Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyurethane imitation microfiber technology, and in particular to a polyurethane imitation microfiber molding device. Background Technology
[0002] Polyurethane microfiber-like fibers are synthetic materials that combine the properties of polyurethane (PU) and microfiber, primarily used as a substitute for genuine leather or high-grade microfiber leather. The molding process of polyurethane microfiber-like fibers involves a heating step, where drying and heating promote the cross-linking and curing of the polyurethane resin, enhancing the material's structural stability. Because polyurethane microfiber-like fibers vary in thickness, differences in the distance between the fibers and the heat source during heating can affect the heating and molding results, especially when molding fibers of varying thicknesses. Utility Model Content

A threaded cylinder is rotatably connected to the top wall of the box body via bearings. A threaded column is threadedly connected to the inner wall of the threaded cylinder. The threaded cylinder is rotated by a rotating mechanism. A connecting plate is fixedly connected to the threaded column. Multiple heating resistors are fixedly connected at equal intervals on the connecting plate.
[0006] Preferably, the rotating mechanism includes a gear, which is fixedly connected to the threaded cylinder. A rack meshes with the gear, and a connecting rod is fixedly connected to the rack. The connecting rod is fixed by a fixing mechanism.
[0007] Preferably, the fixing mechanism includes a connecting sleeve, which is fixedly connected to the housing, the connecting rod passes through the connecting sleeve, and a fastening bolt is threaded through the connecting sleeve.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] Example 1: Refer to Figure 1-3A polyurethane imitation microfiber molding device includes a housing 1, on which a temperature controller is installed to control and regulate the temperature inside the housing 1. Multiple conveying rollers 10 are rotatably connected to the inner wall of the housing 1 via bearings. Motors 9 are driven to the conveying rollers 10 at both ends, causing them to rotate and move the polyurethane imitation microfiber placed on them. The motors 9 are mounted on the housing 1. A threaded cylinder 5 is rotatably connected to the top wall of the housing 1 via bearings. A threaded post 11 is threadedly connected to the inside of the threaded cylinder 5. The threaded cylinder 5 rotates via a rotating mechanism. A connecting plate 12 is fixedly connected to the threaded post 11. Multiple heating resistors 13 are fixedly connected at equal intervals on the connecting plate 12. The rotating mechanism drives the threaded cylinder 5 to rotate, thereby adjusting the position of the threaded post 11 within the threaded cylinder 5. Moving the connecting plate 12 adjusts the position of the heating resistors 13, thus adjusting the distance between the heating resistors 13 and the surface of the polyurethane imitation microfiber. This ensures that the distance to the heating resistors 13 is the same when molding polyurethane imitation microfiber of different thicknesses, thereby guaranteeing the molding effect.
[0018] The rotating mechanism includes a gear 6, which is fixedly connected to the threaded cylinder 5. A rack 3 meshes with the gear 6, and a connecting rod 4 is fixedly connected to the rack 3. The connecting rod 4 is fixed by a fixing mechanism. The movement of the rack 3 drives the gear 6 to rotate, which in turn drives the threaded cylinder 5 to rotate, thereby adjusting the position of the threaded column 11 in the threaded cylinder 5.
[0019] Example 2: Refer to Figure 4 As another preferred embodiment of this utility model, based on embodiment 1, the fixing mechanism includes a connecting sleeve 8, which is fixedly connected to the housing 1. The connecting rod 4 passes through the connecting sleeve 8, and a fastening bolt 7 is threaded through the connecting sleeve 8. By tightening the fastening bolt 7, the fastening bolt 7 abuts against the connecting rod 4, thereby fixing the position of the connecting rod 4 and fixing the position of the rack 3.
[0020] Example 3: Reference Figure 1-3 As another preferred embodiment of this utility model, based on embodiment 2, a vertical plate 14 is fixedly connected to the connecting plate 12, and a pressing wheel is fixedly connected to the vertical plate 14. The pressing wheel is located at the opening of the box 1 for position observation. The pressing wheel is located directly above the conveying roller 10. When adjusting the position of the connecting plate 12, it is sufficient to adjust it until the pressing wheel abuts against the polyurethane imitation microfiber on the conveying roller 10. This ensures that the distance from the upper surface of the polyurethane imitation microfiber to the heating resistor 13 is constant during each adjustment, thus ensuring the heating and molding effect.
[0021] Example 4: Reference Figure 1-3In another preferred embodiment of this utility model, based on embodiment 1, a limiting rod 2 is fixedly connected to the connecting plate 12. The limiting rod 2 penetrates the box body 1. By using the limiting rod 2, the connecting plate 12 is limited, thus preventing the connecting plate 12 from rotating.
[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
