[0049] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0050] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0051] In the description of this utility model, "several" refers to one or more, and "multiple" refers to two or more. The use of "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, the number of indicated technical features, or the sequential relationship between indicated technical features.
[0052] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0053] In related technologies, after the product packaging film is processed into a cylindrical shape, it is first folded at one corner, and then folded at another corner so that the second corner can cover and press down on the first corner. Finally, the hot-sealing mechanism hot-seals at the second corner position, so that the overlapping position of the first and second corners is hot-sealed as one piece. However, during the production process, the equipment needs to be adjusted multiple times to ensure that the first corner can be directly covered and squeezed by the second corner. Otherwise, the first corner may not be covered by the two corners, resulting in poor hot sealing of the product packaging film.
[0054] Reference Figures 1 to 3 As shown, the first aspect of this utility model provides a hot-seal forming mechanism for sealing the outer transparent film of a product 10, such as the outer transparent film of a cigarette or the outer transparent film of a gift box. The hot-seal forming mechanism includes: a first conveyor line 100, two corner plates 200, and two first hot-pressing components 300.
[0055] The first conveyor line 100 is capable of conveying product 10 along a first direction.
[0056] Specifically, the first conveyor line 100 can be a conveying mechanism such as a belt conveyor or a roller conveyor. The upper surface of the first conveyor line 100 is a bearing surface, which is generally horizontal to stably place the product 10. When the first conveyor line 100 is working, the bearing surface is moved relative to the ground in a first direction to move the product 10 on the bearing surface relative to the ground in the first direction. The conveying method of the first conveyor line 100 is intermittent, that is, after conveying for a certain period of time, it is paused for a period of time, and then the conveying process and the pause process are alternated. The reason why the first conveyor line 100 needs to pause is that during the hot-sealing process of the packaging film 20 of the product 10, it needs to remain relatively stationary with the first hot-pressing component 300 so that the first hot-pressing component 300 can stably and continuously hot-press the packaging film 20 outside the product 10, thereby making the packaging film 20 hot-sealed as a whole.
[0057] Two folding plates 200 are arranged opposite each other along a second direction. The two folding plates 200 are located on both sides of the first conveyor line 100 along the first direction and are used to fold the two ends of the packaging film 20 of the product 10 along the second direction. The opposite surfaces of the folding plates 200 are provided with heat-pressing holes 201. The second direction is perpendicular to the first direction. Generally, the second direction is also a horizontal direction and is in the horizontal plane along with the first direction.
[0058] It should be noted that the packaging film 20, which is folded by the corner plate 200, is cylindrical, generally rectangular, and both ends of the rectangular tube extend outwards from the product 10 along the second direction. The extended portion of the rectangular tube includes an upper half and a lower half. The corner plate 200 mainly folds the upper half, making it fit snugly against the end face of the product 10.
[0059] Specifically, the corner folding plate 200 folds the upper part of the packaging film 20 by guiding the movement of the packaging film 20, and two corner folding plates 200 can simultaneously fold opposite ends of the product 10, improving work efficiency. After folding, the corner folding plate 200 can still limit the position of the packaging film 20 of the product 10 after folding.
[0060] Two first hot-pressing components 300 are arranged opposite each other along the second direction. The two first hot-pressing components 300 are arranged opposite each other on both sides of the first conveyor line 100 along the first direction and are used to heat-seal the two end faces of the corner of the product 10 along the second direction. The first hot-pressing component 300 has a first hot-pressing part 310, which passes through the hot-pressing hole 201 and has a first hot-pressing surface for hot-pressing the packaging film 20 of the product 10.
[0061] Specifically, after the corner plate 200 is folded, the first hot pressing assembly 300 drives the first hot pressing part 310 to move along the second direction, so that the first hot pressing part 310 passes through the hot pressing hole 201, and the first hot pressing surface abuts the upper half of the packaging film 20 against the end face of the product 10. At the same time, the first hot pressing surface performs heat sealing, so that the upper half and the overlapping part of the packaging film 20 along the first direction are heat sealed together, realizing the temporary fixation of the upper half, so that the upper half cannot be reset again in the subsequent processing, which greatly reduces the occurrence of poor heat sealing of the packaging film 20 due to the upper half being reset, which is conducive to improving the yield and production efficiency.
[0062] It is worth understanding that by combining the first hot-pressing component 300 with the corner folding plate 200, after the packaging film 20 of the product 10 is folded by the corner folding plate 200, the first hot-pressing component 300 can directly heat-seal the folded packaging film 20 of the product 10. After the corner is fully folded, the folded part is directly heat-sealed at the position of the corner folding plate 200, which effectively reduces the risk of the folded part of the packaging film 20 returning to its original state or other defects during the subsequent heat-sealing process. This reduces the number of times the equipment needs to be adjusted, makes it more convenient to use, and increases production efficiency.
[0063] Reference Figure 1 and Figure 2 As shown, in some specific embodiments of this utility model, the hot-seal forming mechanism further includes:
[0064] Two second hot-pressing components 400 are arranged opposite each other along a third direction. The two second hot-pressing components 400 are located at the end of the first conveyor line 100. The two second hot-pressing components 400 are used to receive the product 10 conveyed by the first conveyor line 100 and can heat-press and shape the packaging film 20 of the product 10 along a third direction. They can also heat-seal the packaging film 20 of the product 10 along a second direction. The first direction, the second direction and the third direction are perpendicular to each other.
[0065] Specifically, the third direction is a vertical direction perpendicular to the horizontal plane. The second hot-pressing assembly 400 is used to heat-seal the lower half of the rectangular cylindrical protrusion of the packaging film 20 along the second direction, and can also heat-press and shape the two sides of the packaging film 20 along the third direction.
[0066] In this embodiment, the first conveyor line 100 conveys the product 10 to the second hot pressing assembly 400, and the product 10 is clamped and hot-pressed by the two second hot pressing assemblies 400 along the third direction, so that the packaging film 20 on both sides of the product 10 along the third direction can remain flat.
[0067] Reference Figure 1 and Figure 2 As shown, in some specific embodiments of this utility model, a second hot-pressing assembly 400 includes:
[0068] The second hot pressing section 410 has a second hot pressing surface for receiving and hot pressing the product 10;
[0069] Two third hot-pressing portions 420 are respectively disposed at both ends of the second hot-pressing portion 410 along the second direction. The third hot-pressing portion 420 can rotate relative to the second hot-pressing portion 410 around the first direction and has a first position and a second position. The third hot-pressing portion 420 has a third hot-pressing surface for hot-pressing the packaging film 20 of the product 10.
[0070] The third hot-pressing section 420 is configured such that: in a first position, the third hot-pressing surface is flush with the second hot-pressing surface; and in a second position, the third hot-pressing surface is perpendicular to the second hot-pressing surface.
[0071] Specifically, the second hot-pressing assembly 400 performs hot pressing along a third direction via the second hot-pressing part 410. The two second hot-pressing surfaces clamp the two sides of the product 10 along the third direction, thus shaping the packaging film 20. The third hot-pressing part 420 can rotate relative to the second hot-pressing part 410. In the first position, the third hot-pressing part 420 remains flat, facilitating the subsequent transfer of the product 10. In the second position, the third hot-pressing surface of the third hot-pressing part 420 is perpendicular to the second hot-pressing surface of the second hot-pressing part 410. During rotation, the third hot-pressing surface folds the lower half of the rectangular cylindrical protrusion of the packaging film 20 to the end face of the product 10, and then heat-presses the lower half against the end face of the product 10, achieving a hot-sealing connection between the lower and upper halves of the packaging film 20. Furthermore, the second and third hot-pressing surfaces work simultaneously, saving on equipment costs and increasing processing efficiency.
[0072] Reference Figure 1 and Figure 2 As shown, in some specific embodiments of this utility model, the hot-seal forming mechanism further includes:
[0073] The ejection assembly 500 has an ejection section 510 that can move in a second direction;
[0074] The second conveyor line 600 is arranged along the second direction and is capable of conveying the product 10 along the second direction;
[0075] Two third hot-pressing assemblies 700 are disposed opposite each other on both sides of the second conveyor line 600 along the first direction to hot-press and shape the two sides of the packaging film 20 of the product 10 along the first direction.
[0076] Among them, the launching component 500, the second hot pressing component 400, and the second conveying line 600 are arranged sequentially along the second direction;
[0077] The ejection component 500 is configured such that when the third hot pressing section 420 is in the first position, the ejection section 510 ejects the product 10 from the second hot pressing surface to the second conveyor line 600, and the second conveyor line 600 transfers the product 10.
[0078] Specifically, the second conveyor line 600 is arranged perpendicular to the first conveyor line 100. When the product 10 is transferred from the first conveyor line 100 to the second conveyor line 600, the product 10 changes from being conveyed along the first direction to being conveyed along the second direction. At the same time, the position of the product 10 itself does not change, so that the two ends of the product 10 on the second conveyor line 600 along the first direction are respectively aligned with the two sides of the second conveyor line 600 along the first direction. This facilitates the two third hot pressing components 700 to clamp and hot press the product 10 packaging film 20 along the first direction, realize the hot pressing and shaping of the product 10 along the first direction, realize the shaping of the packaging film 20 on the six sides of the product 10, and complete the production of the product 10 packaging film 20.
[0079] When the product 10 is located on the second hot pressing surface, the product 10 on the second hot pressing surface is moved to the second conveyor line 600 by the movement of the ejector 510 along the second direction, thereby realizing the transfer of the product 10.
[0080] In this embodiment, the ejection component 500 is a telescopic rod, and the telescopic end of the telescopic rod is the ejection part 510. The telescopic end can extend and retract in the second direction to push the product 10 in the second direction. The structure of the second conveyor line 600 is the same as that of the first conveyor line 100, and will not be described again here. The second conveyor line 600 includes a fixed frame for mounting transmission structures such as belts and motors. The ejection component 500 can also be directly connected to the fixed frame or directly fixed to the ground, with only the telescopic end extending and retracting in the second direction.
[0081] Furthermore, when the third hot pressing part 420 is in the first position, the third hot pressing surface and the second hot pressing surface are both flush, so that the pushing part can push the product 10 to move along the second direction on the overall plane formed by the third hot pressing surface and the second hot pressing surface, and move it to the second conveyor line 600. The third hot pressing part 420 will not hinder the transfer of the product 10, making it more reliable to use.
[0082] In some specific embodiments of this utility model, a second hot-pressing assembly 400 further includes:
[0083] The rotation drive is rotatably connected to the third hot pressing unit 420 to drive the third hot pressing unit to switch between the first position and the second position.
[0084] Specifically, the rotation drive is a motor, which can be mounted on a fixed frame or directly fixed to the ground. The output shaft of the motor is connected to the third hot pressing part 420 so that the third hot pressing part 420 rotates around the first direction. The rotation of the third hot pressing part 420 by the motor realizes the angle adjustment between the third hot pressing surface and the second hot pressing surface.
[0085] Reference Figure 1 and Figure 2 As shown, in some specific embodiments of this utility model, the angle plate 200 further includes:
[0086] Motherboard 210;
[0087] The corner portion 220 is provided at one end of the main board portion 210 along the first direction and can guide the product 10 before the main board portion 210. The corner portion 220 has a guide surface 221 that is inclined relative to the conveying surface of the first conveying line 100 to guide and fold one end of the packaging film 20 of the product 10.
[0088] Specifically, when the upper half of the packaging film 20 contacts the guide surface 221, the upper half will bend along the inclined angle of the guide surface 221. When the upper half moves to the bottom of the guide surface 221, the upper half is folded to the end face of the product 10, completing the folding. At the same time, since the upper half has a certain length, it is only necessary to fix the protruding end of the upper half to meet the folding requirement of the upper half. Meanwhile, the protruding end face of the upper half and the root of the packaging film 20 connected to the product 10 are aligned with the hot pressing hole 201, so that the first hot pressing part 310 can heat seal the overlapping packaging film 20.
[0089] Furthermore, the inclination angle of the guide surface 221 relative to the conveying surface is X, where 15°≤X≤45°.
[0090] Reference Figure 1 and Figure 2 As shown, in some specific embodiments of this utility model, the main board portion 210 has an abutting surface 211 for abutting against the product 10 in a second direction; the corner portion 220 has a guide slope 222 that is inclined relative to the abutting surface 211, and the guide slope 222 is connected to the abutting surface 211 in a first direction to guide one end of the product 10.
[0091] Specifically, the guide ramp 222 guides the upper part of the packaging film 20 along one side of the first direction, making it easier for the upper part of the packaging film 20 to pass through the corner plate 200 along the first direction and make a corner fold, resulting in a smoother corner fold. In addition, the distance between the two guide ramps 222 along the second direction is greater than the distance between the two abutment surfaces 211 along the second direction, and the guide ramps 222 also guide the movement of the product 10.
[0092] Furthermore, the inclination angle of the guide slope 222 relative to the abutment surface 211 is Y, where 1°≤Y≤5°.
[0093] A second aspect of this utility model provides a packaging machine, including: the heat-sealing forming mechanism of the first aspect embodiment. It is understood that the packaging machine can more efficiently heat-seal the product 10 through the heat-sealing forming mechanism, thereby improving the production efficiency and yield of the product 10. Other structures of the packaging machine are common knowledge to those skilled in the art and will not be described in detail here.
[0094] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
