Polyurethane mixing and stirring mechanism

Abstract

The invention discloses a polyurethane mixing and stirring mechanism which comprises a fixed rack, a heating rod, a fixed box, a loop bar, an arc-shaped scraper blade and a switching valve, wherein astirring barrel is mounted in the fixed rack, a connecting plate is mounted in the stirring barrel, the loop bar is mounted in the connecting plate through a bearing, a third cone-shaped gear is mounted at the top end of the loop bar, the fixed box is mounted at the top end of the stirring barrel, a motor is arranged in the fixed box, an output end of the motor is provided with a rotating shaft penetrating the loop bar through a coupling, a first cone-shaped gear is mounted on the outer wall of the rotating shaft, and first stirring rods are mounted in an equally spaced manner on the outer wall of the loop bar. According to the polyurethane mixing and stirring mechanism, the motor is started to drive the rotating shaft and the loop bar to rotate reversely, so that it is convenient to drivethe first and second stirring rods to mix the polyurethane mixture in the stirring barrel, and therefore, the stirring effect is better.

Description

technical field [0001] The invention relates to the technical field of polyurethane stirring, in particular to a polyurethane mixing and stirring mechanism. Background technique [0002] Polyurethanes are polymers composed of urethane-linked organic units. Although most polyurethanes are thermosetting polymers that do not melt when heated, polyurethanes are also thermoplastic. Polyurethane polymers are traditionally and most commonly formed by dimerization or Isocyanate and polyols are polymerized by reaction. When polyurethane is mixed with the reaction solution, it needs to be stirred by a stirring device. The traditional polyurethane mixing and stirring mechanism can basically meet people's needs, but there are still certain problems. The specific issues are as follows: [0003] 1. At present, most polyurethane mixing and stirring mechanisms on the market have poor stirring effect and can only stir in the same direction, which makes the stirring effect of polyurethane mi...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a polyurethane mixing and stirring mechanism to solve the problem that the stirring effect of the above-mentioned background technology is poor, and it can only be stirred in the same direction and cannot be heated to the stirring material, so that the stirring effect of the polyurethane mixture is relatively poor. question
