[0002] PVC membrane is a material made of polyvinyl chloride resin and other modifiers through calendering or blow molding. PVC membrane has good heat insulation, light transmission and flexibility, making it suitable as an outer covering material for greenhouses, sheds and other structures. PVC membrane is widely used in many industries such as building materials, packaging and pharmaceuticals.

[0003] The main component of PVC film is polyvinyl chloride. Plasticizers, stabilizers, lubricants and other functional processing aids are usually added to improve its performance. These auxiliary materials need to be mixed by a mixing device. Traditional mixing devices have fixed top hoppers that cannot be rotated or have their feeding angle adjusted. When the raw material points that need to be fed cannot be directly connected to the conduit, it is inconvenient to adjust the angle to facilitate the pipeline connection. At the same time, other auxiliary materials are added manually, which also affects the mixing efficiency. Summary of the Invention

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] A mixing device for raw and auxiliary materials in PVC film preparation includes a mixing tank 1 and a feeding mechanism 2. The feeding mechanism 2 is located on the top side of the mixing tank 1. The feeding mechanism 2 consists of a base 3, a rotating base 6, a supporting vertical plate 7, and a feeding rack 8. One end of the base 3 is movably connected to the outer wall of the mixing tank 1 via a rotating rod. The rotating base 6 is movably mounted on the top of the base 3. The top of the rotating base 6 is connected to the supporting vertical plate 7 via a supporting rod. A displacement groove is formed on the outer side of the supporting vertical plate 7. The feeding rack 8 is slidably mounted inside the displacement groove via a slider. The bottom of the container is provided with a box frame 14, and the top of the box frame 14 is provided with two material boxes 9. The top end of the feeding frame 8 is provided with a feeding hopper 10. The bottom side of the feeding frame 8 is provided with a guide pipe 11 that communicates with the feeding hopper 10. The bottom end of the guide pipe 11 is provided with a distributing seat 12. The top of the distributing seat 12 is connected to the bottom end of the guide pipe 11 by a thread. In this way, it is convenient to clean when the distributing seat 12 and the distributing pipe head 17 are blocked. The mixing tank 1 of this application has a mixing rod body driven by a motor inside, which can mix materials through the mixing rod body.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the present invention relates to a special raw and auxiliary material mixing device for PVC film preparation. Specifically, the bottom of the distributing seat 12 is provided with multiple distributing pipe heads 17 facing different directions. The ends of the distributing pipe heads 17 are fitted with flexible hoses 18. Multiple distributing pipe heads 17 are provided and are arranged in different directions. In this way, the material can be discharged to different positions of the mixing tank 1 to achieve uniform feeding. When the feeding mechanism 2 is rotated to the outside, the distributing pipe heads 17 are not placed inside the mixing tank 1. The material of the distributing pipe heads 17 can be introduced into the mixing tank 1 through the flexible hoses 18.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention relates to a special raw and auxiliary material mixing device for PVC film preparation. Specifically, a lifting cylinder 13 is installed at the bottom of the supporting vertical plate 7. The output end of the lifting cylinder 13 is connected to the slider inside the displacement groove. The lifting cylinder 13 of this application is a prior art cylinder structure. Powered by an external power source, the lifting cylinder 13 can push the feeding rack 8 to rise and fall, thereby adjusting the height of the feeding rack 8.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model relates to a special raw and auxiliary material mixing device for PVC film preparation. Specifically, two material bins 9 are provided with feeding pipes 15 on both sides, and one end of each feeding pipe 15 is connected to the two material bins 9 respectively. The other end of the feeding pipe 15 is connected to the top of the guide pipe 11. This application provides two material bins 9, and multiple material bins 9 can be selectively provided as needed. The material bins 9 are fed through the feeding pipes 15. Valves are provided at the top of the guide pipe 11 and at one end of the feeding pipe 15, which can be manually opened and closed to switch the flow channel of the material. When feeding, the corresponding valve is opened, and the auxiliary material is fed through the feeding hopper 10, filtered through the filter screen, and then directly flows into the material bin 9 through the feeding pipe 15.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model is a special raw and auxiliary material mixing device for PVC film preparation. Specifically, the inside of the feeding hopper 10 is equipped with a filter screen, and the bottom discharge port of the material box 9 is connected to a discharge pipe 16. One end of the discharge pipe 16 is connected to the guide pipe 11. The external raw materials and auxiliary materials can be directly filtered through the filter screen to remove impurities. An electromagnetic valve is installed at the discharge pipe 16. When the electromagnetic valve is opened, the auxiliary materials inside the material box 9 can be put into the guide pipe 11 through the discharge pipe 16.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model relates to a mixing device for raw and auxiliary materials for PVC film preparation. Specifically, the top of the rotating base 6 is provided with a ring of evenly distributed positioning holes. The side of the rotating base 6 is provided with a fixing arm 4. The top of the fixing arm 4 is threadedly connected to a locking screw, and the bottom end of the locking screw is threadedly connected to the inside of the positioning hole. The bottom side of the base 3 is threadedly connected to a second locking screw 5. Multiple positioning holes are provided on the top outer surface of the mixing tank 1. One end of the second locking screw 5 is threadedly connected to the inside of the positioning hole. The above structure is mainly used to limit the position of the base 3 and the rotating base 6. After the angle of the base 3 and the rotating base 6 is adjusted, the position can be limited by the first locking screw and the second locking screw 5.

[0026] During processing, the feeding mechanism 2 is installed on top of the mixing tank 1. When the feeding hopper 10 is at the top of the mixing tank 1, and the raw material feeding point can be directly connected to the feeding hopper 10, the external pipe can be directly connected to the feeding hopper 10. During connection, it can be directly fitted onto the outside of the feeding hopper 10 and then tightened. Alternatively, the raw material discharge pipe can be fixed at the top of the feeding hopper 10, allowing the raw material to be directly discharged. After being filtered through the filter screen, it sequentially passes through the guide pipe 11, the distribution seat 12, and the distribution pipe head 17 before being discharged into the mixing tank 1 for mixing. When the raw material feeding point needs to be adjusted and cannot be directly connected to the feeding hopper 10, this application... The bottom of the material feeding mechanism 2 is equipped with a rotating base 6. By rotating the rotating base 6, the feeding hopper 10 can be moved closer to the discharge pipe point of the raw material. The base 3 can be rotated further to adjust the tilt angle of the feeding hopper 10. The lifting cylinder 13 pushes the feeding frame 8 to slide, thereby adjusting the feeding height, which facilitates the feeding of raw materials. The raw materials are introduced into the mixing tank 1 through the distributing pipe head 17 and the hose 18. At the same time, when adding auxiliary materials, the auxiliary materials can be directly discharged through the material box 9. In this way, the addition of auxiliary materials is also more efficient. The mixing device of this application can greatly improve the overall efficiency of adding raw and auxiliary materials.
