Summary of the invention
For the problems referred to above, the invention provides the safety feeding device of plastic film bag making machine, it can guarantee that in making bag by plastic film process, feeding roller easily crushes the problem that operating personnel point, and guarantees personnel's safety in production.
Its technical scheme is such, it comprises feeding drive roll and the feeding driven roll of parallel installation, the two ends of described feeding drive roll are installed on two side stands by bearing, and an end of its rotating shaft is in transmission connection by belt and belt pulley and direct current generator output, it is characterized in that: on described two side stands, be separately installed with slide block, described slide block is all fixed on by bearing in the two ends of described feeding driven roll, the front end of described feeding driven roll is provided with and approaches safety device, the described safety device that approaches comprises depression bar and approach switch, described slide block is fixed at described depression bar two ends, and parallel with described feeding driven roll, described approach switch is installed on support, the front end of described depression bar, described approach switch and described direct current generator electricly connect.
It is further characterized in that: the circuit that electricly connects of described approach switch and described direct current generator comprises approach switch circuit parallel with one another, signal relay circuit and direct current generator circuit, after described approach switch circuit, signal relay circuit and the parallel connection of direct current generator circuit, connect with inductance L, and then be parallel to the output of bridge full wave rectifier, the external 220V alternating current of described bridge full wave rectifier input with capacitor C; Described approach switch circuit comprises described approach switch and the resistance R 1 of mutual series connection, described signal relay circuit comprises described signal relay KS, resistance R 2 and the approach switch NO of order serial connection, and described direct current generator circuit comprises the described direct current generator M of mutual serial connection and the NC contact of described signal relay KS;
On described slide block, by spring, be also connected and installed with pressure adjusting lever.
Adopt the safety feeding device of plastic film bag making machine of the present invention, its beneficial effect is: its feeding driven roll and depression bar are all installed on two side stands by slide block, depression bar installed in front has approach switch, approach switch and direct current generator electricly connect, when the distance between feeding drive roll and feeding driven roll surpasses setting safety value, thereby the reach of feeding driven roll promotes slide block and depression bar reach, depression bar is near approach switch, approach switch is controlled direct current generator power-off and is shut down, thereby assurance operator safety, it is simple in structure, safe and reliable, can effectively guarantee personnel's handling safety, spring and pressure adjusting lever can effectively be adjusted the gap between feeding drive roll and feeding driven roll.
Accompanying drawing explanation
Fig. 1 is the safety feeding device structural representation of plastic film bag making machine of the present invention;
Fig. 2 is that structure for amplifying schematic diagram is looked on a left side of Fig. 1;
Fig. 3 be in the present invention approach switch and direct current generator electricly connect schematic diagram.
The specific embodiment
See Fig. 1 and Fig. 2, apparatus of the present invention comprise the feeding drive roll 9 and feeding driven roll 10 of parallel installation, the two ends of feeding drive roll 9 are installed on two side stands by bearing 4, and an end of its rotating shaft is in transmission connection with direct current generator 1 output by belt 3 and belt pulley 2, on two side stands, be separately installed with slide block 6, slide block 6 is all fixed on by bearing 4 in the two ends of feeding driven roll 10, the front end of feeding driven roll 10 is provided with and approaches erecting device, approach safety device and comprise depression bar 11 and approach switch 12, slide block 6 is fixed at depression bar 11 two ends, and parallel with feeding driven roll 10, approach switch 12 is installed on support, the front end of depression bar 11, approach switch 12 electricly connects with direct current generator 1.On slide block 6, by spring 7, be also connected and installed with pressure adjusting lever 8, by pressure adjusting lever 8 and spring 7, can promote slide block 6 and move forward and backward, thereby regulate the distance between feeding drive roll 9 and feeding driven roll 10.See Fig. 3, approach switch 12 comprises approach switch circuit parallel with one another, signal relay circuit and direct current generator circuit with the circuit that electricly connects of direct current generator 1, after described approach switch circuit, signal relay circuit and the parallel connection of direct current generator circuit, connect with inductance L, and then be parallel to the output of bridge full wave rectifier, the external 220V alternating current of bridge full wave rectifier input with capacitor C; Approach switch circuit comprises the approach switch 12 and resistance R 1 of mutual series connection, signal relay circuit comprises described signal relay KS, resistance R 2 and the approach switch NO of order serial connection, and direct current generator circuit comprises the described direct current generator M of mutual serial connection and the NC contact of described signal relay KS.
Specifically describe the course of work of the present invention below: operating personnel send into plastic sheeting between feeding drive roll and feeding driven roll, when finger is sandwiched between feeding drive roll and feeding driven roll, its clearance distance has between the two exceeded default safe distance, thereby the reach of feeding driven roll promotes slide block and depression bar reach, 220V direct current is through bridge full wave rectifier rectification, again through capacitor C, after inductance L filtering, make 220V direct current change 220V alternating current into, 220V alternating current is given approach switch through resistance R 1, and give signal relay KS through resistance R 1, when depression bar during near approach switch approach switch NO closed, signal relay KS adhesive, the contact NC of synchronous signal relay K S disconnects, direct current generator stops operating, thereby protection personnel's safety.
