Description

Smoke box conveying roller installation alignment device

Technical Field

The utility model relates to a smoke box conveying roller mounting and aligning device, and belongs to the field of conveying roller mounting auxiliary tools.

The v-ribbed belt roller machine is provided with a conveyor rail 6 as shown in fig. 3, and conveyor rollers 601 are mounted on the conveyor rail 6, and two adjacent conveyor rollers 601 are driven by a timing belt 602 (v-ribbed belt). Wear occurs between the timing belt 602 and the pulley 604 after a long period of operation, resulting in easy slipping of the timing belt 602. In the process of replacing the synchronous belt 602, as the conveying roller 601 adopts a general-purpose conveying roller such as a G1200 series conveying roller, a spring driving roller shaft 603 is arranged in the conveying roller 601 to pop out, and the roller shaft 603 of the conveying roller 601 can be pressed into the conveying roller so that the roller shaft 603 is separated from two side plate bodies of the conveying rail 6, thereby replacing the synchronous belt 602.

When the conveying rollers 601 are replaced, after the adjacent two conveying rollers 601 are sleeved with the synchronous belts 602, two maintenance staff are required to prop the two conveying rollers 601 towards two sides, one maintenance staff is required to clamp the roll shafts 603 of the two conveying rollers 601 in shaft holes on two side plate bodies of the conveying track 6, and the replacement mode consumes labor force and is low in replacement efficiency.

In order to solve the problems, the utility model is realized by the following technical scheme: the smoke box conveying roller mounting and aligning device comprises a support, wherein a first rack and a second rack are connected to the support in a sliding manner, a first supporting rod and a second supporting rod are respectively and fixedly arranged at one ends of the first rack and the second rack, and arc-shaped parts which are correspondingly clamped with two adjacent conveying rollers are further arranged on the first supporting rod and the second supporting rod;

Gears meshed with the first rack and the second rack are further arranged in the support, and the gears can drive the first support rod and the second support rod to clamp two adjacent conveying rollers to prop up to two sides; one end of a rotating shaft of the gear is provided with a rotating handle, the tail end of the rotating handle is connected with a screw rod in a threaded manner, and the screw rod can be in rotary contact with the side wall of the support to limit the rotation of the gear;

Further, a handle for lifting the transmission end of the conveying roller upwards to align and clamp is further arranged at the top of the support.

The beneficial effects of the utility model are as follows: according to the synchronous belt replacing device, the gear rack drives the two supporting rods, the two supporting rods move to two sides, the two adjacent conveying rollers are supported to two sides, and when the synchronous belt is replaced, the roll shafts of the two conveying rollers are clamped with the shaft holes on the two side plate bodies of the corresponding conveying track, so that the synchronous belt replacing efficiency is improved. Meanwhile, by adopting a gear rack structure, remote stroke regulation and control can be realized, and the synchronous belt replacement of other belt wheels with different wheelbases can be dealt with.

Detailed Description

In order to make the objects, technical solutions, and achievement of the objects and effects of the present utility model comprehensible, preferred embodiments accompanied with figures are described in detail below for understanding by a skilled person.

It should be noted that, in the description of the present utility model, unless explicitly specified or limited, terms such as "mounted," "connected," and the like are to be construed broadly and may be either fixed or removable; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium.

In the drawing, A is vertical (or plumb direction), and B is horizontal.

As shown in fig. 1 and 2, the smoke box conveying roller 601 is provided with a positioning device, when the synchronous belt 602 on the conveying track 6 of the v-ribbed belt roller machine is replaced, after the synchronous belt 602 is sleeved with the belt wheels 604 of the two conveying rollers 601, the two adjacent conveying rollers 601 can be spread towards two sides, so that the roller shafts 603 of the two conveying rollers 601 correspond to shaft holes on two side plate bodies of the conveying track 6, spread and position can be operated by one person, labor force is saved, and meanwhile, the replacement efficiency of the synchronous belt 602 can be improved.
