Specifically, in actual production, the process requirements of the fabric of this heald frame for a loom may change, such as changing the fabric type or adjusting the warp density. By adjusting the height of the heald frame, these process changes can be quickly adapted to improve production flexibility and adaptability. For example, when thicker fabrics need to be produced, the height of the heald frame can be appropriately increased to increase the tension of the warp yarns and the height of the interweaving points, thereby increasing the thickness and strength of the fabric; when thinner fabrics need to be produced, the height of the heald frame can be lowered to reduce the tension of the warp yarns and the height of the interweaving points, thereby making the fabric lighter, thinner and softer. When the heald frame is in use, its use height can be easily adjusted, and it can meet the process requirements of different fabrics. When the movable side rod 4 is connected to the top beam 1, there is no need to install and fix it through multiple nuts.

[0026] like Figure 1 、 Figure 2 As shown, the fixing assembly 7 includes a connecting seat 701, the surface of the top beam 1 is fixedly connected to the connecting seat 701, the inner wall of the connecting seat 701 is rotatably connected to a threaded locking rod 702, the surface of the threaded locking rod 702 is threadedly connected to a butterfly nut 703, and the surface of the movable side rod 4 is fixedly connected to a fixing block 704; specifically, the setting of the fixing assembly 7, the connecting piece 11 is fixedly installed with the mounting column 2 in advance, when the movable side rod 4 is connected to the top beam 1, the bottom beam 12 can be fixedly connected to the mounting column 2 in advance, which will not affect the installation process of each component. At this time, the movable side rod When installing on the top beam 1, the top beam 1 is first placed in from the front and then lifted upward. The movable side rod 4 can first be docked in the installation groove 6. Through the setting of the fixing assembly 7, after the movable side rod 4 is docked, the threaded locking rod 702 is flipped over and the threaded locking rod 702 is flipped over to the inner wall of the fixing block 704. At this time, the butterfly nut 703 can be directly screwed so that the butterfly nut 703 is tightly attached to the surface of the fixing block 704, thus completing the fixation between the movable side rod 4 and the top beam 1. At this time, the connection between the movable side rod 4 and the top beam 1 can be completed without using any tools.

[0027] like Figure 4 As shown, the locking assembly 8 includes a threaded sleeve 801, the surface of the mounting column 2 is fixedly connected to the threaded sleeve 801, the inner wall of the threaded sleeve 801 is threadedly connected to the threaded fastening rod 802, and the threaded fastening rod 802 is threadedly connected to the mounting column 2; specifically, the locking assembly 8 is set up, the threaded sleeve 801 is used to connect the threaded fastening rod 802, and the threaded fastening rod 802 is used to lock and fix the movable side rod 4 after the movable side rod 4 moves in the mounting column 2.

[0028] like Figure 1 、 Figure 2As shown, the connecting component 9 includes a transmission connecting seat 901, the top surface of the top beam 1 and the bottom surface of the connecting member 11 are fixedly connected with the transmission connecting seat 901, the bottom surface of the top beam 1 and the top surface of the connecting member 11 are fixedly connected with a fixing seat 902, the surface of the fixing seat 902 is provided with a heald fixing plate 903, and the heald 10 is provided on the surface of the heald fixing plate 903; specifically, the setting of the connecting component 9 is that the transmission connecting seat 901 is used for connection with the loom equipment, the fixing seat 902 is used for connection with the heald fixing plate 903, and the heald fixing plate 903 is used for hanging connection of the heald 10.

[0030] Working principle: The heald frame used for the loom may need to be replaced when the height of the heald frame is adjusted significantly. A significant adjustment of the heald frame height will cause a significant change in the position of the heald eyelet of the heald, and the tension of the warp yarn will also change accordingly. If the original heald continues to be used, problems such as difficulty in threading the warp yarn, uneven tension, and increased fabric defects may occur. For example, if the height of the heald frame is adjusted by more than a few centimeters, the heald eyelet of the heald may not match the position of the warp yarn. At this time, it is necessary to replace the appropriate heald. If the height of the heald frame is only slightly adjusted, the heald generally does not need to be replaced. Because the heald usually has a certain degree of elasticity and adaptability, the heald can still work normally within a small range of height changes, and will not have a significant impact on the threading of the warp yarn and the production of the fabric. The threaded fastening rod 802 is screwed to the threaded sleeve 801, and the end of the threaded fastening rod 802 leaves the surface of the movable side rod 4, thereby releasing the locking fixation of the movable side rod 4. At this time, the movable side rod 4 can slide in the slot 301. The surface of the movable side rod 4 is embedded with a ball 5, and the ball 5 is limited in the ball groove 302. At this time, when the movable side rod 4 is moved, the ball 5 can roll, so that the movement of the movable side rod 4 in the slot 301 is smoother, thereby facilitating the movement process of the movable side rod 4. After the movement of the movable side rod 4 in the adjustment assembly 3 is completed, the threaded fastening rod 802 is screwed again, and the movable side rod 4 is locked and fixed by the threaded fastening rod 802. The setting of the connecting piece 11, After the connecting piece 11 is connected to the top surface of the mounting post 2, the ball bearing 5 is limited to prevent the movable side rod 4 from moving out of the adjusting assembly 3, that is, the distance between the top beam 1 and the bottom beam 12 is changed. At this time, the distance between the top beam 1 and the bottom beam 12 is changed according to the process requirements of the fabric, that is, the height adjustment of the heald frame is completed. The installation slot 6 and the fixing assembly 7 are set, and the bottom beam 12 can be fixedly connected to the mounting post 2 in advance without affecting the installation process of various components. At this time, when the movable side rod 4 is installed on the top beam 1, the top beam 1 is first put in from the front and then lifted upward. The movable side rod 4 can first be docked in the mounting slot 6. Through the setting of the fixing assembly 7, after the movable side rod 4 is docked, the threaded locking rod 702 is flipped, and the threaded locking rod 702 is flipped to the inner wall of the fixing block 704. At this time, the butterfly nut 703 can be directly screwed so that the butterfly nut 703 is close to the surface of the fixing block 704, that is, the fixation between the movable side rod 4 and the top beam 1 is completed.
