Description

Technical Field

[0001] This application relates to the field of thin film production, and in particular to a mixing apparatus for thin film raw materials. Background Technology

[0002] The film raw material mixing device is a special equipment used for the pretreatment of raw materials in the production of plastic film. It mainly realizes the functions of mixing, coloring and drying of raw materials to ensure the uniformity of film materials and processing efficiency.

[0003] Utility model patent CN213797524U discloses a raw material mixing device for PVC film processing, including a mounting plate. A mixing tank is arranged in the middle of the upper surface of the mounting plate, and a mixing heating column is arranged at the bottom of the mixing tank. A heating tube is arranged inside the mixing heating column. A feeding funnel is arranged on one side of the upper surface of the mixing tank. A screening column is arranged in the middle of one side of the inner side of the feeding funnel, and screening and stirring blades are arranged on the outer surface of the feeding funnel. A filter screen is arranged on one side of the inner side of the feeding funnel below the screening column. A discharge port is arranged at the lower part of one side of the outer surface of the mixing tank, and a sealing gasket is arranged at one end of the outer surface of the discharge port.

[0004] The above-mentioned raw material mixing device for PVC film processing uses a first motor to drive the screening column and screening stirring blades to rotate and stir the raw material particles. Small particles of raw material fall into the mixing tank through the filter screen 17 during the movement. Large particles of raw material are squeezed out from the screening outlet at one end of the feeding funnel by the screening stirring blades. However, the stirring blades drive the raw material to move, which easily causes the raw material to accumulate at one end of the feeding funnel, making it difficult to quickly squeeze out the large particles of raw material, resulting in a reduction in work efficiency.

[0008] By adopting the above technical solution, during use, raw materials are added to the screening tube through the feeding component. Then, the first motor drives the first auger to rotate, causing the first auger to transport the raw materials in the screening tube upwards and overflow from the top of the screening tube. The overflowing raw materials roll evenly on the annular screen plate, causing small particles of raw materials to fall into the mixing tank through the annular screen plate, while large particles of raw materials roll into the collection box. Then, the material in the collection box is discharged by the pushing component. This method avoids the problem of the stirring blades moving the raw materials, which can easily cause the raw materials to accumulate at one end of the feeding funnel, making it difficult to quickly squeeze out large particles of raw materials and reducing work efficiency.

[0013] Preferably, a mixing rod is rotatably connected to the lower surface of the fixed disk, the mixing rod is fixedly connected to the first auger, and a plurality of mixing plates for mixing raw materials are fixedly connected to the side wall of the mixing rod.

[0014] By adopting the above technical solution, while the first motor drives the first auger to rotate, it can also drive the mixing rod to rotate, so that the mixing plate can stir and mix the raw materials that fall into the mixing tank.

[0015] Preferably, the height of the screening tube is higher than the height of the annular baffle.

[0016] By adopting the above technical solution, the annular screen plate is tilted, causing the raw materials falling on the annular screen plate to roll and preventing the raw materials from accumulating on the annular screen plate.

[0017] Preferably, a discharge pipe is fixedly connected to the bottom of the mixing tank, and a solenoid valve is installed on the discharge pipe. The bottom of the mixing tank is funnel-shaped.

[0018] By adopting the above technical solution, the mixed raw materials in the mixing tank can be discharged through the discharge pipe by opening the solenoid valve. At the same time, the mixing tank with a funnel-shaped bottom can prevent some raw materials from remaining in the mixing tank.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. This application utilizes the coordinated arrangement of structures such as a screening tube, annular baffle, and annular screen plate. During use, raw materials are added to the screening tube via a feeding assembly. Then, a first motor drives a first auger to rotate, causing the auger to convey the raw materials in the screening tube upwards and overflow from the top of the screening tube. The overflowing raw materials roll evenly on the annular screen plate, causing small particles to fall into the mixing tank through the annular screen plate, while large particles roll into the collection box. The raw materials in the collection box are then discharged by a pushing assembly. This method minimizes the problem of the stirring blades moving the raw materials, which can easily cause the raw materials to accumulate at one end of the feeding funnel, making it difficult to quickly squeeze out large particles and reducing work efficiency.

[0021] 2. When the first motor drives the first auger to rotate, the swing rod can drive the pusher plate to move inside the collection box, so that the pusher plate pushes the raw materials accumulated in the collection box, moves the raw materials to the opening, and then discharges them through the guide pipe, preventing the raw materials from accumulating in the collection box.

The screening component includes a fixed plate 2, a connecting rod 3, a screening tube 4, a first auger 5, an annular baffle 6, an annular screen plate 7, a collection box 8, and a first motor 9.

[0030] The fixed plate 2 is located at the top of the inside of the mixing tank 1. Multiple connecting rods 3 are provided, with one end fixedly connected to the side wall of the fixed plate 2 and forming a ring array. The other end of each connecting rod 3 is fixedly connected to the mixing tank 1. The screening pipe 4 is fixedly connected to the upper surface of the fixed plate 2. The first auger 5 is installed inside the screening pipe 4 to convey the raw material inside the screening pipe 4 upward. The annular baffle 6 is fixedly connected to the top of the mixing tank 1. The annular screen plate 7 is sleeved on the top of the screening pipe 4 and fixedly connected. The side wall of the annular screen plate 7 away from the screening pipe 4 is fixedly connected to the top of the side wall of the annular baffle 6. The collection box 8 is sleeved on the top of the annular baffle 6 and fixedly connected to the side wall of the annular baffle 6. The first motor 9 is installed on the upper surface of the collection box 8 and its output end is fixedly connected to the first auger 5. The collection box 8 is provided with a pushing component for discharging the raw material inside the collection box 8. The screening pipe 4 is provided with a feeding component for adding raw materials.

[0031] Reference Figure 2 and Figure 4 The pushing assembly includes an opening 21 on one side of the bottom of the collection box 8. A pushing plate 10 is provided inside the collection box 8. A swing rod 11 is fixedly connected to the top of the pushing plate 10. The end of the swing rod 11 away from the pushing plate 10 is fixedly connected to the top side wall of the first auger 5. A guide pipe 12 is fixedly connected to the bottom of the collection box 8 at the opening 21. When the first motor 9 drives the first auger 5 to rotate, the swing rod 11 can drive the pushing plate 10 to move inside the collection box 8, so that the pushing plate 10 pushes the raw material accumulated in the collection box 8, so that the raw material 8 moves to the opening 21 and is discharged through the guide pipe 12, preventing the raw material from accumulating in the collection box 8.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The feeding assembly includes a conveying pipe 13 fixedly connected to the bottom of one side wall of the screening pipe 4. The conveying pipe 13 is connected to the screening pipe 4. A second auger 14 is rotatably connected inside the conveying pipe 13. A second motor 15 for driving the second auger 14 to rotate is installed at the end of the conveying pipe 13 away from the screening pipe 4. A feed hopper 16 is fixedly connected to the upper side of the end of the conveying pipe 13 near the second motor 15. Raw materials are added into the feed hopper 16. By starting the second motor 15 to drive the second auger 14 to rotate, the raw materials can be conveyed through the conveying pipe 13 into the screening pipe 4 for screening.

[0033] Reference Figure 2 A mixing rod 17 is rotatably connected to the lower surface of the fixed plate 2. The mixing rod 17 is fixedly connected to the first auger 5. Multiple mixing plates 18 for mixing raw materials are fixedly connected to the side wall of the mixing rod 17. When the first motor 9 drives the first auger 5 to rotate, it can drive the mixing rod 17 to rotate, so that the mixing plates 18 can stir and mix the raw materials that fall into the mixing tank 1.

[0034] Reference Figure 2 The height of the screening tube 4 is higher than the height of the annular baffle 6, so that the annular screen plate 7 is in an inclined state, causing the raw material falling on the annular screen plate 7 to roll and prevent the raw material from accumulating on the annular screen plate 7.

[0035] Reference Figure 2 A discharge pipe 19 is fixedly connected to the bottom of the mixing tank 1. A solenoid valve 20 is installed on the discharge pipe 19. The bottom of the mixing tank 1 is funnel-shaped. By opening the solenoid valve 20, the mixed raw materials in the mixing tank 1 can be discharged through the discharge pipe 19. At the same time, the funnel-shaped bottom of the mixing tank 1 can prevent some raw materials from remaining in the mixing tank 1.

[0036] The implementation principle of a film raw material mixing device according to an embodiment of this application is as follows: During use, raw material is added to the feed hopper 16, and then the second motor 15 is started to drive the second auger 14 to rotate, causing the raw material to be conveyed through the conveying pipe 13 to the screening pipe 4. Then, the first motor 9 is started to drive the first auger 5 to rotate, causing the first auger 5 to convey the raw material in the screening pipe 4 upwards, overflowing from the top of the screening pipe 4. The overflowing raw material rolls evenly on the annular screen plate 7, causing small particles of raw material to fall into the mixing tank 1 through the annular screen plate 7, and large particles of raw material to roll into the collection box 8. Simultaneously, the swing rod 11 can be used to... When the auger 5 rotates, it drives the pusher plate 10 to move within the collection box 8, pushing the raw materials accumulated in the collection box 8 to the opening 21, and then discharging them through the guide pipe 12. This prevents the raw materials from accumulating in the collection box 8. At the same time, as the first motor 9 drives the first auger 5 to rotate, it also drives the mixing rod 17 to rotate, causing the mixing plate 18 to stir and mix the raw materials that fall into the mixing tank 1. This minimizes the problem of the mixing blades moving the raw materials, which can easily cause the raw materials to accumulate at one end of the feeding funnel, making it difficult to quickly squeeze out large particles of raw materials and reducing work efficiency.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
