Abstract
The utility model discloses the bottle base servo stretching device in straight line bottle blowing machine, comprise: frame, the top cross of frame is provided with servomotor, the output shaft of servomotor is provided with driving pulley, in frame below driving pulley, expansion bearing has driven pulley, between driving pulley and driven pulley, be provided with Timing Belt, the side side of Timing Belt is fixed with adjustable shelf, be vertically provided with some stretching bars in the outer end of adjustable shelf.The utility model has the advantages that: after (1) adopts servomotor synchronously to drive stretching bar, not only can realize any adjustment of the draw speed to stretching bar, substantially increase the Forming Quality of bottle, and eliminate gag lever post, reduce the production and application cost of enterprise; (2) adopt slide rail to carry out entirety guiding to gag lever post, because slide rail integral installation is in frame, and then the depth of parallelism between slide rail can not change in bottle base drawing process, substantially increases operation stability.
Description
Technical field
The utility model relates to the bottle base servo stretching device in straight line bottle blowing machine.
Background technology
Straight line bottle blowing machine is the common equipment in beverage filling production lines; equipment for blowing in straight line bottle blowing machine carries out in blow-moulding process to the bottle base be positioned in the die cavity of mold closing mechanism; bottle base stretching device is needed to carry out synchro-draw to bottle base, to guarantee to obtain the uniform bottle of bottle wall thickness (forming bottle after bottle base blow molding).The structure of the bottle base stretching device used at present is: comprise frame, at the top of frame, upper mounted plate is installed, some guide rods be parallel to each other vertically are provided with in the bottom of upper mounted plate, guide rod is provided with the lower portable plate that can move up and down along guide rod, upper mounted plate is vertically provided with lift cylinder, fix with lower portable plate after the piston rod of lift cylinder is passed down through upper mounted plate, the bottom even of lower portable plate is provided with some stretching bars, every root stretching bar is respectively to the die cavity of a lower aligning mold closing mechanism, also some gag lever posts are vertically provided with at the top of mold closing mechanism, when lift cylinder synchronously drives stretching bar to enter the die cavity of mold closing mechanism downwards, the top of gag lever post just in time withstands on lower portable plate.The shortcoming of above-mentioned bottle base stretching device is: (1), because the requirement of cylinder to source of the gas is high and source of the gas speed of expansion unstable, causes cylinder can not the draw speed of restrained stretching bar, greatly have impact on the global formation of bottle; (2) gag lever post must be set and encounter bed die excessively downwards to avoid stretching bar to enter mold closing mechanism, not only considerably increase enterprise's production and application cost, and after the mould of hyperphoric different size, all need the height and position readjusting gag lever post, considerably increase labor strength; (3) due to the bad control of the depth of parallelism between some guide rods, the lower jam phenomenon of portable plate on guide rod very easily occurs, and operation stability is low.
Utility model content
The purpose of this utility model is to provide a kind of stable and bottle base servo stretching device in the straight line bottle blowing machine of the draw speed of adjustable stretching bar.
For achieving the above object, the utility model have employed following technical scheme: the bottle base servo stretching device in described straight line bottle blowing machine, comprise: frame, the top cross of frame is provided with servomotor, the output shaft of servomotor is provided with driving pulley, in frame below driving pulley, expansion bearing has driven pulley, Timing Belt is provided with between driving pulley and driven pulley, the side side of Timing Belt is fixed with adjustable shelf, is vertically provided with some stretching bars in the outer end of adjustable shelf.
Further, the bottle base servo stretching device in aforesaid straight line bottle blowing machine, wherein: in the frame of Timing Belt both sides, be vertically provided with slide rail respectively, adjustable shelf is slided by sliding shoe and is arranged on slide rail.
By the enforcement of technique scheme, the beneficial effects of the utility model are: after (1) adopts servomotor synchronously to drive stretching bar, not only can realize any adjustment of the draw speed to stretching bar, substantially increase the Forming Quality of bottle, and eliminate gag lever post, reduce the production and application cost of enterprise; (2) adopt slide rail to carry out entirety guiding to gag lever post, because slide rail integral installation is in frame, and then the depth of parallelism between slide rail can not change in bottle base drawing process, substantially increases operation stability.
Accompanying drawing explanation
Fig. 1 is the structural representation of the bottle base servo stretching device in straight line bottle blowing machine described in the utility model.
Fig. 2 is the structural representation of the left apparent direction of Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, bottle base servo stretching device in described straight line bottle blowing machine, comprise: frame 1, the top cross of frame 1 is provided with servomotor 2, the output shaft of servomotor 2 is provided with driving pulley 3, and in the frame 1 below driving pulley 3, expansion bearing has driven pulley 4, is provided with Timing Belt 5 between driving pulley 3 and driven pulley 4, the side side of Timing Belt 5 is fixed with adjustable shelf 6, is vertically provided with some stretching bars 7 in the outer end of adjustable shelf 6; In the present embodiment, the frame 1 of Timing Belt 5 both sides is vertically provided with slide rail 8 respectively, adjustable shelf 6 is slided by sliding shoe 9 and is arranged on slide rail 8; In actual applications, only just can need be adjusted the draw speed of stretching bar by the rotating shaft rotating speed adjusting servomotor, and just can be limited the height and position of stretching bar by the rotation Lap Time of rotating shaft within the unit interval of adjustment setting servomotor, substantially increase operating efficiency; The utility model has the advantages that: after (1) adopts servomotor synchronously to drive stretching bar, not only can realize any adjustment of the draw speed to stretching bar, substantially increase the Forming Quality of bottle, and eliminate gag lever post, reduce the production and application cost of enterprise; (2) adopt slide rail to carry out entirety guiding to gag lever post, because slide rail integral installation is in frame, and then the depth of parallelism between slide rail can not change in bottle base drawing process, substantially increases operation stability.
Claims (2)
1. the bottle base servo stretching device in straight line bottle blowing machine, comprise: frame, it is characterized in that: the top cross of frame is provided with servomotor, the output shaft of servomotor is provided with driving pulley, in frame below driving pulley, expansion bearing has driven pulley, between driving pulley and driven pulley, be provided with Timing Belt, the side side of Timing Belt is fixed with adjustable shelf, be vertically provided with some stretching bars in the outer end of adjustable shelf.
