DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the application will be described below with reference to the accompanying drawings.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the application clearer, the technical solutions in the embodiments of the application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some but not all of the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the application.

[0024] Please refer to Figure 1 The application provides a plastic film extruder, which comprises an extruder body 100 and a feeding assembly 200 connected with the extruder body 100.

[0025] Please refer to Figures 1-6 The feeding assembly 200 comprises a feeding pipe 210, a motor 220, a rotary connection sleeve 230, a connection rod 240, and a scraping rod 250. The bottom end of the feeding pipe 210 is fixedly connected with the feeding port of the extruder body 100. The motor 220 is connected with the feeding pipe 210. The outer wall of the feeding pipe 210 is fixedly provided with a connection plate 211. The motor 220 is connected to the upper surface of the connection plate 211. The body of the motor 220 is provided with a frame 221, which is fixedly connected to the upper surface of the connection plate 211.

[0026] In the specific arrangement, the rotary connection sleeve 230 is rotatably sleeved at the top end of the feeding pipe 210. The rotary connection sleeve 230 is in transmission connection with the rotary end of the motor 220. The rotary end of the motor 220 is provided with a bevel gear 222. The lower surface of the rotary connection sleeve 230 is provided with a bevel gear ring 231, which is rotatably sleeved outside the feeding pipe 210. The bevel gear ring 231 is in engagement with the bevel gear 222.

[0027] In this application, the connecting rod 240 is connected to the rotating connecting sleeve 230. One end of the connecting rod 240 is rotatably penetrated by a first bolt 241. The first bolt 241 can also slide through the rod body of the connecting rod 240. The first bolt 241 can slide and rotate inside the connecting rod 240. The bottom end of the first bolt 241 is threaded into the inside of the rotating connecting sleeve 230. A first positioning rod 232 is provided on the upper surface of the rotating connecting sleeve 230. One end of the connecting rod 240 is slidably sleeved on the rod body of the first positioning rod 232.

[0028] In this embodiment, the top end of the scraper 250 is connected to the connecting rod 240. The end of the connecting rod 240 away from the first bolt 241 is rotatably connected to the second bolt 242. The second bolt 242 can also slide through the rod body of the connecting rod 240. The bottom end of the second bolt 242 is threaded into the inside of the top end of the scraper 250. The top end of the scraper 250 is provided with a second positioning rod 251. The end of the connecting rod 240 away from the first bolt 241 is slidably sleeved on the rod body of the second positioning rod 251. The scraper 250 rotates inside the feed pipe 210 and is in contact with the inner wall of the feed pipe 210.

[0029] Specifically, the working principle of this plastic film extruder is as follows: During use, plastic raw materials are added into the feed pipe 210. The raw materials enter the extruder body 100 through the feed pipe 210. During feeding, the motor 220 is turned on, which drives the rotating connecting sleeve 230 to rotate, thereby driving the connecting rod 240 to rotate, and then driving the scraper 250 to rotate. The scraper 250 rotates along the inner wall of the feed pipe 210, thus preventing the raw materials from adhering to the inner wall of the feed pipe 210 and preventing blockage inside the feed pipe 210. This ensures feeding efficiency and avoids manual unblocking, making it highly practical.
