[0038] Embodiment 1:

[0039] Combination Figure 1-Figure 8 , an automatic continuous stapling device, comprising

[0040] The nail changing mechanism 200 includes a first driving source 201, at least one transmission module and a nail pin push plate 204. The first driving source 201 pushes the nail pin push plate 204 to move horizontally through the transmission module. The nail pin push plate 204 is provided with a nail loading groove 2042, and the nail loading groove 2042 is used for loading rows of nails in batches.

[0041] The nail pressing mechanism 300 includes a second driving source 301 and a pressing plate 302 . The second driving source 301 is connected to the pressing plate 302 , and at least one pressing block 303 is disposed on the pressing plate 302 , and the pressing block 303 is located above the nailing groove 2042 .

[0042] The nail pushing mechanism 400 includes a third driving source 401, a pushing module 402 and a nail pin limiting channel 403. The third driving source 401 is connected to the pushing module 402, and the pushing module 402 moves horizontally in the nail pin limiting channel 403.

[0043] After the nail changing mechanism 200 is loaded with a row of nails, the nail needle pushing plate 204 is driven by the first driving source 201 to approach the nail pressing mechanism 300. The second driving source 301 pushes the pressing plate 302 and drives the pressing block 303 to press the row of nails into the nail needle limiting channel 403. The pushing module 402 pushes the row of nails in the nail needle limiting channel 403 to the set position.

[0044] The above provides an automatic continuous stapling device, which is convenient for realizing the later automatic upgrading of the code nail gun, and can automatically load nails to ensure working efficiency.

[0045] In this embodiment, there are two transmission modules, and the transmission module includes a gear 202 and a rack 203 for meshing transmission. The gear 202 is connected to the output shaft of the first driving source 201, and the rack 203 is fixed on the nail needle pushing plate 204.

A space for nails to fall is reserved between the group of auxiliary support plates 2044, and the nailing groove 2042 is arranged along the length direction of the main support plate 2041.

[0047] Specifically, the main support plate 2041 is provided with notches 2043 , and the notches 2043 are used to fix the racks 203 , so the number of the notches 2043 is the same as the number of the racks 203 .

[0048] In this embodiment, the side wall of the nail pin push plate 204 is provided with a slide groove 2045, and the slide groove 2045 slides along the setting direction of the guide strip 205. Specifically, the cross-sectional shape of the slide groove 2045 and the cross-sectional shape of the guide strip 205 are both trapezoidal, and the slide groove 2045 and the guide strip 205 are interlocked.

[0049] In this embodiment, in order to cooperate with the nail pins in the nail pin limiting channel 403 of the nail pushing mechanism 400, the pushing module 402 pushes the row of nails in the nail pin limiting channel 403 to the set position, and the number of the pressing blocks 303 is 6. In addition, the shape of the pressing blocks 303 is circular, ensuring that the pressing blocks 303 roll and press the row of nails during the forward movement of the row of nails, and preventing the row of nails from jumping in the nail pin limiting channel 403 during the movement, which affects the feeding effect of the nail pushing mechanism 400.

[0050] In this embodiment, the nail pressing mechanism 300 also includes a group of guide columns 304, which are symmetrically arranged on both sides of the second driving source 301, and one end of the guide column 304 abuts against the pressure plate 302. The function of the guide column 304 is to ensure that the pressure plate 302 is lifted and lowered in the vertical direction.

[0051] In this embodiment, the pushing module 402 includes a ball screw, a rotating nut and at least one guide post. The ball screw is connected to the third driving source 401. The rotating nut is sleeved on the ball screw, and the guide post is arranged on the rotating nut. The third driving source 401 drives the ball screw to rotate, and the ball screw converts the rotary motion into a linear motion to drive the rotating nut to move horizontally along the ball screw, and the guide post pushes the row of nails.

[0052] In this embodiment, the nail pushing mechanism 400 also includes a needle head, the needle head and the nail needle limiting channel 403 are connected to each other, and the pushing module 402 pushes the row of needles into the needle head.

[0053] like Fig. 9 As shown, specifically, the needle head includes a needle groove plate 405 and a nail needle pressing plate 406 which are pressed together, and a cavity for a single nail needle is reserved between the needle groove plate 405 and the nail needle pressing plate 406.

[0054] The needle groove plate 405 includes an integrally formed connecting portion 4051 and a head portion 4052. The connecting portion 4051 is plate-shaped, and the head portion 4052 is blade-shaped. The connecting portion 4051 is provided with a nail needle channel 4053, and the shape of the nail needle channel 4053 is a U-shape, and the nail needle channel 4053 is used for passing the nail needle.

[0055] In this embodiment, a nail needle block 404 is arranged between the needle groove plate 405 and the nail needle limiting channel 403, and the nail needle block 404 connects the needle head and the nail needle limiting channel 403, and the nail needle block 404 realizes the transition of the nail needle into the needle head.

[0056] Preferably, the first driving source 201 and the third driving source 401 are both servo motors, which are used to control the operation of mechanical elements; the second driving source 301 is a single-acting cylinder, which converts the pressure energy of compressed air into mechanical energy to drive the mechanical elements to achieve reciprocating linear motion.

[0057] The working principle of this embodiment is as follows:

[0058] After a batch of rows of nails are loaded into the nail loading slot 2042 of the nail changing mechanism 200, the first driving source 201 works to push the nail pin pushing plate 204 to move horizontally, and the nail pin pushing plate 204 drives the row of nails to move horizontally, and then the nail pressing mechanism 300 works, and the second driving source 301 presses the row of nails into the nail pin limiting channel 403 of the nail pushing mechanism 400 until the nail pin limiting channel 403 is filled with the row of nails.

[0059] Then, the third driving source 401 works to push the push module 402 to push the row of nails in the nail pin limiting channel 403 to a set position.

[0060] When the nail pin limiting channel 403 is empty, the nail changing mechanism 200 repeats the above-mentioned operation to fill the nail pin limiting channel 403 with rows of nails.

[0070] The working principle of this embodiment is as follows:

[0071] After a batch of rows of nails are loaded into the nailing groove 2042 of the nail changing mechanism 200, the first driving source 201 works to push the nail needle pushing plate 204 to move horizontally, and the nail needle pushing plate 204 drives the row of nails to move horizontally, and then the nail pressing mechanism 300 works, and the second driving source 301 presses the row of nails into the nail needle limiting channel 403 of the nail pushing mechanism 400, and then the third driving source 401 works, and the pushing module 402 pushes the row of nails in the nail needle limiting channel 403 to the bottom of the nailing mechanism 500, and then the nailing mechanism 500 performs nailing, thereby realizing the work of fast nailing and repairing.
