Description

Technical Field

[0001] This utility model relates to the field of cigarette packaging technology, and in particular to a heating device and packaging machine for transparent paper of cigarette packs. Background Technology

[0002] The cigarette packs consist of a cardboard box and a transparent paper wrapping. Each cigarette pack is rectangular, and n packs are arranged sequentially along a second direction inside the cardboard box. The transparent paper wrapping is placed around the outside of the cardboard box, forming a seam extending along the second direction. The seam is sealed by heating to adhere the ends of the transparent paper wrapping together.

[0003] Existing packaging machines generally include a soldering iron and a pressure plate. The cigarette packs are held between the soldering iron and the pressure plate. The soldering iron heats the seam. However, since the heating surface of the soldering iron is flat, the side wall of the cigarette pack perpendicular to the heating surface of the soldering iron has high structural strength, while the middle of the cigarette pack is relatively soft. When the cigarette pack is squeezed, the middle of the cigarette pack is always concave. The transparent paper packaging at the seam does not make tight contact with the soldering iron, which easily leads to bulging and air leakage. Not only is the appearance unsightly, but the packaging also loses its airtightness, causing the cigarettes to get damp during storage.

[0004] Therefore, there is an urgent need for a heating device and packaging machine for cigarette transparent paper to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a heating device and packaging machine for cigarette transparent paper, which enables the transparent paper packaging at the seam to fully contact the heating surface of the soldering iron, achieving a beautiful and tight seal.

[0008] First pressure plate;

[0009] The second pressure plate, the first pressure plate and the second pressure plate are arranged in parallel and fixed relative to each other to form a logistics channel, through which the cigarette packs pass;

[0010] The heating assembly includes a first heating element and a second heating element. Both the first heating element and the second heating element can pass through the second pressure plate and enter the logistics channel along a third direction. The heating surface of the first heating element has n-1 clearance grooves equidistantly opened along the second direction. The heating surface of the second heating element is a complete plane.

[0011] As a preferred technical solution of the above-mentioned cigarette transparent paper heating device, the opening end face of the above-mentioned clearance groove is provided with a chamfer.

[0012] As a preferred technical solution of the above-mentioned cigarette transparent paper heating device, it includes a lifting assembly, the lifting assembly includes a first mounting member, and the first heating member and the second heating member are both fixed relative to the first mounting member.

[0013] As a preferred technical solution of the above-mentioned cigarette transparent paper heating device, it further includes an adjustment component, wherein the first heating element and the second heating element are respectively installed on the first mounting component through the adjustment component, and the adjustment component can adjust the distance between the heating element and the first mounting component along the third direction.

[0014] As a preferred technical solution of the above-mentioned cigarette transparent paper heating device, the adjustment component includes a first support plate, a second support plate, a bolt, and a first nut. The first support plate is used to install the first heating element and the second heating element. The second support plate is installed on the first mounting component. The bolt connects the first support plate and the second support plate along the third direction. The bolt can be fixed relative to the second support plate.

[0017] As a preferred technical solution of the above-mentioned cigarette transparent paper heating device, the second support plate is connected to the first mounting component by a first threaded fastener.

[0018] As a preferred technical solution of the above-mentioned cigarette transparent paper heating device, the first support plate is connected to the heating component through the second threaded fastener.

[0019] A packaging machine is also provided, including the aforementioned heating device for cigarette paper.

[0020] The beneficial effects of this utility model are:

[0021] This utility model provides a heating device for cigarette transparent paper. The cigarette pack moves along a first direction and includes n cigarette packs arranged sequentially along a second direction, where n>1. The first and second directions are perpendicular. The heating device includes a first pressure plate, a second pressure plate, and a heating assembly. The first and second pressure plates are parallel and relatively fixed, forming a logistics channel through which the cigarette pack passes. The heating assembly includes a first heating element and a second heating element, both of which can pass through the second pressure plate and enter / exit the logistics channel along a third direction. The heating surface of the first heating element has n-1 equidistant clearance grooves along the second direction, and the heating surface of the second heating element is a complete plane.

[0022] Specifically, during use, if no cigarette pack reaches the first clearance opening, the first heating element is in the first position, located outside the logistics channel. If no cigarette pack reaches the second clearance opening, the second heating element is in the third position, also located outside the logistics channel, thus maintaining the unobstructed flow of the logistics channel. When the cigarette pack moves along the first direction within the logistics channel, upon reaching the first clearance opening, the first heating element moves along the third direction to the second position, located within the logistics channel. The cigarette pack is held between the heating surface of the first heating element and the first pressure plate. The adjacent side walls of two adjacent cigarette packs in the second direction project directly into the clearance groove in the third direction. When the first heating element and the first pressure plate press the cigarette pack together, the side wall of the cigarette pack perpendicular to the heating surface can be inserted into the clearance groove. The heating surfaces on both sides of the clearance groove can then further conform to the central area of ​​the cigarette pack, allowing the transparent paper packaging and the cardboard box packaging to complete the initial heating and bonding. At this point, at most n-1 equidistant openings are formed at the seam of the transparent paper packaging, that is, the opening positions correspond to the positions of the clearance grooves. When the cigarette reaches the second clearance opening, the second heating element moves to the fourth position. The heating of the second heating element heats the seam of the transparent paper packaging again. Since the heating surface of the second heating element is flat, it can smooth out the opening of the part of the transparent paper packaging corresponding to the clearance groove, so that it is sealed after being heated.

[0023] In this way, the seams of the transparent paper packaging are heat-bonded twice, which not only improves the sealing performance of the transparent paper packaging, but also gives it a relatively smooth appearance. Attached Figure Description

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0042] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0043] like Figures 1 to 5 As shown, this utility model provides a heating device for cigarette transparent paper. A cigarette pack 1 moves along a first direction X. The cigarette pack 1 includes n cigarette pouches arranged sequentially along a second direction Y, where n > 1. The first direction X is perpendicular to the second direction Y. The heating device includes a first pressure plate 100, a second pressure plate 200, and a heating component 300. The first pressure plate 100 and the second pressure plate 200 are arranged parallel to each other and relatively fixed, forming a logistics channel 210 through which the cigarette pack 1 passes. The heating component 300 includes a first heating element 310 and a second heating element 320. Both the first heating element 310 and the second heating element 320 can pass through the second pressure plate 200 and enter / exit the logistics channel 210 along a third direction Z. The heating surface of the first heating element 310 has n-1 equidistant clearance grooves 311 along the second direction Y. The heating surface of the second heating element 320 is a complete plane.

[0044] For example, a pack of cigarettes 1 is filled with five cigarette packs. Projected in the third direction Z, the length of each cigarette pack in the second direction Y is H, the wall thickness of the cigarette pack is h, the gap between two adjacent cigarette packs in the second direction Y is D, the width of the clearance groove 311 in the second direction Y is l, and the distance between two adjacent clearance grooves 311 in the second direction Y is L, satisfying that L≤H, l≥(2*h+D). The second pressure plate 200 is provided with a first clearance opening 220 and a second clearance opening 230 at intervals in the first direction X. The first heating element 310 can enter and exit the logistics channel 210 through the first clearance opening 220, and the second heating element 320 can enter and exit the logistics channel 210 through the second clearance opening 230.

[0045] Specifically, during use, if the smoke 1 reaches the first clearance opening 220, the first heating element 310 is in the first position, which is outside the logistics channel 210. If the smoke 1 reaches the second clearance opening 230, the second heating element 320 is in the third position, which is outside the logistics channel 210, thereby keeping the logistics channel 210 unobstructed. When the cigarette pack 1 moves along the first direction X within the logistics channel 210, and reaches the first clearance opening 220, the first heating element 310 moves along the third direction Z to the second position. The second position is located within the logistics channel 210, and the cigarette pack 1 is sandwiched between the heating surface of the first heating element 310 and the first pressure plate 100. The adjacent side walls of two adjacent cigarette packs in the second direction Y project directly onto the clearance groove 311 in the third direction Z. When the first heating element 310 and the first pressure plate 100 press the cigarette pack 1 together, the side wall of the cigarette pack perpendicular to the heating surface can be inserted into the clearance groove 311, and the heating surfaces on both sides of the clearance groove 311 can further conform to the central area of ​​the cigarette pack, so that the transparent paper packaging and the cardboard packaging complete the initial heating and bonding. At this point, at most n-1 equidistant openings are formed at the seam of the transparent paper packaging, that is, the opening positions correspond to the positions of the clearance groove 311. The cigarette pack 1 then reaches the second clearance opening 230, and the second heating element 320 moves to the fourth position. The heating of the second heating element 320 heats the seam of the transparent paper packaging again. Since the heating surface of the second heating element 320 is a plane, it can smooth out the opening of the transparent paper packaging corresponding to the clearance groove 311, so that it is sealed after being heated.

[0046] In this way, the seams of the transparent paper packaging are heat-bonded twice, which not only improves the sealing performance of the transparent paper packaging, but also gives it a relatively smooth appearance.

[0047] Optionally, the opening end face of the clearance groove 311 is chamfered. In this way, by providing a chamfer, the relative width of the clearance groove 311 is increased, and the opening end face of the clearance groove 311 is less likely to tear the transparent packaging paper.

[0048] Optionally, the cigarette paper heating device includes a lifting assembly, which includes a first mounting member 410. A first heating element 310 and a second heating element 320 are both fixed relative to the first mounting member 410. Thus, both the first heating element 310 and the second heating element 320 can enter and exit the logistics channel 210 along the third direction Z via the lifting assembly, and the first heating element 310 and the second heating element 320 move synchronously.

[0049] Optionally, the cigarette paper heating device further includes an adjustment component 500. The first heating element 310 and the second heating element 320 are respectively mounted on the first mounting member 410 via the adjustment component 500. The adjustment component 500 can adjust the distance between the heating element 300 and the first mounting member 410 along the third direction Z. In this way, the relative position between the heating element 300 and the first mounting member 410, that is, the relative position between the heating plane and the first pressure plate 100, can be adjusted according to the specific processing requirements of the batch.

[0050] Optionally, the adjusting assembly 500 includes a first support plate 510, a second support plate 520, a bolt 530, and a first nut 540. The first support plate 510 is used to install the first heating element 310 and the second heating element 320. The second support plate 520 is installed on the first mounting member 410. The bolt 530 connects the first support plate 510 and the second support plate 520 in a third direction Z. The bolt 530 can be fixed relative to the second support plate 520. The first support plate 510 is sandwiched between the nut portion of the bolt 530 and the first nut 540. The first nut 540 is threadedly connected to the bolt 530.

[0051] For example, bolt 530 includes a nut portion and a threaded portion for fixed connection. The threaded portion is inserted into the first support plate 510 and the second support plate 520. A first nut 540 is located between the first support plate 510 and the second support plate 520. The first nut 540 is threadedly connected to the threaded portion of bolt 530. The nut portion and the first nut 540 axially fix the first support plate 510 at the threaded portion. When it is necessary to adjust the distance between the first support plate 510 and the second support plate 520, the first nut 540 can be loosened.

[0052] Optionally, the adjusting assembly 500 also includes a second nut 550 and a third nut 560, both of which are threadedly connected to the bolt 530, and a second support plate 520 is sandwiched between the second nut 550 and the third nut 560.

[0053] For example, both the second nut 550 and the third nut 560 are threadedly connected to the bolt 530. When it is necessary to adjust the distance between the second support plate 520 and the first support plate 510, simply loosen the second nut 550 or the third nut 560. When locking is required, the second nut 550 and the third nut 560 clamp the second support plate 520, fixing it in the third direction Z.

[0054] Optionally, the second support plate 520 has weight-reduction holes 521. This configuration can reduce the weight of the second support plate 520.

[0055] Optionally, the second support plate 520 is connected to the first mounting member 410 via a first threaded fastener 610. This arrangement facilitates the assembly between the second support plate 520 and the first mounting member 410.

[0056] Optionally, the first support plate 510 is connected to the heating assembly 300 via a second threaded fastener 620. This arrangement facilitates the assembly of the first support plate 510 and the heating assembly 300.

[0057] A packaging machine is also provided, including the aforementioned heating device for cigarette paper.

[0058] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention.
