Description

Technical Field

[0001] The utility model relates to the technical field of fire retardant coating production, in particular to a feeding device for the production of non-expansion fire retardant coating. Background Art

[0002] Non-intumescent fire-retardant coatings are specialized coatings that form a fire-resistant protective layer without expanding at high temperatures. They are primarily composed of inorganic insulating materials, flame retardants, fillers, and binders. When exposed to fire, they utilize their excellent thermal insulation properties and the heat absorption generated by the evaporation and decomposition of some components to block and dissipate the heat transferred to the substrate, thereby delaying the steel structure from reaching its critical temperature. Non-intumescent fire-retardant coatings are generally suitable for buildings with high fire protection requirements. Their advantages include being non-flammable, non-toxic, age-resistant, and highly durable.

[0003] The current production process for non-intumescent fire-retardant coatings primarily involves raw material selection and proportioning, mixing and stirring, chemical reaction and curing, screening and blending, and coating testing and packaging. Raw materials such as inorganic flame retardants, resins, and fillers that meet national standards are selected and mixed and stirred in specific proportions to ensure uniform mixing. The mixed materials are then fed into a reactor where the coating cures through chemical reactions and crystal growth. The cured coating undergoes screening to control particle size and is blended with specific organic additives to enhance its plasticity and durability.

[0004] Among them, some raw materials of non-expanding fire retardant coatings are in powder form and are generally transported in woven bags. However, when loading the raw materials, the woven belt needs to be shaken and squeezed, but this will still cause the powder to float in the air. There are more raw materials remaining in the woven belt, which will not only cause harm to the workers' health, but also pollute the environment. Utility Model Content

[0039] When the loading component is working, the linear motor 13 also starts working, driving the shell 9 to reciprocate through the fixed plate 14. The reciprocating motion of the shell 9 will drive the loading component to move, causing the braided belt inside the loading component to vibrate, thereby reducing the residue of powdered raw materials in the braided belt.

Then the output end of the electric push rod 19 drives the connecting plate 20 to move, thereby changing the position of the second support shaft 16 through the slider 18 on the second support shaft 16 and the slide groove 17. At this time, because the first support shaft 15 is fixedly connected to the shell 9, and the movable plate 24 on the first support shaft 15 is fixedly connected to the support shaft, the movable plate 24 located on the first support shaft 15 is rotatably connected to the support plate 23, so when the electric push rod 19 pushes the second support shaft 16 to move, the movable plate 24 located on the second support shaft 16 is slidably connected to the second support shaft 16 and the movable plate 24 located on the second support shaft 16 and the support plate 23 set on the placement box 21 rotate, so when the second support shaft 16 moves, the placement box 21 will rotate, so that the corner with the notch 22 passes through the material opening 11 downward, thereby achieving the purpose of loading.

[0050] The following is a detailed description of the working principle of the feeding device for the production of non-expanding fire retardant coatings.

[0051] like Figures 1-7As shown, when loading is required, the cover 10 is opened, and the woven bag containing the dusty raw materials is placed inside the loading component, and then the cover 10 is closed and the control component is started. The control component will destroy the structure of the woven belt to allow the dust to escape, and then the loading component starts to work, and the powdery raw materials in the woven bag are fed into the feeding pipe 5. At this time, the moving component starts to work and drives the loading component to move back and forth, so that the powdery raw materials are vibrated, thereby reducing the residual raw materials in the woven belt. At the same time, the drive motor 4 can be controlled to work and drive the auger 6 to rotate, thereby achieving the purpose of loading. At the same time, such a setting can reduce the probability of powdery raw materials escaping, thereby reducing the harm to the workers' bodies and protecting the environment. When the loading component is working, the linear motor 13 also starts to work, and drives the shell 9 to reciprocate through the fixed plate 14. The reciprocating movement of the shell 9 will drive the loading component to move, causing the woven belt inside the loading component to vibrate, thereby reducing the residual powdery raw materials in the woven belt. When loading is required, the braided belt is placed in the placement box 21, and then the control component is used to destroy the structure of the braided belt, so that a hole is formed in the corner of the braided belt located at the notch 22 of the placement box 21. Then the output end of the electric push rod 19 drives the connecting plate 20 to move, thereby changing the position of the second support shaft 16 through the slider 18 on the second support shaft 16 and the slide groove 17. At this time, because the first support shaft 15 is fixedly connected to the shell 9, and the movable plate 24 on the first support shaft 15 is fixedly connected to the support shaft, the movable plate 24 located on the first support shaft 15 is rotatably connected to the support plate 23, so when the electric push rod 19 pushes the second support shaft 16 to move, the movable plate 24 located on the second support shaft 16 is slidably connected to the second support shaft 16 and the movable plate 24 located on the second support shaft 16 and the support plate 23 set on the placement box 21 rotate, so when the second support shaft 16 moves, the placement box 21 will rotate, so that the corner with the notch 22 passes through the material opening 11 downward, thereby achieving the purpose of loading. When the structure of the braid needs to be destroyed, the push plate 26 is pressed, and the pressure spring is in a compressed state. At this time, the blade 27 will move toward the notch 22 of the placement box 21 until the blade 27 is inserted into the braid to destroy the structure of the braid. Then the push plate 26 is released, and the push plate 26 is reset under the action of the elastic spring 28. At this time, the electric push rod 19 starts working to drive the placement box 21 to rotate, thereby achieving the purpose of loading. When the placement box 21 is rotating, a part of the raw materials will adhere to the inner wall of the shell 9. When the feeding is completed, the vacuum cleaner can be turned on at this time. The powdered raw materials will enter the inside of the vacuum cleaner through the hose 29 and the one-way valve, so that some of the raw materials can be collected and the cost can be reduced. The stability of the connection between the fixed plate 14 and the shell 9 can be enhanced by providing a reinforcing rib 30 at the connection between the fixed plate 14 and the shell 9.By providing the control panel 31 , the working states of the drive motor 4 , the vacuum cleaner and the electric push rod 19 can be adjusted in a timely manner, thereby improving working efficiency.
