Description

Technical Field

[0001] This utility model relates to the field of water jet loom technology, and in particular to the rear beam mechanism of a water jet loom. 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 provides greater frictional traction 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 electrical conductivity of synthetic fibers, effectively overcoming static electricity during weaving. Furthermore, water jet weft insertion consumes less energy and produces the lowest noise levels.

[0003] In existing water jet looms, the back beam system has a high coefficient of friction when the warp yarns are fed onto the transport rollers, which greatly reduces the transmission efficiency of the warp yarns. As a result, the yarns in current water jet looms are either too tight or too loose when being fed, which is not conducive to the operation of the water jet loom. Utility Model Content

[0004] In order to overcome the above-mentioned defects in the prior art, the present invention provides a rear beam mechanism for a water jet loom.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a rear beam mechanism of a water jet loom, including a water jet loom body, a sliding frame slidably mounted on the left outer side of the water jet loom body, a first mounting frame fixedly mounted on the upper left side of the sliding frame, a guide wheel movably mounted on the upper end of the first mounting frame via a first mounting shaft, a second mounting frame fixedly mounted on the upper middle part of the sliding frame, two sets of first sliders slidably mounted inside the second mounting frame, a pressure wheel movably mounted between the two sets of first sliders via a second mounting shaft, a third mounting frame fixedly mounted on the upper right side of the sliding frame, a second slider slidably mounted between the front and rear side walls of the third mounting frame, and a buffer wheel movably mounted between the two sets of second sliders via a third mounting shaft.

[0006] Furthermore, several sets of first telescopic devices are fixedly installed on the upper left side of the water jet loom body, and a sliding frame is fixedly installed on the telescopic end of the first telescopic device.

[0010] Furthermore, a woven thread is tensioned between the upper end of the guide wheel, the lower end of the pressure wheel, and the upper end of the buffer wheel.

[0011] The beneficial effects of this utility model are: the yarn is tensioned by the upper end of the guide wheel, the lower end of the pressure wheel and the buffer wheel; the longitudinal position of the yarn can be adjusted as a whole by activating the first telescopic device to adapt it to the water jet loom; the pressure wheel is pressed down by activating the second telescopic device, and at the same time the spring continues to press the buffer wheel, so that the tension of the yarn can be adjusted.
