Description

Technical Field

[0001] This utility model relates to the field of adhesive scraping technology, specifically to a yarn pressing roller assembly. Background Technology

[0002] In fiber winding machinery, especially fiberglass pipe and can winding equipment, yarn tension control, guidance, and surface treatment are key aspects to ensure product quality and production efficiency. The yarn pressing device is one of the core components of this type of equipment. Its main function is to apply stable and adjustable pressure to the running yarn, ensuring it passes smoothly and tightly through the processing area, or to work with a scraping device to remove excess sizing and adhesive from the yarn.

[0003] Existing yarn pressing devices typically consist of fixed pressing rollers and simple scraper structures. However, these traditional structures have several significant limitations: First, the pressure exerted by the pressing rollers on the yarn is often fixed or has a limited adjustable range, making it difficult to conveniently and accurately adapt to the varying pressure requirements of different yarn counts, materials, or processes, thus affecting tension uniformity. Second, the scraping components are mostly fixedly installed, making it difficult to flexibly adjust their position according to the characteristics of the adhesive or yarn specifications. Furthermore, cleaning and replacement are inconvenient, easily leading to incomplete adhesive application or yarn damage. Third, the installation and fixing methods for the yarn feeding and pressing assemblies in the traditional adhesive trough are often cumbersome, requiring various tools, which is time-consuming and labor-intensive during equipment maintenance and product changes, affecting production continuity. In addition, traditional structures are insufficient in terms of space utilization and modularity, making them unsuitable for integration into more automated production lines.

[0004] Therefore, there is an urgent need for an improved yarn pressing roller assembly that can achieve convenient and linear adjustment of yarn feeding and pressing pressure, has adjustable glue scraping position and is easy to maintain, and whose overall structure is easy to install, fix and adjust to a certain extent, so as to meet the high efficiency, flexibility and high quality requirements of modern fiber winding tube and can production.

[0019] The specific technical solutions of this utility model are further described below with reference to the accompanying drawings, so as to enable those skilled in the art to further understand this utility model, without constituting a limitation on its rights.

[0020] Example 1, referring to Figure 1-3 A yarn pressing roller assembly includes a yarn pressing frame 7 having; The yarn pressing roller assembly includes a yarn pressing roller 1, a guide shaft 2, a compression spring 3, a pressure plate 4, and a nut 5. The two ends of the yarn pressing roller 1 are horizontally embedded in the top center of the yarn pressing frame 7, forming a roughly roller-shaped structure. A U-shaped groove 6 is formed on the top center of the yarn pressing frame 7 to accommodate the two ends of the yarn pressing roller 1. The guide shaft 2 is vertically fixed to the top surface of the yarn pressing frame 7 beside the yarn pressing roller 1, and has external threads on its outer circumference. The guide shaft 2 is a cylindrical shaft structure. The compression spring 3 is sleeved on the outer circumferential surface of the guide shaft 2. The compression spring 3 can also be a spring. The pressure plate 4 is passed through the guide shaft 2 and placed between the top of the yarn pressing roller 1 and the bottom of the compression spring 3. The pressure plate 4 is formed into a horizontally arranged square plate structure. The nut 5 is screwed onto the outer circumferential surface of the guide shaft 2. There are two yarn pressing rollers 1. Each yarn pressing roller 1 has a guide shaft 2 on its side. Each guide shaft 2 has a compression spring 3, a pressure plate 4 and a nut 5. When it is necessary to adjust the pressure of the pressure plate 4 on the yarn pressing roller 1, the pressure spring 3 can be compressed by rotating the nut 5, and the elastic potential energy of the pressure spring 3 can be used to apply pressure to the pressure plate 4, thereby increasing the pressure on the yarn pressing roller 1. Two yarn pressing frames 7 are provided, and the two yarn pressing frames 7 are parallel to each other. The yarn pressing frames 7 are formed into a roughly rod-shaped structure. The yarn pressing roller assembly and the glue scraping assembly are installed between the two yarn pressing frames 7. Each yarn pressing frame 7 has a limiting block 8 and a flipping bracket 9. Two support rods 10 are vertically fixed between the two yarn pressing frames 7. The support rods 10 are rod-shaped structures. The glue scraping rod, the yarn pressing roller 1, and the support rods 10 are parallel to each other. Several handles 18 are vertically fixed on the outer wall of the yarn pressing frame 7. The glue-scraping assembly includes a limiting plate 11, an adjusting block 12, and a glue-scraping rod 13. The limiting plate 11 is fixed to the top of one end of the yarn pressing frame 7 and is roughly square in shape. The adjusting block 12 is detachably mounted on the bottom of the yarn pressing frame 7 below the limiting plate 11 via a connector. For example, a screw is vertically fixed on the top surface of the adjusting block 12, which passes through the limiting plate 11, and a connecting nut is screwed onto the top of the screw. By rotating the connecting nut 14, the height of the adjusting block 12 and the glue-scraping rod 13 can be adjusted. The glue-scraping rod 13 is horizontally fixed to the bottom of the adjusting block 12. Two limiting blocks 8 are provided, which are formed into a roughly square block structure. The two limiting blocks 8 are located on the outer wall of the yarn pressing frame 7 on both sides of the glue scraping assembly. The two limiting blocks 8 are symmetrically arranged on the yarn pressing frame 7. The flipping bracket 9 is detachably mounted on the end of the yarn pressing frame 7 away from the glue scraping assembly. It is formed into a roughly square plate structure and is horizontally arranged. A vertical plate is fixedly mounted on its top. The plate is also formed into a square plate structure. The middle part of the plate is hinged to the end of the yarn pressing frame 7. A support 15 is fixedly mounted at the bottom of the flipping bracket 9. The support 15 is also formed into a roughly square plate structure. Several bolt holes 16 are opened at the bottom of the support 15. The top surface of the limiting block 8 and the top surface of the support 15 are formed with pressing planes 17 for external quick clamps to apply force. When it is necessary to fix the yarn pressing frame 7, the limiting block 8 and the support 15 can be pressed by external quick clamps to achieve the installation limit of the yarn pressing roller assembly.

[0021] The operating principle of the yarn pressing roller assembly in Example 1 is as follows: First, the assembled yarn pressing roller assembly is placed at the designated station of textile equipment such as a warp knitting machine or a coating machine. Using external quick clamps, the assembly is pressed onto the pressing planes 17 on the top surface of the limit block 8 and the top surface of the support 15. The clamps quickly and firmly clamp the entire assembly onto the equipment frame. If further tightening is required, the bolt holes 16 at the bottom of the support 15 can be connected to the bolts on the outer wall of the external equipment using bolt fasteners to meet the requirements of higher stability. The pressure of the yarn pressing roller 1 can be adjusted according to the type, thickness, and tension requirements of the yarn to be processed. The operator compresses the compression spring 3 by rotating the nut 5 on each guide shaft 2, thereby transmitting the increased elastic pressure to the lower yarn pressing roller 1 through the pressure plate 4, increasing the pressure on the yarn. Conversely, loosening the nut 5 reduces the pressure. When the process involves scraping glue, the scraping glue assembly needs to be adjusted in advance. By loosening the connecting nut 14 between the adjusting block 12 and the limiting plate 11, the adjusting block 12 can be moved up and down, thereby changing the height of the scraping rod 13 relative to the yarn running path. After adjustment, the connecting nut 14 can be tightened to fix it. This design allows the scraping action to adapt to different viscosities of glue or coating, ensuring the best scraping effect without damaging the yarn. Its structural design is reasonable and easy to install and disassemble.
