[0002] Polypropylene is a synthetic fiber produced from propylene, a byproduct of petroleum refining, through polymerization and melt spinning. Also known as polypropylene fiber, polypropylene comes in various types, including filaments (including untextured and expanded textured filaments), staple fibers, fiber bristles, split-film fibers, hollow fibers, profiled fibers, various composite fibers, and nonwoven fabrics. Its main uses include the production of carpets (including carpet backing and pile), decorative fabrics, furniture fabrics, various ropes, strips, fishing nets, oil-absorbing felt, building reinforcement materials, packaging materials, and industrial fabrics such as filter cloths and bag fabrics.
[0003] Before twisting high-strength polypropylene yarn, it is usually necessary to adjust the tension of multiple high-strength polypropylene yarns to a suitable strength. However, in the existing technology, the tension of each high-strength polypropylene yarn usually needs to be adjusted individually, which results in low adjustment efficiency and increases the labor intensity of workers. Therefore, we have introduced an adjustable high-strength polypropylene yarn padlock. Utility Model Content
[0004] The purpose of this invention is to provide an adjustable high-strength polypropylene yarn padlock that allows for simultaneous tension adjustment of multiple high-strength polypropylene yarns before the twisting process, thereby improving adjustment efficiency and reducing the labor intensity of workers, thus solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An adjustable high-strength polypropylene filament padlock includes a base. Multiple U-shaped frames are fixedly mounted on the upper end of the base. Tension rollers are rotatably mounted on the upper side of each U-shaped frame via a rotating shaft. Adjacent tension rollers are arranged perpendicularly to each other. A locking ring is provided between the tension rollers. A vertical rectangular rod is provided below the locking ring via a connecting structure. The rectangular rod has a cavity inside. A rectangular tube is slidably mounted outside the rectangular rod. The lower end of the rectangular tube is fixedly connected to the base. A through hole is provided at the lower end of the side wall of the rectangular tube. An adjustment mechanism is provided between the through hole and the rectangular rod.
[0007] As a further embodiment of this utility model, the adjusting mechanism includes a rotating shaft, which is rotatably disposed in a through hole via a rolling bearing. Both ends of the rotating shaft extend to the outside of the through hole. A first bevel gear is provided at one end of the rotating shaft. A threaded hole is provided in the middle of the lower end of the rectangular tube. A lead screw is threaded in the threaded hole. The lower end of the lead screw is rotatably connected to the base via a rolling bearing. A second bevel gear that cooperates with the first bevel gear is provided on the wall of the lead screw.
[0008] As a further embodiment of this utility model, the connection structure includes multiple support rods, which are fixedly disposed at the bottom of the locking ring, and the lower ends of the multiple support rods are fixedly connected to the upper ends of the rectangular rods. The multiple support rods are respectively disposed between multiple U-shaped frames.
[0009] As a further embodiment of this utility model, a rotating wheel is fixedly provided at one end of the rotating shaft located outside the rectangular tube.
[0010] As a further embodiment of this invention, the circumferential wall of the wheel is provided with multiple anti-slip grooves.
[0011] As a further embodiment of this utility model, limiting rings are fixedly provided at both ends of the tension roller.
[0012] As a further embodiment of this invention, the outer diameter of the limiting ring is larger than the diameter of the tension roller.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This adjustable high-strength polypropylene filament padlock consists of a rectangular tube, a rotating wheel, a U-shaped frame, a base, a tension roller, a limit ring, a support rod, a locking ring, a rectangular rod, a lead screw, a second bevel gear, a first bevel gear, a rotating shaft, and an anti-slip groove. Multiple high-strength polypropylene filaments pass under the tension rollers, then between two corresponding support rods, and finally twist upwards around the locking ring. To adjust the tension of multiple high-strength polypropylene filaments, the rotating wheel is rotated, which in turn drives the rotating shaft. The shaft then drives the corresponding first bevel gear, which in turn drives the meshing second bevel gear. The second bevel gear drives the lead screw, which in turn moves the rectangular rod upwards or downwards. The rectangular rod, through the support rod, moves the locking ring, thus adjusting the contact area between the high-strength polypropylene filaments and the tension rollers, thereby adjusting the tension level of the high-strength polypropylene filaments. Before the twisting process, the tension of multiple high-strength polypropylene filaments can be adjusted simultaneously, improving adjustment efficiency and reducing the labor intensity of workers.
