In the figure, 1, a pay-off stand; 11. installing a shaft; 111. an external thread; 2. a pay-off drum; 3. a limiting ring; 4. a positioning ring; 5. a limiting block; 6. a bearing block; 7. chamfering; 8. The anti-drop nut.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
In this embodiment: refer to fig. 1, do the utility model discloses a pay-off with limit structure, including pay off rack 1, can dismantle through the bolt on the pay off rack 1 and be fixed with a plurality of installation axles 11, install the spool 2 of installing 11 outside covers and establishing rather than rotating the connection. Wherein, the installation axle 11 adopts plastic materials to make, and the aperture of the centre bore of the pay off section of thick bamboo 2 is greater than the diameter of installation axle 11. When pay-off carries out the unwrapping wire to pay-off section of thick bamboo 2, under the tractive power of feeder or weaving machine self, pay-off section of thick bamboo 2 rotates around installation axle 11 and carries out the unwrapping wire to carry the yarn to weaving machine and weave in.
Because the aperture of the centre bore of a pay off section of thick bamboo 2 is greater than the diameter of installation axle 11, so at the in-process that pay off section of thick bamboo 2 rotated the unwrapping wire, the easy slope that takes place of a pay off section of thick bamboo 2 makes the inner wall of a pay off section of thick bamboo 2 and the outer wall direct contact of installation axle 11 to the frictional force increase that receives when making the unwrapping wire of a pay off section of thick bamboo 2, causes a pay off section of thick bamboo 2 unwrapp. Therefore, the limiting structure capable of limiting the pay-off drum 2 when the pay-off drum 2 pays off the line needs to be arranged, so that the central shaft of the installation shaft 11 coincides with the central shaft of the pay-off drum 2 as far as possible in the pay-off process of the pay-off drum 2.
Referring to fig. 1, the limiting structure includes a limiting ring 3 sleeved on the installation shaft 11 and a limiting block 5 fixedly disposed on the installation shaft 11.
Wherein, spacing ring 3 is located the top of a pay off section of thick bamboo 2, and the outer wall of spacing ring 3 and the inner wall looks butt of a pay off section of thick bamboo 2, inner wall and the outer wall looks butt of installation axle 11, and spacing ring 3 rotates with a pay off section of thick bamboo 2 to be connected. In order to facilitate the limiting ring 3 to be sleeved into the mounting shaft 11, a chamfer 7 is arranged on the edge of one side of the limiting ring 3 away from the positioning ring 4, and the aperture of the central hole of the limiting ring 3 is slightly larger than the diameter of the mounting shaft 11, in this embodiment, the aperture of the central hole of the limiting ring 3 is 0.5-1 mm larger than the diameter of the mounting shaft 11.
Because pay off section of thick bamboo 2 pivoted in-process drives the spacing ring 3 gliding easily, in this embodiment, the one end of spacing ring 3 has integrated into one piece's holding ring 4 along radially extending, and the external diameter of holding ring 4 is greater than the internal diameter of pay off section of thick bamboo 2, and the top of pay off section of thick bamboo 2 is located to holding ring 4 lid, is favorable to fixing a position spacing ring 3.
In order to reduce the possibility that the pay-off drum 2 falls off from the mounting shaft 11 when the pay-off drum 2 rotates, an external thread 111 is arranged at one end, away from the limiting block 5, of the mounting shaft 11, an anti-falling nut 8 is in threaded fit with the outer peripheral side of the mounting shaft 11, and one side of the anti-falling nut 8 is abutted to one side, away from the limiting ring 3, of the positioning ring 4.
For the frictional force between yarn and the holding ring 4 on reducing the unwrapping wire section of thick bamboo 2, holding ring 4 is the smooth surface towards one side of unwrapping wire section of thick bamboo 2, like glass smooth surface etc.
In addition, stopper 5 is located the bottom of a pay off section of thick bamboo 2, and the outer wall of stopper 5 and the inner wall looks butt of a pay off section of thick bamboo 2, and stopper 5 rotates with a pay off section of thick bamboo 2 to be connected. In order to insert the pay-off drum 2 into the limiting block 5, a chamfer 7 is arranged on the edge of one side, away from the bearing block 6, of the limiting block 5.
One end of the limiting block 5 radially extends to form a bearing block 6, and the diameter of the bearing block 6 is larger than that of the limiting block 5 and can be used for bearing the pay-off drum 2. For the frictional force between yarn and the carrier block 6 that reduces on the payoff barrel 2, one side that carrier block 6 faced payoff barrel 2 is the smooth surface, like glass smooth surface etc..
The implementation principle of the embodiment is as follows: embolia stopper 5 with the bottom of a pay off section of thick bamboo 2, and insert the top of a pay off section of thick bamboo 2 with spacing ring 3, make holding ring 4 lid establish at the top of a pay off section of thick bamboo 2, then screw in anti-disengaging nut 8, one side butt that makes anti-disengaging nut 8 be close to holding ring 4 keeps away from one side of spacing ring 3 at holding ring 4, at pay off section of thick bamboo 2 pivoted in-process, because pay off section of thick bamboo 2 receives the spacing effect of the spacing ring 3 at top and the stopper 5 of bottom, thereby can ensure that pay off section of thick bamboo 2 is at the pivoted in-process, the central line of pay off section of thick bamboo 2 coincides mutually with the central line of installation axle 11, be favorable to reducing the possibility that the contact produced friction between pay off section of thick bamboo 2 and the installation axle 11.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
