Description

Technical Field

[0001] The utility model belongs to the technical field of plastic recycling. Specifically, it particularly relates to a plastic recycling and crushing device with a surface dust removal function. Background Art

[0002] Recycling plastics can help save natural resources and avoid over-exploitation and environmental pollution. In order to facilitate the subsequent transportation and secondary processing of recycled plastics, it is necessary to break the recycled plastics through a plastic crusher when recycling plastics.

[0003] When recycling plastics, some plastics will adhere to dust on their surfaces. This phenomenon causes the dust to mix with the plastic fragments after the plastics are broken by the crushing device. As a result, when melting the plastic fragments, the dust on the plastic fragments is likely to mix with the molten plastic liquid, which makes it impossible to guarantee the quality of the products when injecting the products with the plastic liquid.

[0004] Regarding the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0005] Regarding the problems in the related art, the utility model proposes a plastic recycling and crushing device with a surface dust removal function to overcome the above-mentioned technical problems existing in the existing related art.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a plastic recycling and crushing device with a surface dust removal function, including a crushing box. A crushing component is arranged inside the crushing box. A material blocking component is arranged at the bottom of the crushing component. Extraction components are arranged on both sides of the crushing box corresponding to the material blocking component. A collection component is arranged on one side of the material blocking component.

[0008] Further, the crushing component includes crushing rollers. Two crushing rollers are arranged staggeredly. The shaft heads of the crushing rollers are rotationally connected to the crushing box. Fixedly connected to the outer surfaces of the shaft heads of the two crushing rollers are gears. The two gears are meshed with each other. A motor is fixedly installed on one side of the crushing box. The output end of the motor is fixedly connected to the shaft head of the crushing roller.

[0009] Further, the material blocking component includes an inclined material guiding plate. The bottom end of the inclined material guiding plate is fixedly connected with an arc-shaped plate. Two inclined material guiding plates and arc-shaped plates are symmetrically arranged. A rotating shaft is rotationally connected to the inner wall of the crushing box. A material blocking plate is fixedly connected to the outer surface of the rotating shaft. The material blocking plate is movably connected to the inner wall of the arc-shaped plate.

[0010] Further, the material blocking assembly further includes transmission wheels, which are arranged on the outer surfaces of the crushing roller shaft heads and the rotating shafts respectively, and transmission belts are arranged on the outer surfaces of the transmission wheels.

[0011] Further, the extraction assembly includes a connecting sealing plate, both sides of the connecting sealing plate are connected to the arc-shaped plate and the crushing box respectively. There are two connecting sealing plates arranged up and down at the rear side of the arc-shaped plate. Filter holes are formed in the inner wall of the arc-shaped plate, and an air extraction pipe is arranged on the inner wall of the crushing box corresponding to the arc-shaped plate. One end of the air extraction pipe is fixedly connected to an air extractor.

[0012] Further, the collection assembly includes a collection box. A through groove is formed on one side of the crushing box corresponding to the arc-shaped plate and the connecting sealing plate. The collection box is movably connected to the through groove. Vent holes are formed in the inner wall of the collection box.

[0014] The utility model has the following beneficial effects:

[0015] 1. The plastic can be broken by the crushing assembly of the utility model. At the same time, the vibration force generated during the crushing process can make the dust fall off from the surface of the plastic. When the plastic fragments fall to the material blocking assembly, the material blocking assembly can block the plastic fragments briefly. At this time, the extraction assembly can adsorb the dust on the plastic fragments and make the collection assembly collect the dust, so that the dust on the surface of the plastic can be cleaned after being broken, thus improving the quality of the product when the liquid obtained by melting the plastic fragments is used for product injection molding.

[0016] 2. The plastic fragments broken by the inclined guide plate can directly fall between the two arc-shaped plates. At this time, the rotating shaft drives the plastic fragments to rotate inside the arc-shaped plate through the baffle. At this time, the air extractor adsorbs and cleans the dust on the plastic fragments through the air extraction pipe and the filter holes. Coupled with the baffle contacting the inner wall of the arc-shaped plate, the rotating baffle can scrape the plastic fragments adsorbed at the filter holes, so that the plastic fragments will not block the filter holes due to the suction force.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the utility model with reference to the attached drawings in the embodiments of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, rather than all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the utility model.

[0028] In the description of the present utility model, it should be understood that terms such as "opening", "upper", "lower", "top", "middle", "inner", etc. indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the utility model.

[0029] Please refer to Figures 1-6 As shown, the present utility model is a plastic recycling and crushing device with a surface dust removal function, including a crushing box 1. A crushing component 2 is arranged inside the crushing box 1. A material blocking component 3 is arranged at the bottom of the crushing component 2. Extraction components 4 are arranged on both sides of the crushing box 1 corresponding to the material blocking component 3. A collection component 5 is arranged on one side of the material blocking component 3.

[0030] After the recycled plastic is put into the interior of the crushing box 1, the plastic can be crushed after passing through the crushing component 2. At this time, the material blocking component 3 can temporarily block the crushed plastic, so that the extraction component 4 can adsorb the dust on the plastic fragments and the collection component 5 can collect the adsorbed dust.

[0031] The recycling plastic can be broken by the crushing component 2. During the process of the crushing component 2 breaking the plastic, the dust on the surface of the plastic will fall off from the plastic surface under the influence of the vibration force. At the same time, under the temporary block of the material blocking component 3, the extraction component 4 can suck the dust inside the plastic fragments and the collection component 5 can collect the dust. The above settings enable the dust on the surface of the recycled plastic to be cleaned when the plastic is broken, so that the quality of the product can be improved when the liquid obtained by melting the plastic fragments is used for product injection molding.

[0032] In one embodiment, for the above-mentioned crushing component 2, the crushing component 2 includes two crushing rollers 201 arranged staggeredly. The shaft heads of the crushing rollers 201 are rotatably connected to the crushing box 1. Fixedly connected to the outer surfaces of the shaft heads of the two crushing rollers 201 are gears 202. The two gears 202 mesh with each other. A motor 203 is fixedly installed on one side of the crushing box 1. The output end of the motor 203 is fixedly connected to the shaft head of the crushing roller 201.

[0033] By starting the motor 203, the motor 203 drives the corresponding crushing roller 201 to rotate. The rotating crushing roller 201 drives the other crushing roller 201 to rotate through two meshing gears. The cooperation of the two rotating crushing rollers 201 can break the shredded materials put into the interior of the crushing box 1.

[0034] In one embodiment, for the above-mentioned material blocking assembly 3, the material blocking assembly 3 includes an inclined material guiding plate 301, the bottom end of the inclined material guiding plate 301 is fixedly connected with an arc-shaped plate 302, and there are two sets of the inclined material guiding plate 301 and the arc-shaped plate 302 which are symmetrically arranged. A rotating shaft 303 is rotatably connected to the inner wall of the crushing box 1, a material blocking plate 304 is fixedly connected to the outer surface of the rotating shaft 303, and the material blocking plate 304 is movably connected to the inner wall of the arc-shaped plate 302.

[0035] When the plastic fragments fall between the two crushing rollers 201 and then under the guidance of the inclined material guiding plate 301, the plastic fragments can directly fall into the interiors of the two arc-shaped plates 302. At this time, a plurality of material blocking plates 304 arranged on the outer surface of the rotating shaft 303 can block the plastic fragments. At the same time, as the rotating shaft 303 drives the plurality of material blocking plates 304 to rotate, the material blocking plates 304 can drive the blocked plastic fragments to rotate inside the arc-shaped plate 302 and finally fall from the bottom of the two arc-shaped plates 302. During the period when the material blocking plates 304 drive the plastic fragments to rotate inside the arc-shaped plate 302, the extraction assembly 4 can suck and clean the dust on the plastic fragments. The plastic fragments on the arc-shaped plate 302 and the material blocking plates 304 can stay between the two arc-shaped plates 302 for a period of time, so that the extraction assembly 4 can better adsorb and clean the dust.

[0036] In one embodiment, for the above-mentioned material blocking assembly 3, the material blocking assembly 3 further includes a transmission wheel 305, and the transmission wheel 305 is arranged on the shaft head of the crushing roller 201 and the outer surface of the rotating shaft 303, and a transmission belt 306 is arranged on the outer surface of the transmission wheel 305.

[0037] When the two crushing rollers 201 rotate to crush the plastic, the shaft head of one of the crushing rollers 201 can drive the transmission belt 306 to rotate through the transmission wheel 305, so that the transmission belt drives the rotating shaft 303 to rotate through the transmission wheel 305 on the rotating shaft 303. The above setting enables the rotating shaft 303 to rotate together with the crushing roller 201, so that the material blocking plate 304 can automatically rotate inside the two arc-shaped plates 302, and there is a certain linkage between the material blocking plate 304 and the crushing roller 201.

[0038] In one embodiment, for the above-mentioned extraction assembly 4, the extraction assembly 4 includes a connecting and sealing plate 401, both sides of the connecting and sealing plate 401 are connected to the arc-shaped plate 302 and the crushing box 1 respectively. There are two connecting and sealing plates 401 arranged up and down at the rear side of the arc-shaped plate 302. Filter holes 402 are formed in the inner wall of the arc-shaped plate 302, and an air extraction pipe 403 corresponding to the arc-shaped plate 302 is arranged on the inner wall of the crushing box 1, and one end of the air extraction pipe 403 is fixedly connected with an air extractor 404.

[0039] The two connecting and sealing plates 401 and the arc-shaped plate 302 can form a relatively airtight space with the inner wall of the crushing box 1. When the baffle plate 304 drives the plastic to rotate inside the arc-shaped plate 302, the air extractor 404 can extract the gas inside the airtight space through the air extraction pipe 403, so that the inside of the airtight space is in a negative pressure state, and the dust inside the two arc-shaped plates 302 can fall into the airtight space through the filter holes 402. At the same time, as the baffle plate 304 rotates, the baffle plate 304 can scrape off the plastic fragments adsorbed at the filter holes 402, so that the filter holes will not be blocked by the plastic fragments due to the suction force.

[0040] In one embodiment, for the above-mentioned collection assembly 5, the collection assembly 5 includes a collection box 501. A through groove 502 is provided on one side of the crushing box 1 corresponding to the arc-shaped plate 302 and the connecting and sealing plate 401. The collection box 501 is movably connected to the through groove 502. Vent holes 503 are provided on the inner wall of the collection box 501. A baffle 504 is fixedly connected to one side of the collection box 501, and a handle 505 is fixedly connected to one side of the baffle 504.

[0041] The air extraction pipe 403 can extract the air flow inside the airtight space and the collection box 501 through the vent holes 503, so that the dust between the two arc-shaped plates 302 can be adsorbed into the collection box 501. When cleaning the collected dust, directly pull the collection box 501 through the handle 505, so that the collection box 501 can drive the dust to move out from between the two connecting and sealing plates 401 through the through groove 502, which makes it more convenient to clean the collected dust. At the same time, when the collection box 501 is inside the crushing box 1, the baffle 504 can block the through groove 502, and this setting enables the inside of the collection box 501 to better form a negative pressure state.

[0042] In one embodiment, for the above-mentioned crushing box 1, a feed hopper 6 is fixedly connected to the top of the crushing box 1, and support legs 7 are fixedly connected to the bottom of the crushing box 1.

[0043] The recycled plastic can be conveniently put into the crushing box 1 through the feed hopper 6, and the setting of the support legs 7 makes there be a certain distance between the bottom of the crushing box 1 and the ground, and this setting makes it more convenient to collect the plastic fragments after cleaning the dust.

[0044] Through the above technical solutions: 1. The plastic can be broken by the crushing component 2, and at the same time, the vibration force generated during the crushing process can cause the dust to fall off the surface of the plastic. When the plastic fragments fall to the material blocking component 3, the material blocking component 3 can block the plastic fragments briefly. At this time, the extraction component 4 can adsorb the dust on the plastic fragments and enable the collection component 5 to collect the dust, so that the dust on the surface of the plastic can be cleaned after being broken, and the quality of the product can be improved when the liquid obtained by melting the plastic fragments is used for injection molding of the product; 2. After being broken by the inclined guide plate 301, the plastic fragments can directly fall between the two arc-shaped plates 302. At this time, the rotating shaft 303 drives the plastic fragments to rotate inside the arc-shaped plate 302 through the material blocking plate 304. At this time, the air extractor 404 adsorbs and cleans the dust on the plastic fragments through the air extraction pipe 403 and the filter holes 402. In addition, the material blocking plate 304 is in contact with the inner wall of the arc-shaped plate 302, so that the rotating material blocking plate 304 can scrape off the plastic fragments adsorbed at the filter holes 402, so that the plastic fragments will not block the filter holes due to the suction force.
