Description

Technical Field

[0001] The utility model relates to the technical field of cable processing, in particular to a wrapping device with adaptively adjustable wrapping angle. Background Art

[0002] During the cable production process, the cables need to be wrapped so that the cables can obtain corresponding performance according to the different wrapping materials.

[0003] During wrapping, the wrapping machine's annular disc is driven to rotate at high speed, causing the coil of wrapping material on the disc to be wound around the cable passing through the center of the disc. Before wrapping, the wrapping angle must be adjusted—that is, the angle of the annular disc relative to the radial plane of the cable. The tightening force of the wrapping material on the cable is closely related to the wrapping angle. Specifically, as the wrapping angle increases, the radial force of the wrapping material decreases, and the tightening force on the cable also decreases. However, the wrapping speed increases, and the amount of wrapping material used decreases.

[0004] In order to ensure that the wrapping material can wrap the cable tightly at the initial stage of wrapping and ensure the normal progress of subsequent wrapping, the cable is usually wrapped at a smaller wrapping angle at the initial stage of wrapping. However, the adjustment of the wrapping angle during the wrapping process currently requires driving components such as cylinders, electric push rods, and motors. The annular disc rotates at high speed during wrapping, which is prone to changes in the wrapping angle due to fatigue failure of the driving components. The reliability is poor, and the hardware cost and energy consumption are high. Utility Model Content

[0005] The purpose of the utility model is to provide a wrapping device with adaptively adjustable wrapping angle to solve the above technical problems.

[0006] Based on the above objectives, the utility model provides a wrapping device with adaptive wrapping angle adjustment, comprising a wrapping disc and a tape roll, an adjustment arm, a diagonal support arm, and a cylindrical tension spring, wherein the proximal end of the adjustment arm is hinged to the wrapping disc, and the tape roll is rotatably arranged on the side of the distal end of the adjustment arm via a rotating shaft;

[0007] The two ends of the cylindrical tension spring are respectively connected to the diagonal support arm and the wrapping disk; a sliding pin is provided on the adjustment arm for sliding along the length direction; one end of the diagonal support arm is hinged to the wrapping disk, and the other end is connected to the sliding pin;

[0008] The adjusting arm rotates outward by utilizing the centrifugal force generated by the rotation of the wrapping disk, so that the angle of the tape roll relative to the radial plane of the cable increases to a set wrapping angle;

[0009] The cylindrical tension spring is used to drive the adjustment arm to reset, so that the tape roll wraps the cable at an initial wrapping angle smaller than the set wrapping angle at the initial wrapping stage.

[0010] Furthermore, a slider is slidably provided on the adjusting arm along the length direction, the slider is fixed to the adjusting arm via a coarse adjustment bolt, and a plurality of coarse adjustment positioning holes are provided on the adjusting arm along the length direction.

[0011] Furthermore, the adjusting arm is provided with a T-shaped slide rail, the sliding block is provided with a T-shaped slide groove matching the T-shaped slide rail, and the coarse adjustment positioning hole passes through the T-shaped slide rail.

[0013] Furthermore, threaded holes communicating with the sliding hole are provided at both ends of the slider, and fine-tuning bolts are provided in the threaded holes.

[0014] Beneficial effects of the utility model:

[0015] The utility model utilizes the centrifugal force generated by the adjustment arm rotating with the wrapping disk to gradually increase the angle of the adjustment arm to the standard wrapping angle in the initial stage of wrapping. The cylindrical tension spring drives the adjustment arm to reset with the help of the diagonal support arm and the sliding pin, so that the tape roll wraps the cable at an initial wrapping angle smaller than the standard wrapping angle in the initial stage of wrapping, thereby facilitating the tight wrapping of the cable by the wrapping material in the initial stage of wrapping.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figures 1 to 4 As shown, a wrapping device with adaptive wrapping angle adjustment includes a wrapping drum 1 and a tape roll 2, an adjustment arm 3, a diagonal support arm 4, and a cylindrical tension spring 5. The proximal end of the adjustment arm 3 is hinged to the wrapping drum 1, and the tape roll 2 is rotatably arranged on the side of the distal end of the adjustment arm 3 via a rotating shaft;

[0025] The two ends of the cylindrical tension spring 5 are respectively connected to the diagonal support arm 4 and the wrapping disc 1. A sliding pin 6 is provided on the adjusting arm 3 so as to slide along the length direction. One end of the diagonal support arm 4 is hinged to the wrapping disc 1, and the other end is connected to the sliding pin 6.

[0026] The adjusting arm 3 rotates outwards by utilizing the centrifugal force generated by the rotation of the wrapping drum 1, so that the angle of the tape roll 2 relative to the radial plane of the cable increases to the standard wrapping angle;

[0027] The cylindrical tension spring 5 is used to drive the adjustment arm 3 to reset, so that the tape reel 2 wraps the cable at an initial wrapping angle smaller than the standard wrapping angle at the beginning of the wrapping process. This increases the radial force of the wrapping material on the cable during the initial wrapping process, facilitating the wrapping of the cable tightly and ensuring the normal wrapping process. This helps to avoid the situation where the wrapping material and the cable slip relative to each other during the subsequent wrapping process due to insufficient tightening force during the initial wrapping process, resulting in substandard wrapping quality.

[0028] It is particularly noted that although the diagonal bracing arm 4 can use drive components such as a cylinder or electric push rod to achieve automated control and adjustment of the angles of the adjustment arm 3 and the belt roll 2, the centrifugal force received by the distal end of the adjustment arm 3, where the belt roll 2 is located, is relatively large when the adjustment arm 3 rotates around the wrap 1, placing high demands on the tensile strength of the cylinder and electric push rod. As the centrifugal force on the slider 13 increases, the friction between it and the adjustment arm 3 also increases accordingly. Therefore, in subsequent optimization, the slider 13 can be driven by a drive component such as a cylinder or electric push rod provided on the adjustment arm 3. This is not only reliable and stable, but also places lower demands on the drive components.

[0029] A slider 13 is provided along the length of the adjustment arm 3 for sliding movement. The slider 13 is secured to the adjustment arm 3 via a coarse adjustment bolt 7. Multiple coarse adjustment positioning holes 8 are provided along the length of the adjustment arm 3 to enable preliminary adjustment of the wrapping angle. A T-shaped slide rail 9 is provided on the adjustment arm 3, and the slider 13 is provided with a T-shaped slot 10 that mates with the T-shaped slide rail 9. The coarse adjustment positioning holes 8 extend through the T-shaped slide rail 9, connecting the coarse adjustment bolt 7 to the T-shaped slide rail 9 to secure the slider 13.

[0030] To further fine-tune the wrapping angle, the slider 13 is provided with sliding holes 11 running through both sides along the length of the adjustment arm 3. The sliding pin 6 is slidably engaged with the sliding holes 11, and diagonal bracing arms 4 are provided at both ends of the sliding pin 6 to facilitate stable sliding of the sliding pin 6 relative to the slider 13. Furthermore, both ends of the slider 13 are provided with threaded holes communicating with the sliding holes 11. Fine-tuning bolts 12 are provided in these threaded holes. The fine-tuning bolts 12 are used to adjust the travel endpoints of the sliding pin 6 at both ends, thereby fine-tuning the angle of the adjustment arm 3 and, in other words, fine-tuning the initial wrapping angle and the standard wrapping angle.

[0031] It is understood from common technical knowledge that the present invention may be implemented through other embodiments that do not depart from its spirit or essential features. Therefore, the embodiments disclosed above are, in all respects, merely illustrative and not exclusive. All modifications within the scope of the present invention or equivalent to the scope of the present invention are intended to be encompassed by the present invention.
