Detailed implementation manners

[0020] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and in no way limits the present disclosure and its application or use. The present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the present disclosure thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, the components of materials, numerical expressions and values set forth in these embodiments should be construed as merely exemplary and not as limitations.

[0021] The "first", "second", and similar terms used in the present disclosure do not denote any order, quantity, or importance, but are only used to distinguish different parts. Terms such as "comprising" or "including" mean that the elements before the term cover the elements listed after the term, and do not exclude the possibility of also covering other elements. Terms such as "upper" and "lower" are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0022] In the present disclosure, when it is described that a specific component is located between a first component and a second component, there may or may not be an intermediate component between the specific component and the first component or the second component. When it is described that a specific component is connected to other components, the specific component may be directly connected to the other components without an intermediate component, or may not be directly connected to the other components but have an intermediate component.

[0023] All terms used in the present disclosure (including technical terms or scientific terms) have the same meaning as understood by those of ordinary skill in the art to which the present disclosure pertains, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary such as should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such herein.

[0024] Techniques, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods, and devices should be regarded as part of the specification.

[0025] Some cigarette brands require the overlap width of the carton transparent paper to be 35 mm and the overlap to be centered. Therefore, during the folding process of the long side of the carton transparent paper, the lengths of the first folded edge and the second folded edge of the carton transparent paper are quite the same, resulting in the situation that the two side edges of the transparent paper interfere with each other during the folding process. This will directly cause the second folded edge of the cigarette strip to be folded first, resulting in situations such as reverse folding and wrinkling of the long side overlap on the appearance of the cigarette strip, which not only affects the appearance quality of the cigarette strip, but also affects the subsequent folding of the short side of the cigarette strip and the subsequent production process. Therefore, the existing CV carton transparent paper folder is only applicable to the folding of carton transparent paper with a narrow overlap and the overlap biased to one side; moreover, the cam curves of the long side folder and the short side folder of the carton transparent paper cannot meet the folding requirements.

[0026] As Figure 1 and Figure 2 shown, the CV carton transparent paper wide overlap centered folding device provided in this embodiment includes: a first lifting channel 8 for the cigarette strip 2 to pass through from bottom to top. The first lifting channel 8 is composed of a front plate 9 and a rear plate 10 arranged opposite to each other. A negative pressure pipe 5 is connected to the rear plate 10. The negative pressure pipe 5 is used to convey negative pressure to suck the second folded edge of the pre-folded carton transparent paper through negative pressure. A negative pressure adjustment structure 4 is provided on the negative pressure pipe 5, and the negative pressure adjustment structure 4 is used to adjust the magnitude of the negative pressure.

[0027] Among them, the negative pressure adjustment structure 4 includes a throttle valve.

[0028] Further, as Figure 2 shown, the CV carton transparent paper wide overlap centered folding device further includes a negative pressure conveying channel connected to the negative pressure adjustment structure 4.

[0029] Further, a negative pressure suction port (not shown) is opened on the rear plate 10, and the negative pressure pipe 5 is connected to the rear plate 10 through the negative pressure suction port.

[0030] Among them, the number of the negative pressure suction ports is two. Correspondingly, the number of the negative pressure pipes 5 is two, which are respectively connected to the two negative pressure suction ports. It should be noted that the present invention does not limit the number and distribution positions of the negative pressure suction ports and the negative pressure pipes 5.

[0031] Further, the CV carton transparent paper wide overlap centered folding device further includes a carton transparent paper short side folder 6, which is used to push forward into the carton channel 1 when the negative pressure pipe 5 sucks the second folded edge 3 of the pre-folded carton transparent paper through negative pressure, so as to fold the first folded edge 7 of the carton transparent paper.

[0032] Further, the CV strip carton transparent paper wide lap center folding device further includes a strip carton transparent paper long side folder (not shown), which is used to push the cigarette strip 2 into the strip carton channel 1 after the first fold 7 of the strip carton transparent paper is completed, and at the same time complete the folding of the rear fold 3 of the strip carton transparent paper.

[0033] Further, the CV strip carton transparent paper wide lap center folding device further includes a lifter (not shown), which is used to lift the cigarette strip 2 covered with transparent paper from the bottom to a position flush with the strip carton channel 1 through the first lifting channel 8.

[0034] During operation, when the folding of the strip carton transparent paper reaches the Figure 1 shown working station, the negative pressure of the negative pressure pipe is used to suck the rear fold 3 of the pre-folded strip carton transparent paper, and the short side folder 6 of the strip carton transparent paper advances towards the strip carton channel 1 to fold the first fold 7 of the strip carton transparent paper; after the first fold is completed, the cigarette strip is pushed into the strip carton channel 1 by the long side folder of the strip carton transparent paper, and at the same time the folding of the rear fold 3 of the strip carton transparent paper is completed; the magnitude of the negative pressure can be adjusted through the negative pressure adjustment structure 4.

[0035] The CV strip carton transparent paper wide lap center folding device provided by the embodiment of the present invention uses the negative pressure of the negative pressure pipe to adsorb the rear fold of the strip carton transparent paper, so as to fix one side of the strip carton transparent paper by the method of negative pressure adsorption, and uses the negative pressure adjustment structure to control the magnitude of the negative pressure, so that the strip carton transparent paper can be better fixed, thereby making the appearance of the packaged strip carton more perfect, solving the problem that the two sides of the long side interfere with each other during the folding of the wide lap strip carton transparent paper, improving the product quality, and enhancing the production efficiency of the equipment; the solution is simple and feasible, avoiding the cumbersome process of changing the cam curve of the long side folder and the complex process of changing the cam curve of the short side folder; the present invention solves the adaptability problem of the strip carton transparent paper folder to the wide lap center strip carton transparent paper, and is also applicable to the packaging of the narrow lap non-centered strip carton transparent paper.
