Bellows seal winding device

Abstract

The invention discloses a bellows seal winding device. The bellows seal winding device comprises an operation platform, a long bellows storage mechanism arranged on one side of the operation platform,a pressure head fixture assembly arranged on the other side of the operation platform, a bellows stretching assembly arranged between the long bellows storage mechanism and the pressure head fixtureassembly, a supporting plate slidably arranged on the operation platform, a first driving mechanism arranged on the lower portion of the supporting plate, a cylindrical gear arranged on one side of the first driving mechanism and capable of being driven by the first driving mechanism to rotate, and a V-shaped pressing sheet fixed to the inner wall of the cylindrical gear, wherein the top of the supporting plate is provided with a sealing belt; the sealing belt covers the opening of the gear, the V-shaped pressing sheet sequentially makes contact with the sealing belt and an inner bellows by moving the supporting plate, and winding is conducted on the inner bellows along with rotating of the V-shaped pressing sheet. Through the bellows seal winding device, fixed-length winding of the bellows is achieved, and the winding precision is high.

Description

technical field [0001] The invention relates to a bellows sealing and winding device, which belongs to the field of mechanical production and manufacturing. Background technique [0002] At present, urea bellows are widely used in the SCR field of the automobile industry. At the same time, customers have different requirements for the use of urea bellows (such as length accuracy requirements, winding position requirements, sealing requirements, etc.), usually using mechanical methods or manual Make a wrap seal. [0003] Often, these wrap-around sealing methods result in imperfect wrapping, or when wrapping, misalignment. Manual winding can also result in ergonomic difficulties for the user. Specifically, users with relatively small hand sizes or relatively small hand strength or wrist strength have difficulty in completing the winding. However, the existing sealing equipment uses the same winding procedure for different bellows, resulting in uncontrollable tape winding ac...
