Description

Technical Field

[0001] The utility model belongs to the field of non-woven fabric shaping equipment and relates to a non-woven fabric shaping machine. Background Art

[0002] Non-woven fabrics are made of polyester fiber through a needle-punching process. During the production process, non-woven fabrics need to be shaped to make them more beautiful and smoother. Heat setting is one of the most commonly used non-woven fabric shaping methods. The non-woven fabric is heated by hot air, hot rollers or hot pressing, so that it can be deformed and keep the desired shape during the cooling process. This method can not only improve the surface smoothness of the non-woven fabric, but also enhance its hardness and waterproof performance.

[0003] The patent document with publication number CN212714123U discloses a non-woven fabric shaping structure, wherein the initial non-woven fabric is passed through a cloth-releasing roller and sequentially heated by a heating mechanism, pressed by a shaping mechanism to form a non-woven fabric product, and then wound on a cloth-collecting roller after the heat is dissipated by a heat dissipation mechanism.

[0004] However, the above-mentioned prior art still has the following deficiencies: in the prior art, the non-woven fabric is heated by a heating mechanism to soften the non-woven fabric, and then the non-woven fabric is shaped between two shaping rollers. However, since the non-woven fabric softens after heating, it is relatively loose, and the non-woven fabric is not stretched and tensioned during rolling and shaping. The non-woven fabric will partially wrinkle after relaxation, resulting in secondary rolling and aggravating the overlapping of wrinkles during shaping, affecting product quality. At the same time, some substances on the heated non-woven fabric will melt and become more viscous. The contact area between the relaxed non-woven fabric and the shaping roller will increase, resulting in more viscous substances easily adhering to the shaping roller, thereby affecting the subsequent shaping effect. Utility Model Content

[0005] The utility model aims to solve the deficiencies of the prior art and proposes a non-woven fabric shaping machine to solve the technical problems mentioned in the background technology that the non-woven fabric in the prior art is easily softened after heating, causing it to relax and resulting in poor shaping effect, and the contact area between the relaxed non-woven fabric and the shaping roller is increased, causing more viscous substances to easily adhere to the shaping roller, further resulting in poor shaping effect.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A non-woven fabric shaping machine comprises a shaping frame, in which two symmetrically arranged tensioning frames are slidably provided, a lifting mechanism is provided on the top of the shaping frame, two pull ropes are respectively wound and fixed at both ends of the lifting mechanism, the winding directions of the pull ropes at both ends of the lifting mechanism are opposite, the pull ropes at both ends of the lifting mechanism are respectively fixedly connected to the upper ends of the two tensioning frames, the lifting mechanism is used for simultaneously winding and unwinding the pull ropes at both ends to drive the two tensioning frames to rise and fall respectively, a shaping frame is rotatably provided in the tensioning frame, two symmetrically arranged shaping rollers are rotatably installed in the shaping frame, and an adjusting component for driving the shaping frame to rotate is provided on one side of the tensioning frame.

[0008] Working principle:

[0009] The non-woven fabric that has been softened and relaxed after heating treatment passes between the front and rear tensioning frames, and then passes between the two shaping rollers. The lifting mechanism is driven to simultaneously reel in and unreel the ropes at both ends, so that the two tensioning frames rise and fall respectively, so that the non-woven fabric is stretched, and the tension of the non-woven fabric is quickly adjusted to avoid poor shaping effect due to relaxation. At the same time, the shaping frame is driven to rotate through the adjusting component, and the shaping frame drives the two shaping rollers to rotate synchronously, thereby adjusting the inclination of the two shaping rollers to reduce the contact area between the non-woven fabric and the pressure roller, thereby reducing the adhesion of hot-melt substances on the surface of the heated non-woven fabric to the shaping roller, and further improving the shaping quality.

[0010] The beneficial effects of the utility model are:

[0011] The utility model provides two tensioning frames and a lifting mechanism, and drives the lifting mechanism to simultaneously reel in and unreel the pull ropes at both ends, thereby achieving the two tensioning frames to rise and fall along the slide groove respectively, so that the non-woven fabric is stretched, and the tension of the non-woven fabric is quickly adjusted, thereby improving the shaping effect of the non-woven fabric;

[0012] The utility model provides an adjusting component and a shaping frame, and the adjusting component drives the shaping frame to rotate, and the shaping frame drives two shaping rollers to rotate synchronously, so as to adjust the inclination of the two shaping rollers to reduce the contact area between the non-woven fabric and the shaping roller, thereby reducing the adhesion of hot-melt materials on the surface of the heated non-woven fabric to the shaping roller, further improving the shaping effect of the non-woven fabric, and prolonging the service life of the shaping roller.
