Improved full-automatic threading apparatus

Abstract

The invention discloses an improved full-automatic threading apparatus, comprising an air feeding mechanism, a lead tube, a take-up and pay-off mechanism, a guide line, a bullet, a motor, a limiting shutdown assembly, and a control system, wherein the air feeding mechanism is externally connected with an air compressor and transmits power to threading; the lead tube is arranged inside the air feeding mechanism; the take-up and pay-off mechanism corresponds to the position of the rear end of the lead tube; one end of the guide line is fixed and wound on the take-up and pay-off mechanism and the other end penetrates to an air outlet of the air feeding mechanism through the lead tube; the bullet is connected to one end of the guide line penetrating out of the lead tube; the motor provides take-up and pay-off power; the limiting shutdown assembly is arranged at the front part of the air feeding mechanism and connected with the front part of the lead tube. The previous generation of equipment is modified and innovated, the functions of paying off and taking up a clutch structure, wireless remote control and the like are added, the improved full-automatic threading apparatus is more reasonable to use, simpler and more convenient to control, the motive power mode, the original limit mechanism and the structure of the original wire-draw plate are also optimized, an excellent limiting shutdown function and the functions of fairing lines, arranging lines and paying off and taking up lines are achieved, and winding and knotting of the guide line in the take-up and pay-off processes are effectively prevented.

Description

technical field [0001] The invention relates to a threading device, in particular to an improved automatic threader. Background technique [0002] Indoor circuit threading is a basic work that must be carried out after building construction or decoration, whether it is a bungalow, a building, or a factory building. First of all, the safety of the circuit should be put first, so as to ensure that the use of electrical appliances in the future will not cause personal electric shock and electrical fire accidents. [0003] The existing indoor threading work is usually done manually. The process is: first install a PVC flame-retardant threading pipe underground, and then the staff penetrates the steel wire from one side of the wall, and the steel wire passes through the PVC flame-retardant threading pipe to the other. One side of the wall, and then dock with the wires on the other side of the wall. After the docking is completed, the steel wire is pulled back so that the wire is...

AI Technical Summary

Problems solved by technology

[0004] (1) Since the flame-retardant threading pipe is relatively long, and the wire groove turns too much, it is difficult for the steel wire to pass through the threading pipe, and it is easy for the steel wire to get stuck in the flame-retardant pipe during the threading process. When hooking, the staff must go to the edge of the wall on the other side and use other steel wires to hook.

[0005] (2) Since the construction line pipe is only 4 meters long, it is necessary to connect the line pipe during construction. When the steel wire passes through the joint of the two line pipes, it is easy to be blocked. At this time, it needs to be manually unhooked. When the steel wire passes through the other end smoothly and connects with the wire at the other end, the wire must first be straightened manually. If it is not straightened, the wire will be subjected to great resistance in the wire tube during the pulling process. , seriously hampered the pulling work

[0006] It can be seen from the above that the traditional threading method is cumbersome and requires a high degree of labor, and the entire construction progress is very slow. Not only is the threading speed slow, labor-intensive and time-consuming, but the construction cost is not low

The problems of cumbersome work process and heavy workload have seriously hindered the development of the industry

[0007] The inventor has invented and created a threader for the defects of the prior art. The Chinese patent number is ZL201220547535.7, which solves related problems to a certain extent, but also encounters some other problems during use, such as pulling back It is impossible to accurately grasp whether the wire has been pulled back in place, and it is not reasonable enough to control its stop, which is inconvenient for its normal use.
