Description

Technical Field

[0001] This utility model belongs to the technical field of weaving machine equipment, specifically relating to a limiting device for the weft insertion mechanism of a weaving machine. Background Technology

[0002] Guangduan originated in Guangdong Province, my country. Its weaving technique involves colorful jacquard patterns and is a high-grade silk fabric with heavy warp and weft. The fabric's pattern design, color scheme, and artistic expression have typical Lingnan characteristics.

[0003] Currently, the production of Guangduan (Guangdong satin) is carried out using traditional looms. The earliest loom was a floor-standing loom (called a waist loom). The method of use involved using the feet to pedal the warp rollers, the right hand holding a weft-beating knife to tighten the weft threads, and the left hand in the action of feeding the weft. This foot-operated waist loom had no frame; one end of the fabric roll was tied to the waist, and the feet pedaled the other end of the warp roller to tension the fabric. The warp yarns were divided into two layers according to odd and even numbers using a warp divider, and the warp yarns were lifted by a heald rod to form the shed. Weft was fed in using a bobbin and beaten in with a weft-beating knife. The most important achievement of waist loom weaving was the adoption of these three components: the heald rod, the warp divider, and the weft-beating knife. Although this loom appeared simple, it already possessed three-directional movement: opening the shed vertically, feeding the weft horizontally, and tightening the weft back and forth. It is the ancestor of the warp feeding mechanism in modern looms.

[0004] Currently, the aforementioned traditional looms are still used in modern society and are being preserved as part of traditional culture. During the warp feeding process, it is necessary to maintain a certain tension on the warp yarns. The connection between the weft-beating mechanism and the frame of the current loom is relatively simple, such as... Figure 1 The weft insertion mechanism includes a reed frame, weft insertion connecting rope, striking rod, upright rod, and upright base. When the reed frame moves, it drives the striking rod to move. Currently, there is no limit structure for the movement stroke of the striking rod, which can easily cause excessive stroke and affect the overall production. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a limiting device for the beat-up mechanism of a weaving machine.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A limiting device for the weft-beating mechanism of a loom, the weft-beating mechanism including a reed frame, a weft-beating connecting rope, a striking rod, a support rod, and a support base, the weft-beating connecting rope being connected to the frame of the loom and one end of the reed frame, the striking rod being connected to the other end of the reed frame and the support rod, the support base being disposed on the frame of the loom, and the support rod being hinged to the support base;

Detailed Implementation

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0026] Example:

[0027] like Figure 1-3As shown, this embodiment provides a limiting device for the weft insertion mechanism of a loom. The weft insertion mechanism includes a reed frame 2, a weft insertion connecting rope 3, a striking rod 4, a support rod 5, and a support base 6. The weft insertion connecting rope 3 is connected to one end of the loom frame 1 and the reed frame 2, respectively. The striking rod 4 is connected to the other end of the reed frame 2 and the support rod 5, respectively. The support base 6 is located on the loom frame 1, and the support rod 5 is hinged to the support base 6.

[0028] The limiting device includes a limiting seat 7, a limiting mounting plate 8, a guide wheel 9, a limiting rope 10, an elastic element 11, and a limiting element 12. The limiting seat 7 is located on the impact rod 4, the limiting mounting plate 8 is located on the frame 1 of the weaving machine, there are multiple guide wheels 9 and they are located on the limiting mounting plate 8. The guide wheels 9 are provided with guide grooves 18, the limiting rope 10 cooperates with the guide grooves 18, one end of the limiting rope 10 is provided with a handle 17, and the other end is connected to the elastic element 11. The limiting element 12 is connected to the elastic element 11.

[0029] The limiting seat 7 is provided with several limiting grooves 13 along the length of the impact rod 4. The limiting rope 10 can move relative to the guide wheel 9 and can make the limiting member 12 cooperate with a limiting groove 13.

[0030] A stop bar 14 is provided on the frame 1 of the loom at the position corresponding to the limit seat 7.

[0031] The limiting device of the weft insertion mechanism in this embodiment limits the displacement stroke of the striking rod 4. According to the specific structure of the weft insertion mechanism, when the operator pulls the reed frame 2, the striking rod 4 moves relative to the frame 1 of the loom. Therefore, the limiting seat 7 is located on the striking rod 4, and the limiting mounting plate 8 is positioned above the limiting seat 7. Under the gravity of the limiting member 12, the limiting member 12 moves towards the limiting seat 7 by default. When the limiting rope 10 can be moved relative to the guide wheel 9 by adjustment, the limiting member 12 cooperates with the guide groove 18 and forms an integral structure with the limiting seat 7. When the striking rod 4 moves again, the stop bar can contact the limiting member 12 to achieve a limiting effect, thereby limiting the displacement stroke of the striking rod 4 and ensuring the stability of the overall structure operation. Furthermore, the structure of the elastic member 11 acts as a buffer when the limiting member 12 cooperates with a limiting groove 13.

[0032] In this embodiment, the limiting mounting plate 8 is provided with connecting posts 15 corresponding to the number of guide wheel components 9, and the guide wheel components 9 are rotatably engaged with the connecting posts 15.

[0033] Specifically, the guide groove 18 is an annular groove structure.

[0034] In the above structure, when the limiting rope 10 can move relative to the guide wheel 9, the guide wheel 9 can rotate relative to the connecting column 15, so that the limiting rope 10 can move smoothly relative to the guide wheel 9.

[0035] In this embodiment, the arrangement structure of the guide wheel 9 is as follows: several connecting posts 15 form a row of connecting posts 15 groups, and the end face of the limiting mounting plate is provided with two rows of parallel connecting post groups. The connecting posts 15 of one connecting post group are located below the space between the two connecting posts 15 of the other connecting post group.

[0036] In this embodiment, the weft insertion connecting rope 3 can be sequentially engaged with the guide grooves 18 of the upper and lower guide wheel components 9 to ensure the stability of the engagement between the weft insertion connecting rope 3 and the guide wheel component 9. In this way, when the limiting component 12 moves with the limiting seat 7, it can prevent the limiting component 12 from disengaging from the limiting seat 7 due to the shaking of the weft insertion connecting rope 3.

[0037] In this embodiment, the limiting groove 13 has a V-shaped cross-section, and several limiting grooves 13 form a sawtooth structure on the limiting seat 7. The end of the limiting member 12 that cooperates with the limiting groove 13 is pointed. The above structure can better enable the limiting member 12 to cooperate with the limiting groove 13.

[0038] Specifically, the frame 1 of the loom is also equipped with a limiting ring 16, through which the limiting rope 10 passes. The opening size of the limiting ring 16 is smaller than the cross-sectional size of the handle part 17. Because the limiting member 12 moves towards the limiting seat 7 by default under the gravity of the limiting member 12, the limiting ring 16 abuts against the handle part 17, which can prevent the limiting rope 10 from completely passing through the guide wheel member 9 and separating from the guide wheel member 9, thus rendering the limiting function ineffective.

[0039] Meanwhile, multiple limiting mounting plates 8 can be provided on the frame 1 of the loom in this embodiment to guide the position of the limiting rope 10 relative to the frame 1, so that the handle 17 connected to one end of the limiting rope 10 can be in a position close to the operator, making it convenient for the operator to operate the handle 17.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
