[0020] like Figure 1-4As shown, a non-woven fabric hot rolling device proposed by the utility model includes a warehouse body 1 and a hot rolling mechanism 2, two limit frames are arranged on the left and right side walls of the warehouse body 1, the hot rolling mechanism 2 is arranged in multiple limit frames, and also includes a hot air generator 3, a hot air conveying component 4, multiple wind hoods 5, multiple rings 6 and a driving component 7. The hot air generator 3 is arranged at the top of the warehouse body 1, and the multiple wind hoods 5 are relatively arranged inside the warehouse body 1. The hot air conveying component 4 is arranged in the warehouse body 1 and connects the multiple wind hoods 5 and the hot air generator 3. The multiple rings 6 are respectively sleeved on the multiple wind hoods 5, and connecting rods 61 are arranged between the multiple rings 6. The driving component 7 is arranged in the warehouse body 1 and drives the multiple rings 6 to rotate.

[0021] In the utility model, the limiting frames are grouped in pairs, with a total of two groups, the upper and lower groups. The hot rolling mechanism 2 includes a driving motor, a transmission belt, an electric telescopic rod, a hot pressing roller and a shock-absorbing telescopic rod, etc., which are used to transport different non-woven fabrics while hot rolling them, and then perform shock absorption during hot rolling to ensure stability. Before hot rolling, hot air is generated by using a hot air generator 3, and is transported to each wind hood 5 through a hot air conveying component 4, and then hot air is emitted to preheat the upper and lower surfaces of the non-woven fabric. Each wind hood 5 is provided with a ring 6, and the rings 6 are connected by a connecting rod 61. The ring 6 is rotated by using a driving component 7, so that the wind hood 5 is turned or swung. Different non-woven fabrics require different distances between the wind hood 5 and the non-woven fabric when hot air is preheated. By rotating the direction of the wind hood 5, the distance between the hot air blown out by the wind hood 5 and the non-woven fabric is increased, so that the non-woven fabric can be better heated.

[0022] In an optional embodiment, a feed port is opened on the right side of the bin body 1, and a plurality of wind hoods 5 are respectively located on the upper and lower sides of the feed port.

[0023] It should be noted that the plurality of wind hoods 5 are located inside the bin body 1 and at the left side of the feed inlet. As soon as the nonwoven fabric enters the bin body 1, it can be preheated by hot air.

[0024] In an optional embodiment, the hot air delivery assembly 4 includes a shunt pipe 41, two air outlet pipes 42 and multiple hot air hoses 43. The input end of the shunt pipe is connected to the delivery end of the hot air generator 3. The two air outlet pipes 42 are respectively arranged on opposite sides of the two right limit frames and are connected to the two output ends of the shunt pipe 41. The hot air hoses 43 are respectively connected between the two air outlet pipes 42 and multiple wind hoods 5.

[0025] It should be noted that the shunt pipe 41 has two output ends, the input end of the shunt pipe 41 is connected to the output end of the hot air generator 3, the hot air generated by the hot air generator 3 is blown into the shunt pipe 41, flows from the two output ends of the shunt pipe 41 to the two air outlet pipes 42, then flows to the multiple hot air hoses 43, and then blown out from the wind hood 5. Due to the characteristics of the hot air hose 43, the hot air can still be transported when the ring 6 drives the wind hood 5 to rotate.

[0026] In an optional embodiment, a fixing frame 8 is provided on the rear side of the bin body 1, and the fixing frame 8 is L-shaped.

[0027] In an optional embodiment, the driving assembly 7 includes a motor 71, a worm gear reducer 72, two first rotating rods 73, two second rotating rods 74, and two gears 75. The worm gear reducer 72 is arranged on a fixed frame, the motor 71 is arranged on the worm gear reducer 72, and the output shaft is coaxially connected with its input end, one end of the two first rotating rods 73 is respectively connected to the left sides of the two left rings 6, one end of the two second rotating rods 74 is respectively connected to the right sides of the two right rings 6, the other end of the upper second rotating rod 74 extends to the rear side of the warehouse body 1, and the other end of the lower second rotating rod 74 is coaxially connected to the output end of the worm gear reducer 72, and the two gears 75 are coaxially sleeved on the two second rotating rods 74, and the two are meshed with each other.

[0028] It should be noted that the working principle of the worm gear reducer 72 is based on the mutual meshing of the worm and the worm wheel. When the motor 71 drives the worm to rotate, the spiral tooth surface on the worm will push the tooth surface of the worm wheel, so that the worm wheel rotates, and the rotation of the worm will drive the lower second rotating rod 74 to rotate, and the upper second rotating rod 74 and the lower second rotating rod 74 can be rotated in opposite directions through two meshing gears 75, so that when adjusting the direction of multiple wind hoods 5, the wind hoods 5 on the upper and lower sides can face the same direction.

[0029] In an optional embodiment, a discharge port is provided on the left side of the warehouse body 1 , and heat dissipation windows 9 are provided on both the left and right sides of the warehouse body 1 .

[0030] It should be noted that the heat dissipation window 9 is used to dissipate heat inside the warehouse body 1 .

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
