[0024] Secondly, the "one embodiment" or "embodiment" referred to here means that the specific features, structures or characteristics can be included in at least one implementation of the utility model. In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.
[0025] Embodiment
[0026] Reference Figures 1-4 For the embodiment of the utility model, the embodiment provides a wire feeder capable of automatically changing wire, which can realize the effect of automatically loading new welding wire into the positioning frame 105 through a single driving source when the welding wire is exhausted, and clamping and conveying the welding wire to the welding area.
[0027] The wire feeding mechanism 100 comprises a support table 101, a first motor 102 fixedly installed on the top of the support table 101, a driving roller 103 fixedly sleeved on the output end of the first motor 102, a driven roller 104 arranged outside the driving roller 103, and a positioning frame 105 fixedly connected to the top of the support table 101.
[0028] It should be noted that when the driven roller 104 moves towards the driving roller 103, the welding wire can be clamped, so that the driving roller 103 can convey the welding wire to the welding area through rotation. The positioning frame 105 is used for limiting the position of the welding wire to avoid the position of the welding wire from deviating.
[0029] The wire changing mechanism 200 comprises a fixed frame 201 fixedly connected to the top of the support table 101 on both sides, a second motor 202 fixedly installed on the outer surface of the fixed frame 201, a connecting column 203 fixedly installed on the output end of the second motor 202 through a shaft coupling, a support rod 204 fixedly connected to the other end of the connecting column 203, a rotating disc 205 fixedly sleeved on the outer surface of the penetrating end of the support rod 204, a bearing frame 206 fixedly installed on the inner surface of the rotating disc 205 on both sides and used in cooperation with the positioning frame 105, and a clamping assembly 207 arranged on the top of the support table 101 and used in cooperation with the driven roller 104.
[0030] It should be noted that the bearing frame 206 is used for loading the welding wire, and the bearing frame 206 is made of carbon fiber reinforced composite material. The carbon fiber reinforced composite material has high rigidity and high friction coefficient, and can generate strong friction force on the contact surface in contact with the welding wire, so that the welding wire can only fall into the positioning frame 105 under the action of gravity without being blocked. When the welding wire in the bearing frame 206 is filled into the positioning frame 105, the operator can use the time when the welding wire is not exhausted to fill new welding wire into the bearing frame 206.
[0031] In addition, a detector 300 is arranged on the top of the support table 101 and used in cooperation with the positioning frame 105.
[0032] It should be further noted that the detector 300 is used for detecting whether the welding wire in the positioning frame 105 is exhausted. When the welding wire is exhausted, the first motor 102 is turned off and the second motor 202 is started through the sensor. After the filling of the welding wire is completed, the output end of the second motor 202 is controlled to rotate reversely and the first motor 102 is turned on, so as to continue conveying the welding wire.
[0033] Specifically, the driving roller 103 is fixedly installed on the top of the support table 101 through a bearing, and the outer surface of the support rod 204 is in rotating contact with the inner surface of the fixed frame 201.
[0034] Further, the clamping assembly 207 comprises a first belt disc 207a fixedly sleeved on the outer surface of the connecting column 203, a belt 207b sleeved on the outer surface of the first belt disc 207a, a second belt disc 207c sleeved on the inner surface of the other end of the belt 207b, and a driving rod 207d fixedly connected to the inner surface of the second belt disc 207c.
[0035] Preferably, the clamping assembly 207 further comprises a first bevel gear 207e fixedly sleeved on the outer surface of the driving rod 207d, a second bevel gear 207f engaged with the outer surface of the first bevel gear 207e, a driven rod 207g fixedly connected to the inner surface of the second bevel gear 207f, and a threaded rod 207h fixedly installed at the other end of the driven rod 207g.
[0036] It should be noted that the clamping assembly 207 further comprises an internal threaded sleeve 207i threadedly connected to the outer surface of the threaded rod 207h, fixed blocks 207j fixedly connected to the outer surface of the internal threaded sleeve 207i on both sides respectively, guide rails 207k fixedly installed on the top of the support table 101 on both sides and cooperating with the fixed blocks 207j, and a mounting box 207l fixedly connected to the top of the support table 101.
[0037] Wherein, through the cooperation of the guide rails 207k and the fixed blocks 207j, the internal threaded sleeve 207i can be limited, so that the internal threaded sleeve 207i can drive the driven roller 104 to move linearly through the rotation of the threaded rod 207h.
[0038] Further, the driven roller 104 is fixedly installed on the top of the internal threaded sleeve 207i through a bearing, and the inner surface of the fixed block 207j is in sliding contact with the outer surface of the guide rail 207k.
[0039] Specifically, the outer surface of the driving rod 207d is in rotational contact with the inner surface of the mounting box 207l, and the outer surface of the driven rod 207g is in rotational contact with the other side of the inner surface of the mounting box 207l.
[0040] In use, when the detector 300 detects that the welding wire in the positioning frame 105 is exhausted, the first motor 102 is turned off and the second motor 202 is turned on through the sensor, the support rod 204, the rotating disc 205 and the first belt disc 207a are synchronously rotated through the second motor 202, the second belt disc 207c, the driving rod 207d and the first bevel gear 207e are rotated through the cooperation of the first belt disc 207a and the belt 207b, the driven rod 207g and the threaded rod 207h are synchronously rotated through the cooperation of the first bevel gear 207e and the second bevel gear 207f, the internal threaded sleeve 207i is limited through the cooperation of the guide rails 207k and the fixed blocks 207j, so that the internal threaded sleeve 207i can drive the driven roller 104 to move linearly through the rotation of the threaded rod 207h.
[0041] When the driven roller 104 moves to a position away from the positioning frame 105, the support rod 204 drives the bearing frame 206 at the top of the rotating disc 205 to rotate to a position aligned with the center of the positioning frame 105, so that the welding wire falls into the positioning frame 105 by gravity, and after the detector 300 detects that the welding wire is filled, the output end of the second motor 202 is reversely rotated to move the driven roller 104 to a position in contact with the surface of the welding wire, and the first motor 102 is turned on to drive the driving roller 103 to rotate to continue conveying the welding wire.
[0042] In summary, through the cooperation between the components in the welding wire feeding mechanism 100 and the welding wire changing mechanism 200 and the detector 300, when the welding wire is exhausted, new welding wire can be automatically loaded into the positioning frame 105 by a single driving source, and the welding wire can be clamped and conveyed to the welding area, so as to ensure the continuity and efficiency of the welding process. Through the single driving source to fill the welding wire, not only the labor cost and the labor intensity of the operator can be reduced, but also the energy consumption can be further reduced, so as to improve the welding operation rate while reducing the overall operation cost of the equipment.
