Description

Technical Field

[0001] This invention relates to a bidirectional conveyor belt conveyor in the field of material conveying, belonging to the field of material conveying technology. Background Technology

[0002] Existing material conveying equipment suffers from a core drawback: poor adaptability for bidirectional switching in directional and position adjustment. This makes it difficult to meet the flexible conveying needs of diverse scenarios. Most conveyors only have a preset transmission path in a single conveying direction, with the lateral and longitudinal conveying mechanisms operating independently and lacking a coordinated connection structure. This fails to form a cross-linked power transmission system. Furthermore, support and positioning components are mostly of fixed specifications, making it impossible to adjust height and limit parameters in real time according to directional switching requirements. Conventional solutions include adding extra conveying branches to transfer materials, using multiple devices to achieve directional switching, or manually adjusting the support structure to adapt to different conveying directions. However, these methods have significant drawbacks: multiple devices increase system complexity and floor space; material accumulation and jamming are prone to occur at the connection points between devices, reducing conveying efficiency; and insufficient adjustment precision can easily lead to material slippage and deviation, making it difficult to guarantee conveying stability. These drawbacks are further amplified in scenarios involving continuous batch material conveying, affecting the continuity and reliability of the overall production process. Therefore, there is an urgent need for bidirectional conveyor belt conveyors in the field of material conveying to solve these problems. Summary of the Invention

The bottom of the connecting seat 33 has a set of electric cylinders 34 for height adjustment.

[0025] The limiting support roller 31 includes an outer rubber layer 1a, a liquid nano protective layer 1b, an inner rubber layer 1c, an inner support insert 1d, a flexible patch 1e, an inner liner shell 1f, an inner support insert 2g, an inner support tooth core 1h, a groove 1i, a bearing seat 1j, an inner sealing sleeve 1k, a micro compression airbag 1l, and a force-expanding bearing seat 1m. The inner side of the outer rubber layer 1a is provided with a set of liquid nano protective layers 1b for providing flexible support to the outer rubber layer 1a. The inner side of the liquid nano protective layer 1b is provided with a set of inner rubber layers 1c. The inner side of the inner rubber layer 1c is provided with several sets of inner support inserts 1d for supporting the inner liner shell 1f. The several sets of inner support inserts 1d are distributed in a ring structure. The inner side of the inner support insert 1d and the inner liner shell 1f are provided with a set of flexible patches 1e for maintaining the impact pressure when the material position is blocked. The flexible patch 1e is sealed and fitted at the connection with the inner support insert 1d and the inner liner shell 1f. The inner liner shell 1f is provided with two sets of micro compression airbags 1l for buffering the pressure of the outer rubber layer 1a and the liquid nano protective layer 1b. The micro compression airbags 1l are provided with a set of force-expanding bearings 1m on the upper and lower sides to expand their support area. The bottom of the two sets of force-expanding bearings 1m at the lower end is provided with a set of inner sealing sleeves 1k for buffering support. The lower end of the inner sealing sleeves 1k is provided with a set of bearing seats 1j for support. The bottom of the bearing seats 1j is provided with a set of inner support inserts 1g for supporting the inner support tooth core 1h. The inner side of the inner rubber layer 1c is provided with several sets of fixed installation grooves for positioning and installation with the inner support insert 1d. The outer side of the inner support tooth core 1h has several sets of fixed mounting grooves for positioning and installation with the inner support insert 1g. Inside the fixed mounting grooves is a set of inner support tooth cores 1h for maintaining the stable rotation of the limiting support roller 31. Inside the inner support tooth core 1h is a set of mandrels for penetration into the side limiting seat 32. The mandrels penetrate the inner support tooth core 1h and mesh with several sets of meshing grooves 1i inside. Each set includes an inner support insert 1d, a flexible layer 1e, and an inner liner shell. 1f, the inner support insert 1g, and the corresponding load-bearing seat 1j, inner sealing sleeve 1k, micro-compression airbag 1l, and force-expanding support 1m installed inside the inner liner shell 1f constitute a material retention and buffer structure. Several sets of the material retention and buffer structure are arranged in a ring structure. The limiting support roller 31 is constructed in a multi-layered structure in conjunction with the buffer assembly. The outer rubber layer 1a directly contacts the material to form initial protection, while the inner liquid nano-protective layer 1b provides flexible support, working in conjunction with the inner rubber layer 1c. To enhance the overall structural flexibility, the inner support insert 1d is arranged in a ring and sealed to the inner liner shell 1f through a flexible adhesive layer 1e. This ensures support stability and buffers the impact pressure when materials are blocked. The miniature compressed air bladder 1l inside the inner liner shell 1f, combined with the force-expanding bearing 1m, can efficiently absorb the pressure transmitted by the outer rubber layer 1a. The inner sealing sleeve 1k and the bearing seat 1j further enhance the buffering support effect. The inner support insert 1g achieves a stable connection with the inner support tooth core 1h. The inner support tooth core 1h cooperates with the side limiting seat 32 through the mandrel, and the meshing groove ensures the stability of the rotational connection. Multiple sets of ring-shaped material retention and buffering structures form all-round protection. In actual use, this structure solves the problems of insufficient buffering and easy wear of existing limiting components. When facing material impact, it can unload force in multiple layers to avoid material deviation or damage, while ensuring stable rotation without hindering the conveying process. This improves the safety and regularity of the bidirectional conveying process, adapts to diverse conveying scenarios of medium and large materials, and enhances the overall durability and adaptability of the equipment.
