[0031] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0032] like Figure 1 to Figure 2As shown, an embodiment of the utility model provides a stirring device for preparing a formable polyimide film, comprising: a stirrer body 1; a control console 2, which is arranged on the upper surface of the stirrer body 1 to control the rotation of a stirring roller 3; a stirring roller 3, which is arranged on the inner wall of a stirring barrel 4 to mix the raw materials; a stirring barrel 4, which is arranged on the upper surface of the stirrer body 1 to accommodate the filling of the raw materials; a discharge pipe 5, which is arranged on the surface of the stirring barrel 4, and the mixed raw materials are discharged through the discharge pipe 5; a motor 6, which is arranged at one end of the stirring roller 3 to drive the stirring roller 3 to rotate; a cleaning device 7, which is arranged on the surface of the stirring roller 3 to clean a large amount of raw materials remaining on the inner wall of the stirring barrel 4; a protective device 8, which is arranged on the surface of the control console 2 to protect the buttons and display screen on the surface of the control console 2.

[0033] like Figures 3 to 5As shown, the cleaning device 7 includes a support rod 701, the support rod 701 is fixedly connected to the stirring roller 3, one end of the support rod 701 is fixedly connected to a slider 702, a scraper 703 is detachably mounted on the surface of the slider 702, a slide groove 704 is provided on the surface of the scraper 703, and the size of the slide groove 704 is adapted to the size of the slider 702. When the raw materials for film preparation need to be mixed, the raw materials to be mixed are added to the stirring barrel 4, and then the motor 6 is started through the control console 2. The motor 6 drives the stirring roller 3 to rotate to mix the raw materials in the stirring barrel 4. After the raw materials in the stirring barrel 4 are mixed, the mixed raw materials flow out of the discharge pipe 5. The staff collects the materials, inserts the chute 704 on the scraper 703 into the slider 702 on the support rod 701, and then starts the motor 6 to drive the stirring roller 3 to rotate, and the stirring roller 3 will drive the scraper 703 to rotate, and the scraper 703 will scrape along the inner wall of the stirring barrel 4, and scrape off a large amount of residual raw materials adhering to the inner wall of the stirring barrel 4. The inner wall of the scraper 703 is provided with a fixed circular groove 711, and the fixed circular groove 711 is connected with the chute 704. The surface of the support rod 701 is provided with a movable groove 706, and the inner wall of the movable groove 706 is slidably connected with a movable plate 705, and the surface of the movable plate 705 is fixedly connected with a fixed pin 709. The size is adapted to the size of the fixed circular groove 711. The surface of the movable plate 705 is fixedly connected with a rubber pad 710. After the scraper 703 is inserted into the slider 702, the staff slides the movable plate 705 in the movable groove 706. The rubber pad 710 on the movable plate 705 makes it difficult for the staff's fingers to slip when pushing the movable plate 705 to move, so that the fixed pin 709 is inserted into the fixed circular groove 711. The fixed pin 709 fixes the scraper 703 to prevent the scraper 703 from shaking on the slider 702 when the scraper 703 is scraping the mixing barrel 4. The surface of the movable plate 705 is fixedly connected with a round rod 708, and the round rod 708 is connected to the support rod 706. 01 sliding connection, the arc surface of the round rod 708 is sleeved with a spring 707, one end of the spring 707 is fixedly connected to the movable plate 705, and the other end of the spring 707 is fixedly connected to the support rod 701, and the movable plate 705 is pushed by the spring 707 to make the fixed pin 709 stably inserted in the fixed circular groove 711. When the staff moves the movable plate 705, the spring 707 will be compressed, and the round rod 708 will limit the spring 707, so that the spring 707 is in a compressed state and is not easy to deform. The surface of the scraper 703 is fixedly connected with a guide block 712, and the guide block 712 is guided to facilitate the staff to insert the scraper 703 on the slider 702.

[0034] In an embodiment of the utility model, when it is necessary to mix the raw materials for preparing the film, the raw materials to be mixed are added to the stirring barrel 4, and then the motor 6 is started through the control console 2. The motor 6 drives the stirring roller 3 to rotate to mix the raw materials in the stirring barrel 4. After the raw materials in the stirring barrel 4 are mixed, the mixed raw materials flow out of the discharge pipe 5, and the staff collects them. The staff inserts the slide groove 704 on the scraper 703 into the slider 702 on the support rod 701, and then starts the motor 6 to drive the stirring roller 3 to rotate. The stirring roller 3 will drive the scraper 703 to rotate, and the scraper 703 will scrape along the inner wall of the stirring barrel 4, and scrape off a large amount of raw materials adhering to the inner wall of the stirring barrel 4. By setting a cleaning device 7, it is convenient for the staff to clean up later.

[0035] like Figure 6 to Figure 7 As shown, the protective device 8 includes a rotating frame 81, which is rotatably connected to the control console 2. The inner wall of the rotating frame 81 is fixedly connected with an acrylic plate 82. When the control console 2 is not needed to control the mixer body 1, the staff rotates the rotating frame 81 and covers the surface of the control console 2 with the acrylic plate 82. The acrylic plate 82 protects the buttons and display screen on the control console 2. A circular hole 83 is opened on the surface of the rotating frame 81. The inner wall of the control console 2 is threadedly connected with a screw rod 87. The size of the screw rod 87 is adapted to the size of the circular hole 83. One end of the screw rod 87 is fixedly connected with a screw piece. 86. When the acrylic plate 82 is covered on the surface of the console 2, the screw rod 87 is rotated by the screw piece 86 to rotate the screw rod 87 into the round hole 83, so that the rotating frame 81 can be fixed. The surface of the rotating frame 81 is fixedly connected with an elastic rope 84, and the other end of the elastic rope 84 is fixedly connected to the mixer body 1. The surface of the rotating frame 81 is fixedly connected with a limiting ring 85. When the acrylic plate 82 is not needed for protection, the elastic rope 84 contracts to drive the rotating frame 81 to rotate, so that the rotating frame 81 rotates automatically, and the limiting ring 85 will limit the elastic rope 84 to prevent the elastic rope 84 from being clamped by the moving frame.

[0036] In the embodiment of the utility model, when the control console 2 is not needed to control the mixer body 1, the staff rotates the rotating frame 81 and covers the surface of the control console 2 with the acrylic plate 82. By setting the protective device 8, the acrylic plate 82 will protect the buttons and display screen on the control console 2. The acrylic plate 82 is transparent, which also makes it convenient for the staff to view the contents on the display screen.

[0037] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
