Description

Coiled plate spreading and winding device for welding distance nails

Technical Field

The utility model relates to a rolling plate spreading and winding device, in particular to a rolling plate spreading and winding device for welding distance nails.

Background

The spiral plate heat exchanger has the advantages of small volume, high heat transfer efficiency and the like, and is widely applied to the technical fields of chemical industry, medicine and the like. When the spiral channel is processed, the distance nails are welded on the steel plate in an equidistant mode, and then welding and rolling are carried out to form the needed spiral channel.

In the moving process of the steel belt, the steel belt can only move to one side of the welding machine in one direction due to the matching of the ratchet wheel and the pawl, so that the phenomenon that the position of the welding nail is deviated due to reverse inertial slipping of the steel belt in the stretching process can be well prevented. Meanwhile, when the total mass of the steel plate on the steel strip coil is smaller and smaller, if the traction force is certain, the movement speed of the steel plate is larger and larger, and the brake component additionally arranged for the purpose can play a certain limiting role on the rotating speed of the rotating shaft, so that the defect that the position of the welding nail is deviated due to overlarge speed in the extending process of the steel plate can be prevented.

However, since the elastic member (spring) is used as the braking member, the elastic member cannot play a role in braking well after being softened as soon as the use time is long, that is, the steel belt cannot be in a tensioned and non-divergent state. Secondly, when the rolled steel belt is pulled and spread by the traction device, the welding surface of the rolled steel belt is not necessarily smooth, so that on one hand, the welding quality of the distance nails can be influenced, and meanwhile, the steel belt with uneven welding cannot be well rolled on a winding drum of a material receiving machine, so that the use of subsequent procedures can be influenced. Such devices are therefore still in need of further improvement.
