Mainly there are following four defectives in this guide frame of paper cutter:
1. slide block slides in chute repeatedly, and contact-making surface weares and teares easily, and after the working time was long, wearing clearance increased, and this directly causes the angle between two slide blocks to change, thereby makes the height difference of cutter bed and arranged on left and right sides, and influence cuts precision; Simultaneously, machine also can bring very big noise and vibration because of the gap between slide block and the chute when operation, and particularly the cutter bed vibration when top dead centre and lower dead center conversion is more obvious.
2. when cut paper, hand papercutter can produce certain impulsive force, and eccentric shaft is subjected to this impulsive force, angular displacement takes place easily, also can make the left and right height difference of cutter bed, influence cuts precision, for this reason, need often to adjust the angle between two slide blocks, shortened the effective time.Simultaneously, impulsive force also may cause eccentric shaft distortion, makes the left and right Height Adjustment difficulty of cutter bed.
3. because the wearing and tearing between slide block and cutter bed chute are inevitable, in order to protect the cutter bed, so with slider designs is wear-out part, can change, but it is very loaded down with trivial details to change slide block, need stop machine run, take major and minor frame apart, take out the cutter bed with lifting device and change slide block on the mainframe, this not only influences ordinary production, and waste time and energy, very inconvenient; And tool setting bed material and chute machining accuracy and fineness require very high, otherwise can produce bigger frictional resistance, so material cost, processing cost are all high.
4. eccentric shaft pilot hole direct and on the cutter bed cooperates, because quality of fit is very high, is interference fits, adjusts eccentric angle and requires great effort very much, is difficult for harmonizing, and often needs repeatedly to adjust just to make the left and right height of cutter bed identical.
As everyone knows, the linear guides pair has splendid anti-wear performance, is used widely in engineering goods.But because this special construction of paper cutter bed guiding, and indissociable characteristic between secondary slide block of linear guides and the guide rail, cause it to assemble in paper cutter bed guiding and bring difficulty, the linear guides pair is not used on the world, domestic paper cutter bed guiding always at present.
