Description

Technical Field

[0001] This utility model relates to the field of plastic bottle processing technology, specifically to a crushing device for plastic bottle processing. Background Technology

[0002] In the field of plastic bottle recycling and processing, crushing equipment is a key component. Traditional crushing equipment suffers from low crushing efficiency, high energy consumption, poor adaptability to different sizes of plastic bottles, and is prone to jamming, leading to production interruptions. Meanwhile, the dust and noise pollution generated during the crushing process also urgently needs to be addressed. Furthermore, the blades of existing equipment wear out quickly and require frequent replacement, increasing maintenance costs and downtime. Therefore, there is an urgent need for a more efficient, energy-saving, environmentally friendly, and adaptable crushing device.

[0003] According to a patent application published on the internet (authorization announcement number: CN216831781U), "This utility model discloses a high-efficiency crushing device for plastic bottle processing, relating to the field of plastic bottle processing technology. This utility model includes a crushing box, with a funnel mounted on the upper surface of the crushing box. Cylinders and limiting rods are mounted on both sides of the funnel. Cylinders are connected to crushing blades, and one end of the limiting rod is fixedly connected to the crushing blades. A first connecting rod and a second connecting rod are installed inside the crushing box. The first connecting rod is connected to a first crushing wheel, and the second connecting rod is connected to a second crushing wheel. Crushing teeth are mounted on the circumferential side of the first crushing wheel, and crushing grooves are provided on the circumferential side of the second crushing wheel. This utility model, by setting cylinders and crushing blades, allows plastic bottles to be fed into the funnel. The two cylinders push the crushing blades closer to each other, thus performing the first crushing treatment on the plastic bottle. After the first crushing, the plastic falls into the crushing box, where the first and second crushing wheels rotate, and the crushing teeth perform secondary crushing on the plastic in the crushing grooves, improving the crushing quality of the equipment."

[0004] Based on the above, the applicant believes the following deficiencies exist:

[0005] Existing plastic bottle crushing devices are mostly single-layer crushing structures, lacking reliable screening and secondary crushing mechanisms, with insufficient power control precision, simple blade design, easy clogging, poor finished product particle size control, low crushing efficiency and high energy consumption, large particle residue, unstable crushing quality, difficulty in adapting to diversified processing needs, frequent shutdowns for cleaning, and poor production continuity. Utility Model Content

[0006] The purpose of this invention is to provide a crushing device for processing plastic bottles, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a crushing device for processing plastic bottles, comprising a crushing chamber, a feeding port fixedly connected to the bottom end of the crushing chamber, a dust collection chamber fixedly connected to the bottom end of the feeding port, a secondary crushing chamber fixedly connected to the bottom end of the dust collection chamber, and a screening chamber fixedly connected to the bottom end of the secondary crushing chamber. Plastic bottle processing crushing mechanisms are provided on the surfaces of the crushing chamber, the dust collection chamber, and the secondary crushing chamber. The plastic bottle processing crushing mechanism includes a plastic bottle crushing component and a dust collection component. A vibrating screening mechanism is provided on the surface of the screening chamber. A feeding port is fixedly connected to the top of the crushing chamber, and bases are fixedly connected to the left and right ends of the screening chamber.

[0008] The plastic bottle crushing assembly includes a first crushing roller rotatably connected to the inside of a crushing chamber. A first crushing blade is fixedly connected to the surface of the first crushing roller. A motor frame is fixedly connected to the right end of the crushing chamber, and a first servo motor is installed inside the motor frame. Inclined filter plates are fixedly connected to the left and right ends inside the secondary crushing chamber. A second crushing roller is rotatably connected inside the secondary crushing chamber, and a second crushing blade is fixedly connected to the surface of the second crushing roller. A second servo motor is installed on the back of the secondary crushing chamber. This assembly is designed as a double-layer crushing structure. The first crushing roller is rotated by the first servo motor, and the plastic bottle is crushed for the first time by the first crushing blade. Then, the crushed fragments fall into the secondary crushing chamber. Fragments of suitable size fall through the inclined filter plate, while fragments of unsuitable size are crushed for the second time by the second crushing roller driven by the second servo motor. This can achieve both primary crushing and secondary fine crushing of plastic bottles, ensuring that the plastic bottles are fully crushed and reducing the residue of large particles. Through the shearing and impact action of the blades, the plastic bottles can be effectively crushed into smaller particles, improving the crushing quality.

[0009] Preferably, the first crushing roller is fixedly connected to the left output end of the first servo motor, and the second crushing roller is fixedly connected to the front output end of the second servo motor.

[0010] Preferably, the first crushing roller, the motor frame, the first servo motor, the inclined filter plate, the second crushing roller, and the second servo motor are all provided in two sets.

A dust collection box is installed inside the fixed box. A dust collection pipe is installed between the fixed box and the fan. A filter screen is installed at the inner end of the dust collection hood. During crushing, the flying dust is adsorbed by the working fan and enters the dust collection box through the dust collection pipe. This effectively reduces the diffusion of dust in the air, reduces dust pollution in the working environment, and protects the health of operators. The filter screen can intercept larger impurities in the dust, preventing them from entering the fan and dust collection pipe, avoiding damage to the equipment due to the accumulation of impurities, extending the service life of the equipment, and reducing secondary pollution of the environment by dust.

[0012] Preferably, the vibrating screening mechanism includes a fixed base, which is fixedly connected to the left and right ends inside the screening box. A spring column is fixedly connected inside the fixed base, and a pressure plate is fixedly connected to the surface of the spring column. A filter plate is inserted into the fixed base.

[0015] 1. This crushing device for plastic bottle processing is equipped with a plastic bottle crushing component. This component is designed with a double-layer crushing structure. The first crushing roller is rotated by a first servo motor, and the plastic bottle is crushed for the first time by the first crushing blade. Then, the crushed fragments fall into the secondary crushing chamber. Fragments of suitable size will fall through the inclined filter plate, while unsuitable fragments will be crushed for the second time by the second crushing roller driven by the second servo motor. This can realize the primary crushing and secondary fine crushing of plastic bottles, ensuring that the plastic bottles are fully crushed and reducing the residue of large particles. Through the shearing and impact action of the blades, the plastic bottles can be effectively crushed into smaller particles, improving the crushing quality.

[0016] 2. This crushing device for plastic bottle processing is equipped with a dust collection component. During crushing, the flying dust is adsorbed by the working fan and enters the dust collection box through the dust collection pipe, effectively reducing the spread of dust in the air, reducing dust pollution in the working environment, and protecting the health of operators. The filter screen can intercept larger impurities in the dust, preventing them from entering the fan and dust collection pipe, avoiding damage to the equipment due to the accumulation of impurities, extending the service life of the equipment, and reducing secondary pollution of the environment by dust.

[0028] Please see Figure 1-5 A crushing device for processing plastic bottles includes a crushing box 1, a feeding port 2 fixedly connected to the bottom of the crushing box 1, a dust removal box 3 fixedly connected to the bottom of the feeding port 2, a secondary crushing box 4 fixedly connected to the bottom of the dust removal box 3, a screening box 5 fixedly connected to the bottom of the secondary crushing box 4, a plastic bottle processing crushing mechanism 7 provided on the surface of the crushing box 1, the dust removal box 3 and the secondary crushing box 4, the plastic bottle processing crushing mechanism 7 including a plastic bottle crushing component 71 and a dust collection component 72, a vibrating screening mechanism 8 provided on the surface of the screening box 5, a feeding port 2 fixedly connected to the top of the crushing box 1, and bases 6 fixedly connected to the left and right ends of the screening box 5;

[0029] The plastic bottle crushing assembly 71 includes a first crushing roller 711, which is rotatably connected to the inside of the crushing chamber 1. A first crushing blade 712 is fixedly connected to the surface of the first crushing roller 711. A motor frame 713 is fixedly connected to the right end of the crushing chamber 1, and a first servo motor 714 is installed inside the motor frame 713. Inclined filter plates 715 are fixedly connected to the left and right ends inside the secondary crushing chamber 4. A second crushing roller 716 is rotatably connected inside the secondary crushing chamber 4, and a second crushing blade 717 is fixedly connected to the surface of the second crushing roller 716. A second servo motor 718 is installed on the back of the secondary crushing chamber 4. This assembly is designed as a double-layer crushing assembly. The structure controls the rotation of the first crushing roller 711 via the first servo motor 714, and the plastic bottle is crushed for the first time by the first crushing blade 712. Then, the crushed fragments fall into the secondary crushing chamber 4. Fragments of suitable size fall through the inclined filter plate 715, while unsuitable fragments are driven by the second servo motor 718 to rotate the second crushing roller 716 and be crushed for the second time by the second crushing blade 717. This structure can achieve both primary crushing and secondary fine crushing of plastic bottles, ensuring that the plastic bottles are fully crushed and reducing the residue of large particles. Through the shearing and impact action of the blades, the plastic bottles can be effectively crushed into smaller particles, improving the crushing quality.

[0030] The first crushing roller 711 is fixedly connected to the left output end of the first servo motor 714, and the second crushing roller 716 is fixedly connected to the front output end of the second servo motor 718;

[0031] The first crushing roller 711, the motor frame 713, the first servo motor 714, the inclined filter plate 715, the second crushing roller 716, and the second servo motor 718 are all provided in two sets.

[0032] The dust collection assembly 72 includes a dust collection hood 721, which is installed at both ends of the dust collection box 3.

A filter screen 726 is installed inside the dust collection hood 721. During crushing, the flying dust is adsorbed by the operation of the fan 722 and enters the dust collection box 724 through the dust collection pipe 725. This effectively reduces the spread of dust in the air, reduces dust pollution in the working environment, and protects the health of operators. The filter screen 726 can intercept larger impurities in the dust and prevent them from entering the fan 722 and the dust collection pipe 725, avoiding damage to the equipment due to the accumulation of impurities, extending the service life of the equipment, and reducing secondary pollution of the environment by dust.

[0034] Please see Figure 1-5Furthermore, based on Embodiment 1, the vibration screening mechanism 8 includes a fixed base 81, which is fixedly connected to the left and right ends inside the screening box 5. A spring column 82 is fixedly connected inside the fixed base 81, and a pressure plate 83 is fixedly connected to the surface of the spring column 82. A filter plate 84 is inserted into the fixed base 81. A rotating shaft 85 is rotatably connected inside the screening box 5. A fixed sleeve 87 is fixedly connected to the surface of the rotating shaft 85. An impact column 88 is fixedly connected to the surface of the fixed sleeve 87. A third servo motor 86 is installed on the back of the screening box 5, and an inspection door 89 is installed on the top front of the screening box 5.

[0035] The pressure plate 83 is fixedly connected to the end of the spring column 82 away from the fixed seat 81, the rotating shaft 85 is fixedly connected to the front output end of the third servo motor 86, and the outer end of the impact column 88 is in contact with the bottom end of the filter plate 84.

[0036] In actual operation, when this device is used, plastic bottles are added into the device through the feeding port 2. The plastic bottle crushing component 71 is designed with a double-layer crushing structure. The first crushing roller 711 is rotated by the first servo motor 714, and the plastic bottle is crushed for the first time by the first crushing blade 712. Then the crushed fragments fall into the secondary crushing chamber 4. Fragments of suitable size will fall through the inclined filter plate 715, while unsuitable fragments will be driven by the second servo motor 718 to rotate the second crushing roller 716 and be crushed for the second time by the second crushing blade 717. This can realize the primary crushing and secondary fine crushing of plastic bottles, ensuring that the plastic bottles are fully crushed and reducing the residue of large particles. Through the shearing and impact action of the blades, the plastic bottles can be effectively crushed into smaller particles, improving the crushing quality.

[0037] During crushing, the flying dust is adsorbed by the working of the fan 722 and enters the dust collection box 724 through the dust collection pipe 725, which effectively reduces the spread of dust in the air, reduces dust pollution in the working environment, and protects the health of operators. The filter screen 726 can intercept larger impurities in the dust and prevent them from entering the fan 722 and the dust collection pipe 725, avoiding damage to the equipment due to the accumulation of impurities, extending the service life of the equipment, and reducing secondary pollution of the environment by dust.

[0038] Next, the fragments will fall into the screening box 5. The rotating shaft 85 will be driven to rotate by the third servo motor 86. The impact column 88 will impact the filter plate 84, and the screening will be achieved through vibration. The spring column 82 is set to ensure the stability of the filter plate 84 and effectively prevent the filter plate 84 from being damaged by vibration. The screened fragments will be discharged from the bottom of the screening box 5. Later, the maintenance door 89 can be opened to collect and process the fragments on the surface of the filter plate 84.
