Description

Technical Field

[0001] This utility model relates to the field of fire-retardant coating production technology, specifically to a feeding device for fire-retardant coating production. Background Technology

[0002] In the production of fire-retardant coatings, the feeding device is a crucial piece of equipment for accurately conveying powdered raw materials such as flame retardants and fillers to the mixing system. However, due to their inherent characteristics, powdered materials are prone to clogging within the device: friction and electrostatic forces between material particles cause them to adhere and aggregate; simultaneously, changes in ambient temperature and humidity can alter the material's flowability. When these factors work together, the material easily forms an arched structure within the feeding channel, a phenomenon known as "bridging." This phenomenon leads to channel blockage, preventing continuous and stable material discharge, which not only affects production efficiency but may also cause deviations in the coating composition ratio due to unstable feeding amounts, thus impacting the performance and quality of the fire-retardant coating. Therefore, improvements to the existing feeding device are needed to address these clogging problems.

[0003] Traditional fire-retardant coating production feeding mechanisms rely on gravity conveying. Powdered raw materials, such as flame retardants and fillers, are first loaded into a top hopper. The bottom of the hopper is cone-shaped or funnel-shaped to guide the material towards the discharge port. The material then slides down a sloped or vertical channel connected to the bottom under its own weight into the mixing equipment below. Traditional mechanisms primarily use vibrators or manual tapping to prevent material accumulation.

[0004] Due to interparticle friction, electrostatic forces, or environmental factors, arched structures can form and block the channel during material transport. Furthermore, the response to manual knocking to break up the bridging is not timely, leading to material accumulation and the inability to be discharged smoothly. Utility Model Content

[0014] A further improvement of this utility model is that a guide pipe is fixedly connected to the bottom of the feeding box, and the guide pipe is inclined downward from left to right.

[0015] A further improvement of the present invention is that the anti-bridging mechanism includes a bracket, which is fixedly connected to the right side of the support base.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. This utility model provides a feeding device for fireproof coating production. By cutting open the material bag and placing it into the feeding box, and closing the sealing door, the shaking feeding mechanism and the drive mechanism are activated simultaneously. The shaking feeding mechanism shakes the material bag, thereby shaking the material out of the bag.

[0020] 2. This utility model provides a feeding device for fire-retardant coating production. After the material bag is cut open and placed on the support net, the sealing door is closed. The drive motor is started to drive the turntable to rotate. The rotation of the turntable causes the connecting rod to swing. The angle between the connecting rod and the horizontal plane changes periodically. The distance between the support net and the drive motor also changes back and forth, thereby shaking the material bag. Since pouring powdery materials usually raises a lot of dust, the sealing door can reduce dust during operation. The combination of the shaking feeding mechanism and the sealing door can reduce dust diffusion, protect personnel health, and balance efficiency and environmental protection.

[0021] 3. This utility model provides a feeding device for fire-retardant coating production. The material shaken off is transported to the anti-bridging mechanism through a guide pipe. A stepper motor is started to drive the rotating shaft to rotate, which in turn drives the impeller to rotate. The material falls between the adjacent blades of the impeller due to gravity. Since the included angle between the adjacent blades is the same, the material that can be contained inside is also fixed. By setting the number of rotations of the impeller, the device can achieve quantitative feeding. The rotating shaft drives the second pulley to rotate, and the second pulley drives the first pulley to rotate through the lifting frame. The first pulley drives the worm gear to rotate, which in turn drives the turbine to rotate. The turbine drives the stirring rod to rotate, thereby stirring the material in the transfer box and preventing bridging, which would affect the material conveying. Attached Figure Description

[0034] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figures 1-5 As shown, this utility model has the following three specific embodiments.

[0036] Example 1

[0037] This utility model provides a feeding device for the production of fire-retardant coatings, such as... Figure 1As shown, it includes a base 11, a support base 13 fixedly connected to the top of the base 11, a support column 12 fixedly connected to the bottom of the support base 13, a support leg 14 fixedly connected to the top of the support base 13, a feeding box 15 fixedly connected to the top of the support leg 14, and a sealing door 16 hinged to the side of the feeding box 15.

[0038] It also includes a vibrating feeding mechanism 2, an anti-bridging mechanism 3, a quantitative feeding mechanism 4, and a drive mechanism 5;

[0039] The shaking feeding mechanism 2 is located inside the feeding box 15 and is used to shake the materials out of the package;

[0040] The anti-bridging mechanism 3 is located at the bottom of the shaking feeding mechanism 2 to break the bridging phenomenon of materials and prevent materials from accumulating inside the device.

[0041] The quantitative feeding mechanism 4 is located at the bottom of the anti-bridging mechanism 3 and is used for quantitative feeding;

[0042] The drive mechanism 5 is used to simultaneously drive the anti-bridging mechanism 3 and the quantitative feeding mechanism 4.

[0043] In this embodiment, the material bag is cut open and placed inside the feeding box 15, and the sealing door 16 is closed. Then, the shaking feeding mechanism 2 and the drive mechanism 5 are started simultaneously. The shaking feeding mechanism 2 shakes the material bag to shake the material out of the bag. Since the powdery material inside the device may form an arched structure that blocks the channel due to interparticle friction, static electricity, or environmental factors, the material cannot be discharged smoothly. The drive mechanism 5 is started to drive the anti-bridging mechanism 3 to rotate, thereby breaking the arched structure and preventing the material from blocking. The drive mechanism 5 drives the quantitative feeding mechanism 4 to work, thereby realizing the quantitative output of the material.

[0044] Example 2

[0045] The difference from Embodiment 1 is that this embodiment discloses a shaking feeding mechanism 2;

[0046] like Figure 2 As shown, preferably, the vibrating feeding mechanism 2 includes a support net 22, which is movably connected to the inside of the feeding box 15. The front and rear sides of the inner wall of the feeding box 15 are provided with sliding grooves 21. The front and rear sides of the support net 22 are fixedly connected with sliders, which are disposed inside the sliding grooves 21 and slidably connected thereto. The right side of the support net 22 is fixedly connected with a hinge block 23, and a connecting rod 24 is hinged inside the hinge block 23. The inside of the feeding box 15 is fixedly connected with a drive motor 26, and the output end of the drive motor 26 is fixedly connected with a turntable 25. The end of the connecting rod 24 is hinged to the turntable 25 away from the center.

[0047] A guide pipe 27 is fixedly connected to the bottom of the feeding box 15. The guide pipe 27 is inclined downward from left to right.

[0048] In this embodiment, the material bag is cut open and placed on the support net 22, and then the sealing door 16 is closed. The drive motor 26 is started to drive the turntable 25 to rotate. The rotation of the turntable 25 causes the connecting rod 24 to swing. The angle between the connecting rod 24 and the horizontal plane changes periodically, and the distance between the support net 22 and the drive motor 26 also changes back and forth, thereby shaking the material bag. Since a lot of dust is usually raised when pouring powdery materials, the sealing door 16 is closed to seal the device, which can reduce dust during operation. The combination of shaking the feeding mechanism 2 and sealing door 16 can reduce dust diffusion, protect personnel health, and balance efficiency and environmental protection.

[0049] Example 3

[0050] The difference from Embodiment 2 is that this embodiment discloses an anti-bridging mechanism 3, a quantitative feeding mechanism 4, and a driving mechanism 5;

[0051] like Figures 3-5 As shown, preferably, the anti-bridging mechanism 3 includes a bracket 32, which is fixedly connected to the right side of the support base 13. A transfer box 31 is fixedly connected inside the bracket 32. A rotating block 33 is rotatably connected to the bottom of the transfer box 31. A stirring rod 34 is fixedly connected inside the rotating block 33. A turbine 35 is fixedly connected to the outside of the rotating block 33. A worm gear 36 is engaged on the left side of the turbine 35. Support plates 37 are provided on the left and right sides of the worm gear 36. The worm gear 36 is rotatably connected inside the support plates 37.

[0052] The quantitative feeding mechanism 4 includes a quantitative feeding box 41, which is located at the bottom of the rotating block 33. The rotating block 33 is rotatably connected to the top of the quantitative feeding box 41. An ascending frame 42 is fixedly connected to the bottom of the quantitative feeding box 41. A rotating shaft 43 is rotatably connected inside the quantitative feeding box 41. An impeller 44 is fixedly connected to the surface of the rotating shaft 43. A feeding port 45 is fixedly connected to the bottom of the quantitative feeding box 41. A support plate 37 is fixedly connected to the top of the quantitative feeding box 41.

[0053] The drive mechanism 5 includes a stepper motor 54, which is fixedly connected to the back of the quantitative feeding box 41. The output end of the stepper motor 54 is fixedly connected to the axis of the rotating shaft 43. A pulley 51 is fixedly connected to the end of the worm gear 36, and a pulley 53 is fixedly connected to the end of the rotating shaft 43. A belt 52 is movably connected to the surfaces of pulley 51 and pulley 53. The pulley 51 is connected to the pulley 53 via the belt 52.

[0054] In this embodiment, the material that has been shaken off is transported to the anti-bridging mechanism 3 through the guide pipe 27. The stepper motor 54 is started to drive the rotating shaft 43 to rotate, which in turn drives the impeller 44 to rotate. The material falls between the adjacent blades of the impeller 44 due to gravity. Since the included angle between the adjacent blades is the same, the material that can be contained inside is also fixed. By setting the number of rotations of the impeller 44, the device can achieve quantitative feeding. The rotating shaft 43 drives the pulley 2 53 to rotate. The pulley 2 53 then drives the pulley 1 51 to rotate through the riser frame 42. The pulley 1 51 then drives the worm gear 36 to rotate, which in turn drives the turbine 35 to rotate. The turbine 35 then drives the stirring rod 34 to rotate, thereby stirring the material in the transfer box 31 and preventing bridging, which would affect the material conveying.

[0055] The working principle of this utility model is as follows.

[0056] After the material bag is cut open and placed on the support net 22, the sealing door 16 is closed. The drive motor 26 is then activated to rotate the turntable 25. The rotation of the turntable 25 causes the connecting rod 24 to swing, and the angle between the connecting rod 24 and the horizontal plane changes periodically. The distance between the support net 22 and the drive motor 26 also changes continuously, thus shaking the material bag. Since pouring powdery materials usually raises a lot of dust, closing the sealing door 16 reduces dust during operation. The combination of the shaking feeding mechanism 2 and the sealing door 16 reduces dust diffusion, protecting personnel health and balancing efficiency and environmental protection. The shaken material is then transported to the anti-collision area via the guide pipe 27. Inside the bridge mechanism 3, the stepper motor 54 drives the rotating shaft 43 to rotate, which in turn drives the impeller 44 to rotate. Due to gravity, the material falls between the adjacent blades of the impeller 44. Since the included angle between the adjacent blades is the same, the amount of material that can be contained inside is also fixed. By setting the number of rotations of the impeller 44, the device can achieve quantitative feeding. The rotating shaft 43 drives the pulley 2 53 to rotate. The pulley 2 53 then drives the pulley 1 51 to rotate through the lifting frame 42. The pulley 1 51 then drives the worm gear 36 to rotate, which in turn drives the turbine 35 to rotate. The turbine 35 then drives the stirring rod 34 to rotate, thereby stirring the material in the transfer box 31 and preventing bridging, which would affect the material conveying.

[0057] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. The selection and detailed description of these embodiments in this specification are intended to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
