Description

Technical Field

[0001] The present invention relates to the technical field of tobacco packaging, and more specifically, to a heat-sealed aluminum film opening device. In addition, the present invention also relates to a heat-sealed aluminum film unfolding and conveying device comprising the heat-sealed aluminum film opening device. Background Art

[0002] The ZB419 packaging unit can wrap the cigarette group with frame paper, heat-sealed aluminum film, hard label paper and transparent paper in sequence. Figure 1 As shown, the heat-sealing aluminum film 10 is provided with a composite area 101 of a composite pressure-sensitive film adhesive tape at the cigarette holder, and the composite area 101 includes a 5 mm front end non-adhesive area 1012 and an adhesive area 1011. The non-adhesive area 1012 utilizes electrostatic adsorption technology to adsorb two layers of aluminum heat-sealing film 10 together.

[0003] The non-glue area 1012 is bonded together with the flap of the hard label paper during the packaging process. When the flap is opened, the pressure-sensitive film of the composite area 101 is opened together. When the flap is closed, the heat-sealed aluminum film 10 is bonded together again by the pressure-sensitive adhesive, which keeps the cigarettes in the box moisturized.

[0004] However, during the debugging and production, since the adsorption force of the non-glue area 1012 is too large, the pressure-sensitive adhesive is too tight, and the initial force direction of the flip cover is approximately parallel to the bonding surface when opening the flip cover, the initial opening torque is large and it is difficult to open. In addition, the flip cover of the cigarette pack is easily damaged or deformed when opened for the first time, which seriously affects the quality of the cigarette pack.

[0005] In summary, how to solve the problem of difficulty in opening a cigarette package for the first time is an urgent problem to be solved by those skilled in the art. Summary of the invention

[0006] In view of this, the purpose of the present invention is to provide a heat-sealed aluminum film opening device, which realizes the first opening of the glue-free area during the unfolding and conveying process of the heat-sealed aluminum film, releases the internal vacuum of the glue-free area, and solves the problem of difficulty in first opening of the cigarette package.

[0007] In addition, the present invention also provides a heat-sealing aluminum film unfolding and conveying device including the above-mentioned heat-sealing aluminum film opening device.

[0008] In order to achieve the above object, the present invention provides the following technical solutions:

[0009] A heat-sealed aluminum film opening device, comprising a mounting shaft connected to a conveying mounting plate and a connecting frame connected to the mounting shaft, wherein a first opener for opening a non-glue area of ​​the heat-sealed aluminum film, a second reset wheel and a third opening wheel for opening an adhesive area of ​​the heat-sealed aluminum film are respectively arranged at a first paper feeding position, a second paper feeding position and a third paper feeding position of the connecting frame;

[0010] The first opener is a triangular opener, and both ends of the first opener are fixedly connected to the connecting frame;

[0011] The second reset wheel is a columnar roller, and the third opening wheel is a shuttle roller with low sides and high middle. Both ends of the second reset wheel and both ends of the third opening wheel are rollingly connected to the connecting frame.

[0012] Preferably, both ends of the second resetting wheel and both ends of the third opening wheel are provided with bearing mounting seats for mounting rolling bearings.

[0013] Preferably, both ends of the first opener are provided with external threads, and the first opener is threadedly connected to the connecting frame.

[0014] Preferably, a positioning pin hole for installing a positioning pin is provided on the connecting frame, positioning bosses are provided at both ends of the first opener, and at least one of the positioning bosses is provided with a positioning hole for engaging with the positioning pin.

[0015] Preferably, the third opening wheel comprises a central shuttle-shaped segment and cylindrical segments arranged on both sides of the central shuttle-shaped segment, and the minimum diameter of the central shuttle-shaped segment is smaller than the diameter of the cylindrical segment.

[0016] Preferably, the central shuttle-shaped segments are symmetrically distributed about the symmetry plane of the connecting frame.

[0017] Preferably, the connecting frame comprises a front connecting frame and a rear connecting frame which are parallel to each other, and the rear connecting frame is threadedly connected to the mounting shaft.

[0018] A heat-sealed aluminum film unwinding and conveying device, comprising a conveying mounting plate, on which a paper roll mounting frame for placing a heat-sealed aluminum film roll, a first paper-passing wheel, an automatic opening device, a fifth paper-passing wheel, a traction conveying roller pair and a brake swing arm are arranged, and on which a second paper-passing wheel and a fourth paper-passing wheel are arranged;

[0019] The heat-sealed aluminum film passes through the first paper-passing wheel, the second paper-passing wheel, the automatic opening device, the fourth paper-passing wheel, and the fifth paper-passing wheel in sequence and then enters between the traction conveying roller pair;

[0020] The automatic opening device is any one of the heat-sealed aluminum film opening devices described above. The side of the heat-sealed aluminum film with the composite area is the front side, and the other side opposite to it is the back side.

[0021] When the heat-sealed aluminum film opening device provided by the present invention is working, the heat-sealed aluminum film passes through the first opener, the second reset wheel and the third opening wheel in sequence. When the heat-sealed aluminum film passes through the first opener, since the first opener is a triangular opener and there is a certain angle between the two adjacent sides, the glue-free area on the front of the heat-sealed aluminum film is opened under the action of its own tension and pulling force; when the heat-sealed aluminum film passes through the second reset wheel, the front of the heat-sealed aluminum film contacts the surface of the columnar roller, so that the two layers of heat-sealed aluminum film in the glue-free area are re-adsorbed together; when the heat-sealed aluminum film passes through the third opening wheel, since the third opening wheel is high in the middle and low on both sides, the adhesive area of ​​the heat-sealed aluminum film is opened when it passes through the third opening wheel.

[0022] Therefore, the heat-sealed film opening device provided by the present invention completely releases the vacuum inside the heat-sealed aluminum film composite area, reduces the torque required for opening the cigarette package for the first time, and reduces the difficulty of opening for the first time.

[0023] In addition, the present invention also provides a heat-sealing aluminum film unfolding and conveying device including the above-mentioned heat-sealing aluminum film opening device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The core of the present invention is to provide a heat-sealed aluminum film opening device, which realizes the first opening of the glue-free area during the unfolding and conveying process of the heat-sealed aluminum film, releases the internal vacuum of the glue-free area, and solves the problem of difficulty in opening the cigarette package for the first time.

[0037] The present invention also provides a heat-sealed aluminum film unfolding and conveying device comprising the heat-sealed aluminum film opening device.

[0038] Please refer to Figure 1-Figure 8 .

[0039] It should be noted that, in this application document, the side of the heat-sealing aluminum film 10 provided with the composite area 101 is referred to as the front side, and the other side thereof is referred to as the back side.

[0040] The heat-sealed aluminum film opening device provided by the present invention comprises a mounting shaft 56 for connecting to a conveying mounting plate and a connecting frame connected to the mounting shaft 56, wherein a first opener 52 for opening a non-glue area 1012 of the heat-sealed aluminum film 10, a second reset wheel 53 and a third opening wheel 54 for opening an adhesive area 1011 of the heat-sealed aluminum film 10 are respectively arranged at a first paper feeding position, a second paper feeding position and a third paper feeding position of the connecting frame; the first opener 52 is a triangular opener, and both ends of the first opener 52 are fixedly connected to the connecting frame; the second reset wheel 53 is a columnar roller, and the third opening wheel 54 is a shuttle roller with low sides and high middle, and both ends of the second reset wheel 53 and the third opening wheel 54 are rollingly connected to the connecting frame.

[0041] Please refer to Figure 3 The cross-section of the first opener 52 is triangular. When the heat-sealed aluminum film 10 passes through the first opener 52, the back side of the heat-sealed aluminum film 10 contacts the surface of the first opener 52. Under the tension of the non-glue area 1012 and the pulling force of the unfolding and conveying device on the heat-sealed aluminum film 10, the non-glue area 1012 is opened.

[0042] Since the angle between the two adjacent sides of the triangular opener is small, the heat-sealed aluminum film 10 needs to be deflected in a larger direction when passing through the two adjacent sides of the triangle, which is more conducive to opening the glue-free area 1012.

[0043] The cross-sectional triangle of the first opener 52 can be set to any shape. Preferably, for the convenience of production, the cross-sectional shape of the first opener 52 is set to an equilateral triangle, and a rounded corner is set at the angle of the equilateral triangle to prevent the heat-sealed aluminum film 10 from tearing at the angle.

[0044] Both ends of the first opener 52 are fixedly connected to the connecting frame, fixing the position of the first paper feeding position on the connecting frame. Compared with the first opener 52 rotating relative to the connecting frame to drive the first paper feeding position to move, the structural reliability is stronger.

[0045] The second reset wheel 53 is set at the second paper feeding position of the connecting frame. When the heat-sealing aluminum film 10 passes around the second reset wheel 53, the front side of the heat-sealing aluminum film 10 contacts the surface of the second reset wheel 53, so that the two layers of heat-sealing aluminum film 10 in the glue-free area 1012 are re-adsorbed, completing the reset of the glue-free area 1012.

[0046] The size, material, etc. of the second reset wheel 53 are determined according to the size of the connecting frame with reference to the size and material of the existing paper feeding wheel, and will not be described in detail here.

[0047] Please refer to Figure 1The composite area 101 is arranged in the middle of the heat-sealed aluminum film 10. To adapt to the above characteristics of the heat-sealed aluminum film 10, the third opening roller 54 is a shuttle roller with low sides and high middle. When the heat-sealed aluminum film 10 passes through the third opening roller 54, the composite area 101 passes through the middle area of ​​the shuttle roller, so that the bonding area 1011 is pushed open.

[0048] The second reset wheel 53 and the third opening wheel 54 are both rollingly connected to the connecting frame, so there is sliding friction between the second reset wheel 53 and the heat-sealing aluminum film 10, and between the third opening wheel 54 and the heat-sealing aluminum film 10, the friction force is small, and the resistance to the unfolding and conveying of the heat-sealing aluminum film 10 is small, which will not affect the unfolding and conveying speed of the heat-sealing aluminum film 10 and cause frequent stops and braking.

[0049] Preferably, please refer to Figure 6 and Figure 7 Both ends of the second reset wheel 53 and the third opening wheel 54 are provided with bearing mounting seats for mounting rolling bearings, and the rolling connection between the second reset wheel 53 and the connecting frame and the third opening wheel 54 and the connecting frame is realized through the rolling bearings.

[0050] When the heat-sealed aluminum film 10 passes, the second reset wheel 53 and the third opening wheel 54 are driven to rotate relative to the connecting frame. The second reset wheel 53 and the heat-sealed aluminum film 10, the third opening wheel 54 and the heat-sealed aluminum film 10 are all rollingly connected, and the friction resistance is small.

[0051] The connecting frame is used to provide installation space for the first opener 52, the second reset wheel 53 and the third opening wheel 54. Preferably, the connecting frame includes a front connecting frame 51 and a rear connecting frame 55 parallel to each other, and the rear connecting frame 55 is threadedly connected to the installation shaft 56.

[0052] In this embodiment, the first opener 52 and the third opening wheel 54 are used to open the glue-free area 1012 and the adhesive area 1011 respectively, releasing the vacuum inside the glue-free area 1012, solving the problem of electrostatic vacuum adsorption in the glue-free area 1012, thereby reducing the torque required for the first opening of the cigarette pack and reducing the difficulty of opening the cigarette pack for the first time.

[0053] At the same time, the friction resistance between the heat-sealed aluminum film opening device provided in this embodiment and the heat-sealed aluminum film 10 is small, which will not affect the normal unfolding and conveying process of the heat-sealed aluminum film 10.

[0054] In addition, an odd number of paper feeding positions are arranged in the heat-sealing aluminum film opening device provided in this embodiment, and the orientation of the heat-sealing aluminum film 10 when contacting the subsequent structure is not changed.

[0055] It should be noted that in order not to change the orientation of the heat-sealed aluminum film 10 when in contact with the subsequent structure, the number of paper feeding positions in the heat-sealed aluminum film opening device must be an odd number. The increase in paper feeding positions is conducive to completely releasing the vacuum in the glue-free area 1012, and on the other hand, it will increase the friction resistance between the heat-sealed aluminum films 10. Excessive friction resistance will cause the heat-sealed aluminum film 10 to be transported too slowly.

[0056] On the basis of the above embodiment, in order to achieve a fixed connection between the first opener 52 and the connecting frame, both ends of the first opener are provided with external threads, and the first opener 52 is threadedly connected to the connecting frame, which is convenient for processing and assembly.

[0057] Preferably, in order to facilitate assembly and positioning, a positioning pin hole for installing a positioning pin is provided on the connecting frame, and positioning bosses 521 are provided at both ends of the first opener 52, and at least one positioning boss 521 is provided with a positioning hole 522 for engaging with the positioning pin.

[0058] The positioning boss 521 is used to position the first opener 52 in the axial direction of the connecting frame; the positioning pin is used to prevent the first opener 52 from rotating relative to the mounting frame.

[0059] Please refer to Figure 3-Figure 5 The end of the first opener 52 with a positioning hole 522 is the positioning end, and the end without a positioning hole 522 is the mounting end. During installation, align the positioning hole 522 of the positioning end with the positioning pin hole on the connecting frame, and connect the mounting end, the positioning end and the mounting frame through threads; install the positioning pin in the positioning pin hole, and the positioning pin passes through the positioning hole 522.

[0060] In addition, a flange connection between the connecting frame and the first opener 52 may also be provided.

[0061] On the basis of the above-mentioned embodiment, the structure of the third opening wheel 54 is limited. The third opening wheel 54 may include a central shuttle-shaped section and cylindrical sections arranged on both sides of the central shuttle-shaped section. The minimum diameter of the central shuttle-shaped section is smaller than the diameter of the cylindrical section, thereby avoiding the heat-sealed aluminum film 10 from deviating when passing around the third opening wheel 54.

[0062] The length, minimum diameter, maximum diameter of the central shuttle-shaped segment and the diameter of the cylindrical segment need to be determined according to factors such as the width of the heat-sealing aluminum film 10 and the width of the composite area 101 in actual production.

[0063] For example, in a specific embodiment, the length of the central shuttle section of the third opening wheel 54 is 40 mm, the maximum diameter is 16 mm, the minimum diameter is 6 mm, and the diameter of the cylindrical sections on both sides is 16 mm.

[0064] Preferably, considering that the composite area 101 is disposed in the center of the heat-sealing aluminum film 10, the central shuttle-shaped segments are symmetrically distributed about the symmetry plane of the connecting frame.

[0065] In addition to the above-mentioned heat-sealed aluminum film opening device, the present invention also provides a heat-sealed aluminum film unfolding and conveying device including the heat-sealed aluminum film opening device disclosed in the above-mentioned embodiment.

[0066] Please refer to Figure 8 The heat-sealed aluminum film unfolding and conveying device comprises a conveying installation plate, on which a paper roll mounting frame 1 for placing a heat-sealed aluminum film roll 9, a first paper-passing wheel 3, an automatic opening device 5, a fifth paper-passing wheel 7, a traction conveying roller pair 8 and a brake swing arm 2 are arranged, and the brake swing arm 2 is provided with a second paper-passing wheel 4 and a fourth paper-passing wheel 6; the heat-sealed aluminum film 10 passes through the first paper-passing wheel 3, the second paper-passing wheel 4, the automatic opening device 5, the fourth paper-passing wheel 6, and the fifth paper-passing wheel 7 in sequence and then enters between the traction conveying roller pair 8; the automatic opening device 5 is the heat-sealed aluminum film opening device disclosed in the above embodiment.

[0067] The wrap angle of the heat-sealed aluminum film 10 at the first paper-passing wheel 3 changes with the diameter of the heat-sealed aluminum film roll 9 on the paper roll mounting frame 1, and the wrap angle is unstable, which is not suitable as the location for the automatic opening device 5. The second paper-passing wheel 4 and the fourth paper-passing wheel 6 are installed on the brake swing arm 2 and swing back and forth with the brake swing arm 2, and the distance between the second paper-passing wheel 4 and the fourth paper-passing wheel 6 is small and the space size is limited; the fifth paper-passing wheel 7 is set close to the traction conveying roller pair 8, and the space size is relatively limited. Therefore, the automatic opening device 5 is set at the original third paper-passing wheel position.

[0068] In this embodiment, the automatic opening device 5 can effectively release the vacuum of the glue-free area 1012, effectively improving the problem of difficulty in opening the cigarette package for the first time. The automatic opening device 5 is used to replace the original third paper-passing wheel, and there is no need to change other structures of the heat-sealed aluminum film unfolding and conveying device, so the modification cost is low.

[0069] It should be noted that in the present application document, the first, second, third, fourth and fifth of the first opener 52, the second reset wheel 53 and the third opening wheel 54, the first paper wheel 3, the second paper wheel 4, the third paper wheel, the fourth paper wheel 6 and the fifth paper wheel 7 are only used to distinguish the different positions and do not contain any limitation on the order.

[0070] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0071] The above is a detailed introduction to the heat-sealed aluminum film unfolding and conveying device and the opening device provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
