Description

Technical Field

[0001] This invention relates to the field of mechanical automation technology, specifically to a device for nailing the right-angled edges of a flexible box / cabinet. Background Technology

[0002] Boxes / containers made of soft materials are used in many fields, such as wooden fruit boxes, cardboard boxes, and thin plastic boxes. Wooden boxes, in particular, are environmentally friendly, reusable, and sturdy enough to be stacked in multiple layers. Therefore, more and more fruit vendors are starting to use wooden fruit boxes to store their fruit.

[0003] However, wooden fruit boxes require nails to attach each side during production. Because the box is three-dimensional and relatively thin, and due to cost constraints, straight nails cannot be used. Therefore, saddle nails are used to attach the sides of the box. These nails require first inserting one leg into one side and then bending the nail to insert it into the other side to complete the attachment of the two sides at right angles. This makes the assembly process inefficient. Summary of the Invention

[0027] In an embodiment of the present invention, the second nail gun 34 includes a second connecting block 341, a second guide rod 342, a second spring 343, and a nail head 344. The nail head 344 is movably disposed within the front housing 31 and is used to bend the nail wire into a bent shape and drive the bent nail into two adjacent sides of the housing.

[0028] In an embodiment of the present invention, the third nail gun 35 includes a third connecting block 351, a third guide rod 352, a third spring 353, and a nail cutting head 354. The nail cutting head 354 is movably disposed within the front housing 31 and is used to cut the incoming nail wire into strips of a fixed length. The third guide rod 352 connects the nail cutting head 354 and the third connecting block 351, and the third spring 353 is sleeved on the third guide rod 352.

[0029] In an embodiment of the present invention, a wire inlet hole 36 is provided at the top of the front housing 31, through which the wire enters the front housing 31. The first connecting block, the second connecting block, and the third connecting block are slidably disposed between two guide blocks 37. Each of the opposite sides of the guide blocks 37 is provided with a guide groove 38. The first connecting block, the second connecting block, and the third connecting block slide within the guide groove 38 to stabilize the first connecting block, the second connecting block, and the third connecting block.

[0030] In an embodiment of the present invention, one end of the first guide rail, the second guide rail, and the third guide rail all pass through a guide rod fixing block 39, and the first spring, the second spring, and the third spring are located on the side of the guide rod fixing block near the guide block.

[0031] In an embodiment of the present invention, the front housing 31 includes a left housing 311 and a right housing 312, and a nail gun channel 313 is formed between the left housing 311 and the right housing 312, and the nail gun channel 313 communicates with the notch 32.

[0032] In an embodiment of the invention, the left housing 311 has a pressure hole 315 near the notch 32, and the front end of the nail-removing plate 334 has a slope 3341. A nail-removing block 3342 is provided in cooperation with the slope 3341. When the nail-removing plate 334 moves forward, the slope 3341 lifts the nail-removing block 3342 upward. The side of the nail-removing block 3342 that contacts the slope 3341 has the same slope. The nail-removing block 3342 is connected to a nail-stopping block 3343, which is movably disposed within the pressure hole 315 and can extend into the nail gun channel 313. Specifically, after the nail-stopping block 3343 enters the nail gun channel 313, it can contact the inner wall of the right housing, blocking the nail gun channel 313 and preventing the cut wire from being ejected from the nail gun channel. The two sides of the nail-stopping block 3343 form right angles towards the notch 32. A return spring 3344 is provided on the outer side of the nail-removing block 3342, and a return baffle 3345 is provided on the outer end of the return spring 3344. Under the pressure of the return spring 3344, the nail-removing block 3342 will always be in the nail gun channel. Driven by the first cam plate, the nail-removing plate will push the nail-removing block 3342 out of the pressure control 313 from the nail gun channel at intervals.

[0033] In an embodiment of the invention, the front end of the nail head 344 has a second notch 3441 facing the nail block 3342, and the edge of the second notch 3441 matches the shape of the nail block 3342.

[0034] In an embodiment of the present invention, the nail cutting head 354 includes an upper cutting head 3541, a lower cutting head 3542, and a connecting rod 3543. The upper cutting head 3541 and the lower cutting head 3542 are both mounted on the connecting rod 3543. The connecting rod 3543 is connected to a third guide rod. The upper cutting head and the lower cutting head are respectively set close to the upper end and the lower end of the nail gun path 313.

[0035] The wire enters the nail gun channel through the wire inlet 36. The upper cutter head 3541 cuts the wire and pushes the cut wire forward to the nail stop block 3343. At the same time, the nail head 344 also moves towards the nail stop block 3343, squeezing the cut wire into a bent shape.

[0036] In an embodiment of the present invention, a rivet gap 3544 is formed between the rivet block 3343 and the upper cutter head 3541 and the lower cutter head 3542. As the upper cutter head and the lower cutter head continue to move toward the notch, the wires extending from the upper and lower sides of the rivet block 3343 are bent by the upper cutter head and the lower cutter head and enter the rivet gap 3544, forming a rivet with a bend in the middle and bends at both ends.

[0037] Subsequently, the floor lifter raises the nail block away from the nail gun path, and the nail head 344 continues to move towards the notch, driving the nail into the two adjacent sides of the housing. The hook rod 73 of the hook assembly 7 moves in opposite directions (i.e., towards the right angle) to bend the exposed top inside the housing, completing the nailing process. Please refer to [link to relevant documentation]. Figure 12The wire is first cut into a 100 state in the nail gun track 313, then bent into a 200 state by the nail head. Next, the upper and lower cutter heads continue to bend the wire into a 300 state. Then, the nail head drives the 300 state nail into the wooden box, and the hook assembly 7 bends the wire (nail) into the final 400 state.
