Description

[0002] The main component of plastic is resin. So-called plastic is actually a type of synthetic resin, similar in shape to the rosin found in natural resin. It is chemically synthesized and thus called plastic. Plastic particles, a common name for plastic granules, are the raw materials used to store, transport, and process plastics in semi-finished form. Plastics are a type of polymer material. Ethylene, propylene, vinyl chloride, styrene, and other materials can be produced from petroleum. Under certain conditions, the molecules of these substances can react with each other to form high-molecular-weight compounds, known as polymers.

[0003] When large plastic particles are further crushed into smaller particles, the large plastic particles directly enter the crushing equipment, causing the plastic particles to accumulate in the crushing equipment, resulting in reduced crushing efficiency and accelerating the wear rate of the crushing tool where the plastic particles are seriously accumulated.

[0033] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] The present invention will be further described below with reference to the embodiments.

[0035] See Figures 1 to 9 A plastic particle crushing device of this embodiment includes a crushing body 10, a rectangular frame 80 is fixedly connected to the top of the crushing body 10, a feed hopper 70 is connected to the top of the rectangular frame 80, a throwing mechanism 20 for reducing the accumulation of plastic particles is provided at the bottom of the rectangular frame 80, a closing mechanism 30 for controlling the falling speed of plastic particles in the feed hopper 70 is provided at the top of the rectangular frame 80, a blower mechanism 40 for removing dust from the plastic particles is provided inside the rectangular frame 80, impact mechanisms 50 are symmetrically provided on both sides of the feed hopper 70 to prevent blockage of plastic particles, and a swing mechanism 60 for driving the throwing mechanism 20 to move up and down is provided on the outside of the rectangular frame 80.

[0036] The spreading mechanism 20 includes a conveying hose 207 fixedly connected to the bottom of the rectangular frame 80. The conveying hose 207 is fixedly connected to a cylindrical outer shell 201 at one end away from the rectangular frame 80. A feed port 206 for plastic particles to enter is provided at the top of the outer shell 201, and the feed port 206 is communicated with the conveying hose 207. A discharge port 205 for plastic particles to be discharged is provided on the side of the outer shell 201.

[0037] The spreading mechanism 20 also includes a circular rotating disk 202 arranged inside the outer shell 201. A first motor 204 is fixedly connected to the bottom of the outer shell 201, and the output end of the first motor 204 extends to the inside of the outer shell 201. The output end of the first motor 204 is fixedly connected to the lower surface of the rotating disk 202, and a plurality of baffles 203 are fixedly connected to the upper surface of the rotating disk 202.

[0038] During specific operation, when large-particle plastic particles are crushed, the large-particle plastic particles are first put into the feed hopper 70, and the plastic particles pass through the rectangular frame 80 and enter the crusher body 10 for further crushing. The plastic particles enter the feed port 206 from the bottom of the rectangular frame 80 through the conveying hose 207, thereby inputting the plastic particles into the outer shell 201. After the plastic particles pass through the feed port 206, the plastic particles fall onto the surface of the rotating disk 202. Since the rotating disk 202 is driven by the first motor 204 to rotate at high speed, the baffle 203 on the surface of the rotating disk 202 blocks the falling plastic particles, driving the plastic particles falling on the surface of the rotating disk 202 to rotate synchronously, and under the action of centrifugal force, the plastic particles are thrown out from the discharge port 205, thereby throwing the plastic particles into the crusher body 10, reducing the load unevenness problem caused by local accumulation, helping to improve the working efficiency of the crusher, and allowing the plastic particles to be crushed faster and more effectively.

[0039] The closing mechanism 30 includes a cylinder 301 horizontally rotatably connected to the inside of the rectangular frame 80 , and both ends of the cylinder 301 extend to the outside of the rectangular frame 80 . A receiving groove 302 for containing plastic particles is symmetrically provided on the side of the cylinder 301 .

[0040] The closing mechanism 30 also includes ratchets 303 symmetrically fixedly connected to the two ends of the cylinder 301. A ring 304 is sleeved on the outside of each ratchet 303, and the ring 304 is rotatably connected to the side of the rectangular frame 80. A pawl 305 is rotatably connected to the side of the ring 304, and the pawl 305 is engaged with the ratchet 303. An elastic sheet 306 is also fixedly connected to the side of each ring 304, and the elastic sheet 306 fits tightly against the side of the pawl 305.

[0041] A shift rod 309 is fixedly connected to the side of the circular ring 304, and a U-shaped frame 307 is slidably sleeved on the outside of the shift rod 309. A bracket 308 is slidably sleeved on the outside of the U-shaped frame 307. The bracket 308 is fixedly connected to the side of the rectangular frame 80. Guide rods 310 are symmetrically fixedly connected at both ends of the U-shaped frame 307. The guide rods 310 are slidably connected to the protrusions on the side of the rectangular frame 80. A return spring 311 is sleeved on the outside of the guide rod 310, and the return spring 311 is located between the protrusions on the side of the rectangular frame 80 and the U-shaped frame 307.

[0042] When working, the cam 404 in the hair dryer mechanism 40 is used to push the U-shaped frame 307 to move along the bracket 308. When the U-shaped frame 307 moves, the ring 304 is driven to rotate counterclockwise through the lever 309. The counterclockwise rotating ring 304 drives the ratchet 303 to rotate counterclockwise synchronously through the pawl 305. At this time, the ratchet 303 drives the cylinder 301 to rotate synchronously, and the U-shaped frame 307 drives the guide rod 310 to move synchronously. When the cam 404 pushes the U-shaped frame 307, the return spring 311 is compressed. When the cam 404 does not squeeze the U-shaped frame 307, the return spring 311 pushes the U-shaped frame 307 in the opposite direction. When the U-shaped frame 307 is pushed back and forth to move, the U-shaped frame 307 drives the cylinder 301 to rotate. During the rotation of the cylinder 301, the plastic particles in the feed hopper 70 enter the receiving groove 302. When one of the receiving grooves 302 containing plastic particles rotates one hundred and eighty degrees, the plastic particles in the receiving groove 302 fall into the rectangular frame 80 under the action of gravity, thereby utilizing the two receiving grooves 302 on the surface of the cylinder 301 to intermittently transport the plastic particles to the pulverizer body 10, thereby achieving precise control of the feed amount, avoiding excessive feed causing excessive load on the pulverizing equipment, and reducing the risk of material jamming and blockage.

[0043] The hair dryer mechanism 40 includes a mounting hole 401 on the side of the rectangular frame 80, and a fan blade 402 is rotatably connected inside the mounting hole 401. A second motor 403 is fixedly connected to the surface of the rectangular frame 80 outside the mounting hole 401, and the output end of the second motor 403 is fixedly connected to the fan blade 402. The outside of the output end of the second motor 403 is also fixedly connected to a cam 404 for pushing the U-shaped frame 307 to move, and the cam 404 and the side of the U-shaped frame 307 conflict with each other. The hair dryer mechanism 40 also includes baffle plates 405 that are alternately fixedly connected to the inside of the rectangular frame 80, and each baffle plate 405 has a through hole 406 on its surface for airflow to pass through. A screen 407 is fixedly connected to the side of the rectangular frame 80 away from the fan blade 402.

[0044] During specific operation, when the plastic particles fall from the feed hopper 70 into the rectangular frame 80, the plastic particles roll down from multiple inclined baffles 405 in turn. During the rolling process, the second motor 403 is used to drive the fan blades 402 to rotate rapidly. The fan blades 402 blow the external airflow from the mounting hole 401 to the surface of the rolling plastic particles. The airflow passes through the through holes 406 on the surface of the baffle plate 405 and is discharged from the screen 407. In this process, the airflow blows away the dust mixed in the plastic particles, thereby improving the purity of the final product. By reducing the dust and other impurities in the plastic particles, the wear on the crushing equipment can be reduced, and the service life of the crushing equipment can be extended.

[0045] When the second motor 403 rotates, the second motor 403 synchronously drives the cam 404 to rotate, and the rotating cam 404 continuously pushes the U-shaped frame 307 to move back and forth.

[0046] The impact mechanism 50 includes multiple groups of rotating rods 501 rotatably connected to the side of the feed hopper 70. A hammer 502 is fixedly connected to the bottom of each rotating rod 501 near the side of the feed hopper 70, and each rotating rod 501 is bent away from the feed hopper 70 at one end away from the hammer 502.

[0047] The impact mechanism 50 also includes a mounting frame 505 fixedly connected to the side of the feed hopper 70, and a first slide groove 506 and a second slide groove 507 are opened on the side of the mounting frame 505. A moving rod 503 is slidably connected in the first slide groove 506, and an outer cylinder 504 for squeezing the top curved section of the rotating rod 501 is rotatably sleeved on the outside of the moving rod 503. Connecting rods 509 are fixedly connected at both ends of the moving rod 503, and the two connecting rods 509 are fixedly connected to each other by a support rod 510. A limiting rod 508 is fixedly connected to the side of each connecting rod 509, and the limiting rod 508 extends into the second slide groove 507, and the limiting rod 508 slides in the second slide groove 507.

[0048] A roller 511 is slidably connected to the bottom of each support rod 510 , and an extension rod 512 is fixedly connected to the side of the roller 511 . The end of the extension rod 512 away from the roller 511 is fixedly connected to the end of the guide rod 310 away from the U-shaped frame 307 .

[0049] When the cam 404 continuously pushes the U-shaped frame 307 to move back and forth, the U-shaped frame 307 drives the extension rod 512 to move synchronously through the guide rod 310. When the extension rod 512 moves upward, the extension rod 512 pushes the support rod 510 to move upward synchronously through the roller 511. The support rod 510 drives the moving rod 503 to move upward synchronously through the connecting rod 509. When the connecting rod 509 moves, it is restricted by the limit rod 508 to prevent the position of the connecting rod 509 from being offset. At this time, the moving rod 503 slides in the first slide groove 506, and the outer cylinder 504 on the outside of the moving rod 503 squeezes the curved top of the rotating rod 501. The curved section causes the rotating rod 501 to rotate upward. At this time, the hammer 502 at the bottom of the rotating rod 501 moves away from the side of the feed hopper 70, and then moves in the direction of the U-shaped frame 307 driven by the return spring 311. At this time, the moving rod 503 drives the outer cylinder 504 to separate from the curved section of the rotating rod 501. Under the action of the gravity of the hammer 502, the hammer 502 hits the side of the feed hopper 70, causing the feed hopper 70 to shake. During the shaking process, the feed hopper 70 can effectively prevent the accumulation and blockage of plastic particles in the feed hopper 70, which helps to improve the fluidity of the material and allows the plastic particles to enter the crushing equipment more smoothly.

[0050] The swing mechanism 60 includes connecting shafts 603 symmetrically fixedly connected to the side of the outer shell 201, and each connecting shaft 603 is rotatably connected to the crusher body 10 at one end away from the outer shell 201, and a steel cable 601 is fixedly connected to the top of the outer shell 201, and the end of the steel cable 601 away from the outer shell 201 slides through the outside of the crusher body 10, and the end of the steel cable 601 away from the outer shell 201 is fixedly connected to the side of the U-shaped frame 307, and a guide wheel 602 is fixedly connected to the side of the rectangular frame 80, and the surface of the guide wheel 602 is slidably connected to the steel cable 601.

[0051] During specific operation, when the U-shaped frame 307 moves upward, the outer shell 201 is pulled to rotate synchronously by the steel cable 601, and the outer shell 201 rotates with the connecting shaft 603 as the rotation axis. When the U-shaped frame 307 moves downward, the outer shell 201 rotates in the opposite direction under the action of gravity. The outer shell 201 swings back and forth in this way, thereby evenly throwing the plastic particles into the crusher body 10.

[0052] Working principle:

[0053] When the plastic particles are crushed, the plastic particles fall from the feed hopper 70 into the rectangular frame 80. The closing mechanism 30 controls the intermittent and quantitative drop of the plastic particles from the feed hopper 70 into the rectangular frame 80. At the same time, the closing mechanism 30 drives the impact mechanism 50 to impact the feed hopper 70. During the shaking process, the feed hopper 70 can effectively prevent the accumulation and blockage of plastic particles in the feed hopper 70, which helps to improve the fluidity of the material and make the plastic particles enter the crushing equipment more smoothly. After the plastic particles enter the rectangular frame 80, the dust in the plastic particles is removed by the air blowing mechanism 40. Finally, the plastic particles enter the sprinkling mechanism 20 and sprinkle the plastic particles into the crushing machine body 10. At the same time, the U-shaped frame 307 in the closing mechanism 30 drives the sprinkling mechanism 20 to swing back and forth through the swinging mechanism 60, so that the plastic particles are more evenly sprinkled in the crushing machine body 10.
