Abstract
The utility model discloses a stripper device for a plastic cup cover, which comprises a forming concave mould (5) and a forming air blowing mould (3). The forming air blowing mould (3) is mounted on the machine body of a plastic cup cover former; and the forming concave mould (5) is connected with a transmission mechanism. The stripper device is characterized in that a stripper plate (4) matched with the forming concave mould (5) is arranged on the forming concave mould (5); and an elastic device is arranged between the stripper plate (4) and the forming concave mould (5), so that the stripper plate (4) can be separated from the forming concave mould (5) under the action of no external force. Because the elastic device is arranged between the stripper plate (4) and the forming concave mould (5), the cup cover after being formed can be detached from the concave mould smoothly, thoroughly and quickly, and can not be deformed, so that the production efficiency of the cup cover is improved.
Description
Technical field
The utility model relates to a kind of forming machine of plastics bowl cover, particularly be the demoulding device of plastics bowl cover.
Background technology
At present, because plastic cup is easy to use, and purposes more and more widely, as ice river in Henan Province icepro, fruit juice, milk etc. and can come splendid attire with plastic cup or dixie cup, in order to make the food in the cup avoid dust to spill into, and instant edible all will be provided with a plastics bowl cover on plastic cup.In the prior art, this bowl cover is also finished with a kind of shaped device, this shaped device is made of molding concave die, moulding air blowing mould, on moulding air blowing mould, be provided with valve, valve is aimed at molding concave die, during moulding, after gas blows to molding concave die, make the plastics that heated on the molding concave die picture and text on the molding concave die can be molded over plastic cup and cover.Molding concave die is provided with push rod, and when needing to break away from molding concave die after the bowl cover moulding, push rod along jack-up, makes bowl cover break away from molding concave die in the cup of bowl cover.But, the cup that this push rod withstands bowl cover along the time, all be that an active force acts on cup along last, concerning cup along, it is very uneven rising stressed.And also be in soft condition during owing to the bowl cover moulding, this uneven active force can make bowl cover be out of shape, even becomes waste product, has therefore just reduced the production efficiency of plastics bowl covers.
The utility model content
In view of the deficiency that background technology exists, the technical problems to be solved in the utility model provide a kind of can make when the plastics bowl cover is detached into the type die stressed evenly, can not make the stripper apparatus of the plastics bowl cover of bowl cover distortion.
For this reason, the utility model is realized by the following technical solutions: a kind of stripper apparatus of plastics bowl cover, comprise molding concave die, moulding air blowing mould, described moulding air blowing mould is fixed on the body of plastics bowl cover forming machine, described molding concave die is connected with transmission mechanism, it is characterized in that described molding concave die is provided with the stripper plate that mates with described molding concave die, between described stripper plate and described molding concave die, be provided with elastic device, make described stripper plate not be subjected to external force effect following time can leave described molding concave die; Described elastic device comprises spring, screw, and described molding concave die is provided with the cavity volume that holds described spring, and described spring is placed on the described screw, and described stripper plate is positioned on the described molding concave die by screw; Described molding concave die is connected with described transmission mechanism by centering guide, and described centering guide is provided with tank, and described tank is communicated with paddle hole disposed thereon.
The utility model adopts elastic device, when the demoulding, stripper plate be not subjected to throw off molding concave die under the external force effect, and because stripper plate and molding concave die coupling, the cup of plastics bowl cover is along all contacting with stripper plate, so when stripper plate was thrown off molding concave die, the stripper plate band the cup of bowl cover along leaving molding concave die simultaneously, have stressed evenly, the demoulding is characteristics rapidly.
Description of drawings
Further describe relevant details of the present utility model below more in conjunction with the accompanying drawings.
Fig. 1 is a structure chart of the present utility model;
Fig. 2 is the structure chart of the utility model molding concave die;
Fig. 3 is the cutaway view of Fig. 2 along C-C.
Among the figure, label 1-moulding cover plate, 2-sealing ring, 3-moulding air blowing mould, 4-stripper plate, 5-molding concave die, 6-centering guide, 7-paddle hole, 8-air admission hole, 9-tank, 10-steam vent, 11-cavity volume, 12-spring, 13-screw, 14-air cavity.
The specific embodiment
As shown in the figure, the stripper apparatus of this plastics bowl cover, comprise molding concave die 5, moulding air blowing mould 3, described moulding air blowing mould 3 tops are equipped with moulding cover plate 1, connect by sealing ring 2 between them, form an air cavity 14, and be installed on the body of plastics bowl cover forming machine, described molding concave die 5 is connected with transmission mechanism, described molding concave die 5 is provided with the stripper plate 4 with described molding concave die 5 couplings, between described stripper plate 4 and described molding concave die 5, be provided with elastic device, described elastic device comprises spring 12, screw 13, described molding concave die 5 is provided with the cavity volume 11 that holds described spring 12, and described spring 12 is placed on the described screw 13, and described stripper plate 4 is positioned on the described molding concave die 5 by screw 13; Thereby be not subjected to external force effect following time at described stripper plate 4, because the elastic force of spring 12 makes stripper plate 4 can leave described molding concave die 5; Because during the moulding of plastics bowl cover, the cup of plastics bowl cover is along contact with stripper plate 4, when stripper plate 4 leaves molding concave die 5, is being with the plastics bowl cover to be detached into type die 5, so, the bowl cover of moulding is out of shape.Described molding concave die 5 is connected with described transmission mechanism by centering guide 6, and described centering guide 6 is provided with tank 9, and described tank 9 is communicated with paddle hole 7 disposed thereon.Being provided for of this tank 9 cooled off centering guide 6 and molding concave die 5, avoids molding concave die 5 overheated and damage the bowl cover of moulding.
When the utility model is worked, the plastic sheet that is heated is transported between molding concave die 5 and the moulding air blowing mould 3, molding concave die 5 is owing to the transmission of transmission mechanism is risen, make molding concave die 5 and 3 pressings of moulding air blowing mould, and make stripper plate 4 on the molding concave die 5 be subjected to the pressure of moulding air blowing mould 3 and contact with molding concave die 5, spring 12 is in pressured state, at this moment, gas blows to air cavity 14 by the air admission hole 8 on the moulding air blowing mould 3, and blow into molding concave die 5 by air cavity 14, the plastics of heating are shaped to bowl cover in molding concave die 5, when the bowl cover moulding finishes, molding concave die 5 descends under the transmission of transmission mechanism, when molding concave die 5 descends, because stripper plate 4 is not subjected to the pressure of moulding air blowing mould 3, and the spring 12 of pressurized is in release conditions, thereby just back down stripper plate 4, because the cup of bowl cover is along in the hole that all is enclosed within stripper plate 4 and molding concave die 5 couplings, when stripper plate 4 leaves molding concave die 5, leave molding concave die 5 with bowl cover, finish knockout course, this knockout course, to bowl cover cup edge stressed evenly, so, in the process that breaks away from, can not make the bowl cover distortion, solve existing deficiency in the background technology, had demoulding characteristics rapidly, simultaneously the production efficiency of the bowl cover of Ti Gaoing.
