Description

TECHNICAL FIELD

[0001] The utility model relates to packing equipment technical field, concretely is a kind of blocking mechanism and the lifting device for vertical packing machine of paper box of the lifting device. BACKGROUND

[0002] Nowadays, many products use paper boxes as outer packaging, so packaging paper boxes has become an essential link in product manufacturing line. For the paper box packaging link, the traditional horizontal packing machine needs to set each process equipment in horizontal direction in turn, which will occupy a lot of space; to solve this problem, the existing technology has appeared vertical packing machine, that is, each process equipment is set in vertical direction in turn, which can effectively save floor area. One of the indispensable devices in vertical packing machine is lifting device, which is used to realize the transfer of paper box between different height stations; in order to realize this transfer function, the lifting device usually needs to have clamping mechanism and lifting mechanism. As the patent with publication number CN220483732U proposes a kind of packing box lifting device, including clamping arm and lifting mechanism for driving clamping arm to lift as a whole, clamping arm is equipped with driving device, clamping plate and clamping plate, clamping plate specifically includes upper clamping plate on inner clamping plate and lower clamping plate on outer clamping plate; driving device drives upper clamping plate and lower clamping plate to approach or move away from each other, realizes the clamping or release of paper box; lifting mechanism drives upper clamping plate and lower clamping plate to rise or descend at the same time, realizes the transfer of paper box between different stations.

[0003] However, the existing lifting device including the above patent only focuses on realizing the transfer effect of paper box, without considering the risk that the paper box cover buckled by the station is easily bounced out with the lifting movement during the transfer process; once the paper box cover is bounced out, it will hinder the normal progress of subsequent process, and further cause adverse effects. For example, for the packing box with inner cover and outer cover often used for disposable gloves and other products, the next process of buckling inner cover is to buckle outer cover, and if the buckled inner cover is bounced open during the transfer process of packing box, it will directly lead to the failure of buckling outer cover.

[0004] In view of the above, the utility model provides a kind of blocking mechanism for vertical packing machine lifting device of paper box. UTILITY MODEL CONTENT

[0005] The utility model aims at providing a kind of blocking mechanism for vertical packing machine lifting device of paper box and the lifting device, to solve the problem that the existing vertical packing machine of paper box only focuses on realizing the lifting transfer of paper box without considering the risk of paper box cover bouncing out mentioned in the above background technology.

[0006] The utility model is implemented by the following technical solutions:

[0007] The application discloses a blocking mechanism for a lifting device of a carton vertical packaging machine, which is applied to the lifting device of the carton vertical packaging machine, and the lifting device comprises a liftable buckle cover rear transfer clamp plate, the buckle cover rear transfer clamp plate comprises an upper clamp plate and a lower clamp plate located below the upper clamp plate.

[0008] In the technical scheme, the buckle cover rear transfer clamp plate refers to a clamp plate for transferring a carton to a next station after completing buckling of the carton, and in the blocking mechanism, the blocking piece can be lifted synchronously with the buckle cover rear transfer clamp plate under the action of the lifting part, so that the blocking piece can limit and block the carton cover during the transferring process of the carton, thereby effectively preventing the carton cover from being ejected.

[0009] As a further limitation of the scheme, the blocking piece is in the shape of a sheet, a rod, a strip or a block. In actual application, the skilled in the art can select and design according to the situation, and the blocking effect on the carton cover should be achieved.

[0010] As a further limitation of the scheme, the blocking piece is lifted synchronously with the upper clamp plate or the lower clamp plate in the buckle cover rear transfer clamp plate under the action of the lifting part. Through this arrangement, the position of the blocking piece can be adjusted synchronously when the carton is clamped or released, thereby making the operation more convenient and simple.

[0011] As a further limitation of the scheme, the lifting part is connected with the buckle cover rear transfer clamp plate, and the buckle cover rear transfer clamp plate is connected with the blocking piece. This connection mode belongs to the case that the blocking piece is indirectly connected with the lifting part through other components.

[0012] The application discloses a carton vertical packaging machine lifting device, which comprises a liftable buckle cover rear transfer clamp plate, the buckle cover rear transfer clamp plate comprises an upper clamp plate and a lower clamp plate located below the upper clamp plate, and further comprises a lifting mechanism and the above-mentioned blocking mechanism for the carton vertical packaging machine lifting device; the lifting mechanism comprises an upper clamp plate lifting driving mechanism and a lower clamp plate lifting driving mechanism, and the upper clamp plate lifting driving mechanism and the lower clamp plate lifting driving mechanism drive the upper clamp plate and the lower clamp plate to perform lifting movement respectively.

[0013] In the above scheme, since the upper clamping plate and the lower clamping plate are driven to move up and down by the respective corresponding lifting driving mechanisms, the upper clamping plate or the lower clamping plate can be driven separately to move up and down, or the upper clamping plate and the lower clamping plate can be driven together to move up and down synchronously. Based on this, the height distance between the upper clamping plate and the lower clamping plate (i.e. the height parameter of the transfer clamping plate after the cover is buckled) can be adjusted flexibly by separate driving, and then the clamping and release of the carton can be realized. The height position of the upper clamping plate and the lower clamping plate (i.e. the height position of the transfer clamping plate after the cover is buckled) can be adjusted synchronously by driving together, and then the lifting of the transfer clamping plate after the cover is buckled and the carton thereon can be realized, so that the transfer of the carton between different stations can be realized. The blocking mechanism further includes a blocking piece in the blocking mechanism, which can move up and down synchronously with the transfer clamping plate after the cover is buckled under the action of the lifting part, and then can limit and block the cover of the carton during the transfer of the carton.

[0014] As a further limitation of the present scheme, the lifting part in the blocking mechanism includes the upper clamping plate lifting driving mechanism in the lifting device, or the lower clamping plate lifting driving mechanism in the lifting device, or a driving mechanism independent of the lifting device. In actual application, which way is set by the person skilled in the art according to the situation, so as to realize the synchronous lifting of the blocking piece with the transfer clamping plate after the cover is buckled.

[0015] As a further limitation of the present scheme, the lifting part in the blocking mechanism includes the upper clamping plate mounting frame or the lower clamping plate mounting frame in the lifting device, the output end of the upper clamping plate lifting driving mechanism is connected to the upper clamping plate mounting frame, and the upper clamping plate is mounted on the upper clamping plate mounting frame; the output end of the lower clamping plate lifting driving mechanism is connected to the lower clamping plate mounting frame, and the lower clamping plate is mounted on the lower clamping plate mounting frame.

[0016] As a further limitation of the present scheme, the upper clamping plate lifting driving mechanism and the lower clamping plate lifting driving mechanism adopt a ball screw assembly or a belt assembly or a gear and rack assembly or a chain assembly or a linear sliding module. In actual application, which way is set by the person skilled in the art according to the situation, so as to realize the lifting effect.

[0017] As a further limitation of the present scheme, as the blocking piece moves up and down synchronously with the transfer clamping plate after the cover is buckled under the action of the lifting part, the blocking piece moves to the outer cover buckling station, and the blocking piece and the outer cover tongue assembly form an outer cover pre-folding mechanism, and the height position of the blocking piece corresponds to the pre-folding position on the outer cover of the carton; when the outer cover is pre-folded, the blocking piece in the outer cover pre-folding mechanism is located between the outer cover of the carton and the inner cover of the carton.

[0018] In the technical solution, the outer cover buckling station is the next station after the inner cover of the carton is buckled, and the outer cover buckling station usually performs at least two actions of outer cover pre-folding and outer cover insertion (for reference to the tail end limiting type single end sealing box mechanism provided in the patent with the publication number CN219728613U), and the outer cover pre-folding is realized by an outer cover pre-folding mechanism; in the utility model, the outer cover insertion tongue assembly in the outer cover pre-folding mechanism is used to provide pre-folding power, that is, to act on the outer cover of the carton to pre-fold the pre-folding position on the outer cover of the carton; and the blocking piece that reaches the outer cover buckling station together with the transfer clamp plate after buckling is used to play a supporting and guiding role in the pre-folding process. Based on this, the blocking piece can play the functions of preventing the inner cover from being ejected and pre-folding and guiding when the outer cover is buckled, and thus a separate pre-folding and guiding structure (usually including a pre-folding and guiding piece and a power piece, such as the pre-folding and guiding rod and the air cylinder one provided in the patent with the publication number CN219728613U) does not need to be arranged.

[0019] As a further limitation of the present scheme, the blocking piece is in the shape of "L", and the edge of one end of the blocking piece abuts against the pre-folding position on the outer cover of the carton. By arranging the shape of "L", the blocking piece can contact the inner cover with a larger area (in the shape of "L", the plane on one side of the corner) and support the outer cover with the edge of the end, and thus the functions of preventing the inner cover from being ejected and supporting and guiding can be considered.

[0020] The utility model realizes the beneficial effect that:

[0021] The blocking mechanism and the lifting device for the vertical carton packaging machine are provided, the blocking piece and the lifting part are arranged, the blocking piece can be lifted synchronously with the transfer clamp plate after buckling under the action of the lifting part, and thus the carton cover can be limited and blocked in the process of transferring the carton; compared with the existing vertical carton packaging machine that only focuses on the lifting and transfer of the carton and does not consider the risk of the carton cover being ejected, the blocking mechanism can effectively prevent the carton cover from being ejected, and thus the adverse effects caused by the carton cover being ejected can be avoided. In addition, in the carton packaging production line with inner cover and outer cover, the blocking piece can also play a pre-folding and guiding role when the outer cover is pre-folded, and thus a separate pre-folding and guiding structure does not need to be arranged.

[0029] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model.

[0030] Embodiment 1

[0031] Please refer to Figure 1 , Figure 2 and Figure 6 , the embodiment provides a carton vertical packaging machine lifting device, which is applied to the carton 2 with the carton inner cover 8 and the carton outer cover 6, and comprises a cover buckling post transfer clamping plate, a lifting mechanism and a blocking mechanism, and specifically:

[0032] In the embodiment, the cover buckling post transfer clamping plate refers to the clamping plate for transferring the carton 2 to the outer cover buckling station after the carton inner cover 8 is buckled, and the cover buckling post transfer clamping plate comprises the upper clamping plate 1 and the lower clamping plate 3 below the upper clamping plate 1; the blocking piece 4 is located on one side of the cover buckling post transfer clamping plate in the lifting device; the lifting mechanism comprises an upper clamping plate lifting driving mechanism and a lower clamping plate lifting driving mechanism, and the upper clamping plate lifting driving mechanism and the lower clamping plate lifting driving mechanism drive the upper clamping plate 1 and the lower clamping plate 3 to move up and down respectively.

[0033] In the embodiment, the output end of the upper clamping plate lifting driving mechanism is connected with the upper clamping plate mounting frame 9, and the upper clamping plate 1 is mounted on the upper clamping plate mounting frame 9; the output end of the lower clamping plate lifting driving mechanism is connected with the lower clamping plate mounting frame 10, and the lower clamping plate 3 is mounted on the lower clamping plate mounting frame 10. The upper clamping plate lifting driving mechanism and the lower clamping plate lifting driving mechanism can be specifically a ball screw assembly, a belt assembly, a gear and rack assembly, a chain assembly or a linear sliding module; in actual application, the specific mode is set by the person skilled in the art according to the situation, and the lifting effect is achieved.

[0034] The embodiment also provides a blocking mechanism for a lifting device of a paper box vertical packaging machine, which comprises a blocking piece 4 and a lifting part, the lifting part is connected with the blocking piece 4, and the blocking piece 4 is lifted and descended synchronously with the transfer clamping plate after the cover is buckled under the action of the lifting part. In the embodiment, the blocking piece 4 is in the form of a sheet structure with an "L" shape (in other embodiments, a rod-shaped, strip-shaped or block-shaped structure can be selected according to the actual situation, and the utility model does not make special limitation on this, and the function of preventing the inner cover 8 of the paper box from being ejected is achieved); the lifting part comprises a lower clamping plate lifting driving mechanism in the lifting device (in other embodiments, an upper clamping plate lifting driving mechanism in the lifting device can be selected according to the actual situation, or the lifting part is independent of the lifting device, and the like, and the utility model does not make special limitation on this, and the synchronous lifting of the blocking piece 4 with the transfer clamping plate after the cover is buckled is achieved); and a lower clamping plate mounting frame 10. In the embodiment, the blocking piece 4 is directly connected with the lifting part, that is, the blocking piece 4 is connected to the lower clamping plate mounting frame 10, and the blocking piece 4 can be lifted and descended synchronously with the lower clamping plate 3; in other embodiments, the blocking piece 4 can also be indirectly connected with the lifting part, for example, after the transfer clamping plate after the cover is buckled is mounted on the clamping plate mounting frame, the blocking piece 4 is directly connected with the transfer clamping plate (the upper clamping plate 1 or the lower clamping plate 3).

[0035] Based on the above structure, the working principle of the embodiment is as follows:

[0036] Please refer to Figure 1The inner cover plug-in tongue assembly 5 (which is a prior art structure and does not belong to the improvement of the prior art of the utility model, so it will not be expanded here, and the inner cover plug-in device of the packaging box provided in the patent with the publication number CN217706386U can be referred to, and the relevant parts can be adaptively applied to the utility model by the person skilled in the art) is used to buckle the inner cover 8 of the carton, and when the inner cover plug-in tongue assembly 5 is buckled and not completely separated (that is, the inner cover plug-in tongue assembly 5 can also block and limit the buckled inner cover), the blocking piece 4 reaches the front side of the inner cover 8 of the carton and tightly abuts against the inner cover 8 of the carton along with the movement of the lifting part, and the post-buckling transfer clamp plate also moves to the carton 2 along with the lifting part. After the post-buckling transfer clamp plate clamps the carton 2, the inner cover plug-in tongue assembly 5 and the corresponding carton fixing mechanism (not shown in the figure) are withdrawn, the lifting mechanism of the lifting device drives the clamp plate mounting frame to make lifting movement, so as to make the post-buckling transfer clamp plate, the carton 2 and the blocking piece 4 jointly ascend (or descend). Based on this, the embodiment can realize the transfer of the carton 2 after the inner cover is buckled, and can limit and block the inner cover 8 of the carton during the transfer of the carton 2, so as to prevent the inner cover 8 of the carton from being popped out or loosened, thereby affecting the buckling effect of the outer cover.

[0037] Embodiment 2

[0038] Please refer to Figures 1 to 6 The embodiment also provides a carton vertical packaging machine lifting device, which is based on the embodiment 1, and the blocking piece 4 is lifted synchronously with the post-buckling transfer clamp plate under the action of the lifting part, and the blocking piece 4 and the outer cover plug-in tongue assembly 7 constitute an outer cover pre-folding mechanism after the blocking piece 4 is transferred to the outer cover buckling station.

[0039] When the outer cover is pre-folded, the blocking piece 4 is located between the outer cover 6 of the carton and the inner cover 8 of the carton, and the height position of the blocking piece 4 corresponds to the pre-folding position on the outer cover 6 of the carton.

[0040] In the embodiment, the blocking piece 4 is a sheet structure with an "L" shape, wherein the plane on one side of the corner abuts against the inner cover 8 of the carton, and the edge of the plane end on the other side of the corner abuts against the pre-folding position on the outer cover 6 of the carton; the outer cover 6 of the carton comprises a rectangular portion 11 and a plug-in tongue 12 connected to the outer side edge of the rectangular portion 11, and the pre-folding position is the connection between the plug-in tongue 12 and the rectangular portion 11.

[0041] In this embodiment, the outer cover tongue assembly 7 includes a power part and an output part, wherein the output part includes a push plate 13 directed to the pre-folding position of the rectangular portion 11 on the outer cover 6 of the carton, and a folding plate 14 directed to the tongue 12 on the outer cover 6 of the carton. It should be particularly pointed out that, in fact, before the outer cover tongue assembly 7 performs work, the cover assembly needs to first flip down the outer cover 6 of the carton, so that the blocking piece 4 abuts against the pre-folding position on the outer cover 6 of the carton; the specific setting mode and working principle of the cover assembly, the power part of the outer cover tongue assembly 7 and other related structures required for buckling the outer cover are all prior art and do not belong to the improvement of the prior art by the present utility model, so this place will not be repeated here. For reference, a tail end limiting type single end sealing box mechanism is proposed in the patent with the publication number CN219728613U, and the related parts can be adaptively applied to the present patent by the person skilled in the art.

[0042] Based on the above structure, the working principle of the present embodiment is as follows:

[0043] After the cover buckling rear transfer clamp plate brings the carton 2 to the outer cover buckling station, the outer cover buckling station receives the carton 2 (at this time, the carton 2 is fixed by the carton fixing mechanism at the station), the outer cover 6 of the carton is flipped down, the outer cover tongue assembly 7 acts towards the outer cover 6 of the carton, wherein the push plate 13 pushes the outer cover 6 of the carton in the buckling direction, the folding plate 14 folds the tongue 12 in the buckling direction, and the end edge of the blocking piece 4 supports and guides during the pre-folding process. After the pre-folding of the outer cover 6 of the carton is completed, the cover buckling rear transfer clamp plate and the blocking piece 4 are withdrawn from the outer cover buckling station and returned to the inner cover buckling station of the carton to wait for the next cycle operation.

[0044] It should be particularly pointed out that the lifting device needs to produce necessary translational motion between the carton 2 during actual work; for example, when the cover buckling rear transfer clamp plate is withdrawn from the outer cover buckling station, the cover buckling rear transfer clamp plate needs to first produce horizontal misalignment between the carton 2, and then continue to descend (or ascend) to return to the inner cover buckling station of the carton; the translational motion can be achieved by driving the cover buckling rear transfer clamp plate to translate or the carton 2 to translate, and the specific structure setting mode belongs to the prior art, so it will not be repeated in this embodiment. For reference, a translation mechanism is proposed in the patent with the publication number CN220483732U, and the related parts can be adaptively applied to the present patent by the person skilled in the art.

[0045] The technical scheme provided by the utility model is as above, the parts which are not described in detail or expanded in the above scheme are all prior art, do not belong to the improvement of the prior art by the utility model, and also do not belong to the protection range of the technical scheme of the utility model, therefore, the parts are not described in detail in this paper. Of course, the above content is only the preferred embodiment of the utility model, and cannot be considered as limiting the scope of the embodiment of the utility model. The utility model is also not limited to the above examples, and the equivalent changes and improvements made by the ordinary skilled in the art within the essential scope of the utility model should all belong to the patent coverage range of the utility model.
