AI Technical Summary
The reed in traditional looms tends to wear out at the same position, resulting in reduced weaving efficiency.
The push-up roller is changed to an elliptical structure, with the radius of the long axis 2mm-3mm longer than the short axis. The transmission rod is driven to swing through the tangential motion of the ellipse and the roller, thereby realizing a small periodic motion of the loom roller, increasing the friction points of the warp yarn, and improving the wear resistance of the reed.
By increasing the friction points, the wear of the reed is reduced and the weaving efficiency is improved.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of textile equipment, in particular to a device for improving the wear resistance of a reed and a push-down roller thereof. Background Art
[0002] During the weaving process, the reed moves back and forth to tighten the weft yarns after beating them up. Because the warp and weft yarns move up and down in a specific weave pattern, traditional weaving equipment can easily cause wear and tear on the reed, leading to reduced weaving efficiency.
[0003] like Figure 1 As shown, the loom has a circular push-up roller 1, roller 2, transmission rod 3, cloth-feed roller 4 and reed 5. The push-up roller 1 is tangent to the roller 2, and the transmission rod 3 is sleeved on the roller 2. When weaving, the push-up roller 1 will drive the roller 2 to rotate when it rotates. At this time, since the relative positions of the push-up roller 1 and the roller 2 remain unchanged, the transmission rod 3 sleeved on the roller 2 and the roller 2 remain unchanged relative to each other, so the force transmitted from the transmission rod 3 to the cloth-feed roller 4 remains unchanged (excluding the factor of machine startup vibration), and the cloth-feed roller 4 remains stationary relative to the reed 5. When the reed 5 moves back and forth, the warp yarn will rub against the same position of the reed 5 at the cloth-feed, causing the reed 5 to be easily damaged.
[0004] In view of this, the present invention is conceived in depth to solve the problem of easy wear of the reed in the existing loom, and the present invention is developed through active research, improvement and trial production. Utility Model Content
[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a device and a push-down roller thereof that can improve the wear resistance of a reed.
[0006] In order to achieve the above objectives, the solution of the present invention is:
[0007] A push-up roller has an elliptical structure, and the radius of the long axis is 2mm-3mm longer than the radius of the short axis.
[0008] A device for improving the wear resistance of a reed, comprising a push-down roller, a roller, a transmission rod, a cloth-fell roller and a reed. The push-down roller is an elliptical structure, comprising a short axis and a long axis, the radius of the long axis being 2 mm to 3 mm longer than that of the short axis. The push-down roller is circumscribed to the roller, the transmission rod is sleeved on the roller, the cloth-fell roller is mounted at the front of a loom, close to the position where the fabric is formed, and the reed is transversely mounted in the beating area of the loom, at the position where the warp and weft yarns are interwoven.
[0009] After adopting the above structure, the device of the utility model can improve the wear resistance of the steel reed by improving the circular structure of the push-down roller into an elliptical structure. When weaving, since the elliptical push-down roller is tangent to the roller, when the push-down roller rotates, it will drive the roller to rotate. At this time, since the radius of the tangent between the push-down roller and the roller will change, the transmission rod on the roller will swing. When the roller moves from the short axis to the long axis, the transmission rod will drive the cloth-feed roller to move slightly upward. When the push-down roller moves from the long axis to the short axis, the transmission rod will drive the cloth-feed roller to move slightly downward. Therefore, the cloth-feed roller will form a small periodic motion at the cloth-feed, thereby driving the warp yarn to have a small periodic motion. When the steel reed moves back and forth, the warp yarn will rub at different positions of the steel reed at the cloth-feed, thereby increasing the friction points and improving the wear resistance of the steel reed.

[0012] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.
[0013] In the description of the present invention, it should be understood that terms such as "center," "longitudinal," "lateral," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.
[0014] like Figure 2As shown, the utility model discloses a device for improving the wear resistance of a reed, comprising a push roller A, roller B, a drive rod C, a cloth-fell roller D, and a reed E. Push roller A is an elliptical structure, including a short axis A1 and a long axis A2. The radius of the short axis A1 of the improved elliptical push roller A maintains the radius of a traditional circular push roller, while the radius of the long axis A2 is 2mm-3mm longer than that of a traditional circular push roller, i.e., the radius of the long axis is 2mm-3mm longer than the radius of the short axis. Push roller A and roller B are circumscribed, the drive rod C is sleeved onto roller B, the cloth-fell roller D is mounted at the front of the loom, near the fabric forming position, and the reed E is mounted transversely in the beating-up area of the loom, where the warp and weft yarns intertwine.
[0015] The device for improving the wear resistance of the reed of the present invention improves the circular structure of the push-down roller into an elliptical structure. During weaving, since the elliptical push-down roller A is tangent to the roller B, when the push-down roller A rotates, it will drive the roller B to rotate. At this time, since the radius of the tangency between the push-down roller A and the roller B will change, the transmission rod C mounted on the roller B will swing. When the roller B moves from the short axis to the long axis, the transmission rod will drive the cloth-feed roller to move slightly upward. When the push-down roller moves from the long axis to the short axis, the transmission rod will drive the cloth-feed roller to move slightly downward. Therefore, the cloth-feed roller will form a small periodic motion at the cloth-feed, thereby driving the warp yarn to have a small periodic motion. When the steel reed moves back and forth, the warp yarn will rub against different positions of the steel reed at the cloth-feed, thereby increasing the friction points and improving the wear resistance of the steel reed.
[0016] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
