Description

Technical Field

[0001] The utility model relates to the technical field of cloth guiding, in particular to a cloth guiding mechanism of a loom. Background Art

[0002] A loom, also called a spinning machine, a weaving machine, a cotton spinning machine, etc., was an early human-driven loom. The loom was generally equipped with a cloth guiding mechanism to guide the woven fabric into the next processing link.

[0003] For example, in a cloth guide machine of a loom with patent publication number CN218619442U, when the pull block is pulled, the pull block is forced to drive the moving block to slide upward. At this time, the sliding of the moving block causes the limiting shaft to slide downward inside the limiting groove. Therefore, as the angle of the limiting groove becomes smaller, the clamping rod is restricted by the limiting shaft and detached from the inside of the clamping groove. At this time, the limiting ring can be easily moved, thereby changing the distance between the two limiting rings, so that the limiting ring can limit fabrics of different widths, thereby preventing the fabric from being offset during the transportation process, thereby ensuring the subsequent processing effect of the fabric.

[0004] However, when the above-mentioned device guides fabrics with different elasticity due to different materials, the second guide roller whose position cannot be adjusted cannot adjust the position according to different fabrics to change the pressure on the fabrics. This results in that when guiding some fabrics with average elasticity, the fabrics may be damaged due to excessive pressure. If the fabrics have good elasticity, the fabrics may be wrinkled during transportation due to insufficient pressure, which is not practical enough. Utility Model Content

[0025] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: a cloth guiding mechanism of a loom, comprising a guiding mechanism 1, the guiding mechanism 1 comprising two main boards 101, a first guiding roller 102 and a second guiding roller 103 are rotatably mounted between the two main boards 101, a first adjusting mechanism 2 for adjusting the position of applying pressure to the cloth is arranged on one side of one main board 101, and a second adjusting mechanism 3 for adjusting the size of the guideable cloth is arranged on the top of the guiding mechanism 1;

[0026] The first adjustment mechanism 2 includes two first fixing plates 201, and the two first fixing plates 201 are fixedly installed on one side of one of the main boards 101.

A first notch 204 and a second notch 206 are opened on one side of the first sliding rod 203. A first motor 205 is fixedly installed in the first notch 204, and a first motor 205 for up-and-down adjustment is rotatably installed in the second notch 206.

[0027] It should be noted that when in use, by rotating the second motor 209 forward or reversely, driving the first unidirectional threaded rod 202 to rotate forward or reversely, the first sliding rod 203 can be driven to slide left or right, and the position of the pressure roller 210 can be adjusted left or right. By rotating the first motor 205 forward or reversely, driving the second unidirectional threaded rod 207 to rotate forward or reversely, the first connecting plate 208 can be driven to slide upward or downward, and the position of the pressure roller 210 can be adjusted upward or downward.

[0028] Among them, the second adjustment mechanism 3 includes two second fixed plates 301, and the two second fixed plates 301 are respectively fixedly installed on the top of the two main boards 101, and a bidirectional threaded rod 302 is rotatably installed between the two second fixed plates 301. The outer wall of the bidirectional threaded rod 302 is connected to two sliding sheets 303 through a threaded sliding sleeve, and the bottoms of the two sliding sheets 303 are fixedly connected to limit rings 304 for limiting the size of the cloth, and the two limit rings 304 are slidably sleeved on the outer wall of the first guide roller 102, and a third motor 305 for driving the bidirectional threaded rod 302 to rotate is fixedly installed on one side of one of the second fixed plates 301.

The first motor 205 is started to drive the second one-way threaded rod 207 to rotate, so that the position of the pressure roller 210 can be adjusted in the up and down directions. The cooperation between the first one-way threaded rod 202 and the second one-way threaded rod 207 improves the adjustability of the pressure roller 210.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
