When the yarn breaks later, the winding device is still working, and the broken yarn cannot be wound continuously, resulting in the overall loosening of the wound yarn, affecting the quality of the later yarn winding. Moreover, the thickness of the yarn winding cannot be prompted, and the operator still needs to check regularly during the later winding, increasing the complexity and inconvenience of its use.

[0024] Referring to Figures 1-6 , in an embodiment of the positioning device for a doubling frame of the present utility model, it includes a mounting plate 1. There are two groups of mounting plates 1. An indicator light 17 is provided at the middle position on the side of one group of mounting plates 1 away from the other group of mounting plates 1. Support rods 6 are provided at both ends of the two groups of mounting plates 1.

A starting shaft 5 and a rolling shaft 3 are respectively provided at both ends of the bottom of the two groups of mounting plates 1 on the side close to each other. At the bottom of the front end of the two support rods 6 at the same end, a fixing plate 4 is provided close to the lower side of the starting shaft 5;

[0025] A limiting rod 11 is penetrated through the middle position inside the fixing plate 4. At the top of the limiting rod 11, there is an arc-shaped resisting plate 10 that cooperates with the starting shaft 5. A first spring 9 that connects the arc-shaped resisting plate 10 and the fixing plate 4 is sleeved on the top of the outer side of the limiting rod 11. U-shaped adjusting rods 7 are penetrated through the edges at both ends inside the fixing plate 4. Fixing grooves 12 are evenly formed at the tops of both ends inside the U-shaped adjusting rods 7. Metal contact pieces 8 are provided at the inner bottom of the U-shaped adjusting rods 7 and the bottom of the limiting rod 11, and the two groups of metal contact pieces 8 cooperate with each other. Clamping components are symmetrically arranged at the middle position inside the fixing plate 4.

[0026] The clamping components include second springs 14, storage grooves 15, fixing rods 16, hinged rods 13 and pressing plates 18. There are two groups of storage grooves 15, which are formed at the middle positions at both ends inside the fixing plate 4, and one side of the two groups of storage grooves 15 communicates with the outside of the fixing plate 4. Fixing rods 16 extending into the fixing grooves 12 are provided at the ends close to each other inside the two groups of storage grooves 15. Second springs 14 connected to the fixing rods 16 are provided at the ends far from each other inside the two groups of storage grooves 15. Hinged rods 13 extending to the outside of the fixing plate 4 through the storage grooves 15 are hinged at the ends far from each other on one side of the two groups of fixing rods 16. Pressing plates 18 are jointly hinged at the ends close to each other of the two groups of hinged rods 13.

[0027] Hinge seats extending to the outside of the fixing plate 4 through the storage grooves 15 are provided at the ends far from each other on one side of the two groups of fixing rods 16, and the hinge seats are hinged and cooperate with the hinged rods 13.

[0028] Through openings are formed at the edges at both ends inside the fixing plate 4, and the through openings cooperate with the U-shaped adjusting rods 7.

[0029] Antirust coatings are sprayed on the exteriors of the first springs 9 and the second springs 14.

[0030] Working principle: During use, the yarn is wound around the outside of the starting shaft 5 through the rolling shaft 3 and the control shaft 2. At the same time, the yarn is placed inside the arc-shaped resisting plate 10. Through the cooperation between the arc-shaped resisting plate 10 and the starting shaft 5, positioning during the winding of the yarn is achieved, preventing the loosening phenomenon generated when the yarn breaks, and improving the later winding quality and tightness;

[0031] During the winding process of the yarn, the thickness of the yarn can push the arc-shaped resisting plate 10 to drive the limiting rod 11 to move downward inside the fixing plate 4 to compress the limiting rod 11. Then, through the elastic restoring force of the limiting rod 11, the resistance between the arc-shaped resisting plate 10 and the starting shaft 5 can be maintained to achieve the positioning of the yarn;

[0032] Meanwhile, by pulling the pressing plate 18, the articulated rod 13 is driven to perform articulated rotation and movement. Then, the fixed rod 16 is pulled by the articulated rod 13 to move inside the storage groove 15 to compress the second spring 14, so that the fixed rod 16 is disengaged from the inside of the fixed groove 12 to release the limit on the U-shaped adjusting rod 7. Then, the operator can directly pull the U-shaped adjusting rod 7 and the components above it to move downward inside the fixed plate 4. Furthermore, it can cooperate with the movement of the above-mentioned arc-shaped resisting plate 10 and the limiting rod 11 to realize the function of prompting the winding thickness of different yarns, without the operator checking regularly, improving the practicability and flexibility of the later use of this doubling frame;

[0033] When the U-shaped adjusting rod 7 is adjusted and the pressing plate 18 is released, through the elastic restoring force of the second spring 14, the fixed rod 16 can be driven to insert into the inside of the fixed groove 12 to fix the position of the U-shaped adjusting rod 7 after adjustment. Finally, through the movement of the limiting rod 11 and the components above it, the contact of the two groups of metal contact pieces 8 can be realized. Then, the warning lamp 17 is turned on, and the warning work is realized by the lighting of the warning lamp 17. One group of metal contact pieces 8 is connected to the power supply through an external wire, and the other group of metal contact pieces 8 is connected to the warning lamp 17 through an external wire. When the two groups of metal contact pieces 8 contact later, a closed circuit is formed and the warning lamp 17 is turned on.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present invention.
