The alkaline Mn cell sealing machine
The utility model relates to a kind of alkaline Mn cell sealing machine, belongs to plant equipment.
Existing alkaline Mn cell sealing machine has cover envelope formula and revolves two kinds of types of envelope formula.Their basic structure pattern is to be made of capstan head and conveyer belt, and treating in advancing with conveyer belt sealed battery and by two the capstan head that changes clamped, and by being installed on the cover end socket on the capstan head or revolving end socket it carried out sealing operation simultaneously.Its weak point is, because during sealing operation, battery to be sealed is in ceaselessly motion, seal will be in dynamic process moment finish, therefore, require once to seal moulding, and once can only process a battery.Cover envelope formula sealing machine because once cover envelope moulding needs impulse force bigger, adopts 10 tonnes press device usually, equipment heaviness not only, and volume is big, and the chap of sealing end housing distortion, needs to increase to pull out straight operation together and give shaping.Shaping can cause again seals distortion, causes poorly sealed and problem that leak.Revolve envelope formula sealing machine, owing to once revolve the envelope moulding, it is bigger to seal deformation ratio of crimping, and remaining residue stress makes it bounce-back after the moulding, easily small slit occurs at sealing part, causes leaking.Poorly sealed, easily leaking is the existing hard nut to crack that envelope formula sealing machine can't overcome of revolving.
The purpose of this utility model is to provide a kind of good seal, does not leak, and is indeformable, and volume is little, in light weight, the alkaline Mn cell sealing machine that efficient is high.
The basic ideas of the utility model technical solution are, once seal moulding and change into and seal moulding more than twice or twice existing, improve the efficient of equipment simultaneously.For this reason, we have taked the technical scheme that the part technology in the fully-automatic capsule filling machine (ZL98210915.6) that Dandong City gold ball company produces combines with closing device.Disclosed fully-automatic capsule filling machine partly is made up of capsule dispensing mechanism, medicinal powder feeding machanism, metering device, control cubicle, power drive mechanism, indexing case, turntable, upper plate etc. in ZL98210915.6, and its intermediate station is made up of rotation skeleton and module up and down mounted thereto.The rotation skeleton is fixedlyed connected with the spindle nose on being installed on upper plate, and is connected with the output shaft of indexing case by spindle nose, constitutes intermittent-rotation mechanism; Upper module is fixedly mounted on the rotation skeleton by rotating disk; But lower module by slide, vertical shaft, the lifting of slide bar vertical and radial expansion be installed in the rotation skeleton on.The dish cam directly is fixedly mounted on the upper plate, its working face up, working face is provided with the end face track of control lower module elevating movement and the matrix conduit of control lower module radial expansion, respectively with slide on roller be connected with rolling bearing on the slide bar.The utility model has adopted turntable and the part technology relevant with turntable, and two or more mutual independences are installed on upper plate and are the closing device of fixing.Concrete scheme of the present utility model is described below:
Comprise the alkaline Mn cell sealing machine of upper plate, indexing case, power drive mechanism, control cubicle, it is characterized in that:
The rotation skeleton of a, turntable is fixedlyed connected with the spindle nose on being installed on upper plate, and by spindle nose be connected with the output shaft of indexing case;
B, dish cam directly are fixedly mounted on the upper plate, its working face up, working face is provided with the matrix conduit that the control inner module is done radial expansion motion; Inner module is fixedly mounted on the outer end of slide bar, slide bar can be installed on the slide along horizontal radial by linear bearing movably, slide is fixedly mounted on the rotation skeleton, the other end of slide bar is fixedlyed connected with vertical pull bar, rolling bearing is installed in the lower end of pull bar, and rolling bearing cooperates with the matrix conduit of dish cam;
C, outer module are fixedly mounted on an end of slide bar, and slide bar is installed on the slide by linear bearing, and the other end of slide bar is connected with the piston rod of cylinder, and slide is fixedly mounted on the upper plate, and make outer module corresponding with inner module;
D, on upper plate, be installed with two or more closing device.
The utility model has the advantages that: because the utility model is by the intermittent-rotation mechanism with multistation with place on the different station independent and fixing mutually closing device to form.Battery to be sealed is carried by slew gear and does intermittent movement, forward another station to by a station, and on each station, stop certain hour, meanwhile it is implemented sealing operation by the closing device that is fixedly set on this station, therefore can implement repeatedly to seal to same battery, the advantage of this structure is: if setting is the cover seal apparatus, can change the R and the diameter of phi of the cover end socket working face on the different station, make it progressively moulding, reduce the stamping press of each cover envelope, guarantee that housing is indeformable, can not only save and pull out straight operation, also can avoid owing to pull out the new leakage problem that straight operation causes.Because impulsive force is little, do not need heavy pressing equipment, can satisfy arts demand with cam link mechanism, make equipment volume little, in light weight, cost is low.If what be provided with is to revolve seal apparatus, can make and seal progressively moulding by adjusting the position of revolving end socket on the different station, the deflection that reduces at every turn to seal makes that crimping is more smooth and does not rebound, thereby avoids leakage problem.All closing devices of the present utility model are worked simultaneously, are to carry out on different station and same battery is implemented repeatedly to seal, and repeatedly sealing does not influence device efficiency; Of the present utility model sealing is to carry out under static relatively state, so a station last time can be processed a plurality of batteries, thereby can increase substantially efficient; And compared with prior art, sealing the active force time lengthening, crimping is abundant, is difficult for bounce-back, improves seal quality; The utility model can be provided with the cover seal apparatus becomes cover envelope formula sealing machine, is provided with to revolve envelope formula closing device and become and revolve envelope formula sealing machine, and two kinds of closing devices also can be set simultaneously to be become the cover envelope, revolve the hybrid sealing machine of envelope; The utility model need only be changed the alkaline Mn cell that the module specification can be processed different size owing to adopted modular structure, and a set of equipment is produced the alkaline Mn cell of multiple different size, and this is out of the question at all to existing same category of device.
