Description

Technical Field

[0001] The invention relates to the technical field of cotton textile, in particular to a spindle inserting device of an automatic winding machine. Background Art

[0002] At present, many domestic textile industries are mostly using imported or domestically modified automatic winding machines. Each single spindle of the automatic winding machine has a drive shaft 3 on the yarn insertion seat. The flat positioning pin 1 and the clamping pin 2 pass through the drive shaft 3 and are fixed on the drive shaft 3 with the shaft end fixing nut 4. The flat positioning pin 1 and the clamping pin 2 form an angle of 60 degrees. Figure 1 , Figure 2 As shown. When the automatic bobbin-returning machine returns the bobbin, the returned cone-shaped bobbin is transferred from the yarn storage of the machine to the top of the slideway. At this time, the cone-shaped bobbin will slide down along the slideway below to the yarn insertion spindle device. During the process of the cone-shaped bobbin sliding down along the slideway, the flat positioning pin 1 is driven to move in the positive direction of the clamping pin 2 by the clockwise rotation of the driving shaft 3 on the yarn insertion seat, so that the angle between the flat positioning pin 1 and the clamping pin 2 becomes smaller. After the returned cone-shaped yarn covers the flat positioning pin 1 and the clamping pin 2, the flat positioning pin 1 is rotated counterclockwise again by the driving shaft 3 on the yarn insertion seat, and then moves in the opposite direction of the clamping pin 2. The angle is opened during this period, and the returned cone-shaped bobbin is supported. The supported cone-shaped bobbin yarn is wound on the grooved cylinder of the single spindle to form a bobbin yarn through the large and small suction nozzles on the single spindle and the knotting of the splicer. However, during the production process, the diameters of the bottoms of some returning conical tubes are different, some are large-diameter and some are small-diameter, but the size of this yarn insertion device is fixed, and it is impossible to simultaneously meet the needs of returning conical tubes of various diameters. In addition, when the flat positioning pin 1 is used, when the conical tube yarn is inserted, it often tilts left and right, which affects the unwinding of the tube yarn and the forming of the tube yarn, and reduces the production efficiency. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a spindle inserting device for an automatic winding machine to enable winding of conical tubes of different diameters on the same machine.

[0004] To achieve the above-mentioned purpose of the invention, the conical positioning pin of the present invention is combined with the positioning pin fixing rod, the positioning screw fixing gasket and the fixing nut as an integral whole. The conical positioning pin passes through the driving shaft through the positioning pin fixing rod and the clamping pin, and is fixed to the driving shaft with the shaft end fixing nut and the fixing gasket. The positioning pin fixing rod and the clamping pin form an angle of 60 degrees, and the conical positioning pin is a conical structure with a small top and a large bottom.

[0005] The upper end diameter of the conical positioning pin is 35mm, the lower end diameter is 45mm, and the height is 40mm. A concave circular surface is provided at the upper end with the center point as the center of the circle. The positioning screw penetrates the conical positioning pin from top to bottom from the center of the conical positioning pin and is connected to the upper end of the positioning pin fixing rod.

[0006] The upper end of the positioning screw is flush with the upper end of the cone positioning pin.

[0007] Compared with the prior art, the cone positioning tube pin is designed into a cone in the present invention. When a large-diameter cone tube is returned to the tube, the cone tube slides downward for a distance; when a small-diameter cone tube is returned to the tube, the cone tube is lifted upward for a distance. This can effectively meet the production requirements of returning cone tubes of different diameters, and can adapt to the production requirements of returning cone paper tubes and plastic tubes of large and small diameters. The present invention has a simple structure and low cost. The cone yarn is not easy to skew, which improves the production efficiency and utilization rate of the equipment and reduces the labor intensity of maintenance personnel.

[0014] like Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the cone positioning pin 5 of the present invention is combined with the positioning pin fixing rod 6, the positioning screw 9, the fixing gasket 7 and the fixing nut 8 as a whole. The cone positioning pin 5 passes through the driving shaft 3 through the positioning pin fixing rod 6 and the clamping pin 2, and is fixed to the driving shaft 3 by the shaft end fixing nut 4 and the fixing gasket 7. The positioning pin fixing rod 6 and the clamping pin 2 form an angle of 60 degrees. The cone positioning pin 5 is a cone structure that is small on the top and large on the bottom. When the automatic rewinding machine returns the bobbin, the returned conical bobbin yarn (large bobbin yarn 10 or small bobbin yarn 11) is transferred from the yarn storage of the machine to the top of the slideway. At this time, the conical bobbin yarn will slide downward along the slideway below to the yarn insertion spindle device. During the process of the conical bobbin yarn sliding downward along the slideway, the cone positioning pin 5 is driven to move in the positive direction of the clamping pin 2 by the clockwise rotation of the driving shaft 3 on the yarn insertion seat, so that the angle between the cone positioning pin 5 and the clamping pin 2 becomes smaller. After the returned conical bobbin yarn covers the cone positioning pin 5 and the clamping pin 2, the cone positioning pin 5 rotates counterclockwise again through the driving shaft 3 on the yarn insertion seat, and then moves in the opposite direction of the clamping pin 2. During this period, the angle is opened to support the returned conical bobbin yarn.

[0015] The upper end diameter of the cone positioning pin 5 is 35mm, the lower end diameter is 45mm, and the height is 40mm. A concave circular surface with a diameter of 18mm and a depth of 5mm is provided at its upper end with the center point as the center of the circle. The positioning screw 9 penetrates the cone positioning pin 5 from top to bottom from the center of the cone positioning pin 5. After being connected to the upper end of the positioning pin fixing rod 6, the upper end of the positioning screw 9 is flush with the upper end of the cone positioning pin 5.

[0016] The present invention is generally applicable to large-bobbin yarn 10 and small-bobbin yarn 11. In practical applications, the large-bobbin yarn 10 and small-bobbin yarn 11 are not easily skewed after being inserted into the conical positioning pin 5, and the yarn is not easily broken when unwinding, which effectively eliminates the situation in which the operator needs to replace flat positioning pins of different models due to conical bobbins of different diameters, thereby greatly improving work efficiency, saving production costs, and reducing the labor intensity of operators.
