Abstract

The plastic film mechanical-packaging process is characterized by that firstly, adopting existent technological process to cover packaging box exterior with plastic film, then feeding the packaging box whose exteror is covered with plastic film into a special-made heat transfer baking body to heat it and shrink to make the plastic film close stick on the packaging box, and said plastic film surface is smooth and level, has no goffer, so that said process is applicable to packaging cigarettes, carton of cigarettes, boxed food, beverage and drug, etc..

Description

Plastic film mechanical packing technology

The invention belongs to a kind of packing technology, particularly the packing box outside to cigarette case, plume, boxed food, beverage, medicine etc. coats one deck plastic film, and makes the tight attached work of plastic film in the new process on packing box surface.

At present; outside the packing box of cigarette case, plume, generally all be coated with one deck plastic film; also there is plastic film in the packing box outside at part boxed food, beverage, medicine etc.; the purpose that plastic film is set generally is in order to protect content; simultaneously also the attractive in appearance of packing be can promote, the raising and the sale of product specification helped.Yet, the plastic film that utilizes existing process to coat, because the shortcoming of its process, usually with packing box between combine and seem loose, wrinkle Zhe appears easily, thereby its aesthetics is greatly affected, cause the low bad impression of product specification to the customer, the sale of product is brought adverse effect, for improveing this phenomenon, at present to the class high product, generally all select quality plastic film material preferably for use, can make moderate progress though do like this, but still can not tackle the problem at its root, and because higher to the material requirement of plastic film material, from and improved the cost of packing.

The objective of the invention is at the existing above-mentioned deficiency of plastic film packing technology it be improved, so that under the situation of using common material plastic film, the attached work of plastic film that is coated and packing box is tight, smooth in appearance is smooth, does not give birth to wrinkle Zhe.

Major technique measure of the present invention is as follows:

A kind of plastic film mechanical packing technology is to improve to form on the basis of existing plastic film mechanical packing process, and its main processes is as follows:

At first adopt existing process outside packing box, to coat plastic film, and then it is sent into a purpose made conduct heat to add and iron in the body, plastic film adds to iron in the body in this heat transfer and is heated, because of plastic film has thermal pinch, thereby thermal contraction reaction promptly takes place after being heated and closely attached work on packing box, add to iron in the body by heat transfer at last and send.The plastic film of packing box adds the heated time and the heat transfer of ironing in the body in heat transfer and adds the temperature relation of being inversely proportional in the body that irons, and becomes certain relation with the material of plastic film, therefore needs according to material, conducts heat to add and iron body length and the equipment situation is regulated flexibly.

The plastic film that coats with the inventive method, to the plastic film material require low, the attached work of plastic film closely, performance smooth smooth, do not produce wrinkle Zhe, thereby both can reduce the packing productive costs, the sale to product has facilitation preferably again.

Below in conjunction with accompanying drawing and the embodiment that provides thereof the present invention is further described:

Fig. 1 is that the packing box plastic film adds in heat transfer and irons the situation scheme drawing that is heated in the body;

Fig. 2 conducts heat to add to iron the body structure scheme drawing.

The present invention is a kind of plastic film mechanical packing technology, and it is to improve to form on the basis of existing plastic film mechanical packing process, and its main processes is as follows:

At first adopt existing process outside packing box, to coat plastic film, and then it is sent into a purpose made conduct heat to add and iron in the body 1, plastic film heat transfer add that ironing is heated in the body 1 thermal pinch take place and closely attached work on packing box, sends at last from conducting heat to add to iron in the body 1.

Wherein conduct heat and add the structure that irons body 1 and see also shown in Figure 2, it mainly is made up of the cuboid body 11 that thermal conductive metallic material is made, at cuboid body 11 internal recessings 12, be embedded in electric heating element 13 at groove 12, and adopt temperature-sensing element 14 and temperature controller 15 control electric heating elements 13; And adopt two identical heat transfers to add to iron body 1 be arranged at packing box 2 delivery tracks upper and lower sides or about face, as shown in Figure 1.

The present invention now uses on YB54, YB52 type cigarette plastic film wrapping machine, it is 168mm that its heat transfer adds the length that irons body 1, wide 86mm, adopt platinum resistance as temperature-sensing element 14, two heat transfers add irons the upper and lower sides that body 1 is arranged at the cigarette delivery track, heat transfer adds the temperature that irons body 1 and is controlled at 155 ℃-160 ℃, all other all do not do any change to equipment, through one section long period test, prove that process of the present invention is simple and feasible, it is tight to coat the attached work of plastic film, and smooth surface is smooth, and the plastic film material is not had specific (special) requirements.

Claims

1, a kind of plastic film mechanical packing technology, be on the basis of existing plastic film mechanical packing technology, to improve to form, it is characterized in that: its technological process is, at first adopt existing process outside packing box, to coat plastic film, and then it is sent into a purpose made conduct heat to add and iron in the body [1], plastic film this heat transfer add that ironing is heated in the body [1] thermal pinch take place and closely attached work on packing box, add to iron in the body [1] by heat transfer at last and send.

2, plastic film mechanical packing technology according to claim 1, it is characterized in that: described heat transfer adds irons body [1] and makes cuboid body [11] by thermal conductive metallic material, at cuboid body [11] internal recessing [12], be embedded in electric heating element [13] at groove [12], and adopt temperature-sensing element [14] and temperature controller [15] control electric heating element [13]; And adopt two identical heat transfers to add to iron body [1] be arranged at packing box [2] delivery track upper and lower sides or about face.
