Description

Technical Field

[0001] The utility model relates to the field of rapier looms, in particular to a yarn mending hook used on rapier looms. Background Art

[0002] Rapier looms are a mainstream weaving machine, known for their high speed, stability, and wide adaptability. Among shuttleless looms, the rapier loom's weft insertion principle was first proposed. Initially, a single rapier was used, and later, a rapier loom with two rapiers for weft insertion was invented. When weaving fabric on a rapier loom, multiple bobbins are required to pay off the yarn. A mending hook, typically used on rapier looms, assists in placing the bobbins to prevent them from tipping over and causing knots.

[0003] After searching, the existing publication number CN206345970U is a yarn mending hook used for rapier looms; the utility model comprises a hook, a sleeve rod and a barb, the hook comprises a hook part and a supporting part, and the hook part is in an inverted "U" shape; one end of the sleeve rod is connected to the connection between the hook part and the supporting part, and the other end of the sleeve rod is connected to the barb; the hook is used to be hung on a fixed plate; when using the utility model, the cheese yarn is sleeved into the sleeve rod, and the barb blocks the bottom of the cheese yarn so that it will not slide out, and then the hook is hung on the fixed plate through the hook part, and the head of the cheese yarn on the top of the supporting part is balanced, so that it is not easy to shake due to imbalance when the yarn is pulled; the yarn on the cheese yarn is pulled onto the rapier loom, so that the yarn is stably pulled; the utility model has a simple structure, can be hung on the rapier loom through the hook, and is sleeved in the cheese yarn with the sleeve rod, and is easy to operate and has strong practicality.

[0004] When installing the yarn mending hook used on the rapier loom, the cheese yarn needs to be directly inserted into the sleeve rod, and the bottom of the cheese yarn needs to be limited by the hook at one end of the sleeve rod. However, the simple hook design is not convenient for the staff to replace and put the cheese yarn, and the right-angled hanging plate is directly hung on the fixed plate, which is not very firm and can only be adapted to fixed plates of fixed specifications.

[0005] Therefore, it is necessary to provide a new yarn mending hook that is applied on the rapier loom to solve the above-mentioned technical problems. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0022] Please refer to Figures 1 to 3 A yarn mending hook used on a rapier loom comprises: a hook plate 1, a back-hanging plate 2 is fixedly connected to the hook plate 1, a sleeve rod 3 is fixedly connected to the front side wall of the hook plate 1, and a stop plate 21 is provided between the back-hanging plate 2 and the hook plate 1; an automatic telescopic mechanism, the automatic telescopic mechanism comprises two side grooves 4, the two side grooves 4 are both provided on the rod wall of the sleeve rod 3, the two side grooves 4 are symmetrically arranged, a hook rod 41 is provided in the two side grooves 4, one end of the two hook rods 41 is provided with a pin shaft 42, the two pin shafts 42 are respectively rotatably connected to one end of the two side grooves 4, and a pulling component is provided between the two hook rods 41.

[0023] In the specific implementation process, Figure 2 and Figure 3 As shown, the pulling assembly includes a top slider 43, which is connected to the two hook rods 41 through two push rods 44. One end of the two push rods 44 is rotatably connected to the top slider 43, and the other ends of the two push rods 44 are rotatably connected to the side walls of the two hook rods 41. A spring 45 is installed and connected between the top slider 43 and one end wall of the cavity.

[0024] It should be noted that the push buckle 51 drives the thin rod 5 to slide, so that the thin rod 5 drives the top slider 43 at one end thereof to slide and retract, causing the spring 45 to undergo elastic deformation, and the top slider 43 drives the two push rods 44 to drive the two hook rods 41 to retract into the two side grooves 4, so that the used cheese yarn can be easily removed.

[0025] refer to Figure 2 and Figure 3As shown, a cavity is provided inside the sleeve rod 3, two through slots are provided between the two side slots 4 and the cavity, and the two push rods 44 are slidably connected to the two through slots respectively.

[0026] It should be noted that the two through slots can be used to limit the moving directions of the two push rods 44 .

[0027] refer to Figure 1 and Figure 3 As shown, a thin rod 5 is fixedly connected to the top slider 43 , and a push buckle 51 is fixedly connected to one end of the thin rod 5 .

[0028] It should be noted that the arrangement of the push buckle 51 facilitates the sliding of the thin rod 5 .

[0029] refer to Figure 3 As shown, a sliding opening is provided on the cavity wall at one end of the cavity, and the thin rod 5 is slidably connected to the sliding opening.

[0030] refer to Figure 1 and Figure 2 As shown, a slide rod 6 is slidably connected to the back hanging plate 2, a right-angle plate 7 is fixedly connected to the back hanging plate 2, a rotating shaft 71 is provided on the right-angle plate 7, one end of the rotating shaft 71 is rotatably connected to the slide rod 6, and the other end of the rotating shaft 71 is installed and connected to the turning handle 8.

[0031] It should be noted that the slide rod 6 slides relative to the back hanging plate 2, so that the slide rod 6 drives the support plate 21 at one end thereof to move, thereby conveniently adjusting the distance between the support plate 21 and the back hanging plate 2 to accommodate stable hanging of fixed plates of different specifications.

[0032] refer to Figure 1 and Figure 2 As shown, the rotating shaft 71 is a threaded rod, a threaded opening is provided on the right-angle plate 7, and the rotating shaft 71 is threadedly connected to the right-angle plate 7.

[0033] It should be noted that rotating the handle 8 drives the rotating shaft 71 to rotate, so that the sliding rod 6 slides relative to the back hanging plate 2.

[0034] The working principle of a yarn mending hook used on a rapier loom provided by the utility model is as follows: the cheese yarn is directly sleeved on the sleeve rod 3, so that the two hook rods 41 and the two pin shafts 42 rotate relative to the two side grooves 4 until they are retracted, and the two hook rods 41 drive the two push rods 44 to rotate accordingly, so that the top slider 43 simultaneously drives the thin rod 5 to slide, and the spring 45 undergoes elastic deformation until the cheese yarn is fully inserted, and the spring 45 restores the elastic deformation, so that the two hook rods 41 rotate in the opposite direction and reset to expand, so that the cheese yarn can be limited by using the two hook rods 41.

[0035] Pressing the push button 51 drives the thin rod 5 to slide, so that the thin rod 5 drives the top slider 43 at one end thereof to slide and retract, causing the spring 45 to elastically deform, and the top slider 43 drives the two push rods 44 to drive the two hook rods 41 to retract into the two side grooves 4, so that the used cheese yarn can be easily removed.

[0036] Hang the back hanging board 2 on the fixed board, turn the handle 8 to drive the rotating shaft 71 to rotate, so that the slide bar 6 slides relative to the back hanging board 2, and the distance between the back hanging board 21 and the back hanging board 2 can be easily adjusted to suit different specifications of fixed boards for stable hanging.

[0037] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
