Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically a water jet loom with a guiding structure. Background Technology

[0002] Water jet looms are shuttleless looms that use jets of water to guide the weft yarn through the shed. Water jet weft insertion exerts a greater frictional pulling force on the weft yarn than air jet weft insertion, with less diffusion, making it suitable for weft insertion of smooth-surfaced synthetic fibers, glass fibers, and other filaments. It also increases the conductivity of synthetic fibers, effectively overcoming static electricity during weaving. Furthermore, water jet weft insertion consumes less energy and produces the lowest noise.

[0003] For example, utility model patent CN211284753U discloses a textile thread guiding device for a water-jet loom that is easy to adjust, including a base, a first fixed rod and a guide roller. A support rod is connected to one side of the base, and a fixed frame is connected to the side of the base near the support rod. A connecting plate is provided on one side of the support rod. The first fixed rod is connected to the side of the connecting plate away from the support rod. A second fixed rod is provided on one side of the first fixed rod. A connecting rod is fixed to the side of the second fixed rod near the first fixed rod. Locking blocks are connected to both sides of the connecting rod. This easily adjustable water jet loom uses a yarn guide device. A rotating baffle, which passes through a second fixed rod, moves along one side of the second fixed rod via a threaded structure. This facilitates adjustment of the distance between the baffle and the yarn roller, allowing the baffle to press against one side of the yarn roller. It also accommodates yarn rollers of different sizes, preventing them from wobbling and affecting operation. However, it requires manual adjustment of the lead screw when adjusting the distance between the yarn roller and the guide roller. Furthermore, manual adjustment of the lead screw cannot be limited, leading to a reverse force on the lead screw when the yarn contacts the yarn roller, ultimately causing the lead screw to reverse and resulting in an unstable distance between the yarn roller and the guide roller. Therefore, we propose a water jet loom with a guide structure. Utility Model Content

[0004] The purpose of this invention is to provide a water jet loom with a guiding structure to solve the problems mentioned in the background art.

[0006] Preferably, the roller mounting assembly includes a rotating shaft, the outer end of which has a threaded groove, and a screw is threadedly connected to the inner wall of the threaded groove. A limit ring is fixedly connected to the left end of the outer wall of the rotating shaft, and a limit plate is fixedly connected to the outer end of the screw. The roller body is disposed between the limit plate and the limit ring.

[0007] Preferably, the spring is sleeved on the guide post, and the outer wall of the guide post is slidably connected to the guide roller body.

[0009] Preferably, multiple evenly distributed reinforcing ribs are fixedly connected to both sides of the vertical plate, and a base is fixedly connected to the lower end of each reinforcing rib.

[0010] Preferably, a power source is provided on the lower right side of the vertical plate, and the power source is located below the stepless adjustment assembly of the guide roller, and the power source is electrically connected to the electric push rod.

[0011] Preferably, the roller body is inserted into a rotating shaft, and the left end of the rotating shaft is rotatably connected to a vertical plate via a bearing.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Equipped with a base, vertical plate, wire roller mounting assembly, guide roller stepless adjustment assembly, reinforcing ribs, and power supply, this device allows for automatic adjustment of the distance between the guide roller body and the wire roller body. When adjustment of the distance is required, the power supply powers an electric push rod, which in turn moves a cone. Since the contact head and cone are always in contact, the movement of the cone causes the contact head and guide column to displace the moving arc plate, resulting in continuous compression of the spring. This invention enables automatic adjustment of the distance between the guide roller body and the wire roller body, and also locks the wire roller body in place after installation, preventing changes in the distance due to vibration and improving stability.

[0014] 2. The installation assembly for the wire roller allows for easy installation and removal of the wire roller body. First, the wire roller body is inserted into the rotating shaft, with the left end of the wire roller body abutting against the right end of the limiting ring. Next, the screw is screwed into the threaded groove. The rotating handle then drives the limiting plate and screw to rotate continuously until the left end of the limiting plate abuts against the right end of the wire roller body.
