Description

Technical Field

[0001] The utility model relates to the technical field of packaging and winding, in particular to a bag belt pull-back buffer device. Background Art

[0002] During the processing of metal core coils, a taping machine is usually required to wrap the metal core coils with insulating tape. A gear-type annular taping machine is usually equipped with a taping ring, also known as a storage ring, which stores insulating tape. During processing, the taping ring is driven to rotate by the power mechanism on the taping machine, thereby wrapping the insulating tape around the outside of the metal core coil. When winding multiple layers of insulating tape, the issue of insulating tape tension needs to be addressed. Existing taping machines mainly adjust the tension through belt friction, but the tightness of the belt is difficult to confirm during the winding process. Especially when there are too many layers of tape storage, if the belt friction is too great, the insulating tape cannot be pulled out from the bottom, resulting in the problem of insulating tape breakage.

DETAILED DESCRIPTION

[0025] The technical solution of the present utility model is further described below through the accompanying drawings and embodiments.

[0026] Combine Figures 1 to 8 , this embodiment provides a wrapping tape pullback buffer device, which is installed on the wrapping tape ring 1 and includes a slider mounting bar 2, the slider mounting bar 2 is fixedly mounted on the side of the wrapping tape ring 1, and a slide groove 21 is provided on the slider mounting bar 2, in which a pullback slider 31 assembly 3 is slidably connected, and a tension spring 4 is provided between the pullback slider 31 assembly 3 and the end of the slide groove 21, and a fixed shaft block 5 is fixedly provided on the end of the slider mounting bar 2 away from the tension spring 4, and a pullback fixed shaft 6 is installed on the fixed shaft block 5, and a pullback movable shaft 7 is installed on the pullback slider 31 assembly 3. After the insulating tape 11 in the wrapping tape ring 1 is pulled out, it passes around the pullback fixed shaft 6 and the pullback movable shaft 7 in turn, and is wound around the outside of the metal core coil 8.

[0027] In this embodiment, the pull-back fixed shaft 6 and the pull-back movable shaft 7 are both located on the inner side of the tape ring 1 .

[0028] In this embodiment, the slider mounting bar 2 is an arc-shaped plate structure, and the center of the arc of the arc-shaped plate coincides with the center of the band ring 1 .

[0029] In this embodiment, a groove 22 is further provided on the slider mounting bar 2 , one end of the tension spring 4 is fixedly connected in the groove 22 , and the other end extends to the outside of the groove 22 and is located in the slide groove 21 .

[0030] In this embodiment, the pulling-back slider 31 assembly 3 includes a pulling-back slider 31, a slider shaft 32 and a roller 33. The roller 33 is rotatably sleeved on the outside of the slider shaft 32 and slidably set in the slide groove 21. The top end of the slider shaft 32 is fixedly installed on the pulling-back slider 31, and the pulling-back slider 31 is connected to the pulling-back movable shaft 7.

[0031] In a further embodiment, the pull-back slider 31 is a T-shaped structure, which includes a vertically connected transverse portion 311 and a vertical portion 312. The transverse portion 311 is located above the slide groove 21. The number of the slider shafts 32 is two, and the two slider shafts 32 are respectively located near the two ends of the transverse portion 311.

[0032] In a further embodiment, the pull-back movable shaft 7 is connected to the vertical portion 312 via a bearing, and the pull-back fixed shaft 6 is fixedly mounted on the fixed shaft block 5 .

[0033] In this embodiment, an upper pressing bar 23 and a lower pressing bar 24 are further provided on the slider mounting bar 2 . Both the upper pressing bar 23 and the lower pressing bar 24 are located above the sliding groove 21 and are used to limit the roller 33 .

[0035] In this embodiment, the metal core coil 8 is an iron core.

[0036] During operation, the insulating tape 11 is pulled out from the wrapping ring 1, first passing through the retraction fixed shaft 6 and then the retraction movable shaft 7. When winding the product, the retraction fixed shaft 6 will first pass through the iron core. Since the insulating tape 11 is blocked and the retraction movable shaft 7 moves in the opposite direction of winding, the tension of the insulating tape 11 is maximum and it is easy to break. In this process, the retraction movable shaft 7 plays a buffering role in releasing the tension and preventing the insulating tape 11 from breaking. When the wrapping ring 1 continues to rotate, the length of the pulled insulating tape 11 has reached the maximum, and the retraction movable shaft 7 also reaches the limit position. At this time, the tension spring 4 retracts the retraction movable shaft 7 and tightens the insulating tape 11 at the same time.
