Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a tension regulating structure for yarn winding. Background Art

[0002] Currently, during the yarn winding process, since the middle stroke of the yarn is long, the yarn will drag on the ground due to insufficient tension during the winding process, which will cause the yarn to be contaminated.

[0003] To solve the above problems, there is a solution of a tension adjustment structure for yarn winding (Announcement No. CN216638501U), in which the yarn is passed around two tensioning rollers, and the positions of the two tensioning rollers are adjusted by moving the positions of the two tensioning rollers in the adjustment grooves through the cooperation of the positioning rods, positioning holes and side plates, thereby increasing the tension in the middle section of the yarn.

[0004] However, the above scheme requires presetting the position of the tensioning roller and then winding the yarn around the tensioning roller. During the yarn winding process, if the yarn becomes loose, it is necessary to manually adjust the position of the tensioning roller again. The tensioning state of the yarn cannot be freely adjusted according to the tightness of the yarn. When the yarn is loose, the yarn is easy to slide on the tensioning roller, and the winding of multiple yarns is easy to interfere with each other. Utility Model Content

[0005] The utility model aims to provide a tension regulating structure for yarn winding to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a yarn winding tension adjustment structure, comprising a base, support rods are installed on the left and right sides of the base surface, two guide rollers are installed on the support rod surface, the guide rollers support the yarn, and when the yarn is in a relaxed state, the guide rollers can prevent the yarn from relaxing and touching the ground;

[0007] Two electric cylinders are installed on the surface of the base, and a cylinder shell is installed on the upper end of the electric cylinder. A spring and a push rod located on the upper end of the spring are placed inside the cylinder shell. The upper end of the push rod is rotatably connected to a drum. A plurality of annular grooves are provided on the surface of the drum. The annular grooves are used to limit the position of the yarn. The spring pushes the push rod so that the drum can adjust the tension of the yarn winding.

[0008] The height of the drum can be adjusted by using an electric cylinder. If the yarn is loose when winding, the electric cylinder can be used to tighten the yarn without manual adjustment.

[0009] Furthermore, a plurality of pulleys are sleeved on the surface of the guide roller, and the upper and lower rows of pulleys are aligned and arranged. When the yarn is wound on the pulleys, the pulleys can prevent the yarn from deviating left and right during the winding process and prevent the yarns from being entangled with each other.

[0010] Furthermore, three slide grooves are provided on the surface of the push rod, and a number of universal beads are installed on the surface of the cylinder shell, and the universal beads are rollingly connected to the slide grooves. The universal beads can reduce the resistance of the push rod to move up and down. When the yarn is tightened, the yarn can press down the drum to avoid the yarn being too tight.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The annular groove on the drum prevents each yarn from being entangled with each other. The spring pushes the top rod to drive the drum upward. When the yarn is in a relaxed state, the tension of the yarn can be automatically adjusted, and the yarn is not prone to relaxation during winding.

[0013] (2) The yarn is limited by two rows of upper and lower pulleys. When the yarn is taut, it can prevent the yarn from moving upward, and when the yarn is loose, it can prevent the yarn from moving downward. The pulley can also prevent the yarn from moving left and right, ensuring that the yarn will not be tangled when winding. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example:

[0022] See also Figure 1-5 The utility model provides a technical solution: a tension adjustment structure for yarn winding, comprising a base 1, support rods 2 are installed on both sides of the base 1, and two guide rollers 3 are installed on the surface of the support rods 2;

[0023] Four support rods 2 are provided to stably support the guide rollers 3. The guide rollers 3 can rotate without wearing the yarn. The upper and lower guide rollers 3 can keep the height of the yarn on the base 1 unchanged.

[0024] Two electric cylinders 5 are installed on the surface of the base 1, and a cylinder shell 6 is installed on the upper end of the electric cylinder 5. A spring 14 and a push rod 10 located on the upper end of the spring 14 are placed inside the cylinder shell 6. The upper end of the push rod 10 is rotatably connected to a drum 9. The surface of the drum 9 is provided with a plurality of annular grooves 16, and the annular grooves 16 are used for limiting the position of the yarn. The spring 14 pushes the push rod 10 so that the drum 9 adjusts the tension of the yarn winding;

[0025] The electric cylinder 5 can be used to more conveniently adjust the height of the drum 9, and the spring 14 can move the push rod 10 up and down. When the yarn has a large tension, the yarn presses down the drum 9, and the drum 9 presses down the push rod 10 to move downward to avoid the yarn breaking.

[0026] In this embodiment, if Figure 4 As shown, a plurality of pulleys 4 are sleeved on the surface of the guide roller 3, and the upper and lower rows of pulleys 4 are aligned and arranged. The pulley 4 has a groove, and the yarn can be placed in the pulley 4. The pulley 4 is used to ensure that each yarn has a dedicated position to prevent the yarn from deviating.

[0027] In this embodiment, if Figure 3 As shown, three slide grooves 12 are provided on the surface of the push rod 10, and a plurality of universal beads 11 are installed on the surface of the cylinder shell 6, and the universal beads 11 are rollingly connected with the slide grooves 12, so as to improve the smoothness of the up and down movement of the push rod 10. When the yarn is taut, the push rod 10 can be smoothly pressed down to prevent the yarn from breaking.

[0028] In this embodiment, if Figure 1 , Figure 2 , Figure 3 As shown, a limit plate 13 is provided at the lower end of the push rod 10, and a baffle 7 is screwed on the upper surface of the cylinder shell 6. When the push rod 10 moves to the upper limit, the limit plate 13 is blocked by the baffle 7 to prevent the push rod 10 from separating from the cylinder shell 6.

[0029] In this embodiment, if Figure 1 As shown, a support seat 8 is installed at the upper end of the push rod 10, and the support seat 8 is rotatably connected to the roller 9. The support seat 8 supports the roller 9 and allows the roller 9 to rotate smoothly.

[0030] In this embodiment, if Figure 1 As shown, a cover 15 is provided at the lower end of the cylinder shell 6, and the cover 15 is connected to the electric cylinder 5. The cover 15 seals the lower end of the cylinder shell 6 and allows the cylinder shell 6 to be smoothly connected to the electric cylinder 5. The cover 15 supports the lower end of the spring 14.

[0031] Specifically, when in use, the yarn passes between the upper and lower pulleys 4, then winds around the annular groove 16 on the surface of the drum 9, and then passes through the two pulleys 4 on the other side. When the yarn is wound, the yarn has a certain downward pressure, the yarn presses down the drum 9 and causes the push rod 10 to move down, and the push rod 10 presses down the spring 14. When the yarn is relaxed, the spring 14 pushes the drum 9 upward through the push rod 10, and the drum 9 automatically tightens the yarn, thereby realizing automatic adjustment of the yarn tension. It is more convenient to adjust the yarn tension without manual adjustment. When the yarn is too relaxed, the electric cylinder 5 can also be used to control the drum 9 to move up to adjust the yarn tension.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
