Technical Field
[0001] This utility model relates to the field of PET plastic bottle recycling technology, specifically a PET plastic bottle recycling and crushing device. Background Technology
[0002] With the increasing use of plastic bottles, a large number of waste plastic bottles are generated. After recycling and cleaning, these plastic bottles are crushed. However, when workers use traditional plastic bottle crushing equipment, they often only process the bottles once, resulting in unsatisfactory processing. Sometimes, during the process, the generated plastic fragments fly everywhere, posing a safety hazard to workers and hindering widespread use. Therefore, we propose a PET plastic bottle recycling and crushing device to solve the problems mentioned in the background technology. Utility Model Content
[0003] The purpose of this invention is to provide a PET plastic bottle recycling and crushing device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a PET plastic bottle recycling and crushing device, comprising a pressing mechanism, a crushing cylinder, and a screening and reflux mechanism arranged sequentially from top to bottom and interconnected with each other. A movable base is fixedly installed at the bottom of the screening and reflux mechanism. A crushing motor is symmetrically installed on the front of the crushing cylinder. The output shaft of the crushing motor extends into the inside of the crushing cylinder. A rotating roller is fixedly connected to the surface of the output shaft of the crushing motor located inside the crushing cylinder. Several crushing blades are alternately installed on the two rotating rollers.
[0005] The pressing mechanism includes a pressing box, a feeding cylinder that is fixedly connected to the left side of the pressing box and communicates with it, a telescopic cylinder that is fixedly installed on the top of the pressing box, a pressing plate that is fixedly connected to the driving end of the telescopic cylinder extending into the pressing box, and a first material inlet that communicates with the crushing cylinder at the bottom of the pressing box, and a baffle that is slidably connected to the first material inlet laterally.
[0006] Furthermore, openings are provided on both the left and right sides of the pressure box, and a mounting shell is fixedly connected to the outer side of the pressure box at the position corresponding to the opening. A push plate is fixedly connected to the inner wall of the mounting shell by a cylinder.
[0007] Furthermore, an electric push rod is fixedly installed on the right side of the pressure box at the position corresponding to the baffle. The telescopic end of the electric push rod extends into the inside of the first feed port and is fixedly connected to the baffle. The left side of the baffle is inserted into the recess on the left side of the inner wall of the first feed port.
[0008] Furthermore, the screening and reflux mechanism includes a screening box and a reflux cylinder. The screening box is fixedly connected to the bottom of the crushing cylinder. A second feed port communicating with the crushing cylinder is opened at the top of the screening box. A screening screen is rotatably connected to the surface of a fixed shaft on the inner wall of the screening box. A collection box is provided at the bottom of the inner wall of the screening box. An access port is opened at the bottom of the right side of the screening box.
[0009] Furthermore, the reflux cylinder is fixedly connected to the left side of the screening box and is interconnected with it. A stepper motor is fixedly installed at the bottom of the reflux cylinder. The output shaft of the stepper motor extends into the reflux cylinder. A feeding auger is fixedly connected to the surface of the output shaft of the stepper motor located inside the reflux cylinder. A material passage pipe is fixedly installed on the top right side of the reflux cylinder and is interconnected with it. The material passage pipe passes through the crushing cylinder and extends above the two rotating rollers.
[0010] Furthermore, a vibration motor is fixedly installed on the support plate on the right side of the inner wall of the screening box, and the output end of the vibration motor is in contact with the bottom of the screening screen.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] This invention involves feeding PET plastic bottles into a pressing chamber via a feeding cylinder. After activating the telescopic cylinder, the pressing plate moves vertically downwards, compressing the plastic bottles to reduce their volume for easier subsequent shredding. Once compression is complete, an electric push rod moves a baffle horizontally to the right, and a cylinder drives a pusher plate to push the plastic bottles through the first feed inlet into the crushing cylinder. When the crushing motor is turned on, its output shaft drives a rotating roller, which crushes the plastic bottles using the crushing blades. The crushed material falls into a screening box, where a vibrating motor vibrates the screening screen, allowing smaller pieces to fall into a collection box. Inside, larger volumes of material slide into the return cylinder. After the stepper motor is turned on, its output shaft drives the feeding auger to rotate, conveying the material to the discharge pipe. The material is then crushed and screened by the crushing blades. By repeating the above steps, all the material can be cut into small fragments. This PET plastic bottle recycling and crushing device has a reasonable structural design and is easy to use. When recycling and crushing plastic bottles, it can achieve cyclic crushing processing, which has a good processing effect, can ensure the uniformity of the size of the cut fragments, and the entire crushing process is highly safe and has a good crushing effect, which is conducive to its widespread use.
