DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and examples.

[0026] In one embodiment, as shown in Figures 1-4 A plastic bottle recycling machine, comprising a machine body 1 and a base 2 fixed at the lower end of the machine body 1, the front end of the machine body 1 is provided with a bottle inlet 11, and the inside of the machine body 1 is provided with a processing cavity 12, a transport cavity 13, a bottle body feeding cavity 15, a bottle body crushing cavity 16, a bottle cap feeding cavity 17 and a bottle cap crushing cavity 18, the bottle inlet 11 is connected with the inside of the processing cavity 12, the processing cavity 12 is provided with a segmentation structure 3 for segmenting plastic bottles, the processing cavity 12 is connected with the transport cavity 13, the transport cavity 13 is provided with a transport structure 4 for transporting and separating bottle bodies and bottle caps, the end of the transport cavity 13 away from the processing cavity 12 is connected with the bottle body feeding cavity 15, the lower end of the bottle body feeding cavity 15 is provided with the bottle body crushing cavity 16, and the inside of the bottle body crushing cavity 16 is provided with a bottle body crushing structure 6; the bottle cap feeding cavity 17 is provided at the lower end of the transport cavity 13, the bottle cap crushing cavity 18 is located at the lower end of the bottle cap feeding cavity 17, the inside of the bottle cap feeding cavity 17 is provided with a cap transport structure 5 for transporting the bottle cap to the inside of the bottle cap crushing cavity 18, and the inside of the bottle cap crushing cavity 18 is provided with a bottle cap crushing structure 8; the base 2 is provided with a bottle body collecting cavity 21 and a bottle cap collecting cavity 23 at the front end, the bottle body collecting cavity 21 is connected with the bottle body crushing cavity 16, the bottle cap collecting cavity 23 is connected with the bottle cap crushing cavity 18, and the bottle body collecting cavity 21 and the bottle cap collecting cavity 23 are respectively provided with a bottle body collecting drawer 22 and a bottle cap collecting drawer 24.

[0027] In the embodiment, the user puts the plastic bottle into the front bottle inlet 11, and the bottle body enters the processing cavity 12. Then the bottle body is divided by the division structure 3. After the division, the bottle body enters the conveying cavity 13. The conveying structure 4 conveys the bottle body. Since the bottle body is divided, the cap and the bottle body are not in a connected relationship. During the conveying of the bottle body and the cap, the cap falls into the cap inlet cavity 17 from the gap of the conveying structure 4. Then the cap is conveyed to the cap crushing cavity 18 by the cap conveying structure 5 in the cap inlet cavity 17. The cap crushing structure 8 in the cap crushing cavity 18 crushes the cap. The crushed cap enters the cap collection drawer 24.

[0028] The bottle body enters the bottle body inlet cavity 15 and finally enters the bottle body crushing cavity 16. The bottle body crushing structure 6 in the bottle body crushing cavity 16 crushes the bottle body. The crushed bottle body enters the bottle body collection drawer 22.

[0029] In an optional embodiment, the division structure 3 includes a fixed block 33 which slides with the inner wall of the processing cavity 12. One end of the fixed block 33 extends to the outer wall of the machine body 1 and is fixedly connected with a fixed plate 32. The fixed plate 32 is fixedly connected with the telescopic end of a push rod 31. The push rod 31 is installed on the machine body 1. A plurality of division knives 35 are equidistantly fixed at the connection position of the processing cavity 12 and the conveying cavity 13.

[0030] It should be noted that when the fixed block 33 slides, the bottle body is pushed into the gap between the division knives 35, realizing longitudinal division, so that the bottle body is divided into multiple parts, thereby making the cap and the bottle body not in a connected relationship, which is beneficial to the subsequent separation of the cap and the bottle body.

[0031] In an optional embodiment, one end of the fixed block 33 close to the division knife 35 is fixedly connected with a plurality of spacing blocks 34. Each spacing block 34 is located between two division knives 35.

[0032] It should be noted that the spacing blocks 34 at the front end of the fixed block 33 are staggered with the division knives 35, which prevents the bottle body from sliding during cutting and improves the cutting stability.

[0033] In an optional embodiment, the conveying structure 4 includes a plurality of conveying rollers 42 which are rotatably installed in the conveying cavity 13. The conveying rollers 42 are equidistantly spaced. One end of each conveying roller 42 is fixedly connected with a synchronous gear one 43. Two synchronous gears one 43 are drivingly connected through a toothed belt one 44. One end of one of the conveying rollers 42 away from the synchronous gear one 43 is fixedly connected with a gear one 41. The gear one 41 is connected with the cap conveying structure 5 in the cap inlet cavity 17.

[0034] It should be noted that the transmission connection of the synchronous gear 43 and the toothed belt 44 enables the synchronous rotation of all the conveying rollers 42, ensuring the coordination and stability of the conveying. One of the conveying rollers 42 is connected to the cover conveying structure 5 through the gear 41, so that the movement of the cover conveying structure 5 can be transmitted to the conveying roller 42, realizing the rotation of the conveying roller 42, and then completing the conveying function, and this connection mode can realize the power transmission and cooperation between the conveying structure and the cover conveying structure.

[0035] The cut bottle body enters the conveying cavity 13 and is conveyed to the bottle body feeding cavity 15 by the equidistantly arranged conveying rollers 42.

[0036] The cap falls into the lower cap feeding cavity 17 from the gap of the conveying roller 42 due to its small size, realizing the automatic separation of the bottle body and the cap.

[0037] In an optional embodiment, the outer wall of the conveying roller 42 is provided with anti-skid lines.

[0038] It should be noted that the anti-skid lines provided on the outer wall of the conveying roller 42 mainly aim to enhance the friction between the conveying roller 42 and the conveyed articles.

[0039] In an optional embodiment, the cover conveying structure 5 comprises a transmission roller I 52 and a transmission roller II 54 rotatably installed inside the cap feeding cavity 17, the outer wall of the transmission roller I 52 and the transmission roller II 54 is sleeved with a conveying belt 53, one end of the transmission roller I 52 is fixedly connected with the output end of a motor I 51, one end of the transmission roller II 54 is fixedly connected with a gear II 55, and the gear II 55 is meshingly connected with the gear I 41.

[0040] It should be noted that the meshing connection of the gear I 41 and the gear II 55 between the cover conveying structure 5 and the conveying structure 4 enables the cover conveying structure 5 to closely cooperate with the conveying structure 4, realizing the seamless connection of the cap from feeding to conveying, and improving the coherence and efficiency of the entire production process.

[0041] In an optional embodiment, the bottle body crushing structure 6 comprises two crushing rollers I 63 rotatably installed inside the bottle body crushing cavity 16, one end of each of the two crushing rollers I 63 is fixedly installed with a gear III 64, the two gear IIIs 64 are meshed, one end of one of the crushing rollers I 63 away from the gear III 64 is fixedly connected with a synchronous gear II 62, the synchronous gear II 62 is fixedly connected with the output end of a motor II 61, and the synchronous gear II 62 is connected with the cap crushing structure 8 located inside the cap crushing cavity 18 through a toothed belt II 7.

[0042] It is to be noted that, in the bottle body crushing structure 6, one of the crushing rollers 63 is fixed to the synchronous gear 62 at the end away from the gear 64, so the rotation of the synchronous gear 62 drives the rotation of the crushing roller 63. Since the two crushing rollers 63 are fixed with gears 64 that mesh with each other, according to the gear transmission principle, when one gear rotates, the other gear meshes with it will rotate in the opposite direction, so the two crushing rollers 63 will rotate in opposite directions, thereby effectively crushing the bottle body placed in the bottle body crushing cavity 16.

[0043] In an alternative embodiment, the bottle cap crushing structure 8 includes a synchronous gear 81 mounted on the machine body 1, and two crushing rollers 82 rotatably mounted in the bottle cap crushing cavity 18, the synchronous gear 81 is in transmission connection with the synchronous gear 62 through the toothed belt 7, the synchronous gear 81 is fixedly connected with one of the crushing rollers 82, and the two crushing rollers 82 are fixed with gears 83 at the ends away from the synchronous gear 81, and the two gears 83 are meshed with each other.

[0044] It is to be noted that the flexible transmission of the toothed belt 7 enables the synchronous gear 81 to obtain power synchronously and stably, thereby driving the rotation of the crushing roller 82 fixedly connected therewith. The meshing gears 83 at the ends of the two crushing rollers 82 away from the synchronous gear 81 further realize the internal transmission and distribution of power, so that the other crushing roller 82 rotates in the opposite direction, ensuring that the two crushing rollers 82 can efficiently crush the bottle cap in opposite directions.

[0045] In an alternative embodiment, the limiting inclined blocks 14 are symmetrically fixed at both ends of the inner wall of the processing cavity 12 and the conveying cavity 13.

[0046] It is to be noted that the limiting inclined blocks 14 ensure that the bottle body can accurately receive the processing operation in the processing cavity 12 without position deviation affecting the processing effect

[0047] The above embodiment discloses a plastic bottle recycling machine, in which a user puts a plastic bottle into the front bottle inlet 11, the bottle body enters the processing cavity 12, the limiting inclined blocks 14 guide the axial alignment of the bottle body, ensuring the subsequent cutting accuracy, the driving rod 31 of the cutting structure 3 is started, driving the fixed block 33 to slide along the inner wall of the processing cavity, and the spacer block 34 and the cutting knife 35 form a dynamic cutting system: the fixed block 33 slides to push the bottle body into the cutting knife 35, realizing the longitudinal cutting of the bottle body, and dividing the bottle body into a bottle body and a bottle cap.

[0048] The cut bottle body enters the conveying cavity 13 and is conveyed to the bottle body inlet cavity 15 by the equidistantly arranged conveying rollers 42.

[0049] The bottle cap falls into the bottle cap feeding cavity 17 below from the gap of the conveying roller 42, realizing the automatic separation of the bottle body and the bottle cap.

[0050] The conveying roller one 52 and the conveying roller two 54 in the bottle cap feeding cavity 17 convey the bottle cap to the bottle cap crushing cavity 18 through the conveying belt 53. The crushing roller two 82 rotates at high speed under the drive of the synchronous gear three 81 and the gear four 83, crushing the bottle cap. The crushed bottle cap particles fall into the bottle cap collection drawer 24, completing the recycling.

[0051] The bottle body enters the bottle body crushing cavity 16 through the bottle body feeding cavity 15. The crushing roller one 63 rotates under the drive of the motor two 61 and the synchronous gear two 62, realizing the bidirectional crushing through the gear three 64 engagement, ensuring the sufficient refinement of the bottle body. The crushed bottle body particles fall into the bottle body collection drawer 22, completing the recycling.

[0052] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
