Description

Technical Field

[0001] This application relates to the field of wood processing equipment technology, and in particular to a pneumatic coil nail gun. Background Technology

[0002] In the production of wooden packaging such as pallets and crates, it is often necessary to nail two or more layers of wood boards together to ensure the stability and load-bearing capacity of the structure. During production, the length of the nails is often greater than the total thickness of the multi-layered wood boards, and the nails inevitably penetrate the wood, leaving nail tips protruding. The existing method of handling this is to turn the board over after the nails penetrate the wood board and then manually bend the protruding nail tips. Workers need to handle the protruding nail tips one by one, which requires a lot of manpower and time and is inefficient. Summary of the Invention

[0003] In view of this, this application proposes a pneumatic coil nail gun, comprising: a base, a back plate, a movable plate, a coil nail gun, and a reverse nail plate;

[0004] The back panel is mounted vertically on the base.

[0005] The movable plate is movably mounted on the back plate, and the movable plate can reciprocate in the direction toward or away from the base;

[0006] The coil nail gun is mounted on the movable plate, with the nozzle of the coil nail gun facing the base;

[0007] The anti-nail plate is movably mounted on the base so that when the coil nail gun moves down, the anti-nail plate is displaced to below the nozzle of the coil nail gun;

[0008] The coil nail gun has a preset angle α between its gun axis and the length of the moving plate; so that when the coil nail gun performs nailing operations, the nails penetrate the wooden board at an angle and then strike the anti-nail plate to achieve automatic bending.

[0009] In one possible implementation, the preset angle α has a value range of 8°–15°.

[0010] One possible implementation also includes a sliding table;

[0011] The base has a sliding groove that matches the slide table, and the slide table is slidably set in the sliding groove; one end of the slide table has a connecting part, and the anti-nail plate is detachably installed on the connecting part.

[0012] In one possible implementation, the main body of the connector is a rectangular plate-like structure.

[0013] In one possible implementation, a sliding guide rail is provided on the back panel; and the sliding guide rail extends along the length of the back panel; the movable plate is slidably mounted on the sliding guide rail.

[0014] In one possible implementation, the sliding guide rail includes: a first guide rail and a second guide rail arranged parallel to each other; a first slider and a second slider are provided on the side of the moving plate facing the back plate, the first slider is slidably connected to the first guide rail, and the second slider is slidably connected to the second guide rail.

[0015] In one possible implementation, a drive device is also included; the drive device is fixedly mounted on the back plate and located between the first guide rail and the second guide rail; the output end of the drive device is connected to the movable plate via a transmission component.

[0016] In one possible implementation, it also includes connectors and fasteners; the connectors are fixedly mounted on the base and located on both sides of the back plate; the fasteners are sequentially installed through the connectors and the back plate.

[0017] In one possible implementation, a first mounting bracket and a second mounting bracket are provided opposite to each other on the movable plate; a coil nail gun is mounted on the first mounting bracket and the second mounting bracket, and the nozzle of the coil nail gun is set through the second mounting bracket.

[0018] In one possible implementation, the anti-nail plate is made of high-hardness steel plate.

[0019] Beneficial effects of this application

[0020] After moving the anti-nail plate below the nozzle of the coil nail gun, the multi-layered wooden board to be processed is placed on the anti-nail plate on the base. The moving plate moves along the length of the back plate towards the base, causing the coil nail gun to move along with the moving plate. When the coil nail gun on the moving plate moves to the position to be nailed, the pneumatic coil nail gun is activated. The nail penetrates the wooden board at an angle and hits the anti-nail plate. The nail tip collides with the anti-nail plate. At the moment of collision, the nail tip is subjected to a reaction force applied by the anti-nail plate. Since the point of collision between the nail tip and the anti-nail plate is deviated from the axis of the nail, there is a vertical distance (i.e., lever arm) between the point of application of the reaction force and the axis of the nail. Under the combined action of the reaction force and the lever arm, a torque is generated. The torque forces the nail tip to bend with the position closest to the nail tip at the point of contact between the nail and the wooden board as the fulcrum, thereby realizing the automatic bending of the nail tip.

[0021] This application sets up a coil nail gun and a reverse nail plate, with a preset angle α between the axis of the coil nail gun and the length direction of the moving plate. The coil nail gun and the reverse nail plate work together, so that when the coil nail gun is used for nailing, the nail penetrates the wooden board at an inclined angle and hits the reverse nail plate to generate a torque, thereby forcing the nail tip to bend automatically. Compared with the traditional method of manually bending the nail tips one by one, the worker only needs to operate the pneumatic coil nail gun to complete the nailing work and the bending of the nail tip. There is no need for a lot of manual operation on the remaining nail tips, which shortens the nail tip processing time, improves work efficiency, and reduces labor costs.

[0022] By movably mounting the movable plate on the back plate, the reciprocating motion of the movable plate in the direction toward or away from the base drives the coil nail gun to reciprocate, thereby adjusting the distance between the coil nail gun and the anti-nail plate. This allows the pneumatic coil nail gun of this application to nail wooden boards of different thicknesses, improving the versatility of the pneumatic coil nail gun.

Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0036] This application proposes a pneumatic coil nail gun, such as Figures 1 to 5 As shown, the system includes: a base 100, a back plate 200, a movable plate 300, a coil nail gun 210, and a reverse nail plate 110. The back plate 200 is vertically mounted on the base 100, and the movable plate 300 is movably mounted on the back plate 200, and the movable plate 300 can reciprocate in a direction toward or away from the base 100. The coil nail gun 210 is disposed on the movable plate 300, and the nozzle of the coil nail gun 210 is positioned toward the base 100. The reverse nail plate 110 is movably mounted on the base 100 so that when the coil nail gun 210 moves downward, the reverse nail plate 110 is displaced to below the nozzle of the coil nail gun 210. A preset angle α is provided between the axis of the coil nail gun 210 and the length direction of the movable plate 300 so that when the coil nail gun 210 performs nailing operations, the nails penetrate the wooden board at an angle and then strike the reverse nail plate 110 to achieve automatic bending.

[0037] It should be noted that the base 100 provides stable support for the entire equipment, preventing the pneumatic coil nail gun from shaking or tipping over during operation. The back plate 200 is fixedly mounted on the base 100, and the length direction of the back plate 200 is perpendicular to the plane of the base 100. The back plate 200 provides a vertical positioning reference for the movable plate 300, allowing the movable plate 300 to reciprocate along the length direction of the back plate 200. The movable plate 300 provides a secure mounting position for the coil nail gun 210, ensuring that the coil nail gun 210 will not shake or fall during movement. By movably mounting the movable plate 300 on the back plate 200, the reciprocating movement of the movable plate 300 towards or away from the base 100 drives the reciprocating movement of the coil nail gun 210, thereby adjusting the coil nail gun 210 relative to the base 100. The distance between the anti-nail plates 110 allows the pneumatic coil nail gun of this application to nail boards of different thicknesses, improving the versatility of the pneumatic coil nail gun; the coil nail gun 210 is suitable for quickly and accurately nailing nails into the board; the board is placed on the anti-nail plates 110, which are designed to provide a reaction force to force the nail tip to bend; the anti-nail plates 110 are movably positioned so that they can be accurately moved below the muzzle of the coil nail gun 210, so that the nail impacts the anti-nail plate 110 after penetrating the board, thereby achieving the bending treatment of the nail tip; the gun body axis and the moving plate 300 are provided with a preset angle α, so that the nail penetrates the board at an inclined angle; this inclined nailing method helps to impact the anti-nail plate 110 at a suitable angle after the nail penetrates the board, thereby achieving automatic bending of the nail tip.

[0038] After the anti-nail plate 110 is moved below the nozzle of the coil nail gun 210, the multi-layered wood board to be processed is placed on the anti-nail plate 110 on the base 100. To ensure the multi-layered wood board is stably placed on the anti-nail plate 110, it can be fixed by setting up existing auxiliary fixing equipment or by manual straightening; this application does not limit this method. The moving plate 300 moves along the length of the back plate 200 towards the base 100, causing the coil nail gun 210 to move along with the moving plate 300. When the coil nail gun 210 on the moving plate 300 moves to the position to be nailed, it is activated. In a pneumatic coil nail gun, the nail penetrates the wooden board at an angle and strikes a nail-reverse plate 110. The nail tip collides with the nail-reverse plate 110, and at the instant of impact, the nail tip experiences a reaction force from the nail-reverse plate 110. Because the point of impact between the nail tip and the nail-reverse plate 110 is off-axis, there is a perpendicular distance (i.e., a lever arm) between the point of application of the reaction force and the nail axis. The combined action of the reaction force and the lever arm generates a torque. This torque forces the nail tip to bend around the point closest to the nail tip at the point of contact with the wooden board, thus achieving automatic bending of the nail tip. The magnitude of the torque is determined by the magnitude of the reaction force and the length of the lever arm; that is, torque = reaction force × lever arm.

[0039] This application sets up a coil nail gun 210 and a nail-reversing plate 110, and sets a preset angle α between the axis of the coil nail gun 210 and the length direction of the moving plate 300. The coil nail gun 210 and the nail-reversing plate 110 work together so that when the nail penetrates the wooden board at an inclined angle, it hits the nail-reversing plate 110 and generates a torque, thereby forcing the nail tip to bend automatically. Compared with the traditional method of manually bending the nail tips one by one, the worker only needs to operate the pneumatic coil nail gun to complete the nailing work and the bending of the nail tip. There is no need for a lot of manual operation on the remaining nail tips one by one, which shortens the nail tip processing time, improves work efficiency, and reduces labor costs.

[0040] In one possible implementation, such as Figure 2 As shown, the preset angle α ranges from 8° to 15°. A suitable preset angle α allows the nail to strike the anti-nail plate 110 at a suitable angle after penetrating the wooden board, generating sufficient torque to ensure that the nail tip can be effectively bent. Preferably, the preset angle α is 10°.

[0041] In one possible implementation, a slide table 120 is also included; a sliding groove is provided on the base 100, and the sliding groove matches the slide table 120; the slide table 120 is slidably disposed in the sliding groove; a connecting part 130 is provided at one end of the slide table 120, and the anti-nail plate 110 is detachably installed on the connecting part 130.

[0042] It should be noted that the base 100 has a sliding groove that extends along the width of the base 100. The sliding groove provides installation space for the slide table 120. The slide table 120 is embedded in the sliding groove of the base 100 and reciprocates along the length of the sliding groove. The cross-section of the slide table 120 is a trapezoidal structure that is narrower at the top and wider at the bottom. The structure of the slide table 120 provides a self-locking effect in the vertical direction. When a nail hits the anti-nail plate 110 and generates an oblique impact force, the force in the vertical direction will cause the slide table 120 to move upward. Due to the trapezoidal structure of the slide table 120, the upward movement will cause the wider bottom of the slide table 120 to engage with the inner wall of the sliding groove to resist the movement of the slide table 120, thereby limiting the position of the slide table 120. Within the sliding groove, the slide table 120 is prevented from shifting due to the impact force generated by the nail, ensuring that the slide table 120 is always stably located within the sliding groove. This, in turn, ensures that the anti-nail plate 110 maintains an accurate position during nail impact. The connecting part 130 is suitable for providing an installation base for the anti-nail plate 110. One end of the connecting part 130 is fixedly connected to the slide table 120. The anti-nail plate 110 is detachably mounted on the end face of the connecting part 130. The movement of the slide table 120 causes the anti-nail plate 110 on the connecting part 130 to move, thereby ensuring that the anti-nail plate 110 is always located below the nozzle of the coil nail gun 210. The detachable design of the anti-nail plate 110 allows workers to easily remove the anti-nail plate 110 from the end face of the slide table 120 for replacement or repair.

[0043] In one possible implementation, the main body of the slide table 120 is a dovetail wedge, and a corresponding dovetail groove is opened in the sliding groove. The slide table 120 and the sliding groove slide in a sliding fit through the wedge-shaped surface, which further enhances the guiding accuracy and anti-overturning capability of the slide table 120.

[0044] In one possible implementation, the main body of the connecting part 130 is a rectangular plate-like structure. The rectangular plate-like structure of the connecting part 130 has a large moment of inertia, which can effectively resist bending and torsional deformation when subjected to the reaction force when the nail hits the anti-nail plate 110, ensuring that the anti-nail plate 110 is fixed in position. At the same time, the connecting part 130 can evenly distribute the impact force transmitted by the anti-nail plate 110 to the slide table 120, avoiding local stress concentration that could cause damage to the connecting part 130.

[0045] In one possible implementation, the connecting part 130 and the slide 120 are integrally molded.

[0046] In one possible implementation, the anti-nail plate 110 is made of high-hardness steel plate.

[0047] In one possible implementation method; such as Figure 1 , Figure 4As shown, a sliding guide rail 400 is provided on the back plate 200; the sliding guide rail 400 extends along the length of the back plate 200, and the movable plate 300 is slidably mounted on the sliding guide rail 400. It should be noted that the sliding guide rail 400 provides a clear movement path for the movable plate 300, ensuring that the movable plate 300 and the coil nail gun 210 can move smoothly along a predetermined direction. The sliding guide rail 400 extends along the length of the back plate 200, ensuring that the movable plate 300 can only slide along the direction of the sliding guide rail 400 (i.e., the Z-axis), preventing the movable plate 300 from deviating during movement. By providing the sliding guide rail 400, the movable plate 300 can slide on the sliding guide rail 400, thereby flexibly adjusting the distance between the movable plate 300 and the base 100, and thus moving the coil nail gun 210 closer to or away from the wooden board placed on the base 100; this allows the pneumatic coil nail gun to easily adapt to wooden boards of different thicknesses.

[0048] In one possible implementation, such as Figure 4 As shown, the sliding guide rail 400 includes: a first guide rail 410 and a second guide rail 420 arranged parallel to each other; the moving plate 300 is provided with a first slider 310 and a second slider 320 on the side facing the back plate 200, the first slider 310 is slidably connected to the first guide rail 410, and the second slider 320 is slidably connected to the second guide rail 420.

[0049] It should be noted that the first guide rail 410 and the second guide rail 420 are arranged opposite to each other on the back plate 200. The parallel and opposite arrangement of the first guide rail 410 and the second guide rail 420 can provide guidance for the movement of the first slider 310 and the second slider 320, ensuring the stability of the moving plate 300 during the movement process and preventing the moving plate 300 from shaking or tilting during the movement. The first slider 310 and the second slider 320 are arranged opposite to each other on the side of the moving plate 300 facing the first guide rail 410 and the second guide rail 420, and the first slider 310 is slidably connected to the first guide rail 410, and the second slider 320 is slidably connected to the second guide rail 420, thereby making the sliding of the sliding plate more stable.

[0050] In one possible implementation, there are two or more first sliders 310 and two or more second sliders 320, and the number of first sliders 310 is the same as the number of second sliders 320; two or more first sliders 310 are arranged sequentially along the axial direction of the first guide rail 410, and two or more second sliders 320 are arranged sequentially along the axial direction of the second guide rail 420, and the first sliders 310 and the second sliders 320 are arranged in a one-to-one correspondence.

[0051] Furthermore, there are two first sliders 310 and two second sliders 320.

[0052] In one possible implementation, a drive device 500 is also included; the drive device 500 is fixedly mounted on the back plate 200 and located between the first guide rail 410 and the second guide rail 420; the output end of the drive device 500 is connected to the movable plate 300 through a transmission component.

[0053] It should be noted that the drive device 500 is used to provide a power source for the reciprocating motion of the moving plate 300. The drive device 500 is fixed on the back plate 200 and placed between the first guide rail 410 and the second guide rail 420, which effectively utilizes the longitudinal space of the back plate 200 and makes the structure of the entire pneumatic nail gun more compact. The output end of the drive device 500 is provided with a transmission part 510. The two ends of the transmission part 510 are respectively connected to the first slider 310 and the second slider 320. The drive device 500 drives the moving plate 300 to move through the transmission part 510, thereby driving the first slider 310 and the second slider 320 to move synchronously, ensuring that the moving plate 300 remains horizontal during the movement and avoiding tilting of the moving plate 300 due to unilateral drive.

[0054] Furthermore, the drive device 500 can use an existing telescopic cylinder, which drives the moving plate 300 to move by extending and retracting the cylinder, thereby causing the first slider 310 and the second slider 320 to slide on the first guide rail 410 and the second guide rail 420; or it can use a servo motor and a matching transmission unit 510, which converts the rotational motion of the servo motor into the linear motion of the slider, thereby driving the moving plate 300 to move and causing the first slider 310 and the second slider 320 to slide on the first guide rail 410 and the second guide rail 420.

[0055] In one possible implementation, such as Figure 1 As shown, it also includes a connector 220 and fasteners; the connector 220 is fixedly mounted on the base 100 and located on both sides of the back plate 200; the fasteners are sequentially installed through the connector 220 and the back plate 200. It should be noted that the main body of the connector 220 has an L-shaped structure, and the opening of the connector 220 faces the base 100. The connector 220 is positioned opposite to the base 100 and is fixedly connected to the base 100. The L-shaped connector 220 has strong bending stiffness and provides a stable support point for the back plate 200, preventing the back plate 200 from loosening under long-term operation or external force, ensuring a firm connection between the back plate 200 and the base 100. By sequentially installing the fasteners through the connector 220 and the back plate 200, the back plate 200 can be quickly and firmly installed on the base 100, ensuring a firm connection between the back plate 200 and the base 100. This design effectively prevents the backplate 200 from loosening during long-term operation or under external force, thus improving the reliability of the equipment.

[0056] Furthermore, the fasteners can be matching bolts and nuts. The bolts are set through the connector 220, the back plate 200 and another connector 220. The nuts are fitted onto the bolts. By tightening the nuts, the bolts and nuts cooperate to provide sufficient fastening force, thereby firmly installing the back plate 200 on the base 100 through the connector 220. The design of the fasteners makes the disassembly and maintenance of the back plate 200 more convenient. The staff only needs to tighten the nuts to disassemble and install the back plate 200, reducing installation time and labor intensity.

[0057] In one possible implementation, such as Figure 1 , Figure 5 As shown, a first mounting bracket 610 and a second mounting bracket 620 are provided opposite to each other on the movable plate 300; a coil nail gun 210 is mounted on the first mounting bracket 610 and the second mounting bracket 620, and the nozzle of the coil nail gun 210 is set through the second mounting bracket 620.

[0058] It should be noted that the first mounting bracket 610 and the second mounting bracket 620 are suitable for mounting the coil nail gun 210 obliquely on the back plate 200; the first mounting bracket 610 includes opposing first frames 611; the main body of the first frame 611 is L-shaped, and the openings of the two first frames 611 face opposite each other, the two first frames 611 are fixedly mounted on the back plate 200, and a first preset distance is provided between the two first frames 611, the top of the coil nail gun 210 is located between the two first frames 611, and a fixing part 612 is provided on the side of the first frame 611 adjacent to the back plate 200, and the top of the coil nail gun 210 is bolted to the fixing part 612 of the first frame 611; the second mounting bracket 620 includes opposing second frames 62... 1. The main body of the second frame 621 is L-shaped, and the openings of the two second frames 621 are arranged facing each other. The two second frames 621 are fixedly installed on the back plate 200, and a second preset distance is provided between the two second frames 621. The middle part of the coil nail gun 210 is located between the two second frames 621, and the nozzle of the coil nail gun 210 passes through the two second frames 621 and is set towards the anti-nail plate 110. The side of the second frame 621 away from the first frame 611 is provided with a receiving part 622. One side of the receiving part 622 is fixedly connected to the second frame 621, and the other side of the receiving part 622 matches the outer contour of the middle part of the coil nail gun 210. The middle part of the coil nail gun 210 is placed on the receiving part 622, and the middle part of the coil nail gun 210 is fixedly connected to the receiving part 622.
