Description

Technical Field

[0001] This utility model relates to the field of fabric recycling technology, and in particular to a cutting mechanism for fabric recycling and granulation. Background Technology

[0002] Nonwoven fabric is a material made from polyester as raw material. It is produced through melt spinning, piling and weaving, hot pressing and bonding, and finally drying and shaping into a cotton-like fabric. It features moisture resistance, breathability, flexibility, lightweight, flame retardancy, non-toxicity, odorlessness, low price, and recyclability. It can be used in various industries, such as sound insulation, heat insulation, electric heaters, masks, clothing, medical applications, and filling materials. In nonwoven fabric production, to obtain nonwoven fabric of specific sizes, the rolls need to be cut, generating waste trimming rolls. These waste trimming rolls cannot be reused; to avoid waste, they are usually recycled.

[0003] In existing technologies, fabric recycling typically involves processes such as melting, extrusion, cooling, cutting, and granulation. However, existing cutting mechanisms lack sorting capabilities, resulting in uneven cutting and inconsistent particle sizes. This necessitates screening and can lead to the need for further cutting of waste materials, thereby reducing work efficiency. Therefore, there is room for improvement. Utility Model Content

[0004] This invention provides a cutting mechanism for fabric recycling and granulation to solve the problems mentioned in the background art.

[0005] To address the aforementioned problems, this utility model provides a cutting mechanism for fabric recycling and granulation, comprising a mounting plate, a traction mechanism, a guiding mechanism, and a cutting mechanism. The mounting plate has a movable groove on its front side and a guide plate on its rear side. The traction mechanism consists of a driving roller, a driven roller, and a motor. The driving roller is rotatably mounted on the mounting plate and located above the movable groove. The driven roller is rotatably mounted within the movable groove. The motor is located on one side of the mounting plate and connected to one end of the driving roller. A driving gear is mounted on the end of the driving roller away from the motor. A driven gear meshing with the driving gear is mounted on one end of the driven roller, which rotatably passes through the movable groove. The guiding mechanism consists of two symmetrical guide boxes symmetrically positioned on both sides of the movable groove. Each guide box comprises a lower guide plate and an upper guide plate. The system comprises a lower guide plate fixed to a mounting plate, an upper guide plate connected to the lower guide plate by bolts, and several semi-circular through holes spaced equally between the upper and lower guide plates, with the through holes aligned with each other. A cutting mechanism is located on the rear side of the guide mechanism on the mounting plate. The cutting mechanism consists of a protective cover, a rotating shaft, and a cutting blade. The protective cover is mounted on the guide plate and communicates with the guide box on its front side. The rotating shaft is rotatably disposed within the protective cover and contains a cross-shaped blade holder. The cutting blade is vertically mounted within the cross-shaped blade holder. One end of the rotating shaft rotatably passes through the protective cover and is fitted with a first pulley. A second pulley is mounted on the outside of the drive gear, and the second pulley is connected to the first pulley by a belt.

[0006] Preferably, the outer surfaces of the driving roller and the driven roller are fitted with rubber sleeves.

[0007] Preferably, the aligned through holes in the upper and lower guide plates are located between the driving roller and the driven roller.

[0008] Preferably, the lower guide plate has positioning posts fixed at both ends, and the upper guide plate has positioning grooves at both ends that match the positioning posts.

[0009] The beneficial effects of adopting the above technical solutions are: The guide box formed by the upper and lower guide plates in the guiding mechanism, along with the through holes, can disperse and align the formed fiber strips, making it easier for the active and driven rollers in the traction mechanism to drive the fiber strips to move. Then, the fiber strips are guided into the protective cover through another guide box, allowing them to enter the protective cover in an orderly manner. The rotation of the rotating shaft in the cutting mechanism drives the cutting blade to cut the fiber strips into pellets. Because the fiber strips enter in an orderly manner, the uniformity of the cutting is ensured, thus improving work efficiency. Attached Figure Description

[0019] like Figure 1-5In this embodiment, a cutting mechanism for fabric recycling and granulation includes a mounting plate 1, a traction mechanism 2, a guiding mechanism 3, and a cutting mechanism 4. The mounting plate 1 has a movable groove 11 on its front side and a guide plate 12 on its rear side. The traction mechanism 2 consists of a driving roller 21, a driven roller 22, and a motor 23. The driving roller 21 is rotatably mounted on the mounting plate 1 and located above the movable groove 11. The driven roller 22 is rotatably mounted within the movable groove 11. The motor 23 is located on one side of the mounting plate 1 and connected to one end of the driving roller 21. A driving gear 211 is mounted on the end of the driving roller 21 away from the motor 23. A driven gear 221 meshing with the driving gear 211 is mounted on one end of the driven roller 22, which rotatably passes through the movable groove 11. The guiding mechanism 3 consists of two symmetrical guide boxes 31, symmetrically arranged on both sides of the movable groove 11. Each guide box 31 consists of a lower guide plate 32 and an upper guide plate 33. The lower guide plate 32 is fixed on the mounting plate 1. The upper guide plate 33 is bolted to the lower guide plate 32. The upper guide plate 33 and the lower guide plate 32 are provided with a plurality of semi-circular through holes 34 at equal intervals, and the through holes in the upper guide plate 33 and the lower guide plate 32 are aligned with each other. The cutting mechanism 4 is located on the rear side of the upper guide mechanism 3 on the mounting plate 1. The cutting mechanism 4 is composed of a protective cover 41, a rotating shaft 42, and a cutting blade 43. The protective cover 41 is installed on the guide plate 12 and its front side communicates with the guide box 31. The rotating shaft 42 is rotatably located inside the protective cover 41, and a cross-shaped blade holder 44 is provided in the rotating shaft 42. The cutting blade 43 is vertically installed in the cross-shaped blade holder 44. One end of the rotating shaft 42 rotates through the protective cover 41, and a first pulley 421 is installed at the end. A second pulley 212 is installed on the outside of the drive gear 211, and the second pulley 212 and the first pulley 421 are connected by a belt.

[0020] With the above technical solution, the formed fiber strips are dispersed into the through holes 34 in the lower guide plate 32 during use, and then the upper guide plate 33 is fastened to the lower guide plate 32. The fiber strips are then passed between the active roller 21 and the driven roller 22, and then through another guide box 31. At this time, the motor 23 in the traction mechanism 2 drives the active roller 21 to rotate. At the same time, the active gear 211 and the driven gear 221 drive the driven roller 22 to rotate synchronously, thereby traction of the fiber strips, so that the fiber strips are orderly dispersed into the protective cover 41. The rotation of the synchronous active gear 211 drives the first pulley 421 through the second pulley 212, causing the rotating shaft 42 in the cutting mechanism 4 to rotate. This drives the cutting blade 43 to rotate through the cross-shaped blade holder 44, cutting the incoming fiber strips into granules. The granulated fiber particles are then discharged through the guide plate 12.

[0021] Preferably, the outer surfaces of the driving roller 21 and the driven roller 22 are fitted with rubber sleeves 24.

[0022] Through the above technical solution, the rubber sleeve 24 is provided to increase the friction between the active roller 21 and the driven roller 22, thereby ensuring the traction force of the fiber strip.

[0023] Preferably, the through holes 34 aligned in the upper guide plate 33 and the lower guide plate 32 are located between the driving roller 21 and the driven roller 22.

[0024] With the above technical solution, the through hole 34 in the upper guide plate 33 and the lower guide plate 32 is located between the driving roller 21 and the driven roller 22, thereby ensuring the stability of traction.

[0025] Preferably, the lower guide plate 32 has positioning posts 321 fixed at both ends, and the upper guide plate 33 has positioning grooves 331 at both ends that match the positioning posts 321.

[0026] Through the above technical solution, the positioning post 321 of the lower guide plate 32, in conjunction with the positioning groove 331 in the upper guide plate 33, can quickly position the upper guide plate 33 and the lower guide plate 32, so that the through hole 34 can be quickly aligned.
