Description

Technical Field

[0001] The utility model belongs to the technical field of disc-shaped welding wire transportation, in particular to a wire feeding device. Background Art

[0002] Currently, coiled welding wire is often transported via conveyors before entering the processing steps. However, when two adjacent coils are placed on the conveyor, the distance between them is small. This can cause the next coil to enter the processing step before the previous coil has completed the processing step, leading to material accumulation within the processing step. Utility Model Content

[0003] In order to overcome the defects of the prior art, the utility model provides a wire feeding device which can feed the disc-shaped welding wire in an orderly manner.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] A wire feeding device includes a roller conveyor for conveying a coiled welding wire, the roller conveyor including a plurality of rollers arranged longitudinally, a first guardrail provided on both sides of the roller conveyor, and two limit rods that move vertically under the action of a linear drive mechanism, the two limit rods being arranged transversely between two adjacent rollers, the spacing between the two limit rods and the spacing between any limit rod and its adjacent first guardrail being less than the diameter of the coiled welding wire;

[0006] A photoelectric switch is provided at the front end of the limit rod on the outside of the roller conveyor. The longitudinal distance between the photoelectric switch and the limit rod matches the diameter of the disc welding wire. The photoelectric switch and the linear drive mechanism are both electrically connected to a controller.

[0007] The beneficial effects of adopting the above technical solution are as follows: the roller conveyor can rely on several rollers thereon to convey the disc-shaped welding wire. When the front end of the disc-shaped welding wire reaches the irradiation path of the photoelectric switch, the linear drive mechanism can drive the limit rod to move vertically upward to temporarily block the next disc-shaped welding wire from being conveyed forward. When the rear end of the disc-shaped welding wire passes through the irradiation path of the photoelectric switch, the linear drive mechanism can drive the limit rod to move vertically downward to enable the next disc-shaped welding wire to continue to be conveyed, thereby adjusting the spacing between adjacent disc-shaped welding wires, which is conducive to the orderly conveyance of the disc-shaped welding wire.

[0008] In one embodiment, when the output end of the linear drive mechanism is not extended, the upper end of the limit rod is lower than the upper end of the roller; when the output end of the linear drive mechanism is extended, the upper end of the limit rod is higher than the upper end of the roller.

[0009] The beneficial effects of adopting the above technical solution are: when the output end of the linear drive mechanism is not extended, the upper end of the limit rod is lower than the upper end of the roller, that is, at this time the limit rod cannot prevent the disc-shaped welding wire from being conveyed forward; when the output end of the linear drive mechanism is extended, the upper end of the limit rod is higher than the upper end of the roller, that is, at this time the limit rod can prevent the disc-shaped welding wire from being conveyed forward.

[0010] In one embodiment, the roller conveyor includes a support frame, and the linear drive mechanism is fixedly connected to the support frame.

[0011] In one embodiment, the output end of the linear drive mechanism is fixedly connected to two limiting rods.

[0012] The beneficial effect of adopting the above technical solution is: a linear drive mechanism drives two limit rods to make the two limit rods move vertically synchronously, thereby ensuring that the two limit rods can synchronously limit the forward feeding of the disc-shaped welding wire.

[0013] In one embodiment, the output end of the linear drive mechanism is arranged vertically upward.

[0014] In one embodiment, a horizontal second guardrail is fixedly connected to the roller conveyor, and the limiting rod is located directly below the second guardrail.

[0015] The beneficial effect of adopting the above technical solution is that the second guardrail can limit the coiled welding wire above the roller to prevent the coiled welding wire from turning over the limit rod in a flipping form.

[0016] In one embodiment, the distance between the second guardrail and the roller is greater than the height of the coiled welding wire.

[0017] The beneficial effect of adopting the above technical solution is: such arrangement can prevent the second guardrail from interfering with the conveyance of the coiled welding wire on the roller conveyor.

[0018] In one embodiment, the outer side of the roller conveyor is fixedly connected to the outer side of the second guardrail.

[0019] The beneficial effect of adopting the above technical solution is: it is arranged so that the connection structure between the second guardrail and the roller conveyor is located outside the roller, thereby preventing the connection structure between the second guardrail and the roller conveyor from affecting the conveyance of the disc-shaped welding wire.

[0020] In one embodiment, a switch electrically connected to the controller is fixedly connected to the roller conveyor.

[0021] The beneficial effects of adopting the above technical solution are: a switch is fixed on the roller conveyor to facilitate starting devices such as the photoelectric switch and the linear drive mechanism through the switch.

[0022] In one embodiment, a control box for housing a controller is fixedly connected to the roller conveyor.

[0023] The beneficial effect of adopting the above technical solution is: such an arrangement allows the controller to be protected by the control box.

[0024] The beneficial effects of the present invention are:

[0025] The roller conveyor can rely on several rollers on it to convey the disc-shaped welding wire. When the front end of the disc-shaped welding wire reaches the irradiation path of the photoelectric switch, the linear drive mechanism can drive the limit rod to move vertically upward to temporarily block the next disc-shaped welding wire from being conveyed forward. When the rear end of the disc-shaped welding wire passes through the irradiation path of the photoelectric switch, the linear drive mechanism can drive the limit rod to move vertically downward to enable the next disc-shaped welding wire to continue to be conveyed, thereby adjusting the spacing between adjacent disc-shaped welding wires, which is conducive to the orderly conveyance of the disc-shaped welding wire.

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] The utility model provides a wire feeding device, such as Figure 1 and Figure 2 As shown, it includes a roller conveyor 1 for conveying a coiled welding wire 3. The roller conveyor 1 includes a plurality of rollers 101 arranged in the longitudinal direction. A first guardrail 102 is provided on both sides of the roller conveyor 1. The roller conveyor 1 also includes two limit rods 4 that move vertically under the action of a linear drive mechanism 7. The two limit rods 4 are arranged in the transverse direction between two adjacent rollers 101. The spacing between the two limit rods 4 and the spacing between any limit rod 4 and its adjacent first guardrail 102 are both smaller than the diameter of the coiled welding wire 3.

[0035] A photoelectric switch 2 is provided on the outside of the roller conveyor 1 and is located at the front end of the limit rod 4. The longitudinal distance between the photoelectric switch 2 and the limit rod 4 matches the diameter of the disc welding wire 3. The photoelectric switch 2 and the linear drive mechanism 7 are both electrically connected to a controller.

[0036] It can be understood that the roller conveyor 1 can rely on the several rollers 101 thereon to convey the disc-shaped welding wire 3. When the front end of the disc-shaped welding wire 3 reaches the irradiation path of the photoelectric switch 2, the linear drive mechanism 7 can drive the limit rod 4 to move vertically upward to temporarily block the next disc-shaped welding wire 3 from being conveyed forward. When the rear end of the disc-shaped welding wire 3 passes through the irradiation path of the photoelectric switch 2, the linear drive mechanism 7 can drive the limit rod 4 to move vertically downward to enable the next disc-shaped welding wire 3 to continue to be conveyed, thereby adjusting the spacing between adjacent disc-shaped welding wires 3, which is conducive to the orderly conveyance of the disc-shaped welding wire 3.

[0037] It should be noted that the remaining structures of the roller conveyor 1 are conventional technologies and will not be described in detail here; in addition, the linear drive mechanism 7 can be an electric push rod, and the controller can be a PCB board equipped with a C51 single-chip microcomputer; the outer side of the roller conveyor 1 can also be provided with a photoelectric sensor located at the rear end of the limit rod 4 facing inward, and the photoelectric sensor is electrically connected to the controller.

[0038] In one embodiment, when the output end of the linear drive mechanism 7 is not extended, the upper end of the limit rod 4 is lower than the upper end of the roller 101; when the output end of the linear drive mechanism 7 is extended, the upper end of the limit rod 4 is higher than the upper end of the roller 101.

[0039] It can be understood that when the output end of the linear drive mechanism 7 is not extended, the upper end of the limit rod 4 is lower than the upper end of the roller 101, that is, at this time the limit rod 4 cannot prevent the disc-shaped welding wire 3 from being conveyed forward; when the output end of the linear drive mechanism 7 is extended, the upper end of the limit rod 4 is higher than the upper end of the roller 101, that is, at this time the limit rod 4 can prevent the disc-shaped welding wire 3 from being conveyed forward.

[0040] In one embodiment, the roller conveyor 1 includes a support frame 103 , and the linear drive mechanism 7 is fixedly connected to the support frame 103 .

[0041] In one embodiment, the output end of the linear drive mechanism 7 is fixedly connected to two limiting rods 4 .

[0042] It can be understood that one linear drive mechanism 7 drives two limit rods 4 so that the two limit rods 4 move vertically synchronously, thereby ensuring that the two limit rods 4 can synchronously limit the forward feeding of the coiled welding wire 3.

[0043] In one embodiment, the output end of the linear drive mechanism 7 is arranged vertically upward, and the limiting rod 4 is also arranged vertically.

[0044] In one embodiment, a horizontal second guardrail 5 is fixedly connected to the roller conveyor 1 , and the limiting rod 4 is located directly below the second guardrail 5 .

[0045] It can be understood that the second guardrail 5 can restrict the coiled welding wire 3 above the roller 101 to prevent the coiled welding wire 3 from turning over the limiting rod 4 in a flipping manner.

[0046] In one embodiment, the distance between the second guardrail 5 and the roller 101 is greater than the height of the coiled welding wire 3 to prevent the second guardrail 5 from interfering with the conveyance of the coiled welding wire 3 on the roller conveyor 1 .

[0047] It should be noted that when the linear drive mechanism 7 is fully extended, the upper end of the limiting rod 4 needs to reach the lower end of the second guardrail 5 .

[0048] In one embodiment, the outer side of the roller conveyor 1 is fixedly connected to the outer side of the second guardrail 5 so that the connection structure between the second guardrail 5 and the roller conveyor 1 is located on the outer side of the roller 101, thereby avoiding the connection structure between the second guardrail 5 and the roller conveyor 1 affecting the transportation of the disc welding wire 3.

[0049] In one embodiment, a switch 8 electrically connected to the controller is fixedly connected to the roller conveyor 1 .

[0050] It is understandable that a switch 8 is fixed on the roller conveyor 1 to facilitate starting devices such as the photoelectric switch 2 and the linear drive mechanism 7 through the switch 8 .

[0051] It should be noted that the roller conveyor 1 can also be electrically connected to the controller so as to be uniformly controlled by the switch 8 .

[0052] In one embodiment, a control box 6 for housing a controller is fixedly connected to the roller conveyor 1 , so that the controller is protected by the control box 6 .
