[0036] Please also read Figures 1 to 3 , the cable copper tape wrapping machine provided in the embodiment of the present application is now described. A cable copper tape wrapping machine includes a base, a tape winding frame, a driving synchronous pulley, a copper tape fixing seat, a magnetic powder brake and a plurality of elastic pressure plates. The base has an outer sleeve and a core tube inserted in the outer sleeve, and the outer sleeve and the core tube are independently arranged to rotate circumferentially, and the inside of the core tube is suitable for the cable to pass through; the tape winding frame is arranged at the front end of the outer sleeve; the driving synchronous pulley is arranged at the rear end of the outer sleeve, suitable for connecting with the power unit through a synchronous belt; the copper tape fixing seat is arranged at the front end of the core tube; the magnetic powder brake is connected to the rear end of the core tube, and applies rotational resistance to the rear end of the core tube; a plurality of elastic pressure plates are distributed around the front end of the core tube, and the wire core passing through the front end of the core tube is gathered to the middle.

[0037] Compared with the prior art, the cable copper tape wrapping machine of the embodiment of the present application has an outer sleeve and a core tube installed on the base, and the external power unit drives the outer sleeve to rotate by driving the synchronous pulley, so that the winding frame follows the rotation and winds the copper tape on the copper tape fixing seat around the wire core passing through the core tube; the magnetic powder brake provides rotation resistance for the core tube, so that the copper tape fixing seat has a certain rotation resistance, and when the copper tape on the copper tape fixing seat is pulled out by the winding frame, the copper tape will maintain a certain tension;

[0038] By using the magnetic powder brake, the resistance of the magnetic powder brake can be adjusted directly through the control signal, so the tension of the copper strip can be adjusted without stopping the machine; and the magnetic powder brake can also control the tension of the copper strip more accurately and stably, thereby improving product quality;

[0039] A plurality of elastic pressure plates are arranged around the front end of the core tube, which can gather the wire core passing through the front end of the core tube to the middle, reduce the shaking of the wire core during the winding process of the copper tape, and avoid friction between the wire core and the core tube.

[0040] In specific implementation, the base can be welded with steel plates to support and fix the outer sleeve and the core tube, so that the wire core after the previous merger can pass through the core tube. The specific form of the winding frame can refer to the common structure on the market, and will not be described in detail here. Its main function is to guide the copper belt so that the copper belt will not bend excessively and can pass smoothly during the process from the copper belt fixing seat to the winding on the wire core.

[0041] The external power unit is connected to the driving synchronous pulley through the driving synchronous belt, so that the outer sleeve and the belt winding frame can be driven to rotate together through the driving synchronous pulley.

[0042] The copper strip fixing seat is mainly used to fix the copper strip roll at the front end of the core tube. The specific structure can refer to the conventional reel structure for fixing the copper strip roll. Specifically, the copper strip fixing seat can be a sleeve with a limit plate at one end. The copper strip roll can be sleeved on the sleeve, and the limit plate is used for axial limit, and finally the copper strip roll is fixed to the sleeve with screws.

[0043] The present application uses a magnetic powder brake to provide resistance for the core tube to control the tension of the copper strip, thereby making the adjustment of the tension more convenient. The magnetic powder brake is a device disclosed in the prior art, which transmits torque based on the electromagnetic principle and uses magnetic powder, and can accurately control the magnitude of the torque by changing the magnitude of the excitation current.

[0044] The elastic pressure plate is used to gather the wire core to the middle, which can buffer the vibration of the wire core, keep the wire core stable, facilitate the winding of the copper strip, and prevent the wire core from contacting the tube wall of the core tube and scratching the wire core. In specific implementation, the shape of the elastic pressure plate is similar to a fan shape, and there is a certain overlap between adjacent elastic pressure plates.

[0045] See also Figure 1 , as a specific embodiment of the cable copper tape wrapping machine provided by the present application, the cable copper tape wrapping machine also includes a tape winding speed sensor, and the tape winding speed sensor detects the side retaining ring of the driving synchronous pulley;

[0046] A side retaining ring of the driving synchronous belt wheel is provided with a protrusion, and the winding speed sensor is a proximity switch for detecting the protrusion.

[0047] In this embodiment, the rotation speed of the tape winding frame can be obtained through the tape winding speed sensor, and the winding condition of the copper tape can be monitored in real time.

[0048] In a specific implementation, side retaining rings are provided on both sides of the driving synchronous pulley, one of which is provided with one or more protrusions, and a proximity switch is used as a winding speed sensor to detect these protrusions, and the rotation speed of the winding frame is calculated by the obtained pulse signal.

[0049] See also Figure 2 As a specific embodiment of the cable copper tape wrapping machine provided in the present application, the magnetic powder brake is provided with a first resistance synchronous pulley, and a second resistance synchronous pulley is provided at the rear end of the core tube, and the first resistance synchronous pulley and the second resistance synchronous pulley are connected through a resistance synchronous belt.

[0050] In this embodiment, the magnetic powder brake provides resistance to the core tube through the resistance synchronous belt, which can prevent the belt from slipping and enable the resistance of the magnetic powder brake to be fully transmitted to the core tube.

[0051] See also Figure 1 As a specific embodiment of the cable copper tape wrapping machine provided by the present application, the cable copper tape wrapping machine also includes a copper tape speed sensor, which detects the side retaining ring of the second resistance synchronous pulley;

[0052] A side retaining ring of the second resistance synchronous pulley is provided with a protrusion, and the copper belt speed sensor is a proximity switch for detecting the protrusion.

[0053] In this embodiment, the rotation speed of the copper tape roll on the copper tape fixing seat can be obtained by the copper tape rotation speed sensor, and the wrapping condition of the copper tape can be monitored in real time.

[0054] In the specific implementation, side retaining rings are provided on both sides of the second resistance synchronous pulley. The two side retaining rings limit the resistance synchronous belt to prevent the resistance synchronous belt from falling off. One of the side retaining rings is provided with one or more protrusions. A proximity switch is used as a copper belt speed sensor to detect these protrusions, and the rotation speed of the copper belt roll on the copper belt fixing seat is calculated through the obtained pulse signal.

[0055] See also Figure 1 As a specific embodiment of the cable copper tape wrapping machine provided in the present application, the bottom end of each elastic pressure plate is fixed to the front end side wall of the core tube, and the top end is inclined toward the central axis of the core tube.

[0056] In this embodiment, the wire core is gathered toward the center of the core tube through the bending elasticity of the elastic pressure plate, which can not only ensure the low-resistance passage of the wire core, but also ensure that when the wire core is too close to the side wall of the core tube, there is sufficient thrust to push the wire core back to the center of the core tube.

[0057] In a specific implementation, the bottom end of each elastic pressure plate can be fixed on the end surface of the front side wall of the core tube by bolts, and the top end of each elastic pressure plate is retracted toward the central axis of the core tube to form a hole slightly smaller than the diameter of the wire core. The wire core passes through the hole formed at the top end of each elastic pressure plate, so that each elastic pressure plate is slightly bent outward and deformed, so that each elastic pressure plate forms a small thrust toward the center; when the wire core deviates to one side, the wire core squeezes the elastic pressure plate in the corresponding direction, so that the elastic pressure plate forms a large deformation, pushing the wire core back to the center of the core tube.

[0058] See also Figure 1 As a specific implementation of the cable copper tape wrapping machine provided in the present application, the thickness of the elastic pressing plate gradually decreases from the bottom to the top.

[0059] In this example, when the wire core is located at the center of the core tube, the elastic pressure plate only produces a small deformation at the top, and the resistance to the passage of the wire core is small; when the wire core deviates to one side of the core tube, the part of the elastic pressure plate close to the bottom end is deformed, forming a large elastic force to push the wire core back to the center of the core tube.

[0060] See also Figures 1 to 3 As a specific implementation of the cable copper tape wrapping machine provided in the present application, the elastic pressure plate is a rubber material component.

[0061] In this embodiment, the elastic pressure plate can be made of wear-resistant hard rubber material, and the elastic force generated during bending deformation can be controlled by thickness.

[0062] See also Figure 1 As a specific embodiment of the cable copper tape wrapping machine provided in the present application, a horizontal mounting hole is arranged on the top of the base, and the outer sleeve is rotatably mounted in the mounting hole through at least two bearings;

[0063] The core tube is rotatably mounted in the outer sleeve via at least two bearings.

[0064] In this embodiment, the outer sleeve and the core tube are respectively installed through two bearings, thereby ensuring the stability of their respective rotations.

[0065] The above description is only a preferred embodiment of the present application and is not intended to limit the present application.
