A kind of plastic cup cover thermoforming machine
Technical field
The present invention relates to a kind of plastic cup cover thermoforming machine.
Background technology
At present, the one-tenth of the bowl cover class plastic such as beverage cup lid, coffee cup cover, drug and food pallet (ps, pet, pvc etc.)
Type manufacture method is: first with unwinding device, coiled plastic material is unreeled and is formed plastic sheet;This plastic sheet passes through again
Heater and heat and soften, (this operation is passed through then to be processed into bowl cover shape plastic sheet through die shaped device again
Plastic uptake thermoforming machine completes);Again through being manually made up the bowl cover semi-finished product of single-piece of blanking apparatus;Then, then by artificial
Operation is punched out molding (generally rushing a hole or two holes) by punch press and makes bowl cover finished product to this bowl cover semi-finished product.
Common plasticses bowl cover thermoforming machine cannot produce the plastic of pp material, because the plastic sheeting of pp material is usual
Take contact heating (i.e. thin film is adjacent to heating plate), and after pp heating and softening, viscosity is big, can stick to heater plate surface, so
After being pulled by traction apparatuss again, will result in material and tear it is impossible to complete shaping work.

To save manual physical.
Brief description
The main view figure structure schematic representation of Fig. 1 present invention.
Specific embodiment
Shown in Fig. 1, it is related to a kind of plastic cup cover thermoforming machine, including frame 1, this frame 1 is provided with and moulds for conveying
The supply unit 4 of material thin slice 3, for driving the Motorized drive unit of each device work, and for each device of unified regulation and control
Panel control unit 10;The input side of described supply unit 4 is disposed with to outlet side: unwinding device 2, and it is used for plastics
Coiled material is unreeled and is formed plastic tab 3;Adjustable chain clamp mechanism 18, it is used for for plastic tab 3 being suspended on described conveying list
The top of unit 4;Baking oven heater 6, it is used for carrying out heating and softening process to plastic tab 3;Mould molding device 7, its use
In plastic tab 3 is processed into bowl cover shape plastic sheeting;Hole punched device 9, it is used for bowl cover shape plastic sheeting being punched out locate
Reason;Blanking apparatus 13, the bowl cover finished product of single-piece made by its bowl cover shape plastic sheeting after being used for processing punching;Waste material winding dress
Put 11, it is used for carrying out winding process to remaining bowl cover shape plastic sheeting waste material;Pusher air cylinder device 12, it is used for bowl cover
It is pushed under finished product on conveyer 14, exported by conveyer 14.Wherein, accurately synchronous in order to be able to realize to bowl cover shape plastic sheeting
Transmission, the supply unit 4 between mould molding device 7 and hole punched device 9 is additionally provided with chain folder haulage gear 8.Baking oven adds
It is additionally provided with the baking oven lift cylinder 5 driving baking oven heater 6 down or up above thermal 6.Baking oven heater 6 is then
Using infrared radiation mode, plastic tab 3 is heated.Mould molding device 7 therein includes the molding being arranged below
Lower mould 72, and be disposed over cooperatively forming the air blowing plate 71 of airtight die cavity with mould under molding 72.Hole punched device 9 therein wraps
Include the punch upper die 91 being disposed over being driven by punch upper die cylinder 90, and be arranged below matching with punch upper die 91
Punching under mould 92.Blanking apparatus 13 therein include mould 131 on the punching that is disposed over, and are arranged below and are punched
Mould 132 under the punching that upper mould 131 matches.Motorized drive unit in the present invention includes mair motor 15, and mair motor 15 passes through to subtract
Fast case 16 is connected with final drive shaft 17, final drive shaft 17 respectively with mould molding device 7, hole punched device 9 and blanking apparatus 13
In cam drive connect.Wherein, encoder and reset photoelectric subassembly 171 are also provided with final drive shaft 17.
Operation principle is: drives reduction box 16 by mair motor 15 by V-shaped band, final drive shaft 17 runs through reduction box 16 and exports
Hole, drives operating by reduction box 16.When equipment starts, it is arranged on the automatic bottom of uncoiling Kun 24 on unwinding device 2, and passes through
Feeding cylinder 23 drives upper flitch 21 bottom, by a coiled plastic material 20 as the top of upper flitch 21, then is carried by feeding cylinder 23
Move and put on flitch 21 on this, coiled plastic material 20 is promoted to certain altitude, automatically falls into and unreel on seat 22, so that coiled plastic material is in
Relaxed state (is conducive to traction to reduce resistance), thus can be unreeled coiled plastic material and be formed plastic tab 3;Plastics
Thin slice 3 passes through the top being fixed on supply unit 4 that adjustable chain clamp mechanism 18 hangs, and plastic tab 3 so can be made to hang in the sky,
Not with heating thing directly contact, thus avoid adhesion.Plastic tab 3 drives interval to move ahead by adjustable chain clamp mechanism 18,
Through baking oven heater 6(, it is driven by baking oven lift cylinder 5 and moves down) carry out heating and softening process;Then enter back into mould
Tool shaped device 7 is processed into bowl cover shape plastic sheeting;And work as mould 72 under the molding in mould molding device 7 and rise, molding can be made
Lower mould 72 and air blowing plate 71 closure form airtight die cavity, the plastic sheeting of softening be under molding mould 72 and air blowing plate 71 it
Between, under molding, mould 72 bottom is equipped with steam vent, has air blowing plate to be passed through air pressurized, makes plastic tab 3 top pressure be more than lower section,
Plastic tab 3 pressure of softening is attached on mould 72 surface under molding, inside mould 72 under molding, is connected with cooling water, plastic tab 3 warp
Bowl cover shape plastic sheeting is formed by mould under molding 72 cooling and shaping, now under molding, mould 72 moves down, make under molding mould 72 with
Air blowing plate 71 separates, and the bowl cover shape plastic sheeting obtaining is carried by adjustable chain clamp mechanism 18 and is punched out processing to hole punched device 9;Should
Hole punched device 9 includes being disposed over the punch upper die 91 being driven by punch upper die cylinder 90, and is arranged below and punching
Mould 92 under the punching that upper mould 91 matches.During work, under punching, mould 92 rises to peak, and now, punch upper die 91 is by punching
Upper mould cylinder 90 is driven and moves down so as to be engaged with mould under punching 92 with punch upper die 91, washes out a block of material, completes punching.Again
Carry to blanking apparatus 13 the bowl cover finished product that bowl cover shape plastic sheeting is made single-piece by adjustable chain clamp mechanism 18;This blanking apparatus 13
Including mould 131 on the punching being disposed over, and it is arranged below and is punched mould 132 under the punching that upper mould 131 matches.Work
When making, the lower mould 132 of punching rises, and so that mould 132 and the upper mould 131 of punching under punching is engaged, can drop down onto the punching of bowl cover finished product under punching
In mould 132, bowl cover finished product, by being pushed under pusher air cylinder device 12 on conveyer 14, finally has conveyer 14 to export.And after processing
Waste material then winding process is carried out by waste material wrap-up 11.When machine down, baking oven for heating is driven by baking oven lift cylinder 5
Device 6 rises, and so allows for baking oven heater 6 away from plastic sheeting, so as not to over-heating so that thin film is overbated sagging,
Causing can not normally molding.
