[0002] PET film is a packaging film with comprehensive performance. It has good transparency and gloss; good airtightness and aroma retention; moderate moisture resistance, with moisture permeability decreasing at low temperatures; and excellent mechanical properties, with its strength and toughness being the best among all thermoplastics.

[0003] Currently, PET film (polyethylene terephthalate film) coating is a common industrial processing technology. By coating the surface of a PET substrate with a functional coating, it is endowed with special properties (such as anti-reflection, conductivity, water resistance, high adhesion, etc.). The raw materials for PET film coating mainly include the substrate (PET film) and coating materials (such as resin, solvent, additives, etc.). The specific composition varies depending on the coating function and application field. The coating raw materials need to be mixed in proportion before use.

[0004] However, traditional mixing methods mostly involve manual stirring or simple mechanical stirring. These methods often result in uneven mixing, low efficiency, and difficulty in achieving precise proportion control. Furthermore, it is difficult to clean the mixing tank after mixing.

[0021] Please see Figure 1-6 As shown, a weighing device for mixing silicone in PET film coating processing includes: a mixing tank 1, a proportioning component 4 disposed on the top of the mixing tank 1, and a mixing component 5 disposed inside the mixing tank 1; The mixing assembly 5 includes a motor 51, a fixed gear ring 52, a mounting rod 53, a driven gear 54, a scraper 55, a stirring blade 56, a driven shaft 57, and a drive shaft 58. The motor 51 is located at the top of the mixing chamber 1, and the output end of the motor 51 is fixedly connected to the drive shaft 58. The fixed gear ring 52 is located inside the top wall of the mixing chamber 1. The mounting rod 53 is fixedly installed outside the drive shaft 58. The driven shaft 57 is limited and movablely inserted into the inside of the top mounting rod 53. The driven gear 54 is fixedly sleeved on the top outside of the driven shaft 57 and meshes with the fixed gear ring 52. The stirring blade 56 is fixedly installed outside the driven shaft 57. The two ends of the scraper 55 are fixedly connected to the upper and lower mounting rods 53 respectively, and the scraper 55 contacts the inner wall of the mixing chamber 1.

[0022] Specifically, the system includes a mixing component 5, a mixing box 1 for containing and mixing raw materials such as silicone and coatings, a proportioning component 4 for accurately weighing raw materials of different components to ensure accurate mixing ratios, and a motor 51 as the drive source that drives the entire mixing system by rotating the drive shaft 58. In use, the drive shaft 58 drives the mounting rod 53 to rotate, which in turn drives the driven shaft 57 to rotate as a whole. The driven gear 54 meshes with the fixed gear ring 52, causing the driven gear 54 to rotate in a circular motion around the axial center line of the drive shaft 58. The driven gear 54 can also rotate on its own axis, causing the driven shaft 57 to drive the stirring blades 56 to rotate, thereby stirring the materials. This ensures that the coating is not prone to dead zones during mixing and that the mixing is more thorough and uniform. At the same time, the mounting rod 53 drives the scraper 55 to rotate, which can scrape the inner wall of the mixing box 1 during cleaning to avoid material residue and facilitate continuous processing and use of the device.

[0023] In this embodiment, a support leg 11 is fixedly installed at the bottom of the mixing tank 1, a foot pad 12 is fixedly installed at the bottom end of the support leg 11, a liquid outlet pipe 13 is provided at the bottom of the mixing tank 1, and a heating ring 14 is embedded in the inner side wall of the mixing tank 1.

The heating ring 14 can be a metal ring with built-in heating wire.

[0025] The mixing tank 1 is equipped with a detection component 2 and a circulation mechanism 3 on both sides. The detection component 2 includes a flow tube 21, a detector 22 and a liquid pump 23. One end of the flow tube 21 is connected to the output end of the liquid pump 23, the input end of the liquid pump 23 is connected to the mixing tank 1, and the other end of the flow tube 21 is connected to the mixing tank 1. The detector 22 is threaded into the inside of the flow tube 21. The flow tube 21 is arranged in a U-shape.

[0026] Specifically, the detector 22 can be used with component analysis instruments, such as Fourier transform infrared spectrometers, gas chromatograph-mass spectrometers, etc. When in use, the liquid pump 23 is turned on, so that the liquid is transported through the flow tube 21. The detector 22 is used to detect the liquid and determine whether its detection ratio or mixing is qualified.

[0027] The circulation mechanism 3 includes a flow meter assembly 31, a return pipe 32, a pump 33, and a circulation pipe 34. The flow meter assembly 31 is disposed on the outer wall of the mixing tank 1. The output end of the flow meter is connected to the mixing tank 1 through the circulation pipe 34. The input end of the flow meter is connected to the pump 33 through the return pipe 32. The input end of the pump 33 is connected to the mixing tank 1.

[0028] Specifically, when the detector 22 does not mix sufficiently, the liquid pump 33 can be turned on, so that the liquid is drawn through the return pipe 32 and the circulation pipe 34, and then the liquid at the bottom is transported to the top, so that the liquid flows back into the mixing tank 1 for further stirring and mixing, making the mixing more thorough, avoiding the presence of residue at the bottom that cannot be mixed, and improving the mixing effect and efficiency.

[0029] The proportioning assembly 4 includes a support column 41, a top plate 42, a proportioning cylinder 43, a liquid inlet pipe 44, a delivery pipe 45, an air inlet pipe 46, an air pump 47, and a weighing scale 48. The support column 41 is fixedly installed on the top of the mixing tank 1, and its top end is fixedly connected to the top plate 42. The proportioning cylinder 43 is located on the top of the top plate 42. Multiple proportioning cylinders are provided, and the side wall is provided with a graduated glass plate for easy observation of its liquid volume. The air pump 47 is located on the top of the proportioning cylinder 43, and the output end of the air pump 47 is connected to the proportioning cylinder 43. The input end of the air pump 47 is connected to the air inlet pipe 46. The weighing scale 48 is located at the bottom of the proportioning cylinder 43. The proportioning cylinder 43 and the mixing tank 1 are connected through the delivery pipe 45.

[0030] Specifically, the support column 41 and the top plate 42 are fixed on the mixing tank 1 to fix and support the proportioning cylinder 43, ensuring its stability.

The weighing meter 48 is installed at the bottom of the proportioning cylinder 43, which can monitor and record the weight of each added liquid in real time to ensure the accuracy of the proportioning. When different liquids reach the appropriate weight, the air pump 47 can be turned on to pressurize the proportioning cylinder 43, thereby enabling the liquids to be quickly transported to the mixing tank 1 for mixing, improving its transport efficiency.

[0031] In summary, compared with the prior art, this weighing device for mixing has at least the following beneficial effects: By incorporating a mixing component 5, a mixing tank 1 is used to contain and mix raw materials such as silicone and coatings; a proportioning component 4 is used to accurately weigh raw materials of different components, ensuring accurate mixing ratios; a motor 51 serves as the drive source, rotating the drive shaft 58 to drive the entire mixing system. During use, the drive shaft 58 drives the mounting rod 53 to rotate, which in turn drives the driven shaft 57 to rotate as a whole. This is achieved through the meshing of the driven gear 54 and the fixed gear ring 52, causing the driven gear 54 to rotate in a circular motion around the axial center line of the drive shaft 58. Simultaneously, the driven gear 54 can also rotate on its own axis, causing the driven shaft 57 to drive the stirring blades 56 to rotate, thus performing a stirring operation on the materials. This prevents dead zones from forming during coating mixing, resulting in more thorough and uniform mixing. Furthermore, the mounting rod 53 drives the scraper 55 to rotate, allowing for scraping of the inner wall of the mixing tank 1 during cleaning, preventing material residue and facilitating continuous processing and use of the device.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
