Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabrics, in particular to a non-woven fabric hot rolling machine. Background Art

[0002] The non-woven fabric hot rolling mill is a key equipment in the textile industry. It is used to process non-woven fabric raw materials into denser and stronger fabrics through high temperature and pressure. It can improve the wear resistance, stretchability and breathability of non-woven fabrics. It is widely used in clothing, medical care, home furnishings and construction. The machine has a high degree of automation and can stably and reliably produce a variety of non-woven fabric products to meet various market needs.

[0003] The utility model with the authorization publication number CN220132575U provides a double-roll hot rolling mill for non-woven fabrics, which belongs to the technical field of "non-woven fabrics". The protected claim: "It includes a bottom plate, and the top of the bottom plate is fixedly installed with a first support rod, a second support rod and a fourth support rod, the top of the first support rod is provided with a feed roller, the top of the second support rod is provided with a hot rolling roller, the top of the fourth support rod is provided with a receiving roller, and a first motor is fixedly installed on one side of the top of the fourth support rod. The output end of the first motor is fixedly connected to the receiving roller, and a waste heat collection mechanism is provided on the top of the bottom plate. The high temperature emitted by the non-woven fabric after processing by the hot rolling roller is collected by the waste heat collection mechanism, and the waste heat is used to preheat the non-woven fabric through the preheating mechanism to increase the effect of hot rolling of the non-woven fabric, and the processed non-woven fabric is cooled in cooperation with the cooling mechanism. This can facilitate the winding operation of the receiving roller, avoid the non-woven fabric from bonding due to high temperature, and improve the processing quality of the non-woven fabric."

[0004] In this equipment, although the non-woven fabric can be cooled, the non-woven fabric needs to maintain a certain tension during the hot rolling and cooling process to prevent it from loosening or deforming under heating and cooling conditions. Adjusting the tension helps to maintain the flatness and stability of the non-woven fabric, thereby ensuring the consistency of the rolling effect. For this reason, we propose a non-woven fabric hot rolling machine. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-4 As shown, in this embodiment, a non-woven fabric hot rolling mill includes a base plate 100, a hydraulic rod 120, a rotating rod 150 and a slide rail 180, and a box body 110 is fixedly connected to the base plate 100; two hydraulic rods 120 are fixedly connected to the top of the box body 110, and the driving ends of the two hydraulic rods 120 pass through the top of the box body 110 and are fixedly connected to the first connecting shaft 130, and the first roller body 140 is rotatably connected between the two first connecting shafts 130; the two rotating rods 150 are rotatably connected to the outside of the first connecting shaft 130, and the bottom ends of the two rotating rods 150 are rotatably connected to the second connecting shaft 160, and one end of the two second connecting shafts 160 is rotatably connected to the second roller body 170; the two slide rails 180 are fixedly connected to the inner side of the box body 110, and the other ends of the two second connecting shafts 160 are slidably connected in the slide rail 180.

[0023] In the specific implementation, the non-woven fabric passes through the hot rolling box 500, passes through the guide roller 310, the first roller body 140 and the second roller body 170 in the box body 110 in sequence, and then passes through the pressing roller 600. Then, it is moved and wound by the feeding roller 400 and the receiving roller 700. The non-woven fabric is heated and pressed by the hot rolling box 500, and then enters the box body 110 and is cooled by the fan 200. Finally, it is rolled after the second pressing of the pressing roller 600. The non-woven fabric will relax or deform under the conditions of heating and cooling. At this time, the two hydraulic rods 120 are started, and the two The hydraulic rod 120 drives the two first connecting shafts 130 and the first roller body 140 to move upward, thereby driving the two sets of rotating rods 150 to rotate inward, and synchronously driving the two sets of second connecting shafts 160 and the two second roller bodies 170 to move inward along the slide rail 180. In this way, the two sections of non-woven fabric located on both sides of the box body 110 will be tightened inward, and vice versa, the non-woven fabric can be relaxed. In summary, the device can adjust the tension to prevent it from relaxing or deforming under heating and cooling conditions, which helps to maintain the flatness and stability of the non-woven fabric, thereby ensuring the consistency of the rolling effect.

[0024] Furthermore, the two sets of slide rails 180 are respectively tilted relative to each other, and positioning bolts 181 are threadedly inserted in the two sets of slide rails 180. By setting the positioning bolts 181 and changing the position of the positioning bolts 181 in the slide rails 180, the tightening degree can be adjusted.

[0025] Furthermore, a fan 200 is fixedly provided on the top of the box body 110. The fan 200 can be connected to an external air duct to cool the device and bring the internal heat out of the device.

[0026] Furthermore, slots 300 are provided on both sides of the box body 110 , and two guide rollers 310 are rotatably connected in the two slots 300 . The guide rollers 310 are used to guide the non-woven fabric into the box body 110 .

[0027] Furthermore, a feed roller 400 and a hot rolling box 500 are provided on one side of the box body 110. The feed roller 400 and the hot rolling box 500 are both fixedly mounted on the bottom plate 100. By setting the feed roller 400, the non-woven fabric can be fed, and by setting the hot rolling box 500, the non-woven fabric can be heated and rolled. A hot rolling machine is provided in the hot rolling box 500. The hot rolling machine is an existing technology and will not be described in detail.

[0028] Furthermore, a pressing roller 600 and a receiving roller 700 are provided on the other side of the box body 110. The pressing roller 600 and the receiving roller 700 are both fixedly mounted on the bottom plate 100. By providing the pressing roller 600, the non-woven fabric can be pressed for a second time. Through the secondary pressing, the fibers inside the non-woven fabric can be more tightly combined together, thereby improving its density. This increase in density helps to improve the strength and durability of the non-woven fabric. By providing the receiving roller 700, the non-woven fabric can be wound up.

[0029] Working principle: First, the non-woven fabric passes through the hot rolling box 500, and then passes through the guide roller 310, the first roller body 140 and the second roller body 170 in the box body 110 in sequence, and then passes through the pressing roller 600, and then passes through the feeding roller 400 and the receiving roller 700 for winding and moving. The non-woven fabric passes through the hot rolling box 500 for heating and pressing, and then enters the box body 110 for cooling through the fan 200, and finally passes through the secondary pressing of the pressing roller 600 for winding. The non-woven fabric will relax or deform under the conditions of heating and cooling. At this time, the two hydraulic rods 120 are started, and the two hydraulic rods 120 are pressed. A hydraulic rod 120 drives the two first connecting shafts 130 and the first roller body 140 to move upward, thereby driving the two sets of rotating rods 150 to rotate inward, and synchronously driving the two sets of second connecting shafts 160 and the two second roller bodies 170 to move inward along the slide rail 180. In this way, the two sections of non-woven fabric on both sides of the box body 110 will be tightened inward, and vice versa, the non-woven fabric can be relaxed. In summary, the device can adjust the tension to prevent it from relaxing or deforming under heating and cooling conditions, which helps to maintain the flatness and stability of the non-woven fabric, thereby ensuring the consistency of the rolling effect.
