Description

Technical Field

[0001] The present invention relates to the technical field of rapier looms, in particular to an SJ758 rapier loom. Background Art

[0002] The rapier loom is the most widely used shuttleless loom. In addition to its high speed, high degree of automation, and high-efficiency production characteristics, its active weft insertion method offers strong adaptability to various yarn types. Furthermore, the rapier loom has a distinct advantage in weaving multi-color wefts. As shuttleless looms replace shuttle looms, the rapier loom will become the primary machine for producing woven fabrics.

[0003] On a rapier loom, the warp threads are usually passed through the heald frames. The warp threads are opened by raising or lowering the front and rear heald frames, and the rapier passes through the opening to manufacture the fabric.

[0004] When the heald frame is in the lower position, the warp threads are usually flush with the fabric. However, when the heald frame is in the upper position, it lifts the warp threads upward, creating an opening. During this lifting process, the warp threads are momentarily pulled upward, causing the entire warp to break. This excessive pulling force can easily cause the warp threads to break. Summary of the Invention

[0005] The purpose of the present invention is to provide an SJ758 rapier loom.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: The SJ758 rapier loom includes a frame, a rotatable transverse tube is provided on the rear side of the frame, a driving motor is provided on both sides of the frame, a rotating gear is provided on the rotating shaft of the driving motor, and an annular tooth meshing with the rotating gear is provided on the transverse tube; the transverse tube is hollow, a rotating tube body is passed through the transverse tube, a plurality of incisions connected to the interior are provided on the transverse tube, a plurality of shifting rods are provided on the rotating tube body, the shifting rods pass through the incisions, and two adjacent warp threads pass through the two sides of the shifting rods; electric push rods are provided at both ends of the frame, and the ends of the electric push rods abut against the two ends of the rotating tube body.

[0007] It is further configured that: rubber layers are provided on both sides of the shifting rod and on the inner walls on both sides of the incision.

[0008] It is further configured as follows: at least two annular rings are provided between the transverse tube and the rotating tube body, and the annular rings are made of plastic.

[0009] It is further configured that: there is a line between the clamping point of the warp line between the side wall of the lever and the inner wall of the cutout and the center of the horizontal tube, and the angle between the line and the vertical direction is .

[0010] It is further configured that: the release point of the warp thread between the side wall of the shifting rod and the inner wall of the cutout is located at the highest point in the vertical direction of the transverse tube.

[0011] In summary, the present invention has the following beneficial effects: Through the cooperation of the transverse tube and the rotating tube at the rear end of the SJ758 rapier loom, the radial stretch caused by the heald frame lifting can be compensated, thereby reducing the pulling force on the warp yarns and ensuring stability. In this structure, the stretch compensation of the warp yarns at the rear end is achieved by selectively moving the lever to the left or right. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further described in detail below with reference to the accompanying drawings.

[0015] The SJ758 rapier loom includes a frame, a transverse tube is provided at the rear end of the frame, a cylindrical hollow structure is provided in the transverse tube, and a cylindrical rotating tube body is provided in the cylindrical hollow structure. The upper edge of the transverse tube is provided with a plurality of transversely arranged incisions, which are connected to the internal hollow structure. The rotating tube body is also provided with a plurality of shifting rods, each corresponding to a incision. Rubber layers are provided on both sides of the inner wall of the incision, and rubber layers are also provided on both sides of the shifting rod. Two adjacent warp threads pass through the incision and are positioned on both sides by the shifting rods. The front and rear sides of the shifting rod abut against the front and rear inner walls of the incision, thereby limiting the shifting rod in the front and rear positions so that it can only move in the left and right positions.

[0016] Electric push rods are installed at both ends of the frame. The ends of the two electric push rods are inwardly pressed against the two ends of the rotating tube. When the electric push rods are activated, they can move the rotating tube to the left or right, thereby causing the lever on the rotating tube to press against the warp. The inner wall of the cutout on the other side also presses against the warp.

[0017] A driving motor is provided on the same side of both ends of the frame, a rotating gear is provided on the rotating shaft of the driving motor, and an annular gear meshing with the rotating gear is provided at both ends of the transverse tube.

[0018] When the transverse tube continues to rotate, the warp threads are resisted by the rubber layer, which can drive the radial threads to move, thereby compensating for the length lifted by the heald frame, reducing the pulling effect on the warp threads at this position, and thus reducing the occurrence of warp breakage problems.

[0019] A line is formed between the clamping point of the warp threads by the side wall of the shifting rod and the inner wall of the cutout and the center of the transverse tube, and the angle between the line and the vertical direction is X. Preferably, in order to maintain a more appropriate compensation position and ensure stability of the warp threads located below when being lifted by the heald frame, the release point of the warp threads by the side wall of the shifting rod and the inner wall of the cutout is located at the highest point in the vertical direction of the transverse tube.

[0020] The height of the heald frame when it is lifted is h, the horizontal distance between the heald frame eye and the front opening is a, the horizontal distance between the heald frame eye and the rear end transverse tube is b, the radius of the transverse tube is r1, and the height of the clamping point between the side wall of the lever and the inner wall of the cutout to the warp is r2. .

[0021] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.
