Pneumatic gun nail-shooting pipeline and pneumatic nail-shooting gun

Abstract

The invention provides a pneumatic gun nail-shooting pipeline, comprising a first nail shooting plate, a second nail shooting plate and movable limiting assemblies, wherein the surface on one side of a first support frame is provided with a nail shooting slot along the axial direction, and the nail shooting slot is in counterpoint fit with an impact column of a pneumatic gun; the second nail shooting plate is oppositely jointed with the first nail shooting plate, a containing slot is arranged on the second nail shooting plate, and a conveying channel which is in counterpoint communication with the nail shooting slot is arranged at the center of the containing slot along the axial direction; the movable limiting assemblies are arranged in the containing slot and are symmetrically arranged on the two sides of the conveying channel, the movable limiting assembly arranged on each side of the conveying channel comprises a spring tongue, a torsion spring and a pivot shaft, the spring tongue and the torsion spring are connected into the containing slot by virtue of the pivot shaft which is penetratively arranged along the transverse direction, and the spring tongue and the torsion spring can rotate around the pivot shaft; and the torsion spring drives the spring tongue to return. According to the invention, the technical purpose of a pneumatic nail-shooting gun that a shooting structure has strong rigidity, the volume is large, and a nail with a thick cap is not easy to fracture can be achieved, and thus quality of finished shoes is improved; and the pneumatic gun nail-shooting pipeline disclosed by the invention has the advantages of long service life and high nail shooting accuracy.

Description

technical field [0001] The invention relates to the field of shoemaking, in particular to a nail-shooting pipe for a steam pressure gun and a nail-shooting gun with the same. Background technique [0002] In the field of shoemaking, the upper and inner sole are combined according to the shape of the shoe last to ensure that the finished shoe is shaped. At present, when assembling, a steam pressure gun is used to shoot out spikes to realize connection and fixation. But existing general steam pressure gun nail is non-professional shoe-making nail, and the shape of general steam pressure gun nail is similar to staple, and the two ends of nail body are the bending end that is right angle, when using, in steam pressure gun Under the impact of the impact column, the general-purpose steam pressure gun nails are driven into the joint by the steam pressure gun nailing pipe to realize the connection combination. After use, all must be removed to ensure that the user's feet are not hu...

AI Technical Summary

Problems solved by technology

[0003] 1. The nailing pipe of the existing steam pressure gun can only be used in conjunction with the general steam pressure gun nail, and the general steam pressure gun nail is easy to bend and break due to poor rigidity, and the nail head cannot be removed after the nail is broken. It is easy to scratch the user's feet, which will bring unnecessary losses and troubles to the manufacturer

[0004] 2. Due to the limitations of the impact column of the steam pressure gun and the structure of the nailing pipeline, the size of the general steam pressure gun nail is small, the pressure area of ​​a single steam pressure gun nail is small, and the number of nails that need to be nailed in the production process is large , it is easy to miss and pull out during the cleaning process

Moreover, the general-purpose steam pressure gun nails are light in weight and are easy to fall into the shoe clips. After the shoe is finished, it cannot be taken out, which affects the quality of the finished shoe.
