Description

Technical Field

[0001] The utility model relates to the technical field of cotton yarn production, in particular to a spinning machine used for cotton yarn production. Background Art

[0002] Cotton yarn is the yarn made from cotton fiber through spinning process, and is called cotton thread after plying. According to different spinning processes, it can be divided into carded yarn and combed yarn; carded yarn: the yarn spun from cotton fiber through ordinary spinning system; combed yarn: the yarn spun from cotton fiber through combed spinning system. Combed yarn uses high-quality raw materials, and the fibers in the yarn are straight and parallel, with few knots, good luster, uniform yarn and high strength. This type of cotton yarn is mostly used to weave high-end fabrics.

[0003] When the spinning machine is working normally, during the process of cotton yarn being processed into yarn by the spinning machine, the transmission mechanism may fluctuate in the transmission process due to disrepair during long-term operation. That is, the transmission mechanism fails to produce the transmission effect normally at a certain moment, so that the yarn may be delayed when it is wrapped around the outside of the yarn collection drum, resulting in loose yarn winding, which may cause the yarn to entangle with itself and knot, affecting the normal winding effect. Therefore, a spinning machine for cotton yarn production is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the embodiment, Figure 1-7 A spinning machine for cotton yarn production is given, comprising a body 1, a support frame 2 is fixedly connected to the top of the body 1, four rotating seats 3 are detachably connected to the top of the support frame 2 by bolts, a rotating shaft 4 is rotatably connected between two adjacent rotating seats 3 in front and behind, and a yarn collecting drum 5 is fixedly connected to the outer sides of the two rotating shafts 4, two pressing assemblies 6 for pressing the cotton yarn are arranged at the top of the support frame 2, a first driving assembly 7 for driving the two rotating shafts 4 to rotate is arranged on the support frame 2, an internal bracket 8 is fixedly connected to the inner side of the body 1, four yarn putting shafts 9 are rotatably connected to the internal bracket 8, a second driving assembly 10 for driving the four yarn putting shafts 9 to rotate is arranged on the internal bracket 8, guide rods 11 are fixedly connected to the outer sides of the four yarn putting shafts 9, guide rings 12 are arranged on the four guide rods 11, four fixed seats 13 are fixedly connected to the support frame 2, and a receiving shaft 14 is rotatably connected to the four fixed seats 13;

[0026] The clamping assembly 6 includes a clamping shaft 61, and four clamping shafts 61 are rotatably connected to the support frame 2. The outer sides of the four clamping shafts 61 are fixedly connected with connecting arms 62, and a fixed shaft 63 is fixedly connected between two adjacent connecting arms 62. The outer sides of the two fixed shafts 63 are fixedly connected with clamping rollers 64.

[0027] Through the above arrangement, during normal operation, four pay-off drums are clamped on the outsides of the four yarn-releasing shafts 9, and the yarns on the outsides of the four pay-off drums are respectively passed through the four guide rings 12 and respectively wound around the outsides of the four receiving shafts 14 for three circles, so that the four yarns are mixed together, passed through the outside of the front yarn-collecting drum 5 for one circle, and then fixed to the outside of the rear yarn-collecting drum 5. At the same time, the first drive assembly 7 and the second drive assembly 10 are started to rotate the two rotating shafts 4 and the four yarn-releasing shafts 9. After the yarns are wound, they will pass through the outside of the front yarn-collecting drum 5 and be compacted by the front pressure roller 64. Finally, After being compacted by the rear pressure roller 64, the yarn is wound around the outer side of the rear yarn collection drum 5. The pressure roller 64 will always be pressed on the outer side of the yarn collection drum 5 due to its own weight and rotate around the fixed axis 63 to compact the yarn on the outer side of the yarn collection drum 5 (even if the yarn is knotted, it will be compacted and wound around the outer side of the yarn collection drum 5) to prevent the yarn from being scattered into a ball and unable to be normally wound around the outer side of the yarn collection drum 5.

[0031] Through the above-mentioned structural arrangement, the two second drive motors 101 are started at the same time, and the power is transmitted to the two front yarn release shafts 9 through the transmission of the two third pulley transmission mechanisms 102, so that the two front yarn release shafts 9 rotate, and then the power is transmitted to the two rear yarn release shafts 9 through the two fourth pulley transmission mechanisms 103, thereby making the four yarn release shafts 9 rotate, and after the pay-off reel is clamped on the outside of the four yarn release shafts 9, the pay-off reel can be driven to rotate.
