Embodiment 1

[0016] Such as figure 1 , image 3 As shown, the reel centering device for nonwoven fabrics of the present invention includes two fixed shafts 1 and three centering clips located at both ends of the fixed shafts 1. The fixed shaft 1 is a hollow shaft body, and the centering clips specifically include shells. body 2 and the first top body 5, the shell 2 is a sleeve with an I-shaped longitudinal section, and one side of the I-shape is the first groove 3, and the other side of the I-shape is the second groove 4, and the first groove 3 is provided with a mandrel, the side wall of the mandrel is slidingly connected with the inner wall of the housing 2, a sliding bearing 8 is arranged between the inner wall of the first groove 3 and the outer wall of the mandrel, and the end of the mandrel located in the housing 2 is in contact with the first recess Belleville springs 9 are arranged between the bottoms of the grooves 3, the other end of the mandrel is located outside the housing 2,...

Embodiment 2

[0019] Such as figure 2 and image 3 As shown, compared with Embodiment 1, in Embodiment 1, "the center of one end of the fixed shaft 1 is against the first tip body 5, and the other end of the fixed shaft 1 is against the second tip body 6" is replaced by: The center of one end of the fixed shaft 1 abuts against the first tip body 5, and the other end of the fixed shaft 1 abuts against the second tip body 6; Both ends of 1 are offset against the second top body 6.

[0020] The first tip body 5 on the left side of the first centering clip is not installed, and the second tip body 6 on the right side is installed, and the first tip body 5 and the second tip body 6 are respectively installed at both ends of the second centering clip. The left side of the third centering clip is equipped with the first tip body 5, and the right side is not equipped with the second tip body 6. The left end of the first fixed shaft 1 is offset against the second tip body 6 of the first centering...

Abstract

The invention discloses a reel centering device for non-woven fabrics. The reel centering device comprises fixing shafts and centering fixtures. The corresponding centering fixtures are positioned at two ends of each fixing shaft, each centering fixture comprises a shell and a first center, the shells are sleeves with H-shaped longitudinal sections, a first groove is formed in one side of the H-shaped longitudinal section side of each sleeve, a second groove is formed in the other side of the H-shaped longitudinal section side of each sleeve, a mandrel is arranged in each fist groove, a disc spring is arranged between the bottom of each first groove and the end, which is positioned in the corresponding shell, of the corresponding mandrel, the tails of the first centers are connected with the ends of the mandrels, and a cover further sleeves the side, which is positioned on the outside of the corresponding shell, of each mandrel and is detachably connected with the outer wall of the shell; conical expansion blocks are further arranged in the second conical grooves, and second centers are further connected with the end surfaces of the conical expansion blocks. The reel centering device for the non-woven fabrics has the advantages that the shortcoming of poor consistency of the bulkiness of existing non-woven fabrics can be overcome by the aid of the reel centering shaft, reels can be prevented from being offset, and the non-woven fabrics are consistent in bulkiness.

Description

technical field [0001] The invention belongs to the field of winding strip devices, in particular to a reel centering device for nonwoven fabrics. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers. They are a new generation of environmentally friendly materials. Low cost, recyclable and so on. For example, polypropylene (pp material) pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. It is called cloth because of its appearance and certain properties. [0003] Non-woven fabrics can be divided into: spunlace non-woven fabrics, hot-air non-woven fabrics, needle-punched non-woven fabrics, spunbonded non-woven fabrics, etc. Non-woven fabrics are formed by mechanically feeding fibers in various ways to form The softness of the non-woven fabric is good, especially the hot-air non-woven fabr...
