Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a siro spinning roving frame. Background Art

[0002] With the substantial increase in the production capacity of sirospinning and compact sirospinning products, the roving frames currently used for sirospinning transformation and production on the market are limited by the space and structure of traditional roving frames. Almost all of them have the following problems: First, they cannot adapt to large-capacity roving. During production, the roving package capacity can only be sacrificed to meet production needs, resulting in increased workload for yarn change and high labor intensity for operators; second, the yarn guide rod has an unreasonable yarn guide angle, which results in high yarn guide tension, causing unexpected elongation of the roving during unwinding, and the unwinding between spindles is not synchronized and has large differences. In severe cases, the yarn guide ends are broken. This... This will cause large differences in the unwinding lengths of the roving, affecting the planning of the yarn changers, and will cause a large amount of roving ends to be consumed for collective yarn changing. At the same time, the roving unwinding breakage will seriously affect the work efficiency of the spinning workers; thirdly, due to the small distance between the roving and the yarn guide rod, when the roving is unwound to the upper or lower part, not only will the yarn drawing force be concentrated and increased, but the roving will also cause serious unexpected elongation. At the same time, the unwound roving strips will roll on the surface of the roving, which will cause serious slippage and adhesion breakages for some chemical fiber varieties with smaller twist, increasing the labor intensity of workers and affecting product quality.

[0003] Patent No. CN207727217U discloses a siro spinning yarn guide device, which has eight rows of spindles on the roving frame. Through the staggered setting of the front and rear rows of spindles and the reasonable setting of the yarn guide rods, the phenomenon of roving hitting each other is reduced, the slivers and accidental drafting are reduced, the hairiness is reduced, and the work efficiency is improved. However, the single-row spindles are arranged side by side, and when the space occupied by the roving frame is limited, it is still impossible to use a large-capacity roving roll; a set of yarn guide rods needs to be set between every two spindles, resulting in a complex roving frame structure, complex operation, and low efficiency.

[0004] Therefore, there is an urgent need for a new type of siro spinning roving frame that can accommodate large-capacity roving, has a reasonable yarn guide angle, and has a suitable distance between the roving and the yarn guide rod. Summary of the invention

[0005] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a new single-layer eight-row siro spinning roving frame, which can adapt to large-capacity roving, reduce the workload of yarn changing, have a reasonable yarn introduction angle, a small and stable yarn introduction tension, no entanglement between rovings, small accidental elongation of rovings, small roving unwinding tension, good unwinding tension uniformity, improve the roving unwinding synchronization and consistency, reduce the labor intensity of value-added workers, have high production efficiency and good product quality.

[0009] Furthermore, the installation height of the first yarn guide is 30% to 40% of the length of the roving tube on the hanging spindle.

[0010] Furthermore, a yarn guide cross bar is installed at the bottom of the column, and a third yarn guide member is installed at the end of the yarn guide cross bar to guide the roving drawn out from the second yarn guide member to the subsequent process.

DETAILED DESCRIPTION

[0021] See also Figure 1~Figure 4 The utility model relates to a siro spinning roving frame, comprising a column 1, a crossbeam 3 installed on the column 1, and four hanging spindles 2 are respectively arranged on the crossbeam 3 on both sides of the column 1. The four hanging spindles 2 are arranged on the crossbeam 3 in a front-to-back staggered manner. The four hanging spindles 2 are arranged in groups of two, and the two groups of hanging spindles 2 are symmetrically arranged. Figure 2 ; The four hanging spindles 2 are staggered. When the occupied space remains unchanged, the space distance between adjacent hanging spindles 2 is enlarged, which can accommodate roving tubes with larger capacity. In this embodiment, the roving diameter can be expanded to 120-128 cm, thereby reducing the frequency of changing roving and the labor intensity of the value sewing workers;

[0022] A set of yarn guide device is installed on the crossbeam 3 located between the two groups of hanging spindles 2 to synchronously lead out the rovings on the four hanging spindles 2; the yarn guide device comprises a yarn guide vertical rod 7 installed at the bottom of the crossbeam 3, a first yarn guide member 4 and a second yarn guide member 5 sequentially mounted on the yarn guide vertical rod 7; the installation height of the first yarn guide member 4 is 30% to 40% of the length of the roving tube on the hanging spindle 2, with the lower end of the roving tube as the reference, see Figure 3 The second yarn guide 5 is located at the lower end of the yarn guide vertical rod 7; the roving is drawn out from the roving tube on the hanging spindle 2, and after being guided by the first yarn guide 4, it enters the second yarn guide 5 for secondary guidance;

[0023] The four hanging spindles 2 are staggered, and the distances between the first yarn guide 4 and the four yarn guide tubes are very small. Therefore, the rovings on the four hanging spindles 2 can be synchronously led out, the yarn leading is clear, and there is no entanglement between the rovings, which reduces the accumulation of hairiness at the bell mouth and reduces the number of cleaning times by the lathe operator. Each hanging spindle 2 surrounds the first yarn guide 4, and the yarn leading angle is more reasonable and smooth, so that the yarn leading tension is small and stable, the unexpected elongation is small, and the synchronization and consistency of the roving unwinding are improved, so that the planning of the roving replacement is better, and the consumption of the roving heads can be significantly reduced for the collective roving replacement, which not only greatly reduces the roving unwinding breakage, reduces the labor intensity of the workers, but also reduces and improves the generation of unexpected elongation, and improves the product quality level;

[0024] A yarn guide cross bar 8 is installed at the bottom of the column 1, and a third yarn guide 6 is installed at the end of the yarn guide cross bar 8 to guide the roving drawn from the second yarn guide 5 to the subsequent process;

[0025] A roving tube lifting mechanism is provided at the end of the crossbeam 3, comprising a guide rail 10 installed on the crossbeam 3 through a connecting plate 9, and a lifting portion 12 slidably set on the guide rail 10 through a roller 11; the roving tube is lifted at the lower part of the lifting portion 12, which further facilitates the transportation of the roving tube when changing yarn, improves production efficiency, and reduces the labor intensity of workers.

[0026] In addition: It should be noted that the above specific implementation is only an optimization scheme of this patent. Any changes or improvements made by technicians in this field based on the above concept are within the scope of protection of this patent.
