Detailed Description

The invention is further described with reference to the following figures and examples.

The present invention will now be described in detail by way of exemplary embodiments. It should be understood, however, that elements, structures and features of one embodiment may be beneficially incorporated in other embodiments without further recitation.

In the description of the present invention, it should be noted that the terms "inner", "outer", "upper", "lower", "front", "rear", and the like indicate the positional relationship based on the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Examples

Referring to fig. 1 to 4, a wire conveying roller way comprises a bracket 1 and a row of rotatable rollers 2 mounted on the bracket 1, wherein a chain wheel 3 is connected to one end of each roller 2, and as can be seen from fig. 1, the chain wheels 3 connected to two adjacent rollers 2 are different from each other, and if the chain wheel 3 connected to one roller 2 is on the left side, the chain wheel 3 connected to the adjacent roller 2 is on the right side, and thus the rollers are arranged in a left-right crossing manner. The chain wheels 3 are connected through chains 4, one of the rollers 2 is driven to rotate through a driving device, the driving device of the embodiment adopts a motor 5 with a speed reducer, and the rest rollers 2 rotate by means of the chain wheels 3 and the chains 4 in a transmission mode. When the motor 5 is started, the roller 2 connected with the motor can be driven to rotate, and the other rollers 2 on the left side and the right side of the roller 2 are driven to rotate by the transmission of the chain wheel 3 and the chain 4, so that the purpose of conveying wires is realized.

As can be seen from fig. 1, a chain tensioning device 6 is respectively placed under the chains 4 on both sides of the roller 2 in the embodiment, the chain tensioning device 6 comprises a support 61, a connecting shaft 62, a bearing 63, a tensioning sprocket 64, a height adjusting bolt 65, a connecting plate 66 and a connecting bolt 67, the bearing 63 is fixed on one side of the support 61, the connecting shaft 62 passes through the tensioning sprocket 64 and is connected with the bearing 63, the connecting plate 66 is arranged below the tensioning sprocket 64 and is connected with the support 61 through the height adjusting bolt 65, a strip-shaped hole 68 is formed in the connecting plate 66, the height adjusting bolt 65 passes through the strip-shaped hole 68 and is connected with the support 61, and the height adjusting bolt 65 can be inserted into different positions of the strip-shaped hole 68, so that the height adjustment of the whole chain tensioning device can be realized. The connecting plate 66 is further provided with a connecting bolt 67, and the chain tensioner 6 is integrally connected to the bracket 1 through the connecting bolt 67. Both ends of each roller 2 are mounted on the carriage 1 by means of a mounted bearing 7.

In practical production, when the chain 4 is loosened and jumps, the height of the tensioning chain wheel 64 can be adjusted through the height adjusting bolt 65, so that the chain 4 is supported and tightened, and the machine can be restarted for operation. The wire rod rollgang of this embodiment simple structure is reasonable, convenient to use, and maintenance speed is very fast, reduces the time that the maintenance delays.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may apply the equivalent embodiments modified or modified by the above technical contents disclosed as equivalent variations to other fields, but any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention will still fall within the protection scope of the technical solution of the present invention.
