Problems solved by technology

The disadvantages of metal stirring fan blades are: first, the number of metal stirring fan blades should not exceed 4, which will affect the uniformity of stirring.
Second, the rigidity of the metal stirring fan blade is large, and it is easy to bring air bubbles during stirring, which affects the surface quality of the float product
Third, the resin residue adhered to the surface of the metal stirring fan blade is not easy to remove

Embodiment 1

[0010] Embodiment 1, making 4-leaf stirring fan blades. The thickness of the polytetrafluoroethylene sheet is 0.8mm. The production steps are: first draw the outline of the stirring fan blade on the polytetrafluoroethylene sheet, then use scissors to manually cut out the outline of the four-blade stirring fan blade, and finally drill The central installation hole of the stirring fan blade is inserted, which naturally forms the deflection angle of the fan blade.

Embodiment 2

[0011] Embodiment 2, making 6-blade stirring fan blades. The thickness of the polytetrafluoroethylene sheet is 1mm. The production steps are: first draw the outline of the stirring fan blade on the polytetrafluoroethylene sheet, then use scissors to manually cut out the outline of the 6-blade stirring fan blade, and finally drill out The center mounting hole of the stirring fan blade naturally forms the deflection angle of the fan blade.

Embodiment 3

[0012] Embodiment 3, making 8-blade stirring fan blades. The thickness of the polytetrafluoroethylene sheet is 1.2mm. The production steps are: first draw the outline of the stirring fan blade on the polytetrafluoroethylene sheet, then use scissors to manually cut out the outline of the 8-blade stirring fan blade, and finally drill Insert the central mounting hole of the stirring fan blade, and manually adjust the deflection angle of the fan blade.

Abstract

Belonging to manufacturing technologies of polyurethane floats, the invention relates to a manufacturing method of mixing blades used for mixing polyurethane resin. The method is characterized by employing a polytetrafluoroethene plate to make mixing blades and comprising the following steps of: first drawing the profiles of mixing blades on a polytetrafluoroethene plate, then scissoring the profiles of the mixing blades manually with a pair of scissors, and finally drilling out a central installing hole of the mixing blades. The method of the invention can manufacture a plurality of mixing blades so as to raise mixing uniformity, and bubbles are difficult to be brought in during mixing, so that resin residues on the blades can be easy to remove.

Description

technical field [0001] The invention belongs to the polyurethane float manufacturing technology, and relates to a manufacturing method of a stirring fan blade used for stirring polyurethane resin. Background technique [0002] Polyurethane resin needs to be stirred during the manufacture of polyurethane floats. The stirring blades used are made of metal plates such as copper plates or steel plates. For the structure of the stirring blades, see figure 1 . The production method is to first car out the outer circle of the stirring fan blade, then cut out the outline of the fan blade with iron scissors, and finally manually adjust the angle of each fan blade. The disadvantages of metal stirring fan blades are: first, the number of metal stirring fan blades cannot be more than 4, which will affect the uniformity of stirring. When there are more than 4 fan blades, the root of the fan blades is easy to break. Second, the rigidity of the metal stirring fan blade is large, and it i...
