Abstract
The utility model discloses an automatic position limitation hydraulic baling press, wherein manual control mechanical commutation of the existing hydraulic baling press is changed to electric-control solenoid directional control valve (11), and the former pressure adjusting valve is changed to an electromagnetic relief valve (10); moreover, a travel limit switch (21) and a bumper (22) capable of switching off the circuit of the solenoid directional control valve (11) and the electromagnetic relief valve (10) are arranged within the travel of a guide bar (8) so as to make a hydraulic rod (6) stop working at the preset position. The utility model can realize automatic and accurate control of the travel of the hydraulic rod (6) to obtain uniform packed package according to the requirements of different packed articles on package specification.
Description
The utility model relates to a kind of hydraulic press-packing, and special and a kind of hydraulic press-packing that can the automatic accurate modulated pressure throw of lever is relevant.
Hydraulic press-packing is industries such as tobacco, cotton, fiber crops a kind of baling equipments commonly used.Existing hydraulic press-packing comprises that mainly framework, oil cylinder, fuel tank and hydraulic pressure connect control part.Hydraulic press-packing as the production of Xuchang, Henan Province Central Plains machine works.The lifting of this hydraulic press-packing modulated pressure bar is the mechanical commutation valve by a control oil channel, by the different gear control oil channel of operation reversing handle, thereby realizes lifting and stops.This hydraulic press-packing is in when packing, and the judgement that packaged thing is compressed degree is sensation and the experience with operating personal, when thinking fit, promptly operates reversing handle and stops to press down.Cause packaged thing inclusion not of uniform size easily like this, pressure is excessive even can cause packaged thing damage.For example when carrying out the tobacco leaf packing,, can make tobacco leaf extrude oil content, reduce quality of tobacco if pressure is excessive.
The purpose of this utility model be to provide a kind of can be according to the inclusion specification requirement of packaged thing, the automatic spacing hydraulic press-packing of the automatic accurate modulated pressure throw of lever.
Technical solution of the present utility model is such, change the mechanical commutation valve of existing hydraulic press-packing into solenoid directional control valve, adopt the electromagnetic relief valve pressure regulation, be equipped with operation control switch and stroke limit cut-out switch, come the commutation and the stroke of modulated pressure bar by control solenoid directional control valve and electromagnetic relief valve circuit.
This hydraulic press-packing is owing to adopt electromagnetic switch and circuit control, and is furnished with lead limit switch, can be automatically, the modulated pressure throw of lever exactly, can make the inclusion uniformity according to the requirement of the packaged thing inclusion of difference specification.
Below in conjunction with accompanying drawing the utility model is further elaborated.
