Description

Technical Field

[0001] The utility model relates to the technical field of winding mechanisms, in particular to an adjustable winding mechanism for producing strapping tapes. Background Art

[0002] Strapping tape is a uniaxially oriented plastic strapping material, mainly used for cargo packaging, hot-rolled steel coil strapping, cold-rolled steel coil strapping, etc.

[0003] In the existing technology, strapping tape has the advantages of being light, strong, corrosion-resistant and easy to use. It is widely used in scenarios such as cargo transportation, packaging or bundling items. After the strapping tape is produced, it needs to be rolled up to facilitate subsequent storage and transportation.

[0004] However, during the process of winding the strapping tape, due to friction, the strapping tape is easily loosened due to insufficient tension during winding, resulting in the strapping tape being loose after winding, which is inconvenient to store and transport. Utility Model Content

[0022] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit 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.

[0023] See also Figures 1 to 5 The utility model provides a technical solution: an adjustable winding mechanism for producing strapping tape.

[0024] In embodiment 1, a rotating shaft 9 is movably provided on the inner surface of the winding bracket 1, a tensioning bracket 3 is fixed on the outer surface of the rotating shaft 9, a roller 17 is movably provided on the outer surface of the tensioning bracket 3, a winding roller 4 is fixed on the inner surface of the rear end of the winding bracket 1, and a strapping tape 2 is sleeved on the outer surface of the winding roller 4. The two groups of tensioning brackets 3 rotate clockwise, so that one group of tensioning brackets 3 is raised in height and the other group of tensioning brackets 3 is lowered in height, so that the vertical distance between the strapping tapes 2 on the two groups of surfaces becomes larger, thereby changing the tension of the strapping tape 2 and making the strapping tape 2 tighter.

[0025] A handwheel 5 is fixed to the end of the gear 7. The clockwise rotation of the gear 7 will drive the two sets of tensioning brackets 3 to rotate clockwise. A limit rod 11 is provided on the side of the gear 7. A spring 10 is sleeved on the outer surface of the limit rod 11. Due to the elasticity of the spring 10, the spring 10 will push the limit rod 11 through the baffle 16 to be clamped into the tooth groove of the gear 7.

[0026] On the basis of Example 1, in order to adjust the tension of the strapping tape 2 during winding, a support plate 14 is fixed to the outer surface of the winding bracket 1, and a limit rod 11 is movably inserted inside the support plate 14. There are two groups of support plates 14, and the spring 10 is sleeved on the outer surface of the limit rod 11 between the two groups of support plates 14.

[0027] A first curved surface 6 is provided on the side surface of the gear 7 , and a second curved surface 15 is provided on the side surface of the end portion of the limiting rod 11 . The first curved surface 6 corresponds to the second curved surface 15 . A baffle 16 is fixed on the outer surface of the limiting rod 11 , and the baffle 16 is located between the two sets of support plates 14 .

[0028] A gear 7 is fixed to the end of the rotating shaft 9, an annular block 8 is fixed to the outer surface of the rotating shaft 9, a positioning hole 12 is opened on the side surface of the winding bracket 1, the positioning hole 12 penetrates the winding bracket 1, and an annular groove 13 is opened on the inner wall of the positioning hole 12.

[0029] The rotating shaft 9 corresponds to the positioning hole 12 and is clamped, and is movably connected. The annular block 8 corresponds to the annular groove 13 and is clamped, and is movably connected. On the one hand, the rotating shaft 9 and the winding bracket 1 are movably connected. On the other hand, it plays a positioning role for the rotating shaft 9 to prevent the rotating shaft 9 from deflecting when rotating.

[0030] The tensioning bracket 3 is located on the inner surface of the winding bracket 1 in front of the winding roller 4. There are two groups of tensioning brackets 3. The two groups of tensioning brackets 3 are movably connected. The angle between the two groups of tensioning brackets 3 is an obtuse angle, and the angle between the two groups of tensioning brackets 3 is smaller than a straight angle.

[0031] When the strapping belt 2 is loosened due to the friction of long-term use, the hand wheel 5 can be used to drive the gear 7 to rotate. Since the surfaces of the gear 7 and the limit rod 11 are curved when the gear 7 rotates clockwise, and the two sets of curved surfaces correspond to each other, the gear 7 will not be affected by the limit rod 11 when it rotates clockwise, and the gear 7 will be restricted by the limit rod 11 and cannot rotate when it rotates counterclockwise because the surface corresponding to the limit rod 11 is a plane. Therefore, the clockwise rotation of the gear 7 will drive the two sets of tensioning brackets 3 to rotate clockwise, so that the height of one set of tensioning brackets 3 is increased and the height of the other set of tensioning brackets 3 is decreased, so that the vertical distance between the strapping belts 2 on the two surfaces is increased, thereby changing the tension of the strapping belt 2, making the strapping belt 2 tighter, and preventing the strapping belt 2 from becoming loose, thereby realizing the adjustment of the tension of the strapping belt 2 when it is rolled up.

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