Description

Horizontal and vertical film coating device for cigarette carton pile

Technical Field

The utility model relates to a strip cigarette packing field especially relates to a strip cigarette is piled and is violently indulged diolame device.

Background

At present, one of the known packing machines is used for stacking a plurality of rectangular packing articles such as cigarettes according to a set number, then placing a label on the stacked articles, and then packaging the stack of articles by film sealing. Referring to fig. 1 and 2, the packaging machine comprises a frame 6 ', and a conveying device 1', a counting device 2 ', a stacking device 3', a film covering and sealing device 4 ', a label dispensing device 5' and a turning device 7 'arranged on the frame 6', wherein the conveying device 1 'adopts an upper pinch roller 11' and a lower pinch roller 12 'to clamp and convey strip-shaped articles through a flat belt, the strip-shaped articles are conveyed to the turning device 7', the turning device 7 'rotates a station after receiving a set number of packaged articles to enable the strip-shaped articles to turn downwards to fall on a bearing device of the stacking device 3', the counting device 2 'is arranged at an outlet of the conveying device 1' and is used for counting the strip-shaped articles entering the turning device 7 ', the film covering and sealing device 4' is used for covering a layer of plastic film on the stacked strip-shaped articles and cutting and sealing the plastic film at a joint position of the plastic film, the above-mentioned mechanisms and relative position relationship are clearly described in the patent document published in chinese patent CN2595676, published in 12/31/2003, namely, the patent document disclosed in the automatic film covering and sealing heat-shrink packaging machine with precise guiding mechanism, and will not be described in detail herein.

However, the conventional film sealing apparatus uses a large amount of plastic film, and requires partial cutting, resulting in partial waste. In addition, most importantly, the film covering and sealing device adopts a heat shrinkable film which is a non-degradable plastic film, usually PE film, and although the heat shrinkable film is a stable and reliable packaging material, the heat shrinkable film is discarded for environmental protection unless similar degradable products are used for replacement.

In order to realize reliable and effective environment-friendly packaging, the inventor of the invention carries out long-term research, and correspondingly applies a plurality of patents, such as Chinese patent application numbers: 202120416803.0, a packaging machine with the packaging machine and a packaging machine with the packaging machine, and the Chinese patent application number: 202110410142.5A cigarette carton wrapping, sealing and cutting device and sealing and cutting process thereof, Chinese patent application No.: 202110430548.X relates to a cigarette carton three-dimensional packaging machine and a packaging method thereof. Through various researches, if a conventional degradable winding film is used to replace a heat shrinkable film such as a PLA film, the strength of the heat shrinkable film is difficult to achieve by using one layer of cladding, mainly because the degradable winding film tends to have high brittleness, and the heat shrinkable film has high ductility and high flexibility.

The inventor finds out through corresponding research that a weak part of the degradable winding film usually lies on the seal, and as the toughness of the degradable winding film is far lower than that of the heat shrinkable film and the degradable winding film cannot have better thermal connection performance like the heat shrinkable film, a seal cutting connecting line formed after the degradable winding film is subjected to heat sealing is easy to crack under the condition of impact or stress, and in the field of cigarette carton packaging, the transportation and the transfer are very much, so that the package cannot meet the corresponding packaging requirements and is not suitable for practical use. At present, the packing strength similar to that of the heat shrinkable film can be realized only by adopting a mode of increasing the thickness. The thickness of the existing heat shrinkable film in the field of cigarette carton packaging is about 0.02mm, the heat shrinkable film can meet basic packaging requirements, and if the strength of the corresponding heat shrinkable film is required to be achieved, the thickness of the degradable winding film is 4-5 times that of the degradable winding film, namely the thickness of the degradable winding film is required to be 0.08-0.1 mm. However, the price of the degradable winding film is much higher than that of the heat shrinkable film, and the price rises linearly by adopting the thickness of several times, which causes a great rise in the packaging cost, and there is no corresponding application foundation.

In order to realize the automatic packaging of the degradable winding film by transverse and longitudinal winding, the applicant designs the device.

The lifting driving mechanism, the guiding driving mechanism and the sealing and cutting driving mechanism can be replaced by air cylinders or oil cylinders, electric cylinders and other structures capable of realizing linear displacement reciprocation. The unwinding mechanism is a conventional unwinding roller, the guide mechanism is a guide wheel set formed by one or more guide wheels, and the scheme is realized by adopting three guide wheels. The envelope is made of degradable winding film, namely the PLA film mentioned above, and can also be made of conventional PVC film, and can also be made of conventional materials such as heat shrinkable film and the like. The lifting channel is a virtual concept, and is a space capable of accommodating the cigarette carton pile for lifting. The mechanism can be applied to the coating of one cigarette, but has little significance, and is mainly applied to the coating of a plurality of layers and a plurality of rows of cigarettes.

When the scheme is actually applied, the guide driving mechanism and the sealing and cutting driving mechanism are combined into one mechanism, namely, the coating film is directly approached by pushing of the guide driving mechanism, and bonding and cutting are realized.

An output port 12 'is arranged at the front side of the upper end of the rack 1, a push-out plate 7' for pushing out the cigarettes is arranged on one side, opposite to the output port 12 ', of the rack, and a push-out driving mechanism 71' for driving the push-out plate is arranged on the rack.

Wherein, fig. 4, fig. 5 and fig. 6 constitute a complete process flow, the whole cigarette carton pile can be seen visually in the ascending process, the process comprises the steps of propping against a wrapping film, descending a lifting platform, wrapping the bottom of the cigarette carton pile with the wrapping film, adhering and cutting, and thus, a complete annular wrapping is formed.

The beneficial effects are that:

1. this scheme has changed current cover membrane mode, has realized the function similar with cyclic annular baling press, but cyclic annular packing is really hardly applied to the packing of pile up neatly, because can form thrust to one side of strip cigarette heap during the packing, and because the strip cigarette belongs to lighter product, and has smooth surface, and the strip cigarette will be in disorder immediately under the effect of thrust, causes the result of stamping. This scheme adopts by the mode that leans on of lower supreme top, utilizes lift platform to make the side contact coating film simultaneously on the strip cigarette heap, then utilizes guiding mechanism to realize the coating film to the cladding of strip cigarette both sides limit and bottom, and the cladding is accomplished the back, utilizes again to seal and cuts the mechanism and realize bonding, cut off to a complete cyclic annular cladding has been realized. In addition, the wrapping films are in a slightly tensioned state when being pushed, so that the wrapped cigarette carton pile can be tightly wrapped by the annular wrapping films after wrapping is completed, and a complete package which is not easy to scatter is formed. If want to make the coating film realize compacter, can once more pack along the vertical direction of cyclic annular coating film, form the cross packing, or can adopt the coating film of heat shrink to carry out the cladding, perhaps utilize cyclic annular baling press to carry out a cross packing.

This scheme utilizes a stable structure, has not only realized the simple and convenient on the flow, has also improved work efficiency greatly, and it is compared current covering film and sealed the packing, and packing time has saved about one time.

2. The arrangement of the output port, the push-out plate and the push-out mechanism can realize automatic output, and moreover, the stability of the cigarettes can be realized by the cooperation of the push-out plate and the bearing plate. When the supporting plate is moved in to support the cigarette carton and the lifting platform does not descend, the push-out plate can stretch out simultaneously, the cigarette carton can be leveled and pushed against one side, and after the lifting platform descends, the push-out plate can be supported in a matched mode with the supporting plate. In addition, the lower extreme department of ejector plate is equipped with the supporting platform who is used for realizing the support to the strip cigarette, and the ejector plate can form an "L" shaped plate like this in fact to can cooperate the backup pad to realize better bearing. The take-off roller mechanism may facilitate take-off. The displacement limiting mechanism is arranged to realize that when the pushing driving mechanism drives the pushing, physical limitation exists to avoid excessive pushing, and the mechanism can be realized by directly limiting the stroke of the pushing driving mechanism without being arranged.

3. The sealing and cutting mechanism can realize the purposes of forming an annular coating film, bonding the coating films of the two unwinding mechanisms and cutting. Due to the specific arrangement of the mechanism, cutting and bonding can be effectively realized, and the efficiency is high. The lower sewing part and the upper sewing part can have the same structure, and the upper sewing part is arranged, so that the purpose of bonding can be effectively realized.

A cigarette carton wrapping, sealing and cutting process comprises the following steps:

firstly, forming a horizontally placed coating film by using a unreeling mechanism;

secondly, inputting the strip cigarette stack to a lifting platform, wherein the strip cigarette stack is provided with a longitudinal direction along the length direction of the strip cigarettes and a transverse direction along the width direction of the strip cigarettes, and the lifting platform is used for lifting the strip cigarette stack, so that the transverse direction of the strip cigarette stack is consistent with the length direction of the coating film, and the upper surface of the strip cigarette stack is partially or completely coated by the coating film;

thirdly, supporting the cigarette carton pile by using a supporting plate, and resetting a lifting platform to realize the conversion of the support;

fourthly, pushing the coating films on the two sides of the strip cigarette stack in the transverse direction to the lower part of the strip cigarette stack and the middle part of the strip cigarette stack so that the coating films on the two sides of the strip cigarette stack in the transverse direction are close to each other in the middle part of the lower part of the strip cigarette stack;

fifthly, sewing and cutting off the mutually close wrapping films at the middle part below the cigarette carton pile to realize seal cutting, so that an annular wrapping film is formed outside the cigarette carton pile;

and sixthly, outputting the cigarette carton stack.

In the third step, when the bearing plate is positioned at one side of the cigarette carton, the bearing is realized by the cooperation of the pushing plate; when the bearing plates are positioned at two sides of the cigarette carton, namely the bearing plates are positioned at two sides of the lifting platform in the horizontal direction, the push-out plate only realizes the purpose of pushing out.

The method is different from the method for wrapping the cigarette carton pile in the field, so that the working efficiency is effectively improved, and the whole packaging process is smoother.
