Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric treatment technology, specifically to a humidification pretreatment device for tear-resistant nonwoven fabric. Background Technology

[0002] Nonwoven fabric, a type of fabric formed without spinning and weaving, is widely used in many fields such as medical and health care, home decoration, and industrial packaging due to its lightweight, softness, breathability, and environmental friendliness. However, during production, storage, and transportation, nonwoven fabric is susceptible to environmental humidity, which can cause changes in its fiber structure, leading to problems such as hardening, brittleness, and tearing, seriously affecting product quality and service life. Therefore, humidification pretreatment of nonwoven fabric is particularly important. Humidification pretreatment can effectively increase the moisture content of nonwoven fabric, improve the bonding force between its fibers, and enhance its flexibility and tear resistance, thereby ensuring that nonwoven fabric maintains stable physical properties and performance under different environmental conditions.

[0003] Traditional nonwoven fabric humidification pretreatment technologies, such as simple spray humidification or soaking humidification, while able to improve the moisture content of nonwoven fabrics to some extent, have many drawbacks. On the one hand, these technologies often struggle to achieve uniform humidification, leading to significant differences in moisture content across different parts of the nonwoven fabric, affecting the overall product quality. On the other hand, the lack of effective tension control during humidification can easily cause stretching or deformation of the nonwoven fabric, thus reducing its tear resistance. Furthermore, traditional humidification technologies may suffer from low humidification efficiency, high energy consumption, and complex operation, increasing production costs and limiting the widespread application of nonwoven fabric humidification pretreatment technologies. These technological limitations severely impact the quality and market competitiveness of nonwoven fabric products. Therefore, developing a highly efficient, uniform, and tear-resistant nonwoven fabric humidification pretreatment device is particularly urgent. To this end, we propose a tear-resistant nonwoven fabric humidification pretreatment device. Utility Model Content

[0007] Preferably, an adjusting rod is threaded to the outer wall of one end of the bidirectional lead screw, and a second adjusting rod is threaded to the outer wall of the end of the bidirectional lead screw away from the adjusting rod. The second adjusting rod moves in the opposite direction to the adjusting rod, and the second adjusting rod and the outer wall of the top end of the adjusting rod are slidably connected to one end of the inner wall of the adjusting box.

[0008] Preferably, the outer wall of the adjusting rod and the second adjusting rod on opposite sides is provided with a spray pipe, and the outer wall of the adjusting rod and the second adjusting rod on the side near the spray pipe is provided with a second spray pipe. The second spray pipe is located directly below the spray pipe, and the output direction of the second spray pipe is opposite to that of the spray pipe.

[0009] Preferably, a water tank is provided at one end of the top of the workbench, a water pump is fixedly connected to the outer wall of one end of the water tank, a delivery hose is fixedly connected to the output end of one side of the water pump, the connector of the delivery hose away from the water pump is fixedly connected to the outer wall of one side of the adjusting rod, a second delivery hose is fixedly connected to the outer wall of the water pump away from the delivery hose, and the connector of the second delivery hose away from the water pump is fixedly connected to the outer wall of one side of the second adjusting rod.

[0010] Preferably, the bottom of the inner wall of the workbench is provided with a water tank, and a drain hole is provided on one side of the bottom of the water tank.

[0011] Preferably, an infeed roller is movably connected to the outer wall of one end of the worktable, a take-up roller is movably connected to the outer wall of the end of the worktable away from the infeed roller, and a servo motor is fixedly connected to the outer wall of the worktable near the take-up roller, with the servo motor's rotation shaft fixedly connected to a connecting shaft on one side of the take-up roller.

[0012] Compared with the prior art, this utility model provides a humidification pretreatment device for tear-resistant nonwoven fabric, which has the following beneficial effects:

[0013] 1. This tear-resistant nonwoven fabric humidification pretreatment device, compared to traditional nonwoven fabric humidification technologies such as simple spraying or soaking, often struggles to ensure uniform humidification, leading to significant differences in moisture content across different parts of the nonwoven fabric and affecting overall product quality. This application, through a unique structural design, achieves uniform humidification of the nonwoven fabric. The sliding plate in the device can move laterally, and the adjusting rod and second adjusting rod move in opposite directions under the drive of a bidirectional screw, adjusting the position of the spray pipe and the second spray pipe. This allows for humidification of the nonwoven fabric from different directions, and the second spray pipe's output direction is opposite to that of the main spray pipe, enhancing the humidification effect. Compared to traditional technologies, this multi-directional, adjustable humidification method ensures that all parts of the nonwoven fabric fully absorb moisture, resulting in a more uniform moisture content. This effectively avoids problems such as hardening and brittleness caused by uneven humidification, significantly improving the product quality of the nonwoven fabric and enabling it to better maintain its softness and flexibility during subsequent use.

[0014] 2. This tear-resistant nonwoven fabric humidification pretreatment device addresses the issue of traditional nonwoven fabric humidification processes, where the lack of effective tension control leads to stretching or deformation of the nonwoven fabric during humidification, thus reducing its tear resistance. Through a rational design and layout, this device achieves precise tension control of the nonwoven fabric. During humidification, the nonwoven fabric moves under the action of the in-wind and take-up rollers, with a servo motor driving the take-up roller to ensure stability during movement. Simultaneously, the various components work collaboratively to prevent excessive tension or pressure on the nonwoven fabric during humidification. Compared to traditional technologies, this precise tension control avoids deformation and damage to the nonwoven fabric during humidification, effectively enhancing its tear resistance, improving durability and reliability, and enabling it to better meet the needs of various complex application scenarios.

[0015] 3. This tear-resistant nonwoven fabric humidification pretreatment device addresses the problems of low humidification efficiency and high energy consumption associated with traditional nonwoven fabric humidification technologies, which not only increase production time but also raise production costs. This device significantly improves humidification efficiency and reduces production costs through optimized structure and workflow. The water pump in the device delivers water from the water tank to the spray pipes via a delivery hose and a second delivery hose, ensuring a timely supply of humidification water. Furthermore, the coordination of the bidirectional screw, adjusting rod, and second adjusting rod allows for rapid adjustment of the spray position, making humidification more precise and efficient. Compared to traditional technologies, this device reduces unnecessary humidification time and water waste, improving production efficiency. Simultaneously, due to uniform humidification and improved product quality, it reduces rework and scrap rates caused by product defects, further lowering production costs and enhancing the company's economic benefits and market competitiveness.

[0053] Working Principle: First, the nonwoven fabric is introduced through the infeed roller 21, undergoes a series of humidification processes, and is then wound up by the take-up roller 22. During the humidification process, the lateral movement mechanism of the device plays a crucial role. The fixed plate 2 is fixed to the top of the inner wall of the worktable 1, and its rack 5 meshes with the gear 7 inside the sliding plate 4. When the forward and reverse motor 6 starts, its rotating shaft drives the gear 7 to rotate. Due to the meshing relationship between the gear 7 and the rack 5, the sliding plate 4 moves laterally along the slide rail 3. This lateral movement allows the humidification component to be positioned along the length of the nonwoven fabric, providing a foundation for subsequent uniform humidification. Then, the components inside the adjustment box 8 work together to achieve precise control of humidification. The second forward and reverse motor 9 starts, driving the bidirectional lead screw 10 to rotate. The adjusting rod 11 and the second adjusting rod 12 on the bidirectional lead screw 10 are threadedly connected to the bidirectional lead screw 10 and move in opposite directions as the bidirectional lead screw 10 rotates. Spray pipes 13 and 14 are respectively provided on the outer walls of the opposite sides of the adjusting rod 11 and the second adjusting rod 12, with the second spray pipe 14 located directly below the spray pipe 13 and their output directions opposite. This structural design allows the distance and position between the spray pipes 13 and 14 to be flexibly adjusted when the adjusting rods 11 and 12 move, to accommodate non-woven fabrics of different widths and humidification requirements. The water tank 15 provides a water source for humidification, and the water pump 16 delivers water from the water tank 15 to the spray pipes 13 and 14 on the adjusting rods 11 and 12 respectively through the delivery hoses 17 and 18. As the adjusting rods 11 and 12 move, the spray pipes 13 and 14 can be adjusted above the non-woven fabric, while simultaneously spraying water evenly onto the surface of the non-woven fabric to achieve humidification. Finally, the humidified water drips into the water tank 19 at the bottom of the inner wall of the workbench 1 and is discharged through the drain hole 20, maintaining a clean working environment. The servo motor 23 drives the winding roller 22 to rotate, winding up the humidified nonwoven fabric.
