Description

Four-roller crusher roller gap self-checking device
Technical field
The invention belongs to crusher technical fields, specifically design a kind of four-roller crusher roller gap automatic adjustment dress It sets.
Background technique
Four-roller crusher is broken and fine crusher during one kind is structurally reasonable, compact, operating is reliable.Its working principle It is: material is brought by the frictional force of roller surfaces in the working chamber of two rollers, rolles over material with shearing force by squeezing It grinds and is crushed.The control of product granularity is to adjust system by hydraulic protecting the bearing block coupled with roll shaft is driven to move forward and backward, Then the gap between two rollers (drive roll and passive guide roller) is adjusted to realize.
The adjustment of present roller gap is that 2 front and back of driven voller bearing block is driven by the extension and retraction of the piston of oil cylinder 1 It moves and adjustment gasket 3 is used to adjust the position of bearing block, it is made to be positioned at the position of needs, to adjust between two rollers Gap.(each knob should be selected in manual before adjusting) its concrete operations are as follows: roller gap is adjusted, it can be by upper passive guide roller and lower quilt The oil cylinder separate regulation of dynamic roller, such as: first adjusting upper passive guide roller, be first shut off lower roll oil cylinder pipeline and accumulator control valve.Then Rigidity gasket needed for product granularity adjusts is added, and (referring to bearing block position scale, roller then starts oil to when zero for 115mm) Pump and roller forwarding button (1CT), oil pump push passive roll shaft to accumulator and upper roller oil cylinder back cavity fuel feeding, oil cylinder piston extension Seat Forward is held, when proceeding to bearing block and pushing down adjustment gasket, oil cylinder back cavity and accumulator oil pressure will rise, after reaching 5Mpa, It presses advance and stops button.At this moment bearing block position scale is observed, is then repeated if necessary to change gap with adjusting discharging-material size Movement is stated, increase and decrease adjusts gasket 3 to adjust it.It is above product granularity adjustment programme.It moves down roller adjusting method and moves up roller It is identical.But it may be noted that each control valve and control button corresponding operation after granularity has adjusted, are such as entered normal operating conditions Then the automatically controlled mode knob on electric cabinet should be threaded to automated location, such as start long-range control, then by the local/remote on electric cabinet Knob is threaded to remote location.When the supply of material, the adjusting shims of outfit are made of different-thickness, it should be noted that roller gap when adjustment It is subject to when adjusting gasket and being compressed by bearing block, increases and decreases gasket when necessary and adjust repeatedly several times.It is complicated to adjust program, adjust needs every time The time wanted is long, reduces production efficiency, increases production cost.And adjustment is manually carried out, the labor intensity of worker Greatly, the degree of automation is low.
Existing hydraulic control gap self-checking device includes hydraulic cylinder, accumulator and position sensor, position sensing Device is arranged on the piston rod of hydraulic cylinder, the pressure due to external impacts of the roller moment by material of crusher, in hydraulic cylinder The variation of power moment, is not able to maintain balance, cannot keep the position of sensor on piston rod.The oil pump of oil cylinder needs the moment to open It is dynamic, the position of sensor is kept by proportioning valve positive action, necessarily leads to the variation of roller gap in the course of work, is influenced The particle size after cracking of material reduces yield rate.
Summary of the invention
