Description
Technical field
The present invention relates to plastic bottle spiral cover apparatus field, specifically a kind of plastic bottle spiral cover gripping finger and its method of work.
Background technology
In the spiral cover capping processes of plastic bottle, screw capping with bottle cap and bottle cap screwing plastic bottle opening spiral shell
On line；Therefore, it is necessary to a devices to fix body, prevents it from being rotated during spiral cover, while also play the biography of plastic bottle
The effect of passing.
The device of body is fixed in plastic bottle spiral cover equipment, mainly there are following 2 kinds of forms at present：
A. semicircle rotation stop knife and bottleneck supporting plate combination, are shown in Fig. 5 and Fig. 6：The point of a knife of semicircle rotation stop knife is upward, plastic bottle
A shoulder part fall on point of a knife, on the upper bottleneck supporting plate of another part support；Due to semicircle rotation stop knife and bottleneck supporting plate simultaneously
Plastic bottle is not completely fixed, the lower half portion of body can rock, and come so body star-wheel must be added with body backplate
The lower part of righting body.Advantage is simple in structure, and part manufacturing cost is low.Shortcoming is：1. when bottle diameter changes, bottle is needed replacing
Body star-wheel and body backplate；2. when plastic bottle is non-circular bottle（Such as rectangular bottle, rectangle bottle）When, body star-wheel, body backplate with
Gap needs between body are larger, and a bottle effect is helped to substantially reduce；3. during spiral cover, screw capping need to apply bottleneck compared with
Big lower pressure, otherwise can skid between plastic bottle and rotation stop knife；But larger lower pressure can cause larger between bottle and lid
Frictional resistance, influence the stabilization of spiral cover torque.
B. double acting gripping finger type, is shown in Fig. 7 and Fig. 8：Rotation stop knife is respectively arranged in active gripping finger, driven gripping finger, point of a knife is level side
To being clamped on the bottleneck of plastic bottle.Active gripping finger, driven gripping finger are engaged by synchromesh gear, synchronous backward rotation.Advantage is：
1. body consolidates, do not need to body star-wheel and body backplate when clamping, bottle-type side is replaced more；2. pair round bottle and non-circular bottle are same
Sample is suitble to；3. the pressure of screw capping can be smaller during spiral cover, screw capping torque is stablized.Shortcoming is：1. it is complicated, it is manufactured into
This height, because the part of gripping finger is generally made of austenitic stainless steel（It needs corrosion-resistant）, synchromesh gear need carry out Surface hardened layer
Processing；2. because two gripping fingers are all in rotation, the concentricity adjustment between bottleneck and screw capping is relatively difficult；Gear grinding
Damage, the abrasion of rotation stop knife can all influence concentricity.3. the strength needed for fastening spring is larger, gripping cams are easily ground with pinching roller
Damage.
Invention content
The present invention provides a kind of plastic bottle spiral cover gripping finger and its method of work, fits to solve problem of the prior art
For conjunction round vase with being not required to adjust when non-round vase, replacement bottle-type, service life is long, reliable, and manufacture is easy to process, adjusts easily, cost
It is relatively low.
The present invention provides a kind of plastic bottle spiral cover gripping fingers, are included in the star wheel disc in live spindle outer rim and are connected to
Quiet gripping finger and dynamic gripping finger on star wheel disc, the quiet gripping finger are fixed on by bolt and positioning pin on star wheel disc.Described is dynamic
It moves gripping finger towards horizontal rotation stop knife equipped with point of a knife in gripping finger and is mounted on by shaft on the axis hole of star wheel disc, is equipped in axis hole
First sliding bearing, dynamic gripping finger and is fixed between the spring hanging column on star wheel disc and is connected with opening spring, and opening spring makes
Gripping finger, shaft generate a torque counterclockwise；The shaft middle and lower part be cased with the upper swing arm separated by sliding shim and
Lower swing arm, wherein, upper swing arm is fixed by bolt and shaft, and lower swing arm one end is connect by the second sliding bearing with shaft, separately
One end is connected with pinching roller by roller shaft, and the lower section of star wheel disc is equipped with fixed gripping cams, and pinching roller is convex along clamping
Wheel surface rolls.
It is further improved, pull rod is fixed on the upper swing arm, one end of fastening spring is pressed on pull rod by nut
On, the other end is fixed on lower swing arm, the compression degree of fastening spring 20 can be adjusted by adjusting nut 21 dynamic gripping finger and
Clamping force between quiet gripping finger.
It is further improved, the rotation stop knife is deflected outward along plastic bottle opening tangential direction.Rotation stop knife is not disposed at
Tangential direction, but be deflected outward certain angle, during spiral cover, screw capping acts on the torsion on rotation stop knife by bottleneck, makes
Gripping finger must be moved and be intended to the direction compressed.
The present invention also provides a kind of method of work of plastic bottle spiral cover gripping finger, star wheel disc rotations, when pinching roller is gone to
The protrusion timesharing of gripping cams, pinching roller drive lower swing arm rotationally clockwise, and lower swing arm compression fastening spring passes through
Nut, pull rod drive upper swing arm, shaft, dynamic gripping finger to be rotated in the clockwise direction together, move gripping finger and quiet gripping finger plastic bottle
Bottleneck clamps；When pinching roller goes to the recessed portion of gripping cams, under the action of spring is opened, gripping finger side counterclockwise is moved
To rotation, plastic bottle gripping finger is opened.When nut compresses fastening spring, the clamping force increase between gripping finger and quiet gripping finger is moved.
Advantageous effect of the present invention is：
1st, being suitble to round vase, service life is long, reliable, and manufacture is easy to process, adjusts with being not required to adjust when non-round vase, replacement bottle-type
Lift face is easy, and cost is relatively low.
2nd, clamping force is easy to adjust.
