Description

Technical Field

[0001] This utility model relates to the technical field of material storage devices, specifically to a storage rack for storing large rolls of materials. Background Technology

[0002] In modern industrial production and warehousing logistics, the storage and transfer of large rolls of materials is a crucial link. To achieve efficient and orderly material management, specialized large roll storage racks are typically used to centrally store large rolls of materials. These racks generally include a support structure made of a metal frame, with support rollers on both sides to support the weight of the large rolls and allow them to rotate to a limited extent under gravity or external thrust to meet subsequent loading or unloading needs.

[0003] However, with long-term operation and increased service life, large roll storage racks inevitably face problems such as structural aging, support frame deformation, roller axis misalignment, and bearing wear. In particular, the bearings of the support roller system are prone to increased rotational resistance, jamming, or asynchronous rotation under long-term high load and low maintenance conditions, causing the large rolls of material to be unable to rotate or move normally on the storage rack, resulting in a "jamming" phenomenon.

[0004] When large rolls of material become jammed during operation, operators typically need to apply manual force to push or pull them to forcibly release the obstruction. This method carries significant safety risks. Because large rolls of material are usually enormous in size and weight (reaching several tons or even tens of tons), they possess considerable inertia and a high center of gravity. During manual pushing, slippage, tipping, or detachment from the support frame are highly likely to occur. Such accidents can not only damage equipment and render the material unusable, but also cause serious or even fatal personal injuries to nearby workers, such as being crushed or impacted. Furthermore, manual intervention lacks precise control over force and direction, potentially causing secondary damage to the equipment structure, further expanding the scope of the malfunction, and increasing maintenance costs and downtime.

[0005] Therefore, the existing technology still needs further development. Utility Model Content

[0006] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a storage rack for storing large rolls of materials, so as to solve the technical problem in the prior art that when large rolls of materials roll on the storage rack and get stuck in the running position, operators need to apply manual external force to push and pull to forcibly release the jam.

[0007] To achieve the above-mentioned technical objectives, according to one aspect of the present invention: a storage rack for storing large rolls of material is provided, comprising: a support frame and two pushing components. The support frame is used to support the large roll of material. The support frame is provided with a guide channel extending along a first preset direction. The guide channel is used to accommodate at least a portion of the large roll of material and guide the large roll of material to roll along the extension direction of the guide channel. The two pushing components are movably disposed on the support frame along the first preset direction, and the two pushing components are respectively located on opposite sides of the guide channel. The pushing parts of the two pushing components are respectively used to abut against both ends of the large roll of material, so as to synchronously push the large roll of material to roll towards the target position along the extension direction of the guide channel through the two pushing components.

[0008] Further, the pushing component includes: a movable plate, which is movably mounted on the support frame along a first preset direction; and a pushing arm, which is swingably mounted on the movable plate to drive the pushing arm to move along the first preset direction via the movable plate; the pushing arm has a avoidance posture for avoiding a large roll of material and a pushing posture for pushing the large roll of material; wherein, when it is necessary to move the pushing arm from the side of the target large roll of material close to the target position to the side of the target large roll of material away from the target position, the movable plate drives the pushing arm to move toward the side of the target large roll of material away from the target position, so that when the pushing arm contacts the target large roll of material, the pushing arm swings toward the direction away from the target large roll of material, so that the pushing arm is in the avoidance posture; after the pushing arm moves to the side of the target large roll of material away from the target position, the pushing arm returns from the avoidance posture to the pushing posture.

[0009] Furthermore, the pushing component also includes: a first support plate and a second support plate, which are spaced apart on the moving plate along the width direction; a connecting shaft extending along the width direction of the moving plate, located between the first and second support plates, with both ends of the connecting shaft fixedly connected to the first and second support plates respectively; a connecting end of the pushing arm rotatably sleeved on the connecting shaft; a mounting groove provided on the connecting end of the pushing arm; and an elastic reset member sleeved on the connecting shaft, with at least a portion of the elastic reset member located within the mounting groove, the connecting end of the elastic reset member connected to the moving plate, and the reset end of the elastic reset member connected to the pushing arm, so as to drive the pushing arm to return to the pushing posture through the elastic reset member.

[0010] Furthermore, the storage rack also includes a driving component, which is drivenly connected to two pushing components to drive the two pushing components to move synchronously along a first preset direction.

[0011] Furthermore, the storage rack also includes: a first transmission component, which has a first power input and a first transmission output. The first power input is connected to a drive component and is also connected to the first transmission output. The drive component drives the first transmission output to move via the first power input. Two second transmission components are arranged correspondingly to two push components. Each second transmission component has a second power input and a second transmission output. Each second power input is connected to the first transmission output to drive the second power input to move synchronously. Each second power input is connected to its corresponding second transmission output and is connected to its corresponding push component. Each second power input drives its corresponding push component to reciprocate along a first preset direction via its corresponding second transmission output.

[0012] Further, the first transmission component includes: a first main sprocket, which is connected to the drive end of the drive component to drive the first main sprocket to rotate; a first driven sprocket and a first transmission chain, wherein the first driven sprocket is rotatably disposed, and the first transmission chain is sleeved on the first main sprocket and the first driven sprocket, and the first main sprocket drives the first driven sprocket to rotate via the first transmission chain; a transmission shaft, which extends along a second preset direction and is rotatably disposed, wherein the first driven sprocket is sleeved on the transmission shaft and is relatively fixedly connected to the transmission shaft to drive the transmission shaft to rotate via the first driven sprocket; wherein the first preset direction is perpendicular to the second preset direction; the first main sprocket forms a first power input part, and the transmission shaft forms a first transmission output part.

[0013] Furthermore, the storage rack also includes: a first support base and a second support base, the first support base and the second support base are disposed on an installation reference, and the first support base and the second support base are spaced apart along a second preset direction; the drive shaft is located between the first support base and the second support base, and the two ends of the drive shaft are rotatably disposed on the first support base and the second support base respectively.

[0014] Further, the second transmission component includes: a second main sprocket, which is connected to the first transmission output unit to drive the second main sprocket to rotate via the first transmission output unit; the second main sprocket forms a second power input unit; two second driven sprockets, which are rotatably mounted on the support frame, spaced apart along a first preset direction, and whose axes are located in the same horizontal plane; a second transmission chain, which is sleeved on the second main sprocket and the two second driven sprockets, and a pushing component is mounted on the bearing section of the second transmission chain, which drives the pushing component to reciprocate along the first preset direction via the second transmission chain; the second transmission chain forms a second transmission output unit.

[0015] Furthermore, the storage rack also includes: two chain guide bars, both of which extend along a first preset direction. The two chain guide bars are disposed on the support frame and are located on opposite sides of the guide channel. The two chain guide bars are disposed one-to-one with the two second transmission components. The chain guide bars are located between the corresponding two second driven sprockets and below the load-bearing section of the corresponding second transmission chain. The chain guide bars are used to support and guide the load-bearing section of the second transmission chain.

[0016] Furthermore, the storage rack also includes: two sets of tensioning components, each set of tensioning components being arranged in a one-to-one correspondence with two second transmission components; each set of tensioning components having at least one tensioning assembly; the tensioning assembly having a movable part, the movable part being movably disposed on the support frame relative to the support frame body along a first preset direction; one of the two second driven sprockets being rotatably disposed on the movable part, so as to drive the corresponding second driven sprocket to move along the first preset direction by moving the movable part, thereby adjusting the tension of the second transmission chain.

[0017] Beneficial effects: Applying the technical solution of this utility model, the storage rack for storing large rolls of materials provided by this utility model includes a support frame and two pushing components. The support frame supports the large roll of materials, and when the large roll of materials is placed on the support frame, it is rotatably positioned relative to the support frame. The support frame is provided with a guide channel extending along a first preset direction, which accommodates at least a portion of the large roll of materials and guides the large roll of materials to roll along the extension direction of the guide channel. The pushing components are movably disposed on the support frame along the first preset direction and are located on one side of the guide channel. The two pushing components are movably disposed on the support frame along the first preset direction and are located on opposite sides of the guide channel. When it is necessary to roll the large roll of materials to the target position, the two pushing components move synchronously along the first preset direction, so that the pushing parts of the two pushing components abut against the two ends of the large roll of materials, and as the two pushing components continue to move, they push the large roll of materials to roll towards the target position along the extension direction of the guide channel.

[0018] Therefore, when the large roll of material rolls rolls towards the target position along the extension direction of the guide channel and gets stuck, two pushing components located on opposite sides of the guide channel simultaneously apply thrust to both ends of the large roll, effectively overcoming rolling resistance and automatically releasing the stuck state. This process eliminates the need for operators to approach or manually push or pull, fundamentally avoiding safety accidents caused by improper manual force application and effectively ensuring the personal safety of operators. Simultaneously, the two pushing components act synchronously on both ends of the large roll from opposite sides of the guide channel, ensuring uniform and symmetrical thrust distribution, thus effectively preventing the large roll from tilting, twisting, or interfering with the support frame due to unilateral force. This symmetrical and controllable pushing method not only helps to smoothly and efficiently release the stuck state but also effectively avoids secondary jamming or equipment damage during the release process. Furthermore, by replacing manual operation with automated pushing, the reliability and continuity of the large roll displacement process are significantly improved. The system can stably and efficiently push large rolls of material to the target position, significantly reducing downtime caused by jamming and improving overall operational efficiency and the automation level of the production line. Furthermore, by providing guide channels extending along a first preset direction on the support frame, a clear and stable rolling path is provided for the large rolls of material, ensuring that they can roll smoothly and steadily to the target position. This storage rack for storing large rolls of material effectively solves the technical problem in existing technologies where, when large rolls of material rolls roll on the storage rack and become jammed in the operating position, operators need to apply manual force to push or pull them to forcibly release the jamming.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] Please see Figures 1 to 7According to an embodiment of the present invention, a storage rack for storing large rolls of material is provided, comprising: a support frame 1 and two pushing components 2. The support frame 1 is used to support the large roll of material 100, and the large roll of material 100 is rotatably disposed relative to the support frame 1. The support frame 1 is provided with a guide channel 10 extending along a first preset direction. The guide channel 10 is used to accommodate at least a portion of the large roll of material 100 and guide the large roll of material 100 to roll along the extension direction of the guide channel 10. The two pushing components 2 are movably disposed on the support frame 1 along the first preset direction, and the two pushing components 2 are respectively located on opposite sides of the guide channel 10. The pushing parts of the two pushing components 2 are respectively used to abut against both ends of the large roll of material 100, so that the two pushing components 2 synchronously push the large roll of material 100 to roll towards the target position along the extension direction of the guide channel 10.

[0023] As can be seen, the storage rack for storing large rolls of materials provided by this utility model includes a support frame 1 and two pushing components 2. The support frame 1 is used to support the large roll of materials 100. When the large roll of materials 100 is placed on the support frame 1, the large roll of materials 100 is rotatably arranged relative to the support frame 1. The support frame 1 is provided with a guide channel 10 extending along a first preset direction. The guide channel 10 is used to accommodate at least a portion of the large roll of materials 100 and guide the large roll of materials 100 to roll along the extension direction of the guide channel 10. The pushing component 2 is movably disposed on the support frame 1 along the first preset direction, and the pushing component 2 is located on one side of the guide channel 10; two pushing components 2 are movably disposed on the support frame 1 along the first preset direction, and the two pushing components 2 are respectively located on opposite sides of the guide channel 10; when it is necessary to roll the large roll of material 100 to the target position, the two pushing components 2 move synchronously along the first preset direction, so that the pushing parts of the two pushing components 2 respectively abut against the two ends of the large roll of material 100, and as the two pushing components 2 continue to move, the large roll of material 100 is pushed to roll towards the target position along the extension direction of the guide channel 10.

[0024] Therefore, when the large roll of material 100 rolls along the extension direction of the guide channel 10 towards the target position and gets stuck, the two pushing components 2 located on opposite sides of the guide channel 10 simultaneously apply thrust to both ends of the large roll of material 100, effectively overcoming rolling resistance and automatically releasing the stuck state. This process does not require operators to approach or manually push or pull, fundamentally avoiding safety accidents caused by improper manual force application and effectively protecting the personal safety of operators. At the same time, the two pushing components 2 act synchronously on both ends of the large roll of material 100 from opposite sides of the guide channel 10, ensuring uniform and symmetrical thrust distribution, thereby effectively preventing the large roll of material 100 from tilting, twisting, or causing new interference with the support frame 1 due to unilateral force. This symmetrical and controllable pushing method not only helps to smoothly and efficiently release the stuck state but also effectively avoids secondary jamming or equipment damage during the release process. Furthermore, by replacing manual operation with automated pushing, the reliability and continuity of the displacement process of the large roll of material 100 are significantly improved. The system can stably and efficiently push the large material roll 100 to the target position, significantly reducing downtime caused by jamming and improving overall operational efficiency and the automation level of the production line. Furthermore, by providing a guide channel 10 extending along a first preset direction on the support frame 1, a clear and stable rolling path is provided for the large material roll 100, ensuring that the large material roll can roll smoothly and steadily to the target position. This storage rack for storing large material rolls effectively solves the technical problem in the prior art where, when a large material roll rolls are rolling on the storage rack and jammed in the operating position, operators need to apply manual external force to push or pull to forcibly release the jam.

[0025] The target position refers to the preset or designated position to which the material roll 100 needs to be moved on the support frame 1. The target position can be a storage location for placing the target material roll or a pre-set unloading position.

[0026] Among them, such as Figure 1 As shown, the direction indicated by arrow A is the first preset direction, which can be understood as the length direction of the support frame 1.

[0027] Furthermore, such as Figure 6As shown, the support frame 1 is provided with two support rails 11, both of which extend along a first preset direction and are respectively located on opposite sides of the support frame 1, forming a guide channel 10 between them. The material roll 100 has rotating wheels 101 at both ends, rotatably mounted on the two support rails 11. When the material roll 100 is placed on the support frame 1, the rotating wheels 101 at both ends of the material roll 100 are supported on the corresponding support rails 11, and a portion of the material roll 100 is located within the guide channel 10. Therefore, when a pushing force is applied to the material roll 100, the rotating wheels 101 at both ends of the material roll 100 roll smoothly along the support rails 11, enabling the material roll 100 to move along the extension direction of the guide channel 10.

[0028] Furthermore, each rotating wheel 101 has an annular limiting groove on its surface. When the large roll of material 100 is placed on the support frame 1, at least a portion of each support guide rail 11 is embedded in the corresponding annular limiting groove, thereby achieving rolling contact between the rotating wheel 101 and the support guide rail 11. By setting annular limiting grooves on the rotating wheel 101 and embedding at least a portion of the support guide rail 11 within them, not only is smooth rolling of the large roll of material 100 achieved, but a reliable lateral limiting function is also provided, effectively preventing the rotating wheel 101 from disengaging from the support guide rail 11, significantly improving the safety and stability of the equipment operation.

[0029] Furthermore, the support frame 1 is set on the installation reference.

[0030] Specifically, such as Figure 4 and Figure 7 As shown, the pushing component 2 includes: a movable plate 21, which is movably mounted on the support frame 1 along a first preset direction; and a pushing arm 22, which is swingably mounted on the movable plate 21 so as to drive the pushing arm 22 to move along the first preset direction via the movable plate 21; the pushing arm 22 has a avoidance posture for avoiding the large roll of material 100 and a pushing posture for pushing the large roll of material 100; wherein, when it is necessary to move the pushing arm 22 from the side of the target large roll close to the target position to the side of the target large roll away from the target position, the movable plate 21 drives the pushing arm 22 to move toward the side of the target large roll away from the target, so that when the pushing arm 22 contacts the target large roll, the pushing arm 22 swings toward the direction away from the target large roll, so that the pushing arm 22 is in the avoidance posture; after the pushing arm 22 moves to the side of the target large roll away from the target position, the pushing arm 22 returns from the avoidance posture to the pushing posture.

[0031] With the above-described structure, the movable plate 21 drives the push arm 22 to reciprocate along a first preset direction, thereby sequentially pushing the various material rolls 100 stored on the support frame 1. Simultaneously, the push arm 22 is swayably mounted on the movable plate 21. When the push arm 22 needs to be moved from the side of the target material roll closest to the target position to the side furthest from the target position in preparation for the next push, as the movable plate 21 moves, after the push arm 22 contacts the target material roll, under the reaction force exerted by the target material roll, the push arm 22 automatically swings away from the target material roll, entering an avoidance posture. This design effectively avoids collisions or jamming between the push arm 22 and the target material roll, allowing it to smoothly bypass the target material roll. Therefore, the above structure not only prevents equipment damage or material displacement caused by rigid collisions but also eliminates the need for manual intervention during the return process, significantly improving operational safety and automated operation efficiency.

[0032] Optionally, when the first material roll 100 is pushed to the target position, the push arm 22 is in a pushing posture, and the position of the push arm 22 is on the side of the next material roll to be pushed (i.e., the next target material roll) closer to the target position. When it is necessary to prepare to push the next target material roll, the push arm 22 needs to be moved from the side of the target material roll closer to the target position to the side of the target material roll farther away from the target position.

[0033] At this time, the moving plate 21 drives the pushing arm 22 to move along the first preset direction toward the side of the target material roll away from the target position. As the moving plate 21 moves, the pushing arm 22 will come into contact with the side of the target material roll that is close to the target position. Under the action of the reaction force applied by the target material roll, the pushing arm 22 will automatically swing toward the direction away from the target material roll, thereby causing the pushing arm 22 to enter the avoidance posture (at this time, the pushing arm 22 is located below the target material roll or close to its side), thus realizing non-interference obstacle crossing with the target material roll.

[0034] When the moving plate 21 continues to drive the pushing arm 22 to move to the side of the target material roll away from the target position, and the pushing arm 22 disengages from the target material roll, the pushing arm 22 returns from the avoidance posture to the pushing posture, ready to apply thrust to the next target material roll, thus realizing a continuous and automatic pushing cycle.

[0035] The "avoidance posture" mentioned above refers to the push arm 22 actively or passively deviating from its normal position to avoid the large roll of material, preventing collisions or interference, and thus achieving a smooth movement from one side of the large roll of material to the other. When the push arm 22 is in the avoidance posture, under the reaction force exerted by the large roll of material, the push arm 22 swings towards the moving plate 21 (i.e., swings downwards), so that it passes under or close to the side of the large roll of material. As the moving plate 21 continues to move, the push arm 22 can thus complete the obstacle-crossing action of the large roll of material and achieve an unobstructed return.

[0036] The "pushing posture" mentioned above refers to the state in which the pushing arm 22 is in its normal operating position, able to directly contact the large roll of material and apply thrust to move the large roll of material towards the target position. When the pushing arm 22 is in the pushing posture, it is vertically mounted on the moving plate 21 or slightly tilted forward towards the side of the large roll of material. At this time, the connection structure between the pushing arm 22 and the moving plate remains stable and has sufficient rigidity to effectively transmit the thrust. Thus, during the pushing phase, the pushing arm 22 contacts the large roll of material in this posture and moves forward synchronously with the moving plate 21, achieving a smooth and reliable pushing of the large roll of material.

[0037] Specifically, such as Figure 4 and Figure 7 As shown, the pushing component 2 further includes: a first support plate 23 and a second support plate 24, which are spaced apart on the moving plate 21 along the width direction of the moving plate 21; a connecting shaft 25 extending along the width direction of the moving plate 21, located between the first support plate 23 and the second support plate 24, with both ends of the connecting shaft 25 fixedly connected to the first support plate 23 and the second support plate 24 respectively; the connecting end of the pushing arm 22 is rotatably sleeved on the connecting shaft 25; a mounting groove 220 is provided on the connecting end of the pushing arm 22; and an elastic reset member 26, which is sleeved on the connecting shaft 25, with at least a portion of the elastic reset member 26 located within the mounting groove 220. The connecting end of the elastic reset member 26 is connected to the moving plate 21, and the reset end of the elastic reset member 26 is connected to the pushing arm 22, so that the pushing arm 22 can be driven to return to the pushing posture through the elastic reset member 26.

[0038] With the above-described structure, the push arm 22 is rotatably mounted on the connecting shaft 25 fixed between the first support plate 23 and the second support plate 24 via its connecting end, thus forming a stable hinge structure. This design allows the push arm 22 to swing smoothly around the connecting shaft 25, flexibly switching between avoidance and push postures, while ensuring structural stability and repeatability of motion during the swing process. Meanwhile, an elastic reset member 26 is mounted on the connecting shaft 25, with one end connected to the moving plate 21 and the other end connected to the push arm 22, and at least partially located within the mounting groove 220 at the connecting end of the push arm 22. When the push arm 22 swings into the avoidance posture due to contact with the large roll of material 100, the elastic reset member 26 is compressed or twisted, thereby storing elastic potential energy; when the push arm 22 disengages from contact, the elastic reset member 26 releases energy, automatically driving the push arm 22 back to the push posture. This reset process requires no external control or manual intervention, ensuring reliable execution of the next pushing action and achieving continuous, efficient, and automated cyclic operation. Furthermore, the elastic reset element 26 provides a continuous and controllable reset force, enabling the push arm 22 to quickly return to its original position after disengagement, effectively improving the dynamic response performance of the mechanism. Simultaneously, by adjusting the stiffness of the elastic reset element 26, it can accommodate material rolls 100 of different weights or rolling resistances, enhancing the equipment's versatility and adaptability to various operating conditions. In addition, the connecting shaft 25 and the elastic reset element 26 are integrated between the first and second support plates, and the elastic reset element 26 is partially housed within the mounting groove 220 of the push arm 22, making full use of local space. The overall structure is compact, effectively reducing the external space occupied by the mechanism and facilitating installation and maintenance within limited space.

[0039] Optionally, the elastic reset element 26 is a torque spring.

[0040] Among them, such as Figure 7 As shown, arrow B points in the direction of the width of the movable plate 21.

[0041] Specifically, such as Figure 1 , Figure 2 and Figure 5As shown, the storage rack also includes a drive component 3, which is driven by two push components 2 to drive the two push components 2 to move synchronously along a first preset direction. With this structural arrangement, the drive component 3 simultaneously drives the two push components 2, located on opposite sides of the guide channel 10, to move synchronously, so that they push both ends of the large material roll 100 at the same speed and stroke. This synchronous pushing method effectively avoids the material roll from tilting, twisting, or jamming due to unilateral force or inconsistent pushing stroke, ensuring its straight and smooth rolling along the guide channel, significantly improving the stability and reliability of the pushing process. At the same time, by uniformly controlling the movement of the two push components 2 through a single drive source (drive component 3), the control delay or asynchronous action problems that may occur in multi-drive systems are reduced, ensuring the consistency and repeatability of the pushing action, thereby improving the positioning accuracy of the large material roll 100 reaching the target position and meeting the high-precision positioning requirements of automated production lines. In addition, the dual-side synchronous drive ensures that the thrust is applied evenly to both ends of the material roll 100, avoiding local stress concentration, reducing the risk of damage to the end face of the material roll 100 and the structure of the pushing component 2, extending the service life of the equipment, and protecting the integrity of the material.

[0042] Specifically, such as Figure 2 and Figure 6 As shown, the storage rack further includes: a first transmission component 4, which has a first power input and a first transmission output. The first power input is connected to the drive component 3 and is also connected to the first transmission output. The drive component 3 drives the first transmission output to move through the first power input; two second transmission components 5, which are arranged one-to-one with two push components 2; each second transmission component 5 has a second power input and a second transmission output. Each second power input is connected to the first transmission output so that it drives each second power input to move synchronously through the first transmission output; each second power input is connected to its corresponding second transmission output and is connected to its corresponding push component 2. Each second power input drives its corresponding push component 2 to reciprocate along a first preset direction through its corresponding second transmission output.

[0043] With this structural configuration, the power of the drive component 3 is transmitted through the first power input section of the first transmission component 4, which drives the first transmission output section to move through its internal transmission structure. The first transmission output section then synchronously transmits the power to the second power input sections of the two second transmission components 5, and finally drives the corresponding push component 2 to reciprocate along the first preset direction through their respective second transmission output sections. This "single-source drive, graded transmission, dual-path output" structure ensures that the two push components maintain a high degree of synchronization in speed, stroke, and timing during movement, effectively avoiding material roll 100 skew, jamming, or equipment wear caused by asynchrony. At the same time, the power is distributed to the two push components 2 through a multi-stage transmission system, avoiding the situation where a single drive element directly bears double the load, reducing the load on the drive component 3, lowering the risk of overload, and helping to extend the service life of the drive component 3 and transmission components.

[0044] Furthermore, such as Figure 2 As shown, the first transmission component 4 includes: a first main sprocket 41, which is connected to the drive end of the drive component 3 to drive the first main sprocket 41 to rotate via the drive component 3; a first driven sprocket 42 and a first transmission chain, wherein the first driven sprocket 42 is rotatably disposed, and the first transmission chain is sleeved on the first main sprocket 41 and the first driven sprocket 42, and the first main sprocket 41 drives the first driven sprocket 42 to rotate via the first transmission chain; a transmission shaft 44, which extends along a second preset direction and is rotatably disposed, wherein the first driven sprocket 42 is sleeved on the transmission shaft 44, and the first driven sprocket 42 is relatively fixedly connected to the transmission shaft 44 to drive the transmission shaft 44 to rotate via the first driven sprocket 42; wherein the first preset direction is perpendicular to the second preset direction; the first main sprocket 41 forms a first power input part, and the transmission shaft 44 forms a first transmission output part.

[0045] With the above-described structure, the power from the drive component 3 drives the first main sprocket 41 to rotate via the drive end, which is then transmitted to the first driven sprocket 42 via the first transmission chain, thereby driving the transmission shaft 44, which is fixedly connected to it, to rotate. This chain drive structure features high transmission efficiency, strong load-bearing capacity, and stable operation, reliably transmitting driving force from the drive source to the subsequent transmission system. Simultaneously, by extending the transmission shaft 44 along a second preset direction perpendicular to the first preset direction, an orthogonal conversion of the power transmission direction is achieved, facilitating the rational layout of the drive and push components within a compact space and optimizing the overall machine structure. Meanwhile, the transmission shaft 44, as the first transmission output of the first transmission component, is arranged transversely (in the second preset direction), extending to both sides and connecting two second transmission components 5. Because the transmission shaft 44 rotates rigidly as a whole, the rotational speed and phase of the output ends on both sides are completely consistent, providing a reliable mechanical basis for the precise synchronous movement of the two subsequent push components 2, fundamentally avoiding thrust imbalance or equipment jamming caused by asynchronous transmission.

[0046] Among them, such as Figure 1 As shown, arrow C indicates the second preset direction, which is consistent with the axial direction of the large roll of material. This can be understood as the transverse direction of the support frame 1 or the transverse direction of the guide channel 10. The support guide rails 11 are spaced apart along the transverse direction of the support frame 1.

[0047] Furthermore, the first transmission component 4 and the drive component 3 are located at the bottom of the support frame 1.

[0048] Furthermore, the drive component 3 has a drive motor and a reducer. The output end of the drive motor is connected to the reducer. A first main sprocket 41 is sleeved on the output shaft of the reducer so that the first main sprocket 41 can be rotated by rotating the output shaft of the reducer.

[0049] Optionally, during actual operation, the moving speed of the large roll of material can be adjusted by controlling the rotation speed of the drive motor.

[0050] Furthermore, such as Figure 2 As shown, the storage rack also includes: a first support base 6 and a second support base 7, the first support base 6 and the second support base 7 are disposed on the installation reference, and the first support base 6 and the second support base 7 are spaced apart along a second preset direction; the drive shaft 44 is located between the first support base 6 and the second support base 7, and the two ends of the drive shaft 44 are rotatably disposed on the first support base 6 and the second support base 7 respectively.

[0051] With the above-described structural configuration, the two ends of the drive shaft 44 are rotatably mounted on the first support 6 and the second support 7, which are spaced apart along the second preset direction, forming a typical "simply supported at both ends" structure. This design effectively limits the radial runout and axial movement of the drive shaft 44 during rotation, significantly improving its rotational smoothness and motion accuracy, ensuring that power can be transmitted evenly and reliably to the second transmission components 5 on both sides, and avoiding uneven transmission or increased wear caused by shaft deformation or vibration.

[0052] Furthermore, the storage rack also includes a first bearing and a second bearing. The first bearing is installed in the first support seat 6, and the second bearing is installed in the second support seat 7. The two ends of the drive shaft 44 are rotatably supported on the first bearing and the second bearing, respectively.

[0053] Furthermore, the first support base 6 includes: a first bearing housing 61 and a first bearing housing fixing plate 62, the first bearing is installed in the first bearing housing 61, and the first bearing housing 61 is installed on the mounting reference through the first bearing housing fixing plate 62; the second support base 7 includes: a second bearing housing 71 and a second bearing housing fixing plate 72, the second bearing is installed in the second bearing housing 71, and the second bearing housing 71 is installed on the mounting reference through the second bearing housing fixing plate 72.

[0054] Specifically, such as Figure 2 and Figure 6 As shown, the second transmission component 5 includes: a second main sprocket 51, which is connected to the first transmission output unit to drive the second main sprocket 51 to rotate via the first transmission output unit; the second main sprocket 51 forms a second power input unit; two second driven sprockets 52, which are rotatably mounted on the support frame 1, spaced apart along a first preset direction, and whose axes are located in the same horizontal plane; a second transmission chain, which is sleeved on the second main sprocket 51 and the two second driven sprockets 52; a pushing component 2 is mounted on the bearing section of the second transmission chain, and the second main sprocket 51 drives the pushing component 2 to reciprocate along the first preset direction via the second transmission chain; the second transmission chain forms a second transmission output unit.

[0055] With the above-described structure, the second main sprocket 51 serves as the second power input unit, connected to the first transmission output unit of the first transmission component 4, receiving power from the drive source. Power is transmitted via the second transmission chain to two spaced-apart second driven sprockets 52, forming a stable circular transmission path. This chain drive structure has the advantages of high load-bearing capacity, smooth transmission, and low slippage, reliably converting rotational motion into reciprocating linear motion of the pushing component 2. Furthermore, the two second driven sprockets 52 are rotatably mounted on the support frame 1, and their axes are located in the same horizontal plane, ensuring that the running plane of the second transmission chain is straight and the force is uniform. The pushing component 2 is located on the load-bearing section of the second transmission chain, so that during the pushing process, this section of the chain is in a tensioned state, directly transmitting the thrust. This design effectively avoids instability caused by chain sagging, shaking, or deviation, ensuring that the pushing component 2 moves smoothly and accurately along the first preset direction, significantly improving the pushing accuracy and positioning reliability of the large material roll. Furthermore, by arranging two second driven sprockets 52 at intervals along the first preset direction, a longer transmission span can be achieved, meeting the needs of large-size storage racks or continuous pushing across multiple workstations. This flexible structural layout allows for adjustment of the sprocket spacing according to actual needs, adapting to material conveying paths of different lengths and enhancing the equipment's versatility and adaptability.

[0056] The aforementioned "bearing section of the second transmission chain" can be understood as the effective working section of the second transmission chain on the force-bearing side, which is fitted between the two second driven sprockets 52. Specifically, this bearing section refers to the key part of the transmission chain that is in a tensioned state during closed-loop operation, directly bearing the driving force and realizing power transmission. In the current structural layout, this section of the chain connects two spaced-apart second driven sprockets 52, is located in the top area between the two sprockets, and runs horizontally.

[0057] Furthermore, the second main sprockets 51 of the two second transmission components 5 are both sleeved on the transmission shaft 44, and the two second main sprockets 51 are spaced apart along the axial direction of the transmission shaft 44. One of the two second main sprockets 51 is located at the end of the transmission shaft 44 where the first main sprocket 41 is located, and the second main sprocket 51 is spaced apart from the first main sprocket 41.

[0058] Furthermore, such as Figure 6As shown, the second transmission component 5 further includes at least one drop wheel 54, which is rotatably mounted on the support frame 1. The drop wheel 54 is located on the side of the support frame 1 near one of the two second driven sprockets 52. The drop wheel 54 is spaced apart from the second driven sprocket 52 and is located below the second driven sprocket 52. The drop wheel 54 presses against the second transmission chain, thereby applying a preload to the second transmission chain. Through this structure, the drop wheel 54 can effectively tension the second transmission chain, keeping it in a moderate tension state, preventing sagging, skipping teeth, slippage, abnormal noise, or transmission failure caused by chain slack, ensuring smooth and reliable power transmission, improving chain meshing quality, reducing operating vibration, and extending the service life of the transmission system.

[0059] Optionally, there are two droppers 54, which are spaced apart along a first preset direction. The two droppers 54 are arranged in a one-to-one correspondence with the two second driven sprockets 52, and the two droppers 54 are located between the two second driven sprockets 52.

[0060] Furthermore, such as Figure 6 As shown, the storage rack also includes a first mounting plate 200, which is movably mounted on the support frame 1 along the height of the support frame 1, and is located on one side of the support frame 1. A dropper wheel 54 is rotatably mounted on the first mounting plate 200, so that by adjusting the position of the first mounting plate 200 on the support frame 1, the dropper wheel 54 can be moved synchronously, thereby precisely adjusting the preload applied by the dropper wheel to the second transmission chain.

[0061] Optionally, two first mounting plates 200 are provided on opposite sides of the support frame 1, and the two first mounting plates 200 on each side are respectively arranged in a one-to-one correspondence with the two drop wheels 54 of the corresponding second transmission component 5.

[0062] In this context, the opposite sides of the support frame 1 refer to the two opposite sides of the support frame 1 along its lateral direction. The opposite sides of the guide channel 10 refer to the two opposite sides of the guide channel 10 along its lateral direction.

[0063] Specifically, such as Figure 4 and Figure 6 As shown, the storage rack also includes two chain guide bars 8, both of which extend along a first preset direction. The two chain guide bars 8 are mounted on the support frame 1 and are located on opposite sides of the guide channel 10. The two chain guide bars 8 are correspondingly arranged with the two second transmission components 5. The chain guide bars 8 are located between the corresponding two second driven sprockets 52 and below the bearing section of the corresponding second transmission chain. The chain guide bars 8 are used to support and guide the bearing section of the second transmission chain.

[0064] With the above-described structure, the chain guide bar 8 extends along a first preset direction, positioned below the load-bearing section of the corresponding second transmission chain, and located between the two second driven sprockets 52. It directly provides continuous support to the load-bearing section under tension, effectively resisting sagging caused by the chain's own weight and the load of the pushing component 2, ensuring the chain remains straight and stable during pushing, and avoiding operational vibration or interference with the frame due to excessive sagging. Simultaneously, by setting the chain guide bar 8, the chain load can be distributed and local stress concentration reduced, thereby effectively reducing wear at the chain-sprocket meshing points. Furthermore, stable support and guidance reduce abnormal friction and impact, delaying chain tension and fatigue failure, and extending the maintenance cycle and service life of the entire transmission system.

[0065] Optionally, the chain guide bar 8 is a convex wear-resistant bar.

[0066] Specifically, such as Figure 6 As shown, the storage rack also includes: two sets of tensioning components, each set of tensioning components being arranged in a one-to-one correspondence with two second transmission components 5; each set of tensioning components having at least one tensioning assembly 9; the tensioning assembly 9 having a movable part, the movable part being movably disposed on the support frame 1 along a first preset direction relative to the support frame 1; one of the two second driven sprockets 52 being rotatably disposed on the movable part, so as to drive the corresponding second driven sprocket 52 to move along the first preset direction by moving the movable part, so as to adjust the tension of the second transmission chain.

[0067] With the above-described structure, the tensioning assembly 9 has a movable part that can move relative to the support frame along a first preset direction, and a second driven sprocket 52 is rotatably mounted on the movable part. By driving the movable part to move back and forth, the second driven sprocket 52 can be moved synchronously, thereby achieving precise, reliable, and adjustable control of the tension of the second transmission chain. This not only improves the stability and accuracy of the transmission system but also enhances the maintainability and durability of the equipment.

[0068] Furthermore, each tensioning component has two tensioning assemblies 9, and the two tensioning assemblies 9 are arranged in a one-to-one correspondence with the two second driven sprockets 52 of the corresponding second transmission component 5.

[0069] Furthermore, such as Figure 6As shown, the tensioning assembly 9 includes a second mounting plate 91, a fixing seat 92, and a screw 93. The second mounting plate 91 is movably mounted on the support frame 1 along a first preset direction, forming a moving part of the tensioning assembly 9. The fixing seat 92 is fixedly mounted on the support frame 1, and is spaced apart from the second mounting plate 91 along the first preset direction, with the fixing seat 92 located on the side of the second mounting plate 91 away from the chain guide bar 8. The fixing seat 92 has an internal threaded hole that extends along the first preset direction. The screw 93 has an external thread that matches the internal threaded hole, forming a threaded engagement with the internal thread. One end of the screw 93 passes through the fixing seat 92 and is fixedly connected to the second mounting plate 91, thereby rotating the screw 93 to drive the second mounting plate 91 to reciprocate along the first preset direction.

[0070] Furthermore, the tensioning assembly 9 also includes a locking element, which is used to lock the screw 93 after the tension adjustment is completed to prevent it from loosening due to vibration or load changes, and to ensure that the tension state is stable and reliable in the long term.

[0071] Optionally, the locking element is at least one locking nut, which is sleeved on the screw 93 and located on the side of the fixed seat 92 near the second mounting plate 91. After the chain tension adjustment is completed, the locking nut is rotated to make it abut against the end face of the fixed seat 92, generating frictional resistance to prevent the screw 93 from loosening due to equipment vibration or load changes, thereby reliably locking the position of the second mounting plate 91 and maintaining the preset tension state of the second transmission chain.

[0072] Optionally, the working process of the two pushing components 2 is as follows: Initial state: The push arms 22 of the two push components 2 are located on the side of the target material roll away from the target position, and each push arm 22 is in a preset push posture, ready to perform the push action.

[0073] Promotion phase: When it is necessary to push the large roll of the target material, the drive motor of the drive component 3 rotates in the first preset direction, driving the first main sprocket 41 to rotate. The first main sprocket 41 drives the first driven sprocket 42 to rotate through the first transmission chain, thereby driving the transmission shaft 44 to rotate, so that the transmission shaft 44 drives the second main sprockets 51 of the two second transmission components 5 to rotate synchronously.

[0074] The second main sprocket 51 rotates, driving the second transmission chain to run and driving the two second driven sprockets 52 to rotate. Thus, through the movement of the second transmission chain, the moving plate 21 of the corresponding pushing component 2 moves towards the target position along the first preset direction.

[0075] As the two moving plates 21 move synchronously, the two pushing arms 22 come into contact with the two ends of the target material roll, and as the two moving plates 21 continue to move, the two pushing arms 22 apply a pushing force to the two ends of the target material roll, causing it to move towards the target position.

[0076] Reset return phase: Once the target material roll has moved to the target position, the push arm 22 of each push component 2 is located on the side of the next material roll to be pushed that is close to the target position. At this time, in preparation for the next pushing cycle, the drive motor switches direction and rotates in the opposite direction.

[0077] Through the linkage of the first transmission component 4 and the two second transmission components 5, the transmission system runs in reverse, driving the two pushing components 2 to move in a direction away from the target position.

[0078] During the return journey, the moving plate 21 drives the push arm 22 past the next large roll of material to be pushed. When the push arm 22 contacts the side of the large roll of material closest to the target position, under the obstruction of the large roll of material, the push arm 22 receives a reaction force and automatically swings around the connecting shaft 25 in a direction away from the large roll of material, entering an avoidance posture. In this posture, the push arm 22 smoothly passes the large roll of material from below or close to the side, achieving non-interference obstacle crossing and avoiding collisions or jamming.

[0079] Attitude reset and cycle preparation: As the moving plate 21 continues to drive the corresponding pushing arm 22 to move to the side of the next roll of material to be pushed away from the target position, and after the pushing arm 22 disengages from the next roll of material to be pushed, the pushing arm 22 returns from the avoidance posture to the pushing posture under the action of the elastic reset member 26. Thus, the two pushing components 2 return to the initial working state, and are capable of pushing the next roll of material, thereby realizing a continuous, automatic, and reciprocating material pushing cycle.
