Description
Technical Field
[0001] The utility model relates to the technical field of circular looms, in particular to a heddle tape assembly for a circular loom and a circular loom. Background Art
[0002] The shutdown of the circular loom due to the completion of weft or warp is a normal shutdown, while the shutdown due to warp breakage or weft breakage is an abnormal shutdown. The higher the shutdown probability, the worse the weaving performance of the circular loom. Compared with the two, the warp breakage probability is much higher than the weft breakage probability, and the higher the weaving speed, the higher the warp breakage probability. In addition, the circular looms currently in use in the market are generally not suitable for the weaving of thin filaments and thick filaments. All the above problems are related to the setting position of the heddles.
[0003] The centers of the heddle eyes of the existing inner and outer heddles are in the same radial direction of the circular loom. The inner and outer heddles are inclined at a certain angle in the same direction to avoid the warp threads and provide space for threading the warp threads. However, this structure has the following problems: the avoidance space is too small, and the warp threads passing through the heddle eyes of the inner heddles are likely to rub against the outer heddles and cause wear, or the warp threads passing through the heddle eyes of the outer heddles are likely to rub against the inner heddles and cause wear. In addition, since the inner and outer heddles are inclined at a certain angle, the inner and outer heddles need to be twisted during processing, and the accuracy requirement for twisting is relatively high. Based on this problem, the heddle tape assembly is improved. Summary of the Utility Model

[0023] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments and the attached drawings. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without making creative efforts all fall within the protection scope of the present utility model.
[0024] The following describes the specific embodiments of the present utility model with reference to the attached drawings.
[0025] Such as Figure 1-8A circular loom heddle belt assembly and a circular loom as shown, comprising an upper heddle belt 1, a lower heddle belt 2, outer heddles 3 and inner heddles 4. The upper heddle belt 1 is installed on an upper roller 5, and the lower heddle belt 2 is installed on a lower roller 6. The upper roller 5 and the lower roller 6 are respectively arranged on a connecting seat 13. The two ends of the inner heddle 4 are respectively connected to the inner ends of the upper heddle belt 1 and the lower heddle belt 2, and the two ends of the outer heddle 3 are respectively connected to the outer ends of the upper heddle belt 1 and the lower heddle belt 2. Folding parts 17 are respectively arranged at the inner and outer ends of the upper heddle belt 1 and the lower heddle belt 2, and through holes 20 are arranged on the side surfaces of the folding parts 17. A plurality of first wire hanging grooves 9 are arranged at equal intervals below the folding part 17 at the inner end of the upper heddle belt 1, and a plurality of second wire hanging grooves 10 are arranged at equal intervals below the folding part 17 at the outer end. The structures of the folding parts 17 at the inner and outer ends of the lower heddle belt 2 are the same as those of the upper heddle belt 1. The first wire hanging grooves 9 and the second wire hanging grooves 10 are respectively communicated with their corresponding through holes 20, and the first wire hanging grooves 9 and the second wire hanging grooves 10 are staggered with each other in the warp thread feeding direction. Hanging rings 11 are respectively arranged at the two ends of the inner heddle 4 and the outer heddle 3. In this embodiment, the hanging rings 11 are in a ring shape. A hanging rod 12 for passing through the through hole 20 to connect the hanging rings 11 in a plurality of wire hanging grooves together is arranged on the side surface of the folding part 17; the heddle eyes 7 of the inner heddle 4 and the heddle eyes 7 of the outer heddle 3 are staggered with each other in the warp thread feeding direction, so that the heddle eyes 7 of the outer heddle 3 are correspondingly located between two adjacent inner heddles 4 or the heddle eyes 7 of the inner heddle 4 are correspondingly located between two adjacent outer heddles 3. The heddle eyes 7 of the inner heddle 4 are perpendicular to the warp thread feeding direction, and the heddle eyes 7 of the outer heddle 3 are perpendicular to the warp thread feeding direction, reducing the installation difficulty of the heddles and eliminating the need to consider the deflection angle.
[0026] During the warp thread opening process, the upper roller 5 of the upper heddle belt 1 rotates forward and backward repeatedly, causing the upper heddle belt 1 to move repeatedly. At the same time, the lower roller 6 of the lower heddle belt 2 rotates forward and backward repeatedly, causing the lower heddle belt 2 to move repeatedly. As a result, the outer heddles 3 and the inner heddles 4 move up and down reciprocally. The heddle eyes 7 of the inner heddle 4 and the heddle eyes 7 of the outer heddle 3 are staggered with each other in the warp thread feeding direction, so that the heddle eyes 7 of the outer heddle 3 are correspondingly located between two adjacent inner heddles 4 or the heddle eyes 7 of the inner heddle 4 are correspondingly located between two adjacent outer heddles 3. The heddle eyes 7 of the inner heddle 4 are perpendicular to the warp thread feeding direction, and the heddle eyes 7 of the outer heddle 3 are perpendicular to the warp thread feeding direction. In this embodiment, the heddle eyes 7 are preferably rectangular holes or round holes. As Figure 4 shown, the heddle eyes 7 of the inner heddle 4 are located on an inner side plane formed by a track line 21 where the inner heddle 4 is arranged, making the warp thread feeding direction perpendicular to each heddle eye 7. The same applies to the outer heddle 3. The center distance between two adjacent heddle eyes 7 is 8.1 mm - 8.5 mm, and preferably 8.4 mm in this embodiment.
[0027] On the left or right side of the inner end of the upper heddle tape 1, there is a wire hanging notch 8 corresponding to the first wire hanging groove 9. The folding part 17 at the inner end of the upper heddle tape 1 is arranged with the first wire hanging grooves 9 at equal intervals starting from the wire hanging notch 8; the wire hanging notch 8 at the outer end of the upper heddle tape 1 is opposite to the wire hanging notch 8 at the inner end, and the folding part 17 at the outer end of the upper heddle tape 1 is arranged with the second wire hanging grooves 10 at equal intervals starting from the wire hanging notch 8; the structures of the inner end and the outer end of the lower heddle tape 2 are the same as those of the inner end and the outer end of the upper heddle tape 1. In this embodiment, the wire hanging notch 8 is arranged on the left side of the inner end of the upper heddle tape 1, and the first wire hanging grooves 9 are arranged from left to right on the heddle tape starting from the wire hanging notch 8, while on the outer end of the upper heddle tape 1, the wire hanging notch 8 is arranged on the right end, and the second wire hanging grooves 10 are arranged from right to left on the upper heddle tape 1 starting from the wire hanging notch 8, so as to realize the dislocation of the inner and outer heddle eyes 7. The same applies to the lower heddle tape 2.
[0028] The heddle eyes 7 of the inner heddle wires 4 and the heddle eyes 7 of the outer heddle wires 3 are relatively staggered, which can provide more space for the warp threads to pass through, reduce the degree of wear of the warp threads passing through the heddle eyes 7 of the outer heddle wires 3 and the inner heddle wires 4, and reduce the degree of scraping wear of the warp threads passing through the heddle eyes 7 of the inner heddle wires 4 and the outer heddle wires 3. Thus, during the process of the warp threads' shedding, the degree of wear between the warp threads and the heddle wires is reduced, the number of warp breaks is greatly reduced, and the weaving efficiency and quality of the circular loom are ensured.
[0029] The hanging rod 12 includes a rod portion 18 and a blocking portion 19 provided at the end of the rod portion 18. The blocking portion 19 is limited outside the through hole 20. The rod portion 18 is inserted into the through hole 20 and one end of the rod portion 18 opposite to the blocking portion 19 extends to the outside of the other end of the through hole 20. A detachable plug (not shown in the figure) or a through hole is provided at one end of the rod portion 18 opposite to the blocking portion 19. If a plug is used, methods such as threaded connection or plug connection are adopted. If a through hole is used, a pin is inserted.
[0030] The lower heddle tape 2 includes a first heddle tape 14, a second heddle tape 15, and a connecting member 16 for connecting the two. The first heddle tape 14 is located above the second heddle tape 15 and the first heddle tape 14 and the inner heddle wires 4 are on the same side. Part of the second heddle tape 15 is on one side of the inner heddle wires 4 and the other part is on one side of the outer heddle wires 3. The inner side of the connecting member 16 is connected to the swing arm assembly. The swing arm assembly (not shown in the figure) is an important part of the circular loom. It includes a mounting seat and a swing arm. There is a shaft hole on the swing arm, and a bushing is provided in the shaft hole. A shaft body is fixedly provided on the mounting seat, and the shaft body passes through the bushing. A bearing is provided between the shaft body and the bushing. A guide groove mechanism is provided at one end of the swing arm, and a swing rod is hinged at the other end. The swing rod is used to connect the heddle tape. A guide rail is provided on the circular loom frame, and the swing arm is driven to swing through the cooperation of the guide rail and the guide groove mechanism. The swing arm assembly has been disclosed in the previous application and is prior art, so it will not be specifically described here.
[0031] Taking the main shaft of the circular loom as the center of the circle, since the upper roller 5 of the upper heddle tape 1 and the lower roller 6 of the lower heddle tape 2 are on circles with the same diameter, it can be imagined that the inner ends of the upper heddle tape 1 and the lower heddle tape 2 are basically on the same circle, the outer ends of the upper heddle tape 1 and the lower heddle tape 2 are also basically on the same circle, all the inner heddle wires 4 are basically on the same circle, and all the outer heddle wires 3 are basically on the same circle. Therefore, the diameter of the circle where the inner heddle wires 4 are located is smaller than the diameter of the circle where the outer heddle wires 3 are located, and the positions of the outer heddle wires 3 and the inner heddle wires 4 are determined by the first wire hanging groove 9 and the second wire hanging groove 10. So, the first wire hanging groove 9 and the second wire hanging groove 10 are designed to be relatively staggered, making the heddle eyes 7 of the inner heddle wires 4 and the heddle eyes 7 of the outer heddle wires 3 staggered.
[0032] The structure of the above-mentioned heddle tape assembly is applied to a circular loom.
[0033] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present invention and do not limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
