[0028] 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.

[0029] Example 1

[0030] refer to Figures 1-3 An emergency stop device for unwinding copper wire includes a trolley 1, a base frame 2, a necking mold 3, and a take-up mechanism 4 arranged in sequence. The trolley 1 is equipped with a rotatable rotating frame 12, on which copper wire is wound. One end of the copper wire passes through the necking mold 3 and is wound onto the take-up mechanism 4, and is then wound up by the take-up mechanism 4.

[0031] A connecting rod 6 is movably threaded through the base frame 2. A contact plate 61 is provided at one end of the connecting rod 6 facing the trolley 1. A first spring 62 is sleeved between the contact plate 61 and the base frame 2.

[0032] The base frame 2 is provided with a limit switch 5 on the side facing away from the contact plate 61, and the connecting rod 6 is provided with a stop block 63 at the end away from the trolley 1;

[0033] When the copper wire wound on the rotating frame 12 gets knotted, the take-up mechanism 4 pulls the trolley 1 and pushes the contact plate 61 so that the contact block 63 contacts the limit switch 5, thereby stopping the take-up mechanism 4 from winding.

[0034] The necking mold 3 has been disclosed in Chinese patent CN 115889482A, so the structure of the necking mold 3 will not be described in detail in this embodiment.

[0035] In this design, the worker first pulls out one end of the copper wire wound on the rotatable rotating frame 12, passes it through the necking mold 3, and then winds it onto the take-up mechanism 4. The take-up mechanism 4 winds the wire, continuously pulling it out and thinning it after passing through the necking mold 3. When the copper wire on the rotatable rotating frame 12 gets knotted, the take-up mechanism 4 pulls the trolley 1, causing it to move. The trolley 1 then hits and pushes the contact plate 61. Since the connecting rod 6 is movable, this compresses the first spring 62 and causes the contact block 63 to touch the limit switch 5, thereby stopping the take-up mechanism 4 from winding. Afterward, the worker unties the knot, resets the trolley 1, and restarts the take-up mechanism 4. In this way, damage to the copper wire and the equipment can be avoided.

[0036] In this embodiment, there are two connecting rods 6, which are arranged side by side along the length of the base frame 2. The ends of the two connecting rods 6 are connected by the contact plate 61, and the contact block 63 is disposed on one of the connecting rods 6. The two connecting rods 6 can improve the stability of the contact plate 61 during movement.

[0037] Preferably, the base frame 2 is further provided with two U-shaped guide plates 21 and 22 on the side facing the trolley 1;

[0038] The openings of the first guide plate 21 and the second guide plate 22 are arranged opposite to each other. One end of the contact plate 61 is slidably connected in the opening of the first guide plate 21, and the other end is slidably connected in the opening of the second guide plate 22.

[0039] The first guide plate 21 has a first limiting bolt 211 threadedly connected to one end near the trolley 1, and the second guide plate 22 has a second limiting bolt 221 threadedly connected to one end near the trolley 1.

[0040] Specifically, a first guide plate 21 and a second guide plate 22 are provided on the side of the base frame 2 facing the trolley 1, and the two ends of the touch plate 61 are respectively movably connected to the openings of the first guide plate 21 and the second guide plate 22, which can move and guide, and improve the stability of the touch plate 61 during movement.

[0041] Furthermore, to prevent the contact plate 61 from detaching from the first guide plate 21 and the second guide plate 22 when the first spring 62 is reset, the first limiting bolt 211 and the second limiting bolt 221 are respectively vertically set on the end of the first guide plate 21 and the second guide plate 22 near the trolley 1. In this way, the first limiting bolt 211 and the second limiting bolt 221 can limit the contact plate 61 and facilitate the replacement of the first spring 62.

[0042] In this embodiment, the thinning device further includes a base 7, and the base frame 2 and the necking mold 3 are sequentially arranged on the base 7;

[0043] The base frame 2 is provided with a fixing plate 23 on the side opposite to the contact plate 61, and the limit switch 5 is provided on the side of the fixing plate 23 near the connecting rod 6.

[0044] It also includes a fixed rod 8 and a sliding seat 9. The fixed plate 23 is provided with a sliding groove 231 on the side near the connecting rod 6. The fixed rod 8 is vertically arranged in the sliding groove 231, and one end of the fixed rod 8 is connected to the top wall of the sliding groove 231, and the other end is connected to the base 7.

[0045] One end of the sliding seat 9 is movably connected to the slide groove 231. A second spring 81 is sleeved on the fixed rod 8. The second spring 81 is located between the bottom of the sliding seat 9 and the base 7. The limit switch 5 is disposed on the sliding seat 9.

[0046] Specifically, the limit switch 5 is electrically connected to the motor. After the contact block 63 touches the limit switch 5, the winding mechanism 4 stops. However, in order to prevent the contact block from continuing to move and passing the limit switch 5, and being blocked by the limit switch 5 when the first spring 62 drives the contact plate 61 to reset, the worker can press down the sliding seat 9 and position the limit switch 5 below the contact block 63. In this way, when the first spring 62 resets, it will not be blocked by the limit switch 5 and the contact block 63 will return to its original position.

[0047] Preferably, the trolley 1 includes a base plate 11, a turntable 121 disposed on the base plate 11, and a connecting frame 122 disposed on the turntable 121. The bottom of the base plate 11 is provided with a plurality of universal wheels 13, and the end of the base plate 11 near the touch plate 61 is provided with a mounting plate 45 for contacting the touch plate 61; copper wire is wound on the connecting frame 122.

[0048] Furthermore, the connecting frame 122 is set on the turntable 121, which is higher than the mounting plate 14. When the winding mechanism 4 winds up the wire, it drives the turntable 121 to rotate so that the copper wire is released. When the copper wire is knotted, the winding mechanism 4 will pull the base plate 11 towards the contact plate 61. Under the continuous pulling of the winding mechanism 4, the mounting plate 45 will touch the contact plate 61, thereby pushing the contact plate 61 and causing the contact block 63 to touch the limit switch 5.

[0049] Preferably, the take-up mechanism 4 includes a fixed frame 41 and a take-up roller 42 rotatably connected to the fixed frame 41. The fixed frame 41 is provided with a motor (not shown in the figure) for driving the take-up roller 42 to rotate. The motor is connected to one end of the take-up roller 42. The copper wire wound on the rotating frame 12 is wound onto the take-up roller 42 after passing through the necking mold 3.

[0050] Furthermore, one end of the copper wire is wound around the take-up roller 42. The rotation of the take-up roller 42 is driven by a motor, which in turn pulls out the copper wire from the rotating frame 12 and makes it thinner after passing through the necking mold 3.

[0051] 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.
