The utility model relates to a variable frequency control device for a float glass horizontal stirrer. The device is characterized in that the variable frequency control device comprises a frequency converter (4), wherein the frequency converter outputs two paths of alternating current with the same frequency, and the two paths of alternating current are simultaneously connected with and control corresponding horizontal stirrer motors (9, 10) respectively. The input end and the output end of the frequency converter (4) are connected with an input reactor (3) and an output reactor (6) respectively. Magnetic starters (7, 8) are connected between the output end of the output reactor (6) and the corresponding horizontal stirrer motors (9, 10) respectively. The device has the advantages that: one frequency converter simultaneously drives two horizontal stirrers to operate, and the two level stirrers can be debugged to synchronously operate all the time, so collision in the operating process is avoided; the rotating speed and the steering direction of the horizontal stirrers are adjustable; and the control principle is compact and reliable, the adjustment is convenient, and the operation is convenient.
