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 the capper body and is installed in the hot pressing bar mounting groove of capper body, be equiped with resistant to elevated temperatures hot pressing bar in this hot pressing bar mounting groove, position corresponding with this hot pressing bar on the capper body is provided with heating platen, and the 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, between hot pressing bar and heating platen, can be difficult to clamp, 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, so that the degree of depth that overcomes hot pressing bar mounting groove in prior art is fixing, can not adjust, and is difficult to clamp the problem that the reject rate of hot pressing bar is high 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 the capper body, be equiped with the hot pressing bar in this hot pressing bar mounting groove, 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 at least one nut of being fixed at described hot pressing bar mounting groove bottom and with described nut suitable take the lead screw rod, this is taken the lead screw rod one end activity 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, the present invention has following advantage: hot pressing bar mounting groove is provided with the lifting mechanism that can control this hot pressing bar mounting groove bottom oscilaltion, oscilaltion bottom adjustment hot pressing bar mounting groove is to adjust the degree of depth of hot pressing bar mounting groove, thereby the hot pressing bar be installed in hot pressing bar mounting groove can be clamped mutually with corresponding heating platen, guarantee that capper carries out the working properly of sack oral area Heat Sealing.Simultaneously, but, due to the bottom oscilaltion 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.
The accompanying drawing explanation
Fig. 1 is the improved sealing machine structure schematic diagram of hot pressing bar mounting groove.
The enlarged drawing that Fig. 2 is 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, comprise 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 the heating platen (not shown), and the 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, bottom adjustment hot pressing bar mounting groove, 1 lifting is to adjust the degree of depth of hot pressing bar mounting groove 9, thereby the hot pressing bar be installed in hot pressing bar mounting groove 9 can be clamped mutually with corresponding heating platen, guarantee that capper carries out the working properly of sack oral area Heat Sealing.Simultaneously, but, due to bottom 1 oscilaltion 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.
As depicted in figs. 1 and 2, lifting mechanism 7 is to arrange like this: lifting mechanism 7 comprise nut 2 being fixed at hot pressing bar mounting groove bottom 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 trough 4.Position-limited trough 4 on circular protruding 3 and the capper body 8 of taking the lead on screw rod 6 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 an end of capper body 8, can regulate to be sheathed on and take 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.
