Description
Technical field
The utility model relates to a kind of automated production equipments, more particularly, to a kind of hard Capsules notching device.
Background technique
Currently, well known full-automatic hard hollow capsule production line is (hereinafter referred to as automatic using full machine driving automatic machine
Machine) realize demoulding, the fixed length, notch, fitting process of hard Capsules.Automatic machine is with hard Capsules body, cap side
The installation production of separation type box body component, motor is at the uniform velocity rotated by shaft coupling driving body, cap side automatic machine main shaft notch cam
Process forms stroke drop, linkage Lengthened moment arm swing rod and fulcrum using the operation curve for reducing rotating concentric circle to pass in the middle
It is dynamic, realize the horizontal movement of cutting-off tool rest.As shown in Fig. 1 in Figure of description, on host header, cutter supporter 14 is mounted on preceding branch
Frame component 5, the bilateral reciprocation on fore-stock component 5 of cutter supporter 14.The upper end of swing rod 10 passes through cutter swing link bracket 15
It is fixedly connected with cutter supporter 14, lower end is connected with camshaft bearing 16.Cam 17 contacts matching with camshaft bearing 16.Pendulum shaft
11 pass through the lower part of swing rod 10, and swing rod 10 is flexibly connected with pendulum shaft 11.12 one end of tension spring is connect with the upper end of swing rod 10, another
End is fixedly connected on fore-stock component 5.Cam 17 rotates, and under the action of tension spring 12, drives swing rod by camshaft bearing 16
10 are swung with pendulum shaft 11 for fulcrum, to drive 14 side-to-side movement of cutter supporter.
Rack gear push rod 13 is linked with transmission shaft component 6, and transmission shaft component 6 can be made to rotate, make cylinder by lifter rack 18
The rotation of clip tooth wheel shaft.
Mandril 7 is used to eject capsule redundance outside collet chuck.
However, there are following disadvantage and hidden danger for the mechanism:
(1) mounting and adjusting is difficult
When mounting and adjusting due to be tension spring is added using Lengthened moment arm swing rod and fulcrum come be driven realize cutting-off tool rest level
Movement, leads to manually adjust that cutter entrance error is big, and detection is insufficient, and cutter is caused to shake, and makes capsule notch that wire drawing phenomenon occur,
Qualification rate is not high.
(2) entire host header kinetic stability is low
Lengthened moment arm swing rod and fulcrum come realize cutting-off tool rest horizontal movement and plus tension spring movement mechanism operational process
In the middle, the fulcrum position to the left or to the right in host header forms a horizontal torsion to host header, host header is caused to rise
It is whole unstable in drop operation；And this torsion also forms a horizontal force to four lifting columns of connection host header,
In lifting operational process when axis and set side stress, axis and set abrasion are caused, the service life of set, movement clearance are seriously affected
Greatly, cause capsule manufacture qualification rate low.
(3) there are security risks for Maintenance and Repair complexity
Machine components are various, and repair and maintenance is complicated, and operator's study, adjustment are difficult, and go wrong difficulty in operational process
It is solved with analyzing, increases after cost indirectly.Tension spring be easy to cause fatigue in prolonged and repeated drawing process, and fracture occurs and causes
" colliding " accident, there are also the bearings on Lengthened moment arm swing rod, and " great-jump-forward " is run repeatedly in operational process, will cause bearing
Axis fatigue fracture causes " colliding " accident, not only causes damages to production, and will also result in fatal beat to host header itself
It hits and loses.
Summary of the invention
The utility model is pacified to solve existing full-automatic hard hollow capsule production line using full machine driving automatic machine
Adjustment it is whole it is difficult, host header kinetic stability is low, Maintenance and Repair are complicated there is technical issues that, a kind of structure is provided
The hard Capsules notching device that simple mounting and adjusting is convenient, kinetic stability is high, Maintenance and Repair are safe and reliable.
Hard Capsules notching device provided by the utility model, including knife rest main body, deceleration machine support, rack gear, tooth
Wheel, speed reducer and servo motor, speed reducer are connect with deceleration machine support, and the output shaft of servo motor is connect with speed reducer, gear
With the output axis connection of speed reducer, rack gear is fixedly connected with knife rest main body, and wheel and rack engagement, knife rest main body is connected with straight line
Guide rail.
It preferably, further include fore-stock, fore-stock is connect with linear guide, and the connection of deceleration machine support is mounted on fore-stock
On.
The beneficial effects of the utility model are:
(1) machine components are reduced, is driven using simple structure machine driving instead of multi-stage mechanical, reduces mechanical friction pair,
Kinematic accuracy is improved, accumulated error is reduced, host header overall stability is improved, improves the service life of entire automatic machine, have
Conducive to plant maintenance and maintenance, oil site is reduced, no oil pollution meets production requirement.
(3) it replaces cam Lengthened moment arm swing rod and fulcrum to be driven using the characteristic of servo motor high-precision controllability, mentions
High cutting-off tool rest kinematic accuracy, reduces transmission, and the torsion of elimination of level realizes the accurate notch of cutter, makes the accurate fitting of capsule, mention
High production efficiency, improves capsule manufacture qualification rate.
The utility model further feature is clearly stated that in the description of following specific embodiments.
