Technical Field
[0001] This application relates to the field of electromagnetic interference (EMI) film production technology, and in particular to a raw material mixing device for producing EMI films. Background Technology
[0002] Electromagnetic interference shielding film is a special material used to shield electromagnetic waves. It is widely used in electronic equipment, communication equipment and other fields to reduce the impact of electromagnetic interference on the performance of the equipment. This film material is usually composed of a variety of polymers and conductive materials. Its preparation process requires extremely high precision in the uniform dispersion and mixing of materials, which directly affects the performance and shielding effect of the film.
[0003] In the existing production process of electromagnetic interference-resistant films, raw material mixing is a key step. In order to ensure that various raw materials can be fully mixed, a special raw material mixing tank is usually required. This mixing tank uses mechanical stirring to make the raw materials of different components evenly dispersed in the tank to form a homogeneous mixture.
[0004] However, existing raw material mixing tanks mostly use a single stirring blade for rotary stirring. Since the raw materials of the anti-electromagnetic interference membrane are prone to becoming sticky during the mixing process, a single stirring blade is difficult to achieve sufficient dispersion and mixing of the raw materials, resulting in low mixing efficiency, which in turn affects the uniformity of the membrane material and the performance of the final product. Therefore, this application provides a raw material mixing device for the production of anti-electromagnetic interference membranes. Utility Model Content
[0005] The purpose of this application is to provide a raw material mixing device for the production of anti-electromagnetic interference membranes, in order to solve the problem that it is difficult for a single stirring blade to achieve sufficient dispersion and mixing of raw materials, resulting in low mixing efficiency.
[0006] To achieve the above objectives, this application specifically adopts the following technical solution:
[0007] A raw material mixing device for the production of anti-electromagnetic interference film includes a mixing tank. A top cover is installed on the top of the mixing tank, and a feed inlet is opened through the top of the top cover. A support leg is fixedly connected to the bottom of the mixing tank. Three side blocks are rotatably connected through the bottom surface of the top cover. A stirring component is installed on the three side blocks. A reinforcing component is installed at the ends of the three side blocks that are far apart from each other. A discharge port is opened through the bottom of the mixing tank, and a discharge component is installed at the bottom end of the discharge port. A connecting wall is fixedly connected to the outer wall of the mixing tank, and a valve is fixedly connected to the discharge port.
[0008] By adopting the above technical solution, the raw materials for the production of anti-electromagnetic interference film are poured into the mixing tank through the feed inlet. Then, the stirring component is started to simply stir the raw materials inside the mixing tank. Secondly, the rotation of the three-sided block guides the operation of the reinforcing component, which greatly improves the stirring efficiency of the mixing device. This allows for better dispersion and mixing of the raw materials, effectively improving the mixing efficiency and making the uniformity of the anti-electromagnetic interference film material and the performance of the final product more perfect. After the stirring and mixing is completed, the valve can be opened to allow the mixed raw materials to enter the discharge component through the discharge outlet. Then, the discharge component is started to quickly transport the mixed raw materials out, ensuring that the raw materials remain mixed during transportation.
[0009] Furthermore, the stirring assembly includes a motor fixedly connected to the top of the top cover, the output end of the motor fixedly connected to the top of the three-sided block, a stirring rod fixedly connected to the center bottom surface of the three-sided block, and a plurality of stirring blades fixedly connected to the stirring rod.
[0010] By adopting the above technical solution, the rotation of the three-sided block will guide the bottom stirring rod to drive multiple stirring blades to rotate continuously inside the mixing tank, thereby simply stirring the raw materials inside the mixing tank.
[0011] Furthermore, the reinforcing component includes rotating rods rotatably connected to one end of the three-sided block, a connecting plate fixedly connected to the bottom end of the rotating rods, a stirring rod II fixedly connected to the bottom surface of one end of the connecting plate, and a plurality of stirring blades II fixedly connected to the stirring rod II.
[0012] By adopting the above technical solution, the rotation of the rotating rod will drive the connecting plate at the bottom to rotate around the rotating rod as the center, thereby driving multiple stirring blades to rotate and stir inside the mixing tank.
[0013] Furthermore, a main gear is fixedly connected to the bottom of the top cover, and a connecting rod is rotatably connected through each of the three side blocks. A driven gear one is fixedly connected to the top of the connecting rod, and the connecting rod meshes with the main gear. A driven gear two is fixedly connected to the bottom of the connecting rod, and a driven gear three is fixedly connected to the rotating rod. The driven gear two and the driven gear three mesh with each other.
[0014] By adopting the above technical solution, since the main gear is meshed with multiple driven gears, the multiple driven gears can rotate continuously during the movement of the three-sided block. Since driven gears two and three are also meshed with each other, as driven gear two rotates continuously, it will drive driven gear three to rotate as well, thereby driving the rotating rod to rotate continuously through driven gear three.
[0015] Furthermore, a scraper is fixedly connected to the bottom end of the stirring rod, and scraper blades are fixedly connected to both sides of the scraper.
[0016] By adopting the above technical solution, the raw materials at the bottom of the mixing tank can be stirred and scraped off through the cooperation of the scraper and the scraper blade, so as to prevent the raw materials from settling and sticking to the bottom of the mixing tank.
[0017] Furthermore, multiple heating wires are uniformly fixedly connected inside the connecting wall, and the multiple heating wires are located between the connecting wall and the mixing tank.
[0018] By adopting the above technical solution, starting multiple heating wires can ensure that the raw materials inside the mixing tank are always at a suitable temperature, so as to prevent the raw materials from sticking together and solidifying due to low temperature, which would affect the mixing efficiency.
[0019] Furthermore, the discharge assembly includes a fixed block fixedly connected to the bottom of the discharge port, a baffle fixedly connected inside the fixed block, a second motor fixedly connected to one side of the baffle, an auger rotatably connected to the other side of the baffle, and the output end of the second motor fixedly connected to one end of the auger.
[0020] By adopting the above technical solution, the mixed raw materials can be quickly transported out by the rotation of the auger, so that the raw materials can always remain mixed during the transportation process.
[0021] Furthermore, the surfaces of the main gear and driven gear one are provided with a waterproof layer, and the surfaces of driven gear two and driven gear three are also provided with a waterproof layer.
[0022] By adopting the above technical solution, the waterproof layer applied to the surfaces of the main gear, driven gear one, driven gear two, and driven gear three can effectively provide them with certain waterproof and rust-proof effects.
[0023] In summary, this application includes at least one of the following beneficial effects:
[0024] 1. This application includes a stirring component and a reinforcing component. Multiple stirring blades can perform simple stirring of the raw materials inside the mixing tank. While the three-sided block rotates, it also drives the reinforcing component to operate. Through the cooperation of the stirring component and the reinforcing component, the stirring efficiency of the mixing device can be greatly improved, thereby better dispersing and mixing the raw materials, effectively improving the mixing efficiency, and making the uniformity of the anti-electromagnetic interference membrane material and the performance of the final product more perfect.
[0025] 2. This application includes a scraper, a scraper blade, and heating wires. During the mixing process, when the stirring rod drives multiple stirring blades, the scraper blade and scraper blade work together to stir and scrape the raw materials at the bottom of the mixing tank, preventing the raw materials from settling and sticking to the bottom of the mixing tank. Furthermore, during the mixing process, multiple heating wires can be activated to continuously heat the inside of the mixing tank, ensuring that the raw materials inside are always at a suitable temperature, preventing the raw materials from sticking together and solidifying due to low temperature, which would affect the mixing efficiency.

[0032] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.
[0033] This application discloses a raw material mixing device for the production of anti-electromagnetic interference films.
[0034] Reference Figure 1 and Figure 2A raw material mixing device for the production of an anti-electromagnetic interference film includes a mixing tank 1, a top cover 2 installed on the top of the mixing tank 1, a feed inlet 3 extending through the top of the top cover 2, a support leg 4 fixedly connected to the bottom of the mixing tank 1, a three-sided block 5 rotatably connected through the bottom surface of the top cover 2, a stirring assembly installed on the three-sided block 5, and reinforcing components installed at the ends of the three-sided blocks 5 that are far apart from each other, a discharge port 6 extending through the bottom of the mixing tank 1, a discharge assembly installed at the bottom end of the discharge port 6, a connecting wall 21 fixedly connected to the outer wall of the mixing tank 1, a valve 23 fixedly connected to the discharge port 6, the stirring assembly including a motor 7 fixedly connected to the top of the top cover 2, the output end of the motor 7 fixedly connected to the top of the three-sided block 5, a stirring rod 8 fixedly connected to the center bottom surface of the three-sided block 5, a plurality of stirring blades 9 fixedly connected to the stirring rod 8, and a plurality of heating wires 22 uniformly fixedly connected inside the connecting wall 21, the plurality of heating wires 22 being located between the connecting wall 21 and the mixing tank 1.
[0035] In use, the raw materials for producing the anti-electromagnetic interference film are first poured into the mixing tank 1 through the feed inlet 3. Then, the motor 7 is started to drive the three-sided block 5 to rotate continuously. Guided by the rotation of the three-sided block 5, the bottom stirring rod 8 drives multiple stirring blades 9 to rotate continuously inside the mixing tank 1, thereby performing simple stirring of the raw materials inside the mixing tank 1. While the multiple stirring blades 9 are stirring the raw materials, the rotation of the three-sided block 5 also drives the reinforcing component at one end of the three-sided block 5 to rotate as well. Therefore, through the cooperation of the stirring component and the reinforcing component, the stirring efficiency of the mixing device can be greatly improved, thereby better stirring the raw materials. Sufficient dispersion and mixing effectively improve mixing efficiency, resulting in more uniform anti-electromagnetic interference film material and more perfect performance of the final product. In addition, during the stirring and mixing process, multiple heating wires 22 can be activated to continuously heat the inside of the mixing tank 1, so that the raw materials inside can always be kept at a suitable temperature, so as to prevent the raw materials from sticking together and solidifying due to low temperature, which would affect the mixing efficiency. After the stirring and mixing is completed, the valve 23 can be opened to allow the mixed raw materials to enter the discharge component through the discharge port 6. Then, the discharge component is activated to quickly transport the mixed raw materials out, so that the raw materials can always be kept in a mixed state during transportation.
[0036] Reference Figure 2 and Figure 3The reinforcing components include rotating rods 14 rotatably connected to one end of the three-sided blocks 5, a connecting plate 16 fixedly connected to the bottom end of the rotating rods 14, a stirring rod 17 fixedly connected to the bottom surface of one end of the connecting plate 16, a plurality of stirring blades 18 fixedly connected to the stirring rod 17, a main gear 10 fixedly connected to the bottom of the top cover 2, a connecting rod 11 rotatably connected through each of the three-sided blocks 5, a driven gear 12 fixedly connected to the top end of the connecting rod 11, the connecting rod 11 meshing with the main gear 10, a driven gear 13 fixedly connected to the bottom end of the connecting rod 11, a driven gear 15 fixedly connected to the rotating rod 14, and a driven gear 13 meshing with the driven gear 15.
[0037] In use, as the triangular block 5 rotates continuously, it drives multiple driven gears 12 to move along with it. Because the main gear 10 meshes with the driven gears 12, the movement of the triangular block 5 causes the driven gears 12 to continuously contact the main gear 10, allowing them to rotate continuously. This rotation of the driven gears 12 drives the connecting rod 11 and the driven gear 13 at the bottom to rotate together. Since the driven gear 13 also meshes with the driven gear 15, its continuous rotation drives the driven gear... The three gears 15 rotate together, thereby driving the rotating rod 14 to rotate continuously through the driven gear 15. At this time, the rotation of the rotating rod 14 will drive the bottom connecting plate 16 to rotate around the rotating rod 14 as the center, thereby driving multiple stirring blades 18 to rotate and stir inside the mixing tank 1. Through the cooperation between multiple stirring blades 18 and multiple stirring blades 9, the stirring range and stirring stroke of the mixing device are effectively expanded, greatly improving the stirring efficiency of the mixing device. This allows for better dispersion and mixing of raw materials, effectively improving mixing efficiency, and making the uniformity of the anti-electromagnetic interference film material and the performance of the final product more perfect.
[0038] Reference Figure 2 and Figure 3 A scraper 19 is fixedly connected to the bottom end of the stirring rod 8, and scrapers 20 are fixedly connected to both sides of the scraper 19.
[0039] During the stirring process, the stirring rod 8 drives multiple stirring blades 9 to stir, which also drives the scraper 19 to rotate along the bottom surface of the mixing tank 1. Through the cooperation of the scraper 19 and the scraper 20, the raw materials at the bottom of the mixing tank 1 can be stirred and scraped off to prevent the raw materials from settling and sticking to the bottom of the mixing tank 1.
[0040] Reference Figure 1 and Figure 4The discharge assembly includes a fixed block 24 fixedly connected to the bottom of the discharge port 6. A baffle 25 is fixedly connected inside the fixed block 24. A motor 26 is fixedly connected to one side of the baffle 25. An auger 27 is rotatably connected to the other side of the baffle 25. The output end of the motor 26 is fixedly connected to one end of the auger 27.
[0041] When in use, the motor 26 can be started to drive the auger 27 to rotate continuously. The rotation of the auger 27 can quickly transport the mixed raw materials out, so that the raw materials can always be mixed during transportation.
[0042] Reference Figure 3 and Figure 4 The surfaces of the main gear 10 and driven gear 12 are provided with a waterproof layer, as are the surfaces of driven gear 2 13 and driven gear 3 15. The waterproof layer is a galvanized layer.
[0043] In use, the galvanized waterproof layer applied to the surfaces of the main gear 10, driven gear 12, driven gear 2 13, and driven gear 3 15 can effectively provide them with a certain degree of waterproof and rust prevention.
[0044] The implementation principle of the raw material mixing device for the production of anti-electromagnetic interference film in this embodiment is as follows: In use, the raw materials for the production of anti-electromagnetic interference film are first poured into the mixing tank 1 through the feed inlet 3. Then, the motor 7 is started to drive the three-sided block 5 to rotate continuously. Guided by the rotation of the three-sided block 5, the bottom stirring rod 8 drives multiple stirring blades 9 to rotate continuously inside the mixing tank 1, thereby performing simple stirring of the raw materials inside the mixing tank 1. While the multiple stirring blades 9 are stirring the raw materials, the continuous rotation of the three-sided block 5 drives multiple driven gears 12 to move along with the three-sided block 5. Because the main gear 10 and the multiple driven gears 12 are meshed together, during the movement of the three-sided block 5, the driven gears 12 will continuously contact the main gear 10, allowing the multiple driven gears 12 to rotate continuously. At this time, the rotation of the driven gears 12 will drive the connecting rod 11 and the driven gear 13 at the bottom to rotate together. Because the driven gear 13 and the driven gear 15 are connected... Since they mesh with each other, as the driven gear 13 rotates continuously, it will drive the driven gear 15 to rotate as well. In turn, the driven gear 15 will drive the rotating rod 14 to rotate continuously. At this time, the rotation of the rotating rod 14 will drive the bottom connecting plate 16 to rotate around the rotating rod 14 as the center. This will drive the multiple stirring blades 18 to rotate and stir inside the mixing tank 1. Through the cooperation between the multiple stirring blades 18 and the multiple stirring blades 9, the stirring range and stirring stroke of the mixing device are effectively expanded, and the stirring efficiency of the mixing device is greatly improved. This allows for better dispersion and mixing of the raw materials, effectively improving the mixing efficiency and making the uniformity of the anti-electromagnetic interference film material and the performance of the final product more perfect. Secondly, during the stirring process of the stirring rod 8 driving the multiple stirring blades 9, the scraper 19 will also rotate along the bottom surface of the mixing tank 1. Through the cooperation between the scraper 19 and the scraper 20, the raw materials at the bottom of the mixing tank 1 can be stirred and scraped off to prevent the raw materials from depositing and adhering to the bottom of the mixing tank 1.
[0045] In addition, during the mixing process, multiple heating wires 22 can be activated to continuously heat the inside of the mixing tank 1, so that the raw materials inside can always be kept at a suitable temperature, so as to prevent the raw materials from sticking together and solidifying due to low temperature, which would affect the mixing efficiency. After the mixing is completed, the valve 23 can be opened to allow the mixed raw materials to enter the discharge component through the discharge port 6. Then, the motor 26 is started to drive the auger 27 to rotate continuously. The rotation of the auger 27 can quickly transport the mixed raw materials out, so that the raw materials can always be kept mixed during transportation.
