Description

Technical Field

[0001] The utility model relates to the technical field of composite material production devices, in particular to a polyurethane composite material pultrusion production device. Background Art

[0002] Polyurethanes can be classified into different types based on their chemical structure and properties. For example, thermoplastic polyurethane (TPU) has good processing properties and can be formed through processing methods such as injection molding and extrusion. It also has high flexibility and elastic recovery ability and is widely used in fields such as shoe soles and pipes. Reactive polyurethanes (such as two-component polyurethanes) can form a highly cross-linked network structure after curing, have excellent mechanical properties and chemical resistance, and are commonly used in coatings, adhesives, etc. The pultrusion process, as a continuous production process, has great advantages in the field of composite material production. In the patent document with the published publication number CN111748073B, a method for preparing a polyurethane pultruded composite material is disclosed. This solution achieves improved production efficiency by improving the polyurethane composite material pultrusion process method and mold through the provision of a yarn guide device, an impregnation device, a mold, a traction device, and a heating device. However, in the existing preparation process, the initial tension of the polyurethane matrix is ​​affected during the pultrusion operation of the material, so that the distribution uniformity of the fibers in the polyurethane matrix is ​​low during the subsequent impregnation and pultrusion molding process, making it difficult to ensure the consistency of the composite material. Therefore, the present application proposes a composite material pultrusion production device capable of improving the uniformity of fibers in a polyurethane matrix. Summary of the Invention

[0030] Example

[0031] like Figure 1 As shown, the present invention proposes a polyurethane composite material pultrusion production device, which includes a creel body 2, a first heating device 3, a second heating device 4, a die device 7, and a traction device 6 arranged in sequence. The pultrusion production device also includes a polyurethane composite material fiber body 1 to be processed and a profile body 5. The creel body 2 also includes a frame 21, on which a plurality of spindles 22 are mounted.

[0032] like Figure 2-4 As shown, one side of multiple groups of spindles 22 is equipped with a tension adjustment assembly 8 located on the frame 21, and the tension adjustment assembly 8 includes a fixed rod 81 fixedly arranged on one side of the spindle 22, one end of the fixed rod 81 is welded to the frame 21, and a plurality of limiting holes 810 are arranged in an array along its length direction; a sliding frame 82 is slidably sleeved on the fixed rod 81, and a rectangular opening is provided on the top of the sliding frame 82, and the rectangular opening is adapted to the inner diameter of the limiting hole 810, and a group of limiting holes 810 and the rectangular opening are clamped with a clamp 83, which is used to adjust the distance between the guide wheel 86 and the frame 21, thereby adapting to the outlet guide at different positions; the bottom of the sliding frame 82 is fixedly connected to a mounting plate 84, and the mounting plate 84 is an "L"-shaped plate, and the upper side of the mounting plate 84 is rotated and mounted A guide wheel 86 is provided, which is located below the sliding frame 82, and a connecting rod 85 is connected to the guide wheel 86 and is rotatably connected to the side wall of the mounting plate 84. A lifting guide wheel 842 with adjustable height is provided on the lower side of the mounting plate 84. The lifting guide wheel 842 is used to tension the conductive polyurethane profile. A lifting groove 840 is provided on the mounting plate 84, and a card hole 843 is provided on one side of the lifting groove 840, which passes through the mounting plate 84. A card rod 844 is movably inserted in the card hole 843. A lifting block 841 is provided in the lifting groove 840 for sliding and lifting. The lifting guide wheel 842 is rotatably connected to one side of the lifting block 841. The lifting block 841 is made of ceramic. A card slot 845 is provided on one side of the lifting block 841, and one end of the card rod 844 passes through the card hole 843 and is clamped in the card slot 845.

[0033] In this embodiment, the polyurethane linear profile being transported and extruded is guided by the creel body 2.

When the transported polyurethane composite linear profile is tensioned, the clamping rod 844 is inserted into the clamping slot 845 corresponding to the position of the clamping hole 843 to fix the position of the lifting block 841, thereby guiding the tension transmission of the profile.

[0034] If the same polyurethane composite linear profile needs to be relaxed, the height of the lifting guide wheel 842 is increased to reduce the tension;

[0035] In this embodiment, the guide distance between the guide wheel 86 and the frame 21 is adjusted by means of the limiting hole 810 and the sliding frame 82, thereby avoiding entanglement caused by the same transmission path of multiple groups of linear profiles and ensuring the stability of polyurethane composite material production.

[0036] The above specific embodiment is only an optional embodiment of the present invention.
