Description

[0002] The flux-cored wire is also called tubular welding wire, and various special welding materials can be conveniently designed by flexibly adjusting the types and proportions of the core additives.

[0046] One side of the discharging box 1 is fixed with a controller, and the controller is electrically connected with the conveying belt 2 and the motor 42.

[0047] Working principle:

[0048] The medicine powder in the blanking box 1 falls into the conveying belt 2 through the lower material port, and is conveyed to the inside of the filling box 31 for filling. Then, the workpiece 37 in the open state is pulled through the medicine powder in the filling box 31 by other equipment, and the medicine powder is filled into the inside of the workpiece 37. The motor 42 drives the rotating shaft 43 and the rolling wheel 44 to rotate, and the rolling wheel 44 presses the medicine powder into the inside of the workpiece 37 in rotation, discharges the air in the medicine powder, and makes it more compact. After the medicine powder is filled, the workpiece 37 continues to move and passes through the square discharge port 36. In this process, the discharge control plate 33 inserted into the inside of the workpiece 37 adjusts the following height of the medicine powder, so as to accurately control the amount of medicine powder in the workpiece 37.

[0049] The rotating shaft 43 drives the bevel gear two 54 to rotate, the bevel gear two 54 drives the bevel gear one 53 and the reciprocating screw one 52 to rotate, the moving plate one 56 drives the moving plate two 57, the mounting frame 58, the reciprocating screw two 510, the guide rod two 59, the moving frame 512, the one-way gear 511, the triangular block 519 and the V-shaped rubber pad 520 to move to one side. The moving speed is consistent with the pulling speed of the workpiece 37, which ensures that the above-mentioned structure moves synchronously with the workpiece 37 and the medicine powder. During the moving process, the V-shaped rubber pad 520 covers the top of the medicine powder, so as to avoid that the vibration caused by the movement of the workpiece 37 shakes the compacted medicine powder.

[0050] During the moving process, the one-way gear 511 is engaged with the rack two 514, but the rotation direction of the one-way gear 511 cannot drive the reciprocating screw two 510 to rotate in this moving direction, so the moving frame 512 remains at the bottom end of the reciprocating screw two 510. When the one-way gear 511 is disengaged from the engagement with the rack two 514 and is engaged with the rack one 513 after moving a distance, the rotation direction can drive the reciprocating screw two 510 to rotate, and the moving frame 512 moves upward from the bottom end of the reciprocating screw two 510. When moving upward, the two triangular blocks 519 and the V-shaped rubber pad 520 are driven to move away from the workpiece 37, and the workpiece 37 enters the closed top of the forming equipment immediately, so as to wrap the medicine powder inside. During the moving-up process, the compressed spring 517 is released, the top rod 516 is pushed to move downward, the two triangular blocks 519 are rotated around the contact point with the moving frame 512, the opening at the bottom of the triangular block 519 is reduced, the workpiece 37 is prevented from being pulled by friction when moving upward, and the triangular block 519 is facilitated to be pulled out.

[0051] At this time, the first moving plate 56 moves to the end of the first reciprocating screw 52, and the second moving plate 57, the mounting frame 58, the second reciprocating screw 510, the second guide rod 59, the moving frame 512, the one-way gear 511, the triangular block 519 and the V-shaped rubber pad 520 are reset. During the resetting process, the one-way gear 511 meshes with the first rack 513 but cannot drive the second reciprocating screw 510 to rotate, and the moving frame 512 remains at the top end of the second reciprocating screw 510. After moving a distance, the one-way gear 511 meshes with the second rack 514, and the one-way gear 511 can drive the second reciprocating screw 510 to rotate in this moving direction, so that the moving frame 512 pushes the two triangular blocks 519 and the V-shaped rubber pad 520 to move downward. The two triangular blocks 519 are inserted into the top opening of the workpiece 37, and the bottom of the V-shaped rubber pad 520 contacts the powder, and the moving frame 512 extrudes the two triangular blocks 519 to make them open around the connection point. By reducing the bottom opening of the two triangular blocks 519, the insertion of the triangular blocks 519 into the top of the workpiece 37 is avoided. The V-shaped rubber pad presses the powder, guides the powder to gather from the edge to the center, and forms a central bulge in the workpiece, reduces the amount of powder near the edge of the workpiece, and avoids the overflow of the powder from the closed position when extruding into a cylindrical shape, which not only ensures the tightness of the powder, but also prevents the uneven filling caused by the overflow of the powder; at the same time, the V-shaped rubber pad covers the top of the powder, which can avoid the vibration of the workpiece during movement to scatter or overflow the compacted powder.

[0052] When the V-shaped rubber pad 520 contacts the top of the powder, the first moving plate 56 moves in the opposite direction from the end of the first reciprocating screw 52, so that the V-shaped rubber pad 520 and other structures continue to move synchronously with the workpiece 37 according to the above steps.

[0053] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
