Reciprocating guide mechanism for needle loom

Abstract

It is about the reciprocating guiding mechanism of a needle machine. It comprises an oil cavity attached guide bushing base, upper and bottom guide bushings, propeller rod, upper and bottom sealing head, with No.1 and No.2 through holes connected with the oil cavity on both sides of the guide bushing base, the No.1 through hole connected with the lubricant source and the No.2 through hole with the tube channel. The upper and bottom guide bushings are located inside the upper and bottom end of the cavity of the guide bushing base with propeller rods inside them, the upper and bottom sealing head fastens to the upper and bottom end of the guide bushing base, featuring in the oil reservoir for lubricant sources, through fitting with the No.1 through hole. The said tube channel is used to as the exhaust for the air inside the oil cavity. It is simple in structure, simplifying the processing and installation of the upper and bottom sheath, reducing the possibility of leakage of lubricant, with natural lubricating effect.

Description

technical field [0001] The invention relates to a reciprocating guide mechanism of an acupuncture machine, which is used to realize a transitional transmission connection between the connecting rod of the acupuncture machine and the movable needle beam, so that the movable needle beam can reciprocate up and down, and belongs to the acupuncture machine field of application technology. Background technique [0002] As the reciprocating guide mechanism of the acupuncture machine, it is a mature technology on the acupuncture machine. It is composed of a guide sleeve seat, a pair of guide sleeves, a push rod, an upper and a lower sealing cover. The frame of the stab machine is fixed, a pair of guide sleeves (also known as copper sleeves) are respectively fixed on the upper and lower ends of the cavity of the guide sleeve seat, and the push rod is inserted into the pair of guide sleeves. The upper and lower ends are respectively connected with the connecting rod and the movable n...

Problems solved by technology

However, this structure is more suitable for high-speed needle looms, but not suitable for ordinary needle looms with low speed (about 600-700n / min).

One is to equip an ordinary acupuncture machine with a set of complicated but not simple structures consisting of an oil tank, a coarse filter, a gear pump, a motor, a fine filter, etc. 2) The lubricating oil source device will cause configuration waste, and the processing and installation of the lubricating oil source device are also relatively troublesome; the second is to deliberately process the upper and lower guide sleeves 2 and 3, for example, the upper and lower Oil grooves 21, 31 and grooves 22, 32 are respectively provided on the guide sleeves 2, 3, so the process is very cumbersome. The upper and lower ends of the cavity of the sleeve seat 1, so the assembly is difficult and the requirements are strict; the third is that opening too many through holes on the side of the guide sleeve seat 1 will increase the probability of lubricating oil leakage, for example, in addition to the necessary In addition to the first and second through holes 12 and 13 that pass through the cavity, through holes for screwing in positioning screws 23 and 33 need to be opened; the fourth is that the entire set of ordinary acupuncture machines will lose their due price advantage
