Description

Technical Field

[0001] The utility model relates to the field of textiles, and more specifically, to a shuttle rotating edge yarn device. Background Art

[0002] The shuttle rotating edge yarn refers to the edge tissue formed by winding the weft and yarns to form a woven belt. The edge tissue of a conventional shuttleless loom is formed by the cooperation of a weft needle and a tongue needle for edge hooking. The weft needle feeds the weft yarn to one side, and the tongue needle hooks the weft and winds it with the yarn to form the edge tissue of the woven belt. However, the edge hooking by the tongue needle is prone to edge detachment, resulting in the yarn not being wound with the weft, leading to the overall loosening of the woven belt. For some woven belts used in special scenarios, the edge tissue needs to be further reinforced, resulting in waste of time and cost. Therefore, there is an urgent need for a device that can replace the tongue needle to realize the winding of the weft and yarns to form the edge tissue of the woven belt.

[0024] Embodiment

[0025] Refer to Figures 1-4As shown in the figure, the present utility model discloses a shuttle edge yarn device, which includes a base 10 and a rotating body 20. The base 10 includes a circular groove opened, and a notch 105 is opened on one side of the circular groove. Specifically, the base 10 includes a semi-circular support 101 and a semi-circular cover plate 102. The semi-circular cover plate 102 is locked to the semi-circular support 101 by bolts. The semi-circular support 101 and the semi-circular cover plate 102 are closed to form a circular groove. One side after the semi-circular support 101 and the semi-circular cover plate 102 are closed forms a notch 105. The assembled base 10 is convenient for taking out the rotating body 20 from the circular groove. A rotating shaft 103 is arranged at the bottom of the circular groove, and a dial 104 is installed on the rotating shaft 103. The rotating shaft 103 is arranged on the semi-circular support 101. The rotation of the rotating shaft 103 drives the rotation of the dial 104. The dial 104 includes a fixing piece for connecting the rotating shaft 103 and a top abutting part for pushing the rotating body 20. The fixing piece is locked to the end face of the rotating shaft 103 placed in the circular groove by bolts. The two top abutting parts do not directly contact the rotating body 20. By rotating the rotating shaft 103, the top abutting part of the rotating body 20 rotates to push the rotating body 20 to rotate in the circular groove.

[0026] Furthermore, one side of the semi-circular support 101 extends a fixing plate, and a strip-shaped hole is opened on the fixing plate. It is installed on the webbing equipment through the strip-shaped hole at the bottom.

[0027] Referring to Figures 1-4 As shown in the figure, the rotating body 20 is semi-circular. The rotating body 20 is provided with a receiving hole 201. A hook line part 202 protrudes from one side edge of the rotating body 20. A roller 2011 is detachably installed in the receiving hole 201. Rotating the dial 104 drives the rotating body 20 to rotate in the circular groove. Specifically, fixing holes and sliding grooves are respectively opened on both side walls in the receiving hole 201. One end of the roller 2011 is bent to form a bent part. When installing the yarn bobbin, the bent part at one end of the roller 2011 is slid out of the receiving hole 201 along the sliding groove, and then the other end of the roller 2011 is pulled out from the fixing hole. The yarn bobbin is sleeved on the roller 2011 and then installed back into the receiving hole 201. Furthermore, a wire guiding ring 204 is arranged on the end face of the rotating body 20 away from the rotating shaft 103. The free end of the yarn passes through the wire guiding ring 204. The wire guiding ring 204 plays a role in guiding the yarn.

[0028] Referring to Figures 1-4 As shown in the figure, a pre-tightening mechanism 203 is further arranged in the receiving hole 201. The pre-tightening mechanism 203 includes a pre-tightening spring 2031 and a pressing piece 2032. The pressing piece 2032 is pressed on the roller 2011 by the pre-tightening spring 2031. Specifically, after the yarn bobbin is installed on the roller 2011, the pressing piece 2032 presses the yarn bobbin under the action of the pre-tightening spring 2031, so that the yarn bobbin is placed in the receiving hole 201 to avoid falling off.

[0029] Specific operation process: Load the yarn bobbin into the accommodating cavity, let the free end of the yarn pass through the wire loop 204, use the weft needle to push the weft yarn to the notch 105, rotate the rotating shaft 103 to drive the yarn-hooking part 202 to hook the weft yarn and rotate, so that the weft yarn and the yarn are wound together, thus realizing the formation of the webbing edge structure.

[0030] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
