Description

Technical Field

[0001] This utility model relates to the field of waste plastic recycling technology, specifically a waste plastic recycling and crushing device. Background Technology

[0002] Waste plastic recycling refers to the systematic process of transforming waste plastics into new resources or energy materials through physical or chemical methods, in order to achieve resource recycling and reduce environmental pollution.

[0003] Patent CN211105025U discloses a crushing and recycling device for waste plastic pipes. It includes a crushing box with a feed inlet at the top. Triangular blocks are fixedly installed on both sides of the top of the crushing box, and rollers are movably installed on both sides of the middle of the crushing box. The device is driven by a motor, which rotates one roller and a rotating gear. The rotating gear drives another rotating gear and roller to rotate, ensuring that the two rollers rotate relative to each other and squeeze the material. At the same time, the crushing blades crush the material. After being crushed, the material continues to fall and is further pulverized by the high-speed rotation of the rotating blades.

[0004] However, the existing device directly feeds waste plastic into the inlet and performs secondary crushing using crushing blades and rotating blades. In this crushing method, the waste plastic spends a short time in the crushing box and is discharged directly from the bottom of the crushing box after secondary crushing. As a result, it is difficult to ensure that the size of the crushed waste plastic particles meets the requirements. Therefore, a waste plastic recycling and crushing device is proposed to solve the problem that the existing crushing device cannot guarantee that the plastic can be completely crushed.

[0015] (III) Beneficial Effects

[0016] 1. This waste plastic recycling and crushing device puts waste plastic into the crushing chamber from the top of the crushing box. With the help of the guide block, the plastic is guided to the crushing roller for crushing. At the same time, the motor is turned on to drive the rotating shaft to rotate, so that the initially crushed plastic falls into the crushing cylinder and is crushed by the crushing blades, ensuring that the plastic can be completely crushed. Then, the electric telescopic rod is turned on with the connecting block to move the crushing cylinder out of the crushing chamber, so that the completely crushed plastic can be discharged from the discharge port. This solves the problem that existing crushing devices cannot guarantee the complete crushing of plastic.

[0017] 2. This waste plastic recycling and crushing device will inevitably generate dust during the crushing process of plastic by crushing rollers and crushing blades. At this time, turning on the dust pump in conjunction with the dust suction pipe and the dust suction holes on the dust suction seat in the slot can absorb all the dust generated by crushing in the crushing chamber into the dust collection box, thereby improving the functionality of this waste plastic recycling and crushing device and preventing dust from overflowing and polluting the environment and affecting personnel health.

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.

[0024] Example: Please refer to Figure 1-4 A waste plastic recycling and crushing device includes a base 1, a support column 2 fixedly connected to the top of the base 1, a crushing box 3 fixedly connected to the top of the support column 2, a crushing chamber 4 inside the crushing box 3, crushing rollers 5 symmetrically arranged on the top of the crushing chamber 4, a crushing cylinder 6 slidably arranged through the middle of the crushing chamber 4, a rotating shaft 7 rotatably connected to the inner cavity of the crushing chamber 4, a crushing blade 8 fixedly connected to the outer ring of the rotating shaft 7, a dust removal mechanism 9 outside the crushing box 3, a motor 10 fixedly connected to one end of the crushing box 3, a screening mechanism 11 at the bottom of the crushing box 3, a discharge port 12 at the bottom of the crushing box 3, guide blocks 13 symmetrically arranged on the top of the crushing chamber 4, a connecting block 14 fixedly connected to one end of the crushing cylinder 6, and electric telescopic rods 15 fixedly connected to both sides of the crushing box 3.

[0025] Furthermore, the crushing roller 5 is driven by an external drive device, and the two rotate towards each other in the middle, with the discharge port 12 communicating with the inner cavity of the crushing chamber 4.

[0026] Furthermore, the output shaft of the motor 10 extends through the crushing chamber 4 and is fixedly connected to the rotating shaft 7. When the crushing cylinder 6 is located in the inner cavity of the crushing chamber 4, the rotating shaft 7 and the lower half of the crushing blade 8 are both located in the inner cavity of the crushing cylinder 6.

[0027] Furthermore, the dust removal mechanism 9 includes a slot 901 that runs through both ends of the crushing chamber 3. The inner cavity of the slot 901 is provided with a dust suction seat 902. The dust suction seat 902 is hollow inside and has a dust suction hole 903 at one end facing the crushing chamber 4.

[0028] Furthermore, a dust suction pipe 904 is installed on the outside of the crushing chamber 3, which is connected to the inner cavity of the dust suction seat 902. A dust suction pump 905 and a dust collection box 906 are installed on one side of the crushing chamber 3. The dust suction pump 905 is connected to both the dust suction pipe 904 and the dust collection box 906. Dust will inevitably be generated during the crushing of plastic by the crushing roller 5 and the crushing blade 8. At this time, by turning on the dust suction pump 905 in conjunction with the dust suction pipe 904 and the dust suction hole 903 on the dust suction seat 902 in the slot 901, all the dust generated in the crushing chamber 4 due to crushing can be absorbed into the dust collection box 906, thereby improving the functionality of this waste plastic recycling crushing device and preventing dust from overflowing and polluting the environment and affecting personnel health.

[0029] Furthermore, the screening mechanism 11 includes a limiting groove 111 opened on the opposite side of the support column 2, a screening frame 112 is slidably arranged in the inner cavity of the limiting groove 111, and a collection box 113 is arranged at the bottom of the screening frame 112.

[0030] Furthermore, the inner cavity of the screening frame 112 is provided with a screen plate 114, and a linkage plate 115 is fixedly connected to one end of the screening frame 112.

The screen plate 114 with the required aperture is selected in advance and placed in the screening frame 112. When the crushed plastic is discharged from the discharge port 12, it will be directly discharged into the screening frame 112. At this time, the electric push rod 116 is turned on in conjunction with the linkage plate 115 and the limiting slide groove 111, which can drive the screening frame 112 to move and screen the plastic inside, which then falls into the collection box 113, further improving the functionality of this waste plastic recycling crushing device and making it easier to obtain plastic particles of different sizes according to needs.

[0031] Working principle: When using this waste plastic recycling and crushing device, waste plastic is put into the crushing chamber 4 from the top of the crushing box 3. With the help of the guide block 13, the plastic is guided to the crushing roller 5 for crushing. At the same time, the motor 10 is turned on to drive the rotating shaft 7 to rotate, so that the initially crushed plastic falls into the crushing cylinder 6 and is crushed by the crushing blade 8, ensuring that the plastic can be completely crushed. Then, the electric telescopic rod 15 is turned on with the connecting block 14 to move the crushing cylinder 6 out of the crushing chamber 4, so that the completely crushed plastic can be discharged from the discharge port 12. This solves the problem that existing crushing devices cannot guarantee the complete crushing of plastic.
