowing nozzle is arranged downward. An air pump 13 is fixedly installed on the outer surface of the cleaning box 3, and the air outlet end of the air pump 13 is connected to the interior of the air pipe 12. A beating component is installed inside the cleaning box 3 near the air pipe 12.

[0036] When in use, air is injected into the air pipe 12 through the air pump 13, so that air is ejected from multiple blowing nozzles installed at the bottom of the air pipe 12, so as to back-blow the filter holes on the second filter belt 7 to prevent plastic particles from clogging the filter holes and affecting the subsequent filtering effect.

[0037] In this embodiment, the beating assembly includes a rotating rod 15 that is rotatably installed between the inner walls of the cleaning box 3 on both sides. A plurality of door-type beating rods 16 are evenly rotatably installed on the outer periphery of the rotating rod 15. The rotating rod 15 is arranged on the inner side of the second filter belt 7. A transmission assembly is installed between the rotating rod 15 and the water collecting box 1. The transmission assembly includes a transmission gear 17 fixedly installed on the two end portions of the rotating rod 15. A transmission rack 18 is fixedly installed on the bottom wall of the water collecting box 1, and the transmission rack 18 is meshed with the transmission gear 17.

[0038] When the cleaning box 3 moves up and down, it will drive the transmission gear 17 to roll back and forth on the transmission rack 18, so that the transmission gear 17 can drive the door-type beating rod 16 to swing back and forth through the rotating rod 15, so that the door-type beating rod 16 can beat the upper and lower sides of the second filter belt 7 to prevent plastic particles from being stuck in the filter holes and affecting the filtering effect.

[0039] In this embodiment, a moving mechanism is installed between one of the first rollers 4 and the water collecting box 1, and the moving mechanism includes a hook plate 24 fixedly installed at the rotation center of one of the first rollers 4, and an arc groove 25 is provided on the outer surface of the hook plate 24 close to the cleaning box 3. A vertical plate 26 is fixedly installed on the bottom wall of the water collecting box 1, and a guide column 27 is fixedly installed on the outer surface of the vertical plate 26 close to the hook plate 24, and the guide column 27 intermittently contacts the inner wall of the arc groove 25.

[0040] When the first roller 4 rotates, the hook plate 24 will be driven to rotate synchronously. When the hook plate 24 rotates to the guide post 27, the guide post 27 will be stuck in the arc groove 25 opened on the side of the hook plate 24, so that when the hook plate 24 continues to rotate, the cleaning box 3 can be pulled downward as a whole through the guide post 27, so that the multiple spring rods 2 supporting the cleaning box 3 will shrink. After the hook plate 24 passes over the guide post 27, the cleaning box 3 will bounce up and reset under the elastic force of the spring rod 2, so that the cleaning box 3 can generate longitudinal shaking to avoid the accumulation of plastic particles, so that the first filter belt 5 and the second filter belt 7 can better filter the plastic particles and plastic microparticles.

[0041] In this embodiment, a pulley 21 is fixedly installed at the rotation center of one of the first rollers 4 and a second roller 6 at the corresponding position, and a transmission belt 22 is sleeved on the outer surfaces of the two pulleys 21. A driving motor 23 is fixedly installed on the outer surface of the cleaning box 3, and the output end of the driving motor 23 passes through the inner wall of the cleaning box 3 and is fixedly installed with the rotation center of one of the first rollers 4.

[0042] When in use, the first roller 4 is driven to rotate by the driving motor 23, so that the first roller 4 can drive the first filter belt 5 to move. Since the first roller 4 and the second roller 6 are transmitted through the pulley 21 and the transmission belt 22, the first roller 4 can drive the second filter belt 7 to move through the second roller 6 when rotating.

[0043] A method for using a device for producing plastic particles comprises the following steps:

[0044] S1: Pour the produced plastic particles into the cleaning box 3 from the end away from the first discharge hopper 10, so that the plastic particles fall onto the first filter belt 5 installed in the cleaning box 3, and the first filter belt 5 conveys the plastic particles to the water collecting box 9;

[0045] S2: When the plastic particles pass under the water collecting box 9, the clean water in the water collecting box 1 is pumped into the water collecting box 9 through the water pump 19 and the hose 20, and then sprayed out through the cleaning nozzle installed at the bottom of the water collecting box 9 to wash the plastic particles passing through and remove the plastic particles adhering to the surface of the plastic particles;

[0046] S3: The plastic particles washed off the surface of the plastic particles will pass through the filter holes of the first filter belt 5 and fall onto the second filter belt 7, so that the second filter belt 7 will filter the plastic particles, and the plastic particles falling on its surface will be transported toward the second discharge hopper 11 through the second filter belt 7, so that the plastic particles adhered to the surface of the second filter belt 7 will be scraped by the scraper 14 into the second discharge hopper 11 and discharged and collected, so that the plastic particles can be recycled.

[0047] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when in use, the produced plastic particles are poured into the cleaning box 3 from the end away from the first discharge hopper 10, so that the plastic particles fall onto the first filter belt 5 installed in the cleaning box 3, and the first filter belt 5 conveys the plastic particles to the direction of the water collecting box 9. When the plastic particles pass under the water collecting box 9, the clean water in the water collecting box 1 is pumped into the water collecting box 9 by the water pump 19 and the hose 20, and then sprayed out by the cleaning nozzle installed at the bottom of the water collecting box 9 to rinse the plastic particles passing through, so as to remove the plastic particles adhered to the surface of the plastic particles and improve the cleanliness of the surface of the plastic particles; the cleaned plastic particles are discharged and collected from the first discharge hopper 10, and the collected plastic particles are packaged and stored after being air-dried;

[0048] The plastic particles washed from the surface of the plastic particles will pass through the filter holes of the first filter belt 5 and fall onto the second filter belt 7, so that the second filter belt 7 filters the plastic particles. Since the first roller 4 and the second roller 6 are driven by the pulley 21 and the transmission belt 22, the first roller 4 can drive the second filter belt 7 to move through the second roller 6 when rotating, so that the second filter belt 7 can transfer the plastic particles falling on its surface to the direction of the second discharge hopper 11. Since the scraper 14 installed on the inner side of the second discharge hopper 11 is attached to the outer side of the second filter belt 7, the plastic particles adhered to the surface of the second filter belt 7 can be scraped by the scraper 14 into the second discharge hopper 11 and discharged and collected, so as to be recycled and reused later.

[0049] When the first roller 4 rotates, the hook plate 24 will be driven to rotate synchronously. When the hook plate 24 rotates to the guide post 27, the guide post 27 will be stuck in the arc groove 25 opened on the side of the hook plate 24, so that when the hook plate 24 continues to rotate, the cleaning box 3 can be pulled downward as a whole through the guide post 27, so that the multiple spring rods 2 supporting the cleaning box 3 are contracted. After the hook plate 24 passes over the guide post 27, the cleaning box 3 will bounce up and reset under the elastic force of the spring rod 2, so that the cleaning box 3 can generate longitudinal shaking to avoid the accumulation of plastic particles, so that the first filter belt 5 and the second filter belt 7 can better filter the plastic particles and plastic microparticles;

[0050] Air is injected into the air pipe 12 through the air pump 13, so that the air is ejected from multiple air blowing nozzles installed at the bottom of the air pipe 12, so as to back-blow the filter holes on the second filter belt 7 to prevent the plastic particles from clogging the filter holes and affecting the subsequent filtering effect;

[0051] When the cleaning box 3 moves up and down, it will drive the transmission gear 17 to roll back and forth on the transmission rack 18, so that the transmission gear 17 can drive the door-type beating rod 16 to swing back and forth through the rotating rod 15, so that the door-type beating rod 16 can beat the upper and lower sides of the second filter belt 7 to prevent plastic particles from being stuck in the filter holes and affecting the filtering effect.

[0052] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
