Description
Technical Field
The invention relates to the field of dust prevention of plastic bottles, in particular to a dust prevention film covering device for a plastic bottle.
Background
The soy sauce bottle is generally made of glass and plastic, the small-bottle soy sauce is generally filled by using a glass bottle, and the large-bottle soy sauce is generally filled by using a plastic bottle.
For plastic soy sauce bottles, after plastic bottles are molded, the plastic bottles need to be transported in batches to soy sauce filling enterprises for filling soy sauce, and finally, the plastic bottles are sealed, so that the bottle mouths of the plastic bottles need to be in an open state in the whole process from molding to filling, dust is easily fed into the bottles, the quality of the soy sauce is affected, and even the health of human bodies is damaged. Therefore, there is an urgent need for a device that can temporarily close the plastic bottle opening to prevent dust from entering the plastic bottle during the whole process from the molding to the filling of the plastic bottle.
Disclosure of Invention
The invention aims to provide a plastic bottle dustproof film covering device which can temporarily seal the opening of a plastic bottle in the whole process from the molding to the filling of the plastic bottle so as to prevent dust from entering the plastic bottle.
In order to achieve the purpose, the invention adopts the following technical scheme:
a dustproof film covering device for plastic bottles comprises a film cutting mechanism and a conveying mechanism positioned below the film cutting mechanism; the membrane cutting mechanism comprises an unwinding roller and a winding roller, a film is wound on the unwinding roller and the winding roller, a moving seat capable of reciprocating is arranged between the unwinding roller and the winding roller, the moving direction and the speed of the moving seat are the same as those of the film, a group of punching cutters which are arranged along the width direction of the film and can vertically reciprocate are arranged on the moving seat, and the punching cutters are tubular; the conveying mechanism comprises an outer conveying belt and an inner conveying belt, the inner conveying belt is positioned on the inner side of the outer conveying belt, the conveying directions and the conveying speeds of the film, the moving seat, the outer conveying belt and the inner conveying belt are the same, a plurality of groups of through holes for the bottle openings of the plastic bottles to penetrate through are formed in the outer conveying belt, and the punching cutter can be inserted into the through holes to cut the film into a film cutting piece and wrap the film cutting piece at the bottle openings of the plastic bottles when moving downwards; the outer side of the feeding end of the inner conveying belt is provided with a material pushing piece used for clamping and pushing plastic bottles, the material pushing direction and speed of the material pushing piece are the same as the conveying direction and speed of the outer conveying belt, an air cavity is arranged in the material pushing piece and communicated with an air exhaust mechanism, and the upper part of the inner side of the material pushing piece is provided with an air inlet.
The principle of the scheme is as follows:
the diaphragm cutting mechanism is used for cutting the film wound on the unwinding roller and the winding roller into a single diaphragm, the conveying mechanism is used for conveying the plastic bottle, the plastic bottle is placed on the inner conveying belt to be conveyed in the conveying mechanism, the bottle opening of the plastic bottle is inserted into the through hole in the outer conveying belt, and the diaphragm is wrapped outside the bottle opening of the plastic bottle when the punching cutter in the diaphragm cutting mechanism moves downwards by inserting the through holes. The film, move the seat, the direction of transfer and the speed homogeneous phase of outer conveyer belt and interior conveyer belt are the same, are in order to guarantee that the plastic bottle keeps static relatively in data send process to guarantee that the film cutting in-process is not dragged, the plastic bottle is by stable conveying, and the diaphragm that cuts down can wrap up outside the bottleneck of plastic bottle.
The material pushing mechanism is used for pushing the plastic bottles to the inner conveying belt and enabling the bottle openings of the plastic bottles to be inserted into the through holes in the outer conveying belt, and meanwhile, the material pushing mechanism can also play a role in clamping the plastic bottles, so that the problem that the plastic bottles are inclined and tilted in the conveying process to cause film covering failure is avoided.
Because the film is cut into the membrane by the punching cutter and covers the membrane on the bottle mouth of the plastic bottle, because the membrane is usually thinner and has certain tensile property, when the punching cutter cuts the membrane, the extrusion force between the notch of the punching cutter and the membrane is larger, the cut membrane is easy to be adhered on the punching cutter and is not easy to fall off from the punching cutter. The purpose of this scheme is and let the diaphragm that cuts come off and firmly adhere in the bottleneck department of plastic bottle from die-cut cutter.
Pushing away the material piece and pushing away the material to the plastic bottle, the in-process of die-cut cutter cutting diaphragm, because it is provided with the inlet port to push away the material piece inboard, bleed through air exhaust mechanism, the air in the bottleneck outside can be siphoned away through the inlet port, consequently can form the negative pressure in the bottleneck outside of diaphragm below, certain adsorption effect has to the diaphragm that cuts off, make the diaphragm drop smoothly from the incision of die-cut cutter, and air exhaust mechanism can be to a certain extent with the intraoral air of the bottleneck of plastic bottle siphoning away a part, the diaphragm parcel is behind the bottleneck of plastic bottle, the inside air of plastic bottle also has certain adsorption effect to the diaphragm, the film is difficult to drop from the bottleneck.
This scheme of adoption can reach following technological effect:
1. through carrying out the tectorial membrane to the bottleneck of plastic bottle, the diaphragm of wrapping up in the bottleneck department of plastic bottle can play dirt-proof effect to the plastic bottle to the film is with low costs, and the plastic bottle that covers the film when needs filling soy sauce, the film is very taken off from the bottleneck department of plastic bottle easily, does not influence follow-up filling soy sauce.
2. During the bottleneck tectorial membrane of plastic bottle, bottleneck department is in the through-hole on the outer conveyer belt, through die-cut cutter from the through-hole in to cutting film down, because the film has certain toughness, outer conveyer belt can play the supporting role to the film, and die-cut cutter cuts the film in the through-hole, cuts off the film more easily.
3. The pushing mechanism has triple functions: firstly, pushing the plastic bottle; secondly, the plastic bottle is clamped, so that the plastic bottle is prevented from tilting; and thirdly, negative pressure can be formed outside the bottle mouth of the plastic bottle through the matching of the air exhaust mechanism, so that the membrane cut by the punching cutter can smoothly fall off from the punching cutter.
