[0026] As Figures 1 - 8 shown, the crushing device includes a crushing assembly 201. A feeding port 202 is fixedly installed at the top of the crushing assembly 201. A crushing shaft 206 is rotatably installed inside the crushing assembly 201. Crushing blades 208 are fixedly installed on the crushing shaft 206. Fixed blades 207 are fixedly installed on both sides of the crushing blades 208, and the fixed blades 207 are fixedly installed on the inner wall of the crushing assembly 201. A synchronous pulley II 205 is fixedly installed at one end of the crushing shaft 206.

A main bevel gear 209 is fixedly installed at the other end of the crushing shaft 206. A fine crushing mechanism is arranged below the crushing blades 208.

[0027] As Figures 1 - 8 shown, a transmission shaft fixing bracket 210 is fixedly installed on the crushing assembly 201. A transmission shaft 211 is rotatably installed on the transmission shaft fixing bracket 210. A side bevel gear 212 is fixedly installed at one end of the transmission shaft 211. The side bevel gear 212 meshes with the main bevel gear 209. A synchronous bevel gear 213 is fixedly installed at the other end of the transmission shaft 211.

[0028] As Figure 7 , Figure 8 shown, the fine crushing mechanism includes an inclined plate 217 fixedly installed inside the crushing component 201.

A plurality of crushing bumps 227 are fixedly arranged inside the inclined plate 217.

[0029] When the driven rotating shaft 104 rotates, the driven rotating shaft 104 drives the synchronous pulley I 203 to rotate. The synchronous pulley I 203 drives the synchronous pulley II 205 to rotate through the synchronous belt 204, thereby realizing the rotation of the crushing shaft 206. When the crushing shaft 206 rotates, the crushing blade 208 rotates, thereby realizing the preliminary recycling of the waste. While the crushing shaft 206 rotates, the main bevel gear 209 rotates. The main bevel gear 209 drives the side bevel gear 212 to rotate, thereby driving the transmission shaft 211 to rotate. When the transmission shaft 211 rotates, it drives the synchronous bevel gear 213 to rotate. The synchronous bevel gear 213 drives the transmission bevel gear 216 to rotate, thereby realizing the rotation of the connecting shaft 215. When the connecting shaft 215 rotates, it drives the rotating disc 229 to rotate; thereby completing the left and right shaking of the connecting rod 230; After the waste is crushed for the first time and falls into the inclined plate 217, by starting the second motor 218, the second motor 218 drives the crushing roller I 219 to rotate. While the crushing roller I 219 rotates, the large gear 221 rotates. The large gear 221 drives the small gear 222 to rotate. The small gear 222 drives the crushing roller II 220 to rotate, thereby performing a more refined crushing treatment on the waste. After the crushing is completed, the second motor 218 is reversed. The second motor 218 drives the sliding rack 225 to slide towards the small gear 222. The sliding rack 225 rotates and thereby drives the missing gear 223 to rotate, thereby opening the baffle 228 to allow the waste to enter the cleaning mechanism.

[0030] As Figures 1 - 11As shown in the figure, the cleaning mechanism includes a cleaning pool 301. Vibration plate support frames 304 are arranged on both sides of the cleaning pool 301. A vibration plate 303 is slidably mounted on the vibration plate support frames 304. A lifting rod 302 is fixedly installed in front of the cleaning pool 301. A third motor 305 is fixedly installed on the lifting rod 302. A cleaning rod is rotatably installed at the movable end of the third motor 305. A cleaning frame 306 is arranged on the cleaning rod.

[0031] The vibration plate 303 is shaken left and right through a connecting rod 230, so as to achieve a comprehensive cleaning treatment of the crushed waste. After cleaning, by raising the lifting rod 302, the cleaning frame 306 is lifted away from the cleaning pool 301. Subsequently, the cleaning frame 306 is moved to one side away from the cleaning pool 301 for collection treatment through the third motor 305.

[0032] The working principle of a plastic film production waste recycling device disclosed in the present invention is as follows: The waste produced by plastic film production is sequentially placed on a feeding table 101. By starting a first motor 102, the first motor 102 drives a feeding main shaft 103 to rotate. The feeding main shaft 103 drives a driven rotating shaft 104 to rotate through a conveyor belt 105, thereby completing the transportation of the waste.

[0033] When the driven rotating shaft 104 rotates, the driven rotating shaft 104 drives the synchronous pulley Ⅰ 203 to rotate. The synchronous pulley Ⅰ 203 drives the synchronous pulley Ⅱ 205 to rotate through the synchronous belt 204, so as to realize the rotation of the crushing shaft 206. The rotation of the crushing shaft 206 means the rotation of the crushing blade 208, thus realizing the preliminary recovery of the waste material. After the waste material is crushed once, it falls into the inclined plate 217. By starting the second motor 218, the second motor 218 drives the crushing roller Ⅰ 219 to rotate. While the crushing roller Ⅰ 219 rotates, the large gear 221 rotates. The large gear 221 drives the small gear 222 to rotate, and the small gear 222 drives the crushing roller Ⅱ 220 to rotate, so as to carry out a more refined crushing treatment on the waste material. After the crushing is completed, reverse the second motor 218. The second motor 218 drives the sliding rack 225 to slide towards the small gear 222. The sliding rack 225 rotates and drives the missing gear 223 to rotate, so as to open the baffle plate 228 and let the waste material enter the cleaning mechanism. At the same time, the rotation of the crushing shaft 206 drives the main bevel gear 209 to rotate. The main bevel gear 209 drives the side bevel gear 212 to rotate, so as to drive the transmission shaft 211 to rotate. The rotation of the transmission shaft 211 drives the synchronous bevel gear 213 to rotate. The synchronous bevel gear 213 drives the transmission bevel gear 216 to rotate, so as to realize the rotation of the connecting shaft 215. The rotation of the connecting shaft 215 drives the rotating disc 229 to rotate; thus, the left and right shaking of the connecting rod 230 is completed, so as to achieve a comprehensive cleaning treatment of the crushed waste material. After the cleaning, by raising the lifting rod 302, the cleaning frame 306 is lifted away from the cleaning pool 301. Subsequently, the third motor 305 moves the cleaning frame 306 to one side far away from the cleaning pool 301 for collection and treatment.

[0034] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope of the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
