Description

Technical Field

[0001] The present invention relates to the technical field of fireproof cloth coating production, and specifically to a drying device for fireproof cloth coating. Background Art

[0002] In daily life and work, as a special material with flame retardant properties, fireproof cloth is widely used in various occasions that require fire prevention and disaster reduction. This kind of cloth not only helps to reduce the losses caused by fires, but also can quickly extinguish the initial fire in case of emergency. Therefore, fireproof cloth has become an indispensable protective equipment in many special industries and jobs. The so-called fireproof cloth refers to those cloths that can effectively inhibit combustion or have high flame retardancy.

[0003] Fireproof cloth is mainly composed of materials such as silica gel, rubber, glass fiber, and basalt. Among them, silicone rubber coated fiberglass cloth is one of the most common types of fireproof cloth. Fiberglass has the characteristics of high temperature resistance and corrosion resistance, while silicone rubber is famous for its excellent heat resistance.

[0004] Coating drying is a key step in the production process of fireproof cloth. By heating, the solvent or moisture in the coating material is volatilized, so as to achieve curing and performance stability. In the prior art, usually the method of passing heat-conducting oil into the heating roller is adopted. The coated fireproof cloth is closely attached to the heating roller, and the coated cloth is heated by multiple heating rollers, so that the moisture in the coating is heated and evaporated to complete the coating drying treatment. However, although the above drying treatment method can achieve the purpose of drying, there are problems of serious heat source energy loss and low production efficiency. In addition, the high temperature of the heating roller directly contacts the surface of the coating, which will scratch the surface of the coating or cause the coating to peel off. Summary of the Invention

[0005] In order to overcome some of the problems mentioned in the above background, the present invention provides a drying device for fireproof cloth coating.

[0006] The technical solution adopted by the present invention is as follows: A drying device for fireproof cloth coating includes a calendering mechanism, multiple groups of wind-heat mechanisms, and a heat baking mechanism.

DETAILED DESCRIPTION OF THE INVENTION

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0020] As Figures 1-7 shown, in some embodiments, a drying device for a fireproof cloth coating includes a calendering mechanism 2, multiple groups of wind-heat mechanisms 3, and a heat baking mechanism 4. Among them, the calendering mechanism 2 is arranged on the front side of the wind-heat mechanism 3, and the heat baking mechanism 4 is arranged between multiple groups of wind-heat mechanisms 3. This layout design aims to optimize the drying process and ensure that the coating of the fireproof cloth 6 can obtain uniform and efficient heat treatment during the drying process. The function of the calendering mechanism 2 is to calender the fireproof cloth 6 flatly to prepare for the subsequent wind-heat treatment and baking processes.

[0021] Specifically, the heat baking mechanism 4 includes a bearing cylinder 41 and a heating module 42. Among them, the heating module 42 is arranged inside the bearing cylinder 41. Infrared heating rays are generated by the heating module 42, and the direction of the rays diffuses outward along the heating module 42, so that it acts uniformly on the bearing cylinder 41. While the bearing cylinder 41 is in a heated state, it passes through the cylinder wall 413 of the bearing cylinder 41 and acts on the fireproof cloth 6, baking the moisture on the surface and inside of the fireproof cloth 6 and evaporating it into the air to achieve the drying treatment of the fireproof cloth 6.

[0022] In this embodiment, the bearing cylinder 41 can rotate relative to the heating module 42. When the fireproof cloth 6 contacts the outer wall of the bearing cylinder 41, the bearing cylinder 41 will rotate as the fireproof cloth 6 moves, which helps to prevent the incompletely cured coating on the surface of the fireproof cloth 6 from being squeezed or displaced, thereby ensuring the uniformity of the coating during the drying process.

[0023] To further improve the thermal efficiency, multiple through holes 412 are designed on the barrel wall 413 of the bearing barrel 41. These through holes 412 help the heat to spread evenly over the entire surface of the bearing barrel 41, making the baking process more uniform and efficient. The setting of the through holes 412 not only enhances the heat transfer efficiency but also effectively prevents local overheating, protecting the coating of the fireproof cloth 6 from damage. In addition, these through holes 412 are in contact with the fireproof cloth 6, capable of discharging the moisture evaporated from the coating and discharging it from the bearing barrel 41 through the through holes 412 that are not in contact with the fireproof cloth 6.

[0024] In addition, the present invention further includes a flow guiding mechanism 5, which is arranged at the rear side of the thermal baking mechanism 4. The main function of the flow guiding mechanism 5 is to guide the circulation direction of the hot air, ensuring that the hot air can flow along a predetermined path, thereby improving the utilization rate of the hot air and optimizing the baking effect. By precisely controlling the flow of the hot air, the uniformity and efficiency of the baking process can be further improved, ensuring the quality of the final product.

[0025] It should be noted that in this embodiment, when the fireproof cloth 6 is subjected to the drying treatment, it first passes through the calendering mechanism 2, which preliminarily flattens the coating to ensure the uniformity of the coating, thereby improving the drying effect.

[0026] Next, two hot air mechanisms 3 are arranged between the calendering mechanism 2 and the first thermal baking mechanism 4. The fireproof cloth 6 passes through these two hot air mechanisms 3, and the hot air mechanisms 3 conduct preliminary drying on the coating to prevent the fireproof cloth 6 from sticking when it comes into contact with the bearing barrel 41.

[0027] Subsequently, the heating module 42 emits infrared heating rays outward, which act on the bearing barrel 41 and pass through the bearing barrel 41 to act on the fireproof cloth 6, causing the moisture inside it to evaporate, achieving the drying treatment of the fireproof cloth 6.

[0028] Finally, a hot air mechanism 3 and multiple flow guiding mechanisms 5 are arranged at the rear side of the thermal baking mechanism 4. After the fireproof cloth 6 passes through the thermal baking mechanism 4, the hot air mechanism 3 blows hot air to it for the final drying treatment, and the flow guiding mechanisms 5 guide the hot air circulation to ensure that the hot air continuously acts on the fireproof cloth 6, further improving the uniformity and production efficiency of the drying process and ensuring the drying quality.

[0029] Through the mutual cooperation of the hot air mechanism 3 and the heating module 42, the stability and uniformity of the drying process of the fireproof cloth 6 are achieved, and through the flow guiding mechanism 5, the utilization efficiency of the hot air is improved, and the drying efficiency of the fireproof cloth 6 is increased.

[0030] Such as Figures 5-8As shown, in some embodiments, the hot baking mechanism 4 further includes a fixed shaft 43 and an end fixing module 44. The fixed shaft 43 is arranged inside the heating module 42, and its main function is to provide a stable fixed axis for the hot baking mechanism 4, ensuring that the entire hot baking mechanism 4 can operate stably during the baking process. The end fixing module 44 is arranged at both ends of the fixed shaft 43, and its main function is to further ensure the stability of the entire hot baking mechanism 4. The heating module 42 is arranged between the two end fixing modules 44, and its main responsibility is to provide the necessary heat to dry the coating of the fireproof cloth 6. Both ends of the bearing cylinder 41 are slidably connected to the two end fixing modules 44 respectively. Such a design can ensure that the bearing cylinder 41 can rotate smoothly during the baking process, thereby uniformly heating the fireproof cloth 6 and ensuring the stability of the coating.

[0031] Specifically, the end fixing module 44 includes a fixing plate 441 and an end plate 442. The fixing plate 441 is arranged on the outer side of the end plate 442, playing the role of fixing the fixed shaft 43 and ensuring that the axis of the hot baking mechanism 4 does not shift during operation. The end plate 442 is provided with a groove, and the groove is connected to the bearing cylinder 41. Such a design can make the bearing cylinder 41 more stable during rotation.

[0032] In addition, a cooling channel 431 is arranged inside the fixed shaft 43. Through the circulating flow of the coolant in the cooling channel 431, the internal temperature of the hot baking mechanism 4 can be effectively reduced. Through the coolant circulation in the cooling channel 431, the temperature of the hot baking mechanism 4 can be effectively controlled, ensuring the stability and reliability of the hot baking mechanism 4.

[0033] Furthermore, in some embodiments, to ensure the stability of the rotation of the bearing cylinder 41, sliding blocks 411 are provided at both ends of the cylinder wall 413 and are realized through sliding connection with the groove. This structural design allows the sliding blocks 411 to move freely in the groove of the cylinder wall 413. In addition, the setting of the sliding blocks 411 can also reduce the friction between the bearing cylinder 41 and the end plate 442, enabling the bearing cylinder 41 to rotate stably, thereby further protecting the surface quality of the fireproof cloth 6 and avoiding unnecessary damage to the coating.

[0034] Even further, in some embodiments, multiple hot baking mechanisms 4 are provided, such that the fireproof cloth 6 can be baked sequentially through these multiple hot baking mechanisms 4; this design ensures that the fireproof cloth 6 can be fully and evenly baked during the production process, thereby improving the quality and performance of the product.

[0035] Specifically, the heating module 42 includes a plurality of heating tubes 422 and a reflector 421, and the reflector 421 is arranged between the heating tubes 422 and the fixed shaft 43.

[0036] Specifically, a plurality of heating tubes 422 are sequentially arranged along the outer side of the fixed shaft 43 to form a continuous heating area, thereby ensuring that the fireproof cloth 6 can be uniformly and continuously heated when passing through; this continuous heating method effectively avoids quality problems of the fireproof cloth 6 caused by uneven temperature, such as local overheating or insufficient baking.

[0037] In addition, the reflector 421 is designed in a wavy structure. Such a design enables the heating tubes 422 to be arranged at the lower positions of the reflector 421, so that the heat can be effectively reflected to the fireproof cloth 6 through the wavy shape of the reflector 421, further improving the heating efficiency and uniformity; the wavy reflector 421 not only increases the heat reflection area, but also, through its unique structural design, helps the heat to be evenly distributed on the surface of the fireproof cloth 6, thereby enhancing the overall baking effect.

[0038] As Figure 4 shown, in some embodiments, the air-heating mechanism 3 includes a connecting pipe 32 and a plurality of air outlets 31, and these air outlets 31 are arranged in sequence along the transverse direction of the fireproof cloth 6. Specifically, the drying device transports the hot air generated by the heat source to each air outlet 31 through the connecting pipe 32, thereby ensuring that the hot air can evenly cover the entire surface of the fireproof cloth 6. This design not only improves the drying efficiency but also ensures the uniformity of the coating.

[0039] As Figures 1-6 shown, in some embodiments, the device further includes a drying box 1. The drying box 1 includes a box body 11, and a first support plate 12 and a second support plate 13 are respectively installed on both sides thereof. The first support plate 12 is connected to the heat baking mechanism 4 to provide stable support for the heat baking mechanism 4. The second support plate 13 is connected to the calendering mechanism 2 to provide support for the calendering mechanism 2. The diversion mechanism 5 is arranged on the rear side wall of the box body 11, and the air-heating mechanism 3 is connected to the two side plates of the box body 11. Through the above connection method, the entire device is in a stable structure.

[0040] In the structural design of the box body 11, there are two parts, an inlet and an outlet. At the inlet, a calendering mechanism 2 is arranged, and its main function is to perform preliminary flattening on the fireproof cloth 6 after it enters the drying box 1, which can ensure the uniformity of the coating and thus improve the drying effect. At the outlet, a diversion mechanism 5 is arranged, and its function is to guide the circulation direction of the hot air in the box body 11 so that it always acts on the surface of the fireproof cloth 6 to improve the drying efficiency.

[0041] Furthermore, in some embodiments, a plurality of diversion mechanisms 5 are configured in the device. These diversion mechanisms 5 are arranged vertically to ensure uniform guiding of the hot air circulation.

[0042] Among them, each flow guiding mechanism 5 includes a flow guiding plate 51 and a support frame 52. The support frame 52 is designed to be fixedly connected to the rear side wall of the box body 11 to provide stable support. The flow guiding plate 51 is connected to the support frame 52 and adjusts its angle to adapt to different drying requirements.

[0043] Furthermore, in some embodiments, the calendering mechanism 2 includes two calendering rollers 21. The fireproof cloth 6 passes between the two calendering rollers 21. The two calendering rollers 21 are respectively connected to two external driving motors. Through the collaborative work of these two external driving motors, the two calendering rollers 21 can rotate towards each other, thereby driving the fireproof cloth 6 to move forward. This design ensures the uniformity of the coating and significantly improves the quality of the final product.

[0044] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
