Description

Technical Field

[0001] The utility model belongs to the technical field of cable cutting, and particularly relates to a cable reel. Background Art

[0002] Cable reels are used to wind wires and cables. During use, they can be paid out and cut to the required length. Existing technologies often rely on manual payout and cutting. However, this method is time-consuming and labor-intensive, inconvenient, and prone to hand injuries. Operators need to measure the payout length themselves, resulting in low cutting accuracy and production efficiency, making it difficult to meet the needs of large-scale cable processing.

[0003] For example, there is a Chinese patent with publication number CN219966295U, which relates to a cable pay-off and cutting device for a cable reel, including an adjustment device, the adjustment device including a motor, a bidirectional threaded rod fixedly mounted on the output end of the motor, a first threaded member and a second threaded member threadedly sleeved on the surface of the bidirectional threaded rod, a cutting device body fixedly mounted on the top surface of the first threaded member, a positioning platform fixedly mounted on the top surface of the second threaded member, the cutting device body including a cutting table, a fixing member fixedly mounted on one side of the top surface of the cutting table, the bidirectional threaded rod is driven by the motor to rotate, and while the bidirectional threaded rod rotates, the first threaded member and the second threaded member mounted on the surface of the bidirectional threaded rod are driven to slide relative to each other, and the cutting device body is driven to move by the first threaded member, when the cutting table of the cutting device body moves to the middle of the bottom of the cable body, the cutting blade is driven by the cylinder to cut the cable body, thereby avoiding the problem of the cable instantly rebounding when manually cutting the cable with a cutting tool, which can easily cause injury to the operator. However, this patent still requires the operator to control the cable length himself, making cutting accuracy difficult to ensure and reducing production efficiency. Utility Model Content

[0081] The following describes in detail a method for using a cable reel according to the present invention.

[0082] First, install the cables.

[0083] Place the designated cable on the pay-off drum as required. Pass the cable through the guide rod in a counterclockwise direction along the pay-off drum and then install it on the wire-passing device.

[0084] Specifically, the following steps are taken to install the cable on the wire-passing device.

[0085] Pass the cable from under the crimping wheel, then wrap it around the encoder synchronization wheel, and then pass the cable through the wire passing hole of the wire passing device and the limit piece of the front seat of the wire rack in turn, and lead it out to the wire cutter jaws on the front side of the wire rack front seat.

[0086] Finally, lead the cable out of the wire cutters, cover it with the shielding cover, and the cable installation is complete.

[0087] During operation, the upper computer sends the cable length requirement, and the operator pulls the cable according to the corresponding number of meters. As the cable is pulled, the number of meters pulled is displayed in real time on the display screen. When the operator pulls to the corresponding number of meters, the brake device is activated to stop the rotation of the cable drum. At this time, pulling the cable will become very difficult. The operator completes the pulling operation by default and manually presses down the wire cutters to cut the cable. After the operation is completed.

[0088] The working principle of the wire passing device is described in detail below.

[0089] First, the cable is passed through from under the crimping wheel, then wrapped around the encoder synchronization wheel, and then the cable is led out through the wire through hole and the limiter to the front of the wire rack front seat.

[0090] When the cable is pulled, the cable drives the encoder synchronous wheel to rotate together with it through friction with the encoder synchronous wheel, and then drives the encoder output shaft to rotate together, thereby achieving the counting requirements.

[0091] The working principle of the brake device is described in detail below.

[0092] When the cable is pulled to meet the task requirements, the electromagnet will retract and extend, driving the brake seat to move forward and backward.

[0093] Because the fixing member is fixed on the brake base plate and the slide rod of the lifting member is connected to the second sliding groove of the fixing member, the lifting member can only move up and down in the second sliding groove.

[0094] When the brake device is not working, the slide rod of the lifting member corresponds to the lowest point of the first sliding groove, and the slide rod of the lifting member is located at the bottom of the second sliding groove.

[0095] When the brake seat moves forward, the first slide groove on the brake seat and the slide rod of the lifting member produce relative displacement, the slide rod slides in the inclined first slide groove, and the higher part of the first slide groove gradually moves to the position corresponding to the slide rod, and the slide rod moves upward, thereby driving the lifting member to move upward, and the second friction member is driven to move upward, and then contacts the bottom surface of the pay-off drum.

[0096] At the same time, as the brake seat moves forward, the first friction member on the brake seat gradually contacts the edge of the pay-off drum, generating friction with the edge of the pay-off drum.

[0097] The two friction members respectively contact the pay-off drum, generate friction with the pay-off drum, and thus limit the rotation of the pay-off drum.

[0098] When the movement reaches a certain extent, the supporting part of the connecting part on the electromagnet will approach the lifting part, the friction part will contact the edge of the pay-off disk, the forward movement will stop, the electromagnet will start to move backward and drive the brake seat to move backward.

[0099] Similarly, when the brake seat moves backward, the first slide groove on the brake seat and the slide rod of the lifting member produce relative displacement, the slide rod slides in the inclined first slide groove, and the lower part of the first slide groove gradually moves to the position corresponding to the slide rod, and the slide rod moves downward, thereby driving the lifting member to move downward, and the second friction member moves downward and separates from the bottom surface of the pay-off disk.

[0100] When the cable pulling reaches the task requirements, the brake device works and the electromagnet begins to extend and retract, driving the brake seat to move back and forth, so that the two friction parts continuously contact the pay-off drum to limit the rotation of the pay-off drum.
