[0001] This utility model relates to the field of tobacco packaging technology, and in particular to a paper stack support device. Background Technology

[0002] In the production process of industries such as tobacco packaging, supporting vertically stacked label paper is a crucial step. Currently, the label paper hoppers commonly used in tobacco packaging equipment face numerous problems when operating at high speeds.

[0003] The paper feed hopper for trademark paper is highly susceptible to displacement due to vibration or external interference during high-speed operation. This displacement leads to unstable paper feeding, severely impacting packaging quality, increasing product defect rates, and raising production costs. Simultaneously, existing support structures also have significant drawbacks, generally exhibiting complex installation requiring substantial manpower and time for setup and debugging; inconvenient adjustment, making it difficult to quickly and accurately adjust to materials of different sizes or specifications; and insufficient vibration resistance, failing to effectively withstand vibrations generated during equipment operation, thus compromising material stability. These shortcomings not only reduce the stability and safety of equipment operation but also limit the improvement of production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a paper stack support device to improve the operational quality and efficiency of the tobacco packaging process and to provide good vibration resistance and support performance.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A paper stack support device is used to support materials stacked vertically. The paper stack support device includes a base, limiting blocks, and several abutment modules. The base supports the materials, and the central axis of the materials passes through the center of the base. The limiting blocks are movably connected to the base and can move closer to or further away from the center of the base in a horizontal plane. The number of limiting blocks is the same as the number of corners of the materials, and each limiting block is used to limit one corner of the materials. All the abutment modules are distributed at intervals in the vertical direction. Each abutment module includes several pairs of abutment members. Each pair of abutment members is symmetrical about the central axis of the materials. The abutment members can move closer to or further away from the materials. Each abutment member includes a body and a buffer ring. The buffer ring is selectively rotatably connected to the body and can rotate around its own axis. The axis of the buffer ring is parallel to the horizontal plane, and the side of the buffer ring can abut against the side of the materials.

[0007] As an optional technical solution for the paper stack support device, the abutment also includes a rotating bearing, the inner ring of which is fixed relative to the main body of the component, the buffer ring is sleeved on the outer ring of the rotating bearing, and the rotating bearing and the buffer ring are coaxial.

[0008] As an optional technical solution for the paper stack support device, the abutment further includes a pad and a tightening bolt. The screw of the tightening bolt passes through the inner ring of the rotating bearing and is screwed to the main body of the component, so that the head of the tightening bolt can move closer to or further away from the main body of the component along the axis of the tightening bolt, and the axis of the tightening bolt is parallel to the horizontal plane. The screw of the tightening bolt passes through the pad, and the pad is disposed between the head of the tightening bolt and the rotating bearing. The head of the tightening bolt can push the pad to press against the outer ring of the rotating bearing, so that the relative position of the buffer ring and the main body of the component is fixed.

[0009] As an optional technical solution for the paper stack support device, the material is rectangular, and the inner side of the limiting block forms an L-shaped limiting surface, which is used to abut against and limit the two adjacent sides at the top corner of the material.

[0010] As an optional technical solution for the paper stack support device, the abutment module also includes several connecting rods, the number of connecting rods being the same as the number of sides of the material, and each connecting rod having at least one abutment member, the connecting rod being able to drive the abutment member to move.

[0011] As an optional technical solution for the paper stack support device, the abutment module further includes a first driving unit, which is used to drive the connecting rod to move closer to or away from the material.

[0012] As an optional technical solution for the paper stack support device, the abutment module further includes a second drive unit, which is used to drive all the connecting rods in the abutment module to move in the vertical direction.

[0013] As an optional technical solution for the paper stack support device, the abutment also includes at least one mounting pin, and the main body of the abutment is detachably connected to the connecting rod through the mounting pin.

[0015] As an optional technical solution for the paper stack support device, the buffer ring is made of an elastic material.

[0016] The beneficial effects of this utility model are:

[0017] This paper stack support device features a design where the material's central axis passes through the center of the base, forming a centrally symmetrical support system. This effectively disperses the gravity distribution of the stacked materials, ensuring balanced force distribution, improving support stability, and preventing tilting or displacement caused by unilateral stress concentration. Combined with the symmetrical distribution of limiting blocks, a three-dimensional positioning constraint system is formed. The horizontally adjustable limiting blocks can be adjusted in the horizontal plane to adapt to the corner positioning requirements of materials of different sizes, achieving material center positioning and synchronous corner limiting, significantly improving equipment compatibility. The symmetrically arranged abutment components in the abutment modules can be independently adjusted, achieving multi-directional flexible contact with the sides of the material, providing stable physical support, avoiding material displacement caused by unilateral force, and ensuring the material remains stable and does not shift. This improves the operational stability of the paper stack support device; the multi-level abutment modules form a three-dimensional constraint network, and the vertically distributed abutment modules provide multi-level support. Meanwhile, the rotatable design of the buffer ring replaces sliding friction with rolling friction on the material contact surface, dynamically adapting to material surface deformation. The buffer ring absorbs vibration, forming a dynamic friction compensation mechanism, reducing surface scratches, extending the service life of the paper stack support device, and ensuring operational safety. The buffer ring's rotation around a horizontal axis ensures the contact surface between the material and the abutment module is always in a state of rolling friction, achieving adaptive buffer protection. The selective rotation connection mechanism allows operators to choose to activate or lock the buffer ring based on the material properties or the load requirements of the base, accommodating the support needs of materials with varying hardness. Through these limitations, the paper stack support device achieves multi-dimensional positioning and adaptive adjustment, reducing the difficulty of debugging and maintenance.

[0028] The embodiments of this utility model are described in detail below.

[0029] like Figure 1 and Figure 2As shown, this embodiment provides a paper stack support device for supporting materials stacked vertically. The paper stack support device includes a base 400, a limiting block 300, and several abutment modules. The base 400 is used to carry the materials, and the central axis of the materials passes through the center of the base 400. The limiting block 300 is movably connected to the base 400 and can approach or move away from the center of the base 400 in a horizontal plane. The number of limiting blocks 300 is the same as the number of corners of the materials, and each limiting block 300 is used to limit one corner of the materials. All the abutment modules are distributed at intervals in the vertical direction. Each abutment module includes several pairs of abutment members 100. Each pair of abutment members 100 is symmetrical about the central axis of the materials. The abutment members 100 can approach or move away from the materials. Each abutment member 100 includes a body 110 and a buffer ring 150. The buffer ring 150 is selectively rotatably connected to the body 110 and can rotate around its own axis. The axis of the buffer ring 150 is parallel to the horizontal plane, and the side of the buffer ring 150 can abut against the side of the materials.

[0030] This paper stack support device features a design where the material's central axis passes through the center of the base 400, forming a centrally symmetrical support system. This effectively disperses the gravity distribution of the stacked materials, ensuring balanced force distribution, improving support stability, and preventing tilting or displacement caused by unilateral stress concentration. Combined with the symmetrical distribution of the limiting blocks 300, a three-dimensional positioning constraint system is formed. The horizontally adjustable limiting blocks 300 can be adjusted in the horizontal plane to adapt to the corner positioning requirements of materials of different sizes, achieving material center positioning and synchronous corner limiting, significantly improving equipment compatibility. The symmetrically arranged abutment components 100 in the abutment module can be independently adjusted, achieving multi-directional flexible contact with the sides of the material, providing stable physical support, avoiding material displacement caused by unilateral force, and ensuring the material remains stable and does not shift. This improves the operational stability of the paper stack support device; the multi-level abutment modules form a three-dimensional constraint network, and the vertically distributed abutment modules provide multi-level support. Meanwhile, the rotatable design of the buffer ring 150 allows rolling friction to replace sliding friction on the material contact surface, dynamically adapting to material surface deformation. The buffer ring 150 absorbs vibration, forming a dynamic friction compensation mechanism that reduces surface scratches, extends the service life of the paper stack support device, and ensures operational safety. The characteristic of the buffer ring 150 rotating around a horizontal axis ensures that the contact surface between the material and the abutment module is always in a state of rolling friction, achieving adaptive buffer protection. The selective rotation connection mechanism allows operators to choose to activate or lock the buffer ring 150 according to the material properties or the load requirements of the base 400, accommodating the support needs of materials with different hardness. Through these limitations, the paper stack support device achieves multi-dimensional positioning and adaptive adjustment, reducing the difficulty of debugging and maintenance.

[0031] Specifically, the material is an FXS796 brand paper hopper. The paper stack support device is used to provide safe and reliable adjustable support for the paper hopper while ensuring efficient storage.

[0032] In this embodiment, the base 400 is made of high-strength metal material.

[0033] In this embodiment, the abutment 100 also includes a rotating bearing 120. The inner ring of the rotating bearing 120 is fixed relative to the main body 110. The buffer ring 150 is sleeved on the outer ring of the rotating bearing 120. The rotating bearing 120 and the buffer ring 150 are coaxial.

[0034] The rotating bearing 120 enables low-resistance rotation between the buffer ring 150 and the main body 110. When the material undergoes micro-displacement, the buffer ring 150 eliminates sudden changes in static friction through its rotation, preventing surface damage caused by a sudden increase in instantaneous frictional resistance, reducing contact surface friction loss, achieving precise friction control, and extending the service life of the buffer ring 150. The modular structure design of the outer ring and the buffer ring 150 allows for fine adjustment of the contact angle when the material is subjected to external forces, adapting to different working conditions. Simultaneously, these improvements help to disperse and transmit vibration energy along the bearing raceway, avoiding unnecessary rotation caused by multi-directional vibration and enhancing vibration resistance.

[0035] Furthermore, the abutment 100 also includes a pad 130 and a tightening bolt 140. The screw of the tightening bolt 140 passes through the inner ring of the rotating bearing 120 and is screwed to the main body 110, so that the head of the tightening bolt 140 can move closer to or further away from the main body 110 along the axis of the tightening bolt 140. The axis of the tightening bolt 140 is parallel to the horizontal plane. The screw of the tightening bolt 140 passes through the pad 130, and the pad 130 is located between the head of the tightening bolt 140 and the rotating bearing 120. The head of the tightening bolt 140 can push the pad 130 to press against the outer ring of the rotating bearing 120, so that the relative position of the buffer ring 150 and the main body 110 is fixed.

[0036] The tightening bolt 140 applies axial pressure through the pad 130, precisely controlling the clamping force of the pad 130 on the outer ring of the rotating bearing 120. This allows for gradient adjustment of the rotational damping of the buffer ring 150, achieving the purpose of locking or unlocking the buffer ring 150. This improvement enables wear compensation and extends the service life of key components. Specifically, the mechanical amplification effect of the screw head pushing the pad 130 ensures a uniformly distributed clamping force on the outer ring of the rotating bearing 120, eliminating the off-center load problem caused by traditional single-point clamping, preventing rotational jamming caused by local deformation of the bearing outer ring, and improving the positioning accuracy of the buffer ring 150. The tightening bolt 140 uses a screw adjustment method, providing linear pressure control and avoiding bearing jamming caused by overtightening. This design allows for switching of the buffer ring 150's operating mode using only the tightening bolt 140, and millimeter-level gap control through axial adjustment, meeting the fine-tuning requirements of the paper stack support device and significantly improving adjustment efficiency.

[0037] In this embodiment, the material is rectangular, and an L-shaped limiting surface is formed on the inner side of the limiting block 300. The L-shaped limiting surface is used to abut against and limit the two adjacent sides at the top corner of the material.

[0038] The L-shaped limiting surface forms a double-sided contact limiting mechanism with the top corner of the material in a horizontal plane, preventing the material from rotating or shifting. At the same time, the top corner of the rectangular material and the L-shaped limiting surface form a three-dimensional constraint, which has self-guiding characteristics, shortening the initial positioning time when the material is stacked, helping to achieve rapid alignment, and also effectively preventing the rectangular material from rotating or shifting.

[0039] For example, the abutment module also includes a plurality of connecting rods 200, the number of connecting rods 200 being the same as the number of sides of the material, and each connecting rod 200 having at least one abutment member 100, the connecting rod 200 being able to drive the abutment member 100 to move.

[0040] The number of connecting rods 200 matches the number of sides of the material, allowing for expansion to polygonal material support scenarios and providing strong adaptability. It ensures a balanced distribution of constraint forces in all directions. Multiple abutment members 100 can be set on the connecting rods 200, facilitating synchronous movement of these members and ensuring balanced symmetrical force application.

[0041] Furthermore, the abutment module also includes a first drive unit, which is used to drive the connecting rod 200 to approach or move away from the material.

[0042] The first drive unit enables fine adjustment of the abutment 100 in the horizontal plane to control the abutment 100 to start or stop supporting the material, and also helps to respond to changes in the size of the material.

[0043] Furthermore, the abutment module also includes a second drive unit, which is used to drive all the connecting rods 200 in the abutment module to move vertically.

[0044] The second drive unit adjusts the vertical position of all connecting rods 200 in the abutment module to achieve stepless adjustment of the support height, matching the support requirements of different stacking heights and providing support for specific height sections of the material pile to adapt to changes in working conditions with different stacking layers. This improvement enables the overall vertical displacement of the abutment module, ensuring balanced support force.

[0045] The design of using a first drive unit and a second drive unit can replace manual adjustment by operators, thereby meeting the real-time adjustment needs of automated production lines.

[0046] Furthermore, the abutment 100 also includes at least one mounting pin 160, and the main body 110 is detachably connected to the connecting rod 200 via the mounting pin 160. Specifically, the mounting pin 160 is a bolt.

[0047] The quick-assembly and disassembly structure allows for reconfigurable angles of the abutment component 100, enabling adjustments to its density based on material dimensions to adapt to different working conditions and meet the support requirements of irregularly shaped materials. The standardized interface design of the mounting pin 160 shortens the assembly and disassembly time of the abutment component 100, facilitating the replacement of damaged parts, improving maintenance convenience, and ensuring reduced positional accuracy errors during repeated installations. Furthermore, damage to a single abutment component 100 can be quickly replaced by disassembling the mounting pin 160, avoiding the maintenance losses required by traditional integrated structures that necessitate complete machine downtime.

[0048] In this embodiment, the base 400 is provided with a slide rail 401, and the number of slide rails 401 and the number of limiting blocks 300 are the same. Each limiting block 300 is slidably engaged with a slide rail 401.

[0049] The guide structure of slide rail 401 ensures the accuracy of the movement trajectory of limit block 300, ensuring that limit block 300 can move relative to base 400 as expected, which helps to maintain positioning stability.

[0050] For example, the buffer ring 150 is made of an elastic material.

[0051] Elastic materials can absorb impact energy through deformation, preventing material rebound caused by rigid collisions. At the same time, the micro-textured design of the elastomer surface helps increase the coefficient of friction, which can prevent material slippage while reducing vibration.

[0052] In this embodiment, the buffer ring 150 is made of rubber. In other embodiments of this embodiment, the buffer ring 150 is made of other elastic materials. The selection of the material of the buffer ring 150 is determined by those skilled in the art based on actual engineering conditions, and the method of determination is common knowledge in the art, and will not be elaborated here.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
