Description

Technical Field

[0001] The utility model relates to the technical field of wrapping equipment, in particular to a tension-controllable paper tape pay-out module, a cable wrapping device and a wrapping system. Background Art

[0002] In the production process of (paper) insulated leads for high-voltage electrical equipment, wrapping equipment plays a vital role. Wrapping equipment, also known as a tape wrapping machine or a film wrapping machine, is a device that rotates the tape / insulating film on a turntable and wraps it around the cable. It is mainly used for wrapping the insulating core wires of electric wires, power cables, control cables, optical cables, etc., and plays a role in electrical shielding and protective molding for the cables. At present, compared with manual wrapping or semi-automatic insulation material wrapping, mechanical wrapping tension is more controllable, the misalignment, gap, and overlap between insulation paper layers are more controllable, and the thickness of the insulation wrapping is more uniform, which not only improves production efficiency, but also improves the insulation performance of the product.

[0003] In the actual production process, the paper tray of the paper wrapping machine must release the paper under tension, and this damping is mainly controlled by the size of the torque. As the paper tape is consumed, the outer diameter of the paper tape becomes smaller and smaller. If the damping torque remains unchanged, the tension of the paper tape becomes larger and larger. For the product, the paper will be wrapped tighter and tighter, which will reduce the softness, so it is necessary to try to adjust the size of the damping torque. When the paper tape is affected by the wrapping speed, the tightness of the paper ring, etc., the tension is unstable during release, which can easily cause wrinkles or breakage of the paper tape on the conductor. Therefore, the wrapping equipment still needs to be improved to achieve the technical effect of "constant tension for paper release" and real-time adjustable tension.

[0004] Among the existing wrapping equipment, the initial tension of the semi-tangent wrapping equipment is adjustable but not variable; the flat wrapping equipment has a simple structure but the tension is not adjustable; the concentric wrapping equipment has a fast speed and the tension changes automatically according to the size of the paper tray, but one wrapping equipment can only wrap one layer of paper and is not suitable for multi-layer wrapping. Therefore, the existing wrapping equipment often cannot solve the problems of real-time tension adjustment and multi-layer wrapping at the same time, and a new type of wrapping equipment and wrapping process is still to be developed.

[0036] Embodiment 1:

[0037] This embodiment provides a tension-controllable paper tape pay-out module, including a paper tape pay-out component 11 and a tension control component 12 .

[0038] The paper tape unwinding assembly 11 comprises a paper tray loading frame 111 , and a paper tray 112 to be loaded with paper is installed on a paper tray fixing shaft 113 on the paper tray loading frame 111 .

[0039] The tension control assembly 12 includes a tension adjustment brake 121, a swing roller 122 and a damping wheel 123. The tension adjustment brake 121 is installed on the paper tray fixed shaft 113. An adjustment screw rod 124 is connected between the tension adjustment brake 121 and the swingable swing roller 122.

[0040] After the paper tape on the paper tray 112 is released, it passes through the swing roller 122 and the damping wheel 123 and is wrapped around the cable. When the tension of the paper tape changes, the damping wheel 123 plays a certain buffering role, the swing roller 122 swings and drives the adjusting screw 124 to move, and the adjusting screw 124 transmits force to the tension adjustment brake 121 to play a role in fine-tuning the tension, so that the tension of the paper tape is constant, and the tension changes in real time, that is, the purpose of constant tension.

[0041] Embodiment 2:

[0042] A tension-controllable paper tape pay-out module comprises a paper tape pay-out component 11 and a tension control component 12.

The paper tape discharging assembly 11 of this embodiment also includes a fastening handle 115, which is fixedly connected to a connecting shaft, and the other end of the connecting shaft passing through the axial direction of the paper tray fixing shaft 113 is locked by a locking nut 116 to fix and install the paper tray 112. When the paper tray 112 is initially installed, the paper tray 112 can be clamped only between the leaf plates by the fastening handle 115 and the locking nut 116.

[0044] The tension control assembly 12 includes a tension adjustment brake 121, a swing roller 122 and a damping wheel 123, and the tension adjustment brake 121 is installed on the paper tray fixed shaft 113.

The rotating shaft is connected to the electric drive device. The cable wound on the pay-off drum is input into the wrapping device 1. The traction device 3 is a crawler traction device. The wrapped cable is input between the upper crawler and the lower crawler and then enters the take-up device 4. The take-up device 4 includes a take-up frame and a take-up drum. The take-up drum is fixedly mounted on the rotating shaft between the two side walls of the take-up frame. The rotating shaft is connected to the electric drive device. The cable to be taken up is wound on the take-up drum.

[0054] First, the insulating paper tray 112 is sleeved on the tray fixing shaft 113 and clamped by the leaf plates 114 on both sides, and the tightening handle 115 is turned to fix the tray 112. Then, the tension adjustment brake 121 is adjusted until the paper tape initially released meets the wrapping requirements.

The cable wound on the pay-off reel is input into the cable wrapping device 1; under the rotation of the wrapping head 13, the paper tapes on the multiple paper trays 112 are respectively wrapped around the cable through the regulation of the swing roller 122 and the damping wheel 123 to form a multi-layer wrap; the wrapped cable is input between the upper and lower crawler tracks of the traction device 3, and after the wire diameter is controlled, it is input into the take-up device 4 and wound on the take-up reel.

[0056] As the paper tape on the paper tray 112 is consumed, the tension of the paper tape will gradually increase. At this time, the damping wheel 123 plays a certain buffering role, the swing roller 122 swings and drives the adjusting screw 124 to move, and the adjusting screw 124 transmits force to the tension adjustment brake 121 to play a role in fine-tuning the tension, so that the paper tape is released with constant tension, achieving the purpose of real-time tension change, that is, constant tension.

[0057] Based on the above-mentioned tension-controllable cable wrapping system, the whole process of cable unwinding-wrapping-pulling-winding can be realized, the cable can be wrapped with multiple layers of insulating materials, and the tension of the paper tape can be adjusted in real time.
