[0002] Imitation leather-textured nonwoven fabric is a product of further impregnation and processing on high-density needle-punched nonwoven fabric. It has the texture of imitation leather, is soft and fleshy, and has a significantly higher density than regular nonwoven fabric; it is widely used in furniture production. During the production process, imitation leather-textured nonwoven fabric needs to be cut according to product specifications, separating wide strips into narrow strips.

[0003] CN119953946A discloses a winding and slitting device for nonwoven fabric production, which offers flexible applicability to production control of slitting methods and specifications; provides neat and stable slitting; improves the efficiency of nonwoven fabric winding and unwinding; enhances structural operational stability and tangential accuracy; and is simple and quick to operate, enabling rapid control of slitting specifications. However, during the slitting and winding process, the nonwoven fabric and its roll are not properly held. Because the imitation leather-textured nonwoven fabric is more supple and elastic, it is prone to springback during the slitting and winding process, resulting in a fluffy roll with a larger volume.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings:

[0036] Example 1 provides a non-woven fabric slitting, winding, and holding mechanism 5 with a cowhide-like texture, such as... Figures 1-5 As shown, it includes a retaining guide rail 51, a retainer 52, a retaining shaft 53, a retaining roller 54, and a third driver 57;

[0037] Keep guide rail 51 mounted on frame 11 of slitting and winding machine 1;

[0038] The retainer 52 is slidably mounted inside the retaining guide rail 51;

[0039] A retaining shaft 53 is provided on one side of the retainer 52, and the retaining roller 54 is mounted on the retaining shaft 53; the retaining roller 54 is arranged opposite to the core 44 of the winding mechanism 4;

[0040] The output of the third driver 57 is connected to the cage 52.

[0041] The third driver 57 drives the retainer 52 and retaining roller 54 to move towards the core of the winding mechanism 4, as follows: Figure 4 It maintains the tension of the imitation cowhide-textured non-woven fabric 7, while also smoothing the core and preventing the roll from becoming fluffy due to the rebound of the imitation cowhide-textured non-woven fabric 7.

[0042] The axis of the holding roller 54 can be on the same horizontal plane as the axis of the take-up roller 43; preferably, the axis of the holding roller 54 is higher than the axis of the take-up roller 43 and lower than the upper horizontal section of the core 44. The upper horizontal section is located on the upper side of the core and is tangent to the core.

[0043] The third driver 57 is mounted on the retaining rail 51 via the mounting plate 56, or on the frame 11. The third driver 57 is a linear driver, and can be of various types.

[0044] like Figure 3 A take-up frame 12 is provided on one side of the frame 11, and two sets of take-up assemblies 41 of the take-up mechanism 4 are respectively provided on the upper and lower sides of the take-up frame 12. The cores 44 on the two take-up rollers 43 are staggered in a horizontal position.

[0045] The take-up assembly 41 also includes a mounting base 42 disposed on the take-up frame 12, and the take-up roller 43 is rotatably mounted on the mounting base 42; as Figure 5 The output of the second driver 46 on the frame 11 is connected to the take-up roller 43 via the transmission assembly 45.

[0046] like Figure 2 The frame 11 is equipped with a transmission mechanism 3 and a slitting mechanism 2. The transmission mechanism 3 includes a plurality of guide rollers 31 spaced apart on the frame 11. The slitting mechanism 2 includes a support 26 mounted on the frame 11; a transmission rod 23 is rotatably mounted on the support 26, and one or more cutters 21 are mounted on the transmission rod 23. The output end of the first driver 22 is connected to the transmission rod 23.

[0047] Figure 1 The diagram also shows a supply mechanism 13 for imitation cowhide nonwoven fabric, which can be a supply roll or an upstream production device, such as the imitation cowhide nonwoven fabric being dried in a dryer and then entering a slitting and winding machine 1 for slitting and winding, but is not limited to this.

[0048] More specifically, a pressure roller 25 is provided on the lower side of the support 26 to cooperate with the cutter 21; the imitation leather-like non-woven fabric 7 is conveyed on the upper side of the pressure roller 25. The cutter 21 presses on the pressure roller 25 from above to cut the imitation leather-like non-woven fabric 7. Figure 3 An axial adjustment assembly 6 is shown, which is disposed on one side of the mounting base 42 and is used to adjust the axial position of the take-up roller 43. The axial adjustment assembly is prior art and will not be described in detail in this utility model.

[0049] Example 2 provides a tension-controllable holding mechanism 5, such as Figure 4 A tension sensor 55 is provided on the boss on the front side of the retainer 52, and the retaining shaft 53 is mounted on the detection end of the tension sensor 55. The tension sensor 55 is used to detect the pressure between the retaining shaft 53 and the retaining roller 54, and adjusts the stroke of the third drive 57 according to the pressure value to regulate the pressure within a certain constant range.

[0050] More specifically, the tension sensor 55 is connected to the PLC microcontroller, and the PLC microcontroller is connected to the control terminal of the third driver 57. The installation method of the PLC microcontroller is existing technology, and it can be an ARM or STEM32 microprocessor, but is not limited to these.

[0051] Example 3 provides a scheme in which multiple cores 44 are arranged on a take-up roller 43. The upper take-up roller has two or more cores 44, and the lower take-up roller 43 has two or more cores 44. The cores on a single take-up roller are arranged at intervals; the cores 44 on the upper and lower take-up rollers 43 are staggered. Figure 6 The diagram shows the distribution of four cores. Correspondingly, the number of cutters 21 on the slitting mechanism 2 should be increased to three, and the distribution of the cutters 21 should correspond to the distribution of the cores.

[0052] This invention uses a retaining mechanism 5 to hold the slit imitation leather-textured nonwoven fabric 7 onto the core 44, maintaining the tension of the core 44 while smoothing the roll to prevent it from springing back and loosening, ensuring a tight roll and improving the efficiency of slitting and winding. Through the cooperation of the tension sensor 55 and the third actuator 57, the roll is kept within a certain tension range, preventing the tension from increasing due to the increase in the roll diameter during winding.

[0053] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
