Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail.
With reference to Fig. 1, Fig. 2, a kind of gap formula fine cracking double roller machine of adjusting, by frame 1, fixed roll roller be 2, screeding device 3, action roller roller are 4, bearing pin 5, swing arm 6, mechanical stop limiter 7, spring buffer gap adjusting device 8, hood 9, side shield mechanism 10 and adjust bolt group 11 and form; Fixed roll roller is 2 to be connected in frame 1 by its bearing block, and action roller roller is that 4 swing arm 6 is connected to by two bearing pins 5 in the inside pin-and-hole of frame 1, and action roller roller is 4 can freely swing around bearing pin 5; Swing arm 6 other ends are hinged by pin and spring buffer gap adjusting device 8, and spring buffer gap adjusting device 8 is connected on the supporting seat of frame 1 end and can freely swings by pin; 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 adjusting bolt 20; Hood 9 is bolted in frame 1; Side shield mechanism 10 is connected to the inner both sides of hood 9 by adjusting 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 silk braid 19 compresses spring 18 by pull bar 17 and pressing plate 16; Handwheel 13 is connected in lead screw shaft 15 axle heads, and pinning 12 is housed on handwheel 13.
As shown in Figure 4, described screeding device 3 is by adjusting bolt 20, knife rest 21, and spring 22, cutter holder 23 and wing 24 form; Wing 24 is arranged in cutter holder 23 by bolt, and cutter holder 23 bottoms are welded with 2 leads and 1 spring pull bar.2 leads are arranged in two pilot holes of knife rest 21, and spring 22 is arranged on the spring pull bar of cutter holder 23 and is compressed by nut and knife rest 21; Knife rest 21 two ends have the bolt 20 of adjustment that whole screeding device 3 is connected in frame 1.
Operation principle of the present utility model is:
Drive motors is selected 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 4 to be 2 with fixed roll roller belt pulley is connected by belt and action roller roller respectively.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 adjusting spring buffer gap adjusting device 8, the gap that makes action roller roll surface and fixed roll roll surface is 1mm.Adjust after suitable two pinnings 12 on handwheel 13 are tightened.Tighten the adjusting nut of mechanical stop limiter 7, making the ball top of mechanical stop limiter 7 be posted by action roller roller is in 4 swing arm, the abnormality such as prevent from shaking in the course of work that roll surface that resilience causes is collided.Adjustment finishes rear energising operation, and dallying can pan feeding after 5 minutes.Material is by the even gravity blanking of feeding mouth, now action roller roller is the extruding force that 4 roll surface is subject to material, this power is applied to buffering gap adjusting device, make spring 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, roll gap gap is ensured at 1mm, ensure product grading.After smooth working, lock pinning 12 and mechanical stop limiter.In the time that the hard foreign matter of bulk appears in supplied materials, spring significantly compresses and dodges, when roll gap monitoring equipment monitors abnormal data in power-off signal, cut off the electricity supply, the equipment of preventing causes 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 convenience when overhaul, online truning fixture that need not mounting structure complexity.
The spring 18 of described spring buffer gap adjusting device 8 provides pretightning force.The pretightning force providing due to leverage spring is larger, in the time that crushing force is applied to roll surface and is passed to spring buffer gap adjusting device, according to manually a small amount of handwheel 13 of adjusting of the data of roll gap monitoring equipment reflection, ensures minimum roll gap.When roll gap significantly changes during at supplied materials, be illustrated as accident condition, buffer unit can correspondingly significantly compress to reduce the damage of foreign matter to roll surface and bearing.Adopt linear displacement transducer monitoring roll gap, set roll gap power-off in the time of 30mm, spring design considers that roll gap enters when diameter is less than the foreign matter of 50mm and still can dodge and pass through, and security is higher.
Screeding device 3 is installed in the square opening that runs through frame inside by adjusting bolt 20, adjusts the distance of the adjustable wing 24 of bolt 20 apart from roll surface, and screeding device inside is provided with buffer spring 22, the flexible characteristic of dodging; Screeding device can be realized quick-detachment, changes the sword sheet of wearing and tearing.
The utility model cost performance 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 online truning fixture of configuration, can be worked in bad working environments (open air and cold district as larger in the temperature difference); Energy consumption obviously reduces compared with ordinary straight mode fine cracking double roller machine and fluid pressure type twin rollers in small, broken bits; 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.
