Abstract: A heat press may include an upper assembly comprising a heat plate, a lower assembly comprising a platen, and a base assembly comprising a hinge mechanism. The upper assembly is pivotably coupled to the lower assembly via the hinge mechanism of the base assembly, according to various embodiments. The heat press may be generally configured to heat and compress, between the heat plate and the platen, a workpiece. A method for a heat press may also include a processor perform various operations, including activating a drive motor to drive an upper assembly of a heat press toward a lower assembly of the heat press to exert a compressive force on a workpiece disposed between a heat plate of the upper assembly and a platen of the lower assembly.

Abstract: The present invention provides a drive device for a middle-high voltage vacuum circuit breaker chassis, which comprises a drive motor (10), a clutch (11) and a drive chain wheel (12); the clutch (11) is installed on an output shaft of the drive motor (10), the drive chain wheel (12) is directly fixed with the clutch (11), and the drive chain wheel (12) is driven by the drive motor (10) through the clutch (11). The drive device further comprises a driven chain wheel (13) and a chain (14) or a belt, the driven chain wheel (13) is fitted over a lead screw (15) of the chassis; and the driven chain wheel (13) is driven by the drive chain wheel (12) through the chain (14) so as to drive the lead screw (15) to rotate together. The drive device further comprises a position locking device (39), which is insertable into a recess (37a-c) on the lead screw (15) to lock the chassis.
