Description

Technical Field

[0001] This application relates to the field of wire feeder equipment technology, and in particular to a spring-loaded wire feeder without inductive current. Background Technology

[0002] The wire feeder of the spring machine is a key auxiliary device in spring manufacturing equipment. It is mainly used for stable wire feeding and synchronous control to ensure the efficient operation of the spring machine.

[0003] After the wire feeder delivers all the spring raw material wire wound on the spool to the spring machine, it will idle. This idle state wastes power. The machine is equipped with an alarm device that stops operation and alerts the worker when the wire feeder runs out of spring raw material wire (i.e., the wire breaks). The worker will then place the spring raw material wire on the spool to continue feeding it to the spring machine. However, placing the spring raw material wire on the spool can cause electric shock due to induced current. This electric shock can be small or large, causing physical or stress-related injuries to the worker. Over time, this can severely damage health and hinder work performance. Summary of the Invention

[0004] This application aims to solve the technical problem that when workers place spring raw material wire on the wire reel of the wire feeder, electric shock may occur due to induced electricity. This electric shock can be large or small, causing physical or stress-related injuries to workers. Over time, it can seriously damage human health and hinder workers' work. The application provides a wire feeder for spring machines that is free from induced electricity.

[0005] This application employs the following technical means to solve the technical problem:

[0011] An alarm sensing electrical guiding structure, comprising a frequency converter, a relay, a busbar, and an alarm grounding wire;

[0012] The frequency converter and relay are located inside the wire feeding frame, and the wire bar is located on the outer wall of the wire feeding frame. The frequency converter, relay, wire bar and alarm grounding wire are electrically connected to each other, and the other end of the alarm grounding wire is connected to the spring mechanism.

[0013] Furthermore, the spring-driven linear transmission structure includes an output motor, a first transmission wheel, a second transmission wheel, a transmission belt, an inner shaft, and a connecting rod;

[0014] The first transmission wheel is mounted on the first support plate, the second transmission wheel is mounted on the second support plate, the transmission belt is mounted on the first transmission wheel and the second transmission wheel, the output end of the output motor is connected to the first transmission wheel, and the output motor drives the first transmission wheel to rotate through the transmission belt;

[0025] Reference Appendix Figure 1 This is a schematic diagram of the overall structure of the non-inductive spring machine wire feeder in one embodiment of this application;

[0026] Example 1

[0027] A wire feeder for a spring machine 7 without inductive current, the wire feeder conveying spring wire to the spring machine 7, comprising:

[0028] The housing includes a wire feed frame 1, a first support plate 2, a second support plate, and a top connecting rod 11;

[0029] The first support plate 2 and the second support plate are disposed inside the wire feeding frame 1, and the top connecting rod 11 is disposed on the outer surface of the wire feeding frame 1;

[0030] A spring wire drive mechanism is provided inside the wire feeding frame 1, and the spring wire drive mechanism is used to convey the spring wire from the wire feeding frame 1 to the spring machine 7.

[0031] A spring wire limiting structure is provided outside the wire feeding frame 1, and the spring wire limiting structure is used to restrict the spring wire from disengaging from the spring wire transmission mechanism.

[0032] An alarm sensing electrical guiding structure, comprising a frequency converter 15, a relay 4, a busbar 5, and an alarm grounding wire 6;

[0033] The frequency converter 15 and the relay 4 are located inside the wire feeding frame 1, and the wire bar 5 is located on the outer wall of the wire feeding frame 1. The frequency converter 15, the relay 4, the wire bar 5 and the alarm grounding wire 6 are electrically connected to each other, and the other end of the alarm grounding wire 6 is connected to the spring mechanism 7.

[0034] In this embodiment, the spring-wire transmission structure includes an output motor, a first transmission wheel 3, a second transmission wheel 9, a transmission belt 8, an inner shaft 10, and a connecting rod 13;

[0035] The first transmission wheel 3 is disposed on the first bearing plate 2, the second transmission wheel 9 is disposed on the second bearing plate, the transmission belt 8 is disposed on the first transmission wheel 3 and the second transmission wheel 9, the output end of the output motor is connected to the first transmission wheel 3, and the output motor drives the first transmission wheel 3 to drive the second transmission wheel 9 to rotate through the transmission belt 8;

[0036] The second transmission wheel 9 is connected to the inner shaft 10, and the inner shaft 10 is connected to the connecting rod 13. The inner shaft 10 extends from the second bearing plate to the outside of the wire feeding frame 1.

[0037] The spring wire limiting structure includes a cover plate 14, which is disposed between the connecting rod 13 and the inner shaft 10. The side of the cover plate 14 facing the inner shaft 10 has a groove.

[0038] Specifically,

[0039] The operator first turns on the spring machine 7, then places a coil 12 on the inner shaft 10. The coil 12 winds the spring wire into a disc, and one end of the coil 12 is connected to the spring machine 7. Next, the output motor outputs power to the first transmission wheel 3. The rotation of the first transmission wheel 3 drives the second transmission wheel 9 to rotate through the transmission belt 8. When the second transmission wheel 9 rotates, it drives the inner shaft 10 to rotate. During the rotation of the inner shaft 10, the coil 12 is conveyed in accordance with the winding rhythm of the spring machine 7, so as to achieve the purpose of the wire feeding frame cooperating with the spring machine 7 to feed the wire into springs.

[0040] In this embodiment, the spring wire is wound into a coil 12 and placed on the inner shaft 10, and one end of the spring wire is connected to the spring machine 7. The alarm grounding wire 6 is connected from the wire row 5 and connected to the spring machine 7.

[0041] Specifically,

[0042] When the wire reel 12 on the wire feeder has finished feeding the wire to the spring machine 7, the worker may be electrocuted by the induced current when placing a new wire reel 12 on the wire feeder. Under such circumstances, it is difficult to provide safety protection for the workers.

[0043] However, existing wire feeders are usually equipped with a wire breakage alarm device, namely the alarm grounding wire 6 in this application. But existing wire feeders cannot perform grounding and current dissipation functions at the same time as the wire breakage alarm. When the wire reel 12 finishes feeding the spring wire, or when any one of the alarm grounding wires 6 breaks, the wire feeder will stop and alarm to remind the staff that the wire reel 12 on the wire feeder has finished feeding. At the same time, the frequency converter 15 will output a set of power to the relay 4, and then to the grounding connector. The grounding wire is connected to the wire breakage alarm line to cancel the induced electricity. Therefore, people will not be harmed by induced electricity when they touch the housing of the wire feeder.
