Description
Technical Field
[0001] The utility model relates to the technical field of water jet looms, in particular to a fixed rear beam which is easy to install. Background Art
[0002] The frictional traction of water jet weft insertion on the warp yarn is greater than that of air jet weft insertion, and its diffusion is small. It is suitable for the weft insertion of smooth-surfaced synthetic fibers, glass fibers and other filaments. At the same time, it can increase the conductivity of synthetic fibers and effectively overcome static electricity in weaving. In addition, jetting warp yarn consumes less energy and has the lowest noise.
[0003] Some equipment on the market generally loosens the fasteners, pushes the movable bearing seat, rear beam shaft, rear beam swing bearing seat, swing rear beam and fixed rear beam by hand, and each part slides down along the slideway with the rotating shaft as a circle until the movable bearing seat is stuck by the platform on the rear beam seat, and then tightens the fasteners. At this time, the rear beam is in a state where it can be turned on and operated.
[0004] However, in actual use of the above equipment, when the fixed rear beam is excessively worn out after long-term use and needs to be replaced, the rear beam shaft needs to be taken out for replacement. However, the rear beam shaft and the fixed rear beam are too heavy, and it is not convenient to connect the rear beam shaft and the fixed rear beam during the delicate replacement. In view of this, we propose a fixed rear beam that is easy to install. Utility Model Content

[0015] Compared with the prior art, the utility model provides a fixed rear beam that is easy to install and has the following beneficial effects:
[0016] 1. The fixed rear beam which is easy to install is used to avoid the inconvenience of replacing the fixed rear beam after being worn. When the fixed rear beam needs to be replaced after long-term use, the rear beam shaft is pushed to make the embedded block press the movable part, and the movable part compresses the spring to make the limit block move inside the limit groove. The limit groove is J-shaped. The embedded block is rotated to make the limit block move to the long vertical part of the limit groove. In this way, the embedded block is released from the limit and is subjected to the elastic force of the spring, so that the embedded block can be taken out from the fixed groove, and the rear beam shaft is taken out from the fixed groove. This can make the fixed rear beam released from the limit and can be quickly replaced.
[0017] 2. The fixed rear beam which is easy to install, in order to avoid the swinging rear beam and to clamp the swinging bearing seat more stably, after replacing the fixed rear beam, adjust the angle of the swinging bearing seat so that the swinging rear beam is higher than the fixed rear beam or lower than the fixed rear beam, and then move the rotating block to move the rotating block toward the swinging bearing seat, and rotate the rotating block when it contacts the external thread provided on the outer surface of the rear beam shaft, which can make the swinging bearing seat contact with one side of the embedded block, so that the swinging bearing seat can be better limited.

The external thread 19 is arranged on the outer surface of the rear beam shaft 9 near the swing bearing seat 10, and the external thread 19 is meshed with the internal thread arranged inside the rotating block 20. A rotating block 20 is arranged on the outer surface of the rear beam shaft 9, a fixed rear beam 11 is arranged on the outer surface of the rear beam shaft 9, a swing bearing seat 10 is arranged on the outer surface of the rear beam shaft 9, a swing rear beam 12 is arranged on one side of the swing bearing seat 10, and a limiting device is arranged on one side of the fixed rear beam 11, and the limiting device includes a fixing groove 13, a limiting groove 15, a spring 14, a movable part 16, an embedded block 17 and a limiting block 18.
[0024] In an embodiment of the utility model, a fixed groove 13 is provided on one side of the fixed rear beam 11, and a limiting groove 15 is provided on the arc-shaped inner wall of the fixed groove 13. The limiting groove 15 is arranged in a J shape. A spring 14 is fixedly connected to the bottom of the inner wall of the fixed groove 13, and a movable part 16 is fixedly connected to one end of the spring 14. The movable part 16 is arranged in a circular ring shape, and the size of the movable part 16 is adapted to the size of the fixed groove 13, which allows the movable part 16 to move inside the fixed groove 13.
