Description

Technical Field

[0001] This utility model relates to the protection against breakage and exhaustion of wires, and more particularly to a device for fixed-point power-off shutdown at the end of a cored wire sheath. Background Technology

[0002] Normally, automatic unwinding equipment used for cored wire, tubing, and winding should be stopped promptly after all material has been released to avoid two situations: 1. Failure to stop in time results in no cored wire remaining in the forming machine, requiring manual feeding of cored wire and re-adjustment of the equipment. This increases labor intensity, wastes raw materials during the adjustment process, and affects production quantity and quality. 2. Relying on operators to visually inspect for used cored wire during production to prevent excessive waste results in the machine being stopped and discarded when only about 10 rolls (approximately 10 meters) of cored wire remain on each roll, leading to significant waste.

[0003] Based on the above reasons, and with the aim of saving raw materials, avoiding equipment damage, and reducing the labor intensity of operators, a fixed-point power-off shutdown device for the end of the cored wire sheath was developed.

[0004] The purpose of this invention is to completely solve the problem of equipment idling and requiring manual adjustment during the production of cored wire, thereby reducing the labor intensity of operators and equipment damage, and minimizing the waste of raw materials caused by repeated adjustments.

[0005] This invention can automatically stop the machine at designated points according to the requirements, reducing the waste of core-coated wire from about 10 meters per reel to 0.1 meters. Based on the current daily use of 25 reels of core-coated wire, the savings are considerable. Utility Model Content

[0006] The purpose of this invention is to address the above-mentioned problems by providing a device for fixed-point power-off shutdown at the end of the cored wire sheath.

[0007] The purpose of this utility model is achieved as follows: a fixed-point power-off device at the end of a core-insulated wire includes a swing-arm self-spring switch, a vertical support, and a leakage current protection device; the swing-arm self-spring switch is installed on the inner side of the vertical support at a distance of 40-50mm from the top, the swing-arm self-spring switch is fixed by bolts, the swing-arm roller of the swing-arm self-spring switch is close to the middle of the core-insulated wire and presses on the running core-insulated wire, and the swing-arm self-spring switch is electrically connected to the leakage current protection device.

[0008] The vertical support is made of angle steel.

[0009] The beneficial effects of this utility model are: 1. It has a simple structure, is easy to install, requires little investment, but saves on raw material costs and has obvious effects.

[0010] 2. It can cut off power and stop the machine at a fixed point in time, avoiding equipment failure and waste of raw materials caused by repeated debugging.

[0011] 3. Each roll of cored wire sheath can be fully utilized, eliminating unnecessary increases in labor intensity caused by idle equipment and repeated adjustments, thus ensuring stable production operation. Attached Figure Description

[0012] The present invention will now be further described with reference to the accompanying drawings.

[0013] Figure 1 This is a schematic diagram of the structure of this utility model in normal operation.

[0014] Figure 2 This is a schematic diagram of the structure of this utility model where power is cut off when the material is exhausted.

[0015] The components include: 1. Vertical support, 2. Bolts and self-locking nuts, 3. Swing arm type self-springing switch, 4. Wire, 5. Guide wheel, and 6. Core-insulated wire. Detailed Implementation

[0016] This utility model comprises five parts: a swing-arm self-springing switch 1, a straight vertical support 2, a fixing bolt 3, a wire 4, and a self-locking nut 5. This utility model utilizes a combination of a swing-arm self-springing switch and a straight vertical support. Four φ5mm holes are drilled in the limit switch base 50mm from the top of the vertical support. The roller at the top of the limit switch's rocker arm is in close contact with the middle of the cored wire sheath, and the roller of the swing arm presses against the running cored wire sheath. When the cored wire sheath is not completely used, the power-off switch will continue to supply power, ensuring normal cored wire production. Whenever the cored wire sheath is used up, the roller of the metal swing arm of the power-off limit switch disengages from the cored wire sheath, realizing a power-off shutdown of the cored wire forming machine and protecting the equipment from damage caused by material shortage.

[0017] With a simple structure and convenient installation, the power should be disconnected before installation. The swing-arm self-release switch is fixed to the vertical support with bolts. Next to the cored wire feeding frame, select a point on the vertical support that is the length of the swing-arm self-release switch from the transverse center line of the cored wire sheath. This can be fixed by welding (or bolting). Connect the power cord to the residual current device (RCD) in the distribution cabinet to achieve power outage, tripping, and shutdown protection. This eliminates material waste at the end of the cored wire sheath and reduces equipment failures. It saves costs, reduces operator workload, and ensures stable and reliable operation.

[0018] The model of the swing-arm self-opening switch is ME-8108. The swing-arm self-opening switch is electrically connected to the residual current device (RCD). The swing-arm self-opening switch and the RCD share the same power supply. The power supply is connected in parallel with the swing-arm self-opening switch and the RCD. The swing-arm self-opening switch and the RCD are connected in series. When the core insulation of the wire is completely released (or breaks), the swing-arm self-opening switch disconnects the circuit, thereby causing the contactor to return to its original position, the motor to stop running, and the equipment to stop.

[0019] The vertical support is made of 40mm×40mm angle steel.

[0020] 1. During normal operation, the limit switch is in the ON state.

[0021] 2. After the core wire sheath is used up, the limit switch is in the off state.

[0022] After a week of installation and trial use of the No. 1 cored wire machine, the effect was obvious. It reduced equipment damage caused by the breakage of the cored wire sheath during the cored wire forming process, and ensured that the cored wire sheath of each roll was completely used, eliminating raw material waste and saving raw material procurement costs.

[0023] 1. Equipment safety: It can effectively prevent the molding machine from malfunctioning and being damaged due to the failure to detect the use of cored wire in time.

[0024] 2. Cost management: Fixed-point power outage shutdown effectively avoids the waste of cored wire sheath and alloy raw materials caused by manual pre-shutdown and repeated debugging, effectively saving raw material costs.

[0025] 3. Avoid repeated debugging, which increases the labor intensity of operators and is not conducive to safe and stable production.

[0026] 4. This method fundamentally eliminates the problem of undetected use of all cored wire sheaths, which would result in the molding machine being without cored wire sheaths. In such cases, the cored wire sheaths would have to be manually fed back into the molding machine, and the equipment would have to be readjusted. This avoids repetitive work, reduces the labor intensity of operators, and saves on the waste of cored wire sheaths and alloy raw materials during the debugging process.

[0027] The above description is only a specific embodiment of the present utility model, but the structural features protected by the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
