[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0021] like Figure 1 - Figure 4 As shown, this application provides a multi-stage vortex mixing dynamic mixing device for wood-plastic composite raw materials, including: a support frame 1, a mixing cylinder 2 disposed inside the support frame 1, and an adjusting motor 3 connected to one end of the mixing cylinder 2; a top support plate 4 disposed at the top of the mixing cylinder 2; a multi-stage mixing adjusting component including a feeding box 5 and a transmission frame 19, the feeding box 5 being disposed at the top of the top support plate 4, a screw 6 disposed inside the feeding box 5, a feeding hopper 8 disposed at the top of the feeding box 5, and the transmission frame 19 being disposed at the bottom of the mixing cylinder 2; the multi-stage mixing adjusting component is used for multi-stage vortex mixing of wood-plastic composite raw materials; specifically, as shown... Figure 2 As shown, a movable slide frame 7 is slidably connected to the outside of the feed box 5, and the feed hopper 8 is set inside the movable slide frame 7. The movable slide frame 7 provides stability for the installation of the feed hopper 8, allowing the material to enter evenly.
[0022] Specifically, such as Figure 2 As shown, positioning frames 10 are connected to both sides of the top of the feed box 5, and telescopic baffles 9 are provided on the inner side of the positioning frames 10. The telescopic baffles 9 are easy to extend and retract, and are similar to springs, used for protection during feeding to prevent dust from spreading out.
[0023] Specifically, such as Figure 2 As shown, telescopic cylinders 11 are connected to both the front and rear ends of the feed box 5. The telescopic cylinders 11 are used to adjust the position of the sliding frame 7, so that the sliding frame 7 can drive the feed hopper 8 to adjust the position and allow the material to enter evenly.
[0024] Specifically, such as Figure 2 As shown, there are two feeding pipes 12 inside the bottom wall of the feeding box 5. The two feeding pipes 12 can make the material fall more evenly.
[0025] Specifically, such as Figure 1As shown, a discharge port 20 is provided at the bottom of one side of the conveyor frame 19. After the material is mixed in the mixing cylinder 2, it is further mixed and conveyed through the conveyor frame 19 and then discharged from the discharge port 20.
[0026] The scraper bonding assembly includes a rotating shaft 13, which is connected to both ends of the inner wall of the mixing cylinder 2. A connecting plate 15 is provided on the outer side of the rotating shaft 13, and a scraper 17 is provided on the outer side of the connecting plate 15. The scraper bonding assembly is used to bond to the inner wall during mixing.
[0027] Specifically, such as Figure 3 As shown, a mixing plate 14 is connected to the outer end of the rotating shaft 13. Multiple mixing plates 14 are provided for mixing materials in the middle.
[0028] Specifically, such as Figure 4 As shown, an elastic connecting rod 16 is connected inside the connecting plate 15, and a scraper 17 is connected to the outside of the elastic connecting rod 16. A soft pad 18 is connected to the outside of the scraper 17. The scraper 17 is connected to the outside of the connecting plate 15 through the elastic connecting rod 16, so that the scraper 17 fits against the inner wall of the mixing cylinder 2, which facilitates the full mixing of materials. The soft pad 18 on the inner side avoids scratching the inner wall of the mixing cylinder 2.
[0029] In this embodiment: the wood-plastic raw materials undergo multi-stage vortex mixing during mixing through the screw 6 inside the feed box 5, the moving feed hopper 8, the thorough mixing of the mixing cylinder 2, and the mixing and conveying discharge of the conveyor frame 19, thereby increasing the mixing rate. The mixing plate 14 and the connecting plate 15 are set up for synchronous mixing adjustment. The mixing plate 14 and the connecting plate 15 have different lengths and are used to mix the inner and outer sides respectively, so that the materials are thoroughly mixed inside and out. The scraper 17 connected to the connecting plate 15 fits against the mixing cylinder 2 to improve the thoroughness of material mixing.
[0030] Specifically, the solution is as follows: When mixing wood-plastic raw materials, the prepared raw materials are poured into the feeding box 5 through the feeding hopper 8. During the pouring process, the telescopic cylinder 11 drives the moving slide frame 7 to move, allowing the material from the feeding hopper 8 to fall at different positions inside the feeding box 5. Then, through the mutual rotation of the screw 6, the material is initially mixed. It is then fed into the mixing cylinder 2 through two feeding pipes 12. At this time, the rotating shaft 13 rotates, driving the mixing plate 14 and the connecting plate 15 to perform synchronous mixing adjustment. The mixing plate 14 and the connecting plate 15 have different lengths, which are used to mix the inner and outer sides respectively, so that the material is fully mixed inside and out. The scraper 17 connected to the connecting plate 15 fits against the mixing cylinder 2, and the outer side is provided with a soft pad 18 to avoid scratching, thereby improving the fullness of mixing. Then, the material falls from the bottom of the mixing cylinder 2 into the transmission frame 19, and is further mixed and transmitted through the transmission frame 19, and then discharged from the discharge port 20 to enter the next processing equipment.
[0031] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in the details for the sake of brevity.
[0032] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
