Description

Technical Field

[0001] This utility model relates to the field of fire-retardant coating processing technology, specifically a filling machine for fire-retardant coating processing. Background Technology

[0002] In the industrial production of fire-retardant coatings, the emergence and upgrading of filling machines are a result of adapting to product characteristics, industry needs, and regulatory requirements. Due to the presence of flame-retardant particles leading to high viscosity, easy stratification of components, and the flammability of some raw materials, specialized equipment is needed to solve the clogging and pollution problems of traditional low-viscosity filling machines. At the same time, with the growth of market demand (from less than 500,000 tons in 2010 to more than 2 million tons in 2024), filling machines have evolved from manual to intelligent automation to improve efficiency (daily capacity of 10,000-20,000 barrels with an error of ±0.5%). They also need to comply with environmental protection (reducing VOC emissions) and safety (explosion-proof design) regulations. Filling is the key to ensuring quality (avoiding stratification, accurate measurement, and preventing pollution), meeting storage and transportation requirements (adapting to transport packaging and extending shelf life), complying with compliant transactions (measuring quantitative packaging standards and ensuring fair pricing), and improving construction convenience (facilitating measurement and preventing secondary pollution). It is a necessary link connecting production and application.

[0003] Some existing filling machines cannot completely seal the discharge port in time after filling. Due to the high viscosity of the fire retardant coating, there will be a delayed dripping phenomenon, which causes the coating to drip onto the storage tank or conveyor belt, resulting in coating waste and pollution of the working environment. Utility Model Content

[0004] Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a filling machine for fire-retardant coating processing. This filling machine can effectively prevent the coating from being discharged from the feed cylinder during the entire stroke of the valve ball closing, eliminating liquid leakage and problems such as overloading during filling due to leakage. It provides reliable leak-proof protection for the coating filling process and ensures the high efficiency and stability of the production process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a filling machine for processing fire-retardant coatings, comprising a support frame, wherein a leak-proof mechanism and a metering mechanism are provided on the support frame; The leak-proof mechanism includes a motor fixedly connected to the right side of the support frame. The output end of the motor is fixedly connected to a rotating rod 1 via a coupling. Rotating rods 2 rotatably pass through the left and right sides of the support frame. Synchronous pulleys are fixedly connected to the outer walls of the two rotating rods 2 and the rotating rod 1. Synchronous belts are fitted onto the outer walls of the corresponding two synchronous pulleys. There are two synchronous belts, which are symmetrically arranged about the support frame as the central axis. Turntables are fixedly connected to the ends of the two rotating rods 2 away from the synchronous pulleys. Offset shafts are fixedly connected to the sides of the two turntables that are close to each other. Hinged rods are rotatably connected to the outer walls of the two offset shafts. A stirring cylinder is fixedly connected inside the support frame. A feeding cylinder is connected to the bottom of the stirring cylinder. A connecting cylinder is connected to the outer wall of the feeding cylinder. A piston block is slidably connected to the inner wall of the connecting cylinder. A piston rod is fixedly connected to the piston block. The end of the piston rod away from the piston block slides to the outside of the piston block. The ends of the two hinged rods away from the offset shafts are hinged to the outer walls of the piston rod.

[0006] Preferably, a plurality of stirring rods are fixedly connected to the outer wall of the rotating rod, and all of the stirring rods are slidably connected to the inner wall of the stirring cylinder.

[0007] Preferably, the metering mechanism includes a fixed rod that is fixedly connected to the outer wall of the piston rod, and a connecting rod is fixedly connected to both the left and right ends of the fixed rod.

[0008] Preferably, each of the two connecting rods is hinged to a connecting rod two at the end away from the fixed rod one, the inner wall of the feed cylinder is provided with an expansion tube, the inside of the expansion tube is provided with a valve ball, and the inner diameter of the expansion tube is the same as the outer diameter of the valve ball.

[0009] Preferably, a second fixing rod is fixedly connected to the valve ball, the second fixing rod passes through the feed cylinder, and the second fixing rod is rotatably connected to the feed cylinder.

[0010] Preferably, the ends of the two connecting rods 2 that are away from the connecting rod 1 are respectively hinged to the left and right ends of the fixed rod 2, and the connecting cylinder is located above the valve ball.

[0011] Preferably, the top of the mixing drum is connected to a feed pipe, and the inner bottom wall of the support frame is fixedly connected to a roller frame, on which a filling barrel is placed, and the filling barrel is located below the feed cylinder.

[0012] Compared with the prior art, this utility model provides a filling machine for processing fire-retardant coatings, which has the following beneficial effects: 1. By incorporating a leak-proof mechanism, after the filling barrel is filled, when the piston rod drives the piston block away from the discharge cylinder, the inside of the connecting cylinder is under negative pressure. At this time, the fire retardant coating that is about to be discharged from the discharge cylinder can be drawn into the connecting cylinder. During the entire stroke of the valve ball closing, the coating is effectively prevented from being discharged from the discharge cylinder in advance, eliminating liquid leakage and problems such as overloading due to leakage. This provides a reliable leak-proof guarantee for the coating filling process and ensures the high efficiency and stability of the production process.

[0013] 2. Equipped with a metering mechanism, during filling of the filling barrel, paint can be discharged into the mixing drum in stages through the inlet pipe. When the hinge rod drives the piston block close to the discharge cylinder, it will drive the fixed rod one to move. With the cooperation of connecting rod one and connecting rod two, the fixed rod two will rotate. At this time, the valve ball is in a slow opening state, controlling the discharge speed of the discharge cylinder, thereby quantitatively filling the filling barrel. The anti-leakage mechanism and the metering mechanism work together so that when the valve ball opens, the piston block can squeeze and discharge the excess paint in the connecting cylinder. The two are linked to each other to ensure the consistency of the filling stroke. Attached Figure Description

[0018] Please see Figure 1-4 This utility model provides a technical solution for a filling machine for processing fire-retardant coatings: Example 1: A filling machine for processing fire-retardant coatings includes a support frame 1, on which a leak-proof mechanism 2 and a metering mechanism 3 are provided; The leak-proof mechanism 2 includes a motor 21 fixedly connected to the right side of the support frame 1. The output end of the motor 21 is fixedly connected to a rotating rod 22 via a coupling. Rotating rods 23 rotatably pass through the left and right sides of the support frame 1. Synchronous pulleys 24 are fixedly connected to the outer walls of the two rotating rods 23 and the rotating rod 22. Synchronous belts 25 are fitted onto the outer walls of the two synchronous pulleys 24. There are two synchronous belts 25, which are symmetrically arranged about the support frame 1. The drive motor 21 drives the two synchronous pulleys 24 to rotate, which in turn drives the rotating rods 23 to rotate synchronously with the two synchronous belts 25. Turntables 26 are fixedly connected to the ends of the two rotating rods 23 that are away from the synchronous pulleys 24. Offset shafts 27 are fixedly connected to the sides of the two turntables 26 that are close to each other. The outer walls of the two offset shafts 27 are rotatably connected to... The system includes a hinge rod 28 and a stirring cylinder 291 fixedly connected inside the support frame 1. A feeding cylinder 292 is connected to the bottom of the stirring cylinder 291, and a connecting cylinder 293 is connected to the outer wall of the feeding cylinder 292. A piston block 294 is slidably connected to the inner wall of the connecting cylinder 293, and a piston rod 295 is fixedly connected to the piston block 294. One end of the piston rod 295 away from the piston block 294 slides to the outside of the piston block 294. The ends of the two hinge rods 28 away from the deflection axis 27 are hinged to the outer wall of the piston rod 295. Several stirring rods 296 are fixedly connected to the outer wall of the rotating rod 22. The stirring rods 296 are slidably connected to the inner wall of the stirring cylinder 291. The stirring rods 296 will cause the coating inside the stirring cylinder 291 to tumble, preventing the coating from settling.

[0019] Example 2: Based on Example 1, the metering mechanism 3 includes a fixed rod 31 fixedly connected to the outer wall of the piston rod 295. Connecting rods 32 are fixedly connected to both the left and right ends of the fixed rod 31. Connecting rods 33 are hinged to the ends of the two connecting rods 32 away from the fixed rod 31. An expanding tube 36 is provided on the inner wall of the feeding cylinder 292. A valve ball 34 is provided inside the expanding tube 36. The inner diameter of the expanding tube 36 is the same as the outer diameter of the valve ball 34. The inner wall of the expanding tube 36 is slidably connected to the outer wall of the valve ball 34. The valve ball 34 is used to control the discharge speed of the feeding cylinder 292 and to meter the filling. A fixed rod 33 is fixedly connected to the valve ball 34. 5. Fixing rod 25 passes through the feeding cylinder 292 and is rotatably connected to the feeding cylinder 292. The ends of the two connecting rods 23 away from the connecting rod 1 32 are respectively hinged to the left and right ends of the fixing rod 25. The connecting cylinder 293 is located above the valve ball 34. The top of the mixing cylinder 291 is connected to the feed pipe 5. The inner bottom wall of the support frame 1 is fixedly connected to the roller frame 11. The filling barrel 4 is placed on the roller frame 11. The filling barrel 4 is located below the feeding cylinder 292. The roller frame 11 is used to assist in the transportation of the filling barrel 4 so that the filling barrel 4 can be effectively arranged for filling. At the same time, the feed pipe 5 is used to transport the coating into the mixing cylinder 291.

[0020] In practical use, this fire-retardant coating filling machine, equipped with a leak-proof mechanism 2, prevents a small amount of residual coating liquid from flowing out of the feed cylinder 292 after filling the filling barrel 4, even when the valve ball 34 is closed. This could lead to leakage or overfilling. At this point, the drive motor 21 can slowly rotate the first rotating rod 22. With the cooperation of the synchronous pulley 24 and synchronous belt 25, the second rotating rod 23 rotates synchronously with the first rotating rod 22, thereby rotating the two turntables 26. Due to the eccentric design of the offset shaft 27, the hinge rod 28 drives the piston rod 295 in a reciprocating motion, while the piston rod 295 drives the piston block 294 away from the piston. When the feeding cylinder 292 is in operation, the inside of the connecting cylinder 293 is under negative pressure. At this time, the fireproof coating that is about to be discharged from the feeding cylinder 292 can be drawn into the connecting cylinder 293. During the entire stroke of the valve ball 34 closing, the coating is effectively prevented from being discharged from the feeding cylinder 292 in advance, eliminating liquid leakage and problems such as overloading during filling due to leakage. This provides a reliable leak-proof guarantee for the coating filling process, ensuring the high efficiency and stability of the production process. When the motor 21 rotates, it will drive the stirring rod 296 to rotate, thereby intermittently stirring the coating inside the stirring cylinder 291 during the leak-proof protection process, preventing the stirring cylinder 291 from accumulating and settling after filling. With the quantitative mechanism 3 in place, when filling the filling barrel 4, the paint can be discharged into the mixing drum 291 in stages through the feed pipe 5. When the hinge rod 28 drives the piston block 294 to approach the discharge cylinder 292, it will drive the fixed rod 31 to move. With the cooperation of the connecting rod 32 and the connecting rod 33, the fixed rod 35 will rotate. At this time, the valve ball 34 will slowly open, controlling the discharge speed of the discharge cylinder 292, thereby quantitatively filling the filling barrel 4. The anti-leakage mechanism 2 and the quantitative mechanism 3 cooperate with each other, so that when the valve ball 34 is opened, the piston block 294 can squeeze and discharge the excess paint in the connecting cylinder 293. The two are linked together to ensure the consistency of the filling stroke.

[0021] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
