Description

Technical Field

[0001] This utility model relates to the field of thermal drying equipment, and in particular to a thermal drying equipment for aluminum foil production. Background Technology

[0002] The hot drying equipment is a key piece of equipment in the aluminum foil production process. It is mainly used to dry the residual moisture and related additives on the surface of aluminum foil after rolling, cleaning and other processes, so as to ensure the quality of subsequent aluminum foil winding and the stability of product performance.

[0003] Existing continuous production lines for multi-adaptive aluminum foil use internal heating devices to dry the liquid on the surface of the aluminum foil. This equipment needs to work in conjunction with the preceding cleaning equipment and the subsequent winding equipment to meet the drying requirements of aluminum foils of different thicknesses and widths. It is widely used in the workshop production process of aluminum foil manufacturers and is an important part of ensuring that aluminum foil products meet quality standards.

[0004] Existing thermal drying equipment for aluminum foil production has several drawbacks in practical applications. Firstly, existing equipment typically uses tensioning rollers to smooth the aluminum foil during drying and transportation. However, aluminum foil is relatively soft and brittle, and the force applied by the tensioning rollers can easily cause excessive stretching, leading to thinning and, in severe cases, breakage, thus affecting the production process. Secondly, existing equipment often uses hot air heating. During heating, components in the hot air combine with moisture on the aluminum foil surface to form water vapor. This water vapor accumulates inside the equipment over time, easily causing corrosion of components, shortening the equipment's lifespan, and increasing maintenance costs. Therefore, a new thermal drying equipment for aluminum foil production is proposed to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a hot drying device for aluminum foil production, which improves the problems in the prior art where the tensioning wheel flattens the aluminum foil, causing it to stretch and thin or break, and the hot air heating generates water vapor, which easily causes equipment corrosion.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a heat drying device for aluminum foil production, comprising a mounting frame, a heating chamber head section fixedly connected to the top outer wall of the mounting frame, a heating chamber tail section fixedly connected to the top outer wall of the mounting frame, a support frame fixedly connected to the outer wall of the mounting frame, a heating air pump fixedly connected to the top outer wall of the support frame, a heating pipe fixedly connected to the output end of the heating air pump, a suction air pump fixedly connected to the top outer wall of the support frame, a suction pipe fixedly connected to the input end of the suction air pump, a connecting block fixedly connected to the top outer wall of the mounting frame, a sliding groove formed on the inner wall of the connecting block, a slider slidably connected to the inner wall of the sliding groove, a spring fixedly connected to the top outer wall of the slider, and a roller rotatably connected to the inner wall of the slider.

[0007] As a further description of the above technical solution:

[0008] A motor is fixedly connected to the bottom outer wall of the mounting frame. The output end of the motor is connected to a transmission belt via a transmission wheel. The transmission belt is also connected to the top outer wall of the mounting frame via a transmission wheel.

[0009] As a further description of the above technical solution:

[0010] The ends of the air intake pipes are respectively fixedly connected to the top outer walls of the first section, the middle section, and the tail section of the heating chamber.

[0011] As a further description of the above technical solution:

[0012] The ends of the heating pipes are respectively fixedly connected to the top outer walls of the first section, the middle section, and the tail section of the heating chamber.

[0013] As a further description of the above technical solution:

[0014] The output end of the heating pipe should be set lower than the input end of the suction pipe.

[0015] As a further description of the above technical solution:

[0016] The end of the spring is fixedly connected to the inner wall of the connecting block.

[0017] As a further description of the above technical solution:

[0018] The slider is elastically connected to the connecting block by a spring. Several sets of connecting blocks are provided, and the several sets of connecting blocks are arranged horizontally in a straight line according to the center line of the transmission belt.

[0019] As a further description of the above technical solution:

[0020] The surface of the transmission belt is coated with an anti-slip and wear-resistant coating.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting rollers and springs, the elasticity of the springs can keep the rollers in constant contact with the surface of the aluminum foil. At the same time, multiple sets of rollers work together to smooth the foil, which can effectively prevent wrinkles from forming on the aluminum foil during transportation and drying. The device is equipped with multiple heating chambers, which, together with heating air pumps supplying heat through heating pipes and suction air pumps drawing air through suction pipes, can promptly discharge the water vapor generated by heating. In addition, the closed heating chamber structure significantly improves the efficiency of heating and drying aluminum foil, while also reducing the risk of water vapor causing corrosion to the equipment.

[0023] 2. In this utility model, by setting a transmission belt, the transmission belt and the roller are closely attached to each other to form a stable transportation structure, which can adapt to the transportation needs of aluminum foil of different thicknesses, ensure the stability of aluminum foil during transportation, and avoid damage to aluminum foil due to unstable transportation. In addition, the surface of the transmission belt is coated with an anti-slip and wear-resistant coating, which not only increases the friction between the transmission belt and the aluminum foil to prevent the aluminum foil from slipping during transportation, but also improves the wear resistance of the transmission belt, extends the service life of the transmission belt, and reduces equipment maintenance costs.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0032] Reference Figure 1 , Figures 3-4 This utility model provides an embodiment of a heat drying device for aluminum foil production, including a mounting frame 1. The mounting frame 1 serves as the supporting foundation for the entire device, providing a stable mounting carrier for each component. A heating chamber head section 2, a heating chamber middle section 3, and a heating chamber tail section 4 are fixedly connected to the top outer wall of the mounting frame 1, forming a closed drying space to achieve staged continuous drying of the aluminum foil. A support frame 9 is fixedly connected to the outer wall of the mounting frame 1, supporting and fixing a heating air pump 10 and a suction air pump 11 to ensure the stability of the two pumps during operation. A heating air pump 10 is fixedly connected to the top outer wall of the support frame 9, providing a heat source for drying. The heating air pump 10 is connected to an external heat source, which enters from its input end. A heating pipe 5 is fixedly connected to its output end, transporting the hot air generated by the heating air pump 10 to each heating chamber. The ends of the heating pipe 5 are respectively fixedly connected to the top of the heating chamber head section 2, the heating chamber middle section 3, and the heating chamber tail section 4. On the outer wall, a suction pump 11 is fixedly connected to the top outer wall of the support frame 9. The suction pump 11 is used to extract water vapor from the heating chamber. The suction pump 11 is connected to an external air collection device, and its input end is fixedly connected to a suction pipe 6. The suction pipe 6 is responsible for guiding the water vapor in each heating chamber to the suction pump 11. The ends of the suction pipe 6 are fixedly connected to the top outer walls of the first section 2, the middle section 3, and the tail section 4 of the heating chamber, respectively. The output end of the heating pipe 5 is set lower than the input end of the suction pipe 6. The reason is that after the hot air is output from the heating pipe 5, it will naturally diffuse upward. Setting its output end lower allows the hot air to more fully cover the surface of the aluminum foil and fully contact the water vapor on the surface of the aluminum foil to achieve efficient drying. The input end of the suction pipe 6 is higher, which can more quickly extract the water vapor formed by the combination of hot air and water vapor, avoid water vapor from lingering in the equipment, and prevent the hot air from being directly extracted without being fully utilized, thereby improving heat utilization efficiency and drying effect.

[0033] Reference Figures 3-5A connecting block 12 is fixedly connected to the top outer wall of the mounting bracket 1. The connecting block 12 provides installation and movement space for the slider 13 and the spring 15. A groove 14 is provided on its inner wall, which limits the sliding direction of the slider 13, ensuring that the slider 13 can only move in the vertical direction. The slider 13 is slidably connected to the inner wall of the groove 14. The slider 13 is used to install and fix the roller 8, and its position can be adjusted with the extension and retraction of the spring 15. The spring 15 is fixedly connected to the top outer wall of the slider 13. The spring 15 provides a downward elastic force to the slider 13 through its own elastic deformation. The roller 8 is always in contact with the aluminum foil surface. The end of the spring 15 is fixedly connected to the inner wall of the connecting block 12. The slider 13 is elastically connected to the connecting block 12 through the spring 15. The height of the roller 8 can be adaptively adjusted according to the thickness of the aluminum foil. Several sets of connecting blocks 12 are set in a straight line horizontally according to the center line of the transmission belt 16 to ensure that multiple sets of rollers 8 act evenly on the aluminum foil. The inner wall of the slider 13 is rotatably connected to the roller 8. The roller 8 rolls during the transportation of aluminum foil, which plays a smoothing role on the aluminum foil and avoids wrinkles.

[0034] Reference Figures 2-4 A motor 7 is fixedly connected to the bottom outer wall of the mounting frame 1. The motor 7 provides power to the transmission belt 16. Its output end is connected to the transmission belt 16 through a transmission wheel. The transmission wheel transmits the power of the motor 7 to the transmission belt 16, driving the transmission belt 16 to circulate. The transmission belt 16 is also connected to the top outer wall of the mounting frame 1 through a transmission wheel. The transmission belt 16 is used to carry and transport aluminum foil, realizing the continuous movement of aluminum foil between heating chambers. The surface of the transmission belt 16 is coated with an anti-slip and wear-resistant coating. The coating material is polyurethane elastomer, which has excellent wear resistance, tear resistance and elasticity. It can ensure sufficient friction with aluminum foil while avoiding the coating being too hard and scratching the surface of aluminum foil. It is also not easy to wear after long-term use, thus extending the service life of the transmission belt 16.

[0035] Working principle: First, the motor 7 fixed to the bottom outer wall of the mounting frame 1 is started. The power output of the motor 7 is transmitted to the transmission belt 16 through the transmission wheel, causing the transmission belt 16 to circulate along the transmission wheel at the top of the mounting frame 1. The aluminum foil to be dried is placed on the surface of the transmission belt 16. With the help of the anti-slip and wear-resistant coating of polyurethane elastomer material on the surface of the transmission belt 16, sufficient friction is ensured to prevent the aluminum foil from slipping while avoiding scratching the aluminum foil, thus achieving stable conveying of the aluminum foil towards the heating chamber. Before the aluminum foil enters the closed drying space formed by the connection of the first section 2, the middle section 3, and the tail section 4 of the heating chamber, the roller 8 in the connecting block 12 at the top of the mounting frame 1 is already in contact with the surface of the aluminum foil under the action of the spring 15. The spring 15 applies a downward elastic force to the slider 13 through its own elastic deformation. The slider 13 slides vertically along the slide groove 14, and the belt... The moving roller 8 adaptively adjusts its height to match the thickness of the aluminum foil, and multiple sets of rollers 8, horizontally arranged along the center line of the transmission belt 16, roll synchronously to smooth the aluminum foil during transportation and prevent wrinkles. At the same time, the heating air pump 10 and suction air pump 11 fixed on the support frame 9 are activated: the hot air generated by the heating air pump 10 is transported to each heating chamber through the heating pipe 5. Since the output end of the heating pipe 5 is lower than the input end of the suction pipe 6, the hot air naturally diffuses upward and can fully cover the surface of the aluminum foil, making full contact with the water vapor on the surface of the aluminum foil to achieve drying. The suction air pump 11 quickly extracts the water vapor formed by the combination of hot air and water vapor in the heating chamber through the suction pipe 6, avoiding water vapor retention that could cause equipment corrosion, and also preventing the hot air from being drawn away without being fully utilized. Finally, after being dried in stages, the aluminum foil completes the entire drying process with the transmission belt 16.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
