Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-5 The present invention provides a technical solution: a tensioning force adjusting device for polyester yarn production, comprising two symmetrically distributed mounting frames 1, each of which is provided with a slide groove 2, a connecting frame 6 is provided between the two mounting frames 1, and both ends of the connecting frame 6 are slidably connected to the inside of the slide groove 2 on both sides, and the lower parts of the two ends of the connecting frame 6 are fixedly connected to the mounting plate 5, and a tensioning roller 4 is rotatably connected between the two mounting plates 5. An adjusting slide groove 26 is provided in the middle of the connecting frame 6, and multiple groups of clamping blocks 15 are slidably arranged in the adjusting slide groove 26. The lower end of the clamping block 15 is provided with a separating mechanism. By arranging a separating mechanism at the lower end of the clamping block 15, the separating mechanism under the clamping block 15 can separate different strands of polyester yarn to prevent the polyester yarn from deviating when moving and preventing uneven tension of the polyester yarn, and the clamping block 15 can be provided with multiple groups and can slide in the adjusting slide groove 26, effectively utilizing the space on the tensioning roller 4, thereby adjusting the spacing between the separating mechanisms, so that the device can adapt to different polyester yarn diameters, thereby improving the use flexibility of the device.

[0026] like Figure 1-5As shown, the top of the connecting frame 6 is fixedly connected to a fixed plate 11, the top of the connecting frame 6 is fixedly connected to a clamping plate 14 on one side of the extrusion wedge block 21, the top of the connecting frame 6 is slidably connected to a sliding plate 13 on the other side of the extrusion wedge block 21, and the end of the fixed plate 11 is fixedly connected to a plurality of first springs 12, and the movable end of the first spring 12 is fixedly connected to the sliding plate 13. Through the elastic force of the first spring 12, the sliding plate 13 can always move toward the clamping plate 14, thereby realizing the function of clamping the clamping block 15.

[0027] like Figure 1-5 As shown, the separation mechanism includes a mounting plate 16 fixedly connected to the lower end of the clamping block 15, and both ends of the mounting plate 16 are movably connected to a separation ring 7. The two separation rings 7 are arranged around the tensioning roller 4. By setting the separation ring 7, the function of generating multiple separations on the tensioning roller 4 can be achieved.

[0028] like Figure 1-5 As shown, two symmetrically distributed connecting cavities 18 are provided in the mounting plate 16, and a second spring 20 is fixedly connected to each of the connecting cavities 18. A fixed arc piece 19 is fixedly connected to the movable end of the second spring 20, and a connecting pin 17 is fixedly connected to the top end face of the separating ring 7. The connecting pin 17 is inserted between the fixed arc piece 19 and the connecting cavity 18. The fixing function of the connecting pin 17 can be achieved by cooperating with the second spring 20 through the fixed arc piece 19, thereby completing the fixed installation of the separating ring 7.

[0029] like Figure 1-5 As shown, the mounting plate 16 is provided with a sliding cavity 23 at the positions corresponding to the two fixed arc plates 19, and a pressure plate 24 is slidably connected in the sliding cavity 23. The pressure plate 24 is fixedly connected to the fixed arc plates 19 at the corresponding positions. The pressure plates 24 on both sides can be squeezed to make the pressure plates 24 on both sides approach each other, thereby canceling the limiting function of the fixed arc plate 19 on the connecting pin 17.

[0030] like Figure 1-5 As shown, both sides of the top of the connecting frame 6 are provided with a top opening mechanism, and the top opening mechanism includes a mounting block 22 fixedly connected to the top of the connecting frame 6, and a threaded pin 25 is connected to the inner thread of the mounting block 22, and the output end of the threaded pin 25 is rotatably connected to the extrusion wedge 21, and the inclined surface of the extrusion wedge 21 is against the side of the sliding plate 13. By setting up the top opening mechanism, the extrusion wedge 21 can be driven to move toward the sliding plate 13 by rotating the threaded pin 25, and the side of the sliding plate 13 is squeezed by the oblique edge of the extrusion wedge 21, so that the sliding plate 13 is moved away from the clamping plate 14, and the fixation of the clamping block 15 can be cancelled.

[0031] like Figure 1-5As shown, both ends of the connecting frame 6 are fixedly connected with connecting plates 10, and the connecting plates 10 on both sides are respectively slidably connected to the inside of the chutes 2 on both sides, wherein a threaded rod 9 is rotatably connected to the inside of the chutes 2 on one side, and the threaded rod 9 is threadedly connected to the connecting plate 10 on the side close to it. The top of the mounting frame 1 is fixedly connected with a driving motor 3, and the output end of the driving motor 3 is fixedly connected to the threaded rod 9. By driving the driving motor 3 and cooperating with the threaded rod 9, the driving connecting frame 6 can be driven to rise and fall, thereby adjusting the tensioning force of the tensioning roller 4 on the polyester yarn.

[0032] like Figure 1-5 As shown, a guide column 8 is fixedly connected to the inside of the other side slide 2, and the guide column 8 is threadedly connected to the connecting plate 10 on the side close to it. The guide column 8 cooperates with the connecting plate 10 to guide the lifting and lowering of the connecting frame 6.

[0033] Working principle: When adjusting the tensioning roller 4 to adjust the polyester yarn, the connecting frame 6 can be driven by the driving motor 3 in conjunction with the threaded rod 9 and the connecting plate 10, thereby adjusting the height of the tensioning roller 4 and adjusting the tensioning force on the polyester yarn. In addition, the device can quickly disassemble and adjust the clamping block 15, and quickly connect the clamping block 15 and the separation mechanism. When connecting the clamping block 15 and the separation mechanism, the connecting pin 17 on the end face of the separation ring 7 is inserted between the fixed arc piece 19 and the connecting cavity 18. The fixing function of the connecting pin 17 can be achieved by the fixed arc piece 19 in conjunction with the second spring 20, and the fixed installation of the separation ring 7 can be completed. When canceling the connection, it is only necessary to squeeze the pressure plates 24 on both sides to cancel the limiting function of the fixed arc piece 19 on the connecting pin 17, and complete the disassembly of the connecting pin 17. When adjusting the position of the clamping block 15, it is only necessary to rotate the rotating threaded pin 25. The extrusion wedge 21 is driven to move in the direction of the sliding plate 13. The side of the sliding plate 13 is squeezed by the oblique edge of the extrusion wedge 21, so that the sliding plate 13 is away from the clamping plate 14, and the fixation of the clamping block 15 can be cancelled. After the threaded pin 25 is rotated in the opposite direction to reset the extrusion wedge 21, the elastic force of the deformation recovery of the first spring 12 can make the sliding plate 13 move toward the clamping plate 14, thereby realizing the function of clamping the clamping block 15. Different strands of polyester yarn can be separated by the separation mechanism under the clamping block 15 to prevent the polyester yarn from deviating during movement and to prevent uneven tension of the polyester yarn. The clamping block 15 can be provided with multiple groups and can slide in the adjusting slot 26 to effectively utilize the space on the tensioning roller 4 to adjust the spacing between the separation mechanisms, so that the device can adapt to different polyester yarn diameters, thereby improving the flexibility of use of the device.
