Description

Technical Field

[0001] This application relates to the field of packaging technology, and in particular to an aluminum foil paper feeding device and a cigarette packaging machine. Background Technology

[0002] Currently, cigarette packaging machines are generally used to package cigarettes. Cigarettes are usually wrapped in a layer of aluminum foil to keep them moist and fragrant, while also preventing them from getting moldy. The packaging process of cigarette packaging machines involves the conveying, stamping, cutting, and wrapping of aluminum foil.

[0003] In related technologies, cigarette packaging machines are generally equipped with an aluminum foil feeding device to feed and position the aluminum foil before wrapping the cigarettes, ensuring accurate alignment between the cigarettes and the aluminum foil and ensuring the effective wrapping of the cigarettes by the aluminum foil.

[0004] However, cigarette packaging machines are generally equipped with a large number of rollers. When the rollers rotate, they continuously vibrate the aluminum foil, causing the aluminum foil to shake and affecting the accuracy of the alignment between the cigarette and the aluminum foil. Utility Model Content

[0005] Therefore, it is necessary to provide an aluminum foil feeding device and a cigarette packaging machine to address the problem that the rollers of the cigarette packaging machine continuously vibrate the aluminum foil during rotation, causing the aluminum foil to shake and affecting the alignment accuracy between the cigarette and the aluminum foil.

[0006] On one hand, this application provides an aluminum foil paper feeding device, the aluminum foil paper feeding device comprising:

[0007] The lower cardboard component includes a connecting structure, a first mounting structure, and a second mounting structure. The first mounting structure and the second mounting structure are spaced apart from each other and are both connected to the connecting structure.

[0008] A first spring sheet is connected to the first mounting structure. A first gap is provided between the first spring sheet and the lower cardboard component. The first gap is used to accommodate aluminum foil. The first mounting structure is provided with a first positioning groove. The first spring sheet is connected to a first clamping block. The first clamping block is movably engaged with the first positioning groove. When the aluminum foil is placed in the first gap, the first clamping block is used to clamp the aluminum foil in the first positioning groove.

[0009] The second spring sheet is connected to the second mounting structure. A second gap is provided between the second spring sheet and the lower cardboard component. The second gap is used to accommodate the aluminum foil. The second mounting structure is provided with a second positioning groove. The second spring sheet is connected to a second clamping block. The second clamping block is movably engaged with the second positioning groove. When the aluminum foil is placed in the second gap, the second clamping block is used to clamp the aluminum foil in the second positioning groove.

[0010] The aforementioned aluminum foil feeding device, with a first spring plate connected to a first pressing block that is movably engaged in a first positioning groove, and a second spring plate connected to a second pressing block that is movably engaged in a second positioning groove, helps to improve the positioning effect of the aluminum foil by utilizing the elastic pressure of the first and second spring plates, the pressing and limiting effect of the first pressing block and the first positioning groove, and the pressing and limiting effect of the second pressing block and the second positioning groove. This prevents the aluminum foil from shaking, thereby ensuring the accuracy of the alignment between the cigarette and the aluminum foil during the subsequent cigarette wrapping process and improving the wrapping effect of the cigarette. In addition, this application uses a first clamping block that is movably engaged with the first positioning groove and a second clamping block that is movably engaged with the second positioning groove. This helps to limit the position of the first and second clamping blocks in the length direction of the connecting structure, thus preventing the aluminum foil from shifting in the length direction of the connecting structure due to the offset and vibration of the first and second clamping blocks in the length direction of the connecting structure. This further improves the positioning effect of the aluminum foil.

[0011] In one embodiment, the first clamping block is provided with a first guide slope, which is inclined in a direction away from the first positioning groove; the second clamping block is provided with a second guide slope, which is inclined in a direction away from the second positioning groove.

[0013] In one embodiment, the lower cardboard component further includes a guide strip connected to the connecting structure. At least a portion of the guide strip protrudes relative to the surface of the lower cardboard component, and the amount of protrusion of the guide strip relative to the surface of the lower cardboard component gradually increases along the length direction of the guide strip and away from the connecting structure.

[0014] In one embodiment, the guide bar includes an interconnected clearance portion and a limiting portion. The clearance portion is connected to the connecting structure and is arranged to avoid the surface of the lower cardboard piece in a direction away from the first spring sheet. The thickness of the limiting portion gradually increases in a direction away from the clearance portion.

[0015] In one embodiment, the connecting structure is provided with a fifth guide slope, which is inclined toward the surface away from the first spring sheet.

[0016] In one embodiment, the first mounting structure is provided with a first mounting groove, the first spring sheet is connected to a first snap-fit ​​block, and the first snap-fit ​​block is engaged with the first mounting groove in the length direction of the connecting structure; the second mounting structure is provided with a second mounting groove, the second spring sheet is connected to a second snap-fit ​​block, and the second snap-fit ​​block is engaged with the second mounting groove in the length direction of the connecting structure.

[0017] In one embodiment, the first mounting groove is provided with a first locking hole, and the first snap-fit ​​block is provided with a second locking hole. The first locking hole and the second locking hole are aligned with each other and locked together by a first locking member. The second mounting groove is provided with a third locking hole, and the second snap-fit ​​block is provided with a fourth locking hole. The third locking hole and the fourth locking hole are aligned with each other and locked together by a second locking member.

[0018] In one embodiment, the first spring sheet has a first protective paper boundary, and the second spring sheet has a second protective paper boundary. The first protective paper boundary and the second protective paper boundary are located at the outermost edges of the first spring sheet and the second spring sheet, respectively, along the length direction of the connecting structure. The first protective paper boundary and the second protective paper boundary are provided with a first preset distance. The first preset distance is configured such that when the aluminum foil is received in the first gap and / or the second gap, the aluminum foil is completely placed between the first protective paper boundary and the second protective paper boundary.

[0019] On the other hand, this application provides a cigarette packaging machine, which includes the above-mentioned aluminum foil paper feeding device. Attached Figure Description

[0032] Please see Figure 1 In one embodiment, this application provides an aluminum foil paper feeding device 10, which may include a paper feeding component 100, a first spring sheet 200 and a second spring sheet 300.

[0033] Combined Figure 1 and Figure 2 As shown, the lower cardboard component 100 may include a connecting structure 110, a first mounting structure 120, and a second mounting structure 130. The first mounting structure 120 and the second mounting structure 130 are spaced apart from each other and are both connected to the connecting structure 110. A first spring sheet 200 is connected to the first mounting structure 120. A first gap 200a is provided between the first spring sheet 200 and the lower cardboard component 100, and the first gap 200a is used to accommodate the aluminum foil 20. The first mounting structure 120 is provided with a first positioning groove 121. Figure 4 As shown, correspondingly, the first spring sheet 200 is connected to the first clamping block 210, which is movably engaged with the first positioning groove 121. When the aluminum foil 20 is placed in the first gap 200a, the first clamping block 210 is used to clamp the aluminum foil 20 in the first positioning groove 121. The second spring sheet 300 is connected to the second mounting structure 130, and a second gap 300a is provided between the second spring sheet 300 and the lower cardboard component 100. The second gap 300a is used to accommodate the aluminum foil 20. The second mounting structure 130 is provided with a second positioning groove 131, and the second spring sheet 300 is connected to the second clamping block 310, which is movably engaged with the second positioning groove 131. When the aluminum foil 20 is placed in the second gap 300a, the second clamping block 310 is used to clamp the aluminum foil 20 in the second positioning groove 131.

[0034] It should be noted that the first spring sheet 200 and the second spring sheet 300 have elastic deformation capability, that is, under the action of external force, the first spring sheet 200 and the second spring sheet 300 can undergo elastic deformation. In the embodiment of this application, during the paper feeding process of the aluminum foil 20, the first spring sheet 200 and the second spring sheet 300 are pushed apart away from the paper feeding part 100 by the abutment action of the aluminum foil 20, and under the elastic pressure of the first spring sheet 200 and the second spring sheet 300, the aluminum foil 20 is clamped between the first pressing block 210 and the first positioning groove 121, and between the second pressing block 310 and the second positioning groove 131.

[0035] The aforementioned aluminum foil feeding device 10 is configured such that a first pressing block 210 is connected to a first spring plate 200, and the first pressing block 210 is movably engaged with a first positioning groove 121; and a second pressing block 310 is connected to a second spring plate 300, and the second pressing block 310 is movably engaged with a second positioning groove 131. This configuration helps to improve the positioning effect of the aluminum foil 20 by utilizing the elastic pressure of the first spring plate 200 and the second spring plate 300, the pressing and limiting effect of the first pressing block 210 and the first positioning groove 121, and the pressing and limiting effect of the second pressing block 310 and the second positioning groove 131, thereby preventing the aluminum foil 20 from shaking. This ensures the accuracy of the alignment between the cigarette and the aluminum foil 20 during the subsequent cigarette wrapping process, and improves the wrapping effect of the cigarette.

[0036] In addition, by movably engaging the first clamping block 210 with the first positioning groove 121 and the second clamping block 310 with the second positioning groove 131, this application helps to achieve a limiting effect on the first clamping block 210 and the second clamping block 310 in the length direction X of the connecting structure 110. This can prevent the aluminum foil 20 from shifting in the length direction of the connecting structure 110 due to the offset and vibration of the first clamping block 210 and the second clamping block 310 in the length direction X of the connecting structure 110, thus further improving the positioning effect of the aluminum foil 20.

[0037] In other words, by movably engaging the first clamping block 210 with the first positioning groove 121 and movably engaging the second clamping block 310 with the second positioning groove 131, this application can ensure that the first clamping block 210 and the second clamping block 310 exert clamping force on the aluminum foil 20 only in the thickness direction of the connecting structure 110, and do not exert offset pulling force in the length direction of the connecting structure 110. This can ensure the centered placement of the aluminum foil 20 and improve the positioning effect of the aluminum foil 20.

[0038] Please see Figure 4In some embodiments, the first pressing block 210 may be provided with a first guide slope 210a, which is inclined away from the first positioning groove 121; the second pressing block 310 is provided with a second guide slope 310a, which is inclined away from the second positioning groove 131. The first guide slope 210a and the second guide slope 310a are used to abut and guide the aluminum foil 20, which helps to avoid the paper jamming phenomenon of the aluminum foil 20 and improve the paper feeding smoothness of the aluminum foil 20.

[0039] Please continue reading. Figure 4 In some embodiments, the first spring sheet 200 includes a first spring body 201 and a first spring arm 202 connected to each other. The first spring arm 202 is provided with a third guide slope 202a, which is inclined in a direction away from the surface of the lower paperboard 100. The second spring sheet 300 includes a second spring body 301 and a second spring arm 302 connected to each other. The second spring arm 302 is provided with a fourth guide slope 302a, which is inclined in a direction away from the surface of the lower paperboard 100. Similarly, the third guide slope 202a and the fourth guide slope 302a are used to abut and guide the aluminum foil 20, which helps to avoid the paper jamming phenomenon of the aluminum foil 20 and improve the smoothness of the paper feeding of the aluminum foil 20.

[0040] Please see Figure 2 In some embodiments, the connecting structure 110 may be provided with a fifth guide slope 110a. The fifth guide slope 110a is inclined in the direction away from the surface of the first spring sheet 200. Similarly, the fifth guide slope 110a is used to abut and guide the aluminum foil 20, which helps to avoid the paper jamming phenomenon of the aluminum foil 20 and improve the paper feeding smoothness of the aluminum foil 20.

[0041] It is worth noting that, according to the above embodiments of this application, the third guide slope 202a and the fifth guide slope 110a can be inclined in opposite directions, and the fourth guide slope 302a and the fifth guide slope 110a can also be inclined in opposite directions. This helps to expand the opening of the paper inlet of the aluminum foil 20 and improve the paper feeding smoothness of the aluminum foil 20.

[0042] Please see Figure 1 and Figure 2In some embodiments, the lower cardboard component 100 may further include a guide strip 140, which is connected to the connecting structure 110. At least a portion of the guide strip 140 protrudes relative to the surface of the lower cardboard component 100, and the amount of protrusion of the guide strip 140 relative to the surface of the lower cardboard component 100 gradually increases along the length direction of the guide strip 140 and in a direction away from the connecting structure 110. This ensures that during the paper feeding process of the aluminum foil 20 on the surface of the lower cardboard component 100, it will eventually abut against the protruding surface of the guide strip 140, thereby limiting the paper feeding action of the aluminum foil 20.

[0043] It should be noted that the surface of the aforementioned lower cardboard piece 100 refers to the surface opposite to the first spring piece 200 and / or the second spring piece 300.

[0044] Please continue reading. Figure 2 In some embodiments, the guide bar 140 includes an interconnected clearance portion 141 and a limiting portion 142. The clearance portion 141 is connected to the connecting structure 110, allowing the aluminum foil 20 to be fed onto the surface of the clearance portion 141 first, increasing the feeding length of the aluminum foil 20. Furthermore, the clearance portion 141 is arranged away from the surface of the feeding plate 100, thus avoiding contact interference between the guide bar 140 and the aluminum foil 20, thereby reducing the impact of the guide bar 140 on the clamping effect of the aluminum foil 20 on the first clamping block 210 and the first positioning groove 121, and the second clamping block 310 and the second positioning groove 131. Further, the thickness of the limiting portion 142 gradually increases away from the clearance portion 141, enabling the limiting portion 142 to position the aluminum foil 20 during feeding. This achieves both clamping and limiting effects on the aluminum foil 20 without affecting its clamping effect.

[0045] Please see Figure 2 In some embodiments, the first mounting structure 120 is provided with a first mounting groove 122, combined with Figure 4 As shown, the first spring sheet 200 is connected to a first locking block 220, which is locked and engaged with the first mounting groove 122 in the length direction X of the connecting structure 110. The second mounting structure 130 is provided with a second mounting groove 132, and the second spring sheet 300 is connected to a second locking block 320, which is locked and engaged with the second mounting groove 132 in the length direction X of the connecting structure 110. This helps to improve the limiting effect of the first spring sheet 200 and the second spring sheet 300 in the length direction of the connecting structure 110, thereby reducing the dragging effect of the first spring sheet 200 and the second spring sheet 300 on the aluminum foil 20 due to shaking, and improving the positioning accuracy of the aluminum foil 20.

[0046] Please continue to combine Figure 2 and Figure 4As shown, in some embodiments, the first mounting groove 122 is provided with a first locking hole 122a, and the first snap-fit ​​block 220 is provided with a second locking hole 220a. The first locking hole 122a and the second locking hole 220a are aligned with each other and locked together by a first locking member (not shown).

[0047] The second mounting groove 132 is provided with a third locking hole 132a, and the second snap-fit ​​block 320 is provided with a fourth locking hole 320a. The third locking hole 132a and the fourth locking hole 320a are aligned with each other and locked together by a second locking member (not shown). This enables the first spring plate 200 to be stably fixed relative to the first mounting structure 120, and the second spring plate 300 to be stably fixed relative to the second mounting structure 130.

[0048] Optionally, the aforementioned first locking member and second locking member may be implemented as bolts or locking pins, etc.

[0049] Please see Figure 1 In some embodiments, the first spring sheet 200 has a first protective paper boundary 200b, and the second spring sheet 300 has a second protective paper boundary 300b. The first protective paper boundary 200b and the second protective paper boundary 300b are located on the outermost sides of the first spring sheet 200 and the second spring sheet 300 respectively along the length direction X of the connecting structure 110. The first protective paper boundary 200b and the second protective paper boundary 300b are provided with a first preset distance d1. The first preset distance d1 is configured such that when the aluminum foil 20 is received in the first gap 200a and / or the second gap 300a, the aluminum foil 20 is completely placed between the first protective paper boundary 200b and the second protective paper boundary 300. This helps to prevent the aluminum foil 20 from jumping out of the boundary of the first spring sheet 200 or the second spring sheet 300, thereby improving the protection of the aluminum foil 20.

[0050] Please continue reading. Figure 1 In some embodiments, the first spring sheet 200 may have a first preset width d11, and the value of the first preset width d11 may be in the range of 30mm-34mm, such as 30mm, 31mm, 32mm, 33mm or 34mm.

[0052] Optionally, the aforementioned first preset width d11 and second preset width d12 can be set to the same size or different sizes, which helps to improve the flexibility of adjusting the first preset spacing d1 and improve the protective effect on the aluminum foil 20.

[0053] Preferably, the first preset width d11 can be 32mm; the second preset width d12 can be 32mm.

[0054] In some embodiments, please refer to Figure 2 The bottom edge of the first positioning groove 121 and / or the second positioning groove 131 is provided with a second preset distance d2 between the top edge of the connecting structure 110. This helps to improve the positioning accuracy of the first positioning groove 121 and / or the second positioning groove 131, ensuring that the first clamping block 210 can be aligned with the first positioning groove 121 and the second clamping block 310 can be aligned with the second positioning groove 131.

[0056] In some embodiments, please refer to Figure 2 The bottom edge of the first positioning groove 121 and the first locking hole 122a are provided with a third preset distance d3, which helps to improve the positioning accuracy of the first positioning groove 121 relative to the first locking hole 122a and ensures that the first pressing block 210 can be aligned with the first positioning groove 121. The value range of the third preset distance d3 is 54mm-58mm, such as the second preset distance d2, which can be 54mm, 55mm, 56mm, 57mm or 58mm, etc.

[0057] Optionally, the distance between the bottom edge of the second positioning groove 131 and the third locking hole 132a is the same as the aforementioned third preset distance d3. This helps to improve the positioning accuracy of the second positioning groove 131 relative to the third locking hole 132a and ensures that the second pressing block 310 can be aligned with the second positioning groove 131.

[0058] Preferably, the aforementioned third preset spacing d3 can be 56mm.

[0059] In some embodiments, please refer to Figure 4 The distance between the bottom edge of the first pressing block 210 and the second locking hole 220a is the same as the aforementioned third preset distance d3. This ensures that after the first spring sheet 200 is fixedly installed, the first pressing block 210 can be aligned with the first positioning groove 121, thereby improving the pressing effect on the aluminum foil 20.

[0060] In some embodiments, please continue reading Figure 4 The distance between the bottom edge of the second pressing block 310 and the fourth locking hole 320a is the same as the aforementioned third preset distance d3. This ensures that after the second spring sheet 300 is fixedly installed, the second pressing block 310 can be aligned with the second positioning groove 131, thereby improving the pressing effect on the aluminum foil 20.

[0061] In some embodiments, please refer to Figure 2 The fifth guide slope 110a is provided with a first preset angle α1 relative to the surface of the first mounting structure 120.
