Description

Technical Field

[0001] The utility model relates to the technical field of jacquard machine accessories, in particular to a harness-transforming heald rod for a jacquard machine. Background Art

[0002] The heald rod is an accessory part of the loom, usually made of thin wire, steel wire or steel sheet. There is a small opening in the center, called the heald eye, which allows the warp yarn to pass through. During the weaving process, each heald rod controls the movement of a warp yarn separately, driving them up and down to create a shed for the weft yarn to pass through. This mechanism effectively facilitates the insertion of the weft yarn and ensures the smooth progress of the weaving process.

[0003] When the heald rod is installed on the jacquard machine, it is usually installed on the heald frame, specifically on the crossbeam of the heald frame, and the heald ear of the heald rod is connected to the crossbeam. The specifications of the heald frames of various jacquard machines are different, and the specifications of the heald ears of the required heald rods are also different. There are open heald ears, closed heald ears, and heald ears with adjustable sizes formed by iron wire loops. Even the heald ears formed by iron wire loops, although they can be adjusted in size, are made of twisted iron wires, so their structural strength is poor, and they will also be deformed during the threading process, which will result in a short life of the structure.

[0004] Therefore, a harness-transformed heald rod for a jacquard machine is proposed to solve or alleviate the above problems. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] A harness-reformed heald rod for a jacquard machine, such as Figure 1 and 2 As shown, the heald loop 4 is C-shaped, the eye 1, and the rod body 3 fixedly connected to both ends thereof, the heald loop 4 is fixedly connected to the end of the rod body 3 away from the eye 1, and the eye 1 is provided with a heald eye 2. In fact, the heald loop 4, the rod body 3 and the eye 1 are in an integrally formed structure, and the inner circle of the heald loop 4 is provided with a plurality of anti-slip grooves 15, the heald loop 4 has an open groove 9, and an adjustment component is provided at the open groove 9. The adjustment component can adjust the size of the available space in the heald loop 4. The available space in the heald loop 4 is divided into an open type, a semi-open type, and a closed type.

[0025] The specific adjustment of the available space in the heald loop 4 to form an open, semi-open, and closed structure is as follows:

[0026] like Figure 3-6 As shown, the heald eye 4 on one side of the open groove 9 is provided with a through groove 5 connecting its inner ring with the outside, the heald eye 4 on the other side of the open groove 9 is provided with a groove 7 connecting its inner ring, and the inner ring of the heald eye 4 is provided with a circular arc groove 10, and the adjustment component includes a connecting rod 8 rotatably connected in the through groove 5, and one end of the connecting rod 8 away from the rotation axis can be detachably connected to the groove bottom of the through groove 5, the circular arc groove 10, and the groove 7 respectively. When the connecting rod 8 is detachably connected to the groove bottom of the through groove 5, an open type is formed in the heald eye 4, when the connecting rod 8 is detachably connected to the circular arc groove 10, a semi-open type is formed in the heald eye 4, and when the connecting rod 8 is detachably connected to the groove 7, a closed type is formed in the heald eye 4.

[0027] The end of the through groove 5 close to the open groove 9 is fixedly connected with the rotating shaft 6, the connecting rod 8 is provided with a rotating groove for the rotating shaft 6 to pass through, the outer ring of the connecting rod 8 is provided with a plurality of anti-slip grooves 16, and the end of the connecting rod 8 away from its rotation axis can be detachably connected with the groove bottom of the through groove 5, the arc groove 10, and the groove 7 respectively. The specific structure is: the inner walls of the through groove 5, the groove 7, and the arc groove 10 are all provided with concave holes 12, and the number of the concave holes 12 located in the through groove 5 and the groove 7 is several groups, the connecting rod 8 is provided with a connecting hole, the concave hole 12 is fixedly connected with a spring 13, and the end of the spring 13 away from the groove bottom of the concave hole 12 is fixedly connected with a ball 14, and the ball 14 can be embedded in the connecting hole.

[0028] When people need to assemble the heald rod, they only need to use naked eyes to judge the thickness of the upper and lower beams in the heald frame of the jacquard machine to determine whether the available space of the heald ear 4 in the heald rod needs to be adjusted to an open type, a semi-open type, or a closed type.

[0029] If it is necessary to keep the available space of the heald ear 4 in the heald rod open, then people only need to manually apply a certain force to the peripheral wall of the connecting rod 8 so that it obtains a force in the circumferential rotation direction. In this process, the hemispherical connecting hole will contact the ball 14 through its spherical surface, and generate a force in the depth direction of its recessed hole 12, so that the ball 14 can compress the spring 13, and finally the ball 14 can also completely enter the recessed hole 12, so that the ball 14 and the connecting hole will no longer hinder the deflection process of the connecting rod 8. As a result, the connecting rod 8 can be deflected until it enters the through groove 5, and the edge of the connecting rod 8 will contact the spherical surface of the ball 14 in the recessed hole 12 of the through groove 5, so that the ball 14 generates a force in the depth direction of the recessed hole 12, so that the ball 1 4 can also compress the spring 13, so that the ball 14 enters the concave hole 12, until the concave hole 12 corresponds to the connecting hole on the connecting rod 8, the spring 13 releases the elastic potential energy, so that the spring 13 presses the ball 14 to be embedded in the connecting hole of the connecting rod 8, thereby completing the detachable connection of the connecting rod 8 in the through groove 5. At this time, the connecting rod 8 no longer blocks the available space in the heald ear 4, thereby forming an open type. In the process of use, since there are anti-skid grooves 15 on the inner circumferential wall of the heald ear 4, and a plurality of anti-skid grooves 2 16 are provided on the outer ring of the connecting rod 8, when the heald ear 4 is connected to the crossbeam of the heald frame, there can be a large friction force, and it is not easy to slip. At the same time, since the heald rod is in a sheet shape and made of stainless steel, it has a greater structural strength than the heald rod twisted into iron wire, and it is not easy to deform.

[0030] At the same time, when the connecting rod 8 is detachably connected to the arc groove 10, half of the available space in the heald eye 4 remains, presenting a semi-open type; and when the connecting rod 8 is detachably connected to the groove 7, the connecting rod 8 closes the open groove 9, so that the entire heald eye 4 is closed, thereby adapting to the crossbeams in different heald frames.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
