Description

Technical Field

[0001] The utility model relates to the technical field of coating spraying equipment, in particular to a surface spraying device for preparing nano thermal insulation materials. Background Art

[0002] Nano thermal insulation materials generally refer to thermal insulation materials whose thermal conductivity is lower than that of "air without convection" under predetermined conditions of use. They are essentially nano-pore mechanisms and have super thermal insulation and heat insulation capabilities that are 2-6 times higher than those of commonly used traditional materials. Above 300 degrees Celsius, the higher the temperature, the higher the thermal insulation effect of the latter is 2-3 times higher than that of aerogel composite thermal insulation materials. They are mainly made of silicon oxide nanopowder, special inorganic binders and a variety of thermal barrier inorganic components, and are evenly mixed with high-temperature fibers.

[0003] Existing surface spraying devices generally directly place the nano-insulating material into a spray box for spraying the coating, and then take out the material after the spraying is completed. However, when spraying the coating on this material, it is necessary to ensure the sealing of the environment to reduce contact with the air. Therefore, it is generally necessary to manually take out or fix the material. This results in manual intervention when spraying the coating on the material, which affects the working efficiency of the spraying device. Therefore, a device is needed to solve the problem.

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0021] like Figure 1-3 As shown, a surface spraying device for preparing nano thermal insulation materials is provided. In order to reduce manual intervention during the coating spraying of the material, the automatic loading and unloading of the nano thermal insulation material is realized, thereby effectively improving the working efficiency of the spraying device. A spray box 1 is provided here. The top of the spray box 1 is fixedly connected to a liquid storage tank 11, which is convenient for storing the spray liquid and facilitating long-term spraying operations. A slide rail 12 is provided on the top wall of the spray box 1. A spraying mechanism is slidably connected to the slide rail 12. The nano thermal insulation material can be sprayed at a uniform speed through the spraying mechanism. In order to facilitate the movement of the spraying mechanism, a slide mechanism can be installed on the slide rail 12. It should be noted that the slide mechanism is a prior art and will not be described in detail. A feeding control mechanism 3 is provided on the bottom side of the spray mechanism. The feeding control mechanism 3 includes a conveying roller 31 and an axle Rod 35, conveying roller 31 and shaft 35 are all provided with multiple and coaxially fixed connection, shaft 35 passes through conveying roller 31, and two ends of shaft 35 are rotatably connected with the inner wall of spray box 1, one side of shaft 35 is coaxially fixedly connected with multiple gears 32, toothed belt 36 is sleeved between adjacent gears 32, outer wall of shaft 35 at two ends is coaxially fixedly connected with pulley A34, the top of spray box 1 is rotatably connected with winding roller 39, one side of winding roller 39 is coaxially fixedly connected with pulley B38, transmission belt 37 is sleeved between pulley B38 and pulley A34, and sealing rolling door 391 is rolled on the outer side of winding roller 39, through the linkage between winding roller 39 and conveying roller 31 in feeding control mechanism 3, both the transportation of nano thermal insulation material and the opening and closing of sealing rolling door 391 can be completed, and the functionality is strong.

[0022] In this embodiment, specifically, the nano-insulating material is conveyed to each conveying roller 31 through an external conveyor belt. During the rotation, the conveying roller 31 drives the coaxially fixed gear 32 to rotate, and drives other conveying rollers 31 to rotate synchronously through the toothed belt 36. Finally, the winding roller 39 is driven to rotate through the cooperation between the pulley A34, the pulley B38 and the transmission belt 37. The rotation of the winding roller 39 realizes the opening and closing of the sealed rolling door 391, thereby controlling whether the internal environment of the spray box 1 is closed or open, and moves synchronously with the conveying roller 31 to cooperate to complete the feeding and unloading of the nano-insulating material. Among them, the rotation of the winding roller 39 is controlled by an external motor. It should be noted that the motor is a prior art, which is not shown in the figure and will not be described in detail.

[0023] like Figure 1-3As shown, in some embodiments, the spraying mechanism includes a sliding rod 2, which is slidably connected to a slide rail 12. A plurality of liquid spray heads 21 are detachably connected to the sliding rod 2, and the liquid spray heads 21 are connected to a liquid storage tank 11 through pipelines. By providing a plurality of liquid spray heads 21, the damage of a single liquid spray head 21 can be effectively avoided, which affects the normal progress of the coating spraying, ensures the working efficiency of the coating spraying, and to a certain extent, the setting of a plurality of liquid spray heads 21 improves the spraying efficiency.

[0024] As Figure 1-3 shown, in some embodiments, at least two limiting clamping wheels 33 are coaxially and movably connected to the conveying rollers 31 at both ends. Through the adjustable setting of the limiting clamping wheels 33, it is convenient to continue to limit both sides of the material, preventing the material from deviating greatly in position during transportation, which causes the quality of the material coating spraying to decline.

[0025] As Figure 1-3 shown, in some embodiments, a counterweight 392 is integrally and fixedly connected to the inner bottom of the sealing rolling door 391. Slots for inserting the sealing rolling door 391 are provided on both sides of the spraying box 1. Through the setting of the counterweight 392 in the sealing rolling door 391, the verticality of the sealing rolling door 391 is ensured as much as possible, preventing it from generating wrinkles during movement and getting the spraying liquid stuck in the gaps between the wrinkles, which is convenient for subsequent regular cleaning.

[0026] As Figure 1-3 shown, in some embodiments, the toothed belts 36 on adjacent gears 32 are arranged staggeredly. Through the staggered arrangement of the toothed belts 36, the synchronous movement between the conveying rollers 31 is ensured, eliminating the need to set up a tensioning wheel, saving space and ensuring the horizontal and stable transportation of the material.

[0027] As Figure 1-3 shown, in some embodiments, the slide rail 12 is arranged between two winding rollers 39, ensuring that the liquid spray heads 21 of the spraying mechanism do not spray a large amount of spraying liquid onto the sealing rolling door 391 and restricting the movement range of the positions of the liquid spray heads 21.

[0028] As Figure 1-3 shown, in some embodiments, the sliding rod 2 has a "C" - shaped structure. Both parallel segments are slidably connected to the slide rail 12, and its horizontal segment is connected to the two parallel segments by screws. Through the adjustable setting of the sliding rod 2 itself, the height of the liquid spray head 21 can be freely adjusted according to the thickness of the material, making this component applicable to the coating spraying of more nano - thermal insulation materials.

[0029] As Figure 1-3As shown, in some embodiments, both sides of the sealing rolling door 391 are slidably connected to the inner wall of the spray box 1, and the sliding of both sides of the sealing rolling door 391 is restricted to ensure the stability of the movement of the sealing rolling door 391. In conjunction with the counterweight block 392, the sealing rolling door 391 will not shake, thereby ensuring the sealing of the entire spray box 1 when the sealing rolling door 391 is closed.

[0030] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
