Description

Technical Field

[0001] This utility model belongs to the field of copper wire production technology, specifically a safety device for copper wire conveying. Background Technology

[0002] Copper wire has many advantages: low resistivity, good ductility, high strength, fatigue resistance, good stability, high current carrying capacity, low voltage drop, low heat generation, and low electrical loss, leading to its widespread application. At the same time, copper wire is also an important conductive material. Due to its excellent conductivity, good mechanical properties, and good corrosion resistance, it has been widely used in power transmission, electronic equipment, and various industrial fields since ancient times.

[0003] CN202223357074.X discloses a take-up device for a rolling mill, including a take-up unit and a speed adjustment device. The take-up unit includes a take-up spool and a motor, which controls the rotation of the take-up spool. The speed adjustment device is located between the output end of the external rolling mill and the input end of the take-up unit. The speed adjustment device includes a support frame, a first guide shaft, a first position sensor, a second position sensor, and a take-up wheel assembly. The take-up wheel assembly includes a first roller fixed on the support frame and a second roller sleeved on the first guide shaft via a first connecting member. Both the first roller and the second roller are provided with guide grooves. The first position sensor and the second position sensor are located on both sides of the support frame to detect the position change of the second roller. The first position sensor is electrically connected to the motor and sends a deceleration signal, and the second position sensor is electrically connected to the motor and sends an acceleration signal.

[0004] In the above technical solution, the position of the second roller is detected by the first position sensor and the second position sensor, and a signal is sent to the motor to control the winding speed in order to control the tension. However, when the copper wire gets tangled during the winding process, the motor will keep pulling the second roller up and causing it to collide with the first roller. After the collision, the motor will continue to wind up, which will damage the equipment and the copper wire. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] refer to Figures 1-4 A safety device for copper wire conveying includes a wire feeding mechanism 1 with copper wire wound on it, a base 2, a slider assembly 6, and two guide rods 9 vertically arranged on the base 2. The top ends of the two guide rods 9 are connected by a fixing block 101, and the slider assembly 6 is movably inserted through the two guide rods 9.

[0030] A first roller 3 is provided on one side of the fixed block 101, and a second roller 4 is provided below the first roller 3. The second roller 4 is connected to one side of the slider assembly 6. The first roller 3 is provided with a first winding groove 31 and a second winding groove 32. The copper wire passes through the first winding groove 31, the second roller 4 and the second winding groove 32 in sequence and is wound on the external rolling mechanism, and is wound up by the external rolling mechanism.

[0031] The base 2 is equipped with a limit switch 211 assembly, and the slider assembly 6 is equipped with a contact rod 5. When the copper wire is knotted and the slider assembly 6 is pulled upward by the external rolling mechanism, the contact rod 5 contacts the limit switch 211 assembly, thereby stopping the external rolling mechanism from winding.

[0032] In this design, the worker sequentially winds one end of the copper wire on the unwinding mechanism 1 around the first winding groove 31 of the first roller 3, the second roller 4, and the second winding groove 32 of the first roller 3 before winding it onto the external rolling mechanism. The external rolling mechanism winds the copper wire. When a knot occurs at the unwinding mechanism 1 during the winding process, the external rolling mechanism continuously pulls the slider assembly 6 upward, thereby driving the second roller 4 and the moving contact rod 5 upward. After moving upward a certain distance, the contact rod 5 contacts the limit switch 211 assembly, thereby stopping the external winding mechanism. The worker can then manually untie the knot, or cut off the knot and rewind the wire before restarting the external rolling mechanism. In this way, when the copper wire gets knotted, the external mechanism can be automatically stopped, avoiding damage to the equipment and the copper wire.

[0033] In this embodiment, the slider assembly 6 includes a slider 61 that is movably mounted on two guide rods 9, the second roller 4 is disposed on one side of the slider 61, and the contact rod 5 is disposed at the top of the slider 61.

[0034] It also includes a first spring 7 sleeved on the guide rod 9. The first spring 7 is located between the fixed block 101 and the sliding assembly. The lower end of the first spring 7 is connected to the slider assembly 6. The length of the first spring 7 is 1 / 6 of the length of the guide rod 9.

[0035] Specifically, when a knot occurs at the wire feeding point, the copper wire will bypass the second roller 4. Therefore, the external rolling mechanism will drive the slider 61 to move upward on the guide rod 9, causing the second roller 4 and the first roller 3 to collide. Therefore, by sleeved on the guide rod 9, the upper end of the first spring 7 will contact the fixed block 101 when the external rolling mechanism keeps pulling the second roller 4 upward, thereby avoiding the collision between the first roller 3 and the second roller 4. The length of the first spring 7 is preferably 1 / 6 of the length of the guide rod 9.

[0036] Preferably, the assembly further includes a second spring 8 sleeved on the guide rod 9, the lower end of the second spring 8 being connected to the base 2, and the upper end of the second spring 8 being provided with a buffer member 81. The buffer member 81 is sleeved on the guide rod 9 and is located below the slider assembly 6.

[0037] Generally, workers will use the cutting method to untie the knotted copper wire, which is relatively quick. However, after cutting, the slider assembly 6 slides down under the action of gravity. In order to prevent the slider 61 from sliding down and hitting the base plate, a second spring 8 is set. A buffer 81 is set at the upper end of the second spring 8 so that the buffer 81 contacts the sliding slider assembly 6.

[0038] Furthermore, the limit switch 211 assembly includes a limit switch 211, a first fixing plate 212 and a second fixing plate 213 with a U-shaped structure, the first fixing plate 212 and the second fixing plate 213 are vertically disposed on the base 2, and the first fixing plate 212 and the second fixing plate 213 are arranged at intervals along the horizontal direction.

[0039] The openings of the first fixing plate 212 and the second fixing plate 213 are arranged opposite to each other, and the slider 61 is disposed between the first fixing plate 212 and the second fixing plate 213;

[0040] The first fixing plate 212 is provided with a mounting base 214 on the side away from the second roller 4. The limit switch 211 is provided on the mounting base 214. The limit switch 211 is located between the first roller 3 and the second roller 4. The contact rod 5 is provided on the side of the slider 61 facing away from the second roller 4. One end of the contact rod 5 extends in a direction away from the second roller 4.

[0041] Specifically, the limit switch 211 is electrically connected to the rolling mechanism of the external device. The limit switch 211 is mounted on the mounting base 214 of the first fixed plate 212. When the knot is tied and the slider 61 is driven to move upward through the rolling mechanism of the external device, the contact rod touches the limit switch 211 and sends a signal to the rolling mechanism of the external device, thereby stopping the rolling mechanism of the external device.

[0042] In this embodiment, the buffer 81 is a ring structure, and the buffer 81 is made of rubber. The rubber buffer 81, in conjunction with the second spring 8, buffers the slider 61.

[0043] Preferably, the wire feeding mechanism 1 includes a fixed frame 11, a turntable 12 disposed on one side of the fixed frame 11, and a connecting frame 13 disposed on one side of the turntable 12, with the copper wire wound on the connecting frame 13.

[0044] Furthermore, the copper wire is wound on the connecting frame 13. One end of the copper wire is wound around the first winding groove 31 of the first roller 3, the second roller 4 and the second winding groove 32 of the first roller 3, and then wound onto the external rolling mechanism, and then wound up by the external rolling mechanism.

[0045] Preferably, the second fixing plate 213 is provided with a first position sensor 2131 and a second position sensor 2132. The limit switch 211 is generally located above the first position sensor 2131.

[0046] The functions of the first position sensor 2131 and the second position sensor 2132 have been disclosed in Chinese patent CN218656173U, so they will not be explained in detail in this embodiment.

[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of the present utility model, and these improvements or modifications should also be considered within the protection scope of the present utility model.
