TW201930026A - Continuous nail feeding structure of pneumatic nail machine capable of continuously feeding nails to meet the requirement of massive application - Google Patents

Abstract

The present invention relates to a continuous nail feeding structure of pneumatic nail gun, which is mounted on a pneumatic nail gun and comprises an air flow guiding tube, an automatic restoration cylinder, and a pushing member. The air flow guiding tube enables the working air flow discharged by the pneumatic nail gun to flow into the automatic restoration cylinder for driving the piston rod of the automatic restoration cylinder to a retracted position. The piston rod is pushed by a restoration spring in the automatic restoration cylinder to go back to an extended position. The pushing member is fixed to the piston rod and has a pushing rod. The pushing rod is moved along with the piston rod for pushing the nail row of pneumatic nail gun forward. Thus, while injecting nails, the present invention utilizes the discharged working air flow for pushing the nail row forward, so the length of nail row is not limited and capable of feeding nails continuously, thereby meeting the requirement of massive application.

Pneumatic nailing machine

This creation is about the pneumatic nailing machine, especially the nail feeding structure of the pneumatic nailing machine.

Pneumatic tools, such as pneumatic nail guns, are tools that use the compressed air provided by the air compressor to drive the air motor and output the kinetic energy. It has fast motion, strong adaptability, and can be flammable, explosive, humid, and impactful. Work in harsh environments, no pollution to the environment, long working life, simple structure, easy maintenance.

The nail gun is a tool used in construction and decoration. The nail is used to connect different workpieces through a nail gun. A conventional nail gun, such as the "nail assembly and the nail gun including the nail assembly" of the Taiwan Patent Publication No. I603818, discloses a nail assembly and a nail gun including the same. The magazine assembly includes: a body and a nail rail assembly. The nail rail assembly is disposed on the base body and a nail unit moves against the first direction, and the nail gun comprises the above-mentioned nail assembly, and further comprises: a pressing member, a shell and a collision a casing, the casing is provided with a nail region for accommodating the nail assembly, the nail assembly and the casing defining a nail opening for the corresponding portion of the nail unit, the pressing member and the collision The plate is in a linked relationship. When the pressing member is moved to the housing by external operation, the collision plate is driven to move toward the opening of the nail opening, and the nail unit is fired and fired.

This conventional nail gun can only be installed with a fixed length of the nail unit. When the nail unit is used up, it needs to be refilled with a new nail unit, which is quite inconvenient and time consuming in mass use. .

The main purpose of this creation is to expose a continuous nail structure of a pneumatic nailing machine to meet the needs of a large number of uses.

In order to achieve the above object, the present invention provides a continuous nailing structure of a pneumatic nailing machine, which is mounted on a pneumatic nailing machine having a nail with a row of nails and a connecting nail and a nail head that receives the nail, an air inlet that is connected to a pneumatic source, a pressure member that opens the air source to provide a working airflow, and a vent hole that discharges the working airflow.

The nail feeding structure includes an air flow guiding tube, an automatic resetting cylinder and a pushing component, wherein the air guiding tube has a first end and a second end, the first end connecting the exhaust hole to receive The working airflow discharged by the venting hole, the automatic resetting cylinder is fixed on the pneumatic nailing machine, and has a cylinder tube, a piston rod and a return spring, the cylinder tube has an air flow inlet connecting the second end a venting outlet for discharging the working airflow, the piston rod is disposed in the cylinder tube and is moved to a retracted position by the working airflow from the venting hole, and is returned by the pressing of the returning spring In an extended position, the shifting member is fixed to the piston rod and has a shifting lever that moves the plunger to advance as the piston rod moves.

Accordingly, when the user presses the pressing member, the working airflow is generated, and the hammer is ejected by the punching force by the force of the working airflow, and the used working airflow is discharged through the exhaust hole. And being guided by the air guiding tube into the automatic resetting cylinder, thereby pushing the piston rod to a retracted position, and at this time, the piston rod is returned to the extended position by the return spring, and thus the shifting The rod can be advanced by the movement of the piston rod as it moves forward and backward.

The detailed description and technical content of this creation are as follows:

Please refer to FIG. 1 and FIG. 2 , which are schematic diagrams showing a first state of the exploded structure and a preferred embodiment of the present invention. As shown in the figure, the present invention is a continuous nail structure of a pneumatic nailing machine, which is mounted on a On the pneumatic nailing machine 10, the pneumatic nailing machine 10 has a magazine 11 with a row of nails 12, a nail head 13 connected to the magazine 11 and receiving the nail 12, and a connection pressure. The air inlet 14 of the source 20, the pressing member 15 that opens the air source 20 to provide a working airflow 21, and a venting opening 16 for discharging the working airflow 21.

The nail feeding structure includes an air flow guiding tube 30, an automatic resetting cylinder 40 and a pushing member 50, wherein the air guiding tube 30 has a first end 31 and a second end 32, and the first end 31 is coupled to the The venting opening 16 receives the working airflow 21 discharged from the venting opening 16 and the airflow guiding tube 30 can be formed using generally common high pressure resistant tubing, such as a fiberglass braided tube or the like.

Referring to FIG. 3 again, the automatic reset cylinder 40 is fixed to the pneumatic nailing machine 10 and has a cylinder tube 41, a piston rod 42 and a return spring 43 having a connection. The air inlet 411 of the second end 32 and a vent outlet 412 for discharging the working airflow 21, the piston rod 42 is disposed in the cylinder tube 41 and is moved to the air by the working airflow 21 from the venting opening 16 The retracted position (as shown in Fig. 2) is returned to an extended position by the pushing of the return spring 43 (Fig. 3). In a practical implementation, the piston rod 42 of the automatic reset cylinder 40 is disposed in the cylinder tube 41, and the cylinder tube 41 is separated from a spring region 413 and a plenum region 414, and the air inlet 411 is deflated. An outlet 412 is disposed on the plenum region 414, and the return spring 43 is compressedly received in the spring region 413 to urge the piston rod 42 toward the extended position, whereby the working airflow 21 enters the gas. In the chamber area 414, since the air outlet 412 cannot be vented immediately, the piston rod 42 is pushed to move to the retracted position (as shown in FIG. 2), and the return spring 43 is compressed, and when the air outlet 412 gradually When the working airflow 21 is vented, the return spring 43 will push the piston rod 42 back to the extended position by the elastic force (Fig. 3).
