Description

Technical Field

[0001] The invention relates to the technical field of recycling waste plastic products, and in particular to an EPP waste plastic product recycling and crushing device. Background Art

[0002] EPP is the abbreviation of expanded polypropylene, which is the abbreviation of a new type of foam plastic. EPP is a polypropylene plastic foam material, a highly crystalline polymer / gas composite material with excellent performance. With its unique and superior performance, it has become the fastest growing new environmentally friendly pressure-resistant buffer insulation material. EPP is also an environmentally friendly material that can be recycled.

[0003] When EPP is recycled, it needs to be broken by a breaking device. The Chinese patent with patent announcement number CN222132045U discloses a plastic plate breaking device, including: a breaking bucket, both side walls of the breaking bucket are equipped with electric cylinders, the output end of the electric cylinder is connected to a U-shaped plate, and a breaking roller is rotatably installed between the two ends of the U-shaped plate. The top of the U-shaped plate is provided with a conveying mechanism for automatically conveying the plastic plate, and a feed trough is provided in the middle of the top of the breaking bucket. The top of the feed trough is provided with a dustproof mechanism to prevent the dust generated when the plastic plate is broken from being dispersed into the air. Through the setting of the dustproof mechanism, when breaking, the dustproof box blocks the feed trough, and the arc rod drives the dustproof box to press against the feed trough through the restoring force of the spring, thereby improving the stability of the dustproof box. After the dustproof box blocks the feed trough, the dust generated by the breaking can be prevented from being dispersed into the air, thereby avoiding air pollution. However, when the above device is used to break the plastic, the plastic cannot be completely broken, resulting in the existence of larger fragments.

DETAILED DESCRIPTION

[0027] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0028] Example 1, reference Figure 1-Figure 4, an EPP plastic waste product recycling and shredding device, comprising a shredding box 1, both sides of the outer wall of the shredding box 1 are provided with a feed port 2, and the inner wall at the bottom of the feed port 2 is fixedly connected with a placement plate 3, a discharge port 5 is arranged at the bottom of the shredding box 1, a U-shaped frame 15 is arranged above the two placement plates 3, and a driving mechanism 1 is arranged between the two U-shaped frames 15, a knocking column 10 is rotatably connected between the two U-shaped frames 15, and a driving mechanism 2 is arranged at one end of the knocking column 10, a plurality of crushing cones 16 are equidistantly fixedly connected to the outer wall of the bottom of the knocking column 10, and an annular groove 20 is provided between two adjacent crushing cones 16, the annular groove 20 is cocentric with the knocking column 10, and a rotating cylinder 21 is rotatably connected to the outer wall of each annular groove 20, a crushing cone 2 17 is fixedly connected to the outer wall of the bottom of the rotating cylinder 21, and the crushing cone 2 17 is staggered with the crushing cone 16, and a plurality of gear teeth 22 are equidistantly arranged on the outer wall of each rotating cylinder 21, U A driving mechanism 3 is arranged on the top outer wall of the mold frame 15, and the plastic waste product is placed on the placement plate 3, and then pushed into the crushing box 1 through the feed port 2. In this process, the driving mechanism 1 causes the knocking column 10 to knock the plastic waste product. When the knocking column 10 contacts the plastic waste product, the multiple crushing cones 16 on the knocking column 10 will be inserted into the plastic waste product, and at the same time, the crushing cones 2 17 on each rotating cylinder 21 will be inserted into the plastic waste product at the same time. When the crushing cones 1 16 and 17 are both inserted into the plastic waste product, the driving mechanism 2 is started to rotate the knocking column 10. At the same time, the rotation of the knocking column 10 will start the driving mechanism 3, and the driving mechanism 3 will cause the multiple rotating cylinders 21 on the knocking column 10 to rotate, so that the multiple crushing cones 1 16 and 17 arranged in an interlaced manner are close to each other, which can split the plastic into smaller pieces, greatly improving the effect of processing plastics and facilitating subsequent processing.

[0029] As a further solution in the present invention, the driving mechanism 1 includes two rotating shafts 8, the two rotating shafts 8 are rotatably connected to the inside of the crushing box 1, and the same ends of the two rotating shafts 8 are fixedly connected to gears 7, the two gears 7 are meshed with each other, a driving motor 4 is provided at the other end of one of the rotating shafts 8, and two connecting plates 6 are fixedly connected between the rotating shaft 8 and the corresponding U-shaped frame 15, the driving motor 4 drives the rotating shaft 8 connected thereto to reciprocate forward and reverse, because the gears 7 on the two rotating shafts 8 are meshed with each other, the other rotating shaft 8 will rotate and the rotation direction is opposite, thereby being able to drive the knocking column 10 to knock the plastic waste products.

[0030] As a further solution in the present invention, the driving mechanism 2 includes an electric push rod 14, which is installed on the outer wall of the U-shaped frame 15, and the telescopic end of the electric push rod 14 is fixedly connected to the moving plate 13, and the outer wall of the moving plate 13 is fixedly connected to the rack 19. A gear 3 18 is provided at one end of the knocking column 10, and the gear 3 18 is meshed with the rack 19. The electric push rod 14 causes the rack 19 to reciprocate through the moving plate 13. Because the rack 19 is meshed with the gear 3 18 on the knocking column 10, the knocking column 10 can rotate when the rack 19 moves.

[0031] As a further scheme in the present invention, the driving mechanism three includes two mounting plates 9, a rotating shaft 2 12 is rotatably connected between the two mounting plates 9, and a transmission wheel 1 23 is fixedly connected to the outer wall of the rotating shaft 2 12, a transmission wheel 25 is arranged on the outer wall of the other end of the knocking column 10, and a transmission belt 24 is sleeved between the transmission wheel 25 and the transmission wheel 1 23, a plurality of gears 2 11 are fixedly connected to the outer wall of the rotating shaft 2 12 at equal distances, and the gears 2 11 are all meshed with the gear teeth 22 on the outer wall of the corresponding rotating cylinder 21, when the knocking column 10 rotates, the rotating shaft 2 12 rotates synchronously under the transmission action of the transmission wheel 1 23, the transmission belt 24 and the transmission wheel 2 25, because the plurality of gears 2 11 on the rotating shaft 2 12 are all meshed with the gear teeth 22 on the outer wall of the corresponding rotating cylinder 21, so that the rotating cylinder 21 can rotate when the rotating shaft 2 12 rotates, and the rotation direction of the rotating cylinder 21 is opposite to that of the knocking column 10, so that the plurality of staggered crushing cones 1 16 and crushing cones 2 17 can be brought close to each other.

[0032] Working principle: Place the waste plastic products on the placement plate 3, and then push them into the crushing box 1 through the feed port 2. During this process, the driving motor 4 drives the connected shaft 8 to reciprocate and reverse. Because the gears 7 on the two shafts 8 are meshed with each other, the other shaft 8 will rotate and the rotation direction is opposite, so that the knocking column 10 can be driven to knock the waste plastic products. When the knocking column 10 contacts the waste plastic products, the multiple crushing cones 16 on the knocking column 10 will be inserted into the waste plastic products, and the crushing cones 17 on each rotating cylinder 21 will be inserted into the waste plastic products at the same time. When the crushing cones 16 and 17 are both inserted into the waste plastic products, the electric push rod 14 passes through the moving plate 13 The rack 19 is made to move back and forth, because the rack 19 is meshed with the gear three 18 on the knocking column 10, so that the knocking column 10 can be rotated when the rack 19 moves, and when the knocking column 10 rotates, the rotating shaft 2 12 is synchronously rotated under the transmission action of the transmission wheel 1 23, the transmission belt 24 and the transmission wheel 2 25, because the multiple gears 2 11 on the rotating shaft 2 12 are all meshed with the gear teeth 22 on the outer wall of the corresponding rotating cylinder 21, so that when the rotating shaft 2 12 rotates, the rotating cylinder 21 can be rotated, and the rotation direction of the rotating cylinder 21 is opposite to that of the knocking column 10, so that the multiple staggered crushing cones 1 16 and crushing cones 2 17 can be close to each other, which can split the plastic into smaller pieces, greatly improving the effect of processing plastics and facilitating subsequent processing.

[0033] Example 2, reference Figure 1-Figure 5 , an EPP plastic waste product recycling and crushing equipment, compared with embodiment 1, on the basis of embodiment 1, a mounting cavity 26 is arranged directly above each feed port 2, and an electromagnet 27 is arranged on the top inner wall of the mounting cavity 26, a magnetic plate 29 is slidably connected to the inner wall of the mounting cavity 26, and a plurality of connecting springs 28 are fixedly connected between the magnetic plate 29 and the electromagnet 27, and the magnetic force generated by the electromagnet 27 after being energized attracts the magnetic plate 29. When the plastic waste products need to be crushed, the electromagnet 27 is first energized, because the magnetic force generated by the electromagnet 27 after being energized attracts the magnetic plate 29, so that the magnetic plate 29 compresses the connecting spring 28 and approaches the electromagnet 27.

[0034] As a further solution in the present invention, two sliding rods 30 are slidably connected at the connection between the feed port 2 and the mounting cavity 26, and the top of the sliding rod 30 is fixedly connected to the magnetic plate 29, and the bottom ends of the two sliding rods 30 are fixedly connected to a U-shaped frame 31, and the inner wall of the U-shaped frame 31 is rotatably connected to a pressing roller 32. At this time, the distance between the pressing roller 32 and the placement plate 3 is the largest, and then the plastic waste products are placed on the placement plate 3, and then enter the crushing box 1 through the feed port 2. At this time, the electromagnet 27 is powered off, and no magnetic force is generated after the electromagnet 27 is powered off. Therefore, under the action of the rebound force of the connecting spring 28, the pressing roller 32 contacts and presses the plastic waste products, so that the plastic waste products can stably enter the crushing box, avoiding the plastic waste products from warping up and being unable to be crushed.

[0035] Working principle: when it is necessary to break the waste plastic products, firstly, the electromagnet 27 is energized. The magnetic force generated by the electromagnet 27 after being energized attracts the magnetic plate 29, so that the magnetic plate 29 compresses the connecting spring 28 to be close to the electromagnet 27. At this time, the distance between the pressing roller 32 and the placing plate 3 is the largest. Then, the waste plastic products are placed on the placing plate 3, and then enter the breaking box 1 through the feed port 2. At this time, the electromagnet 27 is powered off. After the electromagnet 27 is powered off, no magnetic force is generated. Therefore, under the action of the rebound force of the connecting spring 28, the pressing roller 32 contacts and presses the waste plastic products, so that the waste plastic products can stably enter the breaking box, and avoid the waste plastic products from warping up and being unable to be broken.

[0036] Example 3, reference Figure 1-Figure 7 , an EPP plastic waste product recycling and crushing equipment, compared with Example 2, on the basis of Example 2, two electric push rods 3 35 are fixedly connected to the outer walls on both sides of the crushing box 1, and the telescopic ends of the electric push rods 3 35 are fixedly connected to the electric push rods 2 34, and the telescopic ends of the electric push rods 2 34 on the same side are fixedly connected to the same mounting groove 33.

[0037] As a further solution of the present invention, a bidirectional threaded rod 39 is rotatably connected inside the mounting groove 33, and a driving motor 2 38 is provided at one end of the bidirectional threaded rod 39. The outer walls of both sides of the bidirectional threaded rod 39 are slidably connected with threaded sliders 40, and the outer walls of the threaded sliders 40 are hinged with connecting plates 37, and the same end of the two connecting plates 37 is hinged with the same push plate 36. The position height of the electric push rod 2 34 can be adjusted by the electric push rod 35, so that the height of the mounting groove 33 at the telescopic end of the electric push rod 2 34 can be adjusted synchronously, so that the push plate 36 and the plastic waste product can be adjusted. The farthest outer wall is contacted, and then the electric push rod 2 34 makes the installation groove 33 move at a uniform speed, so that the plastic waste products are pushed into the crushing box 1 through the feed port 2 at a uniform speed through the push plate 36, until the push plate 36 enters the feed port 2, and then the driving motor 2 38 makes the bidirectional threaded rod 39 rotate, and the threaded sliders 40 on the outer walls on both sides of the bidirectional threaded rod 39 will approach each other, so that the push plate 36 continues to move into the crushing box 1 through the connecting plate 37, until the plastic waste products are completely pushed into the crushing box 1, and the crushing work is completed, without manual pushing, which greatly improves the work efficiency.

[0038] Working principle: The position height of the electric push rod 2 34 can be adjusted by the electric push rod 35, so that the height of the installation groove 33 at the telescopic end of the electric push rod 2 34 can be adjusted synchronously, so that the push plate 36 contacts the outer wall of the farthest end of the plastic waste product, and then the electric push rod 2 34 makes the installation groove 33 move at a uniform speed, so that the plastic waste product is pushed into the crushing box 1 through the feed port 2 at a uniform speed by the push plate 36, until the push plate 36 enters the feed port 2, and then the driving motor 2 38 makes the bidirectional threaded rod 39 rotate, and the threaded sliders 40 on the outer walls on both sides of the bidirectional threaded rod 39 will approach each other, so that the push plate 36 continues to move into the crushing box 1 through the connecting plate 37, until the plastic waste product is completely pushed into the crushing box 1, and the crushing work is completed, without manual pushing, which greatly improves the work efficiency.
