Description

Technical Field

[0001] The utility model relates to the field of non-woven fabric processing equipment, in particular to a non-woven fabric shaping device for facilitating the replacement of a hot rolling roll. Background Technique

[0002] Currently, when producing non-woven fabrics in factories, the production process can be divided into the following steps: spinning, air-cooling drawing, web laying, hot rolling, and winding. The non-woven fabric production line includes a monomer suction device, a web-forming machine, and a hot rolling machine. When hot rolling and heating and roll-pressing non-woven fabrics, it is usually achieved by heating with electric heating wires inside the hot rolling roll and performing roll-pressing heating through the hot rolling roll.

[0003] In existing hot rolling machines, the hot rolling rolls used for heating and roll-pressing are usually directly installed on the output shaft of the driving motor by welding. When it is necessary to replace the roll body in the later stage of use due to the deterioration of the flatness of the roll body surface, this installation method is not convenient for disassembling the hot rolling roll, which will directly reduce the product quality of roll-pressing hot rolling due to the influence on the contact surface between the non-woven fabric and the roll body surface after the flatness of the roll body surface deteriorates.

[0020] In this embodiment: by rotating the handle 13, the bidirectional threaded rod 7 rotates, enabling the two slide blocks 6 to move relatively and away from each other. The connecting seat 8 is arranged on the slide block 6. When the slide block 6 moves, it synchronously drives the connecting seat 8 to move. For the two guide card blocks 12 that are symmetric left and right, one of the guide card blocks 12 is arranged in the bearing 10 on the connecting seat 8 through a rotating shaft, and the other guide card block 12 is fixedly connected to the output end of the motor 9 through a rotating shaft. When the two connecting seats 8 move relatively, the guide card block 12 is clamped in the guide card slot 11 at both ends of the hot rolling roll 4, enabling the hot rolling roll 4 to be easily installed; by starting the motor 9, the hot rolling roll 4 can rotate, and the upper and lower two hot rolling rolls 4 rotate, which is easy to shape the non-woven fabric. When the hot rolling roll 4 needs to be replaced, rotate the handle 13 in the reverse direction, and the two slide blocks 6 drive the connecting seats 8 on both sides of the hot rolling roll 4 to move away from each other, and the guide card block 12 moves out of the guide card slot 11, making it easy to replace the hot rolling roll 4.
