Description

Technical Field

[0001] The present invention relates to the technical field of cigarette rod side sealing, and more particularly to a method for ironing transparent paper for cigarette rod side sealing of a ZB417D packaging machine. Background Art

[0002] Due to design defects, the YB95 prefabricated strip box transparent paper packaging machine of the ZB417D packaging unit has problems such as poor heat sealing on both ends of the strip box. Through observation and research on the soldering iron sealing method and material structure characteristics, it is concluded that the design of the soldering iron working surface is unreasonable and cannot perfectly fit the prefabricated strip box. Figure 1 .

[0003] The ZB417D is a new model that has emerged in recent years. It produces full-clamshell cigarette packs and stand-up stick packs, a significant departure from the traditional standard packaging method. It consists of four components: the YB417D preformed small box packaging machine, the YB55 small pack transparent paper packaging machine, the YB613 preformed stick box packaging machine, and the YB95 stick pack transparent paper packaging machine. This change in packaging method has led to various new problems and malfunctions.

[0004] The mechanical structure of heat sealing iron is relatively simple. Figure 2 Its function is to heat it to a certain temperature so that the working surface can completely fit the end face of the box, and seal the transparent paper that has been folded into place on it, so that it can be pasted flatly, firmly and beautifully.

[0005] Due to the use of prefabricated boxes, see Figure 3 The middle plane of the two end faces is lower than the surrounding surface, forming a groove. This makes it impossible to use a soldering iron with an area larger than the two end faces. In addition, the prefabricated strips are made of cardboard, which is relatively hard. When the transparent paper is sealed with iron, the center of the carton is forced inward, and the transparent paper edges are not compacted. This will cause quality problems such as wrinkling, melting, hardening, and loose adhesion. Specifically, at a soldering iron temperature of 150°C, the outer circle is sealed normally, but the center is not compacted, and the transparent paper buckle opens. Increasing the temperature to above 160°C will cause the transparent paper edges to melt, harden, and break, and the buckle opening phenomenon does not improve. Summary of the Invention

[0036] The following will be combined Figure 4-Figure 5 , a ZB417D packaging machine cigarette side seal transparent paper ironing structure involved in the embodiment of the present application is described in detail. It is worth noting that the following embodiments are only used to explain the present application and do not constitute a limitation of the present application.

[0037] Embodiment 1:

[0038] like Figure 4-5 As shown, a method for ironing the transparent paper sealing the cigarette rod side of a ZB417D packaging machine is implemented based on the ironing structure of the transparent paper sealing the cigarette rod side of the ZB417D packaging machine, and specifically includes the following steps:

[0039] Step 1: Preheat the soldering iron base so that the temperature of the heat conduction unit is heated to a preset temperature; the preset temperature is 150°C-155°C.

[0040] Step 2: Move the heat conducting units of the soldering iron bases on both sides toward the grooves at both ends of the cigarette box to seal the transparent paper. Usually, the sealing time of the transparent paper is 1s-3s.

[0041] In some embodiments, the cross section of the heat conducting unit is coaxially arranged with the groove at the end of the cigarette box, and the area ratio of the cross section of the heat conducting unit to the groove surface at the end of the cigarette box is: (0.7-0.9):1.

[0042] The ZB417D packaging machine's transparent paper ironing mechanism for side-sealing cigarette strips in the aforementioned method comprises a soldering iron base and a heat-conducting unit. The soldering iron base provides a heat source for the heat-conducting unit. The heat-conducting unit is mounted on the working surface of the soldering iron base and exhibits certain compressibility and ductility. The heat-conducting unit's area is smaller than the area of ​​the grooves at the ends of the cigarette pack, and its thickness is greater than the thickness of the grooves at the ends of the cigarette pack. The heat-conducting unit comprises a thermally conductive silicone sheet 7, high-temperature adhesive tape 1, and a pressure plate 2. The thermally conductive silicone sheet 7 is mounted on a heating platform 6 via the high-temperature adhesive tape 1, and the pressure plate 2 is used to press the high-temperature adhesive tape 1.

[0043] In some embodiments, the soldering iron base includes a first soldering iron body 3 and a second soldering iron body 4. A thermocouple 5 is disposed between the first and second soldering iron bodies 3 and 4. A protruding heating platform 6 is provided on the working surface of the first soldering iron body 3. The heat transfer unit is fixed to the heating platform 6. The first and second soldering iron bodies 3 and 4 have grooves on opposing sides for securing the thermocouple 5. Heat generated by the thermocouple 5 is transferred to the heating platform 6 and then to the thermally conductive silicone sheet 7.

[0044] To ensure a beautiful and secure fit on the strip of transparent paper, the curved depression in its center must be filled. The original soldering iron's flat metal work surface was difficult to convert to a curved surface, and the dimensions of the prefabricated strips varied, making it difficult to control. Therefore, the inventors modified the soldering iron's work surface into a soft surface, allowing it to perfectly fit the two ends of the prefabricated strip, sealing and compacting the transparent paper.

[0045] To address this issue, the soldering iron's working surface was redesigned, changing from a hard surface to a soft surface, creating a soft soldering iron. To ensure heat sealing of the transparent paper, the working surface had to fit perfectly against the two ends of the prefabricated box, reducing the working surface to a suitable size. Using an angle grinder, the edges of the working surface were removed, leaving a central heating plate (6) measuring 40 mm x 68 mm.

[0046] A thermally conductive silicone sheet 7 of corresponding size is placed on the modified heating platform 6, and high-temperature tape 1 is affixed on the thermally conductive silicone sheet 7 to cover the entire soldering iron surface. Two upper and lower stainless steel strips are placed on the periphery to fix the high-temperature tape 1 to prevent the high-temperature tape and the thermally conductive silicone sheet 7 from shifting. This transforms the original soldering iron into a soft soldering iron.

[0047] The soft soldering iron in this application refers to a soldering iron whose working part is soft, has a certain degree of compression and ductility when the soldering iron is pressed, and returns to its original shape after being opened.

[0048] In some embodiments, the thermally conductive silicone sheet 7 is a 3M high-thermal conductive silicone sheet 7 with a thickness of 1.5-2 mm, a temperature resistance range of -40°C to 220°C, a hardness of 30-40 Shore C, and a thermal conductivity of 4.0 W / mK. With these parameters, the thermally conductive silicone sheet 7 has good compression properties and can fully fill the gap between the soldering iron and the prefabricated strip box.

[0049] In some embodiments, the high-temperature tape 1 provides fixation and protection, as well as anti-adhesion and wear resistance for the work surface. Domestically produced Teflon high-temperature tape 1 is used, with a thickness of 0.13 mm and a temperature resistance range of -70°C to 230°C. The Teflon high-temperature tape 1 has a glass fiber surface, which provides excellent wear resistance and anti-stick properties.

[0050] After the transformation, through long-term operation and observation, the quality defect of loose heat sealing on both end surfaces of the strip box was perfectly solved.

[0051] The invention of the YB95 prefabricated box heat-sealing soldering iron device solved the quality problem of the YB95 prefabricated box transparent paper not being firmly heat-sealed. At the same time, it established new maintenance standards for the soldering iron and accumulated valuable experience for filling the gaps in high-temperature environments.

[0052] This device is simple, practical and low-cost. At the same time, it is easy to disassemble, install and replace, thus saving costs as much as possible.

[0053] The soft soldering iron can perfectly fit and compact the prefabricated strip box when sealing the transparent paper. Thus, the problem of loose heat sealing is solved and the product quality is improved.

[0054] The cigarette rod side sealing iron device developed using this method can iron the sides of the cigarette rods very well, avoiding the situation where the sides of the cigarette rods are not ironed properly, effectively preventing unqualified products from flowing into the next process, and effectively reducing the quality risk of the product.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
