Description

Technical Field

[0001] This utility model belongs to the field of drying equipment technology, and specifically relates to a drying equipment for drying film products. Background Technology

[0002] Conventional dryers have several limitations when used for drying thin-film products. Firstly, they pose a high risk of thermal degradation. Most thin-film products typically contain heat-sensitive organic solvents and lithium salts. Conventional dryers use a uniform high-temperature heating method, resulting in low temperature control precision and poor uniformity. This easily leads to localized overheating, causing solvent decomposition and lithium salt degradation, producing acidic byproducts and gases. This significantly reduces the chemical purity and electrochemical stability of the thin-film product, ultimately affecting the battery's cycle life and safety.

[0003] Secondly, solvent residue is difficult to completely remove. The core objective of drying is to remove trace amounts of moisture and solvent. Ordinary dryers mainly rely on simple heating and evaporation, which has very low removal efficiency for solvents with high boiling points. Under normal pressure and static air conditions, solvent vapor easily reaches saturation in the chamber and re-condenses, resulting in insufficient solvent residue to meet actual requirements.

[0004] Therefore, how to provide a drying equipment that enables uniform drying of film products in a high-temperature environment is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The main objective of this invention is to provide a drying device for film products, thereby solving the aforementioned technical problems. The device includes an airflow circulation assembly, heating rods, and a roller mechanism. The coordinated operation of these components creates a highly integrated drying environment, enabling precise and coordinated control of temperature and airflow distribution, improving drying efficiency, and preventing localized overheating or insufficient drying.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A drying device for drying film products includes a support frame with a working chamber at the top. Multiple drying chamber doors are connected to both the front and rear sides of the working chamber. Connection holes are provided at both ends of the working chamber. Roller mechanisms are provided on the outer wall of the support frame near the connection holes and on the inner wall of the support frame. Multiple heating rods are provided on the inner wall of the support frame, located below the roller mechanisms. A drying ventilation pipe is also arranged around the inner wall of the support frame between the heating rods and the roller mechanisms. The drying ventilation pipe is connected to an airflow circulation assembly and has multiple air outlets.

[0007] Furthermore, the airflow circulation assembly includes a blower, an electrical box, and a high-temperature ventilation duct. The electrical box and the blower are both fixed on a bracket. The air inlet of the blower is connected to an air inlet duct. The end of the air inlet duct away from the blower extends to below the heating rod inside the working chamber. The air outlet of the blower is connected to one end of the high-temperature ventilation duct. The other end of the high-temperature ventilation duct is connected to a drying ventilation duct. The blower is electrically connected to the electrical box, and the electrical box is also electrically connected to the heating rod.

[0008] Furthermore, the idler mechanism includes an idler mounting component, a first substrate idler, and two second substrate idlers. Idler mounting components are correspondingly provided on the outer wall of the bracket near the connection hole and on the inner wall of the bracket. The second substrate idlers are rotatably connected to the idler mounting component on the outer wall of the bracket near the connection hole, and the first substrate idlers are rotatably connected to the idler mounting component on the inner wall of the bracket.

[0009] Furthermore, the drying oven door is also equipped with insulation cotton.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This invention is equipped with an airflow circulation component, a heating rod, and a roller mechanism. The coordinated operation of the airflow circulation component, the heating rod, and the roller mechanism creates a highly integrated high-temperature drying environment. Solvents in film products are less likely to recondense in this high-temperature drying environment, and precise coordinated control of temperature and airflow distribution is achieved, improving drying efficiency while avoiding local overheating or insufficient drying. The airflow circulation component ensures uniform heat distribution inside the chamber, effectively preventing uneven film formation or defects. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1-3 As shown, this utility model provides a drying device for drying film products, including a support 10. The top of the support 10 is provided with a working chamber. Multiple drying chamber doors 5 are connected to the front and rear sides of the working chamber. Connection holes are provided at both ends of the working chamber. Roller mechanisms are provided on the outer wall of the support 10 near the connection holes and on the inner wall of the support 10. Multiple heating rods 4 are provided on the inner wall of the support 10. The heating rods 4 are located below the roller mechanisms. A drying ventilation pipe 1 is also arranged around the inner wall of the support 10 between the heating rods 4 and the roller mechanisms. The drying ventilation pipe 1 is connected to an airflow circulation component. Multiple air outlets 2 are provided on the drying ventilation pipe 1. The air containing heat near the heating rods 4 can be transferred to the air outlets 2 for discharge, ensuring heat balance, improving drying effect, and making the substrate drying more uniform.

[0018] In this embodiment, the airflow circulation assembly includes a blower 8, an electrical box 9, and a high-temperature ventilation duct 7. Both the electrical box 9 and the blower 8 are fixed to a bracket 10. The air inlet of the blower 8 is connected to an air inlet duct, with one end of the air inlet duct extending away from the blower 8 to below the heating rod 4 inside the working chamber. The air outlet of the blower 8 is connected to one end of the high-temperature ventilation duct 7, and the other end of the high-temperature ventilation duct 7 is connected to the drying ventilation duct 1. The blower 8 is electrically connected to the electrical box 9, which is also electrically connected to the heating rod 4. The high-temperature ventilation duct 7, in conjunction with the heating rod 4, circulates the heated air, creating a highly integrated drying environment and achieving precise and coordinated control of temperature and airflow distribution. The heating rod 4 maintains a uniform and stable high-temperature field, avoiding localized overheating or insufficient drying. The airflow circulation design formed by the high-temperature ventilation duct 7 and the drying ventilation duct 1 ensures uniform heat distribution inside the chamber, effectively preventing uneven film formation or defects.

[0019] In this embodiment, the idler roller mechanism includes an idler roller mounting component 11, a first substrate idler roller 3, and two second substrate idler rollers 6. Idler roller mounting components 11 are correspondingly provided on the outer wall of the bracket 10 near the connecting hole and on the inner wall of the bracket 10. The second substrate idler rollers 6 are rotatably connected to the idler roller mounting component 11 on the outer wall of the bracket 10 near the connecting hole, and the first substrate idler roller 3 is rotatably connected to the idler roller mounting component 11 on the inner wall of the bracket 10. The first substrate idler roller 3 and the second substrate idler roller 6 can pull the substrate to be dried evenly from inside the bracket 10 through the drying process by rotation, and the substrate to be dried can be dragged and pulled manually or by a motor during use.

[0020] In this embodiment, the drying oven door 5 is also equipped with heat-insulating cotton, which ensures the heat insulation performance of the entire drying oven door 5, greatly reducing the heat loss from the oven to the outside. This not only significantly improves the efficiency of heat energy utilization but also effectively ensures the continuous stability of the temperature field inside the drying oven door 5. Under this uniform and stable thermal environment, the material is heated evenly, and the solvent evaporation rate is consistent, thereby ensuring the consistency of the drying effect and providing a key guarantee for the thickness uniformity, structural integrity, and performance reliability of the final product. In addition, the drying oven door 5 is also connected to an oven locking handle.

[0021] Working principle: The substrate to be dried is laid on top of the first substrate roller 3 and the second substrate roller 6. The substrate to be dried is pulled forward at a constant speed by manual labor or motor. The heating rod 4 and the blower 8 are started by the electrical box 9. The blower 8 draws the heated air from the heating rod 4 into the high-temperature ventilation pipe 7 through the air inlet pipe and discharges it through the air outlet 2 on the drying ventilation pipe 1, thereby forming a stable and uniform hot air field inside the drying equipment to quickly dry the substrate.
