[0002] The pay-off stand is a commonly used auxiliary device for wire drawing machines in the production of wires and cables. According to the diameter of the wire, the wire drawing machine is divided into: large drawing machine, medium drawing machine, small drawing machine, fine wire drawing machine, micro-fine wire drawing machine, etc. The pay-off stand of the medium drawing machine is mostly a fixed pay-off stand, which can only use a single station for pay-off at a time, and the pay-off efficiency is low. A multi-head medium drawing machine can have multiple incoming wires at the same time. For the more common four-head medium drawing machine, it can feed four wires at the same time. If the existing pay-off stand is used, four units need to be placed, which takes up a lot of space. The machine must be stopped when the pay-off frame is replaced, and the production fluency is poor. There are also discussions about the pay-off stand for medium drawing machines in the prior art, for example: "A pay-off stand for medium drawing machine" with publication number CN108516408A, "A pay-off stand for medium drawing machine" with announcement number CN202736592U, and "A pay-off stand for medium drawing machine" with announcement number CN201711384U, etc. These pay-off stands are mainly improved from the aspects of adapting to the requirements of operations at different heights and anti-winding, but do not consider meeting the simultaneous wire feeding requirements of multi-head medium drawing machines.

[0008] Each wire reversing system has a corresponding guide wheel for each wire wheel. The guide wheel is parallel to the rotation axis of the corresponding wire wheel. The guide wheel is connected to the frame and is located next to the unified wiring area. The path of any wire is from the wire wheel to the guide wheel via the steering wheel and then enters the unified wiring area. The paths of each wire in the unified wiring area are parallel to each other.

[0009] There are two multi-groove wheels at the end of the unified wiring area, the number of wheel grooves of the multi-groove wheels corresponds to the number of wire reversing systems, and the positions of the wheel grooves of the two multi-groove wheels correspond; the rotation axes of the two multi-groove wheels are parallel to the ground; the two multi-groove wheels are connected to the frame body one above and one below, the wheel groove positions of the upper multi-groove wheel correspond to each wire path in the unified wiring area, and the lower multi-groove wheel is the outlet wheel of the pay-off frame.

[0027] There is a unified wiring area 8 on the frame;

[0028] The wire wheel of any wire reversing system corresponds to a guide wheel 9, the guide wheel is parallel to the rotation axis of the corresponding wire wheel, the guide wheel is connected to the frame 1, and is located next to the unified wiring area 8; the path of any wire 10 is from the wire wheel to the guide wheel through the steering wheel, and then enters the unified wiring area; the paths of each wire in the unified wiring area are parallel to each other;

[0029] At the end of the unified wiring area 10, there are two multi-groove wheels 11, the number of wheel grooves of the multi-groove wheels corresponds to the number of wire reversing systems, and the positions of the wheel grooves of the two multi-groove wheels correspond; the rotation axes of the two multi-groove wheels are parallel to the ground; the two multi-groove wheels are connected to the frame body one above and one below, the wheel groove positions of the upper multi-groove wheel correspond to each wire path in the unified wiring area, and the lower multi-groove wheel is the outlet wheel of the pay-off frame.

[0030] One implementation of the rotation drive device is that the rotation drive device is a cylinder; the rear portion of the conversion rocker 7 is connected to the frame 1 through a bearing structure; the cylinder body 12 of the cylinder is rotationally connected to the frame 1, and the piston rod 13 of the cylinder is rotationally connected to the conversion rocker 7. This example is this method.

[0031] Another implementation of the rotation drive device is that the rotation drive device is an electric motor; the rear portion of the conversion rocker arm is connected to the frame through a bearing structure, the rotor of the electric motor is connected to the shaft of the bearing structure, and the body of the electric motor is connected to the frame.

[0032] Each position of the wire-laying frame 4 in the wire-laying frame placement area 3 corresponds to a workstation, and the stop position of the corresponding conversion rocker arm corresponds to the workstation, and the steering wheel is above the corresponding workstation.

[0033] The frame forms a rectangular structure; each conversion rocker 7 is connected to the opposite side of the top surface of the frame 1; the unified routing area 8 is located on the top surface of the frame, and the path of the wire 10 in the unified routing area is parallel to the side connected to the conversion rocker.

[0034] refer to Figure 5 Any wire reversing system has two wire passing wheels 5 in pairs, which are located on the top surface of the frame 1; the line between the axes of the wire passing wheels is perpendicular to the path of the wire 10 in the unified routing area 8; the guide wheel 9 corresponding to the wire passing wheel is located on the top surface of the frame, and the routing planes of the wire passing wheel and the guide wheel coincide, and the bottom of the wheel groove of the steering wheel 6 is on the routing plane of the wire passing wheel.

[0037] In this example, a ladder is connected to one end of the frame for ease of operation.

[0038] The operation method of the prior art is that when the wire in the pay-off frame is about to run out, the operator needs to stop the machine to move the pay-off frame out, then connect the wire to the wire in the full frame, and then move the full pay-off frame to the previous position. Since the positions of multiple pay-off frames are at different distances from the wire inlet end of the intermediate drawing machine, the time when the wire in each pay-off frame runs out is different, so multiple stops are required.

[0039] After using the utility model, the double workstations can be moved horizontally, and the operator can connect the wires in the wire-paying frame that is about to be exhausted to the wires in the full frame of the wire-paying frame of another workstation in advance. Even if the wires in the wire-paying frames are exhausted at different times, there is no need to stop the machine for multiple frame changes. It only needs to turn the conversion rocker to rotate the steering wheel to another workstation position.

[0040] The utility model has a simple structure: compared with the existing more complicated wire feeding method of the multi-head medium drawing machine, the wire pay-off frame can complete the direction conversion of the wire path only through the wire reversing system, and at the same time uses the conversion rocker of the wire reversing system to realize the conversion of the wire pay-off frame workstation.

[0041] The utility model is easy to use: compared with the complicated process in the prior art, the station conversion simplifies the process operation steps.

[0042] The utility model has high production efficiency: compared with the prior art in which the machine needs to be stopped every time a frame is changed, the use of the pay-off rack can ensure smooth production while changing the frame.
