[0004] In summary, the non-woven fabric winding device has the disadvantages of complicated winding operation and difficulty in taking out the fabric as needed. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of the prior art non-woven fabric winding device, which has the disadvantages of complicated winding operation and difficulty in taking out the fabric as needed. It provides a winding device for preparing non-woven fabric that is convenient for winding, compacting and taking out as needed.

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

[0007] A winding device for preparing non-woven fabrics includes a bracket and a rotating rod, the rotating rod is rotatably connected to the bracket, the bracket is provided with a pressing assembly and a cutting assembly, the pressing assembly is elastically connected to the bracket, the cutting assembly is movably connected to the bracket through the pressing assembly, the cutting assembly includes a positioning plate, a guide seat and a cutter structure, the guide seat is connected to the pressing assembly, the positioning plate is detachably connected to the guide seat, the positioning plate is provided with a cloth threading opening, one end of the cutter structure is slidably connected to the guide seat, and the other end of the cutter structure is movably connected to the positioning plate.

[0008] The rotating rod is connected to the bracket to roll up the non-woven fabric. The bracket is equipped with a pressing assembly and a cutting assembly. The cutting assembly can move up and down in the bracket through the pressing assembly to adapt to the thickness change of the roll. The cutting assembly presses the non-woven fabric below under the elastic force of the pressing assembly, so that the non-woven fabric roll is tightened during the roll-up. The guide seat in the cutting assembly is connected to the pressing assembly so that the pressing assembly can press the guide seat to move. The positioning plate allows the tail end of the non-woven fabric roll to pass through the cloth-threading opening for tightening and fixing. The cutter structure is slidably connected on the guide seat and then cuts the non-woven fabric roll on the positioning plate by movement. The positioning plate provides cutting support and positioning for the cutter and non-woven fabric, so that the non-woven fabric can be cut quickly and stably to any length. This achieves the effect of convenient rolling and pressing of the non-woven fabric and quick and on-demand cutting of the cloth.

[0009] Preferably, the cutter structure includes a slider and a cutter. The guide seat is provided with a guide slot, which is provided with a positioning hole. The slider is slidably connected to the guide slot, the cutter is connected to the slider, and the cutter is slidably connected to the positioning hole. The slider in the cutter structure reciprocates within the guide slot within the guide seat to limit and guide the cutter connected to the slider. The cutter is positioned and guided by the positioning hole, thereby improving the stability and efficiency of the cutting operation.

[0010] Preferably, the guide chute has a limiting groove in its wall, the slider is connected to a limiting block, and the limiting block is slidably connected to the limiting groove. The limiting groove in the guide chute allows the limiting block connected to the slider to slide within the limiting groove, preventing the slider from falling out of the guide chute. This further improves operational stability.

[0011] Preferably, the guide base is provided with a connecting block, one end of which is connected to the guide base, and the other end of which is provided with a positioning slot, into which the positioning plate is inserted. The slot wall of the positioning slot is provided with a socket, into which a limit plate is inserted. The connecting block is connected to the guide base, so that the positioning plate can be positioned, installed, and removed through the positioning slot, allowing for quick insertion through the non-woven fabric during removal. The socket in the positioning slot is connected to the limit plate, further facilitating the positioning and securing of the positioning plate. This improves the structural connection accuracy and stability, and enhances operational convenience.

[0012] Preferably, the positioning plate is provided with a limiting groove, the cutter is slidably connected to the limiting groove, the cloth threading opening includes a cloth inlet and a cloth outlet, the cloth inlet and the cloth outlet are symmetrically arranged with the limiting groove as the center, the connecting block is provided with a clearance hole, and the clearance hole is connected to the limiting groove. The surface of the positioning plate is provided with a limiting groove, the limiting groove has a cloth inlet on one side and a cloth outlet on the other side, so that the non-woven fabric enters from one side through the limiting groove and exits from the other side, so as to increase the tension when winding and provide guidance when pulling out. The limiting groove leaves space above and below the non-woven fabric, making it easier for the cutter to cut the non-woven fabric when passing through. The cutter is isolated on the other side of the positioning plate by the connecting block to make the cutter safer to use. The cutter passes through the clearance hole and enters the limiting groove during sliding. This improves the efficiency and stability of the cutting operation and improves the safety of use.

[0013] Preferably, the bracket is provided with a guide slide hole, and the clamping assembly includes a support block, a guide rod and an elastic mechanism. The guide seat is plugged into the guide slide hole, and the guide seat is provided with a guide hole. One end of the guide rod is connected to the support block, and the other end of the guide rod is plugged into the guide hole. The elastic mechanism is sleeved with the guide rod, and one end of the elastic mechanism is connected to the guide seat, and the other end of the elastic mechanism is connected to the support block. The support block in the clamping assembly is connected to the bracket to support the guide seat connected above by the elastic mechanism. The guide seat extends through the guide slide hole and is connected to the elastic mechanism, thereby improving the stability of movement on the bracket. The support block is vertically connected to the guide rod, so that the guide seat can move up and down on the guide rod with further stability by plugging into the guide rod. The elastic mechanism provides a pressing force between the positioning plate and the non-woven fabric when winding and automatically increases with the thickness. This achieves the effect of improving structural connection and operational stability.

[0014] The beneficial effects of the utility model are: realizing convenient and compact rolling of non-woven fabric; fast and on-demand cutting of fabric; improving the accuracy and stability of structural connection; improving the stability and efficiency of cutting operation; and improving the safety of use.
