Problems solved by technology
The situation that the existing packing tape unwinding equipment occurs in use is that when it is necessary to stop unwinding, the tape reel will rotate further due to the inertia of the rotation of the winding rotating shaft, and the length of unwinding tape cannot be well controlled. There is an excess of tapes, causing the tapes to be messy and affecting the subsequent packaging efficiency

The invention discloses a packing belt unwinding device which comprises a rack, a belt unwinding structure and an unwinding brake structure, the rack comprises two vertical rods and a cross rod connected between the two vertical rods, the belt unwinding structure comprises a center shaft, a rotating drum and a retaining frame, the center shaft is vertically and fixedly arranged on the cross rod, the rotating drum is arranged on the center shaft in a sleeving mode, the retaining frame is installed on the center shaft, and the unwinding brake structure is arranged on the rotating drum. The unwinding brake structure comprises a swing rod, a stop block and a spring, one end of the swing rod is hinged to the cross rod, the other end of the swing rod is provided with a belt hanging structure, the stop block is fixedly arranged on the swing rod and abuts against the rotary drum, one end of the spring is connected to the rack, and the other end of the spring is connected to the swing rod. And when traction is stopped by external force, the swing rod is reset under the action of elastic force, the stop block is pressed against the peripheral side of the rotary drum, and belt releasing is stopped. According to the invention, tape releasing can be stopped immediately as required, and the tape releasing length can be accurately controlled.
Description
technical field [0001] The invention relates to packing equipment, in particular to a packing tape unwinding device. Background technique [0002] After the steel strip is processed, it is rolled into a steel coil, and the steel coil needs to be wrapped with a packing belt before delivery to prevent the steel coil from loosening. When the packing tape is packed, the packing tape roll is released by the packing tape unwinding device. The packing tape unwinding device generally pulls one end of the tape body by traction, and the packing tape is wound around the rotating shaft to rotate and release the tape. The situation that the existing packing tape unwinding equipment occurs in use is that when it is necessary to stop unwinding, the tape reel will rotate further due to the inertia of the rotation of the winding rotating shaft, and the length of unwinding tape cannot be well controlled. There is an excess of tapes, resulting in messy tapes and rolls, which affects the subse...
