[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly defined and limited, the terms "installation", "provided with", "connected", and "connection" should be understood in a broad sense; for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium, and it can be the communication between two components inside. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0022] Please refer to Figure 1 , a constant tension control device for polyester thread, including a rotating shaft 1, a magnetic tension controller 2, and a tension clamping assembly 6. The tension clamping assembly 6 is provided on the rotating shaft 1, and a thread reel 4 is provided on the outer wall of the tension clamping assembly 6; during operation, the inner wall inner diameter of the thread reel 4 is opened, squeezed, and clamped through the tension clamping assembly 6, which facilitates the winding and other operations of the polyester thread on the thread reel 4, ensures safety, and facilitates the use of the device.

[0023] An inclined panel 8 is provided inside the tension clamping assembly 6. A pneumatic tensioning shaft 5 is movably provided on the upper surface of the inclined panel 8. One side of the inclined panel 8 is in contact with a compression spring 7, and an air pump 3 is provided on the other side of the inclined panel 8. The air pump 3 is communicatively connected to the magnetic tension controller 2. The magnetic tension controller 2 is installed on the rotating shaft 1. During operation, the air pump 3 is controlled by the magnetic tension controller 2 to work. When the thread reel 4 needs to be removed or installed, the air pump 3 is turned on to blow the inclined panel 8, causing the inclined panel 8 to move towards the side of the compression spring 7. The pneumatic tensioning shaft 5 will then roll from the high position to the low position of the inclined panel 8. In this way, the pneumatic tensioning shaft 5 will drop, and the pneumatic tensioning shaft 5 will be separated from the inner diameter ring wall of the thread reel 4, making it easy to remove or install the thread reel 4, which is beneficial to the quick installation and removal of the thread reel 4; when the thread reel 4 needs to be clamped, the magnetic tension controller 2 controls the air pump 3 to close, and the inclined panel 8 will move back to the side close to the air pump 3 under the action of the compression spring 7. The pneumatic tensioning shaft 5 will then roll from the low position to the high position of the inclined panel 8. In this way, the pneumatic tensioning shaft 5 will rise, and the pneumatic tensioning shaft 5 will contact and clamp the inner diameter ring wall of the thread reel 4 to ensure the stability of the thread reel 4; and the safety is increased.

[0024] There are multiple sets of tension clamping assemblies 6, with 2 - 6 sets of tension clamping assemblies 6. During operation, through the coordinated action of multiple sets of tension clamping assemblies 6, it is convenient to expand, squeeze, and clamp the inner diameter of the wire reel 4, facilitating operations such as winding polyester thread on the wire reel 4, ensuring safety, and facilitating the use of the device.

[0025] One side of the highest end of the inclined panel 8 is close to the compression spring 7, and one side of the lowest end of the inclined panel 8 is close to the pneumatic pump 3, facilitating the back - and - forth movement of the inclined panel 8, facilitating the use of the device, and ensuring safety.

[0026] The pneumatic tensioning shaft 5 is movably arranged inside the tension clamping assembly 6. There are sliding rails inside the tension clamping assembly 6, and the pneumatic tensioning shaft 5 is arranged in the sliding rails. The sliding rails are perpendicular to the central axis of the rotating shaft 1. During operation, the pneumatic tensioning shaft 5 can move up and down, facilitating the clamping of the wire reel 4.

[0027] The pneumatic pump 3, the inclined panel 8, and the compression spring 7 are arranged in one - to - one correspondence, facilitating the control of each pneumatic tensioning shaft 5, facilitating the use of the device, and ensuring safety.

[0028] The air outlet of the pneumatic pump 3 is close to the lowest end of the inclined panel 8. During operation, it is convenient for the pneumatic pump 3 to provide power in a timely manner to blow the inclined panel 8, facilitating the sliding of the inclined panel 8, increasing safety, and facilitating the use of the device.

[0029] There are parallel sliding rails inside the tension clamping assembly 6, and the inclined panel 8 is movably arranged on the parallel sliding rails. During operation, the inclined panel 8 can move back and forth on the parallel sliding rails, facilitating the lifting and lowering of the subsequent pneumatic tensioning shaft 5, ensuring safety, facilitating the use of the device, and facilitating the operation of the device.

[0030] During the operation of the present invention, the pneumatic pump 3 is controlled by the magnetic tension controller 2, and through the coordinated action of the compression spring 7, the rise or fall of the pneumatic tensioning shaft 5 is controlled, making it easy to clamp or remove and install the wire reel 4, facilitating the quick loading and unloading of the wire reel 4; ensuring the stability of the wire reel 4, increasing safety, extending the service life of the device, ensuring the constancy of tension, and avoiding the instability of tension caused by long - term operation.

[0031] There is a clamping block plate above the top of the pneumatic tensioning shaft 5. The clamping block plate increases the clamping effect of the device, facilitating the subsequent extrusion and clamping of the inner diameter and inner wall of the wire reel, facilitating the clamping of the wire reel, increasing safety, facilitating the control of the quick loading and unloading of the wire reel, increasing safety, and facilitating the use of the device.

[0032] The described tension clamping assemblies 6 are evenly circumferentially arranged around the outer wall of the rotating shaft 1. According to the actual situation, through multiple sets of tension clamping assemblies 6 arranged evenly in a circle, the stability and uniformity of the wire reel clamping points are ensured, avoiding the subsequent dropping of the wire reel, increasing safety, and facilitating the use of the device.

[0033] An alternative to the present invention may be to replace the compression spring 7 with another set of pneumatic pumps 3. One set of pneumatic pumps 3 is provided at each end of the inclined panel 8. The pneumatic pumps 3 are communicatively connected to the magnetic tension controller 2. The magnetic tension controller 2 facilitates the control of the pneumatic pumps 3 at both ends of the inclined panel 8. By the staggered cooperative operation of the pneumatic pumps 3 at both ends of the inclined panel 8, it is convenient to ensure the reciprocating movement of the inclined panel 8, facilitate the control of the lifting of the pneumatic tensioning shaft 5, and ensure the operation of the device.
