[0025] The following is a further detailed description of the specific implementation methods of the present invention by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of the present invention and to facilitate its implementation.

[0026] like Figures 1 to 5 As shown, the utility model provides an automatic locking and releasing device for the spindle position of a yarn rack, comprising a cylinder 1, a tensioning unit for contacting the inner wall surface of the yarn tube and for applying radial force to the yarn tube, and a telescopic rod 2 which is movably arranged and connected to the tensioning unit. The tensioning unit is rotatably arranged on the cylinder 1, and a plurality of tensioning units are provided, and the tensioning units are distributed circumferentially on the cylinder 1.

[0027] Specifically, if Figures 1 to 5 As shown, the barrel 1 is cylindrical, and the telescopic rod 2 is coaxially arranged with the barrel 1 and located at the center of the barrel 1. The tensioning units are distributed axially at multiple locations on the barrel 1. All tensioning units are arranged in multiple circles on the barrel 1. All tensioning units in the same circle are evenly distributed along the circumference with the axis of the barrel 1 as the centerline. In the locked state, all tensioning units simultaneously contact the inner surface of the bobbin, ensuring that the bobbin is securely fixed.

[0028] like Figures 1 to 4 As shown, the tensioning unit includes a connecting rod 3 and a pulley 4 rotatably arranged on the connecting rod 3 and used to contact the inner wall of the bobbin. The connecting rod 3 is rotatably connected to the telescopic rod 2. A chute 5 is provided on the connecting rod 3, and a pin 6 is provided on the barrel 1 to be inserted into the chute 5.

[0029] like Figures 1 to 4 As shown, one end of the connecting rod 3 is rotatably connected to the telescopic rod 2, and a pulley 4 is provided at the other end of the connecting rod 3. An opening is provided on the outer circumference of the barrel 1 for the pulley 4 to extend out. A chute 5 is provided between the two ends of the connecting rod 3. A pin 6 is fixedly mounted on the barrel 1. The diameter of the pin 6 is smaller than the length of the chute 5, and the chute 5 extends along the length of the connecting rod 3. When the telescopic rod 2 moves axially along the barrel 1, it causes the connecting rods 3 of all the tensioning units to swing synchronously, which in turn drives the pulleys 4 to swing synchronously, controlling the contact and separation between the pulleys 4 and the inner wall of the bobbin.

[0030] Preferably, pulley 4 includes a wheel body and an anti-slip layer disposed on the wheel body and configured to contact the inner wall of the bobbin. The wheel body is cylindrical and rotatably mounted on one end of connecting rod 3. The anti-slip layer is disposed on the outer circumference of the wheel body. The anti-slip layer is made of an elastic material with a high coefficient of friction (such as rubber) and slightly extends outside of cylinder body 1 to ensure contact with the inner circumference of the bobbin. The anti-slip layer effectively increases friction with the inner wall of the bobbin, preventing the bobbin from slipping.

[0031] like Figures 1 to 5 As shown, the telescopic rod 2 is connected to a drive mechanism 7, which is configured to control the linear movement of the telescopic rod 2 along the axis of the cylinder 1. The drive mechanism 7 mainly includes an actuator, which is connected to one end of the telescopic rod 2 and is used to drive the telescopic rod 2 to move linearly. The actuator is a retractable component and can be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.

[0032] like Figures 1 to 5 As shown, one end of the barrel 1 is connected to a baffle 8, which is provided with a pressure switch 9 for contacting the bobbin. The pressure switch 9 is electrically connected to the drive mechanism 7. When the bobbin triggers the pressure switch 9, the pressure switch 9 transmits a signal to the drive mechanism 7. The baffle 8 is on the creel, which is provided with a switch connected to a control system 12, which is connected to the drive mechanism 7. The control system 12 controls the start and stop of the actuator.

[0033] Before the bobbin is inserted: Figure 2 As shown, in the initial state, the telescopic rod 2 is in a retracted state, the connecting rod 3 is tilted, the pulley 4 is at the position with the minimum distance from the axis of the cylinder 1, the diameter of the cylinder 1 is smaller than the inner diameter of the bobbin, and the pulley 4 assists in reducing the contact area between the bobbin and the cylinder 1 and changing the sliding friction to rolling friction, which greatly reduces the friction between the bobbin and the cylinder 1, making it easier for workers to insert the bobbin into the cylinder 1.

[0034] Automatic locking: Figure 3 As shown, after the bobbin is inserted, the bottom of the bobbin contacts and depresses the pressure switch 9 on the baffle 8. This triggers the drive mechanism 7, and the actuator begins to operate, pushing the telescopic rod 2 axially toward the interior of the barrel 1. As the telescopic rod 2 moves, it causes all the connecting rods 3 to swing synchronously until they swing perpendicular to the telescopic rod 2. At this point, the pulley 4 is in close contact with the inner wall of the bobbin and is at its maximum distance from the axis of the barrel 1. The anti-slip layer on the pulley 4 contacts the inner surface of the bobbin, causing it to deform and generate a huge force and friction between the pulley and the bobbin. The tensioning unit applies radial pressure to the bobbin, achieving automatic locking of the bobbin.

[0035] Convenient release: The creel is equipped with a control switch 11, which is connected to a control system 12, which in turn controls the drive mechanism 7. To replace a bobbin, the worker simply presses the control switch 11. The control system 12 receives the signal and activates the drive mechanism 7, retracting the telescopic rod 2 and pulley 4. The pulley 4 then separates from the bobbin, allowing the bobbin to be easily removed.

[0036] The above description of the present invention is provided as an example, in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described method. Any non-substantial improvements made using the method concepts and technical solutions of the present invention, or any application of the above-described concepts and technical solutions of the present invention to other situations without modification, are all within the scope of protection of the present invention.
