[0026] 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.

[0027] Example 1: Please refer to Figures 1-5 In existing film processing extrusion equipment, after the cleaning component has cleaned the extrusion equipment, it is not convenient to disassemble and maintain the cleaning component, which leads to repeated use of the cleaning component and incomplete cleaning, resulting in the extrusion equipment not being clean. In order to solve this technical problem, this embodiment discloses the following technical content.

[0028] The cleaning device 4 is composed of a first cover plate 401, a connecting block 402, a second cover plate 403, a limiting block 404, a motor 405, and a cleaning brush 406. The connecting block 402 is fixedly connected to the middle of the upper surface of the first cover plate 401. Both the first cover plate 401 and the connecting block 402 are circular plates. Both the first cover plate 401 and the connecting block 402 can be engaged with the hole opened in the middle of the top of the mounting frame 1. The second cover plate 403 is fixedly connected to the upper surface of the connecting block 402. The front and rear shafts of the connecting block 402 are slidably connected in the limiting block 404. The limiting blocks 404 are fixedly connected to the middle of the front and rear ends of the upper surface of the mounting frame 1. The motor 405 is fixedly connected to the middle of the lower surface of the first cover plate 401. The output shaft of the motor 405 is fixedly connected to the cleaning brush 406 by bolts. The outer side of the cleaning brush 406 is in contact with the inner side of the material box 2.

[0029] When the equipment is extruding film, the second cover plate 403 engages with the hole at the top of the mounting frame 1. At this time, the first cover plate 401, motor 405, and cleaning brush 406 are in the upper position. After the material in the material box 2 is extruded, the material box 2 and the extrusion tube 3 need to be cleaned. At this time, first pull the second connecting tube 10 away from the second cover plate 403, then lift the first cover plate 401 upwards, so that the connecting block 402 slides within the limiting block 404. When the connecting block 402 slides to the top of the limiting block 404, flip the first cover plate 401 and the second cover plate 406. 03. Flip the first cover plate 401, motor 405 and cleaning brush 406 to the bottom, and finally move the connecting block 402 downward so that the first cover plate 401 engages with the hole at the top of the mounting bracket 1. At this time, cleaning fluid can be added into the material box 2 and the motor 405 can be started. The output shaft of the motor 405 drives the cleaning brush 406 to rotate in the material box 2 to clean the material box 2. After the material box 2 is cleaned, stop adding cleaning fluid and stop running the motor 405. Since the shape of the extrusion tube 3 is irregular, the extrusion tube 3 can be removed for cleaning and maintenance.

[0030] Example 2: Existing film extrusion equipment has limitations. Different films require different thicknesses, making it inconvenient to change extruder heads and adjust the extrusion thickness. Furthermore, the cleaning solution used to clean the extrusion equipment is not easily recycled. Therefore, this example addresses these issues through the following technical solution: Figures 1-4 and Figure 6As shown;

[0031] The top center of the mounting frame 1 is fixedly connected to the material box 2, and the bottom of the material box 2 is fixedly connected to the extrusion tube 3 by bolts.

[0032] The discharge port at the bottom of the extrusion tube 3 is fixed. To extrude films of different sizes, the extrusion tube 3 needs to be removed and replaced. The bottom outer side of the material box 2 and the top outer side of the extrusion tube 3 are both fixedly connected to annular plates. The annular plates on the outer sides of the material box 2 and the extrusion tube 3 are fixed at equal angles by several stabilizing bolts. By removing the stabilizing bolts, the extrusion tube 3 can be separated from the material box 2. Since the bottom inner side of the material box 2 has a groove and the top inner side of the extrusion tube 3 is fixedly connected to a protrusion, when the material box 2 is connected to the extrusion tube 3, the protrusion on the extrusion tube 3 engages with the groove on the material box 2, which can prevent material from overflowing from the connection between the material box 2 and the extrusion tube 3. The above are the steps for disassembling and assembling the material box 2.

[0033] A water receiving trough 5 is provided directly below the extrusion tube 3, and universal wheels are fixedly connected to the four corners of the lower surface of the water receiving trough 5. The water receiving trough 5 and the top cover 8 are fixedly connected by the first connecting pipe 6. The top cover 8 is snapped onto the top of the collection box 7. A filter screen 9 is installed inside the collection box 7. A second connecting pipe 10 is fixedly connected to the middle of the bottom rear side of the collection box 7. The top of the second connecting pipe 10 is snapped onto the first cover plate 401 or the second cover plate 403. A water pump 11 is fixedly connected to the middle of the second connecting pipe 10.

[0034] Before cleaning, move the water receiving tank 5 directly below the extrusion pipe 3. The water receiving tank 5 can receive the cleaning liquid discharged from the extrusion pipe 3. The cleaning liquid collected in the water receiving tank 5 is discharged into the collection tank 7 through the first connecting pipe 6. After being filtered by the filter screen 9, the cleaning liquid can be reused multiple times. The filter screen 9 is placed on the annular plate set at the upper end of the inside of the collection tank 7. The filter screen 9 can be removed from the collection tank 7 for cleaning and maintenance. When the filtered cleaning liquid needs to be used, start the water pump 11. The water pump 11 draws the cleaning liquid upward through the second connecting pipe 10 and releases it from the top of the material box 2.

[0035] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
