The above is the entire processing process of the tungsten wire sanding, and the present sanding device realizes fully automatic processing, thereby improving the processing efficiency.

[0035] As shown in the drawings, Figures 2-4As shown, the wire feeding mechanism 1 comprises a first rack 101 and a plurality of wire feeding stations arranged on the first rack 101 and used for continuously feeding tungsten wires. The wire feeding stations are arranged in a cross arrangement to save space. One wire feeding station can continuously feed one tungsten wire. By arranging a plurality of wire feeding stations, multiple tungsten wires can be continuously fed simultaneously in a limited space. The wire feeding station comprises a wire feeding module 103 for continuously feeding the tungsten wire and a tension adjusting module 104 for tensioning the fed tungsten wire. The tungsten wire fed by the wire feeding module 103 is wound on the tension adjusting module 104. During the continuous feeding process, the tungsten wire is tensioned by the tension adjusting module 104 to prevent uneven plating and knotting during the subsequent sand plating process.

[0036] The first rack 101 is further provided with a first fixing frame 105. A plurality of wire arranging wheels 106 are rotatably arranged on the first fixing frame 105 and used for guiding the fed multiple tungsten wires to the same height and arranging them side by side. The number of the wire arranging wheels 106 corresponds to the number of the wire feeding modules 103. The tungsten wire fed by the wire feeding module 103 is wound on the tension adjusting module 104 and then guided by the wire arranging wheel 106, so that the multiple tungsten wires are arranged at a uniform height and equidistantly side by side. The multiple tungsten wires at a uniform height are then tensioned by the tension adjusting module 104, which facilitates the subsequent uniform sand plating process. In addition, the first rack 101 is further provided with a control box 102 for controlling the operation of the wire feeding module 103 and the tension adjusting module 104. The control box 102 can individually control different wire feeding modules 103 to control the number and speed of the tungsten wire feeding. In addition, the control box 102 can also individually control different tension adjusting modules 104 to control the tension of different tungsten wires according to their different tensions, so as to control the tension of different tungsten wires by the tension adjusting module 104, and make the fed tungsten wires all in a tensioned state.

[0037] The wire feeding module 103 comprises a fixing seat 1031 arranged in the first rack 101. An axially and transversely arranged rotating shaft 1032 is rotatably arranged on the fixing seat 1031. A winding drum 1035 with a tungsten wire winding is arranged on the rotating shaft 1032. By controlling the rotating shaft 1032 to rotate clockwise (the rotating direction is taken as the reference), the winding drum 1035 rotates clockwise together, thereby feeding the tungsten wire. Figure 3 In order to drive the rotating shaft 1032 to rotate, the fixing seat 1031 is provided with a mounting seat 10311. A first servo motor 10312 with an output shaft arranged transversely is arranged on the mounting seat 10311. The output shaft of the first servo motor 10312 is connected to one end of the rotating shaft 1032 through a coupling 10313. By operating the first servo motor 10312, the rotating shaft 1032 can be driven to rotate clockwise, thereby feeding the tungsten wire.

[0038] In order to enable the different size of the roll material cylinder 1035 installed on the rotating shaft 1032, the rotating shaft 1032 is fixedly provided with a mounting block 1033, and a pad 1034 is installed on the side of the mounting block 1033 away from the fixed base 1031. A cylindrical fixing member 1037 is further provided on the rotating shaft 1032, and the fixing member 1037 is located on the side of the pad 1034 away from the fixed base 1031. The roll material cylinder 1035 is sleeved on the fixing member 1037. In addition, a thread 1038 is formed on the outer side of the circumference of the fixing member 1037. The fixing member 1037 is provided with a limiting member 1039 for limiting the roll material cylinder 1035 sleeved on the fixing member 1037. The limiting member 1039 is fixed on the fixing member 1037 by the thread 1038, so that the limiting member 1039 is detachably connected with the fixing member 1037. The limiting member 1039 is tightened and cooperates with the pad 1034 to clamp the roll material cylinder 1035. First, the roll material cylinder 1035 is sleeved on the fixing member 1037 and contacts the pad 1034. Then, the limiting member 1039 is screwed on the fixing member 1037. The limiting member 1039 is continuously rotated and moves on the fixing member 1037 towards the pad 1034 under the action of the thread 1038. The roll material cylinder 1035 is clamped on the rotating shaft 1032 by cooperating with the pad 1034. The rotating shaft 1032 drives the roll material cylinder 1035 to perform the unwinding process. When the tungsten wire on the roll material cylinder 1035 is unwound, the limiting member 1039 is unscrewed from the fixing member 1037, so that the roll material cylinder 1035 can be replaced.

[0039] In order to prevent the rotating shaft 1032 from slipping on the rotating shaft 1032 during the driving of the roll material cylinder 1035, a push block 1036 is provided between the roll material cylinder 1035 and the limiting member 1039 and is sleeved on the rotating shaft 1032. The push block 1036 is annular. When the limiting member 1039 is screwed on the fixing member 1037, the push block 1036 is first sleeved on the rotating shaft 1032, so that the push block 1036 contacts the two sides of the roll material cylinder 1035 respectively. Then, the limiting member 1039 is screwed on the fixing member 1037. The limiting member 1039 is rotated to apply force to the push block 1036, so that the roll material cylinder 1035 is clamped between the push block 1036 and the pad 1034. In addition, the push block 1036 and the pad 1034 are rubber blocks or silica gel blocks. Under the action of the rubber elasticity and friction, the roll material cylinder 1035 is clamped and the slipping during the rotation is prevented. In addition, the limiting member 1039 is provided with a handle 10310, so that the worker can more conveniently rotate the limiting member 1039.

[0040] In the embodiment, a support plate 1041 is fixedly arranged on the top of the first rack 101, and a diverting wheel 1047 for diverting the tungsten wire discharged from the winding drum 1035 to the winding wheel 106 is rotatably arranged on the support plate 1041.

[0041] The tension adjusting module 104 comprises a first guide wheel 1042 and a second guide wheel 1043 rotatably arranged on the support plate 1041 and used for guiding the tungsten wire discharged from the winding drum 1035, the tungsten wire discharged from the winding drum 1035 is firstly wound on the first guide wheel 1042 and the second guide wheel 1043 and then wound on the diverting wheel 1047 after the guiding treatment; the tension adjusting module 104 further comprises a swing rod 1044, one end of the swing rod 1044 is rotatably arranged on the support plate 1041, and the other end of the swing rod 1044 is rotatably arranged with a tension wheel 1045 for tensioning the tungsten wire, and a section of the tungsten wire wound between the first guide wheel 1042 and the second guide wheel 1043 is wound on the tension wheel 1045. When the discharged tungsten wire is in a slack state, the swing rod 1044 can be controlled to swing at a specified angle on the support plate 1041, so as to tension the tungsten wire.

[0042] In order to control the swing rod 1044 to swing on the support plate 1041, a second servo motor 1046 is arranged on the support plate 1041, the end of the swing rod 1044 rotatably arranged on the support plate 1041 is fixedly arranged with an output shaft of the second servo motor 1046, and the swing rod 1044 can be driven to swing by the second servo motor 1046; and the second servo motor 1046 is also used for controlling the angle of the swing rod 1044 to swing in real time, so that the tungsten wire is always in a tensioned state.
