Rapid locking mechanism for stirring paddle

Abstract

The invention relates to a rapid locking mechanism for a stirring paddle. The rapid locking mechanism for the stirring paddle comprises a stirring shaft, the stirring paddle, a pressure sleeve, an adhesive tape retaining sleeve, adhesive tapes and two cams, wherein the stirring shaft is arranged in the stirring paddle; a drive pin arranged on the stirring shaft is located in a groove arranged on the stirring paddle; the pressure sleeve is sheathed onto the stirring shaft; the adhesive tape retaining sleeve is sheathed onto the pressure sleeve; the adhesive tapes are arranged between the pressure sleeve and the adhesive tape retaining sleeve; the upper ends and the lower ends of the adhesive tapes are respectively contacted with the top end of the adhesive tape retaining sleeve and the bottom end of the pressure sleeve; the two cams are respectively arranged at both sides of the stirring shaft through a cam pin shaft; and when in a locking state, the bottom end of the adhesive tape retaining sleeve is compressed tightly by the surface at the maximum diameter position of each cam; the adhesive tape retaining sleeve and the pressure sleeve are respectively supported by the upper ends and the lower ends of the adhesive tapes; and the upper end face of the stirring paddle is compressed tightly by the bottom end face of the pressure sleeve. According to the rapid locking mechanism for the stirring paddle, any parts do not need to be disassembled or assembled during the process of installing and disassembling the stirring paddle and the stirring shaft, thus, the stirring paddle and the stirring shaft are rapidly connected and are effectively locked; the stirring paddle replacement time and the stop time of equipment are shortened; and the utilization ratio of a machine is greatly increased.

Description

technical field [0001] The invention relates to a fast locking mechanism for stirring paddles, in particular to a fast locking mechanism for connecting paddles and stirring shafts for stirring and mixing equipment in chemical industry, electronic slurry, lubricating grease, pharmaceuticals, food and other industries. Background technique [0002] At present, in the mixing and stirring equipment used in the chemical industry, electronic slurry and other industries, the stirring shaft is inserted into the stirring shaft installation groove on the top of the stirring paddle, and the connection and fixing of the stirring paddle and the stirring shaft are generally adopted in the following two ways: [0003] 1. Using couplings and bolts; [0004] 2. Pin connection. [0005] The above connection methods need to be fastened with bolts or pins. The first connection method relies on the friction force formed by bolt locking to transmit torque, and the second connection method use...

AI Technical Summary

Problems solved by technology

[0005] The above connection methods need to be fastened with bolts or pins. The first connection method relies on the friction force formed by bolt locking to transmit torque, and the second connection method uses pins to transmit torque, but the above two connection methods are not convenient. For quick disassembly, it is necessary to loosen the bolts or remove the pins to separate the stirring paddle and the stirring shaft, which cannot achieve the purpose of fast locking installation and disassembly
