Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the present invention is described in detail.
Embodiment 1
With reference to Fig. 1, Fig. 2, gap type fine cracking double roller machine is adjusted in a kind of spring pressurization swing arm, is made up of frame 1, fixed roll roller system 2, screeding device 3, action roller roller system 4, bearing pin 5, swing arm 6, mechanical stop limiter 7, spring buffer gap adjusting device 8, hood 9, Side baffle mechanism 10 and adjustment bolt group 11; Fixed roll roller system 2 is connected in frame 1 by its bearing block, and the swing arm 6 of action roller roller system 4 is connected in the internal pin bores of frame 1 by two bearing pins 5, and action roller roller system 4 can freely swing around bearing pin 5; Swing arm 6 other end by pin and spring buffer gap adjusting device 8 hinged, spring buffer gap adjusting device 8 to be connected on the supporting seat of frame 1 end by pin and can to freely swing; Mechanical stop limiter 7 is bolted in frame 1 both sides, and the ball top of mechanical stop limiter 7 is supported on the jacking block of swing arm 6; Two screeding devices 3 are connected in frame 1 by adjustment bolt 20; Hood 9 is bolted in frame 1; Side baffle mechanism 10 is connected to the inner both sides of hood 9 by adjustment bolt group 11.
With reference to Fig. 3, described spring buffer gap adjusting device 8 is made up of pinning 12, handwheel 13, bearing block 14, lead screw shaft 15, pressing plate 16, pull bar 17, spring 18 and silk braid 19; Lead screw shaft 15 is installed on bearing block 14 by bearing, and the screw thread of axle head is connected with silk braid 19, and spring 18 is compressed by pull bar 17 and pressing plate 16 by silk braid 19; Handwheel 13 is connected to lead screw shaft 15 axle head, handwheel 13 is equipped with pinning 12.
As shown in Figure 4, described screeding device 3 is by adjustment bolt 20, knife rest 21, and spring 22, cutter holder 23 and wing 24 are formed; Wing 24 is arranged in cutter holder 23 by bolt, and cutter holder 23 bottom is welded with 2 leads and 1 spring pull bar.2 leads are arranged in two pilot holes of knife rest 21, and the spring pull bar that spring 22 is arranged on cutter holder 23 is compressed by nut and knife rest 21; Knife rest 21 two ends have adjustment bolt 20 to be connected in frame 1 by whole screeding device 3.
Operation principle of the present invention is:
Drive motors selects two threephase asynchronouses (selecting degree of protection according to presence states), drives big belt pulley to drive action roller and fixed roll to rotate in opposite directions respectively by small belt pulley.In the course of the work, 2 motors are connected with the belt pulley of fixed roll roller system 2 with action roller roller system 4 respectively by belt.Tighten adjustment big nut in spring buffer gap adjusting device 8 to correct position, ensure that two springs 18 reach required decrement, obtain required precompression.The handwheel 13 of adjustment spring buffer gap adjusting device 8, makes the gap of action roller roll surface and fixed roll roll surface be 1mm.Adjust suitable after the pinning of two on handwheel 13 12 is tightened.Tighten the adjusting nut of mechanical stop limiter 7, the ball top of mechanical stop limiter 7 is posted by the swing arm of action roller roller system 4, prevent from shaking in the course of work roll surface that resilience causes and the abnormality such as to collide.Adjustment terminates rear energising and runs, and dallying can pan feeding after 5 minutes.Material is by the blanking of feeding mouth mean gravity, now the roll surface of action roller roller system 4 is subject to the extruding force of material, this power is applied to buffering gap adjusting device, spring is made to have a small amount of compression, in order to ensure roll gap, can suitably adjust handwheel 13 according to the numerical value of roll gap monitoring equipment reflection, make roll gap gap ensure at 1mm, ensure product grading.Pinning 12 and mechanical stop limiter is locked after smooth working.When the hard foreign matter of bulk appears in supplied materials, spring significantly compresses dodges, and power-off signal in when roll gap monitoring equipment monitors abnormal data, cuts off the electricity supply, prevent equipment from causing damage.Material, after fragmentation, is discharged by discharging opening, enters next process, and wherein the bearing block of action roller roller system and fixed roll roller system is all subdivision structure, removes and installs conveniently during overhaul, need not the online truning fixture of mounting structure complexity.
The spring 18 of described spring buffer gap adjusting device 8 provides pretightning force.The pretightning force provided due to leverage spring is comparatively large, when crushing force be applied to roll surface be passed to spring buffer gap adjusting device time, can manual a small amount of adjustment handwheel 13 according to the data of roll gap monitoring equipment reflection, ensure minimum roll gap.Significantly change when roll gap is at supplied materials, be illustrated as accident condition, buffer unit correspondingly significantly can compress to reduce the damage of foreign matter to roll surface and bearing.Adopt linear displacement transducer monitoring roll gap, setting roll gap power-off when 30mm, spring design is considered that roll gap enters still can to dodge when diameter is less than the foreign matter of 50mm and is passed through, and security is higher.
Screeding device 3 is installed on by adjustment bolt 20 and runs through in the square opening of machine frame inside, and adjustment bolt 20 adjustable blade sheet 24 is apart from the distance of roll surface, and screeding device inside is provided with buffer spring 22, flexiblely dodges characteristic; Screeding device can realize quick-detachment, changes the blade of wearing and tearing.
Sexual valence of the present invention is higher, clearance control accurately facilitates adjustable, precompression is large, security is higher, axle system adopts can subdivision external bearing block, and bearing is easy to sealing, and easy installation and removal, complete machine, also without the need to configuring online truning fixture, can work in bad working environments (open air as larger in the temperature difference and cold district); Energy consumption comparatively ordinary straight mode fine cracking double roller machine and fluid pressure type fine cracking double roller machine obviously reduces; Fully take into account the situation of abnormal charging; Twin rollers scraper plate easy to wear has elasticity and dodges characteristic, and changes rapidly, does not affect production; Roller system adopts Split type bearing support, easy accessibility.
