Description

Technical Field

[0001] This utility model relates to the technical field of punches, and in particular to a punch for a nailing machine head. Background Technology

[0002] As an essential piece of equipment in the cardboard packaging industry, stapling machines are widely used in sealing various types of cartons and boxes. With the rapid development of the packaging industry, higher demands are being placed on the efficiency, precision, and reliability of stapling machines. One of the core components of a stapling machine is the punch mechanism within the machine head, and its performance directly affects the overall working effect of the machine.

[0003] Traditional carton stapling machine punch mechanisms typically include a punch, a drive unit, and transmission components. Driven by the drive unit, the punch performs a series of actions such as thread feeding, forming, and stapling through reciprocating motion, thereby achieving the stapling of the carton. However, existing punch mechanisms still have some shortcomings in design and use.

[0004] The previous nail machine punch mechanism was an integral structure, which was complicated to manufacture and costly to replace. It usually used an intermittent wire feeding method, which affected the normal conveying of the metal flat wire and reduced the convenience of use. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a nailing machine punch that improves the ease of use of the mechanism, reduces the processing complexity of the mechanism, and improves the convenience of disassembly and maintenance.

[0006] This utility model discloses a punch for a nailing machine, comprising a body and a wire bending mechanism. A wire conveying device is provided on the side of the body, a guide groove is provided on the body, and a wire inlet is provided on the side of the body. The wire bending mechanism is installed in the guide groove of the body, and a groove is provided at the top of the wire bending mechanism. It also includes a forming structure, a punch, a moving part, and a pushing part. The punch and the moving part are slidably installed in the guide groove of the body, and the punch and the moving part are fixedly connected. The pushing part is slidably installed on the punch. The punch and the pushing part are respectively provided with forming structures. The forming structures are used to bend the wire into a U-shape and to push and convey the U-shaped wire. The wire conveying device passes the wire through the body. The wire is fed into both sides of the punch through the inlet and passes through the groove at the top of the bending mechanism. Then, the moving part is driven upward by the power mechanism on the punch. The bending mechanism feeds the wire into the bottom of the punch, and the power mechanism drives the punch to slide. After the punch slides downward, it cooperates with the bending mechanism and the machine body to cut the wire. At the same time, the cut wire is bent into a U-shape by the bending mechanism and the forming structure. Then, the pushing part slides forward, which pushes the formed U-shaped wire forward and binds it to the carton. This improves the ease of use of the mechanism. By designing the punch, moving part and pushing part as separate components, the processing complexity of the mechanism is reduced and the convenience of disassembly and maintenance is improved.

[0007] Preferably, the forming structure includes a C-shaped groove and an arc surface. The C-shaped groove is disposed on the inner side wall of the punch, and the pusher slides in contact with the C-shaped groove. The arc surface is disposed at the end of the pusher. When the punch cuts the metal wire in conjunction with the machine body, as the punch continues to move forward, the cut metal wire is bent into a U-shape through the engagement of the bending mechanism and the C-shaped groove. At this time, the U-shaped metal wire is stuck inside the C-shaped groove. Then, the pusher moves forward, causing the arc surface to push the U-shaped metal wire in the C-shaped groove forward and discharge it, thereby enabling the U-shaped metal wire to be used for binding.

[0008] Preferably, it also includes a guide slope, which is set on the outer wall of the punch and corresponds to the wire inlet position of the machine body. When the punch moves forward, it will block the wire inlet of the machine body. By setting the guide slope, it is easy to avoid the situation where the punch blocks the wire inlet, so that the wire can be fed at the same time when the punch moves forward, reducing work interference and improving wire feeding efficiency.

[0009] Preferably, it also includes a first connecting shaft and a second connecting shaft. The first connecting shaft is disposed at the bottom of the outer wall of the pusher, and the second connecting shaft is disposed at the bottom of the outer wall of the moving member. By providing the first connecting shaft and the second connecting shaft, it is easier for the power mechanism on the machine body to drive the moving member and the pusher to move, thereby improving the convenience of mechanism installation.

[0010] Preferably, it also includes multiple sets of bolts, which are screwed together between the punch and the moving part; by using multiple sets of bolts to fix the punch and the moving part, the convenience of loading and unloading operations of the mechanism is improved.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The metal wire conveying device feeds the metal wire into the front of the punch through the wire inlet of the machine body, and makes the metal wire pass through the groove at the top of the bending mechanism. Then, the moving part is driven forward by the power mechanism on the machine body, which drives the punch to slide. After the punch slides forward, it cooperates with the bending mechanism and the machine body to cut the metal wire. At the same time, the cut metal wire is bent into a U-shape through the cooperation of the bending mechanism and the forming structure. Then, by sliding the pushing part forward, the pushing part pushes the formed U-shaped metal wire forward and binds it to the carton, which improves the ease of use of the mechanism. By designing the punch, moving part and pushing part as separate components, the processing complexity of the mechanism is reduced and the convenience of disassembly and maintenance is improved.

[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0021] like Figures 1 to 7 As shown, the present invention discloses a punch for a nailing machine, comprising a body 1 and a wire bending mechanism 2. A wire conveying device is provided on the side of the body 1, a guide groove is provided on the body 1, and a wire inlet is provided on the side of the body 1. The wire bending mechanism 2 is installed in the guide groove of the body 1, and a groove is provided at the top of the wire bending mechanism 2. The device also includes a forming structure, a punch 3, a moving part 4, and a pushing part 5. The punch 3 and the moving part 4 are slidably installed in the guide groove of the body 1, and the punch 3 and the moving part 4 are fixedly connected. The pushing part 5 is slidably installed on the punch 3. The punch 3 and the pushing part 5 are respectively provided with forming structures. The forming structures are used to bend the wire into a U-shape and to push and convey the U-shaped wire.

[0022] like Figure 1 As shown, the forming structure includes a C-shaped groove 6 and an arc surface 7. The C-shaped groove 6 is disposed on the inner side wall of the punch 3, and the pusher 5 slides in conjunction with the C-shaped groove 6. The arc surface 7 is disposed at the end of the pusher 5.

[0023] In this embodiment, the wire feeding device feeds the wire into both sides of the punch 3 through the wire inlet of the machine body 1, and makes the wire pass through the groove at the top of the bending mechanism 2. Then, the power mechanism on the machine body 1 drives the moving part 4 to slide upward, which in turn drives the punch 3 to slide upward. At the same time, the bending mechanism feeds the wire into the front of the punch 3. After sliding, it cooperates with the bending mechanism 2 and the machine body 1 to cut the wire. The cut wire is then bent into a U-shape by the bending mechanism 2 and the forming structure. Then, by sliding the pusher 5 forward, the pusher 5 pushes the formed U-shaped wire forward and attaches it to the carton, improving the ease of use of the mechanism. By designing the punch 3, the moving part 4 and the pusher 5 as separate components, the processing complexity of the mechanism is reduced and the convenience of disassembly and maintenance is improved. Example 2

[0024] Based on Example 1, such as Figure 4 As shown, the punch head of the nailing machine of this utility model also includes a guide slope 8, which is disposed on the outer wall of the punch 3 and corresponds to the wire inlet position of the machine body 1.

[0025] like Figure 5As shown, it also includes a first connecting shaft 9 and a second connecting shaft 10. The first connecting shaft 9 is disposed at the bottom of the outer side wall of the pusher 5, and the second connecting shaft 10 is disposed at the bottom of the outer side wall of the moving member 4.

[0026] like Figure 3 As shown, it also includes multiple sets of bolts 11, which are screwed together between the punch 3 and the moving part 4;

[0027] In this embodiment, after the punch 3 cuts the metal wire in cooperation with the machine body 1, as the punch 3 continues to move forward, the cut metal wire is bent into a U-shape through the cooperation of the wire bending mechanism 2 and the C-shaped groove 6. At this time, the U-shaped metal wire is stuck inside the C-shaped groove 6. Then, the pusher 5 moves forward, and the arc surface 7 pushes the U-shaped metal wire in the C-shaped groove 6 forward and discharges it, so that the U-shaped metal wire can be used for binding. When the punch 3 moves forward, it will block the wire inlet of the machine body 1. By setting the guide slope 8, it is easy to avoid the situation where the punch 3 blocks the wire inlet, so that the punch 3 can feed the wire while moving forward, reduce work interference, and improve the wire feeding processing efficiency.

[0028] This utility model discloses a punch for a carton stapling machine. During operation, a metal wire is fed into the front of the punch 3 through the wire inlet of the machine body 1 and passes through the groove at the top of the wire bending mechanism 2. Then, the power mechanism on the machine body 1 drives the moving part 4 to slide forward, causing the moving part 4 to drive the punch 3 to slide. After the punch 3 slides forward, it cooperates with the wire bending mechanism 2 and the machine body 1 to cut the metal wire. At the same time, the cut metal wire is bent into a U-shape through the cooperation of the wire bending mechanism 2 and the forming structure. Then, by sliding the pushing part 5 forward, the pushing part 5 pushes the formed U-shaped metal wire forward and staples it onto the carton.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
