Description

Technical Field

[0001] This utility model relates to the field of material strip winding technology, and in particular to a rotary tensioning and unwinding device. Background Technology

[0002] CN119409028B discloses a high-strength steel winding drum, which is driven by a lead screw. However, the adjustable range of this drum structure is small, and it is not easy to separate from the wound steel strip after winding. CN115535733A discloses a turntable mechanism with an adjustable inner diameter, which adopts a six-support structure. However, the overall structural support strength is small, and it is not stable when supporting the drum, especially in resisting the torque.

[0003] No existing technology has found a winding / unwinding device that can provide stable support for the drum and adjust the tension. Utility Model Content

[0004] The technical problem to be solved by this utility model embodiment is to provide a rotary tensioning and unloading device to solve the problem of drum support and tension adjustment.

[0005] To solve the above-mentioned technical problems, this utility model provides a rotary tensioning and feeding device, including: a support plate (10), a base (20), an adjusting screw (30), an adjusting sleeve (40), and multiple sets of telescopic tensioning modules (50) connected between the adjusting sleeve (40) and the support plate (10), wherein: the base (20) is fixedly installed at the center of the lower surface of the support plate (10), the adjusting screw (30) is installed in the base (20) and passes vertically through the center of the support plate (10); the adjusting sleeve (40) is connected to the adjusting screw (30); the telescopic tensioning module (50) includes two parallel connecting rods (51), a push rod (52) arranged parallel to the adjusting screw (30), a clamping roller (53) connected to the bottom of the push rod and clamping the support plate (10) from both sides, and a tensioning block (54) fixedly connected to the outside of the push rod; a radial groove (11) is provided on the support plate (10) corresponding to each push rod (52).

[0006] An adjustment handle (31) is provided on the top of the adjusting screw (30) to control the rotation of the adjusting screw (30).

[0007] The base (20) is connected to the adjusting screw (30) via a bearing.

[0008] The telescopic tensioning module (50) consists of 3-6 groups, which are evenly distributed around the adjusting screw (30) in the circumference; correspondingly, each group of telescopic tensioning module (50) is provided with a radial groove on the support plate (10).

[0009] The base (20) also serves as a driven structure, and by applying external steering assistance, the base (20) drives the supporting flower plate (10) to rotate.

[0010] One end of the connecting rod (51) is rotatably connected to the hinge seat on the adjusting sleeve (40), and the other end is rotatably connected to the push rod (52) through a pin; the two connecting rods (51) are connected in parallel between the adjusting sleeve (40) and the push rod (52).

[0011] The rotary tensioning winding and unwinding device provided by this utility model uses a support disc as the main bearing platform for the material roll. The telescopic tensioning module expands the roll from the inside out, achieving a tensioning effect. Simultaneously, the clamping rollers of the telescopic tensioning module move along the radial groove on the support disc with the push rod. The clamping rollers limit the bottom of the push rod, ensuring it can only move horizontally along the radial groove. The adjusting screw drives the adjusting sleeve, causing it to move up or down, thus controlling the radial tensioning position of the push rod. Due to the clamping roller structure, the tensioning block on the outside of the push rod, after supporting the roll, maintains a fixed position between the roll and the support disc, resulting in more stable winding or output of the material roll.

[0018] like Figure 1-2 As shown, this utility model provides a rotary tensioning and unloading device, including: a support disc 10, a base 20, an adjusting screw 30, an adjusting sleeve 40, and multiple sets of telescopic tensioning modules 50 connected between the adjusting sleeve 40 and the support disc 10. The base 20 is fixedly installed at the center of the lower surface of the support disc 10; the adjusting screw 30 is installed in the base 20 and passes vertically through the center of the support disc 10; the adjusting sleeve 40 is fitted onto the adjusting screw 30; the telescopic tensioning module 50 includes two parallel connecting rods 51, a push rod 52 arranged parallel to the adjusting screw 30, clamping rollers 53 connected to the bottom of the push rod and clamping the support disc 10 from both sides, and a tensioning block 54 fixedly connected to the outside of the push rod; a radial groove 11 is provided on the support disc 10 corresponding to each push rod 52.

[0019] The support disc 10 is a disc structure with a certain rigidity, used to carry the material roll and wind or output the material roll. The center of the support disc 10 is provided with a central hole for adjusting the lead screw 30 to pass through. The support disc 10 is provided with a radial groove 11 for each set of telescopic tensioning modules 50. The radial groove 11 is a straight groove structure. The two sides of the radial groove 11 are used to clamp the roller 53 for clamping and supporting. The base 20 is a cylindrical structure with bearings installed inside to facilitate the connection of the adjusting screw 30; the upper part of the base 20 is connected to the lower surface of the support plate 10 by screws; the base 20 is fixedly connected to the center hole of the support plate 20. The bottom of the adjusting screw 30 is rotatably connected to the base 20, and the adjusting screw 30 is perpendicular to the supporting flower plate 10. The adjusting sleeve 40 has a certain length, which can meet the connection requirements of the two connecting rods 51. The adjusting sleeve 40 and the adjusting screw 30 are rotated together by a threaded pair. The telescopic tensioning module 50 drives the adjusting sleeve 40 through the adjusting screw 30, thereby causing the parallelogram connecting rod to change its tilt direction, and thus adjusting the radial position of the push rod 52 to achieve the function of controlling tension.

[0020] An adjusting handle 31 is provided on the top of the adjusting screw 30 to control the rotation of the adjusting screw 30.

[0021] The base 20 is connected to the adjusting screw 30 via bearings.

[0022] The telescopic tensioning module 50 consists of 3-6 groups, which are evenly distributed around the adjusting screw 30 in the circumference; correspondingly, each group of telescopic tensioning modules 50 is provided with a radial groove on the supporting disc 10.

[0023] The base 20 also serves as a driven structure, and by applying external steering assistance, the base 20 drives the supporting flower plate 10 to rotate.

[0024] One end of the connecting rod 51 is rotatably connected to the hinge seat on the adjusting sleeve 40, and the other end is rotatably connected to the push rod 52 via a pin; the two connecting rods 51 are connected in parallel between the adjusting sleeve 40 and the push rod 52.

[0025] The rotary tensioning winding and unwinding device provided by this utility model uses a support disc as the main bearing platform for the material roll. The telescopic tensioning module expands the roll from the inside out, achieving a tensioning effect. Simultaneously, the clamping rollers of the telescopic tensioning module move along the radial groove on the support disc with the push rod. The clamping rollers limit the bottom of the push rod, ensuring it can only move horizontally along the radial groove. The adjusting screw drives the adjusting sleeve, causing it to move up or down, thus controlling the radial tensioning position of the push rod. Due to the clamping roller structure, the tensioning block on the outside of the push rod, after supporting the roll, maintains a fixed position between the roll and the support disc, resulting in more stable winding or output of the material roll.

[0026] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0027] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
