Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle production, in particular to a PP recycled plastic particle spheroidizing and molding device. Background Art

[0002] PP recycled material refers to the recycled material of polypropylene plastic. Recycling also means recycling. It is the general name for the raw materials after the second thermoplastic treatment relative to new raw materials. Plastic granules are granules processed from waste plastics. They have a wide range of uses. In daily life, plastic granules can be used to make various plastic bags, buckets, basins, toys, furniture, stationery and other daily necessities and various plastic products.

[0003] In the prior art, for example, Chinese Patent CN215039267U discloses a device for spheroidizing plastic particles. The device comprises a bracket on which a forming mechanism and a cooling mechanism are fixedly mounted. Both the forming mechanism and the cooling mechanism are obliquely mounted on the bracket, with the cooling mechanism fixedly mounted below the lower end of the forming mechanism. The forming mechanism comprises a forming cylinder and a plurality of curved forming tubes fixedly mounted transversely within the cylinder, forming a cooling cavity between the forming tubes and the inner wall of the cylinder. Both ends of the cylinder are fixedly connected to guide plates, each of which is provided with guide holes that cooperate with the forming tubes. The cooling mechanism comprises an obliquely mounted cooling water trough, a cooling water spray pipe fixedly mounted on the bracket above the higher end of the cooling water trough, and a drainage pipe connected to the bottom of the lower end of the cooling water trough. This device is rationally designed and easy to use. By cooling and rolling the hot, soft plastic particles, it can effectively achieve spheroidization of the plastic particles with good results and high efficiency.

[0004] In the above patent, the plastic particles are still in a hot and soft state. After being discharged, they roll down through the air duct and are rounded by the natural force of rolling. However, this natural rolling spherical method requires a longer slope surface. If the rolling distance is short, the recycled plastic particles are difficult to be fully rounded. If the slope surface is long, the slope surface needs to be extended, which will inevitably increase the overall floor space. The company needs to plan a larger indoor area, which is inconvenient for some companies with narrow indoor space to use. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: Figure 1-Figure 5 As shown, the utility model provides a PP recycled plastic granule spheroidizing molding device, comprising: a box body 1, a molding assembly 3 is arranged on the top of the box body 1; the molding assembly 3, the molding assembly 3 includes an outer tube 301, the outer tube 301 is fixedly connected to the top of the box body 1, the outer tube 301 is connected to the box body 1, a hopper 303 is arranged on the top of the outer tube 301, the hopper 303 is connected to the outer tube 301, an inner tube 304 is arranged inside the outer tube 301, a spiral sheet 305 is fixedly connected between the outer tube 301 and the inner tube 304, a plurality of first air holes 302 are evenly opened on the outer surface of the outer tube 301 near the bottom, and a plurality of second air holes 304 are evenly opened on the outer surface of the inner tube 304 6. A first mounting bracket 307 is fixedly connected to the inner surface of the inner tube 304 near the bottom, and a first fan 308 is arranged on the top of the first mounting bracket 307. A hollow block 2 is fixedly connected to the top of the box body 1, and the inner wall of the hollow block 2 fits with the outer surface of the outer tube 301. The outer surfaces on both sides of the hollow block 2 are symmetrically fixedly connected with outer ring blocks 4, and the inner surfaces of multiple outer ring blocks 4 are fixedly connected with a second mounting bracket 5. The outer ring blocks 4 are connected to the hollow blocks 2. A second fan 11 is arranged on the outer surface of the second mounting bracket 5, and the second fan 11 is located on the inner side of the outer ring block 4. Two collecting boxes 8 are respectively arranged on the inner surface of the box body 1, and a plurality of filter holes are evenly opened on the inner bottom of one of the collecting boxes 8.

[0026] The effect achieved by the entire embodiment 1 is that when the PP recycled material particles are spheroidized, the recycled material squeezed into granular form by the external equipment will roll along the arc surface of the hopper 303 to its center when it falls into the hopper 303, and fall between the outer tube 301 and the inner tube 304. By fixing the spiral piece 305 between the outer tube 301 and the inner tube 304, the recycled particles in the hot and soft state will roll downward along the spiral piece 305 under the action of gravity, and gradually become spherical during the rolling process. At the same time, the first fan 308 fixed on the top of the first mounting frame 307 and the second fan 11 fixed on the surface of the second mounting frame 5 are started. The first fan 308 will guide the external cold air flow to move upward and discharge it evenly from the multiple second air holes 306, so that the recycled particles will be spheroidized. The hot soft plastic particles can be pre-cooled, and multiple second fans 11 will guide external air into the hollow block 2, so that the external air can pass through the multiple first air holes 302 opened on the surface of the outer tube 301, accelerating the air flow speed between the outer tube 301 and the inner tube 304, so that the spherical plastic particles rolling to the bottom can be cooled, so that when they fall into the box 1, they can be quickly solidified and formed, avoiding the deformation of the spherical plastic particles when falling into the collection box 8. The recycled plastic particles are spheroidized by spiral rolling, which greatly reduces the overall required floor space and avoids the need for enterprises to plan a large indoor area for installation. It is convenient for some enterprises with narrow indoor space to use, and improves the use effect of the PP recycled plastic particle spheroidization molding device.

[0027] Example 2: Figure 1-Figure 5 As shown, the outer surfaces of both sides of the two collection boxes 8 are respectively provided with slide grooves 9, and the inner surface of the box body 1 is symmetrically fixedly connected with sliders 10 on both sides. The sliders 10 and the slide grooves 9 are matched with each other. The rear surface of the box body 1 is symmetrically fixedly connected with mounting plates 6, and magnets 7 are provided on the inner surfaces of the two mounting plates 6. The front surfaces of the two magnets 7 are respectively in contact with the rear surfaces of the two collection boxes 8.

[0028] The effect achieved by the entire embodiment 2 is that, when in use, two collecting boxes 8 are arranged inside the box body 1, and a plurality of filter holes are opened on the inner bottom of one of the collecting boxes 8, which can intercept recycled plastic particles with too large diameter or deformation, thereby playing a filtering role. The two collecting boxes 8 are slidably connected to the multiple sliders 10 in the box body 1 through the slide grooves 9 opened on both sides, which is convenient for people to take out and use. The mounting plates 6 are symmetrically fixedly connected to the rear surface of the box body 1, and magnets 7 are set on the inner surfaces of the two mounting plates 6. When the two collecting boxes 8 collect the spheroidized plastic particles, the rear surface of the metal collection box 8 is magnetically attracted to avoid the collection box 8 from shaking easily, causing its position to shift and affect the material collection effect, and the practicability is high.

[0029] Working principle: When PP recycled material particles are spheroidized, the recycled material squeezed into granular form by external equipment will roll along the arc surface of the hopper 303 to its center when it falls into the hopper 303, and fall between the outer tube 301 and the inner tube 304. By fixing the spiral piece 305 between the outer tube 301 and the inner tube 304, the recycled particles in the hot and soft state will roll downward along the spiral piece 305 under the action of gravity, and gradually become spherical during the rolling process. At the same time, the first fan 308 fixed on the top of the first mounting bracket 307 and the second fan 11 fixed on the surface of the second mounting bracket 5 are started. The first fan 308 will guide the external cold air flow to move upward and evenly discharge it from the multiple second air holes 306, so that the hot and soft plastic particles during rolling spheroidization can be pre-cooled. The multiple second fans 11 will guide the external air into the hollow block 2, so that the external air can pass through the multiple first air holes 3 opened on the surface of the outer tube 301 02. Accelerate the air flow speed between the outer tube 301 and the inner tube 304, so that the spherical plastic particles rolling to the bottom can be cooled, so that they can be quickly solidified and formed when falling into the box body 1, avoiding the deformation of the spherical plastic particles when falling into the collection box 8. By arranging two collection boxes 8 inside the box body 1, a plurality of filter holes are opened at the inner bottom of one of the collection boxes 8, which can intercept recycled plastic particles with too large diameter or deformation, and play a filtering role. The two collection boxes 8 are slidably connected to the multiple sliders 10 in the box body 1 through the slide grooves 9 opened on both sides, which are convenient for people to take out and use. By symmetrically fixing the mounting plates 6 on the rear surface of the box body 1, magnets 7 are set on the inner surfaces of the two mounting plates 6. When the two collection boxes 8 collect the spherical plastic particles, the rear surface of the metal collection box 8 can be magnetically attracted to avoid the collection box 8 from shaking easily, causing its position to shift and affect the material collection effect, and it is highly practical.
