[0040] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0041] An automatic nailing device for special-shaped nails, comprising a main seat 1 and an adjusting seat 2, wherein the main seat 1 is installed above the adjusting seat 2, the fixed end of the main seat 1 is hinged to the fixed end of the adjusting seat 2 through a rotating shaft 3, and the movable end of the main seat 1 can reciprocate and rotate around the rotating shaft 3;

[0042] The main seat 1 includes a mounting plate 11 and a nailing assembly 14, wherein the nailing assembly 14 is mounted on the top of the mounting plate 11, and the nailing assembly 14 is used to fire the special-shaped nails 4; the adjustment seat 2 includes a support plate 21, a mounting support 22 and an adjusting rod 23, wherein the mounting support 22 is mounted on the top of the movable end of the support plate 21, and the nailing plate 5 is detachably mounted on the mounting support 22, and the nailing assembly 14 can reciprocately act on the nailing plate 5 through the rotating shaft 3, and the adjusting rod 23 can move up and down through the movable end of the support plate 21, and the adjusting rod 23 is used to adjust the lowest point of the rotation and descent of the main seat 1.

[0043] The existing automatic pneumatic nail guns are often suitable for a single type of nailing board. If nailing boards of different specifications need to be nailed, automatic pneumatic nail guns of different specifications are required, resulting in poor applicability of the automatic pneumatic nail guns. In particular, when special-shaped nails need to be nailed to the nailing boards, a special automatic pneumatic nail gun is required for nailing.

[0044] In order to effectively improve the applicability of the automatic nailing device, the present technical solution proposes an automatic nailing device for special-shaped nails, such as Figure 1-12 As shown, it includes a main seat 1 and an adjustment seat 2. The main seat 1 is installed above the adjustment seat 2. The fixed end of the main seat 1 is hinged to the fixed end of the adjustment seat 2 through the rotating shaft 3, so that an angle is formed between the fixed end of the main seat 1 and the fixed end of the adjustment seat 2. The movable end of the main seat 1 can reciprocate and rotate around the rotating shaft 3. When nailing, the movable end of the main seat 1 rotates and descends around the rotating shaft 3, and nails at the nailing position on the nailing plate 5. After nailing, the movable end of the main seat 1 rotates and rises around the rotating shaft 3, and the nailing plate 5 moves to the next nailing position. The movable end of the main seat 1 rotates and descends around the rotating shaft 3, and nails at the nailing position on the nailing plate 5, and so on. The main seat 1 in this technical solution can rotate reciprocally around the rotating shaft 3 to cooperate with the nailing process, which is conducive to proofreading the nailing position during the nailing process to ensure effective nailing, and at the same time can effectively avoid damage caused by the movement of the nailing plate 5 after nailing.

[0045] The main seat 1 includes a mounting plate 11 and a nailing assembly 14, which is installed on the top of the mounting plate 11 and is used to fire the special-shaped nails 4; the adjustment seat 2 includes a support plate 21, a mounting bracket 22 and an adjusting rod 23, the mounting bracket 22 is installed on the top of the movable end of the support plate 21, and the nailing plate 5 is detachably installed on the mounting bracket 22. The nailing assembly 14 can reciprocate on the nailing plate 5 through the rotating shaft 3, and the adjusting rod 23 can move up and down and penetrate the movable end of the support plate 21. The adjusting rod 23 is used to adjust the lowest point of the rotation and descent of the main seat 1.

[0046] The adjustment process of an automatic nailing device for special-shaped nails of the present technical solution is as follows: first, the nailing plate 5 is detachably mounted on the mounting support 22, and the extension length of the adjustment rod 23 relative to the support plate 21 is adjusted according to factors such as the size of the nailing plate 5, the nailing position on the nailing plate 5, and the installation relationship between the special-shaped nail 4 and the nailing plate 5, so as to effectively adjust the lowest point of the main seat 1 rotating and descending during nailing, and ensure effective nailing. By adding an adjustment seat 2 to the automatic nailing device, the present technical solution can, on the one hand, effectively improve the nailing diversity of the automatic nailing device by installing nailing plates of different sizes on the mounting support 22, and on the other hand, can adjust the extension length of the adjustment rod 23 relative to the support plate 21 according to factors such as the size of the nailing plate 5, the nailing position on the nailing plate 5, and the installation relationship between the special-shaped nail 4 and the nailing plate 5, so as to effectively adjust the lowest point of the main seat 1 rotating and descending during nailing, and ensure effective nailing, which is conducive to improving the applicability of the automatic nailing device.

[0047] Further, the main seat 1 also includes a driving member 15, which is installed on the top of the mounting plate 11, and the output shaft of the driving member 15 is connected to the support plate 21. The driving member 15 is used to drive the movable end of the main seat 1 to reciprocate and rotate around the rotating shaft 3.

[0048] In one embodiment of the present technical solution, the main seat 1 further includes a driving member 15, which is mounted on the top of the mounting plate 11. The output shaft of the driving member 15 is connected to the support plate 21. The driving member 15 is used to drive the movable end of the main seat 1 to reciprocate and rotate around the rotating shaft 3. When nailing, the driving member 15 drives the movable end of the main seat 1 to rotate and descend around the rotating shaft 3, and aligns with the nailing position on the nailing plate 5 to nail. After nailing, the driving member 15 drives the movable end of the main seat 1 to rotate and ascend around the rotating shaft 3, and the nailing plate 5 moves to the next nailing position. The driving member 15 drives the movable end of the main seat 1 to rotate and descend around the rotating shaft 3, and aligns with the nailing position on the nailing plate 5 to nail again. This is done by analogy, which is conducive to ensuring the effective rotation of the main seat 1, thereby ensuring effective nailing, while avoiding damage caused by the movement of the nailing plate after nailing.

[0049] Preferably, the driving member 15 is a driving cylinder.

[0050] To further explain, the adjustment seat 2 also includes a reset member 24, which is installed on the movable end of the support plate 21, and one end of the reset member 24 abuts against the upper surface of the support plate 21, and the other end of the reset member 24 abuts against the lower surface of the mounting plate 11.

[0051] In another embodiment of the present technical solution, the adjustment seat 2 also includes a reset member 24, which is installed on the movable end of the support plate 21, and one end of the reset member 24 is against the upper surface of the support plate 21, and the other end of the reset member 24 is against the lower surface of the mounting plate 11.

[0052] The driving member 15 and the reset member 24 in the technical solution cooperate to complete the rotation of the main seat 1. Specifically, when nailing, the driving member 15 works to drive the movable end of the main seat 1 to rotate and descend around the rotating shaft 3, and nails at the nailing position on the nailing plate 5. After nailing, the driving member 15 does not work, and the movable end of the main seat 1 rotates and rises around the rotating shaft 3 under the action of the reset member 24, and the nailing plate 5 moves to the next nailing position. The driving member 15 works to drive the movable end of the main seat 1 to rotate and descend around the rotating shaft 3, and nails at the nailing position on the nailing plate 5 again, and so on. In the technical solution, the driving member 15 and the reset member 24 cooperate to complete the rotation of the main seat 1, which can effectively save energy and production costs.

[0053] Further, the adjustment seat 2 further includes a buffer component 25, which is installed at the movable end of the support plate 21, and the buffer component 25 is used to slow down the shaking of the main seat 1;

[0054] The buffer assembly 25 includes a buffer seat 251 , a piston barrel 252 and a piston rod. The piston barrel 252 is installed on the buffer seat 251 . The piston rod is slidably installed on the piston barrel 252 . The top of the piston rod acts on the upper surface of the mounting plate 11 .

[0055] In order to reduce the shaking when the main seat 1 rotates and rises, the adjustment seat 2 of the present technical solution also includes a buffer assembly 25, and the buffer assembly 25 is installed on the movable end of the support plate 21. Specifically, the buffer assembly 25 includes a buffer seat 251, a piston barrel 252 and a piston rod, the piston barrel 252 is installed on the buffer seat 251, the piston rod is slidably installed on the piston barrel 252, and the top of the piston rod acts on the upper surface of the mounting plate 11. When the main seat 1 rotates and rises, the top of the piston rod abuts against the upper surface of the mounting plate 11. Since the piston rod is slidably installed on the piston barrel 252, the cooperation of the piston rod and the piston barrel 252 can reduce the shaking caused by the instantaneous lifting of the driving member 15 or the shaking caused by the elastic force of the reset member 24 when the main seat 1 rotates and rises, which is beneficial to prolonging the service life of the automatic nailing device.

[0056] Preferably, the buffer assembly 25 includes the buffer seat 251 and a hydraulic buffer, the hydraulic buffer includes the piston barrel 252 and a piston rod, the hydraulic buffer is installed on the buffer seat 251, and the top of the hydraulic buffer acts on the upper surface of the mounting plate 11.

[0057] Further, the main seat 1 also includes a nail feeding assembly 12 and a nail binding assembly 13, both of which are installed on the top of the mounting plate 11, and the nail feeding assembly 12 is used to store and transport the special-shaped nails 4, and the nail binding assembly 13 is used to transport the special-shaped nails 4 to the nailing assembly 14.

[0058] Furthermore, the main seat 1 in the present technical solution also includes a nail feeding assembly 12 and a nail binding assembly 13, both of which are installed on the top of the mounting plate 11. The special-shaped nail 4 enters the automatic nailing device through the nail feeding assembly 12, and then the special-shaped nail 4 is transported from the nail feeding assembly 12 to the nailing assembly 14 through the nail binding assembly 13 to realize the nailing action. The structure is simple and the performance is reliable.

[0059] Further, the nail feeding assembly 12 includes a nail storage box 121 and a nail feeding groove 122, and the nail storage box 121 is used to transport the special-shaped nails 4 to the nail feeding groove 122; the nail feeding groove 122 is connected to the nail output end of the nail storage box 121, and the horizontal height of the nail input end of the nail feeding groove 122 is higher than the horizontal height of the nail output end of the nail feeding groove 122.

[0060] The nail feeding assembly 12 in the present technical solution includes a nail storage box 121 and a nail feeding groove 122. The nail storage box 121 is used to transport the special-shaped nails 4 to the nail feeding groove 122; the nail feeding groove 122 is connected to the nail outlet end of the nail storage box 121, and the horizontal height of the nail inlet end of the nail feeding groove 122 is higher than the horizontal height of the nail outlet end of the nail feeding groove 122, so that after the special-shaped nail 4 is ejected from the nail storage box, it can slide down to its nail outlet end along the inclined nail feeding groove 122 under the action of gravity and / or external force vibration, which is convenient for the next nailing process.

[0061] Preferably, the nail storage box 121 is a fully automatic screw machine. This technical solution uses a fully automatic screw machine as the nail storage box 121, which can store multiple special-shaped nails at the same time and realize the function of automatic nail replenishment and nail feeding, which is conducive to improving the working efficiency of the automatic nailing device.

[0062] Further explained, the stapling assembly 13 includes a stapling support 131 and a stapling push plate 132, the stapling support 131 has a stapling groove 130 inside, and the stapling groove 130 is connected to the stapling feeding groove 122; the stapling push plate 132 is installed in the stapling groove 130, and the stapling push plate 132 can move left and right along the stapling groove 130.

[0063] The staple assembly 13 in the present technical solution includes a staple support 131 and a staple push plate 132 . A staple groove 130 is provided inside the staple support 131 , and the staple groove 130 is communicated with the staple feeding groove 122 . The staple push plate 132 is installed in the staple groove 130 , and the staple push plate 132 can move left and right along the staple groove 130 .

[0064] Specifically, Figure 7-8 As shown, when the nail pushing plate 132 moves toward the nail driving assembly 14, it pushes the special-shaped nail 4 to fall into the nail dropping groove 1411 for nailing, and the nail pushing plate 132 fills the gap in the nailing groove 130 to avoid multiple special-shaped nails 4 entering the nailing groove 130 at the same time, ensuring that the nail driving assembly 14 only drives one nail at a time, effectively ensuring that the automatic nailing device performs normal nailing; when the nail pushing plate 132 moves away from the nail driving assembly 14, a gap is left in the nailing groove 130, and the special-shaped nail 4 located in the nail feeding groove 122 falls into the nailing groove 130 under the action of gravity and / or external force vibration to complete the nailing action, and so on.

[0065] Preferably, the stapling assembly 13 further includes a driving seat 133, and the driving seat 133 is used to drive the nail pushing plate 132 to move left and right along the stapling slot 130. More preferably, the driving seat 133 is a driving cylinder.

[0066] To further illustrate, the nailing assembly 14 includes a nailing barrel 141, a striker 142 and a nailing head, wherein the striker 142 is movably disposed on the top of the nailing barrel 141, and the nailing head is sleeved on the bottom of the nailing barrel 141;

[0067] A nail dropping groove 1411 is provided inside the nail barrel 141, and the nail dropping groove 1411 is communicated with the nailing groove 130, and a nailing groove 1441 is provided inside the nail head, and the nailing groove 1441 is communicated with the nail dropping groove 1411, and the striker 142 can move up and down along the nail dropping groove 1411 and the nailing groove 1441.

[0068] The nailing assembly 14 in the present technical solution includes a nailing barrel 141, a firing pin 142 and a nailing head.

[0069] Since the nail dropping groove 1411 and the nail loading groove 130 are interconnected, when the special-shaped nail 4 is pushed to the nail output end of the nail loading groove 130 by the nail pushing plate 132, the special-shaped nail 4 will fall into the nail dropping groove 1411 and the nail driving groove 1441 in sequence under the action of gravity and / or external force vibration. After the special-shaped nail 4 falls into the nail dropping groove 1441, the firing pin 142 slides down along the nail dropping groove 1411 to the nail driving groove 1441, and fires the special-shaped nail 4 to complete the nail driving action. The structure is simple and the performance is reliable.

[0070] Preferably, the nailing assembly 14 further includes a firing member 146, and the firing member 146 is used to drive the firing pin 142 to move up and down along the nail dropping groove 1411 and the nailing groove 1441. More preferably, the firing member 146 is a firing cylinder.

[0080] Nailing completion state: the firing pin 142 descends and slides down the nail drop groove 1411 to the nail driving groove 1441, and fires the special-shaped nail 4 to complete the nail driving action, and the guide piece 144 is in the extended state.

[0081] After nailing is completed, the striker 142 retracts and rises to the original position along the nail drop groove 1411, and the guide piece 144 contracts and is in a closed state again, waiting for the next special-shaped nail 4 to fall in.

[0082] To further explain, the nailing groove 1441 is opened inside the guide plate 144, and the nailing groove 1441 includes a guide part 102 and a calibration part 103 which are sequentially connected from top to bottom, and the cross-sectional shape of the guide part 102 is an inverted isosceles trapezoid, and the lower base length of the guide part 102 is greater than the diameter of the nailing groove 1411, and the upper base length of the guide part 102 is equal to the diameter of the calibration part 103.

[0083] In one embodiment of the present technical solution, a nailing groove 1441 is provided inside the guide plate 144, and the nailing groove 1441 is divided into a guide portion 102 and a calibration portion 103 from top to bottom; the cross-sectional shape of the guide portion 102 is an inverted isosceles trapezoid, and the side length of the lower bottom of the guide portion 102 (i.e., the longer bottom side of the guide portion 102) is greater than the diameter of the nailing groove 1411, which can effectively ensure that when the special-shaped nail 4 enters the guide plate 144, no matter what distorted position the special-shaped nail 4 is in, it can be re-guided to ensure effective nailing; the side length of the upper bottom of the guide portion 102 (i.e., the shorter bottom side of the guide portion 102) is equal to the diameter of the calibration portion 103, so that the nail tip of the special-shaped nail 4 can be stably accommodated in the calibration portion 103, further ensuring effective nailing.
