technical field

The application relates to a pull-type pay-off frame, which belongs to the field of wire rod production equipment.

Background technique

In the process of wire rod processing, it needs to go through multiple processes, such as wire laying, shelling, drawing, etc. At present, the pay-off equipment such as the duckbill pay-off rack used by most wire rod production enterprises is mostly simple in structure. During production, the wire is sent out from the pay-off rack by the traction motor. , if the traction motor cannot be stopped in time, the wire will continue to be pulled by the traction motor, causing the wire to be forcibly pulled, or even broken. When this happens, the operator has to stop and rewire, which takes a long time and reduces the production efficiency of the entire production line. Secondly, when using traditional pay-off equipment, there are many friction points between the wire and the pay-off frame and the ground, which not only generates considerable noise and vibration, but also causes serious wear on the surface of the wire, which affects subsequent processes and reduces the quality of wire processing. Thirdly, when the traditional pay-off equipment is used, a large area of the wire is exposed in the workshop, and the horizontal footprint is large, which not only wastes space, but also poses a threat to the personal safety of the operator, with a low safety factor.

Although the pay-off equipment provided by the prior art solves some of the above-mentioned problems, it cannot completely solve the above-mentioned technical problems. Therefore, it is necessary to design a new type of pay-off equipment to solve the above problems.

During the wire-releasing process, the wire 1 is pulled by the external traction motor 4 to bypass the first wire-releasing guide wheel 21 , the second wire-releasing guide wheel 22 , and the buffer guide wheel 32 in sequence. During the wire-releasing process, the buffer guide wheel mounting seat 31 maintains a force balance under the pulling force of the wire rod and the pulling force of the counterweight 34 . The displacement sensor 35 is connected with the controller of the traction motor 4 .

During the unwinding process, when the wire is knotted due to disordered wires, the buffer guide wheel mounting seat 31 equipped with the buffer guide wheel 32 will move downward as a whole under the tension of the wire rod, and at the same time, the buffer guide wheel mounting seat 31 will pass through the first The suspension rope 36 drives the counterweight 34 to move upwards; if the wire is slightly knotted, the above-mentioned pulling process can pull the knot apart, and the buffer block 34 will reset after rising to a small height, and the wire will not be over-drawn.

When the knotting was severe, the counterweight 34 rose to a higher height, and when reaching the corresponding height set, the displacement sensor 35 sent the displacement information to the controller of the traction motor 4, and the controller would stop the traction motor 4 to prevent Wire is over-drawn. After knotting the problem, restart the traction motor 4 and get final product.

Concretely, when there is a knotting phenomenon in the pay-off process, the wire rod is piled up on the wire inlet of the first pay-off guide wheel 21, and cannot be pulled out smoothly from the first pay-off guide wheel 21, and the traction motor 4 continues to pull the wire rod, so The buffer guide wheel mounting base 31 will move downward as a whole under the action of the tension of the wire rod, and will drive the counterweight 34 to move upward through the first suspension rope 36 at the same time. When the controller of the traction motor 4 receives the rising displacement of the counterweight 34 is small, the traction motor 4 stops slowly; pull.

In the above process, regardless of whether the wire is knotted slightly or severely, the process of the buffer guide wheel mounting seat 31 descending under the tension of the wire will buffer the force of the wire being pulled, unlike the traditional pay-off equipment when the wire is knotted.
