Description

Technical Field

[0001] The present invention belongs to the technical field of plastic recycling, and specifically relates to a waste plastic recycling and processing device. Background Art

[0002] Waste plastics refer to plastic products discarded due to loss of their original use value, including packaging materials (such as plastic bags, plastic bottles), electronic product casings, construction waste, agricultural films, etc. It should be particularly noted that the degradation of plastics is not complete mineralization, but is gradually cracked into microplastics (<5 mm) and even nanoplastics (<100 nm) through the effects of photooxidation, mechanical abrasion, etc. During this process, harmful substances such as phthalate esters and bisphenol A are released, posing multiple threats to the ecosystem and human health. Currently, for the convenience of transportation, plastic bottles are usually collected and compressed into blocks to reduce their volume. However, when compressing plastic bottles, some plastic bottles are in a sealed state due to the presence of bottle caps at their ends, and the gas inside the plastic bottles is difficult to discharge, resulting in difficulty in compressing the plastic bottles. Moreover, the sealed plastic bottles will burst under pressure, generating high-speed flying fragments and posing a safety hazard. Therefore, a waste plastic recycling and processing device is proposed. Summary of the Invention

[0005] Preferably, the conveying assembly includes a conveying roller arranged inside the cabin assembly. One end of the conveying roller is fixedly equipped with a first transmission gear, and an electric motor is fixedly installed outside the cabin assembly, and the output end is connected to the first transmission gear to drive the conveying roller.

[0006] Preferably, a second transmission member is arranged outside the cabin assembly. The second transmission member is composed of a fourth transmission gear and a second transmission wheel. The other end of the transmission roller is fixedly equipped with a first transmission wheel, and the second transmission wheel is connected to the first transmission wheel through a toothed belt so that the transmission roller and the conveying roller rotate synchronously relative to each other.

[0007] Preferably, the cabin assembly includes a housing fixedly installed on the support base, and the top of the housing is communicated with the bottom of the collection box through a feed port; A discharge port is opened at the bottom of the housing.

[0008] Preferably, the conveying assembly includes a conveying groove opening formed on the outside of the conveying roller; When the conveying groove opening is vertical, the conveying groove opening is kept vertical with the feed port.

[0009] Preferably, the compression assembly further includes a first connecting member fixedly installed on the outside of the transmission roller, and an arc-shaped compression plate is fixedly installed on the outside of the first connecting member; The arc-shaped compression plate corresponds to the conveying groove opening. During the rotation of the arc-shaped compression plate and the conveying roller, the arc-shaped compression plate is sequentially engaged in the conveying groove opening, and the arc-shaped compression plate does not contact the inner wall of the conveying groove opening.

[0010] Preferably, a second through groove is formed on the outside of the transmission roller, and first through grooves are formed at both ends of the first through groove; The connecting frame is U-shaped, and the cutting knives are arranged at both ends of the connecting frame; The connecting frame passes through the second through groove, the cutting knives pass through the first through groove and protrude from the arc surface of the arc-shaped compression plate, and the lengths of the second through groove and the first through groove are greater than those of the connecting frame and the cutting knives.

[0011] Preferably, a liquid discharge through groove is formed on the periphery of the conveying roller and between two adjacent conveying groove openings; When the conveying roller and the arc-shaped compression plate rotate synchronously, the arc-shaped compression plate is gradually engaged in the conveying groove opening, and the cutting knife first contacts the conveyed plastic bottle to process its incision.

[0012] Preferably, an arc-shaped groove is formed in the conveying trough opening, a fixed cam rod is fixedly installed on the side of the housing, and the fixed cam rod penetrates into the middle of the conveying roller; A separating elastic member is arranged in the conveying trough opening, a first transmission member is fixedly installed on the inner wall of the separating elastic member, and the first transmission member slides inside the conveying roller; Initially, when the conveying trough opening is vertical, the separating elastic member is in an arched state. The discarded plastic bottle contacts the separating elastic member in the conveying trough opening. The conveying roller rotates to compress the discarded plastic bottle through the arc-shaped compression plate and pushes the separating elastic member to engage it in the arc-shaped groove. As the separating elastic member continues to rotate, one end of the first transmission member is guided outside the fixed cam rod to push the separating elastic member to reset and arch.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, the discarded plastic bottle is placed on the collection box, and the discarded plastic bottle falls onto the conveying assembly. The conveying assembly and the transmission roller are driven by a motor to rotate relatively synchronously. The conveying assembly conveys the discarded plastic bottle, while the transmission roller, the transmission shaft, the connecting frame and the cutting knife rotate synchronously. During the rotation of the transmission roller, the second transmission gear drives the third transmission gear and the transmission wheel disc to rotate. Since the transmission wheel disc is inclined, the second connecting member slides outside the transmission wheel disc. The rotation of the transmission wheel disc causes the second connecting member, the docking member, the transmission shaft, the connecting frame and the cutting knife to move axially. During the conveying of the plastic bottle by the conveying roller, the cutting knife moves axially to cut the plastic bottle, avoiding the phenomenon that the plastic bottle bursts due to being sealed with a bottle cap at the end and being compressed; In the present invention, the discarded plastic bottle falls into the conveying trough opening. The conveying roller and the arc-shaped compression plate rotate synchronously. During the rotation, the cutting knife at one end of the arc-shaped compression plate contacts the discarded plastic bottle in the conveying trough opening. At the same time, the discarded plastic bottle is cut by the reciprocating movement of the cutting knife, and the liquid in the discarded plastic bottle is discharged through the cut. Then, the arc-shaped compression plate gradually engages in the conveying trough opening, and the arc-shaped compression plate compresses the discarded plastic bottle. As the conveying roller continues to rotate, the compressed discarded plastic bottle and the liquid in the bottle are discharged through the discharge port for collection; In the present invention, the discarded plastic bottle in the collection box falls into the conveying trough opening through the feed port and contacts the separating elastic member. As the conveying roller and the arc-shaped compression plate rotate relatively synchronously, the arc-shaped compression plate contacts the discarded plastic bottle and compresses the plastic bottle into the conveying trough opening, causing the separating elastic member to engage in the arc-shaped groove. As the conveying roller continues to rotate, the first transmission member is guided by the fixed cam rod to push the separating elastic member to arch. During this process, the compressed discarded plastic bottle is pushed out of the conveying trough opening by the separating elastic member, avoiding the compressed plastic bottle being stuck in the conveying trough opening.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] As Figures 1 to 10 shown, the present invention provides a waste plastic recycling and treatment device, including a support base 1, and further including: An engine room component 2, and the engine room component 2 is fixedly installed on the support base 1; A collection box 3, the collection box 3 is installed on the top of the engine room assembly 2; A conveying assembly 4, the conveying assembly 4 is arranged at one end inside the engine room assembly 2 and is used for conveying plastic bottles in the collection box 3; A compression assembly 6, the compression assembly 6 is arranged at the other end inside the engine room assembly 2 and is used for compressing the plastic bottles conveyed by the collection box 3; Wherein, the compression assembly 6 includes a driving roller 61 arranged inside the engine room assembly 2, a transmission shaft 613 is movably installed in the middle of the driving roller 61, and a cutting knife 612 is fixedly installed on the outside of the transmission shaft 613 through a connecting frame 611; One end of the driving roller 61 is fixedly installed with a second transmission gear 616, a third transmission gear 617 meshing with the second transmission gear 616 is fixedly installed on the side of the engine room assembly 2, and a transmission wheel disc 618 is fixedly installed on the side of the third transmission gear 617; One end of the transmission shaft 613 is movably provided with a docking member 610, and a second connecting member 619 sliding outside the transmission wheel disc 618 is hinged on the outside of the docking member 610; The plastic bottles in the collection box 3 fall onto the conveying assembly 4 for conveying, and the connecting frame 611, the cutting knife 612 and the conveying assembly 4 rotate synchronously to cut the conveyed plastic bottles; The conveying assembly 4 includes a conveying roller 42 arranged inside the engine room assembly 2, a first transmission gear 49 is fixedly installed at one end of the conveying roller 42, and a motor is fixedly installed outside the engine room assembly 2, and the output end is connected to the first transmission gear 49 for driving the conveying roller 42; A second transmission member 40 is arranged outside the engine room assembly 2, the second transmission member 40 is composed of a fourth transmission gear and a second transmission wheel, a first transmission wheel 62 is fixedly installed at the other end of the driving roller 61, and the second transmission wheel is connected to the first transmission wheel 62 through a toothed belt so that the driving roller 61 and the conveying roller 42 rotate relatively synchronously.

[0018] The discarded plastic bottles are placed on the collection box 3, and the discarded plastic bottles fall onto the fixed cam rod 41. The fixed cam rod 41 is driven by the motor to rotate synchronously with the transmission roller 61. The fixed cam rod 41 conveys the discarded plastic bottles, and then meshes with the first transmission gear 49 through the fourth transmission gear, and the second transmission wheel drives the first transmission wheel 62 and the transmission roller 61 to rotate synchronously through the toothed belt, and the transmission shaft 613, the connecting frame 611 and the cutting knife 612 follow the synchronous rotation. During the rotation of the transmission roller 61, the second transmission gear 616 drives the first transmission wheel 62 and the transmission roller 61 to rotate synchronously. The third transmission gear 617 and the transmission wheel 618 are driven to rotate, and since the transmission wheel 618 is inclined, the second connecting member 619 slides on the outside of the transmission wheel 618, and the transmission wheel 618 rotates through the second connecting member 619, the docking member 610, the transmission shaft 613, the connecting frame 611 and the cutting knife 612 to move axially, and the conveying roller 42 performs incision processing on the plastic bottles through the axial movement of the cutting knife 612 during the conveying process of the plastic bottles, so as to avoid the plastic bottles from bursting due to the pressure caused by the bottle caps at the ends being in a sealed state.

[0019] like Figure 2 and Figure 5 As shown, the cabin assembly 2 includes a shell 21 fixedly mounted on the support base 1, and the top of the shell 21 is connected to the bottom of the collection box 3 through the feed port 22; A discharge port 23 is provided at the bottom of the housing 21; The conveying assembly 4 includes a conveying notch 44 opened outside the conveying roller 42; When the conveying slot 44 is in a vertical position, the conveying slot 44 and the feed port 22 remain vertical; The compression assembly 6 further includes a first connecting member 63 fixedly mounted on the outside of the driving roller 61, and an arc-shaped compression plate 64 is fixedly mounted on the outside of the first connecting member 63; The arc compression plate 64 keeps corresponding to the conveying slot 44 . During the rotation of the arc compression plate 64 and the conveying roller 42 , the arc compression plate 64 is sequentially engaged in the conveying slot 44 , and the arc compression plate 64 does not contact the inner wall of the conveying slot 44 .

[0020] The conveying roller 42 is driven by a motor to rotate. During the rotation, the conveying slot 44 and the feed port 22 remain vertical. The discarded plastic bottles in the collection box 3 fall into the conveying slot 44 through the feed port 22. The conveying roller 42 cooperates with the inner wall of the shell 21 to convey the plastic bottles, and the driving roller 61, the first connecting member 63 and the arc-shaped compression plate 64 rotate synchronously with the conveying roller 42, and gradually contact the discarded plastic bottles in the conveying slot 44 through the arc-shaped compression plate 64. As the arc-shaped compression plate 64 gradually engages in the conveying slot 44, the discarded plastic bottles are compressed by the arc-shaped compression plate 64, so that the compressed plastic bottles are located between the arc-shaped compression plate 64 and the conveying slot 44.

[0021] likeFigures 6 - 8 As shown, a second through groove 615 is provided on the outside of the driving roller 61, and first through grooves 614 are provided at both ends of the first through groove 614; The connecting frame 611 is U-shaped, and the cutting knives 612 are arranged at both ends of the connecting frame 611; The connecting frame 611 passes through the second through groove 615, and the cutting knives 612 pass through the first through grooves 614 and protrude from the arc surface of the arc-shaped compression plate 64. The lengths of the second through groove 615 and the first through grooves 614 are greater than those of the connecting frame 611 and the cutting knives 612; A liquid discharge through groove 43 is provided on the periphery of the conveying roller 42 and between two adjacent conveying slots 44; When the conveying roller 42 and the arc-shaped compression plate 64 rotate synchronously, the arc-shaped compression plate 64 gradually engages with the conveying slot 44, and the cutting knife 612 first contacts the conveyed plastic bottle for notch treatment.

[0022] The waste plastic bottles fall into the conveying slot 44. Through the synchronous rotation of the conveying roller 42 and the arc-shaped compression plate 64, during the rotation process, the cutting knife 612 at one end of the arc-shaped compression plate 64 contacts the waste plastic bottles in the conveying slot 44. At the same time, the waste plastic bottles are notched through the reciprocating movement of the cutting knife 612, and the liquid in the waste plastic bottles is discharged through the notch. Then, the arc-shaped compression plate 64 gradually engages with the conveying slot 44, so as to compress the waste plastic bottles through the arc-shaped compression plate 64. As the conveying roller 42 continues to rotate, the compressed waste plastic bottles and the liquid in the bottles are discharged through the discharge port 23. At the same time, a conveyor belt can be provided at the bottom of the housing 21 to collect the compressed plastic bottles.

[0023] As Figure 2 shown in Figure 5 connection with An arc-shaped groove 46 is provided on the conveying slot 44, and a fixed cam rod 41 is fixedly installed on the side of the housing 21. The fixed cam rod 41 penetrates into the middle of the conveying roller 42; A separating elastic member 47 is arranged in the conveying slot 44. A first transmission member 45 is fixedly installed on the inner wall of the separating elastic member 47, and the first transmission member 45 slides inside the conveying roller 42;

[0024] When the initial state conveying trough opening 44 is vertical and remains connected to the feed port 22, the separating elastic member 47 is in an arched state. The waste plastic bottles in the collection box 3 fall into the conveying trough opening 44 through the feed port 22 and contact the separating elastic member 47. As the conveying roller 42 and the arc-shaped compression plate 64 rotate relatively synchronously, the arc-shaped compression plate 64 contacts the waste plastic bottles and compresses the plastic bottles into the conveying trough opening 44, causing the separating elastic member 47 to engage in the arc-shaped groove 46. As the conveying roller 42 continues to rotate, the first transmission member 45 is guided by the fixed cam rod 41 to push the separating elastic member 47 to arch. During this process, the compressed waste plastic bottles are pushed out of the conveying trough opening 44 through the separating elastic member 47, preventing the compressed plastic bottles from getting stuck in the conveying trough opening 44, and the discharged plastic bottles are discharged through the discharge port 23.

[0025] The working principle and usage process of the present invention: Place the waste plastic bottles on the collection box 3, drive the conveying roller 42 to rotate through the motor. During the rotation process, the conveying trough opening 44 and the feed port 22 remain vertical. The waste plastic bottles in the collection box 3 fall into the conveying trough opening 44 through the feed port 22. The conveying roller 42 and the inner wall of the housing 21 cooperate to convey the plastic bottles. The driving roller 61, the first connecting member 63 and the arc-shaped compression plate 64 rotate relatively synchronously with the conveying roller 42. The arc-shaped compression plate 64 gradually contacts the waste plastic bottles in the conveying trough opening 44. Then, through the engagement of the fourth transmission gear and the first transmission gear 49, and the second transmission wheel drives the first transmission wheel 62 and the driving roller 61 to rotate synchronously through the toothed belt. The transmission shaft 613, the connecting frame 611 and the cutting knife 612 rotate synchronously. During the rotation of the driving roller 61, the second transmission gear 616 drives the third transmission gear 617 and the transmission wheel disc 618 to rotate. Since the transmission wheel disc 618 is inclined, the second connecting member 619 slides outside the transmission wheel disc 618. The rotation of the transmission wheel disc 618 causes the second connecting member 619, the docking member 610, the transmission shaft 613, the connecting frame 611 and the cutting knife 612 to move axially. During the conveying of the plastic bottles by the conveying roller 42, the cutting knife 612 moves axially to cut the plastic bottles, preventing the plastic bottles from bursting under pressure due to the end being sealed with a bottle cap. The driving roller 61, the first connecting member 63 and the arc-shaped compression plate 64 rotate relatively synchronously with the conveying roller 42. The arc-shaped compression plate 64 gradually contacts the waste plastic bottles in the conveying trough opening 44. As the arc-shaped compression plate 64 gradually engages in the conveying trough opening 44, the waste plastic bottles are compressed by the arc-shaped compression plate 64, so that the compressed plastic bottles are located between the arc-shaped compression plate 64 and the conveying trough opening 44. As the conveying roller 42 continues to rotate, the compressed waste plastic bottles and the liquid in the bottles are discharged through the discharge port 23. At the same time, a conveyor belt can be provided at the bottom of the housing 21 to collect the compressed plastic bottles. When the initial state conveying trough opening 44 is in the vertical position and remains connected to the feeding port 22, the separating elastic member 47 is in an arched state. The discarded plastic bottles in the collection box 3 fall into the conveying trough opening 44 through the feeding port 22 and contact the separating elastic member 47. As the conveying roller 42 and the arc-shaped compression plate 64 rotate synchronously relative to each other, the arc-shaped compression plate 64 contacts the discarded plastic bottles and compresses the plastic bottles into the conveying trough opening 44, causing the separating elastic member 47 to be engaged in the arc-shaped groove 46. As the conveying roller 42 continues to rotate, the first transmission member 45 is guided by the fixed cam rod 41 to push the separating elastic member 47 to arch. During this process, the compressed discarded plastic bottles are pushed out of the conveying trough opening 44 through the separating elastic member 47, preventing the compressed plastic bottles from getting stuck in the conveying trough opening 44. The discharged plastic bottles are discharged through the discharge opening 23.
