Sheet feeding equipment

Abstract

The invention relates to sheet feeding equipment. The sheet feeding equipment comprises a winding mechanism and a material pushing mechanism; the winding mechanism comprises a rack, a disc body fixedto the rack, a first rotating shaft connected with the center of the disc body, a connecting piece, a first winding frame and a limiting frame; first fixing blocks are uniformly distributed on the first rotating shaft in the circumferential direction, and the inner side of the first winding frame is provided with second fixing blocks corresponding to the first fixing blocks; the limiting frame comprises a limiting frame body and inserting troughs, and connecting rods used for connecting winding plates are arranged at the bottom of the two sides of the limiting frame body; the inserting troughsare formed by cooperating of protrusions at the bottom of the two sides of the limiting frame body and the connecting rods, and the inserting troughs are matched with the winding plates and connectedto the two sides of the winding plates in an inserted mode; and the material pushing mechanism comprises a conveying track, a feeding device and a pressing device, wherein the feeding device and thepressing device are located on the conveying track, the feeding device is arranged on the upstream of the pressing device, and the pressing device and the feeding device are oppositely arranged. According to the sheet feeding equipment, winding of sheets is more orderly, the sheets are attached more closely, and the pressing error caused by displacement is prevented.

Description

technical field [0001] The invention relates to the field of heat exchanger manufacturing, in particular to sheet feeding equipment. Background technique [0002] The plate heat exchanger is a high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between the various plates, through which heat is exchanged. The sheet includes a pressed metal sheet. The sheet metal manufacturing method presses two sheets of different materials through upper and lower corresponding molds to form a sheet metal with corrugations, sealing grooves, etc. that meet the sheet manufacturing requirements. Sheets of different materials are usually wound on a shelf, and then released from the shelf during use, and then transported to the mold by a pusher mechanism for pressing. It is inconvenient to control the diameter of the winding frame in the prior art; secondly, the sheet The winding is not neat enough, which makes...

AI Technical Summary

Problems solved by technology

Sheets of different materials are usually wound on a shelf, and then released from the shelf during use, and then transported to the mold by a pusher mechanism for pressing. It is inconvenient to control the diameter of the winding frame in the prior art; secondly, the sheet The winding is not neat enough, which makes the winding effect not good; and the length adjustment of the pushing mechanism is inconvenient; when the two kinds of thin plates are pushed at the same time, the two thin plates are prone to displacement, which causes errors during pressing, which is not accurate enough
