Description

Technical Field

[0001] This utility model relates to the field of polypropylene resin, specifically to a high-efficiency spiral crushing roller assembly device for polypropylene resin. Background Technology

[0002] Polypropylene resin, as an important thermoplastic, is widely used in packaging, automotive, electronics, construction and other fields. However, during the production, processing or recycling of polypropylene resin, raw materials in the form of lumps, flakes or agglomerates often occur. If these materials are directly fed into subsequent processing equipment (such as extruders and injection molding machines), the following problems may occur: the material tends to accumulate above the crushing roller, resulting in low crushing efficiency, and single shearing or extrusion methods are difficult to handle high-toughness materials. To address this, we propose a high-efficiency spiral crushing roller assembly device for polypropylene resin. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a high-efficiency spiral crushing roller assembly for polypropylene resin, which solves the aforementioned problems.

A second mounting plate is fixed on the outside of the polypropylene resin crushing chamber corresponding to the side of the first mounting plate. A second motor is fixedly installed on the top of the second mounting plate. A drive cylinder is fixedly installed inside the polypropylene resin crushing chamber.

[0006] Preferably, the outer wall of the crushing roller is fixed with a plurality of sets of crushing protrusions surrounding the crushing roller, the crushing protrusions being half-spherical, and both ends of the crushing roller extending rotatably out of the two sides of the polypropylene resin crushing box.

[0007] Preferably, a partition is fixedly installed between the inner walls of the two sides of the polypropylene resin crushing box, directly above the crushing roller.

[0008] Preferably, a placement plate is fixedly installed on the side of the partition between the inner walls of the two sides of the polypropylene resin crushing box, and a drive cylinder is fixed on the top of the placement plate.

[0009] Preferably, the pressing assembly includes a rotating shaft, a pressing plate, and a rotating gear. Two sets of rotating shafts are rotatably installed on the sides of the partition between the inner walls of the two sides of the polypropylene resin crushing chamber. The outer walls of both sets of rotating shafts are fitted with pressing plates for pressing. One end of each set of rotating shafts extends out of the polypropylene resin crushing chamber and is fitted with a rotating gear. The other end of one set of rotating shafts is fixedly connected to the output end of the second motor. Two sets of rotating gears mesh with each other, and both sides of the two sets of pressure plates are arc-shaped, with the ends of the two sets of pressure plates respectively attached to the inner walls of the two sides of the polypropylene resin crushing chamber.

[0010] Preferably, the pressing assembly further includes a cutting component, and the piston rod on the drive cylinder slides out to the other side of the partition and is fitted with the cutting component; The cut pieces are in the shape of equilateral triangles.

[0011] Compared with the prior art, this utility model provides a high-efficiency spiral crushing roller assembly device for polypropylene resin, which has the following beneficial effects: Collaborative crushing with pressing components: Through the rotation and horizontal squeezing action of the pressing plate, the material is pre-pressed above the crushing roller, avoiding the low crushing efficiency caused by material accumulation. The arc-shaped design of the pressing plate ensures a tight fit with the inner wall of the crushing chamber, preventing material leakage and improving the continuity of the crushing process.

[0012] Crushing and cutting work together to improve crushing efficiency: The drive cylinder pushes the equilateral triangular cutting piece to cut the crushed material, preventing the material from tangling or sticking to the surface of the crushing roller, ensuring that the crushing process is efficient and stable. The cutting action and the rotation and extrusion of the crushing roller work together to significantly improve crushing efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-3 A high-efficiency spiral crushing roller assembly for polypropylene resin includes: Polypropylene resin crushing chamber 1; A crushing roller 2 is rotatably installed inside a polypropylene resin crushing chamber 1. An extension shaft 4 is fixed at the center of one end of the crushing roller 2. A first mounting plate 5 is fixed on the outside of the polypropylene resin crushing chamber 1. A first motor 6 is fixedly installed on the top of the first mounting plate 5. A second mounting plate 7 is fixed on the outside of the polypropylene resin crushing chamber 1 corresponding to the side of the first mounting plate 5. A second motor 8 is fixedly installed on the top of the second mounting plate 7. A drive cylinder 11 is fixedly installed inside the polypropylene resin crushing chamber 1. A pressing assembly is installed between the inner walls of both sides of the polypropylene resin crushing chamber 1.

[0017] The output shaft of the first motor 6 is fitted with a pulley A17, and the end of the extension shaft 4 away from the crushing roller 2 is fitted with a pulley B18. A belt 9 is rotatably connected between the pulley A17 and the pulley B18.

[0018] The outer wall of the crushing roller 2 is fixed with several sets of crushing protrusions 3 surrounding the crushing roller 2. The crushing protrusions 3 are half-spherical. Both ends of the crushing roller 2 extend out of the two sides of the polypropylene resin crushing box 1.

[0019] A partition plate 12 is fixedly installed between the inner walls of the two sides of the polypropylene resin crushing box 1, directly above the crushing roller 2.

[0020] A placement plate 10 is fixedly installed on the side of the partition 12 between the inner walls of the two sides of the polypropylene resin crushing box 1, and a drive cylinder 11 is fixed on the top of the placement plate 10.

[0021] The pressing assembly includes a rotating shaft 13, a pressing plate 14, and a rotating gear 15. Two sets of rotating shafts 13 are rotatably installed between the inner walls of the two sides of the polypropylene resin crushing chamber 1, corresponding to the side of the partition 12. The outer walls of the two sets of rotating shafts 13 are fitted with pressing plates 14 for pressing. One end of each set of rotating shafts 13 extends out of the polypropylene resin crushing chamber 1 and is fitted with a rotating gear 15. The other end of one set of rotating shafts 13 is fixedly connected to the output end of the second motor 8. Two sets of rotating gears 15 mesh with each other, and both sides of the two sets of pressure plates 14 are arc-shaped and the two ends of the two sets of pressure plates 14 are respectively attached to the inner walls of the two sides of the polypropylene resin crushing box 1. The half-spherical crushing protrusions 3 on the surface of the crushing roller 2 cooperate with the pressure plates 14. Through rotation, extrusion and shearing, the high-toughness polypropylene resin material is efficiently crushed, solving the problem that traditional single shearing or extrusion methods are difficult to handle high-toughness materials. Through the multi-stage crushing method of shearing, extrusion and cutting, the fine powder generated by over-crushing is reduced, the output particle size distribution is optimized, and the difficulty of subsequent processing is reduced.

[0022] The pressing assembly also includes a cutting component 16, and the piston rod on the drive cylinder 11 slides out to the other side of the partition 12 and is fitted with the cutting component 16; The cut piece 16 is in the shape of an equilateral triangle.

[0023] Working principle: When polypropylene resin needs to be crushed, the second motor 8 is started first. The output end of the second motor 8 drives one set of rotating shafts 13 to rotate between the inner walls of the two sides of the polypropylene resin crushing chamber 1. The two sets of rotating shafts 13 rotate relative to each other through the meshing of rotating gears 15, causing the two sets of pressure plates 14 to rotate to a vertical position between the inner walls of the two sides of the polypropylene resin crushing chamber 1, placing the polypropylene resin between the two sets of pressure plates 14. Then, the first motor 6 is started. The output shaft of the first motor 6 drives the pulley A17 to rotate synchronously. The pulley A17 drives the pulley B18 to rotate synchronously through the transmission of belt 9. The extension shaft 4 rotates with the pulley B18. The rotation drives the crushing roller 2 to rotate inside the polypropylene resin crushing chamber 1. The crushing roller 2 rotates and crushes the polypropylene resin falling between the two sets of pressure plates 14 on the inner wall of the polypropylene resin crushing chamber 1. The rotating gear 15 continues to rotate, causing the two sets of pressure plates 14 to rotate to a horizontal position. During the process of rotating from a vertical position to a horizontal position, the two sets of pressure plates 14 squeeze the polypropylene resin between the crushing roller 2 and the pressure plates 14 downwards. As the drive cylinder 11 is started, the piston rod on the drive cylinder 11 pushes the cutting piece 16, causing the cutting piece 16 to cut the polypropylene resin between the pressure plates 14 and the crushing roller 2, making the crushing roller 2 more efficient during crushing.
