A kind of vacuum system of packaging facilities
Technical field
The present invention relates to the packaging facilities field, more particularly, relate to a kind of vacuum system of packaging facilities.
Background technology
Vacuum system is as the vacuum section of many packaging facilities.Comprise vacuum pump, evacuated panel, guide rod, guide rod slideway, spring, vacuum chamber, sensor, cylinder and control system.The vacuum system of current packaging equipment is to pass the guide rod passage by guide rod, and an end is equipped with evacuated panel, and the other end is installed cylinder.Evacuated panel links to each other with vacuum pump by tracheae.The control of the controlled system of cylinder and vacuum pump.Vacuum chamber is installed on the body.When the packaging bag of filling blanking falls in the vacuum chamber, sensor imports the signal of sensing into control system, and the control system control cylinder promotes the guide rod motion.Guide rod drives the evacuated panel that is installed on the guide rod by the guide rod passage and seals the packaging bag sack.Control system control begins packaging bag is bled with evacuated panel bonded assembly vacuum pump.After the time that is provided with in control system arrived, control system control closing device sealed packaging bag.The control system control cylinder is released guide rod then, and the vacuum chamber base plate is opened at the control motor simultaneously, allows packaging bag skid off automatically.After skidding off Deng packaging bag, sensor imports signal into control module, and the vacuum chamber base plate is closed at the control module control motor.So circulation.Because of needs reach the packing effect, the positive empty time of taking out of individual packaging needs very long.It is longer to finish the time that the vacuum of whole packing needs, and causes other motions of machine all to be in wait state.Because of each parts of vacuum system install all very near, mutual influence is difficult to regulate, and brings great difficulty to maintenance.

Described telescopic packaging bag compression set 20 comprises evacuated panel 2, guide rod 3, guide rod passage 4, antifriction-bearing box 5, spring 10, described evacuated panel 2 is connected with guide rod 3 one ends, the other end of guide rod 3 is installed antifriction-bearing box 5, antifriction-bearing box 5 is fitted with the edge of cam 6, described guide rod 3 is sleeved on the guide rod passage 4, mounting spring 10 on the guide rod 3 between guide rod passage 4 and the antifriction-bearing box 5, and described packaging bag compression set 20 is fixing structure, packaging bag compression set 20 is set to four, and the angle between each packaging bag compression set 20 is 90 degree.
Described gear wheel shaft 8 is set to stand vertically the structure on vacuum system pedestal 19, and gear wheel shaft 8 is near an end and electrical motor 15 engagements of vacuum system pedestal 14, and the other end is captiveed joint with circular calibrated disc 9.
Described calibrated disc 9 is set to the rotating structure of horizontal arrangement, and four rotating vanes 11 are installed on the calibrated disc 9,90 degree of being separated by of the angle between every rotating vane 11, and rotating vane 11 front ends are connected with vacuum chamber 1, and the one side of vacuum chamber 1 close sensor 12 is provided with screw 18.
Described cam 6 is set to fixed structure, on cam 6 and the bracing frame 17 cooresponding positions recessed structure is set.
Described can with vacuum chamber inwall 21 that evacuated panel 2 contacts on the silica-gel sponge bar 22 of projection of the flexibility in a week is set, thereby make the structure that constitutes cavity when evacuated panel 2 contacts with vacuum chamber inwall 21.
Described sensor 8 is installed on the bracing frame 17, sensor 8 be set to vacuum chamber 1 on the cooresponding structure in screw 18 positions.
Described four evacuated panels 2 are connected by tracheae respectively with between the vacuum pump 14, and tracheae is communicated on the evacuated panel 2.
Principle of work of the present invention is:
When vacuum system of the present invention moved to position shown in Figure 2, antifriction-bearing box 5 was in the depression position of cam 6.The spring 10 that is enclosed within on the guide rod 3 is to be in extended state.The evacuated panel 2 that is installed in guide rod 3 heads and vacuum chamber 1 segment distance of being separated by.The packaging bag 13 that be equipped with blanking this moment falls in the vacuum chamber 1.PLC control module 16 control motors 15 driven gear axles 8 rotate.The calibrated disc 9 that is installed on the gear wheel shaft 8 moves simultaneously.This rotating vane 11 will enter the outshot of cam 6 this moment, and the packaging bag sack is pushed down in the guide rod reach.Spring between antifriction-bearing box and the guide rod passage is compressed.After sensing the screw 18 that is installed in next rotating vane 11 tops when sensor 12, import signal into PLC control module 16,16 control motors, 15 stop motions of PLC control module, the rotating vane 11 that enters cam 6 depression positions is because of action of the spring, promote to move behind the guide rod evacuated panel 2 that is installed in guide rod 3 heads and vacuum chamber 1 segment distance of being separated by.The packaging bag 13 that be equipped with blanking this moment falls in the vacuum chamber 1.Other three rotating vanes 11 then are in the protrusion position of cam 6 this moment, evacuated panel 2 is pressed on the vacuum chamber inwall 21, and the silica-gel sponge bar 22 by projection constitutes the structure of cavity when making that evacuated panel 2 contacts with vacuum chamber inwall 21, so just sealed the sack of packaging bag 13, just can vacuumize packaging bag 13 by tracheae with evacuated panel 2 bonded assembly vacuum pumps 1.
After this packaging bag 13 exhausts vacuum, PLC control module 16 outgoing signals are given electrical motor 15, thereby make next rotating vane 11 forward to finish the position of the impeller 11 that packaging bag 13 vacuumizes, at this moment, this impeller 11 repeats the work of last impeller 11, so repeatedly, can realize that then four impellers 11 constantly work.Like this, just improved the work efficiency of the packaging facilities that the present invention relates to greatly.
Four rotating vanes 11 on the vacuum system of the present invention be separated by respectively 90 the degree, be installed on the calibrated disc 9.Guide rod passage 4 is installed in the bottom surface of rotating vane 11, be inserted with guide rod 3 in the guide rod passage 4, guide rod 3 head ends are installed evacuated panel 2, tail end is installed antifriction-bearing box 5, be with spring 10 on the guide rod 3 between antifriction-bearing box 5 and the guide rod passage 4, protrude the position when rotating vane 11 is in cam 6, spring 10 is in compressive state, evacuated panel 2 is pressed on vacuum chamber 1 inwall, has pushed down the sack of packaging bag 13; When rotating vane 11 is in the depression position of cam 6, spring 10 flicks naturally, promotes guide rod 3 simultaneously and drives evacuated panels 2 and move, thereby make evacuated panel 2 and vacuum chamber 1 segment distance of being separated by, because the effect of spring 10, antifriction-bearing box 5 moves along the edge of cam 6 always.
Cam 6 is installed in the upper bottom surface of sleeve 7.Sleeve 7 is enclosed within gear wheel shaft 8 middle parts.
After installing, all parts are fixed on the support frame 17.
In conjunction with the accompanying drawings the present invention has been carried out exemplary description above; obviously the concrete realization of the present invention is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present invention and technical scheme to carry out; or design of the present invention and technical scheme are directly applied to other occasions without improving, all in protection scope of the present invention.
