Automatic stop device for feeding frame of flax gilling machine and working method thereof
Technical Field
The invention relates to a device and a method, in particular to an automatic stop device of a feeding frame of a flax gilling machine and a working method thereof, belonging to the field of flax gilling machines.
Background
The original feeding frame of the gilling machine automatically stops feeding strips, and the feeding frame is contacted with a lower roller through an upper roller, so that a PLC has an input signal and the machine stops; in the use process of the mechanical conduction circuit, a mechanical transmission part is rusted, the transmission rod is not well contacted, so that the PLC cannot accurately receive signals, the automatic stop is frequently out of order, the strips are uneven, and the product quality is influenced. Because the automatic stop is a series circuit, if one automatic stop is broken, other automatic stop lines need to be disassembled to accurately find a fault point, and the maintenance is troublesome.
The chinese patent publication No. CN211921793U, 11/13/2020, discloses a new utility model named "a drafting sliver-breaking automatic stop device for gilling machine". This patent sliver passes through the gill box in proper order, the draft roller, the draft leather roller, get into the horn mouth behind the compression roller, normal during operation, the sliver is pressed in the intraoral sliver backup pad of horn, the spring of sliver backup pad below is in compression state, the lug of sliver backup pad below with touch the button and be in contact state, when the sliver takes place disconnected strip, the sliver just can not be pressed in the intraoral sliver backup pad of horn, the spring that compresses resets, thereby drive the lug upward movement and with touch the button and break away from the contact, touch the button at this moment and give the controller with signal transmission, the controller gives the gill box with signal transmission again, inform the gill box parking. Although the automatic stop motion device for drafting broken sliver of the carding machine can automatically detect broken sliver and stop the gilling machine, and reduces the labor intensity of workers, the automatic stop motion device has poor automatic stop effect and cannot accurately receive signals, so the automatic stop motion device also has the defects.
Therefore, the automatic stop device for the feeding frame of the flax gilling machine, which has simple and reasonable structural design, can accurately find out the fault position in time and process in time, is especially necessary.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provides the automatic stop device of the feeding frame of the flax gilling machine and the working method thereof, which have the advantages of simple and reasonable structural design, safety, reliability, accurate fault position finding, timely maintenance and treatment and convenient operation.
The technical scheme adopted by the invention for solving the problems is as follows: this sub-ramie gilling machine feeding frame stop motion, including supporting panel, many guide rollers, a plurality of bottom rollers, a plurality of guide circle and a plurality of top roller, set up many guide rollers on the supporting panel, a plurality of bottom rollers and a plurality of top roller match each other, and a plurality of guide circles set up respectively in the bottom roller below that corresponds, its characterized in that: the automatic stop mechanism comprises a plurality of photoelectric sensing supports, a plurality of photoelectric switches I and a plurality of photoelectric switches II, wherein the photoelectric sensing supports are fixed on the supporting panel at intervals, the photoelectric switches I are respectively arranged at the corresponding upper rollers, and the photoelectric switches II are respectively arranged at the corresponding strip inlet outlets; the first photoelectric switch and the second photoelectric switch both adopt diffuse reflection photoelectric switches.
Preferably, the automatic stop mechanism further comprises a nut and a washer, and the photoelectric sensing bracket is mounted on the support panel through the nut and the washer.
The invention also provides a flax gilling machine feeding frame automatic stop device and a working method thereof, which are characterized in that: the method comprises the following specific steps:
(S1) adding a photoelectric switch II at the strip inlet of each feeding frame, stopping the machine after delaying for several seconds after the strip is broken, simultaneously feeding back a strip breaking signal to the touch screen, and enabling a vehicle stop worker to see screen information to know the accurate position of the broken strip and process the broken strip in time;
(S2) installing an automatic stop mechanism on the upper roller, and winding hemp strips on the upper roller due to humidity or unsmooth upper roller, and if the upper roller is seriously stuck;
(S3) installing a photoelectric switch I on the upper roller, winding the ramie stripes on the upper roller, automatically stopping the machine, feeding back the touch screen in time, and enabling a vehicle stop worker or a maintenance worker to accurately find out the fault position in time and process the fault position in time.
Compared with the prior art, the invention has the following advantages and effects: overall structure simple in design is reasonable, safe and reliable, through photoelectric switch one, photoelectric switch two in the self-stop mechanism, the fault location can in time be found to the accurate ability of car stop man or maintainer to in time handle, convenient operation, work efficiency is high, satisfies the user demand of production line.
