Description

Technical Field

[0001] The utility model relates to the technical field of non-woven cotton layer exhaust, in particular to a non-woven cotton layer exhaust roller. Background Art

[0002] Non-woven fabrics need to be degassed during the production process to ensure product quality and performance. The main purpose of degassing is to remove bubbles from non-woven fabrics to make them tighter and smoother. The methods of degassing non-woven fabrics usually include the following: 1. Hot pressing degassing: The non-woven fabric is contacted with a hot roller or hot plate through a hot pressing process, and the bubbles are expelled by thermal pressure, while making the surface of the non-woven fabric smoother. 2. Vacuum degassing: The non-woven fabric is placed in a vacuum chamber using vacuum equipment, and the bubbles are expelled by negative pressure. This is suitable for situations where the surface requirements of non-woven fabrics are high. 3. Degassing roller: A specially designed degassing roller is used to roll and degas the non-woven fabric on the production line to effectively remove bubbles and improve product quality. 4. Airflow degassing: The non-woven fabric is degassed through airflow to allow bubbles to be discharged smoothly. This is suitable for non-woven fabrics of special shapes or materials. The above methods can select the appropriate degassing method according to different production requirements and equipment conditions to ensure that the non-woven fabrics meet the ideal quality standards during the production process.

[0003] A non-woven cotton layer exhaust roller and non-woven fabric production equipment disclosed in the Chinese utility model patent application disclosure specification CN216473799U, although the utility model adopts seamless steel pipes and roller shafts to improve the coaxiality of the roller and avoid eccentric rotation, and the roller body is formed by winding the seamless steel pipe instead of the traditional steel plate, which reduces the processing difficulty, improves production efficiency, and improves the cylindricity and rigidity of the roller surface, but it is not convenient to adjust the height of the exhaust roller, and thus cannot quickly adapt to non-woven fabrics of different thicknesses, has the disadvantage of poor convenience, and has the disadvantage of poor exhaust effect during the exhaust process.

[0013] (III) Beneficial effects

[0014] The utility model provides a non-woven cotton layer exhaust roller, which has the following beneficial effects:

[0015] 1. The non-woven cotton layer exhaust roller has the effect of conveniently adjusting the height of the exhaust roller through the arrangement of the first lifting block, the first threaded rod, the active gear, the hinge, the second lifting block, the second threaded rod and the driven gear. When in use, the device is installed on both sides of the conveyor belt for non-woven fabric production, and the non-woven cotton layer passes under the exhaust roller body. In the process of exhausting the non-woven cotton layer, the staff sets the roller pressure height adapted to the exhaust roller body according to the thickness of the non-woven cotton layer on the conveyor belt. When adjusting the height of the exhaust roller body, the staff turns the crank to drive the first threaded rod and the active gear to rotate through the crank, so that the first threaded rod moves on the upper surface of the first through groove through the first threaded rod. The first lifting block is driven to slide in the first through groove. During the sliding process of the first lifting block, the limiting sliding block on the side of the first lifting block slides in the limiting sliding groove, which plays a limiting role, thereby changing the position of the first lifting block. At the same time, the active gear drives the driven gear through the hinge to make the second threaded rod move the upper surface thread of the second mounting block. Similarly, the second lifting block is driven to slide in the second through groove. Since the threads of the first threaded rod and the second threaded rod are opposite, the first lifting block and the second lifting block are lifted and lowered synchronously, driving the motor, the rotating rod and the exhaust roller body to move together. By turning the crank, the rolling height of the exhaust roller body is quickly changed, which is suitable for the exhaust of non-woven fabrics of different thicknesses and achieves the purpose of improving the convenience of use.

[0016] 2. The non-woven cotton layer exhaust roller has the effect of improving the exhaust effect through the setting of the rotating block, the rotating frame and the pressing block. When in use, when the non-woven cotton layer passes under the exhaust roller body, the rotating frame and the pressing block rotate on the surface of the rotating rod under the action of gravity, and the lower surface of the pressing block is pressed on the upper surface of the non-woven cotton layer. The higher part of the surface of the non-woven cotton layer is pressed down by the gravity of the pressing block, so that the non-woven cotton layer can pass smoothly under the exhaust roller body, avoiding the non-woven cotton layer from being entangled on the exhaust roller body due to being too high, thereby achieving the purpose of improving the exhaust effect.
