Description

Technical Field

[0001] This utility model relates to the technical field of top plate chain devices, and in particular to a double-row drive roller top plate chain. Background Technology

[0002] In the field of automated production and material handling, chain conveyor systems, as key equipment connecting various processes, directly impact production efficiency and product quality due to their operational stability and ability to protect conveyed products. Currently, conventional chain structures are mostly composed of rollers, chain plates, and other components. Gaps often exist between adjacent rollers or chain links, and existing top-plate chains lack mounting holes. When conveying smaller items, these items can easily fall into the gaps, leading to damage or loss. During transport, products are easily displaced by vibrations generated by the equipment, potentially falling into chain gaps and causing jamming, deformation, or even damage. Furthermore, due to the lack of effective lateral restraint and protective structures, products may fall from the side of the chain under vibration or high-speed transport conditions, resulting in product loss or scratches. This not only increases production costs but also severely impacts the continuity of the production process. Moreover, vibration problems in traditional chain conveyor systems are difficult to control effectively. When the equipment is running, the contact between the rollers and the track, and the relative movement between the chain links will generate continuous micro-vibrations. Although these micro-vibrations are small in amplitude, they can cause hidden damage such as loosening of internal structure and falling off of parts when they act on the conveyed products for a long time, especially for products that are fragile, delicate or have a precise structure, further reducing the product qualification rate.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4This utility model embodiment of a double-row transmission roller top plate chain includes: chain links 1, connecting chain links 2, connecting rods, and rollers 7, forming the basic structure of the top plate chain device. The surface of the connecting chain links 2 is provided with several adjustment holes 3 for adjusting the spacing between the rollers 7, facilitating better adaptation and support of different types of items by the top plates 5 and 8. The chain links 1 are fixedly connected to the connecting rods and to the rollers 7. At least four chain links 1 are arranged side-by-side, and the four chain links 1 are fixedly connected to each other by the connecting rods, forming a double-row, driveable top plate chain structure. The rollers 7 and... The connecting rod is rotatably connected, and the roller 7 is located between the two chain links 1. Its main function is to replace sliding friction with rolling friction, reduce resistance and wear during mechanical operation, and assist in transmitting power or enabling the top plate 1 5 and top plate 2 8 to support the load. The top plate 1 5 is fixedly connected to the upper surface of the chain link 1 for carrying goods. The upper surface of the top plate 1 5 has a mounting hole 1 51 for combining with the mounting hole 2 61 to fix the material box 6 to the top plate 1 5. The upper surface of the top plate 1 5 has a material box 6 for holding smaller items. The bottom surface of the material box 6 has a mounting hole 2 61.

[0023] Specifically, the number and position of mounting holes 51 and 61 are the same, which enhances the stability of the top plate 5 and the material box 6 after they are combined. The upper surface of the top plate 5 is provided with a connecting groove 52, and the bottom surface of the material box 6 is fixedly connected with a connecting ring 62, which is used to more accurately combine the top plate 5 and the material box 6, so that the mounting holes 51 and 61 are fixed together. The connecting groove 52 and the connecting ring 62 have the same shape. The connecting groove 52 and the connecting ring 62 are located in the inner ring position of the mounting holes 51 and 61 respectively, which is suitable for different models of material boxes 6, making it convenient to fix different models of material boxes 6 to the top plate 5, and can also be adapted to different models of items. A top plate 2 8 is fixedly connected to the upper surface of link 1. Top plate 2 8 is spaced apart from top plate 1 5 to facilitate the simultaneous transport of different items and to prevent smaller items from falling into the gap between top plate 1 5 and top plate 2 8. Several adjustment holes 3 are provided on the surface of the connecting link 2. The adjustment holes 3 have the same diameter as the connecting rod and are used to adjust the spacing between the rollers 7 so that the top plate 1 5 and top plate 2 8 can be used to better accommodate objects of different sizes. The connecting link 2 is located between four links 1 and has the same shape as link 1 to promote the stability and uniformity of the device. An elastic buffer device 4 is rotatably connected to the outer surface of the connecting rod. The elastic buffer device 4 includes a connecting block and a spring. The size of the elastic buffer device 4 is the same as that of the rollers 7 and is used to prevent the product from falling into the gap or falling to the side and causing damage to the product due to vibration generated during chain transportation.

[0024] Working principle: When using this double-row drive roller top plate chain, the top plate chain is driven by an external motor. The items to be transported are placed on the upper surfaces of top plate 5 and top plate 8 for conveying. When the product is small, the connecting ring 62 set on the bottom surface of the material box 6 is inserted into the connecting groove 52, so that the mounting hole 51 and the mounting hole 61 are aligned and fixed with the corresponding screws. When the entire top plate chain is in motion, the elastic buffer device 4 set corresponding to the roller 7 uses its elasticity to reduce micro-vibration and protect the loaded small items. When top plate 5 and top plate 8 need to accommodate objects of different sizes, the distance between the rollers 7 can be adjusted through the adjustment hole 3 set on the connecting link 2.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
