DETAILED DESCRIPTION

[0018] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] like Figures 1 to 6 As shown, the utility model provides: a multi-roll composite calendering device for SMS non-woven fabric, comprising a base 1, a rotatable feed roller 2 and a discharge roller 5 are arranged on the top of the base 1, a frame 4 is arranged on the top of the base 1, a spring telescopic rod 11 is arranged inside the frame 4, and a mounting frame 10 is arranged at the telescopic end of the spring telescopic rod 11, a calendering roller 9 for calendering the non-woven fabric is rotatably arranged inside the mounting frame 10, heating rollers 8 for heating the non-woven fabric are also rotatably arranged on both sides of the interior of the frame 4, a heating rod 12 is arranged inside the heating roller 8, and a plurality of exhaust holes for exhausting air are provided on the outer wall of the heating roller 8, a rectangular groove is provided on the top of the base 1, moving blocks 7 are movably arranged on both sides of the interior of the rectangular groove, a guide roller 3 for guiding the non-woven fabric is rotatably arranged on the top of the moving block 7, a guide rod 17 is movably arranged between the two moving blocks 7, and the two ends of the guide rod 17 are respectively connected to the inner walls of the two sides of the rectangular groove.

[0020] The non-woven fabric can be calendered by the calendering roller 9, and the spring telescopic rod 11 cooperates with the mounting frame 10 to calender non-woven fabrics of different thicknesses. When the non-woven fabric needs to be continuously heated, the feed roller 2 can be rotated back and forth so that the non-woven fabric is always moving on the surface of the heating roller 8, and the non-woven fabric can also be kept in a heated state.

[0021] The heating rod 12 inside the heating roller 8 can continuously heat the non-woven fabric. This ensures that the non-woven fabric can obtain a uniform and stable temperature throughout the entire production process. At the same time, in order to ensure the optimization of the heating effect, a plurality of exhaust holes are opened on the outer wall of the heating roller 8. The exhaust holes allow the hot air generated inside the heating roller 8 to be discharged smoothly, avoiding heat accumulation caused by excessive internal pressure. The non-woven fabric on the surface of the heating roller 8 can be heated uniformly and effectively, thereby ensuring the quality and production efficiency of the non-woven fabric.

[0022] The guide roller 3 can effectively guide the running path of the non-woven fabric. In this way, the non-woven fabric can remain flat when passing through the heating device, avoiding wrinkles caused by uneven heating or improper operation. The precise guiding effect of the guide roller 3 ensures the quality stability of the non-woven fabric during the production process, thereby improving the overall quality of the final product.

[0023] By using the guide rod 17, it is possible to ensure that the moving block 7 and the guide roller 3 maintain a high degree of stability during the movement, thereby avoiding any positional deviation. The guide rod 17 enables the moving block 7 and the guide roller 3 to move smoothly along a predetermined trajectory, ensuring that they do not deviate from the predetermined position during the movement.

[0024] like Figure 5 and Figure 6 As shown, a motor 6 is provided at the front end of the base 1, and a rotating rod 13 is provided on the output shaft of the motor 6 through a coupling. One end of the rotating rod 13 extends to the inside of the rectangular groove and is rotatably connected to the inner wall of the rectangular groove. A gear 16 is provided on the outside of the rotating rod 13, and racks 14 meshing with the gear 16 are provided on the opposite sides of the two moving blocks 7.

[0025] The motor 6 drives the rotating rod 13 to rotate, and at the same time, the gear 16 outside the rotating rod 13 also rotates, further cooperating with the rack 14 on the side wall of the moving block 7, thereby driving the two moving blocks 7 to move closer to or away from each other, thereby facilitating the adjustment of the angle of the non-woven fabric when heated, so that the non-woven fabric is heated more evenly.

[0026] like Figure 5 and Figure 6 As shown, a limiting block 15 is arranged on one side of the rack 14, and a limiting groove for the limiting block 15 to move is opened on the inner wall of the rectangular groove.

[0027] The limiting block 15 slides inside the limiting groove, ensuring that the rack 14 can be more stable when working with the gear 16, thereby avoiding the possible tooth stripping phenomenon. The rack 14 can maintain accurate cooperation with the gear 16 during the movement.

[0028] Working principle: During the calendering process of non-woven fabrics, one end of the non-woven fabric needs to be passed through the feed roller 2 and the guide roller 3 respectively to ensure that the non-woven fabric can enter the calendering equipment smoothly. Then, the non-woven fabric is placed on top of the two heating rollers 8 for the next step of heating and calendering. Subsequently, the non-woven fabric needs to be placed on top of the discharge roller 5 to complete the entire calendering process. When the non-woven fabric is placed on top of the two heating rollers 8, the operator can use the calendering roller 9 to perform a detailed calendering process on the non-woven fabric to achieve the required smoothness and texture. In order to adapt to non-woven fabrics of different thicknesses, a spring telescopic rod 11 and a mounting frame 10 are used. Through the cooperation of the two, the pressure of the calendering roller 9 can be flexibly adjusted to ensure that a uniform calendering effect can be obtained regardless of how the thickness of the non-woven fabric changes. During the calendering process, if the non-woven fabric needs to be continuously heated, it can be achieved by rotating the feed roller 2 back and forth. The non-woven fabric can be continuously moved on the surface of the heating roller 8, thereby keeping the non-woven fabric in a heated state and ensuring uniform heating. In addition, in order to adjust the angle of the non-woven fabric when heated to achieve a more uniform heating effect, the device is also designed with an adjustable guide roller 3. When the distance between the two guide rollers 3 needs to be adjusted, the operator can start the motor 6, and the motor 6 drives the rotating rod 13 to rotate. The gear 16 outside the rotating rod 13 will also rotate accordingly, and further cooperate with the rack 14 on the side wall of the moving block 7. In this way, the moving blocks 7 can be moved closer to or away from each other, so as to conveniently adjust the angle of the non-woven fabric when heated, ensure that the non-woven fabric can receive heat more evenly during the heating process, and improve the uniformity and quality of the calendering effect.
