Description
Technical field
The present invention relates to packing machinery technology, particularly relate to a kind of pump cover grasping mechanism.
Background technology
Pump cover is due to easy to use, and the pressing head that only need press pump cover with hand when taking just can liquid in quantitative bottle outlet, is widely used in the industries such as daily use chemicals, food, medicine.
In automatic packaging process, to bottle is filling complete after feeding subsequent processing bottle cap is screwed on bottleneck, complete the packing of product, therefore, the crawl of pump cover is one important operation.Adopt pawl head to capture pump cover in prior art, utilize actuating device to move by driving claw head, thus capture bottle cap.Before crawl, because the liquid outlet of pump cover is towards being arbitrary, to subsequent handling, as: spiral cover and packaging etc. all have impact, can not ensure that the pump cover assembled is whole facing one direction, cannot complete packaging.The riko cover of existing pump cover is completed by hand by operator, and production efficiency is low, and operator's labour intensity is large, is difficult to the needs adapting to high-speed production; And pump cover is easily polluted, affect the cleanliness level of pump cover lid.
Summary of the invention
Technical matters to be solved by this invention is: in order to overcome deficiency of the prior art, the invention provides a kind of pump cover grasping mechanism, what adopt pump cover attitude reference device adjustment pump cover goes out mouth direction, makes all pump covers to be installed go out mouth direction and is consistent, to facilitate the installation of subsequent handling; Friction force between during employing cambered surface relative motion makes claw realize the crawl of pump cover, and two kinds of structures combine and further increase work efficiency, solve the pollution problem that manual operation brings.
The present invention solves the technical scheme that its technical matters will adopt: a kind of pump cover grasping mechanism, comprise pawl seat, described pawl seat is circumferentially with multiple claw, described pawl seat inside is provided with mandrel, described mandrel extends described pawl seat respectively to upper and lower two ends, described mandrel lower end is provided with pump cover attitude reference device, described pump cover attitude reference device is positioned at the bottom of described pawl seat, described pump cover attitude reference device comprises the flange sleeve be arranged on outside mandrel, described flange sleeve lower end is provided with flange, and the bottom surface of described flange is provided with pin.
Rotarily drive flange sleeve by mandrel to rotate together, thus make pin also along with flange sleeve is rotated, when pin in rotation process run into pump cover go out mouth after, pump cover can be promoted and rotate together, until make pump cover go out mouth turn to predeterminated position direction, then stop operating, realize the adjustment that pump cover goes out mouth direction, adopt machine automatization adjustment, the conformability of each adjustment position is high, facilitate subsequent handling, enhance productivity.
Further, described pump cover attitude reference device also comprises the Lower shaft sleeve be arranged between described mandrel and flange sleeve, described Lower shaft sleeve is set on described mandrel, and the outer wall of described mandrel is provided with retainingf key, and described Lower shaft sleeve inwall is provided with the keyway coordinated with described retainingf key.
Further, described Lower shaft sleeve is provided with the pillar stiffener with described Lower shaft sleeve axes normal, and described pillar stiffener stretches out and runs through the sidewall of described flange sleeve, and described pillar stiffener is two, and is provided with spring between described pillar stiffener.
Further, described pump cover attitude reference device also comprises the backup bearing be arranged between described mandrel and flange sleeve, and described backup bearing is positioned at below described Lower shaft sleeve.
Be connected by retainingf key between mandrel with flange sleeve, flange sleeve is rotated with mandrel simultaneously, and in addition, also the gap in mandrel and flange sleeve rotation direction eliminated by employing pillar stiffener and spring, and play a supporting role, be applied to the shearing force on retainingf key when sharing rotation.In order to strengthen the stability that flange sleeve is connected with mandrel further, be also provided with backup bearing.
Further, being arranged with outside the mandrel in described pawl seat can the Upper shaft sleeve of up-and-down movement, and the outer wall of described Upper shaft sleeve lower end is cambered surface, and the point in described cambered surface reduces from top to bottom gradually to the distance of described Upper shaft sleeve axis; The coupling end side of described claw and described pawl seat is provided with antifriction-bearing box, and the excircle of described antifriction-bearing box coordinates with described cambered surface.
Further, described Upper shaft sleeve outer wall is arranged with recovery spring.
Upper shaft sleeve up-and-down movement can be made by driver train, when Upper shaft sleeve moves downward, compression recovers spring, and the cambered surface of Upper shaft sleeve contacts with the excircle of antifriction-bearing box, produce pressure between, thus produce friction, under the effect of friction force, make antifriction-bearing box upwards rotate in axle sleeve direction, by the rotation of antifriction-bearing box, claw is opened, then the position moving to pump cover prepares to capture pump cover, after claw puts in place, driver train stops driving Upper shaft sleeve, then Upper shaft sleeve upward movement under the effect recovering spring, Upper shaft sleeve is separated with antifriction-bearing box makes claw catch pump cover, thus realize the crawl of whole pump cover.
Concrete, described claw is three, and be uniformly distributed along described pawl seat circumference, the angle between adjacent claw is 120 °.Three claws make pump cover capture more firmly, more stable.
The invention has the beneficial effects as follows: a kind of pump cover grasping mechanism provided by the invention, what adopt pump cover attitude reference device adjustment pump cover goes out mouth direction, makes all pump covers to be installed go out mouth direction and is consistent, to facilitate the installation of subsequent handling; Friction force between during employing cambered surface relative motion makes claw realize the crawl of pump cover, and two kinds of structures combine and further increase work efficiency, ensure that the clean of product and quality.
