Technical Field

[0001] The present invention relates to the technical field of nail gun devices, and more particularly to a pneumatic high-speed nail gun device. Background Art

[0002] In many industrial production and construction scenarios, nailing is a common operation. At present, the existing nail gun equipment on the market has many shortcomings. Traditional handheld nail guns can only load one row of nails at a time. During long-term continuous operation, frequent nailing operations will take a lot of time and seriously affect production efficiency. For example, in large-scale furniture manufacturing workshops, workers use handheld nail guns for nailing work. The capacity of handheld nail guns is small. When the nails in the nail gun are used up, the work will be interrupted and the workers will need to add nails, which greatly affects the production rhythm. Moreover, workers hold nail guns for a long time, the labor intensity is high, and they are prone to fatigue, which in turn affects the quality and efficiency of work.

[0003] Some automatic nail guns, which are simply modified from handheld nail guns, have achieved the automatic nail feeding function to a certain extent, but their size is too large. This makes the size of the matching equipment head also increase accordingly, which not only takes up more working space, but also limits the miniaturization of the equipment and cannot meet some working environments that have strict requirements on the size of the equipment. For example, in decoration work in a small space, large nail guns are difficult to use, resulting in low work efficiency and increased construction difficulty and cost.

[0004] Therefore, it is necessary to invent a pneumatic high-speed nail gun device to solve the above problems. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pneumatic high-speed nail gun device to solve the problem that when using the existing nail gun equipment mentioned in the above background technology, workers have to hold the nail gun for a long time, which has high labor intensity and is prone to fatigue, thereby affecting work quality and efficiency.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pneumatic high-speed nail gun device, comprising an L-shaped nail gun mounting seat and a nail gun body, wherein the nail gun body is fixedly arranged below the L-shaped nail gun mounting seat and is used to quickly drive out the nails inside, a gun nozzle is arranged below the nail gun body, and the gun nozzle is used to guide the nails out and control the number of nails out, a nail storage bin is arranged on the nail gun body, a vertical bin nail space is arranged inside the nail storage bin for storing spare nails, a nail pushing mold is arranged below the nail storage bin, a nail pushing cylinder is arranged at the bottom of the side of the nail storage bin, the output end of the nail pushing cylinder is fixedly connected with the nail pushing mold and is used to drive the nail pushing mold to push the nails in the nail storage bin to automatically feed, a nail gun control air inlet is fixedly arranged on the outer side of the top of the nail gun body, and a compressed air inlet is also arranged on the back of the nail gun body;

[0007] As a further description of the above technical solution, a control valve core, a striker piston, an air storage chamber 1, an air storage chamber 2, an air storage chamber 3 and an air storage chamber 4 are arranged inside the nail gun body, the control valve core is located below the air storage chamber 2, the striker piston is slidably arranged inside the control valve core, the air storage chamber 1 is communicated with the compressed air inlet, the air storage chamber 2 is located at the top of the nail gun body and is communicated with the nail gun control air inlet, the air storage chamber 3 is located above the control valve core and is communicated with the top of the control valve core for pushing the striker piston to move to drive out nails, the air storage chamber 4 is located on one side of the control valve core and is communicated with the bottom of the control valve core for assisting the striker piston in resetting;

[0008] As a further description of the above technical solution, a cylinder hole 1 and a cylinder hole 2 are further provided inside the nail gun body, the cylinder hole 1 is opened at the top of the air storage chamber 4, and the air storage chamber 4 is connected to the air storage chamber 3 through the cylinder hole 2;

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The pneumatic high-speed nail gun device of the present invention has an adjustable nailing speed. Compared with the traditional handheld nail gun, the single nailing interval time is greatly shortened. Its automatic nail feeding function and nail storage bin design reduce the nailing time and the frequency of workers' work interruption caused by nailing, making the production process more continuous and efficient.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1-3 As shown, a pneumatic high-speed nail gun device of this embodiment includes an L-shaped nail gun mounting seat 1 and a nail gun body 2. The L-shaped nail gun mounting seat 1 is used to realize the installation and fixation of the nail gun body 2 to ensure the stability of the nail gun body 2 during the working process. The nail gun body 2 is arranged below the L-shaped nail gun mounting seat 1, and a gun nozzle 3 is arranged below the nail gun body 2. The gun nozzle 3 is used for guiding nail output and controlling the number of nails output. The shape and size of the gun nozzle 3 are designed to adapt to nails of different specifications. A nail pushing mold 5 is arranged below the gun nozzle 3, and a nail storage bin 4 is arranged on the nail gun body 2. This layout design is reasonable, which is convenient for the nail gun body 2 to obtain the nails in the nail storage bin 4 and perform nailing operations. The gun nozzle 3 is located below the nail gun body 2 and is opposite to the nail pushing mold 5. The gun nozzle 3 plays a role in guiding nail output and accurately controlling the number of nails output, thereby ensuring that the nails can be accurately nailed into the target object.

[0024] A vertical nail storage space is provided inside the nail storage bin 4 for storing a large number of spare nails. A nail pushing cylinder 6 is installed at the bottom of the side of the storage bin. The nail pushing cylinder 6 is connected to the nail pushing mold 5. Front and rear limit sensors and a control solenoid valve are provided on the nail pushing cylinder 6. When working, the nail pushing cylinder 6 drives the nail pushing mold 5 to move, and pushes the nails in the storage bin to the nail gun in turn, realizing the automatic nail feeding function. The nail gun control air inlet 7 is arranged at the upper rear of the nail gun, and the compressed air inlet 8 is located on the side of the nail gun.

[0025] The nail gun body 2 is provided with an air storage chamber 1 105, an air storage chamber 2 107, an air storage chamber 3 104, an air storage chamber 4 106, a control valve core 101, a striker piston 102, a cylinder hole 108 and a cylinder hole 2 103 and other components. The control valve core 101 is located below the air storage chamber 2 107, and the striker piston 102 is slidably arranged inside the control valve core 101. The air storage chamber 1 105 is connected to the compressed air inlet 8. The air storage chamber 2 107 is located at the top of the nail gun body 2 and is connected to the nail gun control air inlet 7. The air storage chamber 3 104 is located above the control valve core 101 and is connected to the top of the control valve core 101 to push the striker piston 102 to move to drive out nails. Chamber four 106 is located on one side of the control valve core 101 and is connected to the bottom of the control valve core 101 to assist the resetting of the striker piston 102. The cylinder hole 108 is opened at the top of the air storage chamber four 106. The air storage chamber four 106 is connected to the air storage chamber three 104 through the cylinder hole 2 103. The air storage chamber one 105 continuously supplies compressed air through the working compressed air inlet 8. When the air storage chamber two 107 stops supplying compressed air through the nail gun controlling the air inlet 7, the control valve core 101 moves upward, and the compressed air enters the air storage chamber three 104, pushing the striker piston 102 to move downward quickly to drive the nail out. At the same time, compressed air is supplied to the air storage chamber four 106 through the cylinder hole 108. When the nail gun controls the air inlet 7 to deliver compressed air to the air storage chamber 2 107, the control valve core 101 moves downward, and the compressed air in the air storage chamber 4 106 enters the air storage chamber 3 104 through the cylinder hole 2 103, pushing the striker piston 102 upward to return to the initial position, completing a nailing cycle.

[0026] This device cooperates with an automatic control system such as a PLC, and utilizes the front and rear limit sensors of the nail pushing cylinder 6 to control the solenoid valve to realize the automatic nailing function, and adjusts the compressed air of the nail gun control air inlet 7 by controlling the solenoid valve, thereby accurately controlling the nailing frequency and action of the nail gun. The nailing speed of the nail gun device can be adjusted within the range of 1-15 times / second.
