Description

Technical Field

[0001] This utility model relates to the technical field of twin-roll hot rolling mills, specifically to a twin-roll hot rolling mill for nonwoven fabrics. Background Technology

[0002] Hot rolling mill is a type of equipment used for rolling materials during processing and production. Hot rolling is used in production due to its advantages such as low energy consumption. The use of hot rolling in the production of non-woven fabrics makes them durable.

[0003] In existing technologies, such as the "A Nonwoven Fabric Double Roller Hot Rolling Mill" with Chinese Patent No. CN213896223U, when the processed nonwoven fabric moves in the box through the guide rollers, the squeezing action of the extrusion rollers on the hose causes the hose to send the cold air from the refrigeration equipment out of the empty pipe, so that the cold air enters the empty pipe through the through pipe and is blown towards the nonwoven fabric under the action of the air outlet, so that the nonwoven fabric is rapidly cooled down under the action of the cold air.

[0004] The hot rolling rolls on the hot rolling mill generate a lot of heat during use. However, in the existing technology mentioned above, the hot rolling mill cannot further utilize this heat and does not preheat the nonwoven fabric. This easily leads to poor heating effect after entering the equipment, and all the heat is discharged to the outside, resulting in a large amount of heat loss.

[0005] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content

[0035] The cleaning component 4 includes a pair of rotating rollers 4-1, both of which are rotatably connected inside the equipment housing 1. Each of the rotating rollers 4-1 has a transmission gear 4-2 at one end. A drive motor 4-3 is provided on the side surface of the equipment housing 1. The output end of the drive motor 4-3 is connected to one of the rotating rollers 4-1. A cavity 4-4 is provided inside the rotating roller 4-1. Several cleaning layers 4-5 are provided on the surface of the rotating roller 4-1. Several air holes 4-6 are provided on the surface of the rotating roller 4-1.

The rotating sleeves 4-8 are rotatably connected to one end of the rotating roller 4-1. The connecting pipe 4-7 is connected to the cavity 4-4.

[0036] In this embodiment, a cleaning component 4 is designed to achieve the effect of cleaning the surface of the non-woven fabric. Two rotating rollers 4-1 are rotatably connected inside the equipment housing 1, and a transmission gear 4-2 is provided at one end. A drive motor 4-3 is also provided on the outside of the equipment housing 1. The output end of the drive motor 4-3 is connected to one of the rotating rollers 4-1, which can start the two rotating rollers 4-1 to rotate synchronously. The surface of the rotating roller 4-1 is provided with a cleaning layer 4-5, which can clean both sides of the non-woven fabric when rotating. The rotating roller 4-1 has a cavity 4-4 and multiple air holes 4-6. The suction end of the vacuum blower 3 is provided with a connecting pipe 4-7 and a rotating sleeve 4-8. The rotating sleeve 4-8 is rotatably connected to one end of the rotating roller 4-1. By communicating with the vacuum blower 3, the air holes 4-6 can generate suction to absorb the foreign objects swept off.

[0037] Furthermore, the hot-rolled return air assembly 5 includes a pair of hot-rolled rolls 5-1, both of which are installed inside the equipment housing 1. A pair of bonding rolls 5-2 are rotatably connected inside the equipment housing 1, with the bonding rolls 5-2 located on both sides of the upper hot-rolled rolls 5-1. A pair of air hoods 5-3 are provided inside the equipment housing 1, with heat collection holes 5-4 opened on the surface of the air hoods 5-3. A centralized pipe 5-5 is provided on the outer surface of the equipment housing 1, with both ends of the centralized pipe 5-5 connected to the air hoods 5-3. A ventilation fan 5-6 is provided on the outer surface of the equipment housing 1, with the air inlet of the ventilation fan 5-6 connected to the centralized pipe 5-5. A pair of return air pipes 5-7 are provided inside the equipment housing 1, with the return air pipes 5-7 connected to the output end of the ventilation fan 5-6. Several horizontal holes 5-8 are opened on the surface of the return air pipes 5-7.

[0038] In this embodiment, to achieve the effect of preheating using the heat of the hot rolling rollers 5-1, a hot rolling return air assembly 5 is designed. Two hot rolling rollers 5-1 are rotatably connected inside the equipment housing 1 for hot rolling the nonwoven fabric. Two bonding rollers 5-2 are also rotatably connected to lift the nonwoven fabric, increasing the bonding area between the nonwoven fabric and the surface of the hot rolling rollers 5-1, thus providing a better hot rolling effect. Two air hoods 5-3 are provided inside the equipment housing 1. The inner surface of the air hoods 5-3 has heat collection holes 5-4. An external ventilation fan 5-6 and a centralized pipe 5-5 are provided. With the ventilation fan 5-6, heat can be drawn from the surface of the hot rolling rollers 5-1. Two return air pipes 5-7 are provided inside the equipment housing 1, and multiple horizontal holes 5-8 are opened on the surface. The drawn hot air can be blown onto the cleaned nonwoven fabric surface through the horizontal holes 5-8 on the surface of the return air pipes 5-7 to achieve the preheating effect.

[0041] Furthermore, the air hood 5-3 has an arc-shaped transition structure, and the curvature of the air hood 5-3 matches the surface curvature of the hot rolling roll 5-1.

[0042] In this embodiment, the arc-shaped transition structure allows the air hood 5-3 to be closer to the hot rolling roll 5-1, improving the utilization of excess heat.

[0043] Furthermore, the surface of the return gas pipe 5-7 located at the transverse hole 5-8 is an inclined structural surface.

[0044] In this embodiment, by tilting the structural surface, the hot air blown out of the horizontal holes 5-8 can cover a large area of ​​the nonwoven fabric surface, thereby improving the preheating effect.

[0045] When hot rolling is required, the nonwoven fabric enters from one end of the rotating roller 4-1, passes through the conveying roller 2, and enters the equipment housing 1. After passing over the bonding roller 5-2 and the two hot rolling rollers 5-1 at the top, it is conveyed outward. During the hot rolling process, the rotating roller 4-1 is started to clean the surface of the nonwoven fabric through the cleaning layer 4-5, and the dust extraction fan 3 is kept running while the air hole 4-6 draws in foreign objects. During the hot rolling process, the heat collection hole 5-4 absorbs the heat from the surface of the hot rolling roller 5-1 and blows it out through the horizontal hole 5-8 of the return air duct, directly covering the surface of the nonwoven fabric. After reaching the preheated state, hot rolling can be carried out.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
