[0001] This utility model relates to the field of PE bag production technology, and in particular to a raw material mixing device for PE bag production. Background Technology

[0002] PE bags are commonly used in the packaging of clothing, bags, electronic products, etc. The raw materials used in the production of PE bags are composed of polyethylene granules of different components, which need to be thoroughly mixed and stirred.

[0003] For example, Chinese patent application CN202320046709.X discloses a raw material melting device for PE bag production. Its specific content is as follows: two cleaning components are symmetrically arranged on both sides of a rotating shaft. Two symmetrical grooves are opened on the rotating shaft. When the cleaning components are in operation, an electric slider moves from the rotating groove to the inside of the groove. Simultaneously, the electric slider controls the position of a telescopic column inside the groove, and the telescopic column drives the cleaning scraper to pop out, so that the cleaning scraper contacts the inner wall of the melting tank. The rotating shaft drives the cleaning components to rotate, thereby causing the cleaning scraper to clean and transfer the raw material adhering to the inner wall of the melting tank. This utility model cleans the raw material adhering to the inner wall of the melting tank during the raw material discharge process. However, it has the following technical problems:

[0004] When the rotating shaft drives the stirring rod to stir the raw materials, the groove on the stirring shaft is easily blocked by the raw materials, making it difficult for the cleaning component to move downwards, and the cleaning scraper to clean the residual raw materials on the inner wall of the lower end of the melting tank. Utility Model Content

[0005] To address the problem mentioned in the background art where the groove on the stirring shaft becomes clogged, making it difficult for the cleaning scraper to clean the residual raw materials on the inner wall of the lower end of the melting tank, this utility model provides the following technical solution:

Detailed Implementation

[0026] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0027] Please see Figures 1-5 This utility model provides a raw material mixing device for PE bag production, including a mixing tank 100. The mixing tank 100 includes a tank body 110. A feeding port 111 is fixedly installed on the upper left side of the tank body 110, and a discharge port 112 is fixedly installed on the middle of the lower end of the tank body 110. A valve is installed on the discharge port 112. Raw materials are fed into the tank body 110 through the feeding port 111 for mixing. After mixing is completed, the valve on the discharge port 112 is opened to discharge the raw materials from the tank body 110. A water tank 120 is fixedly installed on the middle of the upper end of the tank body 110, and a water inlet pipe 121 for supplying water into the water tank 120 is installed at one end of the water tank 120.

[0028] A stirring device 200 for stirring raw materials is installed in the middle of the box 110. The stirring device 200 includes a stirring rod 210. Multiple connecting rods 211 for stirring raw materials are fixedly installed on the lower outer wall of the stirring rod 210. A scraper 212 for cleaning the inner wall of the box 110 is installed at one end of the connecting rod 211. When cleaning the inner cavity of the box 110, the scraper 212 scrapes off the residual raw materials on the inner wall of the box 110, and the inner wall of the box 110 is cleaned with water.

[0029] The upper end of the stirring rod 210 has a central hole 213 machined in the middle. Multiple water inlets 214 are located at the upper end of the central hole 213 and are situated within the water tank 120. Multiple water outlets 215 are located at the lower end of the central hole 213. A valve is installed on the water inlet pipe 121. When the valve is opened, water is transported through the water inlet pipe 121 to the water tank 120. The water in the water tank 120 is then transported through the multiple water inlets 214 to the central hole 213, and then from the central hole 213 to the multiple water outlets 215. A motor 220 for controlling the rotation of the stirring rod 210 is installed at the upper end of the stirring rod 210, and the motor 220 is fixedly installed at the upper end of the water tank 120.

[0030] A limiting turntable 230 is fixedly installed at the upper end of the stirring rod 210. The limiting turntable 230 has multiple water passage holes 231 in the middle for communicating with the water outlet 215. An annular groove 232 is provided in the middle of the limiting turntable 230, and one end of the multiple water passage holes 231 is connected to the upper end of the annular groove 232. Water in the middle hole 213 is transported to the upper end of the inner cavity of the annular groove 232 through the multiple water outlets 215 and the water passage holes 231. Multiple water passage holes 233 are provided on the inner side of the annular groove 232 for water supply, and the water passage holes 233 are U-shaped cavities.

[0031] The lower end of the limiting turntable 230 is equipped with an annular spray plate 240 for cleaning the inner cavity of the housing 110. The annular spray plate 240 has multiple nozzles 241 in the middle. Multiple connecting pipes 242 are fixedly installed at the upper end of the annular spray plate 240. An annular piston 244 is fixedly installed at the upper end of the connecting pipe 242. Both the outer and inner walls of the annular piston 244 are equipped with sealing rings. The annular piston 244 slides in the annular groove 232 and divides the inner cavity of the annular groove 232 into an upper cavity and a lower cavity. Multiple water inlets 243 connected to the nozzles 241 are machined in the middle of the connecting pipe 242. A spring 245 for controlling the reset of the annular piston 244 is sleeved on the outside of the connecting pipe 242.

[0032] After the raw materials are mixed, open the valve on the discharge port 112 to discharge the raw materials from the tank 110. When cleaning the inner cavity of the tank 110, close the valve on the discharge port 112 and open the valve on the water inlet pipe 121, so that water is sequentially transported through the water inlet pipe 121, the water tank 120, and the first water inlet 214 to the central hole 213. The water in the central hole 213 is transported through multiple water outlets 215 and the first water passage hole 231 to the upper cavity of the annular groove 232. The water pressure pushes the annular piston 244 downward, causing the annular piston 244 to move downward. When the annular piston 244 moves to the second water passage hole 233... When the water is below the inlet, the annular piston 244 stops moving, and water is delivered to the lower cavity of the annular groove 232 through multiple water passages 233. Then, the water is sprayed onto the inner wall of the mixing box 100 through the inlet 243 and the nozzle 241. The stirring rod 210 is driven to rotate by the motor 220, and the limiting turntable 230 rotates synchronously. The connecting rod 211 drives the scraper 212 to clean the inner wall of the box 110. Finally, the valve on the outlet 112 is opened to discharge the sewage. During drainage, the annular spray plate 240 continuously sprays the inner wall of the box 110 to facilitate cleaning the inner wall of the box 110.

[0033] The bottom of the limiting turntable 230 is provided with an annular receiving groove for storing the annular spray plate 240. When the water supply stops, multiple springs 245 push the annular piston 244 upward, thereby driving the annular spray plate 240 to move into the annular receiving groove at the lower end of the limiting turntable 230, so as to avoid the splashed material from clogging the nozzle 241 when the material is stirred.

[0034] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
