Description
Technical field
Utility model belongs to casting films production technical field, and being specifically related to one can tool changing device online.
Background technology
Cast film is when producing, and owing to receiving the existence of width, the thickness that result in casting films both sides is far longer than centre, can not come into operation, and thus needs casting films not care about one's appearance to be carried out as required excising as rim charge and recycling further.In prior art; the excision of casting films end limit is depended on to the cutting knife settled above end limit; but under long-term working order continuously, easily there is aging, blunt phenomenon in cutting knife, thus affects trimming effect; rupture of membranes phenomenon is even caused to occur; if and change, due to continuous prodution need, can only shut down completely; thus affect manufacturing schedule, thus need improvement badly.Chinese utility model patent CN 201783990 discloses a kind of hollow type can allowing blade replacement cutting knife online, which solve online tool changing and after avoiding film dividing, be again engaged two technical problems, but only with regard to online tool changing, its structure is comparatively complicated, need beyond knife rest, support, blade and screwing bolts, also must adjustment cushion block be additionally set, during adjustment, needs operating personnel to have wide experience, workman's technical capability be there are certain requirements.
Utility model content
The utility model object be to provide a kind of structure and operation is all better simply can tool changing device online, workman is not needed to have higher technical operation level, online tool changing can be carried out not affecting in production line progress situation, thus reduce because blade problem is for the impact of cast film line.
The utility model to solve the problems of the technologies described above the technical scheme of employing as follows:
One can tool changing device online, comprise fixed bar, sheath and blade, described sheath is the straight strip of both ends open and the quantity of described sheath has two at least, have at least in two described sheaths and be provided with blade, described blade is the strip matched with described sheath size, described sheath, blade and fixed bar all offer locating hole, screwing bolts passes through described locating hole by described sheath, blade is fixed on the same side of described fixed bar, each described blade have two locating holes at least and all locating holes are arranged in a row, the line at its center is parallel with the long limit of described blade.
The beneficial effects of the utility model are: two sheaths and two blades matched with it are fixed on the same side of fixed bar simultaneously, during use, one of them blade is fixed on fixed bar by one, its top locating hole together with sheath, sheath is stretched out in the bottom of this blade, just contact and cut casting films, namely it is in cutting operating position; Another blade is fixed on fixed bar by a locating hole of its underpart together with sheath, and the bottom of this blade does not contact with casting films, and namely it is not in cutting operating position; When needs tool changing, unclamp screwing bolts and this blade is fixed on fixed bar by one, top locating hole together with sheath, now two blades are in cutting operating position simultaneously, unclamp screwing bolts by needs more allowing blade replacement extract and change.Tool changing device structure of the present utility model and simple to operate, can realize online tool changing.
Further, the quantity of described sheath is two and side by side parallel is fixed on the side of described fixed bar.
Further, the both ends of each described blade are respectively provided with a locating hole.
Further, described blade and described sheath size match, the width of described blade and the width of described sheath opening little, its difference within 5mm, the thickness of described blade and the thickness of described sheath opening little, its difference is within 0.5mm.Adopt the beneficial effect of this further technical scheme to be control the size relation between blade and sheath, can ensure that blade position in sheath is relatively fixing, thus when ensureing its cutting casting films, cut line is straight.
Further, described blade is provided with multiple line of weakness, line of weakness or inclination certain angle parallel with the minor face of blade and crossing with long limit, blade both sides, blade can be fractureed along described line of weakness, described blade is divided into multistage by described line of weakness, the described blade between adjacent described line of weakness is provided with at least two described locating holes.The beneficial effect of this further technical scheme is adopted to be, when one end of blade cuts casting films is aging, blunt and when needing tool changing, the blade be arranged side by side with it is first set to operating position, then the blade that these needs are changed is taken off, only need the line of weakness be close to along its top to be fractureed by blunt for bottom blade, remaining blade again can be installed again and come into operation.
Further, one end of described blade is provided with safe handle of a knife.Adopt the beneficial effect of this further technical scheme to be arrange safe handle of a knife and can ensure to extract when tool changing not easily to hinder hand with during propulsion blade, security improves.
Further, described sheath is made up of rigid plastics or stainless steel, and described blade is made up of stainless steel.The beneficial effect of this further technical scheme is adopted to be use plastics or stainless steel material can ensure blade non-corrosive, have better useful life longevity.
