[0033] The guide rail 33 is connected to the nail driving mechanism 41 , and the driving mechanism 31 is connected to the driving wheel 32 . The driving wheel 32 contacts the nail 100 on the guide rail 33 to drive the nail 100 to move toward the nail driving mechanism 41 .

[0034] The electric control device 2 is connected to the driving mechanism 31 and the gas control mechanism 42 respectively, so that the driving mechanism 31 and the gas control mechanism 42 are started synchronously.

[0035] The feeding device of the automatic feeding nailing equipment of the utility model adopts a driving mechanism to rotate the driving wheel, and the driving wheel and the nails on the guide rail collide with each other, so that the nails move along the guide rail toward the nailing mechanism, thereby feeding the nails to the nailing mechanism. The feeding device is not only simple in structure, easy to maintain, not easy to get stuck, and has low manufacturing cost, but also does not limit the number of nails installed on the guide rail. Compared with the existing nail feeding structure, it can reduce the number of nailing times in the production process, and has high production efficiency.

[0036] In addition, the utility model uses an electric control device to synchronously start the driving mechanism and the pneumatic control mechanism, so that nail feeding and nailing are performed synchronously. Compared with the existing separate control of nail feeding and nailing, the utility model reduces the operating steps, has high production efficiency and high automation.

[0037] Preferably, the driving mechanism 31 is a speed regulating motor. The speed regulating motor can adopt the existing technical structure, which is not described in detail here. The speed regulating motor can adopt the Sai Ya speed regulating motor 25W 220V-4GN-150K.

[0038] Preferably, the gas control mechanism 42 is a solenoid valve. The solenoid valve can adopt the existing technical structure, which is not detailed here. The solenoid valve adopts AirTac solenoid valve 4V210-08 AC220V.

[0039] Preferably, if Figure 3As shown, the feeding device further includes a material pressing assembly, which is arranged above the material guide rail 33, and the driving wheel 32 is arranged below the material guide rail 33. The material pressing assembly and the driving wheel 32 respectively contact with the nails 100 on the material guide rail 33. The driving wheel 32 is preferably a gear. The C-shaped nail sleeve is arranged on the material guide rail. In order to enable the driving wheel to contact with the nails smoothly, so as to effectively drive the row of nails to move along the material guide rail, the utility model is also provided with a material pressing assembly. The material pressing assembly contacts with the top of the nail, and the driving wheel contacts with the bottom of the nail, so as to ensure that effective friction can be generated between the driving wheel and the nail, and the nail can be driven to move when the driving wheel rotates.

[0040] More preferably, the feeding device also includes a coupling 311, a connecting shaft, a bearing and a bearing seat, the bearing is installed on the bearing seat, the connecting shaft is installed on the bearing, the driving wheel 32 is sleeved on the connecting shaft and is relatively fixed to the circumference of the connecting shaft, and the output shaft of the driving mechanism 31 is connected to the connecting shaft through the coupling 311 to drive the connecting shaft to rotate, and the connecting shaft drives the driving wheel 32 to rotate. It has a simple structure, a small size and a low manufacturing cost.

[0041] Specifically, the press assembly includes a press seat 35, a press block 36 and an elastic component 37. The press seat 35 and the press block 36 are movably connected. The two ends of the elastic component 37 are respectively connected to the press seat 35 and the press block 36. The press seat 35 contacts the nail 100 on the guide rail 33 through the elastic component 37. The elastic component 37 is a spring. A connecting rod is provided on the press seat. The press block and the connecting rod are movably connected. The two ends of the elastic component are respectively connected to the connecting rod and the press block, pushing the press block to move upward, so that the press block and the connecting rod move relative to each other and compress the elastic component at the same time. The press block is released, and the press block is reset under the action of the elastic component and pressed on the nail of the guide rail. The nail is pressed against the guide rail under the action of the elastic component, ensuring effective contact between the nail and the driving wheel, so that the driving wheel can effectively drive the nail to move when it rotates.

[0042] Preferably, if Figure 1 As shown, the feeding device further includes a position sensor 34 for detecting whether there is a nail 100 on the guide rail 33, and the position sensor 34 is connected to the electronic control device 2. Preferably, the position sensor 34 is a proximity switch. The position sensor 34 is arranged above the guide rail 33 and on the side of the pressing assembly and the driving wheel 32 away from the nailing mechanism 41. When the position sensor detects that there is no nail on the guide rail, a signal is sent to the electronic control device, and the electronic control device alarms to remind the user to add nails.

[0043] Preferably, if Figure 1-2As shown, the feeding device also includes a material bearing mechanism for bearing nails 100; the material bearing mechanism includes a material seat 5, a nail basin 6 and a guide seat 7, the material seat 5 and the guide seat 7 are respectively mounted on the base 1, the nail basin 6 and the material seat 5 are rotatably connected, and the two ends of the guide seat 7 are respectively connected with the nail basin 6 and the material guide rail 33. The material seat plays the role of supporting the nail basin, and the row of nails is wound around the nail basin, and the row of nails can be extended to the material guide rail through the guide seat. Driven by the driving wheel, the row of nails continuously moves toward the nailing mechanism, and the row of nails pulls the nail basin to rotate. The coordinated arrangement of the nail basin and the guide seat can enable the material bearing mechanism to carry up to more than 20,000 nails. Compared with the existing nails that can only load about 100 nails at a time, the carrying capacity is larger, and workers do not need to frequently install nails, which can reduce the number of nailing times during the production process, and even no nailing is required to meet the requirements of one-time production, and the production efficiency is high.

[0044] Furthermore, the nailing device further comprises a foot switch (not shown) for controlling the gas control mechanism 42, and the foot switch is connected to the electric control device 2. Compared with the existing trigger pulling method, the foot switch allows the user to start the nailing device by foot, thus solving the problems of fatigue caused by holding the device and pulling the trigger for a long time, and high labor intensity.

[0045] Preferably, if Figure 2 As shown, the electric control device includes a controller (not shown), a speed regulator 39 and a time relay (not shown), and the controller is connected to the driving mechanism 31, the speed regulator 39, the time relay and the air control mechanism 42 respectively. The controller is connected to the foot switch. The speed regulator is used to adjust the rotation speed of the driving mechanism. The time relay is used to calculate the time and send a signal to the controller.

[0046] The user presses the foot switch to make the controller control the air control mechanism and the drive mechanism to start. At this time, the air control mechanism is connected to the air source, so that the nailing mechanism drives nails. At the same time, the drive mechanism rotates the drive wheel to transport the nails to the nailing mechanism. The nailing mechanism drives one nail each time the foot switch is pressed. When the foot switch is pressed once, the controller controls the nailing mechanism to drive one nail and controls the drive mechanism to start. From the moment the foot switch is pressed, the time relay starts timing, and after the preset time, the controller controls the drive mechanism to stop operating. Therefore, the user can start nailing and nail feeding at the same time by pressing a button, without the need for separate control, saving labor and time, thereby improving production efficiency and realizing automatic nailing.

[0047] Going further, Figure 2As shown, the nailing device also includes an air control seat 43, and the air control mechanism 42, the air control seat 43 and the nailing mechanism 41 are connected in sequence; the air control mechanism 42 changes the flow direction of the gas in the air control seat 43 through the foot switch to drive the nailing mechanism 41. When the foot switch is pressed, the air control mechanism causes the gas to flow in one direction in the air control seat, and the nailing mechanism realizes the nail clamping action under the action of air pressure; when the foot switch is released, the air control mechanism causes the gas to flow in the opposite direction in the air control seat, and the nailing mechanism releases the nail under the action of air pressure, so that the nail is separated from the nailing device, and the nailing is completed.

[0048] Specifically, Figure 4-5 As shown, the air control mechanism 42 is provided with an air inlet 421, and the air control seat 43 is provided with a push cavity, a first air port 433, and a second air port 436; the nailing mechanism 41 and the air control seat 43 are movably connected, and the nailing mechanism 41 divides the push cavity into an inlet cavity 431 and a retracting cavity 434; the first air port 433 is connected to the inlet cavity 431, and the second air port 436 is connected to the retracting cavity 434; the air control mechanism 42 connects the air inlet 421 with the first air port 433 or the second air port 436 through a foot switch. Figure 4 As shown, when the foot switch is pressed, the air inlet and the second air port are connected, so that the gas enters the retraction chamber to drive the nailing mechanism to clamp the nail; Figure 5 As shown, when the foot switch is released, the air inlet is connected to the first air port, so that the air enters the inlet cavity to drive the nailing mechanism to loosen the nail, and the nail falls out of the nailing mechanism. Therefore, the foot switch is used to control the change of the air path inside the air control mechanism, thereby changing the direction of the air flow in the air control seat to drive the nailing mechanism.

[0049] Preferably, the air control mechanism 42 is provided with a first air outlet 422 and a second air outlet 423, and the air control seat 43 is provided with a first air duct 432 and a second air duct 435, the first air port 433, the first air duct 432 and the inlet cavity 431 are connected in sequence, and the second air port 436, the second air duct 435 and the exit cavity 434 are connected in sequence; the air control mechanism 42 connects the air inlet 421 and the first air port 433 and the first air outlet 422 and the second air port 436 through a foot switch, or connects the air inlet 421 and the second air port 436 and the second air outlet 423 and the first air port 433.

[0050] like Figure 4 As shown, when the foot switch is pressed, the air inlet, the second air port, the second air channel and the retreat chamber are connected in sequence, and the gas enters the retreat chamber through the air inlet, causing the nailing mechanism to move toward the inlet chamber, and the gas in the inlet chamber flows out from the first air channel, the first air port and the second air outlet in sequence to drive the nailing mechanism to clamp the nails; Figure 5As shown, when the foot switch is released, the air inlet, the first air port, the first air channel and the inlet cavity are connected in sequence, and the gas enters the inlet cavity through the air inlet, causing the nailing mechanism to move toward the retreat cavity, while the gas in the retreat cavity flows out from the second air channel, the second air port and the first air outlet in sequence to drive the nailing mechanism to loosen the nail, and the nail falls out of the nailing mechanism. Therefore, the foot switch is used to control the change of the internal air path of the air control mechanism, thereby changing the gas flow direction in the air control seat to drive the nailing mechanism.

[0051] More specifically, Figure 4-5 As shown, the nailing mechanism 41 includes a nail pushing assembly and a nail clamping assembly, the guide rail 33 is connected to the nail clamping assembly, the nail pushing assembly is movably connected to the air control seat 43, and the nail pushing assembly divides the pushing chamber into an entry chamber 431 and a retreat chamber 434, and the nail pushing assembly drives the nail clamping assembly to nail through the air control mechanism 42. Among them, the nail pushing assembly includes a piston 411, a piston rod 412 and a nail pushing member 413 connected in sequence, and the nail clamping assembly includes a mounting plate and a clamp 414 movably connected to the mounting plate. The piston 411 is arranged in the pushing chamber, and the piston 411 divides the pushing chamber into an entry chamber 431 and a retreat chamber 434. Gas enters the pushing chamber to drive the piston to move back and forth. The piston drives the nail pushing member through the piston rod, so that the nail pushing member and the clamp collide with each other, so that the clamp clamps the nail or loosens the nail to achieve nailing.

[0052] like Figure 4 As shown, when the foot switch is pressed, the air inlet, the second air port, the second air passage and the retreat chamber are connected in sequence, and the gas enters the retreat chamber through the air inlet, causing the piston to move toward the inlet chamber, driving the nail pushing member to collide with the rear end of the clamp, causing the front end of the clamp to clamp the nail, and the gas in the inlet chamber flows out from the first air passage, the first air port and the second air outlet in sequence. Figure 4 The arrow in the middle indicates the direction of gas flow. Figure 5 As shown, when the foot switch is released, the air inlet, the first air port, the first air passage and the inlet cavity are connected in sequence, and the gas enters the inlet cavity through the air inlet, causing the piston to move toward the retreat cavity direction, driving the nail pusher to collide with the front end of the clamp, causing the front end of the clamp to open and the nail to fall out, while the gas in the retreat cavity flows out from the second air passage, the second air port and the first air outlet in sequence. Figure 5 The middle arrow indicates the direction of gas flow. Therefore, the foot switch is used to control the change of the gas path inside the gas control mechanism, thereby changing the gas flow direction in the gas control seat to drive the nailing mechanism.

[0053] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention.
