Description
Technical field
The present invention relates to package packing machine, what particularly relate to a kind of package bottle cap grabs lid and cap rotating device.
Background technology
Grab lid and cap rotating device to be provided with and to capture the grabbing device of bottle cap, and drive grabbing device to rotate and bottle cap screwed in the cap rotating device on packaging bottleneck.Existing structural representation of grabbing lid and cap rotating device as shown in Figure 1, 2, 3, comprise spiral cover arm component, drive the cam 101 of spiral cover arm component dipping and heaving, with spiral cover arm component motion Cao rotating head assembly and grab headkerchief assembly, spiral cover arm component comprises can the spiral cover arm 102 of rotation, spiral cover arm 102 is driven by cam 101 and moves up and down, and spiral cover arm 102 is built with tween drive shaft 103, Cao rotating head assembly comprises the Cao rotating head housing 104 connected below spiral cover arm 102, upper end pushes against interlude 103 bottom and transmits the adapter shaft 105 of downward motion, the adapter shaft retracing spring 116 ordering about adapter shaft and rise is provided with between Cao rotating head housing 104 and adapter shaft 105, bolt 106 is equipped with in adapter shaft 105 lower end, pipe link 107 is equipped with in bolt 106 lower end, grab headkerchief assembly and comprise the top pressure nut 108 that the composition be connected to below Cao rotating head housing 104 grabs headkerchief housing and the sliding key sleeve 109 of pressing nut 108 to be connected with top, be equipped with below sliding key sleeve 109 grab lid main body 115 and with grab lid main body 115 coordinate capture bottle cap grab lid finger 110, sliding key sleeve 109 is built with top stem casing 111 and the push rod 112 be placed in top stem casing 111, and top stem casing 111 upper end to be placed in Cao rotating head housing 104 and to be connected with pipe link 107, the lower end of push rod 112 protrudes to push against outside top stem casing 111 and drive and grabs lid finger 110 and open, also have and connect top stem casing 111 and grab lid finger 110 and drive the finger retracing spring 113 of grabbing lid finger 110 and closing up, grab the limiting stopper 114 lid main body 115 being also provided with and limiting bottle cap position.
During work, cam driven spiral cover arm declines, tween drive shaft in spiral cover arm then drives adapter shaft, bolt, pipe link, push rod to move successively, grab lid finger by pressure handle under push rod again to open, after bottle cap enters the crawl position of grabbing lid finger, cam driven assembly rises, grab lid finger and firmly grasp bottle cap under the screen resilience of finger retracing spring, and then make itself and bottleneck docking also with the rotary motion of spiral cover arm, bottle cap be screwed in Packaging Bottle by cam driven, grab lid finger afterwards to open and get back to initial condition, complete with this and grab lid and spiral cover work.But in this process, cam transmission campaign needs finally to be delivered to push rod through more than one piece workpiece such as tween drive shaft, adapter shaft, bolt and pipe links, and in Cao rotating head housing without any spacing or guide frame ensure its transmission process, this kind of Multi-stage transmission is easily because the accumulation of error causes particularity to reduce, cap rotating machine centering is caused to be forbidden, bottle cap can not accurately screw in Packaging Bottle, and then affects production work and product design; Moreover cap rotating machine frequency of operation is high, Multi-stage transmission process does not have again spacing or guide frame, causes the Joint strenght between part low, equipment work speed must be reduced to ensure production safety, and this greatly affects production efficiency.
Summary of the invention
The present invention aim to provide a kind of centering accurately and Joint strenght high grab lid and cap rotating device, with improve production efficiency and product quality.
Of the present invention grabbing is covered and cap rotating device, comprise the adapter shaft of Cao rotating head housing and transmission downward motion, the connecting screw rod that outer wall is adjacent to the mandrel inwall of Cao rotating head housing is provided with in Cao rotating head housing, end face and the bottom surface of connecting screw rod all have shrinkage pool, and the shrinkage pool of bottom surface is provided with negative thread, the lower end of adapter shaft is placed in the end face shrinkage pool of connecting screw rod, cover is had to have the push rod screw rod of push rod, the upper end of push rod screw rod is provided with outside thread and is connected and fixed with the shrinkage pool of connecting screw rod bottom surface, two nuts mutually pushed against the outer wall of push rod screw rod are equipped with, also has the retracing spring driving push rod screw rod to rise, the two ends of retracing spring connect the nut of the lower end outside push rod screw rod respectively and grab lid main body.
Of the present invention grabbing is covered and cap rotating device, tween drive shaft drives push rod screw rod to decline by connecting screw rod, and then drive push rod to order about to grab lid finger and open, in this motion process, the mandrel inwall of connecting screw rod and Cao rotating head housing is adjacent to and produces relative motion, and the mandrel inwall of Cao rotating head housing forms spacing and directional tagging to connecting screw rod.When needing adjustment to grab the promptly dynamics of lid finger, rotating two nuts outside push rod screw rod, by the deformation quantity of the change adjustment retracing spring of its position, and then changing the promptly dynamics of grabbing lid finger.The connecting screw rod end face of this device and bottom surface are equipped with shrinkage pool, and the end of adapter shaft and push rod screw rod is placed in it respectively, and its Joint strenght is high, and can limit the centering position between bar and bar, reduce issuable magnitude of error, improve and grab lid centering accuracy; Meanwhile, the diameter of connecting screw rod is comparatively large, and is adjacent to the mandrel inwall of Cao rotating head, forms the spacing and directional tagging of actv. between the two, avoids the generation of deviation, drastically increase the accuracy of centering, and enhance its Joint strenght; The nut that push rod screw rod is arranged, make the dynamics of firmly grasping of grabbing lid finger adjustable, improve its applicability, and the setting of double nuts significantly enhances the stationarity of nut on push rod screw rod, ensure that its work is accurate, stable, moreover, the setting of outer nut can increase the diameter at this place, reduce the gap between push rod screw rod and Cao rotating head housing, produce certain spacing and directional tagging, improve centering accuracy and the Joint strenght of device further.
