Description

Technical Field

[0001] The utility model relates to the technical field of adhesive film production equipment, in particular to an adhesive film mixing and stirring box device. Background Art

[0002] At present, the photovoltaic film industry generally uses conical mixers for production and batching. This is mainly because the traditional horizontal ribbon mixer has a serious residual dead zone problem when unloading materials. Mixing between batches can easily cause large errors in the mixing ratio, thus affecting the product quality of the finished photovoltaic film. Therefore, the industry currently generally uses column mixers for mixing and stirring. However, conical mixers have low stirring efficiency and a stirring dead zone problem at the bottom of the cone, and the stirring dead zone at the bottom of the cone needs to be secondary treated, which further reduces the stirring efficiency of the conical mixer. In addition, uneven photovoltaic film batching can easily lead to problems with photovoltaic film products.

[0003] At the same time, how to prevent the adhesive film from easily getting on the stirring mechanism or inside the mixing chamber, how to clean the residual adhesive film, and thus reduce the impact of the residual adhesive on the finished product are also issues that need to be solved.

[0023] The utility model provides a film mixing and stirring box device, such as Figure 1-4 As shown, it includes a bottom plate 1, on which a mixing barrel 2 is placed, and the mixing barrel 2 is connected with a feed port 3, a feed port 4, and a discharge port 5, and the mixing barrel 2 is covered with a barrel cover 6, on which a motor 7 is arranged, and the output end of the motor 7 is connected to a turntable 8, on which a plurality of stirring shafts 9 are axially arranged, and on which a stirring impeller 10 is arranged, and the device also includes a support plate 11, and the support plate 11 is vertically arranged on the bottom plate 1 beside the mixing barrel 2, and a slider 12 is slidably connected to the support plate 11, and the slider 12 is connected to the barrel cover 6, and a driving mechanism is also arranged on the support plate 11, and the barrel cover 6 is raised and lowered on the mixing barrel 2 under the action of the driving mechanism. The material is added from the feeding port 3 of the glue-bound raw material bin to the mixing barrel 2, and the additive is added from the feeding port 4 to the mixing barrel 2. After the mixing is completed, the material is discharged from the discharge port 5 for further production process. Correspondingly, the feeding port 3, the feeding port 4 and the discharge port 5 can be provided with valve bodies for controlling the input and output of materials.

[0024] Preferably, there are two stirring shafts 9, which are arranged on opposite sides at the lower end of the turntable 8. The stirring impellers 10 arranged on the stirring shafts 9 have opposite rotation directions. The impellers 10 with different rotation directions make the two impellers 10 have different extrusion directions for the mixed material, one extruding upward and the other extruding downward, thereby increasing the convection of the mixed material in the mixing barrel 2 and improving the uniformity of the mixed ingredients.

[0025] In the embodiment, Figure 1 As shown, a sliding frame 13 is provided on the support plate 11, and the slider 12 is slidably connected to the sliding frame 13. The driving mechanism includes a second motor 14 and a screw 15. The second motor 14 is arranged at the top of the support plate 11, and the screw 15 is vertically pivoted at the center of the sliding frame 13. The output end of the second motor 14 is connected to the screw 15, and the slider 12 is meshed with the screw 15. The screw 15 is driven to rotate by the second motor 14, thereby driving the slider 12 to rise and fall.

[0026] Furthermore, in order to prevent the inner wall of the mixing barrel 2 from being too attached to the wall, a plurality of fixing rods 16 are provided at the lower end of the turntable 8 , and slots 17 are provided on the fixing rods 16 , and scraping rods 18 are inserted into the slots 17 .

[0027] In the above embodiment, the scraper rod 18 is detachably fixed to the fixing rod 16. As shown in Figures 3 and 4, a screw hole is provided on the side of the fixing rod 16. A bolt is engaged in the screw hole to fix the scraper rod 18, making it easy to remove the scraper rod 18.

[0028] Further, such as Figure 2 In order to ensure the sealing of the connection between the barrel cover 6 and the mixing barrel 2, a flange 19 is provided at the upper end of the mixing barrel 2 and the lower end of the barrel cover 6. A circular groove 20 is provided on the flange 19 of the mixing barrel 2, and a corresponding circular ring 21 is provided on the flange 19 of the barrel cover 6. After the barrel cover 6 is closed on the mixing barrel 2, the circular ring 21 is adapted in the circular groove 20. In an embodiment, a sealing ring such as rubber can also be provided on the circular groove 20 or the circular ring 21 to improve the corresponding sealing.

[0029] Working principle: When the film mixing and stirring box device is used, Figure 1 As shown, the film raw material and the additive enter the mixing barrel 2 through the feed port 3 and the feed port 4 respectively. At this time, the barrel cover 6 is closed on the mixing barrel 2, and the motor 7 is started. The motor 7 drives the turntable 8 to rotate, and then drives the multiple stirring shafts 9 to stir in the mixing barrel 2, and also drives the scraper to scrape the inner wall of the mixing barrel 2. With the cooperation of the multiple scrapers and the stirring shafts 9, the mixed materials are fully stirred in the mixing barrel 2. After the mixed materials are stirred, the mixed materials are discharged from the discharge port 5 and enter the next process;

[0030] When the stirring shaft 9 needs to be cleaned or maintained, the motor 14 is started to drive the screw 15 to rotate, thereby driving the slider 12 to rise, and the barrel cover 6 to rise. Figure 2 and 3 As shown, the stirring shaft 9, the impeller 10, and the scraper can be cleaned or maintained, and the interior of the mixing barrel 2 can also be cleaned conveniently.

[0031] In summary, the film mixing and stirring box device is provided with multiple stirring shafts 9 on the turntable 8, and the impeller 10 is provided on the stirring shaft 9. Under the drive of the motor 7, the turntable 8 rotates to drive the multiple stirring shafts 9 to fully mix and stir the film and the additives in the mixing barrel 2, so as to make the film ingredients more uniform and improve the quality of the finished film; a fixed rod 16 is provided under the turntable 8, and a scraper rod 18 is inserted on the fixed rod 16. When the turntable 8 rotates, the inner wall of the mixing barrel 2 is scraped to prevent the glue mixed material from hanging too much on the wall and improve the fluidity of the mixed material; the barrel cover 6 can be raised and lowered with the slider 12 on the support plate 11, so that the stirring shaft 9 and the impeller 10 can be cleaned conveniently and the influence of residual glue on product quality can be reduced.
