Description

Technical Field

[0001] This utility model relates to the field of workshop conveying devices, and in particular to a flexible soft-connection transmission device. Background Technology

[0002] In modern workshop production operations, material conveying is a core link connecting various production stations and ensuring the orderly operation of the assembly line. Currently, the material conveying mechanisms used in workshops are mostly fixed conveying equipment. The overall installation position, conveying length, and structural form of this type of equipment are all fixed, and it can only adapt to the preset conveying routes and fixed working conditions planned in the early stage of production. Its structural adjustability and on-site adaptability are extremely poor.

[0003] With the increasing variety of products produced in the workshop and the flexible adjustment of production processes, temporary workstation docking, temporary material transfer, and adaptive conveying of materials at different distances frequently arise on the production site. However, traditional fixed conveying equipment cannot flexibly adjust the conveying length and position according to temporary work scenarios, making it difficult to quickly adapt to newly added temporary conveying lines. When temporary conveying needs arise on site, workers need to modify the existing fixed conveying structure or set up a completely new conveying mechanism. The overall construction process is cumbersome and complex, involving multiple tasks such as frame construction, transmission component layout, and position calibration. This not only consumes a lot of manpower and time costs, but also has a long construction cycle, low work efficiency, and is extremely difficult to set up on site, which can easily affect the overall production progress of the workshop.

[0004] Meanwhile, fixed conveyor equipment has a fixed structure and cannot be retracted for storage. After temporary operations are completed, the equipment occupies valuable workshop space for an extended period, leading to reduced workshop space utilization. Furthermore, the overall transportation and storage of the equipment is extremely inconvenient, making it unsuitable for the flexible production needs of workshops in various scenarios and with changing demands. In summary, existing fixed conveyor equipment suffers from technical defects such as poor adaptability to operating conditions, low efficiency in temporary deployment, low space utilization, and insufficient versatility, making it difficult to meet the flexible, efficient, and emergency temporary material conveying needs of modern workshops.

[0042] Example 1

[0043] Please see Figures 1-4 This utility model provides a flexible soft connection transmission device, including a support part, a conveying part, a connecting part, and a driving part;

[0044] The support section includes a plurality of support frames 100 and movable frames 200 arranged at intervals, and an adjusting wheel 120 disposed at the bottom of the support frame 100; the conveying section includes a plurality of conveying rollers 310; the connecting section includes a first connecting section 410 and a second connecting section 420 respectively disposed on both sides of the support section; the driving section includes a plurality of intermediate wheels 520, and a drive motor 510 for driving the intermediate wheels 520.

[0045] The first connecting part 410 and the second connecting part 420 both include several sets of staggered rotating connecting plates 421. Each set of connecting plates 421 is rotatably connected by a rotating member. The several sets of staggered rotating connections can be expanded or contracted based on their connection positions.

[0046] The intermediate wheel 520 is connected to two adjacent conveyor rollers 310 via a synchronous belt 530; the intermediate wheel 520 is rotatably connected to the rotating component; both ends of the intermediate wheel 520 are connected to the movable frame 200 via a pair of hanging plates 210, and the hanging plates 210 are rotatably connected to the intermediate wheel 520 and the movable frame 200 respectively.

[0047] The drive motor 510 is connected to one of the intermediate wheels 520. Both ends of the drive motor 510 are connected to the movable frame 200 through a pair of hanging plates 210. The hanging plates 210 are rotatably connected to the drive motor 510 and the movable frame 200 respectively.

[0048] Specifically, the device mainly consists of a support section, a conveying section, a connecting section, and a driving section. These parts work together to form an integrated equipment structure that can flexibly extend and retract and stably convey materials.

[0049] The support unit, serving as the load-bearing foundation of the entire device, is equipped with several support frames 100 and movable frames 200. All support frames 100 and movable frames 200 are evenly spaced along the conveying direction to ensure uniform stress distribution and stable support of the overall structure. Each support frame 100 is equipped with adjusting wheels 120 at its bottom. These wheels allow for the overall movement and leveling of the device, facilitating rapid relocation and deployment to meet temporary conveying needs in the workshop and adapting to the installation and usage requirements of different work sites.

[0050] The conveying section is the core structure for material conveying, consisting of several conveying rollers 310. These rollers are arranged sequentially along the conveying direction, forming a continuous material conveying support surface to directly support and drive the material forward. Connecting sections are symmetrically arranged on the left and right sides of the support section, specifically divided into a first connecting section 410 and a second connecting section 420. These connecting sections work together to achieve the flexible telescopic function of the entire device. Both the first connecting section 410 and the second connecting section 420 are composed of multiple sets of connecting plates 421. Each set of connecting plates 421 uses an interleaved rotating connection assembly method. Adjacent connecting plates 421 are connected and engaged through rotating parts, allowing the overall connecting structure composed of multiple sets of connecting plates 421 to flexibly expand or contract based on the force applied and the connection position. This enables adjustment of the overall length of the entire conveying device, adapting to temporary conveying conditions of different distances.

[0051] The drive unit provides power for the conveying process and mainly includes several intermediate wheels 520 and a drive motor 510. The drive motor 510 serves as the power source to drive the intermediate wheels 520 to operate stably. Each intermediate wheel 520 is connected to two adjacent conveyor rollers 310 via a synchronous belt 530, achieving synchronous power transmission and ensuring the synchronous rotation of multiple conveyor rollers 310, thus guaranteeing the continuity and stability of material conveying. The intermediate wheels 520 are rotatedly engaged with the rotating parts of the connecting plate 421. Both ends of the intermediate wheels 520 are assembled to the movable frame 200 via a pair of hanging plates 210. The two ends of the hanging plates 210 are rotatably connected to the intermediate wheels 520 and the movable frame 200, respectively, achieving both positioning and installation of the intermediate wheels 520 without affecting their normal rotation operation.

[0052] The drive motor 510 is also assembled and fixed via the mounting plate 210. A pair of mounting plates 210 are matched to each end of the drive motor 510, forming a rotatable connection structure with the movable frame 200 through the mounting plates 210. This ensures the drive motor 510 is securely installed while allowing for minor deformation adjustments to the overall structure. In this embodiment, through the above structural cooperation, the hinged connecting plate 421 structure enables the flexible extension and retraction of the entire device, eliminating the need for complex on-site setup and modification. It can quickly adapt to temporary conveying needs in the workshop. Simultaneously, the transmission cooperation between the intermediate wheel 520 and the synchronous belt 530 ensures that the equipment can still stably complete material conveying operations in the extended state.

[0053] Furthermore, the support frame 100 includes a first support rod 111 and a second support rod 112, and a connecting rod 113 connecting the first support rod 111 and the second support rod 112; the adjusting wheel 120 is disposed at the bottom of the first support rod 111 and the second support rod 112; the conveying part and the movable frame 200 are both disposed between the first support rod 111 and the second support rod 112.

[0054] Specifically, each support frame 100 consists of a first support rod 111, a second support rod 112, and a connecting rod 113. The first support rod 111 and the second support rod 112 are parallel to each other and vertically aligned, and are fixedly connected by the horizontally arranged connecting rod 113. This allows the three components to work together to form a stable, integrated frame structure, effectively improving the overall structural strength and load-bearing stability of the support frame 100 and preventing deformation. The adjusting wheels 120 are correspondingly mounted at the bottom of the first support rod 111 and the second support rod 112. The symmetrically arranged adjusting wheels 120 on both sides jointly support the overall frame, allowing for free movement of the entire device to meet the needs of rapid switching of temporary conveying points in the workshop. The adjusting wheels 120 also allow for leveling of the equipment, ensuring the stability of the conveying operation. Meanwhile, each conveying roller 310 of the conveying section and each movable frame 200 of the support section are respectively assembled in the area between the first support rod 111 and the second support rod 112, forming a stable installation position by relying on the support rods on both sides. The structure is compact and reasonable, which can make full use of the internal space of the support frame 100, ensure the precise matching between the conveying structure and the support structure, and provide a structural foundation for subsequent flexible extension and stable conveying.

[0055] Furthermore, the movable frame 200 includes a plurality of movable rollers 220, and the movable rollers 220 at both ends of the movable frame 200 are fixed on the support frame 100; the two ends of the connecting plate 421 are rotatably connected to the movable rollers 220 and the conveying rollers 310, respectively.

[0056] Furthermore, the connecting plate 421 is provided with a first connecting hole 422, a second connecting hole 423, and a third connecting hole 424 at both ends and the middle position, respectively; the connecting plates 421 are rotatably connected to each other at the third connecting hole 424 by a rotating member; the connecting plate 421 is rotatably connected to one end of the conveying roller 310 at the first connecting hole 422 by a rotating member; the connecting plate 421 is rotatably connected to one end of the movable roller 220 at the second connecting hole 423 by a rotating member.

[0057] Furthermore, the movable rollers 220, serving as rotating components of the movable frame 200, are evenly distributed across the overall structure of the movable frame 200. Specifically, the movable rollers 220 at both ends of the movable frame 200 are fixedly mounted on the support frame 100, while the movable rollers 220 in the middle are connected to the intermediate wheels 520 via hanging plates 210. This ensures that the movable frame 200 as a whole relies on the support frame 100 to form a stable installation reference, guaranteeing a relatively fixed overall position and providing robust support for the subsequent telescopic hinge structure. The connecting plate 421, as the core component for realizing the flexible telescopic movement of the device, has its two ends respectively forming a rotating connection with the movable rollers 220 and the conveyor rollers 310, allowing the connecting plate 421 to rotate freely relative to the movable rollers 220 and the conveyor rollers 310, providing rotational freedom for the extension and retraction of the overall structure.

[0058] Specifically, each connecting plate 421 has a first connecting hole 422, a second connecting hole 423, and a third connecting hole 424 at both ends and the middle position along its own length. The three connecting holes correspond to different connection points, realizing precise multi-position connection assembly. Adjacent connecting plates 421 are rotatably connected through the third connecting hole 424 with a rotating component, forming an interlocking connection structure among multiple sets of connecting plates 421. All connecting plates 421 can be folded and unfolded as a whole, relying on the connection fulcrum of the third connecting hole 424. Simultaneously, the connecting plate 421 is rotatably connected to one end of the corresponding conveyor roller 310 through the first connecting hole 422 at its end with a rotating component, and rotatably connected to one end of the corresponding movable roller 220 through the second connecting hole 423 with a rotating component. Through the above-mentioned three-hole staggered connection structure, each connecting plate 421 can simultaneously link the movable roller 220 and the conveying roller 310. When the overall structure is subjected to force to adjust the length, each group of connecting plates 421 rotates synchronously around each connection point, orderly completing the extension and contraction of the overall device. Moreover, the connection and cooperation are highly accurate and the rotation is smooth throughout the process, without jamming or deviation, effectively ensuring the stability and reliability of the device's extension and contraction adjustment. At the same time, it ensures that the relative position of the conveying roller 310 and the movable roller 220 is adaptively adjusted with the extension and contraction action, meeting the changing temporary conveying operation requirements.

[0059] Furthermore, the intermediate wheel 520 includes a first transmission position 521 and a second transmission position 522 arranged at intervals; a plurality of conveying rollers 310 are provided with a first type of connection position 311 or a second type of connection position 312 adapted to the first transmission position 521 or the second transmission position 522; the first transmission position 521 and the second transmission position 522 are respectively connected to the first type of connection position 311 and the second type of connection position 312 of the adjacent conveying rollers 310 through the synchronous belt 530.

[0060] Furthermore, in this embodiment, the intermediate wheel 520 is provided with a first transmission position 521 and a second transmission position 522 spaced apart along its wheel body axial direction. The two transmission positions are independent of each other and arranged in separate zones, and can respectively connect to different conveyor rollers 310 to achieve independent zoned transmission. Correspondingly, each conveyor roller 310 has a first type of connection position 311 adapted to the first transmission position 521 and a second type of connection position 312 adapted to the second transmission position 522, respectively, to achieve precise matching and docking of the transmission structure. During assembly, the first transmission position 521 of the intermediate wheel 520 is connected to the first type of connection position 311 of the adjacent conveyor roller 310 through a synchronous belt 530, and the second transmission position 522 of the intermediate wheel 520 is connected to the second type of connection position 312 of the adjacent conveyor roller 310 through another set of synchronous belts 530. This dual-point partitioned transmission structure allows a single intermediate wheel 520 to simultaneously and independently power two adjacent conveyor rollers 310 on both sides, resulting in uniform transmission ratios and high consistency in power transmission. Even when the device is in an extended or retracted adjustment state, the adaptation relationship between each transmission position and its corresponding connection position remains unchanged. The transmission mating distance of the synchronous belt 530 can adaptively adapt to the structural fine-tuning, effectively avoiding problems such as transmission derailment, power interruption, and asynchronous conveying during the extension and retraction process, greatly improving the transmission stability and conveying reliability of the device under flexible extension and retraction conditions.

[0061] Furthermore, the hanging plate 210 is provided with a rotating groove 211 that is rotatably connected to the movable roller 220.

[0062] Furthermore, the two ends of the drive motor 510 are respectively provided with mounting brackets 230 via a pair of hanging plates 210, and the hanging plates 210 at both ends of the drive motor 510 are rotatably connected to the two ends of the mounting brackets 230 respectively; the drive motor 510 is mounted on the mounting brackets 230.

[0063] Furthermore, several rotatable limiting wheels 430 are provided at intervals on several connecting plates 421, and several limiting wheels 430 on the first connecting part 410 and the second connecting part 420 form a conveying channel.

[0064] Specifically, the drive motor 510 is also assembled and fixed by the mounting plate 210. Each end of the drive motor 510 is matched with a pair of mounting plates 210, and the mounting plates 210 form a rotating connection structure with the movable frame 200. This ensures that the drive motor 510 is installed stably, and the deformation adjustment of the overall structure can be adapted by the mounting plates 210.

[0065] Furthermore, in this embodiment, each set of connecting plates 421 is uniformly spaced with freely rotatable limiting wheels 430. The limiting wheels 430 are integrally arranged with the connecting plates 421 and can rotate independently without interfering with the hinge rotation of the connecting plates 421. The first connecting part 410 and the second connecting part 420 are respectively arranged on the left and right sides of the conveying direction of the device. The limiting wheels 430 on all connecting plates 421 on both sides correspond to each other and are symmetrically arranged, forming a material conveying channel that runs through the entire device. During the extension or retraction adjustment of the device, the limiting wheels 430 synchronously rotate and change their spacing with the connecting plates 421. The relative spacing between the limiting wheels 430 on both sides always remains matched, allowing the conveying channel formed to adapt to the overall length of the device by synchronously extending and retracting. When the material is conveyed forward on the conveying rollers 310, the rotatable limiting wheels 430 on both sides can laterally limit and guide the material, preventing deviation, misalignment, or falling during flexible conveying and equipment extension / retraction adjustments. Meanwhile, the limit wheel 430 adopts a rotatable structure, which can form rolling contact with the side wall of the material, greatly reducing the lateral frictional resistance of the material, ensuring smooth and stable material conveying, and further improving the conveying accuracy and operational stability of the overall device under flexible telescopic conveying conditions.

[0066] This embodiment achieves flexible extension and retraction of the entire device through the above-mentioned structural cooperation and the rotating connecting plate 421 structure. It does not require complicated on-site construction and modification and can quickly adapt to temporary conveying needs in the workshop. At the same time, the transmission cooperation between the intermediate wheel 520 and the synchronous belt 530 ensures that the equipment can still stably complete material conveying operations in the extension and retraction state.

[0067] The overall telescopic adjustment of this device relies on the symmetrically arranged rotating connecting plates 421 on both sides, which is the core principle of the flexible adjustable length of the equipment. The first connecting part 410 and the second connecting part 420 on the left and right sides of the device are composed of multiple sets of connecting plates 421 that are staggered and rotated. Each connecting plate 421 forms a rotation fulcrum based on the third connecting hole 424 in the middle position. At the same time, it connects the conveying roller 310 and the movable roller 220 through the first connecting hole 422 and the second connecting hole 423 at both ends, respectively, forming a multi-point linkage flexible rotating connection system. When it is necessary to adjust the extension or contraction to adapt to different conveying distances, each set of connecting plates 421 rotates synchronously around the central rotating connecting point. The staggered folding connecting plates 421 expand outward or retract inward, driving the distance between the adjacent support frame 100 and the movable frame 200 to change synchronously, thereby realizing the stepless adjustment of the overall length of the entire conveying device. The rotation of each hinge point is smooth and synchronous throughout the process, and the structure is free from jamming. The length and shape of the equipment can be flexibly adjusted according to the temporary conveying needs of the workshop to adapt to various working conditions.

[0068] This device relies on a zoned synchronous belt 530 transmission structure to achieve stable material conveying throughout the entire process, ensuring uninterrupted conveying function during telescoping. The device uses a drive motor 510 as its core power source, driving intermediate pulleys 520 to rotate continuously. Each intermediate pulley 520 is axially spaced at a first transmission position 521 and a second transmission position 522, which can respectively connect to the first type of connection position 311 and the second type of connection position 312 of the conveyor rollers 310 on both sides via the synchronous belt 530, forming a single-wheel, dual-drive synchronous transmission structure. Power is transmitted step-by-step to each conveyor roller 310 via the intermediate pulleys 520 and the synchronous belt 530, ensuring that all conveyor rollers 310 rotate synchronously and uniformly, forming continuous and stable material conveying support and power output on the roller surface. This transmission structure has self-adaptive characteristics; during the dynamic adjustment process of the device's extension and retraction, the matching relationship of the transmission points remains unchanged. The synchronous belt 530 can be finely adjusted and adaptively adapted according to the spacing of the frame, effectively avoiding problems such as power interruption, asynchronous conveying, and deviation, achieving synchronous dynamic adjustment and continuous conveying.

[0069] The device further enhances overall conveying stability and adaptability to various operating conditions through the coordinated use of a limiting and guiding structure with a flexible telescopic and transmission structure. Multiple sets of rotatable limiting wheels 430, symmetrically arranged on the connecting plates 421 on both sides, form a through-type material conveying channel. The limiting wheels 430 can adjust their position and spacing synchronously with the telescopic movement of the connecting plates 421, enabling the conveying channel to adaptively expand and contract with the overall equipment. During the material's movement on the conveying rollers 310, the limiting wheels 430 on both sides provide lateral limiting and rolling guidance, effectively avoiding problems such as material deviation, falling, and jamming that are prone to occur in flexible adjustable structures during dynamic operations, and reducing lateral frictional resistance of the material. The overall structure achieves integrated collaborative operation of telescopic adjustment, synchronous transmission, and limiting guidance, enabling rapid adaptation to temporary workstation docking and temporary line layout scenarios in workshops, balancing ease of deployment with conveying stability.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
