The improved capper of a kind of hot pressing bar mounting groove
Technical field
The present invention relates to a kind of capper, the improved capper of especially a kind of hot pressing bar mounting groove
.
Background technology
Existing capper comprises capper body and is installed in the hot pressing bar mounting groove of capper body, in this hot pressing bar mounting groove, be equiped with resistant to elevated temperatures hot pressing bar, position corresponding with this hot pressing bar on capper body is provided with heating platen, and hot pressing bar matches with heating platen the oral area Heat Sealing of sack.The degree of depth of existing capper hot pressing bar mounting groove is fixing nonadjustable, after hot pressing bar period of service is permanent, can be difficult to clamp between hot pressing bar and heating platen, and causing can not be by the oral area Heat Sealing of sack.In addition, because the degree of depth of hot pressing bar mounting groove is fixing nonadjustable, the processing of hot pressing bar will strictly coordinate the degree of depth of hot pressing bar mounting groove, but the working accuracy of hot pressing bar is difficult to strict control, causes the reject rate of hot pressing bar high.。
Summary of the invention
The object of the invention is to provide the improved capper of a kind of hot pressing bar mounting groove, to overcome fixing can not the adjustment of the degree of depth of hot pressing bar mounting groove in prior art, is difficult to clamp the high problem of reject rate of hot pressing bar between hot pressing bar and heating platen.
The present invention adopts following technical scheme:
The improved capper of a kind of hot pressing bar mounting groove, comprise capper body and the hot pressing bar mounting groove that is installed in capper body, in this hot pressing bar mounting groove, be equiped with hot pressing bar, this hot pressing bar mounting groove is equiped with the lifting mechanism that can control this hot pressing bar mounting groove bottom oscilaltion.
Above-mentioned lifting mechanism comprise be fixed at described hot pressing bar mounting groove bottom at least one nut and with described nut suitable take the lead screw rod, this is taken the lead the activity of screw rod one end and is assemblied in this nut, the described screw rod other end of taking the lead runs through described capper and arranges noumenally, the described screw rod middle part of taking the lead is provided with projection, and described capper body is provided with for limiting the up and down position-limited trough of this projection.
Above-mentioned projection is circular projection.
The above-mentioned description to structure of the present invention and method is known, compared to the prior art, tool of the present invention has the following advantages: hot pressing bar mounting groove is provided with the lifting mechanism that can control this hot pressing bar mounting groove bottom oscilaltion, by adjusting the oscilaltion of hot pressing bar mounting groove bottom with the degree of depth of adjustment hot pressing bar mounting groove, thereby the hot pressing bar that makes to be installed in hot pressing bar mounting groove can clamp mutually with corresponding heating platen, guarantee that capper carries out the working properly of sack oral area Heat Sealing.Meanwhile, can oscilaltion due to the bottom of hot pressing bar mounting groove, can reduce the accuracy requirement of the hot pressing bar to producing, reduce the reject rate of hot pressing bar.
Accompanying drawing explanation
Fig. 1 is the improved sealing machine structure schematic diagram of hot pressing bar mounting groove.
Fig. 2 is the enlarged drawing of A in Fig. 1.
The specific embodiment
The specific embodiment of the present invention is described with reference to the accompanying drawings.
As depicted in figs. 1 and 2, the improved capper of a kind of hot pressing bar mounting groove, comprises capper body 8 and the hot pressing bar mounting groove 9 that is installed in capper body 8, is equiped with resistant to elevated temperatures hot pressing bar (not shown) in this hot pressing bar mounting groove 9.Hot pressing bar mounting groove bottom 1 is equiped with the lifting mechanism 7 that can control this hot pressing bar mounting groove bottom 1 oscilaltion.Position corresponding with this hot pressing bar on capper body 8 is provided with heating platen (not shown), and hot pressing bar matches with heating platen the oral area Heat Sealing of sack.Hot pressing bar mounting groove bottom 1 is equiped with the lifting mechanism 7 that can control this hot pressing bar mounting groove bottom 1 oscilaltion, by adjusting the lifting of hot pressing bar mounting groove bottom 1 with the degree of depth of adjustment hot pressing bar mounting groove 9, thereby the hot pressing bar that makes to be installed in hot pressing bar mounting groove 9 can clamp mutually with corresponding heating platen, guarantee that capper carries out the working properly of sack oral area Heat Sealing.Meanwhile, can oscilaltion due to hot pressing bar mounting groove bottom 1, can reduce the accuracy requirement of the hot pressing bar to producing, reduce the reject rate of hot pressing bar.
As depicted in figs. 1 and 2, lifting mechanism 7 is to arrange like this: lifting mechanism 7 comprise be fixed at hot pressing bar mounting groove bottom nut 2 and with this nut 2 suitable take the lead screw rod 6.This is taken the lead screw rod 6 one end activities and is assemblied in this nut 2, takes the lead screw rod 6 other ends to run through the 8 ground settings of capper body.Taking the lead screw rod 6 middle parts is provided with circular protrudingly 3, and capper body 8 is provided with for limiting this circular protruding 3 up and down position-limited troughs 4.The position-limited trough 4 of taking the lead on circular protruding 3 on screw rod 6 and capper body 8 can limit takes the lead the position of screw rod 6, guarantees to take the lead screw rod 6 can not drop, and makes to take the lead in the process of screw rod 6 rotations, and the position of nut 2 can move up and down.Turn is taken the lead screw rod 6 and is stretched out the head 5 of one end of capper body 8, adjustable being sheathed on taken the lead the oscilaltion of nut 2 of screw rod 6 outsides, and nut 2 is to be fixed on hot pressing bar mounting groove bottom 1, so the oscilaltion of nut 2 can drive bottom 1 oscilaltion of hot pressing bar mounting groove.The degree of depth of hot pressing bar mounting groove 9 just changes along with the oscilaltion of hot pressing bar mounting groove bottom 1.
Above are only the specific embodiment of the present invention, but design concept of the present invention is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the present invention, all should belong to the behavior of invading protection domain of the present invention.
