Technical Field

[0001] The utility model relates to the technical field of looms, in particular to a yarn breaking device for looms. Background Art

[0002] A loom, also called a spinning machine or a weaving machine, is a machine used to weave fibers or yarns into cloth. It is usually composed of a frame, a warp shaft, a weft shaft, a heald frame, a needle and other parts. The working principle of a loom is to interweave the warp and weft yarns together to form cloth through the movement of the warp shaft and the weft shaft. There are many types of looms, which can be divided into manual looms, automatic looms, knitting machines, shuttle looms, etc. according to their different uses and working principles. When an existing loom breaks yarn, due to the elasticity of the gauze, the yarn-breaking blade will press down the fabric and the gauze cannot be cut off. It is necessary to manually break the yarn again, which affects the speed of yarn breaking in the fabric and reduces production efficiency.

[0003] Therefore, the utility model proposes a yarn breaking device for a loom. Utility Model Content

[0025] Example

[0026] like Figure 1 to Figure 2As shown in the figure, the yarn breaking device of the loom proposed by the utility model includes a support block 1, and further includes: two cylinders 2 fixedly installed inside the support block 1, and the cylinders 2 are driven by an air compressor; a mounting plate 3 fixedly arranged at the output end of the cylinder 2, a yarn breaking cutter 4 for cutting the woven fabric is fixedly arranged on the bottom surface of the mounting plate 3, and the yarn breaking cutter 4 is connected to the mounting plate 3 by bolts, which is convenient for replacing the cutting tool and can automatically cut the woven fabric to improve the cutting efficiency; and, two groups of connecting rods 5 fixedly arranged at the bottom surface of the support block 1, the lower ends of the connecting rods 5 are fixedly connected with a support plate 6, a cutting groove 7 is formed on the upper surface of the support plate 6, and the cutting groove 7 is located directly below the yarn breaking cutter 4, which can avoid the position of the yarn breaking cutter 4 so that it can cut the woven fabric completely; a linkage rod 8 hinged on both sides of the mounting plate 3, and a pressing assembly 9 for tightly pressing the woven fabric is hinged at the lower end of the linkage rod 8, which can tightly press the woven fabric so that the woven fabric will not be displaced and has too much elasticity, improving the efficiency and quality of yarn breaking.

[0027] As Figure 3 shown, the pressing assembly 9 includes a pressing plate 91 hinged at the lower end of the linkage rod 8, support frames 92 are respectively fixedly arranged on both sides of the pressing plate 91, and the support frames 92 are arranged in a "U" shape structure, which has good stability. A guiding through groove 93 is formed on one side of the support frame 92, a guiding block 94 is slidably arranged inside the guiding through groove 93, which can limit the guiding block 94. One end of the guiding block 94 is fixedly connected with a fixing rod 95, which can stably support the pressing plate 91 so that it presses the woven fabric more stably. The other end of the fixing rod 95 is fixedly connected with a connecting block 96, a guide rod 97 is fixedly connected to the outer wall of the connecting block 96, and one end of the guide rod 97 passes through the pressing plate 91 movably, which can guide the connecting block 96 to make its movement more stable. A spring 98 is sleeved on the outer wall of the guide rod 97, one end of the spring 98 is fixedly connected with the pressing plate 91, and the other end of the spring 98 is fixedly connected with the connecting block 96, which can buffer the pressing plate 91 to avoid excessive pressure and pressing the woven fabric to both sides and damaging it.

[0028] As Figure 1 and Figure 2 shown, a sliding groove 10 is formed on the support block 1, a group of sliding rods 11 are slidably arranged inside the sliding groove 10, which can guide the sliding rods 11 to make their movement more stable. The lower end of the sliding rod 11 is fixedly connected with a clamping block 12, and the clamping block 12 is arranged in a "冂" shape structure, which is convenient for clamping on the outer frame of the loom. A first adjusting bolt 13 is threadedly penetrated through one side of the clamping block 12, and one end of the first adjusting bolt 13 is rotatably connected with a first limiting block 14, which is convenient for installing woven fabrics of different sizes and models and improving the applicability.

[0029] Furthermore, mounting frames 15 are respectively provided on both sides of the upper surface of the support block 1, and the mounting frames 15 pass through the interior of the slide groove 10. A second adjusting bolt 16 is threadedly penetrated through the upper surface of the mounting frame 15, and the lower end of the second adjusting bolt 16 is rotatably connected to a second limit block 17, which can limit the slide rod 11, thereby facilitating the adjustment of the position.

[0030] Secondly, a rubber gasket 18 is provided on the bottom surface of the mounting plate 3, which can increase the friction between the supporting plate 6 and the fabric, making the pressing more stable.

[0031] Furthermore, the slide bar 11 is arranged in an "L"-shaped structure, so as to stably support the yarn breaking device.

[0032] The working principle of this embodiment is as follows: when installing the yarn breaking device, first manually rotate the second adjusting bolt 16 according to the width adjustment of the loom, so that the second adjusting bolt 16 drives the mounting frame 15 to move vertically upward on the first limiting block 14, and then manually pull the slide bar 11 to both sides, and the slide bar 11 moves horizontally in the slide slot 10, so that the clamping block 12 can be clamped on both sides of the loom frame. Then rotate the second adjusting bolt 16 in the opposite direction, so that the second adjusting bolt 16 drives the mounting frame 15 to move vertically downward in the first limiting block 14, and the slide bar 11 is limited.

[0033] Furthermore, by manually rotating the first adjusting bolt 13, the first adjusting bolt 13 drives the first limiting block 14 at one end to move, so that the first limiting block 14 is closely attached to the outer wall of the loom, thereby limiting the position of the first limiting block 14.

[0034] After the yarn breaking device is installed, the cloth is passed between the yarn breaking tool 4 and the support plate 6. When the yarn needs to be broken, the output end of the cylinder 2 drives the mounting plate 3 to move vertically downward, and the mounting plate 3 drives the pressing assembly 9 to move vertically downward through the connecting rod 8, so that the pressing plate 91 presses the cloth tightly. When the cloth is pressed tightly, it is resisted by the support plate 6, so that the guide block 94 slides horizontally in the pressing plate 91, and the guide block 94 drives the connecting block 96 to move horizontally, and the connecting block 96 drives the guide rod 97 to slide horizontally on the pressing plate 91, and the connecting block 96 pushes the spring 98 to contract, thereby avoiding excessive pressure to tear and damage the cloth.

[0035] Finally, after the gauze is compressed, the yarn-breaking cutter 4 cuts vertically downward to cut off the compressed gauze, which can reduce the movement and deformation of the gauze during the cutting process, thereby improving the cutting accuracy and cutting efficiency.

[0036] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
