[0002] PET plastic bottles, used for beverage packaging, are widely used not only for carbonated drinks, drinking water, juice, enzyme drinks, and tea beverages, making them the most widely used beverage packaging today, but also for food, chemical, and pharmaceutical packaging. PET plastic has extensive applications in the packaging industry, used in both packaging films and roll materials. However, the disposal of these materials after they are discarded raises the question of how to handle them. China produces tens of billions of PET plastic bottles annually, and it is estimated that by 2005, more than 500,000 tons of PET would be used annually in the manufacture of PET plastic bottles.

[0003] In the process of plastic bottle production and recycling, most existing recycling devices suffer from problems such as incomplete crushing, poor sorting effect, and low degree of automation, which cannot meet the needs of efficient and accurate recycling of plastic bottle waste.

A crushing and sorting component is provided on one side of the feeding bin. The crushing and sorting component includes a protective shell installed inside the feeding bin. A servo motor is installed inside the protective shell. A crushing cover is provided on one side of the servo motor. A first crushing roller and a second crushing roller are rotatably connected inside the crushing cover. The output end of the servo motor is fixedly connected to one end of the first crushing roller. Rotating gears are fixedly connected to the other ends of both the first and second crushing rollers, and the rotating gears mesh with each other.

[0005] Furthermore, a drive wheel is fixedly connected to the outer surface of the other end of the second crushing roller, and a mounting bracket is fixedly connected to the outer surface of the crushing cover.

[0006] Furthermore, an extension rod is rotatably connected to the outer surface of the mounting bracket, and a driven wheel is fixedly connected to the outer surface of the extension rod. The driven wheel and the driving wheel are connected by a belt drive, and a cam is fixedly connected to one end of the extension rod.

[0007] Furthermore, a filter plate is hinged to the bottom surface of the crushing hood via a hinge, and two support frames are fixedly connected to the outer surface of the crushing hood, with the outer surfaces of the support frames in contact with the outer surfaces of the filter plate.

[0008] Furthermore, a set of fans is installed on the inner wall of the crushing hood, and an electromagnetic plate is installed on the other inner wall of the crushing hood.

[0009] Furthermore, a set of bent rods is fixedly connected to the outer surface of the crushing hood, and guide plates are installed between the bent rods.

[0010] Furthermore, the crushing and sorting component also includes a square opening on the outer surface of the discharge box, and the bottom surface of the guide plate is in contact with the interior of the square opening.

[0011] Furthermore, the crushing and sorting component also includes a material discharge port and a pick-up and drop-off port, both of which are located on the outer surface of the discharge box, and a guide block is installed between the material discharge port and the pick-up and drop-off port.

[0012] Furthermore, the crushing and sorting component also includes a forward and reverse motor and a discharge port. The forward and reverse motor is installed on the upper surface of the discharge box, and the output end of the forward and reverse motor is fixedly connected to an auger rod. The discharge port is opened on the outer surface of the discharge box.

[0013] Beneficial effects:

[0014] By combining the feeding box and the crushing and sorting components, secondary crushing of plastic bottle waste can be achieved, thus ensuring consistent crushing results. This not only improves the automation level of the device, but also, through the combined use of the fan and electromagnetic plate in the crushing and sorting components, the separation of metal impurities and plastic can be achieved, thus meeting the demand for efficient processing of plastic bottle waste.

[0015] Through the coordinated setup of a servo motor, a first crushing roller, a second crushing roller, a rotating gear, a driving wheel, a driven wheel, a cam, a filter plate, a support frame, a fan, an electromagnetic plate, a guide plate, a guide block, a forward and reverse motor, an auger rod, and a discharge port, the servo motor is started, driving the first crushing roller to rotate. The rotating gear meshes to synchronize the rotation of the first and second crushing rollers. Simultaneously, the extension rod and the driving wheel drive the cam to strike the filter plate. The fan and electromagnetic plate are activated, feeding the plastic residue into the crushing hood for further crushing. As the crushed material falls, the fan blows metal impurities towards the electromagnetic plate, where they are attracted. The plastic falls onto the support frame, where it is shaken and screened. Qualified plastic enters the discharge box via the guide plate. Unqualified material is collected at the guide block. Under continuous shaking from the support frame, after the guide block is placed into the discharge box, it enters the box via the guide plate. The forward and reverse motors are then activated, driving the auger rod to rotate and transport the unqualified material back to the crushing hood for secondary crushing, ensuring consistent processing quality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figure 1-5 As shown, a plastic bottle waste crushing, sorting and recycling device includes a feeding box 1. A crushing and sorting component 2 is provided on one side of the feeding box 1. The crushing and sorting component 2 includes a protective shell 201 installed inside the feeding box 1. A servo motor 202 is installed inside the protective shell 201. The protective shell 201 can achieve sealed protection for the servo motor 202, thereby ensuring the normal use of the servo motor 202 in the future.

[0024] A crushing hood 203 is provided on one side of the servo motor 202. A first crushing roller 204 and a second crushing roller 205 are rotatably connected inside the crushing hood 203. The output end of the servo motor 202 is fixedly connected to one end of the first crushing roller 204. The other ends of the first crushing roller 204 and the second crushing roller 205 are fixedly connected to rotating gears 206, and the rotating gears 206 mesh with each other. Through the power provided by the servo motor 202, and by utilizing the meshing between the rotating gears 206, the first crushing roller 204 and the second crushing roller 205 can be rotated synchronously, thereby achieving the crushing of the residue.

[0025] A drive wheel 207 is fixedly connected to the outer surface of the other end of the second crushing roller 205. A mounting frame 208 is fixedly connected to the outer surface of the crushing cover 203. An extension rod 209 is rotatably connected to the outer surface of the mounting frame 208. A driven wheel 210 is fixedly connected to the outer surface of the extension rod 209. The driven wheel 210 and the drive wheel 207 are connected by a belt 21. A cam 211 is fixedly connected to one end of the extension rod 209. The rotation of the connecting shaft of the second crushing roller 205 can realize the synchronous rotation of the extension rod 209, thereby realizing the rotation of the cam 211.

[0026] The bottom surface of the crushing hood 203 is hinged to a filter plate 212. Two support frames 213 are fixedly connected to the outer surface of the crushing hood 203, and the outer surface of the support frames 213 is in contact with the outer surface of the filter plate 212. The support frames 213 can support the filter plate 212, thereby ensuring the effectiveness of the filter plate 212.

[0027] A set of fans 214 is installed on the inner wall of the crushing hood 203, and an electromagnetic plate 215 is installed on the other inner wall of the crushing hood 203. Each fan 214 can be equipped with a 9V battery, thus ensuring the normal operation of the subsequent fans 214. At the same time, the electromagnetic plate 215 can adsorb metal, thereby achieving the classification of residual materials and impurities.

[0028] A set of bent rods 216 are fixedly connected to the outer surface of the crushing hood 203, and a guide plate 217 is installed between the bent rods 216 to guide the residual material after crushing, which facilitates subsequent secondary crushing.

[0029] The crushing and sorting component 2 also includes a square opening 218 on the outer surface of the discharge box 1, and the bottom surface of the guide plate 217 is in contact with the inside of the square opening 218. By utilizing the contact between them, the residual material after crushing can be guided and transported for easy processing in the next step.

[0030] The crushing and sorting component 2 also includes a material discharge port 219 and a pick-and-place port 220. Both the material discharge port 219 and the pick-and-place port 220 are located on the outer surface of the material discharge box 1. A guide block 221 is installed between the material discharge port 219 and the pick-and-place port 220. The material discharge port 219 can discharge the raw materials, and the pick-and-place port 220 can remove the guide block 221, which is convenient for subsequent staff to pick up materials. At the same time, the guide block 221 can guide the raw materials to a certain extent, thereby ensuring the normal processing of the raw materials in the future.

[0031] The crushing and sorting component 2 also includes a forward and reverse motor 222 and a discharge port 224. The forward and reverse motor 222 is installed on the upper surface of the feeding box 1. The output end of the forward and reverse motor 222 is fixedly connected to the auger rod 223. The discharge port 224 is opened on the outer surface of the feeding box 1. Through the operation of the forward and reverse motor 222, the auger rod 223 can be rotated, and the auger rod 223 can guide the crushed raw material to achieve the reprocessing of the crushed raw material.

[0032] As a technical optimization of this utility model, when processing plastic waste, the servo motor 202 is first started. The output end of the servo motor 202 drives the first crushing roller 204 to rotate. By utilizing the meshing between the rotating gears 206, the first crushing roller 204 and the second crushing roller 205 can rotate synchronously. While rotating, the transmission between the extension rod 209 and the drive wheel 207 enables the cam 211 to strike the filter plate 212, thereby shaking the filter plate 212. Then, the fan 214 and the electromagnetic plate 215 are switched on. Subsequently, the plastic waste to be processed is placed into the crushing chamber 203 to begin crushing. As the crushed plastic waste and impurities fall into the guide plate 217 inside the crushing chamber 203, the fan 214 blows the metal impurities toward the surface of the electromagnetic plate 215. Thus, the electromagnetic plate 215 can adsorb the metal, and the remaining crushed plastic will fall onto the surface of the filter plate 212. After the cam 211 strikes and shakes the filter plate 212, the qualified plastic can be screened first. Then, it is guided by the guide plate 217 and enters the inside of the discharge box 1. The staff only needs to collect it at the guide block 221 through the collection box. With the continuous shaking of the support frame 213, before the unqualified plastic residue comes down, the guide block 221 is put into the inside of the discharge box 1. The plastic residue is guided by the guide plate 217 again and enters the inside of the discharge box 1. Then, the forward and reverse motor 222 is started. The output end of the forward and reverse motor 222 drives the auger rod 223 to rotate, which can realize the conveying of the unqualified residue to the discharge port 224 for leakage. The leaked raw material will flow back into the crushing hood 203 for secondary crushing to ensure consistent raw material processing quality.
