Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, specifically to a pre-processing equipment for nonwoven fabric production. Background Technology

[0002] Nonwoven fabric processing is the process of transforming fibers into nonwoven fabrics through mechanical, thermal, and chemical methods, including steps such as opening, web formation, and reinforcement. Fiber blending plays a crucial role in this process. By mixing fibers of different types or properties (such as polypropylene, polyester, and natural fibers) in specific proportions, the properties of the nonwoven fabric, such as softness, strength, and absorbency, can be adjusted to meet the needs of various applications (such as medical, hygiene, filtration, and industrial applications). Fiber blending not only optimizes the physical properties of the product but also endows the nonwoven fabric with diverse functionalities.

[0003] However, existing methods for mixing fibers are ineffective, resulting in long preparation times and low overall processing efficiency. To address these issues, the inventors propose a pre-processing equipment for non-woven fabric production. Utility Model Content

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figure 1-7As shown, this utility model provides a pre-processing equipment for non-woven fabric production, including a base 1 and a mixing tank 13. The mixing tank 13 can mix polypropylene, polyester, natural fibers, and other fibers required for processing non-woven fabric. The mixing tank 13 is installed above the base 1. A symmetrically distributed support frame 11 is fixedly installed at the top of the base 1 for fixed support. A rotating shaft 12 is rotatably installed inside the support frame 11. Two rotating shafts 12 are fixedly installed on both sides of the mixing tank 13. A first rotating rod 2 and a second rotating rod 23 are rotatably inserted into both sides of the mixing tank 13. The rotation of the second rotating rod 23 drives the stirring frame 21 to rotate. The stirring frame 21 is installed on the outside of the first rotating rod 2. A stirring blade 22 is fixedly installed on the inner wall of the stirring frame 21. A stirring assembly 24 is fixedly mounted on the outer side of the second rotating rod 23. The stirring assembly 24 and the stirring blade 22 are arranged alternately. The stirring assembly 24 and the stirring blade 22 can mix and stir the fibers. A transmission rod 25 is rotatably mounted on the outer side of the mixing barrel 13. A third rotating rod 26 is rotatably mounted on the outer side of the end of the mixing barrel 13 away from the first rotating rod 2. The transmission rod 25 and the third rotating rod 26 are connected by a synchronous pulley and a synchronous belt. A first gear 27 is fixedly mounted on the outer side of the third rotating rod 26. A second gear 28 is fixedly mounted on the outer side of the end of the second rotating rod 23 close to the first gear 27. The first gear 27 and the second gear 28 mesh with each other, so that the rotation of the transmission rod 25 drives the first rotating rod 2 and the second rotating rod 23 to rotate in opposite directions.

[0023] The mixing tank 13 has a cavity 3 inside. An air inlet pipe 31 and an air outlet pipe 32 are fixed on both sides of the mixing tank 13 respectively. Both the air inlet pipe 31 and the air outlet pipe 32 are connected to the cavity 3. A connector 33 is fixed at one end of the air inlet pipe 31 and the air outlet pipe 32.

[0024] By adopting the above technical solution, hot air is injected into the cavity 3 through the air inlet pipe 31. The hot air can heat the fibers in the mixing barrel 13, thereby removing the moisture from the fibers and preventing mold growth in subsequent processing.

[0025] The transmission rod 25 and the first rotating rod 2 are connected by a synchronous pulley and a synchronous belt.

[0026] By adopting the above technical solution, the transmission rod 25 rotates, causing the first rotating rod 2 to rotate.

[0027] The bottom of the base 1 is fitted with mounting holes 29 arranged in a rectangular pattern.

[0028] By adopting the above technical solution, the mounting hole 29 can facilitate the installation and fixation of the entire device.

[0029] The top of the mixing tank 13 is fixed with symmetrically distributed guide plates 34.

[0030] By adopting the above technical solution, the guide plate 34 can pour out the fibers in the mixing tank 13.

[0031] One of the support frames 11 has a fixed frame 16 fixed on its outer side. A worm gear 17 is rotatably mounted inside the fixed frame 16. A worm wheel 18 is fixed on the outer side of the rotating shaft 12 on one side of the worm gear 17. The worm gear 17 and the worm wheel 18 mesh with each other.

[0032] By adopting the above technical solution, the worm 17 rotates, driving the meshing worm wheel 18 to rotate.

[0033] A turntable 19 is rotatably mounted on the top of the fixed frame 16, and the end of the turntable 19 meshes with the worm gear 17.

[0034] By adopting the above technical solution, the turntable 19 rotates, causing the worm gear 17 to rotate.

[0035] A fixing plate 14 is fixedly provided on the outside of the mixing tank 13. A motor 15 is installed on the outside of the fixing plate 14. The output end of the motor 15 is inserted through the fixing plate 14 and fixedly connected to the transmission rod 25.

[0036] By adopting the above technical solution, the output end of motor 15 rotates, driving the transmission rod 25 to rotate.

[0037] Working principle: First, the fibers required for processing non-woven fabric, such as polypropylene, polyester, and natural fibers, are put into the mixing tank 13. Then, the motor 15 is started, causing it to operate. The output of the motor 15 rotates, driving the transmission rod 25 to rotate. The rotation of the transmission rod 25, through the synchronous pulley and synchronous belt, causes the first rotating rod 2 to rotate. The rotation of the first rotating rod 2 drives the stirring frame 21 and the stirring blade 22 to rotate. Simultaneously, the rotation of the transmission rod 25, through the synchronous pulley and synchronous belt, causes the third rotating rod 26 to rotate. The rotation of the third rotating rod 26 drives the first gear 27 to rotate. The rotation of the first gear 27 drives the meshing second gear 28 to rotate. The rotation of the second gear 28 drives the second rotating rod 23 to rotate. The rotation of the second rotating rod 23 drives the stirring assembly 24 to rotate. By simultaneously rotating the stirring blade 22 and the stirring assembly 24, the fibers are stirred. Since they rotate in opposite directions, the mixing efficiency is improved, thereby increasing the processing efficiency.

[0038] Meanwhile, during the mixing process, the air inlet pipe 31 is connected to external hot air via the connector 33, and the air outlet pipe 32 is connected to external waste gas collection equipment via the connector 33. The air inlet pipe 31 injects hot air into the cavity 3, which heats the fibers in the mixing barrel 13, removing moisture and preventing mold growth in subsequent processing. After the mixing preparation is completed, the turntable 19 is rotated, causing the worm gear 17 to rotate. The worm gear 17 rotates, causing the meshing worm wheel 18 to rotate. The worm wheel 18 rotates, causing one of the rotating shafts 12 to rotate. One of the rotating shafts 12 rotates the mixing barrel 13 and the other rotating shaft 12, allowing the mixing barrel 13 to rotate within the support frame 11, thereby discharging the fibers from the mixing barrel 13.

[0039] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
