[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 This utility model provides a technical solution: a tension-adjustable vibrating yarn spreading device, including a mounting base 1, a vibrating spreading roller 5 and a vibrating spreading roller 502. The mounting base 1 has symmetrically welded connecting ears 101 on both sides, and the connecting ears 101 have symmetrically opened connecting holes inside. The mounting base 1 has a control box 2 installed inside, and an operation screen 201 is connected to one side of the control box 2. The mounting base 1 has guide rollers 3 and carding rollers 4 connected to both sides, which are used to guide and card the yarn respectively. The mounting base 1 has vibrating spreading roller 5 and vibrating spreading roller 502 inside, which are used to vibrate and spread the yarn.

[0027] This utility model allows the mounting base 1 to be installed via the connecting ear 101 and the connecting hole inside the connecting ear 101. After the operation screen 201 sends the command to the control box 2, the control box 2 controls the guide roller 3 to guide the movement direction of the yarn entering the vibrating yarn spreading device. The yarn is vibrated and spread by the first vibrating spreading roller 5 and the second vibrating spreading roller 502. The yarn is then combed and discharged by the combing roller 4.

[0028] exist Figures 1-3In the middle: both ends of the vibrating roller 5 are connected to the moving frame 501, so that the vibrating roller 5 moves synchronously with the moving frame 501. The mounting base 1 has two sets of guide grooves 504 symmetrically opened inside. Both ends of the vibrating roller 502 pass through the guide grooves 504 and are connected to the moving frame 503, so that the vibrating roller 502 moves synchronously with the moving frame 503 along the guide grooves 504. The vibrating roller 5 and the vibrating roller 502 are staggered inside the mounting base 1.

[0029] The movable frame 501 and movable frame 503 of this utility model can drive the interleaved vibrating spreading roller 5 and vibrating spreading roller 502 to push the yarn in opposite directions, so as to facilitate the full unfolding of the yarn.

[0030] exist Figure 3 and Figure 4 In the middle: both the first movable frame 501 and the second movable frame 503 have threaded grooves 505 inside, and the threads inside the two threaded grooves 505 are set in opposite directions. A drive rod 506 is inserted into the middle of the threaded groove 505, and the outer side of the drive rod 506 is connected to a first adjusting thread 5061 and a second adjusting thread 5062 with opposite directions, which are used to connect with the threaded grooves 505 inside the first movable frame 501 and the second movable frame 503 respectively. A speed regulating motor 507 is installed inside the mounting base 1 by locking bolts. The output end of the speed regulating motor 507 is connected to the drive rod 506 through a coupling.

[0031] This invention starts the speed-regulating motor 507. The output end of the speed-regulating motor 507 drives the drive rod 506 to rotate via a coupling. The drive rod 506, through the first adjusting thread 5061 and the second adjusting thread 5062 connected to the outside, interacts with the threaded grooves 505 inside the moving frame 1 501 and the moving frame 2 503, respectively. This causes the moving frame 1 501 and the moving frame 2 503, as well as the vibrating spreading roller 1 5 and the vibrating spreading roller 2 502 inside the moving frame 1 501 and the moving frame 2 503, to move in opposite directions to vibrate and spread the yarn. At this time, by adjusting the speed and working time of the speed-regulating motor 507, the moving distance and moving speed of the moving frame 1 501 and the moving frame 2 503 can be adjusted, thereby realizing the adjustment of the tension of the vibrating yarn spreading device. This allows the yarn to be fully spread during the vibration process. The operation is simple and convenient.

[0032] exist Figures 3-5 In the middle: The movable frame 503 has an installation groove 6 inside, and a pressure sensor 601 is installed inside the installation groove 6. The pressure sensor 601 is of model HYLF-101-2. A protective film 602 is provided on the outside of the installation groove 6 to protect the pressure sensor 601. The bottom of the protective film 602 is adhered to the movable frame 503.

[0033] When the yarn unfolding process is completed and the speed-regulating motor 507 is started, driving the first moving frame 501 and the second moving frame 503 to reset, as the first moving frame 501 and the second moving frame 503 continue to approach each other, the lower surface of the first moving frame 501 will come into contact with the protective film 602 at the second moving frame 503. This will push the protective film 602 to contact the pressure sensor 601 and squeeze it. At this time, after the pressure sensor 601 senses the pressure signal, it will transmit the pressure signal to the control box 2, which will then control the start and stop of the speed-regulating motor 507 to avoid collision and excessive compression between the first moving frame 501 and the second moving frame 503.

[0034] exist Figure 3 and Figure 4 In the middle: a guide rod 7 is welded to the inner side of the mounting base 1. The outer side of the guide rod 7 is inserted into the guide post 701. The top of the guide post 701 is welded to the movable frame 1 501. The guide post 701 and the guide rod 7 are symmetrically arranged at the bottom of the movable frame 1 501. The movable frame 2 503 has an insertion groove 702 inside for insertion with the guide post 701. The inner side of the insertion groove 702 and the bottom of the guide post 701 are both arc-shaped to ensure accurate insertion of the guide post 701 into the insertion groove 702.

[0035] The insertion and connection of the guide post 701 and guide rod 7 of this utility model can effectively improve the stability of the first mobile frame 501 during movement. The outer side of the guide post 701 is inserted into the insertion groove 702 inside the second mobile frame 503, which not only improves the stability of the first mobile frame 501 during movement, but also further enhances the stability of the second mobile frame 503 during movement.

[0036] Working principle: When using the tension-adjustable vibrating yarn spreading device of this utility model, the yarn is passed sequentially through the gap between the two guide rollers 3, the vibrating spreading roller 1 5 and the vibrating spreading roller 2 502, and the two carding rollers 4. After the operation screen 201 sends the command to the control box 2, the output end of the speed-regulating motor 507 is controlled by the control box 2 to drive the drive rod 506 to rotate through the coupling. The first adjusting thread 5061 and the second adjusting thread 5062 interact with the threaded grooves 505 inside the moving frame 1 501 and the moving frame 2 503, respectively, driving the vibrating spreading roller 1 5 and the vibrating spreading roller 2 502 to move in opposite directions to vibrate and spread the yarn. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
