Description

Steel material bundler thread eye reset mechanism

Affiliated technical field

The utility model belongs to the package packing machine field.Relate to steel material bundler thread eye reset mechanism.

Background technology

The wire drive feeder of steel material bundler is sent wire rod into associated mechanisms by silk guide passage, through reeling off raw silk from cocoons, cut operations such as silk, stubborn silk, finishes steel and ties up process again.Its silk guide passage is made of jointly the thread eye of stationary components and the thread eye of rotating part.When steel material bundler finish one tie up process after, therefore the dislocation of the hole on the stationary components and the hole on the rotating part must reorientate, and recovers the original silk guide passage of wire rod, just can carry out the next one and tie up process.Existing detent mechanism Mining limit switch, the dislocation of two holes takes place in the method for blocking the power input easily, causes industrial accident.

Summary of the invention

The utility model provides a kind of thread eye reset mechanism that is used for steel material bundler.The silk guide passage that it can make the thread eye by two parts constitute after misplacing through a working process, is reliably reorientated, and recovers original silk guide passage.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of thread eye reset mechanism that is used for steel material bundler, it is characterized in that, it comprises that a cover is by active semiaxis joint [1], passive semiaxis joint [2], and screw [3], spring [4], the coupler that pin [5] linkage unit is formed, the transmission main shaft [6] that the helix shoulder is arranged, its end links by key and passive semiaxis joint [2], the other end has the axial region of helix shoulder to be installed in the rolling bearing pedestal [7], cut silk dish [12] puts together on transmission main shaft [6] with screw this end end face, cut on the silk dish [12] thread eye is arranged, one cover rolling bearing pedestal [7], be equipped with by screw [8] on the seat, spring [9], the stop assembly that pin [10] is formed, thread plate [11] puts together on the end face of rolling bearing pedestal with screw, thread plate has thread eye on [11], and the thread eye of cutting silk dish [12] and thread plate [11] is formed the silk guide passage of wire rod jointly.

The utility model has the advantages that accurate positioning is reliable, simple and practical.

Fig. 2 is the A-A section of Fig. 1.

Fig. 3 is the circumferential oblique single face shoulder scheme drawing of passive semiaxis joint flange end face.

Below in conjunction with accompanying drawing the utility model is described further.

1. semiaxis joints initiatively among the figure, 2. passive semiaxis joint, 3. screw, 4. spring, 5. pin, 6. transmission main shaft, 7. rolling bearing pedestal, 8. screw, 9. spring, 10. pin, 11. thread plates, 12. cut the silk dish.

The specific embodiment

In the embodiment shown in fig. 1, initiatively semiaxis joint [1] links with key and prime mover shaft, and passive semiaxis joint [2] links with an end of key and transmission main shaft [6].Initiatively axially all be afraid of two tapped bore on the flange of semiaxis joint [1], the linkage unit of being made up of screw [3], coil spring [4], pin [5] is housed on it, circumferentially all be afraid of two sections oblique single face shoulders on the flange end face of passive semiaxis joint [2], Fig. 3 is that one section oblique single face shoulder launches scheme drawing, initiatively the heart portion of semiaxis joint [1] has one female mouthful, there is a sub-platform in the heart portion of passive semiaxis joint [2], and two semiaxis joints are sleeved on together by female mouth and sub-platform, can slide relative.One helix shoulder is arranged on the transmission main shaft [6], Fig. 2 is the installation embodiment of itself and screw [8], spring [9], pin [10], this shoulder portion is loaded in the rolling bearing pedestal [7], be positioned at two cover bearing middle parts, this end end face of transmission main shaft [6] with screw with cut silk dish [12] and link, rolling bearing pedestal has a radial screw bore on [7], the stop assembly of being made up of screw [8], spring [9], pin [10] is housed on it, the end face of rolling bearing pedestal [7] links with screw and thread plate [11], and bearing seat and fixed frame link.

The working process of steel material bundler thread eye reset mechanism is as follows: be loaded on the pin [5] on the active semiaxis joint [1], under the effect of screw [3] and spring [4], press closer flange end face at passive semiaxis joint [2], when active semiaxis joint is just changeing, pin [5] acts on the oblique single face shoulder of passive semiaxis joint [2] flange end face shoulder, the transmission main shaft [6] that drives passive semiaxis joint [2] and link is with it cut silk dish [12] and is rotated together, pin this moment [10] surmounts the helix shoulder on the main shaft [6], finish and cut silk, when active semiaxis joint [1] counter-rotating, rely on the friction force between pin [5] and passive semiaxis joint [2] flange end face, the transmission main shaft [6] that drives passive semiaxis joint [2] and link is with it cut silk dish [12] and is rotated together, transmission main shaft [6] is in rotation, when its helix shoulder bumps against the pin [10] that is loaded on the rolling bearing pedestal [7], transmission main shaft [6] and the silk dish [12] of cutting that links with it stop operating, realization thread eye location, pin this moment [5] surmount the oblique shoulder shoulder of passive semiaxis joint [2] flange end face.
