Description

Technical Field

[0001] This utility model relates to the field of flame retardant production technology, and in particular to a flame retardant feeding machine with automatic feeding function. Background Technology

[0002] Flame retardants, also known as fire-retardant agents, fire-resistant agents, or fire-retardant agents, are functional additives that impart flame-retardant properties to flammable polymers. They are mainly designed for flame retardancy of polymer materials and are used to prevent or delay the combustion of materials, especially polymer materials. They can extend the ignition time, making them difficult to ignite or self-extinguishing after ignition. The production and preparation of flame retardants may require multiple processes, such as raw material pretreatment, mixing, granulation, and drying. Feeding is an important step in this process, ensuring the continuity and stability of the raw materials in subsequent processes.

[0003] A search revealed that Chinese patent CN221343067U discloses a raw material feeding mechanism for producing flame retardants. Addressing the issue that manually pouring bagged flame retardant powder into the feeding cylinder is cumbersome and causes pollution due to the powder being stirred up, this new mechanism automatically feeds the flame retardant. This addresses the shortcomings of existing technologies that require automatic feeding of bagged flame retardant powder.

[0004] The aforementioned feeding mechanism facilitates automatic feeding of flame retardants during use. However, during the mixing and processing of flame retardants, a large amount of flame retardant needs to be added into the mixing tank. The mixing tank is large in volume, and the flame retardant piled together is heavy. Furthermore, the feeding port is usually located at the top of the tank, requiring manual handling to move large quantities of flame retardant to the top of the tank before feeding. Prolonged handling can easily cause arm pain and fatigue for the operator, thereby reducing the feeding efficiency of the flame retardant. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flame retardant feeding machine with automatic feeding function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a flame retardant feeder with automatic feeding function, including a mounting frame, with stabilizing frames fixedly connected to both sides of the mounting frame, a sliding groove opened on one side of the mounting frame, a first stepper motor fixedly installed on one side of the mounting frame, a screw fixedly connected to the output end of the first stepper motor, a slider slidably connected inside the sliding groove, a moving block fixedly connected to the lower surface of the slider, the moving block being threadedly connected to the outside of the screw, and a feeding component provided on the lower surface of the moving block.

[0011] As a further description of the above technical solution:

[0012] The inside of the rope take-up reel is provided with connecting ropes, and one end of each of the multiple connecting ropes is provided with a feeding frame. The lower surface of the feeding frame is provided with an anti-clogging component, which includes a feeding tube that is connected through to the lower surface of the feeding frame.

[0013] As a further description of the above technical solution:

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model, through the setting of the feeding component, adds a function to the flame retardant feeding machine to facilitate automatic feeding, thereby automatically transporting large quantities of flame retardant for feeding. It eliminates the need for manual handling of large quantities of flame retardant to the top of the mixing tank before feeding, reducing the operator's arm soreness and fatigue, thus helping to improve feeding efficiency and speed up the processing progress.

[0021] 2. By incorporating an anti-clogging component, this utility model enhances the flame retardant feeding machine by preventing clogging during the feeding process. This helps reduce the clumping caused by the adhesion of flame retardants, which can lead to blockage of the feeding pipe opening. This, in turn, improves feeding efficiency and enhances the stability and continuity of the feeding process. Attached Figure Description

When the slider 6 slides inside the sliding groove 3, it facilitates the improvement of the stability of the moving block 7 during movement.

[0033] As attached Figure 4 As shown, the feeding assembly includes two mounting frames 8, which are fixedly connected to the lower surface of the moving block 7. A rotating rod 9 is rotatably connected inside the mounting frame 8, and two rope take-up reels 10 are fixedly connected to the outside of the rotating rod 9. A second stepper motor 11 is fixedly installed on one side of one of the mounting frames 8, and one end of one of the rotating rods 9 is fixedly connected to the output end of the second stepper motor 11. The rotating rod 9 facilitates the connection of the two rope take-up reels 10.

[0034] As attached Figure 1As shown, one end of one rotating rod 9 is fixedly connected to a large synchronous pulley 12, and one end of the other rotating rod 9 is fixedly connected to a small synchronous pulley 13. A synchronous belt 14 is provided between the small synchronous pulley 13 and the large synchronous pulley 12. A connecting rope 15 is provided inside the rope take-up reel 10. A feeding frame 16 is provided at one end of the multiple connecting ropes 15. The connection of the large synchronous pulley 12, the small synchronous pulley 13 and the synchronous belt 14 facilitates the simultaneous rotation of the two rotating rods 9. The connecting ropes 15 facilitate the pulling of the feeding frame 16.

[0035] As attached Figure 5 As shown, the lower surface of the feeding frame 16 is provided with an anti-blocking component, which includes a feeding pipe 17. The feeding pipe 17 is connected to the lower surface of the feeding frame 16. The inner wall of the feeding pipe 17 is provided with a slot 18. The feeding pipe 17 facilitates the passage of materials, and the slot 18 facilitates the installation of the material blocking plate 28.

[0036] As attached Figure 6 As shown, a protective frame 19 is fixedly connected inside the feeding frame 16. A rotating rod 20 is rotatably connected to the lower surface of the protective frame 19. A spiral blade 21 is fixedly connected to the outside of the rotating rod 20. A drive motor 22 is fixedly installed on one side of the feeding frame 16. A mounting rod 23 is fixedly connected to the output end of the drive motor 22. A first bevel gear 24 is fixedly connected to one end of the mounting rod 23. A second bevel gear 25 is fixedly connected to one end of the rotating rod 20. The first bevel gear 24 and the second bevel gear 25 are meshed. The protective frame 19 helps to protect the first bevel gear 24 and the second bevel gear 25.

[0037] As attached Figure 7 As shown, a hydraulic cylinder 26 is fixedly installed on the lower surface of the feeding frame 16. A connecting rod 27 is fixedly connected to the output end of the hydraulic cylinder 26. A material blocking plate 28 is fixedly connected to one end of the connecting rod 27. The material blocking plate 28 can block the material, thereby facilitating the flexible opening and closing of the feeding pipe 17.

[0038] Working principle: In use, the second stepper motor 11 is first driven to place the feeding frame 16 on the ground. Then, the flame retardant material to be processed is put into the feeding frame 16. Then, the second stepper motor 11 is turned on, which drives one of the rotating rods 9 to rotate. The rotating rod 9 drives the corresponding small synchronous wheel 13 to rotate. The small synchronous wheel 13, connected by the synchronous belt 14, drives the large synchronous wheel 12 to rotate, which in turn drives the other rotating rod 9 to rotate. The two rotating rods 9 drive the two rope take-up discs 10 to rotate. When the rope take-up discs 10 rotate, the connecting rope 15 is taken up, which makes the feeding frame 16 rise. Then, the first stepper motor 4 is turned on, which drives the screw 5 to rotate. The screw 5 drives the moving block 7 to move, which makes the slider 6 slide inside the slide groove 3. Then, the moving block 7 indirectly drives the feeding frame 16 to move above the mixing tank for feeding.

[0039] During material feeding, the hydraulic cylinder 26 is activated, causing the output end of the hydraulic cylinder 26 to move the connecting rod 27. This causes the connecting rod 27 to slide the material blocking plate 28 inside the slot 18, thereby opening one end of the feeding pipe 17. Then, the drive motor 22 is activated, causing the output end of the drive motor 22 to rotate the mounting rod 23. This causes the mounting rod 23 to rotate the first bevel gear 24. Through the meshing of the first bevel gear 24 and the second bevel gear 25, the second bevel gear 25 is easily rotated. This causes the second bevel gear 25 to rotate the rotating rod 20 and the spiral blade 21, thereby facilitating the material conveying process, improving the continuity of the conveying process, and reducing the phenomenon of material accumulating at the opening of the feeding pipe 17 due to agglomeration.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
