Description

Technical Field

[0001] The present invention relates to the technical field of cigarette production, in particular to a plastic sealing beautification method. Background Art

[0002] Transparent paper packaging for cigarette packs not only ensures product quality and facilitates portability and transportation, but also serves as a promotional tool. Transparent paper is typically made of BOPP (Biaxially Oriented Polypropylene) cigarette film. Wrapping the pack snugly, smoothly, and wrinkle-free creates a more aesthetically pleasing appearance, enhancing brand reputation and increasing consumer purchasing power.

[0003] In the prior art, after transparent paper is wrapped around the cigarette pack, an electric soldering iron is often used to iron the pack. Regardless of whether the iron is applied to two, four or six sides, the high-speed reciprocating motion of the soldering iron is difficult to control and can easily damage and wear the cigarette pack. Repeated ironing can easily cause the transparent paper on the edges and eight corners of the pack to be burned through, reducing the production efficiency of the entire cigarette production line.

[0004] Based on the above, a plastic sealing beauty method is urgently needed to solve the above technical problems. Summary of the Invention

[0005] The object of the present invention is to provide a plastic sealing beautification method, which can make the transparent paper packaging of cigarette strips smooth, flat and wrinkle-free, and has high beautification efficiency and high yield rate.

[0008] S1. Transporting the strip bag along a preset conveying direction and blowing air to heat the first end surface, the front surface, the first side surface, and the second side surface for beauty treatment, wherein the preset conveying direction is perpendicular to the first end surface, and the first end surface is located in front of the second end surface;

[0009] S2, turning the strip pack over so that the strip pack faces from the front side upward to the back side upward;

[0010] S3, blowing air to heat the back surface for beauty treatment;

[0011] S4, blowing air to heat the second end surface, the back surface, the first side surface and the second side surface for beauty treatment.

[0012] Preferably, in step S1 , while the first end surface, the front surface, the first side surface and the second side surface are subjected to air blowing heating, the second end surface and the back surface are preheated.

[0013] Preferably, in step S1, when performing air blowing heating, a first airflow with a temperature of 110 degrees Celsius to 130 degrees Celsius is used.

[0014] Preferably, in step S1 , the blowing direction of the first airflow and the preset conveying direction have an angle of 120 degrees to 135 degrees.

[0015] Preferably, in step S1 , the output pressure of the first airflow is 1.5 atmospheres.

[0016] Preferably, in step S1, air blowing heating is performed when the strip pack moves over a distance that is three times its own length.

[0017] Preferably, in step S3, when performing air blowing heating, a second air flow with a temperature of 130 degrees Celsius to 150 degrees Celsius is used.

[0018] Preferably, in step S3, the blowing direction of the second airflow is perpendicular to the back surface.

[0019] Preferably, in step S4, when performing air blowing heating, a third air flow with a temperature of 110 degrees Celsius to 130 degrees Celsius is used.

[0037] The following is based on the attached Figure 1 To the attached Figure 8 The present invention provides a method for plastic sealing beauty. Figure 1 、 Figure 2 As shown, in the present invention, the six surfaces of the strip package are defined as the front side 1, the back side 7, the first end side 3, the second end side 9, the first side 2, and the second side 8. The front side 1 and the back side 7 are arranged opposite each other, and the front side 1 and the back side 7 are surfaces along the length and width of the strip package, and the back side 7 is provided with an overlap structure 5. The first end side 3 and the second end side 9 are arranged opposite each other, and the first end side 3 and the second end side 9 are surfaces along the width and thickness of the strip package, connected between the front side 1 and the back side 7, and the first end side 3 and the second end side 9 have an overlapping structure 10. The first side 2 and the second side 8 are arranged opposite each other, and the first side 2 and the second side 8 are surfaces along the length and thickness of the strip package, connected between the front side 1 and the back side 7, and connected between the first end side 3 and the second end side 9. A pull cord 4 is provided around the front side 1, the first side 2, the back side 7, and the second side 8, and a pull cord head 6 is provided on the back side 7.

[0038] In the present invention, the beautification of the bag mainly includes four steps. Specifically including:

[0039] Step S1: transport the strip bag along a preset conveying direction, and blow air to heat the first end face 3, the front face 1, the first side face 2 and the second side face 8 for beauty treatment. The preset conveying direction is perpendicular to the first end face 3, and the first end face 3 is located in front of the second end face 9.

[0040] Specifically, in step S1, the strip pack is transported along a preset conveying direction (eg Figure 4 The back side 7 of the stick pack is placed on the conveyor belt, and along the predetermined conveying direction, the first end face 3 of the stick pack is located in front of the second end face 9. The conveyor belt is formed with multiple synchronous conveying sections that can abut against the second end face 9, thereby conveying the stick packs one by one in an orderly manner.

[0041] During transportation along the preset conveying direction, the first end surface 3 is perpendicular to the preset conveying direction. At this time, the first end surface 3, the front surface 1, the first side surface 2 and the second side surface 8 can be blown and heated for beauty treatment, so that they shrink due to the heat, thereby eliminating wrinkles.

[0042] Step S2: Turn the strip pack over so that the front side 1 of the strip pack faces upward and the back side 7 of the strip pack faces upward.

[0043] Specifically, in step S2, the flipping can be performed by a manipulator or a dedicated flipping mechanism 104. There are many structures in the prior art that can achieve flipping, which will not be described in detail in the present invention.

[0044] Step S3: Blowing air to heat the back surface 7 for beauty treatment.

[0045] Specifically, in step S3, by blowing air to heat the back surface 7, it is possible to ensure that the wrinkles at the overlap structure 5 of the transparent paper are completely heated and shaped. Figure 2 As shown, since the back side 7 is provided with the overlap structure 5, the back side 7 is the side with the largest wrinkle area and the most serious folds on the bag, and is the key part that needs plastic surgery.

[0046] Step S4: Blowing air to heat the second end surface 9, the back surface 7, the first side surface 2 and the second side surface 8 for beauty treatment.

[0047] Specifically, in step S4, by blowing air and heating the second end surface 9, the overlapping structure 10 on the second end surface 9 can be heated and reshaped to achieve the purpose of beauty. In addition, by blowing air and heating the back surface 7, the first side surface 2, and the second side surface 8 again, the achieved beauty effect can be optimized.

[0048] Through the above-mentioned plastic sealing beauty method, heating is performed by blowing air, which can heat and shape all surfaces, edges and corners of the strip bag to achieve all-round beauty without dead angles. At the same time, compared with a soldering iron, it can avoid pressure damage and excessive burns to the strip bag, and also avoid excessive temperature differences between different surfaces of the strip bag, which makes it difficult to achieve better beauty effects.

[0049] More specifically, in step S1, while the first end surface 3, the front surface 1, the first side surface 2, and the second side surface 8 are being heated by air blowing, the second end surface 9 and the back surface 7 are also preheated. By preheating the second end surface 9 and the back surface 7 in step S1, it is possible to provide good heating conditions for the cosmetic treatment of the overlap structure 5 and other areas prone to wrinkling in step S3, thereby avoiding the formation of dead wrinkles on the back surface 7 due to excessive heating in step S3, which may lead to appearance defects.

[0050] For example, in step S1, during the air blowing heating, a first airflow with a temperature of 110 to 130 degrees Celsius is used. The first airflow can form an environment with a certain temperature around the strip pack, thereby achieving a preheating effect.

[0051] Specifically, if Figure 7 As shown, in the present invention, a plastic-sealed beauty device is provided, which includes a first section 101, a second section 102, and a third section 103. When the strip package is transported through the first section 101, the second section 102, and the third section 103, steps S1, S3, and S4 are respectively implemented. A turning mechanism 104 is provided between the first section 101 and the second section 102, which can implement the above-mentioned step S2. Among them, the first section 101 is provided with a wind tunnel structure 105, and the conveyor belt can transport the strip package through the wind tunnel structure 105. Figure 8 As shown, a soldering iron structure 106 is disposed within the wind tunnel structure 105. The soldering iron structure 106 is semicircular and uniformly provided with multiple air inlet holes 107. When air is driven by pressure through the air inlet holes 107, it is heated to a corresponding temperature and forms the aforementioned first airflow, which then flows toward the first end surface 3, the front surface 1, the first side surface 2, and the second side surface 8, thereby applying air-blowing heating. This facilitates the creation of the aforementioned temperature environment within the wind tunnel structure 105, thereby preheating the rear surface 7.

[0052] Furthermore, if Figure 4 As shown, in step S1, the blowing direction of the first airflow is set at an angle α of 120 degrees to 135 degrees with the preset conveying direction (as shown in FIG. Figure 4(Indicated by arrow A in the middle). This blowing direction simultaneously heats the first end surface 3, the front surface 1, the first side surface 2, and the second side surface 8. Furthermore, the airflow pressure can be used to hold the stick package tightly against the conveyor belt, allowing the stick package to enter the turning mechanism in a precise and stable position. For example, in this embodiment, the output pressure of the first airflow is 1.5 atmospheres.

[0053] Optionally, in this embodiment, the length S of the first section 101 is 3 times the length L of the tobacco pack itself, that is, in step S1, when the tobacco pack moves over a distance 3 times its own length L, it is blown and heated to prevent the tobacco pack from being overheated for a long time.

[0054] It should be noted that during the heat-sealing process of the transparent paper wrapping, the front side 1 is far away from the shadow of the heat seal and has the least wrinkles. It is the most beautiful and brightest of the six sides. Therefore, it is only heated in step S1, and the strip package is turned 180° in step S2 so that the front side 1 is in contact with the conveyor belt. In this way, the front side 1 is kept warm in the remaining steps to prevent it from being overheated and causing dead wrinkles.

[0055] Furthermore, in step S3, a second airflow with a temperature of 130 to 150 degrees Celsius is used to heat the back side 7 of the strip pack. After preheating, the second airflow with a temperature higher than the first airflow can be used to beautify the back side 7 with more wrinkles, thereby avoiding the formation of dead wrinkles caused by excessive heating and achieving a better beautification effect. For example, Figure 5 As shown, the blowing direction of the second airflow is perpendicular to the back surface 7, that is, blowing from top to bottom toward the back surface 7 (as shown in FIG. Figure 5 The arrangement of the angle β with the preset conveying direction is 90°, as shown by the middle arrow B, so that the back surface 7, especially the overlap structure 5, can be subjected to better cosmetic treatment.

[0056] In step S4, when performing air blowing heating, a third air flow with a temperature of 110 degrees Celsius to 130 degrees Celsius is used. Figure 6 As shown, the blowing direction of the third airflow is set at an angle γ of 45 to 60 degrees with the preset conveying direction (as shown in FIG. Figure 6 Of course, in some embodiments, the third airflow can also be used to blow and heat the remaining back surface 7, the first side surface 2 and the second side surface 8, thereby achieving tempering treatment.

[0057] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
