Description

Technical Field

[0001] The utility model belongs to the technical field of textile machinery manufacturing, relates to the improvement of an automatic winder, and specifically relates to a yarn suction nozzle comb tooth and a yarn suction nozzle of an automatic winder. Background Art

[0002] An automatic winder is a device that connects fine yarn tube yarns and winds them according to the length and weight required by customers. During the winding process, after yarn defects such as neps, short thick knots, long thick knots, thin places, long thin places, and foreign fibers generated in the previous process are detected and removed by an electronic yarn clearer according to customer requirements, and after the unwinding of the fine yarn tube yarn is completed, the single-spindle CPU of the automatic winder will execute a knotting cycle, perform up and down head-seeking actions. The yarn head on the bobbin needs to enter the electronic yarn clearer for detection after the yarn suction nozzle successfully finds the head, and then enters the air twister to knot with the tube yarn head successfully found by the tube yarn suction nozzle. After successful knotting, the winding continues until the set length and weight are reached. The success rate of the upper suction head-seeking during the knotting cycle is an important link in the high production efficiency and high output of the automatic winder.

[0003] The Chinese patent discloses a utility model patent of "a device for realizing rapid capture of yarn heads" (application number: 202123003728.4). An inner steel comb is arranged on the upper part of the yarn suction nozzle of the bobbin, and the comb teeth of the inner steel comb face the inside of the suction nozzle; an outer flat steel comb is arranged on the upper outer part of the yarn suction nozzle of the bobbin, and the comb teeth of the outer flat steel comb protrude from the suction nozzle. The inner steel comb is of a U-shaped structure, and the long side of the U-shaped structure is fixed on the yarn suction nozzle of the bobbin. The flat steel comb presses on the long side of the inner steel comb, and the flat steel comb and the inner steel comb are fastened by screws. The inner steel comb plays a role in guiding the yarn into the suction nozzle. At the same time, a flat steel comb is added to the inner steel comb of the yarn suction nozzle of the bobbin. When the yarn passes through the root of the tooth shape, it has a certain clamping resistance, so that the yarn falls off from the surface of the bobbin, achieving the purpose of successfully sucking the yarn by the yarn suction nozzle of the bobbin. Due to the surface of the suction nozzle steel comb being a smooth metal surface, the grasping ability of the yarn head in a tangled state caused by short thick knots, neps, and hairiness is limited, and only by increasing the negative pressure suction can the grasping ability be enhanced. The power consumption is large and the effect is not obvious. Taking the red light alarm generated by the 72-spindle VCRO-E automatic winder due to the upper suction times reaching the set value in eight hours as an example: for 8.2 tex cotton yarn, about 120 upper limit red light alarms are generated per shift, resulting in low production efficiency and output.

[0004] How to design a yarn suction nozzle comb tooth and a yarn suction nozzle of an automatic winder, which can improve the success rate of yarn capture by the yarn suction nozzle of the bobbin, significantly reduce the number of upper suction limit alarms, improve the production efficiency and output, and has a simple structure, low cost, and is convenient for modification and installation on the existing yarn suction nozzle of the bobbin. This is an urgent technical problem in this field. Content of the Utility Model

[0006] The purpose of the utility model is realized through the following technical solutions:

[0007] A yarn suction nozzle comb tooth for an automatic winder, comprising a yarn suction nozzle comb tooth body. The yarn suction nozzle comb tooth body is a U-shaped structure made of stainless steel. One side edge of the yarn suction nozzle comb tooth body is a comb tooth, and an installation hole is provided on the other side surface of the yarn suction nozzle comb tooth body for installation on the yarn suction nozzle. The feature is that the outer surface of the yarn suction nozzle comb tooth body along the side where the comb tooth is arranged has uniformly sprayed fine particles.

[0015] 1. After laser etching the surface of the comb teeth body of the cheese suction nozzle of the present utility model that is closest to the cheese, 110-160 mesh silica particles are sprayed. During the yarn suction process, the rough surface generated by the silica particles catches the fluff on the yarn head, peels off the yarn head that is entangled with the fluff on the cheese surface from the cheese surface, and is captured by the cheese suction nozzle that generates negative pressure air. Thus, on the premise that the cheese suction nozzle does not contact the cheese surface, the yarn head is smoothly sucked into the cheese suction nozzle to complete the knotting process, which can reduce the number of red light alarms for upward suction, improve the success rate of yarn capture at one time, and increase both production efficiency and output.

[0022] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] See Figures 1-4 , an embodiment of the comb teeth of the cheese suction nozzle of an automatic winder of the present utility model, includes a comb teeth body 1 of the cheese suction nozzle. The comb teeth body 1 of the cheese suction nozzle is a U-shaped structure made of stainless steel. One side edge of the comb teeth body 1 of the cheese suction nozzle is comb teeth 1.2, and a mounting hole 1.3 is provided on the other side surface of the comb teeth body 1 of the cheese suction nozzle for mounting on the cheese suction nozzle body 2. Uniformly sprayed particles 1.1 are provided on the outer surface of the comb teeth body 1 of the cheese suction nozzle on the side where the comb teeth 1.2 are arranged along the edge.

[0024] Furthermore, the outer surface of the comb teeth body ① of the cheese suction nozzle for spraying the particles 1.1 has fine vertical and horizontal stripes formed by laser etching.

[0025] Furthermore, the above-mentioned particulate matter 1.1 is silica particulate matter with a mesh size of 110 - 160.

[0026] Preferably, the width of the area where the particulate matter 1.1 is sprayed on the bobbin yarn suction nozzle comb body 1 is 5 - 6 mm, and the length is 140 - 150 mm. The length of the comb teeth 1.2 is 148 - 150 mm, and the number of teeth of the comb teeth 1.2 is 168 - 170.

[0027] Still further, the above-mentioned bobbin yarn suction nozzle comb body 1 is an integral structure formed by stamping and bending a stainless steel plate.

[0028] The specific processing method of the present utility model: Laser etching is performed on the metal steel comb on the large suction nozzle of the automatic winder at the surface where the yarn suction and air suction airflow act to maintain the firmness of spraying, and then silica particulate matter with a mesh size of 110 - 160 is sprayed. The spraying density is 0.5 - 2 mg of silica particulate matter per square millimeter. The surface is required to be uniform, without dot-like accumulation and the spraying area exceeding the required acting surface range.

[0029] See Figures 1-4 , an embodiment of a bobbin yarn suction nozzle of the present utility model, includes a bobbin yarn suction nozzle body 2 and a suction nozzle comb installed at the opening of the bobbin yarn suction nozzle body 2. The suction nozzle comb is the bobbin yarn suction nozzle comb of the automatic winder in the above-mentioned embodiment. Specifically, screws are used to install it on the opening of the bobbin yarn suction nozzle body 2 through the installation holes 1.3 opened on the side of the bobbin yarn suction nozzle comb body 1, so that the comb teeth 1.2 face the inside of the opening of the bobbin yarn suction nozzle body 2, and the surface sprayed with the particulate matter 1.1 faces the surface of the bobbin yarn 5.

[0030] During use, during the yarn suction process, the rough surface generated by the silica particulate matter catches the hairs on the yarn end 3, and the yarn end 3 that is entangled with the hairs on the surface of the bobbin yarn 5 is peeled off from the surface of the bobbin yarn 5 and captured by the bobbin yarn suction nozzle that generates negative pressure wind ( Figure 4 the air flow direction 4 shown). Thus, the yarn end 3 can be smoothly sucked into the bobbin yarn suction nozzle to complete the knotting process without the bobbin yarn suction nozzle contacting the surface of the bobbin yarn 5, which can reduce the number of upper suction red light alarms, improve the success rate of the first yarn capture, and increase both the production efficiency and the output.

[0031] The utility model relates to a practical solution for improving the success rate of the upper suction head seeking in the knotting cycle of an automatic winder in the winding process of a textile factory. By coating the surface of the existing upper suction nozzle steel comb with emery (silica particles of 110-160 mesh), the yarn ends 3 on the cheese 5 can be effectively grasped. Even if these yarn ends 3 may be tangled with the surface of the cheese 5 due to yarn defects such as neps and hairiness, the previously used upper blowing nozzle steel comb has a smooth metal surface and has limited grasping ability for the yarn ends 3 in a tangled state caused by short and thick knots, neps, and hairiness. Only by increasing the negative pressure suction can the grasping ability be enhanced, resulting in a large power consumption and an insignificant effect. Taking the red light alarm generated by the 72-spindle VCRO-E automatic winder due to the upper suction times reaching the set value in eight hours as an example: for 8.2 tex cotton yarn, about 120 upper limit red light alarms are generated per shift. After spraying emery of 110-160 mesh, it can be reduced to about 60-70 times. The number of upper suction limit alarms is reduced by about 50%, the production efficiency is increased by about 5%, the output is increased by about 10%, and the labor intensity of the loom fixer is reduced (calculated by each person fixing four 72-spindle VCRO-Es, the average number of cheese suction nozzle alarm red lights per shift is reduced by 200). A large number of ineffective knotting cycles are reduced, power consumption is saved, and the internal quality of the cheese is ensured due to the reduction of ineffective cycles.

[0032] Certainly, the above description is not a limitation of the utility model, nor is the utility model limited to the above examples. Any changes, modifications, additions, or substitutions made by those of ordinary skill in the art within the scope of the essence of the utility model shall also fall within the protection scope of the utility model.
