Description

Technical Field

[0001] This utility model relates to the field of tobacco packaging technology, and in particular to a cigarette pack lifting device. Background Technology

[0002] During the tobacco packaging process, a tobacco pack lifting device is needed to move the tobacco packs from a lower position to a higher designated position to facilitate further processing of the tobacco packs, ensuring a smooth transition of the tobacco packs throughout the production line and guaranteeing the continuity of the tobacco pack production process.

[0003] Currently, the cigarette pack lifting device mainly adopts the belt and pressure plate drive method, that is, a conveying channel is formed between the conveyor belt and the pressure plate opposite it. In the conveying channel, the cigarette pack is driven by the clamping friction of the conveyor belt and the pressure plate to lift the cigarette pack up with the conveyor belt to the designated position.

[0004] However, due to the long-term clamping and friction between the conveyor belt and the pressure plate on the cigarette packs, the conveyor belt and pressure plate are prone to wear, causing the cigarette packs to slip and resulting in conveying deviation. Furthermore, the current cigarette pack lifting device does not have a positioning and diversion function for the cigarette packs, which makes it easy for the individual cigarette packs in the conveying channel to stick together, which is not conducive to the subsequent processing and packaging of individual cigarette packs.

[0005] To address the above problems, there is an urgent need for a cigarette pack lifting device. Utility Model Content

[0006] The purpose of this invention is to provide a cigarette pack lifting device that can ensure that the cigarette packs will not be deviated in the conveying channel and can slow down the upward movement speed of the pressed cigarette packs along the Z-axis to prevent the cigarette packs from sticking together.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] The cigarette pack lifting device includes:

[0009] A vertical frame extending along the Z-axis;

[0010] The conveyor belt is rotatably mounted within the vertical frame;

[0011] A long plate extends along the Z-axis, is disposed within the vertical frame and placed inside the conveyor belt, and forms a conveying channel between the long plate and the first side belt of the conveyor belt along the Y-axis, the conveying channel being used to convey cigarette packs from bottom to top along the Z-axis;

[0012] The elastic element is provided at intervals along the Z-axis on one side of the long plate facing the conveying channel. When the cigarette pack is conveyed along the Z-axis to the elastic element to press against the elastic element, the elastic element reacts and presses the cigarette pack against the first side belt of the conveyor belt to guide the cigarette pack and decelerate the cigarette pack.

[0013] As an optional solution, the long board includes:

[0014] Multiple conveyor plates are provided, and the conveyor plates extend along the Z-axis;

[0015] A connecting plate is used to connect two adjacent conveying plates, and the elastic element is provided at intervals along the Z-axis on one side of the connecting plate facing the conveying channel.

[0016] As an optional solution, the connecting plate is provided with a plurality of elastic elements, and the elastic elements are evenly arranged.

[0017] As an optional solution, the elastic element includes:

[0018] A flat plate, the position of which is adjustablely mounted to the connecting plate;

[0019] An arc-shaped plate, one end of which is connected to the flat plate, and the other end is arc-shaped and facing the cigarette pack, the arc-shaped plate is used to guide and cushion the pressure on the cigarette pack.

[0020] Alternatively, the flat plate and the curved plate can be a single integrated structure.

[0021] As an option, the distance between the long plate and the first side belt along the Y-axis is adjustable to adjust the size of the conveying channel along the Y-axis.

[0022] As an optional solution, the cigarette pack lifting device further includes:

[0023] A U-shaped seat is connected to the conveyor plate, and the second side of the conveyor belt away from the conveyor channel passes through the U-shaped seat;

[0024] An adjusting seat, one end of which is connected to the outer side of the U-shaped seat away from the second side strip, and the other end of which can be adjusted along the Y-axis position and mounted on the vertical frame.

[0025] As an optional solution, the adjustment seat includes:

[0026] The first plate is connected to the outer side of the U-shaped seat away from the second side strip;

[0027] The second plate is vertically connected to the first plate to form an L-shaped structure, and the second plate is adjustablely mounted on the vertical frame along the Y-axis.

[0028] A reinforcing plate is connected between the first plate and the second plate.

[0029] As an optional solution, the cigarette pack lifting device further includes:

[0030] Two rollers are arranged opposite each other along the Z-axis within the vertical frame. The opposite ends of the conveyor belt are respectively fitted onto the two rollers. The rotation of the rollers can drive the conveyor belt to move.

[0031] As an optional solution, a tensioning wheel is installed in an adjustable position within the vertical frame, and the second side of the conveyor belt away from the conveying channel is wound around the tensioning wheel. The tensioning wheel is used to adjust the tension of the conveyor belt.

[0032] The beneficial effects of this utility model are as follows:

[0033] By placing both the conveyor belt and the long plate within a vertical frame, with the long plate extending along the Z-axis and positioned inside the conveyor belt, and then along the Y-axis, a conveying channel is formed between the long plate and the first side of the conveyor belt. This conveying channel is used to transport cigarette packs from bottom to top along the Z-axis. Specifically, within the conveying channel, the clamping friction between the conveyor belt and the long plate causes the cigarette packs to rise with the conveyor belt, lifting them to a designated position. Simultaneously, elastic elements are spaced along the Z-axis on the side of the long plate facing the conveying channel. When a cigarette pack is transported along the Z-axis to the elastic element and presses against it, the elastic force of the element reacts back to the cigarette pack, further pushing it upwards. The cigarette packs are pressed against the first side of the conveyor belt, thereby limiting their conveying direction through the pressure of the elastic element. That is, the elastic deformation of the spring can be used to adapt and prevent the cigarette packs from deviating or tipping during conveying along the Z-axis, avoiding slippage in the conveying channel. This ensures that the cigarette packs will not deviate during conveying and can only move upward along the Z-axis. Furthermore, the pressure of the elastic element on the cigarette packs slows down the upward movement speed of the pressed cigarette packs along the Z-axis, thus preventing the individual cigarette packs in the conveying channel from sticking together, which is beneficial for subsequent processing and packaging of individual cigarette packs.

[0043] Any feature disclosed in this specification, unless specifically stated otherwise, may be replaced by other equivalent or similar features. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features. Throughout this specification, the same reference numerals indicate the same elements.

[0044] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0045] This embodiment proposes a cigarette pack lifting device that can transfer cigarette packs from a lower position to a higher designated position to facilitate further processing and ensure the continuity of the cigarette pack production process. Furthermore, this cigarette pack lifting device utilizes elastic deformation to adaptively prevent the cigarette packs from shifting or tipping during Z-axis conveying, thus limiting the conveying direction and avoiding slippage within the conveying channel. This ensures that the cigarette packs do not shift during conveying and can only move upwards along the Z-axis. Additionally, it slows down the upward movement rate of the pressed cigarette packs along the Z-axis, providing positioning and diversion functions to prevent mutual adhesion and blockage, which is beneficial for subsequent processing and packaging of individual cigarette packs.

[0046] Specifically, such as Figure 1As shown, the cigarette pack lifting device includes a vertical frame, a conveyor belt 31, a long plate 32, and elastic elements 33. The vertical frame extends along the Z-axis and is fixedly mounted on the ground. The conveyor belt 31 is rotatably mounted within the vertical frame. The long plate 32 extends along the Z-axis, is located within the vertical frame and inside the conveyor belt 31, and forms a conveying channel between the long plate 32 and the first side belt 311 of the conveyor belt 31 along the Y-axis. This conveying channel is used to convey cigarette packs from bottom to top along the Z-axis. Elastic elements 33 are spaced along the Z-axis on the side of the long plate 32 facing the conveying channel. When a cigarette pack is conveyed along the Z-axis to the elastic element 33 and presses against it, the elastic element 33 reacts and presses the cigarette pack against the first side belt 311 of the conveyor belt 31 to guide and decelerate the cigarette pack. Specifically, the conveyor belt 31 can be a conveyor belt.

[0047] Compared to existing technologies, the cigarette pack lifting device in this embodiment features elastic elements 33 on the long plate 32. A conveying channel is formed between the long plate 32 and the first side belt 311 of the conveyor belt 31. This channel conveys the cigarette packs from bottom to top along the Z-axis. Specifically, the cigarette packs are lifted to a designated position by the clamping friction between the conveyor belt 31 and the long plate 32 within the conveying channel. Simultaneously, elastic elements 33 are spaced along the Z-axis on the side of the long plate 32 facing the conveying channel. When a cigarette pack is conveyed along the Z-axis to the elastic element 33 and presses against it, the elastic force of the elastic element 33 reacts back to the cigarette pack. The cigarette pack is pressed against the first side belt 311 of the conveyor belt 31, thereby limiting the conveying direction of the cigarette pack through the pressing action of the elastic element 33. That is, the elastic deformation of the spring can be used to adapt and prevent the cigarette pack from deviating or tipping during the conveying movement along the Z-axis, avoiding the problem of the cigarette pack slipping in the conveying channel. This ensures that the cigarette pack will not deviate in the conveying channel and can only move upward along the Z-axis. Furthermore, due to the pressing action of the elastic element 33 on the cigarette pack, the upward movement speed of the pressed cigarette pack along the Z-axis can be slowed down, thereby ensuring that the individual cigarette packs in the conveying channel are not prone to sticking to each other, which is beneficial for subsequent processing and packaging of individual cigarette packs.

[0048] Furthermore, the elastic deformation of the elastic element 33 directly adapts to prevent the cigarette pack from shifting or tipping during movement, thereby limiting the conveying direction of the cigarette pack in the conveying channel. This enables instantaneous pressure adjustment of the cigarette pack without the need for additional pressure sensors or controllers. The adjustment method is simple, convenient, and has low adjustment costs.

[0049] Furthermore, such as Figure 1As shown, the long plate 32 includes a conveyor plate 321 and a connecting plate 322; wherein, multiple conveyor plates 321 are provided, and the conveyor plates 321 extend along the Z-axis; the connecting plate 322 is used to connect two adjacent conveyor plates 321, and elastic elements 33 are provided at intervals along the Z-axis on the side of the connecting plate 322 facing the conveying channel. In this embodiment, a total of two connecting plates 322 and three conveyor plates 321 are provided.

[0050] By setting multiple conveyor plates 321 and connecting plates 322 that can be combined and connected, on the one hand, compared to setting a single long plate 32, the shorter conveyor plates 321 and connecting plates 322 can be facilitated in transportation and storage; on the other hand, they can be combined and connected to form a long plate 32 of a matching size according to the specific rising position requirements of the tobacco pack on the Z-axis, so as to be suitable for various different rising position requirements of the tobacco pack. Here, the specific number and length of the connecting plates 322 and conveyor plates 321 are not limited, and need to be determined according to the actual rising position requirements of the tobacco pack and the specific layout conditions.

[0051] Specifically, multiple elastic elements 33 are provided on the connecting plate 322. These elastic elements 33 are evenly distributed, forming a relatively uniform adjustment area. When the cigarette pack is conveyed to this adjustment area, the clamping force and speed of the cigarette pack are adjusted by the elastic elements 33 within the adjustment area, thereby better ensuring the adjustment effect of the clamping force and speed of the cigarette pack. The specific number of elastic elements 33 on the connecting plate 322 is not limited here.

[0052] Furthermore, such as Figure 1 As shown, the elastic element 33 includes a flat plate and an arc-shaped plate. The flat plate is adjustablely mounted to the connecting plate 322, allowing the specific mounting position of the elastic element 33 on the connecting plate 322 to be adjusted according to specific needs. One end of the arc-shaped plate is connected to the flat plate, and the other end of the arc-shaped plate is arc-shaped and faces the tobacco pack. The arc-shaped plate is used to guide and cushion the pressure on the tobacco pack. Here, the specific curvature of the arc-shaped plate is not limited, as long as it can ensure that the arc-shaped plate contacts and presses against the tobacco pack.

[0053] By using an arc-shaped plate to guide and cushion the pressure on the cigarette pack, the arc-shaped plate can flexibly contact the cigarette pack, providing a cushioning effect. This reduces the indentations or scratches that the arc-shaped plate may cause to the cigarette pack during the adaptive elastic deformation process, thus better protecting the cigarette pack and not affecting its appearance.

[0054] Specifically, the flat plate and the curved plate are integrated into one structure, which makes the assembly and connection between the flat plate and the curved plate simple and convenient, and makes the processing of the elastic element 33 simple and convenient; in addition, it can ensure the stability of the connection between the flat plate and the curved plate, so as to ensure the working stability and reliability of the entire elastic element 33.

[0055] Furthermore, the flat plate and the curved plate are specifically made of steel that can undergo elastic deformation. That is, the steel material has high elasticity and high wear resistance, so as to avoid wear of the curved plate during repeated pressing with the cigarette pack, thereby making the elastic element 33 suitable for high-frequency pressing action on the cigarette pack.

[0056] Specifically, the distance between the long plate 32 and the first side belt 311 of the conveyor belt 31 along the Y-axis is adjustable to adjust the size of the conveying channel along the Y-axis, thereby making the conveying channel suitable for the upward conveying of cigarette packs of various sizes and improving the applicability and versatility of the entire cigarette pack lifting device.

[0057] Furthermore, such as Figure 1 As shown, the cigarette pack lifting device also includes a U-shaped seat 34 and an adjusting seat 35; wherein, the U-shaped seat 34 is connected to the conveyor plate 321, and the second side belt 312 of the conveyor belt 31 away from the conveying channel passes through the U-shaped seat 34 to avoid the U-shaped seat 34 interfering with the movement of the conveyor belt 31 and to ensure the smooth conveying of the cigarette pack by the conveyor belt 31; one end of the adjusting seat 35 is connected to the outer side of the U-shaped seat 34 away from the second side belt 312, and the other end of the adjusting seat 35 is adjustablely installed on the vertical frame along the Y-axis.

[0058] By enabling the other end of the adjusting seat 35 to be adjustable along the Y-axis and mounted on the vertical frame, the specific setting position of the long plate 32 can be adjusted along the Y-axis. Since the conveyor belt 31 remains stationary along the Y-axis, the position of the long plate 32 inside the conveyor belt 31 is adjustable, thereby adjusting the distance between the long plate 32 and the first side belt 311 of the conveyor belt 31 along the Y-axis, thus making the conveying channel suitable for the upward conveying of cigarette packs of various sizes.

[0059] Specifically, such as Figure 1 As shown, the adjusting seat 35 includes a first plate 351, a second plate 352, and a reinforcing plate 353. The first plate 351 is connected to the outer side of the U-shaped seat 34 away from the second side belt 312. The second plate 352 is vertically connected to the first plate 351 to form an L-shaped structure, allowing the L-shaped adjusting seat 35 to save installation space and ensure a reasonable and compact overall layout. The second plate 352 is adjustable along the Y-axis on the vertical frame to adjust the distance between the long plate 32 along the Y-axis and the first side belt 311 of the conveyor belt 31. The reinforcing plate 353 connects the first plate 351 and the second plate 352 to improve the structural strength of the entire adjusting seat 35. The U-shaped seat 34 and the first plate 351 can be connected by fastening screws, and the first plate 351, the second plate 352, and the reinforcing plate 353 can be a single integrated structure.

[0060] Specifically, a frame seat is installed inside the vertical frame, extending along the Y-axis. The frame seat has M first mounting holes arranged along the Y-axis. The second plate 352 has N second mounting holes, where M > N. A connecting screw is threaded to any aligned first and second mounting holes to allow the second plate 352 to be installed in an adjustable position along the Y-axis on the vertical frame. This makes adjusting the dimensions of the conveying channel along the Y-axis simpler, more convenient, and saves time and effort.

[0061] Furthermore, such as Figure 1 As shown, the cigarette pack lifting device also includes two rollers 36, which are arranged opposite each other in the vertical frame along the Z-axis. The two ends of the conveyor belt 31 are respectively fitted onto the two rollers 36, so that the conveyor belt 31 can be driven to move by the rotation of the rollers 36, so that the conveyor belt 31 can lift the cigarette pack from bottom to top along the conveying channel.

[0062] Specifically, a tensioning wheel is installed in an adjustable position within the vertical frame. The second side belt 312 of the conveyor belt 31, away from the conveying channel, is wound around the tensioning wheel so that the tension of the conveyor belt 31 can be adjusted by the tensioning wheel to ensure that the tension of the conveyor belt 31 is appropriate, thereby further reducing the wear of the conveyor belt 31.

[0063] In this embodiment, the cigarette pack lifting device causes the cigarette pack to contact the elastic element 33 when passing through the connecting plate 322, causing the elastic element 33 to undergo elastic deformation to generate a clamping force. This clamping force can limit the movement position and direction of the cigarette pack, thereby reducing the influence of mechanical vibration on the movement position and direction of the cigarette pack and preventing the cigarette pack from deviating or tipping over during the lifting process. Furthermore, it can slow down the speed of the cigarette pack, so that there is a certain interval between each cigarette pack, thereby achieving the function of positioning and diverting the cigarette pack.

[0064] The cigarette pack lifting device in this embodiment uses an arc-shaped plate to guide the cigarette packs within the conveying channel. This corrects for angular deviations during conveying, better limiting the conveying position and direction of the cigarette packs. The arc-shaped plate flexibly contacts the cigarette packs, providing cushioning and reducing potential indentations or abrasions caused by the plate's adaptive elastic deformation. Furthermore, the arc-shaped plate's elasticity automatically adapts to dimensional tolerances or slight deformations of the cigarette packs, reducing the risk of jamming due to material deviations and ensuring smooth conveying. Simultaneously, the flat and arc-shaped plates absorb vibrations and impacts generated during operation, preventing wrinkles and cracks on the cigarette pack surface, thus better protecting the pack's shape integrity.

[0065] The cigarette pack lifting device in this embodiment allows the position of the long plate 32 inside the conveyor belt 31 to be adjustable, thereby adjusting the distance between the long plate 32 and the first side belt 311 of the conveyor belt 31 along the Y-axis. This makes the conveying channel suitable for cigarette packs of various sizes, and the adjustment method is simple and convenient.

[0066] The cigarette pack lifting device in this embodiment, by setting the aforementioned cooperating long plate 32 and conveyor belt 31, makes the entire cigarette pack lifting device simple in structure, without a complex power structure, and adopts a purely mechanical elastic element 33 structure, with a low failure rate, suitable for long-term continuous operation.

[0067] The cigarette pack lifting device in this embodiment is easy to replace and has low maintenance costs. Furthermore, the elastic element 33 is made of steel that can undergo elastic deformation, ensuring that the elastic element 33 is highly adaptable to temperature changes and dusty environments, and is suitable for high-frequency pressing action on the cigarette pack.

As long as the technical solutions do not conflict with each other, they can be combined arbitrarily. The embodiments formed by the combination are also within the scope of this utility model. Considering the brevity of this article, the embodiments formed by the combination will not be described separately.

[0069] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
