[0001] The application belongs to the technical field of plastic recycling, and specifically relates to a waste plastic recycling treatment equipment. BACKGROUND

[0002] Waste plastics refer to plastic products discarded because of losing original use value, including packaging materials (such as plastic bags, plastic bottles), electronic product housings, construction waste, agricultural films and the like, and it should be particularly pointed out that the degradation of plastics is not complete mineralization, but is gradually cracked into microplastics (<5mm) or even nanometer plastics (<100nm) through photo-oxidation, mechanical wear and the like, and in this process, harmful substances such as phthalate and bisphenol A are released, which poses multiple threats to the ecological system and human health. At present, in order to facilitate transportation, plastic bottles are usually collected and compressed into blocks to reduce the volume of plastic bottles, but when the plastic bottles are compressed, part of the plastic bottles is in a sealed state due to the bottle cap at the end, the gas in the plastic bottle is difficult to discharge, which leads to the difficulty in compression of the plastic bottle, and the sealed plastic bottle will burst under pressure, which produces high-speed flying fragments and has a safety hazard, and therefore the present application provides a waste plastic recycling treatment equipment.

[0018] When the conveying slot is vertical, the conveying slot and the feeding port are kept vertical.

[0019] Preferably, the compression assembly further comprises a first connecting piece fixedly arranged on the outside of the transmission roller, and the outside of the first connecting piece is fixedly provided with an arc-shaped compression plate.

[0020] The arc-shaped compression plate corresponds to the conveying slot, the arc-shaped compression plate is sequentially clamped in the conveying slot in the rotation process of the arc-shaped compression plate and the conveying roller, and the arc-shaped compression plate does not contact the inner wall of the conveying slot.

[0021] Preferably, the outside of the transmission roller is provided with a second through groove, and the two ends of the first through groove are provided with a first through groove.

[0028] Initially, when the conveying slot is vertical, the separation elastic member is in an arched state. The discarded plastic bottles contact the separation elastic member in the conveying slot. The conveying roller rotates to compress the discarded plastic bottles through the arc-shaped compression plate, and pushes the separation elastic member to engage in the arc-shaped groove. As the separation elastic member continues to rotate, one end of the first transmission member pushes the separation elastic member to return to the arched state under the guidance of the outside of the fixed cam rod.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] The present invention places discarded plastic bottles on a collection box, and the discarded plastic bottles fall onto a conveying assembly. The conveying assembly is driven by a motor to rotate synchronously with a transmission roller, and the conveying assembly conveys the discarded plastic bottles. The transmission roller, the transmission shaft, the connecting frame and the cutting knife rotate synchronously. During the rotation of the transmission roller, the third transmission gear and the transmission wheel disc are driven to rotate by the second transmission gear. Since the transmission wheel disc is inclined, the second connecting member slides outside the transmission wheel disc. The rotation of the transmission wheel disc moves axially through the second connecting member, the docking member, the transmission shaft, the connecting frame and the cutting knife. During the conveying roller conveying the plastic bottles, the plastic bottles are cut by the axial movement of the cutting knife, thereby preventing the plastic bottles from bursting due to pressure caused by being in a sealed state with bottle caps at the ends.

[0031] The present invention allows discarded plastic bottles to fall into a conveying slot, and the conveying roller and the arc-shaped compression plate rotate synchronously. During the rotation, a cutting knife at one end of the arc-shaped compression plate contacts the discarded plastic bottles in the conveying slot, and the cutting knife reciprocates to cut the discarded plastic bottles. The liquid in the discarded plastic bottles is discharged through the cut, and then gradually engages with the conveying slot through the arc-shaped compression plate. The arc-shaped compression plate compresses the discarded plastic bottles. As the conveying roller continues to rotate, the compressed discarded plastic bottles and the liquid in the bottles are discharged and collected through the discharge port.

[0032] The present invention allows discarded plastic bottles in a collection box to fall into a conveying slot through a feed port and come into contact with a separation elastic member. As the conveying roller and the arc-shaped compression plate rotate synchronously relative to each other, the arc-shaped compression plate comes into contact with the discarded plastic bottles, compressing the plastic bottles into the conveying slot, causing the separation elastic member to engage in the arc-shaped groove. As the conveying roller continues to rotate, the first transmission member, under the guidance of a fixed cam rod, pushes the separation elastic member to arch. During this process, the compressed discarded plastic bottles are pushed into the conveying slot by the separation elastic member, thereby preventing the compressed plastic bottles from being stuck in the conveying slot.

[0057] As shown in Figure 2 As shown in Figure 5 The top of the shell 21 is communicated with the bottom of the collecting box 3 through a feeding port 22;

[0058] The bottom of the shell 21 is provided with a discharging port 23;

[0059] The conveying assembly 4 comprises a conveying slot 44 arranged on the outside of the conveying roller 42;

[0060] When the conveying slot 44 is in a vertical position, the conveying slot 44 and the feed port 22 remain vertical;

[0061] The compression assembly 6 further includes a first connecting member 63 fixedly mounted on the outside of the transmission roller 61, and an arc-shaped compression plate 64 is fixedly mounted on the outside of the first connecting member 63;

[0062] The arc compression plate 64 corresponds 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 .

[0063] The conveying roller 42 is driven to rotate by a motor. 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 transmission roller 61, the first connecting member 63 and the arc-shaped compression plate 64 rotate synchronously with the conveying roller 42. The arc-shaped compression plate 64 gradually contacts the discarded plastic bottles in the conveying slot 44. As the arc-shaped compression plate 64 gradually engages with 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.

[0064] like Figure 6-Figure 8 As shown, a second through slot 615 is formed on the outside of the transmission roller 61 , and first through slots 614 are formed at both ends of the first through slot 614 ;

[0065] The connecting frame 611 is U-shaped, and the cutting blades 612 are provided at both ends of the connecting frame 611;

[0066] The connecting frame 611 passes through the second through slot 615 , and the cutting blade 612 passes through the first through slot 614 and protrudes from the arc surface of the arc-shaped compression plate 64 . The lengths of the second through slot 615 and the first through slot 614 are greater than those of the connecting frame 611 and the cutting blade 612 .

[0067] A drainage groove 43 is formed on the periphery of the conveying roller 42 and between two adjacent conveying slots 44;

[0068] When the conveying roller 42 and the arc-shaped compression plate 64 rotate synchronously, the arc-shaped compression plate 64 gradually engages in the conveying slot 44, and the cutting blade 612 first contacts the conveyed plastic bottle to cut the bottle.

[0069] The discarded plastic bottles fall into the conveying slot 44, and the conveying roller 42 and the arc-shaped compression plate 64 rotate synchronously. During the rotation, the cutting knife 612 at one end of the arc-shaped compression plate 64 contacts the discarded plastic bottles in the conveying slot 44. At the same time, the discarded plastic bottles are incised by the reciprocating motion of the cutting knife 612, and the liquid in the discarded plastic bottles is discharged through the incision, and then gradually engaged with the conveying slot 44 through the arc-shaped compression plate 64, so that the discarded plastic bottles are compressed by the arc-shaped compression plate 64. As the conveying roller 42 continues to rotate, the compressed discarded plastic bottles and the liquid in the bottles are discharged through the discharge port 23. At the same time, a conveyor belt can be set at the bottom of the shell 21 to collect the compressed plastic bottles.

[0070] like Figure 2 and Figure 5 As shown, an arc-shaped groove 46 is provided on the conveying notch 44, and a fixed cam rod 41 is fixedly mounted on the side of the housing 21, and the fixed cam rod 41 penetrates the middle of the conveying roller 42;

[0071] A separation elastic member 47 is provided in the conveying slot 44 , and a first transmission member 45 is fixedly mounted on the inner wall of the separation elastic member 47 , and the first transmission member 45 slides inside the conveying roller 42 ;

[0072] When the initial conveying slot 44 is vertical, the separation elastic member 47 is in an arched state. The discarded plastic bottles come into contact with the separation elastic member 47 in the conveying slot 44. The conveying roller 42 rotates to compress the discarded plastic bottles through the arc-shaped compression plate 64, and pushes the separation elastic member 47 to engage in the arc-shaped groove 46. As the separation elastic member 47 continues to rotate, one end of the first transmission member 45 pushes the separation elastic member 47 to return to its arched state under the guidance of the outside of the fixed cam rod 41.

[0073] In the initial state, when the conveying slot 44 is vertically connected to the feed port 22, the separation elastic member 47 is in an arched state, and the discarded plastic bottles in the collection box 3 fall into the conveying slot 44 through the feed port 22 and contact the separation 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, compressing the plastic bottles into the conveying slot 44, so that the separation elastic member 47 is engaged in the arc-shaped groove 46. As the conveying roller 42 continues to rotate, the first transmission member 45 pushes the separation elastic member 47 to arch under the guidance of the fixed cam rod 41. In this process, the compressed discarded plastic bottles are pushed out of the conveying slot 44 by the separation elastic member 47 to prevent the compressed plastic bottles from being stuck in the conveying slot 44. The discharged plastic bottles are discharged through the discharge port 23.

[0074] The working principle and use process of the present invention:

[0075] The discarded plastic bottles are placed on the collection box 3, and the conveying roller 42 is driven by the motor to rotate. During the rotation, the conveying slot 44 and the feed port 22 remain vertical, and 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 transmission roller 61, the first connecting member 63 and the arc-shaped compression plate 64 rotate synchronously with the conveying roller 42, gradually contacting the discarded plastic bottles in the conveying slot 44 through the arc-shaped compression plate 64, and then meshing 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 61 3. The connecting frame 611 and the cutting blade 612 rotate synchronously. During the rotation of the transmission roller 61, the third transmission gear 617 and the transmission wheel 618 are driven to rotate via the second transmission gear 616. Since the transmission wheel 618 is inclined, the second connecting member 619 slides outside the transmission wheel 618. 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 blade 612 to move axially. During the transportation of the plastic bottles by the conveying roller 42, the axial movement of the cutting blade 612 is used to cut the plastic bottles, thereby preventing the plastic bottles from bursting due to pressure caused by the bottle caps at the ends being in a sealed state.

[0076] The driving roller 61, the first connecting member 63 and the arc-shaped compression plate 64 rotate synchronously with the conveying roller 42, and the arc-shaped compression plate 64 gradually contacts the discarded plastic bottles in the conveying slot 44. As the arc-shaped compression plate 64 gradually engages with 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. As the conveying roller 42 continues to rotate, the compressed discarded 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.

[0077] In the initial state, when the conveying slot 44 is vertically connected to the feed port 22, the separation elastic member 47 is in an arched state, and the discarded plastic bottles in the collection box 3 fall into the conveying slot 44 through the feed port 22 and contact the separation 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, compressing the plastic bottles into the conveying slot 44, so that the separation elastic member 47 is engaged in the arc-shaped groove 46. As the conveying roller 42 continues to rotate, the first transmission member 45 pushes the separation elastic member 47 to arch under the guidance of the fixed cam rod 41. In this process, the compressed discarded plastic bottles are pushed out of the conveying slot 44 by the separation elastic member 47 to prevent the compressed plastic bottles from being stuck in the conveying slot 44. The discharged plastic bottles are discharged through the discharge port 23.

As the separation elastic member (47) continues to rotate, one end of the first transmission member (45) pushes the separation elastic member (47) to return to the arched state under the guidance of the outside of the fixed cam rod (41).
