Abstract
The utility model discloses an automatic tension device of scraper chains of a plate dryer. The device comprises a compression nut (1), a spring pressed cover (2), a spring (3), a spring seat (4) and a screw (5). The spring pressed cover (2) and the spring seat (4) are respectively installed at two ends of the screw (5); the spring (3) is sleeved outside the screw (5); the spring (3) is positioned between the spring pressed cover (2) and the spring seat (4); the compression nut (1) is installed at one end of the screw (5); and the compression nut (1) is positioned on the outer side of the spring pressed cover (2). The device drives the screw to generate tension by adopting the counterforce generated by the spring which is pressed, to automatically adjust the tension degree of the scraper chain, changes the hard tension of the thrust force of a bolt into the automatic tension of the stretching force of the spring, ensures the scraper chain is always in proper tension state, and can enable a left chain and a right chain to be automatically in a synchronous state to guarantee the normal operation, thereby achieving zero fault during unmanned operation.
Description
Technical field
The utility model relates to automatic tension device, is specifically related to a kind of plate dryer flight chain automatic tension device.
Background technology
At present, the employed dull and stereotyped oven dry of vegetable oil mill: area 50mm
2～300mm
2, scraper plate width 1800mm～3000mm, scraper plate length 6000mm～10000mm.The rigid tensioner that the tail wheel of flight chain generally adopts bolt to promote, and require two chains if tensioner is untimely, then can cause the chain scraper large tracts of land to break, be out of shape, twine synchronously causes stopping production until scrapping, and is direct and indirect economic loss is huge; Existing swelling device can not be regulated chain length by automatic tension, need artificial running check chain degree of tightness situation, artificial tensioner, time-consuming bothersome, may cause left and right two chain tensioner degree varies to cause, the not timely tensioner of the chain that freely extends if be in operation can cause climbs chain, causes the scraper plate scraping article to break distortion when serious, produces trouble of shutdown.
Summary of the invention
The purpose of this utility model is: a kind of plate dryer flight chain automatic tension device is provided, and this device need not labor management when equipment moves, and can regulate the flight chain pitch automatically, keeps appropriateness to tighten up.
The technical scheme that its technical problem that solves the utility model adopts is: this swelling device comprises clamp nut, spring capping, spring, spring base and screw rod, at the two ends of screw rod difference mounting spring gland and spring base, outer casing spring on the screw rod, spring is between spring capping and spring base, on an end of screw rod clamp nut is installed, clamp nut is positioned at the outside of spring capping.
In a kind of plate dryer flight chain automatic tension device of the present utility model, spring base is installed on the dryer column, the other end coupling spindle bearing of screw rod.
In a kind of plate dryer flight chain automatic tension device of the present utility model, installation shaft bearing slide rail on the dryer column, bearing block is installed on the bearing block slide rail, and tailing axle is installed in the bearing block by bearing, establishes the bearing block bonnet on the bearing block.
During installation, screw clamp nut in advance to the degree of tightness appropriateness, clamp nut passes to spring capping with power, by spring capping power is passed to spring, by spring power is passed to screw rod to bearing block again; During work, freely extend, produce reaction force by spring and promote spring capping, thereby promote clamp nut, drive screw rod and make bearing block move free adjustment left if chain is in operation.
The utility model utilizes the spring pressurized to produce reaction force drive screw rod generation pulling force and regulates flight chain tensioner degree automatically, become the rigid tensioner of bolt thrust and be the flexible automatic tension of spring tension, make flight chain be in appropriate tensioning state all the time, and two chains are in synchronous regime automatically about making, guarantee normal operation, thereby reach unattended, operation zero failure.
