Description
Technical Field
[0001] This utility model relates to the technical field of nail heads for nailing machines, and in particular to a nail head for a nailing machine that continuously feeds wire. Background Technology
[0002] Traditional nailing machines typically use an intermittent wire feeding method. With this mechanism, after each nailing action, the wire feeding mechanism needs to pause, waiting for the punch to completely leave the wire inlet before resuming wire feeding to accurately deliver the new nail to the designated position inside the nail head. Only then can the nailing process restart. This process involves significant wire feeding pauses, making continuous, uninterrupted wire feeding impossible.
[0003] Furthermore, previous machine heads mostly had a single pressure roller or double pressure roller intermittent wire feeding structure, which was prone to problems such as incomplete wire feeding, broken nails, single nail output, or no nail feeding or no nail output. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a nailing machine head that can form and nail two nail wires at one time without stopping wire feeding, thereby improving work efficiency. By having the punch device cut and bend the flat metal wire into a U-shaped nail, the mechanical linkage enables the wire feeding device to continuously feed the wire, thus making the overall equipment structure move more smoothly.
[0005] This utility model discloses a nail head for a nailing machine with continuous wire feeding, comprising a punch device, a wire feeding device, a punch housing, a cutter, a base, and two sets of conveying pipes. A guide groove is provided inside the punch housing, and the punch device is slidably mounted within the guide groove. The punch device is used to cut flat metal wire into U-shaped nails and to nail them onto cardboard boxes. A spring plate is mounted on the outer wall of the punch housing, and the cutter is mounted on the inner wall of the guide groove. The cutter is used to cut the flat metal wire. The wire feeding device is mounted on the base and is used to convey the flat metal wire. The two sets of conveying pipes are connected between the wire feeding device and the cutter. The wire feeding device passes two flat metal wires through the two sets of conveying pipes. The wires are fed into the cutter, where a punch device cuts and bends two flat metal wires into U-shaped nails. The punch device then staples the two nails onto a cardboard box, achieving the forming and staplering of two nails in one operation, thus improving work efficiency. While the punch device cuts and bends the flat metal wires into U-shaped nails, the mechanical linkage ensures continuous wire feeding, resulting in more coherent and synchronized operation of the entire equipment. The reciprocating motion and mechanical structure design make the equipment more stable, less prone to problems, and extend its service life. The punch device is installed in a guide groove, saving mechanical travel and further improving work efficiency.
[0006] Preferably, the punch device includes a spring device, a driving device, a first punch, a second punch, a wire bending head, a groove, and a first inclined surface. The first punch is slidably mounted in the guide groove by the driving device, and the second punch is slidably mounted on both sides of the first punch by the driving device. Two sets of wire bending heads are slidably mounted on both sides of the punch housing by the spring device. Two sets of grooves are respectively disposed opposite to the two sets of wire bending heads, and two sets of first inclined surfaces are respectively disposed on the outer walls of the two sets of wire bending heads. The wire feeding device operates to cause the two sets of conveying pipes to convey two flat metal wires through the cutter into the two sets of grooves in the guide groove, firstly causing the first... One punch moves forward, and the front end of the first punch, in conjunction with the cutter, two sets of bending heads, and two sets of grooves, cuts and bends the flat metal wire into a U-shaped nail. At the same time, the flat metal wire continues to be fed forward along both sides of the first punch. After the second punch slides forward, the drive device pushes the two sets of bending heads to retract into the guide seat through two sets of first inclined surfaces. Then, the second punch continues to push the nail forward and nail it into the carton. When the second punch and the first punch slide back to their original positions, the two sets of bending heads move back to their original positions through the elastic device. At the same time, the wire feeding device feeds the flat metal wire back into the two sets of grooves, improving the continuity of the action and increasing work efficiency.
[0007] Preferably, the wire feeding device includes a wire feeding seat, a conveying trough, and a wire feeding wheel. The wire feeding seat is installed on the outer wall of the base, the conveying trough is installed on the wire feeding seat, two sets of conveying pipes are connected to the conveying trough, and the wire feeding wheel is rotatably installed on the wire feeding seat. The position of the wire feeding wheel is matched with the conveying trough, and the driving device is used to provide power for the rotation of the wire feeding wheel. Two flat metal wires are conveyed through the two sets of conveying troughs to the inside of the two sets of conveying pipes. After the driving device is running, it drives the wire feeding wheel to rotate, so that the wire feeding wheel and the conveying trough cooperate to convey the flat metal wires, thereby improving the convenience of automatic conveying of flat metal wires.
[0008] Preferably, the elastic device includes two sets of elastic steel sheets, which are respectively installed on both sides of the punch housing. The two sets of elastic steel sheets press the outer walls of the two sets of wire bending heads into contact. The two sets of elastic steel sheets provide elastic pushing force to the two sets of wire bending heads, thereby improving the convenience of automatically moving the two sets of wire bending heads to limit the metal flat wire.
[0009] Preferably, the driving device includes a transmission device, a punch body, a second inclined surface, a rotating shaft, an eccentric disc, a first connecting rod, and a second connecting rod. The punch body is slidably mounted on the guide groove of the punch housing. The outer wall of the punch body is connected to the outer wall of the first punch. The second inclined surface is disposed on the outer wall of the second punch, and the second inclined surface corresponds to the position of the first inclined surface. The rotating shaft is rotatably mounted on the base. The eccentric disc is concentrically mounted on the end of the rotating shaft. The bottom end of the first connecting rod is rotatably mounted on the eccentric position of the outer wall of the eccentric disc. The top end of the first connecting rod is rotatably connected to the outer wall of the second punch. The bottom end of the second connecting rod is concentrically rotatably connected to the bottom end of the first connecting rod. The top end of the second connecting rod is rotatably connected to the outer wall of the punch body. A transmission device is provided to drive the rotation of the wire feeding wheel. When an external power device drives the rotating shaft to rotate, the rotating shaft drives the eccentric disk to rotate. The rotation of the eccentric disk drives the first connecting rod and the second connecting rod to swing, thereby causing the first connecting rod and the second connecting rod to drive the first punch and the second punch to move alternately, realizing the continuous action of cutting, bending, stapling, and moving and resetting the metal flat wire. When the second connecting rod drives the punch body to move, the punch body drives the first punch to move. At the same time, the first punch, in cooperation with the cutter and the wire bending head, cuts the metal flat wire and makes it into U-shaped nails. The second inclined plane, in cooperation with the first inclined plane, pushes the wire bending head to move, improving the transmission effect of the action.
[0010] Preferably, the transmission device includes a first gear and a second gear. The first gear is mounted on the outer wall of the rotating shaft, and the second gear is rotatably mounted on the base via a transmission shaft. The other end of the transmission shaft is driven to transmit power to the wire feeding wheel via a transmission gear. After the rotating shaft rotates, it drives the first gear to rotate. After the first gear rotates, it drives the wire feeding wheel to rotate through the cooperation of the second gear, the transmission shaft, and the transmission gear, thereby achieving the effect of the wire feeding wheel conveying the metal flat wire while the first punch and the second punch are in motion.
[0011] Preferably, it also includes a cardboard conveyor, which is installed on the outer wall of the base and the position of the cardboard conveyor corresponds to the front end position of the first punch and the second punch. By placing the cardboard on the cardboard conveyor, the cardboard is conveyed to the side of the punch housing, thereby facilitating the first punch, the second punch and the cardboard conveyor to cooperate in fixing the nails to the carton, improving the ease of use.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The wire feeding device conveys two flat metal wires to the cutter through two sets of conveying pipes. The punch device cuts and bends the two flat metal wires into U-shaped nails. Then, the punch device nails the two formed nails into the carton, realizing the forming and nailing of two nail wires in one go, improving work efficiency. By making the punch device cut and bend the flat metal wires into U-shaped nails while the mechanical linkage makes the wire feeding device continuously feed wires, the overall equipment structure operates more smoothly and synchronously, and reciprocates. Through the mechanical structure design, it works more stably, is less prone to problems, and has a longer service life. The punch device is installed in the guide groove, saving mechanical stroke and further improving work efficiency. Attached Figure Description
